Title: Flat-bed knitting machines
IPC: D04B7/04
Filed: 1963-10-01
Abstract: Fashioning mechanism is provided on a flatbed machine and comprises a group of eyed points 13 Figs. 16 and 17 (not shown) which are adapted to be pivoted into a position in which they engage over the hooks of the needles.  The points are mounted in a bar 11 on a support 10 which also carries sinker elements 17 such that when the points are positioned to engage the needles, the sinker elements are positioned to project between the needles. The points thereupon are withdrawn drawing the engaged needles outwardly such that the sinker elements engage the fabric loops and cause the needle loops to slide downwardly below the needle latches.  The points are then projected forwardly and engage under the needle loops whereupon the support 10 is pivoted upwardly to raise the points and sinker elements clear of the needles.  The support is now shifted along the needle bed to align the points with the adjacent needles in which position the points are lowered together with the sinker elements so that the needles to which the loops are to be transferred are now engaged by the points.  The points are withdrawn again drawing the corresponding needles outwardly so that the loops are transferred to them and the needles then pushed back into the needle bed.  The points and similar elements are then raised to an inoperative position.  The support 10 is controlled by shafts 7 and 8 which are rotated and moved horizontally to impose the necessary movements of the support.  The shafts are controlled through gearing by cams on a cam shaft.

Title: Fluid mixing apparatus
IPC: B01F7/00
Filed: 1958-12-01
Abstract: 840,078. Mixing fluids. TECHNICON INSTRUMENTS CORPORATION. Dec. 1, 1958 [Jan. 15, 1958], No. 38717/58. Class 86 Apparatus for mixing two or more fluids, at least one being viscous, comprises a chamber 18 enclosing a high speed rotary multi-armed impeller 34, the clearances between the stationary and rotating parts being small whereby a small quantity of one liquid fed by the line 11b<SP>1</SP> and passage 43 to the chamber 18 is separated and swept to another entry point for another liquid supplied by the line 11a<SP>1</SP>, the liquids being thus mixed initially in small fractional quantities. The mixing is intensified by the pumping pressure in the lines 11a<SP>1</SP>, 11b<SP>1</SP> overcoming the centrifugal tendency of the rotating liquid mass, by forcing it inwards towards a central discharge passage 28, turbulence being thus produced. Further turbulence is induced by the action of the hub of the arms of the impeller, the hub being of square section and being arranged partially to obturate the passage 28, the restricted paths into the passage 28 being rapidly changed in position as the impeller rotates. The mixed liquids pass into a chamber for discharge through fitting 56. If the demand for the mixture is less than the supply from the pump, the excess is discharged at 62. The impeller is driven by a motor 40 and the shaft 38 is supported on a ball footstep bearing 19. The pump 11 may be of the type described in Specification 817,070, consisting of a number of flexible tubes 11a, 11b which are pressed against a platen 11c by rollers 11d on a chain conveyer.

Title: Improvements in methods of and apparatus for activating aluminium and producing organic derivatives therefrom
IPC: C07F5/06
Filed: 1958-12-02
Abstract: Aluminium to be used in the preparation of organo-aluminium compounds is activated by reaction with one or more halogens, halogen hydrides or organic substances containing labile halogen atoms, and the resulting aluminium halide separated from the aluminium.  Chlorine and hydrochloric acid are the preferred reagents and when using these the aluminium trichloride formed can be easily volatilized: tetrachlorethane and tetrabromethane may also be used.  The rate of the activation reaction may be controlled by diluting the activator with an inert gas such as nitrogen, argon, propane or butane, or by lowering the pressure at which the reaction <FORM:0901166/IV (b)/1> is conducted.  The activation and conversion of the activated aluminium into say, alkyl aluminium compounds may be conducted in the apparatus shown.  Aluminium shot is stored in a hopper 1, the lower part 2 of which is cylindrical and surrounded by a furnace 5.  The part 2 is provided with an inlet 6 for an inert gas, an inlet 7 for the introduction of the halogen activator and an outlet 8 for removal of aluminium halide and gases formed.  The activated aluminium passes via an air lock 4 into the reaction tower 3.  At the bottom of the tower is a perforated plate 11 on which the charge lies, liquid products 12 falling through the plate and being drawn off.  The organic substance which is to react with the activated aluminium enters at 14 and is pumped via 16 to a sprinkler 18.  An inlet 19 allows for the introduction of a gas such as hydrogen.

