Title: Drive esp. for rudder propeller with concentric shafts - has outer shaft with special arrangement of conical roller bearings
Inventor: EICHINGER JOHANN
IPC: B63H23/04
Filed: 1975-07-25
Abstract: In a rudder propeller drive for water craft the horizontal propeller shaft is contained in a housing and can pivot about a vertical axis.

Title: Current circuit switch for toy train systems - is operated by tongue spring switches at intervals reducing need for transformer power
Inventor: KILIAN HELMUT
IPC: A63H19/24
Filed: 1975-08-01
Abstract: The current circuit switch for several stationary fittings using about an equal amount of current (such a bulbs, spools of switch magnets etc.) forms part of toy train installations. The current circuit switch consists of an electromagnetically operated switch, the anchor shaft of which comb shaped, so that the keels of the comb each control one tongue spring switch (2, 3, 4, 5, 6, 7) each of which lies in the circuit of one or more current user fittings. This ensures that during operation of the switch the tongue spring switches are switched on or off one after the other which, despite the small intervals permits the use of a smaller capacity transformer reducing the cost.
Patent DE-2545762-A1 (DE)
Title: Flexible hollow body made of plastic films - with cavity for drainage, heat insulation, or buffer layer in package
Inventor: ROSEMEIER HEINRICH WILLI DIPL
IPC: B32B3/28
Filed: 1975-10-13
Abstract: Flexible hollow body is made from plastic films with spacing indentations which are (partially) connected to each other. One or more of the plastic films also have undulating indentations which extend linearly in >=1 direction and which render the plastic films expansible. The flexible hollow body may be connected to other expansible or flexible materials. The sec. indentations have a concertina-like function so that on expansion or compression of the film, not the expansibility, but only the flexibility of the film material is effected. When all the sec. indentations extend in one direction, the two films form a hollow body which is flexible in one direction and rigid in a direction perpendicular to it, as the indentations act as reinforcing ribs.

Title: Line spacing wheel coupling esp. for typewriter - has spring prongs acting as coupling elements positioned parallel to axis of platen
Inventor: LANGE HEINZ
IPC: B41J19/80
Filed: 1975-11-04
Abstract: The coupling for line-spacing wheel for e.g. typewriter, comprises spring prongs (26) on the coupling elements (11) which in the coupling position engage with the platen axle (1) via at least further coarse toothing (15, 19, 20, 21). In this way the torque exerted by the stepping mechanism to the line-spacing wheel (4) is transmitted directly over the control (24) to the platen axle (1). The coupling has the minimum possible parts and is assembled almost exclusively by plug mounting and avoids the use of other couplings such as screws or securing washers.

Title: Forging furnace with removable hood - having fixed hearth on which forging ingot is positioned
Inventor: PARDON PETER ING GRAD
IPC: C21D9/00
Filed: 1976-01-06
Abstract: Industrial furnace has a stationary hearth upon which are placed heavy forging ingots. The hearth is on the level of the foundry floor. The furnace structure is located above this in the form of a hood mounted on rails. Attached to it is a lever and drive mechanism for pushing it backwards and forwards. The hood can be of differing length, width and height. It can be of sectional construction, the various components being joined in angle, T or cruciform. One or both of the end walls can be removable or will move. The refractory cladding on the hood is of light construction. Used in foundries where large ingots are being forged. The construction described permits much heavy ingots to be heated. The hood, being of light construction, is relatively easily moved. Cleaning and maintaining the furnace is simplified. The hood sections can be exchanged. The need for using sand seals is avoided and better thermal efficiency is obtd.

Title: Pusher centrifuge drum has few performations - concentrated in rows outside oscillating stroke of pusher plate
Inventor: KARAU GERNOT
IPC: B04B3/02
Filed: 1976-01-21
Abstract: A drum for a centrifuge, esp. a pusher centrifuge with oscillating plate, comprises a drum wall which is completely closed (unperforated) except for one or more rows of holes. Pref. the rows of holes are ahead of the further limit of movement of the oscillating plate. More speficially the rows of holes are in a slightly divering region of the inner face of the drum wall, esp. in a cylindrical region of slightly increased dia. between two flat conical transitions. In addition each hole may have an outwardly diverging exit. Prods. having a very high solids content up to nearly 100%, can be centrifuged without excessive wear. In partic. solids of high specific gravity such as machine turnings which are to be degreased and mill scale and so on can be centrifuged. The lower limit to the particle size is reduced. The inlet and accelerating funnel can be more simply constructed, of shorter length and with a flatter apex angle than with previous designs. The pusher plate can be completely flat. The inlet opening to the accelerating funnel and also the inlet pipe can be of larger dia. thus permitting a higher throughput.

Title: Pulse regenerator for pulses of specified shape - has comparator controlling switches discharging capacitor
Inventor: HEHL HERBERT
IPC: H03K5/1252
Filed: 1976-12-22
Abstract: The regenerator generates pulses from signals on which strong interferences are superposed, and whose amplitude greatly varies. A differential amplifier serves as a comparator and as tripping voltage generator with a network at its input preventing overdriving it. A capacitor (C1) stores through a rectifier (D1) the positive peak voltage of the input pulses. When capacitor voltage exceeds a threshold value, the capacitor (C1) discharges through a switch (S1) and a resistor (R4) to the supply voltage negative terminal. Switching voltage is connected to the comparator one input through a voltage divider (R1-R3) and a switch (S3) from one of the terminals of resistor (R2). The switch is operated in the beat of the comparator output voltage, so that when the input pulse is positive, the switch (S3) is connected to the less positive terminal of resistor (R2), and after capacitor (C1) discharge opens the switch (S1). The switch (S3) returns to its other position as soon as the input pulse dies down.

Title: Excess current limiting in electric supply lines - uses at least one section of superconducting cable in current path
Inventor: GERLACH HORST DIPL ING
IPC: H01L39/16
Filed: 1977-03-24
Abstract: An arrangement is used for limiting excess current in electric power supply lines, such as may occur in short-circuiting. It comprises at least one section of a superconducting cable in the current path requiring excess current limitations. The matrix-metal and carrier metal and superconductor are designed in such a way with regard to cross-section and conductor material, that following any current exceeding the critical response or threshold current, increasing current division takes place between the superconductor and the matrix-carrier metal conductively connected to the superconductor. After the superconductor becomes normally electrically conductive, the threshold or limiting resistance remains above predetermined limiting value. More specif. a superconductory cable with Cu-Ni stabilisation is used.
