Title: Improvements in and relating to numerically controlled automatic electric positioning systems
IPC: G05B19/23
Filed: 1960-12-13
Abstract: 980,851. Numerical control of machine tools. D. SCIAKY. Dec. 13,1960 [Dec.24, 1959], No. 42796/60. Heading G3N. [Also in Divisions G4 and H2] The worktable of a drilling machine is moved from point to point by electric motor driven leadscrews which carry apertured discs so that rotation of the leadscrews produce incremented pulses from photo-cells. These pulses are counted until they approach a number pre-selected either manually or by a binary coded punched tape when the speed of the leadscrew is reduced. The counting is completed on an auxiliary counter and the motor is then stopped. The work-table 10, is movable in two directions at right-angles by leadscrews 11, 12 driven by motors 15, 75 through clutches 16, 76. Considering only the control of leadscrew 11, as the other is identical, a disc 17 with two rows of apertures, is secured to the leadscrew and controls a pair of photo-cells 21, 22 and the two valves 24, 25 of a multivibrator so that an outer aperture switches the multivibrator to produce a pulse and the inner aperture which follows, resets it. The pulses may alternatively be generated electro-magnetically. The pulses are applied to a main counter consisting of five cold-cathode counter tubes 35, 36, 37, 38, 39 which, with transfer networks, count units, tens, hundreds &c. The cathodes of each counter tube can be selectively connected to an undisclosed coincidence circuit 50 which produces an output when the selected count has been reached. The selection can be made either manually, or Fig. 6 (not shown) by diode gating networks-one network per tube-each controlled by four change-over switches. The switches are actuated by a punched tape 34 having 5 decimal ranks each in standard four digit binary code. The motor 15 runs at full speed, energized by a control 59 because a thyratron 56 has been fired by a sequence circuit 52. An output from the coincidence circuit momentarily cuts off a valve 58 which extinguishes thyratron 56 and fire a thyratron 57. This causes the control 59 to run the motor slowly. The change of grid voltage when thyratron 56 is extinguished opens a gate 31 to admit pulses from the multivibrator 24, 25 to an auxiliary counter consisting of 3 cold-cathode counter tubes 65, 66. 69. This is always reset to a pre-determined number. When the auxiliary counter has counted back to zero an output signal is applied to momentarily cut off valve 58, which extinguishes thyratron 57 and fires a thyratron 55 to disengage clutch 16 through a control 72. A circuit 52 now causes the drilling operation to be carried out, the tape recorder head 53 to be lifted out of contact with the tape, the punched tape 34 to move on, and the reader head to re-engage the tape. Completion of the drilling operation is said to cause the next positioning cycle to commence

Filed: 1962-11-13
Abstract: 947,995. Electric cut-outs. FEDERAL PACIFIC ELECTRIC CO. Nov. 13, 1962, No. 42913/62. Heading H2G. A cartridge fuse comprises a fuse link 14 (Fig. 1), of relatively high melting temperature, held within a tube of insulating material 12 by two brass (or similar metal) end caps 10, 11, the link having an aperture 20 filled by an annular body of metal 22 of low-melting temperature and one or more regions of reduced cross-section 16, 18 (Fig. 2, not shown), which may be constituted by apertures, spaced from the aperture 20 along the link. The link may be of silver or copper and the annular body 22 of solder, being either an apertured filling of metal alloyed to the link around the edge of the aperture 20, or a hollow rivet secured mechanically in the link. Aperture 18 may also be filled with solder and extra apertures may be provided between member 20 and the end caps. The tube 12 may be filled with sand. Prolonged overcurrent causes localized high temperature regions at 16, 18 and 20; heat flow from the region 18 accentuates the heating at 20. The annular solder body then begins to melt and spreads laterally mainly towards 18 (Fig. 5), reducing the cross-section at 20, the formation of a menicus film being prevented by the annular shape. Continued overcurrent causes further increase in the hole in the solder body, the resistivity of the adjacent part of the link increases, owing to the further alloying with the solder, and the fuse link quickly ruptures at 20.

