Title: Improvements in knitting machinery
IPC: D04B9/26
Filed: 1939-02-07
Abstract: 525,540. Knitting machines. SCOTT & WILLIAMS, Inc. Feb. 7, 1939, No. 10733/40. Convention date, Aug. 30, 1938. Divided out of 528,566. [Class 74 (ii)] To enable striping in the leg and instep and tipping in the heel and toe of a stocking to be. produced,. a circular machine is provided with means by which yarn changes are effected upon. substantially the same group of needles during. rotary and reciprocatory knitting. The invention is described in connection with a superposed cylinder machine having yarn changing. means as described in Specification 301,350, [Class 74 (ii)], in which yarn fingers 6 are acted upon by levers 8 engaging cams 16 intermittentlyrotated by pawls 20 under control of a link 28. The link 28 is secured to a crank pin 202 and means are provided for advancing or retarding the crank pin 202 approximately 50 degrees: with respect to the shaft 106 by which it is rotated. The shaft 106 has secured to it a collar member 190 having a radial projection 192 and two axially extending pins 194, 196 and loosely mounted upon the shaft is a second collar -198 carrying the crank pin 202 and a spring pressed pawl 204 for engaging the projection 192. A bell-crank lever 214 engages cams 228, 230, 232 and has cam members. 218, 220 to engage the end 210 of the pawl 204 during rotation of the shaft 106. Engagement of the lever 214 with a high cam 228, e.g., when commencing the knitting of the heel, causes the cam 218 to engage the pawl 204 when the crank pin is at its lower dead centre, so that when the projection 192 is released, a spring 30 advances the crank pin faster than the shaft 106 and the pawl, previously in the position shown. in Fig. 6, snaps in front of the projection 192, .and the collar 198 and crank pin are driven by 'the projection 192. Cam 230 holds the lever 214 so that both cams 218, 220 are inoperative. The low cam 232 is brought into operation when rotary knitting is restarted, and the cam 220 acts upon the pawl 204 when the crank pin 202 is at top dead centre, and the spring 30 serves to retard the crank pin with respect to the shaft 106 so that the pawl snaps behind the projection, and the collar 198 and crank pin are driven by the pin 196.

Title: Improvements in or relating to means for propelling vehicles, particularly aircraft
IPC: B64C29/00
Filed: 1935-04-08
Abstract: 431,512. Rotary pumps. STENNING, G. A., 119, Park Road, Worthing, Sussex. April 8, 1935, No. 10789. [Class 110 (ii)] The pump, designed for aircraft propulsion, comprises two parallel rotors 1, 2, each having flexible vanes 7 attached to rods 6 on the peripheries of the rotors. The rotor shafts are driven and centrifugal force causes the vanes to fly outwards and impel air from an inlet 4 to an outlet 5. The vanes may be made of silk, leather, or thin steel, and may be hinged to the rods 6. The air is delivered against surfaces on the aircraft. A number of pumps may be used, inclined at various angles, or arranged parallel.

Title: Method of increasing the output of sintering apparatus
IPC: C22B1/20
Filed: 1956-04-09
Abstract: Finely divided ore mixed with solid fuel and, if required, sinter returns and moistened is thoroughly mixed, e.g. in a mixing drum and then granulated by rolling e.g. in a granulating disc or drum before charging on to a sintering band.  Pellets of less than 15 m.m. and preferably 2-10 m.m. diameter are formed but need not be of uniform size.  The pellets are preferably charged on to the sinter band after as short a storage time as possible by controlling the rate of charging the granulating apparatus in dependence on the speed of travel of the sintering band.

Title: Improvements in apparatus for extracting weeds, roots or the like from the ground
IPC: A01B1/18
Filed: 1935-04-09
Abstract: 449,583. Hand tool for extracting weeds &c. HUMPHREY, H. A., 60, Frant Road, Tunbridge Wells, Kent. April 9, 1935, No. 11011. Addition to 412,407. [Class 6 (ii)] Apparatus for extracting weeds, roots, &c. from the ground of the kind described in the parent Specification and having the cutting - members carried on arms which are so pivoted that the distance of the pivot or pivots above ground level when the cutting-members are buried in the earth is greater than the effective length of the cutting - members, comprises a pivoted lever operating a cam or cams or an equivalent device so constructed that by moving the lever first in one direction and then in the opposite direction the cutters are first opened out by a smooth action and the weed previously extracted is ejected and then the ejectors are withdrawn and the cutters are left at any desired distance apart ready for the extraction of another weed, the arrangement being such that the lever automatically follows up the closing movement of the cutters, which occurs substantially along the path of least resistance when they are pushed into the ground, and enables the cam to prevent the cutters from separating at all positions taken up by them during their closing movement. The cutters 1, 2 are shown carried by wooden arms 3, 4 connected by a hinge 5 at their upper ends and provided with handles 6, 7. A hand-lever 11 is pivoted on a bracket 9 on one arm 4 and carries rollers 13, 14 engaging a curved cam 8 on the other arm 3. Ejectors 19, 20 are carried by arms 17, 18 pushed apart by a spring 21 and hinged on the lever 11 which is connected to the hinge 5 by a spring 24. Rubber buffers 22, 23 limit the movements of the lever 11. In a modification, a spring presses the arms 3, 4 apart and the lever 11 is pivoted on a bracket on the arm 3 and carries a cam engaging the arm 4. Instead of a cam the lever 11 may be provided with an arm carrying a roller. In another modification, the arms 3, 4 are cast and the lever 11 works in a slot in one of the castings. The cam may consist of a slotted metal plate engaged by a stud on the lever. The apparatus may also be made of sheet metal stampings bent and riveted together. The cutters may be made of rustless steel sheet. Where there is a central member linked to the two vertical arms the lever may be attached to it and may operate a cam for each arm.

Title: Improvements in water demineralizing apparatus
IPC: C02F1/08
Filed: 1962-03-26
Abstract: 972,150. Distilling water. GENERAL ELECTRIC CO. March 26, 1962 [March 28, 1961], No. 11407/62. Heading B1B. Water is distilled under non-boiling conditions uy warming it and passing the warm water into the sump 56 of chamber 46 where the water is distributed, in the form of a film, on the surfaces of discs 62, 63, 64 which rotate slowly, e.g. at 5-50 revolutions per minute, the upper parts of the discs moving close to the cool surfaces of heat-exchangers 47, 49 and 51. Air is present in the space between the discs and the cool surfaces. Water evaporates from the films on the upper parts of the discs, and the vapour diffuses through the air to the cool surfaces where it condenses, the condensate flowing down to trough 67, and being 'collected in tank 75. The distance between the discs and the cooling surfaces may be about 0À3 cm. The water to be distilled, supplied through line 45, is passed through heat-exchangers 47, 49 and 51, where it acts as cooling medium and is itself progressively heated. The water next passes through heater 54, and is then introduced into sump 56, which is divided into three sections by partitions 58, 59 having openings 60, 61 respectively. The distillation may be carried out at a temperature of about 80 C. The pressure in the chamber 46 may be maintained at about 3À5 atm. by means of an air-pump 81. Alternatively, the pump may be used as a purge for removing non-condensible gases and permitting the apparatus to operate at a steam pressure slightly less than the pressure of the raw water in line 45. Residual water is withdrawn from the sump through line 68, and part of it may be recycled, if desired, to line 45. A modified apparatus is also described wherein there is disposed in the sump a heating-coil which is connected via a compressor with the cooling heat-exchangers so as to operate as a refrigeration-circuit.
