Title: A machine for stripping the insulation from the ends of insulated electric conductors
IPC: H02G1/12
Filed: 1946-02-27
Abstract: 609,834. Stripping cables and conductors. SPORING, P. A., JOHNSON, C. P., and TELEGRAPH CONDENSER CO., Ltd. Feb. 27, 1946, No. 6102. [Class 36] In a machine for stripping insulation from the end of an electric conductor, the operation of a pair of jaws to grip, or release, the conductor, and of mechanism for sever. ing the insulation at a predetermined distance from the end of the con. ductor, as well as movement of the jaws to uncover the bared portion of the conductor, are effected by the movement in one direction of a single actuating - member. As shown, the end of the cable &c. 10 is fed up to an adjustable stop 22 between the (normally) open jaws 9 which are formed on levers 8, pivoted on a slide 2 and have exten. sions 11 normally constrained by springs 12 to hold the jaws open. Adjustable pins 21, carried by the arms 11 are arranged in the path of a knife-edge 20 on a pivoted lever 14 which is rocked to separate the pins 21 (and merely close the jaws 9) through linkage 17, 19 and a treadle or the like. The severing mechanism comprises a fixed cutter 23 and a movable cutter 24 carried by an arm 28 which is normally held in its raised position by means of a spring 31. The cutter 24 is lowered on to the cable by the engagement of the upper end 36 of the lever 14 with a roller 35 on an extension 34 of the arm 28. In the further movement of the lever 14, blocks 37 on the lever abut the pins 21, whereby the slide 2, with the jaws 9, and the gripped portion of the cable, are moved until the pins 21 enter pockets 39 on the lever 14. The pull of the springs 12 then releases the grip of the jaws 9 so that the cable may be withdrawn, the severed portion of insulation being withheld by the cutters. On release of the treadle, the lever 14, slide 2, jaws 9, and cutter 24 are returned to their starting positions by the springs 40, 4, 12 and 31 respectively.

Title: Improvements in small synchronous electric motors of the permanently-magnetised rotor type
Inventor: CLIFFORD CECIL FRANK
IPC: H02K21/14
Filed: 1951-03-14
Abstract: 698,565. A.C. motors. HORSTMANN GEAR CO., Ltd. March 7, 1952 [March 14, 1951],No. 6127/51. Class 35. In order to produce a rest position favourable for restarting the permanently magnetized rotor of a synchronous clock motor is so constructed that the rest position of minimum reluctance between rotor and stator poles is different from the position produced by energizing the stator poles; usually this position is such that the axes of the rotor poles are opposite gaps between the stator poles. In one form, Fig. 3, this is done by bifurcating the rotor poles 8, 9 which are equal to a stator pole-pitch, by notches 10 of a size equal to a stator polewidth. Energization of the stator poles tends to move the rotor into a position such as B, in which the polar axes x are opposite stator poles, the reluctance being greater because of the notches 10. The notches may be replaced by unmagnetized portions of the pole-faces. In a modification, Fig. 4, having an even, instead of odd number of stator pole-pairs, the same result is achieved without using notches by relative displacement of the poles at either end of the rotor combined with the unsymmetrical cutting away of the poles at 13. Thus the centre-lines x of the poles 11 correspond in position to centre-lines y of poles 12, but are actually constructed so as to be off-set by about half a stator tooth pitch as shown in solid lines. Owing to this off-set and the cut-away parts 13, energization of the stator teeth tends to move the rotor into a position such as B, where the approximation of poles of opposite polarity is greater but the reluctance is also greater.

Title: Apparatus for processing a solution by reverse osmosis
Inventor: BARNABE JEAN-LOUIS
IPC: C02F1/44
Filed: 1967-02-09
Abstract: 1,121,336. Reverse osmosis. SOC. DE RECHERCHES TECHNIQUES ET INDUSTRIELLES. 9 Feb., 1967 [15 Feb., 1966], No. 6300/67. Heading B1X. A solution, for example sea-water, is subjected to reverse osmosis in apparatus comprising vessel 1 which may be filled with the solution through opening 59, means for example piston 13 moving in guide tube 5 for applying pressure to the solution, flexible bag 38 which is filled with gas and is compressed on application of pressure to the solution, a plurality of semi-permeable membrane assemblies 41 which may be mounted on tube 5, and means for removing from the vessel solvent which has passed through the semi-permeable membranes. The membrane assemblies may comprise pairs of cellulose acetate membranes (42), (43) mounted on porous nickel supports (44), (45) with an intermediate space (46) in which solvent collects (Fig. 2 not shown). The solvent drains downwardly in grooves 51 machined in the outer wall of tube 5, and out of the apparatus at 54. In the embodiment shown, on operation of piston 13, on the downward stroke solution from reservoir 32 flows into the annular space 16 between piston rod 12 and tube 5 and solution from space 17 is forced through valve 23 and duct 20 into the vessel. On the upward stroke, the solution from space 16 flows through duct 15 into space 17. When the pressure in the vessel is high enough the reverse osmosis process begins. In an alternative embodiment (Fig. 4 not shown) a cartridge (62) containing for example calcium hydride (63) and surrounded by frangible matrix (64) may be inserted into space 17 and is broken by the piston. The gas which is generated serves to increase the pressure in the vessel. There is reference to cooling the vessel during the compression stage and warming it to increase the gas pressure during the reverse osmosis stage.

