Patent DE-2356628-A1 (DE)
Title: Comparison and indicating system for binary numbers - with both equivalence and non-equivalence comparison
Inventor: MUTH KLAUS DIPL ING
IPC: G06F7/02
Filed: 1973-11-13
Abstract: A non-equivalence gate for each binary number position compares the corresponding digits of the two numbers and only produces a one output on non-equivalence. A switch can have a zero or a one signal at its output depending on its position. Each non-equivalence gate is in series with a second non-equivalence gate having one input connected to the output of the first gate and the other input connected to the switch output, so that in the zero switch position the numbers are subjected to a non-equivalence comparison and in the one position to an equivalence comparison. The outputs of the second gates are connected to separate indicators, pref. light emitting diodes.

Title: Siphon-operated pipette-rinsing appts. - with conical support plate allowing full bore rinsing
Inventor: MEISER PAUL
IPC: B01L99/00
Filed: 1974-03-02
Abstract: A pipette-rinsing device, comprises a rinsing vessel with a siphon tube outlet and a cross section or filling support plate on which the free ends of the capillary tubes of the pipettes inserted in the vessel are supported. The support plate slopes down to a flow aperture of reduced cross section compared to that of the rinsing vessel and an attachment is provided in the zone above the flow aperture which supports the pipette capillary tubes laterally and secures the pipettes against sliding down the sloping support plate, in a position in which the ends of the pipette capillaries, located near the edge of the flow aperture rest only with the rim tangential to the sloping support plate. The appts. permits a much greater rinsing rate in the pipettes and therefore more efficient cleaning, due to the pipette tip outlets being almost completely unobstructed in comparison with the known equipment using a perforated support plate or wire mesh support.

Title: Gaseous fuel from waste - produced by low temp. carbonisation and gasification of the coke
Inventor: KIENER KARL DIPL ING
IPC: C10J3/00
Filed: 1974-07-04
Abstract: A gaseous fuel is prod. from waste materials such as household and industrial refuse, old tyres, scrap plastic etc., by (a) low temperature carbonisation of the waste in the absence of air at 300 degrees - 600 degrees C and preferably 400 degrees - 500 degrees C and (b) drawing the carbonisation gases so obtained continuously through a red hot reaction bed produced from the resultant low temperature coke and a feed of pre-heated fresh air, so as to convert these gases to a high energy gaseous fuel. More especially, the coke from the carbonisation step is separated from incombustible waste before supply to the reaction bed. A gas of sufficient calorific value for running an internal combustion engine can be produced, with little or no supply of external heat, without causing atmospheric pollution, at a favourable cost.

Title: Housing for telex or typewriter with tape unit - has keyboard which is displaced to one side to leave space for auxiliary unit
Inventor: VORBACH GUENTHER
IPC: B41J29/02
Filed: 1974-09-10
Abstract: The side of the housing (1) adjacent to the space for the auxiliary equipment (e.g. 10) has reception guides which may be used to facilitate the attachment of additional equipment e.g. a series of punched tape units (13). There is an upper groove (7) above or within the keyboard which incorporates a row of keys (8) for inputting special functional commands and control commands. In the case of punched tape equipment, the tape can be fed through a channel (12) to the tape read unit (10). This design of housing is simple in construction but permits bulky auxiliary equipment to be selectively attached to the main machine external to the housing.

Title: Mobile blender for gaseous fluids, esp. beer, from containers - three-inlet structure can be combined with other
Inventor: ESAU KLAUS
IPC: B67D1/00
Filed: 1974-09-10
Abstract: A mobile engine, mounted on a trolley, for receiving beer or some other gasified liq. from a number of containers, has parallel inlet pipes in the form of a "U" laid on its side. The inlet pipes have a horizontal leg joining a vertically rising leg which turns at right angles into a second horizontal leg parallel to the first and extends through a tee to form a rectangle with a vertically descending outlet pipe. Above the junction of the inlet and the outlet pipe on the upper leg of the tee there is a sight glass with an air bleeder valve, and below it, running at right angles to the horizontal inlet legs, above the hose fittings, there is a collector pipe into which the outlet pipes open through remote controlled valves. Each inlet pipe has monitors generating signals corresponding to the rates of flow, density of the liq., etc., and approx. at the height of the sight glass a control cabinet for regulating the valves according to the signals addressed to it from the monitors, is supported close to the horizontal legs of the inlet pipes. An efficient, compact and flexible layout with a low centre of gravity ruling out the risk of overbalancing.
Patent DE-2446481-A1 (DE)
Title: Spray cooling for continuous bar casting - using recycle jets to simplify variations in coolant throughput
Inventor: SCHICKETANZ WILHELM
IPC: B22D11/124
Filed: 1974-09-28
Abstract: Secondary cooling for continuous casting operations uses coolant sprayed onto the emerging bar or ingot, this being sprayed from recycle jets which are equipped with purpose built jets to adjust the water spray to any required condition. The jets provide a flat, fan shaped spray. The process is for use in continuous casting of steel for making wire bars on forging ingots. Depending on the steel and the type of product to be made, the secondary cooling applied as the steel emerges from the mould varies. Using conventional jets, a product change can mean a time and labour consuming operation to change jets. With the recycle jet, variations in throughpu of up to 10:1 can be achieved without change in the supply pressure of the cooling water merely by controlling the amount of recycle or of its pressure. Preferably, full cone sprays are needed and recycle sprays are hollow cone. This problem is overcome by using flat fan type sprays.
Patent DE-2446763-A1 (DE)
Title: Filter consisting of dielectric plate - has metallisations on two main surfaces and two opposite edges
Inventor: KROCKOW HELMUT ING GRAD
IPC: H01P1/203
Filed: 1974-08-17
Abstract: Metallisation on one of the main sides of the dielectric plate is divided by leakage paths near the edges in three parts. A ferro-magnetic layer is applied on the opposite metallised surface. The plate is preferably rectangular and can be connected directly to a circuit without additional connecting means e.g. by a dip soldering process. The metallisation of one main surface comprises an electrode surface (4) and two smaller partial surfaces (5) joined via leakage paths (9) near the corners (7) of the metallised narrow surfaces (3). The second main surface (2) is completely covered by a metallisation (6). A ferro-magnetic layer (8) increases the inductance.

Title: Constructional member for playground slide - rests directly on hill-side surface and is held down by spikes
Inventor: WIEGAND JOSEF
IPC: A63G21/00
Filed: 1974-11-12
Abstract: The children's playground style slide is intended to run down the slope of an Alpine valley (perhaps 1,000m) and is more robust than asbestos-cement, pylon-supported examples. The constructional member consists of a metal trough (1) supported on a concrete base (3) with the metal edges bent downwards over the sides of the concrete (2).

Title: Control of liberated steam in aluminium oxide prodn. - during the stepwise expansion of extd. slurry
Inventor: ORBAN FERENCE DIPL CHEM
IPC: C01F7/0666
Filed: 1974-12-31
Abstract: In the quantitative control of the steam liberated in the course of Al2O3 prod. during the stepwise expansion of the extracted slurry in the expansion vessel, and used for the stepwise preheating of the bauxite ore, the level of the condensate in the tubular heating system of the pre-heater units heated by the steam liberated in the expansion vessels is regulated, esp. as a function of the difference between inlet and outlet temp. of the sludge entering and leaving the appropriate pre-heater. Method ensures the min. use of high pressure steam and prevents the contamination of the steam by entrained slurry so taht fouling of the steam side heat exchange surface in the pre-heater is avoided and the mean heat transfer value increases, thereby increasing the capacity of the equipment and lowering the alkalinity of the condensate.
