Title: Oxygen detector for internal combustion engine exhaust gas - having unstressed sealed mounting for electrolyte tube in housing
Inventor: POLLNER RUDOLF
IPC: G01N27/407
Filed: 1973-08-29
Abstract: An electrochemical detector for the oxygen content of gases, esp. exhaust gases of I.C. engines, comprises a solid electrolyte tube with electrode coatings on its inner and outer surfaces. The outer coating is in contact with the surrounding housing wall, fitting into a shouldered passage passing through the wall. The seal between the solid electrolyte tube and housing comprises a relatively thin sleeve of the housing forming an annular space around the electrolyte tube, this space contg. a seal at the bottom, with a fill of smelted glass above the seal, and a compression ring at the top. Pref. the seal has an edge ring of titanium, "vacon 70", or ceramic during installation, the seal prevents molten glass entering the space between tube and housing. The compression ring prevents the shrinkage of the wall when cooling from crushing electrolyte tube. Therefore the housing can be made of inexpensive material having a coeff. of thermal expansion which is considerably higher than that of the solid electrolyte tube.

Title: Rapid-setting aminoplast-formaldehyde resin foams - made from mixts contg resin, emulsifier, blowing agent and little water, by adding acids
Inventor: BLAKE ALAN DENIS
IPC: C08J9/04
Filed: 1974-01-18
Abstract: A resin, pref. urea-formaldehyde, with high viscosity and low solvent content, which either has a high pH or contains added alkali, is mixed with an emulsifier and a blowing agent and emulsified. An acid catalyst, opt. mixed with a blowing agent inert to acid, is then added, causing further reaction of the resin and the formaldehyde and an increase in temp. which causes blowing the occur. The resin, emulsifier and blowing agent are pref. emulsified for a long period before adding alkali, to cause some pre-polymsn without blowing, resulting in a less brittle foam. Setting of the foam occurs very quickly e.g in around 2s. The foams of carrying density can be used as impact-absorbing cushions, non-flammable building boards, fire-retardant separating walls, pipe insulation and for spraying on water surfaces as a barrier to contain oil pollution.
Patent DE-2404811-A1 (DE)
Title: Safety coat stand for schools - has coat hook members mounted to yield on impact
Inventor: HANSEN HANS-LORENZ
IPC: A47G25/06
Filed: 1974-02-01

Title: Drive motor in series with stepped resistance - has differential element connected to adjusting means via cct. with threshold response
Inventor: BERTLING ANTON DIPL PHYS DR IN
IPC: B60L7/04
Filed: 1974-08-05
Abstract: The arrangement is for a drive motor connected in series with a step-wise variable running or braking resistance and in which a motor winding with zero diode is fed from a separate source via adjusting means, whilst means are provided to receive a signal from a current transformer which signal is determined by the variation with time of the armature current occurring when the run or brake resistance is varied. The output of the differential element is connected with the control of the adjusting means via an electronic circuit which only responds when its input signal reaches a pre-determined value and supplies a signal of given duration to the control independent of the variation with time of the input signal.

Title: Cold sterilisation of bottles by sulphurous acids or sulphur dioxide - comprising enclosed vessel disinfecting and rinsing to prevent atmospheric pollution
Inventor: SILBERZAHN HELMUT
IPC: A61L2/18
Filed: 1974-10-25
Abstract: A device for cold sterilising bottles with sulphurous acids and/or sulphur dioxide, using a dipping wheel, on the circumference of which a closed mantle supports separate cells into each of which a bottle can be inserted and from which, due to their inclination the bottles fall out automatically at about the height of the wheel's axis, as the dipping wheel rotates stepwise, has a housing which is pressure tight except at the service opening. The complete drive transmission, moving the wheel in steps corresponding to the pitch of the bottle cells, and the freshwater spray zone for rinsing the bottles inside and out, are sepd. from the sterilising fluid. At the highest point in the housing there is a suction connection for the gas with a fan, in front of which a syphon creates a mist of freshwater. This dissolves the oncoming gas and returns it to the bath. Supersedes the labour intensive and time wasting dipping trollies as well as stem or hot water sterilisation of the bottle necks.

Title: Hydro dynamic brakes for motor vehicles - has plugs or vanes to impede flow operated by piston and cylinder connected to reservoir
Inventor: MERKLE HANS DIPL ING
IPC: F16D57/04
Filed: 1975-03-01
Abstract: The outer zone of the staor has devices for impeding fluid flow such as bolts or vanes and these are held by springs. Operation is by a cylinder/piston arrangement dependent upon the operating pressure from the working chamber. The bolts lie in an extension to the cylinder/piston and project directly into the separating slot (17) between stator and rotor. The piston acts on one side against the spring and is acted on by the pressure from the reservoir. There are radial boreholes (18) through which bolts (19) to project. Where blades are vanes are used they are adapted to the shape of the stator and similarly the facing surface of the bolts or plugs is adapted to the outer contour of the working chamber (12).
