Patent DE-3840419-A1 (DE)
Title: Securing device for a winding shaft
Inventor: UHLENKOTTE WILHELM
IPC: E06B9/84
Filed: 1988-11-25
Abstract: The solution for achieving this object is that the commencement of the catching action is no longer initiated by the built-in detent pawl, as in the securing device according to the main patent, but by means of a second worm wheel (2). This performs the function of the detent pawl and of the ratchet wheel. This affords the possibility of mounting the last two thread flights (a + b) of the worm drive shaft displaceably, in order thereby largely to prevent abrasion or wear of the flights. The two displaceable thread flights a + b on the right and left of the worm of the drive shaft engage inter alia into the worm toothing of the second worm wheel (2). In the event of a breakage of the thread flights on the worm drive shaft (3) and of the toothing of the first worm wheel (4), the roll-up door is reliably prevented from crashing down by the thread flights pushed onto the drive shaft on the left and right and by the toothing of the second worm wheel (2). The catching action and the desired braking take place in the way described in the main patent and are characterised in that both the winding shaft (1) and the second worm wheel (2) have at least one recess (6/7), the said recesses together forming a cavity (8), the ends of which converge in the circumferential direction, and in that a rolling body (9) consisting of a deformable material is arranged in this cavity (8). In the event of a fault, the rolling body (9) is jammed within the cavity (8), with the rolling body being deformed, in such a way that [lacuna]... Original abstract incomplete. <IMAGE>

Title: Cylinder for paint rollers and method for its manufacture
Inventor: VAHLE WOLFGANG
IPC: B05C17/02
Filed: 1989-01-26

Title: Process for regenerating a laden pressurised scrubbing medium
Inventor: RANKE GERHARD DIPL ING
IPC: C10K1/14
Filed: 1989-01-26
Abstract: A process for regenerating a pressurised scrubbing medium laden with scrubbed-out gas components by expansion of the scrubbing medium with liberation of expansion gas and subsequent stripping of further scrubbed-out components with the aid of the expansion gas is described.

Patent DE-3922884-A1 (DE)
Inventor: WITTMANN DIETER
IPC: F02D9/06
Filed: 1989-07-12
Abstract: The invention relates to an engine brake for air compressing internal combustion engines. To improve the braking power of the internal combustion engine, the invention proposes to combine a universally known engine brake using throttling of an engine exhaust by means of a throttle valve with a likewise known engine brake in which an exhaust valve (1) can be raised not only by the cam mechanism (2) but can also be raised slightly by a piston (3) during the exhaust stroke. By virtue of the combination according to the invention, braking work is performed not only during the exhaust stroke but also during the compression stroke, with the result that the braking power can be increased by about 50 to 60% and by 80 to 90% compared to the nowadays customary exhaust brakes and enters the range of the useful power output.

Patent DE-3925047-A1 (DE)
Inventor: BRAISCH PAUL DR ING
IPC: H05B6/06
Filed: 1989-07-28
Abstract: A process is useful for controlling processes for heat treatment of metals in function of the material during inductive heating in a closed control circuit if otherwise, with predetermined and exactly reproducible machine parameters, the processing result is affected by the material properties subject to a random change. This could occur in particular as a result of a random change in the metallurgical transformation behaviour, the electrical or magnetic properties and the like. The variation of the process control parameter(s) (temperature, heat output, and similar quantities) with time is analysed in real time and in relation to the deviation from a predetermined function. The deviating material properties are derived from the result. Any necessary correction of these control parameters is carried out during the current working cycle, so that each random change in the material properties is compensated and its influence on the processing result is limited.

IPC: F27B9/26
Filed: 1989-10-18
Abstract: A tunnel kiln has a preheating, firing and cooling zone with two tracks on which the articles pass in opposite directions through the kiln.  The preheating zone of one track corresponds to the cooling zone of the other track.  Hot gas is extracted by blowers from the bottom of the cooling and preheating zones and injected at the top of the preheating and cooling zones in a 10 sec. cycle which alternates between the two tracks. The preheating zone (6) of one track and the cooling zone (1) of the other track have at the bottom, outlets (20, 23) for the extn.  of hot gas which is blown through the inlets (21, 22) against the charge (27).  The motorised valve (24) is reversed every ten seconds and blows the gas through the openings (18, 19) on the charge in the cooling zone (6).  The inlets (18, 22) are T-shaped.  The unit (28) is a filter for S and F compounds and the unit (17) is a blower. ADVANTAGE - This makes a much better use of the invested heat than the conventional system.

Domestic universal adhesives, based on a largely solvent-free aq. dispersion of polyurethane (which uses a polytetrahydrofuran type polyol mixt. with isocyanate and a functional component to form a salt in aq. soln) are applied by using a casting (at least round the outlet) made of PTFE, polyamide, polyethylene or epoxy resin and a sealing plug of glass, saphire, polyamide, homo-polypropylene or polyoxymethylene. A tube (1) with air inlet at the top end (2) is fitted with the applicator end (3) this consists of the casing (4), the bottom outlet (5) and the screwed-in piece (6). This piece (6) also screws into the main tube (8). It (6) has a centre bore (9) for the adhesive which is fed from a capsule (12). ADVANTAGE - The device is suitable for applying the types of adhesive listed, whereas applicators hitherto have been unsuitable because the adhesives stick to them and prevent further use.

Title: Friction clutch coupling - has at least one control assembly with spring, and shape memory metal
Inventor: HOFFELD HARALD
IPC: F16D43/21
Filed: 1990-03-26
Abstract: The frictional coupling for detachably joining two drive-pieces (1, 2, 5, 6) connected in one line incorporates at least one control (10) comprising components made of shape memory metal.  Tension force in the form of a spring (8) is exerted on the drive pieces causing a 'closing' action.

Title: Construction of building base floor - involves application of lateral enclosure and floor support and granular rough ballast
IPC: E02D19/06
Filed: 1990-04-04
Abstract: The rough ballast is applied to the floor support and then drawn away for profiling purposes.
