Title: Disturbance detection systems
IPC: G08B13/12
Filed: 1973-06-11
Abstract: 1441583 Intruder alarms INERTIA SWITCH Ltd 14 June 1973 [15 June 1972 11 June 1973] 28165/72 and 27675/73 Heading G4N [Also in Division H3] A disturbance detector comprises a sensor circuit 10 including normally closed contacts IS1-IS5 actuated by the disturbance and normaly open contacts C actuated by a disturbance of greater magnitude, means providing an output signal upon actuation of normally closed contacts for an adjustable period and means providing a second signal if the open contacts are closed. In operation, vibration resulting for example from hammering or sawing causes pulsating current to be applied to an integrating circuit 29-35 and when the voltage across capacitor 35 exceeds the threshold voltage of a Zener diode 45 it fires an SCR 49. This short circuits a normally operated relay RLA and thus operates an alarm 64. Closing of the normally open contacts by a larger disturbance, e.g. opening a door, operates, via a second circuit including transistors 25, 55 and a Zener diode 61, also to fire the thyristor 49 either immediately as shown or after a delay. A reset for circuit 37-41 discharges the integrating circuit when the sensing circuit is not producing a signal. A switch S1 may be thrown e.g. during a low risk period, so that the diodes 17, 19, 21, 23 are reverse biased and the alarm sensors associated therewith removed from the circuit. In Fig. 3 (not shown), which is particularly for use in monitoring a chain link fence, the circuit responds to the appearance of a predetermined number of output signals in a given time. Fig 4 further includes means for distinguishing continuous alarm signals caused by vibrations not associated with attempted entry. A pulse rate counter 85 determines whether sense pulses are received at a rate greater than a predetermined value and generates a signal to disable a gate 87 and hence activation of the alarm 83 via elements 71-75. In addition, if the output signal from 85 continues for more than the period of a time 69, a further counter 89 generates an output signal a predetermined number of which are counted by counter 91 before activation of the alarm 83 via another gate 93.

Title: Improvements in or relating to members to be used in heat engines
Inventor: SECH YVES LE
IPC: F01D5/28
Filed: 1948-10-26
Abstract: 656,503. Turbine blades. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Oct. 26, 1948, No. 27846. Convention date, Oct. 27, 1947. [Class 110(iii)] [Also in Groups II and XXII] A member capable of withstanding mechanical stresses at high temperatures such as a gas turbine blade, a combustion chamber for a heat engine, a hot gas pipe &c. is characterized in that a metal core a is coated at least on its exposed surface with alternate adhesive refractory layers of enamel c and metal m<SP>1</SP>, m<SP>2</SP>. In one embodiment a gas turbine blade comprises a core a and root t of highly refractory alloy, e,g. nickel-chrome austenitic steel. The core, after pickling the surface, is coated with nickel m<SP>1</SP> by electrolytic deposition and the nickel coating is covered with a layer e of zirconium oxide enamel enriched with other refractory oxides, e.g. molybdenum oxide, vanadium oxide, tungsten oxide. The layer e is deposited by atomization and then baked and glazed with a zirconium oxide enamel minus the refractory oxides. Finally, the layer e is covered with a layer m<SP>2</SP> of chromium deposited by electrolytic means. The enamel layers increase their refractory properties by the inclusion of 'larger proportions of refractory. oxides the further they are from the core a. At the root t the metal layer m<SP>2</SP> adheres directly to the core a thereby forming a closed heat conducting circuit. To improve,. adhesion of the layers e and m<SP>1</SP>, fritted enamel, crushed without the refractory oxides but charged with nickel and bismuth ions, may be sprayed on the layer m<SP>1</SP> at the beginning of the atomization. The term " enamel" includes glass, glassware glaze, metal enamels, ceramic varnish, enamel or glaze, ceramic paste or a mixture of these compositions. The enamel layers may be applied with a brush, or by spraying, or by powdering with a blower or by lithographic printing. The metal layers may be iron, chromium, nickel, cobalt, platinum or other refractory metals or alloys or metals in combination with non-metals. The metallic layers may be deposited by plating methods such as electrolysis, chemical displacement and the like.

