Abstract: 521,153. Looms. JOHNSON & JOHNSON (GREAT BRITAIN), Ltd., (Johnson & Johnson). Nov. 7, 1938, No. 32275. [Glasses 142 (i), 142 (ii) and 142 (iii)] Vertical looms; letting off warps, take-up motions ; shedding motions; driving arrangements.-In a loom more particularly for weaving gauze fabrics the warp passes from a beam 125, round a driven sand &c. roller 124, and then upwards to the horizontally moving shedding mechanism. Some of the warp threads pass over two bars of the upper harness 42 and the others each through two eyes in the lower harness 43 and then descend to the driven takeup roll 128 and finally to the cloth roll 130 carried by counterbalanced levers 131. The harness 42 is carried by links 54 fast on a shaft 52 and links 55 loose on a shaft 53, while the harness 43 is carried by links 57 loose on the shaft 52 and by links 58 fast on the shaft 53. The shed is V-shaped and the tension of the warp is constant during shedding. The shafts 52, 53 carry intergearing toothed sectors 71, 70 and are oscillated by a crank pin 68.on a shaft 34 which alternately engages slots in discs 72 carried by the shafts 52, 53. Means are provided for locking the shafts 52, 53 when the pin 68 is not in one of the slots. The shaft 34, and .a shaft 35 operating the let-off and take-up rolls 124 128 and the picking mechanism are driven by a shaft 32 from the motor 30. A handle 149 may be thrown into gear so that the loom can be turned by hand, but this can only be done when a clutch in the shaft 35 is out and when the shuttle race is closed. Picking - motions; shuttle races; shuttles checking shuttles.-The shuttle race is of V- section and a part of one side 47 is hinged at 152. The shuttle 76 also is of V-section with a projecting part 172 containing the eye 171 to lay the weft close up to the fell ; no reed for beating up is used. The shuttle boxes are carriages 88 connected by springs 87 to sliding bars 86 pivoted to connected levers 83, 85 oscillated by a cam 77 on the shaft 35. The springs 87 are first stressed then a catch 93 holding the carriage 88 is released and the shuttle given a first impulse. A second impulse is given to the shuttle by driven rollers 100. These rollers 100, also brakes 113 on thecarriage 88 are moved into and out of contact with the shuttle at the appropriate times by cams on the shaft 35. 'Specification 521,286 is referred to.

Title: Improvements relating to electric lever operated switches for alternating current circuits
IPC: H01H23/16
Filed: 1947-12-09
Abstract: 637,837. Tumbler switches. PARSONS, Ltd., C. H., and HANDLEY, G. B. Dec. 9, 1947, No. 32405. [Class 38 (v)] A switch for A.C. circuits comprises a contactbar 34 having secured to its underside by a rivet 40 a blade-spring 39, the ends 41 of which are located in recesses 42 formed by the switch-body 20 and cover 21. The rivet 40 also secures the bar 34 to an insulating yoke 28 slidable on a rod 23 having a head 33 between which and a collar 30, also slidable on the rod and abutting a shoulder 46 thereon, is located a compressionspring 32. Further weaker compression springs 27, 29 are positioned on the rod between respectively, the yoke 28 and the cover 21 and the collar 30, the spring 29 being weaker than spring 27. The collar 30 slides in a bore 30a in the body 20 to guide the rod 23 when operated by a dolly 22 pivoted to it at 24 and having faces 25a, 25b co - operating with the surface of the cover 21. As the dolly commences to move from the " off " position, the rod 23 rises, the springs 27, 29 are somewhat compressed and the blade-spring 39 engages the top of the recesses 42, Fig. 7. Further movement brings the collar 30 against the yoke 28 and further compresses the spring 29. Continued movement compresses the springs 27, 32 and flexes the blade-spring 39, and the bar 34 bridges the fixed contacts 35. The switch is maintained in the " on " position by the dolly face 25b bearing on the cover. On reverse movement of the dolly, the blade-spring 39 unbends and gives an initial small separation to the contacts 34, 35, after which the springs 27, 29, 32 expand and the contact bar 34 moves to the fully open position. Rotation of the rod 23 is prevented by a pin 47 passing through it and engaging grooves 49 in a bore in the cover. In an alternative construction, Fig. 11, the rod 23 has a cranked pin 44 against which press the spring 27 and yoke 28. The cranked end of the pin extends through a plate 45 on the rod and cooperates with a recess 49a in the cover, thereby preventing the rod rotating. In another modification (Fig. 10, not shown), an insulating block is interposed between the contact bar 34 and the blade spring 39 and may serve as the yoke 28. The switch illustrated is a doublepole switch having a pair of bars 34.

