Title: String gripping tongue for tennis racquet - has pressure plates moved by single cam-action lever to grip already-strung sections
Inventor: HAHN RICHARD
IPC: A63B51/14
Filed: 1979-04-18
Abstract: The gripping tongue is for the stringing of tennis racquets, used to hold already strung sections during the threading in stage of the end of the string before the next tensioning stage. The gripping tongue includes a centre section with a thickness corresponding to the distance between adjoining strings. Pressure plates are pressed against the centre section on both sides, which tend to diverge from the centre section under spring tension. The pressure plates can be moved towards the centre piece through a common swivel lever and an actuating pin fitted to it. The actuating pin (8) is a rotating shaft with the rigidly connected swivel lever turning round the axial direction on one side against the actuating pin and on the other side against the pressure plates.

Title: Hydrocarbon cracking or reforming furnace - with internally subdivided ceramic tubes for gas mixt.
Inventor: WESSER FRIEDHELM DIPL ING
IPC: B01J8/06
Filed: 1979-06-11
Abstract: Thermal conversion furnace for gas mixts., specially for cracking and reforming of hydrocarbons, includes at least one straight tube, made of ceramics, in which the gas mixt. is passed through the furnace space, heated by burners. The inside of each tube is subdivided by radial, parallel or concentric ribs into a great number of separate flow chambers, with walls which are coated by a catalyst if the process requires it. The tube or tubes are anchored in the furnace hearth and are free to slide in its ceiling. A helical arrangement of the chambers improves the heat exchange conditions by added turbulence. This eliminates the operational difficulties with metal tubes. The reactions can now be carried out at a higher temp. level and with a higher efficiency.

Title: Warp-knitting machine guide bars - is spring-loaded in shogging direction with cables round superimposed eccentric guide pulleys
Inventor: LINCKE PAUL
IPC: D04B27/26
Filed: 1979-06-26
Abstract: In a towing layout for the guide bars of a warp knitting machine, to move them in the shogging direction, a cable guide roller has a section which is concentric and a section which is eccentric to its axis of rotation. The part of the cable going to the guide bar runs off and back on to the concentric section, whilst the part extending towards the anchorage runs off and on the eccentric section of the guide roller. For pref. the guide roller is formed by two pulleys one upon the other, and the end of the tow cable is adjustable under spring-loading. The system maintains constant tension on the guide bars, whilst at the same time reduces the space necessary for the mechanism.

Title: Target mat for e.g. tennis training - uses two metal-coated plastics sheets separated by perforated sponge sheet and completing circuit upon impact
Inventor: ZIPPEL GUENTHER
IPC: A63B63/00
Filed: 1979-08-08
Abstract: The target mat for tennis training is placed in a suitable position on the court. A ball striking the mat makes a contact which operates a score counter and gives an acoustic or optical indication. The mat consists of two rectangular sheets of flexible plastic, bonded together all round the edges. The inside surfaces have metal coatings connected at one edge to a cable with a plug for connection to the indicator. The metal coatings are separated by a sheet of compressible plastic sponge. The sponge sheet has numerous perforations which allow the metal coatings to make contact when a ball strikes the mat. The diameter of the perforations depends upon the thickness of the sponge sheet and the ball diameter.

Title: Space cell panels bonding - by moisture curing and expanding polyurethane resin
Inventor: STAUDENMAYER WINFRIED
IPC: C08G18/10
Filed: 1979-11-21
Abstract: Polygonal space cells for use as kiosks or ticket offices consist of panels with windows and doors which are joined together by an adhesive. The panels are assembled from two outer chipboard plates which are spaced by a wooden frame, with the space filled by expanded rigid polystyrene. The panels are bonded together by applying at the butting faces a foam layer of a moisture-curing one-component polyurethane resin. This forms a foam and is cured under the effect of moisture which exceeds the air humidity. Such an adhesive fills up all cavities. The excess moisture is simply attained by mixing the polyurethane with an amount of water.

Title: Retroreflector plate - with polygonal curved light entry areas in front differing in size or shape from rear reflection areas
Inventor: SCHWAB KURT DR
IPC: G02B5/126

Title: Metal strip coating removal - before welding by acid, alkaline solution, rotary brushes and drying
Inventor: RIX LEONHARD
IPC: B23K9/235
Filed: 1980-12-13
Abstract: Metal strips and sheets which are coated with paint, plastics or zinc must be bared before they can be welded together. These coatings are removed in the areas of an intended weld by a wet method and/or by revolving brushes. The wet method includes the application of an acid, followed by neutralisation by an alkaline soln., and drying. This eliminates difficulties of other methods, e.g. through grinding dust causing short-circuits in the welding ring.
