Title: Ripper assembly with pitch control and integral frame and push block
Inventor: STEPE VISVALDIS A
IPC: A01B13/08
Filed: 1991-02-04
Abstract: When a ripper assembly incorporates an adjustable pitch control and has a push block, the visibility of the ripper tip by the operator is many times limited or totally lost. In this subject arrangement, a push block (52) is integral with a frame assembly (14) and a ripper carriage assembly (16) is pivotally secured to the frame assembly (14). By the push block (52) being integral with the frame assembly (14), the ripper carriage assembly (16) is simple and compact allowing better visibility by the operator to the rear of the ripper assembly (10). Furthermore, a sight opening (46) is defined in the frame assembly (14) immediately in front of the ripper carriage assembly (16) so that the operator has a clear visibility of the area around the ripper shank (70) and/or the ripper tip (72) when the ripper tip is not engaged in the ground.  The better visibility to the rear of the ripper assembly (10) is enhanced by having first and second pitch control cylinders (98, 100) universally secured to the ripper carriage assembly (16) generally adjacent thereto.

Title: Multiple adapter response detection circuit
Inventor: GIBBONS JOHN C
IPC: G05B19/05
Filed: 1992-01-31
Abstract: Abstract of the Disclosure An adapter response circuit indicates the number of adapters on a link responding to a given address and hence permits the detection of possible data collisions.  Each adapter responding to the address transmitted on the link induces a current on a common conductor.  The magnitude of the current unambiguously identifies the number of adapters responding to that address.  The proper resistive termination of the link may be checked by inducing a similar incremental current on the conductor and evaluating a voltage variation indicating the presence or absence of a termination resistor.
Patent CA-2060899-A1 (CA)
Inventor: JARVENKYLA JYRI
IPC: B29C48/13
Filed: 1990-07-05
Abstract: This invention relates to an apparatus for manufacturing ribbed pipes. The central axis of the apparatus has a core (8, 9, 10) about which a material in a plastic state is extruded through a nozzle (11). The end of the core has a kernel (10) of a substan-tially constant diameter which calibrates the inner surface of the pipe. The outer surface of the pipe acquires its form from axially moving moulds (1, 2). The kernel has a heated initial zone and a cooled end zone (14, 15). In known apparatus, the grooves (13) of the moulds are often incompletely filled and the inner surface of the pipe is made uneven. These drawbacks can be avoided by disposing a cooled widening end face (20) at the outset of the end zone (15) of the kernel.

Abstract: In order to reduce the number of update operations for determining LPC (viz., reflection) data from an incoming sampled data, a plurality of matrices representative of autocorrelation functions are set in memory. Subsequently, data representative of the upper triangular portions of the matrices (virtual upper triangular matrices) are extracted from the memory and arranged into an array. This array is then updated using a j-th reflection coefficient, after which the value of j is incremented and the updating is repeated until a predetermined number of updating is completed.

Title: Transmembrane pressure controlled filtration system
Inventor: HOOD ROBERT G
IPC: A61M1/36
Filed: 1990-10-16
Abstract: A fluid flow control apparatus is described in which a removable sterilisable or disposable element is provided and in which the pressure of the fluid inlet and fluid outlet of the filter unit are monitored and the pressures are compared and used to control the pressure across the filter unit. This is particularly suitable for cross-flow filtration which is a procedure whereby the process fluid is recirculated over the membrane surface. Pressure is measured by bleeding the inlet conduit through an inlet bleed conduit (62) which includes a pressure switch (67) and pressure transducer (65). The outlet conduit containing the retentate also has a bleed line (78) and a post-membrane pressure transducer (84) is inserted in the second bleed off line. With this arrangement the inlet and outlet pressures can be monitored and the pressure values are averaged in use to control the pressure switch or valve so as to maintain optimal control of the transmembrane pressure and optimise filtration for the particular fluids and membranes used.

Filed: 1993-01-27
Abstract: ABSTRACT OF THE DISCLOSURE   For manufacturing a pulse generator wherein a voltage pulse dependent on the change in magnetic field can be achieved by sudden magnetic reversal (Barkhausen skip) given an applied magnetic field, an iron alloy is employed for one of the materials of the composite member, the additional alloy constituents of this iron alloy being selected such that a structural conversion with volume change respectively occurs at different temperatures. For producing the stressed condition, a thermal treatment is then implemented, which includes heating above the upper transition temperature and a cooling below the lower transition temperature. As a result, substantially greater stresses between the materials of the composite member arise, causing a pulse behavior significantly improved in comparison to known pulse generators of the type capable of recognizing constant or alternating magnetic fields.

Filed: 1993-03-31
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a method for specular polishing the surface of a metal or non-metal plate to be polished, especially a large-sized plate, in which the surface of a plate to be plated is polished by rotating a polishing member via cranks, while pressing the polishing member against the surface of the plate at a predetermined pressure.  Since the polishing member is rotated via cranks, while being pressed against the surface of the plate at a predetermined pressure, the predetermined pressure is uniformly distributed over the entire surface to be polished, hence, precise and uniform specular polishing of even a large-sized plate is feasible.
