Abstract: 1,107,163. Spray carburetters. SOCIETE INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. June 6, 1966 [June 15, 1965], No.25152/66. Heading F1B. In a constant suction type carburetter wherein the fuel is fed to chamber 10, Fig. 4 and sucked therefrom, mixed with air, by a pump 5 which delivers through passages 7 to the individual intake pipes, accelerating fuel is delivered through a pipe 21, Fig. 3, connected to an orifice 28 arranged downstream of the main fuel orifice 27. The orifices 27, 28 are arranged in a block 26 projecting into the intake pipe 1 and they open into a common passage 29 containing a restriction 30. The main fuel flows past the bevelled end of orifice 28 and assists in atomizing the acceleration fuel. In Fig. 1 (not shown) the accelerating fuel is fed by the main feed pump (P) to an accumulator (25) from which the fuel is injected during acceleration when a suction controlled valve (24) opens.

Title: Improvements in or relating to the manufacture of resilient rollers
Inventor: JOHNSON PHILIP COWEY
IPC: B29C39/10
Filed: 1957-08-09
Abstract: A process for the manufacture of resilient rollers by coating a central shaft with polyurethane is characterized in that the polyurethane is prepared from a linear polyester and a polyisocyanate having more than two isocyanate groups in the molecule in the absence of formaldehyde, formaldehyde-liberating substances and polyvinyl acetals.  The polyesters suitable have a molecular weight of 500-5,000.  They can be prepared from succinic, glutaric, adipic, alkyladipic, pimelic, suberic, beta-ethyl-suberic, azelaic and sebacic acids, and ethylene, propylene, butylene, diethylene, triethylene, tetramethylene, hexamethylene and decamethylene glycols. Examples of suitable polyisocyanates are toluene-2 : 4 : 6-triisocyanate, 2 : 4 : 41-triisocyanatodiphenyl ether, polymeric polyisocyanates obtained by heating tolylene diisocyanate in the presence of sodium methoxide and reaction products of tolylene diisocyanates with glycerol or trimethylol propane.  To the polyurethane forming mix may be added catalysts such as dimethyl cyclohexylamine or bis (diethylaminoethyl) adipate, antifoaming agents, plasticizers and colouring agents.  In Examples (1) a linear polyester from diethylene glycol and adipic acid is reacted under reduced pressure at 70 DEG C. with toluene-2 : 4 : 6-triisocyanate. The mixture is poured into a cylindrical mould containing a centrally placed metal rod and the mixture is heated at 110 DEG C. to effect curing; (2) a polymerized mixture of 2 : 4- and 2 : 6-tolylene diisocyanates is used as the polyisocyanate.

Title: Improvements in or relating to the stretching of leather
IPC: C14B1/02
Filed: 1945-10-12
Abstract: 606,523. Stretching leather. BECK, F. Oct. 12, 1945, No. 25579. [Class 76] Leather or skin for use in the manufacture of gloves by the table cutting process is stretched by passing backwards and forwards under tension over a heated edge or bar. The leather is preferably threaded between the heated edge 13 and a bar 17, mounted on levers 15 pivoted at 16, and held in operative position by a spring-loaded hand lever 23. The edge 13 is formed at one side of a curved table 12 which is heated by an electric heater 25 to about 60‹C.; an electric heater 35 may also be provided in the bar 17, and the bar may be covered with textile material to polish the leather. The leather is pulled through the device by hand and may be returned by means of a spring or weight attached to the end lying over the table. In a modification of the apparatus, Fig. 3 (not shown), the bar 17 is replaced by a mechanically driven rotating roller, and in a further modification the bar is fixed instead of being movable. The Provisional Specification describes also the provision of power-operated reciprocating means or a hand-operated lever for attachment to one end of the piece of leather, the arrangement of two or more pieces of leather to be pulled through the device in a pile, the use of the device without any heating means, the combination of the device with slitting or cutting means to cut the outline of a glove from the stretched leather, and the application of the device to the stretching of leather for other purposes.

