Title: Method of producing a platinum group metal or alloy electrode
Inventor: AOKI KIYOSHI
IPC: C25B11/08
Filed: 1967-04-28
Abstract: 1,134,620. Electro-depositing or chemical plating platinum group metals or alloys. AJINOMOTO CO. Inc. April 28, 1967 [May 19, 1966], No. 19810/67. Headings C7B and C7F. A platinum group metal electrode suitable as an anode in alkali metal chloride electrolysis in a mercury cell is produced by (a) forming on a clean surface of a metal-containing base such as Ti, Zr or magnetic iron oxide an alloy layer comprising a Pt-group metal or alloy, i.e. Pt, Rh, Ir, Pd, Os and/or Ru, and an alloyable non-Ptgroup metal or alloy, e.g. Cu, Ni, Au, Fe, Ag, Pb, Mn and/or Co, (b) dissolving the non-Ptgroup metal or alloy from the alloy layer and (c) plating the resulting Pt-group metal or alloy coated base with the same or a different Pt-group metal or alloy. Step (a) may be effected by electro-deposition using a plating bath containing ions of the required Pt-group and non-Pt-group metals; initially the base may be plated with the Pt-group metal. A Pt electro-plating bath is specified as comprising 5 g/l H 2  Pt Cl 6 .6H 2 O, 45 g/l NH 4 H 2 PO 4 , 240 g/l (NH 4 ) 2  HPO 4 , with or without 0À4 g/l Cu Cl 2  (for Pt-Cu plating), the cathode current density being 0À3 A/dm<SP>2</SP> . Alternatively, the base surface may be electro-plated with the Pt-group metal, followed by plating with the non-Pt-group metal, heating e. g. at 700‹ C. in an inert gas to diffuse the layers and quenching. Conventional electro-plating baths are specified for Cu, Ni, Ag, Au and Fe. Step (b) may be effected chemically, e. g. by immersing the coated base in an acid such as HNOs, HCl or H 2 SO 4  or alkali such as alkali metal hydroxide, or electrochemically, e. g. by electrolysing an alkali metal chloride of concentration 300 g/l using the coated base as anode and mercury as cathode with an anode current density of 100 A/dm<SP>2</SP>. Step (c) may be effected by electro-plating as in (a) for Pt-group metal, or chemical plating such as by chemical reduction or enamelling, e.g. using a solution comprising 2À6g H 2  Pt Cl 6 À6H 2 O or 0À26g Rh Cl 3 .3H 2 O or 0À18g Ir Cl 3 .3H 2 O, 0À04 ml each of 35% HCl and 25% H 3  BO 4  solution, 20 ml ethanol, 10 ml lavender oil and 8 ml turpentine oil, and heating; the latter may also be used for step (a) and may additionally contain 0À21g Cu Cl 2  (0À1 Cu) for Pt-Cu enamel or 0À1g NiCl 2 .6H 2 O for Pt-Ni enamel. The base may be initially cleaned with boiling HCl, or (KCl+NaCl) fused salt followed by 50% H 3 PO 4 .

Title: Improvements in or relating to automatic firearms
IPC: F41A3/46
Filed: 1934-07-09
Abstract: 437,978. Automatic guns. STECKE, E., 37, Ul. Wilcza, Warsaw, and PANSTWOWE WYTWORNIE UZBROJENIA W WARSZAWIE, Warsaw. July 9, 1934, No. 20112. Convention date, July 8, 1933. [Classes 92 (ii) and 119] Relates to automatic guns in which a short rearward movement of the breech block I caused by recoil of the cartridge case imparts kinetic energy to a member 3 slidable in the block to first unlock it and then by impact move it rearwards to withdraw the cartridge case. According to the invention, energy is imparted to the member 3 by levers 2 which are rockably and slidably mounted in the breech block and which engage inclined recesses 8 in the gun casing to lock the block on firing. Further, the short rearward movement of the breech block on discharge causes the levers 2 to rock and impart a kick to the member 3 which at the end of its sliding movement in the block releases the levers 2 and strikes against a pair of levers 5 which forcibly open the breech by bearing against projections 6 on the gun casing. In the gun shown, the member 3 constitutes the firing pin and the levers 2 bearing thereon can only slide inwardly for unlocking under the action of the inclines 8 when the member is about to engage the levers 5. A single spring 4 serves for breech closing and firing.

