Title: Image intensifier tubes
IPC: H01J31/50
Filed: 1979-03-05
Abstract: Battlefield image intensifier tubes are protected against damage caused by the relatively enormous heat and electron energy developed if the intensifier should by accident be pointed at a bright light source (such as a shell flash) by a collar- like resistive element 22a placed around the rim surface of one of the tube's windows and connected so as to act as a high resistance between the relevant photo-layer 12 and its window mounting flange 3 (and hence the H.T. power source). This causes both a temporary reduction in down-tube potential and - when, as is preferred, the photo- layer is the cathode - a pinching-out effect of the electron flow from any point-like source on the photocathode when the tube is subjected to highlight overload conditions. <IMAGE>

Patent GB-2020865-A (GB)
Title: Memory Bank Switching
IPC: G06F12/04
Filed: 1979-04-26
Abstract: A data processing system includes, e.g. four memory blocks (MB0-MB3) each of which stores two different word lengths, e.g. two thousand 18-bit words (EAO) and sixty-two thousand 16-bit words (A). The shorter 16-bit words are instructions with a 9-bit address part (V) which allows any one of a subset (EAO(SO)) of the 18-bit words in the same memory block to be addressed. The resulting accessed 18-bit word is used as an indirect address to any word in any one of the four memory blocks. Thus a processor based on 16- bit words may access a memory which is four times larger than the sixty-four thousand word memory usually regarded as the upper limit in a 16-bit processing system. The remaining subset (EAO(SI)) of 18-bit words not used for indirect addressing can be used for data. As 64K memories with 18 bits are not commercially available it is contemplated that 64K memories of 16-bit words be used with two 64K memories of 1 bit each to make up the 18 bit words. <IMAGE>

Patent GB-2048343-A (GB)
Title: Improvements relating to getting machines for underground mining
IPC: E21C29/02
Filed: 1980-05-01
Abstract: A getting machine (1) for underground mining is provided, which can traverse on a face conveyor (4) and engages, by means of at least one driving wheel (11) which is drivingly coupled to the machine winch, with a gear rack (8) which is installed on the slowing side of the face conveyor. The machine body (2), whose longitudinal axis extends parallel with the floor, lies, in a direction transverse to the longitudinal axis, in a sloping position, falling from the working face to the slowing side. This enables the driving wheel (11) to mesh directly with gear rack teeth which are positioned so that the axes of the gear rack driving pins (13) extend parallel with the inclined plane of the machine body (2). This avoids the need for intermediate gearing with the result that good meshing characteristics may be expected even on an undulating floor. <IMAGE>

Patent GB-2056808-A (GB)
Title: Power transistor protection
IPC: H03K17/082
Filed: 1980-08-13
Abstract: Power transistors are protected against being damaged by means of overload current by a device which monitors the current flow therethrough and switches the power transistor off when the current exceeds a predetermined value. When the voltage across a resistor (9) exceeds a given value it causes a pair of transistors (Q2 and Q3) to latch on in thyristor mode, which clamps the voltage at the base electrode of the power transistor (Q4) to a value which holds the power transistor non-conductive. A capacitor C2 improves the immunity of the circuit from responding to noise or other line borne transients. An emitter coupled stage (Q5 and Q6) improves the current sense capability of the circuit so as to make the trip current level substantially independent of temperature. The protective circuit is designed to be used for either transistor assisted contact ignition systems or opto-electronic ignition systems. <IMAGE>

Title: Production of powdered metal articles
IPC: C22C33/02
Filed: 1981-04-29
Abstract: A method of forming an article e.g. a bearing assembly A by bonding together two or more members formed from powdered metal, comprises forming a first member 10 having the desired configuration from an iron base powdered metal containing a sufficient amount of copper to cause the member to expand upon sintering, forming a second member 12 into a configuration such that it is adapted to engage in an interference fit with at least part of the first member, the second member being formed from an iron base powdered metal containing a sufficient amount of nickel to cause the member to shrink upon sintering, fitting the second member to the first member to form an interference fit therewith and such that on sintering the first member expands against the second member which, in turn, shrinks against the first member, and heating the assembly of the first and second member at a sintering temperature which is sufficient to cause the members to become metallurgically bonded together. Preferred compositions for the copper and nickel bearing powders are, respectively, by weight, Fe 93-96%; Cu 3-6%; C 0.5-1% and Fe 95-97.5%; Ni 2-4%; C 0.5-1%. <IMAGE>
Patent GB-2098539-A (GB)
Title: Meat portioning using a bandsaw
IPC: B26D1/46
Filed: 1981-05-20
Abstract: By using a linear blade speed of the saw in the range of 15,000 feet per minute upwards with a reduction in the number of teeth per inch to three, feed rates of 30 r.p.m. of a carousel containing three hunks of high density compressed meat to be portioned, have been achieved. The speed of the blade and the tooth pitch and speed of presentation of the individual hunks of meat to be portioned are selected so that a local momentary heating of the meat stuff occurs as the blade is presented thereto, the heating being sufficient to momentarily defrost the meat stuff in the region of the cut so preventing the saturation of the blade with frozen meat which has tended to represent the limiting factor with this type of apparatus. Means is provided for adjusting the speed of the blade, the speed of the carousel and for changing the tooth pitch of the bandsaw if required so as to optimise the cutting perimeters for different types of meat stuff. A selector/indicator may be provided to allow an operator to select from a series of options, the best linear speed and carousel speed for any given meat stuff.
