Title: Improvements in or relating to submarine mines
IPC: F42B22/10
Filed: 1923-08-22
Abstract: 226,262. Vickers, Ltd., and Elia, G. E. Aug. 22, 1923. Mines, marine.-Relates to submarine mines of the kind in which an auxiliary float is attached to the main mine and rises therefrom to a given depth when the mine is launched, for example as in Specifications 218,334 and 221,530. According to the invention, (1) the auxiliary float is released from the main mine by means of a delay-action device, such as a soluble plug, or a dashpot, or an hydrostat, after the main mine has become moored to its appointed depth; and (2) means, such as used in automatically mooring a main mine at a given depth, are provided for stopping the auxiliary float at a given depth irrespective of the depth of the main mine, for example an hydrostat adapted to stop a drum after the latter has been released by a soluble plug to pay out an extra length of line connecting the auxiliary float to the main mine. As shown in Fig. 2, the auxiliary float 1 has a bracket 12 formed with a hole 11 which is fitted over a pin 10 on a bracket 9 fixed to the main mine 2. The auxiliary Boat is provided with an hydrostat 6, the stem 5 of which fits into a hole 4 in a bracket 3 fixed to the main mine. When the main mine is sunk to its appointed depth, the spring 8 of the hydrostat is overcome by the pressure of the water and the stem 5 is withdrawn from the hole 4, thereby releasing the auxiliary float from the main mine. As shown in Fig. 3, the upper end of the cable connecting the auxiliary float to the main mine is connected to an extra length of line 16 wound on a drum 15 in a casing 14 carried by the auxiliary float. When the auxiliary float rises from the main mine, a line 21a attached to the man mine pulls a rubber cap 20 off a projection 21 on the casing 14, thereby uncovering a soluble plug 22. This, when dissolved, releases a spring plunger 24, which unlocks the drum 15 and releases another spring plunger 27; and this latter plunger in turn releases the stem 28 of an hvdrostat 29. When, now, the auxiliary float reaches the desired depth, a spring 31 overcomes the hydrostatic pressure and pulls the stem 28 to the right, bringing a recess therein in line with balls 32, which thereupon release the abutment 33 of the spring 31. This abutment is then driven back by its spring and forces spring plungers 34 into engagement with lugs 37 on the drum 15, thereby stopping the drum and holding the auxiliary float at the desired depth. Spring friction brakes 39 control the speed of the drum 15. Auxiliary contact firing devices, for example such as described in Specification 221,530, may be arranged on the various cables and on the auxiliary float.

Title: A fluid pressure indicator
Inventor: BILLINGTON EVANS R
IPC: G01L7/08
Filed: 1955-07-11
Abstract: 811,916. Pressure indicators. BASTIANBLESSING CO. July 11, 1955, No. 21339/57. Divided out of 811,915. Class 106 (2). A fluid-pressure indicator comprises a body 20 connected to a pressure source by a passage 25, a resilient diaphragm 28, a bonnet 30 clamping the diaphragm in place and having a window 34 therein, a signal element 50 movable in response to movement of the diaphragm 28 to move across the window 34, a spring which urges the diaphragm 28 and signal element 50 in one direction, the diaphragm 28 being mounted to snap in one direction or the other when the pressure reaches a critical point, and a screw 41 for varying the compression on the spring without altering the position of the signal element 50. The diaphragm 28 is clamped between the base 20 and the bonnet 30, which has windows 34 on opposite walls. Resting on the diaphragm is a cup member 50 of green plastic, into which telescopes an inverted cup member 43 of red plastic, the cups being held apart by the spring which is supported in the bonnet against upward movement by a flange 42 and threads into a nut 44. The bonnet 30 is covered by a transparent hood 36, the thread 37 of which permits restrictive communication with the atmosphere. In the position shown the indicator is in the warning position with the diaphragm in its lowermost position since it is subject to a pressure lower than the critical value. In this position the red cup 43 is visible through the windows 34. When the pressure rises above the critical value, the diaphragm which is of larger area than the recess 26 which it covers, snaps over and raises the green cup 50 to cover the red cup 43 and be visible through the windows. In a modification the nut 44 is made integral with the upper cup 43. The indicator is described in combination with a domestic liquefied petroleum gas dispensing system, such as that described in Specification 811,915.

