IPC: A61K31/275
Filed: 1959-11-18
Abstract: A therapeutic preparation for the treatment of mental diseases comprises 2-amino-1,3,3-tricyano-2-propene dispersed in or dissolved in a pharmaceutically acceptable carrier.  The preparations are preferably administered in unit dosage forms such as tablets, capsules, pills, powders, packets, granules, wafers, cachets, sterile parenteral solutions or suspensions, or oral solutions or suspensions.  For solid compositions e.g. tablets, adjuvants such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums are used.  The tablets or pills may be laminated, the inner dosage component being separated from the outer by an enteric layer consisting of materials such as polymeric acids or mixtures of polymeric acids with shellac, shellac and cetyl alcohol or cellulose acetate.  A particularly useful enteric layer contains styrene maleic acid copolymer with other known enteric materials. Specified liquid forms are aqueous solutions, flavoured syrups, aqueous or oil suspensions, flavoured emulsions with edible oils such as cottonseed, sesame, coconut or peanut oil and elixirs. Suitable suspending agents for aqueous suspensions are synthetic or natural gums, e.g. tragacanth, acacia, alginate, dextran, sodium carboxy methyl cellulose, methyl cellulose, polyvinyl pyrrolidone or gelatine.  In aqueous preparations antioxidants may be included, e.g. 0.1% ascorbic acid or 0.1% of a sulphur containing reducing agent, e.g. sulphur dioxide, sulphur containing acids which may yield sulphur dioxide, soluble non-toxic salts of such sulphur containing acids or aldehyde addition products thereof.  The preparations may contain other medicaments such as tranquilizers, e.g. reserpine, chlorpromazine, promethazine benactyzine, ectylurea, imipramine, or meprobamate; sedatives, e.g. phenobarbital, pentobarbital or amobarbital; analgesics, e.g. aspirin, phenacetin, salicylamide or N-acetyl-p-aminophenol; stimulants, e.g. amphetamine, cleanol, pipradol, methyl phenidyl or improniazed; Vitamins A1, D1 B,1, B2, B6, B12, pantothenate, folic acid or nicotinamide; and hormones e.g. oestradiol or methyl testosterone.

Title: Hydraulic device for a reciprocal motion subject to load reversal
Inventor: BERG FRITZ
IPC: F15B13/01
Filed: 1957-12-19
Abstract: 872,471. Hydraulic machines. KRANBAU EBERSWALDE VEB. Dec. 19, 1957, No. 39424/57. Class 69 (2). A differential piston 5a for driving a load subject to reversal, e.g. the jib of a crane, is driven by a reversible pump 1 connected in a closed system, an auxiliary pump 8 compensating for the difference in effective area of the two sides of the piston 5a. The pump 8 maintains the system filled with oil at a predetermined pressure controlled by a valve 9 by way of valves 10, 11. When pump 1 is supplying line 2, pressure fluid passes through valve 17 to chamber 7 to move piston 5a to the left, and over line 12 forces the piston 15 of valve 13 to its left terminal position (shown) whereby fluid displaced from chamber 6 is passed by valve 13 over line 3 to the suction side of pump 1. During this operation pump 8 supplies oil to the suction side of the pump 1 via valve 10. Should the load on the piston-rod 5 reverse, the consequential drop in pressure in chamber 7 and line 12 causes piston 15 to be moved to the right by spring 14 to throttle the flow of oil from chamber 6 to line 3 and thus brake the piston 5a until the pressure in chamber 7 and line 12 builds up to move valve piston 15 to the left to remove the braking action on piston 5a. When pump 1 is supplying line 3, pressure fluid passes via line 19a and a valve 16 to chamber 6 to move piston 5a to the right, whereby oil is returned to the suction side of pump 1 over line 2. At the same time, pressure fluid via line 19 moves the piston 20a of valve 17 to the right so that the excess oil displaced from chamber 7 is passed over line 18 back to a reservoir 22. Should the load on the piston 5a reverse, the piston 20a is moved to the left by spring 21 and the valve 17 throttles the return of oil over line 18 to brake the piston 5a. Two or more working cylinders may be used with their pistons 5a connected hydraulically in parallel.

