Title: Charge forming apparatus
IPC: F02M7/10
Filed: 1973-07-12
Abstract: 1389357 Spray carburetters BORG-WARNER CORP 12 July 1973 [18 Aug 1972] 33388/73 Heading F1B Charge forming apparatus comprises a body member 21 having an air induction passage 22, 23, 24 and fuel passage means and including a throttle valve 36, the fuel passage means being adapted for circulating a fuel stream through the body and including a fuel channel e.g. 56, 57 extending across the induction passage and having a gap portion facing substantially upsteam, permitting impingement of an air stream upon the fuel stream in the fuel channel, the configuration of the gap portion defining a surface for deflecting fuel from the passage into the induction channel. The apparatus forms three fuel streams, (a) an idle stream which flows from nozzle 56 across gap 54 to receiver 57, (b) a mid-range stream which flows from nozzle 81 across gap 53 to receiver 82 and (c) a full throttle stream which flows from nozzle 98 across gap 52 to receiver 99. The nozzles are supplied with fuel through a fitting 41 and nozzle holders 62, 83 and 101. The receivers are mounted for longitudinal adjustment in holders 71, 92 and 109, which each communicate with a fuel outlet 47 for surplus fuel. Figs.6 and 6a show the arrangement of gap 53, some of the fuel flowing across the gap is deflected out of the stream by the air-flow which is normal to the nozzle and receiver axis. The total fuel delivery from all three nozzles provides idle fuel requirements at low rates of air-flow and then a constant air/fuel ratio at higher rates of air-flow. In a modification, Fig. 9a and 9b, the nozzle telescopes into the receiver and is formed with a diametral slot 136, 137 opening into the upstream and down stream walls of the nozzle. In a second modification the nozzle is cut away to half its diameter on the upstream side only, for a length similar to the slot length of Fig.9. In a third modification the apparatus has a single fuel channel and an idle orifice, Figs.1 and 12 (not shown). An auxiliary air passage by-passes the region of the air induction passage in which the single fuel channel is situated. In a fourth modification, the overall height of the apparatus is reduced by omitting the choke valve, Fig.16. Fuel enrichment for starting is provided by a channel 251 which extends across the air induction passage downstream of the throttle valve. The channel 251 consists of a tube, the upper part of which is cut away to half the tube diameter and a similarly shaped surrounding sleeve. Rotation of the sleeve relative to the tube enables the degree of enrichment to be varied.

Title: New methods of textile ornamentation
Inventor: BRAGG WILLIAM
IPC: D06Q1/08
Filed: 1957-10-30
Abstract: Differential colour effects on textiles or films of aromatic polyesters are obtained by subjecting selected areas of the textile or film, preferably heat-set, to mechanical pressure action and then dyeing in the presence of, or in conjunction with the application of, a dyeing assistant, such as trichloroethylene, ethylene dichloride, chlorobenzene, chloroform, benzyl alcohol, ethyl benzoate, methyl salicylate, phenyl acetate, acetophenone, p-phenyl phenol, o-phenyl phenol or diphenyl, which causes aromatic polyesters to take up dyes more easily.  The dyeing assistant is dissolved or emulsified in the dyebath, although when trichlorethylene is employed as the dyeing assistant, the dyed textile or film may be suspended in the vapours of this product. Two-colour effects may be obtained by effecting an additional dyeing operation prior to the application of mechanical pressure. In a modification, the textile or film is first dyed, then subjected to the mechanical pressure action and finally treated with the dyeing assistant.  Dyeing may be effected on the winch, jigger or padder with disperse, basic, organic solvent-soluble, solubilised acetate or free leuco vat dyes or with azoic combinations. Mechanical pressure is preferably applied with a patterned calender, although a press, stamp, brush or the compressive-shrinkage apparatus of Specification 752,191 may also be used.  Loose dye is preferably removed by soaping and rinsing or by treatment with hydrosulphite solution.  Numerous examples are given.  Specifications 759,595, 759,625, 812,697 and 828,947 also are referred to.

Title: Improvements in and relating to conveyor systems
Inventor: PENN ARTHUR
IPC: B65G47/51
Filed: 1962-09-06
Abstract: 1,047,528. Storage hoppers. SIMONACCO Ltd. Aug. 21, 1963 [Sept. 6, 1962], No. 34187/62. Headings B8E and B8S. A bunker conveyer 16 disposed between an endless feed conveyer 12 and an endless main conveyer 14 comprises an open-topped elongated bunker 20 having a front discharge opening 32, a lower endless open scraper conveyer 18 the upper run of which moves along the floor 22 of the bunker towards the opening 32, an upper endless open scraper conveyer 46 disposed above the conveyer 18 and having its lower run moving towards the opening 32, and a plurality of inverted V-section plate members 48 located between the two scraper conveyers and mounted on transverse pivots 54, the rearmost member defining a material access opening with the rear wall 28 of the bunker. In the bunker conveyer rest condition, the front lower edge 56 of one plate member 48 extends below the rear lower edge 58 of the adjacent member 48, the rear of each member 48 being restrained from tilting downwardly by stop members 60 secured to the side walls of the bunker. In operation, material delivered by the conveyer 12 drops through the moving scraper conveyer 46 on to the bunker floor 22, where it is scraped forwardly to an aperture 31 in the floor and discharged through the lower run of the scraper conveyer 18 on to the main conveyer 14. If the delivery rate of the conveyer 12 exceeds the lower scraper conveyer capacity, the material heaps up at the rear of the bunker and upon reaching the level of the lower run of the upper scraper conveyer 46, is moved forwardly and accumulates on top of the plate members 48. The loading of the material on the rear plates 52 of these members 48 prevents the front plates 50 from tilting down. A switch 72 is provided on a front wall 42, to stop the feed conveyer 12 if the material accumulates up to this wall and is scraped over the top to drop on to a hinged lever 70. Due to the latter condition or due to an underloaded feeding conveyer 12, the bunkered material first slides from the rear plate 52 of the rearmost member 48 whereupon the member 48 tilts forwardly to release the material thereabove and so on. The desired height of material being conveyed on the lower scraper conveyer is such that it lifts any tilted members 48, back to their rest condition. A further switch may be associated with the rear member 48 to restart the feeding conveyer 12 as soon as this member 48 commences to tilt. In a modification the members 48 take the form of buckets.