Patent GB-337188-A (GB)
IPC: F25B15/10
Filed: 1929-10-26
Abstract: 337,188. Siemens - Schuckertwerke Akt.-Ges. Oct. 26, 1928, [Convention date]. Refrigerating, absorption machines and systems for.-In a continuouslyacting machine surplus liquid refrigerant is stored during the normal supply of heat to the generator for producing cold when the supply of heat is either reduced or cut off. The surplus refrigerant may be stored in, containers 13, Fig. 1, in the evaporator, the necessary absorption liquid being stored in containers 14 in the absorber. The production of the surplus refrigerant and its subsequent absorption may be promoted by decreasing and increasing respectively the cooling effect in the absorber. In a modification, refrigerant vapour passes from the electrically. heated generator 21, Fig. 2, through the pipe 24 to the vapour separator 25. The separator is also heated so as to produce surplus refrigerant which is stored in the containers 38 in the evaporator. In this case, the generator 21 is continuously-heated to maintain the liquid circulation through the absorber 27. The rate of evaporation of the refrigerant can be regulated by controlling the circulation of refrigerant vapour and inert gas between the evaporator and the absorber by variation of the liquid level in the absorber, such variation depending upon the pressure in an electrically-heated heat-insulated vessel 40 having a restricted vapour outlet 44 to the condenser 33 and liquid inlet and outlet pipes 39, 23 respectively connected to the absorber and the generator. An increase in pressure in the vessel 40 effects a higher level in the absorber and a decrease a lower level. In another arrangement, two vapours generators are provided, one to supply the condenser and the other an injector provided in the refrigerant vapour and inert gas circulation pipes between the evaporator _and the absorber. During the storage period both generators are in action, while during the evaporation of the surplus refrigerant only the second generator is in action. In a further modification, two generators with corresponding vapour separators are provided, one separator communicating with the condenser and the other with an injector in the, refrigerant vapour and inert gas circulation pipe between the evaporator and the absorber. In this arrangement, the second generator communicates with an electrically-heated heat-insulated vessel connected to the bottom of the absorber. Potash or soda lye, or sulphonic acid may be used as absorbents.

Title: Improvements in and relating to variable speed gears
IPC: F16H61/02
Filed: 1926-12-23
Abstract: 292,445. Furness, J. A. Dec. 23, 1926. Variable-speed epicyclic gearing of the kind comprising a solid-driving clutch such as 16, Fig. 2, and brakes such as 29 - - 32 for effecting other drives is controlled by selector means involving spring means such as plunger 23, Fig. 1, for holding in action a selected brake or clutch. To change speed, a pedal 21 is depressed which acting through arm 19 turns selector means such as rod 5 against the spring plunger 23 to disconnect the drive. A selector lever 1 is manipulated to bring one of a number of cams 6, 7 over a selected brake or clutch lever 8, 9, 10, 11, or 12. Upon release of the pedal, the selected speed becomes operative. In Figs. 5 and 6 is shown a form of the invention adapted to the changespeed gear described in Specification 276,405. The drive-engaging spring 91 acts to thrust down. wards a pivoted slotted plate 89. There are cams 44, 47, 48 for operating the gear brakes 53 and selector fingers 43, 45, 46 which are suitably operated. In the arrangement shown, these cams and fingers are carried by rods 41, 42 which are slid selectively from a hand gate control 35 so that on release of disengaging pedal 71 the spring 91 makes selected gear operative. If the plate 89 in its descent misses the fingers 43, 45, 46, it moves far enough to operate a lever 75 which has a cam face 80 which brings into action the clutch 84, which locks the gearing solid for that drive. The fingers and cams are so arranged that the plate 89 alternatively engages one finger at a time and so turns the cam rods 41, 42 one at a time so as to operate the brakes 53 singly as required. A neutral results when the finger 43 is over a fixed projection 96 on the gear case and under a tenon 93 on the plate 89, which is thus prevented from descending. Each brake comprises two half-circle shoes simultaneously applied.

