Filed: 1975-02-18
Abstract: 1493867 Refuse vehicle refuse compacting means SOC D'EQUIPEMENTS MANUTENTIONS ET TRANSPORTS 18 Feb 1975 [18 Feb 1974] 6743/75 Heading B8E In a refuse vehicle having an ejection plate 2 operated by a ram 3 a valve 6, not directly connected to the hydraulic circuit of the ram 3 at any time, is provided to relieve the pressure in the ram circuit when a single ramming pressure is reached. A switch 22, Fig. 2 must be closed by the discharge door being fully open to allow the ram 3 to cause ejection. When during loading a single set ramming pressure is reached the pressure in its circuit 15 will close a switch 2 causing a solenoid 17 to actuate a valve 16 to allow the circuit 6 of the ram 3 to allow the plate 2 to move back until relief of pressure in the ramming circuit 15 opens the switch 21. In order to provide a recompressing force in the ram 3 its circuit 6 may act on a switch 24 in series with the door operated switch 23 so that when pressure drops in circuit 6 the switch 24 is closed to operate a solenoid 27 to move a valve 28 to supply pressure to a distributor 7 which may be moved to supply the circuit 6. In a modification the automatic relief valve may be mechanically operated by the cylinder of the ram 3.

Title: Coated sheet material
IPC: D06M15/07
Filed: 1942-05-22
Abstract: 557,539. Coated sheets DU PONT DE NEMOURS & CO., E. I., and PETERS, F. T. May 22, 1942, No. 6984, [Class 140] A process for the production of a cellulose derivative coated sheet material having an improved bond of the coating to the sheet material and improved resistance of the coating to cracking when repeatedly flexed consists in applying to the sheet material a layer of a coating composition comprising a nylon, i.e. synthetic fibre-forming polyamide(s), methods for the production of which are described in Specifications 461,236 and 461,237, [both in Group IV], and applying directly over the nylon coating a cellulose derivative composition. The base material may be woven cotton fabric but others are suitable such as unwoven cotton fabrics, regenerated cellulose, paper, woven and unwoven glass fabrics, fabrics made from cellulose derivative yarns such as viscose and cellulose acetate, leather and nylon fabrics. The cellulose derivative coating may be cellulose nitrate or other esters such as cellulose acetate, cellulose propionate and cellulose butyrate or ethers such as ethyl cellulose and benzyl cellulose or mixed esters and ether esters such as cellulose acetopropionate and cellulose acetobutyrate. The polyamides for the anchor coating may be derived solely from the polyamide-forming reactants but may include also condensation products obtained by including with the polyamide forming reactants other condensation product forming compositions, e.g. hydroxy acids, glycol-dibasic acid mixtures and amino alcohol-dibasic acid mixtures. Interpolyamides are preferable to the simple polyamides due to their greater pliability and better solubility and one example of anchor coating is made up of nylon derived from hexamethylene diammonium adipate (85 per cent.) and 15 per cent. of an equimolecular mixture of ethylene glycol and adipic acid dissolved in a solvent mixture of toluene and alcohol, a coating of a cellulose nitrate composition being then applied over the anchor coat. In another example the nylon was derived from hexamethylene diammonium adipate. hexamethylene diammonium sebacate and caprolactan. Other interpolyamides and melt blends of two or more preformed polyamides are mentioned. The amount of dry nylon coating useful in achieving the objects of the invention is between 0.4 and 1.5 ounces per square yard of sheet material.

Title: Improvements in methods of and means for transmission by electro magnetic waves of television signals and the like
IPC: H04N3/00
Filed: 1932-03-09
Abstract: 403,395. Television. WALTON, G. W., 2, Dean Street, Soho, London. March 9, 1932, No. 7112. [Classes 40 (iii) and 40 (v),] The object is resolved into elemental images, each of uniform brightness in at least one direction and together representative of the whole of the object, and electric pulses of the same wave length or of periodically varying wave length are derived, each representative of the difference in brightness between two of the elemental images or between one and a fixed datum. Transmitter.-An image of the object to be transmitted is split into narrow parallel bands by a device 1, Fig. 2, comprising transparent plates cemented together. Owing to internal reflection there is even luminosity across each band in the direction 5, 6 when the light emerges from the device 1. According to a modification the device 1 comprises alternate opaque and transparent bands a short distance behind the image Fig. 4 (not shown The image is transformed into a continuous one-dimensional image 8, in a direction at right angles to the plates 1, by an echelon device 7, as described in Specification 328,286, [Class 40 (iii), Telegraphs, Electric], and oscillated across an aperture in front of a photo-electric cell by a vibrating mirror, Fig. 5 (not shown). Alternatively the image, is scanned by an ordinary mirror wheel, Fig. 6 (not shown). The light falling on the aperture follows an intensity curve of the type shown in Fig. 8. The aperture, Fig. 7 (not shown), in front of the cell is deep with a transparency along its section following a versed sine curve, Fig. 8 (not shown). The photo-electric current will thus follow a curve of the type shown in Fig. 10, in which the sharp rises and falls of Fig. 9 have been converted to curves always of the same trigonmometric shape but of varying slope. If this current is passed to an aerial through an amplifier of the type described in Specification 375,831, ether waves are transmitted of the type shown in Fig. 11, which is a first differential of Fig. 10 and comprises sine-wave impulses of differing intensity and phase, but of constant frequency. Alternatively these impulses, tnadulate a carrier wave, and one side band, Fig. 12, is selected for transmission by tuning. Receiver, Fig. 15.-The impulses are received in the primary of a transformer 45. Impulses of one phase render a thermionic valve 26 conducting to charge up a condenser 36 and impulses of the opposite phase render a valve 27 conducting to discharge the condenser. The condenser is in the grid circuit of an amplifying valve 30 and has the effect of integrating the received impulses so that the output from terminals 46 corresponds to Fig. 10. When receiving the single side band, the signals are combined with a local oscillation of the carrier frequency and detected before application to the transformer 45. Specifications 333,548, [Class 39 (i), Electric lamps, Arc &c.], and 379,552 also are referred to.
