Title: Auxiliary drive for vehicle dynamo - utilises separate electric motor as power source when vehicle is stationary
Inventor: FISCHER HUBERT
IPC: H02J7/32
Filed: 1977-03-10
Abstract: The main purpose is to provide a means for charging the battery of a vehicle when it is stationary. The electric motor (2) is coupled to the dynamo (1) which is also driven from the vehicle engine through a clutch (4). The motor can be plugged in to the standard AC mains when the vehicle is in its depot. The dynamo therefore need only be rated to provide minimum necessary power when the vehicle is operating as any necessary additional battery charging takes place during the idle period. The smaller dynamo allows a reduction in overall space in the engine compartment which is not entirely absorbed by the addition of the motor as the latter is directly coupled to the dynamo and therefore runs at a high speed.

IPC: H04M9/10
Filed: 1977-03-30
Abstract: The telephone has a speech controlled speech direction recognition unit and reception and sending channel attenuation. A certain rest state of sender and receiver amplifier is determined by the speech channel damping controlled by the speech direction recognition unit. An automatic adjustment and comparator unit sets the sender side rest state in accordance with the incoming speech signal level tapped at the loudspeaker or receiver. This is done at high to medium speech level through the speeds direction recognition unit. It sets at the same time mean gain continuously adjusted by a hand operated variable resistor. At low signal level and, therefore, at high attenuation the receiving side rest level is adjusted through the speech direction recognition unit. It controls further the sensitivity of the speech channels whose attenuation and gain are set through the speech direction recognition unit in accordance with the set rest state.

Title: Tube for sepn. by centrifugation - is made of synthetic material and contains moving cylindrical separator preventing subsequent remixing
Inventor: BALLIES UWE DR MED
IPC: B01L3/14
Filed: 1977-08-02
Abstract: A tube for the sepn. by centrifuging of the heavier components from the lighter components of a liq. e.g. blood, and preventing subsequent mixing of the components, contains a cylindrical body, the density of which is between that of the components, and the external dia. of which is equal to the internal dia. of the tube. The tube is made of a synthetic material. During the centrifuging, the cylindrical body slides along the tube. The lighter component flows past it in the space formed between the body and the tube by the slight expansion of the tube, so that the body is always at the interface between the heavy and light phases. A suction piston may be attached to the cylindrical body and the tube may have a ferrule for an injection needle so that a sample can be drawn into the tube. The suction piston shaft is removed before centrifuging. Problems associated with excessive friction between glass tubes and plugs of elastomeric material, diffusion of mixt. through filter discs, and complicated methods of introducing the sample are avoided. The appts. is simple to make, e.g. by injection moulding. Mixing or diffusion of dissolved components is prevented, even during transport or prolonged storage. Filling is simpler, partic. when the appts. is used for sampling blood.
