Title: Improvements in the fuel injection pumps for internal combustion engines
Inventor: EYZAT PIERRE
IPC: F02M41/06
Filed: 1965-06-24
Abstract: 1,116,978. Fuel injection pumps; distributing valves for L C. engines. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. June 24, 1965 [June 24, 1964], No. 26885/65. Headings F1A and F1B. In a fuel injection pump delivering fuel to the cylinders of an I. C. engine to provide a main injection and a secondary injection prior to the main injection, fuel distribution is controlled by a rotary and axially displaceable distributer piston in a bore in the pump body. The pump bore is provided with an annular groove 8, communicating with the cylinders 9 of cam actuated pumping plungers 10, which communicates with inlet ports 4a, 4b, 4c, 4d in the bore by means of grooves 5a, 5b, 5c in the distributing piston. The discharge ports 7a, 7b, 7c, 7d in the bore, communicating via injection passages with the engine cylinders, are communicated with the groove 8 via the grooves 6 and 14 and grooves 5b and 5c. The groove 14 provides the secondary injection via a discharge port, 7d as shown, substantially half an engine cycle prior to the main injection through the port via groove 6. The charges at the main and secondary injections are varied by axial displacement of the distributing piston accompanied by angular adjustment to provide constant timing for the beginning of the main injection. As the total charge increases the charge at the secondary injection is decreased. The groove 14 may be arranged to provide at small charge a secondary injection which begins and ends simultaneously with a main injection, as shown, to give equal main and secondary charges. At substantial charge, Fig. 2A (not shown), the secondary injection occurs after the beginning of a main injection and terminates simultaneously. In a further embodiment, Fig. 5A (not shown), the secondary injection starts simultaneously with a main injection and terminates prior thereto, the trailing edge of the secondary groove (14) breaking communication with the discharge port (7d). A further groove (19) is provided to connect the discharge port (7d) to the intake pressure simultaneously with the end of the main injection. The specification includes formulae for determining the angles of the secondary groove and further groove to provide desired injection characteristics. The distributing piston of the present invention may be employed in the injection pump described in Specification 994, 950.

Title: Decorative devices and methods for making the same
Inventor: GREEN HARRY MICHAEL
IPC: A41G1/04
Filed: 1959-08-06
Abstract: 910,529. Ornamenting. GREEN (POLYFOIL) Ltd. July 19, 1960 [Aug. 6, 1959], No. 26913/59. Class 93. Decorative devices are made from a strip or sheet of foil, e.g. aluminium foil, by slitting it into a number of narrow strips while it is being advanced, and deforming the narrow strips simultaneously, whilst advancing them in the side-by-side relationship which they assume after slitting. The slitting operation may be stopped periodically to leave transverse portions of foil joining the narrow strips together. The second operation may consist in drawing the narrow strips across one or more edges disposed across the direction in which they are drawn to cause them to curl when released or in transversely corrugating the narrow strips. The foil may be of aluminium or other metal, of plastic, which may be metal-coated, of two or more layers of the same or different materials bonded together, e.g. aluminium foil and cellulose film, or may consist of unbonded films of the same or different material. The foil may be coloured on one or both surfaces in one colour or in longitudinal or transverse strips of different colours, and may carry printed wording, designs or devices. In a modification, the device may be made from a wide sheet to serve as covering material. As shown, aluminium foil 1 unwound from a reel 2 is slit into strips 1a by spaced blades 3 projecting into grooves 4a in a supporting roller 4, the blades 3 and roller 4 being movable away from each other, e.g. by raising the blades 3, to interrupt the slitting without interrupting the feed of the foil 1 to provide unslit transverse portions 1c. The narrow strips 1a are deformed by passage over the edge 5a under tension exerted by the driven feed rollers 6, tensioning or braking devices being applied to the foil fed from the reel 2. The roller 4 may be omitted and grooves provided in the edge 5a into which the blades 3 may enter. The edge 5a may be omitted and corrugations provided on the rollers or on separate rollers. The corrugations may be interrupted across the unslit portions. One or both unslit end portions may have a length of thread connected thereto.

