Title: Rotary ic engine with radial pistons - has spring loaded oscillating valves for cylinder openings
IPC: F02B75/18
Filed: 1974-09-02
Abstract: The engine rotor rotates on a shaft mounted in a stationary casing. The rotor has five cylinders with pistons having connecting rods attached to bearings on a disc running on a pin. The drive is transmitted from the disc by a chain or toothed gearing to the shaft. As the rotor rotates a fuel-air mixture is drawn in through ports into an annular space and into the cylinders through the oscillating valves which are actuated from the shaft. The charge is compressed and ignited by sparking plugs and then expands into an annular space, exerting a force against a projecting valve blade and causing the rotor to rotate.

Title: Synthetic gypsum treated with controlled amt of alkali - to neutralise insol. acid fluorine cpds, before mfg, plaster. (BE221076)
Inventor: MOUNIER FRANCOIS
IPC: C04B11/024
Filed: 1975-04-25
Abstract: Plaster is manufactures from synthetic gypsum by removing the accompanying acid substances with an alkali cpd. and dewatering the gypsum to form plaster. An aq. suspension of the sypsum is homogenised with an amt. (Q) of alkali which depends on the fluorine content (p) of the gypsum; the suspension is then drawn off, washed, filtered, dried, and roasted to form plaster. The alkali is pref. lime, CaCO3, NaOH, Na2CO3, KOH, K2CO3, MgO or MgCO3. The amt. Q is pref. equal to Qo + Kp, where Q is the number of OH equivalents/kg gypsum; Qo = no. of OH equivalents needed to neutralise the acids soluble in water per kg. gypsum; and K is a coefft. with value 0.2-0.6 Used e.g. in the treatment of gypsum obtd. as a by-product in mfg. phosphoric acid. The acid substances interfere with setting and/or result in plaster with inferior properties. The invention overcomes these problems without leaving excess alkali in the plaster, and the mechanical properties obtd. are similar to those of natural plaster.

Title: Hot air drying tunnel for fruit esp. prunes - with recuperative cooling tunnel discharging trucks through open exit
IPC: F26B15/16
Filed: 1976-05-14
Abstract: A drying plant for prod. which is carried on trucks through heat transfer tunnels. The plant is of the type which has a preheating tunnel followed by a main drying tunnel. Hot air is blown counter-current to the trucks in the pre-heater and co-current in the main tunnel. Part of the air discharged from the exit of the main tunnel is recycled to the gap between preheater and main tunnels to divide between them, provision being made for periodic withdrawal of trucks and the regulation of make-up air. All air now enters the system via a cooling tunnel added downstream of the main tunnel. The truck cooler serves as a recuperator returning heat to the two tunnels upstream. Air flow regulation is entirely by adjusting the effective lengths of the preheating and cooling tunnels. The cooling tunnel discharges trucks directly to atmos. with no door. Used for drying truck-loads of prod. in hot air tunnels, e.g. fruit and esp. prunes. Air flow does not have to be stopped and a door opened to discharge a truck. Thermal efficiency is raised by heat recovery in the cooling tunnel. Discharged trucks are cooled and easy to handle.

Title: Emotional influence reduction during diagnostic measurement - uses biological feedback system to detect rest condition
Inventor: AGOSTON MIHALY
IPC: A61B5/375
Filed: 1976-08-06
Abstract: The process reduces the emotional influence when making diagnostic measurements by instrument. By training in the biological feedback method the patient tends to assume the rest position, and detects the result of his activity in this direction with the aid of apparatus provided. The diagnostic measurement is only made when the detected instrument reading lies within a predetermined range characteristic of the rest position. During the biological feedback electro-encelographic investigations can be carried out, the feedback characteristic value being formed by the alpha waves. The start of the rest period is detected by the relative amplitude of the alpha waves above the predetermined wave level.
