Title: Sepg. and sorting plastic scrap and process equipment
Inventor: LADEMANN JUERGEN DR SC NAT
IPC: B07C5/34
Filed: 1993-01-25
Abstract: In a process for separating and sorting plastic scrap the plastic objects (10) are placed on a conveyor (1) and individually isolated from each other. A high energy laser (3) directs impulses at each object (10') to induce vaporisation of the material. A second laser (5) is aimed at the vapour cloud (11) to excite the latter (11). The emitted radiation is recorded by a spectroscopic detector (6) to determine the type of plastic. Appropriate information is fed to an analyser and control unit (8) operating a sorting device for the different materials. Claimed appts. includes a pulsed laser (3) above the conveyor (1) directing a beam through an optical arrangement (4). The second laser (5) beam is reflected by the same optical arrangement and is coincident with the first beam. A spectral analyser (6) is focussed by a second optical system (7) onto the meeting point of the laser beams (3, 5) with the vapour cloud. The lasers (3, 5) and spectral analyser (6) are connected to an analyser and control unit (8) which controls the separating device (9) relative to conveyor speed.

Title: Belt grinding unit
Inventor: REICHENBACHER WINFRIED DIPL IN
IPC: B24B21/00
Filed: 1993-04-07
Abstract: The invention describes a belt grinding unit which can be attached to mechanical machines and connected to their work spindle, having an endless grinding belt (3) which is guided over axially parallel deflection rollers (1, 2) and on the inner side of which is arranged a pressure shoe (7) which is arranged centrally actively between the two deflection rollers (1, 2), and having a drive spindle which is arranged coaxially with the work spindle of the machine.

Title: Ballast for LV halogen or Mercury@ discharge lamp - has energising transformer with core without air gap and two coil groups
IPC: H02M7/53846
Filed: 1993-05-26
Abstract: The appts. has a ballast whose output voltage is controlled with a self-oscillating half-bridge circuit and an inductivity of a load transformer. An energising transformer (38) for a transistor (15,16) has an extra coil for generating an orthogonal field, affecting its saturation remanence and thus its transform frequency. The energising of the extra coil takes place by a magnitude proportional to the effective voltage at the load. The magnitude is derived from an extra coil (21) of a load transformer (20). The control is made by the electric state between the transformer frequency, inductive resistance of the load transformer coils, and the proportional value of effective voltage at the load. ADVANTAGE - No component failure tendency. Simple energising transformer design.
Patent DE-4323922-A1 (DE)
Title: Honeycomb structure, preferably for a composite material in sheet form, a composite material and a process for producing such a composite material
Inventor: KUN JOSEF ATTILA
IPC: B32B3/12
Filed: 1993-07-16
Abstract: Honeycomb structures are used, inter alia, in caravans in order to keep their towing load as low as possible. A disadvantage of known sandwich profiles is the adhesive bonding of the core and outer layer, which consist of different materials, for example metal and a fibrous composite material, because alternating flexural loading causes the outer layer to buckle, become detached and lose its supporting function. The novel composite material is to be adequately resistant to bending and shearing in spite of a low density. The composite material (1) comprises strips (5) which run in a curved form and are firmly bonded to one another over the broad area of the contact surfaces. Openings (10) pass through the material of the strips (5). The said openings are of a slot-like design, and their edges are bent up in the manner of beads. The beads (11), produced by the bending up of the edges of the openings (10), of neighbouring strips (5) engage in one another in a spoon-like manner, at least over part of their circumference. The openings (10) extend on both sides of a bending line (13). The openings (10) are penetrated by a filling material (21), which is located in honeycomb chambers (15) and forms a one-piece part, so that high resistance to bending and shearing is obtained. <IMAGE>