Patent GB-433448-A (GB)
Abstract: 433,448. Ticket issuing machines. BELL PUNCH CO., Ltd., 39, St. James's Street, Westminster. Sept. 5, 1934, No. 18809/35. Divided out of 431,338 and addition to 426,326. [Class 106 (iii)] In ticket-issuing machines as described in the parent Specification wherein means are provided for feeding and simultaneously printing, during each ticket-issuing cycle, a predetermined length of ticket strip, the severing mechanism, which cuts-off the strip at the point of tangency of the feeding and printing rollers, is formed as a separate entity, and means are provided for automatically reciprocating the fed strip relatively to the fixed severing mechanism in order correctly to position the strip for the operations. The feed surfaces of a combined printing and feed roller 2 comprise an arc of printing type 8 and a pair of type rollers, 10. On depressing a key 18, a motor-driven shaft drives through gearing the roller 2 one complete revolution. A cam operated block 57 carrying oppositing-acting uni-directional clutch levers 58, 59 is used to grip and move the strip away from from the fixed guillotine plate 43 located close to the delivery gate 4. A cam member 66 engages and frees the clutch lever 58 near the end of the lowering movement so as to release the strip which, as the roller 2 continues to rotate, is simultaneously printed and fed forward and on termination of the printing phase the clutch block 57 is operated to move the strip forward to the desired position in the guillotine, which is then operated. A tool is described to enable the strip to be initially threaded into position past the clutch levers 58, 59. If the ticket-forming strip is partially pre-printed, the feed roller 2 may be formed with peripheral feeding surfaces in addition to those constituted by the surface of the printing type. As described in the parent Specification, means may be provided for automatically adjusting the position of the fed ticket length in relation to the severing knife. Specification 431,338 is referred to.

Abstract: 1,142,831. Hearing aids. BERNATONE Ltd. 11 Sept., 1967 [3 Oct., 1966], No. 44100/66. Heading H4J. An in-the-ear hearing aid has a cavity through which sounds from the earphone to the acoustic meatus of the wearer are passed. The cavity provides an acoustic loading for the earphone reducing distortion and allowing increased gain. As shown the aid is enclosed in a shell 10 conforming to the general shape of the external ear. The shell has a microphone cavity 16, a battery cavity 14, and a cavity 18, 20, 22 for receiving the amplifier volume control and earphone. The output of the earphone is coupled to the meatus of the wearer through apertures 28 and 30 via a cavity 26. This cavity which has a volume of about 0À25 c.c. provides the acoustic loading. Filtering material e.g. foamed plastic or cotton wool may be introduced in the cavity. The aperture 30 is threaded to receive a thimble shaped tip (32, Fig. 2, not shown) which extends into the meatus of the wearer and is of a diameter such as to provide a good acoustic seal in the meatus and prevent feedback. The tip may be removed and either cleaned or thrown away if the aperture through it becomes blocked with wax. The filter material prevents wax reaching the earphone.

Filed: 1974-10-11
Abstract: 1482791 Particle analyzers COULTER ELECTRONICS Ltd 11 Oct 1974 [16 Oct 1973] 44133/74 Heading G1N [Also in Division H3]  A pulse discriminator in a Coulter particle analyzer, accepts pulses within upper and lower threshold levels and outputs rectangular pulses of uniform duration, with an amplitude corresponding to the input. The circuit is useful for distinguishing platelets from red blood cells (which give larger pulses). PROCESSING ACCEPTABLE PULSES. The pulse from scanner 10 passes electronic-input-switch 16 and is applied to the lower and upper level comparators 20, 22, and a sample/hold circuit. As the pulse passes trailing-edge-detector 30 triggers univibrator 32 to open switch 42 passing the "heldvalue" to the analyzer circuit 44. While a value is held, output 64, from the sampler 24, operates bi-stable 54 to switch off the input at 16. Resetting. When the output-switching-pulse from univibrator 32 ceases trailing-edge-detector 46 provides a resetting pulse (i) on line 48, to bi-stable 54 to switch on the input at 16 to receive the next pulse (ii) on line 49 to clear the holding circuit (iii) on line 51 to reset bi-stable 38 if necessary. REJECTING LARGE PULSES. If the scanner pulse is of sufficient amplitude to pass the upper level comparator 22 (in addition to the lower level 20), it triggers bi-stable 38 to inhibit and gate 36 so that switch 42 is not operated by the univibrator 32. The circuit is then reset as before.

Filed: 1971-09-23
Abstract: 1370453 Multi coloured spacially filtered photographic records EASTMAN KODAK CO 23 Sept 1971 [25 Sept 1970 (2)] 44347/71 Heading G2J Two or more colour images are recorded on a photographic material having portions separately sensitive to the colours by exposing each sensitive portion to a diffraction grating pattern having a higher spatial frequency than the finest image detail to be recorded, and previously or subsequently exposing each sensitive portion to an image containing the colours. Thus a conventional three-layer colour film can be exposed successively to blue, green and red light through gratings which differ in alignment or spatial frequency, then exposed to a scene, processed to yield a colour negative or positive and viewed or printed by white light in a spatial filtering system in which the first order spectra produced by the gratings are separated. Alternatively there may be used a single-layer film having a mixture of grains separately sensitive to blue, green and red light. The spatial filtering system should be designed to pass the first order spectra and block the zero and higher order spectra, or vice versa. The Specification also describes an analogous system (not claimed) in which the three images are formed on separate frames of a panchromatic film and then superimposed on one another.
