Patent DE-2313615-A1 (DE)
Title: Temporary fixing tack - with elastic sleeve friction fitted under tack head
Inventor: OIDE KUNIMASA
IPC: E04F13/08
Filed: 1973-03-19
Abstract: Tack has a nail stem unitary with a nail head and a cylindrical elastic sleeve surrounding and coaxial with the stem in a snug-slide fashion, the sleeve being of greater outside dia. than the nail head but less than 1 mm and the length being >=4mm but less than the nail stem. Used for tacking decorative boards to a structure temporarily while a bonding adhesive sets. Elastic sleeves provide resilient pressure to the decorative board, holding it in good contact with the structure while the adhesive sets. The tacks allows fixing by small dia. nails, reducing damage to the surface, and are also easy to remove.

Abstract: The article is produced by applying an ageing and high temp. hardening treatment to a high alloy workpiece of compsn. (wt%) 1C, 0.5-25 or 20-60 of Ni and/or Co, 9-30 of Cr and/or V, bal. Fe. Pref. the casting is formed into a workpiece which is heated in sections to 450-980 degrees C, pref. at 1050-1350 degrees C followed by heating at 850-950 degrees C until these sections have changed to a magnetic structure after which the workpiece is cooled in a magnetic field. It is then heated in sections, which are required to have non-magnetic properties, to a temp. range of 1000 degrees to m.p. and cooled sufficiently rapidly so as to prevent the formation of a magnetic structure. A low temp. hardening treatment may be finally be applied.

Title: Granular treatment bed uniformly maintained during settlement - by pressing grating into surface to subdivide it into cells
Inventor: ROGGE KARL
IPC: B01J8/00
Filed: 1973-07-14
Abstract: A method of producing and maintaining a uniform surface on a bed of granulate and consequently a uniform bed depth, in adsorption, filtration and catalytic plants, consists of applying a grid of vertical partition walls of suitable depth and spacing, so as to sub-divide the surface of the bed into a large number of cells.

Title: Magnetically operated locking mechanism - has locking bolt movable transversely to movement of control element
Inventor: HALLMANN HERMANN
IPC: E05B47/00
Filed: 1973-10-10

Title: Electro drive for cars - carries batteries in two counter-rotating flywheels with cardan transmission onto the car wheels
Inventor: HIMMEL JOSEF
IPC: B60K1/04
Filed: 1974-01-19
Abstract: By arranging the batteries into the flywheels enough inertia mass is obtained without having to carry additional dead weight in the vehicle. One in motion the flywheels keep spinning even at the frequent standstills of the car, resulting in reduction of power consumption with additional benefit of space saving. The counter-rotating operation of the flywheels has a stabilising effect with inherent good road holding qualities. The electric drive of the flywheels serves at the same times as a drive for the motion of the car without the use of a separate motor. The entire assembly can be housed in a weather-protected compartment with easy access for battery change.

Title: Balanced ratio detector with semiconductor - has each diode with linearising resistor connected in series with it
Inventor: WELLHAUSEN HEINZ DIPL ING
IPC: H03D3/10

Abstract: The symmetrical ratio detector utilises semi-conductor diodes in conjunction with resistors. These resistors are such, that the diode capacitance calculated for the respective diode-resistor circuit is approx. independent from unwanted dynamic capacitance changes due to amplitude fluctuations. An additional capacitance is in parallel with each diode. The optimum capacitance and resistance for given circuit components may be derived from algebraic expressions involving the frequency. For a resistance of 15 kilohm and a capacity eiger value of 3 pF a circuit of about 7.5 kilohm is satisfactory.

Title: Piston ring sealing device with double ring - has ring joints staggered to reduce leakage loss
Inventor: MORIARTY MAURICE J
IPC: F16J9/16
Filed: 1974-02-20
Abstract: The piston ring consists of two separate rings. The main ring has an axial thickness at its inner edge fitting closely in the groove of the piston. A rebate on its lower surface provides space for a second ring with a small radial clearance of .001 to .002 inches between the edge of the rebate and the inner surface of the ring. Both rings are of elastic material so that they exert a pressure on the cylinder wall. Both the rings are arranged in the groove so that the gaps between the ends of each ring are not in line in order to reduce leakage loss to a minimum.
Patent DE-2412044-A1 (DE)
Title: Fabric-reinforced, rubber(y) conveyor belt - has adhesion-promoting interlayers between rubber matrix and reinforcement, that are free of vulcanising agent
Inventor: BRAEUTIGAM JUERGEN
IPC: B65G15/34
Filed: 1974-03-13
Abstract: A flexible rubber(-type), fabric-reinforced, conveyor belt features intermediate layers free of vulcanising agent, acting as adhesion adjuvant between the reinforcement and the adjacent rubber layers. These interlayer(s) may be composed of 2-chlorobutadiene-polymer opt. contg. filler. The interlayer being free from vulcanising agent will remain unaffected when the conveyor belt is vulcanised and so retain its adhesion-promoting effectiveness independently of the nature of the rubber matrix. This increases the range of materials from which the belt may be mfd.

Title: Self securing deep sea anchor - with cylindrical body and cutting edges to bore into seabed
Inventor: KNABE STEFAN ING GRAD
IPC: B63B21/26
Filed: 1974-12-27
Abstract: The deep sea anchor comprises a floating, cylindrical body (1) surrounding a tall cylindrical central body (2) which slides axially in the outer cylinder. Both parts are floating and can be flooded to sink the anchor to the seabed. The outer wall of the outer cylinder is concave (5) to support windings of the anchor chain (6) while the bottom of the inner cylinder has cutting edges (3). As the structure reaches the sea bed the cutting edges cut into the bed while any movement on the anchor chain rotates the structure and enables it to dig itself in by virtue of spiral cutting edges (9) under the outer cylinder.

Title: Travelling dolly for opening and reloading tyre moulds - with inter-locked clamp guides to facilitate automatic control
Inventor: LEGOSTAJEW WALERIJ LEONIDOWITS
IPC: B29D30/06
Filed: 1975-01-27
Abstract: Tyre vulcanisation system has a series of tyre moulds in a row which are automatically opened, unloaded, reloaded and closed by a travelling carriage fitted with claws for releasing and lifting the upper mould halves from bayonet fitting clamps and moving the mould tops aside to allow other claws to unload and reload the base moulds. The mechanical linkages are such that the mould covers are removed by solitary action of the first set of claws but that the refitting of the mould tops is aligned and operated in conjunction with the action of the second set of jaws after they have reloaded the mould with a prefabricated, uncured carcass. Both jaw systems progress together along the series of mould tools. Design minimises the number of independent controls involved in positioning the grabs laterally and vertically, simplifying automation of the equipment.
