Filed: 1920-11-30
Abstract: 175,124. Eustege, T. P. Nov. 30, 1920. Stays.-A telescopic stay comprises an outer tubular member 1 formed with a longitudinal slot 2 and transverse depressions 9 or transverse slots communicating with the slot, and an inner rod 3 with an enlarged head 4 sliding within the tube 1. The head 4 may be rotatably mounted on the rod 3. A screwed pin 5, Fig. 3, works in a screwed hole in the head 4 and projects through the slot 2, a nut 6, integral with the pin, locking the parts together. A collar 7 engaging a recess in the head 4 prevents undue retraction of the pin. In a modified construction, Fig. 5, in which the nut 17 is rotatably mounted on the pin 18, the pin may be pushed downwards until a head 21 thereon has passed through a hole 20 in the bottom of the outer member when the parts are slack, and the window may be slightly opened to an extent determined by the length of a second slot 19 in the bottom of the outer member, but in order to open the window farther it is necessary to close the window and draw the pin upwards through the hole 20.

Title: Process for the production of semiconductor components
IPC: H01L21/00
Filed: 1971-07-19
Abstract: 1361851 Semi-conductor devices ARBEITSSTELLE FUR MOLEKULARELEKTRONIK 19 July 1971 33776/71 Heading H1K A pair of PN junctions are formed simultaneously in one face of an N(P) body by forming an apertured masking layer thereon, depositing overall an insulating layer containing doping material, forming therein an aperture at least partly within the first aperture, depositing overall a second insulating layer containing doping material and then heating to diffuse the dopants in to form an N(P) region surrounded by a P(N) region. If the body is N type one insulating layer contains an acceptor (and possibly a donor) and the other a donor (while if it is P type one layer contains a donor (and possibly an acceptor) and the other an acceptor. The method as described is used to produce an NPN silicon junction transistor or a P channel JUGFET. The masking layer is of genetic or desposited silica. In the first case the first insulating layer is boron and arsenic doped silica formed by oxidation of silane in the presence of the impurities, and the second of similarly formed boron-doped silica. To form the JUGFET the layer compositions are reversed. The aperture in the first insulating layer lies at one side of the aperture in the mask and partially overlaps it in the junction transistor example and is an annulus wholly within the mask aperture in the JUGFET example. Following the diffusion step apertures are etched in the layers and masking to expose contact areas and then aluminium is deposited overall and etched back to form the base and emitter or source, gate, and drain contacts respectively. If desired the doping at the base contact site may be enhanced by another diffusion prior to aluminium deposition. Alterrative pairs of dopants are mentioned for formation of NPN silicon devices as are pairs suitable for forming PNP devices in P type silicon and germanium substrates.

Abstract: 1405036 Digital data transmission INTERNATIONAL BUSINESS MACHINES CORP 19 July 1973 [17 Aug 1972] 34534/73 Heading H4P A system for predicting signal levels of message elements in a modulo-n message stream comprises: a gating circuit responsive to message elements to generate outputs indicative of different combinations of values of elements; storage devices connected for access in response to the outputs representing respective combinations to provide predicted values of further elements; and means for applying the actual values of these further elements to the corresponding storage devices to modify their contents. As applied to a document scanning system, the points D1, D2 Fig. 2 directly above or directly adjacent an unknown point D3 are considered to predict whether D3 is likely to be black or white (i.e. "1" or "0"). The actual values of D1, D2, D3 are stored in registeres 60, 62 and the values of D1, D2 are compared by means of AND gates 72, 74, 76, 78 to produce an output on one of the lines 100, 102, 104, 106 depending on which of the four possible states that the D1, D2 combination can have.

