Patent DE-3643004-A1 (DE)
Inventor: BAUER PETER
IPC: H04W84/10
Filed: 1986-12-17
Abstract: To verify that the handset of a cordless telephone unit is still within the radio coverage area of the fixed station, rather than attempt to establish connection with the switched network and verify contact as a result of receiving a dial tone, or dialing a special number in the network, a user can merely activate a radio coverage verification circuit in the handset and fixed station. Through use of these circuits, in addition to the identification number of the station, a code is transmitted. The identification and code, when received by the opposite station, are verified with number and code values stored in that station, and the number and code are then retransmitted as an acknowledgement signal. An annunciator in the handset provides a visual or aural warning to the user if the acknowledgement signal is not received, indicating that the handset is not within the radio coverage area of the fixed station.

Patent DE-3718135-A1 (DE)
Title: Method and apparatus for producing water oscillations in an air-pulsed jigging machine for processing minerals
Inventor: STRAUSS WERNER
IPC: B03B5/24
Filed: 1987-05-29
Abstract: In order to be able to put air-pulsed jigging machines, in particular for processing minerals, successfully into operation and to be able to operate them successfully, they had hitherto to be provided with special valve control devices, compressed-air lines and the like, which involves an increased outlay in terms of material costs and operating costs. According to the invention, however, these disadvantages can be avoided in a simple manner in that the inlet and outlet opening (7) is arranged at such a great distance (a) below the upwardly terminating wall (13) of the air chamber (6) that, in the starting condition, the inlet and outlet opening (7) is permanently covered by the stationary water column located in the chamber (6) and, in the operating condition, the inlet and outlet opening (7) is permanently covered by the oscillating water column in the region of its upper turn-around point (b). In this manner, the entire quantity of the pulsed air is pressed out of the chamber into the outlet opening in a very advantageous manner by the water column oscillating upwards beyond the outlet opening and, as a result, a costly valve control system for maintaining a minimum level is no longer necessary since the pulsating water column in the air chamber takes over the function of a valve control system, specifically in that it periodically releases and closes again the inlet and outlet opening (7) of the air. <IMAGE>

Title: Cannula preventing after-bleeding
Inventor: WIEDEMEYER GEERT-LUTZ DR MED
IPC: A61M39/06
Filed: 1987-09-21
Abstract: The cannula preventing after-bleeding, NOSANG, is a cannula which has two attachments, one fixed and one rotatable, the fixed attachment having the eccentrically located cannula tube and the rotatable attachment having an eccentrically located opening. The two attachments are connected so as to be rotatable relative to one another via groove and tongue. By rotating the rotatable attachment with the inserted syringe tip the opening can be opened and closed. The advantage of this cannula preventing after-bleeding over conventional cannulas is the sealability and hence the prevention of emergence of blood from the cannula during blood sampling or repeated injections. The advantage over conventional closure mechanisms resides in the fact that the position of the cannula in the blood vessel is minimally changed by rotation of the syringe about the longitudinal axis. Moreover, the rotating movement with the syringe represents a physiological, that is, ergonomic, motion sequence. Thus, handling is excellent.

Patent DE-3804342-A1 (DE)
Title: Bicycle produced from die-cast light metal or injection-moulded thermoplastic
Inventor: KLAUE HERMANN DR ING
IPC: B62K19/16
Filed: 1988-02-12
Abstract: A description is given of a bicycle produced from die-cast light metal or injection-moulded thermoplastic, in the design of which the modulus of elasticity, which is lower than that of steel, is taken into account without the advantage of the considerably more favourable density being given up. Since, in this arrangement, consideration does not have to be given to profile dimensions, a greater inherent rigidity can be achieved than in the case of profile bicycles. The frame, which is cast in one piece, has a tubular main beam having an oval cross-section which is rigid in torsion and bending, which main beam runs into a bell-shaped steering head which encompasses the fork width and in which the likewise cast fork having a correspondingly dimensioned extension of conical tube cross-section engages, the fork foot being capable of being reinforced further by means of moulded-on headlight extensions. Furthermore, a description is given of a one-sided wheel suspension in which the wheels produced from a solid plastic disc are fastened by means of wheel bolts. The fork legs and rear-wheel carriers thereof are designed so as to be rigid in bending and torsion in that metal or thermoplastic plates are welded or adhesively bonded onto the moulded-on ribbing and the said plates form, completely or in part, the mud guards. As a result of this measure, the advantage results, for a one- or multi-stage cardan drive, that encapsulated spaces are formed between the moulded body and the plates, in which spaces the drive and the actuating parts are accommodated. <IMAGE>
