Patent DE-4214270-A1 (DE)
Inventor: WEISSER FRITZ DIPL ING
IPC: G11B15/29
Filed: 1992-04-30
Abstract: 2.1 To improve the "rewind" search mode, on modern recorders which operate by the helical-scan method the capstan shaft is arranged on the drive chassis outside the region intended for the tape cassette. However, with the capstan shaft arranged in such a way, the control mechanism and structural design for actuating the pinch roller are also relatively elaborate. The object is to provide a pinch roller actuating device which can be produced inexpensively and with which frictional losses which lessen the pressing force for the pinch roller against the capstan shaft can be reduced. 2.2 The actuating device, which can be swivelled about a swivel axis (423), essentially comprises a pressure lever (3), bearing the pinch roller (30), a drive lever (42) and an intermediate lever (41), by means of which a spring (5), provided as an energy store for pressing the pinch roller (30) against the capstan shaft (14), is prestressed. Arranged parallel to the pinch roller (30) on the pressure lever (3) is a conically shaped lift roller (35), by means of which, in interaction with a second guide (75), a lifting movement can be superimposed on the swivelling movement of the actuating device. 2.3 In particular for video recorders in which the capstan shaft is outside the cassette region and the pinch roller in the position of rest is sunken in a clearance in the cassette. <IMAGE>

Title: Fluid-assisted injection moulding process - has variable throttle in fluid injection nozzle to change vol. flow of fluid into cavity and enhance product surface
Inventor: SAUER ROLAND DIPL ING
IPC: B29C45/17
Filed: 1992-05-08
Abstract: In a fluid-assisted thermoplastic injection moulding process the wall thickness of components can be altered by injection fluid through a nozzle (1) in the tool wall. The nozzle may be integral with or separate from the injection nozzle for the thermoplastic. Volumetric fluid flow is varied by changing the throttle cross-section of the injection nozzle. A device for altering flow is incorporated in the outlet (4,5) from the nozzle. USE/ADVANTAGE - For varying wall thickness of thermoplastic mouldings during moulding. Reduces time from the end of thermoplastic injection to the build up of pressure in the tool cavity and therefore enhances outer surface finish.

Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1992-08-26
Abstract: An optical cable (OC) mfg. process involves introducing one or more optical fibres (VL1-VLn) and filler (FM) into a tube formed from strip (BD) and stranding an external reinforcement (AD1-ADn) onto the tube, the novelty being that the tube is passed through a torsion preventer (TS) immediately before application of the reinforcement.

Title: Windscreen-wiper device
Inventor: EPPLE ANTON
IPC: B60S1/40
Filed: 1993-02-09
Abstract: To avoid wedge-shaped, non-wiped windscreen areas along the A-pillar of motor vehicles it is known to rotate a wiper blade during wiping relative to a wiper arm in a manner controlled by a connecting rod. In this connection, a wiper-blade frame itself, or a connecting part attached thereto, is coupled to the free end of the wiper arm about an axis, which is perpendicular with respect to the wiping plane, and the relative rotation is brought about by means of a connecting rod which is coupled on the opposite side of this axis of rotation via a lever and which runs essentially along the wiper arm in a manner such that it is hidden from view. The windscreen-wiper device according to the invention has a slotted guide link (2, 4) for the displaceable mounting of the wiper-blade frame (9) on the free end of the wiper arm (1), the connecting rod (6) causing, during wiping, the displacement within the slotted guide link (2) for the purpose of rotating the wiper-blade frame (9) relative to the wiper arm (1). In this arrangement, the connecting rod is not subjected to torque transmitted by the wiper blade. Use in the motor-vehicle industry.

