Abstract: 1,233,507. Nut-runners. CHICAGO PNEUMATIC TOOL CO. 27 May, 1969 [19 July, 1968], No. 26761/69. Heading B3N. A two-speed pneumatically powered nutrunner comprises an output spindle 38, a first drive shaft 32 carrying a sun gear 33, planetary gears 35 carried by spindle 38, a second drive shaft 57 carrying a ring gear 37, a main pneumatic rotary vane motor 42 connected to drive shaft 57 for delivering high speed and low torque, and an auxiliary pneumatic rotary vane motor 11 connected to drive shaft 32 for delivering low speed and high torque. Motor 11 drives shaft 32 through planetary gears 24 and a spindle cage 26. In operation, both motors are driven simultaneously by air from a source 50 through a control valve 60, an adjustable pressure regulator 64, and passages 61 and 62. When approximately half the final tightening torque is achieved the main motor 42 stalls and holds ring gear 37 stationary, whilst auxiliary motor 11 continues to supply torque. When the final fastening torque is reached, the main motor 11 will be caused to rotate in a reverse direction since the output stall torque of an air motor is approximately half the torque required to rotate the motor backwards against the stall torque. This reversal of rotation can be used to shut off the air supply via a switch 65. The pressure in a chamber 68 controls the switch and the pressure in the chamber 68 depends on the positioning of a ball valve 76. When the rotation of shaft 52 is reversed, i.e. rotates anticlockwise, a clutch ball 85 is rolled against a wall area 92 and locks ring 79 and shaft 52 subject to the load of a plunger 82. Ring 79 is eccentrically mounted so that as it rotates it will position ball valve 76 on its seat 77. As the load builds up plunger 82 will be moved against its retaining spring and allow shaft 52 to rotate relative to the stopped ring. When the tool is next operated, clockwise rotation of shaft 52 will rotate ring 79 clockwise until shoulder 88 abuts a pin 91 and will cause clutch ball 85 to return to the position shown in Fig. 2. The pressure chamber 68 may be made common to a plurality of nut-running tools and the air flow through pipe 69 may be adjusted by a suitable feed valve 30 and a pressure regulator 70.

Abstract: 1,233,566. Service line couplings in rail vehicles. MINISTERIUM FUR VERKEHRSWESEN. 11 June, 1968, No. 27758/68. Heading B7T. An automatic central buffer coupling of a rail vehicle has a service line coupling 1 comprising a housing 5 telescopically mounted on rear part carried by a frame 16 pivoted at 15 to a support 14 rigidly mounted on the coupling head 3, the housing 5 being spring-urged forwards and engaging stops 13 on the head 3 when the buffer coupling is uncoupled, the housing 5 having centring elements 8, 9 and a projection 10, such that when the buffer coupling is coupled to a counter coupling, the housings 5, 5<SP>1</SP> are pushed back by each other until the coupling heads are fully coupled and the faces 12, 12<SP>1</SP> of the projections 10, 10<SP>1</SP> then engage and slide over each other thus moving the housings 5, 5<SP>1</SP> forwards and away from the stops 13, 13<SP>1</SP> so that the housings have freedom to accommodate lateral play of the couplings, but are centred by the elements 8, 9. A cover 18 for the ends of lines 4 is carried by a lever 19 pivoted on pin 21 on the housing 5 but spring-urged to the Fig. 5 position when the coupling head 3 is not coupled. On coupling, the housing 5 moves back until the rear of the lever 19 strikes an abutment 26 on the frame 16 when a bolt 22 moves out of indentation 28 so releasing the cover lever which pivots until its nose 25 engages behind a lever 27, which holds the nose only until coupling is complete. In another embodiment, the cover 18 is controlled by a pivoted lever actuated by the counter coupling housing 5 so as to initially move the cover lever 19 forwards so that the cover is lifted off the lines 4, and the lever 19 clears stops on the housing so that the cover 18 can swing clear of the lines 4, where it is held until the couplings are uncoupled.

