Title: Novel rapid binder made from plastic
IPC: B42F13/14
Filed: 1982-03-06
Abstract: The invention relates to a filable, novel rapid binder according to Fig. 1, consisting of two binding strips which are connected to each other by a flexible spine and two rotatable spikes, each of which ends in a tab. The pre-perforated documents which are to be bound are received by the two profiled spikes which are rotatably mounted in the lower binder strip. The tabs of the two spikes are each rotatable through 135 DEG  in the plane of the binder strip, relative to each other, and can be locked in three specific positions as a result of interaction between the profile of the spike and a correspondingly shaped perforation in the binder strips. With tabs pivoted through 90 DEG relative to the spine of the binder, the binder can be filed as a whole; with 135 DEG  relative tab rotation it can be opened; with the tabs pivoted in, the binder forms a self-contained, easily mailable unit with an attractive visual appearance. <IMAGE>

Title: Windsurfing board, the special feature of which is a rig which can be reefed and trimmed
Inventor: WAVEREN BERNHARD LEENDERT ERLO
IPC: B63B35/79
Filed: 1982-04-08
Abstract: The present invention differs from the hitherto customary rig for windsurfers in three decisive points:   A) the mast, which is drop-shaped in cross-section, can be turned as desired about its longitudinal axis in relation to the angle of incidence of the apparent wind, so that B) the sail battens of the loosely guided sail can be tightened or relieved;   C) the sail can be reefed on the water. Sail positions and mast positions in optimum form are possible due to A) and B). Transversely set mast with bulbous sail, downwind. Inclusion of the lee side of the mast in the sail, sailing with flowing sheets. Likewise when luffing, or further turning and thus flatter sail and separation of flow from the mast to reduce the sail pressure. Generating an S-shaped wing profile by relieving the leech, for further pressure reduction during increasing wind. The reefing possibility is an additional safety feature, necessary in order to be able to reduce the sail area in the face of a suddenly increasing wind.
Patent DE-3214834-A1 (DE)
Title: Folding door
Inventor: REJC GABRIJEL
IPC: E06B3/48
Filed: 1982-04-21
Abstract: The folding door has at least one door leaf and a running-rail arrangement at the upper limitation of a door aperture. The door leaf consists of two segments which are connected to one another in an articulated manner and of which one is mounted directly in a door-leaf bearing and the other is guided, at the end of its upper edge facing away from the first segment, by the running-rail arrangement via a guide roller. The individual segments each consist of a segment filling and of a supporting structure which supports the weight of the segment filling on the bearings assigned to the segment. The supporting structure of the other segment consists of a pivoting arm which is arranged on the upper edge of the other segment and on which the segment filling of this segment is suspended, the pivoting arm being connected in an articulated manner at one end to the supporting structure of the other segment and also being supported vertically at its other end on the running-rail arrangement. The extension of the supporting structures into the region of the two mutually confronting edges of the two segments is thereby avoided, so that damage to the supporting structure by knocks against the segments is largely prevented.

Title: Method and system for measuring ion concentrations
Inventor: KLEIN MANFRED DIPL PHYS
IPC: G01N27/414
Filed: 1982-05-05
Abstract: The invention relates to a method and a system for measuring ion concentrations in solutions using ion-selective measuring and reference electrodes. According to the invention, at least two ion-selective measuring electrodes are used which have different sensitivities only for the ion or ion mixture to be measured but have the same sensitivity for the other ions. Taking the difference between the output signals of the measuring electrodes achieves the result that the measurement is essentially independent of the absolute value of the electrical potential of the reference electrode. <IMAGE>

Title: Attachment of the end of a length of beading to a profiled strip
Inventor: LANG FRITZ
IPC: B60R13/04
Filed: 1982-07-05
Abstract: A hidden attachment of the end of a length of beading to a profiled strip is proposed. The beading is connected to the profiled strip by a spring bracket being connected to the end cap, which spring bracket has a bent part which points towards the underneath of the end cap, is resiliently seated there and has at least one tip, it being possible to push the beading into the insertion opening between the underneath of the end cap and the part of the spring bracket. The spring bracket locks the beading against sliding back in the direction opposite to the insertion direction, and the clawing attachment of the beading to the profiled strip and to the end cap holds the beading firmly even when it contracts as a result of temperature reductions.

