Filed: 1960-04-04
Abstract: 889,609. Lift door operating appliances. INVENTIO A.G. April 4, 1960 [April 6, 1959], No. 11752/60. Class 65(1). The lift cage doors 1, 2 each carry driving means which, during opening and closing movement, engage the corresponding shaft door and couple the doors together, the driving means comprising two levers 13 pivotally mounted on axles 11, 12 which, in plan, are inclined relative to the cill of the cage for movement between a position in which they lie on the cage side of the edge of the shaft cill and another position in which they extend to engage the shaft door. The levers are controlled by straps 15 connected to one end of an upwardly spring biased rod 17 which tends to move the levers towards the extended position. The upper ends of the rods 17 carry rollers 24 which abut a bar 25 vertically displaceable by means of a bell crank 26 and a connecting rod 29 pivoted to a lever 30 freely rotatable about the crank shaft 31 of the door actuating means. During movement of the doors the bar 25 is held in its upper position by the rods 17 but as the doors approach the closed position a stop 32 on the shaft 31 abuts the lever 30 and turns it to depress the bar 25 and rods 17, thus retracting [he arms 13 from engagement with the shaft door. The arms carry rollers 14 which embrace fixed and displaceable bars 22, 23 respectively on the shaft door, the movement of the latter when engaged by a roller serving to unlatch the door. The cage doors are provided with safety ledges 1a; 2a respectively of known type which are displaced if the doors encounter an obstruction. Specification 889,610 is referred to.

Title: Improvements in or relating to the production of 2-(4-morpholinyldithio) benzothiazole
IPC: C08K5/00
Filed: 1964-03-23
Abstract: 2 - (4 - Morpholinyldithio) benzothiazole is obtained by preparing and heating a mixture of morpholine, sulphur, an inert organic solvent and 2 - mercaptobenzothiazole or 2,21 - bis - (benzothiazyl) disulphide to a temperature above the crystallization point of said mixture, and adding at least a chemical equivalent of an aqueous solution of a water-soluble oxidizing agent to said mixture prior to the crystallization of any of the 2-(4-morpholinyldithio) benzothiazole product.  The oxidizing agent is preferably added over a period not exceeding 2 1/2 mins. and the reaction is completed in a maximum period of 10 minutes.  Suitable oxidizing agents are those water-soluble oxidizing agents which have sufficient solubility in water to produce solutions that have a concentration which is at least 1.2 molar, preferably 1.9 to 2.2 molar, such as sodium hypochlorite, hydrogen peroxide, ammonium persulphate, potassium, permanganate and calcium hypochlorite.  Suitable inert organic solvents are C3-C5 aliphatic alcohols and aromatic solvents such as benzene, toluene and xylene.  The proportion of solvent used may be approximately 110% by weight based on the weight of 2,21-bis-(benzothiazyl) disulphide or 2-mercaptobenzothiazole used. Morpholine and sulphur are preferably used in at least a slight molar excess, e.g. approximately 110% of the chemical equivalent based on the mols. of 2,21-bis-(benzothiazyl) disulphide or 2-mercaptobenzothiazole.  The reaction temperature is preferably at least 5 DEG  C. above the crystallization temperature of the initial solution of reactants and for most solvent systems this is at least 55 DEG  C.  The upper temperature limit should not exceed the boiling point of the inert solvent.  The process may be carried out continuously.

Title: Semi-conductor translating devices and method of making the same
IPC: H01L21/18
Filed: 1957-04-15
Abstract: 863,119. Semi-conductor devices. HUGHES AIRCRAFT CO. April 5, 1957 [June 1, 1956], No. 12285/57. Class 37. A method of making a semi-conductor device comprises the steps of producing a regrown region of one conductivity type on one surface of a wafer of the opposite conductivity type, ohmically affixing to the regrown region a mechanical backing of the same material and same conductivity type as that region and subsequently reducing the thickness of the wafer to less than that of the backing. In one embodiment a PN junction diode is produced by the following steps. Molten aluminium is evaporated on to one face of a wafer of N-type silicon and cooled to form a regrown crystalline P-type region thereon. A backing wafer of heavily doped P- type silicon on one face of which an aluminium layer has been evaporated is then placed with its coated face abutting the regrown P-type region and the assembly heated to form a single body (Fig. 5). The opposite face of the N-type wafer is then lapped or etched to reduce its thickness to less than that of the backing and a gold antimony alloy 23 is evaporated on and alloyed to it (Fig. 6). A gold gallium alloy 22 is also evaporated on and alloyed to the surface 17 of the backing wafer. The assembly may then be diced and each of the PN junction diodes thus formed provided with electrode wires. In order to form a PNP transistor aluminium is evaporated on and alloyed to the entire opposite face of the N-type silicon wafer after the lapping or etching operation in the above-described process to form a second regrown P-type region. Alternatively a series of small area PN junctions may be formed on this surface by fusing acceptor wires to it or by evaporating the aluminium through a multi-apertured mask. Use of a backing of the same basic material as the wafer facilitates cutting and etching operations and reduces mechanical stresses due to thermal expansion. Germanium is mentioned as an alternative material to silicon. Specification 807,728 is referred to.

