Abstract: 562,071. Electromagnetic vibrationmeasurers. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 5, 1943, No. 1927. Convention date, Feb. 11, 1942. [Class 40 (iv)] A device for generating a voltage proportional to the vibration velocity of a vibrating body comprises a shell of magnetizable material rigidly connected to a magnet, the polepiece of which conforms to the interior of the shell to form between it and the shell an air gap in which is situated a coil wound on a former, the magnetic structure and the former being connected by a resilient suspension including inner and outer ring portions, one of which is attached to the magnetic structure and the other to the former, the rings being connected by a W- shaped spring comprising two pairs of long and short upright members connected at their upper ends respectively to the outer and inner rings and connected together at their lower ends by yoke pieces, as shown in Fig. 5. As shown in Fig. 1, the device comprises a cylindrical shell 11 of magnetizable material supported by end plates 12, 13 which carry also a centre rod 15 on which are mounted a cylindrical permanent magnet 16 and polepieces 17, 18. A cylindrical coil former 44 carries two coils situated in the gaps between the polepieces and the shell 11, and is carried at each end by a suspension member 36, 37 of the form shown in Fig. 5. The member comprises an outer flanged ring 39 secured to the coil former, an inner ring 38 clamped between washers mounted on the rod 15, and long and short vertical spring arms 40, 42 connected at their upper ends respectively to the outer and inner rings and connected together by yokes 41 at their lower ends. When the springs 40 are deflected by the relative movement of the coil former and magnet system the weight of the former acting on their upper ends acts against the restoring force of the springs and so lowers the natural frequency of the system, so that stronger springs may be used. The former 44 carries a check pin 50, the end of which is flush with the outer surface of the end plate 13 when the former is correctly adjusted. The electrical circuit to the coils is made through the suspension members 36, 37, the latter being connected to one of the output leads by a conducting sleeve 24 on the rod 15. Damping between the shell and the coil former may be introduced by the use of damping fluid in the shell. In use, the base 53 of the device is secured to the body, the vibration of which is to be measured.

Title: Operation recorder for motor vehicle safety device
IPC: B60R21/16
Filed: 1972-12-12
Abstract: 1360360 Crash restraint bag NISSAN MOTOR CO Ltd 12 Dec 1972 [9 Feb 1972] 57264/72 Heading B7B The correct operation of a crash restraint bag is recorded by a memory device 15 fed with signals S4 by a coincidence circuit 13, fed with signals S2 by a collision sensor 10 through a gating circuit 11 and with signals S3 by a sensor 14. The sensor 10 is responsive to a collision condition of a vehicle, e.g. it may be a mass of magnetic material normally abutting a magnet but moved, due to rapid deceleration upon a collision, to engage two contacts. The gating circuit 11 generates a signal S2 of a predetermined time duration of the order of 10 to 100 milliseconds, i.e. longer than the time required for the crash bag to be actuated. The sensor includes comparators 32, 33 connected at points (a) and (b) respectively. When the voltages at points (a) and (b) become 12 and zero respectively, due to destruction of detonation element 21, the comparators 32 produce outputs fed to a NOR gate which applies a true "1" signal S3 to an AND gate. If a true "1" signal is also applied to the AND gate by the gating circuit 11 a true "1" signal is applied to a transistor 41 to burn out an electric fuse 40, thus indicating a malfunction, i.e. operation of the bag prior to collision or at a time greater than a predetermined time after a collision. If on the other hand, correct operation ensues, the signals at the AND gate are not synchronized such that the transistor 41 is not energized. The sensor 14 may alternatively be a pneumatically controlled switch opened and closed in response to pressure in a container for storing pressurized gas, a conductive wire adapted to be broken upon actuation of the safety device, or an electric or mechanical switch capable of sensing expansion of the gas bag.

Filed: 1970-12-11
Abstract: 1337999 Phosphides SONY CORP 11 Dec 1970 [13 Dec 1969 (4)] 59080/70 Heading C1A [Also in Division B1] A phosphide is made by feeding inert gas into a reaction zone containing a phoaphideforming material and a solid or liquid source of gaseous phosphorus, and maintaining the gas at a pressure at least equal to the decomposition pressure of the phosphide; heating the reaction zone sufficiently to vaporize at least a part of the phosphorus source at a pressure about equal to the pressure of the inert gas inside the reaction zone; and heating the phosphideforming material to a temperature sufficient to react with the phosphorus vapour, while simultaneously maintaining an upper part of the reaction zone at a temperature below the inversion temperature of liquid phosphorus to red phosphorus such that an atmosphere of gaseous phosphorus is formed below, and in equilibrium with, an atmosphere of inert gas. In one embodiment (Fig. 3), a hollow watercooled condenser 7 is located above crucible 10 in a quartz reaction chamber 5 provided with inlet 5A for inert gas, and heater 11. In operation, red phosphorus or stable liquid phosphorus 8 is vaporized by heating the reaction chamber to about 430‹ C. The condenser surface 7A is maintained at a temperature above the melting point of yellow phosphorus (44‹ C.) but below the temperature of inversion to red phosphorus (250‹ C.) so that drops of liquefied yellow phosphorus 12 return to the heating zone and an atom atmosphere of yellow phosphorus vapour at constant vapour pressure is established at the same pressure as the inert gas 6. The vapour pressure of the phosphorus can be controlled by changing the pressure of the inert gas. A Group III element, e.g. In, Ga, or a mixture of the element and pre-formed phosphide is placed in crucible 10 in which phosphide synthesis or monocrystalline growth occurs. The condenser 7 is formed of a metal non- reactive to phosphorus e.g. Al or Ti. In further embodiment (not shown) the reaction chamber is open-topped and enclosed in a pressure vessel filled with inert gas, with the condenser in the form of a coil or annular chamber. The crucible may be movable in and out of hot zone provided by an annular graphite heater inside the reaction chamber and surrounding the crucible. Monocrystals, e.g. gallium posphide are made in apparatus in which, e.g. (1) gallium phosphide is precipitated from molten gallium held in a crucible along which a temperature gradient is maintained (see Division B1); (2) a monocrystal, formed on a seed fixed on the end of a rod is pulled from a melt.

Abstract: 1359139 Automatic voltage and current control JOSEPH LUCAS (INDUSTRIES) Ltd 6 Dec 1971 [15 Dec 1970] 59573/70 Heading G3R Battery testing apparatus includes a current regulator for controlling charge and discharge of the battery. To change over from charge to discharge operation, or vice versa, gating signals are removed from a conducting thyristor, the current regulator is set to zero so that the thyristor turns off, and a second previously blocked thyristor is gated on. In the circuit shown, a battery 23 is charged from a mains transformer 11 and rectifier bridge 14-17 through an ammeter 38, resistor 37, parallel transistors 31-33, diode 25 and thyristor 21. The voltage across resistor 37 is compared with a reference voltage 45 to vary the conduction of a transistor 44 which in turn controls transistors 31-33 to regulate the charging current. To switch to a discharge mode, a relay is operated, causing contacts 52 and 55 to open, cutting off gate current to thyristor 21 and reducing the current regulator reference voltage to zero, so that the thyristor 21 blocks. A contact 54 now closes, and contact 52 recloses in its alternative position, so that the reference voltage 45 is reconnected and a thyristor 26 turns on to provide a discharge path for the battery through diode 18, anmeter 38, resistor 37 and transistors 31-33. In a modification, Fig.2 (not shown), a voltage regulator circuit, including a Zener diode and transistors, may be connected in the gating circuit of thyristor 21 so that the battery is charged at constant voltage by controlling the firing angle of the thyristor.
