Title: Blow moulded container pre-form with vari - able wall thickness
Inventor: HANSEN DIPL-KFM LOTHAR
IPC: B29C45/26
Filed: 1968-12-20
Abstract: Method is used in order to achieve uniform wall thickness in a finished blow moulded vessel with rotational axis of symmetry and varying diametral form. The variable thickness preform is injection moulded in a plain cylindrical mould with a contoured core piece. This enables the mould cavity to be a single piece rather than two piece, and enables the wall thickness of the resulting pre-form to be varied easily by modification of the core piece.

Title: Heat treating moving band - with adjustment of air nozzles to different
IPC: F26B13/10
Filed: 1970-06-15
Abstract: A device for heat treating a continuously moving band of material or goods by means of air, where the air is supplied through nozzles pointing transversely to the band surface and also by a transverse air stream sweeping across the band and around the nozzles, is adjusted to various widths of band by obstructing or covering the non-utilised nozzles only on the side of the band away from the inlet of the transverse air flow. This arrangement ensures that the adjustments required for obstructing the nozzles are effected only on the accessible side, not on the side where the air inlet ducts are mounted. The associated loss of efficiency by having non-utilised nozzles on the air inlet side is small.

Title: Fur comber - for long-haired furs with vacuum withdrawal
IPC: C14B1/00
Filed: 1970-10-28
Abstract: The material is carried on a permeable conveyor for presentation to the combing cylinder, and as the conveyor turns down and back on its end roller, a vacuum zone grips the material and withdraws it from the combing cylinder. At the end of the vacuum zone the material is released, and pulled by gravity to a further conveyor for return to the operator. The purpose is to prevent the operator withdrawing the fur from the combing cylinder by hand, and to prevent the materials being carried round by the combing cylinder.
Patent DE-2110650-A1 (DE)
Title: Use of atomic reactor heat - in chemical reactions by preheating reaction/combustion components with reactor coolant
Inventor: VOLLHARDT FROHMUT
IPC: G21D9/00
Filed: 1971-03-05
Abstract: Heat from an atomic reactor and from combustion of a fuel is used for carrying out chemical reactions by transferring heat from the reactor to the air and/or the fuel before combustion, as in DT 2042432. In chemical reactions where the heat requirement is convered by combustion of oil, gas or other fuels, the components concerned in the chemical reaction are pre-heated by the coolant in an atomic reactor - alone or with the fuel and air combustion components - , whilst the reaction or combustion components are further preheated by the combustion gas. In this way, the use of heat from an atomic reactor is extended to other chemical reactions besides combustion, e.g. prodn. of cracked or synthesis gas. The danger of explosion when water, steam and aq. soln. is used in heat exchanger operating with Na coolant from atomic reator is eliminated.

Title: Air-conditioning system with motor driven fan - uses day and night multiple switches to set fan motors supply current for volume adjustment
Inventor: SIEMENS FRANZ
IPC: H02P25/04

Title: I.C. engine injection system - opening period of injectors is controlled by manifold depression except at idle conditions
Inventor: HARTMANN GERHARD
IPC: F02D41/08
Filed: 1973-09-07
Abstract: Four cylinder engine has four fuel injectors one for each cylinder. The opening period of each fuel injector is controlled through a multivibrator circuit which produce via an amplifier fast opening and shutting of each injector and controlled length of opening. The multivibrator circuit includes a transformer whose core is connected by a rod to a diaphragm in a device which measures the depression in the inlet manifold of the engine and moves the core to affect the inductance of the transformer and thus influence the output of the multivibrator circuit. The period of the multivibrator is synchronised with the engine speed via a cam and a switch driven from the engine crankshaft. A further switch operated from the accelerator pedal changes the operating conditions of the engine only at idle.

Title: Improved aerodynamic wind screen wiper blade - having wind deflecting edge positioned next to blade to press on windscreen
Inventor: ASTHEIMER KARL
IPC: B60S1/38
Filed: 1973-09-13
Abstract: The windscreen wiper blade has a wind deflecting blade positioned next to it on the wind pressure side to deflect the slipstream over the blade holder and to improve the pressure of the blade onto the windscreen. The blade can be formed in one moulding with the deflector so that it is held in the same support. Alternatively the flexible deflector can be secured to the wind side of the blade support. It can touch the windscreen, or if made of thin metal and riveted to the holder, it is held at a short spacing from the windscreen, with the deflector angled to achieve optimum deflection. The position of the deflector next to the wiper, rather than on top of the wiper, provides optimum mechanical support.

A sleeve is inserted in the hole to act as a guide for the stopper during insertion and removal, and in the process protects it from damage caused by burrs on the underside of the hole. The sleeve can extend through the hole past any burrs formed. Sleeve length is such that the free end protrudes past the pipe wall inner burrs which facilitates easy fitting and withdrawal of the unit.

Title: Heat treatment furnace with tubular heaters - has perforated tubular gas ducts for enclosing radiant heaters
Inventor: COCHIUS RICHARD
IPC: F27B9/06
Filed: 1974-04-30
Abstract: The heat treatment furnace is heated by radiant heat generating tubes and is used especially for heat treatment temperatures below seven hundred degrees. This arrangement ensures a uniform furnace atmosphere also in the lower temperature ranges. The radiant heating pipes are enclosed into enveloping pipes so that an annular space is formed between each heating and enveloping tube. The gas forms the furnace atmosphere and is heated on passing through the annular gap. The enveloping pipe has perforations for supplying heated gas into the furnace chamber. The enveloping pipe end in the furnace is closed and the other end is open as the gas inlet. The gas outlet openings are suitably profiled and orientated in the required gas circulation directions. These openings can direct heated gas directly on the heat treated material.
