Title: Stack memory arrangement giving reduced access time - has switchable register blocks between stack memory and CPU
Inventor: NAGEL KLAUS DR
IPC: G06F5/16
Filed: 1989-04-28
Abstract: At least two blocks of registers (RG1,RG2) arranged between the stack memory (STP) and a data processing unit or CPU (CPU) can each be connected via switches to the stack memory or CPU.  A stack pointer points to the registers of a block being accessed by the CPU.

Title: Arcing unit for overload protection - has two part arc paths in series to provide protection
Inventor: HASSE PETER DR ING
IPC: H01T4/16
Filed: 1989-05-03
Abstract: A double arc path is provided by three electrodes (1, 2, 3) that are separated by layers of insulating material (4, 5). The arc paths (F1, F2) are formed across the insulation and as such are coupled in series. The cross section of the assembly is circular and so forms a disc electrode system. The top arc path section (F1) is stepped and this provides a capacity that exceeds that of the lower one (F2). Arcing occurs when the voltage between terminals (6, 7) exceeds a set threshold value. ADVANTAGE - Simple means of providing overload arc path.

Title: Locking device for drawers
Inventor: GIARETTA MICHELANGELO
IPC: E05B65/465
Filed: 1989-05-24
Abstract: The invention is intended to make available a device which, in a chest of drawers, when a single drawer is opened, locks all the other drawers. For this purpose, the device has a vertically arranged rod (8) which is mounted on the housing (9) of the chest (1) such that it can pivot about a vertical axis. Interacting with said rod (8) are plate-type elements (4), of which in each case one is fastened on each drawer (2). The rod (8) engages into all the slits (5), comprising two rectilinear portions (6, 7) which form an acute angle with one another. When one drawer (2) is opened, the rod (8) is pivoted, by way of the portion (6), which runs obliquely with respect to the opening direction, of the slit (5) of said drawer (2), into the portion (7), running transversely with respect to the opening direction, of the plates (4) of the other drawers (2), as a result of which said other drawers are locked in their closed position. <IMAGE>
Patent DE-3922376-A1 (DE)
Inventor: BERGNER ARNDT
IPC: B28D1/14
Filed: 1989-07-07
Abstract: A device, for cutting an undercut in a borehole at a location spaced from the surface of a material into which the borehole is formed, includes a housing (1) with a bore therethrough and a guide sleeve (2) rotatably supported in the housing bore and having an eccentric bore therein. A bushing (3) with an eccentric bore is rotatably supported in the guide sleeve bore. A drive shaft (7) is rotatably supported in and extends through the eccentric bore of the housing and has a cutter head (9) at one end. The drive shaft (7) can be shifted from a centered position within the housing bore into an eccentric position by rotation of the bushing (3) relative to the guide sleeve (2). In the eccentric position, the cutter head (9) can penetrate into and form an undercut in the surface of the borehole. A displacable snap-in element (16) in the housing (1) prevents rotation of the guide sleeve (2). When the maximum eccentricity of the drive shaft (7) is reached, the snap-in element is disengaged from the guide sleeve by an actuating cam (3a) on the bushing (3). Subsequently, the guide sleeve (2) and the bushing (3) can be rotated together through at least 360 DEG  degrees for cutting the undercut. A blocking member (13) prevents rotation of the guide sleeve (2) during rotation of the bushing back into the center position.

Title: Interference suppressing circuit for video signals - has output video signal delay and subtractor for delayed signal from input video signal to form differential signal
Inventor: OZAKI HIDETOSHI
IPC: H04N5/21
Filed: 1990-03-14
Abstract: The circuit processes an input video signal into a corresponding output signal with considerably suppressed input signal interference components.

Title: Paper-making drying section in paper making machine - has compressed air directed at free side of the web in a free path to reduce shrinkage unevenness
Inventor: STEINER KARL DR
IPC: F26B21/00
Filed: 1990-04-19
Abstract: In the drying section of a papermaking machine, compressed air is directed at the free side of the paper web, at least in the straight and free path between neighbouring drying cylinders. Compressed air is applied also to the curved free path of the web, at its free side. The air is applied to the free side of the web from the start to the end of the straight and curved paths where the web travels freely, to act only on the edge zones. At least one blowing chamber is at the web path. A sealing is between each drying cylinder where its mantle surface is in contact with the web and the associated blowing chamber, using a scraper or brush or a blown air stream. When using a scraper and a blown air stream, the air from the jets passes almost parallel to the scraper blade and along its length to blow into the gap between the cylinder and the web. The drying cylinder not in contact with the web has a groove surface and it is a suction roller. The cylinder in contact with the web has a closed mantle surface. ADVANTAGE - Inconsistent shrinking is reduced or eliminated in the web, esp. laterally across the web line.
Patent DE-4013317-A1 (DE)
Inventor: EHRLICH WOLFGANG DIPL ING
IPC: H04J3/07
Filed: 1990-04-26
Abstract: When an asynchronous digital signal is to be introcuced into another digital signal, there arises the fundamental problem of frequency adaptation. This problem is solved by stuffing. Another problem found with the usual suffing process is that the digital signal recovered by destuffing is affected by a low frequency jitter, the waiting time jitter. This waiting time jitter must be reduced. A stuffing process is disclosed which includes within each stuffing frame of the initial digital signal (B) the following steps. The mean level of the elastic memory (ES) is determined as precisely as possible. A difference between the real value and the prescribed value of the mean level, the level error (ff), is determined. The level errors are added and form the error sum (fs). The decision whether to stuff is made on the basis of the criteria that the error sum must be kept as constant as possible. For this purpose, an assessed value is calculated for the error sum in the following stuffing frame of the second digital signal (B) on the supposition that no stuffing will be carried out. This assessed value (fs + 2ff) is compared with thresholds and a value that indicates whether and to what extent stuffing will be carried out is determined on that basis. The invention relates to multiplexers and synchronizers.

The layout has a field lens in the path of the beam either before or after the reflecting surface. A group of objectives is located in front of the optical receiver; an image of the surface is produced in the aperture plane of that group, and an image of the light source is produced on the optical receiver. ADVANTAGE - Produces three-dimensional picture which enables surface finish to be surveyed and its structure to be evaluated.
