Title: Pressure sensitive solid state sensor - has body of material with different state characteristics induced by pressure application
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01L21/00
Filed: 1974-03-02
Abstract: The solid state pressure sensitive sensor has a body exhibiting different state phases, induceable by pressure effects. In the various state phases the sensor exhibits a different specific resistance. The pressure variations are provided by an associated pressure exerting element, effecting the various state phases. Preferably the solid state body consists of a several components, such as telurium or selenium containing compounds, with typical representatives of the formulae CdxHg1-xTe or CdxHg1-xSe. The surface of the pressure exerting element may be less than 100 x 100 microns. When current is applied to the body its flow is changed by the pressure application. For this purposes the solid state body is fastened in a suitable support. The typical application is in semiconductor microphones.

Title: Oil field pipe joint - with two stepped threads and metal to metal face contacts received by undercut
Inventor: SCHATTON PAUL ING GRAD
IPC: E21B17/042
Filed: 1974-09-27
Abstract: A tool joint for oil field pipes has at each end of the sockets and spigots two threaded sections of different diameter. Metal-to-metal contacts are produced at the two forward ends of the two male threads with corresponding faces at the ends of the female threads.

Title: Remote control switch for electrical circuits in baths - has squeeze bulb to control diaphragm operating microswitch
Inventor: BAUMANN LUDWIG
IPC: H02J13/00
Filed: 1975-10-21
Abstract: Electrical apparatus in baths or other humid surroundings, for example air bubble or similar therapeutic baths, is controlled by a rubber bulb connected by a flexible pipe to a diaphragm which rests against the lever of a micro-switch. By squeezing the bulb the resultant air pressure deflects the diaphragm which trips the micro-switch to actuate the attached electrical controls.

Title: Mechanical overload safety device for wind-recording wheels - has wind wheel returned to position by counterweight
Inventor: SCHOENBALL WALTER
IPC: F03D7/02
Filed: 1975-12-27
Abstract: The wind-recording wheel is arranged in front of the support mast and is directed vertically against the wind. Strong wind (5) pressure rotates the wheel about a swivel axis upwards out of the wind direction. The wind wheel is held in the position against the wind by a counterweight suspended with two cables. The pivot shaft is arranged horizontally below and at an angle of 90 deg. to the wind wheel shaft. When the wind wheel is pressed up, the counterweight is drawn up with it by means of the cable arrangement. On declining windpressure, the wheel is drawn back into the position against the wind by the load of the suspended counterweight.
