Title: Condition of automotive filters monitored in situ by differential pressure switch - precluding unnecessary filter changes and lowering operating costs
Inventor: UHL GUENTER DR
IPC: B01D46/46
Filed: 1992-07-27
Abstract: In appts. to monitor the accumulation of substances in automotive filters, the novelty is that a pressure differential switch (4) is activated by a filter (1) to produce a signal by means of a display (5,6) when a given threshold is surpassed. Further that the switch (4) is only activated in combination with a tachometer (8) and an evaluation scale (7), which only then passes the incoming signal from the pressure differential switch (4) to the display (5), if the engine speed is within a small pre-determined window. Pref. the display (5) is coupled to a reverse switch (12) activated by a signal from the differential pressure switch (4) to link two lamps (5,6) with a power source (13). USE/ADVANTAGE - The appts. indicates when oil and air filters have ceased to operate with optimum efficiency. Operating costs are reduced by changing filters on condition instead of an a fixed time-scale.

Title: Automatic yarn winding machine - has screen to prevent yarn end from cop in proximity entering the yarn end release mechanism.
Inventor: BUCKEN RENE
IPC: B65H67/08
Filed: 1992-09-05
Abstract: On an automatic yarn winding machine there is a transport system to deliver cops to be crosswound on a reel. The cops are held on support plates in transit, and pass through a yarn end release mechanism, in preparation for the take-up mechanism on the winder. In order to prevent the air pressure from the release mechanism affecting the cop in proximity a screen is attached to the yarn end release mechanism, in the direction of the following cop. The cops are forwarded to the winder on a conveyor. They are supported on cop plates (1), with a central vertical short spindle, and they pass along in close proximity to each other. ADVANTAGE - The yarn end is placed in a position on the cop where it can be readily released to the winder mechanism. The screen prevents this being disturbed on the cop in close proximity.

Title: Cleaning polymer contaminated machine parts - involves heating parts in autoclave and removing residuum of polymer thermal breakdown by flushing with superheated steam
Inventor: MIGNANI MARIO
IPC: B08B7/00
Filed: 1992-09-18
Abstract: The contaminated machine parts are allowed to heat up in an autoclave (2). As soon as a predetermined temperature of 350-400 deg. C is attained, superheated steam (11) at a temperature of 400-450 deg. C is admitted to the autoclave through an inlet pipe (8) and mixes with the residuum originating from thermal breakdown of polymer on the parts to be cleaned. The mixture of steam and residuum escapes from the autoclave through the outlet pipe (8). Finally, air (12) at a temperature of 400-450 deg. C is switched through the inlet pipe (7) into the autoclave to prevent the development of polymer incrustations. USE/ADVANTAGE - Cleaning machine parts contaminated with polymers with minimal production of harmful waste products. Cleaned parts are not damaged. Low capital and running costs.

Inventor: GILLMANN HANNO DR ING
IPC: B07C3/06
Filed: 1993-01-28
Abstract: In the method of the invention for sequencing parcels in mail-sorting facilities having rows of stacking compartments, a sorting plan is used for sorting the parcels in which an overfilling of the individual stacking compartments is avoided so that, during one sorting procedure, the stacking compartments are not emptied, and that, after a sorting procedure has ended, an in-sequence transfer of the parcels is effected from the stacking compartments into a conveying device disposed opposite the stacking compartments or into containers.

Title: Detection and decision device for combustion engine misfiring - applies correction to engine control when misfiring is detected at intervals of less than predetermined min.
Inventor: FUKUI WATARU
IPC: F02D35/02
Filed: 1993-02-04
Abstract: A crankshaft reference position signal (1) is used in conjunction with the outputs of sensors (2) of engine operating conditions and of an ion current detector (20) monitoring the state of combustion in one cylinder. The control parameters of the engine are corrected (31) on the basis of a misfiring decision signal (Q) produced (34) when the interval (33) between misfires is shorter than a predetermined limit. If misfiring cannot be suppressed by such correction, fuel injection into the affected cylinder is inhibited to prevent discharge of unburnt fuel in the exhaust. ADVANTAGE - A highly dependable decision on misfiring can be guaranteed without noticeable increase in complexity of the logic.

Title: Circuit arrangement for controlling or regulating the starting (acceleration), braking and rotation speed of a three-phase asynchronous motor
Inventor: REITER ENGELBERT
IPC: H02P23/24
Filed: 1993-03-27
Abstract: The invention relates to a circuit arrangement for controlling or regulating the starting, braking and rotation speed of a three-phase asynchronous motor, comprising a regulator whose first input is connected to a device for detecting the actual rotation speed of the motor, whose second input is connected to a device for presetting the required rotation speed, and whose output is connected to a plurality of power semiconductors, such as triacs, alternistors or thyristor pairs connected in opposition in parallel, in order, via a phase-gating controller, to control the three-phase supply fed to the motor turns from the terminals of the motor, a rotation direction reversing circuit furthermore being provided in such a manner that the assignment of at least two phases to two motor turns can be interchanged, and, in the case of at least some of the phases, the assignment to the respective motor winding taking place by the power semiconductors being turned on or turned off by means of the control and regulating arrangement. In order to achieve a construction which is as simple and compact as possible, it is provided that one phase of the terminal voltage is connected directly to one motor winding, without the interposition of power semiconductors. As a result of the reduction in the number of components achieved in this way, it is possible with particular advantage to accommodate the controller on or in the motor housing, particularly in the terminal box. <IMAGE>

Title: Device having a tensile-stressed web of composite material and apparatus for its production
Inventor: SPORS HERBERT DIPL ING
IPC: B29D29/00
Filed: 1993-07-07
Abstract: A device of this type is intended to take up high tensile forces with little elongation. Such a tensile-stressed web has an intermediate layer consisting of a flexible linear structure embedded in elastically deformable outer layers. To achieve high load-bearing strengths with little elongation, it is proposed to design the linear structure as a core braid comprising a plurality of filament bundles, the filaments in the individual bundles running untwisted next to one another and substantially parallel. For a particular field of application, it is additionally proposed to design the tensile-stressed web as a seamless, continuous loop. Passed through the opening of the loop are at least two deflecting means, which can transfer tensile forces into the loop. The braiding repeat of the core braid is in a certain relationship with the effective deflecting arc of one of the deflecting means. For producing the loop, it is proposed to lead the respective windings of the linear structure over individual discs which can rotate with respect to one another and the profiling of which on their outside diameter determines the effective deflecting arc of the finished loop deflection.

Filed: 1994-03-04
Abstract: The present invention relates to a photosensitive resin containing at least one group of the formula (1) in the molecule, <IMAGE> in which n is an integer from 1 to 10. Since the novel photosensitive resin contains at least one azide group in the molecule having an absorption range above 300 nm, the resin is highly sensitive.
