Title: Oscillating cct for telephone enne exchanges - with resonance transfer by connection of two series capacitors to AC generator
Inventor: HEYLAND ULRICH DIPL ING
IPC: H03H5/00
Filed: 1974-07-03
Abstract: Two series capacitors are part of an oscillating circuit. A switch controlled by the generator output voltage phase is inserted into the oscillating circuit. When the switch is off, the capacitors are charged to the peak of the oscillating circuit voltage. The switch is so connected in series with the oscillating circuit inductance, that the capacitor is connected to the a.c. voltage generator output even when the switch is off. The switch is conducting in one direction only, and is shunted by a diode conducting in the other direction. The switch is realised in the form of a transistor.

Title: Articulated earth mover - with removable tracks on pneumatic tyres and with forward control cab
Inventor: KORTENDIEK ALBINUS
IPC: E02F9/00
Filed: 1974-07-18
Abstract: The earth mover has two sections (2, 3) joined by an articulated steering link (10) operated by hydraulic rams. The separate sections are each supported on two axles (6) which are mounted at the ends of support arms linked by a common transverse axle (4). The support arms are splayed apart by rams (19) to change the wheel base and to secure a track over the pneumatic tyres. The track has grip elements held together by wire ropes and fits snugly over the tyre tread. The front section supports the driving position and the scraper blade (27) while the rear section holds the engine (22) and a hydraulically operated shovel (68). The vehicle can operate on soft ground with the tracks can travel on normal roads with its pneumatic wheels, so that it requires no special transporter. The forward driving position gives the driver more control over the work.

Title: Up-and-over door - opening assisted by set of compression springs acting on cantilever part of leverage
Inventor: KAEUFERLE JOSEF
IPC: E05F1/10
Filed: 1974-08-05
Abstract: Although the present design retains the customary principle of an assisting pulling action applied on the cantilever part of a leverage, this pulling action is transmitted from a compression spring (10) fitted around a rod (9) which is fixed to the door frame (1). To the lower part of the spring a pivoting sheath (19), acting at the same time as a draw bar between the lower part of the compression spring and the joint (15) of the cantilever, is provided. The tension of the compression spring is adjustable by a nut (17). This design prevents danger of injury to the user caused by touching the spring while it contracts during the opening action of the door.

Title: Gear change-over mechanism for start-stop roller counter - has pinions to transmit movement from one digit roller to another
Inventor: ENGELMANN RICHARD
IPC: G06M1/16
Filed: 1974-08-07
Abstract: The gear profile of the teeth (e.g. 16) of the pinions (5, 6, 7) which have the smaller axial length is such that it interacts with the teeth of the driven rollers (e.g. 3) with as small a backlash as possible. The profile of the remaining teeth of the pinions is so designed, at least in the axial region where they interact with the cylindrical generated surface of the driven roller (e.g.2) as blocking elements, that their points of contact with this generated surface are as far removed as possible from the axis of rotation (8) of the pinions. The gear mechanism is intended especially for charge counters in telecommunication systems.

Title: Lock with flat key and rotating insert - has radially moving locking elements and notched guide for stabilisation
Inventor: MERKLE PAUL
IPC: E05B27/00
Filed: 1975-02-25
Abstract: The flat key lock with rotating lock insert has a number of series arranged radial, sliding tumblers which are guided in the lock sleeve. A locking lever pivots about a pin and it is loaded by a tension spring which attempts to move a locking element radially inwards. A guide plate has rectangular or trapezoidal notches for locking levers. When the locking element moves inadvertently outwards radially then the guide plate establishes a contact with it because of the narrowness of the notches. The above tension spring during the final anti-clockwise movement of the locking element urges the locking lever downwards over a bevelled edge.

Title: Damping circuit for mechanical oscillations of piezoelectric elements - allows fast amplitude adjustment by counteracting signal producing oscillations
Inventor: PETERSEN AUGUST DIPL PHYS
IPC: H01L41/04
Filed: 1975-04-23
Abstract: The electrical damping circuit, for damping the mechanical oscillations of piezoelectric elements, allows rapid adjustment to any required amplitude by forming an electrical signal that acts against the signal causing the oscillations. The counteracting signal may be a pulse voltage superimposed on the deflecting voltage, or a negative feedback voltage derived from the deflection rate. The feedback voltage is obtained by connecting the piezoelectric element into an RC bridge (5-8) whose one diagonal is coupled to the inputs of a diff. amplifier. The amplifier's output is combined with the pulses (10), amplified (11) and applied to the element (5).

Title: Flap wing type wind motor - has wing swivelling around horizontal axis is fitted at end of rocking arm
Inventor: BADE PETER DIPL ING
IPC: F03D5/06
Filed: 1975-05-30
Abstract: Wind motor producing linear driving movement, consists of a rocking arm performing swinging movements around horizontal pivot. The shorter arm is fitted with counterweight and connected to a push rod at the end of which the pump piston or a linear current generator are fitted. The longer arm carries at the end one or several flapping wings swivelling around a horizontal axis. The flapping movements of the wing are limited by stops with built-in shock absorbers. The wind attacking produces a component which moves the rocking arm from one terminal position to the other. At the same time the position of the wing changes and the wind now attacks the opposite surface of the wing, producing a component which now moves the rocking arm in opposite direction. The horizontal swivelling axis at the end of the rocking arm is located downstream beyond the point of attack of the resultant wing lifting forces.

