Title: Improvements in and relating to bin-lifting gear for refuse collecting vehicles
IPC: B65F1/16
Filed: 1964-06-06
Abstract: Bin lifting and discharging gear attached to the rear apron 1 of a refuse collecting vehicle comprises a swingable bin lifting and gripping assembly 2 for a large capacity bin 3. A U. shaped lifting frame 9 with two cantilever arms 9a with rollers 10 is raised by an hydraulic ram 14, 15, Fig. 1 (not shown), to engage flanges 21 at each side 211 of the bin 3 to lift it from the ground (whereon it runs down the rollers 10 to engage buffers 12), to clamp it against a U- shaped gripping frame 4a having rubber strips 11 acting as buffers and seals. At this stage two hydraulic actuators 23, 24 pivoted at 25 to brackets 26 on the cantilever arms 9a and at 27 to a frame 28 with side panels 29 swing the assembly 2 upwards about a mainshaft 6. An upper dust shield 32 is attached to U-section rails 31 guided by rollers 30. A lower dust shield 33 consists of two panels, 33a rigidly attached to the upper dust shield 32 and 33b pivoted on hinges 34 and loaded by springs 36 mounted between points 35, 37 into a normally co-planar position with panel 33a. When arms 5 on the assembly 2 reach control arms 42 continued operation of the actuators 23, 24 rotates hinges 40 about the mainshaft 6, while the U- section rails 31 roll on the rollers 30. A spring- loaded hook 48 on the lower dust shield 33b engages a stirrup-like handle 20a on the lid 20 of the bin 3 so that as the bin is rotated into the position illustrated in Fig. 4 (not shown), the lid is opened and the contents of the bin drop into a trough 55 of a compacting device 56 of known type. If the actuators 23, 24 are single acting, restoring springs may initiate the return of the bin 3. If the actuators 23, 24 are double acting, such springs are not required.

Filed: 1964-07-10
Abstract: Fire retardant polymers are prepared by polymerizing in bulk methyl methacrylate monomer with or without a minor proportion of another copolymerizable monomer while in the form of a mixture with a vinyl chloride polymer or copolymer containing a major proportion by weight of vinyl chloride units or an after-chlorinated form of said polymer or copolymer, said mixture containing from 20 to 40% by weight of said polymer or copolymer or after-chlorinated form thereof and substantially no other polymer or copolymer. Comonomers for the methyl methacrylate include acrylic acid, methacrylic acid and esters of these acids, acrylonitrile, styrene and substituted styrenes, e.g. halo-styrenes. The vinyl chloride copolymer may comprise units of vinyl acetate, vinylidene chloride, ethyl acrylate or acrylonitrile. Polymerization may be initiated by heat or light preferably in the presence of a catalyst such as a ,a 1-azodiisobutyronitrile, benzoyl peroxide or lauroyl peroxide for heat polymerization, or benzoin, acetoin, butyroin or diacetyl for light activated polymerization. A known flame retardant agent may be included in the polymerization mixture, e.g. a phosphate ester such as trischlorethyl phosphate or trisdibromopropyl phosphate, a chlorinated paraffin, or one sold under the Registered Trade Mark " Phosgard." Other optional additives include dyestuffs, U.V. absorbers, heat stabilizers and plasticizers exemplified are dibutyl tin dilaurate and 2,4 - dihydroxy - benzophenone.

Title: Method of manufacturing printed circuits having metallised holes
IPC: C23C18/16
Filed: 1968-01-18
Abstract: A printed circuit board is provided with metalized through holes by coating the printed conductors and substrate with an electrically conductive layer and then an electrically insulating film, piercing the holes through the substrate, metalizing the walls of the holes by electrolysis, and removing the film and conductive layer. In a first example a copper, paper laminated sheet is silk screened with a resist and etched to form the printed conductors on both sides, after which the two faces of the sheet are covered by a thin aluminium layer by evaporation. The sheet is then dipped in glycerolphthalate, dried and immersed in a solution of aluminium stearite in toluene. After drying, the holes are pierced and the sheet seeded by a solution of palladium chloride and hydrochloric acid and a solution of stannous chloride in hydrochloric acid. Copper is then electroless deposited by dipping in a solution of sodium-potassium-tartrate, sodium hydroxide, copper sulphate, ethylene diamine tetra acetic acid and formaldehyde. A further layer of copper is then deposited electrolytically the aluminium coating providing an electrical connection between a contact and the copper in the holes. The lacquer is removed by dipping in trichloroethylene and finally the aluminium is dissolved in a sodium solution. In a second embodiment a copper clad epoxy resin reinforced by glass fibre sheet is photo-etched to produce a printed circuit pattern after which a thin copper layer is deposited over the sheet by a seeding and electroless deposition process followed by a silicon lacquer film. The sheet is then pierced and the walls of the holes coated with copper as in the first embodiment, the thin copper layer acting as an electrode instead of the aluminium. The silicon lacquer film is then removed by brushing and the thin copper layer dissolved by ferric chloride from the face carrying the printed circuit pattern. Nickel is then electroplated on to the exposed pattern and holes by supplying current to the thin copper layer on the opposite face which copper layer and covering of lacquer are finally removed by dissolving and brushing.
