Title: Improved means for preventing premature opening of vessels under pressure
IPC: F16J13/24
Filed: 1943-09-01
Abstract: 568,282. Pressure - resisting covers. CHEERS, F. L., and MERCER, S. Sept. 1, 1943, No. 14236. [Class 123 (i)] In a device for preventing the opening of a cover on a vessel until the internal pressure, positive or negative, has been released, a locking gate a used to retain the cover, e.g. of a pressure cooker, is pivoted at i and carries a plate b adapted to be interlocked with a pressure release valve h. The plate b is slotted at k, the slot terminating in a recess which extends only partly through the plate. The spindle of the valve h carries a plate c having the central part l removed to accommodate the nut f, the plate being of such dimensions as to rotate freely in the recess j, and when rotated into position, to slide along slot k. It is necessary for the valve to be rotated to open position to bring the plate c into line with the slot k, and thereby to allow the parts a, b to be rotated about their pivot i to open the cover. The valve may alternatively be attached to the moving gate, and the slotted plate b may be fixed.

Title: Method of reducing the rate of wear of refractory walls
IPC: C21C5/44
Filed: 1972-03-27
Abstract: 1366725 Preserving furnace walls CREUSOTLOIRE and E SPRUNCK 27 March 1972 [30 March 1971 20 Oct 1971] 14248/72 Heading F4B The rate of wear of a refractory furnace wall is reduced by applying a carbon-donating substance to the wall in fluid or paste-like form adapted to cause the deposit of carbon particles on the wall. The substance used may contain carbon or coal particles or it may be a hydrocarbon such as fuel oil or heated tar sprayed on to the wall by pressurized nitrogen or hydrocarbon gas. The liquid hydrocarbon is cracked by the heat of the furnace wall to deposit carbon. The substance used may be painted on to the wall instead of being sprayed. In a converter, Fig. 2, the carbon-donating substance is applied the wall by one or more lines of tuyeres 6, 9, 12, 15 passing through the wall at spaced points and sprayed against the wall opposite. Oxygen is supplied through tuyere 5 for refining. The amount of carbon-donating substance applied to the walls of the converter may be more than the amount theoretically sufficient to ensure zero wear of the wall. The refractory materials of the wall may be initially impregnated with a carbon-donating substance, e.g. tar.

Title: Improvements in or relating to switches for electric flash light apparatus
IPC: H01H53/12
Filed: 1926-06-07
Abstract: 270,507. Woosnam, A., (Svenska Aktiebolaget Gasaccumulator). June 7, 1926. Electromagnetic interrupters; contacts; springs, arrangement of; switches, actuating. - The electromagnet of flash light switching apparatus acts on an armature mounted directly on the oscillatory shaft of a momentum device which is operated in one direction by the electromagnet and in the reverse direction by a stressed spring, and a yieldably mounted connection transmits motion from the shaft to at least one of the pair of contacts which makes and breaks the flash light circuit. The balance shaft 4 carries a swinging mass 17 and balance spring 3 which is adjustably secured to the shaft and also to an arm 14, adjustably fixed on a sleeve 22. A second spring 10 is adjustably fixed to the shaft and also to an arm 6 loose on the shaft, the arm carrying a contact 7 which is urged against a fixed contact 8 by the spring 10. On closing the circuit to an elecromagnet 1, the armature which is adjustably fixed on the shaft rotates the latter and causes an arm 11 to engage the arm 6 and separate the contacts 7, 8, thus breaking the circuit. The shaft, however, under the influence of the mass 17, continues to rotate until the tension spring 13 arrests and returns it, so re-closing the contacts 7, 8 and re-energizing the electromagnet 1 to repeat the cycle. Shock and vibration on closure are reduced by the spring 10 and sparking is consequently reduced, and the period of the cycle is regulated by adjustment of the springs 10, 13. In another form, the arm 6 does not carry the contact 7 but moves it independently against spring action, and in a further form the contact 7 is mounted on a spring-controlled lever and moved by a cam on the shaft. The mass 17 may have a stop 19 to limit its travel, and instead of the balance member 17 a swinging pendulum or reciprocating armature might be used.

