Title: Venturi scrubber for gas cleaning - has compact design especially suitable for use in mines
Inventor: HOELTER HEINZ
IPC: B01D47/10
Filed: 1975-11-29
Abstract: The scrubber has an inlet passage for the waste gas located upstream from a multi-stage spiral venturi which has sepn. slots controlled by pref. adjustable plates. The central outlet passage has a diffuser shaped connection to the outlet from the venturi-stage. A dividing plate guides the water sepd. in the venturi to a sump. The water is recycled from the sump, pref. via hydrocyclones by a pump to the spray nozzles at the junction between the inlet passage and venturi. Make-up water is introduced through a float-controlled valve in sump. The gas entering the scrubber is deflected from its axial direction of flow by a series of deflector baffles which distribute the gas uniformly in circumferential flow at the venturi inlet.

Title: Chromium coated copper foil cutters formed by electrodeposition - for use as the cutting elements of an electric razor
IPC: B26B19/38
Filed: 1976-01-09
Abstract: In an electric razor the cutter foils, which are rotated against each other, are formed by electrodeposition of a Cr layer on a Cu support on at least the cutting face. The Cu support has a hardness of 200-500 Vickers (300-450 Vickers) and the Cr electrodeposit a thickness of 0.3-5 (1.5-3) mu with hardness 600-1700 Vickers on the cutting face. The Cr electrodeposit on the side which face the skin has a lower hardness of 400-800 Vickers. The Cu foil support is formed by electrodeposition from an electrolyte contg. Cu (I) and (Cu(II) ions, having a very high metal density. The method eliminates the use of S contg. Ni electrolyte which is slow acting and costly.

Title: Submersible vertical centrifugal pump - has blades within cylindrical rotor with circular outer cross section
IPC: F04D29/04
Filed: 1976-02-24
Abstract: Pump has a cylindrical casing (14) which is submerged in a tank or similar container. A vertical shaft (21) through the centre of the casing carries an impeller (20) on its end. The impeller has an inner core (28) with a hemi-spherical surface (29) to which centrifugal blades (26) are attached. The blades are surrounded by an outer rotor section (31) which has an inner surface fitting to the blades and an outer surface in the form of a cylinder which fits inside the cylindrical casing with a small annular gap between them. This enables the pump to have a centrifugal impeller inside a plain cylindrical casing so that it can produce a high head without needing an elaborate shaped casing.

Title: Railway vehicle emergency braking device - comprising plastics cable with anchor locking into trackside notches when unrolled
Inventor: MAATJE HENRI DIPL ING
IPC: B61H11/00
Filed: 1976-03-20
Abstract: Each vehicle is fitted with an anchor device which can lock into notching devices beside the track rails when stopping is necessary. The anchor is connected to the vehicle by a cable rolled up on the vehicle. Activation of a braking device, mounted on the vehicle and protected from weather effects, causes this to unroll, using so much energy that the vehicle comes to a standstill before the whole length of the cable has been drawn out. The cable can be rolled up on a drum in a vehicle, with disc brakes fitted to it. The cable can be made of polyamide or an elastomeric material. It may be in strip or chain form. Braking distance is independent of weather conditions or rail condition, and the brake is very rapidly effective.

Title: Sliding cupboard door lock - has groove on underside of sliding latch engaged by pivot arm when locked
Inventor: HEINEMANN KARL
IPC: E01F13/06
Filed: 1976-04-26
Abstract: The door lock suitable for a sliding cupboard door can be positioned so that the locking bolt (7) can be pushed into a hole in the interior face of the door. A recess (12) on the underside of the bolt (7) is engaged by a spring loaded latch arm (16).

Title: Tert.-amines prepd. from prim. or sec. amines and alcohols - with a hydrogenation-dehydrogenation catalyst and stoichiometric amt. of alcohol
Inventor: HOFFMANN HERWIG DIPL CHEM DR
Filed: 1976-06-04
Abstract: Prepn. of mono- or poly-, symmetrical or asymmetrical tert-amines comprises reacting a prim. or sec. amine R1-NH-R2 (where R1 and R2 are each H, alkyl or cycloalkyl gps., opt. substd. by inert substs. which, in turn, may carry amino gps. -NHR1) with mono- or di-hydric prim. or sec. - alcohols. The reaction is catalysed by a hydrogenation/dehydrogenation catalyst, opt. in the presence of H2, and the amine is fed into the liq. reaction mixt. contg. the mixt. of alcohol required for the reaction and the proportion of water formed in the reaction is eliminated. High yields of tert-amines are obtd. with low amts. of prim- and sec-amine contamination. Since the alcohol reactant is completely consumed the sepn. of alcohol from tert-amine, which is usually difficult and energy-consuming, is avoided.
Patent DE-2627303-A1 (DE)
Title: Electromechanical load cell transducer system - has long term null point stability from twin opposed strain gauge elements
Inventor: KUHNLE ERNST DIPL ING
IPC: G01D5/16
Filed: 1976-06-18
Abstract: The electro-mechanical load cell transducer system uses two sets of strain-gauge elements whose output signals, in the unloaded condition, are equal and opposite. This arrangement provides long-term stability of the null point since any physical changes, e.g. temp affect both sets of elements equally. Two sets of Wheatstone Bridge-connected strain-gauge strips are held under tension on the same steel band by a spring (A-B) (7-9). A horizontal, counterbalanced beam (5, 10) is connected to the vertical band mid-way between the elements. In the unloaded, balanced mode, there is no electrical output from the combined transducers. When the beam is loaded (11), the unequal loading on the transducers produces an output signal proportional to the load.

Title: Cocoa butter processing device - with slotted and twisted discs on cylinder for fine uniform distribution of enclosed air
Inventor: SOLLICH HELMUT
IPC: A23G1/00
Filed: 1976-11-22
Abstract: Cocoa butter and similar fatty substances in chocolate manufacture are not freed from the air which has entered it in the processing stages but the air is so finely and uniformly distributed that it cannot be seen by the human eye. The device has a cylindric housing holding in flanges with eyes and a rod on which alternately bushes and discs are stacked. Each disc has four radial slots and the sectors between them are twisted. Provides reliable and economical method of retaining the same attractive appearance as when all the air has been removed, which is extremely difficult in the case of very viscous masses as used for coating filled chocolate.

Title: Muting arrangement for telephone dialling tone - is based on switch operated by handset which disconnects alarm when handset is lifted
Inventor: FORDAN GUENTER DIPL ING
IPC: H04M1/26
Filed: 1977-07-26
Abstract: The telephone set includes a changeover switch (GU) with poles (S1, Si) to switch an acoustic transducer (Lsp) on and off.

Title: Electronic relay for balanced loading of three=phase network - uses phase load current to control duty factor of multivibrator
Inventor: STEINMUELLER GUENTER
IPC: H02H3/42
Filed: 1977-10-24
Abstract: The electronic 3-phase relay, for balanced loading of a 3-phase network, has a shunt (1) in one phase (R). This shunt is used to obtain a voltage proportional to the load current in this phase. This proportional voltage is amplified and used to control the duty factor of an astable multivibrator (8).
