Title: Improvements relating to vehicles for refuse collecting and like purposes
IPC: B65F3/08
Filed: 1945-11-23
Abstract: 602,569. Loading vehicles load-handling machines. NASH, A. G. FRAZER-. Nov. 23, 1945, No. 31660. [Classes 78 (iii) and 78 (iv)] In means for loading loose materials into a vehicle a carrier for a dustbin or similar container is mounted between vertical guides along which it is moved by traversing mechanism connected to the carrier by a flexible connector 29 engaging with the profile of a tension transmitting member 30 on the carrier, stops being provided to arrest the motion when the carrier reaches the upper ends of the guides, whereupon during continued operation of the traversing mechanism the flexible connector, while progressively disengaging itself from the profile of the transmitting member, causes the carrier together with the dustbin to be tipped. In an arrangement for two dustbins to be emptied simultaneously, the dustbin 12 is supported by a carrier 13, 14, 15 with hooks 16 or spring- loaded catches for engaging the handles 17. The carrier is raised by trunnions 22 running in guides 21 as a pair of arms 23 pivotally mounted in brackets on each side of the filling opening are rotated by a jack 26. A rod 28 and chain 29 connects each arm 23 with pulley guides 30 mounted eccentrically with respect to the trunnions. Continued operation of the jacks when the carrier reaches the top of the guides causes tipping initiated by rollers 33 mounting a ramp on the vehicle, the movement being progressively accelerated. The filling opening has a shutter hinged to'a plate hinged to the vehicle, the shutter closing an aperture in the plate. A projection on the dustbin lid engages a recess in the hinged shutter and as the dustbin is inverted the plate is swung downwards and the shutter upwards with the lid. To ensure completely emptying the dustbin, it is shaken by means of springs interposed between arms @23 and rods 28 and buffers on the vehicle body which when engaged by the shutter plate or rim of the dustbin load and under the slow action of the jack gives a shaking movement to the dustbin. For returning the dustbin to its initial position an arm or bracket projecting from the plate is secured to the upper end of a return spring secured to the body so that on the return stroke of the jack, the plate will become vertical and the dustbin returns to its original position. The loading unit may be made as a separate unit mounted on a trolley.

Abstract: 394,668. Moulding abrasive and refractory articles. CARBORUNDUM CO., Ltd., Trafford Park Road, Manchester. -(Carborundum Co. ; Niagara Falls, New York, U.S.A.) Dec. 28, 1931, No. 31690/32. Divided on 394,667. [Class 87 (ii).] Moulded refractory and abrasive articles are. made by jolting in a mould a mix containing a granular material and a bond, removing excess mix from the mould, e.g. by striking off the upper surface, and applying a consolidating pressure to the mix remaining in the mould. The jolting may be continued during the final consolidation which may be carried out so that a predetermined volume of the mix in the mould is consolidated to a predetermined volume, e.g. by means of a stop mould. By controlling the direction of the jolting the orientation of the particles of the granular materials, which are usually of irregular dimensions, may be controlled, e.g. by jolting the mix in a vertical direction only the particles may be orientated so as to lie horizontally. Abrasive wheels may be made in the apparatus shown which includes a mould held centred on a table 10 by springs 15 and comprising a. body ring 3, a strike-off ring 4, a base plate 5 and a central post 6 for forming the arbor hole in the wheel. The table 10 has a plungerlike support 11 fitting in the top of an air cylinder 12 and normally resting on shoulders 14; the mould may be vibrated vertically by alternately admitting air pressure to the cylinder 12 and releasing the pressure. The mould may be vibrated in a number of horizontal directions by pneumatically operated hammers 16 .. 19, each guided by pins 20 and having a plunger 21 sliding in the end of an air cylinder 22 to which pulsations of air are applied. A follower plate 43 guided by a post 6<1> projecting from the post 6 may be provided for a preliminary consolidation of the material.

Abstract: 399,663. Searchlight reflectors. FERRERO, M., 3, Via Baldassare Peruzzi, and SALANI, E., 109, Corso Trieste, both in Rome. Nov. 15, 1932, No. 32333. [Class 75 (ii).] The reflecting surface of a searchlight is formed by bending a single metal foil or strip, or a plurality of foils or strips, against a suitably shaped support or supports, and means are provided to adjust the strip or strips on to the support or supports. In the form shown in the Figure, a cylindrical reflector of parabolic outline is formed by pressing a rectangular metal sheet 2 against a series of adjoining supports 1, the edges of the sheet 2 being held in the channels 3<1>, 3<11>. The channel 3<11> is adjustable by means of screws 4 secured to brackets 5 on the outer edge of each of the supports 1. The brackets 5 are elastic so as to allow movements of the sheet 1 due to thermal effects. To reduce such movements, the sheet and supports have approximately the same coefficient of thermal dilatation. The searchlight is mounted on a carriage mounted on wheels running in a circular path about a central vertical pivot. When the reflecting surface is a surface of revolution such as a paraboloid, it is formed by a number of strips of approximately triangular cross section, with their vertices abutting at the vertex of the paraboloid, and held in position at the other end in a manner similar to that described above.

Filed: 1948-12-14
Abstract: 652,784. Glass blowing moulds. DOW CORNING CORPORATION. Dec. 14. 1948. No. 32368. Convention date. Feb. 16. [Class 56] A mould for blowing glass bulbs comprises a metal mould having on its glass contacting surface an adherent coating comprising a copolymer of one or more monomethyl silsequioxanes and/or monophenyl silsesquioxanes with dimethyl siloxane or methylphenol siloxane, the diorgany siloxane units amounting to 5-90 per cent of the total siloxane units. The mono and di-substituted organo siloxanes may be prepared by the hydrolysis of the corresponding mono and di-substituted chlorosilanes RSiCl 3 , R 2 SiC1 2 , and subsequent condensation or dehydration of the resulting hydrolysis products carried to the point that the siloxane is soluble in such solvents as toluene. When the mono and di-substituted starting materials are mixed and the mixture hydrolized and condensed, copolymerization takes place, and using 5-90 mol. per cent of the di-substituted material given above and 95-10 mol. per cent of the mono substituted material the resultant copolymer is not brittle and is particularly resistant to decomposition at high temperatures. The copolymer may be dissolved in toluene &c. and applied to the metal mould which has been cleaned and pickled with a metallic phosphate rust preventative, and heated at 200-300‹C. In use the coating becomes covered with a thin porous siliceous residue which is wear-resistant and absorbs sufficient water to provide the necessary steam cushion for the glass article being formed. Fillers such as finely divided carbon, silica, or titanium oxide may be added up to 50 per cent by weight of the finished coating. Curing catalysts such as paint driers, e.g. organic salts of cobalt, or such as alkaline materials, e.g. ethanolamines may be added to reduce the curing time or temperature. Details of the preparation, application, and performance of four examples are given. Specification 632,586, [Group V], is referred to.
