Title: Optical image sensors
IPC: H01L27/148
Filed: 1973-09-04
Abstract: 1405699 Television INTERNATIONAL BUSINESS MACHINES CORP 4 Sept 1973 [2 Nov 1972] 41516/73 Heading H4F The resolution of a multiphase CCD image detecting shift register is enhanced by storing charge in response to the light intensity sequentially under two or more of the sets of phase electrodes, the register being read out between each storage period into an auxiliary memory which is read out at the end of a complete sequence in such a way that the signals due to all the sensing sites are presented in the correct sequence. A four phase CCD image detecting register is operated by biasing the first set of phase electrodes to produce potential wells for an integration period to accumulate charge according to the illumination of the corresponding elemental areas. The normal sequence of shift pulses are then applied until the stored charges have been shifted into a first auxiliary shift register. Bias is then applied to the second set of phase electrodes for a second integration period to sample the illumination of the corresponding elemental areas and these charges are then shifted out to a second auxiliary shift register. The same procedure is applied to the third and fourth sets of phase electrodes which are read out into third and fourth auxiliary shift registers respectively. When full the four auxiliary registers hold signals corresponding to the illumination at the elemental areas defined by all the phase electrodes. The auxiliary registers are read out into latches the outputs of which are gated in turn by control signals to interleave the contents of the registers into a chronological sequence corresponding to the spatial sequence of the elemental sensing areas. The arrangement described utilizes a four phase CCD register with alternate polysilicon and metal electrodes but the invention can also be applied to three phase arrangements. The register is illuminated through the substrate but top face illumination can also be used but this restricts the charge storage to the areas below the transparent polysilicon electrodes. Instead of using four auxiliary registers a single auxiliary register clocked at four times the bit rate of the image detecting register may be used. A plurality of CCD registers may be arranged to form an image sensing matrix.

Title: Remote control means
IPC: H04B10/524
Filed: 1975-10-20
Abstract: 1517304 Selective signalling WALTER PREH GmbH 20 Oct 1975 [23 Oct 1974] 43042/75 Heading G4H [Also in Division H2] A remote control system comprises a pulse transmitter and pulse receiver, the pulse transmitter comprising a multivibrator and a plurality of frequency-determining electrical components coupled to switches which are operable to switch different ones of said components into the circuitry of the multivibrator for defining different frequencies for the transmitter, and the receiver comprises a counter for making a count in dependence upon the number of pulses received from the transmitter, and timing means for defining successively recurring counting intervals for the counter. In the transmitter, the multivibrator controls a luminescent diode via a constant-current circuit, to emit the frequency pulses as infra-red light. In the receiver, the light pulses are converted to electrical form by a photodiode and fed via filtering amplifiers and frequency dividers to the counter, the decoded counter output being gated out and the dividers and counter being reset periodically under control of the A.C. supply. Three decoder outputs are used, for respectively: (a) controlling the on/off state of a lamp, via delay, trigger and flip-flop, (b) incrementing a further counter, (c) decrementing the further counter. Actions (b) and (c) only occur if the flip-flop is in the "lamp on" state. The further counter provides an analogue voltage via a D/A converter to a comparator also receiving a ramp voltage from a ramp generator which is reset just before each zero-crossing of the A.C. supply waveform. The comparator controls switch-on of a triac supplying power to the lamp (subject to the state of the flip-flop) to control the phase angle of switch-on timing, to control brightness. A circuit ensures that on restoration of a failed A.C. supply, the flip-flop is always put into the "lamp off" state. A luminescent diode emits visible light in the vicinity of the photodiode except when light pulses are being received. Control of curtains, shutters or garage door is also possible.

Abstract: 984, 158. Thermonuclear apparatus. M. O. VALUE CO. Ltd., R. L. FERRARI, and A. REDDISH. Nov. 14, 1963 [Nov. 14, 1962], No. 43087/62. Heading G6P. A mass of ionised gas is heated during passage along a cold cathode discharge tube and may be employed in a controlled thermonuclear reaction. Hydrogen gas, which is admitted to one end of a cylindrical glass envelope and removed at a central outlet, supports a discharge of the Penning type in which a positive-ion beam passes along the tube. The beam is collimated by a magnetic field directed along the tube axis. The cathode comprises two separate ion sources so as to produce two streams of ions in the beam, one faster than the other. An interaction between the two streams is said to occur which produces an amplification of the random thermal fluctuations in both the fast and slow beams thus raising the gas temperature.

Filed: 1973-09-17
Abstract: 1448693 Impregnating wood E ARVIDSSON 17 Sept 1973 43611/73 Heading D1P Wood is impregnated by immersing the wood in impregnating liquid, subjecting the wood to a subatmospheric pressure, and subjecting the wood to a plurality of pressure waves each having a maximum intensity such that the wood is subjected, in a direction parallel or perpendicular to the fibre direction of the wood, to a pressure of -1 to -1/3, where -1 is the pressure at which crushing failure of the wood occurs and -1/3 is one third of this pressure. The pressure waves can be produced by suddenly introducing pressurised air or steam into the chamber, explosively, or by a hammer or piston. As shown in Fig. 10 wood is held under liquid by a heavy cover 26, the air evacuated and then the vacuum released to impregnate the wood with liquid.- Compressed air is then admitted via pipe 30 and a pressure wave enters the wood, re-enters the liquid at the other end of the wood, rebounds from the end wall and partition 57. The liquid is transferred to and from the treatment chamber from a storage chamber (20) containing an inflatable bag (24). An initial sub-atmospheric pressure may be produced by removing liquid through pump 45 from chamber 54, see Figs 12 and 14 (not shown). The treatment with pressure waves can be repeated. The pressure waves may be sent along the length of the wood, or normal to the wood fibre direction, simultaneously or alternatively.
