Title: Storage tanks of glass reinforced plastic - use panels of GRP sandwiching plastic form for construction
Inventor: BARKOW WERNER OTTO WALTER
IPC: B65D90/02
Filed: 1973-04-03
Abstract: The lightweight, corrosion free tanks are easily built in situ.

Title: Switching device for electronic power controller - has phase shift control device with switching component in series with load
Inventor: HAPPE KARL
IPC: H02M5/257
Filed: 1973-07-14
Abstract: The switching component behaves like a thyristor. The power controller is in the form of an electronic touch switch. It transmits ignition pulses to a triac switching the load. It is connected on one hand to the mains supply, to the triac first anode, through current limiting resistor to its gate and through a series resistor to its second anode and the load. On the other hand it is coupled to a d.c. supply source, also supplying the multi-stage electronic touch switch, which supplies through a resistor a control current to the power controller. Different intensity currents can be selected by stage resistors, controlled by the touch switch whose positions are tripped by very low currents flowing through limiting resistors, contact elements and the operator body.

Title: Hydraulic or pneumatic rotary drive - threads of cylinder, piston and output-gear have twisted polygonal profiles
Inventor: KEMP OTTFRIED
IPC: F15B15/08
Filed: 1973-07-31
Abstract: The hydraulically or pneumatically operated rotary drive has a cylinder, an output gear drive and a piston that is axially movable and operated by a pressure medium. The piston has two threads in opposite directions, one of which interacts with an internal thread of the cylinder and the other with a thread on the output gear drive. These threads are all shaped to have twisted polygonal profile, rounded in cross section. As a result, the rotary drive, which is of simple construction, has a relatively short length, can be used for high pressures and possesses satisfactory tightness, without the need of gaskets.
Patent DE-2347934-A1 (DE)
Title: Ceramic burner for blast heater with narrowed shaft base - with lateral fuel gas intakes, giving increased gas stream speeds
Inventor: MATZKE KLAUS DIPL ING
IPC: C21B9/00
Filed: 1973-09-24
Abstract: A ceramic burner for a blast heater has the lower part of the burner shaft narrowed to a small space through which air flows from below upwards. Gas is introduced into the shaft in a number of small streams through openings at the side of the shaft. The narrowed space increases the gas stream speed and reduces flame pulsation while the gas ports are less likely to get clogged with ash as they are arranged at the side of the shaft. Also good mixing of the fuel gas and air is achieved by dividing the fuel gas stream which reduces turbulence.
Patent DE-2350373-A1 (DE)
Title: Transporting appts. for wood work assembling plants - with lifting device transferring wood from clamping carriage on conveyor belts

IPC: B65G47/04
Filed: 1973-10-08
Abstract: The appts is espec. for plants gluing together rebated wedge ends of lengths of wood and consists of a carriage with movable clamps between which the wood is clamped firmly together. After prior finishing operations the carriage moves the wood in a position between two driven parallel endless belts. In this position the wood which overhangs the carriage above the belts is transferred on the belts after releasing the clamps by a vertically adjustable transferring device positioned between the belts in front of the carriage. The transferring device operated hydraulically has two horizontally projecting arm which engage the bottom of the over-hanging ends and lifts the wood from the carriage to lower it on the belts and taken to a press when the carriage is withdrawn.
Patent DE-2364729-A1 (DE)
Title: Safety guard interlock for press tool operation - A guard operates in parallel with the tool and trips limit switches
Inventor: MENSSEN HEINRICH DIPL ING
IPC: F16P3/02
Filed: 1973-12-27
Abstract: Safety interlock facilities are provided for manufacturing processes where components must be manipulated by hand. A reciprocating press tool member is driven by an hydraulic cylinder to carry out a forming operation on sheet metal components. A safety guard actuated by two cylinders operates parallel to the moving press tool to prevent the possibility of an operators fingers being under the tool. The guard moves a distance such that the access gap is large enough for insertion of components, but too small for finger insertion. In operation the guard moves down and providing there is no obstruction trips limit switches. The limit switch signals then initiate actuation of the tool and completion of this is confirmed by a limit switch to repeat the cycle.

Title: Dish washer using steam in partial vacuum - reduces water volume and ensures silent running with no water circulation
Inventor: WALTER HEINZ G DIPL ING
IPC: A47L15/00
Filed: 1974-05-10
Abstract: The dishwasher operates on the normal cycle with a filter pump etc. and at the end of the rinsing cycle the residual water on the dishes is removed by using suction means. To ensure that no water remains and to speed up the process steam is sprayed into the cleaning chamber which has been partially evacuated by the suction. The hot water and rinsing agent are preferably sprayed into the cleaning chamber where they evaporate in the partial vacuum. The steam produces a very active atmosphere which together with a suitable rinsing agent rapidly cleans the dishes with a reduced amount of water. The machine can be more compact since there is no need for large water collectors. An extra heating element can be provided in the cleaning chamber to accelerate the drying process.

Title: Short wave curtain aerial array of dipole column fed symmetrically - has increased bandwidth wide sweep angle and is matched to supply distribution
Inventor: BRUGER PETER DR ING
IPC: H01Q21/06
Filed: 1974-06-18
Abstract: The array contains a minimum of four horizontally folded dipoles mounted vertically above each other forming a column. The intermediate distance between consecutive dipoles is equal to 0.4 to 0.6 times the wavelength of the mean frequency. Each pair of consecutive dipoles will have a radiation resistance between two given limits. From the supply point of view the dipoles are divided into an upper and a lower interlinked pair. The centres of the two link cables are then linked so that a single feeder at the centre of this second link cable will distribute symmetrically to all four dipoles. The inputs are matched by transformers in the feeder line.

Title: Tubular building frame lattice - has flat bar arch ends with holed flanges for hinged coupling
Inventor: RIBRING LARS
IPC: E04B1/344

The block incorporates a guide-plate (2), set at a sloping angle so that the rocker arm's tension is increased in the process of forward movement. The guide-plate crosses over into a locking surface (4) inclined normal to it, covered with an abutment (5). There may be a spring between a limb (8) of the rocker arm and a block (10) which supports the arm, to press the roller against the run-up block.

Title: Position dependent adaption system for TV image - uses two sync. TV cameras one generating low pass filtered adapting signal
Inventor: OSSENBERG KLAUS DR
IPC: H04N5/235
Filed: 1974-10-04
Abstract: The image adaption system employs two television cameras, which are operated in synchronism and which are directed onto the same image area, via a beam splitting prism. Both the cameras are connected to a common processing circuit and one of the cameras is defocussed and provides the two-dimensional adaption signal, which is passed through a low-pass filter and is used to control the other camera. Preferably the video signal from the defocussed camera is used to control the second camera, so that the video signal from the latter is divided by the adaption signal. The optical system of the second camera may include a light modulator, which is controlled via the video signal from the first camera, or the image converter of the second camera tube controlled by the signal from the signal from the first camera.
