Title: Improvements in sheet feed mechanism
IPC: B65H11/00
Filed: 1929-04-08
Abstract: 325,158. Ehrig, H., and Keilhauer, U. April 8, 1929. Sheet-guides and feed-tables. - A sheet-feed table a for printing and like machines is constructed with a grid of guide bars h arranged above the feed surface of the table, and on the bars hare slidably mounted holders m in which are mounted levers s supporting rollers i which rest on the sheets and may be inclined to the direction of feed, as shown in Fig. 6, for flattening out sheets which are buckled or creased. To prevent obstruction of the sheets due to the front edges of the sheets striking the holders m, the holders m are arranged with under-cut channels which can slide on the upper portions of the bars h, and the under surfaces of the bars h are substantially below the under surfaces of the holders. The bars h may be of the form shown in Figs. 3, 4 and 5. The bars h are arranged in series lengthwise of the table, and are supported by transverse bars g to which the bars are connected by brackets k bridging the gaps between successive bars. To enable the inclination of the rollers i to be varied relatively to the direction of feed, the channels in the holders m may be formed wider than the bars h, as shown in Fig. 6, and by means of a rib n and two screws p the inclination of a holder m to its bar h may be varied.

Title: Coin-freed mechanism for use with petrol pumps
IPC: G07F13/02
Filed: 1960-03-29
Abstract: 940, 203. Coin freed petrol pumps. A. B. GREEN. March 22, 1961 [March 29, 1960], No. 11033/60. Heading G4V. Coin freeing mechanism for a petrol pump comprises a gear train 7 within a casing 1, a rotatable hand wheel which is located outside the casing and is not in engagement with the gear train when the mechanism is inoperative, a coin slot 2 so formed in the casing that the insertion of a coin of predetermined type causes the hand wheel operatively to engage the gear train whereby subsequent rotation of the hand wheel is transmitted to the gear train, and a cam 10 associated with the gear train permits or causes operation of a switch 11 for the pump motor. A coin inserted through the slot 2 into a coin drum moves the first gear 8 of the train 7 axially against spring-loading into mesh with the second gear 9 and, on turning a shaft 12 by the exterior hand wheel, the gear train is rotated. A cam 4 carries the coin around until it falls into a container 5 by way of a shoot 6, a pawl- and-ratchet 14 preventing reverse rotation. The cam 10 may operate the switch 11 after one revolution or may rotate at half the speed of the gear 8 the first half revolution then operating a lever 31 to prevent operation of the switch 11 and the completion of the revolution, after the insertion of a second coin, returning the lever to its original position to allow operation of the switch. During rotation of the gear train, another cam 22 pivots an arm 20 so that a slide 18 unmasks tubes 17 for the delivery of change to a compartment 32. The last gear 23 of the train meshes with a gear 24 and a ratchet-and-pawl 25 is mounted on a spring-loaded shaft 26 connected to the pump motor. To provide for operation of the pump without the use of the coin mechanism, the shaft 26 is axially movable to move the gear 24 out of mesh with the gear 23 and can be held in either of its two positions by a catch 29 engaging in one of two grooves 27, 28; a similar spring-loaded and grooved shaft and a catch prevent operation of the switch 11. To provide also for the sale of more expensive petrol, a second coin slot is provided for coins which cause engagement of a dog clutch between the gear 8 and the hand wheel on the shaft 12. A magnetic plunger device 30 is drawn into engagement with a coin of incorrect composition and prevents it from entering the slot 2.

Abstract: 1476326 Brazing COMMISSARIAT A L' ENERGIE ATOMIQUE 12 March 1974 [27 April 1973] 11046/74 Heading B3R In a method of joining two metal parts made of metals (e.g. Ni, Ni alloy, Ni-P alloy, Co) capable of forming aluminides, aluminium is applied between the surfaces of the metal parts to be connected so as to form a fixing zone between the two parts and this zone is then heated to a temperature of between 550 and 700‹ C. so is to effect the formation of the aluminides. The two parts may comprise a metal spigot and a porous metal tube of the type used for isotope separation, the metal being for example nickel or a nickel alloy. The aluminium may be an aluminium foil and applied to the outer surface of the spigot before it is fitted into the porous tube. In a particular example, the spigot was of Ni alloy and the porous tube of pure Ni, and after positioning the assembly was heated to 600‹ C. for 1 min. in an argon atmosphere containing 10 wt. per cent H 2 . During this heat treatment, the Al reacted exothermically with the Ni at 600‹ C. and melted at 650‹ C. Locally the reaction products were very hard and mechanically strong nickel aluminides, NiAl 3 , NiAl or Ni 3 Al, which diffuse with the adjacent Ni and Ni alloy. Alternatively, the Al may be deposited by plasma or flame torch spraying or applied in the form of a paint comprising Al powder, a suspension liquid and a thermallyremovable organic binder. The heating, preferably induction heating, is carried out in a furnace in a reducing or neutral atmosphere.

