Title: Improvements in or relating to vehicle suspension systems
Inventor: ARMSTRONG WILLIAM
IPC: B60G15/08
Filed: 1956-11-09
Abstract: 820,556. Spring suspensions; pneumatic springs. ARMSTRONG PATENTS CO. Ltd. Nov. 4, 1957 [Nov. 9, 1956], No. 34238/56. Classes 108(2) and 108(3) A vehicle suspension system comprises a torsion bar T, Fig. 4, in combination with a hydropneumatic strut S. Inner member I, Fig. 1, carrying piston 50 slides in outer member O guided by member 30. As these members move towards each other air or other inert gas P is compressed by oil H. The oil and air may be in contact as shown or separated by a floating piston or a flexible diaphragm. Valves 21, 22 control the flow of oil through piston 50 to provide damping. Members 27, 47 are attached to sprung and unsprung portions of the vehicle. Fig. 4 shows the strut S applied to a " wishbone " front wheel suspension incorporating a torsion bar T. The strut is also described and illustrated as applied to front and rear trailing link suspension systems and a rear swinging arm suspension system all of which employ torsion bars. By providing an oil pump, a reservoir and a distributer unit, the amount of oil in the struts may be controlled to vary the riding characteristics of the vehicle.

Title: Electric fan
IPC: F16P3/12
Filed: 1969-07-09
Abstract: 1,271,244. Electromagnetic brakes; machinery safety devices. MATSUSHITA SEIKO CO. Ltd. 9 July, 1969 [25 July, 1968; 14 Oct., 1968], No. 34549/69. Headings F2E and F2J. [Also in Divisions G1, H2 and H3] The invention relates to stopping an electric fan when the guard is touched or approached, and is described particularly with reference to a single-phase induction motor braked by connecting D.C. to the stator and simultaneously actuating a mechanical brake integral with the motor or impeller. Various combinations of sensor circuits, electrodynamic braking, and mechanical braking are described Figs. 1 ... 26 (mostly not shown). Sensor circuits.-(i) Fig. 8 (not shown) a grid leak biased valve oscillator is damped by approach of body to energize a relay (ii) "hum pick-up" from the body touching guard is amplified, e.g. to control a supply thyristor Fig. 2 or electromagnetic relay Figs. 11, and 14 ... 18 (not shown) Figs. 14 and 15 incorporating a flip-flop and a trigger circuit (iii) pressure sensitive resistors may be used between the guard and the motor. Electro dynamic braking.-Generally a sensor controlled relay opens to leave a half-wave rectifier in series with the motor Figs. 5, 8 and 14 ... 16 (not shown)-(Figs. 14, 15 happen to show a motor with an auxiliary tapped variable speed winding). However in Fig. 18 (not shown) the relay changes over to a reverse winding, and in Fig. 2 transistor 19 gated by diode 21 conducts on alternate half cycles to block triac 15 so that half-wave D.C. is applied to the motor. (Further the diode 13 supplying the brake solenoid 9 blocks these D.C. pulses, permitting application of the mechanical brake 7 by tension spring 8.  Mechanical braking.-Many embodiments, Figs. 3, 4, 6, 7, 12, 13, 19 ... 22 and 25, 26 (not shown) use a pin and inclined slot connection between the impeller and the rotor to provide axial motion forcing the rotor against the endplate (protected by friction materials) when electrodynamic braking occurs. In Figs. 21, 22 and 25, 26, the impeller engages the end plate. Alternatively a solenoid-operated brake may be used co-operating with a disc on the shaft, Fig. 17 (not shown), or rubbing on the impeller boss Figs. 23, 24 (not shown) or a spring- operated, solenoid-released disc may rub on the rotor Figs. 9, 10 (not shown). This latter brake has to be reset if it is released.

Title: Improvements relating to the recuperation of hydrochloric acid gas from aqueous hydrochloric acid
IPC: C01B7/01
Filed: 1927-12-21
Abstract: 307,985. International Sugar & Alcohol Co., Ltd., (Soc. Industrielle de la Cellulose). Dec. 21, 1927. Hydrochloric acid.-In preparing hydrochloric acid gas from aqueous hydrochloric acid by heating with calcium chloride, the residue of calcium chloride is subjected to reduced pressure, whereby water is distilled and the temperature is reduced ready for use again. Aqueous hydrochloric acid of 30 per cent strength is heated with calcium chloride solution containing not more than 40 and preferably 30 parts of water to 100 parts of calcium chloride. Hydrochloric acid gas is evolved and passed through a cooling coil to separate water. The bulk of the acid passes off before a temperature of 130‹ C. is reached. The temperature is further increased to 165‹ C. when a dilute aqueous hydrochloric acid distils over. The heating is stopped and the residue subjected to vacuum, when water distils over, and a residue containing 30 parts of water to 100 parts calcium chloride, and at a temperature of about 70‹ C. is obtained.

Title: Control and measuring system for high voltage electric power transmission systems
IPC: G01R15/14
Filed: 1966-08-03
Abstract: 1,121,719. Protective systems. S. & C. ELECTRIC CO. 3 Aug., 1966 [20 Oct., 1965], No. 34778/66. Heading H2K. [Also in Divisions G1, H1 and H4] A protective or measuring arrangement for a high voltage conductor 10 comprises a radio transmitter 25 operating at the potential of the conductor and modulated by a variable, e.g. current, of the conductor to transmit a signal to a radio receiver at a remote point at earth potential. As shown, the transmitter 25 is mounted within a shunt 20 formed by a cylindrical resistance member 21 within a coaxial cylindrical conductor 23, the voltage across the member 21 being proportional to the current in the conductor 10 on which the shunt is mounted. This voltage is applied through a modulation control circuit 31 to modulate a frequency modulated oscillator 26 connected between metal end caps 29, 30, which act as an antenna and serve as corona shields. The power supply for the transmitter is derived from the conductor 10 through a saturable core transformer 37 and a power supply circuit 36 which includes a relay which renders the transmitter operative when the current reaches a predetermined minimum value. The transmitted signal is received by an amplifier and mixer 45 where the signal beats with the output of a crystal oscillator 46 to provide an intermediate frequency which is applied through a crystal filter 47, an intermediate frequency amplifier 48 and a further filter 49 to a demodulator and squelch circuit 50. This circuit provides a mains frequency output signal when a relay operates after a short time delay sufficient to ensure that a reliable signal is being obtained. The output signal is applied through a low-pass filter 51 and amplifiers 52, 18 to a relay 15 to effect the tripping of a circuitbreaker 11 when the signal is of sufficient magnitude. The signal is also applied to a current responsive device 17, e.g. an ammeter, a current element of a wattmeter, a watthour meter or a power factor meter or a recording oscillograph. Reference is also made to the use of the arrangement when the variable is the potential of the conductor, a stress variation or a vibration of the conductor.
