Patent DE-2542573-A1 (DE)
Title: Metal and/or plastic container sheathed in insulating layer - with application of insulation after sealing of container
Inventor: MOSDELL RICHARD JOHN
IPC: B65D81/38
Filed: 1975-09-22
Abstract: The insulated sealed container filled with a solid or liquid substance in produced by sheathing the container walls, lid and bottom directly in an insulating layer, opt. after first applying an adhesive. The insulating layer may be applied by spraying on or foaming, or by coating the adhesive-coated container with insulating material flakes in a swirl chamber. The insulating layer may form a single- or multi-layer lable for the merchandise. The insulation is applied when the container has already been sealed, thus avoiding conversion of appts. for filling the containers. It is esp. suitable for e.g. cans of carbonated beverages, which maintain the liquid at low temp. for a long period after removal from a refrigerator or freezer.
Patent DE-2543514-A1 (DE)
Title: High temp. reactor - uses radiant heat supplied to porous reactor tube
Inventor: MATOVICH EDWIN
IPC: C01B31/30
Filed: 1975-09-30
Abstract: High temp. reactor e.g. for pyrolysis, decomposition and combustion reactions of organic and inorganic cpds. in which all the heat is supplied by radiation coupling comprises a reactor tube of porous refractory material capable of emitting radiant energy. Inert fluid is directed under press. through the porous tube wall to provide a protective blanket for the inside of the reactor tube. Reactants are directed in a predetermined path axially of the reactor tube and confined by the protective blanket within the central part of the tube. A heat shield directs radiant energy from an electric radiant energy source into the reactor tube to coincide with the path of the reactants. Since heat is supplied by radiation coupling the temp. of the reactant stream is independent of the temp. of the walls of the reactor tube. The tube therefore does not have to be made of material capable of withstanding the high temp. to which the reactant stream is subjected. The protective inert fluid blanket isolates the wall of the reactor tube from the reactant stream and prevents clogging by the accumulation of precipitates and deposits.

Title: Electrode type hot water boiler - has electrically insulating coating on inside of steel boiler vessel
Inventor: LENNARZ KLAUS
IPC: F22B1/30
Filed: 1975-10-15
Abstract: A vertical cylindrical boiler drum of mild steel (1) contains fixed electrodes (2) in the form of vertical sheets in the shape of arcs of circles which are arranged in concentric sets. Similar sets of electrodes (3) are connected to a central shaft so that they can rotate in and out of the spaces between the fixed electrodes. The water is heated by current flowing through it between the fixed and the movable electrodes. The rate of heating depends on the overlap of the electrodes and is controlled by adjustment of the movable ones. The inside of the boiler drum (1) is coated with a layer of electrically non conducting material which prevents stray phase to earth currents producing unwanted heating effects.

Title: Pressure control switch for dual circuit brakes - has two control elements with common spring to link tractor and trailer circuits
Inventor: OBERTHUER HEINRICH
IPC: B60T11/34
Filed: 1975-11-05
Abstract: The control valve has a retarded output so that a second brake circuit can be operated behind a first. This allows drum brakes to overcome the return spring pressure before the disc brake operates, on mixed brake systems. Likewise on trailer brakeS, the towing unit brakes operate after the trailer brakes are applied. On dual braking systems with diagonal control a simultaneous operation of the brakes is assured by having two brake valve elements in a common housing, operated by a common spring. The elements are coaxial for a compact layout. The single spring eliminates differences in characteristics, especially when the spring ages.

Title: Cleaning of swimming pool water - by recirculation with part filtration and addn. of oxidising agent whilst desalting
Inventor: KESSLER DIETER P
IPC: C02F1/52
Filed: 1975-11-21
Abstract: Swimming pool water both in and out-of-doors, in private or in public use, is cleaned by using flocculation or oxidation agents, and a filter with >=2 filtration stages. Only a part flow of the circulated water->=0.25 fold and =0.4 fold of the feed of the pump is cleaned. The addn. of the flocculant or the oxidising agent is effected in drops, possibly by hydraulic impulse, before the filter, upflow filtration being used, with swilling from above downwards. Exactly that amount of water corresp. to evapn. from the pool is let off continuously to keep the salts content constant. Method replaces the old circumstantial and labour intensive methods of cleaning the pool water, by a new elegant method without problems.
Patent DE-2554037-A1 (DE)
Title: High pressure hydraulic seal for sliding shaft - has pressure on seal controlled to suit operating pressure
Inventor: WEIGLE DIETER DIPL ING
IPC: F16J15/00
Filed: 1975-12-02
Abstract: The shaft (20) slides in the housing (21) and the high pressure (PH) is sealed by two U-section seals (22, 23). These seals are separated by an annular chamber which is divided into two regions (26, 27) by the piston (24). The region (27) is vented to low pressure by the hole (28). Any leakage from the high pressure (PH) past the seal (30) creates an intermediate pressure (PR) in the region (26). If the leakage increases, the pressure (PR) increases and pushes the piston (24) against the seal (30) increasing the sealing pressure and so reducing the leakage. The pressure on the seal (30) is thus kept to the minimum necessary for effective sealing which minimises friction between shaft (20) and seal (30).
Patent DE-2555775-A1 (DE)

Title: Wound magnetic strip elements - with corrugations on outside of straight strip straightened by bending on edge
Inventor: NOVIKOV GERMAN LEONIDOVITSCH
IPC: H02K1/16
Filed: 1977-02-08
Abstract: Stators and rotors of electrical machines can be wound from magnetic strip in a way which ensures a continuous flush contact of all turns on the inside but an interrupted contact on the outside. In the case of a stator, e. g the magnetic strip has slots (5) punched out along one side. On the other side, corrugations (2) of trapezoidal shape are pressed in from the edge (3) to the bottom of the slots (6). When the strip is wound to a coil, the corrugations straighten out but leave intermittent thinner strip sections on the outside of the wound coil. The inside heads (4) of the teeth, however, form a continuous flush contact with those of the next turn. Instead of trapezoidal, the corrugations can have a conical or pyramidal shape.
Patent DE-2715619-A1 (DE)
Inventor: SAKUMA TADASHI
IPC: G04B35/00
Filed: 1977-04-07
Abstract: In an analogue electronic timepiece comprising a minute hand mounted on a cannon pinion, an hour hand mounted on an hour wheel, a motor driven by pulses produced by an electronic circuit and a gear train connecting the motor pinion with the cannon pinion and hour wheel, means for setting the minute hand and hour hand to amend the time displayed by the timepiece comprises a setting wheel which is rotatable by a crown wheel in one direction for moving the hands clockwise and in the opposite direction for moving the hands counterclockwise. The setting wheel is coupled to the gear train by a friction pinion at a point in the train which is approximately midway between the motor pinion and the cannon pinion and hour wheel so that the blacklash generated in moving the hands clockwise in a setting operation is approximately equal to the backlash generated in moving the hands counterclockwise. The electronic circuit includes means for generating pulses at the conclusion of a setting operation so as to compensate for the blacklash in the gear train. Since the backlash is approximately the same regardless of the direction the hands are moved in the setting operation substantially complete compensation for the backlash can be attained regardless of the direction in which the hands are moved.
