Title: Auger bin check
Inventor: STOIAN DAN
IPC: G01F23/00
Filed: 1993-08-31
Abstract: ABSTRACT A grain level checking apparatus is used with a grain auger. It includes a filament that extends the length of the auger and is supported in guide tubes attached to the auger tube. At the upper end of the auger, the filament is attached to a weight, while at the lower end a length of the filament is wound on the spool. When the filament is released from the spool, the weight will draw the filament down into a grain bin being filled until the weight reaches the grain. At that point, the amount of travel of the filament along the auger tube can be determined and used as a direct measure of the height of grain in the bin.

Title: Enhancing the storage stability of organic phosphites and phosphonites
Inventor: QUOTSCHALLA UDO
IPC: C07D241/04
Filed: 1993-10-01
Abstract: Abstract Enhancing the storage stability of organic phosphites and phosphonites The invention relates to a process for stabilizing an organic phosphite or phosphonite or a mixture of organic phosphites or phosphonites against hydrolysis, which comprises adding, as the stabilizer, a compound from the class of sterically hindered amines, so that the stabilized phosphite or phosphonite contains 0.1 to 25% by weight of the amine compound (relative to the phosphite or phosphonite).   Compositions comprising organic phosphite or phosphonite and sterically hindered amines are notable for excellent hydrolytic stability and have a long shelf life even at high atmospheric humidity.   The products of the process according to the invention are very useful as stabilizers for organic material, in particular organic polymers, for example synthetic polymers, against the damaging influence of heat, oxygen and/or light.

Title: Method and apparatus for accurately estimating a clock frequency and for simulating a precision clock oscillator
Inventor: RIFE DAVID C
IPC: H04L7/027
Filed: 1994-01-27
Abstract: "METHOD AND APPARATUS FOR ACCURATELY ESTIMATING A CLOCK FREQUENCY AND FOR SIMULATING A PRECISION CLOCK OSCILLATOR"                 Abstract of the Disclosure A method for estimating the frequency of the symbol clock in an incoming signal so as to match the frequency of the local symbol clock to the frequency of the remote symbol clock. An analog front end (15) samples an incoming signal to provide a sampled signal. A frequency estimator and clock recovery circuit (16) recovers the symbol clock in the incoming signal and performs a Discrete Time Fourier Transform (DTFT) at two frequencies, F1 and F2. The amplitude of the DTFT at F1 is compared with the amplitude of the DTFT at F2 to provide an estimate of the frequency of the symbol clock in the incoming signal. A master clock (20) provides a clock signal to a clock adjustment circuit (23), which divides the clock signal to provide the transmitter symbol clock for the modem (10). The estimate of the frequency of the symbol clock in the incoming signal is used to adjust the divide ratio in the clock adjustment circuit (23) so that the frequency of the transmitter symbol clock of the modem (10) matches the frequency of the symbol clock of the incoming signal.          The present invention matches these frequencies within 10 parts per million (ppm). Therefore, a precision symbol clock can be generated using a master clock having an accuracy of only 100 ppm.

Title: Bumper mounted anti-tip stabilizers for chair-mounting vehicles utilized by physically disadvantaged persons and others desiring mobility assistance, and methods of stabilizing such vehicles
Inventor: BUSSINGER ALLEN L
IPC: A61G5/10
Filed: 1994-06-02
Abstract: ABSTRACT OF THE INVENTION         A vehicle for physically disadvantaged persons and others desiring assistance which carries a chair at a relatively high level, is supported by wheels on front and rear axles.  It has a rear bumper, supported by the frame and consisting of side attaching elements connected by a bumper cross element.  Pivotally connected to each bumper side element is an anti-tip wheel support leg which mounts an anti-tip wheel having an axle connected to the lower end of each leg such that the legs are gravity biased to swing in toward the bumper.  The wheel-supporting legs support the anti-tip wheels at a predetermined vertical distance above the ground when the frame is traveling over level ground, and are operative to automatically swing rearwardly away from the rear wheels to cause the anti-tip wheels to engage the ground and stabilize the vehicle from further tilting, when the frame tilts upwardly a predetermined amount from front to rear.
Patent CA-2125980-A1 (CA)
Title: A method for coating particles in a spray-drying plant
Inventor: HOLM CHRISTENSEN BORGE
IPC: A23K20/20
Filed: 1992-12-17
Abstract: A free-flowing powder of coated particles is produced by means of a spray drying plant using a hot drying gas or a spray cooling plant using cold drying gas. A coating composition in liquid form is supplied to the atomizing means of the plant, and the liquid coating composition is atomized into a flow of liquid droplets, which are allowed to collide with particles of a carrier material dispersed in a transport gas. The direction and rate of flow of the transport gas are adapted to prevent contact between the drying gas and the droplets, so that the liquid coating composition, before any substantial drying thereof, will form a continuous liquid coating layer on the particles. The thus applied continuous coating layer on the particles is then allowed to at least partially dry by contact with the drying gas before withdrawal of the coated particles from the spray-drying chamber of the plant to a moving bed in the form of loose agglomerates. Suitable coating compositions are fat-containing emulsions containing proteins.

IPC: D21J1/00
Filed: 1993-03-09
Abstract: In a process for making board according to the wet method, a stock is prepared from fibres produced from a fibrous raw material, and a binder is added prior to dewatering and pressing. The process is distinguished by adding the binder to the fibres before the preparation of the stock. The binder may be a water-soluble binder which is precipitated and fixed to the fibres by acidification.  Acidification may take place in connection with the preparation of the stock or prior thereto as well as prior to the addition of the binder.

Title: Formulations, method and apparatus for the controlled generation of phosphine
Inventor: WATERFORD COLIN J
IPC: A01N25/04
Filed: 1993-06-04
Abstract: A formulation for use in the controlled generation of phosphide comprises an intimate mixture of a particulate phosphide and a water-immiscible compound, the mixture having the consistency of an extrudable paste or a thick slurry. The phosphide, which is preferably aluminium phosphide or magnesium phosphide, comprises from 65 to 85 per cent (by weight) of the formulation. The water-immiscible compound is preferably paraffin oil, petroleum jelly, or mixture of these materials. A surfactant may be included in the formulation. Such a formulation (21, 41) can be held in a cartridge (20, 40) and added progressively to water (13, 33) in a reaction chamber (10, 30). Alternatively, the formulation can be packaged in a water-impermeable container from which a region can be removed to expose the formulation to water vapour in a gas flowing past the container. The water (13, 33) or the water vapour removes or diffuses through the water-immiscible compound from the formulation, then reacts with the phosphide to form phosphine. The phosphine, mixed with a carrier gas (usually air), may be fed into a duct (15, 55, 66) connected to a grain silo, for fumigation of grain stored in the silo.

Inventor: ETTEL VICTOR A
IPC: H02J7/00
Filed: 1993-07-14
Abstract: A battery charger is provided which automatically controls the charging process independent of individual battery con struction or temperature. Control of the charging process is achieved by periodically interrupting the charging current, determin-ing resistance-free voltage of the battery in fixed intervals after interruptions of current, and comparing the resistance-free voltage with a reference voltage. Reference voltage is automatically determined for each recharging subject by analyzing the change in re-sistance-free voltage with respect to time during an initial, constant current period to locate certain characteristic points indicative of the onset of overcharge. The charging current is reduced as necessary, so that the resistance free voltage does not exceed the reference voltage and significant overcharge is avoided.
