Title: Improvements in or relating to rotary-scythe type lawn mowers
IPC: A01D34/49
Filed: 1970-07-01
Abstract: 1278157 Rotary-scythe lawn mowers VICTA Ltd 1 July 1970 [2 July 1969 8 April 1970] 31782/70 Heading A1F A rotary-scythe lawnmower is fitted with a discharge chute to facilitate the efficient removal and collection of grass cuttings. The chute 31 is of a spiral form around the baseplate 12, extends over a major portion of the cutting circle, and has a substantially uniformly-rising helix angle throughout its length (in this embodiment, 11‹). The chute is built into the underside of the baseplate, and, with the cutting blades rotating clockwise as viewed from above, commences on the port side of the baseplate at a point 33 substantially on the transverse centre line. A fanning-out of the discharge stream is effected by an inward depression 39 in the outer wall of the tunnel 22, and the cuttings pass into the grass-catcher 27 over a greater width of the exit port in the rear wall 26. The chute is of a shape enabling the engine to be accommodated within its confines, and the low engine-mounting level 15 results in a shorter crank-shaft length (with the engine in a transverse alignment to the fore and aft direction of the baseplate), thus giving better resistance to operational shocks. The exhaust pipe of the engine can be turned downwardly to discharge directly through a port 43 in the floor of the baseplate. Also, an air-port 44 can be provided to draw cooling air over the cylinder cooling fins of the engine. A pivoted safety flap 28a is connected to the rear side of the wall 26, controlled by a spring catch mechanism 28, to allow the safe removal of the grass-catcher.

Title: Manufacture of highly polymeric polymethylene terephthalates
Inventor: FLETCHER NORMAN
IPC: C08G63/87
Filed: 1958-10-08
Abstract: In a process for making highly polymeric polymethylene terephthalates by reacting a dialkyl terephthalate with a glycol of formula HO(CH2)nOH, where n=2-10, in the presence of a compound of an alkaline earth metal (i.e. Ca, Ba, Sr or Mg) and converting the alkaline earth metal, prior to polycondensing the esterinterchange product, wholly or in part, to a phosphorus-containing compound of that metal which is catalytically inert, polyesters of an improved colour are obtained by effecting polycondensation in the presence of a pentavalent antimony compound.  Specified ester-interchange catalysts are magnesium carbonate, magnesium oxide and salts of Ca, Ba, Sr or Mg with aliphatic or aromatic carboxylic acids (e.g. calcium acetate); these may be used in admixture with cobalt acetate. These catalysts may be converted into inert phosphorus-containing compounds by addiing to the ester-interchange product phosphoric acid, phosphorus acid, an alkyl phosphate or phosphite, an aryl phosphate or phosphite (e.g. triphenyl phosphite), a glycol phosphate or phosphite, or an ammonium phosphate or phosphite.  Specified polycondensation catalysts are antimony pentoxide, antimonic acid, antimony pentachloride, antimony pentafluoride, magnesium antimonate, pentaethyl antimonate and antimony pentaglycoxide.  Titanium dioxide may be added to the polyesterification mixture to act as a delustrant. In addition to the dialkyl terephthalate, and polymethylene glycol, minor amounts of esters of other acids (e.g. isophthalic, phthalic, adipic, sebacic, glutaric or naphthalic) or other glycols (e.g. hexahydrop-p-xylylene glycol) may be used as starting reactants.  Examples describe the manufacture of polyethylene terephthalate from dimethyl terephthalate and ethylene glycol.  Specification 802,921 and U.S.A. Specifications 2,650,213 and 2,739,957 are referred to.ALSO:Antimony pentaglycoloxide is made by dissolving pentaethyl antimonate in ethylene glycol by warming, allowing the mixture to stand and centrifruging off the resulting crystals which are then washed with methanol and dried.  It is stated that the product probably contains ethylenedioxy groups in addition to hydroxyethyl groups.

Title: Improvements in or relating to the manufacture of artificial silk, fibres, films and the like
IPC: D01F2/04
Filed: 1934-11-08
Abstract: Artificial silk, fibres, films, ribbons, and other materials are obtained by projecting cuprammonium cellulose solutions into an aqueous weak coagulating agent containing dissolved therein a small quantity of a phosphoric acid or a water-soluble salt thereof, i.e. up to about 0,3 or 0,5 grams per litre respectively and completing the coagulation in a subsequent bath. The process is applicable to stretch-spinning processes where the extruded thread is drawn out in the weak coagulating agent and then hardened in an acid bath. Ortho-, meta-, and pyro-phosphoric acids or their water-soluble salts may be employed.  The aqueous precipitating bath may also contain sodium chloride, sulphate, or bicarbonate, or carbonic acid.  In examples, artificial silk is obtained from cuprammonium cellulose solutions by stretch-spinning in water containing small quantities of phosphoric acid, or disodium o-phosphate, or trisodium o-phosphate together with sodium bicarbonate, sodium sulphate, and carbon dioxide, coagulation being completed by treatment of the threads with sulphuric acid solution.  The Provisional Specification describes also the application of the process to the production of artificial silk and other materials from viscose.

Abstract: 784,413. Cylinders. DIESEL ENGINE CO. OF TEXAS. Nov. 9, 1954 [April 17, 1954], No: 32440/54. Class 7(2) Satisfactory self-ignition of a compressed fuel-air mixture under different engine operating conditions is provided by continuous or step-wise clearance volume variation effected by differential thermal expansion of cylinder parts respectively of cast-iron, steel, nickel, nickel-steel or other low thermal expansion rate material and of zinc, aluminium or other high thermal expansion rate material. A cylinder head (Fig. 1, not shown) may comprise a cylindrical member of high thermal expansion rate which may be surrounded by thermal insulation and has secured to its upper end a piston-like. member of low thermal expansion rate the lower face of which forms a combustion chamber top movable to effect the required clearance volume variation. The piston-like member may have a packing collar or a piston ring or rings. In Fig. 2, differential radial expansion of a ring 15 and a member 13 sealed by a diaphragm 23 allows a spring 22 to draw the member 13 upwardly with increasing engine temperature. The top face of the ring 15 may co-act with the cylinder cover 20 or with a further member 17 of low thermal expansion rate, and there may be additional rings and members. In Fig. 3 lateral expansion of a ring 36 of high thermal expansion rate uncovers entries 40 to a supplementary combustion chamber 39 in a member 37 of low thermal expansion rate depending from the cylinder cover. In Fig. 6 an initial interference fit between co-acting conical surfaces of members 44, 52, respectively of low and high thermal expansion rate, is relieved as engine temperature rises, allowing the member 44 to move upwardly under combustion pressure against the restraining action of a liquid or pneumatic dashpot 54 or of a spring. The conical surfaces may be dispensed with, the initial interference fit being between cylindrical sliding surfaces of the members 44, 52.
