Title: Gastight vacuum pack for coffee, cocoa, nuts, etc - comprises inner and outer envelopes laminated together with adhesive in such a way that delamination occurs when pack is opened
IPC: B65D81/20
Filed: 1992-11-29
Abstract: A gastight vacuum pack for protecting the flavour and active ingredients of fillings such as coffee, cocoa, nuts, etc. comprises a multilayer envelope with an outer (A) and inner (B) layer(s) firmly bonded together with an adhesive (I), at least at the bonding joints. (I) is spread uniformly over the entire surface of the inside of (A) and/or the outside of (B), and the amt. and adhesive strength of (I) are such that (a) the joints are strong and unbreakable at temps. above 100 deg.C and (b) the adhesive bond between (A) and (B) can be broken at ambient temp. so that (c) delamination of (A) and (B) occurs when the vacuum is abolished. Also claimed is prepn. of an envelope material for the above pack, in which the application of (I) and the prodn. of the breakable joint between (A) and (B) are carried out in one step. ADVANTAGE - The invention provides a vacuum pack which is less expensive in materials and prodn. costs than some prior-art systems (because it has fewer layers), and which does not suffer from an unsightly `orange-peel' effect when opened, because layers (A) and (B) remain bonded together during the filling operation and only separate when the pack is opened and the vacuum abolished. The pack is also less sensitive to temp., and has a smooth outer layer which is readily printed.

Title: Synchronous pedal crank drive for bicycles
Inventor: FLORSCHUETZ FRANZ
IPC: B62M1/36
Filed: 1993-04-07
Abstract: Power transmission in bicycles takes place by means of the pedal crank drive, pedalling downwards normally causing the leg forces to act approximately perpendicularly downwards. In the dead centre positions with the crank position perpendicular the tangential force component is reduced to zero and so the torque is ineffective. The object of the invention is to match the pedal crank drive synchronously to the human build and in this manner, by virtue of uniform use of force in the dead centre positions, to obtain a corresponding torque. This is achieved by virtue of the fact that pedal arms (3) are connected by a swivel joint (4) in a revolving manner to the outside of the crank arms (1). The anatomically shaped pedals (11) are arranged in such a manner that the pedalling angle is adjusted individually via the connecting rod (14) by means of the slide (15) with the clamping lever (16). During pedalling, the leg force pointing permanently in the tangential direction due to the pendulum swing, the crank arm revolves in a circle (A1-A8) whereas the pedal describes a synchronous revolving path in an oval shape (B1-B8), the torque being effected forwards (B8-B1), in the upper part, by a transverse force, due to a pendulum-like dynamic centrifugal force, then downwards by the compressive force (B2-B4) and, in the lower part, rearwards by the tensile force (B4-B6), due to the straight pedal crank in the large arc radius. <IMAGE>

Title: Compressor installation
Inventor: WENZEL HARALD DIPL ING
IPC: F04D25/00
Filed: 1993-04-21
Abstract: The invention relates to a compressor installation for compressing a gaseous medium, with a compressor which is driven by the useful side of a heat engine and is connected to the consuming points via a line, and two exhaust-gas turbochargers which are arranged in the suction line of the compressor and lie in series on the drive side in the exhaust-gas path of the heat engine. In order to be able to improve the overall efficiency of such an installation, it is proposed that the heat engine (40) and the compressor (50) be designed as separate machines and that the drive shaft of the heat engine (40) be connected to the drive shaft of the compressor (50) via a coupling, and that the total volumetric flow of the compressor side at the exhaust-gas turbochargers (21, 23) be fed to the compressor (50) via a line (70, 77, 78, 79). <IMAGE>

