Title: Leaning tower straightening system - involves drilling boreholes under high side to promote sinkage to correct lean
IPC: E02D35/00
Filed: 1990-01-11
Abstract: The system is for the straightening of a leaning tower, e.g. leaning tower of Piza. A number of boreholes (12,24) (approx.  5cm diameter), extending in the direction of inclination of the building, are created on several levels below the foundations, in a sequence, beginning with the lower ones. The boreholes are placed on part sections of the vertical projection surface of the building. Ditches may be dug on up to three sides of the foundations. The auger for drilling the holes is located in an auxiliary shaft beside the building. USE/ADVANTAGE - Ground removed by boreholes, permits building to sink on higher side, thus straightening leaning tower.
Patent DE-4005281-A1 (DE)
Title: Paper-making stock inlet - has diluting water for suspension by segments, to control paper weight profile without altering stock inlet lips
Inventor: SCHULTZ HANS-JOACHIM DR ING
IPC: D21F1/02
Filed: 1990-02-20
Abstract: The stock inlet for a papermaking machine has a separate distributor for dilution water in a controlled feed near the fibre suspension. This gives local variation of the suspension concentration to control the lateral profile of the paper weight.  Turbulence tubes mix the diluting water with the suspension, and the dosed portions of the suspension are delivered to segments of the stock inlet. A feed channel is pref. provided for each stock inlet segment, and the turbulence tubes give stock inlet sections of 50-500 mm wide. The distribution width is determined according to the required accuracy of the lateral profile. The paper weight cross section is cotnrolled by a closed control circuit to regulate the dilution water in a direct injection, to give an even profile with a constant suspension flow. The stock inlet lips are constant, and can be stiffened to give a constant gap across the machine width and prevent paper structure variations. Parts of the stock inlet can be charged solely with water, to prevent paper being formed to give a narrow web width. ADVANTAGE - The system controls the paper weight profile, without altering the paper structure which can happen by adjusting the lips of the stock inlet.

Patent DE-4028081-A1 (DE)
Inventor: KOHL WALTER
IPC: F24H1/14
Filed: 1990-09-05
Abstract: In water heaters of the type described in the claim, the special steel end plates are made up of two plate parts rigidly secured together so that the weld seams of the water chambers (18) must be arranged in laterally staggered array to the end strips (26) of the end plates so that they can be reached by the welding device. The insertion of the end plate parts (30, 50, 60) of the invention makes it possible to attach the edge strips (26, 28) after the water chambers have been made so that they can be taken closer to the plate block of the heat exchanger and the latter can be shortened, thus reducing costs. The preferred field of use is in gas-fired water heaters for hot water supplies and central heating.
Patent DE-4029268-A1 (DE)
Inventor: KARNER JOHANN DR
IPC: C23C16/44
Filed: 1990-09-14
Abstract: The invention relates to a process and an apparatus for reactively treating the surface of a workpiece, in which a working gas is introduced into a bell jar and a direct-voltage arc discharge is generated in the latter; the arc discharge is assisted or maintained by injecting a current of charged particles. The plasma generated in the direct-voltage arc is generally inhomogeneously distributed in the interior of the bell jar in known processes and the region having an adequate plasma density for reactive surface treatment is relatively small. According to the invention, this problem is solved by fixing the distribution of the treatment action of the plasma in the bell jar at least over a specified area, in particular by establishing a two-dimensional distribution of the working gas injection and/or by establishing a two-dimensional distribution of the arc discharges in the bell jar by injecting the current of charged particles via a plurality of distribution openings. In this way, spatially extended plasmas having high ionisation densities and acceptable energy densities can be produced, with the result that, on the one hand, treatments of large surface regions can be carried out and, on the other hand, treatment processes can also be carried out on thermally sensitive objects.

Title: Device for preventing loosening of musical instrument strings - by preventing rotation of wrest pin
Inventor: HEBBORN THOMAS
IPC: G10D3/14
Filed: 1990-10-25
Abstract: A stringed musical instrument has wrest pins around which the ends of the strings are wound. The wrest pin is then rotated in order to apply the required tension to the string. Each wrest pin is prevented from rotating so that the string becomes loose by means of a spring ring (1). The ring has a longitudinal slot to provide the required spring characteristic. The bore of the ring in its free state is slightly less than the diameter of the wrest pin so that when in place the wrest pin is firmly gripped. The ring is prevented from rotating by a pin (3) fitted in a tangential groove with the free end of the pin abutting against an adjoining ring. USE/ADVANTAGE - Preventing the loosening of instrument strings by a simple device which does not require screws.

Patent DE-4038057-A1 (DE)
Inventor: KERZ LUDO DIPL ING
IPC: H04N1/405
Filed: 1990-11-29
Abstract: The object of the invention is a process for generating and storing digitised density thresholds for defining the grid of a half-tone image. The density thresholds of a section of a grid are stored in a data store as stored words depending on a spot function. In the grid section, several spots with a number of stored words form a multiple grid spot and are periodically arranged beside and above one another. A sorted sequence is found for the stored words of the section in accordance with the spot function. Density thresholds are allocated to the stored words depending on the position in the sorted sequence. The actual number of stored words is found individually for each spot in the section. The sorted sequence is generated according to the current spot function. Before position-dependent thresholds are allocated to the stored words, a centre of concentration and possibly final point correction is performed for the spot concerned.
