Title: Plastics pipes clamped for butt welding - using two slides with hand operated hydraulic ram and spring compensator
Inventor: DOMMER ARMIN
IPC: B29C65/20
Filed: 1973-06-25
Abstract: An appts. for butt-welding plastic tubes or mouldings etc. comprises two slides on which the components to be welded are clamped; the slides are mounted upon a base frame and can be adjusted relative to each other. The adjustment mechanism comprises a double-acting hydraulic cylinder, operated by a pump and reversing valve; this cylinder is mounted securely on one of the slides and its piston rod engages the other slide by means of spring elements; these spring elements are stressed when the two slides are pulled together. Pref. the hydraulic cylinder is mounted on the stationary slide, and its piston rod is connected to the movable slide. This appts. enables a high holding force to be applied to the welded joint, while at the same time the spring compensation ensures that the fall off in this applied pressure as a result of yielding in the still soft welded material is substantially compensated.

Title: Electronic proximity switch with approach controlled oscillator - uses switching thyristor and only two external leads to source and load
Inventor: GEHL WILFRIED DIPL-ING
IPC: H03K17/945
Filed: 1973-07-21
Abstract: The electronic proximity switch has an oscillator whose frequency is altered by the approach of the operator finger etc. The oscillator is coupled over a transistor to a thyristor switch. The thyristor is coupled to a diode bridge rectifier. If a triac is used instead of a thyristor, the diode bridge is not needed. The bridge inputs are connected to only two external terminals. The source and load are coupled in series between these inputs. One of the circuit two supply points is earthed over a high impedance series combination of a resistor and a diode. To complete the circuit, the junction between load and source is also earthed, thus employing only two external connections.

Title: Stepping feed for punched cards - a continuously rotating shaft motion is converted into an incremental stepping action using a pivoted roller follower
Inventor: BERGER HELMUT
IPC: F16H35/02
Filed: 1973-09-18
Abstract: Punched hole data cards are fed in a step-by-step mode by drive rollers mounted on a shaft . A continuously rotating drive wheel carries a bearing mounted cam follower that is free to pivot about a centre pin. The cam follower has a projecting arm that is spring loaded into contact with a bracket mounted drive roller for output shaft motion. The drive roller assembly is clamped to the output shaft. The multi-lobe cam is rigidly fixed to a m ain structure plate. When the input shaft rotates the arm of the cam follower oscillates about the support pin and step-by-step indexing of the output shaft occurs, with the drive rollers transmitting a similar motion to the data card.
Patent DE-2350657-A1 (DE)
Title: Former for iron cored transformer - has built on fixings for laminations and flexible projections on inner faces
Inventor: KOEHLER GERHARD
IPC: H01F5/02
Filed: 1973-10-09
Abstract: A former for an iron cored inductance which reduces the effect of vibrations and prevents the laminations from shifting out of position. This is done without additional components by having a fixed projection on each of two adjacent inner faces of the rectangular section bobbin. The projections are flexible and are used to clamp the sides of the iron core. They can be either parallel to the longitudinal axis or run along a diagonal of the face. When the laminations are fitted on to the former, the projections are bent sideways, making use of their flexibility, which is then used as a spring loading to hold them in position.

Title: Door for tunnel type access chamber - has hinged bearings which withstand pressure acting on doors
Inventor: KUHN ROLF
IPC: E05D3/02
Filed: 1973-11-02
Abstract: This door is used as a protection door against high outside pressures. The door is pressed against its frame for sealing purposes and it can be rotated about its hinge bearings outwards. In order to prevent damage to the door hinge bearings by the pressure force acting on the door, the components of the hinge bearings, which connect the door panel to the door frame, are able to slide in the direction of the tunnel axis. The door panel consists of an outwards bulging outer shell and a flat inner panel. This composite door panel is connected by means of bearings with the door frame. The door is actuated by means of the drive located in the wall of the tunnel. In closed state a closing wedge is held so that its outwards facing inclined surface is in contact with the catch and the inner flat side has a clearance with the catch. Vertical play is eliminated in the hinge bearing and the door weight is supported by a bearing mounted on the floor. The door is pressed against the door frame without affecting the hinge bearings because there is sufficient play in the direction at right angles to the door panel.

Patent DE-2403114-A1 (DE)
Title: Choke as non-linear storage element in converter - supplies variable load and has core made from stacked stampings
Inventor: EMMRICH PETER
IPC: H01F38/02
Filed: 1974-01-23
Abstract: Choke used as a non-linear storage element, made with a pattern of airgaps in the core. It is incorporated into a converter circuit acting as a standby when there is a mains cut out and the supply is switched over to a battery source. If the load drawn under these conditions fluctuates then the requirements for the coil are contradictory. The winding cross section and magnetic clipping of the core must be designed for the maximum load and on the other hand, the inductance has to be large enough that the product of current and self inductance coefficient is greater than zero. The stampings when stacked to form the three limbs can have unsymmetric halves to produce stepped airgaps or similar patterns.
Patent DE-2408420-A1 (DE)
Title: Flexible framed panel-cladded partition wall - sprung between uprights and ceiling bar, with panel allowing maximum oscillation amplitudes
Inventor: ZIMMERMANN HANS
IPC: F24D3/14
Filed: 1974-02-21
Abstract: The object provides at low cost, esp. in residential buildings, an effectively top and bottom sealed partition wall with a rigid frame and which allows effectively for ceiling and/or floor oscillations. It comprises cross bars supported against floor and ceiling, upright bars between these, and one or more frontal cladding panels. Durably elastic spring media are fitted between the uprights and at least the ceiling cross bar, and the panel height is reduced by an amount corresponding to the maximal extent of floor and/or, ceiling oscillation amplitudes, and is fixed so as to allow vertical movement relative to the oscillation-loaded cross bar. The spring force of the elastic media is pref. adjustable, with the spring elements seated in grooves in the bars or panels. There may be elastically compressible sound-absorbent panels between the uprights.

Title: Ignition circuit for electronic flash-lamp - has series thyristor in series with lamp and ignition capacitor
Inventor: DIETRICH ROLF DIPL ING
IPC: H05B41/32
Filed: 1974-09-25
Abstract: The ignition capacitor is connected through a switching thyristor to an ignition transformer in an ignition circuit. Ignition circuit (1, 2, 3 101, 102) connection (101, 9, 60) with series thyristor (6) control electrode (60) is made by an electronic threshold switch (7), whose control electrode is connected to a switching circuit (5, 71, 7) whose terminal voltage is changed by the flash-lamp current. The threshold switch (7) threshold is such, that it becomes conducting for a specified time interval when the current reaches the locking value. The advantage lies in the condition that the control power for regulation of the series thyristor is first used when the plasma of the flash lamp is sufficient for assured ignition of both lamp and thyristor.
