Title: Power supply of an explosion- proof diesel locomotive
IPC: B61C5/00
Filed: 1979-11-30
Abstract: The invention provides an improved power supply system for the principal power transmission and ancillary plants as well as the controlling, monitoring, protecting and signalling units (9, 10, 11, 12) of an explosion-proof diesel locomotive. The power supply system consists exclusively of mechanical (5) hydraulic (6) and pneumatic (4, 8) power-transmitting elements and has no electrical power-transmitting elements. The pneumatic elements are powered from an air reservoir (8) replenished by an air compressor (4) only when outside an explosion danger zone. The system requires no central energy accumulator, the prescribed compulsory position indicating and lighting lamps are completely explosion-proof lamp-units which have their own internal, discrete exchangeable or rechargeable batteries. The design of the locomotive renders it unlikely to initiate an explosion during travel through an environment which is liable to explosions. <IMAGE>

Patent GB-2056168-A (GB)
Title: Method of fabricating P-N junction with high breakdown voltage
IPC: H01L29/74
Filed: 1980-04-16
Abstract: A layer with a gradual impurity concentration profile but with its extent largely determined by a slow differing impurity (which produces an abrupt profile) is produced by introducing the slow differing impurity into a first zone and a second faster A diffusing impurity of the same conductivity type into a second zone and merging the two zones. Ions of the first impurity (arsenic) are implanted in the substrate, to form zone 10 at a first depth 12 using a given acceleration energy, followed by heating to partially diffuse the implanted ions to form zone 10'. Ions of the second impurity (phosphorous) are implanted in the substrate, using the same acceleration energy to form zone 14 at a greater depth 16 in the substrate than the first zone 10. The first zone 10 has a substantially greater impurity concentration than the second zone 14. The first and second impurities are diffused by heating the substrate to cause the layers 10, 14 to merge to form a single impurity layer composed of both the first and second impurities. The resultant impurity layer is substantially immune to subsequent heating fabrication steps and has a relatively gradual distribution profile such that the formed P-N junction has a relatively high breakdown voltage. <IMAGE>

Title: Electric potential detector
IPC: G01R19/155
Filed: 1980-04-24
Abstract: A device for detecting potential in an insulated conductor comprises one or more conductive plates 10, 12 which in use are positioned on the insulator. The plates are connected in series with a display device 26 and a conductive member 28 which the user touches to complete a circuit to earth through his body. The display device is a LCD, neon lamp, or other device operating on a small current. If the conductor is carrying a.c. potential or interrupted d.c. potential, a small current is capacatively induced in the series circuit, and the display device lights up. A modification (not illustrated) employs segmented plates which can be selectively switched, to provide a greater plate area for lower voltages. <IMAGE>

Patent GB-2062308-A (GB)
Title: A Stored Program Digital Data Processor
IPC: A61N1/365
Filed: 1978-08-16
Abstract: A store has addressable locations in two portions RAMA and RAMB. An instruction highway 27 enables locations to be addressed independently in RAMA and RAMB. An adder 39 adds the contents of two addressed locations in RAMA and RAMB respectively. A register 40, 41 receives the sum from the adder and also interrupt signals. A connection 37 enables the contents of part 40 of the register to be written back in RAMA. A connection 38 enables the contents of register part 41 to be written back in RAMB. Control is by a program counter and instruction ROM which provides instructions on the highway 27, shift pulses RCK for the register 40, 41 and a latch enable signal LE for enabling a latch 35 to store an output word from the highway 27. One bit (JUMP) and a bit from the instruction ROM control presetting of the program counter to a jump address. <IMAGE>

Patent GB-2062330-A (GB)
Title: Electrochromic display device
IPC: G09G3/16
Filed: 1980-10-14
Abstract: An electrochromic display device has an electrolyte contained between two spaced-apart substrates. A set of display elements including first and second display elements are disposed on the surface of at least one of the substrates in contact with the electrolyte, and a counter electrode is disposed on the surface of the other substrate in contact with the electrolyte. Each of the display elements comprises a transparent electrode and an electrochromic layer disposed on the transparent electrode such that the display element exhibits either colored or bleached states depending on the amount of electric charge held by the display element. A charge transfer voltage is selectively applied between preselected bleached and colored display elements to effect transfer of electric charges through the electrolyte to thereby change the display state. Deterioration of the coloration exhibited by the colored display elements is compensated by applying a constant voltage between the first display element and the counter electrode, the value of the constant voltage being lower than that of the charge transfer voltage, and control circuitry controls the application of the constant voltage such that the constant voltage is applied before each predetermined number of transfers of electric charge held by the first display element to the second display element thereby maintaining the degree of coloration of the colored display elements.

Patent GB-2072693-A (GB)
Title: Adhesive containing starch
IPC: C09J103/02
Filed: 1981-03-20
Abstract: An adhesive, particularly for use in the making of corrugated cardboard, consists of starch, water and alkali in such proportions that the mixture contains 10 to 40% by weight of starch solids and has a pH value of 8 to 13, a gel point of 52 to 75 DEG C and a Stein-Hall viscosity of 20 to 120 seconds. The starch consists of completely gelatinized starch and partly swollen starch in a weight ratio between 0.2:100 and 2:1, which results in a greatly increased gelatinization rate and thereby increased wet tack of the adhesive, and this in turn permits greater machine rates in the making of corrugated cardboard. The adhesive may be produced by first maintaining a mixture of ungelatinized starch and water at 20 to 100 DEG C, preferably in the presence of an acid or a base, until the starch is completely gelatinized, then adding more ungelatinized starch and optionally water, adjusting pH to between 8 and 13 and maintaining the mixture at 20 to 75 DEG C until it has reached a Stein-Hall- viscosity between 25 and 130 seconds, followed by the addition of a reaction inhibitor, preferably borax, alum, another acid material, cold water or ice, in an amount such that the gel point of the mixture will be between 52 and 75 DEG C. The initial complete gelatinization of ungelatinized starch may optionally be replaced by an addition of completely gelatinized starch powder.