Title: Improvements in and relating to winch gear for hauling, cargo working and like purposes
IPC: B66D1/22
Filed: 1936-10-14
Abstract: 477,641. Winches. GENERAL ELECTRIC CO., Ltd., and MACFARLANE, G. T. Oct. 14, 1936, Nos. 27876 and 34413. [Class 78 (v)] A winch-drum 6 carried loosely on a shaft 11 has a gear wheel 26 meshing with a pinion 27 fixed on a parallel lay-shaft 9. The drum 6 is driven by the shaft 11 through an epicyclic gear comprising a sun-wheel 12 fixed to the shaft 11, planet wheels 14 carried by a cage 15, and an outer ring 20 fixed to the drum itself. The cage 15 is bolted to a gear-wheel 17 meshing with a pinion 19 loose on the shaft 9 but rigid with the drum 30 of a hoisting brake. The shaft 9 carries at one end a oneway holding and lowering brake 28, and medially the sliding male member 35 of a clutch, the female member 36 of which is rigid with the pinion 19. For hoisting the brake 30 is applied, thus holding the pinion 19 and the cage 15 fixed, and allowing the shaft 11 to rotate the drum 6 with a two or three to one reduction. When the power is taken off, the one-way brake 28 holds the load, which can be lowered by loosening the band of brake 28. For forcing down an empty hook, the member 35 of the clutch, normally held open by a counterweight, is closed against the member 36 to lock the shaft 9 to the pinion 19. Both brakes 28 and 30 being off, the shaft 11 then through the wheel 12 and planets 14 rotates the wheel 17 and thus turns the drum 6 through pinions 19, 27 and wheel 26 at a high speed in the reverse direction. Interlocking means for preventing the brakes, clutches, &c. being operated in the wrong sequence consists of a hand-wheel 40 which reciprocates a slide 42 through pinion and rack 44, 43. A projection 45 extending from the slide 42 forces aside a crank lever 47 which effects slackening of the brake 28 against the on-pull of a weight 52. Further movement of the slide 42 in the same direction brings a second projection 46 against a lever 55 which inserts the clutch member 35 through a link 54 against the off-pull of a weight 56. Return movement of the slide 42 first declutches members 35 and 36, then applies the one-way brake 28, and finally through projection 45 moves a crank lever 48 to apply the hoisting brake 30. The brake 30 may be arranged to slip with excess load to protect the motor. The brake 28 may be a twodirectional one, the levers 47, 48 and 55 being then so intercoupled that the brake 28 is automatically released as the brake 30 is applied and vice versa, it being also independently releasable. The provision of the lay-shaft 9 permits smaller sized brakes and clutch, and the layout is stated to permit of ready conversion of existing winches. A warp end 10 rotates with the drum 6. Specifications 477,608, 477,641, and 477,655 are referred to.

Title: Improvements in or relating to telephone signalling systems
Inventor: VRIES WILLEM CECIL DE
IPC: H04B3/20
Filed: 1947-10-17
Abstract: 648,848. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Oct. 17, 1947, No. 27889. Convention date, June 15, 1946. [Class 40 (iv)] False operation of signal receivers in tandem - connected telephone systems employing voice frequency signalling is prevented by signal suppressors consisting of valvecontrolled variable attenuation networks which reduce the level of the signals transmitted from one system to another before the unwanted signal receivers have time to respond. As shown in Fig. 1, 4-wire systems I and II employing signalling currents of the same voice frequencies are interconnected by a system III using a different signalling frequency. A signal suppressor 13 connected in the incoming circuit of system III and controlled by voice frequency signals transmitted from a contact 1 in system I operates and attenuates the signals transmitted to systems III and II before a signal receiver 8 in system II has time,to respond. Signal receiver 2 subsequently responds and disconnects the outgoing speech circuit of system I at contact 3. A signal suppressor 14 provides identical control of signals from system II. Fixed attenuators 0.8 are provided between each system. The signal suppressors may alternatively be connected either in the incoming circuits of systems I and II (Fig. 2, not shown), or in both incoming and outgoing circuits. When different frequencies are used for signalling in opposite directions (Fig. 3 and 4, not shown), the signal suppressors are made responsive to both frequencies to provide control of signals which may be fed back in the opposite direction by way of an unbalanced hybrid coil. To prevent undue attenuation of speech, the signal suppressors may be associated with series and shunt connected band-filters so that only a narrow speech band is attenuated. Alternatively, guard circuits may be provided for the signal receivers or suppressors to render them inoperative if the signal frequencies are associated with other frequencies. Specification 489,545 is referred to.