Title: Lockable freewheel coupling for children's vehicles
IPC: B62K9/00
Filed: 1993-07-29
Abstract: The lockable freewheel coupling (100) for children's vehicles, in particular for the front wheel of a child's tricycle, comprises a hub sleeve (1) which is connected positively to the wheel, bears a click toothing (12) on the inner surface of a central recess (9) and together with a click-and-pawl arrangement (13, 14), which is arranged in the central recess (9), forms a freewheel coupling in which the freewheel is basically activated when the vehicle runs freely or when the driving direction corresponds to the rearwards direction of travel. The freewheel can optionally be locked by means of an additional, axially displaceable driver sleeve (26) which has a hexagon inner profile (29) in that the driver sleeve (26) is pushed manually onto a driver bushing (22) which is connected in a rotationally fixed manner to the wheel (7) and has a hexagon outer profile (25), with the result that the torque which is introduced via the pedal cranks can optionally be transferred rigidly to the wheel (Fig. 1). <IMAGE>

Abstract: Coupling device (2) for coupling towed devices (1) or vehicles - in particular those for agricultural purposes, such as e.g. field sprayers, to traction vehicles or tractors with a tow bar (4) which is arranged between the traction vehicle or tractor and towed device (1) or vehicle and is connected to the traction vehicle or tractor and to the towed device (1) or vehicle in each case with a joint (6, 7) which has an upright pivot axis (5, 8), the tow bar (4) for the one joint (7) being assigned a control device and/or locking device (11) by means of which the movement possibility of one of the tow bar joints (7) can be controlled while travelling. In order to achieve synchronous running of the towed device when cornering while maintaining the possibilities of gradient adaptation and laterally-offset parallel travelling in a simple way there is provision for the control device and/or locking device (11) to be assigned only to the joint (7) which is located between the tow bar (4) and the traction vehicle or tractor (Fig. 2). <IMAGE>

Patent DE-4330182-A1 (DE)
Title: Bellows seal
Inventor: NAKAJIMA TATSUO
IPC: F16D3/84
Filed: 1993-08-31
Abstract: A joint boot 1 is prepared by injection-molding a flexible thermoplastic polyester elastomer composition obtained by blending 20 - 99% by weight of a thermoplastic polyester elastomer and 80 - 1% by weight of a rubber. The modulus of tensile elasticity of the thermoplastic polyester elastomer composition may be in the range of 30 to 400 kgf/cm<2>. According to this technique, the flexibility and permanent compression strain resistance, which have been insufficient in the molded joint boot made of a conventional thermoplastic polyester elastomer alone, can be improved. The ratio of the outer diameter of a crest adjacent one end of the boot to that of a crest adjacent the outer end of the boot may be 1:1.0 - 0.5. <IMAGE>
Patent DE-4334534-A1 (DE)
Title: Radial bearing
Inventor: BUER GERALD DIPL ING
IPC: F16C33/34
Filed: 1993-10-09
Abstract: The invention relates to a radial bearing comprising an outer ring (1), an inner ring (4), between which rolling elements (2) roll on associated tracks, the rolling elements (2) and the bearing ring (1, 4) being in positive or frictional engagement with one another, thus avoiding slip between the rolling elements (2) and the bearing rings (1, 4). The bearing is distinguished by the fact that the outer ring (1) of the bearing has at least one groove (5), in which an elastic clamping element (8) which acts in the direction of the centre of the bearing, surrounds the rolling elements (2) at their running surface, revolves with them and presses them in the direction of the track of the inner ring (4). This ensures that the rolling elements (2) in the unloaded zone are driven with the aid of the clamping element (8) by means of the rolling elements (2) in the load zone. <IMAGE>

Title: Thread monitoring device
Inventor: MEYER URS PROF DR
IPC: B65H63/032
Filed: 1994-07-05
Abstract: A piezo-crystal is arranged in the run of a thread in such a way that the thread contacts it intermittently and, in so doing, deforms it in order to produce an output signal. This output signal has a fundamental frequency which depends on the periodicity of the contacts. The signal is transmitted via an energy/signal distribution system to a machine central control unit where it is analyzed. As a function of this analysis, a device can be actuated to interrupt the supply of material to the spinning location. <IMAGE>
