Patent DE-2906042-A1 (DE)
Title: Roll film magazine for process camera - has motor drive feed and cutter with position altered to match feed into processor
Inventor: KRITZER WILLI ING GRAD
IPC: G03B27/58
Filed: 1979-02-14
Abstract: A roll rilm transport mechanism is for process cameras, using both sheet and roll film, and projection equipment. The transport unit is for automatic threading and film feed in the vertical direction. Several, usually two, roll film magazines are positioned on the same plane as the camera film input feed so that any one can be chosen for a particular exposure. To feed in the film the magazine output rollers couple to the film input feed roller drive components to feed the film up into the film plane, for exposure, to the required position for the format to be exposed. A bottom mask moves up to mask the bottom part of the film if less than full format is selected. The film feed comprises rollers and belts driven by a motor coupled to the main roller. With the film in position it is cut, and, after exposure, the belt drive units are hinged up on the main roller to feed the film out of the camera at the exit point into a cassette or processor.

Title: Blood lipid lowering agents - contg. methyl-L-methionine-sulphonium salts
Inventor: SERI KENJI
IPC: A61K31/195
Filed: 1979-04-17
Abstract: Blood lipid lowering agents contain as effective ingredient methyl-L-methioninesulphonium salts of formula (I): (where R- = (in)organic anion (e.g. Cl-, Br-, I-, SO4--, cyclamate, orotate, etc.)). Racemic methyl-methioninesulphonium salt is known to have blood cholesterol lowering action and is also effective against renal diseases of which the blood lipid lowering activity, however, is unsatisfactory. The inventor discovered that among the racemate the dextro-rotatory isomer is effective on renal diseases, and the levo-rotatory one has the blood lipid lowering effect.

Title: Gate electrode for FET - is narrow, and used as mask for ion implantation with reduced scatter effect
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L29/78
Filed: 1979-04-27
Abstract: The semiconductor body for a field effect transistor has n type conductive regions formed for source and drain electrodes. Between them is a gate electrode (8) forming a rectifying Schottley contact. This receives an ion charge so that charge carriers are injected through the region masked by the gate electrode. The gate electrode is of a reduced size so that scatter effect is reduced. Sufficient ions are implanted in the region below to allow a current to pass through. The gate electrode has a length (L) of less than one micron, pref. less than half a micron. The region is about 0.2 micron deep.

Title: Key hole fitting in door lock plate - has hole non vertically aligned, for secure key retention
Inventor: PASSOTER WERNER
IPC: E05B11/00
Filed: 1979-08-09
Abstract: The protective metalwork is for locks on doors. There is a special arrangement of the opening for insertion of a key to operate the lock component. This opening (9a) in the long plate or protective plate (9), and in the lock component (6)- or only in one of the two latter-is formed at an angle deviating conspicuously from the vertical. It can be in any position but pref. lying horizontally, at 90 deg. to the usual keyhole angle. After being passed through the first aperture (9a) the key must be turned before it will pass through the second aperture (7). Simple structural measures ensure that there is no danger of the key falling out of the plate when the door is banged, nor of it being easily pushed out from the other side.

Title: Concentrated solar mirror - made of laminated glass or plastic sheets or foils
Inventor: BEUTEL HELMUT DIPL ING
IPC: F24S23/70
Filed: 1979-11-14
Abstract: Solar rays concentrating mirrors are made of glass, sheets and/or foils of plastic material, by bending two thin planar elements over a shaped matrix and by bonding them together by an adhesive. When glass is used, the top element can be silvered at the back or two plain elements can carry a third thin reflecting glass or plastic layer. This reduces the cost of mfr. for thick curved solar mirrors and increases the mfg. precision, e.g. for cylindrical parabolic mirrors.

Title: Rotating opto-electronic appts. - has heat exchanger for conducting heat from component and from rotating section to fixed section using sealing ring
Inventor: FIBICH WOLFGANG DR ING
IPC: H05K7/20
Filed: 1980-05-02
Abstract: The heat conducting part (2) of the apparatus, is situated in a rotating housing (1), and has a heat conducting space (3) under its base, connected to the cooling body (8), by a tube (5). The cooling body (8), which is inside the fixed housing (10) serving as a heat exchanger, has a number of cooling fins, hollow in section, circular in shape and forming part of the interior space of the connecting tube (5). A sealing washer (7) around the connecting tube (5), separates and seals the fixed housing (10) containing the cooling body (8) from the rotating housing section (1). The heat conducting space (3), connecting tube (5) and the cooling body (8), form a cooling system, filled with a cooling medium (B), which condenses on the surface of the apparatus (2) and is fed to the cooling body (8), which in turn transfers the heat via a cooling medium (A) in the fixed housing section (10). The housing has an inlet and outlet connected to each other via a pump (12), which circulates the cooling medium. An essential advantage of this system is that only a simple shaft seal is required between the fixed and rotating housings (1,10).

Title: Regulating closure speed of injection mould - as function of remaining closure distance to eliminate difficult resetting procedures
Inventor: JUNG DIETER
IPC: B29C45/67
Filed: 1980-08-28
Abstract: An appts. for regulating the closure speed of the movable clamping plate of a mould of an injection moulding machine equipped with a double-acting, hydraulic mould closure/opening cylinder with throttles in the hydraulic supply lines, is constructed as follows. The closure velocity of the movable clamping plate (5) is compared, in a comparator (23), with a reference voltage associated with the distance between the plates (5,3); when the output signal from the comparator is other than zero, a correction signal which is dependent upon the distance between the plates is supplied via a closing switch (24) to the comparator of the control circuit. Pref. a correction value which is a function of the plate distance is formed in an appts. comprising an amplifier (26) possessing parallel feedback coupling branches (27,27',27"), which are activated according to the spacing between the plates and which have different amplification factors according to the plate distance. Each branch pref. possesses an electronic switch (28,28',28") which is governed according to the plate distance. More specifically, the entire closure and safety travel path of the mould is subdivided into sections, and an electronic switch is associated with the end of each section. If the mould is changed, the resetting does not require partic. experience or skill, but is virtually automatic.
