Title: Process for the catalytic hydrogenation of hydrocarbons
Inventor: ABEN PIETER CORNELIS
IPC: C10G45/50
Filed: 1967-07-12
Abstract: 1,130,848. Hydrofining; hydrogenating hydrocarbons. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 12 July, 1967 [14 July, 1966], No. 32149/67. Heading C5E. Hydrogenation of hydrocarbons or mixtures of hydrocarbons comprising aromatic and/or other hydrogenatable compounds is effected at elevated temperature and under hydrogen pressure with a catalyst composed of a carrier consisting entirely or substantially of SiO 2  and a combination of at least one sulphide of W, Mo and Re, and at least one sulphide of Ni, which catalyst has been treated during and/or after the conversion of the metal components into sulphides with HCl or with a precursor therefor. Reference is made to hydrofinishing of lubricating oil fractions and waxes to improve colour, colour stability or to remove small quantities of impurity. Crude benzene and fractions having a boiling-point in the gasoline, kerosine, gas-oil or lubricating oil range may be hydrodesulphurized in a manner as set forth above. Typical reaction conditions are a pressure of 25-150 atmospheres absolute, a temperature of 150-425‹ C., and a space velocity of 0À4-10. Examples describe the hydrogenation of benzene to cyclohexane.

Title: Improvements in the formation of junctions in semiconductor bodies
IPC: C30B31/02
Filed: 1956-10-22
Abstract: 844,692. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 22, 1956 [Oct. 24, 1955], No. 32157/56. Class 37. A method of making a semi-conductor device comprises the following steps; coating a surface of a semi-conductor, body with a layer of material which reacts chemically or physically with an activator impurity; heating the coated body in a vapour containing the impurity to react the impurity and layer material and to diffuse the impurity into the body to a depth which is greater beneath the layer; and then removing material from the body to a depth exceeding the depth of penetration of impurity on areas not covered by the layer but less than the penetration depth under the layer. In the embodiment indium layers 2, 3 are deposited, e.g. by vacuum evaporation through a mask, on to opposite faces of a P type germanium wafer containing indium or gallium, and the wafer then heated for 10 hours at 800‹ C. in a reducing atmosphere containing 10<SP>16</SP>-10<SP>18</SP> atoms/cc. of arsenic. As a result of this treatment an N type arsenic doped layer of the form shown in Fig. 1 is produced. A surface layer of uniform thickness is then removed from the wafer by abrading or chemical or electolytic etching to expose the P type material as shown in Fig. 2 leaving islands 6, 5 of N type material which serve as emitter and collector zones in the finished transistor. Base emitter, and collector connections 8, 7, 9 are then soldered to the body as shown. A PNP transistor is made by a similar method but using an element from Group V for the layer, and a vapour comprising an element from Group III. The greater depth of diffusion beneath the layer is thought to be due to the fact that the concentration of impurity atoms is greater in the layer than in the surrounding atmosphere and to the intimate contact between the layer and semi-conductor. The impurity vapour pressure must be well below the equilibrium vapour pressure to prevent formation of a molten surface alloy in the uncoated regions which would increase the penetration in these regions. To permit accurate control of the junction areas the layer or the product of its reaction with the vapour should remains solid during the diffusion process.

Title: Improvements in and relating to a mechanism for automatically moving filter plates
IPC: B01D25/164
Filed: 1964-08-07
Abstract: 1,079,407. Unstacking press filters. SEITZWERKE G.m.b.H. Aug. 7, 1964 [Aug. 9, 1963], No. 32200/64. Heading BID. Plates 7 of a filter press are unstacked by means of brackets 18 as the plates being engaged by conveyor screw sleeves 11 which are carried by and rotate with shafts 10 running the length of the press and which are also axially displaceable along the shaft so that plates may be unstacked one by one. The conveyor member is longer than the length of travel of a plate so that after movement of a plate that plate remains in engagement with the conveyor and the resulting reaction (since the plate has to remain stationary, Fig. 4) causes axial displacement of the conveyor so that it moves out of engagement with the plate and into engagement with the next following plate. A spring 21 urges the conveyor upon commencement of the unstacking against the bracket 18 of the first plate. The axial movement of the conveyor is braked by either brake linings on the shaft and/or on the bore of the conveyor, or by manufacturing the shaft of suitable brake material, or by fitting a spring 19 on the conveyor to engage in notches 20 in the shaft. A resilient disc 23 on the conveyor prevents two plates from moving at once. The plates have beaded edges 5, sludge channels 6 and are lined with filter cloth. The brackets 18 as well as engaging the conveyors hook onto the supports 4.

