Title: Device for paper, foil etc. intermittent feed - uses upstream and downstream rollers moved by active tool stroke to relax web to be fed
IPC: B41F19/00
Filed: 1980-09-03
Abstract: The mechanism is intended for carrying out a pressing, embossing etc. operation on intermittently fed paper, foil or the like material (3) by a tool (7) which reciprocates in a direction at right angles to the intermittent feed direction. The material passes around rollers (5) upstream and downstream of the tool, which are moved by the active stroke of the tool. This provides the slack needed for the material to follow the tool movement, whilst maintaining controlled tension. The rollers may be held in carriers (15) which are each movable in a fixed bush (16) and provided with a cam roller (14) following a cam slot (13) in a plate (12) fixed to the tool.

Title: Iso:alkene prodn. from N-alkene(s) - by isomerisation with fluorinated alumina catalyst in presence of water
Inventor: FRANZ GERHARD DR
IPC: B01J21/20
Filed: 1980-10-29
Abstract: Isomerisation of n-alkenes (I) to isoalkenes (II) is effected at 250-550 deg.C using a fluorinated alumina catalyst, with the improvement that (i) the reaction is effected in the presence of 0.5-150 (pref. 2-130)wt.% water, based on the wt. of (I); (ii) fluorine lost from the catalyst is continuously or periodically replaced by means of a volatile F cpd. (esp. HF); and (iii) the catalyst is regenerated by burning off coke deposits with an O2-contg. gas in the presence of steam. The process is esp. useful for converting n-butenes to isobutene (IIa), which is an intermediate for methyl t.-butyl ether (fuel component) or methyl methacrylate. Addn. of water moderates the activity of the catalyst, giving increased selectivity for (II) and increased stability (longer time between regenerations).

Title: Optical tissue blood flow measurement system circuit - contains light source regulated according to tissue light transmission
Inventor: SONTOPSKI WILLI
IPC: A61B5/024
Filed: 1980-10-30
Abstract: The circuit for an optical system is for measurement of the blood flow through tissue (15) contg. an optical transmitter (1) and receiver (2). It has a current source (3) and an output for a pulsed output signal. The arrangement excludes differences in basic damping leading to output signal differences dependent on tissue quality and blood flow. The emission intensity of the transmitter (1) is regulated according to the light transmissivity of the tissue (15). The receiver is maintained at the optimum operating point at all times. The order of magnitude of a working resistor on the output (4) is chosen so that about half the operating voltage (UB) is dropped across this resistor. The voltage drop is regulated to be half the operating voltage by controlling the current source according to the output signal magnitude using feedback.

Title: Selective multiaxial three=phase drive for trolley-buses etc. - has wheel sets with individual drive of groups of series traction motors, controlled w.r.t. driving conditions
Inventor: HUSSEL REINMAR ING GRAD
IPC: B60L15/20
Filed: 1980-11-11
Abstract: The wheel sets of the trolley-bus are driven by several three- phase motors, coupled to a controllable inverter. The drive provides a speed equalisation of the driven wheels when driving round curves. The wheel sets are fitted with individual wheel drive in such manner that in each case at least one group of two series-connected motors (7-10) are used. One or several motors of one bus side are under speed control, responsive to the criteria of curve direction, drive, or braking operation. The motor(s) on the other side of the bus are freely adjusted by the natural motor characteristic. In normal drive operation through curves the outer motors operate at higher speeds than the inner motors on the other bus side. During braking operation under the same conditions the speed of the inner motors is controlled, while that of the outer motors is left without control arrangement.

Patent DE-3108435-A1 (DE)
Inventor: PIGUET CHRISTIAN
IPC: G06F3/048
Filed: 1981-03-06
Abstract: A device is provided for the rapid and easy introduction of data into an apparatus, e.g., for setting a digital watch. A binary decision device continuously tests the state of a plurality of finger responsive sensors A, B, C and D and produces control signals for a operational unit. The operational unit comprises an up-down counter which can be incremented or decremented by signal F1 to F8 at different frequencies. An inertia effect is produced by maintaining counting of the up-down counter between two successive actuations of the sensors. Touching sensor B or C stops the counter. Sweeping A, B, C, D speeds the incrementing rate (up to a top rate) or slows the decrementing rate while sweeping D, C, B, A acts conversely. Touching A and D alone, respectively, single-steps the counter down and up. The amount by which the rate is speeded or slowed can be made to depend on the speed of sweeping the sensors as well as the number of times they are swept. Other embodiments use three buttons A (speed up), B (slow down) and C (stop). Pushing A+C single-steps the counter up while pushing B+C single-steps the counter down. The amount by which the rate is speeded or slowed can depend on the number of operations of A or B or also on the length of time A or B is held depressed.