Title: Improvements in or relating to gas turbines
IPC: F02C5/12
Filed: 1929-12-24
Abstract: 347,245. Gas turbines. MARGONI, C., 22, Via Roma, Trieste, Italy. Dec. 24, 1929, No. 39484. [Class 110 (iii).] The combustion chambers 9, 10 of a gas turbine are opened automatically to a pressure chamber 5 when ignition occurs by valves 15, 16 actuated by pistons 27, 28. Gases remaining in the chambers 9, 10 after discharge are passed by automatically operated valves 19, 20 to an exhaust 18, and may be used in the low pressure turbine 3. The turbines 2, 3, arranged on separate shafts 4, 41, have duplicate sets of blades so that they may be reversed. They are controlled by ported valveplates 38. If the pressure in the chamber 5 becomes excessive, a pressure-responsive device 45 interrupts the ignition. Turbines 8 driving auxiliaries may be supplied from the chamber 5.

Title: Improvements in and relating to transistor circuit arrangements
IPC: H03K4/72
Filed: 1962-10-19
Abstract: 1,013,006. Transistor sawtooth circuits. PHILCO CORPORATION. Oct. 19, 1962 [Oct. 19, 1961], No. 39628/62. Heading H3T. A sawtooth generator comprises a switching transistor 70 connected in series with the base/emitter path of an amplifying transistor 22, the transistor 70 passing a current having a curved characteristic during the forward stroke, the characteristics of the amplifier circuit being such as to provide a linear sawtooth current in a deflection yoke 30. The rising current in the primary winding 16 of a blocking oscillator induces a voltage in the secondary 84 which is fed via a differentiating capacitor 120 to maintain transistor 70 conductive until it is no longer saturated, when the base current decreases, producing a regenerative cutting- off of the transistor 70 and hence transistor 22. The duration of the flyback is determined by the oscillatory circuit 16, 34, 76, 162. The frequency is controlled by resistor 88 and the amplitude by resistor 76. A beam-blanking pulse may be obtained from transformer 152 in the collector circuit. Figs. 1, 5 (not shown) relate to simplified versions in which the yoke 30 is connected in series with the collector of transistor 22. Linearizing.-The rising current in transistor 70 is linearized by the reduction in beta in input impedance of transistor 22 as the base current increases. Further linearizing is achieved by negative feedback via capacitors 140, 144, 148 and resistors 142, 146. Synchronizing.-In television apparatus, vertical synchronizing pulses may be derived from the synchronizing signal by an integrator 126 and are fed to the blocking oscillator transistor 70 via a gating diode 122 which is biased off by a waveform fed via capacitor 134 during the forward stroke so as to eliminate spurious pulses in the synchronizing signal.

Inventor: HOWARD DONALD WARNER
IPC: F16D66/00
Filed: 1971-08-27
Abstract: 1312209 Brake lining indicators BENDIX CORP 27 Aug 1971 [11 Sept 1970] 40229/71 Heading F2E An assembly for indicating the wear and temperature of a vehicle brake friction lining comprises a temperature responsive element in thermal communication with the lining and spaced fiom a probe associated with an electrical circuit connected to an indicator remote from the brake and spaced from the surface of the brake friction lining, whereby the element electrically connects the probe to the brake backing-plate to actuate the indicator to provide a signal when the lining temperature reaches a predetermined value. A bi-metallic strip 40, comprising a metal, 48, of higher coefficient of expansion than that of a metal 46, contacts the probe in the form of a wire loop 28 on one side 32 when the line reaches a certain temperature. The bimetallic strip 40 is earthed through the lining 14 of a disc or drum brake and causes a control device 50 to operate a lamp 56. The wire loop 28 also provides wear indication in that when the lining 14 wears a predetermined amount, the loop end 37 contacts the brake disc 12, which is earthed, and operates the lamp 56 during brake application only. Further lining wear causes the loop end 37 to be broken and causes the lamp 50 to operate continuously.

