Title: Improvements in or connected with knitting machines
IPC: D04B35/02
Filed: 1921-06-23
Abstract: 186,405. Scott, R. W. June 23, 1921. Circular machines; needles.-Cylinder or dial needles for a plain knitting-machine or the primary or secondary needles, or both, of a rib machine are made composite, one element A being provided with a loop-drawing hook 10 to take the new loop z, while the other part B is preferably in the form of a slide which is provided with a return bend hook 12 adapted on retraction by cams C acting on the butt b to enter and engage a previous loop y on the hook 10 and cast it off over the new loop. The point of the hook 12 is received when retracted in a groove 11 in a raised part of the element A and a thinned tail piece B<1> of the part B fits slidingly in an open groove e in the side of the rear part of the element A. The tail piece B<1> is slightly bent sideways to form a spring which acts frictionally on the side walls of the containing groove of the dial. The hook 12 may be provided with an outwardly projecting point 13, Fig. 10, to engage loops of the fabric at a desired time, so that the projection of the part B may carry the loops to a position where the rising cylinder needles P<1> can enter and engage desired loops for transfer purposes as described in Specification 11481/06. Fig. 12 shows knitting cams 23, 24, and 25, and Fig. 13 shows transfer cams 26, 27 for this purpose. Both sets of cams are independently insertible and withdrawable, and are mounted and actuated in the same manner as the cams a, b, c described in Specification 102,711. The parts B may be bevelled at 14 to deflect any rising cylinder needles P<1> that should happen to strike the parts B when projected. The central outer ends p of the hooks of the cylinder needles, when of the latch-needle type, may be made somewhat pointed to enable them to pierce the fabric loops more easily.

Title: Improvements in or relating to vermin traps
IPC: A01M23/20
Filed: 1954-06-14
Abstract: 765,077. Vermin traps. BARKER, C. May 25, 1955 [June 14, 1954]. No. 17428/54. Class 5(1). A vermin trap of box or cage form comprises a false floor adapted to be depressed by vermin in the trap so as to complete a circuit including an electrical severing device operative on means holding the door or doors of the trap open. In the set position, the doors M of the trap are held open by means of a thread C passing over a resistance wire held in position across a slot P in plates T mounted on top of the trap. When the false floor L of the trap is depressed by the weight of the vermin in the trap, the switch H is closed and the circuit containing the resistance wire is completed, whereupon the wire becomes hot and burns through the thread C, with the result that the doors close. Cross wires D are mounted by means of loops at their ends on vertical side members N of the door openings and, when the doors close, drop down on the outside of the doors to lock them in position. As the doors come into their closed position, the striking plate E mounted on one of the doors strikes the operating pin of a switch F to open the circuit. As described in the Provisional Specification, the doors of the trap are hinged at their lower edges, the threads C being attached to their upper edges and passing over pulleys to a suspended weight in such a manner that on severance of the suspension wire by an electromagnetic severing device, the weight falls and the threads leading to the doors are tensioned suddenly, pulling the doors into their closed positions. As before, the severing device operates on the completion of an electric circuit by the depression of a false floor in the trap,

