Title: Roller clutches
Inventor: BOWCOTT ROY PRICE
IPC: F16D41/066
Filed: 1984-07-13
Abstract: In a roller clutch comprising an outer race 11 having therein a plurality of circumferentially spaced cam forms 12, an inner race 14, a cylindrical roller 15 interposed between the outer surface of the inner race and each cam form respectively of the outer race, a spring abutment 13 disposed adjacent each of said cam forms, and a spring 19 acting between each roller and the respective spring abutment, the clutch is characterized in that each spring 19 is a helically wound spring and acts against is respective roller 15 through the intermediary of a synthetic resin slipper 21, each slipper 21 having extending therefrom an arcuate synthetic resin spring guide 22 which extends through its respective spring 19 and is slidably received in a bearing bush 17 in the respective spring abutment 13, each slipper/spring guide assembly 21, 22 being guided for circumferential movement relative to the outer race 11 by the bearing bush 17 at one end, and by engagement of the slipper 21 with the outer race 11 at the opposite end. The arrangement thereby minimises the clutch hysteresis. <IMAGE>

Title: Digital-to-analog converter useful in a television receiver
Inventor: WINE CHARLES MARTIN
IPC: H03M1/00
Filed: 1984-07-24
Abstract: A digital-to-analog converter suitable for use in a television tuning system for converting bits of digital word to a corresponding tuning voltage includes coarse and fine digital-to-duty factor converters (816, 820) responsive respectively to and least significant bits of the digital word. The amplitudes of the resulting pulse signals are differentially weighted, e.g., by standard tolerance resistors (826, 828) (+/-10%), such that the maximum average DC potential of the fine signal is greater than a single increment of the average DC potential of the coarse signal. The weighted signals are combined and filtered by a lowpass filter (824) which derives the tuning voltage. This deliberately results in non- monotonicity but without a significant reduction in resolution. To substantially reduce the effects of the non-monotonic increments in disturbing the analog output signal, the value of the digital word in counter (810) is rapidly incremented during the occurrence of each of said non-monotonic increments. The imminence of such increments is detected (832) from the LSB values, whereupon flip-flop (834) causes the output voltage to be stored (836) and the counter (810) switched over to a fast clock (840). Resetting occurs when comparator (838) detects that VOUT has regained its stored value. <IMAGE>

Title: Elasticized non-woven fabrics
Inventor: SOKOLOWSKI ROBERT CHARLES
IPC: D04H1/42
Filed: 1986-01-16
Abstract: An elasticized non-woven fiber material is made by combining one or more textile fibers with one or more elasticizable fibers and bonding the combined fibers together. The resultant web of bonded non-woven fibers is then heat-treated to heat-shrink the elasticizable fiber and recover its elasticity thereby shrinking the fibers and the web of material. An elasticized non-woven fabric made by the described method is also provided. Upon shrinking the elasticizable fibers gather and pleat the textile fibers. The textile fibers may be of synthetic organic polymeric materials, processed natural materials or a combination thereof. The elasticizable fibers are usually synthetic polymeric elastomeric materials. Melt blown fibers may additionally be combined with the textile and elasticizable fibres. Latex spray or sonic wave bonding techniques may be used. A web article may be formed prior to heating.
