Patent GB-2107865-A (GB)
Title: Heading-attitude reference unit with two-axis platform
Inventor: KROGMANN UWE
IPC: G01C21/16
Filed: 1982-10-14
Abstract: In a heading-attitude reference unit a two-axis, gyro-stabilised platform (12, 16) is provided. The azimuth angle ( psi p(t)) is obtained by integration of a signal from a rate gyro (52). In addition, compensation of the influence of the angular rate ( OMEGA s) of the earth is provided at a summing point (54). Velocity signals (v<c>y(t), v<c>v (t)) are derived from signals from accelerometers (34, 36) and are transformed (84) into a system of a "virtual" platform imagined to be rotated in azimuth towards the North. The transformed velocity signals (v<v>x, v<v>y) form error signals, from which, in turn, corrective signals (UT<v>x, UT<v>y, UT<v>z) are formed. The corrective signals are re-transformed (108) and are applied to torquers (30, 32) of the two-axis platform and to the integrator for the rate gyro signal, respectively. <IMAGE>

Title: Froth flotation mineral recovery process
Inventor: HENDRICKSON LUTHER GLENN
IPC: B03D1/02
Filed: 1983-02-02
Abstract: Mineral values are recovered from ground ore (or concentrate thereof) in a plurality of froth flotation steps in a commercial-scale vessel, the improvement being that agitation is effected by an impeller at a high rate, such that the Froude number is at least 2.0 (Froude number is DN<2>/g, where D is the diameter of the impeller in feet, N is the number of revolutions of the impeller per second and g is the gravitational constant in feed per square second). The method involves using, on a commercial scale, a Froude number at least as high as the Froude number used in optimum conditions on a laboratory scale.
Patent GB-2136179-A (GB)
Title: Pager Decoding System
Inventor: SHARPE ANTHONY KEITH
IPC: G08B3/10
Filed: 1983-02-25
Abstract: A pager decoding system which is suitable for use with signal formats, such as POCSAG, in which code words are sent in batches, each batch containing a synchronisation code word and (n-1) address/message code words, n being the number of code words in a batch, each code word comprising m bits. The pager is able to detect or regain a synchronisation code word when the carrier signal is lost due to fading. In a fade recovery mode, (m-1)th, mth, and (m+1)th bit positions are searched to see if a preamble or synchronisation code word is present. If none is detected after a predetermined number of batches has been searched then the pager assumes a loss of synchronisation mode. In this latter mode input data received by the pager is combed through by switching-on the pager for a duration of m bits at intervals corresponding to (n+1) code words. The data received is stored in a shift register 108 having m stages and in which a synchronisation code word can be assembled within two batch periods. Once the synchronisation code word has been detected the pager can be switched to a normal data receive mode. <IMAGE>

Abstract: The apparatus comprises a game board 1 (half of which is shown) with a reticulated surface having areas 2 of a first type, each area representing a supermarket or shop shelf having particular goods thereupon and having a colour-coded value 2a,b,c representing the points value of the goods, and areas 3 of a second type which represent passageways past the shelves; two sets of instruction cards on which a particular word may be highlighted; playing tokens; and a chance device for determining movement of the tokens. A player moves across the areas 3 according to the throw of the chance device, e.g. a die, and may purchase an item from a shelf 2 adjacent the square 3 landed upon, the player accruing the points value of goods purchased. "Final" and "calamity" cards having instructions to a player, and representing advantages or disadvantages of a type encountered in a shop, are selected by a player when landing on a designated area 8. The game ends when a player leaves the shop and the player having the highest number of points wins the game. <IMAGE>

Title: Climbing aid and protection device
Inventor: BANNER HUGH IRVING
IPC: A63B29/02
Filed: 1984-02-09
Abstract: A rock climbing wedge comprises a camnut 1, a tension member 2, 3, 9 and a rotation member 4, 6, 7, 10. A spring 5 which holds the rotation member so that the camnut is normally in a position where its largest dimension is at right angles to the tension member. A downward force on the trigger 8 causes the camnut to assume a position where its smallest dimension is at right angles to the tension member so that the device can be inserted into a crack in the rocks. When the trigger 8 is released the reaction between the force generated by the spring 5 and the tension member pressing against one side of the crack causes the device to wedge securely in the crack. The device will then resist a downward force on the loop 3 but may later be removed by a downward force on the trigger 8. <IMAGE>

Title: Two-stage coal liquefaction process
Inventor: YU GARY SUENMAN
IPC: C10G1/06
Filed: 1984-11-01
Abstract: A process for liquefying coal comprises first forming a coal-solvent slurry in a mixing zone (10). In a hydrothermal dissolving-stripping zone (20) the coal in the slurry is substantially dissolved in the solvent to form a mixture comprising solvent, dissolved coal, insoluble solids and light products, while simultaneously the mixture is stripped of substantial amounts of the light products by contacting the slurry countercurrently with a first hydrogen gas stream at elevated temperatures. A gaseous stream comprising the light products is withdrawn from the hydrothermal dissolving-stripping zone. At least a portion of the mixture containing insoluble solids is contacted in a reaction zone (45) with a second hydrogen gas stream and an externally supplied hydrocracking catalyst under hydrocracking conditions to provide an effluent stream (50) having a normally liquid portion. <IMAGE>
