Title: Fryer
IPC: A47J37/12
Filed: 1984-12-05
Abstract: The deep-fat fryer has an upper basket (41), a heating source (8) below and a heat exchanger in between (13) for the exchange of heat between a gaseous heat exchange medium (57) and the frying oil (55). Thereby thermosiphonic oil circulation results. A blower (29, 31, 32, 33) is arranged, whereof a blower rotor (31) imparts a higher velocity of flow to the heat exchange medium (57) in the heat exchanger (13). The blower (29, 31 through 33) is arranged in the fresh air supply duct (56), in the gas vent (57) and in the cool air supply duct (58) for cooling the flue gases. The three blower wheels (31 through 33) are arranged on one and the same drive shaft (30). This deep-fat fryer takes significantly better advantage of the heat conducted to it. With large energy densities relative to the oil volume, it has minimal specific heating surface loadings and thereby affords optimal relationships.

Title: Driver brake valve
IPC: B60T13/66
Filed: 1985-02-22
Abstract: Driver brake valve for operating compressed air brakes of rail vehicles. An electropneumatic converter is used to generate a servopressure. The servopressure actuates a relay valve for pressurizing a main air line. An electronic regulation circuit receives a plurality of electrical control signals, including a signal proportional to the pneumatic servo-pressure. The regulation circuit generates an ideal value signal for controlling the electro-pneumatic converter and controls the starting behavior of the brake system. Brake demands which exceed a threshold value are applied to the electronic circuit which generates the ideal value signal. Pressure sensors connected to the main air line and a flow sensor connected to a main container line are used to derive the ideal values for controlling the pneumatic servopressure and the operation of the relay valve.

Patent EP-0227352-A3 (EP)
IPC: C22C32/00
Filed: 1986-12-03
Abstract: A composite material comprising a refractory, 
inorganic filler material (e.g. SiC or Al₂O₃) in a 
matrix of aluminium or an aluminium-containing alloy is 
made by incorporating the filler material into the 
aluminium or aluminium-containing alloy at a temperature 
above its liquidus, e.g. by vacuum stirring, followed by 
cooling to solidify the composite. In order to improve the 
wettability of the filler by the molten metal, the filler 
has a bismuth additive, for example in the form of a 
bismuth compound such as bismuth oxide, dispersed therein. 
This may be done by intimately mixing elemental bismuth 
with particulate filler followed by oxidation of the 
bismuth to bismuth oxide. e.g. by heating in air.