Title: Electrophoretic painting process
Inventor: STOODLEY KEITH HERBERT
IPC: C25D13/20
Filed: 1963-10-04
Abstract: An article is electro-phoretically painted by applying thereto an undercoat to provide a conductive layer on the article and then a further coating by electro-phoretic deposition of a paint. For non-conductive articles, e.g. of plastic or glass, the undercoat may be applied by spraying. When the article possesses a conductive outer layer e.g. of iron the undercoat is preferably deposited electro-phoretically, being a waterthinnable paint comprising a conducting pigment, such as carbon, aluminium, silver or metallized plastic or pigment, and water-dispersible resin as binder, e.g. 5 to 20% of phenolic or melamine alkyd or vinyl-modified alkyd resin.  To render the undercoat conducting, sufficient conductive pigment must be present e.g. 1 to 10%.  The water-thinnable paint may contain 5 to 20% of the water-dispersible resin and additionally an alkaline material such as NaOH, NH3 or an amine e.g. tricthylamine to give it a pH of 7.25 to 9. The undercoat may be stoved prior to the further coating; both coatings may be polymerized.

Title: Improvements in or relating to electrohydraulic forming apparatus
IPC: B21C37/08
Filed: 1965-09-15
Abstract: 1,109,147. Electrohydraulic forming. GENERAL DYNAMICS CORPORATION. 15 Sept., 1965 [21 Sept., 1964], No. 39362/65. Heading B3Q. Electrohydraulic forming, piercing and embossing apparatus comprises a pair of die-sections 34, Figs. 2 and 4, defining between them a die-cavity and movable towards and away from one another, means for creating an electrical discharge in the cavity when this is filled with a liquid, e.g. water, and means for positioning work within the cavity. The die-sections are carried in inserts 44 in holders 40 slidable, by means of upper sleeves 150 and lower rolls 168, on tie-rods 142 which extend between frames 136 of the machine. For larger dies 34, the inserts 44 may be omitted. An hydraulic pump 182 supplies cylinders 174 for moving the die-holders 40, the piston in the left-hand, Fig. 4, cylinder encountering the end of its cylinder and forming a reference position while the right-hand holder is still moving. Inner limit switches (190, 192), Fig. 3 (not shown), are tripped on closure of the holders, the switches stopping pump 182, closing valves 186 and operating high-pressure, air-operated, hydraulic pumps 184, which increase the fluid-pressure in the cylinders 174, the pressure in the left-hand cylinder being increased more than the other to preserve the reference position. Outer limit switches (194, 196) are provided for stopping the pump 182 after separation of the holders. The spark, or vaporizable-wire, electrode-head 32 with water supply duct is described in Specification 1,109,146, to which reference is made, and is raised from the die-sectors by a pneumatic cylinder 274. In its lowered position, limited by stop-screws (130), Fig. 6 (not shown), the head is locked to the die-sections by bolts (302), Fig. 8 (not shown), extended into pockets (300) in a collar (110) surrounding the head. A platform 90, supporting a plug 92 for locating the work 30, is carried by a slide 210 balanced by a counter weight 226 and movable by a handle 232 which releases a spring-lock. A flexible drain pipe 238 is connected to the plug 92. In its raised position, the platform 90 is received in a recess (84) in the die-holders. The space between the die-sections and the work is evacuated through a pipe (68), Fig. 5 (not shown). If more than one forming impulse is required for a workpiece and vaporizable wire is used, the electrode-head is unlocked and raised for replacement of the wire. In various modifications, Figs. 10-12 (not shown), an electrode may be located at each end of the work (Fig. 10) which is filled with water before the top-electrode is positioned, long work may project below the dies (Fig. 11), and the diesections (330, 332, Fig. 12) may form flat work (30c). Instead of moving both sections, only section (332) may be moved.

Abstract: 1.168,028. Extruding reinforced hose. H. K. PORTER CO. Inc. 16 Aug., 1968 [28 Nov., 1967], No. 39421/68. Heading B5A. [Also in Division F2] Reinforced elastomeric hose is produced by extruding from an extruder A an elastomeric tube, cooling the tube by means of a cooling drum 7 and a fan 8, applying reinforcement Y, e.g. yarn, applying an outer cover O of elastomeric material from an extruder B and curing the thus formed hose in a chamber H, the extruded tubing being internally supported by gas under pressure at least until the curing step has been completed. As shown, the support gas is supplied from a blower 6 and the reinforcement from lappers 10, which preferably operate successively rather than concurrently. A flash heater 11 employing hot air is situated immediately upstream of extruder B and the latter is provided with vacuum means 16 to remove any volatile matter likely to be trapped by cover O. Chamber H comprises solid particles 32, Fig. 3, e.g. glass beads 0À1-0À2 mm. in diameter, which are heated by units 33 and are agitated by, e.g. air or superheated steam, which passes through porous tiles T from a supply conduit 31. The tube may pass one or more times through the fluidized bed of particles 32. Brushes 26 remove any particles adhering to the tube and are arranged to perform a planetary motion about the tube, Fig. 4 (not shown). In modifications, circular knitting machines or braiders may be used instead of lappers 10, an accumulator may be provided immediately downstream of the reinforcing station and this station and extruder B may be duplicated to give multi-ply hose.

