Title: Improvements in or relating to the Manufacture of Knitted Footwear
Inventor: COLTON LEWIS HENRY
IPC: D04B9/46
Filed: 1967-07-08
Abstract: 1,172,294. Seaming non-metallic sheet material. L. H. COLTON. 1 July, 1968 [8 July, 1967], No. 31525/67. Heading B5K. [Also in Divisions A3 and D1] The toe of a stocking knitted of a thermoplastic yarn is closed by fusion. This is performed on a circular knitting machine by providing a pair of grippers 13 which on completion of the knitting are projected within the normal take-down tube 7 to constrict and grip the tubular fabric. The continued rotation of the needle cylinder causes the tubular fabric still held by the needles to become twisted about itself as at 33 until the upper end 34 of the twisted portion abuts against a heater member 28. The element of the member 28 having been connected to a low-voltage supply, contact of the end 34 of the twisted portion 33 with the heater member 28 causes the thermoplastic material to fuse together at this point providing an effective closure of the toe. Alternatively a heater member may be positioned on each of the gripper members as at 35, Fig. 3, so that gripping of the tube by the grippers also causes contact of the thermoplastic material with the heater members on the grippers and consequently fusion of the material to close the toe.

Abstract: 910,497. Latches. CHICAGO FORGING & MANUFACTURING CO. Sept. 1, 1961 [Sept. 1, 1960], No. 31552/61. Class 44. A latch assembly comprises a latch plate and a movable plunger 12 provided with a spring- loaded pivotally mounted latch 26 which is arranged to move outwards from the plunger and hold it in the latch plate after the plunger has penetrated an aperture in the latch plate, and which the latch includes a control element 20, arranged to make sliding contact with a slide surface 68 lying adjacent a latch-release member pivotally mounted on the plunger 12. As shown, the surface 68 is formed by a flange of a guide member 66 pivotally mounted on the plunger and pivots with a safety hook 46 and the release member, which latter forms part of an actuating arm 58 and includes an abutment portion 62 for the control element 20 and the latched position of the latch 26. The latch, which is pivotally and slidably mounted on the control member 20 is retained in its latched position by the engagement of a pin 44 in a serrated slot 40. The arrangement is such that rotation of the arm 58 to free the latch, moves the abutment 62 out of the path of the control member 20 which during the return movement of the latch 26, after it clears the latch plate, slides on the surface 68, which is preferably moved out of the path of the control member 20 as it moves inwardly when the plunger 12 is pulled out of the latch plate.

Title: Improvements in or relating to bag filters for cleaning air
IPC: B01D46/04
Filed: 1928-10-31
Abstract: 314,297. Masehinenfabrik Beth Akt.-Ges. Oct. 1, 1928, [Convention date]. Addition to 281,994. Filtering. - A conduit 19 is arranged between the air exit of the auxiliary group of filters IV, which cleans the counter current of air, and the exhaust duct 10 for the cleaned air of the main filters I-III. The - conduit may contain a valve 20 opened and closed in accordance with the admission of air to clean the filters. Dusty air enters through valves 14 and passes into and through the filter bags. The dust retained is shaken off into hoppers having valves 18 by which it is discharged into a channel with a conveyer 5 when air is supplied to clean the bags. The valves 15 which control the exits from the working compartments are actuated through linkage by cam discs on a shaft 35. The fresh air inlet valves 17 are actuated through a lever 32 having a forked end engaged by a cam 34 on a shaft 27 when the lever is raised by a cam 36 engaging a stop on the lever. Simultaneously, the lever 32 rotates arms 29, 30, causing the counterweighted valve 20 to open the outlet 19 and removing the supporting arm 30 from a point of support 31 on a lever 26 which carries a set of filter bags. These bags are thus allowed to collapse and are shaken by tappets 28 on the shaft 27, which engage the lever 26. An arm 23 is provided for each working compartment, hooks 24 engaging these arms so that the common valve 20 can be opened when any compartment is being cleaned.

