Title: Three=dimensional microfiche viewer - uses screen with mosaic of beam splitting lenses to avoid need for viewing spectacles
Inventor: YEVICK GEORGE JOHANNUS
IPC: G02B27/22
Filed: 1977-03-11
Abstract: A viewer is for the 3-d observation of micro-fiches in black and white or colour, without the use of polarised viewing spectacles and for use with distributed micro-picture films. A screen (18) is used which is built up of a series of convex lens elements (19) in a regular pattern, with an opaque coating (20) on its inner surface. Under each lens element a pair of apertures (22, 24) is provided in the opaque layer, to serve as left and right apertures respectively. The spacing between the pairs of apertures and their relative positions in respect of the lenses are so arranged that light from the left aperture is refracted through a specific angle and that from the right aperture through another specific angle. Polarisers are incorporated so that the light from the left and right hand apertures is polarised in two orthogonal directions.

Title: Automatic flow regulator esp. for household fittings - has projections at outlets of perforations in deformable diaphragm to reduce flow noise
Inventor: SIEGMUND HELMUT-DIETER ING GRA
IPC: G05D7/01
Filed: 1977-04-02
Abstract: The automatic flow regulator for fluid and gas control consists of a rubber or plastics membrane (6) with several slotted or circular openings and is held at its edges in a metal or plastics housing (5). The membrane is deformed to a greater or lesser extent according to the pressure of the medium. The flow rate, limited by the number and size of the openings, remains constant within a certain pressure range. To reduce flow noise, a projection (10) on the end of the membrane on the outlet side of the channels deflects the fluid or gas stream towards the deflector (11) on the outlet of the regulator (11). The regulator can rapidly and easily be employed in household fittings to effect economies and to reduce flow noise.

Title: Nutritious medium for fodder yeast mfd. from manure, etc. - by hydrolysing conc. suspension and adding back decanted liq. fraction
Inventor: ZAITSEV KONSTANTIN PETROVITSCH
IPC: C12M1/00
Filed: 1977-08-31
Abstract: The process for converting liq. manure without stable litter into a nutritious medium for the growth of microorganisms esp. yeasts as a source of proteins and vitamins. The manure is sepd., e.g. by centrifuging into a clarified liq. fraction and a conc. suspension. The liq. fraction is sterilised and the conc. suspension is heated and then hydrolysed in the presence of a mineral acid as catalyst, e.g. H2SO4, the hydrolysed prod. then being neutralised. Prod. is treated, e.g. by ultraviolet irradiation to eliminate noxious, volatile, impurities, and is then cooled. Before neutralisation, the sterilized liq. fraction is admixed with the hydrolysed prod. The neutralised prod. is pref. desludged, e.g. via a decanting centrifuge. Used in mfr. of fodder yeast from pig manure, poultry droppings, waste from the futs of slaughtered animals in large abattoirs and similar organic refuse. Adding back the clarified liq. fraction greatly increases the yield of nutritious prod. while reducing mfg. costs. For example, a pig farm raising 108,000 pigs per year can produce 2,000 tonnes p.a. of fodder yeast to make up about 5,200 tonnes of fodder which represents a 10% saving on the fodder bill. The neutralisation process requires 20-80% less alkali when the liq. fraction is added back.

Patent DE-2900585-A1 (DE)
Inventor: STAUDENRAUSCH GEORG
IPC: A22C11/02
Filed: 1979-01-09
Abstract: A pickup 21 is connected with a portioning element that carries out individual portioning operations between two portioning pauses. By means of a sensor 22 and a counter 29 the actual values of the portioning operation steps are measured and are compared in a comparator 35 with a desired value from a desired-value setter 30. When the actual value reaches the desired value the programmed controller 27 for the next portioning operation and simultaneously the counter 29 is reset via the line 38. Thus the overrun of the portioning element after switching off is counted for the next portion. With each difference between desired value and actual value of a preceding portioning operation thus effectively the remaining desired value for the next portioning step is corrected.
