Title: Drafting rollers on spinning frame - have a drive-shaft constructed in sections which are screwed together
Inventor: STAHLECKER HANS
IPC: F16D1/02
Filed: 1992-02-21
Abstract: The bottom drive rollers on each drafting zone of a spinning frame are driven from a communal driveshaft. The driveshaft is constructed in short lengths, shaped at one end for the bearing ring, and then reduced in diameter in two steps, with a cone between. Finally, it is threaded to fit into the threaded bore of the next section. One of the diameter reductions is a press fit to the next section, and the other diameter reduction allows free play. Pref. end section (2) fits into the opposite end of a similar section (3) to form a driveshaft (1). The bearing ring (16) fits against the end of the section (3). Section (2) is reduced in dia. (b) for a short length (9) to form a press fit into the bore (15) of section (3). Short cone (10) provides a longer reduced diameter (11), which has free play (14) in the bore (D), before the thread (13) on diameter (c) is arranged to fit the interior thread of the final bore and end gap (6) of the section (3). ADVANTAGE - The difficulty of an exactly round circumference in a long length of shaft is overcome. The sections are fitted together in a design to avoid working loose. The sections fit together to form the very long length of a spinning frame.

Title: Electronic monitor to measure amount of wear on brake lining - has wedge in hole through brake lining displaced as lining wears to operate potentiometer in brake pad support
Inventor: BREARLEY MALCOLM
IPC: F16D66/02
Filed: 1992-08-07
Abstract: The brake lining (1) has a hole (4) through its entire thickness and through the support plate (2). A wedge (11), with wider end towards the braking surface (3), inside the hole is displaced as the brake lining thins. The inner end of the wedge displaces the operating slider (10) of a potentiometer mounted in the support plate. A simple circuit computes the brake lining thickness. Thermal insulation mountings for the potentiometer reduce thermal effects from the braking. An alternate design uses a plunger, displaced by brake wear, operating a rotating potentiometer via a rack and pinion coupling. The vehicle braking system can even out the brake wear over a time period, via the computed measurements. ADVANTAGE - Accurate brake wear indication, improved brake management.

Title: Headlamp, e.g. fog-lamp for car - has reflector to project horizontal band of strong images at outer edges and smaller images in between
Inventor: BERTLING JOHANNES-GERHARD DIPL
IPC: B60Q1/20
Filed: 1992-12-03
Abstract: The fog-lamp has a reflector which emits scattered light in a horizontal plane but which takes the form of several parallel beams in the vertical plane. The emitter is arranged so that its longitudinal axis is parallel to the optical axis of the reflector. The apex of the reflector is arranged so that it reflects light from the emitter as convergent beams in the horizontal plane, generating strong images of the emitter at the edges of the illumination. Away from the apex of the reflector, the light is reflected as progressively less sharply convergent beams, the greater the distance from the optical axis, generating a horizontal band of smaller images. All the images lie below a light-dark boundary. ADVANTAGE - Despite small reflector size, illumination over wide solid angle, esp. in side areas.

Title: Orientation device for weld studs
Inventor: WALKHOFF GUENTER
IPC: B23K9/20
Filed: 1993-02-10
Abstract: The orientation of weld studs with the point to the front is known with simultaneous separation and feeding to a further-processing station only via complicated rotary table movements. This orientation and feeding of the weld studs is to be effected in a simple but nonetheless reliable manner with the novel device. The object is achieved by virtue of the fact that a slide (3) is attached after the the feed passage (1). The slide (3) moves in timed sequence between the feed passage (1) and the stud-discharge opening, (11) and its receptacles (4) or (12) correspond either with the feed passage (1) or with the stud-discharge opening (11) and the receiving passage (8) of the rotary disc (7). The device guarantees that an orientated stud is always ready for further processing. <IMAGE>

IPC: B03B9/06
Filed: 1993-03-04
Abstract: In the sorting of mixed refuse with a high plastics content from the areas of industrial refuse, household refuse and building-site refuse, which contains a high proportion of plastics, for example plastic in the form of films, blow mouldings, cartons and foams and at the same time metals, composite materials, foreign materials such as glass, stones, ceramic, wood, leather, textiles, the diversity of the materials and forms of materials present give rise to the difficulty that virtually no single-material end products can be achieved by conventional manual sorting. By the use of various automatically operating treatment stages and the inclusion of special sorting processes for the plastics, the recovery of single-material end products from the material of complex composition fed in is successfully accomplished. <IMAGE>
