Inventor: PARKHURST JOHN W
IPC: A01G23/087
Filed: 1994-01-28
Abstract: A high reach self centering hydraulic tree trimmer which consists of first a carriage assembly. The carriage assembly consisting of a top plate and a bottom plate. The plates are separated by spacers and secured together with a plurality of fasteners. A pair of cutting blades are contained between the top plate and the bottom plate. The blades are reciprocal of each other and each have a front end, center region, back end, outer edge, inner edge and a cutting edge extending along the inside edge. The blades are self centering about an object to be cut by pivoting independently from each other. They pivot about separate pivot points in the center region of the blades.  A pivot pin or bolt is used as a pivot device extending from the top plate to the bottom plate. A hydraulic cylinder is used to operate the blades. The hydraulic cylinder is pivotally attached to the back ends of the blades. This operation causes the blades to pivot independently about the pivot points resulting in the cutting surfaces closing upon each other. There is included an attachment means connected to the carriage assembly for attaching the tree trimmer to a bucket or other lifting means on a tractor or other such vehicle. There is also an optional positioning apparatus for pivoting the tree trimmer for cutting trees, branches, limbs or brush at different angles.

Title: Audio synthesizer time-sharing its first memory unit between two processors
Inventor: FURUHASHI MAKOTO
IPC: G10H7/02
Filed: 1994-10-25
Abstract: An apparatus for processing the speech information includes a first execution device and a second execution device for executing operations at respective different execution cycles, and a first memory unit for reading and recording the speech information. The first execution device and them second execution device exploit the first memory unit in common for processing the speech information. The processing apparatus further includes a second memory unit for storage of the speech information from the first execution means or the speech information read out from the first memory unit. The first execution device records the speech information on or reads the speech information from the second memory unit during the execution cycle of the first execution device. The second execution device accesses the first memory unit during the execution cycle of the second execution device for outputting the speech information to outside. The speech information recorded in the second memory unit is read out and recorded in the first memory unit or the speech information recorded in the first memory unit is read out recorded in the second memory unit during the time of not accessing the first memory unit. The data transfer between first execution device and the second memory can be performed during the execution cycle of the first execution device, while that between the second memory unit and the first memory unit can be performed during the execution cycle of the second execution device, so that it is possible for the first execution device to perform data transfer independently, such that sound source data can be transferred at a higher speed by employing a high-speed device as the first execution device.

Title: Multi-layered piezoelectric resonator for the separation of suspended particles
Inventor: TRAMPLER FELIX
IPC: B01J19/10
Filed: 1994-05-11
Abstract: Particulate material suspended in a fluid is separated and recycled by means of an ultrasonic resonance wave. In a preferred embodiment, the ultrasonic resonance field is generated within a multilayered composite resonator system including a transducer, the suspension and a mirror parallel to each other. Dimensions and frequencies resonant to the whole system but not exciting Eigen-frequencies of transducer and mirror itself are chosen so that thermal dissipation is minimized. Generally, the process is suitable for all kinds of particles (solid, liquid or gaseous disperse phases) especially for hydrosols (particles in water) and for separation of biological particles such as mammalian, bacterial and plant cells or aggregates.  Specialized applications in biotechnology are described including an acoustic filter for mammalian cell bioreactors or the selective retention of viable cells relative to non-viable cells.
