Title: Improvements in or relating to cinematograph projectors for films bearing sound records
IPC: G03B31/00
Filed: 1935-10-23
Abstract: 443,089. Kinematograph apparatus. DEBRIE, A. L. V. C., 111, Rue St. Maur, Paris. Oct. 23, 1935, No: 29256. [Class 97 (i)] A projector for films having perforations in one margin only, and a sound record in the other margin, is adapted for films having the sound record either in the left margin or the right margin, by constructing it so that the film may be threaded with the sound record in correct lateral position at the sound gate, and may be twisted, if necessary, to place the image in correct lateral position in the picture gate, the intermittent feeding pins being capable of displacement or replacement so as to engage the perforations whether they -are then on the left side of the gate or the right. The twisting may occur both at the upper and the lower film loops, or only at the lower loop, the whole of the film above it being reversed, and the upper sprocket being reversed on its spindle. The feeding pins 12, 13 may be carried by a frame or bar 8 having lugs 9 by which it is pivoted to lugs on an arm 5 extending from a carriage 1 vertically reciprocable by a cam 2. One or both of the lugs 9 may be formed with two flats 14, 15 which alternatively engage a spring 16 to hold the frame 8 in the position shown, so that the pins 13 engage perforations in one margin of the film 20, or in the broken line position, so that the pins 12 engage perforations in the other margin. If the frame 8 is in incorrect position for the film perforations, the engagement of the film and pins when the film has been threaded, causes the frame to rock into the correct position.

Abstract: 494,454. Cow-milkers. AKTIEBOLAGET SEPARATOR. Oct. 28, 1937, No. 29480. Convention date, Dec. 3, 1936. [Class 84] A milking-machine pulsator comprises in combination a primary pulsator of the type having a slide 4 or a system of valves controlled by one or more diaphragms or bellows 1 and a secondary pulsator of the type in which channels of communication within the pulsator are brought about by a slide 9 reciprocating in a cylindrical bore, the pulsators being so associated that the pulsations generated by the primary pulsator act directly on the secondary pulsator which in turn generates pulsations which act on the teat cups 15. As shown, the primary pulsator comprises a pair of bellows 1 housed in separate chambers 18, 19, each of which communicates with pulsation chambers 16, 17 through channels 16a, 17a. The pulsation chambers 16, 17 each communicate through nipples 13, 14 with separate groups of teat cups. The bellows communicate by a throttled channel in their support 20 and collapse or expand according as atmospheric pressure or vacuum prevails in their chambers, the air passing from one bellows to the other. The bellows are connected by a rod 2 and reversing mechanism 3 with slide 4 which is arranged to put a channel 5 alternately into communication with a channel 6 communicating with vacuum and a channel 7 connected to atmosphere. The channel 5 communicates with a chamber 8 at one end of the cylindrical bore and the pulsating vacuum therein causes reciprocation of slide 9 which connects the pulsation chambers 16, 17 alternately to vacuum through an intermediate portion in constant communication through a nipple 11a with a vacuum source and alternately to atmosphere through a channel therein which conducts air to two annular grooves 11, 12. To prevent milk penetrating from the nipples 13, 14 into chambers 18, 19, communication between each of these chambers and the corresponding pulsation chamber 16, 17 may be effected through a narrow tube 22, Fig. 3, projecting into a chamber 21.

Abstract: 1,106,472. Manipulators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 26 July, 1965 [31 July, 1964], No. 30276/64. Heading B4Q. A manipulator comprises a beam 11 rotatably mounted by means (not shown) at its central portion in a shield and having pivots 16, 17 at its ends respectively supporting a master arm 12 and slave arm 13. A tube 18 rigidly fixed in the beam slidably supports a sleeve 21 connected by links 24, 28 to the upper ends of the master and slave arms whereby movement of the master arm 12 about pivot 16 causes movement of slave arm 13 about pivot 17. The master arm comprises an upper portion 25 and a lower portion 32 rotatable about its longitudinal axis on the upper portion by means of a bearing 36, this rotational action generating an hydraulic pressure which is transmitted via conduits 49, 20, 84 to the slave arm to cause corresponding rotational motion of the jaws 74 relative to the upper portion 29 of the slave arm. (The conduit 20 is hidden by a conduit 19 in the drawing.) The hydraulic system includes, in the master arm, a piston 43 biased by a spring 46 in a bore 45 and carrying a cam follower pin 42 guided in slots 41. The pin 42 co-operates with an annular cam surface 34 rigid With the arm portions 25 whereby rotation of the arm portion 32 causes movement of the piston and hydraulic pressure is transmitted to the conduit 49 through channel 47 and port 48. In the slave arm, the conduit 84 is connected to a port 83 to influence a ram 75 slidable in a bore 79 and biased by a spring 80. The ram is rigid with a sleeve 85 carrying pins 86 cooperating with helical slots 87 in the lower portion 73 of the slave arm, this portion 73 being rotatable on the upper portion 29' and carrying the jaws 74. The jaws are also closed hydraulically by a lever 51 controlling an hydraulic actuator 53 controlling the movement of a valve 66, this valve controlling hydraulic pressure transmitted through further conduits 49a, 19, 93 to a further spring-biased ram 76 in the slave arm.

