Patent DE-2844392-A1 (DE)
Title: Flowmeter with low signal scanning - has float axially guided into conical pipe so that its position is detected by coils outside pipe
Inventor: ROGG WERNER
IPC: G01F1/24
Filed: 1978-10-12
Abstract: A cone with a centrally guided float is placed in a pipe, and a temp. sensor is provided for density and viscosity compensation. Coil(s) are mounted at specified positions outside the pipe which, when connected, convert the float movement into an electric signal as a function of the flow. The float (3) is centered by the flow inside the cone (2) and also by a rod (4) rigidly connected to the float (3) and provided with a restoring spring (5). thus, a position insensitive and proportional to the flow float (3) deflection is achieved. The float (3), cone (2) and coil(s) (6) can be stacked in parallel so that the movement of the float against the wall strength of the cone serves to produce the signal.

Title: Tamper-resistant lock for heating cost distributor - uses sliding plunger to locate in slotted fixing screw head
Inventor: PETZOLD LUDWIG
IPC: G01K17/02
Filed: 1978-11-25
Abstract: The heating cost distributer determines the heat output of a radiator. The distributer is clamped to the radiator by screws (10, 11) which are connected to the clamps (12, 13). The top screw is tightened on to the heat conductor (7) to provide the conductor path. The screw cannot be loosened without releasing the lower screw. The lower screw provides a tamper resistant lock. The locking mechanism consists of a plunger and a slotted screw head. The plunger end drops into a slot to hold the screw. The plunger position is controlled by a guide block held in place by two rivets. A stop block prevents the plunger from falling out. The screw head can only be turned by a special six-sided screw driver which connects to a locating stub (14). Inadmissible access causes the rivets to be deformed and the seal (6) to be broken.

Title: Pulverised solid fuel processing - absorbs heavy gums on solid particles by spray cooling
Inventor: TSCHUCHANOV ZINOVIJ FEDOROVITS
IPC: C10B49/08
Filed: 1979-03-22
Abstract: Fuel is processed by heating a gaseous heat carrier to 300 -500 degrees C for =1 sec, followed by a rise to 500-800 degrees C for one second. The produced vapour/gas suspension is divided into solid particles and a vapour/gas mixt, and the latter is purified and condensed. Before the separation of the vapour/gas suspension it i cooled by direct contact with a coolant to 140-360 degrees C so that the heavy gums are absorbed by the dust particles of the solid matter. The gum absorption raises the calorific value of the solid product and makes it suitable for hydraulic transport. Any dust made is practically eliminated.

Title: Motorcycle hydraulic brake system - uses pressure reduction valve, acting on rear brake when foot and handbrakes are applied
Inventor: LUEPERTZ HANS-HENNING DIPL ING
IPC: B60T8/26
Filed: 1979-04-30
Abstract: The hydraulic braking control for a motorcycle has a footbrake circuit, operating on the front and rear brakes, and a handbrake circuit operating on a second front brake, while at the same time reducing the rear brake pressure. This prevents slewing during heavy braking. The footbrake circuit has a pressure reduction valve between the master brake cylinder and the first front brake, with the reduction valve fully open where a set pressure level is reached. This ensures stable brake control for normal use, with the rear brakes applied fractionally before the front brakes, while ensuring overall braking efficiency.

Title: Cellular silo corner pillar channelled plates - have hooked edges fitting together along sloping laminar contact zones
Inventor: STEFFENS KLAUS GERHARD
IPC: E04H7/30
Filed: 1979-06-28
Abstract: Four gutter-shaped plates have their longitudinal side edge sections bent back opposite ways, over more than 90 degrees, and hooked together on adjacent plates for edge connection, to make up a corner upright support for a cellular silo, or similar. The hooked edge sections (5,6) lie against each other along laminar contact zones (11). Each such zone is inclined against the force line axis at an angle deviating from 90 degrees. Each edge section fitting surface encloses an acute angle with the adjoining plate section (7,8). In each case the force line axis (12) passes through the contact zone. Plates may have thickened edge sections, which can be folded in a U shape and bent opposite ways at less than 45 degrees. This provides improved force transfer in the area of hook connection.

Title: Domestic chimney heat-recovery system - comprises water-filled double-walled plastics pipe acting as heat exchanger
Inventor: HOELTER HEINZ ING GRAD
IPC: F28D21/00
Filed: 1979-08-22
Abstract: The heat-recovery system is designed for use in a domestic chimney. It uses a double-walled plastics pipe made of highly elastic and easily distorted material. The pipe (4) is filled with water, the pressure forming an elastic seal against the chimney and there are water-filled sealing beads (5,6) at the ends, together with inlet and outlet unions for fresh and warm water. The pipe acts as a heat exchanger, forming a lining extending over a portion of the chimney bore. The water keeps the plastics cool enough to avoid damage.

Title: Telephone conference circuit for delta modulated speech signals - sums speech inputs with 100 per cent attenuation for subscriber's own input
Inventor: SCHADE GERD ING GRAD
IPC: H04M3/56
Filed: 1979-08-31
Abstract: The conference circuit comprises a sub unit for sampling the absolute magnitude of each speech input at a given clock rate and converting rising or falling amplitude levels into +1 or 0 digit outputs entered into shift registers and evaluated as to their aggregate incremental step value with the aid of a programmable memory register. The resulting step values, provided with the right sign (aggregate rising or falling trend representation) are applied to a conference incremental value step adding circuit from which emerges one single signal in digitised delta modulation form. Alternatively, to avoid effects from feeding to a participating subscriber his own speech contribution, a further subcircuit is provided from which n different signal outputs derive for then participating subscribers. In the 'Own Signal Subtraction' circuit is provided a signal inversion unit which deducts in the adding units the signal contribution from individual participants. In a supplementary circuit for each of the participants' channels, the instant signal is supplemented by aggregate incremental signals memorized in th e registers and then passed on to delta demodulator units and via low pass filters to the subscriber lines of each participant.

Title: Hydrogen isotope mixture separation process - splits water into currents for exchange with deuterium and protium
Inventor: HUBER MAX DIPL ING DR PHIL
IPC: B01D59/28
Filed: 1979-12-18
Abstract: The process separates a hydrogen isotope mixture into two or more fractions by catalytic exchange between water and gaseous hydrogen, followed by low-temperature rectification of the hydrogen. The water to be prepared is split into two currents, one of which is brought into exchange with a hydrogen current comprising deuterium and tritium, these enriching the water. The other is brought into exchange with a hydrogen current of protium. The two hydrogen currents are by rectification then divided into a fraction consisting of deuterium and tritium and one consisting of protium, and returned as hydrogen currents to the exchange process.
