Title: Improvements in or relating to data reading and recording apparatus
Inventor: FOLLWELL EDWARD ROGER
IPC: G06K3/00
Filed: 1962-11-01
Abstract: 1,027,400. Electric selective signalling. CREED & CO. Ltd. Oct. 25, 1963 [Nov. 1, 1962], No. 41308/62. Heading G4H. In printing (or perforating) apparatus, a series of code combinations are read, recoded and applied to a comparator which also receives code combinations derived from a drum rotating synchronously with a set of typewheels (or perforating means), to actuate the latter at the appropriate times. In the particular embodiment, 2-out-of-12 code combinations read from punched tape or cards are converted to Gray code and applied to the comparator to represent the required printed characters. In equality, the comparator produces a pulse which passes via a gate G1 (not shown) and distributer DS (not shown) to actuate the first printing hammer. The trailing edge of the pulse actuates the distributer so that the next pulse will actuate the second hammer. The pulse from the gate also actuates a stepping motor to feed the card or tape to the next character position, and momentarily closes the gate to prevent spurious signals produced during feeding from accomplishing printing.

Title: Semiconductor devices
IPC: H01L31/112
Filed: 1975-10-09
Abstract: 1481672 Semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 9 Oct 1975 [27 Dec 1974] 41385/75 Heading H1K In a charge storage semiconductor device, the charge, held in a P (or N) type region 20 and produced by means of a control electrode 30 insulated from an N (or P) type epitaxial layer 13, influences the conductivity of a channel region 32 between region 20 and a P (or N) type substrate 12, so that when appropriate voltages are applied to a P (or N) type strip 18 and to a metal strip 24, insulated from strip 18 and forming a Schottky diode 33 with region 13, the magnitude of the current flow is a measure of the conductivity of the channel region 32. The device may be used to store a video signal by having an aperture 26 in the strip 24 and by making electrode 30 transparent, thus allowing light 28 to reach the reverse biased P-N junction between regions 20 and 13, which causes a charge reduction in region 20 dependent on the intensity and duration of the illumination. Non-destructive read out is achieved by applying a forward voltage to the Schottky diode 33 via strip 24 and strip 18. An array of such devices may be fabricated as an array, Fig. 8, suitable as a substitute for a vidicon tube.

Patent GB-1016545-A (GB)
Title: Manufacture of metal-pyridine interaction products and bipyridyls
Inventor: BRADBURY FRANK RAYMOND
IPC: C07D213/22
Filed: 1961-11-23
Abstract: A metal-pyridine interaction compound is continuously produced by percolating pyridine or an alkyl pyridine, e.g. picolines or lutidines, through a reaction vessel containing a body of metal particles, e.g. Mg, Al or mixtures thereof, and withdrawing a fluid reaction mixture containing the interaction compound.  The metal particles may be in the form of turnings or powder and the reaction vessel may be maintained at 90 DEG  C.  Heated pyridine preferably dry may be supplied to the reaction vessel.  The contents of the reaction vessel may be agitated but in a zone adjacent to the point of withdrawal they are maintained in a quiescent state. Reaction initiators which induce free radical formation may be used, in particular a dispersion of Na or K in an inert diluent such as trimethylbenzene or other hydrocarbons; a halogen, e.g. Br2 or I2, or in the case of Al, a compound to break down the oxide film such as mercury compounds, e.g. HgCl2.  The excess of pyridine from the reaction may be recovered, e.g. by distillation, and returned to the reaction vessel.  An N,N-dialkylarylamine may be used as solvent for the pyridine-metal complex.  Bipyridyls may be made by oxidizing the pyridine-metal complex, e.g. using O2, air or Cl2 which may be diluted with N2, or sodium hypochlorite, nitric acid, pyridine nitrate, H2O2 or an organic nitro compound.

Title: Procedure and equipment for the automatic focussing of the charge carrier beam in devices for the working of materials by means of a charge carrier beam
IPC: B23K15/00
Filed: 1962-11-12
Abstract: 959,430. Discharge apparatus. CARL ZEISS-STIFTUNG, [trading as C. ZEISS [Firm of]]. Nov. 12, 1962 [Nov. 18, 1961], No. 42582/62. Heading H1D. [Also in Division H4] In electron/ion beam apparatus for working material, correct focusing is obtained by periodically varying the current flowing through an electromagnetic lens 13, Fig. 1, measuring the amplitude of charged-particle emission from the material 15 being worked, and setting the focusing lens current at the value corresponding to measurement of an extreme value in the charged-particle emission amplitude. As shown, the charged-particle emission is collected by interceptor 30, which may be positively biased. It is found with materials having a high electron emission and high-melting point that a gradually improving beam focus initially produces an increasing electron collection at interceptor 30 until positive ions are produced and result in a sharp minimum of the negative current collected at interceptor 30 at correct focusing. However, with materials of low electron emission and low melting point a maximum of the negative current collected at interceptor 30 indicates correct focusing. The workpiece 15 may be connected to ground through a resistance, the voltage drop in which is fed to an oscillograph, or the current collected at the workpiece may be measured to indicate chargedparticle emission therefrom. If a continuous, rather than a pulsed, electron beam is used, no clear extreme value of charged particle emission may occur, and in this case the current through lens 13 is set at the point of symmetry, or a predetermined point, between the flanks of current rise and fall at interceptor 30. If the beam focus is to be set above or below the surface of workpiece 15, then the charged particle emission current is subjected to a time delay before actuating the switch 36 which sets the lens current. In an alternative arrangement, two interceptors 45, 44, Fig. 10, are employed, one collecting electrons deflected by magnetic field 43 and the other collecting ions, the currents at 45, 44 being compared at 46 to determine the required extreme value. The current through lens 13 may oscillate about a mean value determined by the height of the surface of workpiece 15. This height is sensed by a feeler 31 associated with a potentiometer, the signal from which is subjected to a time delay in accordance with the speed at which workpiece 15 is moved across the beam path, and then rotates a potentiometer winding in lens current generator 34 to set the mean value. The sliding arm of the potentiometer is oscillated periodically by motor 35 until the latter is stopped by switch 36. Automatic focusing may be carried out only intermittently, the interceptor 30 being swivelled away from the beam path in the intervening period to avoid soiling.
