Patent DE-2641412-A1 (DE)
Title: Remote supply system for strongly branched cable network - with voltage distributed over balanced two-core cable and voltage stabilised by transformer unit
Inventor: TOLLRIAN HERWIG ING GRAD
IPC: H04B3/44
Filed: 1976-09-15
Abstract: The remote supply system cable network transmits several signals, pref. t.v. signals. Repeaters in series with the signals are provided as loads supplied from a supply point. The distance supply consists of a balanced two-core cable carrying a.c. voltage of about 950 V, and the loads are connected through similar controller supply units to the double core cable. The distance supply voltage is generated by transformation of the 220 V mains voltage, maintained constant by a transformer type voltage stabiliser.

Title: Coupling for tractor hitch - has angled guides and pivoted hook with securing catch on upper fixed arm
Inventor: GOEBEL HANS DIPL ING
IPC: B60D1/46
Filed: 1976-10-13
Abstract: The coupling jaws for the tractor hitch have a pivoted hook (13) lever (2) which is used to raise the towbar of the single axled trailer, and lateral guide jaws (3) to guide the towbar into position. The coupling to the towing arm (1)is by a slot and pin (10) coupling to the guide jaws. A securing catch (4) on the upper, fixed arm prevents the towbar from falling off the towing hook. If the trailer is ot have extra freedom to swing on the hitch then an extension arm on the upper part of the hitch provides a pivot pin for the towbar further back from the hitch, while the guide laws are swung through 90 deg. and bolted into a storage position.
Patent DE-2650083-A1 (DE)
Title: non-porous silicon nitride mouldings prodn. - by moulding silicon powder and silicone resin binder, opt. hardening and nitriding
Inventor: TANK EGGERT DIPL ING
IPC: C04B35/591
Filed: 1976-10-30
Abstract: Prodn. of Si nitride work pieces involves forming a plastic mixt. of Si powder and an organic binder and opt. hardening in air or an inert protective atmos. at ca. 250 degrees C and then nitriding in a nitrogen atmos. at up to 1400 degrees C. The novelty is that the binder is a silicone resin, which remains in the green moulding on hardening and is nitrided with this. Pref. the green moulding is machined by turning before nitriding. The physical and chemical properties of the binder are changed by heating to 300-1100 degrees C, pref. in air or a protective gas, esp. nitrogen, before nitriding. The work pieces are used esp. as matrix structures for regenerators and recuperators for gas turbine plants. The green moulding has satisfactory strength and very complex moulding can be made without the use of a special adhesive, since individual parts adhere when pressed together and sinter to a monolithic prod. Since the binder remains in the moulding pore formation is avoided.

Title: Air flow opening to working areas - has flow controlled rib arrangement ensuring regulated uniform air flow
Inventor: PIEDERSTORFER JOSEF
IPC: F24F13/06
Filed: 1976-12-13
Abstract: The air flow opening is used for supplying air into a working or dwelling area. Air is supplied independently of environment influences to room areas without restricting the freedom of movement and action of the user. The air flow opening has flexible closing ribs. The form of this system is determined by the pressure or by additional stiffening of the ribs. The air flow apertures within the system are smaller than one square millimetre. These apertures are formed by organic or inorganic fibres. The air flow regulator of this type is connected to air supply channel by a rigid nozzle. These outlt openings are arranged into a pattern of air supply channels so that all working places under channels are supplied with air.

Title: Lightweight hot plate for heating precooked foods - has diffusor plate above heating elements with expansion gap covered by plastics foil
Inventor: MUELLER PAUL C
IPC: H05B3/72
Filed: 1977-02-03
Abstract: The lightweight hot plate, esp. for heating up precooked foods comprises a housing contg. the heat generator and a sheet metal plate (4) let into a recess in the lid of this housing to serve as the intermediate element between the heater and the food container.

Title: Cutting edge adjustment of turning tool - is achieved by pointed grub screws engaging sides of conical recesses
Inventor: WERTHWEIN GUSTAV
IPC: B23B27/16
Filed: 1978-12-15
Abstract: A turning tool has a body (21) with a diamond shaped hard metal cutting edge (24) which is retained by a screw (25).

Title: Cast insulator with ribs of high thermal conductivity - which are of higher density around lower density trunk and made by centrifugal casting
Inventor: SILBERMANN ERICH ING GRAD
IPC: H01B19/00
Filed: 1979-01-16
Abstract: The insulator has a cast trunk (2) of low density and low heat capacity, and ribs (4) of insulating material of good thermal conductivity. The insulator is made by centrifugal casting. To the casting compound is added a material of higher density and greater thermal conductivity. This material is moved to the mould periphery during centrifuging and forms the ribs. The higher density material is preferably an aluminium oxide ceramic or powdered quartz. The advantage lies in ice on the ribs melting and evaporating sooner than ice around the trunk, so that a part of the insulator surface is almost always dry. Higher creep current resistance is also attained.

Title: Cardioactive iso:sorbide 2-nitrate selective prodn. - by reaction of isomannide with tri:fluoromethane:sulphonic acid halide or anhydride and reaction of the prod. with an (in)organic nitrate
IPC: C07D493/04
Filed: 1979-02-02
Abstract: In a new process for the selective prodn. of isosorbide 2-nitrate (I), (A) isomannide is reacted in an organic solvent with an equiv. amt. of a trifluoromethane sulphonyl halide in the presence of an acid binding agent or with the equiv. amt. of trifluoromethanesulphonic acid anhydride, and (B) the resulting isomannide 2-trifluoromethanesulphonate (II) is reacted in the presence of a solvent and opt. with heating either with an alkali(ne earth) nitrate (opt. in the presence of a crown ether or a phase transfer catalyst) or with an organic nitrate. (I) is useful in the treatment of coronary heart diseases, e.g. angina pectoris. It is a metabolite of isosorbide dinitrate, being formed during "first pass" metabolism of this cpd. in the liver. Use of (I) rather than isosorbide dinitrate is likely to minimise inter-patient differences in response attributable to variations in the degree of first pass metabolism. The process gives (I) uncontaminated by prods. nitrated other than in the 2-position.