Abstract: 1,251,975. Automatic fare collection machine. LONDON TRANSPORT BOARD, R. D. GILLANDERS, and S. HAINES. 31 Jan., 1969 [21 June, 1968], No. 29795/68. Heading G4T. An automatic fare collection machine for a road vehicle comprises a coin operated pushbutton fare selector 1 (Fig. 1), a driver controlled illuminated indicator panel 10 for fare and route data, a ticket printing and issuing machine responsive to signals from the fare selector, and circuitry connected to the other components of the system to produce a signal when a printed ticket is removed from slot 9. The signal controls an entry barrier or turnstile 5. The indicator panel 10 is updated by the driver at each fare stage by stepping a control knob. The driver also has a master ON/OFF switch and a bank of control switches. Coins or tokens are inserted in slot 2 and one of six fare buttons is pressed, or vice versa. A counter unit 4 counts the value of the coins and the number of passengers going through the turnstile 5 using counters 4a to 4g in Fig. 2a. On depression of a button, one contact from each of fare selection contacts 1/1 to 6/1, ticket printer contacts 1/2 to 6/2 and fare/passenger counter contacts 1/3 to 6/3 is depressed. The contacts of selector 1 are connected via matrix 14 to accumulator 15 which includes coin actuated contacts 16a, 16b, 16c. Relay A is then energized, contact A/l is closed, and relays K3 and K7 energized (contact K6/3A is closed when the turnstile is inoperative). Closure of K1/3 indicates that the fare button has been pressed and closure of K2/2 that fare selection is complete. When K4/1 is closed, relay K4 is not energized and there is no ticket in the slot 9. The energization of K7 deenergizes K3, energizes a ticket issuing solenoid ready to issue a ticket, and also energizes relay K9 and solenoid L to restore any depressed buttons. A ticket printer (not shown) includes 6 wheels for printing 6 values, 5 of which wheels are located by a detent operable by a solenoid, and the wheels are moved by solenoids LX, LB, LC, which are energized when contact K2/2 is closed. The printed ticket emerges at the slot 9 and this closes switch TU. Relays K4, K5 and K6 are energized and when the ticket is taken from the slot, contact K4/3 switches, relay K6 frees the turnstile 5 but when the passenger passes through it a microswitch de-energizes turnstile solenoid LH and relay K6. Interlocks prevent operation of the machine in the wrong sequence. If a ticket is already in the slot a fresh fare selection and coin insertion is negated as contacts K4/4 and K3/3 are open, the supply to the push-buttons is cut off and the coin slot is blocked by operation of solenoid LG and a blocking mechanism. If two buttons are pressed, microswitch PBU.INT (Fig. 2b). is closed twice momentarily instead of once if one button were pressed, and the coin acceptor unit is not actuated. When the vehicle driver changes the panel 10 to the next fare stage, relay K13 is de-energized relay K8 is energized and the printer reset to allow for the new data on the panel. A coin return slot 6 is also provided.

Abstract: 1,258,908. Feeding sheets. AGFA-GEVAERT. 20 Feb., 1969 [26 April, 1968], No. 19889/68. Heading B8R. [Also in Divisions G2-G3] Silver complex diffusion transfer processing apparatus enables the longitudinal registration between a light-sensitive sheet and a receiving sheet to be adjusted prior to the pressing of the sheets together upon removal of the sheets from the apparatus. An image-wise exposed lightsensitive sheet is fed by rollers 43, 44 to the apparatus and an, e.g., aluminium backed receiving sheet is fed by rollers 45, 46, the detection of the leading edge of each sheet by fingers 51, 50 operating micro-switches 93, 92 to de-energize magnetic clutches 68, 67 to stop the drive to the rollers. The receiving sheet is fed first to the machine. Upon detection of the leading edge of the light-sensitive sheet, clutch 68 is energized again to commence the feed of the receiving sheet and a further magnetic clutch 62 energize to transmit rotary power to time delay mechanism 63. After a preset time delay a microswitch 76 is operated which causes energization of clutch 67 to recommence feeding of the light-sensitive sheet. Both sheets are then fed in predetermined registration through an immersion treatment bath to continuously rotating rollers 47, 48 which press the sheets together to effect image transfer and deliver the sheets from the apparatus. Time delay mechanism 63 has a driven cam 72 carrying a projection to operate switch 75 so as to de-energize clutch 62 after one rotation or the cam, and a frictionally driven cam 74 carrying a projection to operate switch 76. The projection on cam 72 always comes to rest in a set position after each operation by the provision of a detent device 71, 79, and the angular orientation of cam 74 relative to cam 72 is adjustable by pressing a spring-loaded control knob in toward the apparatus and rotating the knob against a scale calibrated in the desired registration distance between the leading edges of the sheets. A motor 53 rotates all the rollers at equal peripheral speeds via the timing belts and gears shown. The sheets are fed to the apparatus from support plates which carry guides for the lateral adjustment of the sheets.
