Title: Refuse collection vehicle packing head
IPC: B65F3/20
Filed: 1974-02-05
Abstract: 1402835 Refuse vehicle refuse compacting CARRIER CORP 5 Feb 1974 [2 March 1973] 05311/74 Heading B8E [Also in Division F2] A refuse vehicle having a body 4 into which refuse is fed, from a tailgate 14, and compressed against a plate 10 movable by a ram 12 has a pressure relief valve 50 which allows retraction of the plate 10 when a predetermined pressure exists in its hydraulic circuit. To avoid excessive pressure developing in the mechanism feeding the refuse from the tailgate it is necessary to reduce the predetermined pressure at which the relief valve allows movement of the plate 10 as the plate 10 moves towards the front of the body 4 and this is effected by allowing the angular position of the cylinder 12 to adjust the valve. The tailgate can be raised about hinges 16 by a ram 26 to allow the plate 10 to discharge the body 4 after the relief valve has been rendered ineffective. The valve 50, Fig. 2, comprises a body 30 and stem 32 with an inlet 34 and outlet 36 connected by ports 44 controlled by a flow controller 42 urged by a spring 46 to close the ports 44. The pressure at which the valve opens can be adjusted by moving a stem 48 to vary the spring pressure. The stem 48 is forced inwards by the movement of the ram 12 as the plate 10 moves rearwards in the body 4 and vice versa.

Abstract: 386,462. Wrapping-machines. PACKAGE MACHINERY CO., 132, Birnie Avenue, Springfield, Massachusetts, U.S.A. Feb. 24, 1932, No. 5499. Convention date, July 8, 1931. [Class 94 (i).] Relates to machines for wrapping articles in a material having a soluble coating, e.g. the material known by the registered Trade Mark of " Cellophane " with a coating comprising a nitrocellulose and a wax. The coating is soluble in acetone or ethylene glycol mono-methyl ether. As shown, an article a, Fig. 1, is raised by a plunger 15 between guides 16, and carries a wrapper b with it between grippers 17, 18. A rear folder 19 turns up the corresponding depending part of the wrapper, the front flap being folded up by a plate 20 when the grippers move the article to the right. The article is fed into position a<1> by a pusher 21, and arrives between end-folding devices with the wrapper extending in rectangular tubular formation at each end. A cross-bar 23, Figs. 9 and 10, now ascends ; a plate 27 mounted thereon makes the first end fold and two side tucks, and an extension 29 of the plate presses the top part of the wrapper against a plate 32. The cross-bar continues to rise, the lost motion between it and the plate 27 being taken up by a spring 30. A bracket 25, carrying side plates 42 in the extended position shown in broken lines in Fig. 9, rises with the crossbar, and, upon reaching the upward limit of motion, the plates are released to spring inwards and to clamp the side tucks against walls 33 and against a number of wicks 37 passing through apertures in the walls. The wicks are fed with adhesive-solvent from a reservoir through a flexible pipe. During the descent of the device, the plates crease the tucks against the walls while a smear of adhesivesolvent is applied by the wicks. A transporting and folding device 22, Fig. 1, swings downwards and a part 48 thereof turns in the first tuck, and further forward movement of the device carries the article past a stationary folder 49 and turns in the second tuck. At position a<11>, an oscillating member 50, Fig. 6, swings upwards from a tank 51 of solvent and contacts with the under-surface of the upper flap g. The plate 32 and the member are formed with interfitting grooves and ridges so that no solvent is applied if a packet is absent. An oscillating carrier 52 swings the packet through a rightangle into line with a pusher 53 and shoot 54. The last flaps are folded down when the plunger forces the packet into a shoot, the first portion of which is heated and the remaining portion lined with bristles to ensure adhesion.

Title: Improved method of preparing silicones and products thereof
IPC: C08G77/00
Filed: 1943-04-09
Abstract: Low polymers of dialkyl silicones are prepared from high polymers by heating to a temperature sufficiently high to cause said composition to vaporize, and collecting the vaporous products.  The heating is preferably carried out in the absence of oxygen at temperatures of 275 DEG  C. to 300 DEG  C. or even above.  It is a subsidiary feature of the invention that a small amount of caustic alkali should be present during the distillation.  The parent materials for the invention are obtained by the condensation of a mixture of organo-silicols, comprising essentially a dialkyl silicol and a mono-organo-silicol.  In examples: (1) a mixture of methyl silicon chlorides prepared by the Grignard reaction is poured into ice water to form the corresponding silicols, which are isolated and distilled in the presence of 0.1 per cent NaOH.  The distillate is re-distilled and fractionated; (2) a copolymer composed of 60 mol. per cent of monomethyl silicon oxide and 40 mol. per cent of dimethyl silicone, is distilled at a dull red heat; (3) diethyl silicon dichloride is hydrolysed and distilled; (4) the distillate from example (3) is polymerized, oxidized, and then de-polymerized by distillation; (5) a copolymer of dimethyl silicone prepared by hydrolysing a mixture of dimethyl silicon diethoxide and ethyl ortho-silicate, is distilled at 275 DEG  C.; (6) a copolymer of monophenyl-, and dimethyl-silicon oxides is distilled; (7) highly polymerized insoluble dimethyl silicone is distilled at 400-500 DEG  C.; (8) liquid polymeric dibutyl silicone is slowly heated in air to form a copolymer of mono- and dibutyl silicon oxides which is then distilled in the presence of a small amount of caustic soda; (9) a copolymer of mono- and diamyl silicon oxides is distilled in the presence of caustic soda; (10) a dioxane solution of dibutyl diethoxy silicon and monomethyl triethoxy silicon is hydrolysed, copolymerized and then distilled.
