Title: Improvements in or relating to knitting machine
IPC: D04B9/10
Filed: 1937-05-28
Abstract: 483,360. Knitting - machines. SCOTT & WILLIAMS, Inc. May 28, 1937, No. 14906. Convention date, July 24, 1936. [Class 74 (ii)] To permit all the yarn fingers to occupy substantially the same feeding position, as well as to introduce the yarns at substantially the same needle, means are provided to maintain a yarn in substantially normal feeding relationship with the needles as a yarn finger is being withdrawn from feeding position. These means comprise movable blocking pins 111, 112, the end of the upper pin 111 being disposed radially outward of the end of the lower pin 112. A hooked finger 122 for placing the ingoing yarn in position to be readily -taken by the needles, a yarn guard 113, main yarn-clamping means 89, an auxiliary spring yarn clamp 96, and a yarn-cutter 85, 86 are also provided. In operation, the outgoing yarn finger 4 is partly withdrawn before the ingoing yarn finger 5 is inserted, and the yarn of the withdrawn finger is engaged and held by the lower blocking pin 112 so that it can be taken by the needles. The ingoing yarn, stretching from the main clamp 89 to the finger 5, is engaged by the hooked finger 122 and presented to the needles. To permit this, the pin 112 has been lowered, and the outgoing yarn is caught by the upper pin 111 which allows it still to be taken by the needles. The yarn-changing operation is completed by the raising of the upper pin 111 to release the outgoing yarn, the complete withdrawal of the yarn finger 4 and the raising and withdrawal of the hooked finger 122. As shown in Fig. 3, the yarn fingers 1 .. 5 are guided in slots 40 in a plate 56 so that in feeding position the yarn-feeding ends occupy substantially the same position. The fingers 1 .. 5 are moved into operative position by springs 18, Fig. 1, and into inoperative position by levers 12, 13. The levers 12, 13 are actuated by members 23 mounted upon the bracket 6 carrying the yarn fingers. Levers 37, one to each member 23 are mounted upon a frame 32, reciprocated once for each revolution of the machine, and can be swung about their pivot to engage latches 48 on the members 23 by a cam member 55. The cam member 55 is mounted upon a lever 46 and is controlled by stops 73 of a pattern chain 72 so as to be brought into register with either of the levers 37. Reciprocation of the frame 32 serves also to actuate the pins 111, 112, the hooked finger 112 and the yarn clamping and cutting means. The frame 32 carries a rod 31 which engages a lever 104, one arm 108 of which operates through a lever 98 and stop pin 100, the clamp and cutter operating lever 93. A second arm 142 of the lever 104 engages a lever 138 to rock the lever 128 controlling the hooked finger 122. A third arm 117 operates the pins 111, 112. The yarn clamp 89 is faced with leather which bears against a serrated plate. The leather facing sinks into the serrations and crinkles the inactive yarns to hold them more positively.

Title: A device for controlling at a distance
IPC: F15B11/072
Filed: 1933-05-25
Abstract: 412,756. Pneumatic relays &c. MESSIER, Y. L., 179, Boulevard Brune, Paris. May 25, 1933, No. 15105. Convention date, May 27, 1932. [Class 8 (ii).] A distant-control device comprises a controlling distributer A receiving fluid under pressure, and allowing the flow of this fluid towards a receiving regulating device B, Fig. 1, or towards a relay C, Fig. 2, controlling a such receiving regulating device. The distributer comprises a loaded double-headed valve 3, upon which acts a control rod 7 having an interior channel 8, which communicates with the atmosphere, and which is obstructed on the inner side when the rod encounters one of the heads of the valve. As shown in Fig. 1, on depressing the knob 6, the end of the hollow control rod 7 first abuts against the end 9 of the valve 3, thus closing the passage 8, and then opens the valve 3, so that compressed gas from the inlet pipe 5 passes through the pipe 11 to the cylinder 13, and so pushes the pistons 17, 18 and operating rod 16 to the right. To damp the movement of the rod 16, liquid is forced through orifices 19 in the diaphragm 14 by the pistons 17, 18, the orifices 19 in the diaphragm 14 by the pistons 17, 18, the orifices being automatically adjustable in size to compensate for changes in the viscosity of the liquid due to changes of temperature. In the form shown in Fig. 2, the pipe 11 is connected through a non-return valve 31 to a chamber 35 containing a double piston 26, 27 having a bore 28 and adapted to actuate the relay valve 22. On depressing the knob 6, compressed gas is supplied by the valve A to the chamber 35, thus depressing the piston, opening the valve 22, and admitting air from the pipe 24 to the pipe 36, which is connected to the actuating cylinder 13. On releasing the knob 6, the pressure supply is cut off from the chamber 35, and, as the piston 26, 27 rises slowly under the action of a spring 38, the gas is expelled through a restricted orifice 33, the gas in the actuating cylinder being finally exhausted through the passage 28 and port 29. The invention is stated to be particularly applicable to releasing weapons on aircraft.

