Title: Portable machine tool with shock protection - has insulation applied to handle in two layers of different colours to indicate danger when underlayer is exposed
Inventor: SPAETH UWE
IPC: H01B17/62
Filed: 1979-01-11
Abstract: The portable machine tool has safety insulation to protect the operator from shock and is intended to eliminate danger which may arise when thermoplastic insulation moulded onto the tool wears down without giving any indication of its loss of effectivenes. The insulation is applied in two layers of contrasting colours. The lower layer is typically red to indicate danger, and becomes visible when it has worn down to a level where the tool becomes dangerous. It can be applied to the handle of a screwdriver with a handle made of an aluminium alloy to achieve better adhesion to the insulation.

Title: Mfr. of dangerous chemical substances e.g. chlorine di:oxide soln. - by passing reactants through intercommunicating annular passages in reaction chamber, avoiding gas pockets
Inventor: CORBETT DENNIS THOMAS
IPC: B01J7/02
Filed: 1979-02-23
Abstract: Mfr. of a dangerous chemical substance consisting of a dangerous gas dissolved in a liq., e.g. ClO2 in water, comprises bringing the reactants from their respective sources at a predetermined rate to their respective inlets in a reaction chamber, where they flow through intercommunicating passages in the chamber so as to mix and react, and then flow out. The reaction chamber incorporates an instrument to measure the concn. of reaction prod. and a diluent feed, operated when the concn. exceeds a predetermined value. The inlets are near to one another to ensure early mixing. The reaction chamber is a vertical cylinder in which are coaxial tubes defining annular spaces. Intermediates spaces communicate at one end with the outer adjacent space and at the other end with the inner adjacent space. The passage bring about rigorous mixing and there are no large spaces where dangerous pockets of gas can accumulate. The plant is safe and reliable and allows a conc. soln. of a dangerous gas in a liq. to be made on a large scale without the need of a costly and space-consuming installation.

Title: Steel tube expander and calibrator - with polyurethane lined expander head segments
Inventor: BILLER THEODOR
IPC: B21C37/30
Filed: 1979-06-14
Abstract: Conventional expander heads cannot be used when steel tubes have to be expanded and calibrated which have a helical longitudinal welded seam, because the groove in the head is for straight seams and would have to be different for every tube size with helical seams. The segments of the expander head are lined therefore with a layer of elastomer material, vulcanized to steel sheets, to a thickness of two to five-times the height of the internal weld bulge. The pref. material is a polyurethane elastomer of 70-100 Shore A hardness. Such an expander can be used to expand and calibrate tubes, independent of the pitch of the welded seams.

Title: Decontamination of liquid effluent esp. from medical sources - using mechanical, chemical and filtering steps without any biological treatment
Inventor: SCHULZ WERNER
IPC: G21F9/04
Filed: 1980-03-31
Abstract: Method of decontaminating radioactive liquid waste consists of separating in continuous flow, the radioactive substances by mechanical and also chemical physical purification. Pref. the mechanical purification stage consists of settlement and/or flotation in a separation plant or in a sieve and screen plant or through coarse filters such as gravel bed filters. Before the effluent enters the mechanical separation stage its value is raised to 9.5 or above. After mechanical separation, the effluent may pass to a precipitation unit in which precipitating agents, especially hydrolysing salts and salt solutions are used,e.g. Fe-Al compounds, silicates, carbons and similar substances. Before entering this stage, the pH value may again be checked and adjusted. Used for the continuous treatment of radioactively contaminated liquid effluent, particularly that from hospitals. The treatment procedure comprises no biological purification whatever, on account of the probable presence of disinfectants and antibiotics in the effluent which tend to counteract biological treatment.

Patent DE-3023526-A1 (DE)
Inventor: ROEHRIG KLAUS
IPC: B65B13/06
Filed: 1980-06-24
Abstract: In an apparatus for girding packages with endless synthetic-resin strips, an assembly for bonding the ends of a web segment to one another comprises a press in the form of a fixed surface and a spring-loaded press bar shiftably mounted in a rotating truncated drum along a diameter thereof. An outer tangentially extending surface of the bar has a rotation path interrupted by the fixed surface. The drum also carries a blade forming one side of a wedge-shaped channel for guiding a trailing web-segment end during a bonding phase of an operating cycle. Upon the beginning of the bonding phase a leading web portion surrounds the package and traverses the drum channel. The rotation of the drum causes the press bar to clamp the web to the fixed surface, whereupon the blade cuts the web and produces a web segment having a trailing end. A heating mandrel pivoted into a wedge-shaped space between a leading web-segment end and the fixed surface on one side and the trailing web-segment end and the press bar on the other side slips over a surface of the trailing web-segment and, while being pushed towards a rest position by the rotating press bar. The press bar squeezes the heated segment end to the other end in a sweeping motion.

Title: Water level and wave meter eliminates spurious echoes - using sea-bed press. measurements if echo sounding path is disturbed
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: G01F23/296
Filed: 1980-07-16
Abstract: The meter is mounted in a carrier near the seabed. The results of the two types of measurement are evaluated together so that the spurions echos obtained during sounding with relatively large wave heights can be eliminated using the press. and press. fluctuation damping at relatively low wave heights. The press. measurement controls a variable depth aperture via the static water press. and the echo sounding system press. variations. This results in the evaluation of only those echos from the water surface. The logic passes the sounding measurements to the analyser if the echo sounding path is undisturbed, otherwise it passes the press. measurements.
