Abstract: 1283793 Epitaxial growth from the liquid RCA CORPORATION 6 Feb 1970 [14 Feb 1969] 5784/70 Heading BIS Successive epitaxial layers of crystalline semiconductive material are grown on a substrate by bringing the surface of the substrate into contact with a first solution of a semiconductive material in a molten metal solvent and cooling the solution sufficiently to deposit a first epitaxial layer of the semiconductive material on the substrate and then, whilst the substrate is still covered with a film of the first solution, a second such solution is brought into contact with the surface and further cooling undergone to deposit a second layer. These layers may be of the same or of dissimilar conductivity types and neither the solvents nor the semiconductive materials need be the same in each solution. Three or more layers may be deposited by continuing the process. Solvents which may be used are gallium, lead and tin, the semiconductive material being, e.g. gallium arsenide, silicon or germanium, these modified by the presence of donors, and substrates of such as gallium arsenide or silicon may be used.

Title: Manufacture of tetrachlorethylene and carbon tetrachloride
IPC: C07C21/12
Filed: 1957-02-20
Abstract: The invention comprises a process for the simultaneous manufacture of tetrachlorethylene and carbon tetrachloride in the gaseous phase, by the chlorination of a mixture of propane and propylene with a gaseous mixture of chlorine and hexachlorethane, in which the two gases are present in a molecular ratio between 1 : 0.03 and 1 : 0.1 and the quantity of chlorine with respect to the propane/propylene mixture is substantially stoichiometric, mixing the reaction mixture before reaction with tetrachloroethylene, carbon tetrachloride or mixtures thereof, in such quantities as to prevent the mixture becoming explosive, and carrying out the reaction on a fluidized bed of granular material at 485-520 DEG  C.  The free chlorine is then combined with tetrachloroethylene to reform hexachlorethane, the gases passing out of the reaction zone are cooled, and from the cooled gases there is separated on the one hand hydrochloric acid together with the tetrachlorethylene, the carbon tetrachloride formed, and the by-products which cannot be recycled, and on the other hand the hexachlorethane and diluent together with any intermediate compounds which can be recycled, fresh quantities of chlorine and the propane/propylene mixture equal to the quantities of chlorine and propane consumed being added thereto.  The fluidized bed may be composed of, e.g. sand, fuller's earth, pumice, kieselguhr, active carbon, di-atomaceous earth, and finely-divided metals, with or without catalysts such as chlorides of copper, barium, cobalt, nickel and cerium.  The apparatus used in the process of the invention preferably comprises a long cylindrical vessel of which only one part contains the solid material.

Patent GB-391290-A (GB)
Title: Improvements relating to electrical switch gear
IPC: H02H7/00
Filed: 1932-02-27
Abstract: 391,290. Protective cut-out arrangements. ELECTRICAL APPARATUS CO., Ltd. and WALTON, J. R., Vauxhall Works, South Lambeth Road, London. Feb. 27, 1932, No. 5935. [Class 38 (v).] In a system in which a motor M or other consuming apparatus is connected through a trailing cable T to a fixed point, as in colliery underground machinery, the supply is cut off in the event of the cable being disconnected or a conductor being connected to earth or in other circumstances. The cable includes power conductors, a pilot conductor P, and earth connection E, and is connected through an isolator or reversing-switch S to the motor. At the fixed point, shown as a gate-end, the lines are connected through a switch B, earthleakage transformer C, thermal overload devices D, and main contactor F, to the cable. A lowvoltage transformer G is arranged to energize a Wheatstone bridge R<1> .. R<4>, R<4> being connected at one end to E and at the other to P (when S is closed) and a manual switch K being. included in this arm of the bridge. With switches B, K closed and S open, the bridge is unbalanced and the relay H<1> is energized to open contract 6 and close 5, making at the latter a circuit from the secondary of transformer G to the relay H<2>. The latter closes and (1) makes a holding circuit for itself from secondary of G over closed contacts 7, contacts of earth-leakage thermal relay LT, closed contacts of a relay H3, closed contacts of relays D, winding of H<2>, and (2) preparing at 8 the circuit of closing- coil F1 of main contactor F. The switch S is then manually closed, thereby balancing the bridge and de-enerizing H<1>, but relay H<2> still remains closed over its locking circuit; closure of contacts 6 completes the circuit of Fl, which closes F and energizes the motor. If. now K or S is opened, the bridge is unbalanced and H<1> opens 6 to de-energize F<1>, but reclosure of the opened switch restores the original conditions. If either P or E breaks, or a shortcircuit occurs between them, the bridge is likewise unbalanced and H<1> likewise de-energizes Fl and disconnects the motor. The relay H2 only opens its contacts by opening of B, operation of D, LT, or H<3>, or if the supply voltage fails, and cannot be made to reclose them without opening K or S to unbalance the bridge. To avoid the objectionable opening and closing of F when an intermittent shortcircuit between P, E occurs, the relay H<3> is caused by short-circuit, current to open its contacts to de-energize H<2>, and its design is such that once it has opened them it does not allow them to reclose until it has been completely de-energized by opening K or S. Where a number of units are to be connected in succession, the link between 3, 4 is removed and those terminals are connected to terminals 1, 2 of the preceding unit, whereby the latter must be connected before the next unit in the series can operate.