Title: Degaussing device for a colour television display tube
IPC: H01J29/00
Filed: 1974-09-10
Abstract: 1480635 Degaussing cathode-ray tube apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Sept 1974 [13 Sept 1973] 39484/74 Heading H4T The degaussing coils 19 (Figs. 1, 2, 5) of a colour television display tube (having vertical colour stripes and a vertically slotted colour selection electrode 5 ferromagnetic material) are supplied with degaussing current by means of a known arrangement (Fig. 3, not shown) which is modified as shown in Fig. 5 by the addition of a capacitor 41 in shunt with the coils 19, the impedance of the capacitor being substantially higher than that of the degaussing coils at the frequency of the degaussing current and substantially lower at the frequency of the line deflection current. With this arrangement, when the coils 19 extend towards the neck of the tube in order to ensure degaussing of the ferromagnetic shield 15 the effect of induced currents of line frequency from the neck mounted line deflection coils 9 on the horizontal deflection of the beam is made symmetrical (relative to the centre of the screen) and may be eliminated by means of a small axial shift of the coils 9. Thus, without the capacitor, the induced line frequency current i varies over a line period as shown in Fig. 4 whereas, when capacitor 41 is shunted across coils 19 the current i varies as shown in Fig. 6. The arrangement is particularly suitable for use with colour display tubes having three "in-line" guns and vertical colour stripes and colour selection slots, where horizontal beam deviations (due e.g. to the vertical component of the earth magnetic field) result in colour impurities and in the present invention the degaussing field in the colour selection electrode is mainly in the vertical direction. The circuit of Fig. 5 (similar to Fig. 3, not shown with the addition of capacitor 41) comprises a double thermistor 30 having two thermally coupled, positive temperature coefficient resistors 35, 37 which, when the television receiver 27 is switched on by closing switch 29 allow a gradually reducing A.C. current to flow in coils 19 which current decreases to a very low value as the resistors become hot. This completes the degaussing cycle and in order to prevent cooling of the resistors 35, 37 a dissipation resistor 39 is provided to maintain them at the desired temperature without a significant current flowing through the coils 19.

Headings F2K, F2S and F2U. [Also in Division F1] A universal joint &c. or shock absorber between a spindle and a body, the latter comprising an hydraulic piston-and-cylinder arrangement feeding a reservoir incorporating a pneumatic expansion chamber, includes a spherical bearing mounting the spindle in the body and a liquid seal between the spindle and body. As shown, a spindle 26 carries at its end arms supporting the ball joints 44 of connecting rods 40 pivoted to pistons 38 reciprocable in cylinders 46 in a body 10, a ball-and-socket joint 20, 22 centring the spindle on a spigot 18 fast within the body. The cylinders 46 feed through pipes 48 to a liquid reservoir 50 having one of its walls 52 consisting of a flexible material and , forming with the end 54 of the body 10 a pneumatic expansion chamber 56. A simple reciprocating pump and control valve 58, Fig. 4 (not shown), in the body 10, feeds liquid between each cylinder 46 and an interior chamber 12, and is actuated by a cam 74 on the spindle 26. The arrangement is such that on relative rotation between the spindle 26 and the body 10, the pneumatic expansion chamber 56 resiliently absorbs shocks due to torsion loading, and the pump-valves 58 act to maintain the pistons 38 at a median position axially of the cylinders 46. A seal 30 between the body 10 and the spindle 26 retains the liquid in the chamber 12. The body 10 may be flanged at 11 for bolting to another shaft, the assembly then acting as a universal joint. Alternatively, the easing shown surrounding the body 10 may be removed and the body may be formed with gear teeth. Again, the body 10 may be held in a fixed position, the assembly then acting as a shook absorber. To retard relative movement between the body 10 and the spindle 26, damping valve 78 may be provided in the pipes 48.
