Title: Hydraulic system
IPC: F15B13/04
Filed: 1962-06-12
Abstract: 959,622. Fluid-pressure servomotor control systems. NEW YORK AIR BRAKE CO. June 12, 1962 [July 13, 1961], No. 22588/62. Heading G3P. A remote valve 11, Fig. 1, movable into any one of the "float", "lower", "neutral" or "raise" positions by a manual lever 147, controls the movement of a relay valve 12 into any one of four corresponding positions, which relay valve is connected to an hydraulic motor M. With the lever 147 in the neutral position fluid from a small pump P2 flows from relay valve inlet port 102, Fig. 3, to the associated sump port 103 via passage 111, a spool groove 119 and a restricted channel 125 in spool land 122; the back pressure generated by the channel 125 fluid also causes fluid to flow from groove 119 to one chamber 61, Fig. 4, of the differential area motor piston 56, the cylinder 54 of which is connected to the spool valve 27, Fig. 1, of the relay valve 11. A second flow path from passage 111, Fig. 3, also leads to sump port 103 via spool groove 118 and another restricted channel 124 in land 122 whereby the back pressure produced by the latter is conducted by groove 106 to the other chamber 59, Fig. 4, of the piston 56, the pressures across which are equal and of low value so that the cylinder 54 is held in the central position by spring 86; the lands 121, 123, Fig. 3, or the channels 124, 125 may be arranged to compensate for the differential area of the piston 56, Fig. 4. Port 102, Fig. 3, also communicates with a chamber 132 to urge a 'feel' piston 133, to its leftward extremity; a spring 138 preloaded to balance the force developed by the fluid in chamber 132 at idling pressure holds the remote valve spool 117 in the neutral position. Upon moving the spool 117 to the right into the 'raise' position against spring 138 the length of the restricted channels 125, 124 increase and decrease, respectively, so creating a pressure differential in chambers 59, 61, Fig. 4, whereby the cylinder 54 and relay valve 27 are moved to the extreme leftward position against spring 86 so that an inlet port 14, Fig. 1, open to a large capacity pump, is connected via a motor groove 22 to the motor 14, the fluid exhausting therefrom being conducted to a sump port 15 by a groove 17. When the lever 147 is released the spring 138, Fig. 3, returns the spool 117 to the neutral position whereupon the spool 27, Fig. 1, moves correspondingly. Movement of the spool 117, Fig. 3, to the left into the 'lower' position is opposed by the force of the fluid in chamber 132 so providing 'feel', and still further leftward movement of the spool 127 to the 'float' position is opposed by springs 74, 75 as well as spring 86; in this latter position the spool 117 is located by balls 143 engaging grooves 148. In a modification, the remote valve spool 117 is spring centred in both directions and the hydraulic 'feel' device is only operable beyond the 'lower'position.

Patent GB-1526503-A (GB)
Title: Integrated circuit device including both n-channel and p-channel insulated gate field effect transistors
IPC: H01L27/08
Filed: 1976-06-03
Abstract: A complementary integrated circuit in MOS technology contains at least one P-channel FET (18) with insulated gate (24) and one N-channel FET (16) with insulated gate (26). A closed geometry results in fast transistors with a high packing density. Drain zones (38 and 42) are surrounded by frame-like gate structures (24 and 26) which, in turn, are surrounded by source zones (40 and 44). To insulate the transistors, a layer (22), which is also closed in the manner of a frame, of conductive material is provided which acts as insulating gate. This also results in space-saving isolation of the transistors. In production, a self-aligning gate technique is used, the layer (22) being produced at the same time as the gates (24, 26). A single mask setting can be used for making a plurality of diffusions. <IMAGE>

Abstract: 378,208. Moulding balls &c. SKELTON, E., 26, Raymouth Road, and LONG, E. S., 89, Grange Road, both in Bermondsey, London. Aug. 14, 1931, No. 22972. [Class 87 (ii).] In methods for moulding plastic materials, such as indiarubber, guttapercha, &c., involving the production of a spewed-out fin, the whole or greater part of the fin is used for holding the article during separation from the mould. An apparatus for making balls comprises a two-part mould d, d mounted on platens c of a fixed upper head a and a lower movable head b of an hydraulic press. The half-moulds d are pressed together passing through apertures in the halves of a two-part plate f, f so that the halves f and the halfmoulds d have a common plane of partition. The half-moulds may be chamfered and the halves f formed with complementary lips and concentric recesses j to receive the spewed-out fin. The halves f are then secured by clamps q and the head b and half-moulds d lowered. The head b rides along rods m so arranged with rods k that the two-part plate is also lowered to an intermediate position, Fig. 2, where the articles are suspended by the fins. Tubular knives y mounted on frames x running on rails ware then brought into position between the articles and the heads a, b, and by raising the head b the knives may be moved together to sever the fins. The articles then drop on to false bottoms such as rods z in the lower knives. If severance is incomplete, spring presser bars 11 urge the upper knives further down. The knives may be blunted so that severance is always effected through the bars 11. The knives may overlap in pairs or the upper series may be replaced by anvil elements or rotary knives or other cutting means may be used. For placing the articles initially in position in the lower half-moulds, a frame s may be provided carrying a tray t having apertures adapted to accommodate the articles and retain them by spring fingers u. The loaded frame may be swung round on a pivot to a position over the moulds, and a spring plate v may then be depressed to force the articles through the apertures into the moulds. The frame s may be dispensed with and the tray t slid directly into position. Heating or cooling media may be circulated through the halfmoulds.

