Title: Data error recognition system - raises recognition rate by dividing by polynomial and using remainder as transmitted data check
Inventor: ECKERT KLAUS DIPL ING
IPC: H03M13/15
Filed: 1974-02-21
Abstract: The error recognition system for data transmission systems divides the data about to be transmitted and data that has been transmitted by a polynomial function, and uses the remainder left after this division has occurred at the transmitter as test or check information tacked onto the end of the words. At the receiver this test or check information is first inverted and divided at the end of the transmitted words by the polynomial. The remainder left after this division is then used as a criteria for the correctness of the transmitted words. No circuit alterations are necessary at the transmitting station while only minor ones are necessary for existing equipment at the receiving end.

Title: Plug connector for printed cct board - has two-layer stamped resilient contact strips in one piece with crimped terminals
Inventor: BISCHKOPF HERMANN
IPC: H01R13/115
Filed: 1974-04-10
Abstract: The plug connector with spring-loaded stamped contact strips is intended for connecting to the strip tracks on printed circuit boards. The spring-loaded prongs of the contact and the crimping terminal section are all made in one piece. The resilient contact strips are produced from a thin metal sheet and then folded to the desired shape in three stages. The double pair of prongs is fist cut out and folded over to produce the spring-laoded contact jaws. This is done along an edge cut through the centre of the material of the prongs. The free ends are folded inwards to produce double walled jaws. The tail end is then bent through a right angle and is crimped around the wire end.

Title: Liquid contamination measuring instrument - with liquid filtered through a layer of several sheets of filter paper
Inventor: WADA YONEJI
IPC: G01N33/28
Filed: 1974-04-18
Abstract: Contaminants from the top and bottom filter paper are compared with each other. A number of filter papers are used, whose pore size is greatest at the top, and smallest at the bottom, and contaminants on different filter papers are compared for concentration and particle size. The device realising this method consists of a filter and a vessel taking a certain amount of contaminated liquid and a layer of several sheets of filter paper. The measuring device with a source of light of specified wavelength is for illumination of the top and bottom filter paper sheets taken out from the filter. It is reflected from the top or bottom filter paper received by a photoelectric transducer whose output signal depends on quantity of contamination deposited on the filter paper. A bridge circuit compares the signals and delivers a difference output signal in accordance with the liquid degree of contamination.

Title: Lifting apparatus side thrust mechanism - has forks slewing on vertical axes between opposite positions
Inventor: MEYER HANS H
IPC: B66F9/14
Filed: 1974-05-27
Abstract: The mechanism is particularly for forklift trucks, where the forks can be pointed to either side from the slide. Each fork prong (10, 11) slews about a vertical axis (8, 9) between two working positions 180 deg. apart.

Title: Hydraulic piston seal with wedge shaped support ring - prevents seal ring extrusion by eliminating radial gaps
Inventor: DIETRICH GEORG DR ING
IPC: F16J15/16
Filed: 1974-07-09
Abstract: The piston (4) of a hydraulic cylinder (6) carries a seal ring (1) in a circular groove (3). A wedge shaped support ring (2) of triangular cross section is placed next to the seal ring so that the inclined side of the support ring (2) is in contact with a matching incline on the groove wall. The fluid pressure on the seal ring (1) forces the support ring radially outwards due to the inclined faces. The pointed inner edge (7) of the support ring prevents the formation of a gap along the base of the groove. In this way, seal ring extrusion and thus its destruction is avoided.

Patent DE-2446780-A1 (DE)
Title: Method of damping valve noise - uses layers of balls in cylindrical cages surrounding valve seat
Inventor: WOLZ WERNER DR
IPC: F16K47/08
Filed: 1974-10-01
Abstract: The valve seat is attached to a central tube connected to a top plate. The valve head slides within the central tube and when the valve is fully open the perforations are fully exposed to the fluid flow. The central tube is surrounded by a larger perforated cylinder and the annular space between tube and cylinder is filled with layers of balls separated by a series of flat plates. The noise damping can be controlled by varying the resistance offered by the valve to the fluid flowing through it. The resistance can be varied by raising or lowering the valve head to expose varying numbers of layers of the balls.

Title: Ski attachment for assistance in hill climbing - supports skiers foot at angle to ski to suit slope and consists of simple wedge of plastics
Inventor: STEINBEISS PETER
IPC: A63C9/00
Filed: 1974-11-20
Abstract: Ski boots are usually attached to skis so that the sole lies parallel to the ski surface. When climbing to the top of a ski slope this method of attachment imposes a strain on the legs as the skis align themselves to the hill slope. The invention overcomes this difficulty by the use of a wedge of plastic placed between the ski and the sole of the ski-boot so that the sole is horizontal when the ski is aligned with the hill slope. The vertex of the wedge is under the toe of the boot and the wedge may be an integral part of the ski fixing.

Title: Erection of elevated shelving stacker - involves matching installation to the shelving floor and the operating equipment
Inventor: JUERGENS WALTER DR ING
IPC: B65G1/02
Filed: 1975-05-27
Abstract: The shelving installations are operated by elevated stackers and usually require the floor to be true. This requirement demands high expenditure in the case of new constructions. In existing buildings the inaccuracy is greater, and the shelving installation is placed in conformity with the weighing machine and the gangways are equalised later. In order to overcome this problem, the normal procedure is reversed and the shelving is matched to the floor, so that the shelving gangway is the starting point for the assembly of laterally standing shelving. In this way the floor, shelving and equipment are in their optimum relative positions.
Patent DE-2532010-A1 (DE)
Title: Greasing pivot for windscreen washer stub - with slotted spacer washer to ensure even supply of grease
Inventor: POKOLM ERICH
IPC: B60S1/34
Filed: 1975-07-17
Abstract: The windscreen wiper stub is secured axially in the bearing by a circlip in a groove in the stub shaft. The clip (15) lies against a spacer ring (17) fitted inside the bearing, with the whole bearing covered by a nut complete wiht greasing nipple. To provide even greasing, the spacer ring has slots (16) on the inside diameter. The slots ensure that the grease flow reaches all parts of the bearing no matter in what position the circlip is set relative to the spacer ring. The wiper is thus protected against ingress of water and dirt and is easily removed for repair.

Title: Pure alkali phosphate prodn. from crude phosphoric acid - by extn. with organic solvent and treatment with alkaline cpds.
Inventor: CHERDRON EGON DIPL CHEM DR
IPC: C01B25/46
Filed: 1975-08-30
Abstract: Pure alkali phosphates are produced from crude phosphoric acid by treating with an organic solvent capable of dissolving >=9 wt. % of water; sepg. the organic phase; treating with alkaline cpds. whereby an aq. and an organic phase are formed; and adding more alkaline cpds. to extract the corresp. mono-, di- or tri-orthophosphates into the aq. phase. The process is improved in that phosphoric acid (which can be preliminarily purified) and an organic solvent are mixed together, whilsts alkali- and/or ammonium ions are pref. added. The organic phase is passed through a series of extractors in countercurrent to an aq. phase contg. alkali- and/or ammonium ions. The resulting organic phase contg. pure H3PO4 and water is treated with alkali- or ammonium salts, oxides or hydroxide, whereby this phase is divided into an aq. phase contg. mono-, di- or tri-orthophosphates and pure organic solvent. Sulphuric acid can be added to free H2PO4; sulphuric acid is subsequently pptd. by treatment with a calcium cpd., esp. a crude phosphate. High-purity alkali phosphates can be produced.
