Title: A device for generating mechanical vibrations
IPC: G01M7/04
Filed: 1958-12-17
Abstract: 894,598. Oscillation machines. PROCHAZKA, M., and NAVRATIL, M. Dec. 17, 1958 [Dec. 30, 1957], No. 40749/58. Class 35. In a vibration generator for testing articles, pressure of fluid, e.g. air, in either of two chambers 10 or 11 is arranged to pre-stress the vibrator output pin 5, or to support the weight of the article. The volume of the chambers is comparatively large so that it changes little under vibration to keep the spring effect to a minimum; thus the natural frequency of the system is unaffected. The fluid pressure is variable and is transmitted to the pin via flexible, e.g. rubber diaphragms 22, 23 and rigid members 8, 9. Springs 6, 7 serve to locate the pin only. Attached to the pin is a moving coil 4 disposed in the gap between polepieces 2, 3<SP>11</SP> of an assembly which includes a permanent magnet 1. A vibration pick-up is provided comprising three stationary coils 12, 13, 14 and a permanent magnet 15 in the pin 5.

[Also in Division F2] Yarn is forwarded between a driven roller 7 and a driving roller 3 and these rollers are (a) mounted for movement towards and away from each other, (b) arranged for relative axial movement therebetween against the action of spring means and (c) biassed towards each other with a constant pressure by a spring loaded device 17 which enables the rollers to be forced apart when a safety pressure is exceeded, e.g. when a rib of thread passes between the rollers. Further, the circumferential surface of one of the rollers has a raised peripheral rim 5 so that when the rollers are moved together so as to nip a yarn therebetween an edge of one roller first contacts the rim 5 to initiate a driving engagement between the two rollers before they have moved sufficiently together to nip the yarn. As the rollers move together, the edge of the roller moves down the sloping side of the rim 5 with relative axial movement between the rollers. As described, the driving roller with the raise rim 5 comprises a hard chromium plated steel sleeve 4 providing the working surface thereof. The driven roller 7 comprises a plastics coated metal ring 46 which is mounted on bearings on an eccentric boss. The boss is rotated by handle 6 to move the rollers 3 and 7 towards and away from each other. The spring loaded device 17 comprises a hollow cylindrical housing 19 having a spring seating (20) which is axially slidable and lockable in a position by screws (21). The seating (20) has a partition (25) with two springs (26, 27) one at each side of the partition. Spring (26) provides the constant pressure between the rollers.

Abstract: 1512218 Electric control of sewing machines SINGER CO 6 Oct 1975 [26 Nov 1974] 40856/75 Heading G3N [Also in Division H1] The pattern of stitches to be sewn by a sewing machine is selected by a control circuit comprising switches 52A-52G, Fig. 2, operated by press buttons 22, Fig. 1, on the sewing machine to select one of seven groups of four patterns, and a sliding switch 63 displaceable by a control wheel 24 into one of four positions to select one of the four patterns in the selected group. The switch 63 provides binary signals on leads 100, 101 to a latch 91 which also receives inputs 97-99 derived by combination gates 102-104 from the switches 52B-52G. The latter applies corresponding binary signals on leads 92-96 to address memory 110 which is programmed to provide outputs on leads 120 to select the desired patterns. The switches 52A-52G are connected to a NAND gate 87 which gives an output when any switch is closed. This triggers one shot 89 to operate latch 91. Leads 130-132 from the memory repeat the inputs on leads 97-99 and decoder 135 causes a corresponding light diode 26A-26G to be illuminated above the operated push-button to indicate on a panel 25 which of the seven groups of four available stitch patterns has been selected. One of the four is selected by turning wheel 24, the panel moving with the wipers of switch 63 so that the selected switch pattern is indicated by being positioned under a tinted strip on a transparent cover in front of the panel 25.