Title: Improvements in or relating to the hydrolysis of fats
IPC: C11C1/04
Filed: 1940-12-11
Abstract: 547,401. Splitting fats. STRODE, M. (Colgate-Palmolive-Peet Co.). Dec. 11, 1940, No. 17557. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 30, 1941.] [Class 91] In the aqueous saponification of. fats under heat and pressure with counter-current flow between the fats and water, the fats are preliminarily heated in contact with water or glycerine-water, preferably with glycerinewater resulting from the hydrolysis, to the desired hydrolysis temperature under a pressure sufficient to keep the water liquid. This temperature is above about 185‹ C. and may be 240‹ C. at which latter temperature further heating for the hydrolysis may be unnecessary. The fats absorb some of the water required for their hydrolysis, the excess of the countercurrent flowing water being available for washing the liberated fatty acids leaving the upper part of the reaction column; if glycerinewater is used in the preliminary heating, the glycerine is incidentally concentrated. The hydrolysis is effected in a usual type of reaction column 15, such as that described in U.S.A. Specification 2,139,589, with or without trays, water being admitted at the top and the fats through an inlet 20 at the bottom ; the fatty acids are withdrawn at the top and glycerine-water through an outlet 17 at the bottom. The preliminary heating of the fat and glycerine-water mixture is effected in a heat exchanger 22, the fresh fat being injected by a pump 21 into the stream of glycerine-. water circulated from the pipe 17 through the coil 19 of the heat exchanger to the inlet 20 back to the reaction column. Some of the glycerinewater falls into a separator 23 from which it is withdrawn at a rate sufficient to keep the interface between the fatty matter and glycerinewater in the column at the desired position. Part of the withdrawn glycerine-water may be used as the heating fluid of a heat exchanger used in series with the heat exchanger 22. The location of the separator 23 in the circuit may be varied, and provision is made for the admission of fresh water. In another modification of the plant, the mixture is preheated by passing it through a coil immersed in the liquid in the separator before admitting it to the heat exchanger. The fresh fat may be directly injected into the separator, no heat exchanger being used, and the aqueous phase in the column being separately heated by a heating coil. In a further modification, the hot mixture of fat and glycerine-water is returned to the column through nozzles located in the lower part of the fatty phase. The fatty acids may be collected in a vessel arranged above the column to which the water for the countercurrent flow is directly admitted. The latter with admixed fatty acids is then preliminarily heated in a heat exchanger before admission to the top of the column, preferably through nozzles arranged within the upper part of the latter.

Title: Plastic covers for piping
IPC: F16L58/18
Filed: 1972-04-17
Abstract: 1429173 Pipe-joint coverings BP CHEMICALS INTERNATIONAL Ltd 11 May 1973 [17 April 1972 (2) 13 Oct 1972] 17564/72 47281/72 and 47282/72 Divided out of 1429173 Heading F2G In laying welded sections of weight coated steel piping under water, the weld 3 is enclosed by a plastics sleeve 6 into which a settable filler material 14 is introduced in a flowable condition. On setting, this forms a locking engagement with part (e.g. 18, 19) of the sleeve. The sleeve may be made of high density polythene, which may be foamed or of a copolymer of alkenes. The filler material consists of an extending filler such as aggregate and a binder, which may be hydraulic cement, unsaturated polyester resin or epoxy resin. After introducing the aggregate by a screw-fed mechanism, so that it travels helically around the pipes, guided by the ribs 11, suction is applied at 12 to saturate the aggregate with binder. The unsaturated polyester binder is rapidly cured in the presence of curing catalysts and promoters and an unsaturated monomer, with which it copolymerizes. The binder is made by esterifying saturated dihydric alcohols or bisphenol A adducts with α unsaturated, α,# dicarboxylic acids. The polyester can be modified by replacing some of the unsaturated dibasic acids with saturated dibasic carboxylic acids.

Abstract: 698,407. Refrigerating ; heat-exchangers. GODFREY ASSETS, Ltd., [formerly GODFREY & PARTNERS, Ltd., Sir G.], and JAMIESON, A. W. H. Oct. 4, 1950 [July 4, 1949], No. 17626/49. Classes 29 and 64 (iii) [Also in Group XXIX] Air conditioning means for an aircraft cabin or space 1 comprises a vortex tube 7 as described in Specification 405,781 supplied with compressed air from the compressor unit 3 of the main gas turbine or from a separately driven air compressor or a forwardly facing air inlet passage, the air passing first through a heat exchanger comprising an annular passage 5 surrounding the vortex tube and entering the vortex tube by a tangential nozzle 8 adjacent a diaphragm 9 with a central aperture 10 through which the cold air passes to the cabin 1. The hot air from the vortex passes through a restricted opening 11 forming an ejector nozzle which induces a draught of cooling air through an outer annulus 6 surrounding the passage 5 to cool the compressed air before it enters the vortex tube. This cooling air is admitted direct from the atmosphere by a duct 4 and mixes with the hot air in a pipe 12. The heat exchanger passages 5, 6, are provided with corrugated plates. To control the cooling the flow of hot air through the restricted orifice 11 is adjusted by a valve 14 carried by a bellows 15 to which the compressed air is admitted through an aperture 17 and from which the air escapes by an aperture 18 and pipe 19 leading to the cabin. The outlet 20 of pipe 19 is controlled by a valve 22 on a bimetallic element 21 so that the valve 14 is moved in accordance with the temperature in the cabin. To adjust the thermostat the bimetallic element is movable relatively to the outlet 20 by a screw 23. Hot air may be led to the cabin from the outlet 11 of the vortex tube, and may also be thermostatically controlled. The cold air may be used to cool radar or other apparatus or for making ice, and the hot air for cooking.