Title: Improvements in or relating to apparatus for measuring electric currents
IPC: G01R13/04
Filed: 1927-07-30
Abstract: 299,749. Reyrolle & Co., Ltd., A., and Clothier, H. W. July 30, 1927. Electromagnetic current meters. - Instruments for measuring electric currents, particularly heavy currents of short duration such as fault or overload currents operating the circuit-breaker of a feeder of a supply station, comprise a plunger or other movable member acted upon by a coil and means for obtaining a record of the energy or velocity of the impact of the plunger with a body in its path. A brass tube F sliding upon a tube E carries a plunger G of soft iron or steel, preferably laminated. A coil D operating the plunger G when the current rises to a value sufficient to lift the plunger is connected in circuit directly or indirectly. A hard steel point G' on the plunger G strikes a button K of soft metal such as lead, the size of the indentation forming a record of the impact and so of the operating current. The coil D may be supplied by a current transformer, the primary of which is constituted by, or in series with, the feeder and, to give the instrument a straight-,ine law, this transformer may have an air gap in its core and the frame B may be non-magnetic so that the flux has no iron return path. To renew the impact surface, the button K may be moved after each impact, the button being eccentrically pivoted or slidably mounted, or removal of the button may be facilitated by a screwed connection with a block J on a removable cross-bar H. Oscillations of the plunger are prevented by a ball valve L retarding downward movements.

Title: A mechanical race game apparatus
IPC: A63F9/14
Filed: 1919-08-19
Abstract: 137,771. Bolas, J. Aug. 19, 1919. Race games, mechanical.-Objects such as horses, ships, tanks, &c. are carried along a race course and are accelerated, or may in some instances be both accelerated and retarded according to chance by mechanical connexions controlled by a rolling weight and rotating top, each object as it reaches the winning post hoisting its number or other distinguishing symbol. The horses &c. 9 are attached by spring clips to endless chains 10 passing over a series of sprocket wheel 8, 11 driven by gearing 5, 6 from a hand-operated shaft 3. The horses start from a gate 15 and travel at equal speeds until a ball is dropped into a casing 19 containing a top 17 set in rotation by a finger-piece 21. The ball rolls on to one of a number of trays 22 each supported on a lever 23 and connected by a bell-crank lever 25, rod 26 and lever 27 to a sliding clutch member 28, Fig. 5, on the shaft 3, the clutches being equal in number to the horses. The weight of the ball on the tray pute the corresponding clutch member 28 into driving connexion with its pinion 29 which then drives the corresponding sprocket wheel 8 and its horse at an increased speed, this acceleration being permitted owing to the presence of a ratchet wheel and pawl mechanism 30 within the wheel 8. Ribs on the rotating top knock the ball from one tray 22 to another, thus transferring the acceleration from one horse to another. When the leading horse arrives at the finishing point it knocks back a number plate 31 clear of a catch and the number plate is drawn up vertical guides by means of weights or springs. During its upward movement, the number plate displaces another catch and thus allows a bar 36 to swing down so as to obstruct the upward movement of the remaining number plates. In a modification, the horses are capable of retardation in addition to acceleration, by suitable duplication of the clutch mechanism and by arranging the free wheel action within the wheels 8 to operate in both directions, two trays 22 being then used with each horse.

Filed: 1975-05-15
Abstract: Novel 1-[N-(p-fluorobenzoylpropyl)-4-piperidyl]ureas of the formula I below, in which R is a hydrogen atom, an acetyl group, an alkyl group with 1 to 3 carbon atoms or the phenyl group, are prepared by reacting a correspondingly substituted N-(4-piperidyl)-2-imidazolidinone with a p-fluorobutyrophenone which has in the  omega  position a group which can be eliminated under the reaction conditions. The products of the process can be converted into their physiologically tolerated acid addition salts. It is additionally possible for resulting compounds of the formula I in which R is hydrogen to be acetylated by reaction with acetyl chloride or acetic anhydride. The novel compounds show the typical range of effects of the neuroleptics and can therefore be employed as CNS-depressant agents, sedatives and tranquillizers. <IMAGE>