Title: Improvements relating to railway track circuit apparatus
IPC: B61L23/16
Filed: 1942-10-30
Abstract: 564,800. Electromagnetic relays for railway tracks. TOMLINSON, A. V. (Union Switch & Signal Co.). Oct. 30, 1942, No. 15269. [Class 105] [Also in Group XXXVII] When a train enters or leaves a section 1, 1a, the sudden change of current in the coil 7 of an induction relay rotates a conducting vane 8 which passes between the poles of a permanent magnet 20 so that' this rocks about its axis 21 and operates contacts 24, 25. A slow rotation of the vane 8 due to change in resistance of the track because of rain, for example, will cause no movement of the magnet 20. When the coil 7 is energized, the vane rotates into a position such as that shown against the action of a biassing weight and closes other contacts 14, 15. In the form shown, this rotation of the vane will cause a momentary clockwise rocking of the magnet 20 so that contacts 23, 24 are closed momentarily, actuating a relay TRS with a maintaining circuit which is later broken when contacts 25, 26 are separated by the counter-clockwise rotation of the magnet 20 due to the release of the vane 8 due to the de-energization of the magnet 7 due to a train entering the section. In a modification, Fig. 3 (not shown), the magnet 20 is retained in its displaced position by a dead-centre snap device.

Title: Improvements in or relating to hydrocarbon synthesis
IPC: C07C1/04
Filed: 1949-06-09
Abstract: A process of synthesizing hydrocarbons, oxygenated hydrocarbons and mixtures thereof from CO and H2 in the presence of a fluidized iron catalyst, wherein a stream of reactant gas containing a substantial proportion of H2 and CO is passed in contact with said catalyst under predetermined conditions of reaction, including an elevated temperature effective to form such products, a substantial portion of the CO is converted, and the products are withdrawn from contact with the catalyst, is characterized by regulating the time of contact between the reactant gas and the catalyst so that the withdrawn stream of products contains between about 1 and 3 per cent by volume of CO, and recovering the products from the withdrawn stream.  Within the stated range it is preferred that the product stream contains not less than about 2 mol. per cent of CO. Advantageously the total mol. per cent of CO in the feed is not substantially greater than about 15 per cent of the total gas feed and is preferably not less than about 5 mol. per cent greater than that in the effiuent.  The water content should be as low as possible and not greater than 3 mol. per cent. Preferably the feed contains an H2 : CO ratio of substantially above 2.5 : 1, preferably above 3 : 1, e.g. 4 or 5 : 1.  Preferably upwards of about 15 per cent of CO2 should be present.  Inert gas diluents may be used and gaseous reaction products recycled. Temperatures, pressures and catalysts usual in the art are employed.  Aliphatic alcohols, organic acids, ketones and aldehydes are mentioned as oxygen-containing compounds produced. In an example the catalyst is iron powder with K2O and Al2O3 promoters and is conditioned prior to reaction, the feed is about 30.6 per cent CO, about 64.3 per cent H2, the remainder being CO2, CH4 and N2, reaction is at 650 DEG  F. and 250 p.s.i. with a linear gas velocity of 1.2 feet per second, and the effluent gases contain about 2.3 per cent of CO, the contact time being approximately 25 seconds and the products liquid hydrocarbons. In a comparative illustration reaction is effected to give effluent gases containing about 0.7 per cent CO and in a further example, a portion of the effluent, after product separation, is recycled to the fresh feed in a ratio of 1 : 1 and the combined feeds treated as in the first example.

