Patent DE-19603068-A1 (DE)
Title: Method of mounting strings on ball game racquets
Inventor: STOFFELS HELMUT
IPC: A63B49/022
Filed: 1996-01-29
Abstract: The racquet consists e.g. of an oval frame with a handle. Strings or cat-gut are woven through the holes in the frame and are attached to a spring strip (1,2) which runs along the outside of the frame. The tension of the string is a function of the deformation of the spring strip.  As an alternative to a spring strip, the string can be looped round and attached to a flexible chord mounted round the frame or it can be attached to a tube which is under pneumatic pressure. When a chord or tube are used, strips of low friction material are mounted between string and chord or tube.

Title: Manufacture of multi:layer sound proofing element
Inventor: STIEF REINHARD
IPC: G10K11/172
Filed: 1996-04-24
Abstract: A sound proofing element comprises two or more layers of which the first layer (1) on the sound facing side consists of an open cell foam and forms the spring and the second layer (4) on the side facing away from the sound consists of a closed cell foam, forms the mass of a spring mass system (6). Both layers (1,4) are bonded together solely by spacers (7) on the second layer (4). In a process for manufacturing a sound proofing element the second layer (4) is placed in an impressing tool to produce a pattern of recesses (8) and at least one of the opposing faces of the layers (1,4) is coated in adhesive before both layers are passed between two rolls to bond together. Preferably the first layer (1) is made of polyurethane and the second layer (4) of a polyolefin. A pattern of recesses (8) in the second layer (4) faces the first layer (1) and surrounds the hemispherical spacers (7). The weight per unit area of recesses (8) is double that of the spacers (7) and the density of material in the recesses (8) is five times that of the spacers. An especially good sound absorption is achieved when the weight per unit area of recesses (8) is 700g/m<2> coupled with a material density in these areas of 350kg/m<3> and the spacers (7) have a weight per unit area of 350g/m<2> and a density of 70kg/m<3>. Dish-like recesses (9) are formed on the noise facing side (10) of the second layer (4) during forming of the spacers (7). The pattern of recesses (8) is produced by placing a flat second layer (4) on a support with grid-like cut-outs corresponding to the outline of the spacers (7) and a punch is pressed onto the grid while vacuum is applied to the rear side.

Patent DE-19629996-A1 (DE)
Title: Cold forming method for enlarging annular rotary damper blank
Inventor: OHL JUERGEN DIPL ING
IPC: B21H1/06
Filed: 1996-07-25
Abstract: The method is used to enlarge a ring-shaped metallic blank (1) rotated about its axis (2), and which is moved through the gap (3) between at least one pair (4) of rollers (5,6). The latter are moved towards each other to reduce the wall-thickness of the blank, while largely maintaining its axial dimension and its volume.  The reduction in wall thickness may result from a compression of the external perimeter (7), and / or an enlargement of the internal perimeter (8). The roller adjustment may also be such that only one roller is moved in the radial direction towards the adjacent roller.

Title: Two=stroke internal combustion engine fuel pump
Inventor: REMBOLD HELMUT
IPC: F02M59/10
Filed: 1996-08-02
Abstract: The air pulse connection (14) issues into the housing space (13) between the diaphragm (41) and pump piston (22). The diaphragm is loaded both sides by springs (15,35) with one spring (15) in a space (13) supported against the diaphragm via the piston (22). The housing space (33) on the obverse of the diaphragm is pneumatically connected to the surroundings. Valves (61,71) respectively serving the intake and delivery paths are arranged in a separate part of the housing. An end stop at the top dead centre of the piston limits the compression stroke and should be arranged in the compression chamber (51) or at housing parts (21,25).  The compression chamber is in a part of the housing which stands separate from the piston guide part (21), and a spring loaded manual feeler in the housing part opposite the obverse of the diaphragm employs the diaphragm to keep the piston clear of its central setting.

Title: Operating handle, especially for plant machinery
Inventor: WILL HARALD DIPL ING
IPC: G05G5/05
Filed: 1996-08-22
Abstract: The operating handle has a grip (1) which can be deflected in at least two main operation directions (12) as well as in intermediate directions. The grip of the handle is in operative connection with a spring (5) which provides a return force and with an arrangement for varying the spring length. This arrangement operates automatically when the handle is deflected. The arrangement for varying the spring length is formed such that the spring undergoes a greater change in length when the handle is deflected to an intermediate position than when the handle is deflected in a main operation direction. The spring may be in operative connection with a curved plate (4) via a spring plate (6). The latter is connected directly or indirectly with the handle grip. When the handle is deflected the spring plate is moved over the curved plate. The handle may generate electrical signals.

Title: Control system for motor vehicle rain sensor
Inventor: KROSTEWITZ WOLFGANG
IPC: B60R16/02
Filed: 1997-01-24
Abstract: The vehicle control system uses a data bus (4) to transfer data between sensors and the different control units. One of the sensors monitors rain or water spray falling on to the vehicle. This sensor is used to vary the engine management system, to close windows and sun-roof, to operate the windscreen wipers, to modify the ABS braking system and, in conjunction with temperature sensors, to warn of imminent icing. The rain sensor (5) is directly linked to the data bus. One of the control systems (1) operates the engine management. Increase of moisture requires a change in the fuel/air mixture and a timing adjustment to ensure optimum engine performance. rain and road spray cool the fuel tank and affect the vaporisation of the fuel. A wet road affects the performance of the ABS braking system.
