Title: Improvements in, and relating to, the grinding of safety razor blades
IPC: B24B3/48
Filed: 1932-12-17
Abstract: 412,223. Grinding safety-razor blades. CAM, V. R., 81, Bents Road, Sheffield. Dec. 17, 1932, No. 35850. [Class 60.] In a machine for grinding safety razor blades, of the kind in which the blades are carried on an endless band 10 past grinding wheels 8 arranged at opposite sides of the band and having their axes parallel to it, each side of each edge of a blade being ground at a separate operation, the bearings 6 of the grinding wheel spindles are carried on mountings 5 which are vertically adjustable on housings 3 by means of screws actuated by worm and pinion gearing 24, the housing 3 being horizontally adjustable on bases 4. In the machine shown, the upper faces of the two edges of a blade are first ground successively, the lower faces being then ground in the same order. A rotating cam 18 feeds blades from a holder 17 to a shoot 21 which delivers them to the belt 10, holes in the blades engaging studs on the belt to hold them. After passing through the machine, the blades are removed from the belt by a member 30 having a forked end straddling the belt and provided with rollers 31, which engage the projecting edges of the blades and cause the blades to fall on to a holder comprising rods 33 mounted on a rotatable base 32 so that they may be successively positioned to receive the blades. At the grinding positions the blades pass between upper and lower guide plates which retain them on the band. Water is supplied to the grinding wheels from pipes 37, and is collected in reservoirs 39 from which it is drained by a pipe 40. After grinding, the blades are dried by a blast of air from a nozzle 42 supplied by a blower 44.

Abstract: 522,522. Making caps for electric lamps. BARDY, J. Dec. 8, 1938, No. 35883. [Classes 83 (ii) and 83 (iv)] Punching ; jointing by stamping.-Pins c are secured in the bayonet joint cap of electric lamp bulbs or like by an automatic machine in which each cap is pushed up into one of four sets of jaws 20, 21, Fig. 9, on a work carrier which is indexed to bring the cap between opposing holing- punches 28 which form the holes b, Fig. 2, and then bring it round to station C where pin holders 43 insert the headed pins in the holes and press them outwards until the hole edges are partly flattened as in Fig. 4 to grip and secure them. At the fourth station the cap is released by the jaws opened through rack and pinion mechanism 27 when the diametrically opposite jaws at the first station are closed on a new cap by means of the cam 22. The caps are pushed into the four jaws by a timed cam operated plunger 16. The holing-punches are actuated by another cam 31, the supporting mandrel core 33 being raised into the cap by cam 35. The headed tubular pins gravitate into notches 56 from which a reciprocating feed member 55 brings them in front of pushers 44<SP>1</SP> which press them on holding points 43 at the ends of arms 36 which carry the pins up into the bayonet cap so that a wedge 46 spreads them apart and so drives the pins into the holes with sufficient force to flatten the sides of the holes against the pins. The work carrier is rotated step by step by a Geneva wheel 13, and is held steady by a bolt 51 entering one of the V-slots in the periphery.

Abstract: 1278372 Automatic exchange systems SIEMENS AG 24 July 1970 [25 July 1969] 35920/70 Heading H4K In an exchange having a plurality of concentrators each connected thereto by a smaller number of links than there are subscribers lines terminated at the concentrators, a plurality of concentrator control units are provided, these being connectible as desired to any concentrator via the exchange's speech switching network. The latter KF has subscribers T1, T2, T4 and concentrators KZ1, KZ2 connected to its inlets and local junctors VO, trunk junctors VF, registers R, internal junctors JV and concentrator controllers KS connected to its outlets, the whole arrangement being centrally controlled by Z. When a concentrator subscriber is calling, an indication of this fact is detected by devices A which call in Z whereby a free controller is allotted and then connected via KF and a predetermined link, e.g. the one currently supplying power, to the calling subscriber's concentrator. The controller determines the identity of the calling party who then dials the wanted number into a register or the already seized controller if this is equipped for digit reception. Armed with calling and called party identification the central control takes over the call and the controller and switch path thereto are released. On an incoming call, recognition of a concentrator subscriber results in Z seizing a controller and connecting it to the relevant concentrator. The wanted subscriber is tested by the controller and if he is free a path is cut through KF (by Z) from the incoming junctor to the already seized concentrator link, the controller meanwhile being released.

