Patent CA-2046791-A1 (CA)
Inventor: COY GERALD L
IPC: B65H7/08
Filed: 1991-07-11
Abstract: A method and apparatus for document feeding for improved operator document manual insertion in which a document may be manually initially inserted into a document input area and released. The document is sensed in the document input area by a document sensor, and then automatically clamped in a document feeding nip which is automatically actuated in response to the document sensing, and then the document is automatically fed. Here, a first time delay period is provided between the sensing of the manually inserted document and the automatic clamping of the document. A second time delay is provided between the automatic clamping and the automatic feeding of the document. Preferably the automatic clamping of the document in the feeding nip is with a limited initial nip force sufficiently low to allow manual document retraction without document damage during the second time delay period. Furthermore, preferably the document sensing automatically actuates an operator display, but here a substantial present time delay is provided between the sensing of the manually inserted document by the document sensor and the automatic actuation of the operator display.

Abstract: ABSTRACT OF THE DISCLOSURE          HARVESTING CROP FROM PARALLEL WINDROWS             A crop harvesting machine comprises a main frame attached  to a hitch of the type which pivots about a centre point  of  the main  frame.   On the main  frame  is attached a draper  frame  which  pivots  relative  to  the  main  frame  and includes arms extending downwardly and forwardly from the main frame for supporting a draper section which comprises a single draper  extending  across  the  full  width  of  the machine with rollers at the ends of the draper positioned directly at the ends  of  the  machine.    In  front  of the  single  draper  is positioned a pickup section pivotally mounted relative to the draper  frame and controlled  in height by guage wheels.   The width  of the  machine  is  sufficient  to  pickup  two  windrows simultaneously at fourteen foot spacings, to deposit the crop from the windrows simultaneously onto the draper and to move the crop to one end of the draper for deposit onto the ground.          This action provides a single windrow for subsequent collection by a baler in which the material which is previously been lying directly on the ground is now stacked upwardly from the ground for drying.

Abstract: Tensioning and lashing device for the stepwise tensioning and stepless release of lashing lines, consisting of a bracket (1), of a pivoting arm (2) and of a ratchet mechanism which is composed of ratchet wheels (3, 3') and blocking slides (5, 5'). Because a plurality of blocking slides (5, 5') is used, a higher lashing force can be absorbed or a stepwise tensioning of the lashing line in blocking-step sizes different from the tooth division t is possible. To release the lashing line, there is formed on the pivoting arm (2) a control cam (40) which brings the blocking slides (5, 5') into a disengaged position and consequently the ratchet mechanism into a release position. The use of curved blocking slides (5, 5'), of a curved driving slide (20) and of a leg spring (41) as a single spring element for the blocking slides (5, 5') allows a reduction in the constructional height of the device and has the effect of saving components and space. <IMAGE>

IPC: H04L25/52
Filed: 1992-03-16
Abstract: A repeater station comprises an RFD frame synchronization circuit, an AND gate, and an IFD frame synchronization circuit.  The RFD frame synchronization circuit outputs a frame synchronization signal indicating the timing of an auxiliary signal by performing frame synchronization with regard to the RFD. The AND gate inhibits clock signals during periods of the auxiliary signals and allows the clock signals to pass through during the other periods.  The IFD frame synchronization circuit performs frame synchronization of the RFD with regard to the IFD by carrying out frame synchronization operation in accordance with the clock signals output from the AND gate.  The IFD are accessible in the above simple construction.

Abstract: CONTINUOUS PREPARATION OF SECONDARY AMINES FROM NITRILES USING A COBALT/NICKEL/COPPER CATALYST                  (D#80,996-F) Abstract of the Disclosure A method for producing secondary amines, particularly fatty secondary amines such as ditallowamine from fatty nitriles, such as tallow nitrile over a cobalt catalyst promoted with copper and nickel has been discovered. The reaction gives high selectivity of secondary amine over the coproduced primary and tertiary amines. Additionally, the catalyst when supported on alumina, silica or a mixture of the two has good physical stability. The reaction may be conducted continuously in the presence of ammonia and hydrogen. The secondary amine proportion may be increased by a second stage using the same catalyst as the first stage, but in the absence of ammonia. The same catalyst may be used in both steps if a two stage continuous process is used.

Title: Power controller
Inventor: HATAKEYAMA NAOTO
IPC: H03G3/20
Filed: 1992-08-24
Abstract: According to this invention, a power controller includes a power amplifier, a detector, a digital/analog converter, and a power control unit.  The amplifier amplifies a high-frequency signal input on the basis of an applied control voltage to output a high-frequency power.  The detector detects the high-frequency power from the power amplifier to output a detection voltage.  The digital/analog converter converts externally input digital data into a reference voltage to output the reference voltage.  The power control unit compares the reference voltage from the digital/analog converter means with the detection voltage from the detector to output the control voltage.          The digital/analog converter has conversion characteristics in which a rate of change in reference voltage corresponding to a change in digital data is set to be low in a high sensitive output region of a feedback system constituted by the power amplifier, the detector, and the power control circuit and is set to be high in a low sensitive output region.

Title: Method and apparatus for reducing thermal stress on heat exchangers
Inventor: LYNCH GREGORY A
IPC: F23N5/20
Filed: 1992-08-26
Abstract: ABSTRACT The present invention is a furnace control system responsive to a circulator fan motor fault condition.  Upon detection of the fault, the control determines a first time period which is required to activate the temperature limit switch of the furnace by continuous operation of the gas burner and a second time period which is required for the plenum to dissipate sufficient heat to deactivate the temperature limit switch.  After determining the first and second time periods, the furnace control operates the burners for a fraction of the first time period and then allows the heat exchangers to cool for the second time period until the circulator fan motor fault is corrected or the demand for heat ceases.
