Abstract: 714,744. Moulded commutators for dynamo-electric machines. GENERAL MOTORS CORPORATION. June 3, 1952 [June 28, 1951], No. 13904/52. Class 35 [Also in Groups V and XXII] A moulded commutator is made by forming a series of longitudinal ribs inside a metal tube, moulding a plastic centre round the ribs, and slitting the tube between the ribs to form the segments. The blank tube 20 is placed in a press tool, the bottom plate 21 of which has a series of dove-tail shaped recesses 23, the upper plate being suitably widened at 26a to receive the tube. A broaching tool 37 having a spigot part 38 which fits inside the tube and a number of spaced dove-tail shaped teeth 39, is forced down through the tube, the metal displaced by the teeth 39 to form the moulding ribs 31 being forced into the holes 23 to form the risers 32. The central core is moulded into the tube in a mould 50 having a cover 55 and a bottom plug 52 with a reduced shank 53. The tube is placed in the mould bore with the risers 32 resting on its top surface, its interior is filled with plastic material and when the cover is replaced the curing heat is applied. After moulding, a circular groove is turned in the risers and filled with a ring 62 of weld metal to which the armature connections 64 are welded. Finally the commutator is separated into segments by longitudinal slitting and machined true.

Abstract: 162,200. Eucken, E. May 20, 1920. Tension arrangements. -Relates to means for tensioning belts, ropes , or chains in a driving- gear by the weight of a floating countershaft and its supporting-frame, whereby excessive bearing- loads, slip, and the necessity for belttightening are avoided. A countershaft b bears in a doubly-jointed frame d, e, mounted on a pivot g preferably on the same base as the source of power a, so that the said countershaft is f r e e to assume any position between a r c s of radius d+e and e-d and centre g. The driven belt &c. c runs approximately at right-angles to the motor base. If, as would be the case in the configuration shown in full lines, the tensions in the driving and driven belts &c. due to the weight of the countershaft pulleys and frame alone are unsuitable, they may be adjusted by an auxiliary weight h connected to the frame by a rope passing over pulleys i, k.

Title: Improvements in carburation systems for internal combustion engines
Inventor: SCHMID WERNER
IPC: F02M7/11
Filed: 1967-03-28
Abstract: 1,117,268. Carburetters. SOC INDUSTRIELLE DE BREVETS ET D'ETUDES. March 28, 1967 [April 8, 1966], No.14077/67. Heading F1B. In a curburetter in which fuel from a constantlevel chamber 5, Fig. 1, is sucked into an inlet passage 1 having an air filter 2, a single mechanism 9, 26, 21 connected to the main throttle 4 actuates three different means for venting the chamber, corresponding to normal operation, reduced fuel flow and idling or stoppage. Normal operation: With butterfly valve 4 in an intermediate position (as in Fig. 1), a spring 22 biases the two non-return valves 16, 20 on their seats 15, 19 and on the shoulders 23, 24 of rod 21 thus closing the passages 14, 18. The top part of chamber 5 communicates solely via passage 17 (or alternatively 17b) with a negative pressure zone of the inlet passage 1 thereby reducing the rate of mixture flow through jet 7. Idling operation: Valve 4 is closed as in Fig. 2 (not shown) and the screw 27 on lever 9 moves lever 26 anti-clockwise into contact with abutment 33 whilst rod 21 and valve 20 are raised against spring 22. Chamber 5 is vented via passages 13, 18 to atmosphere whilst passage 17 remains open. Full load operation: When valve 4 is opened as in Fig. 3 (not shown) beyond the position shown in Fig. 1 the spring-loaded finger 30 on lever 9 moves lever 26 clockwise thereby lowering rod 21 and valve 16 against spring 22. Chamber 5 is then vented to atmosphere via passages 13, 14 and the air entry 3 in passage 1. Thus the pressure at the top of chamber 5 is the same as that in the air entry 3 and is not reduced as in the case of normal operation. In another embodiment similar venting means are applied to a carburetter having a pistonoperated auxiliary throttle element 34, Fig. 4, actuated by the vacuum present in passage 35. Throttle 34 moves a tapered needle 36 in a calibrated orifice 37 between chamber 5a and throttling zone 6a.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 28, 1934.] [Class 131.] In hair-waving apparatus of the kind in which a heating element is arranged either to have a tress of hair wound around it or is arranged to surround a tress of hair which is wound on a curler, the element is heated by the combustion of a fuel air mixture which is passed over a known combustion catalyst, e.g. platenized asbestos, housed in the element. The fuel employed may be a gas, such as hydrogen, methane or acetylene, or a vapour, such as alcohol or petrol vapour, and the catalyst may be in the form of pellets strung on a wire. The heating elements may comprise a hollow curler or a U-shaped or hinged clip provided with a chamber or chambers for the catalyst and with an inlet and outlet for the fuel air mixture and the products of combustion respectively. Each heating element, e.g. the curler 11, Fig. 6, may be provided with a separate generator for fuel mixture comprising a perforated cup 25 containing absorbent soaked in volatile fuel through which air is drawn by a suction device 28 connected to the outlet of the element, or a series of elements may be connected by pipes 9, Fig. 1, to a single generator 1 containing a reservoir 4 for liquid fuel through which air is forced by a pipe 6. The generator 1 may be provided with a compartment 3 containing material, e.g. activated charcoal, for absorbing the products of combustion, the compartment being provided with nipples 8 connected by pipes 10 to the outlets of the heating elements. In a modification, the generator is mounted on a stand 30, Fig. 8, the fuel reservoir 4 being secured to the bottom of a gas-tight casing 32 carried by a hollow frame 33 on which is mounted the exhaust chamber 3.

