Title: Brushes for holding disc shaped workpieces upright on conveyor - preventing workpieces from falling down when one is removed from row
Inventor: HEIGL HANS
IPC: B65G11/20
Filed: 1975-07-23
Abstract: Device for holding disc-shaped workpieces e.g. gears on or in a conveyor channel e.g. during transport from one machine tool to another comprises flexible rods which are arranged in continuous or discontinuous rows parallel to the direction of transport, which extend perpendicularly to the direction of transport, and which at least contact the workpieces. Pref. there are two or more rows of flexible rods defining between them a gap smaller than that taken up by the workpieces, and the rods are in the form of rows of bristles or bristle strips made of plastic e.g. nylon or spring metal. The bristles also have the effect of removing shavings from the workpieces. In the cases of helical gears, these rotate during axial displacement so that all the teeth come into contact with the brushes.

Title: Chamber furnace for ceramic products - with moving flame and stationary charge giving increased heat transfer output
Inventor: HAESSLER ANDREAS
IPC: F27B13/02
Filed: 1975-06-18
Abstract: The chamber kiln for firing ceramic products is operated with a moving flame and stationary charge, with a flue gas conveying device which is reversible within secs. and which is disposed between the waste gas stack and flue gas collecting channel. The connection between at least the last chamber filled with blanks and the succeeding chambers is sealed off with draught- and pressure-tight blocking means, and for a short-period flue gases are alternately drawn from the kiln and injected into it. The blocking means between the individual chambers may be removable with advance of the flame, or destructible from the outside or automatically by thermal action with advance of the flame, or they may be in the form of inflatable air cushions. In case of direct firing, the fuel may be introduced into the chambers in synchronisation with movement of gas.

Title: Metal coated plastic foils - joined to terminals with projections heated and pierced through coating and foil
Inventor: PRZYBYLSKI ZDZISLAW DR
IPC: H01G4/228
Filed: 1975-09-30
Abstract: Terminals are fixed to metal-coated foils made of a thermoplastic material as used for the plates of small capacitors by providing each terminal at one side with several projections which are heated above the m.pt. of the plastic. When applied to the foil between an anvil and a plunger, the projections pierce through the metal coating into the plastic. The pressure is maintained until the molten thermplastic has re-solidified. A joint thus produced has good mechanical and electrical properties. The joints are reproducible in a uniform quality in long production runs.

Title: Ink markings on ink-repellent plastic surfaces - with application in one stage without reduction in speed
Inventor: FISCHER BERND ING GRAD
IPC: H01B13/34
Filed: 1975-10-15
Abstract: Ink markings are produced on plastic bodies with smooth ink-repellent surfaces, partic. insulation for electrical cables or conductors with an extruded layer of plastic based on fluorocarbon resins, using a powdered ink sprayer mounted in the immediate vicinity of the extruder nozzle. In an example, a cable with an insulating coating of ethylene-tetrafluoroethylene is unwound from a drum and passed through an extruder immediately behind the nozzle of which is mounted a sprayer to which compressed air acting as an ink carrier is supplied perpendicularly from above. The horizontal spray nozzle is directed towards the cable and sprays the still warm insulating coating with a mineral powdered ink.

Title: Double piston two stroke IC engine - in which exhaust gas in expelled by counter working piston
Inventor: ABOU-KAMAL SAMY DIPL ING
IPC: F02B75/28
Filed: 1975-10-22
Abstract: Engine consists of a main piston (3) reciprocating in a cylinder and connected to the crank shaft in the usual manner. A regulator piston (2) acting as a displaceable cylinder he head is actuated by a lower (8) and an upper rocker arm joined by a push rod (10). The lower rocker arm is actuated by a cam (6) fixed to the crankshaft. The cam profile causes the regulator piston to move faster then the main piston. A rotary valve (4) regulates an opening on the cylinder wall for gas exchange purposes. The engine works on the two stroke principal where by the main piston moves below the intake rotary valve to admit an air feed mixture while the regulator piston moves to the top of the cylinder. The main piston then compresses the mixture whilst the regulator piston stays at the top of the cylinder. Ignition occurs and the main piston moves down on power stroke. The rotary valve opens just before the end of the power stroke and the regulator piston moves down to expel the exhaust gases and return.

