Patent DE-2816353-A1 (DE)
Title: Acoustic pulsed communications system - sends and receives sound waves via ground, using signals whose value depends on amplitude, frequency or phase, generated by vibrator
Inventor: EDELMANN HANS DR
IPC: H04B11/00
Filed: 1978-04-12
Abstract: The acoustic communications system sends messages via seismic pulses between a transmitter (12) and a receiver (14) coupled to the ground. The information is sent by varying the amplitude and/or frequency and/or phase of a defined signal. The signal is generated by a vibrator (12) whose amplitude, frequency and phase are variable and can be altered according to given functions. The signal is composed of a sequence of subsignals which in addition to being modulated with the information is also coded using e.g. a binary system. The subsignals consist of a sequence of frequencies and its inverse. The frequencies in the sequence have a constant amplitude.

Title: Automatic cabin pressure control for aircraft - with dual controls for added security and with rate of pressure change modulated
Inventor: ALDRICH HOWARD
IPC: B64D13/04
Filed: 1978-06-08
Abstract: The cabin pressure in the aircraft is monitored by two sets of pressure instruments, interlocked for a fail-safe operation. A primary control monitors the cabin and outside pressures and equalises the two while a secondary control monitors the rate of pressure change of the cabin and takes over the control when the rate exceeds a set value. The secondary control provides a modulated rate of change for the comfort of the passengers. The cabin pressure drop is limited to a set value below the sea level value for comfort and oxygen supply. Failure of either system ensures that the remaining one assumes full control.

Title: Pellet forming cutter for semiconductor wafer - has split grooved wafer adhesive bonded on foil for easy handling
Inventor: MIMATA TSUTOMU
IPC: H05K13/02
Filed: 1978-06-14
Abstract: The arrangement is for cutting a semiconductor wafer into semiconductor pellets. A foil is adhesive bonded on the rear face of a semiconductor wafer. Grooves are cut in the front face of the wafer for separating the wafer into pellets. The individual pellets are separated from each other by exerting push from the underside of the foil mechanically. The pellets are separated by fracturing. The first adhesive bonded foil can be connected to the second foil held in a frame. A pin is pushed against the rear of the particular pellet from the underside of the second foil.

Title: Vacuum freezing for recovering sweet from salt water - by alternately freezing and melting very thin falling films
Inventor: KUNST BERNHARD PROF DIPL ING
IPC: C02F1/22
Filed: 1978-10-26
Abstract: A pre-cooled salt soln. is divided into a fine, falling film by means of a contact layer consisting of fillings, vertical plates or hanging synthetic films, in a process for recovering a solvent from a soln., and esp. sweet water from salt water. The falling film is partially vaporised by a pump, the vapour is condensed on an ice layer on a second similar contact layer formed in a previous sequence until these ice layers are melted and sufficiently strong ice layers have formed on the first contact layer. The pre-cooled salt soln. is then fed to the second contact layer and the mode of action of the vapour pump is reversed until the first contact layer is melted and a sufficiently strong ice layer has formed on the second contact layer etc. Used to overcome the disadvantages of known freezing processes, esp. the prodn. of floating ice crystals or ice layers on cooled surfaces such as the necessity for large amts. of rinsing water and the resistance of thick ice layers to the transfer of heat whilst retaining their advantages.

Title: Glass optical waveguide fibre - which has oval cross=section used to separate two light waves polarised in orthogonal directions
Inventor: HUBER HANS-PETER DIPL PHYS
IPC: C03B23/049
Filed: 1979-07-28
Abstract: The fibre is pref. a monochromatic waveguide, and has a refractive index (RI) which is not rotationally symmetrical w.r.t. the radius of the fibre. The fibre is obtd. from a blank made by depositing at least one layer of glass on a tubular substrate, and/or varying the doping of the substrate or at least one of the glass layers. The blank is then collapsed in a non-symmetrical manner before being drawn into a fibre. The blank is pref. collapsed to an oval cross-section by non-symmetrical heating of the blank and then applying pressure while the blank is horizontal. Collapsing is pref. combined with drawing. The oval cross-section pref. has a ratio major axis: minor axis of min. 2:1. When two waves polarised at 90deg w.r.t. each other travel down the oval fibre, they possess different dispersion speeds and different wave numbers, so coupling between the two waves does not occur.
Patent DE-2931321-A1 (DE)
Title: Doppler laser radar system for missile guidance - detects and follows target by laser beam which serves simultaneously for missile guidance
Inventor: BORN GUNTHARD DIPL PHYS DR
IPC: F41G7/26
Filed: 1979-08-02
Abstract: The system is intended for independent moving target destruction by missiles, by a missile launcher actuated by a radio signal, or acoustic level detector responding to the moving target noise level. By use of a Doppler laser radar, the laser beam picks up automatically the moving target and this beam, following the target, is simultaneously used as a guide beam for the missile. The automatic launcher (10) of the missile (13) receives an advance trajectory information via the ratio or acoustic level link. The target indentification is obtained by the sighting Doppler spectra, or from the detected Doppler signature. The guide beam deviation provides the homing of the missile onto the moving target (12), while simultaneously the laser system (11) provides an active IFF (identification friend-or-foe) facility. Preferably a carbon dioxide waveguide laser is used with heterodyning reception in an optical sensor (11a).
Patent DE-2935166-A1 (DE)
Title: Automatic air pressure regulator - has membrane push rod and piston governor
Inventor: SINGBARTL GUENTHER ING GRAD
IPC: B60T15/50
Filed: 1979-08-31
Abstract: The system avoids the usual wide on/off margin of pressure regulators as presently used on pneumatic braking systems. A membrane (8) which forms the roof of a pressure chamber (10) expands upwards when the pressure of air from a compressor reaches a certain limit. A spring-loaded rod (12) follows the membrane and subsequently closes valve (18,19). A further increase of pressure separates the membrane from the rod seating and opens a by-pass through the hollow rod (12) into the outlet (4) via a chamber (13) which puts the system into the idling mode. Rising pressure in this chamber pushes a piston (14) against an adjustable spring (17). Decreasing pressure causes the membrane to retract thereby closing a valve (8,11) and opening another valve (18,19) thus putting the device into the pressure mode.