Abstract: 741,123. Washing granular materials. LOGUE, L. H., and BAILEY, R. S. May 25, 1951 [May 25, 1950], No. 12297/51. Class 82 (2) A horizontal rotary drum separator for sink and float separation is divided into coaxial intercommunicating inlet and outlet compartments, the intercommunication being at a level above the outlet means for each of the compartments so that there is no interchange of liquid between the compartments, means being provided in the inlet compartment for lifting sunken heavy material and transferring it to the outlet compartment and means being provided in the outlet compartment for discharging heavy material. A drum 10 comprises compartments 26, 27 each provided with lifters 42, shaped and slotted as in Fig. 5. Solids to be separated are fed into the compartment 26 through the shoot 50 to which separating medium is fed at 65. Floats leave at 62 and sinks are received by the lifters into a transfer trough 69 from which they pass at 74 into the compartment 27. Separating medium of greater density is fed at 83 into the trough 69 and thence into the compartment 27 from which middlings pass at 38a into the shoot 89, sinks being lifted into the outlet trough 69a which is flushed with separating medium. A flexible guard 92 in each compartment prevents floats becoming caught up by the lifters 42. The side 72 of the shoot 69 is formed as a grid and is flexible. In Fig. 6, high ash content coal is fed at 135 into the separator 137, the floats from the first compartment 138 passing to a screen 141 and discharge; middlings floated in the second compartment 139 pass to screens 147, 148, the coarser middlings between are crushed at 151 and returned to the circuit. Sinks pass to the screen 144 and discharge. A similar circuit, without feed back of middlings, for treating iron ore is also described.

Abstract: 1351590 Data processing INTERNATIONAL BUSINESS MACHINES CORP 15 March 1973 [31 March 1972] 12470/73 Heading G4C In a digital data processing system in which a plurality of central processor units CPU1- CPUN (Fig. 1) have areas of main storage 200 assigned to them, (1) to access its assigned storage a CPU inserts a zero address in the higher order bits of its address register, this being modified by a prefix representing the base address of the assigned storage, the prefix being held in its control register, (2) to access the storage of CPU1, the prefix is entered into the address register, this being modified so that the higher order address bits applied to the main store are zero and (3) to access the storage when any other central processing unit the address bits in the address register are not changed. As described the modification of the address is effected by the logic circuitry of Fig. 3 in which when the higher order address bits on lines A8- A19 are all zero (i.e. when the processor is addressing its own storage) AND gates 12A- 12D are enabled by a negative signal on lead 11 and AND gates 8A-8D are enabled by a positive signal on lead 7 so that the prefix address bits P8-P19 are applied to the main store (since gates 8A-8D contribute only zeerso). When the bits on lines A8-A19 correspond to the prefix, gates 12 are disabled by a positive signal on lead 11 (since at least one of OR gates 10A-10B is enabled) and gates 8A-8D are disabled by a negative signal on lead 7 (since the outputs of exclusive OR gates 4A-4D are "zero") so that output lines 16A-16D are forced to their zero state. When a value other than zero or the prefix is applied to lines A8- A19 at least one OR gate 10A-10B is enabled to disable the AND gates 12A-12D and at least one of the exclusive OR gates 4A-4D is enabled to enable associated OR gates 6A-6B to provide an enabling input to AND gates 8A-8D so that the address bits on lines A8- A19 are applied unchanged.
