Title: Circuit arrangement for monitoring a motor parameter
Inventor: FUELLEMANN KURT DIPL ING
IPC: H02H7/085
Filed: 1986-10-22
Abstract: A circuit arrangement for monitoring a motor parameter which is characteristic of the mechanical power or torque emitted by the motor or the device driven by it contains a measurement device which monitors the motor parameter and emits a corresponding measurement signal. A comparator circuit is furthermore included in which the measurement signal is compared with a required value signal. An actuating signal which corresponds to the relationship between the measured value signal and the required value signal is produced at the output of the comparator circuit. In order that the actuating signal is not corrupted if the mechanical losses in the device which is driven by the motor change, a memory circuit is provided which, at least at times, receives and stores a signal corresponding to the motor parameter, which signal occurs at a predetermined load state of the motor. In addition, a superimposition circuit (heterodyne circuit) is provided which receives on the one hand the stored signal from the memory circuit and on the other hand either the measurement signal or the required-value signal.

Patent DE-3641859-A1 (DE)
Inventor: NOLTE BERT DIPL ING
IPC: B65H33/02
Filed: 1986-12-08
Abstract: In the process of packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the specific batch size is at least identified or optionally pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article. The packaging batch is deposited on a conveyor belt and conveyed away. A stack support keeps the stack approximately vertical on its end face. The stack support is advanced in front of the stack at the conveying speed of the conveyor belt. As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the production machine, a separating device is introduced into the stack, with the result that the following portion of the packaging batch is temporarily halted. During this time, the separated stack is pushed, at the same height, into an open container via a slide track. Subsequently, the stack support is guided back to the separation point, and the separating device is retracted from the end face of the following packaging batch, after which the stack support once again takes over the vertical guidance of the packaging batch, until the next counting article has arrived at the separation point. The automatic packaging machine for letter envelopes and mailing wallets has several devices, by means of which the individual steps of the process are executed partly alone and partly in combination with one another.

Title: Adjustable rail fastening
Inventor: FASTERDING GUENTER DIPL ING
IPC: E01B9/68
Filed: 1987-03-16
Abstract: For track structures on solid ways, a new rail/sleeper fastening is proposed. For high-performance stretches of railways, the fastening is frequently designed in such a way that the "rail clamping" and "resilient bearing" functions or "height and lateral adjustability" functions are separated. The invention relates to a resilient, electrically insulated fastening of a ribbed plate (4) which supports the rail and has a screw (10) and a novel spring element (5, 6, 7) on a sleeper (2). Advantages are obtained by a smaller number of components, preassembly of all clamping elements, capacity for simple rail alignment during laying and subsequent maintenance. The novel fastening can be used for wooden, concrete and Y-steel sleepers, as well as in points (Fig.1). <IMAGE>

Title: Spectacle cleaning strip with moisture storage
Inventor: WENDT HEINZ
IPC: G02C13/00
Filed: 1987-05-19
Abstract: The spectacle cleaning strip is an alternative to the conventional, sufficiently known cleaning cloths. It is easier and also more effective to handle, because it can also be used for wet cleaning the spectacles or optical glasses. As a result of its mass production, it is designed to be a "disposable product" which for the user has the advantage that the spectacle cleaning strip is always clean. After several uses the conventional cleaning cloth is used up, because during each deployment the front and back of the cloth are affected, specifically by the dirt on the spectacles and the sweat (perspiration) of the hands. In the case of the cleaning strip according to the invention, only the intended cleaning side can come into contact with the spectacles. In contrast with the devices described in P 3705196.2 and G 7131136, the spectacle cleaning strip according to the invention is distinguished by its simpler and cheaper means of production as a mass-produced article. Because a bulky paper or the like is used as storage layer, the cleaning fluid which is applied to the cleaning layer and penetrates it, is sucked up by the storage layer, as a result of which the spectacle cleaning strip is ready for use for wet cleaning for a longer period of time.

Title: Homogeneous field magnet with profiled pole plates
Inventor: RIES GUENTER DR
IPC: H01F7/20
Filed: 1987-11-02
Abstract: The homogeneous field magnet contains a yoke which carries the magnetic flux and has two opposite pole shoes between which a highly homogeneous magnetic field is formed. The pole shoes are provided with pole plates which are profiled on their mutually facing sides and can be adjusted by means of mechanical adjusting devices for field correction. This field correction is intended to be capable of being carried out in a relatively simple manner. To this end, the invention provides that, on at least one of the pole shoes (11), the profiled pole plate is separated via a narrow correction air gap (15) from a base part (11b) of the pole shoe (11) facing the yoke, and the adjusting devices (21 to 27, 30) are constructed to tilt and/or bend the profiled pole plate (11c). <IMAGE>

Title: Electrooptic display device
Inventor: CREMERS ROLF DR
IPC: H05K3/32
Filed: 1987-12-23
Abstract: An electrooptic display device (11) having electrical connection of its display cell (12) to a printed circuit board (17) situated therebehind via a multi-conductor coupling element (19) is intended to have coupling contacting such that in the interest of a low requirement for installation space in the plane parallel to the cell face-plate (15) it is possible to prevent projections of the printed circuit board (17) or of the coupling element (19) beyond the front rim of the face-plate (15). For this purpose, the printed circuit board (17) is held approximately at right angles to the face-plate (15) in a manner pressed against the connecting edge region (14) of the face-plate with the interposition of the coupling element (19). In order to prevent uncertainties in contacting between the coupling element (19) and the ends of the printed circuit board conductor tracks (18), the latter are extended electrically around the end edge (21) of the printed circuit boards by means of L- or U-shaped connecting clips (22). The connecting clips (22) can be applied as a complete set still connected to one another via jumpers (27). The set is not subsequently split up until the flange-type jumpers are separated into the electrically separated printed circuit board connecting clips (22). Owing to the transverse orientation, even the requirement for a large printed circuit board (17) on grounds of circuitry does not have the result that the installation surface of the cell (12) has to be overlapped on the side by the printed circuit board (17). <IMAGE>
Patent DE-3800284-A1 (DE)
Title: Coffered ceiling
Inventor: LUDWIG PETER ING GRAD
IPC: E04B9/26
Filed: 1988-01-08
Abstract: The invention relates to a coffered ceiling having fire-resistant elements borne by load-bearing rails and coffers arranged beneath the fire-resistant elements. The load-bearing rails have a cross-section in the form of an upside-down U. Bearing profiles in the form of an upside-down U can be placed onto the load-bearing rails, which bearing profiles exhibit bearing legs which are each angled off outwardly from one or both of their U-legs and are intended for the fire-resistant elements. This achieves the load-bearing structure for the fire-resistant elements and connectable clamping rails in, on the one hand, load-bearing rails and, on the other hand, bearing profiles, which can be adapted to the installation conditions, with satisfactory bearing for the fire-resistant elements. <IMAGE>
