Title: Improvements in and relating to vacuum cleaners
IPC: A47L9/19
Filed: 1935-09-26
Abstract: 441,678. Suction cleaners. BRITISH THOMSON -HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 26, 1935, No. 26654. Convention date, Sept. 27, 1934. [Classes 8 (i) and 8 (ii)] In suction cleaners in which an electric motor creates a suction at a nozzle and in which a bag for receiving the dirt drawn through the nozzle is supported from a handle, a switch connected to the supporting means operates a signal-device when the bag contains a predetermined weight of dirt. The bag (not shown), is supported by the hook 13 from the spring-controlled bolt 15 working in guides in the casing 16 mounted in the handle 5. When a predetermined amount of dirt has collected in the bag, the contacts 20, 21 close and the lamp 22 is lit to indicate that the bag requires emptying. Should this signal be disregarded, the spring finger 41, finally mounts the knuckle 45 and contacts with the insulator 44. The current for the motor is then cut off.

Patent GB-269927-A (GB)
Abstract: 269,927. Soc. des Produits Chimiques de Clamecy. April 22, 1926, [Convention date]. Alcoholic liquids, distilling.-In a process for distilling pyrolignious acid by separating the constituents in two portions containing respectively (1) methyl alcohol, methyl acetate and acetone, (2) pyroginated impurities. e.g. allyl alcohol and acetic acid, the pyrogenated impurities are used to concentrate the acetic acid fraction. The apparatus comprises a number of stills A from which the methyl alcohol vapours pass through pipes 1 to a column B where they are treated with benzene from a decanter E. The vapours of the binary mixture formed are condensed in a condenser C and the distillate is treated with water from a pipe 4 in a column D. The resultant mixture is separated in the decanter E, the methyl alcohol passing off through a pipe 5 while the benzene is returned to the column B. When the methyl alcohol vapours have been driven off the pipes 1 are closed and the next fraction is led through pipes 6 to a column F. The vapours are condensed in a cooler G and treated with water in a column H, the resultant mixture separating out in the decanter I into two layers comprising a light oil layer, and an aqueous layer containing a small percentage of acetic acid which is separated off through a pipe 10. The oily layer containing allyl alcohol is returned to the column F where it causes condensation of the acetic acid which is led through a pipe 11 to a still J.

Disc-tool implements; lifting tool frames manually; reversing at headlands.-In reversible disc ploughs wherein the disc is mounted on a longitudinal shaft, means are provided whereby the driver can reverse the disc by an operating lever moving in a vertical plane longitudinally disposed in relation to the plough. A ploughing disc E is carried on a cranked spindle F on a yoked bearing G which is fitted on a rod II carried in extensions C<1> of a frame C. By means of mechanism K, L, J, G<1> the disc can be lowered to the required working level. A transverse arm N is fixed to the spindle F and connected by a transverse link O to the end of an operating lever P pivoted about a bracket Q. On depressing the end P<1> of the lever P, the link O is moved up and the disc-carrying spindle F is partially rotated. When the end' P<1> is in the lowest position the disc has moved past the vertical, so that it moves into its second working position when the lever P is released. Two such discs may be fitted to one spindle. The end P<1> may be bent to facilitate the operation of the lever P as a foot-operated lever.

Abstract: 538,353. Hydrocarbons. GAS LIGHT & COKE CO., and GRIFFITH, R. H. Jan. 27, 1940, Nos. 27437/39 and 135/41. [Class 2 (iii.)] Olefines are obtained by treating an aldehyde or ketone at raised temperature with hydrogen in an amount in excess of that theoretically necessary for the production of the olefine, in the presence of a de-oxygenating catalyst consisting of a compound, e.g. an oxide or sulphide, of vanadium, tungsten, or molybdenum. Temperatures of 300‹ to 500‹C. are employed, and the conditions are preferably such that some of the aldehyde or ketone remains unchanged. The catalyst may be employed in powdered form or as granules or deposited on a carrier, e.g. alumina. In examples the following compounds are hydrogenated in the presence of a molybdenum oxide catalyst: (1) dipropyl ketone, to yield a mixture of heptenes, together with some heptanol-4, n-heptane and methylhexane, (2) acetophenone to yield styrene, (3) butyric aldehyde to yield normal butylene, (4) mesityl oxide to yield 4-methylpentadiene-1 : 3, and (5) crotonaldehyde to yield butadiene 1:2.

Title: Improvements in the production of photographic colour picture films having a sound record
IPC: G03C7/24
Filed: 1936-10-09
Abstract: 483,271. Kinematograph colour picture films bearing sound records. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Oct. 9, 1936, No. 27452. [Class 98 (ii)] In the production of subtractive colour pictures and a sound record on material having several emulsion layers containing dyestuffs or dyestuff components on one or both sides of a support, the latent sound and picture images are developed to silver, and the silver sound record is converted to a chemical compound which is equivalent to silver for scanning purposes and is indifferent to the baths which are subsequently applied to process the picture images to colour by the silver bleaching-out dye process. The sound record may be formed in one or more emulsion layers. In one example, the silver sound record is treated with a bath containing potassium ferricyanide, potassium bichromate, iron ammonia alum, and oxalic acid applied by local immersion or by rollers &c., thereby producing a Prussian Blue sound image. In another example, it is first treated in a bath containing lead nitrate, ferricyahide, and nitric acid, cleared in dilute nitric acid and washed, and then treated with a bath containing cobalt nitrate, potassium bromide, and nitric acid. After thus converting the sound record, the colouring matters initially present in the film, and particularly the blue-green, may be destroyed in known manner in the region of the sound track when the pictures are processed by the silver bleaching out dye process either by diffuse illumination before immersion in the bleaching bath for producing the colour images, or by a separate bath which itself destroys the colour, e.g. when the blue-green dyestuff is Brilliant Benzo Fast Green, it may be destroyed along the soundrecord area by local application of a bath containing potassium bichromate and sulphuric acid.

Abstract: 1294510 Moulding grommets SHRINK TUBE & PLASTIC Ltd 3 June 1971 [8 June 1970] 27604/70 Heading B5A [Also in Divisions F2 and H2] A grommet for locating a cable, wire, pipe, or pin passing through a hole 9 in a panel 10 comprises a tubular portion 1 for location in the hole with a shoulder 4 abutting one side of the panel the tubular portion being deformable when heated to produce a second shoulder which abuts the other side of the panel, and a sleeve portion 5 integral with the tubular portion 1 having a bore 6 which is contracted by heating to grip the cable, wire, pipe, or pin 11. The grommet is formed in the shape shown in Fig. 2 by dip moulding or injection moulding, from a material which can be reformed by heating to a second shape, which is maintained after cooling, and is self-deformable by further heating to return to its first shape. Plastics such as cross-linked or normal P.V.C., cross-linked polyethylene, chlorinated polyethylene either cross-linked or not, neoprene, ethylene propylene rubber, silicone, and fluorinated silicone are suitable. After moulding, the grommet is reformed by heating in a moulding tool to the shape shown in Fig. 1. On installation, the grommet is heated, and returns to the Fig. 2 shape. The sleeve portion 5 may be internally coated with a hot melt adhesive which bonds to the cable 11 at installation. A silicone rubber sleeve or band may be placed around the tubular portion 1 so that on installation it is pressed against the panel for sealing. The tubular portion may have an internal annular groove 7 which houses an expansible coil spring 8 to assist in forming the second shoulder on heating during installation. In this case a rigid collar is placed round the tubular member at the plane of the spring 8 after the reforming, to prevent expansion during storage.