Title: Processing of synthetic and cellulosic fibres
IPC: D06M11/38
Filed: 1946-09-18
Abstract: Combination yarns, i.e. yarns spun from a combination of natural cotton and alkali-insoluble artificial fibres such as cellulose acetate, nylon and the like, are immersed in a 22 per cent solution of caustic soda at 75-80 DEG  F. for 1 1/2 -2 minutes, washed, neutralized and dried.  The term "yarn" is used to cover strands (twisted or untwisted), threads, cloth and other fabricated materials.  The yarn, with or without tension, may be immersed in a bath or vat whence the yarn passes through squeezing rollers before being neutralized, preferably with acetic acid.  If desired, it may be passed prior to immersion over gassing burners. Loose ends or "fuzz" on the yarn are removed by this process. Softening agents may be included in the neutralizing bath.

Title: Improvements in or relating to amplifier circuit arrangements
IPC: H03F1/54
Filed: 1956-09-14
Abstract: 810,109. Valve amplifying and alarm circuits. SPERRY RAND CORPORATION. Sept. 14, 1956 [Sept. 20, 1955 (2)], No. 28154/56. Class 40 (6). A push-pull amplifier comprises two channels each fed from a separate power supply and having two valves in cascade, an input transformer common to both channels having a split secondary winding and negative feedback to each channel via a current limiting resistor from a centre tapped resistor connected across one of a plurality of secondary windings on a common output transformer. As shown, an alarm circuit 9 may be provided to indicate the failure of any channel of a number of such amplifiers. The two channels comprising respectively valves 11, 12 and 13, 14 are fed from the input transformer 19 and are coupled to an output transformer 53. The voltage from winding 56 is reduced by the tapped resistor 30 before being fed back to the input in series with resistors 26, 29 and the input transformer secondary windings. The first stage anode circuits are shunted by capacitors 37, 38 to prevent H.F. oscillation due to output transformer leakage inductance. Resistors 26, 29, connected between the secondary windings and the grids, prevent short circuit of the input to one stage in the event of grid circuit breakdown in the other. Resistors 54, 55, in series with the output transformer, prevent damage to the H.T. supply or short circuit of the output signals in the event of anode circuit breakdown in either output stage. Resistors 54, 55 should be twice the value of the anode impedance of one valve. Degeneration due to the omission of cathode by-pass capacitors is overcome by regeneration between the cathodes of each stage by resistors 59, 60. Fig. 4 shows an alternative interstage coupling wherein a centre tapped inductor 71 is connected across the grid circuits of the output stages so that failure of either input stage does not affect the drive to either output stage. Resistors 72, 73 prevent short circuit of the drive to one output stage in the event of grid circuit breakdown in the other. Alarm system.-A frequency F2, ten times the normal input frequency F1, is fed from the low impedance oscillator 8 via the feedback circuit to both channels in phase. No output at F2 is normally present because of cancellation in the output transformer 53, but loss of gain in either channel will result in an output component at F2 which is selected by the circuit 98, 74 (resonant at F2) and amplified by the valve 76. The voltage at the anode of valve 76 is rectified by rectifier 86 to provide a negative voltage to cut off valve 84 and release relay 88 which opens the circuit of the metertype indicator 93, thus allowing the warning flag 96 to swing into line with the window 97. Fig. 7 shows how the alarm may be connected to n complete channels. Cn, which represents the total parallel capacity, is made to resonate with the inductor 74<SP>1</SP> at frequency F2.

Inventor: TAYLOR ANTHONY JAMES
IPC: G21D5/08
Filed: 1957-09-06
Abstract: 837,786. Nuclear reactors. BABCOCK & WILCOX Ltd. Sept. 4, 1958 [Sept. 6, 1957], No. 28279/57. Drawings to Specification. Class 39(4). In a nuclear reactor safety system for a ship propulsion plant, flow of coolant carbon dioxide from the reactor to the heat excharger is automatically cut off by an isolating valve at the reactor when the piping connecting the reactor to the heat exchanger is damaged thereby limiting the loss of fluid from the reactor. In one embodiment, damage is detected by tubes containing gas slightly above atmospheric pressure which are laid along the outer surface of the coolant piping so that rupture of the latter and hence also the tubing, produces a drop in pressure therein which operates the isolating valve control system. The tubing may be arranged longitudinally or spirally about the pipes. Alternatively, the tubing may be formed as a sleeve round the pipes. The valve control system may be responsive to the rate of charge of pressure in the tubing. Drainage may also be detached electrically by an insulated wire wrapper round the piping. If the wire is fractured or brought into contact with the piping by damage to the latter, the isolating valves are operated.
