Title: Photosensitive detecotrs
IPC: H04N5/369
Filed: 1970-08-24
Abstract: 1345698 Photo-sensitive array circuit INTEGRATED PHOTOMATRIX Ltd 12 Oct 1971 40611/70 Heading G1A In a photo-sensitive array circuit, for detecting local variations in brightness, comprising an array of sub-circuits connected in parallel, each sub-circuit comprises a photo-diode 11, a MOST M1 (Metal oxide silicon transistor) which acts as a gate and a further MOST M2 which acts as an amplifier, the elements being connected to supply rails 12 and 13 and to a negative pulse input rail 15 and an output rail 14 as shown in Fig.1. This sub-circuit is repeated Fig. 2 (not shown) to form the desired array and the circuit is preferably of integrated circuit form. In operation a series of negative (See top waveform Fig.3) are applied to the terminal of rail 15. Each negative pulse recharges all the photodiodes via each MOST M1, to a predetermined reverse bias voltage and, on removing the pulse, the potential on each diode rises independently of the other diodes in the array as charge is lost via reverse bias leakage current (See bottom waveform Fig.3), each amplifying MOST M2 isolating each photo-diode. The rate of discharge depending upon the degree of illumination of the photo-diode concerned. All the outputs of the amplifying MOST's are fed to the output rail 14 which has a resistance R1 Fig. 2 (not shown) connected between it and earth and the final output potential appearing across R1 is determined by the diode which has undergone the least illumination. In a further embodiment Fig. 4 (not shown) the input and output rails are combined. In another embodiment Fig. 6 (not shown) an additional photo-sensitive element is added to the array of circuits, and it is connected in a circuit similar to Fig.1. The additional photosensitive element is physically located in the array of photo-diodes Fig. 7 (not shown) so as to provide an output representative of the mean illumination of the photo-diodes and this output may then be compared with the main output from the diodes 11.

IPC: H02P1/28
Filed: 1971-05-18
Abstract: 1353652 Control of AC motors COAL INDUSTRY (PATENTS) Ltd 5 May 1972 [18 May 1971] 15542/71 Heading H2J To ensure that a warning is given when a three-phase dynamo-electric machine having windings 2, energized by supply lines 4, 5, 6, is to be started, initially only lines 5, 6 are energized by closing auxiliary contactors 10. The current in line 6 passes through a warning device 23, e.g. a siren, satisfactory operation of which opens a switch 25, operated centrifugally or by air pressure or suction, so that the current in line 6 is rectified by a diode 24. The direct current is detected by relay 15 which in conjunction with a timing device (not shown) closes main contactors 9, thus energizing all three supply lines to the machine. The currents flowing in lines 4 and 5, which pass through windings 16, 17 of a transformer 18, energize coil 19 and solenoid 20 which closes contact 21, thus short-circuiting the siren which is rendered inoperative. The warning device 23 may additionally or alternatively give a visual signal. The machine may be in a coal mine, operated from a remote position. In a second embodiment (Fig. 2, not shown) the diode 24 is omitted and relay 15 is replaced by two current-sensitive relays (26, 27) which check the satisfactory operation of the warning- device and actuate the main contactors 9.

Title: Derailment detector for railway vehicles
IPC: B60T7/12
Filed: 1996-03-26
Abstract: The detector (3) has a release mechanism in a housing which can bleed the brake in the case of a derailment of the brake's air conduit (25). The detector is combined with an emergency brake (1) in the form of an emergency brake block (5).

Title: Laryngeal mask with large-bore gastric drainage
IPC: A61M25/04
Filed: 2002-03-19
Abstract: An artificial airway device for use in unconscious patients comprises a laryngo-pharyngeal mask including an expandable masking ring. The expandable mask sealingly surrounds the laryngeal inlet when expanded to obstruct communication between the laryngeal inlet and oesophagus. One or more airway tubes connected to the mask provide for fluid flow to a portion of the mask facing the laryngeal inlet when said mask sealingly surrounds the laryngeal inlet. A gastro-tube connected to the mask provides a fluid flow-path to the mask when the mask sealingly surrounds the laryngeal inlet. The distal end of the gastro tube passes through the masking ring at its narrower distal region where, when installed in a patient, it abuts against the oesophagus; and the distal portion of the gastro-tube flattens when the mask is deflated to facilitate smooth passage behind the larynx during insertion through the mouth and throat of the patient.

Title: Process for resurfacing a monocrystalline or directionally solidified piece
IPC: C30B29/52
Filed: 2005-08-30
Abstract: The recharging of a metal component, that is monocrystalline or has a directed solidification with a thickness (W s) of less than 2 mm, consists of applying a laser beam and a flux of metal powder, with the same nature as the metal component, on the component in order to fabricate at least one layer of metal.

The laser beam and the flux of powder are applied in a coaxial manner on the component and the ratio of the power to the speed of displacement (P/V) is within a defined range shown on a graph of P/V against W s. Laser beam and the metal powder are applied by a projection nozzle incorporating a truncated section portion with a central boring for the passage of the laser beam and some channels extending in the wall of the truncated section for the supply of the metal powder.

Title: Method and device for encoding and reconstructing computer-generated video holograms
Filed: 2007-02-22
Abstract: A method and a device for encoding and reconstructing computer-generated video holograms using a conventional LC display: it provides holographic reconstruction of three-dimensional scenes using electronically controllable pixel in a holographic array (3) with a conventional resolution, and is reasonably free from flickering and cross-talk. Reconstruction is in real time, and for both eyes at the same time, over a large viewing zone. The method takes advantage of an optical focusing means (2) in order to image vertically coherent light emitted by a line light source (1) into viewing windows (8R, 8L) after modulation by the pixel array (3). The holographic reconstruction (11) of the scene is rendered visible from viewing windows (8R, 8L) for both eyes of an observer by way of diffraction at the pixels. According to the invention, the controllable pixels are disposed in vertical pixel columns (15, 16), which encode separate holograms of the same scene for each of the viewer's eyes (R, L), where said holograms are one-dimensional in the vertical direction and horizontally interleaved. An image separation means (7) with separating elements arranged parallel to the pixel columns reveals the respective pixel columns (15, 15' or 16, 16') for one eye and covers them for the other eye.

Title: Inner cutting blade
Inventor: NAKADA HIROSHI
IPC: B28D5/00
Filed: 1978-08-18
Abstract: PURPOSE:To manufacture a inner cutting blade for cutting off crystal with high accuracy, by providing a central hole which is defined by connecting the front ends of moving radii proportional to the radial moduluses of elasticity of a material metal and by uniformly tensioning the blade in the radial direction to make the central hole perfectly circular. CONSTITUTION:When the inner cutting blade 1 is not stressed, the central hole of the blade is shaped as an ellipse whose minor axis extends in a rolling direction 3 corresponding to the small modulus of elasticity of the material metal and whose major axis extends perpendicularly to the rolling direction. The material metal 2 is a rolled stainless steel (SUS 304) with a thickness of 0.12mm or the like. Abrasive grains are fixed on the inner cutting blade 1. When the blade is used for cutting-off, the peripheral part 4 of the metal 2 is uniformly elongated in the radial direction so that the blade 2 has an equal rigidity in all directions and is shaped to a perfectly round form 5. Since said form is maintained in the cutting-off, self- sustained oscillation is eliminated and the accuracy of the cutting-off is raised.
