Title: Dough for potato dumplings - is produced by partly boiling potatoes to leave raw core in each
Inventor: TOEPFER HANS-JOACHIM
IPC: A23L19/12
Filed: 1978-12-21
Abstract: The parent patent described a method of makign dumplings from a mixt. of raw and boiled potatoes. Instead of mixing raw potatoes with boiled potatoes to achieve the desired ratio between them, in this addn. the potatoes are immersed in a boiler with boiling water. The temp. in the boiler drops and when the temp. has reached 80-95 degrees, the potatoes are extracted. It is found that each potato has a raw core which makes the ratio right for the desired dumplings. This simplifies the process and ensures a uniform product.

Title: Aldehyde dry gas autoclave - with easy sterilising soln. dosage and program control of heating cycle
IPC: A61L2/20
Filed: 1979-01-26
Abstract: Aldehyde-dry gas autoclave for sterilisation purposes consists of a pressure vessel in which a drawer is used to insert a bag with a sterilising soln., to be opened by depressing a spiked hinged lid. A waste gas pipe leading to a condenser is fitted with a spring loaded valve. A temp. control effects a repeated heating of the pressure vessel. The pressure vessel has a compartment in which a bag with the sterilisation soln. can be inserted. The depression of the spiked lid pierces the bag and releases the soln. A spring loaded valve in the condenser prevents the re-entry of water in the waste gas line. An electrical heater is connected to a thermostat and a timer via a pressure monitor. This simplifies dosage and improves the functional reliability and efficiency of the sterilisation.

Title: Control system for electrically-driven vehicle - uses voltage divider with magnetic, sequentially-operated switching contacts with series resistances
Inventor: KAHLEN HANS DR ING
IPC: H01C1/16
Filed: 1979-01-31
Abstract: The control system for an electrically driven vehicle includes a desired value unit having four series resistances (R1 to R4) forming a voltage divider. At the junction points between the resistances are connected switching contacts (S1 to S5) each in series with a further resistance (W1 to W5). The ends of all these latter resistances, remote from the switches are all connected by a common line to an output point (A). The switches are operated in sequence, and when all switches are open, the latter resistances ensure that there is not a false reading in the absence of a current flow. Either one switch or two adjacent contacts can be operated sequentially. The contacts can be magnetically operated vacuum contacts, or can be moved by a sliding permanent magnet.

Title: Extruder screw - in which multiple threads in fusion zone have twin flow paths where one has sickle shaped section
Inventor: GRUENSCHLOSS EBERHARD DIPL ING
IPC: B29C48/07
Filed: 1979-08-24
Abstract: A multiple-thread extruder screw for thermoplastics/elastomers, with normal height crests, has at least one shear/ blending length with at least one pair of flow passages consisting of a spiral entry path and a parallel outlet path; these paths are separated by a normal height thread crest when viewed circumferentially and in the direction of screw rotation, or the entry path leads the outlet path when viewed against the rotation direction. The downstream end of the entry path and the upstream end of the outlet path are blocked where the gap between the blockage and barrel is at least equal to the gap between the normal height thread and barrel. The root of the entry path, viewed circumferentially agand against the rotation direction, is tapered to form a sickle-shaped cross-section between root and barrel, and its narrowest width is greater than the gap between the normal height crest and the barrel. Thermally and mechanically homogeneous extrusions are obtd. Low temp. and low pressure at the start of the fusion zone enable low flow resistance at transition to the entry zone.

Title: Isothermal quenching tank for workpieces leaving hardening furnace - where workpieces are transferred from molten salt bath to hot air duct by conveyor belt
Inventor: DREIZLER GERHARD
IPC: C21D1/44
Filed: 1979-09-28
Abstract: Workpieces leaving the furnace drop through an opening into a heated bath, e.g. a molten salt bath. In the bottom of the bath is a conveyor, which lifts the workpieces out of the bath so they next travel through a current of heated air which passes through the molten bath. The times that the workpieces spend in the bath and in the hot air produce a complete transformation of the structure of the pieces. In one pref. plant, both a salt bath and hot air channel are fitted with wheels located on rails, so they may rapidly be replaced by similar units contg. another molten salt for a different isothermal treatment.

Title: Heat exchanger with coil housed between double walls - uses space between windings as flow path for medium overflowing inside
Inventor: HAGEDORN RUDOLF
IPC: F28D7/14
Filed: 1979-11-02
Abstract: The heat exchanger with a vertical cylinder (23) acting as a reservoir, contains a heat exchanger coil (5) housed in a compartment (25) formed by an inner tube (6). Liquid entering through a bottom connection (7) travels around a path (24) between the coils, and overflows over the top of the inner tube, to discharge into the space inside the inner wall. The inner wall is of smaller height than the outer wall, and the coil is attached to it, forming the flow path for the second medium. In one design, the tube for the first medium can be a double coil. Another design uses ribbed tube. The supply and return pipes for the coil can pass through the cover (2) of the vessel or through the outer cylinder.

Title: Recovery of radioactive xenon from exhaled air - after radio-medical diagnostic procedures by adsorption on active charcoal and subsequent desorption
Inventor: BOLMSJOE MAGNUS SVEN
IPC: B01D53/04
Filed: 1980-01-04
Abstract: In a new process for the recovery of radioactive xenon from exhaled xenon-contg. air obtained in radiomedicinal diagnostic investigations, the xenon-contg. exhaled air is passed through a first active charcoal bed at 0-50 degrees C to adsorb the xenon. This active charcoal bed is then heated to 200-400 degrees C and an inert, moisture-free gas is passed through it to desorb the xenon. The desorbed xenon is passed to a second active charcoal bed, contg. a smaller amt. of active charcoal than the first active charcoal bed, where it is adsorbed at 0-50 degrees C. The second active charcoal bed is then heated to 200-400 degrees C and an inert, moisture-free gas is passed through it to desorb the xenon, then the resulting xenon-contg. gas is collected. Used in collection of radioactive xenon from exhaled breath after diagnostic procedures such as functional lung studies or blood flow measurements. Simple technique giving almost quantitative recovery of radioactive xenon in a sufficiently high concentration for re-use in further radio-diagnostic studies.
Patent DE-3002146-A1 (DE)
Title: Semiconductor chip charge transfer structure - has digital one and zero charge holding zones with higher return flow in one zone
Inventor: ROEDDE KLAUS DIPL PHYS
IPC: G11C19/28
Filed: 1980-01-22
Abstract: The charge transfer system based on a substrate has a signal path at the input of a weir zone having an input diode and a trough zone whose charge holding capacity is limited by the height of the weir zone. This also limits the return flow, resulting in a singla charge according to a digital one value. A basic charge branch with an input diode is followed by a barrier zone for a barrier potential and a second trough zone for a second potential, also with a second trough zone for a second potential, also with a return flow limitation. This results in a signal charge with a digital zero value less than the other charge. The first and second branches are followed by a common trough zone having a charge holding capacity for the digital one charge and a return flow capacity for exceeding the charge only in the direction of the second basic charge branch.