Filed: 1972-05-04
Abstract: 1365009 Electro-depositing aluminium SIEMENS AG 4 May 1972 [7 May 1971] 14313/72 Heading C7B An A1 coating is applied to a shaped article formed from a metal attacked by aqueous or protic media or oxygen to form (hydr)oxidic or salt coating, e.g. Zr, Nb, Ta, W, Be, Mg, Zn, Al, Ti or alloy thereof, by providing the shaped article with surfaces free from the coating in the presence of an inert anhydrous aprotic liquid covering the surfaces, and, without exposing the surfaces to an aqueous or aprotic medium or oxygen, electro-depositing Al on the surfaces from an oxygen - and waterfree aprotic organoaluminium electrolyte. The surfaces may be provided by pre-treating the shaped article by: (a) pressure blasting the surfaces with particles of hard material e.g. corundum powder suspended in the liquid, e.g. paraffin or silicone oil or halogenated hydrocarbon e.g. a carbon perhalide, preferably followed by contacting with liquid then vapour perchloroethylene, and immersing in toluene; (b) liquid drop bombardment erosion of the surfaces, preferably of strip or sheet, with the liquid, e.g. benzene or toluene under N 2 , or a carbon perhalide; or (c) anodic detachment of a thin layer in an aprotic organometallic electrolyte, e.g. the Na-K mixed salt of a tetraalkyl Al complex, preferably by polarity reversal in the same cell as used for Al electrodeposition. Alternatively the surfaces may be produced by machining the articles under oil. The electrolyte may contain trimethyl and triethyl Al, and a solvent such as an aromatic hydrocarbon or ether, e.g. toluene, xylene, tetrahydrofuran, dipropyl or dibutyl ether or dioxane. The electro-deposition may be effected using an impulse current with polarity reversal cycles of frequency from 10 to 200c/s. The Al coating applied, e.g. 10 to 30 Ám thick, may be anodized in a DC H 2 SO 4  bath; and the oxide layer so formed may be dyed and/or printed, then sealed in hot water or super-heated steam. Alternatively the Al coating may be chromated, or, particularly for a Ti article, diffused into the surfaces by heating.

Title: Improvements relating to propellers
IPC: B64C27/54
Filed: 1950-06-09
Abstract: 676,570. Helicopters; variable-pitch propellers. RUSSO, G. June 9, 1950, No. 14520/50. Classes 4 and 114. An aircraft propeller or a helicopter rotor has a pair of blades mounted on a common shaft extending radially through a hollow boss, epicyclic gearing located within the boss and comprising a sunwheel co-axial with the rotational axis of the boss and meshing with a planet wheel on said common shaft whereby the angle of incidence of the blades is constant when the speeds of rotation of the sunwheel and the boss are the same and including means for continuously varying the angular displacement of the sunwheel relative to the boss in order continuously to vary the angles of incidence of the blades as the propeller or rotor rotates. The rotor blades 34, 34' are rotatably supported in a hollow hub 11 which is extended by a hollow shaft 10 enclosing a shaft 23 coupled to the rotor blades by gears 24, 24'. The shaft 10 is connected to an engine driven shaft 1 by gears 3, 3<SP>1</SP>, a shaft 4, gears 5 and 6, shafts 30 and 31 and gears 8, 9. The shaft 23 is driven by the shaft 1 at a speed normally the same as that of the shaft 10 by a differential mechanism of which the casing 19 is fast with a gear 7 and a pinion 18 is connected to gears 15, 16. The shaft 1 is cranked at 2 and connected by a link 12 to a member 13 mounted on a fixed pivot 14 and grooved to accommodate a slider 35 loosely mounted on a manually controlled lever 36. The lever 36 is provided with a fixed block 44 which engages a rigid guide 42 stepped at 43, the free end of the lever being pivoted at 41 to a lever 40 mounted on a fixed pivot 45 and connected at its other end to a member 38 which is coupled to the block 35 by a link 37 and to the gear 15 by a link 39. The pivots 41 and 14 and the step 43 are aligned so that when the lever 36 is positioned with the block 44 engaging the step 43 the rod 12 will reciprocate the member 13 without affecting the gear 15. Movement of the lever 36 to either side of the mid-position causes the member 13 to transmit a reciprocal rotation to the wheel 15 through the linkage 37, 38, 39 which by virtue of the differential gear will cause the hub 11 to act as an epicyclic gear and effect cyclical changes of pitch of the blades 34<SP>1</SP>, 34". The length of the step 43 and the links 40 and 38 are so arranged that axial movement of the lever 36 at the mid-position will reverse the pitch of the blades: To permit selection of the azimuth in which the lift vector is inclined the shafts 30 and 31 are spirally grooved and connected by a sleeve 29 which is moved axially by a lever 33 to ' superimpose a selected differential movement on the shafts 23 and 10.

