Patent DE-2825816-A1 (DE)
Title: Magnesium bi:sulphite mfr. with low chloride content - obtd. from waste combustion gases produced in a lye boiler
Inventor: LOQUENZ HEINZ DIPL ING
IPC: D21C11/06
Filed: 1978-06-13
Abstract: The combustion gases are fed through a chemical recovery plant using a dry separator removing part of the MgO in the gas, followed by a wet scrubber in which the residual MgO and SO2 in the gas form magnesium bisuplhate (I) which enters the wash liq. together with chlorides. Wash liq. is heated so the (I) forms SO2 and magnesium sulphite (II) which is pptd. followed by removing part of the liq. contg. chloride. The gas leaving the scrubber enters other scrubbers to form (I). Wash liq. pref. also contains suspended (II), steam being used to form more (II) and SO2; the SO2 is pref. used in the succeeding scrubbers producing (I). Chlorides are removed from the (I) without losing large amt. of chemicals.

Title: Tyre grinding machine to remove high spots - has infeed control system using braking effect on grinding wheel for control
Inventor: KIESL MICHAEL
IPC: B24B49/16
Filed: 1978-07-04
Abstract: The grinding machine for truing tyres has a frame (10) on which a rim (12) is mounted.

Title: High pressure reciprocating plunger pump - has floating sleeves round plunger to form seal imposing low hydraulic forces on cylinder
Inventor: MAASBERG WOLFGANG
IPC: F04B53/16
Filed: 1978-10-24
Abstract: The pump has a plunger which is carried through a thin wall cylinder (4). A series of sealing sleeves (6) is fitted round the plunger between it and the cylinder. The pressure falls along a small gap (2) between the plunger and the sleeves and forms the seal. Each sleeve is sealed to the cylinder wall by O-rings (7, 12) at its axial ends. Radial holes (13) at its lower end admit liquid at the lower end pressure to the back of the sleeve. As the working pressure rises, the sleeves deform conically (15) and the pressure on the cylinder is kept down so that it can have a thin wall.

Title: Anode protection cup - with elastomer suction cup and central boss surrounded by undercut on base
Inventor: FROEHLICH GEORG DIPL ING
IPC: H01J9/00
Filed: 1978-11-09
Abstract: An anode protective cover to save the anode bushes in TV cathode ray tubes from attack when the tubes are processed by HF consists of a suction cup, pref. made of an elastomer (rubber) and in one piece. A boss lies in the centre with a flat bottom and with an undercut at its base having a sharp edge. The axial distance of the sealing lip from the bottom of the suction cup is made greater than the distance of the sharp edge. The result is that enough pressure has to be applied to shift the edge across the undercut, so that a secure hold is ensured. The central boss helps to centre the bush.

Title: Housing for pressure and temp. instrument fitted to panel - has projecting hooks with heads engaging in holes with locating pins
Inventor: BAADER HELMUT DIPL PHYS DR
IPC: H05K5/02
Filed: 1979-02-06
Abstract: A housing is for a pressure or temp. monitoring instrument which is attached to a panel of a domestic appliance such as a washing machine. The housing is made with projections which are fitted in holes on a panel with a support surface. The housing does not require any separate fixing elements and can therefore be mounted under different conditions, such as differences in dimensions of the components to be joined. The joint is rigid and free of any vibrations. Two of the projections are made as spring-loaded hooks (38) along the side of the monitoring instruments and allow adjustment for different distances between the holes (42) in the support panel (12). The hook is made with a locking head which clamps against the remote surface of the panel. The housing is also fitted with a pair of centering pins (34) between the hooks which engage in two locating holes. There is an additional spring for shock absorption.
Patent DE-2905751-A1 (DE)
Inventor: BUESSEM RUDOLF DIPL PHYS
IPC: E03C1/10
Filed: 1979-02-15
Abstract: In this automatically controllable shut-off device, for the purpose of preventing backflow of contaminated water into the water-supply system channelling, in particular, drinking water, the water-supply line can be connected to a separation line (14) via a main valve (13) forming a first shut-off valve. The separation line (14) is connected to a backflow preventer (15), the outlet of which is used as the connection of the water-consumption system (11). A second shut-off valve (20) is assigned to the separation line (14) in order to empty the latter. The invention further provides an actuating device (30, 43, 37) which is used to activate the main valve (13) and the second shut-off valve (20) in opposite directions and can be controlled in dependence on the pressure in a line of the water-consumption system, such that, when water is not withdrawn from the main water-consumption line (23), said actuating device shuts off the main valve (13) and opens the second shut-off valve (20) and, when there is a change of pressure in the main water-consumption line caused by water consumption, the actuating device switches said two valves into their other positions. This shut-off device ensures a reliable, hygienic and physical separation of the water-supply line from the water-consumption system, can be produced in a cost-effective manner and is particularly suitable for stationary fire-extinguishing systems, such as sprinkler systems. <IMAGE>

Filed: 1979-06-09
Abstract: The retaining clip (2) has a fastening web (3) and two legs (4, 5) which are angled off at an angle of 45 DEG  with respect to the pipe clamp. A carrying angle, the legs (8, 9) of which run parallel to the legs (4, 5) of the retaining clip, is fixedly connected to the pipe clamp. On both sides of the legs (4, 5) there are located damping bodies (6, 6') which are clamped in between the carrying-angle legs (8, 9) and a pressure-applying plate (10, 11). Each pressure-applying plate (10, 11) is connected, via at least one clinch bolt (20, 21), to the associated leg (8 or 9, respectively) of the carrying angle. Openings, which surround the clinch bolts (20, 21) at a distance, are provided in the legs (4, 5) of the retaining clip (2), and preferably also in the damping bodies (6, 6'). By means of this design, the intention is to prevent, even under large loadings, a displacement of the retaining-clip legs, clamped in by the damping bodies, relative to the legs of the carrying angle. <IMAGE>