Title: Fire alarm system with monitoring device for fire alarms connected in groups to a central station
Inventor: WALTHARD BEAT
IPC: G08B29/14
Filed: 1967-05-09
Abstract: 1,140,294. Fire alarm systems. CERBERUS A.G. 9 May, 1967 [9 May, 1966], No. 21516/67. Heading G4H. A fire alarm system comprises a central signal station to which individual fire alarm devices are connected in groups, the number of conductors being independent of the number of devices in a group, and testing means are provided by which alarm conditions are simulated in the fire alarm devices to produce a binary signal from each, the binary signals being received by an evaluation device in such a way that monitoring of the responses from individual devices is independent of the number in a group. Each fire-alarm device consists of a pair of ionization chambers 1, 2 Fig. 2 of which one, 1, detects the presence of combustion gases and the other provides a reference. The junction between them is connected to a switching device e.g. a field-effect transistor 3 connected between conductors 10, 20 which pass to the central station 18 having a voltage source Ub. When combustion gases enter chamber 1 the resistance changes and transistor 3 conducts causing a voltage drop on resistor 5 sufficient to ignite SCR 6. Current passes through Zener diode 15 and indicating lamp 12, or resistor 13 if the lamp is defective. The change in current in conductors 10, 20 operates a relay A at the central station. The voltage drop necessary to operate transistor 3 can be produced for test purposes by reducing the potential on line 10. This may be done by introducing a Zener diode 8 into the circuit by opening switch 7. The lower voltage prevents Zener diode 15 igniting so that current flows only through the resistor 14. The current is much smaller than the normal alarm current and relay A does not respond but the secondary winding of transformer 11 passes a pulse to the counter 19. The alarm devices in a group are arranged by capacitor 9 to have different response times so that the pulses arrive sequentially and are counted. The count indicates whether all the alarm devices in the group have responded. The system is reset by switch 16. In a modification (Fig. 1, not shown), a sequential response of the alarm devices is achieved by a serial connection of the several devices so that only if the first responds to the test signal can the second respond and so on. A relay shows that the last device has responded or a counter indicates as before that all devices have responded or shows the number of the defective device. In another modification each alarm device has an oscillator which oscillates until the device responds, when the oscillations are suppressed. The several devices are connected by way of an Or gate the output of which indicates whether or not all the devices have responded.

Abstract: 665,790. Pencil holders. HARVEY, J. H. Aug. 18, 1949, No. 21517/49. Addition to 645,241. Class 146 (iii). The invention relates to an improvement in or modification of the magazine pencil described in the parent Specification and especially concerns the mounting and actuation of the chuck. The magazine or magazines are arranged between a hollow cap 6 and a tubular member 21 connected together by a tubular member 16, the member 21 having a lead passage 23 leading to a chuck comprising jaws 32, 33, 34. These jaws carry ribs 35 slidable in grooves 31 in a tubular tapered member 30, and are supported by a spring ring 27 secured to the end of a member 22 slidable in the member 21 screwed to a member 13. As shown, there are two rotatable magazines 1, 2 such that the particular lead to be fed therefrom is brought into alignment with the inlet 24 of the passage 23 and the lead is allowed to drop on to the top of the chuck. An actuating member 37 connected to the member 23 by a rod 38 is then depressed against a spring 48 to permit the jaws 32, 33, 34 to move forward and so open out to allow the lead to drop through until the desired projection is obtained. When two magazines are employed one compartment of the lower magazine is left empty to allow leads from the upper magazine to pass through into the passage 23. The casing of the magazines may be transparent, or provided with external markings indicating the colour of the leads in each compartment.
