Title: Process to construct hawser - utilises plastic segments to hold steel wires to build up one section at a time
IPC: E01D19/16
Filed: 1989-10-31
Abstract: Hawser is constructed from steel wire with separators, firstly laid in segments and then built up into a complete circle. The steel wire (2) is made into a central core (3) or tube (3'). Each segment (5) is filled with more wire (2) into the sections (6) or (6'). The segment is larger than the 60 degree angle, so that the sides (7) will engage into the adjacent segments, which are made of plastics. A double gap (14) is left at the circumference. The inner part (9) matches the tube (3') or the built up core. The gaps in the wires will finally be set in cement and form an outer corrosion proofing (13). USE - The steel cable may be up to 25 metres long, as required for bridge building, or anchorage in construction work. The process can be carried out single handled.

Inventor: BERGER GUENTHER
IPC: B24B55/05
Filed: 1989-12-08
Abstract: The guard sector (1) is bent over on the inner edge to form a rim (3) which fits against the neck (6) of the portable grinder. A metal band (5) fits over the rim (3) and can be tightened around the neck by the screw (11) spanning the ends (7,9) of the band. The band is long enough to create a space (15) which can receive the short arm (17) of a bent lever (18) pivoted through a slot (24) in the band. When closed the lever tightens the band onto the neck (6). When the lever is lifted the band is loosened and the guard can be moved into the desired working position.

Title: Test kneader - determines preservation of polymer workability based on torque comparison
IPC: G01N11/14
Filed: 1990-03-18
Abstract: Polymers are tested for the preservation of their properties in test kneaders by a rheokinetic technique. Torque and temp. are recorded as a function of the time, starting from a reference instant which is empirically determined by the termination of melting/plasticising processes. The torque readings are converted to a reference temp. and the ratio of the torques at the time (t) to that of the reference time indicates the deg. to which the polymer has preserved its ADVANTAGE - Gives valuable data on changes in the workability of polymers due to thermal and mechanical stresses and on the effectiveness of fillers, stabilisers and reaction systems.

Patent DE-4021288-A1 (DE)
Inventor: SCHULZE GISBERT
IPC: C04B35/66
Filed: 1990-07-04
Abstract: To produce a ceramic silicate-based or alumina-based moulding, a ceramic starting product, which contains clay, kaolin, soapstone and/or alumina, is mixed with a silicate-containing flux, the mixture is moulded to give a moulding and the moulding is heated and dense-sintered. The flux used consists at least partially of a preferably alkali-free glass frit, which starts to soften above 850 DEG C. Advantageously, an alkali-free borosilicate glass is used in quantities of from 0.1 - 20% by weight of the starting mixture. By means of this process, ceramic mouldings can, inter alia, be produced which consist of a glass phase and a crystalline fraction essentially containing Al2O3, the proportion of the glass phase being 22-34% by weight and consisting of 50-68% by weight of SiO2, 12-22% of Al2O3, 0.1-4.5% of Fe2O3, 0.1-13% of TiO2, 0.1-23% of CaO, 0.1-9% of MgO, 0-7% of Na2O, 0-11% of K2O, 0-9% of BaO and 0-23% of B2O3, and the crystalline proportion consisting of 1-25% of SiO2, 70-80% of Al2O3, 0.1-1% of Fe2O3, 0.1-3% of TiO2, 0.1-5% of CaO, 0.1-2% of MgO, 0-1.5% of Na2O, 0-2.5% of K2O, 0-2% of BaO and 0-5% of B2O3.
Patent DE-4023887-A1 (DE)
Title: Thermo-forming equipment for plastic film - uses radiation heater to heat up mould tool which is blackened or suitably coated to absorb radiation uniformly
Inventor: HOELZL EMIL
IPC: B29C41/46
Filed: 1990-07-27
Abstract: Equipment for thermoforming plastic films has a mould tool which is radiation heated at one station, covered with the fusible film in another station, and sepd. from the cooled moulding in a third station. The moulding face of the tool has a surface coating which absorbs the radiation heat applied. To avoid the variable heating produced by reflecting surfaces of the mould tool, the tool is e.g. blackened, or, pref., given a coating which is esp. suitable for the frequency range of the radiation heat. The heating oven used, however, requires to have a high reflectivity for effective heating, and, in addn., the tool should be rotated in the oven. Such rotation is partic. desirable when the mould tool has e.g. undercuts. Alternatively the radiant heater itself can be rotated about the tool to produce uniform heating. These actions have the effect of optimal utilisation of the energy provided. ADVANTAGE - The system heats the film efficiently (unlike earlier but similar equipment).

