Title: Cams on rotary piston cylinder shaft - limit pivot angle, and work with control pistons to provide end position damping by oil throttling
Inventor: STEINBACH HERMANN
IPC: F15B11/048
Filed: 1978-02-27
Abstract: The rotary piston cylinder has an adjustable pivot angle limitation and end positiondamping, and comprises a shaft rotatable in a housing with at least one piston vane. The vane divides the cylinder into working chambers into which pressure oil is alternately fed. The shaft (1) on the driven side is extended, and is arranged in a second chamber closed by a cylinder cover (2). For pivot angle limitation, an adjusting cam (3) is attached to the shaft (1). This cam works in conjunction with stops on the cylinder cover (2). For end position damping, a control cam (5) attached to the shaft (1) works with control pistons which throttle the pressure oil fee when the end position is reached.
Patent DE-2812335-A1 (DE)
Inventor: FANTI HANSRUEDI
IPC: A47C23/06
Filed: 1978-03-21
Abstract: The bedstead has longitudinal supports (5) on which transverse slats (12) are attached movably by means of attachment devices (14). Each attachment device (14) has a holder (15) which is attached rigidly to one of the longitudinal supports (5) and is provided with a boss (15d) on the side facing away from the longitudinal support (5). A sleeve (16), in whose opening (16a) the end of a transverse slat (12) is seated, has two downwardly projecting limbs (16d) which grip at least partially around the boss (15d) so that the sleeve (16) can be tilted about the boss (15d). Clamped between the limbs (16d) above the boss (15d) is a hollow, rubber-elastic support (17) which rests on the boss (15d) and applies an upwardly directed force to the sleeve (16). The sleeve (16) can therefore also be displaced in an approximately vertical direction, causing elastic deformation to the support (17). <IMAGE>

Title: Oxide insulation layers for MOS transistors - esp. floating gate MOS memory transistors, or transistors using two electrodes made of polycrystalline silicon
Inventor: TOUCHY WOLFGANG DIPL PHYS DR
IPC: H01L21/321
Filed: 1978-03-31
Abstract: Oxide layers are formed between a first- and second- gate on the transistors, which use a silicon substrate. Substrate is coated with oxide, which is then covered with polycrystalline Si (poly Si) to form a gate electrode layer. The Poly Si is then partly oxidised to form an oxide insulation layer of prescribed thickness above the electrode, and then covered by a second layer of poly Si forming the second gate. The poly Si layer is pref. doped, esp. with P, so a prescribed oxidn. rate is achieved for this layer. Accurate process prevents short circuiting between the two gates.

Patent DE-2828185-A1 (DE)
Inventor: TAKE HIROSHI
IPC: G02F1/155
Filed: 1978-06-27
Abstract: An additional electrode is provided for developing a secondary electrochromic phenomenon on a counter electrode apart from the major electrochromic phenomenon which is developed between one or more display electrodes and the counter electrode. Current flows from an additional electrode to the counter electrode in developing the secondary electrochromic phenomenon. Coloration of the counter electrode, where the magnitude of an overvoltage of the counter electrode is small is stabilized to thereby enhance electronic properties of the electrochromic display. The material of the additional electrode is selected from metals having an appropriate ionization tendency with respect to an electrolyte, such as Mg, Al, Zn, Cr, Fe, Ni, Sn, and Pb, or a combination thereof. Otherwise, the material of the additional electrode is selected to be an inert material with respect to the electrolyte such as Ag, Au, Pt, Pd, In2O3, and SnO2 or a combination thereof. The combination which is composed of both the appropriate ionization tendency metals and the inert metals can be available for the additional electrode. The electrochromic display can be controlled under one of several groups of driving techniques consisting of a potentiostatic driving, a constant current driving, and a constant voltage driving method.

Title: Strong, clean-printing, typing ribbon - is of woven fabric impregnated with polymer soln. and inked on one side only
Inventor: KOHLE ULRICH
IPC: B41J31/02
Filed: 1978-07-29
Abstract: Typing ribbon has printing ink applied only on one side of it, and is made of textile material. The individual fibres of the textile are impregnated with the aid of a polymer and a plastics-bonded ink is applied to one side of the polymer-impregnated extile. The impregnant and the polymer of the applied ink have high affinity to each other. The typing ribbon combines the advantages of a normal textile ribbon with those of a plastics-tape ribbon ('carbon ribbons') viz. high mechanical strength of the former with clean, non-smudging typing of the latter.

Title: Transverse cutting machine for reinforced paper strip - has fixed and reciprocating knife blades mounted side by side
Inventor: MATTIEBE GUENTER
IPC: B26D1/45
Filed: 1979-09-05
Abstract: Paper bags are made from pieces of paper cut transversely from long strips. The paper is often reinforced with a woven fabric which is difficult to cut with the usual type of saw bladed rotary knife. This difficulty is overcome by using two blades (5,6) mounted side by side in a groove in the rotating blade holder (1). The first blade (5) is fixed to the holder (1) but the second blade (6) has a reciprocating lengthwise motion. This motion is imparted by a fixed cam over which the end of the blade (6) passes during each revolution of the holder (1). A spring keeps the blade (6) pressed against the cam.

Title: Modelling tool for denture wax patterns - with fingertip release collet and heating element
Inventor: HOMBRECHER FRITZ
IPC: A61C13/20
Filed: 1979-12-24
Abstract: A modelling tool for sculpture work on wax models for the mfr. of partial or complete artificial dentures consists of a plastic cylinder which carries at the forward end a tapered clamping device with a collet for the shaft of a modelling blade or spatula. A collar at the other end can be operated by a thumb to push the shaft forward and release the hot blade. A spring normally pulls the collet back into the clamping device to retain the tool. An alternative way to the extraneous heating of the blades is an internal heating coil so that the tool can be used for soldering. This greatly facilitates the frequently necessary change of modelling tools. The tool can be produced at low cost. It saves waiting for heating up after a change.
Patent DE-3003691-A1 (DE)
Title: Measurement and display of ball position in ball game - using photoelectric sensing across track width and measuring times of light beam interruption
Inventor: POKORNY ERICH
IPC: A63D5/04
Filed: 1980-02-01
Abstract: A ball game based upon balls rolling down a track provides a photo-electric sensing system to determine the position of the ball on the width of the track. Balls roll down a surface (30) and pass between a photo-electric sensing unit consisting of an emitter (32), reflector (33), and detector (34). The positions of the units are such that a fixed angle exists between the incident and reflected light. Any ball interrupts the light beam during its passage. The measured times of an interruption (t1,t2) allow a difference to be determined that is related to the position on the track.

Title: Temp. coefft. trimming of thin film resistors - by anodic oxidn. of intermediate layer and laser beam treatment
Inventor: BURGER KURT DIPL ING
IPC: H01C17/232
Filed: 1980-02-02
Abstract: Thin-film resistors for use in bridge circuits, e.g. for strain gauge measurements, are made of TaOxNy films which have to be trimmed to make the temp. coefft. of the individual resistors the same. This is done by formation of an oxide-enriched intermediate layer between the resistance layer and the oxide layer, pref. by applying an anodic oxidn. technique. In a second stage, any possible change in the absolute value of the resistance, caused by the first stage, is corrected by a laser beam treatment without affecting the temp. coefft. This results in temp.-compensated bridges of high precision.
