Title: Apparatus for smoking cigarettes
Inventor: BURGHART HEINER
IPC: A24C5/34
Filed: 1985-10-22
Granted: 1986-09-11
Abstract: In an apparatus for smoking cigarettes, the piston (2) in the smoking cylinder (1) is driven by means of an electric stepping motor (7) which receives a frequency-modulated pulse sequence for each working stroke of the smoking cylinder (1, 2), from a digital microcomputer-based control device (20). The average frequency of the pulses determines the drawing time, the total number of pulses determines the drawing volume and the modulation profile determines the drawing profile of the working stroke. All three parameters can be preset via the control device (20) by means of digital signals, with great accuracy and without mutual influence (Figure 2). <IMAGE>

Title: Additional switch for surface mounting on a line protection circuit breaker
IPC: H01H71/02
Filed: 1988-06-13
Granted: 1989-11-09
Abstract: The additional switch (1) is intended for surface mounting on a line protection circuit breaker (2). In the case of such additional switches, it is desirable to be able to carry out the setting to operate as an auxiliary switch or signal switch and/or relative auxiliary switch not only before surface mounting on an associated line protection circuit breaker (2) and/or before assembly with further such auxiliary switches and signal switches, but also subsequently as well, in the assembled state, on the wired-up apparatus, without any additional installation tasks. This is achieved in that a freewheeling device (11), which can be raised as required by means of a coupling element (12), is arranged between the operating toggle (4) and the locking device (7) of the additional switch (1). The coupling element (12) is constructed as a connecting shoe (28) which can be plugged on and, when the connecting shoe is plugged on, is fitted on its upper end surface with the type designation "Hi" designate the function as being an "auxiliary switch". In this function, the original function of the additional switch (1) as a "relative auxiliary switch" or signal switch, which is designated by the type designation "RHi" on the end surface of the operating toggle (4), is covered by the connecting shoe (28) so that the respective function of the additional switch (1) can easily be identified just on the basis of the designations on the connecting shoe (28) and on the operating toggle (4). <IMAGE>

Patent DE-4102356-C1 (DE)
IPC: D21F3/02
Filed: 1991-01-26
Granted: 1992-01-23
Abstract: In the press section of a paper making machine, there is a central roll, a first press roll beneath and a second press roll above the central roll defining respective first and second press nips. The first press nip or both nips may be extended nip presses. A water impervious press belt travels through the first press nip around the central roll and through the second press nip, meeting the central roll before the first nip and leaving the central roll after the second nip. A felt belt conducts the web to be dewatered into the first nip along with the press belt. The felt belt separates from the web after the first nip. Following the second press nip, the press belt carries the web to a place of removal where a dryer wire picks up the web. The distance from the second press nip to the place of removal is at least equal to the circumference of and is preferably greater than the circumference of the central roll. The path of the press belt from the second nip to the removal place may be bent by a deflection roll.

IPC: F16D69/00
Filed: 1991-06-13
Granted: 1992-12-10
Abstract: The invention relates to a friction lining, intended in particular for brake systems, with a friction element made of asbestos-free material and an abrasive element (6) made of abrasive material (1) with a natural-resin or synthetic-resin thermosetting binder. The invention calls for an abrasive element to be incorporated in the friction element which, as wear of the friction lining advances, enables the frictional properties of the surface which presses against the lining to be regenerated at intervals.

Title: Lifting and sliding car-roof - uncouples lifting lever on moving from ventilating to open position and engages with guide rail on top of fixed roof
Inventor: LANG THOMAS PH
IPC: B60J7/043
Filed: 1992-11-19
Granted: 1993-11-25
Abstract: The roof is mounted at the front on a slide at each side and which travels along a guide at a lower level than the fixed roof portion in the lengthwise direction. Levers on both sides engage with the rear half of the roof so as to lift its trailing edge above the fixed part of the roof, over which it slides into the open position. On sliding the roof (12) from the ventilating position into the open one, the levers (26) are uncoupled from it. Guide members (34) at the roof rear end then engage with a lengthwise rail (37) mounted above the fixed part of the roof (10). On approaching the ventilating position from the open one, the members uncouple from the rail and the levers engage again. The levers can have coupling trunnions (27) at their top ends by which they engage in an open-ended guide (28) fixed to the roof near its trailing edge (32). USE/ADVANTAGE - The car roof is flush with the fixed part when shut, while freeing the opening for the maximum amount when open.

Title: Multiple actuating device with regulator on the inlet side
Inventor: SCHWARZ WALTER
IPC: F23N1/02
Filed: 1993-11-05
Granted: 1995-03-23
Abstract: In a multiple actuating device for gas/air combination control of a combustible gas/air mixture in a combustion heat generator according to the servo principle, the regulating valve and the safety valve (8) are each designed as double seat valves, the regulating valve being arranged at the inlet of the gas flow to the multiple actuating device and having a diaphragm plate at the bottom end of the valve stem. The diaphragm plate is provided at the margin with an encircling, sealing control diaphragm (2) and is acted upon at its underside by the control pressure pst and at its top side by a mean pressure pm from a mean-pressure space (7), which is less than or equal to the inlet pressure pe of the inflowing gas stream at the inlet. In this arrangement, the inlet pressure pe of the gas stream can act via a longitudinal bore of the valve stem of the regulating valve on the control-pressure space (4), the top boundary of which forms the underside of the diaphragm plate of the regulating valve, and the control-pressure space (4) can be acted upon on the other side by the burner pressure pbr via a control valve (12) which can be actuated by the first regulating diaphragm (13), to one side of which the burner pressure pbr is applied. Thus less sensitivity of the regulating system to rapid pressure fluctuations from the burner side as well as less dependency of the valve functions on the inlet pressure are achieved. In addition, the energy present in the gas pressure can thereby be optimally utilised for the control pressure. <IMAGE>

Abstract: Сущность: нож, предназначенный для резки листового материала и приводимый в возвратно-поступательное движение. Нож имеет первую и вторую боковые режущие грани, расположенные под наклоном друг к другу и образующие по линии пересечения удлиненную режущую кромку. Режущая кромка смещена от базовой плоскости, проходящей посредине между боковыми образующими сторонами ножа, при этом первая грань находится в указанной базовой плоскости симметрии, отходя от соответствующей боковой стороны тела ножа к режущей кромке. По меньшей мере первая режущая грань имеет тонкое покрытие из твердого материала, твердость которого выше чем у материала основы ножа. В процессе резки вторая режущая грань подвергается перезаточке, так, что режущая кромка формируется из твердого материала покрытия первой грани. В результате многократной перезаточки лезвия по второй режущей грани режущая кромка постепенно смещается к базовой плоскости и затем выходит за нее на другую сторону, что обеспечивает относительно большой срок службы ножа. 2 с. и 1 з.п. ф-лы, 9 ил.