The shanks of the strips are placed under spring-pressure by bring angled into the base. USE/ADVANTAGE - Full Faraday cage effect and can be constructed as intermediate walls in an existing building for protection against e.m. interference radiation outside or against internally emitted radiation of an electronic installation, e.g. to preserve secrecy of information.

Title: Pulse-jet aircraft engine -  has curved pipe instead of usual floating disc valve for higher thrust with lower weight
Inventor: WERDING HANS J
IPC: F02K9/00
Filed: 1990-09-03
Abstract: The pulse jet aircraft engine has a curved pipe (1) which replaces the usual floating disc valve. This curved pipe enables combustion air to be drawn into the combustion chamber and at the same time allows the combustion gases to flow out to generate the required thrust. The curved pipe is made from sheet copper or from enamelled sheet steel. The curved pipe has less weight and a longer service life than the floating disc valve which it replaces. It is of rugged construction and requires no maintenance and is silent in operation. The sub-atmospheric pressure in the combustion chamber is reduced and the thrust is increased. USE - Pulse jet engine with reduced weight and higher thrust.

The top layer (5) of low friction film is bonded on (6) by a contact or hot melt adhesive. The assembled structure can fit on to any shape; the surface film (5) and core (3) are chosen to allow bending to a very small radius without creasing. The complete prod. is partic. useful in applications needing both a seal and also use with sealed faces which move relative to each other. One example is as seal for a glass pane, e.g. a car window, where the prod. absorbs vibration. ADVANTAGE - The prod. is suitable for use as a seal. In addn. however it has good low friction and bending strength properties. It does not crease at its low friction surface. (1/4)

Title: Drill for producing small back-tapered blind holes - has longitudinal tapered slot with sliding pin allowing tool bit to be expanded in hole
Inventor: SPREITER JOHANN ULRICH
IPC: B23B51/00
Filed: 1991-03-11
Abstract: The shank (1) of the drill fits into the chuck of a fixed or portable drilling machine. The body (3) is reduced in dia. towards the cutting end and is split down the axis by a tapered slot (4).

This feeds the toolbit (12) outwards and form machines a back taper (9) in the previously drilled blind hole. A non-rotating outer ring (14) on bearing (13) enables the bush to be moved forward and back by hand or other means to produce the back taper form and allow the drill to be withdrawn. USE/ADVANTAGES - Back tapers and similar forms can be simply produced in small holes.

Title: Sand filter bed - uses untreated and cleaned fluid in a sec. circuit to remove particles from the sand and allows a redn. in the water needed to clean the sand
Inventor: HOMPF DIETER
IPC: B01D24/30
Filed: 1991-06-04
Abstract: In the filtering system for fluid soiled with particles, the sand of the filter bed which is loaded with the filtered particles is cleaned in a sec. circuit using a part of the dirty fluid which still has to be filtered. This is directed at the sand in a counter stream, so that clinging particles are detached from the sand and removed. Pref. the part of the untreated fluid, for use in the sec. circuit, is given a spiral flow pattern to act against the movement of the sand and particles through gravity. The vol. of untreated water used in the sec. circuit and/or the flow speed can be adjusted according to the fluid flow through the sand filter bed in the prim. circuit as the sec. circuit uses a diversion from the sand filter bed. ADVANTAGE - The operation reduces the amt. of clean water needed to clean the sand of the filter bed to a min., e.g. using 2-3% of the cleaned water.
