Patent DE-2335514-A1 (DE)
Title: Hot air treatment in fluidised bed - esp. of heat sensitive material with air inlets above bed floor
Inventor: KASPAR JAN DIPL ING
IPC: B01J8/18
Filed: 1973-07-12
Abstract: A fluidised bed operates with hot gas, esp. hot air; all the hot air inlets are in the fluidised be chamber at some distance above the chamber floor and oriented so as to directed the hot air jets towards the floor; in all parts of the chamber, the inner walls which come into contact with the flow paths of the incoming gas are insulated. Pref. the directions of the jets as viewed in plan are oriented not towards the centre of the chamber but at an acute angle from it. Both this angle and the angle of vertical tilt are pref. adjustable. In any form of treatment where hot air or gas is used, but in particular where a heat sensitive granulate is treated in the bed. The positioning of the hot air inlets within the chamber rather than below a perforated floor ensures that neither the floor nor any other part of the structure is at a temp. excessively higher than the material in the bed. It is not therefore necessary to allow for such a high temp. drop between incoming air and treatment temp., nor is there a danger of heat-sensitive material becoming damaged by contact with hot metal parts.

Title: Automatic fresh fish gutting - on fast revolving turntable with fish held by tails
Inventor: LAPEYRE JAMES MARTIAL
IPC: A22C25/14
Filed: 1974-04-09
Abstract: In an automatic fish gutting machine, the fishes are held on a turntable by their tails. When the centrifugal force is high enough to sever the entrails but not the flesh from the bony structure, the entrails are projected through the fish's mouth or, if the head is cut off, through the open end and are washed away inside a tank by the water sprays. This labour-saving method can be applied both on board ship soon after the fish have been caught, or in port.

Title: Draw die for metal wire - has hardened body with vapourized diamond deposited on hole surfaces
Inventor: WIEMANN HANS-JOACHIM
IPC: B21C3/02
Filed: 1974-09-26
Abstract: A die for drawing thin metal wires is made from hardened steel or sintered carbide (1). Since the die hole is subjected to extreme frictional wear, the harder the surfaces (2, 3, 4) of the die hole, the longer is its useful life. This is achieved by placing the die with the preformed hole in a vacuum chamber so that vapourized diamond can be deposited on the hole surfaces by means of a cathodic gas discharge. A layer of 0.5 to 5 mu m is formed in this way. The hole in the metal body is so dimensioned that no further treatment is required after the formation of the diamond layer.

Title: Circuitry for control facility with PI structure - has series connection of PD element with voltage-controlled oscillator
Inventor: FOUQUET HANS-HERMANN DIPL ING
IPC: G05D11/16
Filed: 1975-04-10
Abstract: The voltage-controlled oscillator is operable during the period of disconnection of the two switching stages exclusively by the control deviation signal. During the period of connection of one of the two switching stages the oscillator is also operable by a resetting signal with a polarity opposite to that of the control deviation signal. The magnitude of the resetting signal is adjustable according to the ratio of the required transit time to the actual transit time of the servo drive. When the control deviation signal vanishes, the period of connection can return to a fixed fraction of the total transit time of the servo drive.
