Title: Hollow plate for gas fired boiler shell - incorporates pattern of raised ribs with bosses throttling flue gases
Inventor: SCHOENECK OTWIN
IPC: F24H1/38
Filed: 1978-06-12
Abstract: The shell of a gas fired boiler is made from hollow plates each with a water inlet (2) and water outlet (3) at diagonally opposite corners.

Title: Valve with circular rest slider - has wedge shaped barrier plate and spectacle part acting in wedge shaped slot
Inventor: WOLTER HEINRICH
IPC: F16K3/14
Filed: 1978-06-30
Abstract: The pipe valve with a double circular slider with circular rest is particularly for use at high temperatures. It has a barrier plate and a spectacle in a common frame sliding at right angles to the pipe. In the shut position the plate is moved via a slot into the free cross-section of the pipe, while when open the spectacle acts as a slot seal in the pipe wall.

Title: Removal of contaminants from exhaust gas streams - using injection of chemical adsorbent which is reacted in co-current reactor, the cross=sectional area or which can be adjusted
Inventor: ROTHE GUENTER DIPL ING
IPC: B01D53/68
Filed: 1978-09-11
Abstract: Contaminants in exhaust gas streams are removed by injecting solid additives such as alumina, calcium compds. or similar. These are removed in a subsequent separator. The gas and solids are contacted in a co-current reactor. This reactor has a flexible wall on one side which allows the cross-sectional area to be altered. This in turn alters the flow velocity and does not allow it to drop below a minimum of 4 m/s, maintaining suspension of the solids and an adequate residence time. Used for cleaning exhaust gas streams esp. to remove halogens or halogenated hydrocarbons. Allows the additive particles to be maintained in suspension in the gas stream together with a mechanism for controlling the velocity through the contact column.

Title: Assembly measuring test-piece dimensions - uses flexible mechanical sensor with threshold force transducer and photoelectric position transducers
Inventor: WILLHELM JOERG DIPL ING DR ING
IPC: G01L5/22
Filed: 1978-09-23
Abstract: The assembly measures test piece dimensions using a mechanical sensor and photo-electric position transducers. The test piece is fixed onto a movable table whose position is recorded by the photo-electric transducers. The moving test piece touches the feeler and a force transducer in the feeler head stops the table when a threshold force is reached. The feeler's head position is recorded by the relevant position transducer. The data is stored in a computer which compensates for the feeler deflection to determine the exact test piece location.

Title: Magnetic wedges for electric motors - are made on mandrel with parallel projection inserted in stator, with wedges produced by injection
Inventor: OHYA IKUO
IPC: G01C9/18
Filed: 1979-03-19
Abstract: The unit is produced in a first operation, consisting of stator laminations and a winding embedded in an insulating plastic synthetic resin, using case shaped elements enclosing the stator laminations and coils. A cylindrical inner shaped element with parallel projections is inserted into the cylindrical bore in the stator laminations, thus producing wedge grooves in the open parts of the slots. In a second operation magnetic wedges are produced by direct injection of a mixture of 60-95w.% of magnetic powder and 40-5w.% of a synthetic resin. Thus the magnetic wedges have smooth, concave surfaces fitting the slots.

Title: Safety shutter for two pin socket outlet - uses permanent magnets to provide force for closing shutter when plug is withdrawn
Inventor: KULLIK GUENTER R J
IPC: H01R13/447
Filed: 1979-06-27
Abstract: The shutter arrangement comprises two parts, a stationary guide plate (13) and a shutter plate (20), which fit into the recess of a standard two pin outlet. The shutter plate is free to move on guide rails in the stationary plate. Both plates are made of permanent magnet material which can be injection moulded. Alternatively, permanent magnet inserts are contained within a normal moulding. The magnet (32,33,38,39) polarities are arranged such that a stable condition obtains when the shutter (20) is in the closed position. To insert a plug the pins are entered into holes in the shutter and the latter pushed down to permit entry into the socket outlet. In this position like poles face each other on the shutter and stationary plate to give the necessary resetting force when the plug is withdrawn.

Title: Direction-speed control for steam driven model locomotive - uses track voltage to control reversing gear and regulator servos
Inventor: FREESE JENS
IPC: A63H19/24
Filed: 1979-08-03
Abstract: The direction and speed of a steam driven model locomotive, running on a track with rails insulated from each other, is controlled by the polarity and voltage of DC applied between the rails. The locomotive carries a battery and a controller for two servo motors driving the reversing gear and regulator. Shoes pick up the control voltage from the rails. A potentiometer on the reversing gear supplies a voltage whose polarity depends on its setting. This is compared with the track polarity and the servo motor accordingly runs to one limit or the other. Another potentiometer on the regulator supplies a voltage proportional to opening and this is compared with the track voltage. The regulator servo motor runs in the appropriate direction to reduce the difference to zero.
Patent DE-2938914-A1 (DE)
Title: Adjustable slatted venetian blind - has winding tube as shaft for blind raising, driven by helical spring
Inventor: SCHUSTER HARTWIG
IPC: E06B9/32
Filed: 1979-09-26
Abstract: The operation is simplified as compared with that for a standard draw cord system, while construction is less expensive than that for gearing or motor drive, on a venetian blind with adjustable lamellae. Drawing up lamellae is effected by a winding tube, with helical spring drive. The tube, serving as the spring shaft, can be used alone, or in conjunction with a top rail. Winding spools, or other guides for strips, may be fitted for improved draw cord guidance. The spiral spring force can be directly transmitted to the spool or rollers. This combines the simplicity of the spring roller blind with the advantages of regulated protection from sun and glare.

Title: Automatic adjusting method for two structures in parallel planes - using sensors and markings on opposite planes to detect correspondence
Inventor: TREML HANS
IPC: G03F9/00
Filed: 1979-10-24
Abstract: The automatic adjusting process is esp. suitable for the prodn. of integrated semiconductor circuits using lithographic processing stages. Mask (3) structures are transmitted to a radiation-sensitive, doped layer of a semiconductor crystal wafer (1). Complementary markings (4,6) are used for the adjusting in both planes. Sensors (6) are integrated in or on one of the planes so that, by a corresp. marking in the opposite plane, a correspondence between the relative position of the planes and the sensor signals is formed. The sensors can be produced by thin film technology. Electrical contacts can be brought to the mask edge by conductive paths. From here the measuring signal is conducted to measuring electronic circuitry. Differential photo diodes can be used as the sensors, the adjusting being carried out by light adding and difference measurements.

Title: Oxygen enrichment device for surface waters - by air injection through rising spiral to sepn. chamber
Inventor: WERWITZKE EBERHARD
IPC: B01F3/04
Filed: 1979-12-20
Abstract: A device for the oxygen enrichment of surface waters consists of a vertical larger-dia. tube with a smaller-dia. tubular spiral inside. The spiral has at the bottom and several nozzles for the inlet of compressed air which cause the water to rise up to a sepn. chamber. Air escapes from a vent and the oxygenated water drops through a downcomer return pipe to the bottom. This is a simple device which dissolves a large proportion of oxygen in the water and leaves the natural water layers undisturbed, by enriching mainly the bottom strata with oxygen.
