Abstract: The present invention relates to a genetic engineering process for the optimal production and exposure to the immune system of additional antigen coded for by a live vaccine. The genetic engineering process is based on the use of spontaneous DNA reorganisation in the recombinant live vaccine, such that the recombinant live vaccine spontaneously divides into two subpopulations (A and B), whereby subpopulation A is capable of infecting and acts immunogenically per se as a minimum characteristic and subpopulation B as a minimum characteristic is regenerated by subpopulation A, produces additional antigen and acts immunogenically with respect to said additional antigen.

Abstract: In a vehicle seat having a backrest portion and a head support carried on the backrest portion by a connecting member, to reduce whiplash risk by forward displacement of the head support into a more effective head-supporting position, a displacement member is movably carried on the backrest portion of the seat. The displacement member has a sliding guide arrangement on which the head support connecting member is so guided that displacement of the displacement member in the transverse direction of the seat causes displacement of the head support forwardly of the seat. The displacement member is connected for displacement thereof to a resilient, mechanically stressable drive element activatable by a vehicle-specific acceleration sensor, for release and relief of the drive element to displace the head support.

Abstract: In a vehicle seat having a backrest portion and a head support carried on the backrest portion by a connecting device, to reduce whiplash risk by forward displacement of the head support into a more effective head-supporting position, a displacement device is linearly movably carried on the backrest portion of the seat. The displacement device has a sliding guide arrangement on which the head support connecting device is so guided that displacement of the displacement device in the transverse direction of the seat causes displacement of the head support forwardly of the seat. The displacement device is connected for displacement thereof to a pyrotechnic drive element on the backrest portion, with the drive element being activated by a vehicle-specific acceleration sensor.

Abstract: A mixing tool 10 can be mounted within a drum 20. A mixing arm 12 of the ing tool 10 can be held by a shaft borne in a rotatable fashion. A mixing body 11 is mounted to the mixing arm 12 and directed towards the inner surface of the drum. One or more rods 13 are introduced onto the outer surface 14 of the mixing body 11 and have a prominent mixing edge 18. A mixing tool of simple construction is developed with which nearly all mixable bulk products and/or product mixtures can be processed without leading to the formation of product deposits in the region between the inner surface of the drum and the mixing body 11.

Abstract: Communication system for vehicle wheel alignment apparatus includes transceivers for each wheel sensor and a plurality of transceivers disposed at a control console or control remote unit. Communication is accomplished with any particular sensor transceiver by switching among the control transceivers as follows: (1) If the sensor transceiver does not respond, switch the transmitter portions of the control transceivers sequentially until the sensor transceiver does respond, and (2) if the signal from the sensor transceiver is garbled, switch the receiver portions of the control transceivers sequentially until the message is ungarbled. The transmitter and receiver portions of the control transceivers are controlled independently, so that for a particular message transmission may use a first control transceiver and reception may use a second control transceiver.