Title: Process for the manufacture of n-aryl-glucamines
IPC: C10B1/04
Filed: 1935-09-30
Abstract: N-Arylglucamines are prepared by the catalytic hydrogenation of monoses in the presence of primary amines of the benzene series at a temperature of 90--140 DEG  C. and a pressure of 15--20 atmospheres, the monoses being used in the dissolved state and nickel employed as the catalyst.  The products are stable crystalline compounds, of use as intermediates for the manufacture of pharmaceutical substances. According to the examples: (1) a solution of glucose and aniline in aqueous methyl alcohol is heated with hydrogen in an autoclave in the presence of a catalyst prepared by reducing nickel carbonate mounted on kieselguhr, and phenyl-glucamine separated from the product; (2) in the same way, glucose and p-toluidine yield p-tolyl-glucamine, glucose and 4 - acetylamino - 3 - amino - 1 - methylbenzene give 4 - acetylamino - 3 - glucamino - 1 - methylbenzene, and arabinose and mono-acetyl-o-phenylenediamine produce o-acetylamino-arabinaminobenzene.

Title: Improvements in and relating to electric motors
IPC: H02K17/04
Filed: 1932-09-28
Abstract: 406,777. Induction machines. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Morrill, W. J. ; 2317, South Wayne Avenue, Fort Wayne, Indiana, U.S.A.) Sept. 28, 1932, No. 26966. Convention date, Sept. 29, 1931. [Class 35.] A single phase motor has displaced primary windings which are energized in parallel for starting one of which produces a sinusoidally distributed flux and another a flux having a large non-fundamental component, and a secondary winding which is responsive only to sinusoidally distributed primary flux, and means are provided to cause the primary member to produce fluxes only of substantially sinusoidal distribution for running conditions. In the form shown in Fig. 7, the main primary winding consists of sections 11, 12 both of which are used for running but 11 only for starting, and the auxiliary primary winding consists of sections 30, 31 parallel connected for running section 30 only being used for starting, whilst the secondary 14 preferably consists of short circuited coils in skewed slots connected at one end to a common end ring, the coils having a pitch approximately ten fourteenths that of the full pitch coil section 11 of the primary. The sections 11, 12 are wound in the same axis, have the same effective number of turns, but whereas 11 is a concentrated full pitch coil arranged so that it produces an approximately uniform flux across the pole, winding 12 is so arranged that it produces a flux which when combined with the square wave flux of winding 11, produces a substantially sinusoidal resultant, and as the secondary is non-inductive to non-sinusoidal fluxes, the arrangement is equivalent to series reactance in the main winding circuit for starting up. The auxiliary winding section 30 produces high leakage fluxes when used alone and the voltage across the condenser is thereby raised; alternatively however, the condenser may be in series with a single auxiliary section permanently in circuit, or the condenser may be omitted and the auxiliary winding disconnected on reaching normal speed. As a further alternative, winding 27, Fig. 6, is similar to winding 11, Fig. 7, and is connected in parallel with a sinusoidal flux producing winding 28 for starting but is subsequently disconnected.

Title: Improvements in or relating to filaments comprising a hydrolysed interpolymer of ethylene and vinyl organic ester
IPC: D01F6/04
Filed: 1945-10-17
Abstract: Dry-spun artificial filaments of substantially completely hydrolysed ethylene/vinyl organic ester interpolymers are given a high tenacity and decreased brittleness by heating them for at least 5 hours in a taut condition and at a temperature below, but not more than 20 DEG C. below the temperature at which the filaments will adhere to one another and then drawing the heat-treated filaments to at least twice their original length.  The interpolymers, which are hydrolysed before spinning, contain ethylene and the vinyl ester in a mol. ratio of from 1 : 1 to 5 : 1 and specified vinyl esters are the formate, acetate, propionate, butyrate, stearate, benzoate, cyclohexanoate, isobutyrate, palmitate, myristate, toluate and naphthoate.  The filaments are spun from solutions of the polymers in, for example, a mixture of trichloroethylene and ethanol, a primary aliphatic alcohol or a primary or secondary aliphatic amine.  After the heat treatment and prior to drawing, the filaments may be soaked in water.  The filaments may be heated in fluid baths of steam, air or oil.  In an example, dry-spun hydrolysed ethylene/vinyl acetate interpolymer filaments are heated in an air oven at 105-110 DEG  C. for 24 hours, and subsequently drawn in saturated steam at a draw ratio of 8.33 : 1.
