Title: Ultrasonic log grading
Inventor: MACK MICHAEL J
IPC: G06Q10/04
Filed: 1992-02-14
Abstract: ULTRASONIC LOG GRADING                ABSTRACT OF THE INVENTION         A log harvesting system is disclosed in which the log is graded automatically in the field by ultrasonic testing of the log.  Pulses of ultrasonic waves are transmitted into the log to detect internal defects within the log by measuring changes in the transient time of the ultrasonic wave pulses through at least a portion of the log.  A computer is used to determine the grade of the log and produce a grade output signal from transient time data and signals related to the length and diameter of the log. The log is marked with a different colored paint to indicate its grade by an automatic marking device in response to the receipt of the grade output signal. Ultrasonic testing apparatus may be added to a tree harvesting head with a saw for felling the tree and cutting the log to the proper length and delimber knives for removing limbs, in order to test the log for defects as the log is conveyed through such head.  In one embodiment, a pair of ultrasonic transducer wheels are mounted on opposite sides of the log and pairs of transmitting and receiving transducers are selectively coupled to the log through liquid coupling chambers provided on the outer surface of such wheels as the wheels rotate along the length of the log.

Title: Side entry mixer apparatus
Inventor: HOWK RICHARD A
IPC: B01F27/71
Filed: 1992-03-23
Abstract: SIDE ENTRY MIXER APPARATUS                         Abstract Side entering mixer apparatus has an impeller with an axis of rotation above and along the bottom of a tank in which the material (liquid or liquid suspension) to be mixed is disposed.  In a discharge region in front of the impeller and in close proximity to the front of the impeller, there is disposed a flow straightening vane which removes substantially any radial component of flow.          By removal of the radial flow component, helical flows which interact in the discharge region and cause pulsation of flow into the inlet region (between the rear surface of the impeller and the side wall of the tank from which it projects) are substantially eliminated and potentially catastrophic stress-induced failures in the side entering mixer and its seals are avoided.

Title: Dynamic shift control for an automatic transmission
Inventor: KOENIG MELISSA M
IPC: B60W40/09
Filed: 1992-07-07
Abstract: An improved control, which dynamically adjusts the shift control parameters in response to the driving habits of the operator, as judged by an indication of the average peak acceleration during specified operation of the vehicle.  To determine the indication of average peak acceleration, the longitudinal acceleration of the vehicle is continuously determined in the course of vehicle operation.  The peak acceleration values occurring in successive ratio-dependent time intervals are identified and accumulated to form cumulative and average peak acceleration terms.  The average peak acceleration term is used to form a dynamic shift factor which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a continuum of shift control parameters uniquely suited to the driving style of the operator of the vehicle.

Title: Mass addition detector
Inventor: EDWARDS DAVID G
IPC: B60R25/10
Filed: 1991-10-30
Abstract: The mass addition detector is particularly suitable for use with vehicles. The detector senses change in mass using a combination of one or more load sensors (21) adapted to detect small changes in the mass of a stationary vehicle, discrimination means adapted to discriminate between long term and short term changes and alarm means adapted to provide an indication of any long term mass changes. Preferably, the or each load sensor (21) is attached within the body of the vehicle, for instance by association with the suspension system (23). In one form at least one load sensor (21) is associated with a spring suspension system (23) and senses relative movement between the vehicle body (24) and the spring (23). In an alternative form the load sensor is located on a surface of a resilient mounting bush (22) mechanically joining the spring and the vehicle body. The load sensor may be provided with sensor control means to engage and disengage the sensor from the suspension system. The preferred load sensor is a strain gauge. The discrimination means is a microprocessor programmed to analyse the signals and programmed to analyse the signals so that when a mass change exceeds a predetermined magnitude and lasts for a predetermined time period an alarm signal is produced.

Inventor: FITCH FRANK
IPC: A61F11/04
Filed: 1991-11-28
Abstract: 2096974 9209251 PCTABS00013 A communication device (10) for transmitting audio information to a user and a transducer (28) therefor are provided. The device includes processing circuitry within a compact housing (16) for converting input audio signals into transducer driving signals. A  miniaturized microphone (20) is mounted on the housing for receiving the input audio signals. The input audio signals are then amplified and filtered to appropriate signal levels by the processing circuitry. Once the input audio signals have been processed in this manner they are applied to a driver which outputs transducer driving signals analogous to the input audio signals. The transducer driving signals are received by a transducer assembly (14) worn by a user and energize a pair of coils (72) located on opposite sides of an armature (73) forming part of the transducer assembly. The electromagnetic forces generated by the coils when energized cause the armature to move which in turn drives a plunger (46) so that the plunger moves in a vibrational pattern analogous to the input audio signals. The plunger contacts the skin of the user so that the vibrational pattern is received by cutaneous nerve receptors on the user's body or by the user's ears via bone conduction and is then transmitted to the user's brain for processing. A pair of springs (70) are located on opposite sides of the armature (73) and bias the armature and plunger (46) so that they move to a datum in the absence of driving signals and oppose their movement when driven by the coils (72).

Abstract: Fresh squeezed single-strength citrus juice or other juices are homogenized under an ultra-high pressure of about 15,000 psi.  Surprisingly, the ultra-high pressure homogenized juice exhibits an increased shelf life and decreased microbiological activity compared to juice homogenized under conventional pressures.  The microbiological activity present in the juice is significantly reduced despite the fact that no pasteurization step is conducted.  Single-strength juice processed in this manner maintains good flavor and palatability for 40 days at a storage temperature of 40°F or lower compared to less than one-half this shelf life for untreated juice.
