Abstract: 888,483. Route setting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and EMERSON, E. R. April 17, 1959 [April 2, 1958], No. 10587/58. Class 105. In a railway signal and points control system, particularly for use in collieries, a route through a points is set and the associated signal cleared by apparatus comprising route setting track side plungers operated by the train driver and vehicle-operated treadle means. A track section, Fig. 1, includes points 2 and two routes X and Y. A train moving in direction 3 operates a track treadle AQ when halted at signal A and if points locking relays AXLR and AYLR have both been switched to their normal (release) positions by the release of relays XQR and YQR (not shown) under the control of route exit treadles XQ(A), XQ(B), YQ(A) and YQ(B), the treadle brings into operation a relay ASR (not shown) which remains energized during the period the treadle is depressed and operates " ready " lamps associated with plungers AX and AY. Plunger AX is disposed on the left of the track in the direction of travel and controls left-hand route X. If the plunger is operated when the route is already set for X a points control relay 1WR remains released since its circuit is open at a back contact (b.c.) of points normal detection relay INKR (not shown) and relay IWR is locked in this position by relay AXLR which is reversed via f.c. (front contact) relay ASR, plunger contact PAY unoperated, plunger contact PAX operated, a contact of relay IWR in normal position, f.o relay INKR, treadle contact XQ(A) unoperated and b.c. relay XQR. The signal A aspect is changed to green (relay DGE) via f.c. relay INKR, a contact of relay AXLR in reverse and f.c. relay ASR. If the route is not set up relay IWR and subsequently the points are switched to their normal positions via f.c. relay ASR, plunger contact PAX operated, b.c. relay INKR, a contact of points position repeater relay IWPR at normal and contacts of lock relays AXLR and AYLR at normal. The points are locked in normal position by relay AXLR and the signal aspect changed to green via the previously traced circuits. Repeated operation of the points to remove an obstruction between the switch and stock rails is made possible via the de-energized back contacts of normal and reverse points detection relays INKR and IRKR.

Abstract: 1298754 Measuring dimensions R L CHITTOCK and B F LAMBERT 5 March 1970 [24 March 1969] 10673/70 Heading G4H The dimension of an object overlying an optical grid having reflective markings or its position along the grid is determined by photoelectrically scanning the grid and counting the number of graduations unobscured by the object. If the object is long, one end is located at a datum and only its other end overlies a grid, alternatively a grid and photo-electric detector may be used at each end of the object. The object may be a vane of a meter and several meter vanes each with respective grids may be scanned sequentially, each vane identified by a coded grid which generates a code-signal during scanning. A television raster scanning type of camera is used as a photo-electric detector with straight line or circular scanning and a counter counting the scans per frame selects the scans which scan the grids. A further counter receives the pulses generated by the exposed portions of a grid and provides an output to an indicator, or supplies a binary coded decimal signal output to a computer.

Abstract: 1507820 Semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 17 March 1976 [10 April 1975] 10773/76 Heading H1K Read-out from a memory device, in which the presence or absence of charge trapped at the interface of superposed gate dielectric materials of an IGFET determines the logic state of the device, is effected by applying to the drain region a potential substantially less than the avalanche voltage (pulse 53) and to the gate electrode a potential just greater than the threshold voltage (pulse 54) and detecting current flow between the substrate and the drain region. The presence of such current flow (pulse 62) implies, for an n channel device employing the illustrated polarities, the absence of electrons stored in the gate dielectric, while the absence of substrate-drain current flow implies the presence of stored electrons (READ O). Electrons are stored (WRITE O) by applying to the drain region a potential below the avalanche voltage (pulse 32) and to the gate a potential substantially above threshold (pulse 30). Erasure of stored electrons (WRITE 1) is effected by applying to the drain region a potential above the avalanche voltage (pulse 34). The gate dielectric may comprise a lower layer of SiO2 and an upper layer of Si3N4, Al2O3 or SiOxNy.

IPC: C10G45/24
Abstract: 108,019. Lucas, O. D., Palmer, T. C., and Perkin, F. M. July 17, 1916. Mineral oils, purifying, &c.-Mineral oils are heated in presence of ammonia for removing impurities such as sulphur and for hydrogenating the oil. The reaction may be carried out at such temperatures that the ammonia is decomposed and the oil is cracked, and at increased pressure to keep the oil in liquid form or at ordinary or reduced pressures. For treatment in the liquid form, oil, in which ammonia is dissolved or mixed is forced at a high velocity and pressure through tubes heated to 400-500‹ C. for treatment without cracking, and to 550-700‹ C. for cracking, and the pressure on the oil is suddenly released. The sulphur is converted into sulphuretted hydrogen or other form which can be removed by washing with caustic alkali, preferably containing a metal oxide, or by litharge or hydrated oxide of iron. Carbon, bituminous substances &c. are precipitated and can be removed. Vapours may be collected separately and condensed. For treatment in the vapour form, the vapours mixed with ammonia are passed through a heated retort to a condenser. The permanent gases from the condenser may be used to take up ammonia from liquid ammonia for addition to the vapours.

Abstract: 726,723. Toy railways. TRIX, Ltd. Jan. 28, 1954 [April 22, 1953], No. 11038/53. Class 132(3). A device for a toy railway raises imitation coal or other material from an open container and deposits the material into a tipping truck which may be moved round on a track from the material receiving position to the open container, the material then being tipped into the container from the truck. A conveyer belt 16 raises material from a hopper 11 and deposits it on a conveyer band 27 supported in a girder member 20 which is removably secured at one end to a main stand 2. A shoot 32 at the other end of the member 20 is provided with an inwardly directed wall 33 on to which the material drops as it falls into a tipping truck 36. When the truck is loaded, an electric motor driving the conveyers is switched off and power for a locomotive drawing the truck is switched on. On arrival at the hopper 11, the truck is tipped by electromagnetic means 37, and the material is deposited in the hopper. The truck may thus be continually charged, moved round on the truck and tipped. Resilient feet 1a allow the hopper to be vibrated by the motor to cause the material to ride down the side of the hopper. Manual switches for controlling the device are indicated at 4. There may be more than one girder member 20, members then being joined end to end.
