Title: Water purification appliance - with spiral partition in flat cylindrical container
Inventor: HANKAMMER HEINZ
IPC: B01J47/012
Filed: 1979-06-23
Abstract: An appliance for the purification of water, esp. for households and restaurants, is a container of flat cylindrical shape which encloses the purifying agent (activated carbon, ion exchange resin). The inlet is in the centre of the top and the water is directed by spiral partitions to flow in a helical path to the outlet at the periphery. The pref. inlet connection is a rapid coupling with a restrictor nozzle. This extends the time of retention of a water flow in the purifying agent without excessive increase in height of the bed. Its compact design enables it to be coupled directly to a water tap.

Title: Radio receiver for spread spectrum multiple access signals - has noise immunity improved by including adder and subtractor circuits following code generator stage
Inventor: ROTHER DIETRICH DR ING
IPC: H04B1/707
Filed: 1979-07-11
Abstract: The receiver has an adder circuit (9) located between a code generator (8) and a multiplier (11). A subtractor circuit (10) is located between the code generator and a second multiplier (12). Both the adder and the subtractor circuits receive code sequences displaced by half a clock period such that the data is available at the output of the filter (13)in the path containing the adder. A third multiplier (15) is connected to filter circuits (13,14) and the output is coupled to the loop filter (17) in the delay locked loop that compresses the received signals in the baseband to the original bandwidth. The advantages include increased noise immunity using relatively few components. The receiver can handle smaller input signals than existing appts. and may make greater use of the available frequency band.
Patent DE-2929401-A1 (DE)
Title: Hot piercing of ingots for tube mfr. - esp copper ingots, which are heated and rolled over mandrel in skew mill in protective atmos. of nitrogen to preclude oxidn. of ingots
Inventor: UHLMANN OTTO
IPC: B21B3/00
Filed: 1979-07-20
Abstract: Metal ingots prone to oxidn. when hot, e.g. Cu ingots, are heated in a protective gas atmos. and then fed in a protective atmos. to a skew rolling mill fitted with a stationary mandrel, so each ingot is rolled over the mandrel to make a tube. The pref. atmos. is nitrogen, which also enters the rolling gap so the hot ingot is also protected against oxidn. during rolling. The pref. plant consists of a heating furnace followed by a skew rolling mill; and nitrogen in the furnace flows along tubes surrounding the hot ingot so the latter is shielded from air while being rolled. Ingots with bright surfaces can be heated to the rolling temp. without oxidn. and rolled in the absence of air, so no oxide is rolled into the surface of the tubes.
Patent DE-2932736-A1 (DE)
Title: Boiling water reactor - with cooling water level adjusted by condensate recycled from steam processor
Inventor: BEESE GUENTER DIPL ING
IPC: G21C1/08
Filed: 1979-08-13
Abstract: The output of a boiling water reactor, which is linked with a processor to form a cooling circuit, is controlled by moving control rods with neutron absorbent material into the core. The control rods dip into the core from the top with a normal density of 20-60%. To raise the power when the minimum rod density has been reached, the water level in the reactor pressure vessel is raised by recycling more condensate from the steam processor. The reactor can be operated economically even with a lower power density. It has therefore a high inherent safety and is esp. suitable for smaller reactors in development countries.

Patent DE-3002910-A1 (DE)
Inventor: HAGEN KARL DIPL ING DR
IPC: B30B11/02
Filed: 1980-01-28
Abstract: Moldings, for example hollow articles, are produced by sintering a thermoplastic powder or granular material and then reshaping the resulting blank by thermoforming. Sintering is carried out in a mold cavity under pressure, by exposure to high-frequency vibrations, which heats the plastic to a temperature intermediate between its softening point and its melting point. In this way, grain boundary adhesion between the individual plastic particles constituting the blank results, and the directly subsequent thermoforming can be carried out without additional supply of heat.

Patent DE-3106869-A1 (DE)
Title: Circuit for cancelling the resetting of a microprocessor
Inventor: LEUTHOLD OTTO
IPC: G06F1/30
Filed: 1981-02-24
Abstract: A semiconductor element handling the resetting is switched by the charge of a capacitor (3). This charge is periodically changed after a limit value has been reached and, as a result, the reset signal (R) of a particular period is generated in the semiconductor element. After the period has elapsed, the reset signal (R) is suppressed by a disturbance voltage opposing the charging-up of the capacitor (3). The circuit comprises a disturbance-signal circuit (1) and an oscillator circuit (2) containing the capacitor (3). The disturbance-signal circuit (1) is activated by squarewave pulses (UE) generated by the microprocessor and outputs differentiated and rectified disturbance voltages to the oscillator circuit (2). The oscillator circuit contains a multivibrator circuit, activated by the capacitor (3) and containing a comparator (7). The threshold voltage (US) for the non-inverting (+) input of the comparator (7) is generated from the supply voltage (VCC) by means of a voltage divider. The oscillating frequency and the period of the reset signal (R) is determined by the time constant of the capacitor (3) together with the resistance (13) and the threshold voltage of (US). <IMAGE>

Title: Casing for accommodating a web of material which is wound up into a roll
Inventor: NEUMEYER HANSJOERG
IPC: A47K10/38
Filed: 1981-03-12
Abstract: In the case of casings for accommodating a web (2) of material which is wound up into a roll (1), a receiving container (3) and a lid (4) are provided, a pulling-out slot (6) being provided in an edge region of the lid (4). It is especially important for the pulling-out slot (6) to be sealed off well when damp tissues are accommodated in the casing, in order to prevent drying out. To achieve this, a web (7) which projects in the direction of the casing aperture is provided at least in that edge region of the lid (4) which faces the pulling-out slot (6). When the lid (4) is closed, this web (7) extends parallel to the inner wall (8) of the casing over a large proportion of its width (V) . Effective sealing is therefore achieved practically by the web (2) of material itself in that area in particular over which the web (2) of material is pulled off. <IMAGE>
Patent DE-3109983-A1 (DE)
Title: Theft-proofing parking brake
Inventor: BIANCONE BRUNO
IPC: B60T7/08
Filed: 1981-03-14
Abstract: The mode of operation of the theft-proofing system is based on the existing hand brake device. The knob, which in handbrakes is generally installed in the centre console, for releasing the brake has been redesigned and is to be used for theft proofing. Installation of the new unlocking knob, which essentially comprises a lowerable locking mechanism, means that the handbrake can be lowered and locked in the top open "full braking effect" position. It is then no longer possible to release the handbrake. Unlocking, which is assisted by an additional spring, returns the release knob to its initial position. The handbrake can be released in this manner. The locking cylinder used should fit into the locking series of the vehicle in question. Installation can be performed easily, as essentially only the existing thread has to be adapted to the threaded rod and the upper region of the expansion slot has to be converted to function as a guide groove. This can be performed in advance if series installation is used. <IMAGE>
