Patent DE-2216087-A1 (DE)
Title: Spindle braking - with miniature electro-motor to operate brake lever
IPC: D01H7/22
Filed: 1972-04-01
Abstract: Designed for use on spindles in a spinning or twisting machine, the miniature electro-motor turns a shaft with an eccentric disc so that the brake lever is required to overcome any restraining tension and bear on the spindle brake surface, to bring the spindle to rest. The purpose is to eliminate manual effort in braking the spindles, and eliminating the need for a magnet as in conventional electrical braking systems.

Title: Physiological properties of fresh blood cells - by analysis with coulter counter-type apparatus
Inventor: SCHULZ JUERGEN DR ING
IPC: G01N27/02
Filed: 1973-04-16
Abstract: The props. are determined on a fresh cell suspension in which the resistivity of the analysis liquid is recorded by means of an electric current flowing through the liquid and the subsequent analysis is effected by means of the discrete intensities which impart a notable variation in the resistivity of the liquid. When results are plotted, there is a pronounced elbow on the curve for each type of cell, and it is possible to differentiate between different types of cell. This is impossible after cells have been fixed, e.g., on a slide.

Title: Ammonium vanadate prepd. by controlled pptn. - has low alkali content and gives higher yield when reduced to vanadium
Inventor: THOME ROLAND DR
IPC: C01G31/00
Filed: 1974-03-14
Abstract: of low alkali content is prepd. by precipitating solns. of sodium vanadate and sulphate with ammonium sulphate at pH 7.5 to 9 and at 25-35 degrees C, pref. with vigorous stirring. Higher purity of prod. reduces losses in aluminothermic redn. of V2O5 to vanadium, caused by Na2O, which consumes more Al and is reduced to sodium, which causes the dust produced in the process to contain appreciable amts. of vanadium. Yield in the pptn. is raised from 83% to 97%.
Patent DE-2417429-A1 (DE)
Title: Ceramic tiles with ornamental patterns - formed by rolling grooves into the surface of an extruded blank
Inventor: KECK DIETER
IPC: B28B11/08
Filed: 1974-04-10
Abstract: An ornamental tile made of a ceramic material, esp. clay has, on the front, visible surface of a rectangular blank, notches which form an ornamental pattern, the notches having a wedge-shaped cross-section, the wide end of the notches being on the front surface and having the width of the usual gap used for laying the tiles. The pref. process and device consists of extruding a continuous blank which then passes through a pair of rolls on vertical axes; the surfaces of the two rolls are provided with projections corresponding to the decorative pattern of notches required in the tiles; the blank is extruded edge upwards and hence the pattern is rolled onto its surface. Used, e.g. for floor tiles. The ornamental grooves can be filled with various materials for decorative effects and the pattern is independent of the edges used for laying the tiles; if required, the tiles are easily broken through the grooves if irregular shapes are needed in laying.
Patent DE-2419755-A1 (DE)
Title: Pressure control valve for trailer pneumatic brakes - isolates trailer supply when trailer brake line broken, for hold-off brake operation
Inventor: BECK SIEGFRIED
IPC: B60T15/24
Filed: 1974-04-24
Abstract: The supply line to the trailer pneumatic brakes is protected by a special pressure control valve which is spring loaded and is subjected to the pressures in the two braking systems, i.e. trailer and towing unit. In the event of a leak in the trailer brakes the valve closes so that the trailer brake pressure falls more rapidly than it would if supplied from the towing unit. This enables the automatic hold-off brake to operate rapidly. To increase the brake response, the control valve element can be coupled to a venting valve which vents the line of the trailer brakes. If the trailer is not coupled to the towing unit then the valve operates in any case and is thus prevented from seizing up through non-use and corrosion.

The bearing pins are welded to brake blocks. Pivots which are turned at the ends of the bearing pins protrude at either side of the brake blocks. The pivots are supported in bearings scales which are bolted together. The bearing scales which are nearest to the tubular shaft are welded to the brake support. The dividing plane between the two scales is at right angles to the radius which defines the end of the arc over which a brake block extends.

Title: Water injection in combustion engine - to produce water vapour thus further increasing volume and energy output
Inventor: ARENDT J DIPL ING
IPC: F02B47/02
Filed: 1974-06-20
Abstract: By the injection of water advantage is taken of the heat of combustion which is normally not converted into mechanical energy, but is dissipated by cooling. The amount of water to be injected should be in accordance with the heat produced by combustion of the fuel such that the water vapour generated contributes to the kinetic energy produced. Water may be injected at the moment of ignition or added to the fuel mixture.

Title: Electrolytic condenser prodn with silver film - for soldering the cathode terminal without flux using silver suspension in organic solvent
Inventor: BUB HUBERTUS
IPC: H01G9/04
Filed: 1974-09-21
Abstract: In the prodn. of electrolytic condensers by applying a Ag coating to a valve metal part, with a dielectric and a semiconductive coating, and soldering this to the cathode terminal, the Ag coating is applied by dipping the part in a suspension of Ag in an organic solvent and baking at elevated temp. and then the cathode terminal is soldered to the Ag coating, without flux. Detriment to the condenser due to humidity, voltage and temp is avoided and prodn. is simplified. Dipping in a graphite emulsion and the use of flux, which can easily cause contamination, are eliminated. Z values approaching the theoretical Z value of the condenser can be obtd. Other electrical properties are also influenced favourably, e.g. noise potential, tan delta and temp. dependence of the Z value. The process can be used in mass prodn.

Abstract: The panelling or paving block (1) esp. a concrete block, has a right-angled surface area made up from three squares with outer and/or inner corners reduced, with variable block height. In this case there is a diminution of the top surface, carried out in a part-circle arc shape across the two corner slopes, so as to produce a corner stone with a rounded corner decorative effect. The inside rounding of the decorative reduction may be in the dorm of an arc with its centre on the trimmed square corner. The decorative reduction may be of minimal size in relation to the height (h) of the block, and rounded off at the edges. Many variations are possible in using blocks of this type for an ornamental effect.