Title: Means for the interconversion of reciprocatory and rotary motion
IPC: F16H21/28
Filed: 1944-05-18
Abstract: 581,575. Interconversion of rotary and reciprocating motion. SANDERS, A. F., and MORGAN, W. May 18,1944, No. 17651/43. [Class 80 (iii)] Mechanism for the interconversion of motion between reciprocable and rotatable members having mutually perpendicular axes, comprises a connecting rod 24, Fig. 1, pivoted at 25 to the reciprocating member and having sliding engagement at 23, 23, with intersecting transverse guideways A, B, in the rotatable member 20, the connecting rod 25 also having a pin-andslot or like connection 26 with an auxiliary shaft (not shown) the axis of which is parallel to the axis of the rotatable member 20. Thus one revolution of the member 20 produces four strokes of the reciprocating member and two revolutions of the auxiliary shaft. The connecting rod may have a third pin 28 slidable in a guideway C, Fig. 4, bisecting the guideways A, B. In this case the pins 23, 28, are equidistant from the centre point of the line joining the two pins 23 and the pin 25 must be capable of lateral movement. The pin 28 may be on the side of the line 23, 23 remote from the pin 25 or pins 28 may be arranged on each side of the said line. The guideways may not be rectilinear or at right angles to one another and need not pass through the axis of the rotatable member 20. The axis of the reciprocable member also may be offset from the axis of the member 20. Thus if the mechanism is embodied in an internal-combustion engine periodic variations occur in the stroke length or mean piston speed, e.g., the suction stroke may be of longer length than the working stroke. If the pin 26 for the auxiliary shaft is midway between the two pins 23 it may have a crank connection with the auxiliary shaft. In a modification, the pins 23, 23, 25, 26 are all in line.

Title: Method of Controlling and Apparatus for Producing Electric Arcs.
IPC: H05B31/00
Filed: 1916-12-14
Abstract: 110,982. Comstock, D. F., and Technicolor Motion Picture Corporation. Dec. 14, 1916. Arc lamps.-An arc, particularly a heavy-current arc employed in a projection lamp, is rendered steady by a magnetic field which is slightly inclined to the arc path. This inclination may be in a plane containing or parallel to the electrodes, in a plane at right-angles to this plane, or in both planes. The electrodes may be offset relatively to each other. The arc takes the form of a helix, making a fraction of a turn or one or more turns. In one arrangement, the poles N, S, Fig. 1, of a magnet 5, 6, 7 surround the negative and positive electrodes 1, 2 respectively, which are off-set as shown in Fig. 2. The field is such that lines of force traversing the centre of the tip of the negative electrode pass through the end of the positive electrode near its upper edge. A winding C exciting the magnet is connected either in series with the arc or in shunt therewith through a rheostat r. In order that a thin negative electrode 1 may be used, connexion is made with it by a graphite sleeve 11 having a flange which is gripped by rings 15, 16 screwing together. One ring 16 has a binding screw, and the other is attached to the magnet pole by an insulated pin 17. Refractory sheaths 3, 4 surround the positive electrode and the sleeve 11 of the negative electrode. Fig. 5 shows one magnet pole S displaced both vertically and horizontally with regard to the positive electrode 2, and the other pole N displaced at right-angles to the plane of the electrodes, to produce an oblique field. A similar result can be attained by the use of narrower alined cylindrical poles not surrounding the electrodes. Fig. 8 is an elevation of an arrangement having the electrodes both horizontal but relativelv displaced both horizontally and vertically. The pole S around the positive electrode 2 is enlarged upwards and also horizontally in the same direction as the negative electrode 1, while the other pole N is enlarged in the opposite directions to the first pole. An oblique illuminating area is thus maintained on the positive electrode. Specification 101,885 is referred to.
