Title: Container to be opened by the pressure of two fingers
Inventor: CHRONZ ERICH DIPL ING
IPC: B65D77/30
Filed: 1981-01-20
Abstract: The invention is intended to allow easy opening of containers of any size and any content by single-handed operation, for example by the pressure of two fingers. The container, bag or the like consists of a sturdy ring of any material and various shapes. It is widened at the top in such a way that an opening is produced, in which a small collapsible plate fits. The latter is connected at its ends to the outside cover of the container in such a way that, when the small plate is collapsed, the container cover of any material is drawn upwards over the ring in such a way that it tears open at the bottom and exposes the contents. The tearing-open of the cover is facilitated by a suitable connection. The cover can be pulled apart even without the small collapsible plate and without widening the ring at the top. <IMAGE>

Title: Device for releasing wheel nuts and wheel bolts in motor vehicles
Inventor: WEINHOLD KARL DIPL ING
IPC: B25B17/02
Filed: 1981-03-24
Abstract: Releasing these bolted connections with a conventional spanner is often not possible at all or is only possible with the expenditure of considerable force. Physically weaker persons in particular are therefore often unable to carry out a wheel change. By the use of a device designed according to the invention, very tight wheel nuts and wheel bolts can now also be released. Such a device is characterised in that a torque-transmission means with an input shaft and an output shaft is designed in such a way that it can be put onto the wheel nut or the wheel bolt when a socket spanner is attached to the output shaft, in that the torque-transmission means can be locked against rotation about the axis of the output shaft, and in that the input shaft is designed for mounting a hand lever. <IMAGE>

Title: Controllable-pitch propeller and device for adjusting the blades
Inventor: GRADEWALD REINHOLD ING
IPC: B63H3/08
Filed: 1981-05-08
Abstract: An adjusting device which does not rotate with the propulsion shaft is described for a propeller driven via angular gearing and having adjustable blades. The characterising feature of this device is that the yoke adjusting the propeller blades is supported in such a way that it can be loaded by tensile and/or compressive forces, which yoke converts its translatory movement into a swivelling movement of the blades. Furthermore, a locking device for the blades is shown which is based on positive fixing of each blade in its set position and is operated without additional control outlay. The device is further characterised in that the blades are held in position without pressurising.
Patent DE-3119668-A1 (DE)
Title: Television set
Inventor: HEISTER HEINZ ING GRAD
IPC: H04N5/12
Filed: 1981-05-18
Abstract: In television sets having a large number of lines with a high line frequency, the problem occurs that because of the unavoidable delay in generating the horizontal deflection currents, a phase error arises between video signal and line deflection. To eliminate this error, it is proposed to delay the line synchronisation pulses, which are allocated to the video signal for the nth line, after separation in an amplitude filter (1) in such a manner that they trigger the line deflection for the (n+1)th line. The invention is used for television sets having a large number of lines. <IMAGE>
Patent DE-3120634-A1 (DE)
Title: Device for removing and shortening hair
Inventor: MUMM HANS
IPC: B26B19/14
Filed: 1981-05-23
Abstract: Known devices which are used as shavers for removing and shortening hair are preferably composed of a semicircular perforated sheet, beneath which a cutting head can reciprocate in the longitudinal plane of the perforated sheet. A design of this type provides a relatively large active cutting surface, such as is desirable for the removal of bristles from the chin. A razor of this type cannot, however, be used for shaving hair-growing regions which are not easily accessible. The invention is intended to remedy this and is characterised in that the surface of the perforated sheet forms a complete circle and an essentially cylindrical hollow body with a small diameter, in which there rotates a rotor which is equipped with blade-carrying rails. It is possible in this fashion to shave, without difficulty, hair-growing regions of the human body which are not easily accessible, in particular, without unwieldy cutting surfaces impeding such a process.

Title: Retractor for seat belts
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/34
Filed: 1981-06-09
Abstract: The invention relates to a retractor for seat belts with a housing designed specially for simplified assembly. A technological further development of the retractors will take place in the very near future primarily in such a way that the components will be laid out in a manner suitable for supplying and handling them for an automatic manufacturing process in order to obtain advantages in terms of cost. This object is achieved by the present invention essentially by virtue of the fact that the housing is assembled from two housing legs (3 and 4) and a housing rear wall (5). By virtue of a design of this type, the retractor (1) can be assembled in a cost-effective manner by a simple bringing together of the spring assembly (17), the shaft assembly (19), and the system assembly (18). <IMAGE>

Patent DE-3138427-A1 (DE)
Title: Device for lifting the drop weight of a soil-testing rig or the like
Inventor: GLATT PETER
IPC: E02D1/04
Filed: 1981-09-26
Abstract: A device (11) for lifting the drop weight (7) of a soil-testing rig (1) or the like consists of gripping jaws (16, 17) attached to a slide (14) which can be driven vertically in a rectilinearly oscillating manner. By means of the gripping jaws (16, 17), the drop weight (7) can be coupled in its bottom dead centre position automatically to the slide and can be released from the latter after an adjustable length of travel. The gripping jaws (16, 17), designed as clamping jaws, are here pivotably mounted eccentrically on pins (18, 19) so that the clamping bar attached to the drop weight (7) is clamped in place automatically and can be released by means of vertically adjustable run-up ramps (28, 29). The drop weight is therefore lifted by the set drop height during every stroke, and in fact irrespective of the degree to which the soil sample has already been compacted. When the slide reverses to move upwards, the clamping bar is in the process clamped in place between the clamping jaws; the actual position of the drop weight therefore has no effect on the distance to be covered. And since the clamping connection can be released at virtually any point, the drop height is infinitely variable. <IMAGE>

Title: Air drying device for pneumatic brake systems of motor vehicles
Inventor: UNGER HANS
IPC: B60T17/00
Filed: 1981-10-12
Abstract: The air drying device for pneumatic brake systems of motor vehicles with trailer coupling has an air dryer (3) with a drying cartridge (4), which during regenerating phases can be regenerated by compressed air flowing back from the brake system and/or an air storage reservoir (7'). The size of the compressed air flow returning during the regenerating phase is determined by a nozzle (14), the through-flow cross section of which, depending on the coupling state of the trailer coupling, can be switched between a small through-flow cross section in the uncoupled state and a large through-flow cross section in the coupled state. When the motor vehicle is running alone therefore this produces a small compressed air return flow for regeneration of the drying cartridge (4) corresponding to the low loading of the drying cartridge, whereas when operating with trailer the regenerating compressed air return flow is increased in line with the increased loading of the drying cartridge (4) caused by the increased compressed air demand. The trailer coupling may have a coupling head (8) with switch device switchable as a function of its coupling state, the switch device by way of a control line (9) determining the position of a nozzle needle (19) determining the through-flow cross section of the nozzle (14). <IMAGE>