Title: Improvements in facsimile transmitting and reproducing systems
IPC: H04N1/00
Filed: 1943-09-06
Abstract: 582,243. Facsimile transmission systems. DEHN, F. B. (Press Wireless, Inc.). Sept. 6, 1943, No. 14540. [Classes 40 (iii) and 40 (v)] In a facsimile transmitter a modulated subcarrier is produced by applying control potentials to the grid of a reactance-control tube 35 which is connected in series with the lowcapacity condenser 45 across the tuning circuit 42, 43 and in the control-grid cathode return of oscillator tube 33, having a frequency of 266Œ.5 kc. the output of which is mixed in tube 54 with the output from oscillator 34 (262 kc.). Signals for controlling tube 35 are derived from the transmitter 1 in the form of amplitude modulated carrier at a frequency of 1800 c.p.s. and fed through amplifier 6, frequency doubler 22 and rectifier 28 having a filter 29, 30, 31 in its output. The output from tube 54 modulates a radio frequency carrier in 70 and this is received at 71 (Fig. 2), the detected signals being fed therefrom to a limiter tube 73 operating with delayed A.V.C. derived from duo-diodetriode tube 74. The output of tube 73 is tuned to 3500 c.p.s. to provide a pass band from 2500-4500 c.p.s., so that no harmonic frequencies of the input modulation can be fed to amplifier 105. The latter feeds a rectifier 107 through a frequency doubler 106, the thoroughly smoothed output of the rectifier being fed to push-ball mixer tubes 126, 127 for combination with oscillations from tube 119. An amplitude-modulated output at 1800 c.p.s. appears at 129 and is fed via amplifier 131 to the facsimile machine 118.

Title: Jet propulsion engines
IPC: F23R3/18
Filed: 1956-05-10
Abstract: 822,037. Generating combustion products under pressure. NATIONAL RESEARCH COUNCIL. May 10, 1956 [July 21, 1955 ; Feb. 9, 1956], No. 14592/56. Class 51 (1). A jet propulsion engine comprises a main combustion stage and a reheat combustion stage, the latter comprising a flame stabilizing device and means for introducing fuel upstream thereof, means also being provided for projecting streams of fluid from the downstream edge of the flame stabilizing device into the path of the combustion gas stream flowing past the stabilizer so as to prevent the onset of screech combustion. The fluid may be fuel or water or a gas such as air or it may be a portion of the combustion gases themselves. In Fig. 2 the flame stabilizer 15 is of conical form and a tubular ring 17 having a series of outlets 19 is disposed within the downstream edge thereof, fluid supplied through the pipe 18 issuing through the outlets 19 in the form of a conical spray 20. If the fluid is water the outlets in the ring 17 are disposed so that the water is directed into the centre of the conical flame stabilizer, the resulting steam issuing past the downstream edge of the stabilizer being effective to reduce screech. The tubular ring may be disposed on the outer surface of the conical stabilizer at the downstream edge. In the case of an annular V-section flame stabilizer the fluid manifolds may be disposed either on the inner or outer surfaces thereof. When the fluid is combustion gas, a vane 31 may be associated with the stabilizer 30 so that the velocity of gases flowing through the convergent space therebetween is increased, the stream of increased velocity issuing at A into the main gas flow. A flame stabilizer comprising six V-section troughs is shown in Fig. 7, a vane 36 being associated with one surface of each trough 34. In the case of a flame stabilizer of annular V-section form a cylindrical ring may be associated with either the inner or the outer surface thereof to provide an annular passage of converging form. Where two annular flame stabilizers of V-section are provided they may be disposed so that the annular convergent space between the two stabilizers acts to produce a stream of combustion gases flowing past the downstream edges of the stabilizers. Similarly the convergent spaces between pairs of straight, parallel flame stabilizers may be so used.
