Title: Improvements in devices for launching rockets from aircraft
IPC: F41A9/03
Filed: 1946-11-07
Abstract: 631,247. Launching rockets from aircraft. ROBERT, R. A. Nov. 7, 1946, No. 33134. Convention date, Nov. 14, 1945. [Classes 9 (i) and 9 (ii)] A rocket-launching apparatus has the rockets stacked in vertical rows, successive rockets of each row being connected by an articulated system folded when the rockets are stacked so that adjacent rockets touch, the system opening out as the leading rocket of each row moves into the launching position. Inside a magazine or container for rockets, conveyer screws 11, 12, 13, 14 (13 not shown), are arranged with the rockets 23 supported in the convolutions of the screws, so that upon rotation of the screw shafts 15 the rockets are fed towards the magazine outlet. The rockets in each row are connected by a system of links so that upon ejection of the leading rocket in each row into the launching position these rockets are supported by the next following rockets. The shafts of the screws rotate in bearings 16 and are driven through pinions 17, 18. The rockets In the central row are supported on each side by the screws and the rockets in the lateral rows are supported on one side by the screws and on the other side by guide posts 19, 20. An element 21 fitted over the screws moves down with the rockets and maintains them in position by means of plates 22. Each rocket 23, comprising a body 24, a cylinder 25 containing the propelling charge and a tail-piece 26, is provided with two supporting clips 27, 28 on which are linked the suspension links 29, 30. The forward link 29 has a hook extension 31 engaging with a clip 32 of the rocket below. The rear link 30 has a two-armed hook 33 engaging with a clip 34 on the rocket below, a wire across the arms of the hook securing the hook in position. When each link has descended to the vertical position, to prevent a return motion of the link a bent 36 on its head engages with a spring-pressed stud 38 on the supporting clip above. Each rocket is guided during its descent by the pressure of its base against the wall of the container. Upon ejection the rocket moves backwards being no longer constrained by the container and the links supporting it rotate into the vertical position. The base of the rocket by coming into contact with an abutment 39 stops the drive to the screws. When the rocket is launched the propulsive force breaks the retaining wire in the suspension link. The freed links are retracted against the rocket body by springs and the withdrawal of the pressure from the abutment 39 restarts the drive to the screws. The guiding element 21 also supports the uppermost rockets when they reach the launching position. The container is refilled by presenting linked rockets at the outlet and rotating the screws in the reverse direction. The vanes of the tail-piece 26 open out under the action of springs after the rocket leaves the container.

Abstract: 1,002,315. Dispensing from collapsible tubes. D. CHIPPERFIELD. Aug. 2, 1963 [Aug. 29 1962], No. 33186/62. Heading B8D. The contents of a collapsible tube are expelled by means of rollers 14, 33 under ratchet control which advance up the tube a limited distance each time a pivoted platform 21 is depressed. The platform 21 is integral with a cover-plate having side members 27 in which the spindle ends 32 of the roller 33 are journalled, and is urged upwards by a spring 12. Further springs 17 urge the rollers 14, 33 together. As the platform 21 is pressed down, a spur-wheel 34 of the roller 33 is caused to move with a planet action about a spur wheel 16 of the roller 14 which is held by a spring-urged pawl 9. This movement is limited by slots 18 in members integral with a base-plate 2. On release of the platform 21, the spur-wheel 16 of the roller 14 is rotated past the pawl 9 the distance of one tooth on the spur wheel. The rollers may be corrugated or serrated; and the platform 21 replaced by a knob or lever.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J21/36
Filed: 1959-09-30
Abstract: 864,303. Thermionic valves. SIEMENS & HALSKE A.G. Sept. 30, 1959 [Sept. 30, 1958], No. 33214/59. Class 39(1). In a discharge tube including a grid assembly sealed into the tube envelope, the grid extends in a plane across an aperture in a supporting frame to which it is attached and a metal ring is bonded to the grid in such a way that its unbonded surface is parallel to the plane of the grid. As shown, a grid comprising a plane mesh of crossed wires is gold or copper soldered to a supporting frame and a malleable metal ring 5, e.g. of copper, gold or silver, is pressure bonded in a jig on to the soldered grid mesh to form a cold weld, the malleable metal filling all the cavities which were created by soldering the grid mesh to the frame 4. The jig has a non-deformable distance piece which maintains the desired dimension between the unbonded surfaces of the frame 4 and ring 5 and ensures that these surfaces are parallel to each other and to the grid mesh so that the grid-cathode distance can be accurately determined. The grid assembly together with a metal foil 3 and the ceramic wall portions are then pressed together and heated, thus producing a diffusion weld between ring 5 and foil 3, whilst annular metallic members 6 and 7, previously secured to the ceramic wall portions, are soldered together.