Abstract: 766,087. Aerials. SADIR-CARPENTIER. Feb. 28, 1955 [March 1, 1954], No. 5963/55. Class 40(7) A wide band aerial comprises a slotted sheet of metal, the slot including at least one part which is of approximately circular shape and having a feeder connected to suitably selected points along its periphery. In one embodiment the aerial is formed by a relatively large conductive sheet having two circular openings 5 and 6 interconnected by a short channel 7 joining their nearest points. The periphery of each circular opening is made substantially equal to the mean operating wavelength and the feeder connected to the points 8 and 9. In another embodiment an almost closed circular opening 10 is made close to the edge 11 of a conductive sheet and connected by means of a short narrow gap 12 with the nearest point on the edge. The feeder is connected to the points 13 and 14 on the two sides of the gap. Slotted aerials of the types described may be incorporated into the structure of aircraft. For example the aerial of Fig. 3 may be associated with the leading edge of an aircraft fin (Fig. 4, not shown). In the case of a jet aircraft two such aerials may be located at the two sides of the air intake and symmetrical with reference to the medial longitudinal plane of the craft.

Filed: 1963-02-14
Abstract: 1,030,244. Buckles. R. F. GOINARD. Feb. 14, 1963 [Feb. 14, 1962; July 30, 1962], No. 6080/63. Heading E2A. An automatically releasable buckle for joining two ends of a safety belt includes a housing 6 securable at one end thereof to one end of the belt, guiding means 7 provided at the opposite end of the housing and defining a bore leading into the housing, rod means 8 securable to the other end of the belt and adapted to slide within said guiding means, a securing member 13 within said housing mounted for sliding movement in the same direction as the rod means and for pivotal movement about an axis transversely of said direction and adapted to engage said rod means, spring means 23 between said housing and the securing member for urging said securing member into a position in which said rod means is firmly engaged thereby and resiliently actuated cam means 29 positioned within the housing and co-operating with the securing member so as pivotally to disengage said securing member from the rod means when said securing member is returned towards a normal position by the spring means after the rod means and securing member have been displaced relatively to the housing by a strong force exerted on the belt. In the construction shown the rod means 8 is part of an element 2 which includes an elongated ring 4 to which one end of the safety belt is attached and the housing is part of an element 1 which also includes an elongated ring 3 for the other end of the belt. The rod means 8 is grooved and a pin 9 in the guiding means prevents its rotation relative to the housing. The rod means 8 carries a pin 19 which is engageable by a hook 17 of the securing member 13 which is mounted for the sliding and pivotal movement, on a pin 14 which engages a slot 15 in the member 13. When there is no force exerted on the belt and the member 13 is engaged with the pin 19 its end portion, on the opposite side of the pin 14 to the hook 17, is in a groove 35 of the cam means 29. The cam means 29 is slidable in a part 27 transversely of the housing 6 and it is biased by a spring 32. When force is exerted on the belt the rod means 8 is partially withdrawn from the housing 6 until the movement is limited by the pin 14 coming into contact with the end of the slot 15. This movement of the member 13 moves its end portion out of the groove in the cam means 29 and the cam means then moves transversely of the housing under the pressure of its biasing spring 32. When the force is removed from the belt the spring 23 moves the member 13 towards the cam means and its end 21 which is bevelled comes into contact with a surface of the cam means 29 and this pivots the member 13 so that the hook 17 becomes disengaged from the pin 19 to free the rod means 8 which can then be withdrawn from the housing. The cam means 29 can be restored to the position in which the member 13 engages its screw 35 by manual pressure through an aperture 30 in the housing.
