Title: Opening device
IPC: E05F15/57
Filed: 1988-03-29
Granted: 1988-12-22
Abstract: The invention relates to a device for opening and closing window-like or door-like openings in sheet-metal booths surrounding machine tools, consisting of a lifting gate with at least two laterally guided gate elements disposed vertically one above the other in the closed position and at least partly overlapping in the open position, for the vertical movement of which drives are provided. The characterising feature of the invention is that:   a) fastened to both sides of each gate element (3a, 3b) in the closed position is one pneumatic spring (5) each pressing it into the open position, b) the force of the pneumatic spring (5) is matched to the mass of the gate element (3a, 3b) in such a way that only a small force is necessary to move the gate elements (3a, 3b), c) on both sides of the gate elements (3a, 3b), one drive (6) each is fastened to the lowermost gate element (3a) in the closed position, upon the actuation of which drive (6) the gate elements (3a, 3b) can be moved into the closed position, d) the top gate elements (3b) in the closed position have drivers (7) at the bottom for driving by the bottom gate elements (3a).   <IMAGE>

Title: Collapsible, portal-crane-like assembly device
IPC: B66C5/02
Filed: 1988-12-02
Granted: 1990-05-23
Abstract: In machine halls, where for lack of space neither crane vehicles nor any lifting means attachable to the ceiling can be used for erecting long, heavy assembly parts, there are often enormous problems. The object of the invention is to create a special device which is simple to dismantle and can be quickly transported to its place of use by means of an estate car in order to thus safely erect long parts even in restricted space conditions. The object is achieved in that a portal-crane-like device is rolled with four steerable wheels over the part to be erected and the crane rope is then hung approximately above its centre of gravity so that this part rises up during the lifting and comes to a stop next to the crane bridge. After the work has been carried out, it is possible to dismantle this crane-like device very quickly by hand and to fit the individual parts into each other and thus accommodate them in a very small space. In an embodiment of aluminium, the weight can be reduced to such an extent that transport by car becomes possible. <IMAGE>

The device is principally used for the testing of recycled bottles.
Patent DE-4120593-C1 (DE)
Title: Focussed acoustic pressure pulse source - comprises circular zones similarly activated but of differing diameters and foci
IPC: G10K11/30
Filed: 1991-06-21
Granted: 1992-09-17
Abstract: Several zones (Za,Zb,Zc) surround each other in rings which are activated independently of each other to deliver pressure pulses. Their pressure pulses propagate together at different foci (Fa,Fb,Fc). In relation to each zone, measurements for focussing are taken. The measurements for focussing for complete zones are identical in the manner of working. The zones have different focal lengths, and are arranged so that the focal length increases with increasing outside dia. of the zones. Acoustic lenses (25,25a,25b,25c) are assigned to the ring shaped zones. The zones can be spherically curved. The drive can be from an electrical generator or e.m. coils. USE/ADVANTAGE - Medicine, e.g. lithotripsy, pathological biological tissue changes or bone complaints. Material testing via probes. Allows focus point to be offset w.r.t. source. Propagation paths from various zones differ from each other as little as possible. Level of focus tends to be independent from its position.
Patent DE-4138955-C1 (DE)
IPC: F16B15/04
Filed: 1991-11-27
Granted: 1993-04-29
Abstract: In order to fasten structural parts on a porous underlying surface such as, for example, gas concrete, a nail for gas concrete is formed from a half-round metal rod which is grooved transversely to the longitudinal axis. The points, projecting away from each other, of the nail are pushed through the splitting disc (7) and the nail is driven into the material. The transverse bar (6) of the splitting disc acts on the two shank halves of the nail with a lateral force which spreads out the nail in the form of a claw, independently of the effect of the underlying surface. In addition, the transverse grooves of the nail improve the load-bearing capacity of the connection in the gas concrete. <IMAGE>

Granted: 1995-01-12
Abstract: A digital filter bank for frequency-separation of a frequency-division multiplex signal sampled at the sampling frequency fA and composed of at most L individual signals of the band width B, a real input signal being converted into a complex output signal and the sampling rate being reduced, characterized in that the real input signal is distributed to M filter branches at the rate of the input sampling rate by means of a rotating switch, the processing rate being reduced by the factor M in the filter branches, in that, in the individual filter branches, the samples of the input signal are multiplied by the filter coefficients for the pth filter branch and are combined to form the complex filter branch output signals and in that the filter branch output signals are frequency-shifted by means of complex multiplication and are combined to form complex filter output signals. Used in HMM multiplexers or demultiplexers, respectively, particularly for multi-channel and broad band channel systems in which the input sampling rate of the demultiplexer or output sampling rate of the multiplexer, respectively, is too high for being implemented for signal processing by means of conventional technology even after the usual halving of the sampling rate of the input stage.   <IMAGE>

Title: Drain and process for drainage of an area involve chamber with inlet via which catchment water can flow inwards and outlet via which catchment water can be pressed outwards
Inventor: NICOLAI ROEL
IPC: F04F1/16
Filed: 2006-06-26
Granted: 2008-01-02
Abstract: The drain and process for drainage of an area involve a chambe with an inlet via which catchment water can flow inwards and an outlet via which catchment water can be pressed outwards. The water is pressed out of the chamber by compressed air or with a combustible gas, obtained by an explosion initiated in the chamber above the water. The chamber (1), made of concrete, steel or a material reinforced with plastic fibers, has an inlet (2) with an inlet valve (3), via which catchment water can flow to a specific level and an outlet (4) provided with an outlet valve (5) via which water can drain away. On the chamber a valve (6) is fitted and operated by a solenoid (7), with which copressed air is allowed into the chamber at a pressure which expels the water present in the chamber via the outlet. An alternative is with an explosion chamber with a solenoid-operated valve via which methane is admitted into the chamber where it mixes with the air present. The gas/air mixture is ignited by an ignition system, expelling the water present. A further valve with a solenoid after some time prevent the pressure in the further valve with a solenoid after some time prevent the pressure in the chamber becoming too high and instead of a relatively powerful explosion a series of minor explosions ensues.