Title: Improvements in and relating to a polymerisation process and methods of forming catalysts for the same
IPC: C08F4/80
Filed: 1959-10-26
Abstract: Complex ferric salts of polyisoindolines and polyisoindolenines having isoindoline and/or isoindolenine nuclei connected by intervening nitrogen atoms are used as catalysts for the polymerization of ethylenically unsaturated organic compounds. These compounds are used to catalyse the antioxidation of drying oils, particularly those containing conjugated unsaturated fatty acids, e.g. tung oil.  Examples are given of the use of these compounds in (a) a lacquer linseed oil, (b) a mixture of soybean oil and tung oil; (c) a lacquer composition containing an alkyd resin and linseed oil; (d) a mixture of a maleic acid-glycol polyester, styrene and cyclohexanone peroxide and (e) the polymerization of acrylonitrile or vinyl acetate in the presence of cyclohexanone peroxide.ALSO:Complex ferric salts which are used as polymerisation catalysts are prepared by heating at a temperature of 100-200 DEG C. phthalic anhydride, phthalodinitrile, benzene tricarboxylic acid, or benzene tetracarboxylic acid with urea and a ferrous salt in the presence of an oxidising agent comprising ammonium nitrate and/or oxygen and in the presence of a catalyst comprising ammonium molybdate.  The compounds may alternatively be prepared by the oxidation with air or oxygen of complex ferrous compounds of polyisoindolenines.  The complex ferric salts are salts of polyisoindolenines or polyisoindolenines having isoindoline and/or isoindolenine nuclei linked by intervening nitrogen atoms. In examples: (a) urea, phthalic anhydride (or dinitrile), ammonium nitrate, ferrous sulphate are reacted with oxygen in the presence of ammonium molybdate to give ferric-bis-(ansadihydroxy-diamino-isoindolino) - dihydroxy-diaminodiaza-cyclotetraisoindoline; and (b) ferro-phthalocyanine, phthalodinitrile are reacted with oxygen in the presence of ammonium molybdate to give a ferric salt of polyisoindolenine.  In general the nature of the products is obscure but they are iron compounds containing a plurality of isoindoline and/or isoindolenine nuclei which are connected by intervening nitrogen atoms (generally imino groups) which may be substituted by amino groups, hydroxy groups or methoxy groups.

Title: Improvements in rotary wing aircraft
IPC: B64C27/54
Filed: 1956-11-29
Abstract: 834,587. Rotary wing aircraft. BOLKOW, L. Nov. 29, 1956 [Dec. 7, 1955], No. 36548/56. Class 4. A device for automatically controlling the pitch angle of a rotary wing aircraft rotor, wherein a correcting force is exerted on the pitch control means, of such magnitude that it can be overcome by the pilot, comprises an energy storing device, the force exertable by which is made operative by release means under predetermined flight conditions. In one form, Fig. 1, a lever 4 is pivoted on the same axis 11 as the pilot's collective pitch lever 1. The rod 5 of a piston 6 is pivoted to lever 4, the cylinder 7 being pivoted to the aircraft at 14. The piston contains two ducts closable by non-return valves 10, 11, and a spring 13 is disposed between the piston and the cylinder wall 12. Conduits 15, 16, 17 lead from the cylinder to a valve 22 and a fluid container 19 with a riser 20. The valve 22 is urged towards the open position by a spring 24, but is normally held closed by an electromagnet 23 acting on the valve arm 22<SP>1</SP>. When the pilot puts the lever 1 in a position suitable for helicopter flight, an abutment 2 on lever 1 contacts abutment 3 on lever 4, and piston 6 is moved to the right, compressing spring 13, fluid flowing past valves 10 and 11. The piston is unable to return, since valves 10, 11 are one way valves. If the rotor speed falls below a predetermined minimum, a centrifugal device 29 opens a switch 28, deenergising the electromagnet 23. Valve 22 opens, and the piston 6 moves to the left until spring 13 is unstressed. If this is not opposed by the pilot, the collective pitch lever 1 is moved to a position suitable for autorotation. A regulator 21 in conduit 15 limits the speed of piston 6. In a further embodiment, lever 4 operates a rack and pawl device and compresses a pneumatic cushion. The device is released when the pawl is raised by a rotor speed responsive device. An acoustic or optical signal may be given at the same time, or the lever 1 may be vibrated. In a further embodiment, lever 4 compresses a spring which is held compressed by a solenoid and armature device. The solenoid is de-energised so that the spring acts on the collective pitch lever, either when the rotor speed falls below a predetermined value, or when the engine induction manifold pressure rises above a certain value. The combustion chamber pressure of a gas turbine or the torque of the driving motor can also be used as control quantities.

Two meshing gears 8, 9 have crank pins 8', 9' which engage a hole and a slot in a weft inserting needle 2; the resulting revolution of the crank pins in opposite directions causes the eye 2' of the needle to pass through the shed along a path 13a and to return along a path near the fell. Knitting selvedges, Fig. 10. As shown, a selvedge thread 31 is raised above the weft thread 38 by a guide eye 5 so that a loop of selvedge thread is drawn over the weft thread as the knitting needle 3 retracts; a loop of weft is formed around the loop of selvedge thread as the weft inserter 2 retracts, resulting in the selvedge thread being knitted through the looped ends of the picks. The weft inserting needle is arched at 2" to clear the eye 5. Alternatively, the loops of weft may be knitted together, with or without a selvedge thread. Smallware looms. A number of weaving units may be mounted in a row, with driving shafts extending along the row.

