Title: Improvements in torpedo suspension gear for aircraft
IPC: B64D1/06
Filed: 1921-07-19
Abstract: 180,591. Purves, R. July 19, 1921. Launching torpedoes.-Relates to apparatus for dropping torpedoes from aircraft, of the kind in which the torpedo is slung in loops round about its centre of gravity, and the nose fan is locked by means of a radius-arm which can be swung up against the aircraft when not in use. According to the invention, the radius-arm comprises telescopic sections 7, 8, which can be adjusted to various lengths and then secured by a pin inserted through one of a number of holes in these sections. This enables the radius-arm to fit torpedoes 22 of different lengths, as shown in full and dotted lines respectively; and also permits the radius-arm to be swung up and down even when the torpedo is in position. The fanlocking member 17 is made rigid with a semicircular clutch 16 and is pivoted by a bolt 21 in the free end of the radius-arm, which is bifurcated to receive a Battened part of the member 17. The other end of the radius-arm is secured to a cross-tube pivoted in brackets 10 on the aircraft and surrounded by one or more coiled springs which, when a torpedo is not engaged, swing the radius-arm up against the fuselage of the aircraft, where it is gripped by a spring clip 14. The radius-arm and the crutch 16 and fanlock 17 are made of oval cross-section. The torpedo is held by slings against crutches 23.

Abstract: 878,464. Extracting pile tubes. SOLER NADAL J. June 18, 1958 [June 26, 1957], No. 19496/58. Class 68(2). Apparatus for forming a cast-insitu concrete pile in which concrete placed in a preparatory tube is compacted by a drop-hammer, is characterized in that part of the energy of the falling hammer is used to rotate a drum which winds in a cable and lifts the preparatory tube, so that tamping of the concrete and withdrawal of the tube proceed together. Fig. 2 shows a plan of the apparatus in which a motordriven pulley 1 drives a pulley 2 through a belt and hence the pinion 3 and a wheel 4 secured to a shaft. A drum 6 is free on the shaft and can be locked to it by a clutch 5, on the drum is wound a cable for raising and lowering the hammer. Secured to the drum is a pinion 7 driving a wheel 8 secured to a shaft which also carries a loose pulley 9 and a clutch member 10, splined to the shaft, which has pegs to engage co-operating holes in the pulley 9. A belt connects the pulley 9 to the pulley 11, secured to a shaft on which is mounted a drum 12. The drum holds the cables which raise the preparatory tube and is driven from the shaft by a pawl and ratchet mechanism which operates only in a direction to wind up the cables. A further drum 16 holds the cable for raising and lowering the concrete bucket and can be driven at will by the sliding pinion 17. When a preparatory tube has been driven to the correct depth a quantity of concrete is placed at the bottom of the tube and tamped with the drop-hammer. During this operation the clutch member 10 is engaged with the pulley so that as the hammer falls the cable attached to the preparatory tube is wound in.

Title: A method of isomerizing alkyl aromatic compounds
IPC: C07C5/27
Filed: 1963-05-16
Abstract: Alkyl aromatic compounds are isomerized by contacting a hydrocarbon charge stock containing a mixture of close boiling isomeric alkyl aromatic compounds, the alkyl groups of which contain from one to four carbon atoms, in the presence of a substantially dry hydrogen containing gas with a reduced acidic carrier based platinum group metal catalyst at a total pressure of from 150 to 500 p.s.i.g., a hydrogen partial pressure of from 125 to 225 p.s.i.g., a weight hourly space velocity of from 0.5 to 5, a ratio of 5 to 20 mols. of hydrogen per mol. of hydrogen charge stock, and a temperature of from 825 DEG  to 950 DEG  F., the hydrocarbon charge stock being substantially free of water and materials producing water under the conversion conditions, whereby catalyst isomerization activity and selectivity are maintained at a high level.  The mixture of isomeric alkyl aromatic compounds may be deficient in at least one isomer. Preferably, the water content of the total feedstock is maintained below 50 per million parts by volume of total feed in the vapour phase and the water content of the effluent withdrawn from the reaction system is maintained below 50 per million parts by volume of total effluent. Starting materials used may be of the benzene or naphthalene series e.g. a C8 fraction containing 1 to 30 vol. per cent ethyl benzene, 1 to 30 vol. per cent o-xylene, 10 to 30 vol. per cent p-xylene and 40 to 88 vol. per cent of m-xylene.  The catalyst consists essentially of 0.1 to 2.0% by weight of a platinum group metal e.g. platinum, palladium, rhodium and iridium, supported on alumina or magnesia containing at least one acidic component e.g. silica, boria, zirconia or mixtures thereof. The examples describe isomerization of hydrocarbon mixtures containing less than 100 parts of water by volume per million parts of feedstock, and in Example 2 the feedstock contains 96.8 volume per cent ethyl benzene. Specifications 735,390, 837,907, and 951,344 are referred to.

