Title: Tamper proof cap for fastening nut - has cap snap fit in base held non rotatably beneath nut
Inventor: PETERSEN TOM LINDHARDT
IPC: F16B33/00
Filed: 1975-12-20
Abstract: The element is for the protection of screws or nuts against unauthorized loosening. It consists of a basic section (12), with a disc-shaped part (16), having an aperture for a bolt. One side of the disc has projections, which during assembly, engage into corresponding recesses (10) of a lower part and prevent turning of the basic section. The other side of the basic section has circumferential hollow-cylindrical projections with a groove (24) or a rib, into which a cap (14) may be inserted. The cap has a corresponding cylindrical section (28) with a rib (30) or groove for engagement. Base and/or cap may consists of a semi-hard synthetic material and is flexible, so that the engagement between the two sections is affected via pressing- or hammering-in.

Title: Automatic electron beam adjustment when producing submicron structures - where scanning marks on substrate provide signals for electronic processing
Inventor: BLOCHBERGER PETER DIPL PHYS
IPC: H01J37/304
Filed: 1975-12-30
Abstract: An electron beam is rapidly and automatically adjusted with high accuracy in a processing plant w.r.t. reference marks provided on an object sensitive to radiation. When the marks are scanned by the beam, signals are emitted measuring the deviation of the object from its desired position. The improvement is that the deviations are measured in five dimensions (x,y,z,Qx, Qy,), and the scale deviations of the beam deflection are also measured in two directions (x,y); and all the measurements are corrected. For measuring the deviations in position, a number of marks is pref. scanned by the beam and subjected to electronic processing, esp. using one mark for adjustment and the second mark to confirm the correct position and provide data w.r.t. the beam focus. The electronic circuit pref. includes one or two low-pass filters; a peak value meter for storing the max. signal value; a converter providing digital signals; and a digital computer. Continuous, automatic compensation for drift etc. is achieved when using an electron beam to produce structures in the sub-micron range, where one structure can be exactly aligned above another, e.g. in microcircuits.

Title: Circuit detecting connection request in telephone system - scans subscriber lines by brief closing of contacts which remain closed if loop is unbroken
Inventor: KOFLER CHRISTIAN
IPC: H04Q3/00
Filed: 1976-05-28
Abstract: The circuit detects a connection request in a telephone system. The request is detected by an indicator allocated to a subscriber and affected by the subscriber line state. The subscriber station can be connected to a connecting circuit supplying it and receiving its criteria. A central scanning and control device cyclically tests indication devices and processes switching states or criteria marking engagement state. A single switch can be connected to a group of subscriber lines as indication device through contacts individually allocated to each line of the group and operated in accordance with engagement state. Central control keeps the switch circuit open by operation of contacts until the "loop closed" state is registered during consecutive brief switching through of contacts by the connecting circuit.

Title: Foil insulation for nuclear plant - has spacing dimples and lapped edges, giving lightweight construction without gaps
Inventor: FRICKER WOLFGANG PETER KURT
IPC: F16L59/08
Filed: 1976-06-02
Abstract: Thermal insulation consisting of metal foil is esp. intended for nuclear installations and consists of a number of spaced, metal foil layers imprisoning air between them; the arrangement is capable of accommodating thermal movements. Some or all of the metal foil sheets comprise embossed projections which forms virtual point contacts between the sheet of foil and the adjacent sheet. Pref. each alternate metal foil has embossed projections on both sides; and a perforated intermediate sheet is incorporated between other sheets, the perforations being fitted over the embossed projections. Minimal contact area between one sheet and the next is attained and, by staggering the embossed points from one sheet to another, a long thermal conduction path is ensured, resulting in the min. loss of insulating value. Gaps do not open up in the sheets due to thermal movement. Fixing is easy.

Title: Magnesium determn. in body fluids e.g. serum or blood plasma - using xylidyl blue in an aq. soln. of a water miscible organic base, pref. an ethanolamine
Inventor: FRIED RUDOLF DR
IPC: G01N33/84
Filed: 1976-08-02
Abstract: Determn. of magnesium in body fluids comprises measuring the change in extinction which occurs on addn. of magnesium ions to a xylidyl blue reagent in alkaline medium. Instead of ethanol as solvent for the xylidyl blue, there is used a water-miscible organic base in 20-80% (pref. 25-50%) aq. soln. Xylidyl blue is readily soluble in the solvent; refluxing is not required for the preparation of the reagent. The reagent has unlimited stability in concentrated form, and is stable for more than 3 months in diluted form. Serum protein is soluble in the solvent, so that no opalescene or turbidity occurs and a serum blank is not required. The reagent (after dilution) has the alkaline pH required for the determination, so that addition of buffer is unnecessary.

Title: Ballasted drive wheel for tractor - has heavy ballast particles mixed with fine plastics-granular bed
Inventor: ECKER SEN LUDWIG
IPC: B60B15/28
Filed: 1976-10-23
Abstract: The drive wheel of the tractor is filled with a mixture of granular ballast and a finer plastics mixture, and with some amount of compressed air. No separate inner tube is required nor any expensive additives such as anti-freeze. The ballast provides an even loading of the wheel with improved stability, and with the loading chosen by the amount of granular ballast. The granular ballast can be gravel while the plastic powder is lighter than water to spread the loading. The addition of compressed air provides some degree of comfort while preventing tyre damage when running over sharp edges.
