Title: Improvements in or relating to warning devices
Inventor: SMALLPEICE COSBY DONALD PHILIP
IPC: G08B13/20
Filed: 1959-12-29
Abstract: 915,294. Fire and theft alarms. SMALLPEICE Ltd. Jan. 11, 1961 [Dec. 29, 1959], No. 44064/59. Class 118. [Also in Group XXI] A warning device, for use as a burglar, fire or like alarm, comprises a reservoir 1 containing a fluid at a pressure different from the outside pressure, there being at least one aperture closed by a sealing member 7 connected (e.g. via a pipe system 5) to a wall of the reservoir, the arrangement being such that if a sealing member breaks, a flow of liquid into or out of the system occurs and a pressure-sensitive element 3 connected to a warning means is operated. The sealing member may be made of an inflammable or a fusible material when the device is used as a fire alarm and the fluid in the reservoir (when excess pressure therein is used) can be of a type which extinguishes fires; or for burglar detection, a very fragile sealing member (e.g. at a door or a window) is used and the fluid which escapes when the member is broken can be such as to stupify or mark the intruder. The pressure-sensitive element may be a flexible wall of the reservoir but in Fig. 2 it is shown as a flexible membrane 9 placed over an aperture in a wall of the reservoir and normally it holds a spring-loaded block 10 away from contactsprings 12. When an alarm is to be given, the block moves to the right (excess pressure system) and closes the contacts so that a circuit to a warning bell, lamp &c., is closed and also the membrane may rupture so that a whistle 13 can be operated as an audible alarm by the escaping fluid. In a further embodiment (Fig. 3, not shown) the reservoir is connected through a pipe and collapsible sealing member to a second reservoir of greater capacity which will operate in a similar manner in response to a drop in pressure in the first reservoir.

Abstract: 1,160,529. Rocket launcher; igniters. OERLIKON-BUHRLE HOLDING Ltd. 5 Oct., 1966 [6 Oct., 1965], No. 44500/66. Headings F3A and F3C. A device for securing a rocket 3 in a launcher tube 2 comprises a cap 9 covering the driving nozzle of the rocket and a locking element 8 which may be in the form of a split spring ring. The nozzle body 6 of the rocket is provided with a groove 7 into which the spring ring 8 is forced by the cap 9. The cap 9 is connected by means of rupturable screws 13 to a thrust member 12 to prevent the cap 9 from sliding away from the spring ring 8. A ring 4 is interposed between the rear end face of the launcher tube 2 and a sleeve 5 to form a pair of abutment surfaces 41, 42 against which a shoulder 62 of the nozzle body 6 and the thrust member 12 engage to hold the rocket rigidly within the launcher tube 2 during transportation. A cover may be screwed into the sleeve 5 also during transportation. On firing the rocket propellant charge by an ignition device 10 actuated by a Bowden cable 11 the initial forces exerted by the gas on the one hand on the rocket 3 and hence on the spring ring 8 and thrust member 12 and on the other hand on the cap 9 are balanced so that the rocket remains at rest. At a certain thrust, however, the screws 13 break and the cap 9 slides away from the spring ring 8 which expands away from the groove with the help of the thrust member 12 which is urged thereagainst by the surface 42 to release the rocket 3.

Title: Fastening element
IPC: F16B23/00
Filed: 1973-09-25
Abstract: 1393665 Bolts ELCO INDUSTRIES Inc 25 Sept 1973 [20 Oct 1972] 44813/73 Heading F2H The head 26 of a bolt or screw 25 has in its wrench-engaging portion at least one weakened malleable section 29 of predetermined strength such that when the tightening torque applied by a wrench 30 to the weakened section 29 exceeds a predetermined value, the weakened section is permanently bent so that the wrench slips around the bolt head. Preferably the bolt head is blackened by dipping it in a phosphate, e.g. zinc phosphate, drying it, and dipping it in oil so that the phosphate coating absorbs the oil. When the weakened section 29 is bent at the predetermined torque, it is left bright, thus easing visual inspection of the installed bolt to ensure that it has been tightened correctly. Sufficient of the wrench-engaging portion of the head remains undeformed for the bolt to be loosened or re-tightened subsequently, except in the Fig. 10 and Fig. 13 embodiments. In Figs 1 and 4, a hexagonal head 25a has four chamfered corners 33a and two notched corners 29a. A double-hexagonal wrench 30 is used to tighten the bolt, acting on one weakened corner 29a. At the predetermined torque this corner collapses, Fig. 4, so that the wrench 30 can no longer grip. The bolt can be loosened subsequently, using a hexagonal wrench 37. Two adjacent corners can be notched as 29a to give a higher torque value. Raised symbols 44a indicating the torque value of the bolt are brightened by the wrench on installation. In Fig. 5, a tightening spigot 46b on the bolt head has weakened projections 29b for wrench engagement, these projections being bent (Fig. 7, not shown), at the predetermined torque. Loosening is by a wrench applied to the hexagon portion 45b. A modification, Fig. 8, not shown, has four projections (29c). A further modification, Fig. 9, has a rectangular upper section to the spigot 46d while Fig. 10 shows a variation of this with outwardly flared ends 29e forming the weakened sections. In Fig. 13, a circular head has a recessed central portion 47f bounded by a peripheral wall 31f having wrench-engaging projections 29f which collapse at the predetermined torque. A modification, Fig. 14, has a hexagonal recessed head 26g with corners 29g weakened by holes or thin webs 55g in the body of the head. In Fig. 16, the main portions 31h of the peripheral wall are supported by radial ribs 56h on the bottom of the recess, the corners 29h being unsupported. In Fig. 18, the corners of a recessed head are weakened by being thinner than the main wall portions 31j. A variation of this, Fig. 20, has two weakened corners 29k and four bevelled corners 33k.
