Patent CA-1301696-C (CA)
Title: Apparatus for distribution of logs into grinder supply shafts
Inventor: SILENIUS SEPPO
IPC: D21B1/20
Filed: 1988-05-04
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is disclosed for the distribution of logs into the supply shafts of a plurality of successive grinders from a conveyor line consisting of several belt, chain or other conveyors placed in succession and carrying the logs transversely thereon.  The logs are passed from one conveyor to the next and distributed into supply shafts through gaps between the conveyors, which are automatically started for moving the logs on the conveyor line so as to fill the supply shafts.  The equipment previously known and used for this purpose has several disadvantages, e.g. the need for sorting of the logs, unnecessary operation of the conveyors, overfilling of the line, etc.  The present invention obviates these drawbacks in that the line is provided with sensors for sensing the height of the stack of logs on the conveyor line above each grinder supply shaft, at least two sensors being located above the level of the conveyors so as to control the conveyors adjacent to the shaft, so that they will be started, in motion either simultaneously or separately towards the supply shaft therebetween to ensure that there is always a sufficient supply of logs at the grinder.

Abstract: Abstract Process for the preparation of binder dispersions capable of being cathodically deposited using crosslinking agents based on polyisocyanates blocked by hydroxyl groups The  invention relates  to  a process  for  the preparation of aqueous dispersions to be further proces-sed to electrocoating paints with baking temperatures below 160°C and baking times ? 30 minutes, which disper-sions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by hydroxyl groups as cross-linking agents.        In  this  process  polyepoxides  and  compounds containing one or more, preferably 2, hydroxyl groups per molecule are reacted at elevated temperatures in the presence  of  catalysts  to  furnish  epoxide-containing intermediates.        A solvent or a mixture of solvents is then added with external cooling and the solution is boiled under reflux, if necessary in vacuo, until the temperature of the solution drops to 95°C to 20°C.        Amines are then added onto the epoxide groups which are still present in a free state in the epoxy resin and a dispersion is prepared by adding a water/acid mixture  after  adding the  crosslinking  agent  or  the dispersion is first prepared and the crosslinking agent is added subsequently.

Granted: 1991-04-02
Abstract: 23                  54,18 ABSTRACT OF THE INVENTION           A method of assigning hall calls to a plurality of elevator cars in an ETA strategy in which up hall calls are scanned upwardly and down calls downwardly.  A hall call floor at which the scan has stopped for the purpose of assigning or reassigning a hall call at the floor is called a "scan floor".  The floor of the advanced position of the car being considered for assignment  is called the  "AVP floor".   In  order  to  favor  the  clustering  of  closely adjacent  stops  in a  given  car,  and  thus  minimize  car bunching, when a car has an intervening stop between the AVP floor and the scan floor,  either the travel distance between the AVP floor and the scan floor, or the travel distance from an intervening stop to the scan floor,  is used to develop a dynamic bias for the ETA of the associat-ed car.  The dynamic or variable bias is inversely propor-tional to the travel distance, i.e., the number of floors, between the relevant floors.

Abstract: SHUT-OFF VALVE                     ABSTRACT OF THE INVENTION     A plastic spring loaded shut-off valve for drains in live wells of boats  seals without  the presence of fluid pressure.           This effect is achieved by a biasing spring urging sealing flaps against the valve ports.   The flaps are curved and have ribbed edges  to  accomplish  such sealing  and prevent  jamming of  the ports.    The  biasing  spring  is  secured  to  a  rotating member through  slots  while  the  flaps  are  secured  to  the member by buttons.   The spring and flap are also secured by a bar across the flap, which has a bearing pad where it is contacted by the spring.  The rotating member is rotatable on the underside of the valve top screwed to the valve body.  Stops on the inside of the valve top limit its rotation.

Title: Single bus graphics data processing pipeline
Inventor: RADOCHONSKI PIERRE A
IPC: G06F9/44
Filed: 1989-08-17
Granted: 1994-05-10
Abstract: Abstract of the Disclosure Stages of a graphics data processing pipeline are interconnected by a common bus far conveying data and arbitration signals to and from each stage.  Each data transmitting stage arbitrates for and acquires control of the bus when it has output data to transmit to an addressable storage location within a next stage.  Each pipeline stage other than a first stage generates a BUSY bit indicating whether it is processing data or awaiting new input data from its preceding stage.  When one pipeline stage has output data to transmit to a next pipeline stage, the transmitting stage periodically polls the receiving stage by acquiring control of the bus and placing on the bus a particular address associated with the next stage.  Whenever the next stage detects the presence of the particular address on the bus, it places its BUSY bit on the data lines of the bus.  When the sending stage determines from the state of the BUSY bit that the next stage is ready to receive input data, the sending stage acquires control of the bus and sends the input data thereon to the next stage.

Abstract: COMBUSTION ENGINE WITH MULTI-FUEL CAPABILITY Abstract of the Disclosure A combustion engine has apparatus effective to provide a fuel mixture of one or more liquid fuels such as gasoline of variable aromatic content, normal alcohols, cosolvents, octane improvers and hydrocarbons having different energy contents in an unknown combination and combine it with air in a controlled A/F ratio with an input from a fuel mixture dielectric constant sensor.  The sensor comprises a capacitor in the fuel line near the engine so that the dielectric constant of the fuel mixture about to enter the engine determines the capacitance, a resistor in series with the capacitor, an oscillator providing an oscillating voltage across the resistor and capacitor at a high frequency of at least 1 MHz but less than a frequency requiring microwave components, and an electric circuit responsive to a capacitively determined electrical parameter of the capacitor such as the voltage thereacross to determine the capacitance thereof and therefore the dielectric constant of the fuel mixture. The high frequency of the circuit avoids problems of high conductivity in fuel mixtures having high alcohol concentrations which would short out the capacitor at lower frequencies and offers additional advantages over optical and microwave sensors.

Abstract: DEPLOYMENT/RETRIEVAL METHOD AND APPARATUS FOR WELL LOGGING      TOOLS USED WITH COILED TUBING                      ABSTRACT            A method of inserting a well tool for operating a coiled tubing which avoids the high and/or remote mounting of the heavy coiled tubing injector drive mechanism is disclosed.  The method comprises assembling the well tool within a closed end lubricator, mounting the lubricator or the wellhead and lowering the tool into the wellbore to a distance whereby at least a portion of the tool is adjacent the pipe rams of the wellhead.  The pipe rams are then closed against the tool to effect a fluid tight seal and to hold the tool in position within the wellhead.  The lubricator is then removed and the coiled tubing and injector drive mechanism are connected to the tool and wellhead, respectively.  The pipe rams can then be released and well logging or normal coiled tubing operations carried out.  The method offers the additional safety advantage of permitting pressure testing at each stage of the insertion process.  Retrieval of the tool can be effected merely be reversing the process.
