Patent DE-2644112-A1 (DE)
Title: Electronic switch for explosive atmosphere - has external coils with release element altering coupling between resonant circuits of oscillator and receiver
Inventor: SABROWSKY LOTHAR
IPC: H03K17/97
Filed: 1976-09-30
Abstract: The electronic switch consists of an oscillator whose resonant circuit (32, 33) is inductively coupled via an external circuit (53, 54) to the resonant circuit (42, 43) of a receiver. The external circuit is located in an explosion proof area (O) whilst the oscillator and receiver and their associated resonant circuits are located in a non-safe area (1). The external circuit consists of two coils whose coupling is altered by the release element (60) of the switch. This change causes a corresponding change in the receiver's resonant circuit which triggers a digital amplifier (e.g. transistor switch) that operates a relay.

Title: Tablets for detecting gastric acid - contg. indicator in dragee-coated core
Inventor: BOSKAMP ARTHUR
IPC: A61K49/04
Filed: 1976-11-13
Abstract: Tablets for detecting the presence of gastric acid in the stomach comprises a core contg. methylene blue (or other dye or indicator) in a dragee coating. The tablets dissolves in the stomach (colouring the urine) when acid is present but passes through the body undissolved in the absence of acid. Barium x-ray contrast agents or isotopes can also be used instead of the dye, in which case the dissolution of the is monitored radiologically. The tablets are easier to prepare and more reliable than "Desmoid" pills, in which the core is wrapped in a rubber film and tied with soluble catgut.

Title: Single strip cardboard package for bottles - has four panels forming top, base and sides, with attached flaps forming ends of package
Inventor: HUBERT PETER
IPC: B65D71/36
Filed: 1976-12-08
Abstract: The portable bottle packing is made from a single strip of material, preferably cardboard, the cover, first sidewall, bottom, second sidewall and gluing lugs being in line. Flaps are attached to their sides to form the end walls. It is for use with bottles tapering towards the top. Seen in the lengthwise direction of the strip of material, the cover (1) is shorter than the bottom, so that the sidewalls(2) bear against the tapering bottles. The four end flaps (6) attached to the sidewalls each have a bending line, starting halfway up their lines of attachment, and extending obliquely upwards to the middle of their top edges. The upper part of each flap is folded inwards along this line until it bears against the bottle neck. The two flaps (8) attached to the cover act as reinforcing components for the packing, there being a bending line running along each at the middle, allowing it to be pressed inwards against the bottle neck.

Patent DE-2700461-A1 (DE)
Inventor: KOCH FRIEDRICH-KARL
IPC: B23D33/00
Filed: 1977-01-07
Abstract: The forming press (1) contains a shearing station (4) for cutting off a piece from the round stock (2) drawn into the station section by section up to an adjustable length stop (5), one or more forming stations (8) and a measuring device (12) for monitoring the pressed parts at least as regards constancy of volume, dimensions and/or shape. The length stop (5) has a motor-driven adjusting drive (6) which is connected to the measuring device (12), forming a feedback control. The pressed parts are fed to the measuring device automatically by means of a feed device (9). The automatic control system adjusts the length stop (5) during the operation of the forming press so that the decisive dimensions of the pieces of material always remain constant. The measuring device can also be arranged ahead of the forming stations, the pieces of stock thus being monitored before being processed. <IMAGE>

Title: Thin film structure sputter mask - with thin structuring mask and receding thick supporting mask
Inventor: PICHLER ALFRED
IPC: G03F1/20
Filed: 1977-08-30
Abstract: A mask to produce electronic modules by a plane sputtering process, consists of a first thin structuring mask which defines the contours of the desired structure.

Title: Qualitative and quantitative evaluation of reactions - by measuring the amt. of light produced during reaction
Inventor: NOELLER HANS T
IPC: G01N33/535
Filed: 1978-05-11
Abstract: the method can be used in the qualitative determn. of hepatitis-B-antigens. The process is extremely sensitive and does not have any of the actinic dangers associated with the conventional radioisotope techniques. The chemicals needed for the reactions can be kept at the suitable storage temps. for many months without being limited by half-life considerations. The sensitivity of the method is considerably greater than that of similar enzyme labelling by evaluating the colour change (rather than the light yield). The test is simple, does not require many people to operate and can be performed with the scintillation counters previously used in RIA-techniques. The process can also be used for oxidation processes, enzymatically controlled reactions, and immuno reactions, but esp. in the determination of Hepatitis-B-antigen.
