Abstract: 1,081,837. Printing apparatus. SPERRY RAND CORPORATION. April 18, 1966 [April 29, 1965], No. 16941/66. Heading G4H. A punched tape 2 is advanced through a read station 30 by an amount corresponding to a predetermined number of characters, e.g. 8, the characters being entered in a shift register 42, and a group of eight characters is then printed. Advancement of the tape 2 may be under the control of punching apparatus which causes gate 88 to be enabled after 8 characters have been punched, the second input to gate 88 being provided when a previous print cycle has been completed. After a preset delay at 96 to allow the tape 2 to become stabilized after advancement, a counter 126 is reset and a comparator disable signal 98 is removed to start a print cycle. Counters 76 and 126 are stepped by the sensing of clock marks 70 on print drum 54, counter 76 being synchronized with drum 54 by means of mark 71. Each coded output from counter 76 is compared at 50 with the characters stored in stages 1-8 of shift register 42 and hammers 68 are actuated to print the 8 characters in cyclic character order, though the origin of the cycle is variable as determined by the instant at which counter 126 is reset. At the end of a complete print cycle, gate 86 disables the comparator 42 and may initiate advancement of the tape.

Title: Improvements in or relating to circuit arrangements for measuring electric charges applied to a condenser
IPC: G01R1/30
Filed: 1952-07-07
Abstract: 708,891. Measuring charge of condensers. LUFTTECHNISCHE GES. July 7, 1952 [July 6, 1951], No. 17094/52. Class 37. Charges applied to a measuring condenser are used to excite an oscillation circuit, the oscillation produced being amplified and its amplitude measured. The charges to be measured are applied to a condenser 1 which on closing a switch 2 is connected to an inductance 3 to form an oscillation circuit. The oscillations produced are fed to the grid of an amplifier valve 4 followed, if necessary, by further amplifier valves. An additional condenser 5 of high capacitance may be connected in parallel with the condenser i on closure of the switch 2 to reduce rebound phenomena. The circuits. I, II of the individual resonance amplifier stages are tuned to a frequency approximately midway between the frequencies produced by the condenser 1 alone and by the condensers 1, 5 in parallel in the oscillation circuit. For measurement of a non- recurring charge the measuring instrument may be provided with means for holding its indication, as by the use of a condenser of high capacitance to which the amplified oscillation is applied after rectification.

Patent GB-796407-A (GB)
Title: Method of producing single semiconductor crystals
IPC: C30B17/00
Filed: 1954-06-14
Abstract: Small single crystals of germanium are formed by heating germanium or germanium dioxide to produce small molten specimens each containing germanium in an amount equal to that desired in a diode or transistor crystal, and cooling the molten specimens at a rate between 0.3 DEG C. and 2000 DEG  C. per second to <PICT:0796407/III/1> <PICT:0796407/III/2> <PICT:0796407/III/3> obtain single crystals.  In one method specimens 9 (Fig. 1) of germanium or germanium dioxide are placed on a plate 10, which may be of quartz or graphite and may be coated with carbon black, in a quartz tube 13 surrounded by a heating coil 14.  The heating coil may be moved longitudinally so that the specimens are melted and then cooled, or the coil may be stationary and the plate 10 moved along the tube 13.  A gas such as hydrogen, nitrogen, helium or argon may be passed through the tube 13 by means of an inlet 16 and an outlet 18.  The plate 10 may be flat or may have recesses for locating the specimens, or may have grooves narrower than the specimens so that the specimens are supported by the upper edges of the grooves.  Junctions may be obtained by adding donor or acceptor inpurities to the specimens, or by heating and cooling the specimens with a vacuum in the tube 13 and then adding impurities by metal evaporation or by admitting gaseous metal compounds.  In another method discrete germanium specimens are embedded in a mass of carbon black which is heated and cooled, or a specimen 40 (Fig. 4) is placed in a quartz mould 42 having a cover 43 in a furnace 41, the single crystal being formed as a thin slab as the cover flattens the specimen when it melts.  In a further method germanium 58 (Fig. 5) is melted in a chamber 56 having a bore 57 by a heater coil 59 surrounding a quartz tube 50. Drops of molten germanium pass through the bore 57 and form single crystals as they fall, which are received in a liquid bath 51.  Gas is passed through the tube 50 by means of inlets 60 and outlet 61 to provide a suitable atmosphere and to delay the descent of the drops.

Title: Range finding system
IPC: G02B7/32
Filed: 1971-05-27
Abstract: 1354030 Automatic focusing CANON KK 27 May 1971 [27 May 1970 (3)] 17580/71 Heading H4D In an automatic focusing system, based on triangulation principles and in which a lightbeam is directed on to the object to be focused and the light reflected therefrom directed on to a photodetector in a position thereon indicative of the object's range, the optical means directing the reflected light is such that the reflected light range formed on the detector has an elongated shape. This is stated to improve the sensitivity of the system. In Fig. 1, a spherical or parabolic mirror 2 directs light from a bulb 1, incorporating a condenser 3, on to the object via colour or I.R. filter 4. The reflected light, after filtering at 7 is formed into a flat beam by cylindrical lens 8 and as such is directed by fixed mirror 9 and mirror 10, coupled to a focusing lens 13, on to differential photodetectors 11a, 11b. The differential output of the detectors is used to energize focusing motor 17 and adjust lens 13 until mirror 10 directs the line image on to the abutting line C between the detectors. To help in identifying the reflected light, the transmitted beam may be chopped and the differential detector outputs fed to two synchronous detectors (one via a phase inverter), the chopper actuating signal being used as the synchronous detector's reference whereby only one of the synchronous detectors gives an output dependent on the sense of the out of focus. The outputs of the two photodetectors may be summed, or a separate photodetector used to give a signal indicative of the intensity of the reflected light and produce a corresponding correction to the brightness of the source. If the brightness falls, indicating that the object is near infinity the motor is energized to move the lens to infinity focusing. In a concentric arrangement, Fig. 4, the reflected light is reflected by spherical reflector 18 on to axially movable photodetector pairs 11a, 11b, via optical wedges 19 forming the elongated images. Only one photodetector is necessary, Fig. 6, if a triangular mask 20, Fig. 8, is placed in front of it and the upper and lower reflected beams from cylindrical lenses 8a, 8b alternately applied thereto by means of shutter 24. To assist in the formation of the elongated image, the transmitted beam may be flat, using a linear filament bulb with no condenser, Fig. 10 (not shown), or a slit mask in front of the bulb.
