Title: Gas turbine fuel distributor - has additional temperature dependent valve to stabilise fuel feed
Inventor: DMITRIEV VASILIJ PETROVITSCH
IPC: F02C9/32
Filed: 1975-09-17
Abstract: A gas turbine fuel supply system has a distributor (1) in the fuel delivery pipe (2) to the main collector (5) and vapouriser jets (6). The distributor housing contains a jet (11) and two valves (12, 13) in parallel. Fuel is regulated to the distributor by a valve (4) dependent upon the final compressor stage pressure (P2) and a centrifugal governor (28). One distributor valve (13) has a larger cross section than both the second valves (12 and the jet (11) and responds to a signal from the engine revolution counter to decrease the fuel flow to the collectors (5, 8). The second distributor valve (12) consists of a hollow sprung plunger able to slide inside a fixed sleeve. Both plunger and sleeve have fuel transfer borings. The plunger is moved by the spindle of a thermal unit responding to environmental temperature changes.

Title: Hydrolysis of cellulosic materials - using phenol or derivs. contg. reduced amounts of mineral acid
Inventor: TAMMELA VILJO
IPC: C08B15/02
Filed: 1975-09-18
Abstract: Hydrolysis of cellulosic materials is effected using phenol or derivs. contg. mineral acids, at elevated temps. It is used in the mfr. of micro-crystalline cellulose by milling the residue from hydrolysis to break up the micro-crystal bundles. Much reduced amts. of mineral acid, around, 0.8-1ml/g. cellulose of 0.1-1 N acid, are required which reduces problems of subsequent neutralisation and plant corrosion. In an example, bleached sulphite cellulose is heated with a mixt. of phenol and 0.09N Hcl in vol. ratio 8:1 approx., for 30 mins. at 110 degrees C. After washing, drying and milling, a white powder is obtained.
Patent DE-2546643-A1 (DE)
Inventor: RISI RENE
IPC: G04B19/253
Filed: 1975-10-17
Abstract: The essential element of the device is a toothed switch wheel (8), arranged between date ring toothing (3) and day-of-week ring toothing (4). Two switch tongues (12, 13) are punched out from the said switch wheel and bent out from a plane of the latter. These tongues run essentially radially and protrude with their ends to different height levels. The tongue (12) with the higher-lying end forms an acute angle with the plane of the switch wheel. The aims in particular are to make production more simple and to make the switch wheel less expensive. <IMAGE>

Title: Mfr. of plastics moulding having solid skin and cellular core - by initially keeping the temperature of the moulding compound below reaction temperature of the foaming agent and then raising it
Inventor: LANDLER HEINRICH
IPC: B29C44/04
Filed: 1976-08-05
Abstract: Plastics mouldings having solid skin and cellular core are mfd. by injecting a moulding cpd. contg. a foaming agent into a mould; initially holding the temp. of the cpd. below the reaction temp. of the foaming agent; and then raising the temp. of the cpd. in the region of the injection nozzle to above this reaction temp. The heat required for this later operational step is derived by increased friction of the moulding cpd. in the nozzle zone. The process is independent of time-consuming heat transfer which is unavoidable when heat supply from external sources is used. The process is used for processing e.g. polystyrene contg. azodicarbonamide, as foaming agent.