Title: Process for the isolation of crystalline 1,3-cyclohexanedione
Inventor: LITTERER HEINZ DR
IPC: C07C45/83
Filed: 1982-10-04
Abstract: The invention relates to a process for the isolation of crystalline 1,3-cyclohexanedione from the crude product formed in catalytic gas-phase cyclisation of 5-oxohexanoic acid. This is done by adding to the crude product, before or directly after condensation, an auxiliary component comprising at least one compound from the group comprising cyclic hydrocarbons, chlorinated aliphatic hydrocarbons and monoethers, then distilling the mixture comprising crude product and auxiliary component under atmospheric or reduced pressure until the water of reaction has been removed and the residual content of auxiliary component in the remaining concentrate has reached a certain value and filtering off the crystalline 1,3-cyclohexanedione precipitated after this treatment. It is also possible to distil off the auxiliary component added virtually completely from the 1,3-cyclohexanedione. In this case, one, either the same or a different, compound or compound mixture mentioned as auxiliary components must then be added again to the remaining concentrate which is interspersed with crystals, so that the 1,3-cyclohexanedione separates out as completely as possible as crystals and a crystalline paste which can be filtered is formed.

Title: Intermediate product for a compound profile intended especially for the production of window or door frames, process for its production, process for the production of a compound profile from the intermediate product and separating device for implementing the latter process
Inventor: NAHR HELMAR DR DR
IPC: E06B3/267
Filed: 1982-12-06
Abstract: The invention relates to compound profiles for window or door frames, consisting of two metal profile rails which are joined together by means of an insulating element. The profile rails are first of all joined together by means of at least one connecting web which is removed in order to produce the finished compound profile. To make it possible for the connecting web to be removed more simply, it is proposed that an air gap be provided between the insulating element and the connecting web and/or that the connecting web be provided, on its side remote from the insulating element, with a gripping rail 12 which is made in one piece with the connecting web and is angled in profile. Both the air gap and the gripping rail permit engagement by a separating tool, so that a substantially automated separation of the connecting strip from the profile rails is possible. Within the overall scope of the invention, a plurality of processes for separating the connecting strip, for introducing filler into the hollow space enclosed by the profile rails, and devices for implementing the process and separating tools are proposed.

Patent DE-3318828-A1 (DE)
Title: Method of bonding target material to cathode bases for use in cathode sputtering coating methods
Inventor: GLAESER HANS JOACHIM DR
IPC: H01J37/34
Filed: 1983-05-24
Abstract: A novel method is provided for bonding a target material to a rectangular, essentially flat cathode base surface for use in cathode sputtering coating methods. After first roughening the surface, an adhesion-promotion layer is applied to it, preferably by electroplating or flame spraying. The target material is then applied by a flame-spraying process. This structure is then thermally post-treated, in particular sintered, reduced and compacted, and then slowly cooled. The target material can be sprayed on in accordance with the erosion profile of the sputtering method. In this way, target coatings of low porosity and oxide content and very good adhesion can be achieved, thereby avoiding explosive spraying of target particles and local overheating during sputtering. Such coated cathode bases are suitable, in particular, for coating large-area glass panes with bismuth or a bismuth/manganese alloy. In such cases, nickel or a nickel/aluminium alloy is particularly suitable as an adhesion promoter. <IMAGE>

Abstract: In this pattern, a bar code differing from the other major axis is arranged for each of the two mutually perpendicular major axes X and Y in repetitive, mutually alternating bar-code fields having at least one bar code line perpendicular to its major axis in each case in a chequer-board or parquet-like pattern. The length of the bar code lines of the code for one major axis of the projection corresponds to the code field width of the code for the other major axis, the code fields being arranged at a constant distance from one another and in each case consisting of three code lines. To identify the direction of movement, the bar codes are designed to be unsymmetric and are arranged at a constant distance from one another which, like the distance of the bar code lines from one another, is four times as large as the extent of the resolution of the optical sensor. The codes or bar code lines consist of three bar code lines having two different line widths and spacings, the width of the narrow lines corresponding to half the extent of the resolution of the optical sensor whilst the wide bar code lines and smaller spacings between the bar code lines are exactly as wide, and the larger spacings between the bar code lines are twice as large as the extent of the resolution of the ...
