Abstract: It is an object of the present invention to provide a reduced fat butter which is butter-like without being cheese-spread like. In particular, the invention aims to provide a 55-65% butter-fat based spread with a butter-like texture using a simple process of low shear inversion. The additional problems faced include avoiding the high levels of caseinate previously found necessary for inversion and avoiding the costly 16 hr ripening step previously required. 
     A reduced fat butter which has a good butter-like texture by inversion of a concentrated cream in the form of a partially crystallised viscous paste. In particular, by phase inversion under conditions of low shear of a cream comprising from 55-65%wt butterfat and 35-45%wt of a gelled or thickened aqueous phase, wherein the cream is in the form of a partially crystallised viscous paste and wherein the C value of said paste at 20°C lies between 50 and 1500. Suitable aqueous phase thickeners are gelatine and caseinates. The viscosity of the aqueous phase should be such that at 20°C less than 20 ml of a 100 ml sample of the paste is discharged from a Ford viscosity cup type FB 11 having a fixed stainless steel nozzle (no 4.) in 2.5 minutes.

Abstract: The various information transmission systems provide the possibility for speech, image and text data communication between correspondingly equipped terminals, modern terminals exhibiting, as a rule, a microprocessor arranged in the terminal, which controls the various functions of the terminals and/or the exchange of switching information between terminal and exchanges of the information transmission system. If the subscriber device exhibits a combination of terminal devices, a change between services requires either a special construction of all terminals of the combination of devices or the change in service is carried out, for example, in central facilities of a specially designed private communication network. To provide for a rapid progress of the communication process, an indication of a message received at a terminal is automatically generated in the novel information transmission system and this indication and/or the message are transmitted to any subscriber device of the information transmission system. In this arrangement, the individual terminals of the combination of devices or the entire combination of devices can be connected to a main station line.

Abstract: A device for performing electroacoustic functions including noise cancellation, communication interface, and headphone functions. The device includes a composite transducer which is connected to a control unit. The composite transducer, which is adapted for use with the human ear, includes at least three transducers, oriented to be substantially coplanar to each other: two oppositely oriented input transducers for converting acoustic waves into electrical signals, and at least one output transducer oriented facing the ear for converting electrical signals into acoustic waves. The control unit includes circuitry for driving the output transducer based on electrical signals from the input transducers with an amplitude and phase to perform the noise cancellation, sound filtering, communication interface, and headphone functions. The input transducer which is oriented facing the ear picks up residual noise present in the ear canal which was not cancelled by the first input transducer to output transducer signal path due to non-ideal frequency and amplitude characteristics. The second input transducer supplies an electrical signal corresponding to the residual noise to the control circuitry to cancel the residual noise. Additionally, the path of acoustic energy from a noise source, through the composite transducer, and to the ear canal can be lengthened by the addition of a baffle around which the acoustic energy must travel.

Abstract: For transmitting data provided by track devices (G1) to passing vehicles, line conductors (L) of limited extent are connected to the track devices. The track devices are cyclically activated by a control station (LST). During this process, the control station transmits, for example, call-up messages for forwarding to the associated line conductor to the respective track device via a data line (K1). If these messages are received and acknowledged by a vehicle, this is detected by the control station which, by connecting a control code (+U) to the data line, causes the track device to output the data provided by the track device. The transmission process is ended by a second acknowledgement message. If the control station sends a continuous signal outside the times needed for calling up the vehicles and possibly the reception of acknowledgements, the vehicles can carry out a self-locating process in this time via the line conductors over which they run. The special advantage of the device according to the invention is that track devices of very simple construction can be used. <IMAGE>

Abstract: It is possible to limit the voltage across a diode to the level of the pinch-off voltage of a JFET in an integrated circuit in that the diode is connected in series with the JFET. As a result, the voltage offered through the JFET can be higher than the breakdown voltage of the diode, which is of particular importance in high-voltage ICs in which a highly doped buried zone is formed below the diode for reducing leakage currents to the substrate. According to the invention, the JFET together with at least one further circuit element is formed in a common island surrounded by an island insulation region. The gate of the JFET extends along the edge of the island and is separated from the relevant portion of the island insulation region substantially only by the source of the JFET. In the pinch-off condition, the gate divides the island into a high-voltage portion and a low-voltage portion which is coupled to the diode. The diode with the JFET occupies very little space and can be readily incorporated in integrated circuit designs.

Abstract: In an optical information recording-reproducing apparatus or method, a sum signal is generated from a divided sensor to be used for auto-focus (AF) and/or auto-tracking (AT) control. The AF servo is closed after an objective lens is moved to a location in the neighborhood of an in-focus position while working a position servo for an objective lens actuator using the sum signal. Further, the fact that a light spot is on a track is detected from the sum signal. If this fact is detected as well as the fact that a tracking error signal is in the neighborhood of zero, the AT servo is closed.
