Patent DE-2134076-A1 (DE)
Title: Long-tapered tubes prodn using short mandrel
Inventor: CRESS HOBART ALEY
IPC: B21C37/16
Filed: 1971-07-08
Abstract: Tapering of tube by drawing through a die over a tapered mandrel, the die being deformable and the mandrel being moved relative to the tube at a slower speed than the drawing speed such that the tube tapers to a different length than that of the mandrel. The mandrel possesses the desired maximum and minimum diameters for the finished tube inside diameter but may be short relative to the length of taper required in the tube.

Title: Debris grating/rake assembly - for use with clarification tanks based on prefabricated concrete components
Inventor: SCHNITZSPAN HANS GUENTER
IPC: E02B8/02
Filed: 1971-07-27
Abstract: The foul water or storm water drain has immediately upstream of the grating a deep central channel with widened side channels relatively shallower and divided from the central channel by overflow weirs whose height is that of the max. permissible water level in the channel. The ends of the grating section are closed by separated wall sections to prevent flooding from those ends where the inlet and rainage channels join it. The appts. gives automatic relief in the event of blockage of the grating esp. due to failure of automatic clearing gear or failure to carry out maintenance where cleaing machine is not permanently installed.

Title: Nuclear - elect. energy direct conversion electron tube - having neodymium anode, carbon cathode and lithium insert, without nuclear transformation
Inventor: MARKERT KURT
IPC: G21H1/04
Filed: 1973-04-09
Abstract: Electron tube of lower pressure polymsn. polyethylene is 100cm. long, 1 cm wall thickness and 3 cm i.d. Before the electrodes are fixed in place, a 6Li rod is inserted under vacuum to within 10 cm. of the Nd anode. The sealed tube is inserted along a horizontal channel into an experimental reactor of max. neutron flux 1.8 x 10 14n/cm2 sec., for an irradiation time 4 sec. The irradiation of 6Li produces tritium which by radioactive decay and reformation of the orthopara hydrogen cycle maintains the electron activity. The primary effect resulting is the rhythmic triton nuclear oscillation between 144Nd60 and 147Pm61 without nuclear conversion, giving direct nuclear-electrical energy conversion. A secondary effect abserved in the imission of beta-rays by radioactive compensation of the triton nuclear oscillation.

There is also a thin, side frame strip of metal or plastic with an angled side edge for holding and this is vertically presed. The plate is then fixed on the cover.
Patent DE-2349283-A1 (DE)
Title: Direct contact condenser for steam power stations - has sparge pipes with injection nozzles for cooling water
Inventor: STRAKATA JOSEF
IPC: F28B3/04
Filed: 1973-10-01
Abstract: The condenser has a vertical cylindrical metal casing with a steam inlet central in the base directing steam upwards. A cooling water inlet pipe runs vertically down the centre of the shell from the top. It carries a series of sparge pipes running out horizontally from it and spaced at equal intervals vertically from each other. Each sparge pipe contains a number of injection nozzles which atomise the cooling water and spray a cloud of small droplets in counter current to the upflow of steam. These clouds have a large surface area dn therefore achieve rapid cooling and condensation of the steam in a small volume thus reducing the space taken by the condenser. The same construction can be used for water coolers.
Patent DE-2352430-A1 (DE)
Title: Terminal connector for tubular conductor with tolerance - utilises elasticity of clamping material acting as jaws
Inventor: MOECKS LOTAR
IPC: H01R4/60
Filed: 1973-10-19
Abstract: Terminal connector for cable with tubular conductor which makes allowance for the variation in tolerance to insure trouble free and safe contact. The clamping effect is achieved by the deformation of the conductor and or the terminal due to the elasticity of the materials. The terminal consists of a lower and separate upper part which surrounds the tubular conductor like jaws. The lower section has a U shaped cross section with sloping vertical walls which form the major areas of contact with the conductor. The upper section fits over the channel like a cover which also makes contact with the conductor and is compressed against it.

Title: Bolt-setter positioner and actuator - has receiver frame with two actuators, engaging bushing and releaser respectively
Inventor: SEYBOLD ROLF PROF DR ING
IPC: B25C1/18
Filed: 1974-01-05
Abstract: Actuator is for a bolt-setter. Before release for setting a bolt, the annular end face of a bushing surrounding its mouthpiece and displaceable against the force of a spring in the apparatus against the setting direction, is to be set on the point where the bolt is to be set, and the apparatus is displaceable, with a force exceeding the weight of the bolt-setter, relative to the bushing. A receiver frame for the bolt-setter has a holding rod attached to it, with 2 actuating levers of actuators leading to the frame; one of the actuators engages the bushing opposite to the direction of setting, and hence is displaceable relative to the bolt-setter, while the other engages the releaser of the bolt-setter. Different bolt-setters can be used with the apparatus, and can be accurately positioned, with retention of safety by maintenance of the pressing force.

Title: Simple quiet limited output digital printing mechanism - prints typically six digits rows using reciprocating mechanism with pressure roll
Inventor: REINHARD WALTER
IPC: G06M3/06
Filed: 1974-05-18
Abstract: The numbers are arranged round the circumference of counter wheels. In addition to the numbers for printing, these wheels carry display numbers which can be examined visually through a suitable window. Underneath the wheels, a paper band is fed through the mechanism and underneath this, in turn is mounted a pressure roll and its associated mechanism. When this is actuated, the mechanism moves along and upwards to press the paper against the print characters on the counter wheels. The device is simple and inexpensive, and quiet in operation since there is no hammer action.

Title: Positioning arrgmt for indication and/or control - used for reference face of grinding machines grinding two surfaces
Inventor: LANKES KARL
IPC: B24B49/04
Filed: 1974-06-08
Abstract: The grinding machine consists of two wheels (2, 3) which are mounted concentrically on a vertical centreline. Workpieces which are mounted in holes in a rotating disc are fed between the sides of the two wheels which face one another. On the inlet side, the workpieces are supported on a table, the surface of which is level with the grinding surface of the bottom wheel. The surface of this table forms the reference face. At the point where the workpieces leave the grinding wheels, they pass between an upper (8) and lower (9) measuring probe. The combinec output of these probes is fed to a control arrangement which feeds control signals alternately to the position control motor of upper and lower grinding wheel. A third probe measures the position of the bottom grinding surface and ensures via the control arrangement that this surface remains in line with the reference face.

Title: Window raiser for door assemblies in vehicles - has arm in two sections with relative position changed by excess load through rack and pawl
Inventor: KLUETING BERND
IPC: E05F11/38
Filed: 1974-09-14
Abstract: Car door window raiser arm with gear drive is divided into two sections held in pre-set relationship until a set load is exceeded, thus causing the sections to move relative to one another. The sections are held in their pre-set relationship by a spring. One section has a detent which locks onto a rack when the arm sections move in relation to one another. The detent should be capable of adjusting along the arm and coupled to the other section to control this after the relative movement. The detent can take the form of a pivotal pawl, in which case the rack should be a bow design.
