Filed: 1928-06-21
Abstract: 294,146. Junkers, H. July 18, 1927, [Convention date]. Propelling.-The shaft if a high-speed aircraft &c. propeller is mounted so as to be free to swing about a point at the end 6 remote from the propeller, and in the neighbourhood of the propeller is supported by a spring bearing 15 which permits such swinging. The shaft is able, therefore, to align itself so that the centre of inertia lies in the axis of rotation, and oscillations due to un balance are avoided. The arrangement is illustrated for a geared shaft, but is applicable also to a shaft direct-driven through a universal joint. The bearing 15 may be mounted in its housing by leaf-springs 16, which are advantageous for their damping effect, or by helical springs, rubber blocks, &c. In the form shown in Fig. 3 the bearing 15 is coupled to its housing 25 by bundles 22 of steel wires.

Abstract: 1382097 Drying chicken manure ANIAGRA PRODUKTIONS AB 19 April 1972 [20 April 1971] 18029/72 Heading F4G Chicken manure is dried by evaporation in an apparatus in which substantially all the released gases and vapours are prevented from escaping to atmosphere, the gases and vapours being condensed and collected. In this way, evilsmelling substances are not released to the atmosphere. In Fig. 3, fresh manure is supplied from a poultry-house via a compressed gas pipe and a shoot 4 on to two counter-rotating rollers 2 and 3, remains on the rollers for a half revolution and is then scraped off. A condenser 5 for the gases and vapours comprises vertical watercooled panels below which are drainage shoots 6. Air (or nitrogen) and remaining vapour are sucked from hood 7, heated and returned to the rollers 2 and 3. Additives such as phosphoric acid or sawdust may be added prior to drying. The heated surfaces of the drier may be powdered with talc to prevent sticking. The condensate may be treated with chlorine or chlorineyielding substances. Means are provided for controlling the amount of manure dried. The product may be formed into pellets &c. after drying, or during two-stage drying.

Title: Method of and apparatus for regulating a heat power plant
IPC: F02C3/36
Filed: 1939-06-21
Abstract: 530,336. Gas turbines. MASCHINENFABRIK OERLIKON, and KARRER, W. June 21, 1939, No. 18100. [Classes 110 (iii) and 122 (iii)] A gas turbine or other power plant, in which the gases are heated at constant volume before admission to the power engine, is governed by regulating the pressure at which the gases are delivered to the heating chambers. Gases heated by burning fuel in chambers 2, operating in succession, are passed by valves 14 to a turbine 5 thence to a pressure equalizing tank 7, a preheater 1<1> and an intermediate heater 11. Thereafter, the gases enter the pipe b, mix with the residual gases of the chambers 2 and pass to a turbine 6, the intermediate heater 11, a final constant speed turbine 8 and the heat-exchanger 1. Fresh air from the compressor 4 passes by valves 12, to the chambers 2 and expels the residual gases by valves 13 into the pipe b. When a chamber is full, a closed circuit is established by valves 15, 16 and a pump 9 circulates the air through the heat-exchanger 1 and the preheater 1<1>. The chamber is then isolated and the air is heated by burning fuel in it and the cycle re-commences. Turbines 5, 6 drive the air-compressor 4 and the turbine 8, producing useful power, drives an electric generator 10. If the external load alters, more or less fuel is admitted to chambers 2 and the gas temperature is raised or lowered temporarily thereby. The increased or diminished power yielded up in the turbines 5, 6, and the consequent increase or decrease in their speed, alters the delivery of air to suit the added fuel and the system returns to the normal temperature but at a higher or lower initial pressure. The initiation of the control may be effected, in place of control only of the fuel, by a temporary variation of the change-over periods of the control valves 12-16 or by suitable variation of one or more of the turbines. Or, when the load is increased by the use of extra power gas stored in a tank 20, and, when the load is decreased, by byepassing stages of the compressor or of the turbines driving it.

Title: Process for the manufacture of tubular containers made of plastic material
IPC: B29C45/14
Filed: 1957-06-12
Abstract: 831,159. Moulding plastic containers. MAINARDI, T. June 12, 1957 [June 12, 1956], No. 18535/57. Class 87(2). A process of making "headed" tubular containers utilising the container cap as part of the mould comprises placing a cap 3 in the cavity 8 of a mould 1, placing a plastic tube 4 over a mandrel 2 so that an end 4a of the tube 4 protrudes over a shoulder 10 of the mandrel 2, placing the mandrel 2 in the mould 1 so that the end 4a of the tube is pressed between the shoulder 10 and the mould and the mandrel end firmly holds the cap 3 against the mould, injecting plastic material into the mould so that the plastic material fills the gap between the cap 3 and mandrel 2, unites to the end 4a of the tube and moulds a head on the tube. The end of the mandrel has facets 13 and grooves 12 and, during moulding, plastic material fills the grooves 12 but leaves holes in the moulded head of the tube where the facets 13 contact the cap, which holes are normally covered by the cap and exposed when the cap is removed. In a second embodiment, Fig. 5 (not shown), the end of the mandrel is flat and is pressed against an imperforate cap which is spaced from the bottom and sides of the mould cavity so that during moulding the plastic material first flows around the extension of the cap and then inside the cap to mould a tube head with a cap that is " sealed " on its exterior by a film of plastic material. The cap may be of metal or of a higher melting point plastic material to that of the tube and head.
