Title: Rotary hook and bobbin-case device for sewing machines
IPC: D05B57/14
Filed: 1934-07-24
Abstract: 421,957. Sewing machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. July 24, 1934, No. 21610. Convention date, May 12. [Class 112] In a rotary hook device provided with a circular raceway for the cylindrical bobbin case of the type described in Specifications 12609 /11 and 18023/11, [both in Claas 112], the bobbin case is provided with a bearing rib with a gap forming a stationary spur for detaining the needle loop seized by hook. The bobbin thread tension device is as described in Specification 370,304. The machine illustrated has the usual horizontal hook shaft 5 making two revolutions to each complete reciprocation of the needle 1. The hook shaft carries on a cupshaped body 6 having a raceway 7 for the bobbin. The raceway is cut away at one side to form a hook-seizing beak 8 with an inclined loop-spreading inner edge 9. The peripheral bearing rib 13 of the bobbin case element 14 is journalled in the raceway 7. The case has a loop detaining spur 16 and a flange 17 with a rotation-restraining notch 18 entered by a tongue 19 on the bar 20. The bobbin case element 14 has a bar 24 carrying the usual stud 25 by which the mating bobbin-case element 28 carrying the bobbin 29 and the under-thread tension device 30 is attached. A chamfer 31 on the bobbin case facilitates the spreading of the needle loop.

Title: Stepping motors
IPC: G04C13/11
Filed: 1976-05-25
Abstract: The stepping motor for pulse-controlled electronic clocks is provided with stator laminates of unsplit sheet metal, which have recesses for the rotor at the open ends of the stator laminates. In order to create a pulse-controlled stepping motor which can be assembled at a low assembly cost and requires only a low drive power, the core laminates (1) of the stator have allocated to them externally attached additional laminates (2) whose tabs (21) and steps (22) cover the air gap (11) of the core laminates (1) and whose end opening (23) is smaller than a quarter of the circular cut-out which holds the rotor. In this case, the drive coil is advantageously pushed over the one limb of the stator, after said stator has been bent laterally. <IMAGE>

Abstract: 704,149. Feeding sheets. CROWN CORK CO., Ltd., and BECK, N. Aug. 31, 1951 (Sept. 7, 1950], No. 22113/50. Class 100 (1) In a labelling machine wherein each label is de detached from a stack of labels by a reciprocating suction de vice and conveyed to an article to be labelled, the suction de vice 20 is carried by a pistor rod 12 which is connected tc a piston through a lost-motior arrangement, and the suction device 20 can dwell at the position of the stack throughout the period of the lost motion, The machine comprises a base 10 in which a cylinder 11, Fig. 2, is located, and a hollow column 13 supported on the base serves to support the label stack 18, and to act as a vacuum reservoir means between a pump, and the cylinder 11. A hollow cross-head 17, attached to the piston rod 12, slides vertically on rods 16, and carries two rotary arms 20 having suction pads 21, these arms being rotated in known manner by rack and pinion means 22 when the head 17 is reciprocated, so that a label is taken from the stack 18 and placed on a bottle on a reception table 19. The labels pass a device 23 where gum is applied thereto. The piston rod 12 is hollow and passes into the cylinder 11 where a piston 24 is slidable thereon between two fixed abutments 25, 26 constituting the lostmotion device. The suction pump 14 (not shown) is connected alternately with each end of the cylinder 11 through the hollow column 13, a pipe 52, a treadle-operated valve, a pipe 43, and a slide-valve arrangement 32, 33. The valve 32 is reciprocated in a cylinder 33 by means of a rod 34 connected to a " snap-over " link device 35 operated by a rod 37 having abutments 39, 40 thereon engaged by a tappet 38 secured to the piston rod 12. The cylinder 33 is connected to the cylinder 11 by a passage 44 at the top, and a pipe 46 at the bottom, and the piston 24 is actuated by evacuating one end of the cylinder, and opening the opposite end to atmosphere. The cross-head 17 is provided with an adjustable plunger 27 (not shown) adapted to enter the spring jaws of a fixed collet when the head 17 is in its uppermost position. The head 17, and therefore the suction device 20, is thus frictionally-retained in the upper position adjacent the stack 18, until the piston 24 strikes the lower abutment 25 on the piston rod 12. This gives the suckers more time to detach a label from the stack. Suction is established to the pads 21 through the hollow arms 20, cross-head 17, rod 12, and cylinder 11 ; on the upward stroke of the piston 24, the pads 21 are connected to atmosphere along the same path.

The liquid only partially fills the interior of the (evacuated) fuse casing, which is arranged so that a continuous evaporationcondensation cycle is produced, so cooling the fuse element and reducing Joule effect losses. In another embodiment, Fig. 2 (not shown), the body (8) is completely immersed in the liquid filler (10) to prevent premature drying of the pores adjoining the fuse element (9). In another embodiment, Fig. 3 (not shown), the body 19 of quartz sand is separated by the walls of the casing (16) by a cylindrical grid (21) which prevents the shock-wave produced when the fuse blows, from reaching the casing walls, which need not be impact resistant. In an alternative embodiment, Fig. 6, sealed metal casing 22 has the upper lead 23 as an extension thereof. An auxiliary electrode 27 made as a thin metal spiral surrounding the fuse element 26, and maintained at a voltage difference therewith, sets up an electric field which affects the boiling point of the liquid filler and thereby improves the current rating of the fuse. In Fig. 7 (not shown) the fuse element is cylindrical (33) and has disposed within it an auxiliary electrode (34).