Title: Device for controlling the process of petroleum desalination and dehydration in electric dehydrators
IPC: C10G33/08
Filed: 1975-05-10
Abstract: 1497610 Automatic control systems RYAZAN FILIAL SPETSIAIL KONSTRUKTOR BJURO PO AUTOMATIKE V NEFTEPERERABOTKE I NEFTEKHIMII 10 May 1975 19748/75 Heading G3R [Also in Division C5] In a process in which crude petroleum is mixed with water for subsequent de-salination and de-hydration by an electric current between electrodes 6, 7 energized from a transformer 9, the ratio of petroleum to water is controlled by adjusting the water flow in response to the amplitude and frequency of current pulses which occur just prior to electrical breakdown. It is desired to operate the process at a point close to, but safely short of, electrical breakdown. The pulses are detected by differentiating at 10 a signal corresponding to electrode current. The output of 10 is applied to graded threshold devices 11 1 ...11 n  whose outputs are connected to pulse counters 12 1 ... 12 n . 11 1  and 121 are set at the desired magnitude and frequency (i.e. number of pulses in a time set on a timer 13), and the others at progressively higher values. If the pulses are below all the thresholds a "setting pulse generator" 14 is operated which, via a frequency divider 15 and controller 17 increases the water flow in steps via control loop 18, 20, 21 until the threshold of 11 1  is exceeded. This inhibits 14 so that no further change takes place. However, if the thresholds of 11 2 -11 n  are reached a "negative correction device" 16 is activated to decrease the water flow, in steps, at a rate determined by how many thresholds have been exceeded.

Title: Electrical protection system
Inventor: MUEHTER MANFRED WOLFGANG
IPC: G08B29/08
Filed: 1960-06-07
Abstract: 892,198. Electric alarm systems. AMERICAN DISTRICT TELEGRAPH CO. June 7, 1960, No. 19967/60. Class 118. In an alarm system in which a direct current of predetermined value normally flows in a transmission line connecting a substation to a central station and changes in the value of this current are detected at the central station, an oscillator is provided at the substation which transmits an A.C. signal of predetermined amplitude over the line to the central station where an increase or a decrease in the value of the A.C. is detected. The invention is described as applied to a burglar alarm system. The D.C. arrangements are conventional and the change from night to day protection is effected by opening contacts 27, 70 and 75 and closing contacts 83, 84 and 85 so that the protection devices 71, 73, 79 and 80 and the door contacts 72 are rendered inoperative. In the night condition, breaks and grounds operate the central station drop 15 in the usual manner to actuate the alarm circuits 16. In order to detect attempts to tamper with the system by bridging the line 11, 12 with a resistance approximating to that of the protection circuits, a Colpitts oscillator 17 including a transistor 21 is provided at the substation and continuously transmits over the line 11, 12 an A.C. signal which is amplified by the push-pull transistor amplifier 40 at the central station, rectified and applied to " high " and " low " relays RH and RL, the gain of amplifier 40 being adjusted by means of taps 50, 51 so that RL is normally energized and RH de-energized. If, due to tampering, the A.C. signal amplitude falls, RL falls away and the closure of contacts RL1  lights lamp 63, energizes the auxiliary winding RHX of relay RH to bring up RH which locks, and operates RA to sound the buzzer BZ. The central station operator then operates switches 61 and 64. The buzzer is thus silenced, RHX and RA are de-energized and lamp 63 is connected directly across the D.C. supply. If the tampering produces an increase in the A.C. signal, RH will pull up with similar results. Testing.-The operator opens switch 89 and closes switch 90 to connect reverse battery to the line 11, 12. This normally energizes the bell coil BC and its contacts BC1 interrupt the circuit, the ringing of the bell indicating to the subscriber that the system is in working order. In addition the current induced in the secondary winding of transformer 95 lights the neon lamp 98.

Abstract: 635,751. Fluid-actuated valves. SMITH, E. G. G., and MASTERS, P. D. Dec. 4, 1943, No. 20303. [Class 135] In a cut-out valve for a fluid-pressure line, the fluid flows in at B, past a restriction 10, through grooves 11 in a piston assembly 8, Fig. 1, and out through a port A. The inlet fluid is applied through a passage 12 to the top of the member 8 and the outlet fluid is applied through a passage 13 to the underside thereof on which a spring 9 also acts. When a drop of pressure occurs on the outlet side, as, for example, on the breaking of the fluid line, the fluid pressure will be removed from the underside of the piston 8 and the inlet pressure acting on the top will move it downwards to shut off the flow. In a modification, a ported, sliding sleeve 14, Fig. 5, surrounds the piston 8 which latter is provided with two grooves 11. In the open position, both sleeve and piston are forced to their uppermost position by outlet fluid pressure against the action of loading spring 16. When a fall of pressure occurs on the outlet side, inlet pressure applied through apertures 18, 19 forces the sleeve downwards but keeps the piston 8 in its upper position, as shown. In a further modification, a separate loading spring surrounding spring 16 is applied to the top of sleeve 14.