Title: Improvements in or relating to the manufacture of cellulose or cellulosic compounds
IPC: D21C3/22
Filed: 1930-11-08
Abstract: 371,037. Cellulose. DREYFUS, H., 22, Hanover Square, London. Nov. 8, 1930, No. 6306/32. Divided on 371,000. [Class 96.] In a process for producing cellulose or cellulosic materials by treating wood, straw, grasses and the like with hot alkaline liquors under pressure, the treatment is effected in the presence of one or more volatile aliphatic alcohols, which exert a pressure in the digester. Additional pressure may be produced by other means, e.g. by pumping inert gases or vapours into the digester, or by their development from materials introduced into the digester for that purpose. The pressures employed are higher than usual, e.g. 20-100 atmospheres, and the temperature is preferably 100-120‹ C. The alkali is preferably used in excess, e.g. 20-50 per cent excess of the theoretical quantity, and preferably in dilute solution, e.g. 2-4 per cent. In an example 100 parts of wood chips is subjected to vacuum and impregnated with 900-1200 parts of 4 per cent caustic soda. 10-35 parts ethyl or methyl alcohol is added, the digester closed, and nitrogen pumped in until the pressure is 20-25 atmospheres. After 1-2 hours the temperature is raised to 100- 120‹ C. and maintained at that temperature for 3-7 hours.

Filed: 1940-04-08
Abstract: 540,327. Grilling stoves. RAMSEY, A. R. J. (Connerton Appliance Co.). April 8, 1940, No. 6312. [Class 126] A grilling oven in which a grill plate 20 is normally positioned beneath fixed burners 22, is provided with a second burner 100 arranged beneath the grill plate and movable therewith into and out of the oven. The plate 20 is secured to a pair of legs 78 pivoted at spaced points 78a, 78b to members 76, 82 pivoted at 72 and 84 to a bracket 70 slidable on guide bars 64 in the oven. A pawl 90 pivoted to a crosspiece 86 connecting the legs 78 engages one of a series of teeth 92 in a web connecting the brackets 70 to hold the grill plate in any of a number of positions. The pawl 90 may be released by a push rod 94 passing through a front plate 24 fixed to the grill plate and provided with a handle 96. The distance between the pivots 78a, 78b is slightly different from that between the pivots 72 and 84 so that the grill plate when raised to grilling position is slightly tilted rearwardly so that fat can drain therefrom. Fuel is supplied to the burner 100 from a heater 104 connected by a flexible pipe 108 to a supply chamber 60 which also supplies the burners 22 through a header 55. Between the grill plate 20 and the burners 22 is a grid 26 which may be lowered on to the meat on the grill plate to give the cooked meat a scored appearance. This grid is supported by end pins 32, Fig. 3, in arms 34 pivoted on pins 35 and connected by links 37 to pivoted arms 38 one of which is connected to a mounting lever 42 having teeth 44 for engagement with the lower edge of a slot 45 in the front of the oven. By releasing the lever 42 and pulling it forwardly by means of its handle 43 the grid is lowered on to the meat, pin and slot connections 37<SP>1</SP>, 38<SP>1</SP> between the links 37 and arms 38 permitting the. grid to adjust itself to the inclination of the grill plate. A front plate 50 provided with windows is carried by one end of levers 46 and slightly overbalances weights 48 on the other end of the levers. When the grid 26 is raised, the plate 50 is lifted by the engagement of fingers 36 on the arms 34 with the levers 46. The top plate 12 of the oven may be used also for cooking purposes, the fat draining into grooves 1188 at the front and sides and passing thence through a drain 118a, 120.

Abstract: 265,796. Witt, W. J. de. March 8, 1926. Moulding celluloid and other sheet material.- A removable hollow shoe form, filler, or last for temporary insertion in a finished or partly finished shoe consisting of thin, light, resilient non-absorbent material such as celluloid, shaped to conform with substantial exactitude to the solid last on which a shoe is made, is formed from a blank such as 6, Fig. 6, cut or punched from sheet, or moulded or sliced from a block, and conformed to a last by hand or preferably by pressure of a solid last 19, Fig. 7, upon the blank laid on a steam-heated bag or cushion 1. The bag has upper and lower walls, the upper one pervious to steam and is mounted on an inclined support, 7<a>, Fig. 17, forming a false bottom to a box 7b. The upper and lower walls of the bag are preferably united by a seam 10, Fig. 7. Steam is admitted by a pipe 12. The seam 10 assists in forming two lobes 14. 15, Fig. 9, to the bag 1 when inflated. A table 7<c>, Fig. 17, is provided with a treadle 22 and locking pawl 23 for holding a solid last 19 mounted on a rocking spindle 18 in contact with the bag in line with the seam 10. The heat of the bag and the moisture soften the blank which is thrust down into the bag when the treadle 22 is depressed and locked down by a stop 24. Corners 5, 6, Fig. 7, of the blank are turned over the last and tacked down. Projecting edges of the blank form flanges 28, 29, Fig. 3, and wrinkles 30<a> tend to form at the toe. The treadle 22 is then released and the last 19 with the blank may be thrust into a cylindrical cushion 44, Fig. 14, inflated with air to smooth and conform the blank to the last round the top meantime cooling the blank. In addition, or alternatively, the blank and last may be thrust between a pair of pneumatic cushions 47, 48, Fig. 10, mounted in a box support to draw flange portions of the blank inwardly. The fillers are provided with indicia obtained by pressing the last with the filler thereon upon a cushion surface 58, Fig. 18, of a tilting table 56 pivoted at 57 to a base. The table is tilted downwardly until the toe of the last is brought into engagement with a resilient pressure roll or pad 59, which may be heated by a steam jet 59<a>. The pad causes the filler material to sink into incised indicia 54, Fig. 19, in the toe of the last. Alternatively, the fillers may be pressed into the bag, Fig. 17, which may have an internal pad to press the filler toe into the indicia on the last. To ensure exactness in size it is preferable to heat or dry the solid last to reduce its size and then to fill the pores of the last with moisture resistant medium; alternatively, the solid last could be made of moisure resisting material and undersize.
