Title: Improvements in or relating to circular independent needle, type knitting machines
IPC: D04B9/46
Filed: 1946-01-02
Abstract: 606,361. Knitting-machines. HEMPHILL CO. Jan. 2, 1946, No. 156. Convention date, Jan. 3, 1945. [Class 74(ii)] The wrap head of a circular independent needle machine is shogged in each direction during reciprocatory knitting so that the wrap fingers wrap yarn round the same needle or groups of needles at positions the same distance ahead of the knitting point in each direction of knitting. As described the wrap spindle comprises a shaft 1 upon the lower end of which is mounted the wrap head 2 having fingers 3 adapted to be projected across the needle circle by cam mechanisms 34. Surrounding the shaft 1 is a sleeve 4 rotated by gearing within the housing 5. A sleeve 6, slidably mounted on the sleeve 4 and keyed thereto, is provided with a slot 12 which engages a pin 9 protruding through the sleeve 4 from the shaft 1. The bottom of the sleeve 6 is provided with an annular channel 13 accommodating blocks 14 on a pivoted yoke 15 connected by a rod 18 to a cam follower. The follower is allowed to follow the contour of the cam during reciprocating knitting only and in so doing it raises or lowers the sleeve 6 for each direction of knitting. This movement, irrespective of the normal rotary motion of the shaft 1, allows the shaft, relative to the sleeves, to position the wrap fingers so that they wrap the same needle or needles at the same distance ahead of the knitting points for each direction of movement. An adjustable slotted plate 59 is attached to the sleeve 6 so that the effective length of the slot 12 may be altered to vary the shogging of the shaft 1. The wrap finger cam mechanism 34 is mounted on a plate 32 secured to a bracket 48 pivoted to the carrier ring 33 and held by a pivoted arm so that the mechanism is prevented from fouling the wrap fingers when the carrier ring and mechanism are raised. Specification 601,676 is referred to.

Title: Improvements in and relating to refrigerating systems
IPC: F25B5/04
Filed: 1948-01-05
Abstract: 639,691. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 5, 1948. No. 321. Convention date, Jan. 4, 1947. '[Class 29] [Also in Group XXIX] In compression systems having two evaporators 1, 2 operating at different temperatures, a pressure-operated valve 7 is provided for selectively connecting one or other of the evaporators to the suction line 6, in response to the difference of pressure in the evaporators, the actuation being modified by an auxiliary pressure-actuated valve 36 after a pre-determined pressure has been attained in one of the evaporators. The high temperature evaporator 2 is supplied with liquid refrigerant from the condenser 4 through a capillary tube 5 and has a suction header 10 from which liquid refrigerant is supplied through a further capillary tube 11 to the low temperature evaporator 1 having a suction header 12. Suction pipes 9, 8 from the headers 10, 12 are connected to the valve casing 7 from which the pipe 6 leads to the suction side of the compressor 3. A piston valve 26 in a valve chamber 20 is subjected on its opposite sides to the pressures in the two evaporators through passages 23, 24 in the casing 7, and is connected by a shaft 30 with a second piston 29 with a groove 41 and rubber buffers 31 which cushion its impact and provide a space between it and the end of the chamber 20. A spring 33 normally forces the piston 26 towards the left, placing the low temperature evaporator suction pipe 8 in connection with the suction line 6. The pressure in the high temperature evaporator also acts upon a bellows 37 having a lost motion connection 42, 43, 44 with a valve 36 in a bye-pass passage 40 equalizing the pressure on both sides of the piston. On starting, valve 36 will be closed due to the high pressure in the high temperature evaporator, and the piston will be in the left-hand position due. to the spring 33. As the temperature and pressure in the low temperature evaporator 1 fall the piston moves to the right, putting the high temperature evaporator 2 into connection with the suction pipe. When the high temperature evaporator reaches a predetermined low pressure the bellows 37 opens the valve 36 by contacting the shoulder 43, thus equalizing the pressure on opposite sides of the piston, which is then forced to the left by the spring 33 to put the low temperature evaporator into connection with the suction pipe. Reduced portions on the piston allow of both evaporators being placed under suction and reduce shock. During normal working one or other of the evaporators is connected to suction in accordance with the demand, and if both require refrigeration preference is given to the high temperature evaporator. The motor is controlled by a thermostat 13 through a bellows 15 and switch 18.