Title: Counter means
IPC: G07C1/02
Filed: 1974-07-09
Abstract: 1449523 Counting apparatus J HENGSTLER KG 9 July 1974 [18 July 1973] 30331/74 Heading G4T  Fig. 1 shows a counter unit 1 which constitutes a plug-in module including a counter mechanism or digit wheel set 2, a signal area 3, an identification area 4, and a slot 5 for receiving a punched identity card 6, Fig. 4. Such a counter unit is used particularly for recording the passing of time in organizations having flexible working hours. The margin of the card has holes 7 which allocate the card to a specific counter and to a specific person or item. Fig. 5 shows code detector elements 8a which are replaceably mounted in resilient holders 10 by end pins 9. The code is selected by snapping detector elements into associated receiving slots. Card 6 cooperates with stop fingers 12 and switching fingers 13 with holes in card 6 to allow the card to be inserted providing the proper hole code is used. The punched card can be located in one of two positions because of detent spring 14a cooperating with one of the detent notches 15a. The notches have different elevations thus closing switch contacts when card 6 is inserted. Fig. 8 shows a plan view of a complete arrangement of snap-in code detecter elements 8a in receiving slots 11. Fig. 11 shows an embodiment using a rachet mechanism 17, 18 and a pulse-generating circuit. In this case a card is inserted and removed when an employee arrives and when he leaves. In the former embodiments the card has to be left in the counter unit. Fig. 12 shows how the use of a card having slots 20 instead of holes allows it to enter a sufficient distance to operate reset tie rod 22. Figs. 15 and 17 show how movement of rods 22 disengages drive wheels 23 from digit wheels 26. Also levers 24 acts on cams 25 to reset the wheels 26. One of the digits has a final drive wheel and is therefore not reset. In a further embodiment, Figs. 19-22 (not shown) a locking pin (28) is used to lock a stepping rocker (30) so there is no carry from the non-resettable part of the counter during the reset operation. A further embodiment Fig. 23 (not shown) has two digit wheel sets (2) and (32) driven by a common drive wheel set. The additional counter is used to record partial times worked on a given job and can read out for a recording of the data. The means for reading out can be linked to a printer for printing job time tickets. In this embodiment a punched card (33) is coded at both ends. A. first end starts the counting and a second end initiates the printout operation which may be succeeded by an automatic reset if necessary.

Abstract: 334,742. International Harvester Co., (Assignees of Pearson, C.). Dec. 5, 1928, [Convention date]. Mowing-machines. - A mower attachment is secured to the draw bar of a tractor in such a manner that should the cutter bar strike an obstruction an automatically acting release coupling becomes uncoupled and the cutter bar and mower attachment swing back as a whole to minimize the impact with the obstruction. The ends of the U-shaped draw bar 24 are pivoted in plates 23 attached to casings 18 for the gear driving the stub axles on which the wheels 15 are mounted. The bar is also supported by rods 25 adjustably hung from notched plates at the tops of the casings. A transverse bar 27 is secured at one end to the draw bar by a pivot 28 and carries a gear case 29 for a multiplying gear driven through a universal joint 53, a shaft 54, a second universal joint 55 and a splined sleeve 56 from a power take-off shaft 22 projecting from the transmission 21 of the tractor. The gear case 29 has an extension 30 including a sleeve 33 for receiving a transversely extending coupling arm 34 threaded to receive and carry pivotally a coupling yoke 38 to which the mower shoe is pivoted. The reciprocating knife 43 is driven through a pitman 45 from an eccentric wrist pin 46 on a fly-wheel 47 on the shaft of the multiplying gear. The coupling yoke 38 is also releasably connected to the tractor by a rod 57 which, at its forward end, has a lateral pin extension normally engaged in a notch in a latch plate 60 pivoted on a bracket 62 bolted to the side of the draw bar. The latch plate is normally held by springs 68 on a member 66 in such a position that the pin extension is retained in the notch, but on an obstacle being struck by the cutter bar the springs 68 yield and the rod 57 is released, permitting the complete attachment to swing backwards about the pivot 28 : the splined sleeve 56 simultaneously moves off its driving shaft, thus stopping the drive to the cutter bar. The cutter bar is rocked by a handactuated lever 76 pivoted in a bracket 70 on the bar 27 and connected by a link 74 with an upright projection 75 on the coupling yoke 38. It is lifted by a lever 89 fixed to a shaft 81 mounted in bearings in the gear case 29 and the bracket 70 and provided with a crank 84 connected to the usual lifting gear 85 - - 88 of the cutter bar. A foot lever 92 is fitted to assist the hand lever 89 and a counterbalance spring 83 is fitted to a small crank extension on the shaft 81. A guide 95 is fitted to ensure the foot lever moving clear of the tractor wheel when the mower is engaged or disengaged. A brace 97 extends across the mower attachment.
