Title: A process for the production of silicon tetrahalides
IPC: C01B33/08
Filed: 1969-03-04
Abstract: 1,254,785. Silicon tetrahalides. DEUTSCHE GOLD-UND SILBER SCHEIDEANSTALT. 4 March, 1969 [28 March, 1968], No. 11451/69. Heading C1A..  Silicon tetrahalides are prepared by reacting one or-more halosilanes of the formula H n SiX 4-n,  in which X is a halogen and n is an integer from 1 to 3, with a hydrogen halide at a temperature of from 200‹ to 800‹ C. in the presence of an inert solid material having a large surface area such as active carbon, finely divided aluminium oxide or silicon dioxide. In Examples 1 and 2, a mixture of SiCl 4 , HSiCl 3 , H 2 SiCl 2  and H 2  prepared by reacting silicon with hydrogen chloride is converted to a mixture containing almost no H 2 SiCl 2  by passage through a bed of active carbon: in Example 3 the initial mixture contained no H 2  or H 2 SiCl 2 : in Example 4 a mixture of H 2 SiCl 2  and HSiCl 3  was converted to a product containing mainly HSiCl 3  with 10% SiCl 4 : in Example 5 a mixture of HSiCl 3  and HBr was converted to SiCl 3 Br.

Title: An arrangement for the distant control of switching devices
IPC: H02J13/00
Filed: 1927-04-29
Abstract: 270,325. Akt.-Ges. Brown, Boveri, et Cie, (Assignees of Oesterreichische Brown, Boverie-Werke, Akt.-Ges.). April 29, 1926, [Convention date]. Systems depending on two or more machines; switching-systems.-The operation of switches or a series of switching operations in distant substations, etc., is effected through a line or lines normally conveying indications of network conditions, such as voltage at a given point. The operated switches may initiate the operation of apparatus anywhere in the vicinity of such line or lines and not necessarily connected with the network. The existing indicating instrument is used to indicate in addition the progress of the controlled operations, such indication being limited to the duration of each operation. As shown in Fig. 1 the network A is connected by lines B (one of which may be an earth return) with a distant voltmeter V. One of these lines is taken through a relay coil Land through switches N1 - - Nn normally short-circuiting resistances O1 - - On in the control apparatus U. The voltmeter V has a short-circuiting pushbutton P which is held closed by a coil Z after operation to initiate the distant switching by the current resulting from short circuiting the voltmeter. This current closes a switch M in the distant control apparatus which connects a motor H to a source such as the subsidiary transformer F energized from the feeder C. The motor H drives a controller drum J which, for example, causes the operation of mechanism closing the main switch D and initiating the starting of subtraction machinery. A cam K holds the switch M closed whilst the control drum is moving between positions so that the coil L need not remain energized and a cam K, first opens the short-circuit to release the push-button P and allow the voltmeter to show its normal reading and then switches a resistance 01 in series to cause the meter to give reduced readings, thus indicating the progress of the switching operation. The termination of the operation is indicated by the return of the voltmeter to normal readings, caused by the cam K reclosing the switch N1 when the first controller position has been reached. At this point the cam K allows the switch M to open. The push button P is released on the first operation of the switch N1. By using graded resistances 01 - - On the voltmeter may be caused to register on different portions of the scale for successive switching operations each of which may take place in turn on successive operations of the button P. The resistances may be electrically controlled from the controller drum. The Specification as open to inspection under Sect. 91 (3) (a) states that selective arrangements of known kind may be used in conjunction with the controlling apparatus. This statement does not appear in the Specification as accepted.

Title: Improvements in or relating to methods of manufacturing magnetic matrix arrangements
IPC: G11C5/12
Filed: 1966-03-16
Abstract: 1,146,615. Magnetic storage apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 March, 1966 [19 March, 1965], No. 11525/66. Heading H3B. A magnetic storage matrix is made from a semi-conductor wafer, the peripheral areas of the wafer having transistors and diodes formed on insulated islands and the magnetic storage elements being formed by magnetically coating a network of grooves surrounded by the islands. A silicon wafer has an appropriately doped layer for the initial stages of the manufacture of diodes and transistors grown epitaxially thereon. This layer is then removed as far as the areas to be occupied by the diodes and transistors and coated with a silicon insulating layer, Figs. 1, 2 (not shown). The insulating layer has grown on to it a polycrystalline layer and the opposite side of the block is removed by grinding so that a semi-conductor wafer is obtained which has insulated islands (I) for the formation of the transistors and diodes, the finished wafer being in the form indicated in Fig. 3 (not shown) and comprising a central square area surrounded by the insulated islands. After the formation of the transistors and diodes grooves N, Fig. 4, are etched in the semiconductor material P and the surface of the wafer oxidized. At the cross-over points of the grooves a rectangular hysteresis loop magnetic layer is deposited from the vapour phase so that the grooves are coated entirely as far as their edges and a little way beyond, Figs. 5 (not shown) and 6. The grooves are then coated with an insulating layer Sch<SP>1</SP>l and the X direction conductors L 1  laid down by a photo-etch process, which conductors and/or resistors are insulated by layer Sch 2  before conductors L 2  extending in the Y direction are formed. After the desired number of conductor patterns have been obtained a further magnetic layer M 2  is applied. Either or both magnetic layers may act as the storage element. In the arrangement of Fig. 7 (not shown) the storage elements are located in grooves between the cross-over points. In order to connect the conductor patterns with the electronic apparatus the grooves N are enlarged at their ends adjacent to the insulated islands I, Fig. 8 (not shown).

