Title: Semiconductor device
IPC: H01L29/8605
Filed: 1978-06-28
Abstract: A semiconductor device includes an N-conductivity type resistor layer 12a formed in the main surface of the (110) face of a silicon substrate 11. The resistor layer 12a extends along a crystal axis shifted by 45 DEG  from the [001] axis to allow a current to pass along its crystal axis. It has been found that the resistance value of a resistor layer of such orientation is less affected than other orientations in the same plane by the thermal stresses induced in the layer by the shrinkage of a plastics resin envelope 18 during the moulding thereof. <IMAGE>

Title: A mobile snow disposal apparatus
IPC: E01H1/10
Filed: 1978-07-04
Abstract: A vehicle is provided with a water tank (11) and a high pressure pump (13) which supplies a horizontal nozzle unit (16) on the front of the vehicle with high pressure water at a high rate of flow. The water is jetted downwardly and forwardly in front of the vehicle and produces almost instantaneous melting of lying snow by the energy released on its impact. Pressures of the order of 40 Kg/cm<2> and flow rates of 40 litres/min are utilised. The water may be pre-warmed by pump friction. The apparatus is demountable on a truck and is capable of clearing snow without damage to the road surface at a high rate. Adjustment of angle of attack and height of nozzle unit by hydraulic (water) cylinders (25, 28) enable packed snow and sheet or plate ice to be dislodged from the road surface. <IMAGE>

Title: Pressure booster system for fluids
IPC: B01D15/08
Filed: 1979-08-09
Abstract: For delivering fluids at high pressure, for example to a liquid chromotography column 240, with a minimum of pulsation and at an accurate flow rate, a pressure booster system includes low pressure injector means 12 (which in the illustrated case comprises first and second cam-actuated pumps 46 and 48) which supplies respective liquids through respective valves 94 and 96 and an accumulator 106 to a high pressure pump 158 the output of which is at the desired high pressure.

Title: Reflector Lamp
IPC: H01J61/34
Filed: 1979-09-26
Abstract: A reflector lamp in which a lamp envelope 7 containing a light source, in particular a short arc discharge source, is mounted in an ellipsoidal reflector 3 with the light source at or near the primary focus of the reflector.

Patent GB-2077536-A (GB)
Title: Digital to analog converter
IPC: H03M1/00
Filed: 1980-06-04
Abstract: In one of six embodiments, a digital to analog converter has an input register 101 for receiving base 2 binary digital input signals, including negative integer representation in two's complement form. The input signals on registering in the input 101 are converted into a base 2 binary range representing only positive integers, and are multiplied by three as fractions by a multiply by three unit 103 and a recycle register 105 to produce a serial output of a binary coded ternary number which is converted into parallel form by a serial to parallel converter 106 and clocked into an output register 107. The outputs of the register 107 drive switchable level changers 108 which apply positive and/or negative reference voltages of equal magnitude to ladder network 109 of resistors with base three weighting. The resultant analog output signal has range in which zero is the mid-point, and the operation of the converter is such that whenever a series of digital input signals to the input register 101 requires there to be a departure which is in either direction from the analog zero output, the number of switchable level changers whose states are changed at any stage in the resultant sequence of changes is independent of the direction of the departure from the analog zero. <IMAGE>

The material is just soft enough to prevent the ingress of liquid when the surface is immersed in liquid.   (b) electro-painting the unmasked surface in an electrolytic bath, e.g., with an epoxy-phenolic paint. (c) removing the flexible or pliable material so that the region(s) to be plated is or are left exposed.   (d) electro-plating the region or regions with the precious metal.

Patent GB-2071150-A (GB)
Title: Shear thickening well control fluid
IPC: C09K8/502
Filed: 1980-09-24
Abstract: Shear thickening fluids which comprise a water swellable material (e.g., clay), capable of rapidly forming a paste having a strength of at least 1000 Pa with the aqueous solution employed and present in sufficient concentration to form such a paste a nonaqueous hydrophobic material comprising a hydrocarbon material and a surfactant and/or strengthening agent, and an aqueous solution comprising water and a water swellable/ water soluble polymer, wherein the clay and water-polymer solution are kept separated by an intervening hydrocarbon-surfactant phase. Preferable, the hydrocarbon-surfactant phase (oil phase) encapsulated clay is suspended in a continuous phase comprising the water-polymer phase; however, suspension of clay and separate, discrete water-polymer droplet in a continuous oil phase are also possible as are compositions commonly called "double emulsions", as well as systems which are bicontinuous. The intervening oil phase prevents the interaction between the water-polymer and the clay phases and results in a stable, non-reacting, pumpable composite, until such time as the oil barrier is ruptured by deliberate application of a sufficiently high shear force. Upon such rupture, the materials mix and interact resulting in a semi-rigid high strength paste. Various well control problems such as oil and gas well blowouts can be controlled by use of the above-described composite. The composite is pumped down the well pipe. Upon application of a sufficiently high shear as by exiting the orifices of the drill bit, needed to rupture the oil envelope, the clay and the water-polymer interact, resulting in the formation of the semi-rigid, high strength paste which cures the well control problem, sealing the well circulation thief zone or terminating or preventing a blowout.
