Title: Improvements in electrical alarms
IPC: G08B13/22
Filed: 1953-08-25
Abstract: 750,437. Theft alarms. BYRNE, J. N. April 30, 1954 [Aug. 25, 1953], No. 23409/53. Class 118(1) A theft alarm comprises a housing, such as a case, through which a spring-loaded plunger 7 can protrude thereby completing an electric circuit which may be within the housing or at a separate location, the plunger being depressed within the housing and the circuit opened when the housing is placed on an object, so that on lifting the housing the electric circuit is completed thereby energizing a selfholding relay controlling the operation of an alarm device, such as an electric buzzer, bell or other visual or audible signal device. The alarm is so constructed that movement of the housing on the object also causes the completion of the circuit so that the alarm is operated. Once the alarm has been operated it continues in operation whatever the position of the plunger until the circuit is broken by means of a key-operated control switch within the housing. The plunger comprises a rod 7 carrying a conical protuberance 8 which is urged downwardly by means of a compression spring 10. The rod passes through the wall of the housing so that on lifting the housing the protuberance 8 is free to move downwardly and complete a circuit through the rod 7 and a contact plate 12. If the housing is moved without being lifted from the object on which it rests, the rod 7 will move with respect to the plate 12 and complete the circuit by making contact with the edge of the aperture in the plate through which it passes. A number of alarms may be interconnected, so that operation of any one causes the operation of all of them. Instead, the alarm may be connected to one or more slave devices which also give an alarm signal when the housing for the alarm is moved. In the preferred embodiment, the alarm circuit is arranged within the housing; in an alternative arrangement the housing comprises the plunger and associated contacts only, and is connected to one or more slave alarm devices.

Title: Improvements in or relating to internal combustion engines having two crankshafts and employing superchargers
IPC: F02D23/02
Filed: 1939-08-17
Abstract: 533,644. Fluid-pressure servomotor systems. SULZER FRERES SOC. ANON. Aug. 17, 1939, No. 23717. Convention date, June 7. [Class 135] [Also in Group XXVII] In internal-combustion engines having two crank shafts with separate banks of cylinders to the two shafts, and at least one supercharger to each bank of cylinders, fuel-control apparatus is arranged to be acted upon by a speed governor and also by a pressure-responsive device arranged to be subject to that supercharging-pressure of the two which at any moment is the lower. Fig. 4 shows the fuel pumps 8 and 8<SP>1</SP> of the two banks of cylinders controlled by arms 34, 34<SP>1</SP> on rods 30, 30<SP>1</SP>, which are connected together by arms 32, 32<SP>1</SP> and a lever 33, and are further connected to a speed governor 50 through a resilient device 51, and to servomotors 11, 11<SP>1</SP> subjected respectively to the pressures delivered by the two super-chargers. These pressures are admitted by pipes 31, 31<SP>1</SP> to the spaces above diaphragms 12 connected to the valves 14 of servomotor pistons 16 which carry stops 18, 181 limiting the amount by which the fuel supply may be increased. Thus the stop 18 or 18<SP>1</SP> corresponding to the super-charging-pressure which is the lower brings about a corresponding reduction in the fuel supply, by acting on an arm 22 or 22<SP>1</SP> on the rod 30<SP>1</SP>. The governor 50 also controls a servomotor 27 adjusting a resistance 24 in circuit with a generator 25 driven by the engine, so as to keep the load on the engine constant. In modifications, the two diaphragms 12 may be arranged in the same casing and connected to a common servomotor; or the two super-charging- pressures may act on opposite sides of the same diaphragm. In another form, having four super-chargers each supplying half of the cylinders of a bank, four diaphragms subjected to the four pressures respectively are arranged to act directly on the fuel-pump controls, the controls of opposed half-banks being connected together.

Abstract: 854,902. Machinery guards. PROJECTILE & ENGINEERING CO. Ltd., GASPAR, E., and SWINBOURNE, G. K. Aug. 7, 1957; [Aug. 7, 1956], No. 24215/56. Class 80 (4). In an injection moulding or like machine, wherein a guard 17 is horizontally movable on bars 15, 16 by a piston-rod 22 of a fluidpressure system interlocked, by means not shown, with the movable platen 13 of the machine to ensure a sequential operation of the guard and platen, the guard 17 carries flexible means such as a trip wire 30 so that should the guard-closing be obstructed (e.g. by an operator's arm) the wire 30 is deflected and actuates means to stop the guard. As shown, the wire 30 extends between a bracket 31 and a spring- loaded lever 27 carrying a pawl engageable with a fixed rack 25. In a modification the lower end of the wire 30 is attached to a friction clip, Fig. 2 (not shown), holding a pawl suspended above a fixed rack, deflection of the wire causing the' clip to open and drop the pawl into engagement with the rack. In a further modification the trip-wire 30 is connected to a switch or valve controlling the guard-closing cylinder 23. The cylinder 23 is controlled by a solenoid-operated valve 24. In the machine shown the platen 13 is moved by an hydraulic ram towards a fixed platen 14 provided with plasticizing and injection mechanism. Operation of a push-button causes closure of the guard 17 which when closed operates a valve to start the closure of the platen 13. In turn, the closing platen operates a valve to start the injection process. After injection, and if necessary after a time delay, the platen 13 and guard 17 commence to open, the guard movement being slowed by an air restriction so that the platen is fully open before the guard. When the guard is fully open it connects the pump of the platen hydraulic supply to exhaust.