Title: Wind wheel having wind boxes
Inventor: TABORI FERENC
IPC: F03D3/04
Filed: 1993-05-27
Abstract: Design: horizontal with impeller. Can be erected on high buildings having flat roofs;     without impairing the appearance of the neighbourhood,   without propellers,   without producing noise,   without a mast (as the case may be),   without the effect of a mast (also with a mast - none),   without a gyroscope effect,   without inherent size limitation,   without incalculable vibrations or resonances,   without loss of wind pressure apart from frictional loss, because the direct or deflected wind acts on the impeller front surfaces only in the direction of rotation. The wind box is mounted rotatably and provided with a wind vane. This first wind vane is arranged in such a way that the wind box always comes to be situated with the wind inlet side in the direction of the wind (that is to say movement by virtue of the free wind energy). The speed control is accomplished in exactly the same way - by means of a second wind vane - by using a shutter (closure) resembling a Venetian blind or roller blind. The second wind vane is at right angles to the first. The deflected wind exits upwards, the direct wind rearwards. Use of wind energy for producing power: relatively small installations, eg. on high buildings for home use; heating, hot water etc.: relatively large installations for input to network. <IMAGE>

Title: Holder for banknotes
IPC: G07D7/128
Filed: 1993-08-06
Abstract: In view of the necessary further work step, the use of the ultra-violet lamps, known for the recognition of counterfeit money, in the till area is time-consuming. The holding devices for bank notes nearby or at the till have hitherto been used within the workflow. The invention is to make it possible to combine the recognition of counterfeit money with the previous use of the holding device. When the paper money is inserted into the clamping batten (6), the paper money is illuminated in colour at the fluorescent points and the watermark shows up in the region of illumination. In the embodiment of the inventive idea, provision is made for placing the illuminating means (1), preferably a gas-discharge lamp (15) (black light), in a housing (5), the housing (5) being connected to the clamping batten (6). The clamping batten (6) consists of cut away material (9) or light-conducting material (3). The holder makes it possible to integrate the authenticity test of the paper money into the currently conventional workflow of the cash-collecting operation, without any extra time being spent. <IMAGE>

Title: Device for measuring small mass or force differences
IPC: G01G23/00
Filed: 1993-10-10
Abstract: For the measurement of small mass or force differences, high-resolution precision balances or devices which are especially tailored to the intended use are used. The technical expenditure and the often complicated handling of the special devices is disadvantageous (for example rotary Coulomb balances, current balances). The new device is intended to make possible the use of relatively insensitive commercially available universal balances (for example electronic kitchen balances). By means of an external lever mechanism, the sensitivity of a universal balance can be increased by powers of ten. The new device is particularly suitable for the experimental investigation of electrical and magnetic forces, without great expenditure. One exemplary embodiment for the measurement of Coulomb forces is shown in the drawing. The symbols are:     (1) Universal balance   (2), (3) Charged metal spheres   (4) Lever of insulating material   (5), (6) Point bearings   (7) Knife-edge bearing   (8) Support, which is firmly connected to the table (11)   (9) Displaceable counter weight   (10) Liquid for damping oscillations   (11) Table   (12) Stand   (13) Scale for reading the distance r   <IMAGE>

Title: Process for regenerating etching solutions
Inventor: BUHR HARALD DIPL ING
IPC: C23F1/46
Filed: 1993-10-12
Abstract: The present invention relates to a process for regenerating ammoniacal copper-containing etching solutions, in which the etching solution and a liquid extraction medium are introduced into an extraction apparatus and the etching solution having a reduced copper content and the extraction medium laden with copper and ammonia from the etching solution are taken off in separate streams (copper extraction). Then, in further extraction apparatuses, ammonia is first selectively extracted from the laden extraction medium into an aqueous solution and copper is then extracted from the extraction medium into a sulphuric acid solution. The extraction medium substantially freed of copper is returned to the extraction apparatus. The invention is characterised by the fact that the copper content of the etching solution after the copper extraction is reduced by using an extraction medium containing hydroxyphenone oxime to values which approach zero g/l of etching solution and that the aqueous solution of the ammonia extraction is circulated. By means of this process, an etching solution virtually completely free of copper is produced with minimum production of by-products. <IMAGE>