Filed: 1971-08-04
Abstract: 1352720 Valves JET SPRAY COOLER Inc 4 Aug 1971 [31 Aug 1970] 36580/71 Heading F2V A beverage dispenser has inlet passages 18, 20, 22 supplied respectively with flavour syrup, carbonated water and sweet water, and each passage defines a seat 27 for a respective valve member 28. The valve members have respective stems 30, 36, 38 and are biased to their closed positions by springs 70. The stems are intended to be operated in various combinations by a lever 14 connected by rod 56 to a pivoted handle 12 disposed adjacent outlet nozzle (16) to be actuated when a cup is placed under the nozzle. Stem 30 directly abuts the lever 14 and will thus always be operated when lever 14 is moved clockwise. Stems 36, 38, however, extend through slots in lever 14 and abut the lever 14 via washers 80, 82 which are selectively removable, together with spacers 76, 78, whereby the stems can be prevented from responding to movement of the lever. The valve members can thus be displaced by the lever to dispense high, low or non-carbonated beverage, and depression of the stems 36, 38 releative to the lever allows plain sweet or carbonated water to be dispensed. The syrup flows to the nozzle via passage 40, the carbonated water via passages 42, 46 and the sweet water via passages 44, 46. Adjusting screws 90, 92 control flow through passages 40, 42, and a replaceable flow regulating washer (110) in a sweet water supply fitting (100) ensures a constant flow of sweet water. The push handle could be replaced by a solenoid.

Title: Improvements in or relating to borate pigments
IPC: C09C1/00
Filed: 1961-10-12
Abstract: A white barium zirconium borate pigment BaO.ZrO2.B2O3 is prepared by heating a mixture of either (1) zirconium dioxide and barium metaborate or compounds convertible to such upon heating, e.g. zirconium sulphate tetrahydrate and barium sulphide, carbonate or hydroxide with boron trioxide or boric acid, or (2) barium metazirconate and boron trioxide or a boron compound convertible to the trioxide upon heating.  The heating is preferably carried out between 800 DEG -1300 DEG C. for 10 mins.-24 hours.  The zirconium dioxide used may be either the mineral baddeleyite or it may be prepared by precipitation in the hydrous form from zirconium sulphate tetrahydrate or zirconium tetrachloride solutions.  The zirconium sulphate tetrahydrate may be prepared by recrystallizing precipitated basic zirconium sulphate from sulphuric acid.  The barium metaborate used may be precipitated by reacting solutions of barium sulphide or hydroxide with sodium tetraborate.  Example 1 refers to the above stoichiometric quantities of barium carbonate, boric acid and zirconium dioxide being mixed in a mortar and pestle and fired at 1050 DEG C. for one hour after which the cooled product was reground and fired for a further hour at 1050 DEG C.  X-ray analysis of the resulting crystalline product indicated that a compound had been formed.  Example 2 refers to a ground mixture of barium carbonate, boric acid and recrystallized zirconium sulphate tetrahydrate being fired at 1100 DEG C., reground p  and refired at 1100 DEG C. for a further half hour.  Example 3 refers to hydrous zirconium dioxide being precipitated from zirconium sulphate tetrahydrate solution with sodium hydroxide.  A slurry of the hydrous zirconium dioxide and boric acid was then gently refluxed and barium hydroxide added and the refluxing continued for two hours.  The resulting wet cake was dried at 140 DEG C. and fired as in Example 1.  Example 4 refers to the barium zirconium borate compound being prepared together with excess barium metaborate.  Example 5 refers to the barium zirconium borate compound being prepared together with excess zirconium dioxide. Specifications 813,228 and 879,499 are referred to.

Abstract: 995, 018. Measuring velocity electrically. T. KAIHORI. Oct. 1, 1962 [Oct. 9, 1961; Oct. 23, 1961], No. 37098/62. Heading G1N. [Also in Division H1] Apparatus for determining the magnitude and direction of the ground speed of a craft comprises means for measuring the e.m.f. induced in the horizontal electron stream of a vacuum tube as it cuts the vertical components of the earth's magnetic field. As shown, (Figs. 2, 3), a triode valve 100 and its anode return lead 3 are mounted horizontally inside a magnetic shield comprising highpermeability plates 5, 6, 7 with lead 3 passing through an aperture 11, and the valve in apertures 10, the vertical plate 7, being in line with the position normally occupied by a control grid. The assembly is carried by the craft moving with a velocity v in the direction shown, whereby an e.m.f. e, proportional to v, is induced in lead 3 opposing the HT supply 101 and a similar e.m.f. e affects the space charge at the nominal grid aiding the anode/cathode potential difference. The grid e.m.f. is equivalent to ue volts in the anode circuit, giving an additional e.m.f. of e (Á-1) in the anode circuit, proportional to the velocity v. This is converted to an alternating current signal in the anode circuit by a rotating plate 8 and fed through tuned circuit 14 to a measuring device at terminals 16. A coil may also be wound round plate 7 to provide information of the instantaneous value of the intensity of the vertical component of the earth's magnetic field, and this is combined with the signal at terminals 16 in a ratio-meter to eliminate the effect of variations in the magnetic field. Another embodiment employs a double triode valve 20 (Fig. 4) with a high-permeability grid 26, connected to terminals 16 via a push-pull transformer. Two such devices may be mounted on the craft at right angles to determine the velocity components in perpendicular directions, which may be combined to determine the actual direction of travel, and integrated to determine the distance travelled.
