Patent DE-2361473-A1 (DE)
Title: Variable size ships rudder - with extending blade operated by hydraulic ram to improve low speed control
IPC: B63H25/38
Filed: 1973-12-10
Abstract: the rudder blade has a second blade mounted inside it on a runner along the top and bottom of the main blade to extend out of the end of the rudder and increase its effective length, rather like aircraft flaps. The extension process is controlled hydraulically, or even pneumatically, by rams inside the rudder blade and coupled to the main controls by a supply line through the middle of the rudder support post. An alternative design has the space behind the extension blade directly coupled to the hydraulic/pneumatic supply with sealing lips between the main rudder and the extension.

Title: Metal installation flange for double glazed panels - is suitable for use with replacement panels in existing frames
Inventor: PEETZ HANS-DIETER DIPL ING
IPC: E06B3/54
Filed: 1974-02-01
Abstract: The method of mounting is for a double glazed window panel, especially suitable for use when replacing existing single glaxing where traditional methods may not be sufficiently strong for the increased weight. One of the sheets of glass (1) is made larger than the other (3) to form a peripheral projection and the two sheets are sealed (4) together around the edges. The fixing method consits of bonding (5) a piece or pieces of sheet metal (8) around the projecting edge of the larger plane and to the seal so as to form a projecting flange or a number of projecting portions which can be drilled (9) to take screws for affixing to the frame (2). Various shapes of flange for internal and external fixing are possible and malleable metal may be used so that the flange may be bent out to fit the frame on site.

Title: Lotto form completion machine - has prepared printing plate from which mirror image of crosses etc. can be transferred
Inventor: TREUTNER WOLFGANG
IPC: B41F17/00
Filed: 1974-02-09
Abstract: The printing plate can, depending on the design of machine, be flat or curved so that it can be placed round a printing roller should it be required to fill in or print a large number of lotto forms. In a flat-bed design, for example, the movement necessary to bring the stamp onto the base is achieved using a hand lever, although in alternative designs other power sources can be employed e.g. hydraulic, worm gear drive or electrodynamic. In operation a blank lotto form can be placed on the bed followed by a carbon paper sheet or other inking device. The printing plate or stamp is them pressed down onto the top of the sheet to transfer its image to the form.

Patent DE-2606159-A1 (DE)
Inventor: WEISS HARDY PETER
IPC: B32B7/027
Filed: 1976-02-17
Abstract: In the multi-layer insulation material, highly reflecting layers and layers of open-pored foam are arranged alternately. Due to the use of this combination of materials, the insulation value is considerably increased owing to the open porosity of the foam and the associated reduction in the radiant heat exchange between the highly reflecting layers. The multi-layer insulation material can form the core of an insulation element. In this case, the sealed core can be filled with an insulating gas. The shell consists of another insulation material.

Title: Piezoelectric electroacoustic transducer for telephone instruments - has oscillating diaphragm surface partially covered with piezoelectric material and nodal line thickness depending on resonance point
Inventor: BOEHME WOLFGANG DIPL PHYS
IPC: H04R17/10
Filed: 1976-03-31
Abstract: The pickup has a diaphragm provided with a layer of piezoelectric material on at least a part of its oscillating surface. Mechanical oscillation conditions determined by its shape and kind of its fastening produce at least one resonant point in the frequency range of interest. The layer of piezoelectric material has nodal lines of different thickness or polarisation, depending on position of the resonance point, or at least one of the resonant points.

Title: Digital measurement of car wheel speed - producing variable prop-portional to reciprocal of speed and comparing with valves determined by approximation straight lines
Inventor: LIERMANN PETER
IPC: G06F1/02
Filed: 1976-04-30
Abstract: The wheel or rotating component is scanned by a pick-up which generates a series of signals proportional to the speed of rotation. An electric measurement variable is generated by the measuring device corresponding to the reciprocal of the speed of rotation. This variable is compared with values corresponding to speed intervals in a specified speed measurement range, previously determined by approximation straight lines. They are weighted by a first specified factor determined by the selected approximation line in the respective interval. The twin complement is produced from the weighted variable, and weighted by a second factor, so that the product of the two weighting factors is equal to the slope of the approximation line.
