Abstract: 1,171,116. Laminates. E. A. DUFFIELD. 19 Dec., 1966 [18 Dec., 1965], No. 53760/65. Heading B5N. A composite sheet material comprises a basic or board material provided on one or both faces with a composite covering formed from a plurality of laminae, each lamina being of a porous nature and having bonded to it, with a natural or synthetic resin, a mineral powder having a particle size not greater than 50 B.S.S. mesh, the weight ratio of mineral powder to resin being at least 1:1, and the basic or board material and laminae being compressed to an extent such that stratification is removed. The basic or board material is preferably absorbent and may be composed wholly or partially of organic or inorganic fibres, e.g. it may be electrical insulation sheet, hardboard, building board made from organic or inorganic fibres with or without a binder, felted mineral fibres with an organic binder, asbestos cement board, plywood, or chipboard. The laminae may be paper of cellulose or mineral structure, cloth sheet, e.g. textile fabrics and linen, or open weave mineral fabric, e.g. silica or glass fabric or glass fibre sheet. The resin may be Indian lac or a phenolic, epoxy, vinyl acetate polymer, polyester, urea, melamine or silicone resin. In particular thermoplastic resins, e.g. vinyl chloride polymers, polyethylene, polypropylene, polystyrene, acrylic or methacrylic resins, e.g. "Perspex" (Registered Trade Mark) or P.T.F.E. may be used. The mineral powder may be slate, steatite or mica. The composite material may be prepared by treating the basic or board material by roller coating or bath impregnation with a liquid mixture of resin and mineral powder, and placing laminae treated with mineral powder and resin on one or both faces of the basic or board material. Heat and pressure are then applied to bond the layers and cure the resin. If the resin is cold-setting the heat is not necessary. In Example I a hardboard core is roller coated with a liquid mixture of "Bakelite" (Registered Trade Mark) and slate powder and a three sheet laminate of paper coated with the same mixture is placed thereon before bonding and curing by heat and pressure. In Example 2 a partially dried pulp of fibre board, which when dry will form a core of felted mineral fibres, is sprayed with a suspension of powdered slate in urea formaldehyde resin. Resin treated laminae are then applied and bonding, curing and drying effected by heat and pressure. If desired the pressure may be applied in two stages, first slightly whilst melting the resin, and then fully whilst curing the resin. The composite material formed is resistant to fire, water, chemical action and ultra-violet light.

An apparatus for manufacturing structural members 73, such as roof trusses, in which the joints are formed by toothed connecting plates 77, 75, comprises a non-resilient bed 21 for supporting the members and a weight 59 mounted on a movable carriage 67 and arranged to be raised and then allowed to fall freely so as to strike the toothed plates and thereby drive them into the structural members. The carriage 57 is provided with wheels 93 arranged to roll on beams 53 mounted on a structure 37, the latter having wheels 51 for running on tracks 25 secured to the bed 21. The weight is carried by a tube 61 which is slidable on a second tube 63 fixed to the carriage, the weight being raised by means of a chain 115 connected at one end to the tube 61 and, at the other end, to a drum 107. The drum is mounted on a shaft 109 rotatable in the carriage by means of a gear 121 which meshes with a pinion 123 on a shaft 125. The shaft 125 is driven via a clutch 131, by means of an electric motor 133 the clutch being actuated by means of a handle 147. In order to prevent the weight from dropping after it has been raised a flange 155 having internal teeth 157 is secured to the shaft 109 the teeth being arranged to engage with a pawl 159 which is controlled via a handle 167. The bed 21 of the apparatus is formed with grooves (67, Fig. 5) in which are secured wooden strips 65 to which may be secured a jig for locating the roof truss. In operation, after the roof truss elements and the toothed connecting plates have been positioned on the jig, the carriage is moved by means of a handle 103 to bring the weight over a joint. The clutch is then operated so as to raise the weight, the latter being held in the raised position by the pawl 159. In order to release the weight the clutch is momentarily actuated and the pawl moved out of engagement with the teeth via the handle 167. The weight then drops freely on to the toothed plates and drives them into the roof truss.

