Granted: 1985-09-28
Abstract: A rotary rock bit is described having a plurality of legs extending downwardly from the main bit body. Each leg further includes an inwardly extending journal pin for rotatively supporting a cone-type cutter. An annular thrust member is provided for axially retaining the cutter onto the journal pin. In one embodiment the thrust member is adapted to extend into an annular groove formed in the journal pin with the other radial surface thereof engaging an inner annular surface of the cutter. The radial surface of the thrust member is then welded to cutter by an electron beam process. An access aperture is provided in the journal pin and leg to enable the electron beam to pass therethrough and strike the thrust member and cutter. During this operation, the cutter is rotated along with the thrust member across the access aperture to create a 360 DEG  weld therebetween. In another embodiment, an annular groove is formed in the cutter cavity for receiving the thrust member. An access hole is formed in the cutter to enable the electron beam to pass therethrough and strike the engaging surfaces of the thrust member and journal pin. Similarly, relative rotational movement of the components enables a 360 DEG  weld to be created.

Abstract: The material for extraction is extracted with physiologically acceptable fat or fat-like solvents in the presence of water. This is carried out in a closed pressure vessel at elevated temperature. The amount of water must be such that the water activity corresponds to a aw value of not less than 0.5. By suitable choice of the aw value it is possible to control the process in such a way that the flavour develops in the direction of a boiled flavour or in the direction of a roast flavour. The resulting flavour concentrate can be used as a semi-finished product in the manufacture of sauces, soups, seasoning mixes and the like or can be sold as a finished product. The material which has been subjected to the extraction process is in general completely tasteless.

Abstract: A digital wireless subscriber telephone unit for wireless connection with a base station. The subscriber unit has a baseband processor which is coupled to storage device for the baseband functions. The baseband processor is direct access coupled to a modem processor whereby the two processors may communicate with each other. The modem processor generally acts as the master in the system, although lock-out circuit may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified. The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal. On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode. In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with a looped-back signal to produce correction constants to compensate for undesirable variations in the IF, these constants being stored for use in correcting actual received signals. During demodulation, the modulated digital signals are fed to the modem processor in the form of time multiplexed I and Q samples and are demultiplexed. The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.
