Title: Improvements in means for generating electrical time base impulses
IPC: G04C3/04
Filed: 1945-08-23
Abstract: 599,218. Electromagnetic interrupters. JAMES, K. Aug. 23, 1945, No. 21582. [Class 38(v)] In an electromagnetic interrupter used for generating timed impulses the closure of the circuit to an electromagnet 16 causes an impulse to be given to a balance wheel 10; the circuit is broken towards the end of the impulse and restored by the return action of the balance wheel. The closure of the circuit through contacts 13, 14 energises the electromagnet 16 whereupon an armature 17 is attracted and a stop 18 moved so as to allow a cantilever spring 15 to give an impulse to a lever 1, pivoted at 3, through the engagement of the contacts 13, 14. The lever 1 carries a wheel 6 which engages a pin (not shown) on the balance wheel 10 and sets it in motion. After a small movement the spring 15 is brought to rest by the stop 18, but the lever 1 continues to move and the contacts 13, 14 separate. The electromagnet 16 is deenergised and its armature 17 returns to its original position pressing back the spring 15 and contact 14. On the return movement of the balance wheel its pin engages the wheel 6 and brings the lever 1 and contact 13 back to its original position in which it engages the contact 14 whereupon the cycle recommences. In circuit with the magnet 16 may be a " follower " magnet 40, Fig. 6, the timed impulses in which cause a pawl 45 to rotate a ratchet wheel carrying cams such as 50, each of which co-operates with a spring contact 52 to make a circuit when it drops into a notch 51. Alternatively a circuit may be broken instead of made by the notch 51 or the cam may co-operate with two spring contacts 52 at points slightly spaced apart. The circuit .between the contacts 52 is then closed only when one contact is in a slot 51 and the - other out of a slot. Frequency depends on number of slots 51.

Title: Transistor amplifier circuit
IPC: H03F1/34
Filed: 1959-06-24
Abstract: 864,806. Transistor amplifier circuits. COMPAGNIE FRANCAISE THOMSON-HOUSTON. June 24, 1959 [June 24, 1958], No. 21696/59. Class 40(6) A transistor amplifier comprises an emitter follower stage feeding a push-pull stage through a transformer having a low leakage inductance, negative feedback being applied from the pushpull stage to an earlier stage. The Figure shows a common emitter input stage 12, feeding an emitter follower stage 15 which in turn feeds a push-pull output stage 17 through a bifilarly wound low leakage inductance transformer. The combinations of the emitter follower stage and the transformer can be made to have a low phase shift so that negative feedback can be applied through 25 to stage 13. In addition, as the output stage is driven from a voltage source rather than a current source, a more linear operation is obtained.

Title: Combined sewing and trimming mechanism
IPC: D05B37/04
Filed: 1949-08-25
Abstract: 667,044. Sewing machines. COLUMBIA SEWING MACHINE CORPORATION. Aug. 25, 1949 [Sept. 4, 1948], No. 22100/49. Class 112. [Also in Group XXIV] Trimming; presser-feet.-An attachment for trimming or pinking the edge of work being sewn in an ordinary machine comprises relatively movable cutting blades actuated from the needlebar; the operating mechanism preferably provides for actuation of the blades only at every other stroke of the needle, or less frequently, and also for putting the cutting mechanism out of action; in the embodiment described the cutting blade moves horizontally, and the work is bent upwards at the edge by the presser-foot or a separate guide. In the arrangement shown, looking in the direction of feed, the fixed blade is formed by two sharpened edges of a triangular hole in a plate secured in a vertical plane to the right-hand side of the presser-foot shank 15, which is correspondingly apertured, and the moving knife 23, of V section, has an extension which is guided in an upward enlargement of the hole in the fixed blade. The edges of the pieces of fabric being sewn are bent up and guided by a slot 21 in the presser-foot 16 to lie in a suitable position relative to the knife 23; in a modification, a narrower presser-foot of ordinary form is used, with a depending guide plate close to its right-hand side to guide the fabric edges. The knife 23 is reciprocated by a lever 34 pivoted at 35 and having its other arm formed as a toothed sector for engagement with a similar sector on a spindle 51 which is oscillated from the needlebar ; the arm 34 and the mechanism are carried by a bracket 24 clamped on the presser-bar, and the knife 23 is pressed downwards by a spring plunger 43 mounted in this bracket. The mechanism comprises a member 48 pivotally, attached at one end to the needle-bar 5 and supported from the spindle 51 at the other end by a link 50, an arm 53, linked to the member 48, rotatably mounted on the spindle 51 and carrying a pawl 54, and a member 55, fixed to the spindle 51 and formed with an abutment for engagement by the pawl 54 and an opposing abutment for engagement with a stop screw on the arm 53 by which the member 55 is returned to its initial position with the arm 53. In order to provide that the blade 23 is not operated at every stroke of the needle, the pawl also engages a ratchet wheel 56, which is free on the spindle 51 and provided with a detent 71, and the notches of this ratchet wheel are of different depths, so that some of them prevent the pawl 54 from descending into engagement with the member 55, the ratchet wheel thus providing for a predetermined sequence of effective and idle strokes of the arm 53; the pawl 54 can be raised and held clear of both members 55, 56 by a finger lever 65 with a cam surface engaging the arm 53, when it is desired to sew without cutting.

