Patent DE-2848370-A1 (DE)
Title: Widened intake propeller cowl - has horizontal and vertical cuts and tapering inserts
Inventor: BECKER WILLI
IPC: B63H5/14
Filed: 1978-11-08
Abstract: The modified cowl is for a ducted propeller for a ship. The inlet side is widened by inserting wedge inserts (25) into cuts in the sides of the cowl, with the wedges tapering into the middle of the cowl. Triangular inserts (27) are fitted into the middle of the cowl, vertically in each side to compensate for the opening of the cowl. The inserts provide a simple widening control for the duct so that the expelled water stream provides improved steering control. The height of the duct is greater than the width at the intake end, and it is circular in the centre where the impeller is located.

Title: Spinning rotor lubrication - has capillary channels in guide body round rotor shaft
Inventor: GUTMANN GUENTHER DIPL ING
IPC: F16C33/66
Filed: 1979-08-28
Abstract: There are passages in the wall of the guide body, for the spinning rotor shaft, giving capillary channels for lubricant to pass from the supply to the lubricating point. The channel layout in the guide body gives a capillary gap ranging from one side to the other, with a spiral winding forming the capillary gap, so that the lubricant can flow through the winding wall and the passage. Designed for high-speed rotors, at about 80,000 rpm, the design gives good lubrication with minimum lubricant consumption, and which requires little maintenance.

Title: Drying appts. for wet grass - heats grass in steam atmosphere before squeezing some of moisture out
Inventor: DUSS FRANZ
IPC: F26B7/00
Filed: 1979-11-27
Abstract: The drier squeezes out part of the moisture content of fresh grass by passing it between compression rollers before delivering to the drying chamber. The fresh grass, which may be wet with dew or rain, is first heated in a steamy atmosphere and then squeezed. Immediately after the latter operation it can be loosened and exposed to a current of drying air. There can be a chamber (1) containing conveyors (3-5, 10-11) continuously delivering and discharging the grass and containing the pair of squeezing rollers (8). A water collection trough (2) divides the chamber in to top moist and bottom dry chambers (7, 9), a steamy atmosphere being created in the top one while drying air is circulated in the bottom one. The rollers are where the grass passes between the chambers.

Patent DE-3005015-A1 (DE)
Title: Structural sandwich material - with rigid foam centre intersected by webs joining coating layers on both sides
IPC: E04C2/296
Filed: 1980-02-11
Abstract: Sandwich material, for example for use in the construction of boat hulls, is made of a core layer of rigid foam, covered on both sides by a coating layer. At least one or several intersecting webs pass through the core from one coating to the other. The preferred core foam material is PVC, polyurethane, or polymethyl acrylate. The coating layers can be a glass fibre reinforced plastic, thermosetting or plastic material or a metal such as aluminium, copper or steel. The webs are made of the same materials as the coating layers. Such a laminate limits the deflection at load and eliminates both shear fractures of the foam and permanent dents in the coatings.

Abstract: The arrangement for trimming sailboard sails is for rigs with the sail luff fixed to a support flexibly connected to the board at its foot, and sail clew linked to the after end of a wishbone boom by a tensioning line . With one end secured to either boom or clew, this line is led around pulleys connected respectively to boom and clew, forming a tackle; through a jamming-cleat permitting withdrawal and a fairlead at the sail-support foot, to a belaying-cleat on that support. The free-end-portion of the line is elastic.
Patent DE-3008312-A1 (DE)
Title: Current regulator for stepper motor controller - has feedback transformer for rapid reduction of motor current at end of step
Inventor: WOERD GERARD VAN DER DIPL ING
IPC: H02P3/18
Filed: 1980-03-04
Abstract: The current regulator is used in a stepper motor driving the character disc of a teleprinter. In order to achieve accurate disc positioning it is desirable to reduce the current in the motor windings (M) as fast as possible. The desired result can be achieved with low power loss by adding a feedback transformer (RT). The transformer primary winding is connected through a freewheel diode (D3) to one side of the transistor switch (ST) controlling the output of a power source (S) to the motor windings. The secondary winding is connected, via a further freewheel diode (D2), directly to the power source. A typical transformer ratio is 1:2. When the switch (ST) turn off the stored energy in the motor windings and the external choke (L) is rapidly fed back to the power source (S). If at the same time all the winding routing transistors (T) are off, the stored energy in the choke (L) can be fed back through a further freewheel diode (D1).
Patent DE-3018214-A1 (DE)
Title: Telephone operator desk conversion for equipment status testing - has change-over key for giving keyboard addresses altered significance and is connected to multiplexer
Inventor: BURKART PETER
IPC: H04M3/60
Filed: 1980-05-13
Abstract: The system comprises a keyboard at an operator's office (BAP) which has its outputs connected to the inputs (1-Z) of a multiplexer (MUX 1) circuit and where the multiplexer has two further inputs used as channel markers. The normal channel is marked by an input (X) connected to logic '0' over a key (H) and a changeover switch (SK). An outgoing data line (DK 1) goes to a controller circuit (PS) at the exchange equipment where a demultiplex (DEMUX 2) holds an output (H) at an active switching level. When the changeover switch (SK) and key (H) connects to multiplexer (MUX 1) input Y, the distant demultiplexer produces an output (H') which sets the bistable (FF) and enables all the other demultiplexed keying outputs to be channelled to testing points of the exchange equipment. The response levels are passed through a multiplexer (MUX 2) where the serialized test responses pass via a return line (DK 2) to the operator's office. Synchronisation is obtained from a count position of a counter (TAG 2) and applied to the counter (TAG 1) of the primary sender at an input (SYN) over a separate synchronisation line.
Patent DE-3028705-A1 (DE)
Title: Minimal phase digital filter - adjusts sampling frequency for signal processing system using two series stages to multiply sampling rate
Inventor: GOECKLER HEINZ DIPL ING
IPC: H03H17/06
Filed: 1980-07-29
Abstract: The filter has two series filter stages the first of which is used to process the signal at the lowest sampling frequency, with the second stage used to raise the sampling frequency. The zero points of the function for the first filter stage all lie in the Z plane while those for the second stage lie on the characteristic curve. Pref. the first stage is both a minimal phase and a linear phase filter obtained by using the symmetry of the pulse response, the second filter stage being a minimal phase transversal filter with a non-symmetrical pulse response. The filter is simplified.