Title: Light structure industrial hangar block skeleton system - with frame corners given rigidity by highly rigid prestressed screws
Inventor: GALGOCZY GABOR DR
IPC: E04H5/02
Filed: 1975-11-06
Abstract: The skeleton system is for a light structure industrial hanger-type block, and has a frame with corner-rigid connections provided by the use of prestressed screws, producing a high degree of load bearing capacity in the line of the screw axis, to absorb the axial norm forces. The prestressing of the screws leads to enhanced friction between the contact surfaces of the elements being connected, suitable for absorbing the shear forces vertical to the frame axis. The surfaces of the elements being connected are joined as paired forces for absorption of the pressure force components of the corner moments. The nodal points corresponding to the tension cross-sections of the connecting elements absorbing the forces, and to the homogenously assumed cross-section of the pressure surfaces of the elements being connected, contain a reduced proportion of screws. The intrinsic weight of the frame is reduced, and material is saved.

Title: Stable aq. dispersions of pigments - mixed with aq. alkali silicates to form paints
Inventor: SCHWIETE ROLF DR
IPC: C09D1/02
Filed: 1976-02-06
Abstract: Two-component silicate paint materials consists of (a) an aq. dispersion of pigments with (b) aq. alkali silicates. The materials pref. contain wetting agents, e.g. alkali- or ammonium- phosphates, esp. poly- or pyro-phosphates, or mixts. of these agents, esp. using by wt. 0-3%, partic. 0-1% of the agents. They also contain dispersants, e.g. NH3 or its derivs., esp. using 0-3% partic. 0-1% dispersant. They opt. contain thickeners, e.g. montmorillonite, esp. at 0-1% thickener. The conventional silicate materials are not stable and coagulate; and therefore dry pigments are often mixed on site with alkali silicates; but this does not produce uniform suspensions and poor paint finishes are obtd. The invention produces an aq. pigment dispersion which can be stored for unlimited periods.

Title: Demonstration of mutual force of attraction between masses - uses continuous chain loop driven at high speed with parallel section with small gap
Inventor: GROSSMANN FRANZ-KARL DIPL ING
IPC: G09B23/10
Filed: 1976-03-13
Abstract: An experimental rig is used to demonstrate the existence of forces of mutual attraction (repulsion) between moving bodies. Since the mass of most bodies is small the forces may only be apparent if the velocities are extremely high. Also if two bodies pass each other at high velocity the forces will only exist as short duration transients. The rig adopted is used in a continuous chain loop (1), fed over two rollers (2, 3) and with guide rollers (3). The chains are in close proximity over a parallel section (script l) and are travelling in opposite directions to generate a lateral force of repulsion. Typically the distance between the chains is 55 mm, with a mass of 2.7 kg/m.

Title: Rotary piston combustion engine - has pivoting sealing strip mounts and sickle shaped combustion chambers
Inventor: GOEGLER PAUL
IPC: F01C21/10
Filed: 1976-03-19
Abstract: The inner surface of the housing (12) consists of two symmetrical cylindrical surfaces, the radii of which are approximately equal to the radius of the rotating piston (22). These surfaces are joined by two other cylindrical surfaces (34, 36) with smaller radius and with the centrelines (48, 49) so positioned that an oval is formed. The shape of the cylinder is such that two sickle shaped combustion chambers (52, 54) are formed. The suction inlet (60) is located at the beginning of one of the chambers, while the sparkplug (72) is mounted at the start of the other chamber. The rotor has wedge shaped cut-outs (26) around its circumference in which segments (28) are mounted. The segments can pivot in the cut-outs, the movement is controlled by a pin which runs in a groove (78). By the movement of the segmens, sealing rims (86) which are mounted on the segment, are kept in contact with the cylinder surface, thus sealing off the combustion chambers.
Patent DE-2612548-A1 (DE)
Inventor: BROMME IRMFRIED DIPL ING
IPC: H01H47/22
Filed: 1976-03-24
Abstract: The push-pull output amplifier (A1/A2) which has a tristate output (Q) has two series-connected, separately controllable push-pull transistors (T20, T23). The permissible tolerance, e.g. from 6.8 volts to 36 volts, of the DC supply voltage (US1/US2) of this driver component is particularly broad, although output currents with narrow tolerances occur at the component output (Q), since each of the two push-pull transistors (T20, T23) is activated via a constant current source (S1/S2) which is connected to supply current only when the relevant push-pull transistor (T20 or T23) which is activated by it is switched to its conducting state. The driver component can be used in systems with virtually any, very different, DC supply voltages, in particular to control relays which have a precisely defined response threshold. <IMAGE>
