Title: Record document feeding arrangement
IPC: B65H1/18
Filed: 1961-06-22
Abstract: 916,451. Feeding sheets. NATIONAL CASH REGISTER CO. June 22, 1961 [July 18, 1960], No. 22652/61. Class 100 (1). In apparatus for separating record documents, e.g. cards, from the top of a pile, the pile is supported by a table which is raised to place the top card adjacent the separator by mechanism controlled by a radiation-sensitive device which is disposed to receive radiation from an electromagnetic source and reflected from the top card. Pile tables.-The pile-raising mechanism is substantially as described in Specification 867,293, and comprises a table 60, supporting a pile of record cards 33, guided for vertical movement in tracks 65 and having racks 67 in mesh with driving gears 69 on a shaft 70. The shaft 70 is driven from a shaft 74 by a ratchet-wheel 75 and gears 72, 73, and the wheel 75 is driven by a pawl 77 on a plate 76 which is oscillated about the shaft 74 by a pitman 97. The pitman 97 is constantly oscillated by a motor, pulley 85, gears 89-92, and a cam 95 on a shaft 94, but a full stroke to the left (Fig. 1) is only permitted when a stop 100 thereon is opposite a shoulder 102 in a pivoted arm 104; when a second shoulder 101 is opposite the stop 100, due to the raising of the arm 104, the pitman 97 is not moved substantially to the left, and the pawl 77 cannot therefore move the ratchet-wheel 75 to raise the table 60. The arm 104 is secured to a shaft 105 which can be rocked, to control the position of the shoulders 101, 102 on the arm, by a solenoid (L104, not shown). This solenoid is in a circuit which includes a photo-cell 174, Fig. 4, a thyratron valve, and a relay, whereby radiation from two lamps 171 reflected by the top card 33 into the cell 174 will cause the solenoid to remain energized, and the table 60 will be raised. If, however, light is cut off from the cell 174, the solenoid is de-energized, the arm 104 is raised to prevent movement of the pitman 97 to the left, and the table 60 is not raised. The lamps 171 are mounted on one side of a suction cylinder 134 which separates the cards 33, and the photo-cell 174 is mounted in a tube 173 at the opposite side of the cylinder, such that, when the top card is closer than about oneeighth of an inch to the cylinder, no light can be reflected by the card on to the cell 174. A shield 172 prevents stray illumination falling on the top card 33. Separators.-The cards 33 are separated sequentially from the top of the pile by a rotary suction cylinder 134, and separation is assisted by air-blasts from nozzles 131, 132, substantially as described in Specification 867,293.

Title: Improvements in and relating to seals for rotary shafts and the like
Inventor: MILLER ALBERT ARTHUR
IPC: F16J15/40
Filed: 1951-09-28
Abstract: 705,099. Stuffing-box substitutes. SELFCHANGING GEARS, Ltd. Sept. 17, 1952 [Sept. 28, 1951], No. 22718/51. Class 122 (5) A rotary shaft oil seal comprises a circumferential helical groove or like formation arranged on one or both of a pair of closely spaced relatively rotatable surfaces to return oil in the direction of leakage, in combination with two engaged faces in rubbing sealing contact which faces are separated by centrifugal means when the shaft rotates at and above a predetermined speed. A rotary sleeve 1. closely surrounded by a stationary sleeve 3 having a helical groove 4 on its inner peripheral surface, is mounted on a flexible metal disc 7 and urged thereby into rubbing sealing contact with an inturned flange 6 of the sleeve 3. The disc 7 is gripped between two rings 9, 10 on a bearing shaft 2 and the outer ring 10 has a recess 11 therein housing balls 12 and having an inwardly tapered or curved wall 14 which, when the balls are thrown outwardly by centrifugal force deflects them axially into contact with the disc 7 and, at a predetermined speed, the rubbing faces of the sleeves 1 and 3 are separated. At and above that speed sealing is effected by the helical groove 4. In a modification the disc 7 is loaded by a plate spring and the balls 12 are mounted in a recess in a ring, on the bearing side of the disc and arranged to engage an inclined annular surface on the rotary sleeve 1 to thereby withdraw it, at a predetermined speed, from rubbing contact with the stationary sleeve 3. In a further modification the balls 12 are replaced by weights attached to, or integral with, a slotted ring adjacent the disc 7, the weights being offset from the plane of the ring, so that under centrifugal force they bend the outer portions of the slotted ring and thereby axially displace the disc 7 and the sleeve 1.

Title: Improvements in or relating to combined electric switches and electric couplings
IPC: H01R13/707
Filed: 1925-09-14
Abstract: 246,403. Crabtree, J. A. Sept. 14, 1925. Plug couplings combined with switches. In a switch-coupling of the type in which a plunger or slide locks the switch in the open position when the plug is withdrawn, an obstruction is arranged to prevent displacement of the plunger by means other than the plug. In the form shown in Fig. 1, a slide b coupled to the arm of a tumbler switch a, is slotted and notched as shown in Fig. G, so that the earthing pin d of the plug can be inserted into the socket e only when the switch is open, and a spring-pressed plunger k sliding on a pin l normally occupies the notch and locks the switch; the pin d which is then longer than the others is made hollow so as to pass over the obstructing pin l, and is grooved at o so as to permit the necessary movement of the slide b for the closing of the switch, at the same time locking the plug in position till the switch is opened. The socket e is positioned by a plate f which forms a guide for the slide b, and is connected to the bridge i of the switch and an earthing terminal. In a modification a bar is fixed across the mouth of the socket e, and the pin d is correspondingly slotted. Specification 248,496 is referred to.
