Title: Collapsible pram/pushchair frame
Inventor: WEGNER ALBERT
IPC: B62B7/08

Abstract: The invention relates to a collapsible pram/pushchair frame with two parallel, lateral front struts on which two rear struts are coupled, via tilting hinges, in a manner which allows then to pivot in the direction of the front struts, which front struts and rear struts have on their lower end portions front wheels and rear wheels and are conencted to one another via a scissor frame arranged between the lateral pairs of struts, the ends of the scissor-type struts being coupled in a rotationally articulated manner both to the front struts and to the rear struts and in each case one front strut being connected to the rear strut located therebehind via hinged seat pillars of an integrated child seat, the front struts rising obliquely rearwards in the opened out in-use position of the pram/pushchair and the rear struts running essentially vertically. In a pram/pushchair frame of this type provision is made for bearing holders to be fastened in a longitudinally displaceable manner to the two rear struts, to which bearing holders the rear ends of the two scissor-type struts are fastened in a rotationally articulated manner and the seat pillars are fastened pivotably, and on displacement of the bearing holders into a lower sliding position for the pram/pushchair frame to be opened out and for it to be folded up by displacement of said bearing holders into an upper sliding position.

Title: Process for the preparation of mixtures of used plastic containing halogen components for use in refinery plants
Inventor: GEBAUER MANFRED DR
IPC: C10B7/10
Filed: 1993-09-01
Abstract: The residual chlorine contents in thermally degraded mixtures of used plastic containing a halogen component were to be reduced as much as possible. The mixtures of used plastic are comminuted, freed from entrained impurities and pre-degraded at elevated temperature and under shear forces in an extruder, where, at the end of the extrusion process, alkali or alkaline earth metal compounds are added to the mixtures of used plastic after removal of the thermolysis gases, and the resultant mixture is homogenized in a connected static mixer. The chemical binding of the residual halogen after thermal dehalogenation enables the mixtures of used plastic from domestic plastic garbage to be processed without difficulty in refinery plants.

Patent DE-4342106-A1 (DE)
Title: Shaped=strip bearing rail for crane tracks etc.
IPC: B66C7/02
Filed: 1993-12-11
Abstract: The bearing rail has webs (29) consisting of folds in the sheet. The open side of the fold can be welded for greater stability. To produce the fold, the sheet for the flanges is cut at a right angle before making the 180 deg. C fold at flange width. The opposite flange is produced similarly. The running surface sections (27) have the running surfaces (33) produced by 180 deg. C inward folds in the sheet. There is no need for further welding here. All the folds can be made in the sheet before the final bending of the sheet in U-form to bring the two flanges parallel to each other. The rail can be made from one sheet or from a number of shaped rods. The baseplate (26) may be produced from a channel bar.

Title: Magnetron sputtering unit giving improved removal of target material
Inventor: LINNENBRUEGGER ANDRE DIPL ING
IPC: H01J37/34
Filed: 1993-12-15
Abstract: The magnetron sputtering unit incorporates a tubular target, a system of magnets with alternatingly different pole directions arranged axially one after another, and means for producing axial motion of the fields produced by these magnets. The magnets are formed by means of current-carrying coils (17-22). The current direction through each group formed by at least two adjacent coils is chosen so that they produce magnetic fields of the same sense. Axial motion of the magnetic fields is produced by means which periodically alter the direction of the current through the coils located at the group boundaries.

IPC: H02J7/00
Filed: 1994-06-29
Abstract: The invention relates to a process and device for charge exchange between a plurality of series-connected identical energy stores (1) in which at least one electric store (3) is alternately connected in parallel to the energy stores (1) at a given rate. Here each electric store (3) is formed from a transformer component (3) charged by the energy stores (1). The transformer components (3) are connected at said rate in parallel to one of the identical energy stores (1) with alternating polarity so that all the identical energy stores (1) are individually connected in parallel at each step to a transformer component (3), thus facilitating a direct flow of power from one or the high-grade store(s) (1) to a low-charged store (3). The process and device may be used to balance the charge of energy stores (1) like accumulators and for energy converters, e.g. in the form of fuel cells.

Title: Remote control transmitter
Inventor: ANEHA AKIRA
IPC: H04B1/034
Filed: 1994-07-25
Abstract: A remote control transmitter is capable of preventing a student remote control transmitter from outputting a radio wave even if the student operator accidentally has closed a power switch on the student remote control transmitter. The transmitter comprises a radio frequency circuit for modulating a control lever operating signal which is decoded by a coder, and for outputting in the form of a radio wave, and a power control section for discriminating which is conducting a current through from an internal power supply and an external power supply, and for latching a result of the discrimination. The power control section also controls switches for feeding the coder and the radio frequency circuit with a current in dependence on the result of the discrimination. A learning switch is provided which can be applied selectively with a signal to the radio frequency circuit from the coder or a learning cable. The power control section is fed with a current through the learning cable from the external power supply or through a diode from the internal power supply.

Title: Stiffening element for construction and security elements
Inventor: VES KLAUS DIPL ING
IPC: E04C2/36
Filed: 1994-08-06
Abstract: The stiffening element has stiffening webs (01) running vertically towards each other. The difference in length caused by warping, corresponding to the difference between the internal and external warp radii, is taken up in the transverse webs by their turning. The honeycomb structure, as specified e.g. as in DIN 29 970, is pushed together in such a manner that the angled web parts, originally at 135 deg., now form an angle of 90 deg. There may be webs running through the element crosswise to the bending or warping direction, linked by bands meandering at right angles.

Title: Magnetooptical storage element
Inventor: MIEDA MICHINOBU
IPC: G11B11/105
Filed: 1994-08-25
Abstract: A magnetooptical storage element has the following: a transparent substrate (1); trenches which are formed on at least one surface of the transparent substrate in order to guide a light beam; raised regions which are respectively formed between the trenches; a magnetooptical recording layer (3) which is formed on that surface of the transparent substrate on which the trenches are located; and tracks formed in the trench regions and raised regions for recording and reproducing information; the width of each trench and of each raised region being substantially the same; the trench depth d being chosen such that the following condition is satisfied: 0.13 x  lambda /n </= d </= 0.18 x  lambda /n,  lambda  being the wavelength of the light beam and n being the refractive index of the transparent substrate. The track spacing is preferably chosen such that: 0.6 </= L/p </= 1.2, L being the diameter of a region of the light beam at whose edge the light intensity is 1/e<2> of the light intensity in the centre of the beam. Therefore, satisfactory signal quality with a low level of crosstalk is accomplished even if the track density is increased, i.e. if the width of the trench region and of the raised region is reduced. Accordingly, a high recording density can be accomplished with such a magnetooptical storage element. <IMAGE>
