Patent DE-2446700-A1 (DE)
Title: Is-oxazoles and polymers fluorescing on exposure - used in dry data storage process, for speed, accuracy and no fixing
Inventor: BAUMANN NIKLAUS DR
IPC: C09K11/06
Filed: 1974-09-30
Abstract: Isoxazoles (Ieand polymers with recurring units (II): (in which R and R1 are residues of mono- or poly-nuclear aromatic or heterocyclic cpds.; A is an opt. substd. isoxazole gp.; n = 1 or 2) are, in part, novel cpds. They are used as precursors (for oxazoles), which are non-fluorescent aand become fluorescent on exposure or are fluorescent and undergo a shift of the fluorescence max. towards longer wavelengths on exposure, in a data storage process. The fluorescent cpds. formed have high light-fastness, optimum fluorescence quantum yield and very short decay period of the first singlet stage. Detectable fluorescence can be produced in nano- to milli-seconds. The process is dry, rapid and accurate. The data can be made visible repeatedly. No fixing is necessary, since the isoxazoles are not sensitive to the long wave radiation used for making the stored data visible.

Title: Yarn cross winding machine yarn inserter - formed by axially slidable arm carrying a number of yarn guides and pivotable into contact with bobbins
Inventor: BURKHARDT KLAUS
IPC: B65H65/00
Filed: 1975-06-14

Title: Sports shoe grip element - has spiked plate fixed to screw piece, and is used on plastics running tracks
Inventor: KAESTLE BERTHOLD
IPC: A43C15/16
Filed: 1975-09-11
Abstract: The running shoe spike consists of a screw piece (1) to which is fitted a domed plate (1). A number of gripping teeth (3) are cut into the plate (2) to fit the plate (2) to the screw piece (1) a hole (4) is cut in the centre of the plate (2). A spike is fitted into the central hole (4).

Title: Coated optical fibre preform prodn. - by depositing coating from soln. and moderate heating, is fast, simple and cheap
Inventor: DAKIN JOHN PHILIP DR
IPC: C03B37/016
Filed: 1975-10-09
Abstract: Prodn. of a coated optical fibre preform involves depositing coating material (I) from soln. on the surface of a substrate (II) by first wetting (II) with a (I) soln. and providing a completely uniform coating where required and then heating moderately after evapn. of the solvent. The process is faster, simpler and cheaper for commercial operation, than chemical vapour deposition. In an example, the inside of a doped quartz glass tube was coated with a soln. of Si(OEt)4 in alcohol mixed with HNO3, dried and heated 5 min. at 100 degrees C. Heating above 1600 degrees C and drawing gave an optical fibre in which the core was formed from the coating.

Title: Combustion system for engine - using swirl recess in piston to produce flow into precombustion chamber (BR010277)
Inventor: LATSCH REINHARD DIPL ING DR
IPC: F02B1/04
Filed: 1976-04-10
Abstract: The internal combustion engine has a cylinder block (1) with a piston (2) and cylinder head (3) with a depression (4) forming part of the combustion chamber. A mixture of fuel and air flows through the inlet port (5) and valve (6) and enters the combustion chamber in a tangential direction which produces a swirling motion. This swirling motion produces a relatively richer mixture at the periphery of the combustion chamber which then flows into the ignition chamber (8) where is is readily ignited by the plub (11). The ratio of the volume of the compression chamber (4) to the volume of the ignition chamber is preferably about 10:1. The separate ignition chamber results in smoother running on weak mixture.

Filed: 1976-05-05
Abstract: A greenhouse has a sloping roof with a large number of panes of glass, some of which carry reflective sheets and others which have reflective sheets over half their area so that the brightness and heating effect inside is reduced. The half sheets may be controlled by a drive so that they can be moved to cover the remainder of the uncovered area of the panes. They may be aluminium strips attached to the inside of the panes or may be movable sheets mounted underneath, to travel on runners. In another form, the panels may increase the heat of the sun passing through. In the first form, they may also act as heat insulation. The fixed sheets may occupy about half of the total glazed area.

Title: Treatment of infectious rubbish esp. from hospitals - applies disinfection by use of hot air, steam IR or eddy current heating
Inventor: ANNA OTTO PROF DR
IPC: B65F7/00
Filed: 1976-05-15
Abstract: Rubbish and waste products from medical institutions is liable to contain infectious media which need to be neutralised by sterilisation so that the rubbish can be handled as normal domestic waste. The necessary disinfection is achieved continuously or discontinuously using a hot air chamber which is cylindrical in shape and is rotated while in an inclined position. A crushing or similar fragmentation process facilitates the passage of the disinfection medium. A metal heating unit employs IR radiation, or eddy current heating is employed. A press is placed at the outlet in order to reduce the volume of the emerging disinfected waste.
