Title: Fluid control valve with multi-point travel - has two-stage movement of valve spindle in concentric tube, each having own piston and stops
Inventor: DAUME BRITTA
IPC: F16K31/122
Filed: 1989-10-05
Abstract: In processes such as filling and weighing a fluid control valve is needed with definite intermediate positions between fully open and shut. In the invention a multi-point fluid control valve has two spring loaded pistons (K1, K2) of different diameters. The larger piston is fastened to the top of spindle (S) which has throttle valve (DK) at the bottom end. The spindle can slide up and down inside a tube which itself can be moved up and down by forces acting on the smaller piston. The linear movements of the spindle and tube are limited by adjustable stops (A1, A2, A3). Controlling air or oil admitted to control inlets E1, and E2 allow the spindle and throttle valve to be moved to definite, adjustable end and intermediate positions. ADVANTAGE - Fully adjustable. Simple, low-cost design.
Patent DE-3938755-A1 (DE)
Inventor: SAALMANN GUENTHER
IPC: A47L15/44
Filed: 1989-11-23
Abstract: The invention concerns the continuous cleaning of utility crockery in a commercial dish-washing machine with a washing zone and a subsequent rinsing zone, an increased cleaning-agent concentration being used in at least some areas in the washing liquor. The aim of the invention is to increase cleaning performance without increasing overall cleaning-agent consumption and without the need for very highly concentrated cleaning-agent solutions. This aim is achieved by the process of the invention by virtue of the fact that a major part of the washing-solution flow is taken from the last tank and fed directly into the third from last tank and/or a tank further upstream, the amount taken being more than 50 %, preferably more than 75 %, of the amount of fresh water running into the last tank. The remaining washing solution is passed through the tanks, at least from the middle and/or penultimate tank on, in cascade. In at least the middle and/or penultimate tank, the cleaning-agent concentration in the washing solution is increased by at the most the same factor as the ratio of the fresh-water flow to the remaining washing-solution flow, the addition of cleaning agent being made into this/these tank(s) only.

Title: Word length limiting of carry save numbers - bits combined in exclusive or circuitry
Inventor: NOLL TOBIAS G DIPL ING
IPC: G06F7/50
Filed: 1990-02-13
Abstract: A digital process is used to limit the word length of carry save values involved in the two's complement processing of binary numbers. The process employs the sum values (S) and the carry values (c) of `n' bit binary words. The bits are received by exclusive-OR gates (E1-E3) that generate the word length limiting action using a reduction process. The sum bits (Sn-1, Sn-k+1) and the carry bits ((n-1) (n-k+1) are no longer required. ADVANTAGE - Limits word length of carry save numbers.

Inventor: SCHLITTENBAUER FRANZ
IPC: B63B35/79
Filed: 1990-03-16
Abstract: A fastening clamp for trapezoidal rope ends which is mounted on the wishbone of a wind surf rig consists essentially of a clasp-type shell (2) and a double-membered buckle (16) which can be unhinged on one side. If the open shell is preloaded, the buckle cannot be unhinged without human intervention. This ensures in a simple manner that the fastening clamp can slide on the wishbone tube (4) when the buckle is open without the risk of becoming detached from the wishbone tube. The fastening clamp can be manipulated with one hand.

Title: Deep colouring of natural stone - by applying a mixt. of colourant, toluene@ or xylene, and oil, and soaking into stone
Inventor: SCHOEPFEL THEODOR
IPC: F02B3/06
Filed: 1990-11-28
Abstract: Deep colouration of natural stone, particularly limestone such as lithographic stone or Jura marble. A mixture of at least one colourant, and aromatic hydrocarbon such as toluene or xylene, and an oil, is applied to the stone and allowed to soak in. The colourant is mixed with toluene, and this mixture is then mixed with oil. The mixture is applied by means of a soaked, absorbent support, e.g. a rag. The intensity of colouration can be altered by varying the toluene content. The stone may be heated before applying the colorant mixture. The mixture may be applied to the naturally or artificially roughened surface of the stone, followed by polishing. The oil used is a synthetic or vegetable oil, e.g. cooking oil, soya oil, rape oil, diesel oil, liquid paraffin, etc. The mixture has a fluid, brushable or sprayable consistency. USE/ADVANTAGE - The process imparts colour to the stone in a way which does not detract from its natural texture (unlike paint). The colour is durable, and decorative, and can be produced on natural stone objects or buildings
