Abstract: 994,212. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. July 26, 1961 [Aug. 2, 1960], No. 26726/60. Heading H1K. The base of a semi-conductor device is treated so as to provide a continuous transition of the order 1000 Angstroms thick in which the energy gap is wider than in the interior of the base material. The treatment isolates inherently unstable surface phenomena which adversely affect the device. The base material may be silicon or germanium or any intermetallic compound of the two metals, one from Group III and the other from Group V in single crystal form. When the base is of germanium it may be sputtered with silicon and heated to diffuse the silicon into the surface of the base. A silicon-indium alloy may be introduced to form the layer. The layer may also be provided by forming a chemical compound with the surface material of the base, the compound being a semi-conductor or insulator with a crystal structure that fits the structure of the base material to provide the wider energy gap.

Title: Process and apparatus for continuous casting of metal strands
IPC: B22D11/128
Filed: 1972-06-08
Abstract: 1398891 Continuous casting BATTELLE MEMORIAL INSTITUTE 8 June 1972 [9 June 1971] 26897/72 Heading B3F The surface of a continuously cast strand, e.g. a slab 11 of steel, guided by rollers 9 from a cooled mould 1, is subjected along the guide path to the action of a gaseous medium, such as water vapour or air or a mixture of these, having, at various regions of the path, about the same pressure as that of the ferrostatic internal pressure of the strand. This is said to permit a reduction in both size and number of the rollers 9 since a degree of their function is assumed by the fluid. In the apparatus shown, the strand passes through apertures 33a-33g (a few millimetres bigger than the strand section) in partitions 3a-3g which separate an airtight casing into compartments 2a-2g and a compartment 4 to which fluid is supplied through nozzles 10, there being at least two in each compartment, one on each side of the strand. To control the relative pressures in the compartments they are each connected to the next through pressure-control by-pass valves 14a-14g, and compartment 2a has an outlet valve 13a. Hot water may be injected through the nozzles 10 to vaporize on the strand 11 and compartment walls. The pressure of vapour so produced is made progressively higher from compartment to compartment in progression from the top compartment. The bottom compartment 4 may be divided by a labyrinth divider (8) into upper and lower portions interconnected by a pressure-control by-pass valve. A higher pressure in the lower portion may provide some support for the bar 11. Either the series of compartments 2a-2g or the compartment 4 may be replaced by a conventional guide path portion. Water vapour may be recycled by passage through a condenser or two. The mould may be horizontal with a horizontal airtight casing for first receiving the emerging strand 11. The casing may be divided into upper and lower compartments by a labyrinth divider and liquid may be injected on the lower side of the strand. or on both sides. The cooling water injection nozzles may be grouped in cowls, Figs. 7-8 (not shown), of circular, rectangular or oval section. They each have an open side located adjacent the surface of the casting (particularly the undersurface) with a multiple rim providing a baffle so that a higher pressure is maintained in the cowl than in the surrounding compartment. A flexible, articulated starter bar, Figs. 10-12 (not shown), carrying a plate head, is withdrawn as the casting descends, into a rigid tube (30) while the latter is stationary extending into the compartment 4 through an end seal 6. The tube (30) is withdrawn with the starter bar when the plate head arrives at the horizontal portion of the guide path. A difference in pressure between the upper and lower portions of the compartment 4 lifts the tube and casting above supports (31) on which the tube has hitherto rested.

Title: Improvements in or relating to gyroscopes and rotor attitude sensing apparatus
Inventor: VOLK HELMUT M
IPC: G01C19/28
Filed: 1969-05-28
Abstract: 1,221,377. Photo-electric sensing of gyroscope attitude. HONEYWELL Inc. May 28, 1969 [May 28, 1968], No.27003/69. Heading G1A. The spherical rotor 10 of a gyroscope spins relative to a support 12 about a spin axis which varies in orientation relative to the support, this variation being sensed by two or more pick-offs which monitor a pattern 14 on the surface of the rotor. Since no meaningful information can be obtained from a pick-off monitoring a polar region of the rotor, the positioning of the pick-offs and the design of the circuitry, is such that the output of only one pick-off - that which is monitoring a preferred range of latitudes on the rotor - is selected to be indicated at any one time. Although it is stated that the pattern may be magnetic or luminous, appropriate pick-offs being used, the embodiment described uses a rotor bearing light and dark pattern areas, and photo-electric pickoffs 20 and 22 associated with respective light sources 16, 18. The output of each photo-detector is of square waveform, the mark-space ratio being proportional to the width of the dark and reflecting areas passing the detector. The preferred zone to be monitored is that B, as opposed to polar regions A, C. The detector circuitry is arranged to provide three indications:- the value of latitude, or angular attitude, of the rotor with respect to the support (indicator 46); an indication (at 42) of which detector is monitoring the zone B; and an indication at 86 of which hemisphere of the rotor ("north" or "south") is being monitored. All these indications are fed to a computer 90 which keeps track of the total angular movement through 360 degrees of the rotor. For detector selection indication, the output from detector 18 is filtered (28) and the amplitude of the resulting signal analyzed by detectors 30, 32 and logic 34 to decide if it is viewing the preferred zone B. If it is, gate 36 is opened to allow detector 22 output to be indicated. If it is not, then detector 20, which is 90 degrees displaced with respect to detector 20, must be viewing zone B, and gate 40 is therefore opened to allow its output to be indicated. At the same time, the logic 34 feeds detector indicator 42 with the required information. For hemisphere indication, the output of the detector 20 only is used in order to detect when it passes by the rotor equator. The output is fed to a function generator which generates a perfect squarewave simulating the signal which the detector would generate when level with the equator, against which the detector output itself is compared by flip-flop 78. When the detector pulses are longer than the "equator" squarewave an output is produced on line 82 and when shorter on line 84. The squarewave function generator is detailed in Fig.2 (not shown), and utilizes a trigger circuit turned off by its own output received through a delay path whose time constant is modified by an integrator circuit in dependence on the deviation of the trigger output from a true squarewave.