Title: Arrangement for guiding a printer carriage in an ink jet printer
Inventor: MEINHOF ANDRE-H
IPC: B41J25/316
Filed: 1993-05-17
Abstract: The invention relates to an arrangement for guiding a printer carriage (20) in an ink jet printer. Starting from a paper guide (11) which is mounted resiliently on a transporting roller (10) for transporting a recording medium (12), it is proposed to mount the printer carriage (20) near to its centre of gravity (40) at a first and a second guide point (31, 32) so as to be pivotable and displaceable on a guide rod (30). Furthermore, a guide knob (23) is provided, which is mounted as a third guide point (33) on the paper guide (11). It is proposed optionally to provide a fourth guide point (34) which is supported resiliently on a frame (50). Due to the changing material thickness of the recording medium (12) as well as production tolerances and wear, the printer carriage (20) is pivoted about the axis of the guide rod (30) and the distance of the nozzle outlet surface (22) from the surface of the recording medium (12) is thus kept constant. <IMAGE>

Title: Packaging wrapper with touch-and-close fastener
Inventor: HOEFT BERNHARD
IPC: B65D65/10
Filed: 1993-06-23
Abstract: Packaging wrappers of conventional type require adhesive tapes, binding cords, etc. in order to obtain a firm, secure package. The packaging wrapper with a touch-and-close fastener (Velcro) allows a fast, secure package to be obtained which is environmentally friendly, reusable and recyclable.

On the outer side, the touch-and-close fastener (hooks) (2, 3) is arranged and sewn on in this manner. In order to obtain a firm package, the arrangement of the touch-and-close fastener (hooks) is important and it can be sewn on by any desired combinations depending on the use of the packaging wrapper. The sewn-on touch-and-close fastener also allows the packaging wrapper to be extended and widened without other aids by joining a plurality of packaging wrappers together. This type of packaging can be used in transportation and in any industrial and craft operations.   <IMAGE>

Title: Screening profile for window-roller-blind profiles with air slits
Inventor: STROBEL FRIEDRICH
IPC: E06B9/15
Filed: 1993-07-24
Abstract: Rigid screening profiles, which are preferably self-adhesive and fitted on at least some of the window-roller-blind profiles of a window roller blind, having a part which projects upwards or downwards after fitting and conceals the air slits in the connecting webs of the window-roller-blind profiles hanging one below the other in front of a window, reliably exclude the through-passage of light rays, while maintaining the simultaneous through-passage of air. In order to achieve firm connection or bonding of the screening profiles to the window-roller-blind profiles, which are often curved inwards or outwards in the preferred connection region, the connection region of the screening profile is equipped, on the inner side and/or outer side, with parallel longitudinal grooves, with the result that said region can be better adapted to the underlying surface.

Patent DE-4339799-A1 (DE)
Title: Tilt-sensitive switch with bimetallic spring disc or washer
IPC: H01H35/02
Filed: 1993-11-23
Abstract: When the appts. is tilted through an angle exceeding the upper limit, a ball (6) is dislodged from its seating (12) in the base of the housing (7) to strike the inside of a bell-jar (8). This lifts the crosspiece (10) of the plunger (9) causing its pin or bolt (11) to rise and drive a moving contact (3) away from a fixed contact (4), breaking the current path between two connections (15,16). The same result is produced by the spring disc (17) which is normally convex in the downward direction, but at a predetermined temp. snaps into its alternative convex-upward position.

Title: Cartridge belt for self-loading mortar
Inventor: WOESNER ERNST
IPC: F42B39/08
Filed: 1994-05-20
Abstract: The cartridges (1,1') are accommodated alongside each other inside close-fitting links (7), each of which has opposite protrusions (15,17), each containing an opening (11). Adjacent links hinge together via pins (9) passing through the openings and thickened at the ends. The opening in the first protrusion (15) is connected to the belt edge by a passage (13) narrower than the opening and also than the portion of the pin passing through it. A second opening in the link is connected by a second passage (13') to the belt edge. Thus by bending the passages slightly open adjacent cartridges can be slid free in either axial direction. The two passages (13,13') can lead to the same edge of the belt. The thickened portions at the pin ends can consist of transverse lugs, situated symmetrically in relation to each other. They can be rectangular, so that they cannot turn in the links.