Title: Pressure regulator for gas supplying gas burners
IPC: F23N1/00
Filed: 1973-11-28
Abstract: 1444739 Valves SOC ITALIANA TECNOMECCANICA LA PRECISA DI DR PEG DE STEFANI SAS 28 Nov 1973 [28 Nov 1972] 55241/73 Heading F2V [Also in Division G3] A pressure regulator for controlling gas supply to a burner has a delayed-opening feature to prevent violent ignition at the burner, the initial gas supply being provided through a variable by-pass 31, 33. The regulator comprises a casing 1 having an inlet 2 and an outlet 3 to the burner controlled by a valve member 9 which may be electromagnetically controlled or controlled by a thermostat. Until this valve is opened a regulator valve 16 remains closed under the influence of a helical spring 17, pressure being equal, because of the by-pass, on either side of the valve and also on either side of a diaphragm 11, to which the valve is attached by a stem 15, by reason of a duct 29 and holes 113 in a cover 13 which provides guidance for the stem. When the valve 9 is opened to ignite the burner the drop in pressure on the upper side of a diaphragm 20, the lower side being vented to atmosphere via a calibrated orifice 30, causes a stem 25 attached to the diaphragm to move, under the influence of a spring 26, towards the other diaphragm 11. Because there is a space between these two members, valve 16 is only opened after a delay and until this has occurred gas flow to the burner is restricted to that which passes through the by-pass throttle 31, 33.

Abstract: 1358090 Detonator firing circuits MESSERSCHMITT - BOLKOW - BLOHM GmbH 29 Nov 1971 [3 Dec 1970] 55379/71 Heading H2H [Also in Division F3] A warhead designed to penetrate the plating of a ship and thereafter fire an explosive charge 7 comprises impact and inertia actuating switches 26a, 26b which when closed allow the capacitor 24 to discharge through a detonating pellet 27 which, after a certain time determined by pyrotechnic composition 28, causes the firing of element 29, piezo-electric firing generators 32 and detonators 12 sequentially; however if hot metal fragments &c. cause a burning of the charge prematurely, the reaction products of the charge, having a higher electrical conductivity than the initial material, short circuit two conductors 9, 10 to allow a second capacitor 25 to discharge through a second detonating pellet 30. There is now no delay in firing the detonators 12 because of the absence of the pyrotechnic composition 28 in the second circuit. If the short circuit resistance of the members 9, 10 is too great to allow a rapid discharge of capacitor 25, a bi-directional thyristor (33) (Fig. 2b, not shown) can be connected in parallel with the members. Alternatively an electronic retardation element (45) (Fig. 3, not shown) may be used to transmit a pulse to a thyristor (47) but on short circuiting of the members 9, 10, a transistor (48) becomes conductive and immediately fires the thyristor (47). The retardation time from closing of the actuating switches to firing of the thyristor may be determined by the time constant of an RC network (Fig. 4, not shown).

Abstract: 1,179,617. Controlling positive clutches. SIEMENS A.G. 15 Dec., 1967 [16 Dec., 1966], No. 56977/67. Headings F2C and F2L. In a positive clutch wherein a lever 10 is pivoted into the path of a cam 8 and abutment 7 on an axially movable driven clutch disc 4 to disengage the clutch and stop the driven disc 4, means 20 are provided to prevent the lever 10 pivoting away from the cam 8 and abutment 7 during a period prior to engagement of the abutment 7 with the lever 10 thus preventing wear due to partial engagement of the abutment 7 and lever 10. The clutch is engaged by energizing an electromagnet 9 which moves an armature clear of the lever 10 and permits a spring 18 to pivot the lever 10 away from the cam 8 and abutment 7 whereafter a spring 11 moves the driven disc 4 into engagement with a continuously rotating driving disc 2. A rod 17 spring pressed into engagement with a cam 15 on the driving disc 2 prevents clutch engaging movement of the driven disc 4 until the clutch teeth are positioned for precise interengagement. The clutch is disengaged by a cam 19 on the driven shaft 6 which pivots the lever 10 into the path of the cam 8 and abutment 7 in which position it is held by the armature of the electromagnet. As shown, a switch 21 in series with the electromagnet 9 is opened for a period prior to engagement of the abutment 7 with the lever 10 by a cam 20 on the driven shaft 6 and thus prevents energization of the electromagnet 9 and pivoting of the lever 10 during the period. In Fig. 2 (not shown), the cam 20 engages a lever (22) which holds the lever 10 in the clutch releasing position during the period.