Title: A process for the production of tetraalkyllead compounds
IPC: C07F7/24
Filed: 1965-08-03
Abstract: Tetraalkyl lead compounds are prepared by reacting an alkali metal lead alloy and an alkyl halide, and contacting the reaction mass, in the absence of an aq. liq. phase, with a gas or vapour inert to the reaction products at a temp. of 25-200 DEG  C. to vaporize the tetraalkyl lead which is recovered.  The inert gas or vapour may be: N2, air, super-heated steam, a rare gas e.g. He, alkyl halides e.g. of 1-5 C atoms and preferably the same as used in the synthesis, or hydrocarbons having e.g. 1-10 C atoms. The velocity of the gas at contact may be from 0.05 ft/sec. to sonic velocity and the pressure may be 20 ins. vac up to 300 p.s.i.g.  The reaction may be carried out in the presence of a minor proportion of an inert diluent, e.g. an inert hydrocarbon which may be vaporized with the inert gas and it may be present as 5-25 parts by wt. per 100 parts of Pb in the alloy. The gas and reaction mass may be contracted by fluidizing a bed of the mass with the gas, said bed optionally having an overflow arrangement for the stripped solid, or by feeding the gas through a bed of the mass at a velocity insufficient to support the bed, which may be static or agitated by a stirrer or vibrator. The inert gas may be recycled after removal of the tetraalkyl lead therefrom

Title: Improvements in and relating to a Furnace Heating Control
IPC: C23C2/40
Filed: 1967-07-21
Abstract: 1,187,639. Automatic temperature control of furnaces; fluid-pressure servomotor systems. ELECTRIC FURNACE CO. July 21, 1967 [July 25, 1966], No.33692/67. Headings G3P and G3R. A furnace comprising a succession of heating zones through which is passed metal strip to be heated to a desired exit temperature is provided with a master controller generating a signal in response to the difference between the actual and desired strip exit temperatures, a succession of zone controllers each generating a signal in response to the difference between the zone temperature and a pre-set maximum zone temperature, and a control system for the zone heaters responsive to a comparison between the master signal and the zone signals to bring the heaters successively into and out of operation and to regulate the heat output of those in operation. The described furnace, Fig.2 2 (not shown) has two zones using gas-fired burners supplied with air and fuel which are separately regulated to maintain a predetermined air/gas ratio, the gas flow being automatically adjusted in response to adjustments of air flow produced by operation of the control system. The burner arrangement together with a known jet pipe relay control for adjusting the air and gas valves is described, Fig.4 (not shown). The heater control system shown in Fig.5 includes pyrometer controllers STC, Z1LC, Z2LC respectively supplied by the strip thermocouple ST (or by a strip radiant heat sensor) and by the zone thermocouples CT1, CT2. The controller STC provides an air pressure signal of predetermined range which is supplied to computer controllers 55a, 55b also supplied with pre-set bias signals from manually adjustable members 58a, 58b, these latter signals determining the order in which the zones are brought into operation. When a computer controller, e.g. 55a receives a master signal exceeding the zone bias signal, the controller 55a supplies a signal to a comparator 52a also supplied with a signal from the zone controller Z1LC. Comparator 52a chooses the lower of these two signals and passes it to members 57a, 67a which control a pneumatic valve motor 60a for adjusting the setting of a valve AV1 controlling the air supply to the burners. Until the zone reaches its pre-set maximum temperature, the signal from the comparator 52a will be representative of the master signal and the burners are controlled in accordance therewith. When the pre-set maximum temperature is reached the zone controller Z1LC takes over and maintains this temperature until the master signal changes to require a reduction in heating. In a modification, Fig. 6 (not shown) a four zone furnace is provided with an all-electrical control system comprising pyrometer controllers and relays and operating in a generally similar manner to that described, the master controller acting through the zone controller to vary the zone heat output. The gas burners may be replaced by electrical heaters of the resistance or radiant tube type,