[Also in Division F2] Two pipes are joined by remote control on the sea bottom using the following methods. In the first method, Fig. 6, an explosive ring charge is inserted in the end of pipeline 12, and a die 61 is placed over the end. The charge is detonated, causing the pipeline end to expand into the die 61 at 71. A flange 72 is welded on to the end of pipeline 37 prior to clamping in the apparatus 17. A split sleeve 66 is hydraulically clamped over the flange 72 and die 61 and draws the pipeline ends together by means of tapers 74, 65. In the second method, Fig. 10, an expansible metal ring 119, see Fig. 11, is inserted in the end of pipeline 37 prior to clamping in the apparatus 17, and is expanded into engagement with the pipeline ends after alignment. A split sleeve 117, connected to a series of retorts 126 by inlets 127 and to a series of receivers 131 by outlets 132, is clamped over the pipeline ends to form a mould cavity. Air pumped through the mould cavity via inlets 129, by-passing the receivers 126, and out via one-way valves 134 to clean and dry the cavity. Thermit mixtures of preferably iron oxide and aluminium located in the retorts 126 are ignited by charges of preferably peroxides and aluminium dust, ignited by sparks, and when the reaction is completed, the resulting metal is cleansed by fusible plugs 135 from the retorts 126 and flows through the cavity to the receivers 131 initially to preheat the cavity. When the receivers 131 are filled, further metal fills the cavity to effect the weld. Moulded exothermic charges or electrical heaters 138 may be used to preheat the mould. A pressurized feed may be used whereby the retorts 126 and receivers 131 are reversed in positions. The expandable ring 119, backed by inflatable rubber 118, may be of steel or coated with copper or ceramics. The split sleeve 117 may be removed after welding or a one-piece sleeve may be used and left in place.

Abstract: 1199301 Automatic speed-control BUNKER-RAMO CORP 28 July 1967 [28 July 1966] 34908/67 Headings G3T and TA5T [Also in Division H2] A constant-speed motor comprises rotatable magnets 18, 20, associated with a sensing coil 22 and a driving coil 24 which is energized from pulse generator 28. A transistor 26, in series with the driving coil, is controlled by signals from the coil 22 responsive to rotation of the magnet 18 so that the driving coil is energized when a pulse from the generator 28 coincides with a conductive period of the transistor. If the speed of shaft 10 tends to change due to a variation of loading, the pulse from coil 22 slips in phase, resulting in a greater or lesser effective duration of the pulse which is applied to the coil 24 whereby the speed is restored to a value which depends solely upon the frequency of the generator 28. Since the magnets 18, 20 are mutually normal there is no interaction between magnet 20 and coil 22 or between magnet 18 and coil 24. In a modification, the non- magnetic disc 16 carries a plurality of vertical permanent magnets around its periphery, these magnets having their poles arranged in the same direction. A first transistor has its collector connected to the pulse generator and its base and emitter are connected to the sensing coil. A second transistor has its emitter connected to the pulse generator, its base to the emitter of the first transistor, and its collector connected through the driving coil to a D.C. source.

Abstract: 339,454. Schõrer, (nÚe Nussbaumer), L., and Schõrer, K. J., (trading as Schõrer, Nussbaumer & Co.). May 16, 1929, [Convention date]. Winding-machines-A feeler ring that is displaced periodically by the head of a reciprocating cop; in cop or pirn winding machines, and which carries the thread guide, is held frictionally on its circular guiding rod by friction elements consisting of rollers having a concave profile adapted to fit the curvature of the guide rod. On the cylindrical guide rod 1, Fig. 1, is slidably mounted a tubular supporting member 2 which carries a conical feeler ring and thread guide (not shown), and which houses a compression spring 11. This spring normally presses the gripping boss 6 outwards, so trapping the rollers 8. between the guide rod 1 and inclined conical surface 5<1>. When the feeler device is engaged by the cop winding, the supporting member 2 is displaced to the right on the guide rod 1. The spring 11 is then compressed and the conical sleeve 5 disengaged from the rollers so that the gripping action is released. The griipping-boss 6 is pushed by the spring until the rollers lock the whole in its new position on the guide rod. The rollers are hollow and retained in position by a ring 9 passing through them and fitting in a circumferential groove 10 on the boss 6. The peripheral surface of each roller is concave so that it makes line contact with the guide rod 1, Fig. 2, and the outer peripheral edges 8<1> of the rollers are rounded slightly to fit the inclined conical surface 5<1>.