Title: Process for artefact reduction in layer images
Inventor: KLOTZ ERHARD ING GRAD
IPC: G03C5/08
Filed: 1981-11-19
Abstract: Layer images, in particular those produced by synthetic tomography, frequently show artefacts in the form of fine filigree structures, which do not originate from the actual layer. According to the invention these artefacts are eliminated by producing from a primary layer image a central copy and also multiple copies situated at a finite distance therefrom. By this means the artefacts described are substantially suppressed, while the structures contained in the object layer to be copied do sharply decrease in contrast, but are still sufficiently clear. <IMAGE>

Title: Method and apparatus for the manufacture of gearwheels
Inventor: GROB BURKHART DIPL ING
IPC: B21K1/30
Filed: 1981-12-12
Abstract: In the new method, the stamp (4, 5) acts from both sides on the blank for the gearwheel (2), which is mounted on the dividing apparatus (11). By means of the indexing mechanism (3), the gearwheel is turned by one tooth after each stroke. Hammering is performed in a rapid sequence and the depth of the stroke is increased continuously by means of the adjusting devices (8). The stamps (4, 5) are matched to the shape of the tooth and hammer in the tooth gap, while the displaced material rises and forms the tooth. In particular, there are limit stops on the stamp which ensure that the material does not escape at the side. In this way, it is possible to manufacture high-quality gearwheels without cutting. <IMAGE>

Title: Method for reducing the twelve-fold uncertainty of the carrier phase of a 16-QAM signal at the receiving end
Inventor: BESSAI HORST DIPL ING
IPC: H04L27/38
Filed: 1981-12-23
Abstract: The invention is intended to reduce this uncertainty to only a four-fold uncertainty. For this purpose, a known phase-locked loop having a first frequency quadrupling stage (1) in the input and a second frequency quadrupling stage (2) in the feedback loop is used. The highest of the three amplitude steps occurring in the envelope curve of the 16-QAM signal is overproportionally amplified in the first frequency quadrupling stage (1). This results in a locking-in of the phase-locked loop at one of the four phase angles 45 DEG , 135 DEG , 225 DEG or 316 DEG . The overproportional amplification of the highest amplitude step is produced by utilising the characteristic of the first frequency quadrupling stage (1). In this arrangement, the highest amplitude step is amplified by about 6 dB in voltage compared with the middle amplitude step. <IMAGE>

Title: Bolting for roadway support frames
Inventor: MENNEKES WERNER
IPC: E21D11/28
Filed: 1982-01-07
Abstract: It is know to secure spacers, serving as bolting for two adjacent roadway support frames, merely to a profiled lug by means of hook bolts. For this purpose, the spacers must be adapted to the respective course of the roadway. The miner must thus ensure that the spacers are also fitted at the correct location in the course of the roadway. The measure according to the invention now uses spacers (5) consisting of a centre longitudinal section (6) and two end positive-locking bodies (8), the end faces (11-14) of which are adapted in a positive-locking manner to the outer contour (15-18) of the channel-section segments (1) in the area of the profiled lugs (4). Thus it is possible to not only satisfactorily secure the positive-locking bodies (8) to only one profiled lug (4) in a two-dimensional manner by means of the hook bolts (9) but also, through the articulated connection with a centre part (6), to create the preconditions for only one type of spacer (5) to be necessary. <IMAGE>

Title: Double sleeve for connecting two pipes having smooth-cylindrical ends
IPC: F16L25/14
Filed: 1982-01-30
Abstract: The invention relates to a double sleeve (3) for connecting two pipes (1, 2) having smooth-cylindrical ends and different external diameters (D1A and D1B). The sealing of the pipes (1, 2) in the double sleeve (3) takes place by means of roll-sealing rings (9A and 9B) which are pressed into the double sleeve when the pipes are pushed in. In the case of such known double sleeves, the sleeve halves are identical so that only pipes having the same external diameter can be connected in a sealed manner in such a double sleeve. In order also to be able to connect pipes having different external diameters, the invention proposes that the internal diameter of the sleeve inputs, of the preparation spaces (6A, 6B), of the compression collars (7A, 7B), of the sealing ring spaces (8A, 8B), of the stops (10, 11) and of the roll-sealing rings (9A, 9B) in the sleeve halves (5, 4) be constructed of a suitably different size and that the stop (10) in the sleeve half (5) having the greater unobstructed width be provided at least predominantly on a radial wall (13) which connects the two sleeve halves (4, 5) at least over the majority of their circumference. The main application of the invention is in the connection of drainpipes in buildings. <IMAGE>
