The article evaluates the LeeP Plastic Composite Springs from Lee Spring Co.

Reports on the use of miniature air springs to provide proper frequency for vibrating machinery. Technical challenge in curing process; Design of conveyor frame; Benefits.

Clutch engineers saw an opportunity to shrink a standard clutch size and improve its performance under racing conditions. But the design proved tougher than the concept. At first, the design seemed straight-forward: increase the clutch face loading, and beef-up the diaphragm spring that holds the clutch faces engaged. Then came the challenges. For one, the diaphragm spring pressure couldn't be increased easily to achieve the correct height to thickness ratio of 1.6:1, so the two springs were nested. An anti-friction coating of some sort was demanded.

The article focuses on a Sun beam Radiant Control Toaster which automatically stop and found that the return springs that lifted the toast had weakened, it can be repaired by spring bracket.

In this article, the author, and engineer, relates his experience attempting to fix the design of a faulty spring clutch used in a copier. He explains that previous engineers had estimated the clutch's torque. He chose to use a clutch made of ductile heat-treated steel. Torque was transmitted in the clutch from an input arbor to an output arbor.

The article reports that a young man litigated a bike manufacturer after he was injured badly when he lost control of the bike and piled up in the U.S. According to the investigation, the spring on the kickstand was missing which resulted accident. It is said that the plaintiff claimed to have replaced the spring before the accident.

The article presents information about the PRD3-ANB-C-DEF pressure regulator developed by Beswick Engineering Co. Inc. In order to keep the size small, the regulator uses nested stages. Due to its spring arrangement, the regulator is capable of handling a range of regulated output pressures. This regulator has an improved valve design.

Provides information on the Power Clamp spring pressure DIN rail mount terminal block from WAGO Corp. Overview of the coil spring used in the power clamp; Maximum power that can be handled by the power clamp; Design applied to accommodate large conductors.

Answers several questions on electronics. Creation of Slinkies™ flat wound springs; Electric field imaging device from Motorola; Fade of black anodized aluminum extrusions under the fluorescent light.

Presents information on the Associated Spring's catalog of Stock Precision Engineered Components (SPEC) that allows quick identification of the right spring for a given application. Features of the SPEC Select II; Availability of the catalog.

Provides information on the leveling valve for the suspension system of heavy trucks developed by Paul O'Reilly of Barksdale Inc. Action of air springs control; Features of the leveling valve.

Provides information on the technique developed by Smalley Steel Ring Co. in designing a wave spring. Challenges encountered in designing the wave spring; Use of computer software in the design method.

Presents a pre-stressed Belville spring design. Advantages offered by its disengagement of safety coupling.

Focuses on the twinspring, which is made from alternating coil sets, allowing for flexibility. Description of the design of the twinspring; Contact information.

Reports on Geri Engineering Inc.'s use of CADKEY and CADKEY ANALYSIS software for spring design. Problems with the spring in GRiD Systems' battery-powered data collector; Benefits of using the software.

Reports on the use of nitrogen-filled springs from Stabilus to simplify the design of the passenger door of Boeing's 777 airplane. Advantages of gas springs over coiled springs; Views of design engineer Michael Flemming on the design of the gas springs; Seal design of the spring; Software used in the development of the design; Installation to the door assembly of the aircraft; Features; Testing.

The article presents information about beam-bending spring. Belleville washers and leaf springs flatten out under load. Conversely, the universal loading spring is flat to begin with; flexing occurs once load is applied. Weight-bearing fulcrums, equidistant and unopposed on each surface, distribute the load. Varying the number, spacing, and height of these nubs--as well as the thickness and flexibility of the spring itself--controls the amount of deflection. At full deflection, the nubs act as stops to prevent overstressing. The entire spring, including the rounded nubs, may be cast, molded, or stamped to meet load specifications.

The article reports that brass fitting's captive gasket replaces multiple threads for shorter, more uniform mounting heights. Also, it reports that unusual male fitting threads quickly into female fittings of different form and pitch. A predesigned interference between the "mismatched" threads locks the assembly, while a belleville spring takes care of sealing. Furthermore, design is good for at least four major pipe threads: NPT, NPTF, G(PF), and rc(PT).

The article reports on a new technology snap fastener. Unique geometry of a clover spring gives this bistable fastener uniform snap and high breakaway force. Stacking the springs lets the design engineer meet most latch-and release requirements. Application of the predetermined force snaps the fastener to its other stable position, releasing a door, hatch or structural component. Many automotive, aerospace and consumer applications are possible.

Presents a trivia on reading a spring balance being hung from the ceiling by a rope.

Constant force brush springs, from Associated Spring and Barnes Group Inc., are found in all sorts of small, FHP dc motors, particularly in automotive applications. The typical spring is a multipart assembly. Formed from a single strip of spring material, this double constant force spring does the job in less space and at much less cost. Because the coil of the spring is not added to the length of the brush, motor housing diameter can be reduced by 10 to 20%. Cost is estimated to range from 3.5 to 5% of the cost of existing assemblies.

Features the two smaller sizes of Spirawave Wave Springs added by Smalley Steel Ring Co. to its SSR series.