Title: Skip handling and dumping equipment - has shaft below spreader coupled to tilting beams supporting skip
Inventor: ZIMMER ALBERT
IPC: B66C1/66
Filed: 1975-11-12
Abstract: The equipment is for the handling and dumping of large skips equipped with supporting trunnions, and comprises a lifting spreader spanning the skip and supports engaging with the trunnions on both sides of it. A hand- or motor driven shaft is mounted below the spreader, its ends being coupled either direct or via chains to tilting seesaw-type beams. These support the skip in such a manner as to allow dumping of the contents from it. The skip supports can be linked to the free ends of the beams at points the same distance apart as the skip trunnions. Thus a parallelogram linkage is formed, tipping the skip about its centre of gravity.

A fluid pressure drop below a given value opens the valve for free-flow discharge with underpressure. A filling pressure rise closes the valve without fluid egress. A gallery ring holds a flexible sealing disc across an air nozzle pipe connected in the tank's upper region. An adjacent axial housing connected with the tank's contents contains a fluid pressurised diaphragm, a flexible backing washer and a clearanced guideplate. The disc and diaphragm move simultaneously being held on spacer flanges.

Title: Contact system for circuit breakers - has moving contact with switching force boosted by directly associated ferromagnetic member
Inventor: BRUCKNER WERNER
IPC: H01H1/54
Filed: 1976-04-10
Abstract: The contact system is intended for isolator, load and/or fault current circuit breakers with at least one stationary and one moving contact. In the system the contact force is boosted by a ferromagnetic part (68, 69) which is associated to the contact system in case of current surges. If a current flows in opposite direction in each contact the ferromagnetic part is preferably arranged between the parallel mounted contacts. If the current flows through the contacts in the same direction, at least one contact carries the ferromagnetic part on the side away from the contacting surfaces. The ferromagnetic part may be soft magnetic material and may have any arbitrary cross section.

The sulphate employed is pref. in the stoichiometric ratio to the Ca++ ions present, and is obtd. from conc. or dil. H2SO4, or solid metal sulphates or solns. of the latter. If the initial acid soln. contains sesquioxides or silica, the soln. is pref. heated and a neutralising agent added, e.g. MgO, to ppte. these cpds.; the soln. is then cooled and the sulphate ions added; the pptes. can be removed separately or together from the soln. Used for the purificn. of MgCl2 solns., which are then thermally decomposed to obtain MgO and gas from which HCl can be mfd. The process may also be applied to other chloride solns.,.

Title: Recovering halogen from soln. - by adsorption onto hydrophobic nonionic polymer with exclusion of light
Inventor: LEWIN MENACHEM
IPC: C01B7/01
Filed: 1976-09-20
Abstract: Halogen-contg. plastics materials are made by contacting hydrophobic polymers contg. no ionic or ionisable gps. and which are free from ion exchange activity, with a soln. of a halogen with the exclusion of light. Suitable polymers include polyolefins (polyethylene, polypropylene, polyisobutylene etc.), polystyrene, polyacrylonitrile, polyacrylates, polymethacrylates, PVC, PTFE and other polyesters, polyamides, polyacetals, etc., in the form of powders, granules, foams, fibres, films, fabrics, gels, etc. Plastics scrap is an esp. economical material. The plastic is pref. contacted with a soln. of the halogen, esp. at a pH of 0-3. Lower pH's give gaster rates of halogen extn. The halogen is adsorbed reversibly from the soln. to give a stable material which can be transported and used later as a halogen source. Process can be used e.g. for recovering Br2 from salt solns. such as sea water, e.g. after oxidn. of bromide present in the soln. to Br2 e.g. using Cl2 gas.
