Title: Wheeled vehicles incorporating hydrostatic transmission window frames and parts therefor
IPC: F04B1/32
Filed: 1973-02-23
Abstract: 1427171 Hydrostatic transmission control; linkwork JOSHUA SHAW & SONS Ltd 23 Feb 1973 8925/73 Headings F2W and F2K In a hydrostatic transmission in which the displacement of a swash-plate pump is varied by a lever 10 acting through a Bowden cable 16 and linkage 33 on a pump displacement adjusting lever 46, depression of a brake pedal 20 acts on the linkage 33 to move the lever 46 to a neutral, zero displacement, position in which the transmission provides hydrostatic braking. The Bowden cable 16 is connected to an arm 33 fast with a shaft 36 to which a plate 34 is secured. The shaft 36 is pivotally carried by a fixed bracket 35. A bell crank 38 is pivoted at 40 on the plate 34. One arm of the bell crank 38 is pivotally connected at 44 to a link 42 which, at its other end, is pivotally connected to the pump displacement adjusting lever 46. The distance between the pivots 36, 40 is equal to the distance between the pivots 40, 44 and the distance between the pivots 36, 48 is equal to the distance between the pivots 44, 48. A tension spring 41 acts between the other arm of the bell crank 38 and the plate 34 to normally hold the linkage in the position shown in which, on actuation of the lever 10, the linkage rotates as a unit about the axis 36 to effect adjustment of the lever 46. With the lever 46 in its forward or reverse displacement position, depression of the brake pedal 20 acts through a master cylinder 26 and slave cylinder 50 to rotate the bell crank 38 relative to the plate 34. The rotation of the bell crank 38 brings the pivot axis 44 into coincidence with the pivot axis 36 and thus moves the lever 46 to its neutral position. Depression of the pedal 20 may additionally actuate wheel brakes.

Title: Stop motion assembly and method
IPC: D04B35/14
Filed: 1974-02-27
Abstract: 1467372 Stop motions for knitting machines M PHILIP 27 Feb 1974 [16 March 1973 5 Feb 1974] 8953/74 Heading D1C A stop motion assembly for a knitting machine is mounted to sense yarn tension between guides G1, G2, Fig. 1, and comprises a housing with chambers 2, 3, 4 containing, respectively, a spiral spring tape 37, a catch and a switch. The tape is wound round an arbor 28, Fig. 3, locked against rotation by a nut 33 and securing the tape inner end. The tape free end 40 projects through a slot 36 in the chamber and carries a holder 41. With ceramic yarn guides 53, and movable between an inoperative position (full lines) and a position (phantom lines) towards a base line joining guides G1, G2. In use, supply yarn Y passes through guides G1, both guides 53 and then guide G3. An arm 47 on the holder co-operaates with the slot 36 to form a stop in the upper position of the tape during normal operation of the machine. The retracting force applied by the tape, which may be of spring steel strips, strand or wire, is adjustable by means of arbor 28. The number of coils remains constant during extension and retraction of the tape, and the extent of extension is limited by contraction of the coils. Movement of the holder from the inoperative position before a predetermined tension is reached is prevented by a catch 59 pivotable in chamber 3 against an adjustable spring 75 and engaging the holder with a nose portion 62 which projects through a slot 70 in the chamber. A yarn sensor 99 pivoted in the switch chamber 4 has its free end 103, Fig. 2, bent in U-form to contact yarn between guides 53. Within the chamber the part 100 of the sensor carries contact 113 which engages fixed contact 97 when the sensor is in the lowest position 99A, thereby to actuate the machine stop motion control circuit and also to illuminate bulb 84 providing a visual signal. The sensor will move to position 99A if the yarn breaks or if the yarn tension rises excessively to pull holder 41 sufficiently far from its inoperative position. The holder is capable of a long travel, so that, if yarn tension rises, the machine can be halted before the yarn breaks. After stopping and correction of the fault causing the excessive tension, holder 41 is restored to its inoperative position and the machine restarted. In a modification (Fig. 6, not shown) the stop motion circuit switch is incorporated in catch chamber 3.

Title: Manufacture of anhydrides of alkoxy-aliphatic acids
IPC: C07C51/56
Filed: 1928-03-24
Abstract: 313,233. Dreyfus, H. March 24, 1928. Alkoxy aliphatic anhydrides.-Alkoxy aliphatic anhydrides or their substitution products are prepared by bringing metallic salts of corresponding acids or mixtures thereof into reaction with sulphur and chlorine or with sulphur-chlorine compounds mixed or not with chlorine. Preferably, the anhydrous pulverulent alkali-metal salts are employed and the reaction is conducted in an inert medium with the use of about six atoms of chlorine for each eight acidyl radicles taken as salt. The inert medium may be the anhydride to be produced, and the process may then be conducted continuously. The anhydrides may be freed from traces of sulphur or its compounds by treatment with suitable metals or metal compounds, such as lead oxide or copper oxide, or by treatment with chlorine and a metal salt of the acid corresponding to the anhydride. In the examples, (1) dry powdered sodium methoxyacetate mixed with methoxyacetic anhydride is treated with sulphur dichloride at 0-10‹ C.; the product is distilled in vacuo when the reaction is complete; (2) a mixture of sulphur dichloride and chlorine is used instead of sulphur dichloride alone; (3) methoxyacetic anhydride containing a little sulphur is treated with sodium methoxy acetate and chlorine; the purified product is distilled off. Reference is made also to the use of sulphur monochloride and to the preparation of anhydrides from the ethyl and propyl ethers of glycollic acid and the methyl, ethyl, and propyl ethers of lactic and hydracrylic acids.