Abstract: 942,121. Counters. SIEMENS & HALSKE A. G. Aug. 28, 1962, No. 32932/62. Heading G4D. During a zeroising process transfer wheels are swung out of engagement with the associated lower denomination wheels while remaining engaged with the higher denomination wheels. A flowmeter drives the units wheel 1 through a gear 4. Each transfer wheel has two sets of teeth 5a and a locking element 5b. Transfer is effected when the teeth adjacent a tooth on the locking element are engaged by teeth 11 and notch 10, Fig. 2, of the lower numeral wheel. At zeroising, shaft 12 is rotated in counter-clockwise direction to rock disc 14 so that the locking element 5b frees the lower denomination wheel while the larger set of teeth 5a remains in tip engagement with the next higher wheel. A pin 19 on the shaft 12 rotates hollow shaft 18 so that pawls 20 fall into a slot 16 to zeroise the numeral wheels. A slight rotation of shaft 12 in the opposite direction restores the apparatus to counting condition.

Abstract: 1280580 Digital display systems HEWLETTPACKARD CO 8 July 1970 [9 July 1969] 33112/70 Heading G4H In a digital display system for displaying the results of measurements the number of digits indicated is determined by the accuracy with which the original measurement is made. As described a frequency signal N x  is measured by counting cycles of it and a reference frequency N c  for a time interval in counters 11, 9. From the two counts a quotient is formed in floating point code with respect to an associated decimal point 28. The mantissa digits stored in stages 31-39 are fed via shifting logic 49 to decoder stages 61-69 connected to display units 51-59, the exponent being fed to display logic 30 to energize the appropriate decimal point indicator 44, 46 or 48 and actuate circuit 50 to provide an indication of the proper exponent notation. The number of digits displayed may be controlled by the number of digits in the count in counter 9. This number may be reduced by a factor dependent on the count resolution, i.e. if it is accurate to a count of Œ17 two fewer digits are displayed. In the embodiment described a binary coded signal on conductor 43 representing the number of digits in the reference count less the number of digits in the count resolution is fed to a code converter 45 to inhibit gates 71-77 connected to the shifting logic 49 so that digits representative of greater decimal place accuracy than the original measurement are dropped.

Title: Full Revolution Slewing Mechanism
Inventor: NOLL GEORGE CARL
IPC: F15B15/06
Filed: 1968-07-11
Abstract: 1,179,802. Slewing cranes. KOEHRING CO. 11 July, 1968 [24 Aug., 1967], No. 33126/68. Heading B8B. [Also in Divisions E1 and F1] A full revolution slewing mechanism, for a crane, power shovel or similar machine, to rotate a superstructure with reference to a chassis comprises a ball-bearing 4 with an annular inner race 7 rigidly secured to the chassis and an outer race 8 rigidly secured to the frame 9 of the superstructure. An upright journal 11 is rigidly mounted on the chassis radially inwardly of the bearing 4 and in offcentre relation thereto. Two complementary double-acting hydraulic swing rams 12, 13 react between the journal 11 and pivots 14, 16, respectively, on the frame 9. As shown in full lines the ram 12 is fully contracted, while the dotted lines show the position of the frame 9 and rams 12, 13 when the ram 12 is fully extended. An hydraulic double selector valve 22 which controls the admission of pressure fluid to, and its emission from the ram 12 is shown in position near the pivot 14 and also diagrammatically adjacent the ram cylinder 19. An identical valve 23 controls ram 13. An actuating mechanism for spool 32 of the valve 22 adjusts the spool 32 to its ram expanding and ram contracting positions in response to pivotal movement of the ram cylinder 19 about its pivot-pin 14 in opposite directions. This actuating mechanism comprises an over-centre spring mechanism operatively connected with rocker plate 33 pivoted to the frame 9 and loaded by a spring surrounding a sleeve 43 pivoted to the plate 33 and to the frame 9 at 42. The rocker .plate 33, shown in neutral position, is operated by a lever 52 pivoted to the frame 9 at 53 and connected by a clevis 54 and pivots 56, 61 to the cylinder 19 at a lug 59. The ram 13 has a similar arrangement which is shown with valve 23 in ram-expanding position. With pressure fluid supplied from a pump P<SP>1</SP> and valves 62, 63 set as shown, the ram 13 extends and the frame rotates in the direction of arrow A, this causes the ram 12 to pivot and actuate the valve 22 so as to assist the rotation. The valve arrangements thus operate to cause the rams 12, 13 to assist each other in rotating the frame continuously and unidirectionally, each ram changing from expanding to contracting automatically as it reaches its fully extended or fully contracted position. Flow reversal by shifting the valve 63 manually reverses the direction of rotation. If valve 62 is shifted manually to the right from its turn initiating position (as shown), the pump P1 will be idled and the superstructure may pivotally coast in either direction. A shift to the left will again idle the pump P<SP>1</SP> but will hydraulically lock the rams 12, 13 and so secure the superstructure against turning in either direction.
