Title: Improvements in grilles for use with griller pans
IPC: A47J37/06
Filed: 1939-07-20
Abstract: 531,368. Grilling-apparatus. ELLARD & SONS, Ltd., H., and ELLARD, E. F. July 20, 1939, No. 21052. [Class 28 (i)] In grilling-apparatus of the kind comprising a frame C and a rack D connected together by links D<SP>1</SP>, E such that movement of the rack in relation to the frame causes the rack to rise on the links which move from a substantially horizontal position to a substantially vertical one, stop means are provided in connection with one or more of the links so that when such links have passed the dead centre they are stopped from further movement and the rack is supported on the links acting as struts. As shown, the links E have extensions e with bent-in end portions and, when the rack is in its lowered position these portions engage under the rear member c<SP>5</SP> of the frame, and, when the rack is in its raised position, they encounter the members c<SP>1</SP> and stop further movement of the rack to the rear. In addition, when the rack is raised a foot b<SP>6</SP> in the rack handle b<SP>5</SP> passes over and behind the member c<SP>5</SP> to fix the rack against forward movement. The handle is formed as a rearward extension of the central rack bar, the bars at the two sides of that bar being made in one piece and joined by a looped member b<SP>@</SP> serving as a guide for the handle. A wire clip c<SP>7</SP> and a wire hook c<SP>6</SP> engage over the edges of the front and rear walls of the pan. According to the Provisional Specification when the rack is raised the bent-in portions of the rear links come under the short horizontal longitudinal portions of the side members of the frame; the rear member of the frame has a loop to engage under the handle of the pan, and the handle of the rack can be regulated by a screw device.

Title: Improvements in or relating to gasometer vessels for the methane fermentation of manures and other like materials
IPC: C12M1/107
Filed: 1947-08-05
Abstract: <PICT:0621772/IV (b)/1> Apparatus for effecting the methane fermentation of manure and similar substances as in the parent Specification, is characterized by the provision of a trough in the fermentation vat to form the liquid seal, said trough being spaced from the lateral wall of the vat.  The trough 3 forms a liquid seal at the lower edge of the dome 2, the outer wall preferably being higher than the inner which is immersed, at least upon commencing operation, in liquid, whereby escape of gas at the bottom of the same is prevented.  Manure may be compressed in the vat and subsequent swelling during fermentation is possible while permitting free movement of the dome.  Air may be admitted under pressure from pipe 4 beneath plate 5, and gases collected in pipe 6.  Liquid is withdrawn by syphon 7, and charging effected through manhole 8. Fermentation occurs in three stages: (1) aerobic, breaking down toxic materials, (2) anaerobic, breaking down proteins, and (3) anaerobic methane fermentation of cellulose.

Title: New cellulose derivatives
Inventor: ZENFTMAN HENRYK
IPC: C08B15/06
Filed: 1962-06-01
Abstract: Difluoraminated derivatives of cellulose are made by treating dialdehyde cellulose with liquid difluoramine in an inert atmosphere in the presence of an acid catalyst.  The reaction may take place under reflux at -23 DEG  C. in a current of nitrogen using excess difluoramine. In order to avoid degradation of the dialdehyde cellulose, preferably a first stage is carried out in the absence of the acid catalyst; in a second stage concentrated sulphuric acid is added as the catalyst.  Excess difluoramine is distilled off and the white solid product washed with water. Dialdehyde cellulose is made by treating cotton linters with an aqueous solution of paraperiodic acid and soium acetate.  The difluoraminated derivatives are useful as explosives and rocket propellants; more energetic explosives may be made by esterification with nitric acid.

Abstract: 1338437 Polyvinyl chloride and vinyl chloridepolyalkenamer graft copolymer compositions MONTECATINI EDISON SpA 19 April 1971 [24 Feb 1970] 21954/71 Headings C3G and C3P Compositions comprise polyvinyl chloride and a graft copolymer(s) of vinyl chloride and a polyalkenamer(s). The polyalkenamer(s) may be polypentenamer(s). The copolymer may contain 20-40% wt. Cl. The compositions may also comprise polystyrene, in which case they comprise 10-20% wt. polypentenamer. The composition may have high impact resistance and high transparency, transmittance values being 40-80% of the incident light. The copolymer may be formed by graft polymerization in bulk, emulsion, solution, or suspension, or by bulk-suspension or solution-precipitation. An intiator may be used 0À1-10% wt., based on total reactants, of organic peroxides, ammonium persulphate, azi-bis-isobutyronitrile, or hydroperoxides + reducing agent. The reaction may be performed at 0-100 C. in the presence of M.W.-regulators, e.g. mercaptans. As solvents, aliphatic or aromatic hydrocarbons may be used. In suspension, 0À2-1% suspending agents may be used. For emulsions, a slurry of the polymer in a solvent is dispersed in water in the presence of surfactants, preferably followed by removal of the solvent under reduced pressure. In Examples (1a) polypentenamer is prepared by bubbling air through cyclopentene, and polymerizing at -30 C. in the presence of WCl 6  and Al diethylmonochloride in mole ratio 1 : 5, mole ratio of WCl 6  : cyclopentene being 1 : 120. The polymerization is interrupted by addition of CH 3 OH, the mixture being added to a CH 3 OH/HCl mixture, precipitating the polymer, which is worked up and dried. The product has intrinsic viscosity of 1À7 dl/g (in toluene at 30 C.), and has predominantly trans structure. (1b) The polymer is emulsified with water to give a latex containing 8À9% polymer. (1c) 225 g. of the latex and 35 g. vinyl chloride are reacted in the presence of sodium hexametaphosphate, cumene hydroperoxide, and sodium formaldehyde sulphoxalate at 38 C. in N 2 . The emulsion formed is coagulated in CH 3 OH, yielding a 50/50 polypentenamer/polyvinylchloride graft copolymer. (2) 22 g. solid polypentenamer and 200 g. vinyl chloride are reacted in the presence of water, polyvinyl alcohol, and benzoyl peroxide, in N 2 , at 65 C. 35 g. material containing 38À2% bound polyvinyl chloride results. In each example, the copolymer is blended with polyvinyl chloride. The composition contains 9% polypentenamer, and is stabilized with 2% of a barium stearate/Cd powder coprecipitate and 0À1% phenolic antioxidant. It is mixed at 185 C. and compression-moulded at 180 C. Rejerence has been directed by the Comptroller to Specification 1,250,418.
