Patent DE-2531014-A1 (DE)
Title: Removing radioactive noble gases from carrier gas - by passing through adsorbent bed of large cross section as a number of separate streams
Inventor: WINTER KARL DIPL PHYS
IPC: B01D53/02
Filed: 1975-07-11
Abstract: A method of adsorbing gaseous or vaporised impurities from a flow of carrier gas onto granular adsorbent consists of projecting the carrier gas as numerous small free gas streams into the space above the adsorber bed, so that it is distributed uniformly across the cross-section of the bed. The cross-sectional area of the bed (2) is 1,000-100,000 times the cross-section of the incoming gas flow. Before being subdivided into small streams, the carrier gas may be cooled and/or dried. Used esp. for adsorbing radioactive noble gases onto activated carbon. Also for removing mercury vapour. The slow speed of flow through the bed increases the tendency of the impurities to precipitate, as a result of the increase in the delaying effect on the atoms of noble gases. For a given, large volume of bed, the pressure drop is considerably reduced, by comparison with a long slender bed.

Title: Arc welding electrode position control - by deviating arc magnetically and measuring the arc length
Inventor: PUSCHNER PETER DR ING
IPC: B23K9/127
Filed: 1975-10-20
Abstract: The position of an electrode holder is adjusted w.r.t. a joint between two workpieces which are to be welded together. At least two characteristic quantities of the arc parameters are derived from the arco burning between the electrode holder and different regions of the sides of the joint. The characteristic quantities are mathematically coordinated and the result is compared with a control value which corresponds to the desired position of the electrode holder, and a control margin, which corresponds to the difference between the result of the calculation and the control value is used to position the electrode holder. The welding arc itself acts as a sensor determining the relative position between the electrode holder and the joint.

Title: Regenerative braking vehicle hybrid transmission - has surplus energy stored in flywheel and coupled to drive by reduction gearing
Inventor: HELLING JUERGEN PROF DR ING
IPC: B60L50/30
Filed: 1975-12-02
Abstract: The hydrid transmission has a low output drive motor which runs at a set level. Surplus energy is stored in a flywheel, with the stored energy equal to the amount required to drive the vehicle at max. speed. The improved torque is taken to the driving wheels by a reduction gearing from the flywheel and by a hydraulic or electric link between the engine and the wheels. The hydraulic or electric link has a storage capacity of either a battery or a pressure reservoir so that it can also provide energy for sudden peak torque demands such as for starting up hills. The total weight of the transmission is reduced and simplified.

Both mats are then stitched over with large stitches, so that the two mat parts form a compact yet flexible unit. Nylon thread is incorporated for reinforcing banks. The seed mats are laid over previously rolled ground and anchored with pegs, then covered with earth, and rolled again.

Title: Support or scaffolding construction system - has column components with clamps at ends for transverse tube sections
Inventor: LOEWE HENRI
IPC: E04G1/06

Title: Power operated lathe tailstock - has spring loaded centre operating motor cut out when pushed against work
Inventor: DOZEKAL ERICH DIPL ING
IPC: B23B23/00
Filed: 1976-09-10
Abstract: The power operated lathe tailstock (1) has an electric motor (6) mounted one end, with a worm drive (7) on its output shaft driving a pinion (9) which engages a rack (8) between the guides of the bed, to advance the tailstock. When the centre (4) engages the work (3) the holder (5) carrying the centre is pushed back against a spring (10) so that a switch arm is moved, to stop the motor. In an alternative design, a motor mounted on a fixed pedestal moves the tailstock by means of a nut and spindle drive. The cut-out operates in the same way. Another similar design has a hydraulically operated piston instead of a nut and spindle drive.

Title: Continuous chain transporter for carriages - has ramps used as decoupling mechanisms permitting slowing down of carriages
Inventor: HAURIN JEAN-MARIE
IPC: B61J3/08
Filed: 1976-11-10
Abstract: The mechanism is used for slowing down the movement of transport systems and is equipped with transporter chains and coupling mechanisms. The coupling mechanisms are connected with corresponding stops on the carriages (7) to be transported. The travelling speed is reduced in the given regions for ensuring longer handling time of the objects carried on the carriage. No additional special actuating mechanism is used in these areas. In the region of slow travel there are several sloping ramps designed as decoupling mechanisms. These ramps are arranged at uniform distances from each other along the track. They can be rotated about a vertical axis and they are connected to each other with levers. The first ramp is connected with an actuator and the ramps are pivoted in succession from their basic position into action position and back.

Title: IC engine vacuum value signal system - has vacuum sensitive cylinder held in induction manifold by air filter tensioning bolt
Inventor: HATZ ERNST DIPL ING
IPC: F02M35/09
Filed: 1976-11-10
Abstract: The air filter cartridge tensioning bolt (22) is hollow in order to contain a plastic rod (34). The upper end of the rod carries a red display cap (34a) which lies just below an opening in the filter cover plate (32) and on top of the tensioning bolt locking nut (226). The tensioning bolt is surrounded by a cylinder (36) containing a sprung piston (38). The spring side of the piston is subject to manifold depression via openings (42a) in the cylinder top (42). The opposite side of the piston is subject to atmospheric pressure. The piston has a permanent magnet (44) to work with a metal ring (46) surrounding the plastic rod (34). When the depression value sinks owing to a dirty filter cartridge, atmospheric pressure causes the piston to rise and bring the display rod with it. The display rod could have a projection (34a) at its lower end to complete an electrical circuit for an audible display unit.

Title: Signalling during connection build up in telephone pbx - switching state criteria are transmitted in addition to dialling signals, and evaluated at receiving exchange
Inventor: LOICHINGER JOHANN ING GRAD
IPC: H04M7/14
Filed: 1976-12-10
Abstract: Traffic concerning connections through tie lines and to the exchange passes through an allocated main unit. Additional criteria concerning different switching states are transmitted to the opposite exchange in addition to the dialling signals. When a free connection line translation is engaged by directional dialling, at first an engagement signal is tranmsitted, and then additional criteria concerning the calling extension entitlement and/or the type of connection and/or the required traffic directions. They are transmitted over the connection line in the same way as dialling signals to the same type corresponding dialling signal receivers. The engagement signal in the receiving translation connects a central dialling signal evaluation device, and the additional criteria are applied to the central evaluation device, there converted and evaluated, and then the required connection is either blocked or permitted. The required traffic direction is then marked and a free line found in the corresp. group lines.