Title: Improvements in or relating to reverse locking mechanisms or overrunning clutches
IPC: B60T7/12
Filed: 1937-04-20
Abstract: 477,746. Locking vehicle wheels. CIRAC AUTOMATIC REVERSE CONTROL CO. April 20, 1937, No. 11274. Convention date, Sept. 16, 1936. [Class 103 (i)] In a mechanism for preventing backward movement of the wheels of a motor-vehicle of the kind comprising pivoted spring-controlled pawls 18 coacting with a ratchet wheel 19 keyed to the drive shaft 14, the pawls 18 during the normal running of the vehicle are held out of active position by means of a pair of cam plates 41, Fig. 4, which are frictionally engaged with the ratchet wheel 19 but are capable of oscillating through a limited arc only, and are so disposed that in their extreme forward position surfaces 49 on the plates engage and lift teeth 20 on the pawls 18 out of adjacent notches 47 on the plates 41. At the opposite side of each notch 47 is formed a shallow step or shoulder 48 on which the tooth 20 will come to rest when the vehicle has been driven backwards and the cam plates have been carried to their extreme rearward position. In addition, in order to displace the pawls 18 to an inoperative position at the same time as the gear is placed in reverse a second control plate 25 having a cam surface co-operating with a roller 23 on the pawl 18 is adapted to be swung through the necessary arc. Such displacement is effected by forming on the plate 25 an arm 27 with inclined surface 37, Fig. 3, which is engaged by a wedge 36 on the end of a rod 35 linked with the gear lever. A bell-crank lever 38 may also engage the arm 27 for manual operation of the control plate 25 whenever this is desired. The oscillating movement of the cam plates 41 is limited by means of lugs 44 on the plates abutting in one direction against shoulders 46 on the casing 11 and in the other direction against the hubs of the pawls 18. After the gear has been placed in reverse and the vehicle brought to rest, the gear lever may be moved to neutral or other position, for the lugs 44 will be in contact with the shoulders 46 and the teeth 20 will be resting on the steps 48 ; subsequently a very slight forward movement will allow the pawls to drop into effective position, from which again they will be removed by the cam plates 41 when the vehicle is driven forwardly.

Abstract: 765.451. Rotary printing - mahines. WARNER - JONES & CO., Ltd., K. Aug. 3, 1951 [May 8, 1950], No. 11366/50. Class 100(2) Tripping arrangements. In a rotary printing-machine, means for tripping one of the cylinders is controlled by a sheetoperated detector, and comprises a shaft 1 carrying, e.g. an eccentric for throwing the cylinder off and on, a lever 3 fixed to the shaft a cam-operated lever 2 for moving the lever 3 to the "on" or printing position through a driving pawl 4, a pawl 6 for retaining the lever 3 in the printing position, and a lever 9 to trip the driving pawl 4: the detector causes the pawls 4, 6 to become operative or to be tripped according to whether a sheet is present or not. The lever 2. which is freely pivoted on the shaft 1 is spring-urged against a continuously-rotating cam 15 and has the pawl 4 pivoted thereto. The pawl 4 engages a tooth 5 on the lever 3 as the lever 2 moves to the right to throw-on the impression but can be tripped during the leftward movement by the engagement of a tail 40 thereof with a pin 11 on the trip lever 9 so that on the next rightward movement it rides over the tooth 5. The lever 9 and the pawl 6 are freely pivoted about a fixed axis 7 and are interconnected by a pin 12 on the pawl engaging a slot 14 in the lever a light spring 10 normally holding the pin against the left-hand end of the slot. The pawl 6 engages a tooth 8 in the lever 3 to retain the lever in the printing position as shown. If the absence of a sheet is detected, an impulse is given whereby the pawl 6 is urged downwardly but the pressure of the tooth prevents the pawl 6 dropping until the high part of the cam 15 causes the pawl 4 to engage the tooth 5 and release the pressure, whereupon the lever 3 can move leftward to non-printing position. The trip lever 9 moves to the right as the pawl 6 drops and the pin 11 engages the tail 40 on the leftward movement of the levers 2. 3 so that the pawl 4 is tripped. When the presence of a sheet is next detected, an impulse is given whereby the pawl 6 is urged upwardly. The pin 11 then moves to the left and the pawl 4 engages the tooth 5 to move the lever 3 to the printing position. As this position is reached, the pawl 6 engages the tooth 8 to retain the lever 3. The detecting mechanism may be as described in Specification 732,670 or any known mechanical, electrical or pneumatic type.
