Title: Inflatable tent made from several interconnected parts - has suitably shaped weighed bead frames supporting canvas and connecting means
Inventor: HAUSHALTER GEORG
IPC: E04H15/20
Filed: 1973-12-12
Abstract: The test is made up of individual elements which each have at least one inflatable shaped bead corresponding to the outline of the sides and roof of the tent.

Title: Wideband reception installation - has non-tunable active antenna, and cable length shorter than eighth of wavelength
Inventor: MEINKE HANS HEINRICH PROF DR
IPC: H04B1/18
Filed: 1973-12-19
Abstract: The frequency band is divided in several channels, and a parallel resonant circuit, tuned to the received channel, is provided at the receiver input. Frequencies are so low, that the cable is at all frequencies shorter than one eighth of a wavelength. The antenna output impedance forms, with the cable output impedance, a band-pass filter whose nominal impedance is real and greater than the cable characteristic impedance. Its pass-band covers the whole signal frequency range. The antenna output impedance is nearly real, nearly independent from frequency and greater than the cable characteristic impedance. The antenna real impedance is so high, that the band-pass filter upper cut-off frequency is only a little above the highest signal frequency.

Title: Video telephone with image displayed on scree - is to allow position setting and is suppressed when viewing documents
Inventor: RAHMIG GUENTHER DIPL ING
IPC: H04N7/14
Filed: 1974-03-05
Abstract: The video telephone enables the user to adjust his position relative to the telephone terminal camera by displaying his own image on his own screen. When the camera is switched over to view documents placed by the terminal, the generation of the user's own image on his own screen is suppressed to allow the document to be viewed. The user's own camera is connected by relay contacts either to the distant terminal video tube or to the user's own. The tube deflection voltage can be switched by further relay contacts. Both relays are operated by push-buttons on the telephone control console.

Title: Flux-less soldering device for terminal wires - has resistance element drawn over molten solder and through hydrogen flames
Inventor: ESPENHAIN MANFRED DIPL PHYS
IPC: H01C1/144
Filed: 1974-06-12

Filed: 1974-10-24
Abstract: The vibratory finishing machine for small components, has a drum around which the finishing medium (4) and the components (5) travel along a helical track (B) and at the discharge point, a flap (3) is lowered so that the components travel across it to a take-off point (8) where they are attracted to a take-off belt behind which is a magnet (13). As they are lifted upwards by the belt magnetically, they pass under successive sets of horizontal bristles (31) which causes the finishing medium to drop off through a channel below for return to the drum. The bristles are carried by a backing member (23) mounted on arms (25) for adjustment.

Title: Heat exchanger with flat parallel cells - cells as elongated irregular hexagons, apertures are at triangular ends
Inventor: KOCH KARL-HEINZ
IPC: F28D9/00
Filed: 1974-10-29
Abstract: Heat exchanger for general and domestic use consists of an arrangement of flat parallel cells with parallel side walls on the narrow sides and with entry and outlet apertures on opposing narrow sides. Each cell viewed from above presents an elongated irregular hexagon shape, with triangular ends. An entry or outlet is arranged on one side of the hexagon at opposing ends of the cells. Preferably deflector plates between individual cell walls form narrow channels which run parallel to those in the adjoining cells and run from entry to outlet in the respective cells. The channels should run parallel to one of the end sides of the cell so as to issue in the second end wall, i.e. side of the end triangle of the hexagon, the system such that apertures serving the same media lie on the same side at each end.

Title: Transistorised high tension ignition system - has two way transformer to feed storage capacitor to energise spark plugs
Inventor: KOPP KAREL DIPL ING
IPC: F02P3/08
Filed: 1975-04-11
Abstract: The storage capacitor is charged from the secondary winding of a transformer by means of a pair of two way rectifiers to produce d.c. The primary windings of the transformer are energized when the transistor is conductive to induce a higher current in the secondary windings which is rectified by the diodes to charge the capacitor in order to store electrical energy. The transistor is regulated by a contactless impulse transmitter which is turned and synchronised in accordance with the running requirements of the engine under all conditions. The ignition circuit can operate when the battery voltage is reduced due to operation of the starter motor.

Title: Seismometer sensing movements along selected axis - has two parts held by springs and generating signal by electromagnetic induction when either is moved
Inventor: FLORIAN EUGENE FRANCIS
IPC: G01V1/18
Filed: 1975-06-13
Abstract: A spring system (47-50) movably holds one part w.r.t. the other in a certain relative position when both parts are at rest. It permits their relative movement owing to the second parts inertia. Second springs (47, 50) limit the first part's lateral movement w.r.t. the selected axis when the firs part is moved. They generate equal and opposite forces opposing the first element's movement along the selected axis. The housing consists of a cylindrical part (10) and a cover (12). The seal is by a ring (13). The lower edge of the housing is bent over the cover at position (14) for firm fixing. A cylindrical centre piece carries a magnet (22) mounted between inner pole pieces (24, 26). A spool mounting (42, 45) holding coils (43, 44) is installed between the pole pieces for electromagnetic induction possibility.

Title: Rotary pump with cooled return of leakage to inlet - has leakage return line duct adjacent to impeller hub
Inventor: RANDELL FORREST THOMSON
IPC: F04D29/42
Filed: 1975-10-21
Abstract: Rotary pump has a return line (11) connecting the housing (2) with the pump inlet (5), through which line leakage is taken from the housing at reduced pressure and returned to the inlet via a cooler, as in 2217292. The return line leads to a duct (22) which enters the pump inlet in a direction with an axial component. The duct may enter immediately adjacent to the impeller hub (8). There may be a chamber (18) upstream of the duct to reduce the velocity of flow of the leakage fluid. This may be an annular chamber surrounding the impeller shaft (4) at the pump inlet end whilst the duct is a conical annular gap.
