Patent DE-3430520-A1 (DE)
Title: Safety tyre
Inventor: LAMPE RUDOLF
IPC: B60C3/00
Filed: 1984-08-18
Abstract: The invention relates to a tyre made of conventional materials for utility vehicles or passenger cars, which, in a modification of known designs, has an enclosed safety chamber inside it, which chamber is provided between two adjacent air chambers in the conventional design. During normal use of the tyre, this safety chamber is under the same air pressure as the two adjacent air chambers but maintains their pressure even if the two other air chambers lose their air pressure due to damage. A particular alternative for the design of this tyre provides for the tread parts which are separated from one another by means of a central groove to have an inclination or rise with respect to the horizontal towards the central groove.

Title: Metering device for liquids, in particular for adhesives
Inventor: MARTIN BERNHARD DIPL ING
IPC: B05C5/02
Filed: 1984-09-27
Abstract: For the drop-shaped application of small amounts of a liquid to a substrate (S), the liquid is fed under pressure via a metering valve (Dv) to at least one metering needle (Dn, Dn'). A liquid droplet metered to the required amount is forced out of the metering needle (Dn, Dn'), which can be lowered onto the substrate (S), and is dabbed on to the substrate (S). In order to avoid damaging the substrate (S), the metering needle (Dn, Dn'), which consists of an elastically deformable material, is designed as a curved spring which deflects when placed on the substrate (S). Preferably two metering needles (Dn, Dn'), which are combined to form a double metering needle, are directly connected to the metering valve (Dv). The metering device is suitable in particular for applying adhesive spots (Kp) to circuit boards, the components subsequently applied being fixed with the aid of these adhesive spots (Kp) until soldering. <IMAGE>

Patent DE-3507456-A1 (DE)
Title: Automatic readjusting device
Inventor: WEILER ROLF
IPC: F16D65/56
Filed: 1985-03-02
Abstract: The automatic readjusting device (1) consists of a spindle (17) and a nut (19), which are connected to one another via a self-locking thread (18). A non-self-locking screwed connection (37) and a first coupling (23) are guided on the spindle (17). When a predetermined longitudinal release play is exceeded, the first coupling (23) acts on part of the non-self-locking screwed connection (37) in such a way that a relative axial motion of the two parts (29, 36) of the non-self-locking screwed connection (37) is converted into a rotation for rotating the spindle (17) relative to the nut (19) in the direction of readjustment. The rotating part (29) of the non-self-locking screwed connection (37) is in frictional engagement (34) with the spindle (17). A second coupling (24) is simultaneously held fixed against rotation and, when the rotating part (29) of the non-self-locking screwed connection (37) is rotated counter to the direction of readjustment, holds the spindle (17) fixed against rotation. On the one hand, this arrangement provides a readjusting device (1) which functions well and, on the other hand, the rotary movements in the direction of readjustment or resetting which occur under the action of shocks on the spindle (17) are avoided. <IMAGE>

IPC: B41J13/16
Filed: 1985-04-01
Abstract: To align paper or when using continuous forms, the paper guide tray (5) and the paper holding bar (27) need to be raised in typewriters, which in known arrangements is effected by separate operating levers.   The invention is based on the object of providing a device on the platen for typewriters or similar office machines, which device allows simple raising of the paper guide tray (5) and the paper holding rod (28). In this case, secure functional positions are always to be guaranteed both in the typing position and in the paper release position. This object is achieved in that a paper release knob (19) is mounted pivotably on the free end (21) of a bearing spindle (3) of the roller platen (2), and in that the paper release knob (19) has a cam (18) for pivoting the paper guide tray (5) and a stop edge (31) for pivoting the paper holding bar (27). As a result, a cost-effective and easy-to-assemble control element is provided for raising the paper guide tray (5) and the paper holding bar (27). The two functional positions of the paper release knob (19) are always guaranteed in a secure manner. <IMAGE>

Patent DE-3516331-A1 (DE)
Title: Process for heating without bellows (bladder) and bag during the retreading of tyres
Inventor: ALBRECHT JOHANNES
IPC: B29D30/06
Filed: 1985-05-07
Abstract: In the process I have developed, the interaction of the suction device with the fed compressed air is of great importance in the heating of retreaded motor vehicle casings. The essential factor of this process is the manner in which, after completion of the heating process, the heating water is removed from the lower part of the now finished casing. This is carried out by means of a suction device which is connected to a flexible hose. By the feeding of compressed air, the process time is reduced to 10-30 seconds. In the case of bellows (bladder) and bag heating, the process time depended on natural gradients and thus the process took up to 5 minutes longer. For the person skilled in the art, my ideas are adequately represented in the text and drawing.