Title: Process for preparing dispersions of hydrocarbon resins and products obtained thereby
Inventor: HUNTER EDWARD ALLEN
IPC: C09K23/00
Filed: 1957-05-06
Abstract: Aqueous dispersions of resins obtained from polymerized steam-cracked petroleum distillates are prepared by mixing the resins at a temperature below the boiling point of water, and above the melting point of the resin with a mixture of two surface active agents (1) polyoxyalkylated alkyl phenol or alcohol, of formula R(OCHR1,CHR1)nOH, where R is an alkyl or aralkyl group, R1 is an alkyl group or hydrogen, and n is an integer of 4 to 10, and (2) a condensation product of a fatty amine and ethylene oxide of formula <FORM:0818735/IV (a)/1> where R is an aliphatic hydrocarbon radical having 10 to 20 carbon atoms and x and y are integers whose sum is from 2 to 10, and adding water till phase inversion takes place.  The resins are obtained by polymerizing distillates having a boiling range of 30 DEG  to 280 DEG  C., at a temperature of 0 DEG  to 65 DEG C. and in the presence of 0.25 to 2.5 per cent of a Friedel-Crafts catalyst.  The catalyst is removed by adding methyl alcohol, filtering, washing, and finally stripping from unreacted hydrocarbons and low molecular weight oils.  The polyoxyalkylated alkyl phenol is preferably an octyl phenoxy polyethoxy ethanol with 5 to 10 ethylene oxide units, and the condensation product is a compound in which R is an unsaturated aliphatic hydrocarbon group having 18 carbon atoms, derived from soya oil, and x + y is 2.  Emulsifiers such as dodecyl or octadecyl trimethyl ammonium chloride, a polyalkyl amide of lauric acid, or sorbitan trioleate may be included in the mixture of resin and surface active agents and in a modification, paraffin wax from 10 to 25 weight per cent may be mixed with the resin before admixture with the surface active agents.  Water is added portionwise to the mixture of molten resin and emulsifying agent to form a water-in-resin emulsion which is inverted by the rapid addition of further water to give a dispersion with 50 per cent total solids. The dispersion which may include dyes, pigments and fillers, may be used to coat or form laminates with, fibrous materials such as paper, or cardboard.  Specification 737,525 is referred to.
