Title: Double-printing printer
Inventor: NARITA HARUFUMI
IPC: B41J3/60
Filed: 1988-01-12
Abstract: A double-printing printer has a feed roll (9) for the successive feeding of individual forms (3), accommodated in a feed pile device (2), onto a transport path (10) which is provided with pairs of reversible transporting rollers (11-13). Each individual form is firstly transported forwards past a printer unit (14) without printing. The individual form is then transported backwards and printed on its front. The individual form which has been printed on one side is then guided into a return path (17) which adjoins the transport path at a point ahead of the printer unit. When passing through the return path, the individual form is turned and fed back to the pile device by means of a turning unit (21) arranged above the pile device. Finally, the individual sheet which has been turned is transported forwards and, in turn, is printed on its back by the same printer unit. <IMAGE>

Title: Method for separating a printed circuit board blank
Inventor: FROST GUNTER
IPC: B23D31/00
Filed: 1988-03-03
Abstract: Two separating pieces (3, 4) each having one separating edge (31, 41) which are aligned exactly parallel to one another in a separating plane (TR) are used for separating a printed circuit board blank (1). The printed circuit board blank (1) is pushed in between the separating edges (31, 41). Subsequently, at least one of the separating pieces (3, 4) is moved such that the separating edges (31, 41) are moved towards one another until they reach a limit position. In this case, the separating edges (31, 41) touch the surfaces (11, 12) of the printed circuit board blank (1) and exert a high pressure on the surfaces (11, 12), which pressure is sufficient to separate the printed circuit board blank (1). <IMAGE>

Patent DE-3832562-A1 (DE)
Title: Capacitive sensor device
Inventor: MEISSNER ROLF
IPC: G01N27/22
Filed: 1988-09-24
Abstract: The invention relates to a capacitive sensor device which can be used as a data acquisition system working without contact for all active media, especially for printing materials. The aim of the invention consists in the provision of a capacitive sensor device which allows the actuating distance to be increased, the sensitivity to external fields to be reduced and, thus, the accuracy of devices of this type to be increased. The object of the invention therefore consists in designing the capacitive sensor device in such a way that it generates measured values which can be evaluated, even at relatively large actuating distances, and has a smaller sensitivity to external fields. The object is achieved in that the transmitter plate and the receiver plate, to which the displaceable active medium is brought, are arranged between the transmitter, consisting of the oscillator and the clock processor, and the receiver, consisting of the amplifier, the band-pass filter and the rectifier circuit. <IMAGE>
Patent DE-3834650-A1 (DE)
Title: Safety clamping device driven by fluidic or electrical action of force
Inventor: DIMTER ERWIN
IPC: B25B5/16
Filed: 1988-10-12
Abstract: During the operation of semi-automatic and automatic machines, in particular circular metal saws, in which the workpiece is automatically clamped, the clamping stroke may only be so large that there is no space for a finger on account of an injury risk. 7 mm is permitted as a rule. If other material is constantly worked or if there are undersizes as well, the clamping stroke does not reach the material. The workpiece cannot be controlled, the saw blade breaks and injuries are the result. Many users also seek a solution for immediately recognising a situation in which the clamping pressure is too high and the workpiece, for example pipe or section, has become deformed. According to the invention, this is achieved by virtue of the fact that a contact or a stopless measuring system which stops the further operating sequence is fitted before the end of the clamping stroke. <IMAGE>

Patent DE-3908609-A1 (DE)
Title: Method and apparatus for the production of a tobacco strand
Inventor: BRAND PETER
IPC: A24C5/31
Filed: 1989-03-16
Abstract: A method and an apparatus for the production of a tobacco strand are described. To this end, a spread-out and loosened stream of tobacco is conveyed along a guide surface (24), under the action of blown air, to a suction strand conveyor (29) rotating in a tobacco channel (37), in which the tobacco fibres are collected to form a tobacco strand and are held by suction air. The suction strand conveyor (29) conveys the tobacco strand formed out of the strand formation zone (28) in the direction of its lengthwise axis. In the event of the occurrence of a strand blockage, which takes the form of occupation of the suction strand conveyor by tobacco fibres to an extent which exceeds a predetermined dimension and which is determined by a sensor means, for example a light barrier (53), the end section (24a) of the guide surface (24) is deflected by the displacement of a control member (39a), opening a bypass shaft (58), by which the flow of tobacco is diverted past the suction strand conveyor and past the tobacco channel along a diversion surface (59). The strand blockage in the tobacco channel (37) is eliminated by switching off the vacuum in the vacuum chamber (31). This can be assisted by blown air from an air slit (62). The invention is advantageously used in the elimination of blockages in cigarette strand machines. <IMAGE>
