Title: Coordinate input unit controlling cursor position on screen - uses rotatable ball in housing and partly extending through opening, and two rotary shafts defining specific angle between them
Inventor: NIITSUMA HIROFUMI
IPC: G06F3/0354
Filed: 1992-07-21
Abstract: Two shafts rotate in connection with the rotation of the ball (10). A spring (19) tensions the shafts against the ball. A detector (20,21) senses the rotation extent of one of the shafts. On the housing (11) a p.c.b. (15) is fitted for the rotation detector. A cursor position or similar is controlled on a display screen according to the extent of rotation of the ball in each direction. At least three holder elements (16) retain the ball via at least three retaining areas in the housing (11) which accommodate the holder elements from one side of the housing and on which the p.c.b. is fitted. The holder elements are also kept in contact with the ball by a shaft holding area in the housing. ADVANTAGE - Ball holder elements can be fitted without disturbing sliding ability of ball.

Title: Automatic yarn winder - has single arm arrangement to place both yarn ends in splicer.
Inventor: HORAK DIETER
IPC: B65H69/00
Filed: 1992-09-24
Abstract: A process to lay an end of yarn in a splicer or knotter on a winding machine, when connection between supply cop and wound cone is absent, and so that the reconnection can be made. The yarn end from the cop and from the cone is laid in the splicer by the single arrangement. The appts used is also claimed. Typically, the single arrangement is a suction tube (25) which swivels at (26), having an open end (27) with a sensor (32) inside, to detect yarn presence. The tube can reach at the lower position, to place the yarn end (6a) from the cop (5) into the splicer (10), in such a manner that the yarn is held in the grip (11), while an upper yarn end (6b) is drawn from the cone (15). This is achieved when the tube (25) rises (28) to meet the end (31) of the yarn guide (29). The flat shape of the guide is so formed to draw the yarn end away from the winding on the cone (15). ADVANTAGE - The arrangement is compact and efficient.

Title: Rod sieve calibration for screw press separators
Inventor: EICHLER DIETRICH DR
IPC: E03F5/14
Filed: 1992-12-21
Abstract: To calibrate rod sieves, the dia. of the sieve material which is produced in a small structure is increased by plastic distortion to the required dimensions.Also claimed is an appts. with a hydraulic cylinder to deliver the required forces for the plastic distortion. It pushes a cone into a multipad chuck, and the forces are taken up by linear ball bearings.Plastic distortion corrects any distortion in sieve structure after holding rods have been welded into place.Pads are linked to the baseplate through swing rods, and held by springs. The number of pads matches the number of rods welded to the sieve. The sieve is pushed over the multi-pad chuck so that the rods lie at the centre of the pads.

Title: Device for simulating the body of a vehicle
Inventor: TREPTOW NORBERT
IPC: G09B25/02
Filed: 1993-04-08
Abstract: A device (1) for simulating the body of a vehicle, in particular the body of a passenger car, consists of rigid frame components (2 to 10) which can be securely connected to one another and are arranged on its inside for the purpose of interior cubing equipment components (21). According to the invention, individual frame components (2 to 10) can be slid or pivoted with respect to the rest of the device (1). For example, hinges (11, 16) permit the lateral assembly frames (5, 6) which simulate the doors to pivot; additionally longitudinal guides (13) permit lateral displaceability of the assembly frames (5). A pivot bearing (14/15) ensures the pivotability of an assembly frame (7) for a dashboard. The equipment components (21) are additionally connected to the frame components in a releasable fashion. The device (1) according to the invention provides a flexible, reusable cubing structure constructed according to the construction kit principle which permits a simulation of a passenger compartment with largely real functional conditions. By virtue of the good accessibility and the easier handling there is a saving in time and cost with respect to conventional cubing structures. <IMAGE>

Filed: 1993-05-03
Abstract: In the system to carry a paper web to be dried, in a papermaking machine, the longitudinal sealing bar (29) has a concave sealing surface (B) matching the mantle (10a) of the deflection roller. Both sealing bars (28,29) pref. have a concave sealing surface (B) matching the mantle (10a) of the deflection roller, with a surface length (B) at least 3% of the roller mantle circumference, or 4-6%. The sealing surface has longitudinal grooves forming a labyrinth seal. The separate sealing bars (28,29) have a flat outer surface (28a,29a) towards the blanket (15) with a length about equal to the curve length (B) as seen in cross section. The separate sealing bar (28,29) assembly is pref. secured to a suction box (14) by a T-groove or swallowtail joint, across the direction of web travel, for assembly and dismantling. An outer wall (17) and the outer surface (28a) of the first bar (28) form a smooth and flat surface parallel to the blanket (15) path or diverging from it at a small angle. USE/ADVANTAGE - The assembly carries the paper web, to be dried, together with a porous blanket. The recesses in the roller mantle generate sufficient underpressure to draw the air alone from the external suction boxes, without inner roller suction and central air extraction.

IPC: B62D6/02
Filed: 1993-05-28
Abstract: A valve arrangement for a hydraulic delivery device, in particular a steering-aid pump, is proposed which has a piston (15) displaceable as a function of pressure inside a bore against the force of a spring device (helical spring (41)). The outer wall of the piston (15) - for forming a slide valve - bears in a sealing manner against the inner wall of the bore (9) and thus the inner wall of the bore - as viewed in the axial direction of the bore - seals off orifices of passages (37, 61) from one another, the orifices opening out at a distance from one another. The valve arrangement is characterized in that the piston is equipped with a section acting as a seat valve. <IMAGE>

Patent DE-4322214-A1 (DE)
Inventor: ARENZ RAINER DIPL ING
IPC: H01H71/50
Filed: 1993-07-03
Abstract: A lockable arrangement for a circuit breaker comprises a rotary drive (2, Fig 1), a pivotable switch actuating member 6 spring loaded in the on switching direction and a pivotable rocker arm 16 having a drive slot 8 engaging over the switch member 6 for transmitting motion from the rotary drive (2) to the switch member 6. A rotary coupling 50 between the rocker arm 16 and a handle (10) comprises two relatively rotatable parts having alignable recesses 13, 14 which are engageable with a latching element 15 of a displaceable blocking slide member 12 to enable the rotary drive (2) to be locked in the off position. Should the contacts be welded or retained closed, the coupling parts 50 are turned relative to each other against the action of a torsion spring when the handle (10) is turned towards the off position to cause the retaining recesses 13, 14 to be misaligned thereby preventing the blocking slide member 12 from reaching its blocking position which prevents the rotary drive (2) from being locked. <IMAGE>

Title: Electronic control system for metering fuel in an internal combustion engine
Inventor: MERGENTHALER ROLF-HERMANN DIPL
IPC: F02D41/12
Filed: 1993-07-12
Abstract: The invention relates to an electronic control system for metering fuel in an internal combustion engine. A signal (ti) for the quantity of fuel to be injected is produced in that a basic injection signal (te) and a signal (tUK') which is corrected by means of an adaptive correction factor (FKorr), for transition compensation, are logically connected. The adaptive correction factor (FKorr) is progressively adapted with the aid of a fuzzy logic (212) which evaluates the quality of the transition compensation with reference to selected characteristic variables. For example the central change (dL/dt) over time of the load (L) and the average value ( lambda M) of the air ratio ( lambda ) during a non steady state of operation of the internal combustion engine (100) serve as characteristic variables. <IMAGE>
