Title: Device for fixing adhesive perforated tape on paper sheets and other documents to be printed
Inventor: MUELLER THOMAS
IPC: B42C3/00
Filed: 1988-03-08
Abstract: "Continuous stationery without perforations" (P 3729650.7) was developed in order to avoid the tear-off strips on the outer edges of paper sheets in computer continuous stationery. In this continuous stationery, the rows of perforated tapes arranged on the long edges of the paper sheets and serving for transport are fixed to the lower long edges of the individual paper sheets by means of an adhesive tapes about 1 cm wide, coated with adhesive and located in each case beside the rows of perforated tapes, so that a cohesive connection exists between the individual paper sheets and the two rows of perforated tapes. It is the object of the device to fasten the perforated adhesive tapes on the underside of the paper sheets. This is achieved by means of a device (3a) or (3b) which isolates the individual paper sheets in cyclic fashion from a stack of paper sheets (2a/b) and inserts them into the gap of a pair of rolls (7) (11). By means of guides (10a/b/c/), the two perforated adhesive tapes (1) are placed respectively to the left and the right of the roll gap, so that they are pressed onto the lower, lateral edges of the paper sheets by a rotatory movement of the pair of rolls. By means of any number of repetitions of this arrangement, "X" additional copies can be attached to the original. <IMAGE>

Title: Process for drying a material web and apparatus for carrying out this process
Inventor: WANKE WILHELM
IPC: D21F5/18
Filed: 1988-03-10
Abstract: The invention relates to a process and apparatus for drying a material web, especially a paper or cardboard web. The material web runs alternately, together with a supporting band, over heatable drying cylinders, on which contact drying takes place, and over guide rollers which are touched by the supporting band. Downstream of each contact zone, the material web is guided along a re-evaporation space which is relatively wide in the web running direction. This is followed by a hot-air supply zone, in which hot air flows in a turbulent state along the paper web opposite to the web running direction and is thereafter received by a waste-air chamber.

Title: Rod for holding and guiding tea bags
IPC: A47G19/16
Filed: 1988-03-17
Abstract: Although tea bags have been produced and used for many years, a utensil which enables simple and clean use has still not been developed. The rod for holding and guiding tea bags is constructed such that the string situated on the tea bag can be wound around a deformation and/or a thickening on the rod, with the result that the user is no longer obliged to touch the moist tea bag after use, or the string fastened to it, or the paper attached to the end of the string, in order to remove the tea bag from the tea glass/vessel after use. The deformation and/or thickening furthermore serves to prevent the paper fastened to the end of the tea-bag string from slipping down when the latter is pushed over the upper end of the rod.

Title: Countercurrent broken-glass solar collector
Inventor: COST KARLFRIED
IPC: F24S10/80
Filed: 1988-07-01
Abstract: Technical problem of the invention. The energy losses due to heat conduction, convection and heat radiation on the side of the solar collector facing the sun are to be kept down. The collector is to be inexpensive. Solution of the technical object. The solution is characterised by the construction of the collector in three layers, at the top a plurality of layers of broken glass, thereunder a layer with a relative flow resistance and at the bottom a layer with a low flow resistance. The heated air is sucked off at the bottom, and at the top ambient air flows into the countercurrent broken-glass solar collector. By using broken glass as an essential component, the countercurrent broken-glass solar collector is very cheap. Area of applicaton. Heating of air of ambient temperature to a considerably higher temperature. <IMAGE>
Patent DE-3823015-A1 (DE)
Title: Filter
Inventor: STRAUSS WERNER
IPC: B01D33/46
Filed: 1988-07-07
Abstract: In the known rotary filters for separating a solids/liquid mixture, the scraper required for removing the filter cake from the filter surface has been connected to the carrier to be adjustable, but has been connected rigidly, however. However, the readjustment of the scraper is associated with an increased expenditure in terms of labour, time and costs and a removal of the filter cake from the filter surface is not always optimally ensured, since, because of wear on the scraper and/or the uneven movements of the filter disc or the filter drum, filter cake is drawn into the free space between the filter surface and the scraper and is not caught by the scraper. This is avoided according to the invention in a simple manner by the scraper (3) being connected to the carrier (5) by an elastically resilient element (6). As a result, the scraper is always pressed to conform to the filter surface and can thus follow the uneven movements of the filter disc or the filter drum, so that, without a special readjustment of the scraper, optimal filter cake removal is ensured. <IMAGE>

Title: Starting coupling (clutch) for a single-phase synchronous motor
Inventor: RUEHLEMANN JOACHIM
IPC: H02K7/118

Abstract: In order to delay the starting of the load (10) over a plurality of revolutions of the synchronous motor, a starting coupling for a single-phase synchronous motor has a threaded pin (16) which is connected in a rotationally fixed manner to the output drive shaft (11) of the synchronous motor, a nut (18) which screws itself along the external thread (17) of said threaded pin (16), and a sleeve (13) which is connected in a rotationally fixed manner to the load (10), engages over the nut (18) by means of a circumferential radial shoulder (28) and is connected in a rotationally fixed manner thereto by means of an axial sliding guide (27). A spring element (20, 21) is supported between the nut (18) on the one side and the radial shoulder (28) on the sleeve (13) or an annular flange (24) (which lies on the opposite side of the nut (18)) on the threaded pin (16) on the other side. During starting of the synchronous motor, the nut (18) is screwed forwards with the spring element (20, 21) being compressed, and the sleeve (13) and thus the load (10) are driven without any slip, with the forward motion of the nut (28) being blocked, when the spring element (20, 21) is correspondingly compressed (Fig. 1). <IMAGE>

Patent DE-3903943-A1 (DE)
Title: Method and devices for examining the relative radiation flux density of electromagnetic beams, especially for determining the radius of Gaussian laser beams
Inventor: SCHWEIGER GUSTAV PROF DIPL ING
IPC: G01J1/42
Filed: 1989-02-10
Abstract: For determining the radiation density of electromagnetic beams, especially for determining the radius of Gaussian laser beams, a scattering surface is placed in the beam. Beam and scattering surface move relative to each other. The light scattered by the scattering surface in a specific angular range reaches a detector which enables the measurement of the random fluctuations of the scattered light, for example by measuring the time-autocorrelation function of the scattered light. These random fluctuations are produced because the scattering properties of the scattering surface have a random location dependence (for example because of surface roughnesses) and the radiation flux density is likewise location-dependent. By means of the relative movement, parts of the scattering surface pass through regions of different radiation flux density. If the relative velocity is known, the beam radius can then be determined in a simple way by measuring the time-autocorrelation function of the scattered radiation in Gaussian beams. Deviations from Gaussian beams can thus also be determined.

Title: Input stage for an IR distance measuring system
Inventor: REIMANN HUBERTUS DR
IPC: G01S7/4912
Filed: 1989-04-14
Abstract: The invention relates to an input stage for an IR distance measuring system which works with modulated IR radiation, two radiation receivers (detectors) connected in antiparallel and working resistors and can be used for relatively large distance ranges. In the operating state, a signal in the form of a current difference is produced by the two radiation receivers and produces a voltage drop across a working resistor which is connected in parallel. This voltage drop is used as an output signal for subsequent processing in the distance measuring system. In the case of exact focusing, it is zero. <IMAGE>
