Title: Scoring device for the game of bridge and other card games
IPC: A63F1/18
Filed: 1932-08-08
Abstract: 383,245. Scoring-apparatus for games. CROUSSE, L., 6, Rue Rougemont, Paris. Aug. 8, 1932, No. 22194. Convention date, Jan. 28. [Class 132 (ii).] A scoring device for bridge and other card games comprises a board 1 having numbered holes 2 into which are inserted pegs, the pegs being threaded upon elastic strings 10. The board is divided into three divisions, the first one T for scoring tricks, the second H for honours and the third R for players' points. Divisions T and H have two rows of holes designated E and N, signifying " they " and " we." Division R has four rows, marked A, B, C, D, one row appertaining to each player. A cube 15, threaded on the righthand string 10, is marked with the letters N, AB, AC, AD to remind the scorer (who is designated A) of the composition of the sides. The pegs used in divisions T and H are singleended, but those in division R have two differently-coloured ends for indicating winnings and losses respectively. Divisions H and R are provided with cubical or hexagonal members 13, 14 threaded on the strings 10 and used for indicating the thousands digits in the scores. Pegs 5 and holes 3 in the first division T register the number of games won. The ends of the strings are held in beads fitting in recesses in the underside of the board.

Abstract: 730,792. Moulding pre-stressed reinforced concrete. BRUCE, R. Sept. 7, 1953 [Sept. 8, 1952], No..22491/52. Class 87 (2). When moulding lengths of pre-stressed concrete in taut metal shuttering, the shuttering is tensed alternately at each end so as to keep it in movement relative to the concrete and prevent it adhering thereto. The mould has a base 11 with recesses 19 to receive the longitudinally tautened shutterings 12 which subdivide the mould longitudinally and may be stretched in alternate directions by jacks 17a, 18 a applied to members 17, 18 to which the shutterings are attached. The shutterings may be lowered into the recesses 19 after moulding by hydraulic jacks 20. The pre-stressing wires 13 are tensioned by jack 16. The lengths may be subdivided by threading pre-cast soft concrete spacing elements on to the wires these members being broken after moulding to expose the wires which are then severed.

Abstract: 1467257 Burner for waste gas disposal BRITISH PETROLEUM CO Ltd 24 April 1974 [11 May 1973] 22572/73 Addition to 1303439 Heading F4T A flare burner receives high pressure fuel gas, e.g. excess refinery waste gas or liquid petroleum gas, via line 4. The gas is discharged over a director surface 5, 6 which utilizes the Coanda effect to deflect the gas towards the zone of combustion of liquid fuel issuing from an atomizer nozzle 11. The gas flow over the surface 5, 6 also induces movement of the surrounding air towards the combustion zone and this enables a non-smoky flare to be obtained. Moreover, secondary air is drawn along passage 7 towards the combustion zone. The burner may be mounted vertically or horizontally.

Abstract: 360,366. Washing gases. SNOW, N. L., New Canaan, Connecticut, U.S.A. Aug. 1, 1930, No. 23266. [Class 55 (ii).] Dust is removed from gases by a staggered arrangement of flat-sided baffles of appreciable width or thickness over the entire surface of which liquid flows downwards. The baffles 22 are of rhomboid section,and disposed vertically in a casing having a tank 20 at the top, and a sloping bottom 18 leading to a valve-controlled liquid outlet. The baffles may be of square, oblong or octagonal section, and may be hollow.. Nozzles 38 in the tank bottom deliver to troughs formed between the bevelled tops of the baffles, Fig. 3, and flanges 35 secured to them and having serrated upper edges between which liquid flows down the baffle faces. The troughs and the spaces between the teeth are kept clean by liquid jets delivered through nozzles 42, 43 from conduits 44, 40. Fig. 12 shows a modified arrangement of liquid supply in which the baffle tops extend upwards through the tank bottom and spring-pressed plates 91 limited by stops control the liquid flow.

The remote control protective system of the parent Specification in which a motor B supplied by means of a trailing cable V ... Z is controlled by a circuit having a threeposition switch G, a half-wave rectifier m, and a relay k with a coil k<SP>2</SP> shunted by a large capacity condenser n, is modified in that when the switch is in the "running" position r<SP>3</SP> the rectifier m is connected in parallel with the resistance p<SP>1</SP>, Fig. 2 (not shown) or is replaced by a second rectifier m<SP>1</SP> in parallel with the resistant p<SP>1</SP>, Fig. 1. It is stated that when the switch is in this running position, the excitation of the relay coil k2 is reduced, as much of the increased current in the control circuit is alternating and passes through the condenser n which has a low impedance relative to that of the relay coil. The excitation is also reduced due to the resistance p<SP>1</SP> providing an additional discharge path for the condenser during the half cycles in which the rectifier is non-conducting. With these arrangements, the resistance of the control circuit is reduced when the switch is in the running position so that the system may be made more sensitive to increases in resistance in the earth connections.

In an example, four mols of formaldehyde, 12 mols aniline, 8 mols of HCl and 50 mols of water were mixed and heated to 90 DEG C. to produce 4, 41-methylenedianiline, to which 10 mols caustic soda were added and the mixture heated to 90 DEG C. and allowed to settle into two layers, which were separated.  To the upper layer containing crude methylenedianiline, dissolved in monochlorobenzene, was added phosgene in monochlorobenzene, and more phosgene was introduced whilst the mixture was heated to its reflux temperature.  After 5 hours the resulting clear solution was refluxed for 15 to 30 minutes, purged with nitrogen for 2 hours at 110 DEG  to 120 DEG C. and then clarified by filtration at 80 DEG C. The clarified solution was stripped of monochlorobenzene in vacuo and the residue distilled through a 15cm. Vigreaux fractionating column to collect a product fraction boiling between 185 DEG  and 188 DEG C/4mm. absolute mercury pressure.
