Title: Relieving valve for rotating piston blower - builds up pressure while electric motor is running up to speed
IPC: F04C28/28
Filed: 1977-11-10
Abstract: The relieving valve is used in a rotating piston blower. The electric motor driven blower is relieved on starting. This valve is closed after electric motor is connected from star to delta. This blowing valve has few moving parts and operating condition is reached rapidly. On the relieving flow path between the valve seat (20) and the valve closure element (24) which is kept open by a spring (24) is a restrictor for throttling the relieving flow. This generates pressure increase in the valve supply pipe (15). The valve body is connected to a diaphragm which closes the valve against the action of the spring. The time for filling the pressure chamber after starting of the blower (1) and hence response of the diaphragm lasts longer than the starting, star connected period, of the electric motor.

Patent DE-2817497-A1 (DE)
Inventor: GOEDE SIMON
IPC: G01K1/02
Filed: 1978-04-21
Abstract: The aim is for battery-powered clinical thermometers to have a service life of more than one year without a change of battery even when they are used several times daily. For this purpose, after a warming-up time of approx. 30 sec a measuring device carries out individual measurements of short duration in intervals. The respective measured value is stored in an intermediate value memory (3) and is not represented in an LCD (4) until at least two successive individual measurements have identical or virtually identical results. In a preferred exemplary embodiment, a bistable multivibrator (5) is provided whose output (Q) is used to control the supply voltage (U+, U-) and to control an intermediate value memory (3). One control input (S) of the bistable multivibrator (5) is fed a start command (IS), while after the measurement phase the second input (r) is fed a stop command (Ir) from an analog-to-digital converter (2). <IMAGE>

Title: Sewage disposal system - using solar heat for conversion to agricultural crust, electricity generation and fresh water
Inventor: SCHWALBE GEB BEYER BAERBEL
IPC: C02F1/04
Filed: 1978-08-08
Abstract: A system for the disposal of refuse and sewage from towns near desert areas uses mobile rectangular containers on wheels which are open at the bottom and can be sealed by sealing pads against the ground when the tank has been lowered by turning the cranked axles. Solar heat is directed to inclined top plates and transferred to the tank contents by lenses and concave mirrors. This leaves a crust, after all moisture has been evaporated, which forms a cover for instant plant growth on the desert sand. The steam is passed to a turbine for electricity generation and the condensed steam is used as fresh water.

Title: Premoulding automobile internal fibrous mat components - in compressed air tank on single mould with cloth over mat
Inventor: PELZ ERNST
IPC: B27N5/02
Filed: 1979-11-14
Abstract: A method of premoulding passenger automobile components comprising a fibrous mat consists of first softening the fibrous mat to render it flexible, than applying it over a pattern having the required shape in a pressure tank, covering the mat with a cloth and applying compressed air to the free side of the cloth to press it to shape. This process is extremely simple and inexpensive and requires the use of only one mould, not a two-part mould. The pressure required is comparatively low and compressed air is adequate for this purpose. Typical pressures are 2-5 bar. The type of tank required is that used in the construction of wooden aircraft.
