Title: Protein recovery from protein extracts - by precipitating as complex, decomposing the complex, recovering the protein and regenerating the pptg agent
Inventor: SCHWENKE KLAUS DIETER DR
IPC: A23J1/20
Filed: 1973-05-04
Abstract: Process is carried out by (1) converting the protein (esp. albumins) into insoluble complexes in the known way using complex-forming agents such as dextran sulphate, starch sulphate, polyphosphates or tannin, (2) bringing the complexes into soln. and decomposing them into their components by adjusting the pH, preferably to >5, or by using salts, (3) separating the protein by heat coagulating (e.g. at 501-00 degree C) or by salting out and (4) recovering the protein precipitating agent remaining in solution and reusing it. The process allows extraction of proteins (both native and denatured) in protein extracts, especially of vegetable origin, giving products which do not contain precipitating agent residues and are suitable for foodstuffs applications.

Title: Building site clearance - concrete structures cleared by piling, excavating one side, and tunneling out
Inventor: STAUFENBIEL ALWIN
IPC: E02D15/08
Filed: 1973-08-24
Abstract: Building ground is cleared of air raid shelters or concrete building structures. The ground is secured by sheet steel piling, and on one side an excavation with a fall toward the building works is dug out. A tunnel is then made from it to the other side, and the middle part beneath the building is excavated from the opposite long sides of the tunnel and downward, with digger dredgers or earthmovers. The building is caused to sink progressively under its own weight. Preferably the digging from the tunnel is with the same or opposite direction of motion. The movement is effected by steel cables from the opposite sides into the middle of the tunnel, back and forth. The earthmovers are connected by cables to lifters which also fill lorries with the spoil. Less work is required than for explosive shattering of heavy, e.g. military, concrete and its subsequent piecemeal removal.

Title: Manicuring device with provision for collecting debris - has cover plate and collecting dish together with support for other fingers
Inventor: HERTER KARL
IPC: A45D29/05
Filed: 1973-09-15
Abstract: The manicuring gadget has a baseplate and a cover plate made from impact resistant plastics. The collecting dish is bounded by the raised edge of the baseplate. The edge is connected to the support holes used for fingers which are not being treated. The finger support stand is arranged in a radial direction from the edge of the baseplate. The support has a groove for accommodating a finger. This device is a circular tray with two holes for two fingers while the middle finger rests on the support. The advantage of this support is that it forms a firm support during the filing of the finger nail and it collects the debris. Other finger care operations can also be carried out.
Patent DE-2346812-A1 (DE)
Title: Throttle valve for air extractor vent funnel - uses a pliable plastic foil tube attached to the inner valve cylinder
Inventor: BONSEN HORST
IPC: F24F13/08
Filed: 1973-09-18
Abstract: The vent housing has a funnel shaped opening and is fitted with a similarly shaped inner valve element with a cylindrical inner end. A thin and pliable plastic tube is fitted around the cylindrical portion and extends beyond all moving parts of the regulating mechanism of the valve. The normal air flow through the valve, i.e. inward suction, keeps the foil tube open and extended. On occasions of unwanted reverse flow due to pressure build up of air, the foil tube collapses around the cylindrical valve tube to prevent unwanted discharge of stale air from the vent into the room.
Patent DE-2347073-A1 (DE)
Title: Middle edge-on strip plywood layer mfr. - using throughflow gluer for glued, turned and assembled strips
Inventor: STEINER KLAUS DIPL ING
IPC: B27D1/06
Filed: 1973-09-19
Abstract: Middle-layer panel is made for plywood panels of given length and width. Layers of wood veneers or boards are superposed with the fibres running the same way but with the joins offset, and are glued together to form a multilayer wood strip. This is then cut into bars by multi-blade saws; the bars are turned through 90 deg. about their long axes, abutted, and glued together, so that their cut faces form abutment faces for the cover veneers of the plywood. Before turning and assembly of the bars, a cut at 90 deg. to the length establishes the middle layer length. After gluing, turning and assembly, the bars are guided at 90 deg. to their length through a throughflow gluer and there joined together by heat and press. to the middle layer length, from which a saw guided longitudinally of the bars parts one of the middle layer panels after the others at the preset width.
Patent DE-2353453-A1 (DE)
Title: Bobbin for magnetic tapes has removable side cheeks - bobbin core has slanting steps to receive side plates with holes which fit onto steps
Inventor: KRATZER DAGOBERT
IPC: G11B23/037
Filed: 1973-10-25
Abstract: The bobbin has the coaxial circular side faces of the core shaped to form slanting steps whose diameter is such that it fits into the holes of flanged plates. The flanges have slits cut in them running radially outward from the holes and which terminate as circular holes. The inner faces of holes in the flanges are also slanting and the angle of the slanting is the same as that of the steps on the core. The holes at the ends of the slits give stress relief and so prevent failure of the flanges by tearing. The slits allow spring action of the flanges so that their slanting inner edges can snap-fit onto the core.

Title: Beverage can cooler - has increased efficiency by evaporating liq. in heat transfer element not in cartridge
Inventor: WILLIS SAMUEL C
IPC: F25D31/00
Filed: 1973-11-19
Abstract: Beverage cooler has a cooling element with an outlet above the level of the beverage, and an opening into a coolant container from which coolant passes through the element and out of the opening, reaching lower liq. temps. with use of less coolant. The coolant container holds liq. coolant with a release valve that, when open, permits coolant to flow to the element in liquid form, so that the liquid evaporates in the element instead of in the container. A flow controller for the flow in the element sets a speed so that evaporation is progressive along the element, to maintain a min. temperature between the temperature of the beverage and the outlet temperature throughout the cooling cycle, as determined by a cooling time period of less than 2 1/2 min.
