Patent GB-131659-A (GB)
IPC: B64D17/52
Abstract: 131,659. Smith, E. E. July 16, 1918. Parachutes.-The load falling upon a parachute first pulls it from its casing in a partlyopened condition, so that it falls rapidly until sufficient velocity has been acquired and the aviator has drawn well clear of the machine; the pressure then operates to withdrawn locking-pins, which are mounted upon pivoted bars, and the parachute fully expands. The rigging-cords may be separately wound to avoid entanglement. The parachute is mounted upon a frame 1, Fig. 1, and enclosed in a covering 2 with a readily removable end 3. Tabs or " spools " 6, upon which the fabric is partially wound up, are held by pins 9 entering holes 8, but are released when the parts 9, 13 rock upon knifeedges 12 to a sufficient extent. Cross-connexions formed by springs 15, 17 and ties 18 ensure simultaneous operation of the catches, which takes place when the partly-opened parachute exerts sufficient drag to deflect the springs 15, 17 by a predetermined amount. Each cord 19 is coiled upon a mandrel by winding a few turns alternately in opposite directions, and then placed in a separate pocket. In a modification, Fig. 5, the pins 10 are placed upon the spools 6, and engage holes in segmental bars, hinged upon a part 20, release being effected by rupture of a retaining-band 23. A further modification, Fig. 7, includes pivoted bars 9 bearing pegs 10 which fully release the parachute when cords 23 are broken by the force of the air-drag, or released by a slipping spring bolt. The rigging-cords are coiled within a basket 22.

Abstract: 691,462. Burglar alarm systems. RELY-ABELL BURGLAR & FIRE ALARM CO., Ltd. May 11, 1949 [May 14, 1948]. No. 13341/48. Class 40 (i). [Also in Group XXXIX] A subscriber's line testing and alarm device arranged in association with a burglar alarm system in which a warning message is transmitted to an emergency telephone number, comprises a line testing relay 17 which causes the operation of a local alarm if the line is either engaged by an incoming call or is disconnected, separate tests being made for an A.C. ringing signal and the presence ot U.C. current trom the exchange. As shown, an alarm signal on lead M operates relay 1 which connects relay 17 to the telephone line L through a condenser 18. At the same time a clockwork or electric motor 7 driving cams A and, B is started. If A.C. ringing current is present on the line, relay 17 will pull up and complete a circuit from a local battery 31 for a relay 26, which locks when operated and controls an alarm bell 32. After an A.C. test of two seconds duration, cam A disconnects the operating circuit of relay 26 while cani B connects the telephone line directly to relay 17 for the D.C. test and transfers the released contacts of this relay into the operating circuit of relay 26. Cam A then releases its contact for a short period and the alarm bell is operated unless relay 17 has been pulled up by D.C. exchange current. In a modification shown in dotted lines on the figure, the line testing relay is shunted by a half wave rectifier 20 for the ringing test, the rectifier being subsequently disconnected for the D.C. test. The resistance of the line testing relay should be sufficiently low to enable the exchange equipment to be seized, and this resistance may be lowered if necessary by a second winding (not shown) which is connected in parallel with the relay winding by contacts which are closed when the relay pulls up. Switching means (not shown) may be provided to disconnect the motor after one revolution of the cams.

Abstract: 315,943. Marks, E. C. R., (Grasselli Chemical Co.).. May 12, 1928. Cadmium and its alloys, depositing.-A bright deposit of cadmium is obtained by the use of a bath containing a cadmium compound and a predetermined relatively small amount of a compound of cobalt, nickel or copper. For very small amounts of the added metal, e.g. in the case of nickel 0.001-0.03 per cent of the weight of the bath, the effect is catalytic, the deposit containing no trace of the added metal, but when larger amounts are used, e.g. up to 0.10 per cent of nickel, the added metal is present in the deposit. The bath also contains a small amount, e.g. 1 per cent, of an organic addition agent such as sulphite cellulose waste, sulphonated vegetable oils, the water-soluble products of caustic alkali treatment of non-cellulosic vegetable matter, dextrine, starch, protein materials, alkaline extracts or solutions of wool and albumen. A suitable organic addition agent may be made by treating sulphite cellulose waste liquor or an aqueous solution of dry sulphite cellulose waste with an alkali metal salt having an alkaline reaction, e.g. sodium, potassium or ammonium carbonate, alkali metal phosphates or sodium silicate to remove calcium, magnesium and heavy metal compounds. A suitable bath composition consists of 120 gms. sodium cyanide, 48 gms. cadmium hydroxide, 60 gms. sodium sulphate, 1.5 gms. crystallized nickel sulphate, and 12 gms. Turkon oil dissolved in 1 litre of water. Cadmium anodes are employed; the current density may be 20 amps. per sq. ft.
