Title: Equipment for continuous measurement of magnetic tape remanence - using a permanent magnet writing head with a soft iron disc
IPC: G01R33/14
Filed: 1970-10-16
Abstract: The magnetic tape is held in a fixed configuration as it passes two heads, one for applying a specified magnetic field and the other for detecting the remanence. The tape may be guided in a straight path by suitable elements, or alternatively may be stretched round the circumference of a relatively large wheel. The writing head consists of a cylindrical permanent magnet with a soft iron disc at each end. Each of these has a rubber type which is in contact with the magnetic tape, so that an airgap of fairly constant magnitude is established between the head and tape as it passed underneath. The reading head, mounted further along the tape, is of a roughly similar but more complex form, and supplies an output signal down a cable (26) to give a reading of the remanence.

Inventor: BISCHOFF EDELBERT DIPL-CHEM DR
IPC: C08F8/00
Filed: 1971-10-21
Abstract: The tensides are acids which as their salts with Zn or Zr are intermolecularly cross-linkable with themselves or with non-tensides contg. acid gps. Prefd. are amine and/or ammonium salts of 10-18C carboxylic acid opt. ethoxylated to 10 ethylene oxide units/molecule, sulphosuccinates of 6-12C fatty alcohols or alkylaryl-, fatty alcohol- or fatty alcohol ether-sulphates or sulphonates.

The dip tube assembly (8, 11) maintains the aerosol valve in its open position by means of a thin stem (9). The pressurised container type cannister also has a countersunk mounted valve seating (2) for the aerosol dosage valve. The closed pressure container is filled and not the open one as is usually the case.
Patent DE-2319980-A1 (DE)
Title: Combined type formation tunnelling machine - has bit made up of grinding head, chisel bit and knife for differing hardnesses
Inventor: BOLOTIN EWGENIJ M
IPC: E21D9/11
Filed: 1973-04-19
Abstract: A grinding head, a chisel bit and a knife make up the cutting element, and are set so their cutting planes approach the formation in that order. These elements are set on the head of the tunnelling machine with all grinding heads coplanar, and all chisel heads co-planar. The arrangement of bits on the head protects the soft formation tools from damage by excessive work on hard formations. When the formation is soft enough to allow the grinder to sink in without cutting, then the chisel bit attacks the formation and if this sinks in then the soft formation is easily cut by the knife.
Patent DE-2331862-A1 (DE)
Title: Pressure release valve for carton - flexible membrane under perforated disc
Inventor: WEIGOLD HELMUT
IPC: B65D77/22
Filed: 1973-06-22
Abstract: An aperture in the wall of the container is covered with a circular convex plate, also with an aperture in line with that in the wall of the container. Stretched over the convex plate is a membrane made from an elastic material which itself has an opening to one side, not in line with the others. With pressure rising within the container, the gases escape through the apertures into the convex valve, pushing up the elastic membrane allowing the gases to escape through its aperture. When pressure has been released the membrane contracts to cover the valve aperture, sealing the container once again.

Title: Evaluation of peak of voltage/time function - for study of wave forms by means of amplitude step
Inventor: HEUFELDER GUENTER DIPL-ING
IPC: G01R29/00
Filed: 1973-07-24
Abstract: The arrangement is for evaluating a volts/time function depending on different time classes of fixed time intervals, of consecutive waveforms using amplitude stepping. A shift register transmits a signal containing the peak value to the preselected flip-flop and than via the 'NOR' gate, exclusive 'OR' gate, the inversion stages to 'NOR' gates. The time register issues the corresponding time signal and measures the required time. 'NOR' gates feed the signal to indicators which give the coincidence of signal. Amplitude step signal against which the time measurement is dependant is adjustable.

Title: Laser diode used in electro-optical distance measuring instrument - has phase mixing without precise adjustment of optical elements
Inventor: NUENLIST RENE
IPC: G01S7/481
Filed: 1973-10-12
Abstract: The laser diode is operated below its laser threshold to produce uniform phase mixing of the light rays emitted by the laser diode surface. Phase mixing thus takes place already inside the emitting diode, as the active layer has a greater refractive index than the adjacent areas and acts as an optical waveguide. The laser diode is pref. a superluminescence diode, and the light-emitting face of the diode may be at an angle to the active layer. The rays emitted by the diode first undergo multiple reflection at the interfaces between the active layer and the remaining diode material.

Abstract: A cigarette making machine feeding a packaging machine, has a conveyor preceding the packaging machine which delivers loose cigarettes to an intermediate store which acts as a buffer between them in which part of the storage space is formed by a moving conveyor belt so that the stored quantity can be varied. Control devices on one or both machines can be actuated by control circuits, which receive signals from signal transmitters and upper and lower limiting devices adjacent the buffer store so that the drives can be changed to modify and control the quantity of cigarettes passing between the machines. The control devices operate at a low limit and a high limit of the quantity contained in the buffer store.

Title: Asymmetrical door hinge - has pins and bushings of unequal length to facilitate hanging
Inventor: POENSGEN ROBERT
IPC: E05D3/02
Filed: 1974-06-25
Abstract: The design enables the longer pin to be inserted into the corresponding bushing first and by using this as a guide, the second pin can be entered easily. The location of the two hinge sets is interchangeable. An alternative arrangement envisages both pins in equal length and bushings of different length. The difference in length on the latter set is made up by a washer. The design avoids the difficulty experienced when hanging doors which are fitted with conventional hinges and where both pins have to be centered against the corresponding bushings at the same time.
