Title: Output pulse train determined by two frequencies - uses number of signal elements moved in two rings at specified frequencies and then combined
Inventor: DRAGOTINOV ALEXANDER DIPL ING
IPC: G06F7/60
Filed: 1976-09-24
Abstract: A number (a) out of a total of (m) adjacent signal elements in a certain binary state forming a ring, is stepwise moved in the ring always in the same direction at the first frequency (F1) equal to a specified frequency (f1) or (mf1).

Title: Superficial ornamentation or reinforcement of artificial leather - by pressure and heat applying and embedding non-melting materials
Inventor: GROTH JOACHIM
IPC: D06Q1/00
Filed: 1976-12-24
Abstract: Superficial ornamentation of synthetic leather, as e.g. PVC- film, polyurethane film, polyester film, or similar is effected by means of cuttings or pieces of material which do not melt with the synthetic leather. These are applied under heat and pressure to the surface of the synthetic leather using suitably engraved plates, and are wholly or partly embedded into the substrate. The plasticised synthetic leather is forced by the pressure into the pores, cavities, passages, or undercuttings of the sections or pieces of material, and are bonded on hardening. The non-melting cuttings or pieces may be bonded to the leather by being coated, printed or vapourised on to a carrier film which will melt into the artificial leather. The ornamentation may act simultaneously as a reinforcement. The material embedded may be protected by a ridge or ornamental edge set up on the surface of the leather. The sections or pieces applied may have a protective coating, which may be given a particular structure by the pressing tools, such as graining, grilling, or embossing. Artificial leathers can be given surface structures imitating snake, crocodile, ostrich skins, etc. and be reinforced in the process.

Patent DE-2712577-A1 (DE)
Inventor: OGATA IKUEI
IPC: C07C301/00
Filed: 1977-03-22
Abstract: The anthraquinone sulphuration mixture treated comes from the preparation of anthraquinone- alpha -sulphonic acid by sulphurating anthraquinone in the presence of a metal catalyst comprising a carrier loaded with the metal. The sulphuration mixture is mixed with water and the mixture is treated with hydrogen to reduce a catalyst metal ion dissolved in the aqueous medium to the metal and depositing the metal on the catalyst carrier and for simultaneously converting the  alpha -sulphurated anthraquinone into its leuco form. Unconverted anthraquinone and the metal catalyst in the form of the carrier loaded with the deposited metal are separated from the mixture and recovered. Finally, the  alpha -sulphurated anthraquinone is oxidised from the leuco form to the anthraquinone form with simultaneous precipitation of the latter in the form of the alkali metal salt thereof. The  alpha -sulphurated anthraquinone can be used as a starting material for blue colorants.

Title: Long term solar heated water store - uses two water layers separated by thin light permeable plate or film
Inventor: PLATZ ROLF DIPL CHEM DR
IPC: F24J2/04
Filed: 1977-04-21
Abstract: The process for collecting and long-term storage of solar energy in water, uses two separate zones, positioned above each other. Solar energy is gathered in the base or in the lower water layer by absorption, the water being heated. The lower water layer is separated from the upper one by a light-permeable foil or plate. The upper water layer is thickened by natural or synthetic polymers, for thermal light-permeable insulation of the lower layer upwards. Absorption in the lower layer is improved by using a black foil at its base, or by dying the water.

Title: Protection of reduction-sensitive dyes during pad dyeing and printing - of synthetic fibres, by adding an oxidising agent to the padding bath or printing ink
Inventor: REINHARDT FRIEDRICH DIPL CHEM
IPC: D06P1/667
Filed: 1977-07-05
Abstract: Reduction-sensitive dispersion dyes are protected reduction during pad dyeing or printing of synthetic fibres or mixed synthetic/cellulosic fibres by the addn. of oxidising agents. The oxidising agent used is such that 0.05% aq. soln. has an oxidn. potential of between +200 mV and +30 mV. Oxidising agents satisfying the above requirement give good protection of reduction-sensitive dyes against colour changes during pad dyeing and printing of (mixed) synthetic fibres, which requires a high temp. fixing stage. The named oxidising agents do not cause oxidative degradation of the dyes. The oxidising agent may be e.g. an aromatic organic cpd. contg. a COOH-, SO3H or, PO3H2 gp. together with halogen atoms and one or nitro gps. on te aromatic nucleus; or an alkali- or ammonium salt of meta-vanadic acid iodic acid, peroxydisulphuric acid, soluble salts of Ce(IV) or SeO2. The oxidising agent is used e.g. at 2-50 g/kg printing ink or per 1 padding liquor.

Title: Copy grinding machine for wooden workpieces - drives model and workpiece in sync. manner so that oscillation of machines is controlled
Inventor: SCHMIDT ERICH ING
IPC: B24B17/02
Filed: 1977-09-21

Title: Roof covering with roofing felt-covered polystyrene foam panels - with narrow slots opening out towards roofing felt
Inventor: OLSEN ELBERT
IPC: E04D13/17
Filed: 1977-10-13
Abstract: Roof covering comprises insulation which is adhered to the roof underneath and which consists of polystyrene foam panels covered with roofing felt. The panels comprise narrow slots which open out towards the roofing felt, and which are pref. arranged in a regular pattern. The panels are pref. placed on a supporting layer, with the slots extending as far as the supporting layer. The slots may be rectilinear and extend in one direction or in both the longitudinal and the transverse directions of the panel, or in both the longitudinal and the transverse directions of the panel, or undulating. As stationary air is trapped in the slots and as they are narrow, slitting does not affect the insulating properties. Movements of the panel due to temp. are damped, so that there is no great stress leading to crack formation in the roofing felt.

Title: Buck material bucket wheel sluice valve - has edges shaped to connect each bucket at wheel centre first
Inventor: GRUENER JOHANN ING GRAD
IPC: B65G53/46
Filed: 1978-02-14

The shape of the inlet port edge deviates from that of the buckets, so that in a particular area in the axial direction, flow starts earlier than in the rest. This deviation between the bucket edges (12) and those (14, 15) of the inlet port (8) and/or those (16, 17) of the outlet port (9) is such that connection to each bucket (11) is made earlier at the centre of the wheel (7) than elsewhere.
Patent DE-2816495-A1 (DE)
Inventor: STIEFEL MAX ING GRAD
IPC: G01N9/06
Filed: 1978-04-15
Abstract: The density of liquids is determined by weighing. To determine the density precisely, the liquid flows through the feed line (10) in the direction of the arrow (18) into the weighing container (1) and leaves the latter via the lines (11, 12) in the direction of the arrows (19). Solids contained in the liquid flowing in are predominantly entrained via the lower line (11) because of their higher specific gravity. On the other hand, the gas components rise upwards and are removed predominantly via the upper line (12). <IMAGE>