Title: Production of primary alcohols
Inventor: DEAN FRED
IPC: C07C29/132
Filed: 1967-05-22
Abstract: 1,213,822. Primary alcohols. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 May, 1968 [22 May, 1967], No. 23673/67. Heading C2C. [Also in Division C5] A plurality of primary alcohols differing in carbon contents are produced by reacting a paraffinic hydrocarbon feed, rich in C 6 , C 7  and C 8  paraffinic hydrocarbons and being an aromatics-free by-product stream from a process for aromatizing naphtha to produce aromatic hydrocarbons, with molecular oxygen to produce a mixture of secondary and/or tertiary alcohols, reducing any hydroperoxide present in this alcohol mixture dehydrating the secondary and/or tertiary alcohols to produce corresponding olefins and converting the olefins to primary alcohols by reaction with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst. The paraffinic hydrocarbon feed may be oxidized at 100- 150‹ C. in the presence or absence of a catalyst or of an initiator e.g. tertiary butyl hydroperoxide. Hydroperoxides present in the oxidation product are reduced to epoxides with an olefinic compound having 2 to 25 carbon atoms in the presence of an epoxidation catalyst. These epoxides may be removed or reduced to the alcohol, while any acids, ketones and esters present are converted to alcohol by vigorous hydrogenation.

IPC: B05B9/01
Filed: 1970-05-15
Abstract: 1,272,530. Spray guns. SPRAYING SYSTEMS CO. 15 May, 1970 [15 May, 1969], No. 23683/70. Heading B2F. [Also in Division F2] In a spray gun the barrel has formed therein a chamber 26 having a fluid supply means 16, a nozzle supply seat communicating with the nozzle, a fluid return seat 32, communicating with a fluid return line 19, valve means 38, 39 spaced apart and fixed to a moveable member within chamber 26 in such a manner that when valve means 38 seats against the nozzle supply seat the valve means 39 is spaced from seat means 32 and vice versa said moveable member communicating with the valve actuating means. The valve means 39 may be tapered so that the flow through return line 19 is variable according to the position of valve means 39 relative to seat means 32. A second chamber 36 is sealed with a seal 37 through which the moveable member is slideably fitted. Contained within chamber 36 is a piston 45. The part of chamber 36 to the rear of the nozzle communicates with chamber 26 via orifices 43, 44 and an interconnecting passage in the moveable valve member. The area of piston 45 is such that the pressure on it substantially counteracts the pressure on valve means 39 when fully seated against seat 32. As shown in Fig. 7 a stop mechanism is provided on the trigger of the gun. This mechanism comprises a stop element 49 slidably mounted on rod 47a (the rear end of rod 15) having flat faces 50, 51 on which is mounted a knurled edge 54. In the position shown in Fig. 7 the flat faces 50 and 51 pass between the flanges 52, 53 on which the trigger is mounted, allowing the trigger to be fully pulled back. Using the knurled edge 54 the element 49 may be rotated through 90 thereby blocking the motion of the trigger.

Title: Improvements in or relating to high frequency receivers
IPC: H04L27/14
Filed: 1930-08-08
Abstract: 347,984. Wireless receiving systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Aug. 8, 1930, No. 23862. Convention date, Aug. 20, 1929. [Classes 40 (iii) and 40 (v).] In order to eliminate the prolongation of telegraphic signals at the receiver due to " echo effect " marking and spacing frequencies are transmitted, the receiver being capable of separating the two frequencies which are separately rectified and fed to indicating or recording means in such a manner that the first portion of each marking and spacing period actuates the recorder in opposite directions. The Figure shows a receiver in which the marking and spacing frequencies are separated by filters 1, 2, separately rectified at 3, 4, and passed through transformers 5, 6, to further rectifiers 7, 8, the bias on which is such that anode current is prohibited with no signal on the grid. Thus the initial portion of a marking signal from 1 closes the upper contacts of the relay 11, which contacts remain closed until the start of the spacing signal from 2, when the lower contacts are closed. By this means the length of the marking and spacing periods transmitted is faithfully reproduced at the receiver. The condensers 14 . . 17 makes the transformers 5, 6 selective between signal frequencies and higher frequencies due to echo phenomena. In addition, amplification may be reduced after the arrival of each marking or spacing signal and increased when the next signal arrives ; also the receiver amplification may be varied inversely with incoming signal amplitude.
