Patent DE-4111253-A1 (DE)
Inventor: RAEHSE WILFRIED DR
IPC: A23K10/22
Filed: 1991-04-08
Abstract: An improved process for sanitizing and if necessary for at least partially drying waste and/or valuable substances from recovered animal corpses, in particular in connection with the sterilization of valuable substances for the preparation of animal fodder, is characterized by subjecting the material to be sanitized to drying process conditions with superheated water vapour at least for a period sufficient to ensure the required sterilization. This process is suitable for eliminating pathogenic germ infestation and in particular for ensuring the quality of valuable substances or valuable substances-containing residues of animal origin, preferably at least partially dried. It can be used in combination with the recovery of animal fodder additives of vegetable origin by drying and if necessary by disintegration of the corresponding vegetable matter with superheated water vapour.
Patent DE-4112198-A1 (DE)
Title: Room humidity warning method - involves measuring room temperature over long period to determine critical point
Inventor: RAATSCHEN WILLIGERT DR ING
IPC: G05D22/02
Filed: 1991-04-13
Abstract: The system gives warnin of excessive relative humidity in a room, or reduces it by cutting in a fan or moisture-extractor.  The momentary operating point for the humidity level is determined by surface-temp. measurement at a critical point in the room and also the room temp. A control criterion is taken into account which ensures over a longer period (e.g. a month) a mean value gives conditions at the most critical point in the room which safely prevents growth or multiplication of mould fungi. ADVANTAGE - Simplicity and min. power consumption.
Patent DE-4113651-A1 (DE)
Inventor: SCHREIBER HANS DR DR
IPC: A61C13/38
Filed: 1991-04-26
Abstract: The invention relates to a process and device for the production of especially dental saw-cut models in which for at least one saw blade (2), the direction of cut to produce a dental saw stump is established via a separation light provided in the blade plane and displaceable vertically, a laser beam (19) or the like. Thereby the process of the invention provides the great advantage that, in difficult situations a saw-cut is directed especially from the side and below to a predetermined breaking point, thus avoiding the risk of damaging neighbouring and unground tooth crowns, whereby a second light source at right angles to the first limits the saw-cut.

Title: Cocoa butter and powder prodn. - by centrifugal action to cacao mass emulsion, to remove unwanted matter and separate butter from powder
IPC: A23G1/04
Filed: 1991-12-03
Abstract: The continuous process to recover cocoa butter and powder, from a cocoa mass, has an initial roasting stage for the cocoa means followed by shelling. The cocoa bean kernels are reduced to a fluid cocoa mass in a watery emulsion to be separated into three components in a centrifugal action under high-speed rotation. The unwanted matter is spun out and retained matter is separated to give a pure and flavoursome cocoa powder and butter. ADVANTAGE - Eliminates fatty acids which would affect the taste. In an example, 1000 kg of finely chopped cocoa mass is produced from roasted and shelled Ghana cocoa beans, with well fermented kernels, and held in a V2A stainless steel vessel with a capacity of 7500 litres with a mass temp. of 65 deg.C for 15 mins., together with 5000 litres of water heated to 75 deg.C fed in over 15 mins. After filling, the matter is converted into an emulsion by a turbo mixer operating at 3000 rpm for 10 mins, and then passed to a V2A stainless steel tank with a slow paddle agitator rotating at 60 rpm. The emulsion is withdrawn continuously from the tank, within 30 mins., into a horizontal centrifuge operating at 32000 rpm with continuous take-off of thick matter. The cocoa butter which rises to the upper layer is separated and taken off to be pumped into an intermediate tank. The second layer thickness contains water with dissolved matter such as theobromine, the water soluble tannic matter and lower fatty acids and other substances with unpleasant smells. Additionally other substances are washed out such as soluble carbohydrates, pentoses, pentosane, xylane, galactans, araban etc. The thick matter portion, taken off continuously, is dried in a V2A double roller stainless steel vacuum dryer at a temp. of 75 deg.C to give a residual moisture content of 2.9%. The precipitated fine flake powder, with a pleasant light caramel-smelling character, is recovered at the rate of 41.2.8 kg with a residual fat content of 3.1%. The cocoa butter, in a recovered volume of 546.5 kg, is given a further rapid centrifuge spinning in the intermediate store vessel, to extract any small amts. of water for safety, and then chilled into blocks.

Abstract: To prepare mixts. of stone or ceramic materials for subsequent shaping or hardening, two basic mixts. are laid in layers at separate points on an underlay or a rotating drum. The rotary speed is set so that each applied layer is spread out and the layers of mixts. are homogenised by rotating or fixed units. The final mixt. is unloaded and transferred to the next processing stage. The final mixt. is pref. removed by semi-circular paddles which can take the place of the homogenising action of the rotating or fixed units. USE/ADVANTAGE - The mixed materials are for mfg. plates or blocks together with a bonding cement or resin, and can be based on recycled stone and ceramics. The technique saves on the space required by numerous conveyor belts, and also reduces maintenance time and costs.
