Title: A new or improved scraper for use in cleaning cattle wagons, or for like purposes
IPC: B60S3/00
Filed: 1928-07-10
Abstract: 320,130. Dixon, W. G., and Railway Supplies Co., Ltd. July 10, 1928. Scrapers. - A scraper for cleaning cattle wagons has a scraping edge with a notch of proper size to straddle a floor batten so as to scrape the sides of the batten and the angles between the batten edges and the floor. The scraper blade 1, which may be curved, is ground and sharpened along all the edges of the notched side 3 and along the opposite side 4, the remaining sides being reentrant and sharpened near the corners. The blade is secured to the stem 2 of a D or T-shaped handle 6 by means of a V-shaped yoke 8 riveted at 10 to the stem 2 and having its loop end 9 extending beyond the end of the handle stem through a rectagular hole 7 in the blade. A curved spring strip 11 passed between the yoke end 9 and the blade 1 holds the blade resiliently against the forward end of the handle stem and is secured in position by a screw 12 passing through registering holes in the yoke end 9 and spring strip 11.

Title: Improvements in or relating to air-conditioning systems in motor vehicles
IPC: B60S1/64
Filed: 1936-07-20
Abstract: 461,603. Ventilating vehicles. METZGER, K. July 20, 1936, No. 20097. [Class 137] [Also in Group XXVI] A motor vehicle is provided with an air conditioning system in which the direction of the air flow may be reversed and the air pump used either for withdrawing air from the interior or for operating a vacuum cleaning device. A centrifugal air fan 1 is driven by an electric motor 2, which may be the electric generator driven from the engine by a pulley 3, and the direction of the air flow is controlled by valves 11, 12 operated by a control 16 from the dash-board. The air may be forced through the conditioning units 20, 21, 22 for cooling, moistening, cleaning, ozonizing or the like before discharge into the vehicle through a conduit 18. Alternatively, the air may be withdrawn from the car through a conduit 17. A dust bag 51 in a casing 50 may be connected to the tube 17 when a vacuum cleaning tube 37 with the usual attachments is inserted into the conduit 18, after taking off the tray 38 which is used as an ash tray, when air is withdrawn from the interior. A sieve 36 may be provided in the tube 18. A two-stage centrifugal fan is formed with a casing of cup-shaped members 23, 24 between which is secured a member 28 from which is supported a ball bearing 30 in which one end of a shaft 26 rotates. Secured to the shaft are two fans 27, 32, the former drawing air from an inlet 34 and the latter forcing the air into a duct 33. The air fan or pump may be used for pumping water, or for spraying the car for cleaning purposes, or for pumping up the tyres. The air heating means may be a coiled tube located near the heated parts of the engine and filled with steel chips.