Title: Power plant including a supercharged compression ignition engine having exhaust recirculation
IPC: F02N19/06
Filed: 1975-07-28
Abstract: 1485713 Supercharged I C engines; recirculating exhaust gases FRANCE ARMED FORCES MINISTER OF 28 July 1975 [1 Aug 1974] 31575/75 Heading F1B [Also in Division F2] Exhaust gases are recirculated from the downstream end of a combustion chamber 9 to the intakte duct 21 of a compressor 2 driven by a turbine 3 receiving exhaust gases from the combustion chamber. The compressor supplies air to the working chambers 6 of the compression ignition engine 1 and to the chamber 9 which receives exhaust gas from the chambers 6 and fuel from a supply 10. The flow of exhaust gases through the recirculation duct 18 is controlled by a valve 22 which is controlled automatically or by an operator to close the duct when the conditions of air entering the engine after starting permit compression ignition without heating by addition of exhaust gases. A throttle valve 11, e.g. a flap or plug valve, in the combustion chamber air supply passage 15 is operated by a differential piston arrangement 12 to provide a pressure drop in the passage. The valve 22 includes a poppet valve 27 co-operable with a seat 24 and a piston valve 26 controlling bores 20 communicating with the duct 21. A temperature responsive element 30 positions a member 29 connected to the valve rod 31 by a spring-loaded lost-motion connection 28, 32, 33 which permits the rod to move relative to the member. The element responds to the air temperature in the duct 21 or engine coolant temperature and tends decrease the number of bores 20 which are open as the temperature increases. The piston 26 is subject to the exhaust gas pressure and above a predetermined pressure moves relative to the  member 29 against the bias of the spring 28. The valve 27 when adjacent its seat has a pressure drop thereacross and it rapidly engages its seat to prevent further exhaust recirculation. The compressor 2 may be supplied by a low-pressure compressor 39 driven by a turbine 40 receiving exhaust gases from the turbine 3. The engine may be a two or four-stroke reciprocating piston engine or a rotary piston engine.

Abstract: 1,040,754. Control of A.C. motors. GENERAL ELECTRIC CO. Ltd. March 29, 1963 [Aug. 17, 1962], No. 31705/62. Heading H2J. [Also in Division G1] In apparatus for transmitting angular position or motion, currents dependent upon the output voltage from a transmitter are supplied to the stator windings of a receiver, each winding constituting a separate current path, and the stator currents being rectified currents derived directly from the single phase A.C. supply to the transmitter. As shown, the output voltages between pairs of terminals of transmitter 1 are used to control the firing angles of semi-conductor controlled rectifiers 24 (only one shown), the rectifiers each being in series with source 11 and one of the stator windings of receiver 13. Motor 12 drives the rotor 2 of magslip 1 at a speed equivalent to less than one twentieth of the A.C. frequency. The output between terminals 6 and 7 is applied to transformer 32, while an alternating voltage in phase quadrature to the supply at 9, 10 is applied to transformer 33. The secondaries of the transformers are connected in series with a pulse generator 25, which produces a pulse whenever terminal 28 becomes positive relative to 29. Rectifier 24 is thus triggered. The firing angle depends on the position of rotor 2, and the sensitivity of the circuit depends on the ratio of the amplitudes of the voltages generated in the secondaries of transformers 32, 33. It is stated that the system can be modified so that the current direction in the receiver windings depends on the phase sense of the output between the terminal pairs such as 6, 7.

Filed: 1929-10-21
Abstract: 340,076. Glass manufacture. DICKER, S. G. S., 20, Holborn, London.-(Naamlooze Vennootschap Maatschappij tot Exploitatie van Uitvindingen, 67, Wynhaven, Rotterdam, Holland.) Oct. 21, 1929, No. 31935. [Class 56.] Drawing ; forming tubes and rods.-Relates to the method of making glass tubes or rods in which cylindrical blocks of glass are threaded on a mandrel, or piled in a tube, the lower end of the mandrel or tube being shaped to support the blocks. The lower end of the pile is heated, and the glass flows downwards and is drawn away by suitable mechanism. According to the present invention, the mandrel or tube is rotated continuously to secure a more regular distribution of the glass. In the apparatus shown in Fig. 1, the glass blocks 11 are inserted in the upper end of an inclined tube 10 which is supported by rollers 15, 16 and is provided with a gear wheel 17 by which it is rotated. The lower end, 12, of the tube is constricted to support the blocks, and it is heated by burners 13. The blocks are shaped as shown in Fig. 2 so that they centre one another when piled, and they may have a central aperture 14 through which air may be blown to maintain the bore of the glass tube as it is formed. The aperture may be dispensed with, the lower end of the holder 10 being formed as a bulbous enlargement so that the molten glass spreads along its sides and forms a tube at the outlet. In the construction shown in Fig. 3, the holder consists of a tubular mandrel 20 supported by three bearings 21 which are spaced apart so that glass blocks can rest between them. Each bearing consists of a pair of pivoted jaws, and the upper jaw of a pair carries gear wheels which transmit the rotation of a driving-shaft 40 to gear teeth formed on a reduced portion of the mandrel. The jaws can be opened to allow a glass block to slip down the mandrel, and by using three of these bearings, the mandrel is constantly supported and rotated. In the construction shown in Fig. 6, a mandrel 50 is supported by a bearing 51 and driven by a pinion 52. Each of the glass blocks 53 is made in two halves, as shown in Fig. 7, and to hold them together the mandrel is surrounded by a rotatable tube 54 which is heated by a burner 55 to fuse the blocks together.
