Patent DE-2415705-A1 (DE)
Title: Electro-deposition of metals to obtain very uniform deposit - esp. on printing rolls, using membrane round the roll
Inventor: ESSER HERBERT
IPC: C25D7/00
Filed: 1974-04-01
Abstract: A device for the electrodeposition of metals on objects with a circular cross-section, esp. rolls, where the object forms the cathode in a bath using continuous filtration and make-up of the electrolyte in a circulating system in which a pump returns the liq. to the bath, and where the object is rotated on its longitudinal axis. A wall, or membrane, permeable to liq., extends along the length of the object and is closed at the ends. The electrolyte is pref. fed through tubes which extend along the length of the object so the liq. flows tangentially towards the object against its rotational direction; the membrane pref. has a U-shape, the legs extending upwards round the object which is partially immersed in the bath. Used e.g. for Cu plating in the Ballard process, i.e. plating rolls for a rotary printing machine used in printing journals. Eliminates the formation of a structure in the deposit which is reproduced in the printing process; this structure must normally be removed by grinding which is time-consuming and costly.

Title: Oxygen supply unit for use in oxygen-deficient waters - e.g. lakes, rivers, etc.
IPC: C02F3/02
Filed: 1974-04-05
Abstract: Rectification of oxygen deficiency in lakes, rivers, etc., by supplying oxygen from oxygen-liberating chemicals to the water at the bottom of the lake etc., more esp. using a pressure vessel emchored to the bottom and contg. oxygen-liberating chemicals, partic. chlorates, in cartridges or candles provided with ignitors, the oxygen produced being delivered in the region of the lake bottom through perforated tubes connected to the vessel. Since there is very little circulation of the water itself there is no carry up of fertiliser material from the bottom or catastrophic plantation growth due to replacement of warm water at the surface by cold water from the depths. The use of substantially pure oxygen reduces the volume of gases to be handled and no compressor is required.

Title: Electric coffee maker with filter - is programmed to allow infusion of water and coffee for set time
Inventor: DIX WALTER
IPC: A47J31/06
Filed: 1974-06-11
Abstract: The filter coffee maker with a safety-controlled electric heating system comprises an aroma-and air-tight infusion chamber which contains a first chamber for the heated brew water and a second chamber preferably in the form of a nylon fabric bag, for the coffee grains. Thus during operation for a specific preset brewing time the water is allowed to pass freely through the walls of the coffee bag so that the flavour can be extracted evenly, and does not depend on the degree of fineness of the coffee grains or filter mesh. The water chamber is provided with an electric heating element which keeps the temperature constant just below boiling point until the required infusion time has expired. At this point a valve mounted at the bottom of the infusion chamber opens to allow the finished drink to drain off into a jug mounted beneath.

Title: Winter tyres with adjustable studs - has electrical connection to tyre studs enabling position to be controlled by driver
Inventor: WENDT WOLFGANG
IPC: B60C11/16
Filed: 1975-01-07
Abstract: The typre obviates the need to change to special winter tyres when snow or ice is encountered and enables the driver to adjust the position of the studs on the tyres during the journey. The tyre has steel spiles that are perpendicular, horizontal or at an angle to the tyre tread. The studs or spikes are connected by fine gauge wire (protected against short circuiting) to a power source. This can be a small inertia battery with quick-silver filling that generates sufficient electricity by means of the centrifugal force. Alternatively external mechnical means can be used to adjust the stud position. A multi position switch operated by the driver controls the stud position. A lamp or audible indicator can be used to remind the driver when the studs are in the exposed position.

Title: Transporter belt tension measuring device - has belt deflecting rollers and transducers with measuring roller
Inventor: JUENGEL HEINRICH DIPL ING
IPC: G01L5/10
Filed: 1975-02-07
Abstract: The device has two guide rollers and a measuring roller.

Title: Safety catch for automatic trailer coupling - has spring loaded locking slider and floating securing catch
IPC: B62D53/12
Filed: 1975-02-26
Abstract: The safety coupling for an articulated trailer has a catch (6) in a floating mount inside the slot of the coupling plate. The catch pivots by being attached to a linkage and its swing is limited by stops. A set of operating levers (11, 14) lead to a hand operated control (21) outside the coupling and push a wedge lever (7) beside the catch to lock it. When the coupling is released the lever is pulled out of the locking position by operating the hand control, and securing the hand control lever using a ratchet slot (21, 22). The catch moves into the open position. When the new trailer coupling pin in moved into the jaw it presses on the catch, to release the spring loaded levers and pivot the catch and blocking levers into the secured position.

Title: Constant speed electric motor drive - is sequentially switched between drive mode and back EMF measurement mode
Inventor: SAUL GERALD DIPL ING ING GRAD
IPC: H02P7/298
Filed: 1975-07-30
Abstract: Sequential control is used where the controlled variable can be measured and driven at sequential repreated intervals, determined by a clock circuit. A constant speed motor, for example, can be alternately driven, then its back e.m.f. measured, and the drive pulses are arranged to produce a constant speed regardless of load. A measurement and drive phase and their independent circuits can thus be defined. The drive phase circuitry normally comprises a controller and a drive circuit. The measurement phase circuitry comprises a set point generator, comparator, controller and measurement circuit. Feed forward networks, shaping networks storage and nonlinear switching networks may also be incorporated in the measurement phase circuitry.

Title: Induction heating element using separate coils - is to generate fundamental and third harmonic resonant circuits to provide uniform cylindrical type electro-magnetic field
Inventor: DOETSCH HANS-PETER
IPC: H05B6/06
Filed: 1975-09-26
Abstract: An induction heating system, particularly suited for kilns handling a stack of plates, uses two separate coils to generate an approximation to a uniform cylindrical electromagnetic field. The stack of plates (1) is located within a concentric cylindrical coil (2) that coupled with a capacitor to form a resonating circuit operating at the fundamental harmonic frequency. Two counter-wound coils (2, 4) are diametrically located and are coupled to capacitors to operate at the third harmonic frequency. The resulting electromagnetic field is approx. cylindrical in form and results in a rapid heating period. A further improvement in the field structure may be achieved by using four coils for the third harmonic, each displaced by 90 degrees from each other.
