Title: Animal food rich in protein and vitamins - by dry fermentation of starchy cereals pref maize
IPC: C12N1/14
Filed: 1975-02-13
Abstract: A food prod. rich in protein and vitamins is obtd. from a starchy material by the following dry fermentation process. Cereal grains are steeped in a nutritive soln. so that they absorb sufficient to maintain the growth of microorganisms, then the moistened grains are crushed to burst the pericarp and seminal tegument of the grains; the resultant mass is then seeded with a microorganism. Development then takes place at 20-30 degrees C whilst the mass is aerated in a fermenter. The mass obtd. is then dried. The microorganisms are chosen from Actinomycetes, Siphomycetes and Septomycetes provided that the strains are amyloltic, the strains are filamental fungi not producing multiplication or conservation spores, that their mycelium has about a 40% protein content on a dry basis, and finally that the compsn. of the protein amino acids is similar to soya or FAO protein. The prod. may be directly used for animal feeds and the proces avoids the high cost of a liq. fermentation process.

Title: Agitation appts. for bottles of champagne - causing progressive settlement of deposits on the corks of the upended bottles
IPC: C12G1/09
Filed: 1975-04-21
Abstract: Agitation appts. for bottles, partic. champagne bottles, is intended for use in the clarification of wines by causing the progressive settlement of deposits and sludge on the cork when the bottle is in the up-ended position. The appts. consists of a fixed element which supports a frame which can slide vertically and carries a series of cups for receiving the necks of the bottles; the movable frame has parallel rods which support the bottles at their greatest dia. When an impulse is applied to the frame the bottles rotated instantaneously and the sediment reassembles at a new lower level in the bottles. The movement can b eeffected mechanically and a complete revolution of the bottles can be effected by moving a hand lever. The sediment is progressively brought to lower levels and then to the cork by lowering the frame with respect to the fixed element. A considerable saving in time is effected because hundreds of bottles can be turned in a single movement instead of bottle by bottle as hitherto.

Title: Truncated pyramid shaped storage bin - has feet and carrying handles and can be superimposed or fitted inside another
IPC: B65D21/04
Filed: 1975-06-20
Abstract: Storage bins in the form of truncated pyramids, have two long and two short sides so that they can be fitted inside each other or built into a pile by rotation through 90 deg.

Bracing pieces (16, 17) connect and reinforce the U-section feet. The bracing pieces have a V-shaped cross-section, the outer arm of the V having a steeper inclination than the inner so that the handles on the bin below can fit between the feet.

Title: Bowl for uniformly pressing flat band material - has both driven core and outer cylinder, unloading bearings
IPC: F16C13/00
Filed: 1976-06-11
Abstract: A bowl for uniformly pressing flat materials such as films, paper, and textile piece goods, has a driven hollow outer cylinder rotating around a load bearing inner assembly, by which it is supported hydrostatically. An inner detail formed by a core carries on its flanges a concentric hollow cylinder in which, at least where the bowl presses against a holding up roller, there are radially extending plunger arrangements in axial rows resting on reinforcement bars. These bars are supported in turn by a flexible elastic pressure vessel. The outer cylinder has end flanges supported from the machine frame by glands and is driven by the rotating inner detail via a belt and rollers on the mutually opposing flange faces. The design gives a cheaper and less complicated pressure bowl for calenders, pads, etc. ensuring uniform loading across the nip, without leaks of the pressure fluid.
