Title: Conveyor unloading appliance
Inventor: FREEMAN ALFRED
IPC: B65G47/61
Filed: 1964-12-08
Abstract: 1,133,481. Counterbalancing; conveyers. AUTOMAGIQUE (CONVEYORS) Ltd. 8 March, 1966 [8 Dec., 1964], No. 49820/64. Headings B8A and B8B. A device for lowering a load after it has been discharged from an overhead chain conveyer comprises a load receiving platform 8 supported on a buoyant piston movable downwardly in a liquid container 1 in response to loading on the platform and adapted to return upwardly due to buoyancy when the load is removed. The piston made from a flexible material is, in its upper unloaded position, a clearance fit within the cylinder 1. However, as the piston descends, the liquid pressure on the bottom surface 16<SP>1</SP> causes the same to deflect and thereby deflect the piston wall 17 outwardly to reduce the clearance with the cylinder wall 1, whereby the rate of descent is progressively reduced. In the lower position of the piston, the loading platform 8 which is pivoted to the piston-rod 6, is tilted by engagement with a stop 18 on the cylinder and the load 12 is deposited on to a shoot 19. The surface of the platform 8 is made up of rollers and a counterweight 20 is attached to the platform to level the same as it ascends. The piston 3 may be inflated to different pressures for different load ranges. In another embodiment the piston is not deformable and the clearance with the cylinder remains constant throughout. In a further embodiment, calibrated bores and valve members in the piston allow for different descent and ascent rates. In a final embodiment a fixed cam on the cylinder actuates a valve in the piston to vary the rate of movement thereof.

A system for positioning a member positions a detector relative to the member and then positions the detector and member together, compensation means receiving inputs from the two positioning means, and delivering an output to the second positioning means when appropriate. The table (1) of a lathe or drilling machine is positioned with respect to the machine bed (2) by a motor or motors (4), a detector (5) being mounted on the table (1) to sense photo-electrically the magnified image of a scale (6) fixed on the machine bed (2). The photo-electric element in the detector (5) can be moved relative to the table (1) by a motor (10) through gears (11, 9) such movement being accompanied by the production of pulses (at 12), These pulses are counted (18) and the count compared (16) with binary signals derived from the lowest two digits of the required position as set up in decimal form on dials (14). The difference output of the comparator (16) energizes the motor (10). When this difference falls to zero, the table (1) is driven, the detector (5) producing pulses which are counted (22), the count being compared (20) with binary signals derived from the other (five) decimal digits set up on the dials (14). The (difference) output of the comparator (20) drives the table motor (4) until the desired position is reached, the speed of the table (1) being reduced near the end-point. A circuit (23), controlled by the outputs of the comparators (16, 20) causes Œ1 or 0 to be added to the second counter (22) as appropriate to avoid errors. The table (1) may be driven in either direction, the counters (18, 22) being bi-directional. Gates (17, 21) controlled by the comparators (16, 20) control direction of counting.

Abstract: 1483107 Semi-conductor resistors INTERNATIONAL BUSINESS MACHINES CORP 27 Nov 1974 [26 Dec 1973] 51354/74 Heading H1K In making a high resistivity integrated circuit resistor dopant atoms are introduced by diffusion or ion implantation into a region of a semiconductor substrate preferably defined by an aperture in an oxide masking layer and lattice damage created in the region by bombardment with non-doping ions either simultaneously or in separate operations. Though the dopant atom concentration is such as would, in the absence of bombardment, give a resistivity lower than that desired the lattice damage causes it to be higher. A subsequent annealing process is conducted at such a temperature and time as to reduce the resistivity to the desired value and ensure a temperature coefficient of resistance lower than that of an unbombarded region of the same sheet resistance would have. As described the dopant atoms are of boron or phosphorus according to whether the substrate is of N or P type silicon and the non-doping ions of neon, argon, nitrogen, hydrogen, helium or preferably silicon. The ion energies and dosages and annealing conditions necessary to produce N and P type resistors with a surface resistivity of 1À8 K/square are given.

Abstract: Carbon monoxide is removed from a hydrogen containing gas such as ammonia synthesis gas by oxidation over a catalyst.  Sufficient free oxygen containing gas is added to the gas mixture (which contains 0.001-3% carbon monoxide) to give an O2:CO ratio between 0.5 and 3:1.

Title: Improvements relating to pattern recognition apparatus
IPC: G06V10/28
Filed: 1964-12-23
Abstract: 1,039,779. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1964 [Jan. 30, 1964], No. 52302/64. Heading G4R. In pattern recognition apparatus signals representing each elemental area of the pattern are combined for groups of areas to produce result signals which are combined in turn to produce pattern representing signals. The pattern is scanned by a vertical line of horizontal strokes which is repeated a number of times as the pattern passes the sensing station. The scanner 5, Fig. 1 (not shown), is controlled by a generator 11 and pulses representing the start of each horizontal stroke pass to counters 28 and 26. The former gives an output at the end of each vertical line of strokes and the latter counts three strokes comprising a group or "cell." Corresponding outputs appear on three leads in turn and a fourth output 34 indicates the end of a cell. Photo-multiplier provides input signals for video amplifier 17. After clipping the video signal is applied to integrators 36, 40 and 44. Integrator 36, which is reset at the end of a cell sums the black sensed during those three strokes. If more than a certain value is reached before the end of cell signal 34 resets the integrator, bi-stable 38 is set to produce a signal indicating that the whole cell is to be considered black. Horizontal integrator 40 is reset either by the end of cell signal or by the trailing edge of a black signal. Short horizontal black areas encountered by the horizontal stroke do not set bi-stable 43. Longer areas do set the bi-stable. Contiguous areas starting in one scan and finishing in a later scan are integrated as a single area. Circuit 23 detects vertically placed areas, that is black areas of a given minimum length in each of the three strokes of the cell. The output of integrator 44 is applied by three And gates 48-50, one enabled in each stroke, to corresponding bi-stable circuits 57, 55, 51. If all become set And gate 53 gives an output. The three outputs obtained are each stored on a delay line in the form of a shift-register. Certain stages of the shift registers are gated together in selected combinations so that a cell shall be considered black if certain conditions prevail in that cell and in those above and below it or to one side of it. Examples of possible combinations are given.
