Title: Apparatus for feeding sheets
IPC: G06K13/063
Filed: 1962-07-31
Abstract: 952,712. Feeding and stacking sheets. SPERRY RAND CORPORATION. July 31, 1962 [Sept. 11, 1961], No. 29361/62. Headings B6B and B6H. Apparatus for feeding sheets, such as cheques or record cards, on edge along a channel from an input to an output station, comprises a channel having a floor and two closely spaced vertical sides 11, 12, wherein sets of disc-like fibre brushes 15, 16, 27, 28, 34, 35 and 38, 39 extend through slots into the channel so that each disc contacts the sheet, the planes of the brushes being inclined so that each brush exerts forces on the sheet to hold it against the floor of the channel and to move it along the channel. Each brush is driven continuously by a motor, and the peripheries of opposite brushes meet on the central plane of the channel. The shafts of the first brushes 15, 16 are inclined at about forty-five degrees to the horizontal, and the shafts of the other brushes are inclined at about ten to fifteen degrees to the horizontal, so that the sheet is fed at a higher speed after leaving the brushes 15, 16. In order that each sheet may be accurately located within an encoding or imprinting device X, one of two stops 55, 56 is arranged to move into the channel, depending upon the length of the sheet. The stops are normally urged into the channel by springs, and are carried on the movable armatures 52 of solenoids 50, 51, respectively. When a sheet is placed vertically in the channel 11, 12 at the left of the brushes 15, 16, a handle is moved to select which stop 55 or 56 is to be sensed, and when just before the front edge of the sheet approaches the stop it cuts a light beam from a lamp 81 so that one of two light-sensitive cells 82, 84, one for each stop, is energized to operate the encoding device X. A unit 85, which may include a hand-operated keyboard and controls the device X, is connected to the solenoids 50, 51, and to the device X through a switch 87 which is actuated by a unit 88 connected to the photo-cells 82, 84. Delivery-apparatus.-After printing &c. by the device X, the front stop 55 or 56 is retracted by its solenoid 50 or 51, and the sheet is fed forward by the pairs of rotary brushes 34, 35 and 38, 39 to a stacking bin. The sheet, on edge, moves between the coils of a spiral stacker 44 and impinges on an inclined plate 45. The stacker spiral 44 is secured on the shaft of a disc driven continuously by frictional contact with a wheel on a motor, so that each sheet is displaced bodily in the direction E and stacked vertically on a spring-urged plate 46.

Filed: 1960-08-25
Abstract: 966,298. Automatic circuit-breakers. TEXAS INSTRUMENTS Inc. Aug. 25, 1960 [Sept. 16, 1959], No. 29424/60. Heading H2B. An automatic circuit-breaker has a bimetallic element mounted on an actuator spindle 36 and comprising a contact carrying bridging member 108 and two slotted arms 114, 116, in latching engagement with an abutment member 58 mounted on the actuator spindle 36 such that downwards movement of the spindle causes closing of the breaker contacts and the engagement of a mechanical latch comprising a spring- pressed latching ring 160 urging balls 150 into engagement with a groove 142 on spindle 36. A compression spring 64 biases the bridging member 108 towards the contacts-open position as well as providing the biasing force for the latching ring 160. Overload current through the bimetallic element causes warping of arms 114, 116, and release of the thermal latch. Spring 64 then " moves " member 108 upwardly and opens the breaker contacts while decreasing the biasing force on latching ring 160 sufficiently for a compression spring 120 to move the spindle 36 upwardly and cam balls 150 outwardly from engagement with groove 142 to release the mechanical latch. Upon cooling of the bimetallic element the arms 114, 116 re-engage abutment member 58 and button 32 is depressed manually to re-set the breaker. The contacts may be opened manually by pulling button 32 to release the mechanical latch independently of the thermal latch.

Abstract: 423,265. Springs. BARON, H., 231, Strand, London.-(Siemens & Halske Akt.- Ges.; Siemensstadt, Berlin) Oct. 24, 1933, No. 29480. [Class 108 (iii)] [See also Groups XIX and VIII] In order to equalize the driving force of the springs 44, Fig. 3, driving the carriage 42 of the punching machine or of the calculating machine, this carriage has an extension 42<a> rubbing between brakes 48 pulled towards each other by spring 50 and carried on levers 47 which are pivoted to a fixed plate 45. This extension is tapered so that the braking action on the carriage decreases as the springs de-energize in pulling the carriage to the right. In two modifications, the brakes are replaced by rollers so that spring 50 acts as an auxiliary energy accumulator. In another construction, Fig. 6, these drive-compensating parts are arranged on the spring cases 43 instead of on the carriage. Two similar cams 51<a>, 51b fixed angularly apart by 180‹ on the casing 43 coact with rollers 54<a>, 54b on levers 53<a>, 53b pivoted at 55 and pulled together at their free ends by spring 56. These rollers may be replaced by brake cheeks. In a modification of the Fig. 6 construction, spiral cams are used.