Title: Improvements in or relating to thermionic valve amplifying circuits
IPC: H03F3/02
Filed: 1937-06-05
Abstract: 496,883. Valve amplifying circuits. BLUMLEIN, A. D. June 5, 1937, No. 15620. [Class 40 (v)] Pentodes or power tetrodes which normally have a high internal impedance have their impedance reduced, so that they may be more nearly matched to their optimum loads and so that the danger of an excessive increase of anode voltage on removal of the load may be avoided, by connecting the screening electrode to the anode or output circuit in such a manner that its potential varies in phase with, but at a lower amplitude than, the potential of the anode. The screening grid 13 of the pentode valve is connected to a tapping on the primary 11 of the output transformer so that the potential of 13 varies in direct proportion to the potential of the anode 10. The tapping point may be so arranged that the voltage swing on the screen grid 13 is between about a quarter and a half the voltage swing on the anode 10. If the decoupling condenser 8 on the bias resistance 7 is not employed so that negative feedback tending to reduce second harmonic output is produced, the impedance of the valve will be increased. In this case the potential variations of the screen are made greater in order to maintain the anode impedance at the required value. Instead of connecting the screen directly to the output transformer it may be fed through a resistance from the H.T. source and connected to a tapping in the output circuit through a blocking condenser.

Title: Improvements in and relating to internal combustion engines having liquid-fuel injection means
IPC: F02B71/04
Filed: 1936-06-05
Abstract: 476,386. Regulating oil engines. PESCARA, R. P. June 5, 1936, No. 15795. Convention date, June 5, 1935. [Classes 7 (iii) and 7 (vi)] In engines with variable compression space, particularly free-piston engines combined with compressors, the distribution of the injected liquid fuel is varied automatically in accordance with alterations in the volume of the compression space, for example by alteration of the number, angle, shape, or mutual position of the injection jets. Fig. 1 shows an engine with free opposed pistons 22 having between them a compression space 1 provided with two or more fuel injectors 2<1>, 2<2> fed by pumps 5<1>, 5<2>, the amount of fuel delivered being varied, for example by variable byepasses to the pumps, in accordance with the varying size of the chamber 1. The variation in fuel injection may be obtained by cutting out one or more of the pumps. A piston 6 acted on by the air-intake pressure may control the pumps through racks 4<1>, 4<2>. The distribution of fuel injection may be varied by providing fan-shaped injections from an injector device which can be rotated about its axis so that the plane of the fan is normal or parallel to the cylinder axis, or in some intermediate position, in accordance with the size of the chamber 1. Fig. 5 shows such an injection device, the injector 2<1> being rotatable within a plug 2<0> by an arm 7. In another form, the angle at which the jets are directed across the cylinder may be varied by rocking the injectors sideways. Fig. 8 shows an injector 13 with a spherical tip 15 pressed by a spring 29 against a seating 28, the inclination of the jet 3 being varied by tilting the stem 13 to one side by a link 7, or by a projection 11 attached to one of the pistons 22. In another form, the fuel injectors are arranged opposite one another in the piston heads, and the fuel pump is carried by one of the pistons and actuated by engagement with an adjustable stationary cam. In engines where a constant compression space 1 between the opposed pistons communicates with an auxiliary variable compression space, the fuel injectors supplying the latter space are adjusted. In a further form, the shape of a whirling jet of fuel is varied, e.g. as shown in Fig. 13, where the fuel traverses helical grooves 19 in a member 20 which is axially adjustable in relation to its seating.