Title: Method for the manufacture of therapeutic preparations liberating carbonic acid
Filed: 1935-07-15
Abstract: In therapeutic substances comprising ingredients which under the action of water interact to evolve carbon dioxide, these ingredients are coated separately with a fatty substance, e.g. cocoa butter to which lecithin is added or in which it is present in substantial amount, the effect of the lecithin being to accelerate the reaction.ALSO:In the preparation of therapeutic substances comprising ingredients which interact to evolve carbon dioxide, the said ingredients are separately coated with greasy substances, e.g. cocoa butter to which lecithin is added whereby the evolution of gas is prevented until the mixture is brought into contact with an aqueous agent, whereupon the lecithin being of hydrophile nature assists the reaction.  Naturally occurring substances containing lecithin may also be employed.
Patent GB-340573-A (GB)
Title: A process of treating rubber and products obtained thereby
IPC: C08K5/00
Filed: 1929-07-01
Abstract: The vulcanization of rubber is accelerated without danger of scorching, by the use in the presence of a metallic oxide such as zinc oxide, of a compound including the group <FORM:0340573/V/1> in which R represents N, O, or C, and X represents O or S, for example dithiocarbamates, xanthogenates, and dithiobenzoates, (R and X may also be members of a thiazole ring), and Y represents carbon in a substituted cyclic or methyl group that does not contain O or S doubly bonded to Y, the compound being characterized by the fact that it hydrolyses at the SY bond in aqueous alcohol in the presence of sodium hydroxide at least as rapidly as diphenylmethyl dimethyl dithiocarbamate.  The preparation of these substances is described in Specification 340,574, [Group IV].  Numerous examples of such compounds are specified including polynitro aryl esters of substituted dithiocarbamic acid having at least one nitro group ortho to the 1 position, and one of the remaining groups meta to the nitro group, and phenyl methylene bis esters of alkyl dithiocarbamates. The rate of acceleration is increased by the addition of inorganic basic materials such as ammonia, and it may be retarded by the use of acids.  These substances may be introduced into the rubber by diffusion, for example, by vulcanizing in a closed container in an atmosphere of ammonia, under heat and pressure which may be augmented by the introduction of air, or by painting, dipping &c. the articles before vulcanization.  Many examples of suitable mixes, processes &c. are given.
Patent GB-816929-A (GB)
Title: Process for shredding and pre-ripening alkali cellulose
IPC: C08B1/08
Filed: 1956-06-29
Abstract: In a process for shredding and pre-ripening alkali cellulose, the alkali cellulose coming from the immersion press is shredded for 50-70 minutes at 30-35 DEG  C. in a shredder, immediately cooled, if desired in vacuo, to 15-25 DEG  C., and is then shredded during pre-ripening for at least 10 hours at this temperature. Preripening may be completed after cessation of the shredding either with the alkali cellulose stationary or with further movement of the alkali cellulose.  A strengthening of the mechanical effect on the alkali cellulose may be obtained by increasing the speed of revolution of the shredding knife and, for the same purpose, abrasives, e.g. titanium dioxide, may be added to the alkali cellulose during shredding.  The first shredding temperature may be obtained without supply of heat by using the frictional energy and heat of reaction. When the pre-ripening has proceeded to the desired extent, after-ripening may be carried out.  By the process the pre-ripening time is shortened and a lower initial sulphidizing temperature may be employed.

Filed: 1937-07-27
Abstract: In the production of spinels by fusing mixtures of zinc oxide and titanium dioxide by the Verneuil process, the mixtures, which contain 0,9-2 mols. ZnO per mol. TiO2, are preheated to temperatures between 500 and 1000 DEG  C. and then fused, whereby loss of zinc oxide by volatilization is minimized.  Instead of the oxides, compounds which yield the oxides when heated, such as titanium dioxide hydrate or zinc carbonate, may be used.

In the illustrated embodiment the wheel cleaner comprises horizontal rollers 10 on which the wheels of a vehicle can be spun to throw off dirt by centrifugal action. The frame 11 is provided with recesses 16 inside members 15 thereof in which the ends of a weigh beam 17 extending transversely of the frame are located. Each end of the beam 17 is connected through a bearing assembly 22, which permits tipping or tilting of the beam to a bolt 23 having a nut 24 locked to it which bears on a load cell 25 supported on a member 27 bridging the associated recess 16 of the frame. The load cells 25 are in the form of electrical transducers which are connected in a circuit, Fig. 5, capable of summing the signals from the cells at the two ends of the beam to give individual axle weights of a vehicle, storing and summing the individual axle weights to give total weight of the vehicle, and subtracting the tare weight from the total weight to give the pay load of the vehicle, the circuit being connected to means which provide a visual display and/or print out of  the information obtained. At each side of the frame 11, vertical movement of the beam 17 is limited by abutment of the associated end of the beam with blocks 38 on the frame, and movement of the beam in its longitudinal direction is restrained by contact of an abutment on a bracket 34 at the associated end of the beam with the outer cases of needle roller bearings 36 on a shaft 37 mounted in the blocks 38. The apparatus may be provided with alarms to warn if individual axle weights are in excess of a predetermined limit and to warn if a vehicle is driven too fast over the frame for accurate weighing.
