Title: Non circular container prodn by preforming a reinforcing sheet - and applying thermoplastic film to interior of preformed sheet
IPC: B29C51/16
Filed: 1974-01-10
Abstract: A non circular container is produced by preforming a reinforcing sheet (e.g. plastic, aluminium, cardboard), by forcing it into an annular space formed between a female mould and a male mould located in the female mould. The male moule is then pref. removed from the female mould and a plastic film (pref. pre-heated) in forced (pref. by air pressure) against the inner surface of the preformed reinforcing sheet so that the film adheres to the reinforcing sheet. A non-circular container is simply produced and the plastic film adheres securely and at all points to the reinforcing sheet.

Title: Device for preventing windscreens of motor vehicles from becoming dirty
Inventor: HAVRANEK VACLAV
IPC: B60J1/20
Filed: 1979-01-27
Abstract: With this device, a kind of air curtain is formed in relation to the external face of the windscreen in that, centrally at a distance from the windscreen on the front vehicle bonnet in the direction of travel (F), a flow element (1) is arranged which deflects the air flow (S1, S2) from the windscreen, has blade-like side faces (21, 22) provided with flow guiding edges (41, 42) and widens conically rearwards. The two side faces (21, 22) which are arranged on both sides of the longitudinal axis (X) in symmetrical fashion are shaped in such a way that an air flow (S1, S2) which propagates conically towards the windscreen is formed, by means of which all the extraneous bodies, such as for example insects which fly counter to the direction of travel (F), are deflected upwards from below over the windscreen without striking it. <IMAGE>

Title: Controlling shifts in dams across valleys - by precision distance measurements between dam and fixed terrain points
IPC: G01B7/16
Filed: 1974-04-17
Abstract: The invention provides a more precise and more economic method of effecting measurements to determine the occurrence of slips or displacements in barrages or dams, occurring as a result of the loading and unloading of the dam by water pressure changes. The method consists in making precision distance measurements only between fixed terrain points on the one hand and points on the dam on the other hand. The use of conventional methods of balancing calculations can ensure that the accuracy of the surveying is correspondingly enhanced. Modern devices are available which allow distances over 1 km to be measured with a middle quadratic error of 1.5 + 2d times 10 to the power of minus 6mm, d being the distance in mm.

Title: Method of recovering the heat flowing off from a hot body and accumulator container for implementing the method
Inventor: OPLATKA GEORG DR
IPC: F28D20/00
Filed: 1980-07-23
Abstract: In this method and the device for recovering the heat flowing off from a heat accumulator (1), a liquid or gaseous fluid is conveyed forcibly through a fluid-conducting structure (4), in countercurrent to the heat flowing off outwards from the heat accumulator (1), in the direction towards an inner casing (3) containing the accumulated medium. The fluid absorbs in this case the major part of the outwardly flowing heat and in doing so, by the time it has reached the outer surface of the inner casing (3), achieves a temperature which is only a little below that at the outer surface of the inner casing (3). The fluid heated in this manner can be used thermodynamically advantageously by e.g. being mixed with the heat accumulator contents or being used for heating or process purposes. <IMAGE>

Title: Mechanical digital display unit - has screens for display mounted on levers pivoted behind display wheels and activated by pushbutton
IPC: G09F9/37
Filed: 1975-09-17
Abstract: The mechanical digital display unit has screens (4) carried by a hinged lever (7). This lever (7) can oscillate around its hinged axis (9) and can displace itself parallel to it. This produces movements of the screen along two displacement directions. The lever is controlled by a bidirectional cam (13) which produces at the same time oscillations around the lever around its hinge axis and displacements parallel to it. The screen levers (7) are acted on by an elastic resetting element (21). This element 21) normally maintains them away from the cam. A manually actuated control mechanism acts on the levers. The mechanism brings the levers into contact with the cam (13). The control mechanism has a push button (18). This push button acts, via a spring, on the levers (7) carrying the screens (4). The push button (18) displaces the levers against the action of the reset element and brings them into contact with the control cam.

Title: Edging tape having tassels, prodn. - in which tassels are automatically introduced into loops of a support band
IPC: D04B25/06
Filed: 1973-03-01
Granted: 1974-09-27
Abstract: A decorative edging tape includes a support band formed by a zig-zag configuration of weft yarns fed from yarn guides mounted by pref. L-shaped arms on support bars which are oscillated longitudinally by a cam, and by warp yarns which are introduced into the zig-zag configuration of weft yarns by longitudinally movable needles. A sliver destined to form a tassel is moved by a sliver guide to the edge of the support band, and one of the yarn guides is moved adjacent the sliver such that the weft yarn it is guiding extends from the edge of the support band. The support bar is then rotated by e.g. a cam device which is unaffected by longitudinal movement of the support bar, such that the yarn guides moves longitudinally of the tape and passes over the sliver whereby when the yarn guide finally moves the weft yarn back into the support band the sliver (forming a tassel) is held in a loop of the weft yarn. The tassels are secured to the support tape automatically, thereby eliminating a previously manual operation.