Title: Improvements in or relating to governors
IPC: G05D13/00
Filed: 1942-01-09
Abstract: 577,348. Fluid-pressure servomotorcontrol systems. KALIN, A. Jan. 9, 1942, No. 369. Convention date, Dec. 30, 1940. [Class 135] In an engine overspeed governor of the type in which a normally open valve is closed on attainment of the overspeed condition to divert hydraulic pressure fluid to a pressure responsive device adapted to shut down the engine, the valve comprises telescoping sleeve members, one of which is connected to a continuously rotating part of the engine and the other is held against rotation. A shaft 10, Fig. 1, rotated in accordance with engine speed, carries the driving member 22 of a gear pump which delivers liquid from a chamber 20 to a bore 25 communicating with a duct D and through ports 27 with the interior of the shaft 10. Normally, the liquid passes through ports 30 in the shaft and a larger number of ports 31 in a sleeve valve 32 to a chamber 6, from which it returns through the hollow spindle 95, Fig. 3A, of the pump gearwheel 22a to the chamber 20. The valve 32 is normally held down and always prevented from rotation by a spring 33, but is raised by a governor 38 when the engine speed becomes excessive so that the ports 31 are moved out of register with the ports 30. Pressure then builds up in the duct D and actuates pistons P to disconnect the drive to the injector pump and so stop the engine, excess pressure being relieved by a spring-controlled valve disposed in a passage in communication with the chamber 6. A chamber 47, filled with liquid through ports 50 in the valve and passages in a plug 29 when the valve 32 is down, enlarges and draws in more liquid through a non-return valve 51 as the valve 32 rises, thus preventing return of the latter when the engine speed drops until the valve 51 is unseated, which may be effected by a manually-operated plunger 60 acting on a member 55 projecting through a nut 80. If the valve 32 is to return automatically when permitted by the governor, the nut 80 is replaced by an unperforated nut 81 which causes the member 55 to hold the valve 51 permanently off its seat. The nut not in use is attached to a stud 82 on the underside of a plate 35, which must be removed together with the valve 32 when it is desired to change the mode of operation. The lift of the valve 32 is limited by an adjustable sleeve 65, and the force of the spring 33 adjusted by a sleeve 34, the relative adjustments being preserved by a sealing wire passed through apertures in setscrews 73, 74. The chamber 6 is filled with liquid, the excess liquid passing through an overflow tube 88 and passages 90 ... 93 to a recess 21 draining into the oil reservoir or sump of the engine.

Title: Regeneration of telegraph signals
IPC: H04L25/04
Filed: 1944-01-10
Abstract: 584,374. Telegraph signal regenerators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 10, 1944, No. 473. Convention date, Jan. 11, 1943. [Class 40 (iii)] Signals are regenerated free from " splits " and " fills " and " bias " changes by producing signals having " bias'" changes only which are combined with locally generated pulses of baud frequency to produce the regenerated signals. In Fig. 1 signals from the line 1, 2 are fed through valve 3 to two similar 'but alternately operating channels, elements in one channel being distinguished from those in the other by suffixes a on the reference numerals. Mark signals of negative polarity render valve 7 in one channel non-conducting and the corresponding valve 7a in the other channel conducting. Condenser 17 charges through diode 14 when valve 7 is non-conducting and a gas-discharge valve 12 is rendered conducting with a delay of about half a baud as the condenser charges. The condenser is fully discharged by applying a pulse via 15, 16, 19 togas-discharge valve 18 to render it conducting. Opening of valve 12 renders valve 12a non- conducting by commutation through condenser 20 as described in Specification 539,254. The second signal appears in the output of valves 12, 12a and is applied to render one of valves 25, 25a just conducting and the other blocked in accordance as a mark or a space is present. The valve which is just conducting is fully opened by the next pulse from the local generator 24 producing baud frequency pulses, and permits condenser 30 or 30a to discharge so tilting the multi-vibrator 28, 28a to the appropritate condition to actuate relay 38 for producing the regenerated signals.

Title: Method for the production of rapid growing hybrid trees and their propagation
IPC: A01H1/02
Filed: 1936-01-09
Abstract: A process for the production and propagation of rapid-growing hybrid trees, of the poplar or other families, to provide raw material for the paper-making and other industries, consists in artificially pollinating female flowers with pollen from male flowers of another tree of the same family but different species, growing seedlings from the resulting seeds, selecting the seedlings which possess the largest amounts of root-producing hormones and show at least 50 per cent increased dimensions and 15 per cent increased fibre length as compared with the parent trees at the same age, taking cuttings or prunings from the selected seedlings, saturating them with moisture, and raising trees from them by sexless propagation.  The seedlings may be grown in poor mineralized soil.  Green or other cuttings taken from the seedlings or the resulting trees may be dried after being saturated with moisture and their upper parts may be coated with a wax, paraffin, or other waterproofing material having a minimum melting-point of 50 DEG  C.  A water-proofing material may be applied as a solution in a solvent.  When planting the cuttings the lower part, amounting to 2/3 to 4/5 of the cutting, is inserted in the soil.  A dilute suspension of Bordeaux mixture or other disinfectant may be used instead of water for saturating the cuttings.  A list of the different species of trees which may be paired to produce the hybrids is given in the Specification. U.S.A. Specification 1,943,030 is referred to.
