Title: Improvements in or relating to implement hitch linkages
Inventor: DOERING CHARLES WILLIAM
IPC: A01B63/112
Filed: 1961-08-14
Abstract: 920,565. Tractor power-lift linkage mechanisms. INTERNATIONAL HARVESTER CO. Aug. 14, 1961, No. 29251/61. Class 79(1) Both the upper and lower links 23, 24 of a three point power lift linkage including automatic draft control are pivoted to the tractor so that they are capable of longitudinal movement relative to the tractor. The upper link 23 is connected to a draft-responsive member 36 biased by a spring 41 and adapted to operate the power lift in response to variations in draft load and the lower links 24 are connected to cranks 25 of a shaft 26 journalled in the tractor frame. The shaft 26 has a further crank 27 which is pivoted to a double-armed lever assembly 29 having a pin and slot connection 31, 32 with a lug on the tractor frame and a pin and recess connection 34, 35 with the member 36. With this arrangement the weight of the implement is balanced by the linkage i.e. there is no movement of member 36 due to the weight of the implement thereby allowing the member 36 to be sensitive to small differences of draft load. In modifications the draft responsive member is associated with the lower links and the lever assemblies 27a and 29 are replaced by bell-cranks.

Title: Manufacture of pimelic acid
Inventor: MAJOR FREDERICK WILLIAM
IPC: C07C51/295
Filed: 1949-11-19
Abstract: Pimelic acid is made by contacting at a pressure high enough to maintain the reactants in the liquid phase delta3-tetrahydrobenzaldehyde or its trimer or an alkaline condensation product of the monomer such as is obtained on treatment with an aqueous alkali at low temperatures, with an aqueous solution of an alkali metal hydroxide, the reaction mixture being brought to a temperature within the range 250-400 DEG  C., and the acid thereafter separated.  Under more severe reaction conditions, e.g. above about 300 DEG  C., only a small quantity of the corresponding alicyclic alcohol is formed.  The hydroxides, e.g. those of sodium and potassium alone or mixed, are preferably used in excess, e.g. a 10-80 per cent excess of theory is specified. Preferably, the concentration of the hydroxide is about 30-40 per cent by weight.  Pressures should be sufficient to ensure a liquid phase reaction.  A mixture of the above monomer and trimer may be used, e.g. the product obtained by acid trimerization, and the trimer may be in solution in an inert solvent.  In examples, the monomer is treated in an autoclave in (1), (5) and (6) with aqueous sodium hydroxide at temperatures ranging from 260 DEG  to 360 DEG  C. and at pressures up to 190 atmos. gauge and in (4) with aqueous potassium hydroxide at 300 DEG  C. under pressure and in (2) the trimer, and in (3) a mixture of the monomer and trimer, are autoclaved with aqueous sodium hydroxide at 340-360 DEG  C. under pressure, and in all cases pimelic acid is separated after reaction times varying from 3 to 24 hours.

[Also in Group X] An expanded polystyrene article is covered with an impervious skin of thermoplastic material so that over at least a part of the surface of the article the skin hugs the depressions and prominences therein. Specified thermoplastic materials are all thermoplastics based on polymers or copolymers of vinyl chloride (e.g. polyvinyl chloride), polystyrene, cellulose acetate, polythene, acrylonitrile, butadiene and polyethylene terephthalate. Adhesive e.g. of polyvinyl chloride, may be applied to the surface to be covered or to the surface of the plastic sheet to be brought into contact with the polystyrene surfaces or to both surfaces. The plastic sheet material may be applied to only a part of the surface of the expanded polystyrene article or parts of the latter surface may be masked with material of strip form or of decorative shape and the sheet applied both to the masked and unmasked parts. As shown in Fig. 3 (which shows in cross-section an initial stage in producing a coated polystyrene article) an expanded polystyrene tile 10 has applied to its surface a mask 14 e.g. of cardboard, polyurethane foam, wadding or other material and is placed on a table 16 within a vacuum box 18 so as to cover a passage 20 leading to sources of pressure and suction. A decorative or plain plastic sheet 12, having adhesive applied to its under surface is placed on top of the vacuum box and clamped thereon by clamps 22 so as to seal the box. A radiant heater 24 is then brought over sheet 12 to heat it until it becomes soft and pliable. The heater is then removed and compressed air is supplied through passage 20 causing sheet 12 to be expanded upwards as shown in Fig. 4. Table 16 is then raised to bring the tile 10 near to sheet 12 and suction is applied through passage 20 whereby sheet 12 is brought down on to the tile 10 as shown in Fig. 5. The suction is then disconnected and the sheet cut around the sides of the tile. By supporting the tile 10 on grooved blocks with its edges projecting the sheet 12 may be drawn by suction around and under the edges of the tile.

Abstract: 999,768. Unloading by trimming. W. J. WALLACE. Aug. 18, 1961 [Aug. 19, 1960], No. 29926/61. Heading B8E. An endless chain of buckets is used to trim a mass of loose material by supporting the chain between horizontally spaced guides above the mass of material and allowing the lower run of the chain to hang freely so that when the chain is circulated the buckets ride over the mass and remove material from it. The trimmed material is subsequently dumped at a reversely curved bucket-inverting portion of the chain's upper run. As shown, for unloading material from a ship's hold 16, the guides are double sprocket wheels 32, 48 engaged with a double chain 58 between the individual chains of which the buckets are carried, the upper run 56 of the chain being supported above the ship's deck and the lower run 52 depending in a free catenary below it. By shortening or lengthening the chain, this catenary may be made to take up any of the forms 58 1  to 58 7 , or intermediately, in accordance with the depth of material in the hold. The chain may be passed through a guide at 86, which guide is reciprocable in a plane transverse to the plane of the Figure so that the chain of buckets may be swung across the hold from its normal central position to unload its marginal regions. The extra sprocket 60 is used to provide the reverse curvature in the upper run of the chain and thereby provide definite inversion of the buckets adjacent a take-away conveyer 72 into which the buckets are unloaded.
