Patent DE-2015736-A1 (DE)
Title: Handling detectors for valuabler etc
IPC: G01L1/06
Filed: 1970-04-02
Abstract: The device used to detect unauthorized or unsupervised handling of tools etc. The object is coated with a film consisting of a volatile carrier, a polymer binder and a plurality of micro capsules which contain a contact indication liquid. The volatile component is evaporated to leave the capsules wholly or partially embedded in the binder to form the film over the whole surface. Any contact with the object breaks the capsules and releases the indicator/detector fluid. A non water soluble dye may be used for the latter in globule sizes 5-500 mu.

Patent DE-2037116-A1 (DE)
Title: Spot arc welding - of zinc-plated sheets without damaging coating on spot periphery
IPC: B23K9/007
Filed: 1970-07-27
Abstract: When zinc-plated sheets are to be joined by spots of arc welding, the coating is easily destroyed at the periphery of the weld pool of molten metal, thus requiring additional corrosion protective measures. This can be saved if a bush of a heat-conductive metal of somewhat larger bore than the intended welded spot is pressed on the surface and the welded spot is produced inside it. The bush carries away enough of the heat to avoid any damage to the coating.
Patent DE-2042184-A1 (DE)
Title: Removal of metal, sulphur and nitrogen - impurities from hydrocarbon charges
Inventor: GRENVILLE MYERS CLAUDE
IPC: C10G65/04
Filed: 1970-08-25
Abstract: The charge is contacted with a catalyst at 340 degrees-485 degrees in the presence of H2. the catalyst contains a hydrogenation constituent with an activity of 0.2-8.0 and is compounded with a porous support. The exit gas is then contacted, at >399 degrees C and in the presence of H2 with a catalyst which is bound to a porous support and which contains a hydrogenation constituent. Preferably each contacting is made in a flow bed or a boiling bed. Preferably, the charge is a raw oil with a full boiling range, coke-oven gas or a light or heavy vacuum gas oil. Advantage is that greater removal of impurities is achieved; and process is relatively cheap.
Patent DE-2053180-A1 (DE)
Title: Pouring control in a casting system - with magnetic field inducer to rotate molten metal against supply
IPC: B22D39/00
Filed: 1970-10-29
Abstract: The rotation of the molten metal in the supply container, located between the molten metal vessel and the mould, exerts centrifugal force against the gravity feed of metal, preventing it from entering the supply container. If the magnetic field is weakened, the centrifugal force is reduced allowing metal to enter and overflow, thus giving a controlled pouring action.

Patent DE-2135735-A1 (DE)
Title: Screw press - for pulp in continuous cellulose triacetate prodn with sprung flap and liquid collection
Inventor: MICHAL SKIJ FJODOR MICHAJLOWIT
IPC: C08B17/02
Filed: 1971-07-16
Abstract: At the outlet end of the screw press, a flap is sprung against the direction of material travel so that the pressure of the mass causes the flap to move back to expose an outlet aperture. The pressure forces any residual liquid to pass through a perforated plate into a collection chamber, while the pulpy mass passes out of the press. The purpose is to provide a liquid extraction system while the mass passes from stage to stage in a continuous prodn. cycle, with the minimum loss of fibre material and safe for operators.
Patent DE-2139163-A1 (DE)
Title: Triglycerides determination - by saponifying oxidizing to formaldehyde, and reacting with ammonia and acetylacetone
Inventor: FRIED RUDOLF DR RER NAT
IPC: G01N33/92
Filed: 1971-08-05
Abstract: Triglycerides in e.g. serum are determined by a procedure in which glycerol is released from the triglycerides by saponification and then is oxidised to HCHO, and the resulting HCHO is reacted with NH3 and a stable, water- and alcohol-soluble, colourless metal complex (pref. an alkali(ne eart) complex) of acetylacetone so as to give 3,5-diacetyl-1,4-dihydrolutidine (I). Pref. the reagent soln. which is reacted with the HCHO is a 1-10% soln. of a metal complex of acetylacetone in a 5-30% aq. soln. of an ammonium salt. Use of acetylacetone in complexed form gives a stabilised reagent which is still sufficiently reactive to give the desired coloured cpd. (I) with NH3 and HCHO.

Title: Gas scrubbing - removes by diffusion into froth particles below 1/4000 mm
Inventor: HUPPKE GLEN P
IPC: B01D47/02
Filed: 1972-06-29
Abstract: Scrubbing method and appts. for industrial gases removes substantially particles below 1/4000 mm. and even in submicron range. Gas flows at high velocity through running sheet of frothing agent containing washing liq., followed by sufficient residence of the gas in the bubbles so formed to ensure thorough wetting out by and diffusion into the washing liq. of the contamination. Froth is then destroyed, separating contamination contg. washing liq. from cleansed gas. Washing liq. properties are adjusted to give pref. small bubble size. Excess wash liq. carried along during frothing is drained by making bubbles travel upwards upon inclined surface. Speciclay-out for such scrubber is claimed.

Title: Partial lining disc brake - has U-shaped spring arranged to give high pre-stress and error proof fitting
Inventor: CASPER EDUARD
IPC: F16D55/226
Filed: 1973-09-11
Abstract: Designs prior to the present one envisaged for holding the pad in place a U-shaped spring, one arm of which extends through axial openings of the brake frame, the lower part of the second arm resting on the brake frame and the top part of the second arm resting radially against the brake tongue. This arrangement has error possibilities during the fitting when the spring does not come to rest on the surface provided on the braking tongue but tangentially in a place adjacent to the brake tongue. In such case the spring becomes ineffective. The present design envisages the use of two brake tongues with high pre stress force. They can be inserted into the brake holder before the fitting of the brake tongue.

Title: Deep fat fryer with automatic turning means - comprises series of strips controlled by a rod to rotate upwards
IPC: A47J37/12
Filed: 1975-02-21
Abstract: The deep far fryer has an oil trough with several parallel strips intended to support the articles to be cooked, e.g. doughnuts and these strips are each designed to rotate about an axis parallel to their longitudinal axis from a horizontal into a vertical position, which causes the larger part of the upwardly facing surfaces of the strips to rise. The basket or tray is designed with slots by means of which it can be inserted and removed from the trough when the strips are vertical. First the doughnuts are placed on the strips which are in the horizontal positin until they have been cooked sufficiently on one side whereupon all the strips are brought simultaneously into the vertical position so that the doughnuts roll down onto the basket tray which has already been inserted and are thus turned over.