Title: Improvements in binders for loose leaves and the like
IPC: B42F13/20
Filed: 1939-07-29
Abstract: 516,108. Loose-leaf binders. HANDLER, F. July 29, 1939, No. 22106. [Class 146 (i)] Relates to binders of the kind comprising a channelled member 4, Fig. 1, . adapted to form the back of the binder, and a series of open rings 10, Fig. 2, joined by a connecting-member 8, which are slid lengthways on to the member 4, so that the free ends of the rings and the connecting-member lie in the channels 7 therein. According to the invention, the rings and the connecting-member are made of wire, instead of from strip material, as heretofore, so that they may be formed by bending instead of by stamping. The channelled member may be built up from separate strips, or may be formed by a member bent into dovetail form. The ends of the rings may engage recesses in the channelled member to prevent the connecting-wire from sliding out, or the wire may have a kinked part 15 for the same purpose. The channelled member may have slots 24, Fig. 8, in one edge, so that the rings may be turned until their ends enter the channel, and the wire then slid lengthways. The rings may be of oval or flattened form, whereby the edges of the leaves are held straighter than in the case of circular rings.

Filed: 1971-04-19
Abstract: 1347905 Jacquards APPARATEFABRIK AG HUTTWIL 19 April 1971 [19 Feb 1970] 22111/71 Heading DIE A double lift open shed Jacquard comprises double hooks 3 each leg of which has a tongue 13 cooperating with oppositely moving griffe knives 10, 11 and a tongue 12 cooperating with open shed blades 14, 15, stationary guides 16 for the tops of the hook legs 8, 9, movable guides 32, 33 which act on the ends of selected hooks to entrain or release the tongues 12 from the open shed blades 14, 15 and presser needles 1 for entraining the tongues 13 with the griffe knives 10, 11, each leg 8, 9 of a hook being actuated by a presser needle 1 from different sides of the Jacquard. Each open shed blade 14, 15 is movable diagonally downwardly and inwardly of a hook and each hook 3 has a bottom bridge piece 5, with lifting cords 7, resting on a bottom board 4. In use a hook 3 having its leg 8 selected from the left of the Jacquard has that leg 8 moved away from the stationary guide 16 so that the tongue is in the path of the ascending knife 10, the open shed blade 14 then descends to provide clearance between it and the ascending hook. The hook may thereafter descend with the knife 10. If it is desired to maintain the raised hook in the open shed position a selection from the right side of the Jacquard causes a presser needle 1 to move the leg 9 free of the guide 16 so that the tongue 12 engages the ascending open shed blade 15 and the knife 10 then descends leaving the hook in the open shed position. To ensure that the rising knife 11 does not foul the tongue 13 of the leg 9 the movable guide 33 moves to the left, the open shed blade 14 ascends, the blade 15 descends transferring the tongue 12 to the blade 14 and the guide 33 returns to the right allowing the leg 9 to abut the guide 16 and provide clearance between it and the rising knife 10. If it is desired to return the hook in the open shed position for a further pick the hook is in a similar manner transferred to the open shed blade 14 whilst the knife 10 ascends and the knife 11 descends. The hooks are lowered by moving the open shed blade that retains the hook downwardly whilst its corresponding lifting knife is in its upper position thus transferring the hook to a descending knife.

Title: Improvements in or relating to apparatus for use in conveying and elevating goods
IPC: B65G19/22
Filed: 1955-08-03
Abstract: 785,566. Elevators for sacks. MILLER, K. Aug. 3, 1955, No. 22343/55. Class 78 (1). In a sack elevator comprising an inclined trough 8 up which the sacks 37 are pushed by cross bars 14 extending between a pair of endless chains 13, the cross bars are arranged to travel at such distance in front of the trough that they engage the outer lower corners of the sacks to enable the trough to be steeply inclined. The trough comprises side members 8a and skids 8b supported on brackets 8c. The trough is secured to side members 10 of a framework 10a, 10b through spacers 9. The framework is supported by a strut 6 on a base 5 having steerable wheels 7. The chains 13 are passed around upper and lower sprockets 12, 12a, the former being mounted on separate shafts 11 journalled between the side members 8a, 10, to leave the trough unobstructed, and driven by chain gearing from a shaft 26 mounted in brackets 25 on the framework. A secondary conveyer 4 is mounted on the shaft 26 by bearings 27 in its side members 30. The secondary conveyer comprises chains 29 passed around sprockets on shaft 26 and at the outer end of the members 30 and cross bars 32 extending between the chains for pushing the sacks up a shallow trough 33. Since cross bars 32 are close to trough 33 the latter is less steeply inclined than the trough 8. The height of its delivery end is adjusted by a stay 45 pivoted at 48 to the frame of conveyer 4, the lower end of the stay being guided in longitudinal slots in the strut 6 and being raised and lowered by a pair of cables 49 passing over pulleys 44 to a manually operated winch gear 38. Conveyer 4 may be lowered into an out-ofuse position against the strut 6. The conveyers are driven by a motor 24 driving shaft 26 through chain gearing 22. The chain gearing between shaft 26 and the shafts 11 is such that chains 29 travel faster than chains 13 so that sacks picked up by cross bars 32 are removed quickly from the cross bars 14 to prevent jamming.