Abstract: 850,061. Electric indicating systems. BECKMAN INSTRUMENTS Inc. Oct. 13, 1958, No. 32599/58. Class 40 (1). Apparatus for indicating the values of a group of voltages derived e.g. from thermocouples, strain gauges, etc., comprises means for adjusting the amplification of the system by a predetermined factor corresponding to each individual voltage source as the input voltages are cyclically sensed. As shown (Fig. 1) the predetermined amplification factors are set up in a programme storage unit 21, together with other predetermined features of the individual voltages, to be indicated. The input voltages are connected to the terminals 17 of a switch 10, to be fed cyclically to a variable gain amplifier 11, A.C. input voltages as from transducer 18 being first fed through an A.C. to D.C. converter 26, introduced by a switch 30 controlled by the information set up in storage unit 21. Thus cyclic switch 10 selects a particular input signal, selects the associated bank of predetermined data in storage unit 21, and selectively energises a channel number generator 25a to provide a digital output indicative of the particular voltage source being sampled, to be recorded with the voltage measurement, the gain of amplifier 11 is adjusted by control of an attenuator 31 in a negative feedback path and the amplifier voltage is added to an offset voltage at 48 before being supplied to an analogue to digital converter 14 for feeding to a typewriter 80, or a card puncher 81, or a further computer 82, or an alarm typewriter 83, the latter being operated when the input to converter 14 is greater (or smaller) than an alarm level also set up in storage unit 21, or in a separate alarm memory unit 24. The cyclic operation of the switch 10 and the separate programme units is controlled by a timing unit 92.

Title: Improvements in back spacing mechanism for typewriting machines
IPC: B41J19/62
Filed: 1919-12-30
Abstract: 160,924. James, R. W., (Remington Typewriter Co.). Dec. 30,1919. Back-spacing mechanism.-Backspacing mechanism mounted for movement with the carriage in caseshift comprises a single member 70 embodying a pawl 75 and a projection 74 for holding the feed-rack 19 against releasing movement. The back-spacing key-lever is connected through lever and link mechanism to a bell-crank lever 64 moving in an horizontal plane about a shouldered pivot screw 65, one arm 66 of the bell-crank lever being pivotally connected with a two-part link 67, one part of which is pivoted at 68 to the back-spacing member 70. The member 70 carries a headed pin 71 engaging in a slot 72 in a supporting-bracket 73. When the backspacing key is depressed, the member 70 first pivots about the pin 71, the integral pawl 75 engaging with teeth on the upper side of the feedrack, and the integral projection 74 engaging the underside of the rack. At the finish of its pivotal movement, the member 70 slides to the end of the slot 72, pulling the carriage and rack with it, and in this position acts as a cramp across the rack, retaining the pawl in engagement therewith and preventing release of the carriage. As a further safeguard in case insufficient pressure is applied to the back-spacing key, positive means is provided to lock the pawl and prevent release, such means consisting of a contact 76 on the support 73 which retains the holding projection 74 in engagement with the underside of the rack. Upon release, under the action of a returning spring 79, the pivotal movement of the member 70 is limited by the stop 78, the projection 74 riding down the incline 77. The member 73 is connected with the rack by a sheet metal bracket 83 secured by screws 84, 85 to allow movement of the back-spacing mechanism with the carriage and rack in case-shift.

Reactor 1 has a screw or pump to feed solids to inlet 3, or solids may enter entrained in the reactor fluidizing gas.  In particular examples reactor 1 is preheated and filled, to level 4, with powdered coal or coke and ilmenite (titaniferous ore) or TiO2 (rutile), through inlet 3.  Chlorine enters at 61, expanding the bed to level 5, and TiCl4 and FeCl3 or TiCl4 only is recovered from the gas leaving at 6. The reaction temperature 850-950 DEG  C. is maintained by solids exchange with water-sprayed vessel 8, which is fluidized with CO2, CO or N, and fresh solids are added at 3 or 11. Instead of coke mixed with the ore, CO mixed with the Cl2 may serve as reducing agent.  Other processes exemplified are reducing niobium chloride or niobium metal, using hydrogen in reactor 1 and in vessel 8 to form in addition some niobium hydride to facilitate removal at 9 by making the niobium particles friable; SiH4 decmposition to Si, using hydrogen in vessel 8; converting CuO to CuSO4; roasting arseno-pyrites and sulphides of Zn, Cu and Fe; reducing hematite to magnetite; and catalytic conversion of hydrocarbons, the solids in this case being catalyst particles, the fluidizing gas air.
