Title: Composite plastic articles, esp. epoxy or polyester - with reduced tendency for reactants to separate
Inventor: EYERER PETER DIPL ING DR ING
IPC: C08G59/40
Filed: 1973-12-19
Abstract: In a method for prodn. of a plastic article by chemical reaction, opt. while supplying energy, in which a starting material, a reactive substance and an additive are mixed together, >=1 of the latter two having a specific wt. different from that of the starting material and having a tendency to separate out from the reaction mixt. reducing viscosity, the additive is so chosen that it serves as a carrier for the reactive substance, and is mixed with the starting material in the form of a composite with the reactive material, and the buoyancy of this composite in the starting material is approx. equal to its wt. Both the reactive substance and the additive remain suspended in the starting material and sepn. of reactants is avoided. The composite can be formed by enveloping solid particles of the additive with reactive substance, eg. above the m.pt. of the latter followed by cooling. Alternatively when the additive is a porous material, it solid particles can absorb liq. reactive substance. Liq. additive can also be intimately mixed with the reactive substances to form a stable suspension or emulsion. Starting materials in this method may be epoxy resins or polyesters; reactive substances include stabilisers, inhibitors, catalysts, hardeners, etc., additives include fillers or solvents.

Title: Open-end spinning rotor bearing - has flexible O-rings to give a floating bearing to resist external forces
Inventor: WEHDE HEINZ DR RER NAT
IPC: D01H4/14
Filed: 1974-01-30
Abstract: The design of the bearing for a high-speed rotor, such as in an open-end spinning unit, uses flexible 0-rings in conjunction with the bearing bush to hold the rotor to the stator to contain the centre of gravity within the floating bearing. The design prevents operating forces affecting the bearing, preventing wear which would lead to imbalance in running, and to increase bearing life.
Patent DE-2405852-A1 (DE)
Title: Low noise hydraulic control valve - has wire mesh coil to produce progressive pressure reduction
IPC: B66B1/04
Filed: 1974-02-07
Abstract: A valve, used to control hydraulic lifts is required to operate at a low noise level. The valve piston carries a wire mesh coil which extends into the outlet port. A sleeve with open axial slots encloses the wire mesh and also extends into the outlet past the valve seat. With the valve shut, the O-ring at the piston face seals the valve. When the piston is retracted, the fluid is able to flow from a ring chamber through the slotted sleeve and the coiled wire mesh to the outlet. This produces a progressive pressure drop which prevents noise formation.

Title: Analyser with automatic mechanism in body - moves several test tube systems in rack simultaneously to measuring point
Inventor: SUOVANIEMI OSMO ANTERO
IPC: G01N35/04
Filed: 1974-02-22
Abstract: The automatic mechanism consecutively measures automatically at certain time intervals all the test tube systems in the test tube system rack. The specimens are automatically displaced simultaneously from the tube in the test tube system into other tubes corresponding to those in the system by means of controlled pressure. After measurement the specimens are moved back out of the other tubes by operation of a suction action into the tubes of the test tube system. Before the following measuring operation the other tubes are rinsed once or several times either with water or with an appropriate reaction solution.

Therefore, the liq. can be used in field conditions. The pref. substance capable of liberating an oxidising agent in H2O2. It can be combined with hydroquinone or Pb2/Fe(CN)6/ as binding agents. The soln. is pref. stabilised with respect to H2O2. It can be buffered to keep the pH constant.
Patent DE-2414929-A1 (DE)
Title: Vibration damper and shock absorber - consists of two discs surrounded by sleeve in which a flowing medium is contained
Inventor: LOCHNER KASPAR
IPC: F16F9/30
Filed: 1974-03-28
Abstract: The damper consists of two solid or cup shaped elastomer discs which are bonded to solid discs. A flexible sleeve is bonded round the two elastomer sleeves. A flowing medium is contained in the space between discs and sleeve, the viscosity of which remains approximately constant with temperature. When the end discs are moved together, the medium squeezes out from between them and the sleeve expands. Various shapes can be given to the discs, so that part of the medium becomes trapped when the disc moves together and narrow gaps form choke paths to the flowing medium. Alternatively, a sleeve with small holes can be mounted round the discs inside the flexible sleeve.
Patent DE-2418707-A1 (DE)
Title: Safety gas lighter device - has gravity operated contact to short voltage generator while lighter is inverted
Inventor: MORIYA NOBUYOSHI
IPC: F23Q2/28
Filed: 1974-04-18
Abstract: When inverted the movable contact means (24) will vertically slide down as guided by the pin (25) within the guiding slot (23) of the guide plate (22) and will come into contact with the metal plate (17). Upon such contact, the movable contact means (24) operate to connect the plate (17) and high voltage electrode nozzle (15) to the low voltage side of the high voltage generating device (3) thus effectively paralleling and shorting out the spark gap. Therefore, even if the thumb piece (11) is inadvertently pushed by the user, for example, during the course of fuel refilling actuation and while the lighter is inverted, spark discharge in the vicinity of the gas delivery nozzle (15) is precluded because of the short circuit.

Title: Spring hanger device for matt frames - holds flat spring end inside tubular mattress frame with flap forming rest beneath spring
IPC: A47C31/06
Filed: 1975-06-06
Abstract: The device for hanging flat springs on a tubular metal mattress frame has a pair of notches (13, 14) in the tube at distance (a) apart which is greater than the distance (b) between the first notch (13) and the end of the springs (18). Each notch produces a flap (16, 17) which is bent back into the tube. Next to the flat (16) of the first notch (13) is a groove like depression (20) corresponding with the shape and diameter of the spring so that the spring can be easily inserted into the tube (10). The first flat (16) is bent bact to form a rest beneath the spring. The second flap (17) is bent over the top of the spring (18) so that the spring cannot tip. This device provides a safe hanger for the spring with a smooth finish which cannot damage the cover or mattress.

Title: Orbiting masses for vehicle drive - are rotated eccentrically about radial axes to produce resultant driving force
Inventor: GROSSMANN FRANZ-KARL DIPL ING
IPC: F03H99/00
Filed: 1975-08-16
Abstract: The centrifugal drive for vehicles comprises a rotatable carrier (4) for a number of masses (21) secured eccentrically to respective radial shafts (5) arranged on the carrier. The shafts are connected by bevel planets (11) to a stationary sun gear (18) so that on rotation of the carrier the masses orbit about the axis of the carrier and rotate about the radial axes of the shafts. The movement of the centroid (S) of each mass about its radial axis is alternately added and subtracted from the movement about the carrier axis. This provides a resultant force capable of driving the vehicle.

Title: Flat item stacking machine - has vacuum chamber with perforated wall past which items are transported
Inventor: LOOCKWOOD ARTHUR WILLIAM
IPC: B65H29/32
Filed: 1975-10-04
Abstract: The equipment delivers the items to the desired position, having a chamber (1) with one or more walls (2) in which there are a large number of small apertures. A vacuum is generated in this chamber so as to hold the items up as they are transported, typically by an endless gas-permeable conveyor belt (3). The belt can be of non-electrostatic material, running over the wall with the apertures in it, and held taut as it does so. The vacuum can be created by an exhauster inside the chamber, and the rate of air or gas inflow into the chamber can be adjustable.

The screens obtd. from the matrix can be used in printing works or for mfg. printed circuit boards or heater foils. The working life of the matrix is twice that of a conventional matrix and the accuracy of the screens obtd. is not impaired during the increased life.