Filed: 1961-11-10
Abstract: 933,538. Ventilators. FORD MOTOR CO. Ltd. Nov. 10, 1961 [Nov. 14, 1960], No. 40288/61. Class 137. A ventilator assembly includes a frame with an opening therein, a closure member for the opening, and means supporting the closure member in a manner allowing movement between open and closed positions, the closure member being allowed to tilt relative to the supporting means, independently of the opening and closing movement, about more than one axis, so that in its closed position the former may seat in a coplanar relationship with the frame opening. As shown, the frame 12, which is preferably formed as a single casting, has a flange 13 by which it may be secured to a heater or air conditioning system, with a resilient gasket 15 to seal the joint. The frame 12 has an air inlet 16 and a louvred outlet 17. The closure member or door 19 is supported by a crank shaped member 20 which pivots in bushings 21 in the frame 12 and may be operated through a cranked arm 36. A resilient layer 23 on the door 19 provides an air seal when the door is closed. A clip 25 secured to an embossed centre portion 24 of the door 19 has a C-shaped section enclosing the member 20, and touching the latter only at an indented portion 27 (Fig. 5). Thus the door 19 has three degrees of rotational freedom relative to the member 20, through angles limited by tabs 28, 29, 31, 32, 33, on the door, the tabs having slots wider than the member 20, thus compensating for irregularities between the mating surfaces of the door and frame. One or more of these slots may have resilient inserts, e.g. 34, 35, to reduce wear and noise.

Abstract: 1373863 Alarm circuit for inflatable safety system ALLIED CHEMICAL CORP 31 Aug 1972 [2 Sept 1971] 40438/72 Heading G1A [Also in Divisions G4 and H2] A supply circuit for an inflatable safety system in a vehicle (see Division H2) includes a lamp 44 which is illuminated for a few seconds whilst a capacitor 40 is charged from a battery 14. The lamp 44 illuminates a light activated silicon controlled switch 56 which therefore short circuits a lamp 60. When the capacitor is fully charged the lamp 44 is switched off but the switch 56  continues to short circuit the lamp 60, the extinction of which indicates to the vehicle driver that the circuit is functioning correctly. In a modification a photo-cell (70), Fig. 2a (not shown) receives light from the lamp 44 and controls an S. C. R. connected across a light emitting diode. Alternatively the lamp 44 heats a thermistor (90), Fig. 2b (not shown) which controls an S. C. R. connected across a further lamp. The lamp 44 may be replaced by a light emitting diode.

Abstract: 1,188,847. Electric correspondence control systems. HONEYWELL Ltd. Sept. 5, 1968 [Sept. 8, 1967], No.41128/67. Heading G1N. [Also in Division G3] In a process control system comprising two or more control stations 1, 2 each having a manually adjustable potentiometer 3, 3a for generating a set point signal and means 11, 11a for indicating the value of the set point signal, manual adjustment of the set point potentiometer at any one of the stations causes a corresponding adjustment to be made at each other station to maintain the values of the set point signals generated at all the stations equal. As shown in Fig. 1, each station has a servomotor 19, 19a which is normally used to drive an indicator 25, 25a for indicating the value of the process variable being controlled, but when, for example, a wheel 12a at station 2 is depressed ready to adjust potentiometer 3a, a switch 27a is closed thereby energizing a coil 29 in station 1 to change a switch 17 from the position shown in full lines to the position shown in dotted lines and also energizing a further coil 31 in station 1 to operate a clutch to lock together the wheels 4 and 21 so that when the wheel 12a is turned to adjust potentiometer 3a, servomotor 19 operates to adjust potentiometer 3. A controller 33 receives the process variable signal from terminal 14 and the set point signal via switch 36 from one of the control stations and delivers an amplified error signal which is used for controlling the process variable concerned. Each control station may also include a further servosystem, Fig. 2 (not shown), for indicating the value of the control signal and a switch (66, 66a) enabling a bumpless change to manual control using the balancing potentiometer (60, 60a) of the further servosystem as a transmitter. During manual control, a feedback circuit keeps the output of controller 33 equal to the control signal generated by the manual control so that change back to automatic control is bumpless. Interlocks and warning lights are provided to prevent manual operation from two stations simultaneously. Plug-in connections may be provided between the control stations and a junction box 48. Several controllers 33 may be provided, each connected through a respective junction box 48 to a single control station, and a second control station may be plugged in at will to any one of the junction boxes 48.