Patent GB-461164-A (GB)
Title: Improvements in or relating to apparatus for racking effervescent or aerated liquids
IPC: B01F3/04
Filed: 1936-03-26
Abstract: 461,164. Bottling. SOC. INDUSTRIELLE DE MACHINES MODERNES AUTOMATIQUES. March 26, 1936, No. 9063. Convention date, Aug. 24, 1935. [Class 125 (ii)] In apparatus for filling bottles with effervescent or aerated liquids in which the liquid level in the liquid distributing vessel 1 is maintained substantially constant by the introduction of air or gas under pressure, the pressure in the vessel is regulated by a valve 15 disposed in a conduit 151 communicating with the compressed air or gas supply tube 8, the valve 15 being controlled by a piston 12 which is exposed to the pressure of the air or gas in the vessel 1 and is so weighted that it will open at a pressure slightly exceeding the working pressure of the vessel 1, when that pressure drops below normal and so limit the pressure drop in the distributing vessel and prevent the formation of foam and loss of gas by the liquid being bottled. As shown, the valve 15, with its piston 12 and valves 13, 16 with their pistons 10, 11 respectively, are housed in a casing 4 on the top of the vessel 1, the pistons being grooved to permit equalization of the pressures on the tops and bottoms thereof. The liquid is supplied to the vessel 1 by a tube 2 opening near the bottom of the vessel and a float 3, controlling the liquid level in the vessel, is formed with a sleeve 3<1> adapted to coact with a beam 21 pivoted on the tube 2 with its arms disposed below the stems of the valves 13, 16. The gas or air supply pipe 8 opens below the piston 16 and the valve 13 communicates with an exhaust valve 14, and under normal working conditions the valve 15 remains closed but opens to admit compressed air or gas when the pressure falls slightly in the vessel if the pressure drop is considerable, the float 3 will rise and cause the beam to bear against the stem of the valve 13, and then to pivot about its axis and bear against the stem of the valve 16 which, being held on its seat by the pressure of the air or gas supply, stops the pivoting of the beam and causes the valve 13 to close and prevent escape of air from the vessel 1 until the normal liquid level is restored in the vessel. In the event of a bottle bursting or a leak occurring, the beam 21 is raised quickly by the float and first closes the valve 13 and then, bearing against the stem thereof, opens the valve 16 which admits the compressed air or gas into the vessel and restores the normal working pressure.

Title: Means for Controlling Electric Motors.
IPC: H02P1/20
Filed: 1916-06-28
Abstract: 102,889. Igranic Electric Co., (Cutler-Hammer Manufacturing Co.). June 28, 1916. Master control systems.-In a system of control for an electric motor by electromagnetic contactors, the line contactor and the first accelerating-contactor have shunt operating-windings with circuits completed through a hand-controller, and the other accelerating-contactors have series operating-windings. In addition to the operating- coils 9, the accelerating-contactors 4, 5 have series lock-out coils 10, and the circuit of the shunt coil 11 on the first accelerating- switch 3 can only be completed through the auxiliary contact 13 on the line contactor 2. When the hand-controller 6 is moved to its first position, the coil 12 is energized and the line contactor 2 is closed to connect all the resistance in circuit with the motor. The motor circuit includes the winding of the relay 7, and the relay contacts are opened when the motor current reaches an excessive value. When the hand-controller is moved to its second position, the circuit of the coil 11 on contactor 3 is completed, subject to the control of the relay 7. The contactor 3 cuts out the resistance section R, and the contactors 4, 5 follow automatically to cut out resistance sections R', R<2>. When the motor is suddenly reversed, the contactors open, and the relay 7 prevents the contactor 3 from closing until the current drops. In a modification, the series relay 7 is omitted, and the contactor 3 is provided with a series lock-out coil. The arrangement may be further modified to provide for additional speeds, series contactors being employed to give automatic acceleration from one speed to the next higher speed.

Title: Aircraft tank vent valve
Inventor: KSIESKI KAZIMIERZ T
IPC: F16K17/194
Filed: 1955-03-30
Abstract: 775,513. Venting fuel tanks in aircraft. AERO SUPPLY MFG. CO., Inc. March 30, 1955, No. 9303/55. Class 4. [Also in Group XXIX] A vent valve for a fuel tank comprises float-actuated valve means for venting the tank in a normal horizontal position and gravity-actuated means for holding the valve means closed when the tank is inverted. The vent valve may also have means active under centrifugal force for holding the valve means closed. When the float 39 is lowered it turns a lever 29 hinged at 31 so that valves 27, 28 move up and down respectively to vent the tank through the pipe 21. Should the tank become inverted a bent arm 43 carrying a weight 44 and hinged 31 moves to contact a pin on the member -29 and closes both valves. A further arm 49 pivoted at 31 and carrying a weight 50 moves to the right under centrifugal force to contact the pin and close both valves thus preventing a surge of liquid escaping into the vent pipe. The valves 27, 28 may be replaced by a double beat lift valve or a combined lift and piston valve moving over a ported cylindrical seat. The valve 28 may have its seat carried by a dished washer spring to compensate for bending of the member 29 under load, while the valve 27 may be a lift valve combined with a surrounding flexible seat member so that when the lift valve first opens the pressure acts upon a larger area to give quick movement to full opening. The hinged valves may be balanced, or unbalanced to open on excessive pressure when the float is immersed. A lightly loaded hinged check valve 58 on housing 20 opens into the tank if the tank pressure falls.