Title: Chair corner bracket boring machine attachment
IPC: B23Q3/06
Filed: 1936-04-25
Abstract: 469,206. Drilling-machines. KEARLEY, F. J. April 25, 1936, No. 11858. [Class 83 (iii)] In a horizontal or spindleturret drilling - machine detachable mechanism is provided for automatically positioning the work before a number of drills in succession so that a number of successive drilling operations may be performed. The attachment is particularly designed for drilling corner brackets or blocks such as are used in the manufacture of chairs &c. The brackets a are stacked in a vertical shoot 25, Figs. 2 and 3, and the lowermost bracket is normally held by a spring plunger 18 carried by a vertically adjustable arm 17. A hand lever 4 is pivoted at 4a above the table 1 which is removably attached to the machine, and carries a hook-shaped plate 6 which lies under the shoot. On rearward movement of the lever a dog 7 thereon engages a pin 20 on the plunger 18 to withdraw the latter and allow the lowermost bracket to fall on the plate 6, but when the lever is moved forwards again the bracket is prevented from moving by the forward edge of the shoot, and when the hook end of the plate 6 has passed, the bracket falls on a plate 27 and the plunger 18 is returned by its spring to hold the next bracket. A recessed part 4b on the lever 4 then engages the bracket to slide it forwards on the plate 27 and clamp it against an upturned edge 1b of the table 1 where the first hole may be drilled by a drill a<1>. The bracket is held vertically on the plate 27 by rollers 23 on a vertical slide 24 which is yieldingly mounted by means of a volute spring 22. When the lever 4 is rocked rearwardly the hook on the plate 6 slides the drilled bracket rearwardly on the plate 27 until it drops on a plate 33 carried by a lever 3 having a pivoted lost-motion connection 3a with the lever 4. A linkage 8, 10 pivoted to the lever 4 presses on the free end of the lever 3 to cause it to follow the motion of the lever 4 but slightly out of phase on account of the lost-motion pivot. On the next forward motion of the levers 3, 4, an undrilled bracket falls on the plate 27 and the partly drilled bracket is engaged by a recess 3b on the lever 3 to be clamped against a spring stop 28 on the table 1 in position for having the second hole drilled by a drill a<2>, the positioning of the bracket being assisted by a spring-loaded arm 12 having a notch at the end and mounted on a vertical pivot on the table 1. The recesses 3b, 4b in the levers 3, 4 are angularly related as shown in Fig. 4 to position the brackets at the required angle for each hole. On the next rearward movement of the levers 3, 4 a stop 11 on the table 1 passing through a slot in the lever 3 engages the completely drilled bracket to sweep it off the plate 33, and allow it to fall through a notch 1c in the table 1.

Abstract: 455,617. Printing-machines. ELLIOTT, C. J., 9, Sandringham Road, Ainsdale, Southport. April 23, 1935, No. 12147. [Class 100 (ii)] In a multi-colour fabric-printing machine a flexible coupling, e.g. an Oldham coupling f, is arranged between the shaft d of the box-wheel b corresponding to each printing-roller e<1> and the shaft e of the roller e<1>. This arrangement permits of ready adaptation of the position of the rollers e<1> to slight variations in the diameter of the impression cylinder k, and also permits change of rollers e<1> without disturbing the gear connections between the crown wheel a and the box-wheels b. When a new roller e<1> is to be introduced, the shaft d and its coupling fare moved to the right by means of a lever i so as to release the key connection between the part g of the coupling and the shaft e. This can be effected without disconnecting the gears a, b, but by moving the lever i to position II, Fig. 1, the gears are disconnected, thus throwing out the drive to the particular roller e<1>. Circumferential adjustment between the wheels a, b may be effected by means of wheels m, n and brakes o, p by mechanism as described in Specification 435,800. In a modification, the shaft d is connected to the coupling f by means of a toothed coupling comprising a part q which. can be moved axially along the shaft d in order to connect or disconnect the shaft d to the coupling f. Pivoted catches u normally maintain the teeth s, t in engagement, and by releasing these catches and operating the lever i the shaft d can be disconnected from the coupling f. In a further modification, a similar toothed coupling is arranged between the shaft e and the coupling f, and a spring-catch holds this coupling in operative and inoperative positions respectively.
