Abstract: 566,688. Vehicle &c. lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 31, 1943, No. 21905. Convention date, Jan. 6, 1943. [Class 75 (iv)] In a vehicle or other lamp of the type in which the enclosure for the light source is filled with air or other gas, an easily collapsable and expansible member communi. cating with the enclosure provides space for the gas filling to expand with rising tempera. ture. In the vehicle lamp shown in Fig. 1, the member con. sists of a sleeve 21 of soft rubber, oiled silk, &c. secured by rubber rings 22 between lamp cable 20 and a flange 23 on the reflector 11 surrounding the base 16 of the light bulb 17. Alternatively, as shown in Fig. 2, the base 16 is soldered to the reflector 11 and a rubber or silk bag 24 is attached to a tube 27 opening into the lamp reflector 11. In another construction, a bag is attached by a rubber ring to a flange surrounding an opening in the reflector. To eliminate moisture, the lamp may be flushed. with dry air and a getter such as calcium chloride may be disposed in the sleeve 21, bag 24, conduit 27, or on the cable connector member 19.

Abstract: 836,844. Valves. McKINNON, J. V. Aug. 13, 1958 [July 11, 1957; July 21, 1958], Nos. 22010/57 and 23306/58. Class 135. A sluice valve comprises a closure member 17 coacting with opposed seating rings 18, 19 and tapered in a direction at right-angles to that of actuation. As shown in Fig. 2, one face of the closure member is formed at right-angles to the axis of the seating 18 whereas the opposite face is inclined to the axis of the seating 19 and the closure member is urged laterally by a bowspring 21 to make contact with the seatings. The closure member carries a nut 15 coacting with a screwed spindle 14 rotation of which actuates the valve. An inclined surface 25 on the closure member coacts with a surface 24 in the housing as the closure member approaches its closed position to cause a wedging action. The spindle 14, which passes through a spring- loaded gland 12 provided with a lubricator 31, is formed with a thrust collar 27 which may be provided with ball-bearings and acts to seal off the gland 12. The valve housing is fitted with a drain plug 26. For actuation from a distant point, e.g. when the valve is fitted at the bottom of a tank in a ship and a hand wheel is provided on the deck of the ship, the hand wheel is mounted on a spindle that is connected to the valve spindle 14 by Hooke's joints and a sliding joint. The hand wheel spindle is mounted in a deck fitting provided with ball and taper roller bearings and glands.

Abstract: 154,370. Adams, S. H. Sept. 11, 1919. Tanks.-In the preliminary treatment of sewage, the liquid is passed over a floor or screen d, Fig. 2, in a catchpit e, across a sloping floor, and then upwards through a screen d<1> in a catchpit o. Sand and detritus falling through the screen d and flocculent matter retained by the screen d' pass respectively into ejector chambers h, r, from which they are discharged intermittently by air or other fluid admitted under pressure, preferably through automatically-operated timed valves. Two or more catchpits e arranged in parallel and each provided with an ejector may be used. The screen d<1> may be inclined. The chamber r may be formed as a pipe with a plurality of inlets for the sewage matter and the fluid under pressure. To cleanse the screen d<1>, the liquid above is allowed to pass downwards to the ejector. In the modified apparatus shown in Fig. 4, the first catchpit is omitted and duplicate apparatus is used in parallel. The sewage passes from the catchpit e through a settling-chamber ! l and is discharged by a centrifugal pump m driven by a motor o. A valve p allows the sediment in the chamber l to pass back into the catchpit. An electric motor q drives a compressor r delivering air to a receiver s, from which it is supplied as required to the ejector.

Filed: 1955-08-04
Abstract: 794,128. Semi-conductor devices. GENERAL ELECTRIC CO., Ltd. Aug. 3, 1956 [Aug. 4, 1955], No. 22485/55. Class 37. A method of making a semi-conductor device comprises dropping molten tin heated to at least 1050‹ C. through an apertured mask on to a body of silicon also heated to 1050 ‹C. or more, a significant impurity being dissolved in the molten tin at some stage. After the surface silicon has been dissolved by the tin the assembly is cooled to precipitate a layer of silicon containing a significant impurity on the original silicon body. In one embodiment a wafer 5 of 20 ohm cm. N-type silicon, previously etched in a mixture of glacial acetic nitric and hydrofluoric acids with bromine, is placed in a refractory jig comprising a recessed plate 1, a fitting tube 2 with a diametral hemi-cylindrical recess and an inclined plane 12 formed in its upper end, and a rod 8, slotted as shown, running in the recess. Pellets 13 and 14 of pure tin and aluminium respectively are dropped down the inclined plane and are held between it and the rod. The whole assembly is then moved slowly through a tubular enclosure through which forming gas is circulated. The enclosure is water-cooled at its extremities but heated to 1160‹ C. at its centre. As the assembly approaches the centre the pellets melt but are held in place by surface tension until the centre is reached when the rod is rotated by engagement of its lever 9 with a projection in the enclosure to release the tin which drops on to the wafer carrying the aluminium with it. The assembly is cooled as it moves out of the enclosure and the resulting PN junction body etched and finally washed and dried.

Abstract: 1492730 Measuring linear displacements INTERNATIONAL BUSINESS MACHINES CORP 2 June 1976 [2 June 1975] 22813/76 Heading G1N [Also in Divisions G4 and H3]  In a digitizing tablet apparatus, the position of a sensor (e.g. manual "pen") capacitively coupled to an X-Y grid of wires is detected by selective energization of the wires with an alternating voltage signal. As disclosed, the alternating signal picked up by the sensor is converted to D.C., then digitized and fed to a processor. Initially, the alternating signal (a pulse train) is applied to all the X wires to detect application of the sensor, whereupon a shift register having a stage for each X wire (except the leftmost, which is earthed) is set to all "ones" and shifted right (with entry of "zeros" into the left end), each stage holding "one" causing the alternating signal to be applied to the corresponding X wire. The register can also be shifted left (with entry of "ones" into the right hand end). A bidirectional counter counts the shifts. When the boundary between non-energized and energized X wires reaches the sensor, the processor stops the shifting, the count indicating the coarse X position of the sensor. The sensor output is divided by a reference signal and multiplied by the distance between adjacent wires to give the fine X position, the reference signal being the sensor output when the alternating signal is applied to all the X wires. The Y position is next determined similarly.

Abstract: 634,877. Building blocks. LUNDHOLM, C. H. Aug. 16, 1947, No. 22827. [Class 87 (i)] Adjoining wall &c. blocks are engaged at their edges by two different co-operating members each carried by a rod extending in the respective block at right-angles to the joint and embedded therein for most of its length. As the blocks approach one another one member is resiliently deflected by the other and then returns to its previous position thus slipping the blocks together. Building blocks 1 having longitudinal and transverse rods 3, 4 moulded therein are recessed at their edges to accommodate resilient and rigid engagement members 6, 7, which are screwed on to the rod ends. Member 6 comprises a metal piece 62 with curved portions of piano wire anchored to it providing a heart-shaped space into which the rigid member 7 is received when adjacent blocks are brought together. The recesses are finally filled with quick-drying cement mortar. The transverse upright rods 4 are preferably much  thicker than rods 3 which may pass through holes in rods 4. The resilient members may be located at the upper and the rigid members at the lower edges of the blocks.
