Title: Improved environmental stress crack resistance of hips
Inventor: NKE-AKA BRENDA C
IPC: C08L51/04
Filed: 1995-01-20
Abstract: High impact polystyrene (HIPS) and other impact modified styrenic polymers such as ABS and MBS tend to suffer from environmental stress cracking. On extended exposure to oily or fatty substances the plastic tends to craze, then crack and finally break. Unfortunately, a number of applications for impact modified polymers is in areas where there is a high potential to contact with oily or fatty substances. The environmental stress crack resistance (ESCR) of impact modified styrenic polymers may be increased by increasing the particle size of the impact modifier and including a low molecular weight polybutene.

Inventor: WHITE JAMES F
IPC: G05B19/042
Filed: 1995-01-25
Abstract: A system for monitoring and/or controlling operation of a machine is particularly designed for agricultural machines such as seeders or planters. Thesystem includes a central monitor unit and a plurality of sensors all connected in series on a communication bus. Each sensor is manufactured with a unique ID code. The central monitor unit on installation of the system polls each sensor as it is installed in a particular order of installation determined by the central monitor so that central monitor knows the location, function of each sensor in conjunction with its ID code. The central monitor then controls polling of the sensors by commands addressed to the individual sensors. Each sensor has a processor, transducer and a memory for storing data arising from the transducer. The memory can comprise a rollover memory of a simple nature which counts pulses or clock pulses and transmits the stored data when polled by the central monitor.

Patent CA-2148577-A1 (CA)
Title: Method for myoelectric control of an artificial limb
Inventor: GAMMER PETER
IPC: A61F2/72
Filed: 1995-05-03
Abstract: For myoelectric proportional control of an electric-motor-powered artificial limb, either proportional speed regulation or proportional gripping force regulation is performed. In proportional speed regulation, the set rpm value is determined from various rpm setpoints. The rpm setpoint is compared with the actual measured rpm of the motor and fed to a proportional-integral (PI) regulator as a system deviation. In the PI regulator, the system deviation is converted into a pulse-width-modulation (PWM) signal and the drive motor is then controlled at an rpm proportional to the actual electrode voltage. The actual current value of the drive motor is measured and compared with a set current maximum which, when exceeded, causes the PI regulator to be switched off. In proportional gripping force regulation, the maximum gripping force is divided into stages, with the actual electrode voltage corresponding to a certain number of stages. Each stage is associated with a pulse-width- modulation (PWM) value and a current shutoff value. Counting takes place from 0 to the number of stages specified by the current electrode voltage. Each PWM value is output with the equivalent current shutoff value. At the same time, the drive motor current is measured and compared with the outputted current shutoff value. When this shutoff value is reached, the counter is increased by 1 and the next PWM value is output. When the counter reaches the number of stages defined by the actual electrode voltage, the set gripping force is reached and the drive motor is shutoff. The current value of the drive motor is measured and compared with a set current maximum which when exceeded, causes the drive motor to shutoff.

Title: Method and apparatus for reducing noise generated by combustion
Inventor: SOUTHALL LESLIE ROY
IPC: F23R3/28
Filed: 1995-05-24
Abstract: A combustor in which fuel is introduced into a combustion zone at a first acute angle with respect to the radially outward direction so as to swirl the fuel about the combustor axis, thereby improving the stability of the combustion process.  Combustion air is introduced into the combustion zone at a second acute angle with respect to the radially inward direction so as to swirl the air about the combustor axis in the same circumferential direction that the fuel is swirled, with the first and second acute angles being approximately equal.  By swirling the combustion air in a manner that is compatible with the swirling of the fuel, noise associated with the combustion process is reduced.

IPC: B31B50/10
Filed: 1995-06-06
Abstract: A forming roller or a supporting roller for a packaging material web used for a liquid container according to the present invention comprises a plurality of rollers with outer peripheral surface thereof curved in axial direction of a rotating shaft, and said plurality of rollers are arranged at positions for forming a planar packaging material web into tubular shape or at positions for supporting the packaging material web after it has been formed into tubular shape. Each roller is divided into a plurality of roller portions by planes perpendicular to a rotating shaft thereof. The packaging material web is passed between said plurality of rollers, and the surface of the packaging material web is brought into contact with outer peripheral surface of said plurality of rollers.      When said packaging material web is transported, each of the divided roller portions of the rollers is independently rotated. In this case, the roller portion having a smaller diameter is more quickly rotated than the roller portion with a larger diameter, and there will be no big difference in peripheral speed between the outer peripheral surfaces of the rollers. As a result, resistance of the rollers to the packaging material web is reduced, and the packaging material web is passed more smoothly.

Abstract: A sensitive assay method has been discovered that reduces the amount of non-specific binding present in an assay, the method comprising detecting an analyte present in a sample through a specific binding reaction in which either an analogue of the analyte or a specific binding partner of the analyte is immobilized on a solid-phase and said specific binding reaction produces a detectable product immobilized on said solid-phase that may be correlated to the amount of analyte present in the sample wherein said assay employs an effective amount of a surfactant selected from the group consisting of a polyoxyethylene-alkylether, a polyalkylene oxide-modified polydimethylsiloxane block copolymer, a polyalkylene oxide-modified polymethylsiloxane block copolymer, and mixtures thereof to reduce non-specific binding.
Patent CA-2154008-A1 (CA)
Inventor: ONYSZKANYCZ PIOTR
IPC: G10D13/00
Filed: 1995-10-06
Abstract: Disclosed is an actuator for a percussion instrument, such as a bass drum. The actuator includes a heel driven member, which handles the vertical motion of a free falling leg, and, through the motion transmitting lever, which ends with a sound initiation member, transforms it onto the bass drum face until the heel driven member reaches a blocking surface  of the actuator's base. The user can initiate the percussion instrument by letting his leg to fall down from a raised position while keeping the foot toe in one place on the base. The heel driven member, after it reaches the base, is blocked, what prevents from hitting the drum face with unneces-sary big force and allows to control the dynamic of play so it does not increasetempo. The motion transmitting lever converts a vertical motion into a horizontal one as well as regulates the  maximum  deflection of the beater into the bass drum face and by this means controls the dynamic of play. The actuator also allows tofilter weak shots, which for some reason may not be desired.

Abstract: An anchoring cartridge for a hardening multi-component composition on the basis of a resin hardening by the reaction of radicals has an inner cartridge element containing the resin component and fillers and an outer cartridge element containing the hardener component.  To allow the anchoring rod to be put in position by hand by driving the anchoring rod in fully, without spurting out or running out occurring during the operation of putting the rod in position, and to enable fillers to be used in both components to increase the strength, the inside width of the annular space between the inner and outer cartridge elements corresponds  at least to the wall thickness of a cartridge element and at most to 5% of the external diameter of the outer cartridge element.  Further, the resin contains a thixotropic agent which increases the viscosity of the resin to such an extent that the filler parts are suspended in the resin.  The hardener component, which is present with liquid and optionally fillers and a thixotropic agent as a pasty mixture, completely fills the annular space between the inner and outer cartridge elements.