Abstract: 855,953. Electric selective-signalling systems. DIRKS, G. July 18, 1957 [Aug. 24, 1956], No. 29519/57. Divided out of 825,756. Class 40 (1). [Also in Group XVI] Apparatus which may be used for the justification of lines of type in a photo-composing machine comprises means for controlling the extent of a mechanical movement in dependence on a value represented by a train of pulses. As shown, Fig. 1, the rotation of a shaft 1 is controlled in accordance with input pulses which may indicate the widths of characters or spaces being set up in a line composing machine, which pulses are delivered over the lead 11 to a counter 8 and to the igniting electrode of a cold-cathode thyratron 9 which fires to energize the working winding of a magnetic clutch 4, a thyratron 10 cathodecoupled to the thyratron 9 being extinguished to de-energize the braking winding of the clutch 4. The shaft 5 is now driven by a motor 2 and pulses from a pulse generator 6 thereon pass to the counter 8 which counts down to its initial state whereupon an output pulse on the lead 16 fires the thyratron 10, the thyratron 9 is extinguished so that the rotation of the shaft 1 is halted. Additional pulses on a lead 17 may also be delivered to the counter 8 and may control the movement for effecting justification of a line when the pulses on the line 11 control the movement for effecting a character space or a space between two words. These two movements may also be combined by having the movements of separate shafts controlled thereby fed to a differential gear (Fig. 2, not shown). Specification 855,952 also is referred to.

Title: Improvements relating to closures for jars and like containers
IPC: B65D39/00
Filed: 1937-10-29
Abstract: 504,303. Closures for jars. CANNING TOWN GLASS WORKS, Ltd., and FRANKLIN, J. S. Oct. 29, 1937, No. 29543. [Class 125 (iii)] A closure for jars and like containers has a spigot portion which enters the container neck 1 and carries a pliable rubber band 8 to form a seal; the container mouth is flared and so forms a ridge 3 which engages the band on the sloping part 7 of the spigot between the cylindrical portions 5, 6. An air tight closure is effected by the engagement of the ridge 3 and the band 8 under light pressure because of the wedging action of the part 7. If a partial vacuum is created in the container the closure member is drawn farther into the neck 1 to effect a tighter sealing, and the rubber band is pinched between the ridge 3 and the surface 6 of the closure. The band may be retained by a bead pressed up from the bottom edge of the spigot, and the flange 9 of the closure may have portions out out to render it flexible in order to compensate for any ovality in the mouth of the container. In the modification shown in Fig. 5, the closure member 15 has a tapered portion 16 and a pliable ring 14 which acts as a seal against a concave seating 13 in the mouth of the jar 12.

Title: Discontinuity Sensing Apparatus
IPC: G06K7/10
Filed: 1966-07-01
Abstract: 1,152,355. Sensing records. INTERNATIONAL BUSINESS MACHINES CORP. 1 July, 1966 [15 July, 1965], No. 29593/66. Heading G4M. Perforations in a record card 2 are sensed by detecting reflections of a wave front launched along a card column caused by the discontinuities exhibited by the holes. In one embodiment, the sensing structure comprises a coil 9, Fig. 1, in a cylindrical cavity 17 having a gap 24 which covers a card column. The coil 9 is coupled by a matching line 14 or 27a, Fig. 2, to a one-shot generator 28 which is repetitively triggered by 200 kc./s. oscillator 30. Reflected signals are gated at 34 and applied to amplifier 40 having complementary outputs. The slight change in signal amplitude which occurs when a card 2 arrives at the sensing structure is detected at 44 to set latch 46 and trigger multivibrator 36, the latter providing shift pulses for shift register 42. Latch 46 turns off oscillator 30 and turns on 30 kc./s. oscillator 32, this frequency corresponding to the rate at which card columns pass the sensing structure. Pulses caused by reflections at holes in a card column are entered serially into shift register 42, the parallel outputs of which are fed to a decoder 80. Counter 49 has column - designating outputs. In a further embodiment, Figs. 4-6 (not shown), a negative pressure wave is launched down a tube which has holes coinciding with the index positions of a card column. The card is backed by a roller having peripheral grooves so that as the negative pressure wave front passes a card perforation, the tube is vented to atmosphere through the appropriate groove in the roller, the card perforation and the corresponding hole in the tube and a small positive pressure wave travels back along the tube to be detected by a microphone.