Title: Method of and apparatus for continuously testing the concentration of a constituent present in a liquid
IPC: G01N21/78
Filed: 1951-11-02
Abstract: 721,884. Photo-electric control of water softening plant. MARSHALL, A. T., and BRITISH ELECTRICITY AUTHORITY. Feb. 2, 1953 [Nov. 2, 1951], No. 25632/51. Class 40 (3). In apparatus for testing a constituent of a liquid such as the hardness of water constant stream of the liquid under test is mixed with further constant streams of a reacting liquid and an indicator liquid the resulting mixture being passed through a chamber where it is heated photo-electrically, a warning being operated if the indicator changes colour. The invention is described with reference to testing the hardness of water by mixing it with a reagent consisting of a solution of the disodium salt of ethylene diamine-tetra acetic acid, an indicator comprising a solution of erichrome black T, and a borax buffer solution to adjust the pH value of the mixture. As shown, the water under test enters a chamber 9 and flows through an aperture 14 into a second chamber 5, leaving an orifice 10 in the bottom of the second chamber. The rate of feed is such that water escapes continuously through an orifice 15, thus ensuring a constant head over orifice 10. The three solutions referred to above are supplied to chambers 2, 3 and 4 from constant head devices comprising reservoirs 18 into which an air inlet tube 19 depends. Thus the level in chambers 2, 3, 4 does not rise above that at the bottom of the tube. The rate of flow of the liquids is adjusted by means of rods 11, the tapered ends of which restrict the flow through the orifices. Collars 12 enable the position of the rods to be adjusted. All the liquids fall into funnel 22 and enter through a cylindrical chamber provided with transparent end-plates 26. A beam of light from source 29 passes through the plates to a red-sensitive photo-cell 30. One or both of these plates is coloured red so that if the indicator remains blue no light reaches the photo-cell. If the indicator turns red the cell operates through amplifier 31 to switch off a green lamp 32, switch on a red lamp 33 and operate a warning device 34. It may also shut down the water softening plant.

Abstract: 463,728. Wearing-apparel. RAVEN, R. F., and RAYNOR, H. A. Sept. 17, 1935, No. 25753. [Class 141] [Also in Group VIII] A garment or fabric incorporates courses of elastic thread and alternating or interspersed courses of inelastic thread, but, over a group of wales less than the whole, has one kind of thread knitted into spaced wales only. A seamless tubular corset has, at top and bottom, a band of fabric having good circumferential (coursewise) stretch, but little stretch in the direction of the wales, by causing only spaced selected needles (e.g. the dial needles) to take and knit an elastic thread 13 whilst all needles take and knit inelastic threads 11, 12, 14. Between these two bands is a front panel in which the stretch is restricted in both directions by causing only spaced selected needles (e.g. the dial needles). to knit the inelastic thread 12, and the elastic thread 13 whilst all needles knit the inelastic threads 11 and 14. A rear panel is elastic in both directions, since all threads are knitted by all needles. An elastic weft thread 15 is laid in by a further feeder. The circumference of the garment may be controlled by varying the tension on this thread 15, which is thicker than the elastic thread 13. The elastic threads may be wrapped or covered. The inelastic threads may be of different kinds. The needle cylinder is provided with short needles 19 working in an upper cam race, in that part which produces the front panel, whilst in the part on which the rear panel is produced, there are long needles 20, working in a lower cam race. Upper and lower clearing cams are provided at each feeder except that feeding elastic thread 13, where there is a lower clearing cam only. This lower cam, and the upper cam at the feeder for thread 12 are adjustable downwards to inoperative positions as required. Suitable selecting mechanism may be used to produce the same effect. Both elastic and inelastic threads may be knitted into spaced wales only. Both dial and cylinder ' needles may be made to miss at the predetermined feeder or feeders. The fabric may contain tuck stitches. In a part wherein either or both of the threads is knitted into spaced wales of a group, the needles of that group may be made to remain inactive for spaced courses, whilst the other needles knit these courses ; or, in a multi-feeder machine, the needles of the group may miss the thread at one or more feeders.
