Title: Sealer mechanism for a tool for applying a seal to overlapping lengths of strap
Inventor: ANGAROLA BARRY R
IPC: B65B13/34
Filed: 1991-12-24
Abstract: IMPROVED SEALER MECHANISM FOR A TOOL FOR APPLYING A SEAL TO OVERLAPPING LENGTHS OF STRAP                   ABSTRACT OF THE DISCLOSURE         A method and apparatus are provided for applying a fold-over seal about overlapping lengths of strap.  The open seal is positioned with the strap lengths between the legs.  opposing jaws are pivoted about axes against the open seal legs toward the strap lengths to bend the seal legs inwardly while decreasing the distance between the seal and the pivot axes of the jaws.  The decrease in the distance between the jaw pivot axes and the seal is limited at a predetermined minimum distance, but the jaws continue to be pivoted to fold the seal legs adjacent the strap lengths.  As the jaws approach the fully closed position, the distance between the seal and the jaw pivot axes is increased, and this forces the seal crown and legs closer together as the crimping of the seal is completed.

Abstract: A linear  compensating  circuit   is  provided  which comprises a first level detection circuit for detecting the level  of an input  signal to  an amplifier,  a second level detection  circuit  for  detecting  the level  of  an output signal from the amplifier, an amplitude compensating circuit for  controlling  the  amplitude  of  the  input  signal  in accordance  with the  difference  between  the  signal level detected by the first detection circuit and the signal level detected by the second level detection circuit for improving the  linearity of  an  input-output  characteristic  of  the amplifier,  and a phase compensating circuit for controlling the  phase of the input signal in accordance with the signal level detected by the second detection circuit.  This linear compensating circuit performs the compensations of amplitude and  phase  and  as a result, the degradation  of  phase characteristic  induced due to the compensation of amplitude can be prevented, resulting in a reduction in the distortion of an output signal  of the amplifier  even when it is being operated  in the vicinity  of the  saturation  range.  This linear compensating circuit is effective when applied to a power amplifier,   particularly to  a  high  frequency  power amplifier. It has a characteristic set preferably to cancel the phase change of  the output signal induced caused by the compensation of  amplitude  by  the  amplitude  compensating circuit.          .PA

Patent CA-2083536-A1 (CA)
Inventor: DURTLER WILLEM G
IPC: H04B1/04
Filed: 1992-11-23
Abstract: ABSTRACT OF THE DISCLOSURE An automatic bias control ("ABC") circuit reduces the source current, e.g., collector-bias current, drawn by a power amplifier in order to minimize power consumption, without significantly affecting the amplifier's gain.  The ABC circuit accomplishes this by regulating the control current supplied to a power amplifier in response to a sensor signal indicative of the amplitude of the source signal and a computer-controlled reference signal.  The invention can be practiced advantageously in a terminal amplifier of a transmitter of a dual-mode mobile cellular radio-telephone.  The sensor signal is used to take into account variations in the collector-bias current required to achieve a pre-determined amplifier gain under, for example, changing ambient (e.g., temperature) conditions.  The reference signal is used to indicate, e.g., the mode of operation of the radio-telephone (i.e., whether digital or analog), the mode of operation of the amplifier (i.e., whether linear or non-linear), and the power level of the radio-frequency signal being supplied to the power amplifier.  Accordingly, in each case, the bias currents can be set to lower values than in conventional linear amplifiers used in digital radio-telephones or non-linear amplifiers used in analog radio-telephones operating under the same conditions, thereby reducing power consumption.

Title: Adjustable Shin Pad
Inventor: HOSHIZAKI T BLAINE
IPC: A63B71/12
Filed: 1992-12-02
Abstract: A shin pad is described in which the shin shield is in two pieces, namely an upper piece which is secured to the lining of the knee cap, or to the knee cap itself, and a lower piece which is slidable up and down relative to the upper piece, and to which a lower liner is secured, the lower liner being independent of the knee liner.  Preferably, the lower piece is slidable with respect to the upper piece by virtue of one or more slotted holes in either or both of the upper piece and/or lower piece, with bolts and T-nuts being used in the slots to secure the pieces together in the desired position. Preferably, there are three such slotted holes, namely a front central one and two side ones, namely one towards either side of the pad.  Preferably, there is sufficient sloppiness in the slots to provide a varus/valgus adjustment, i.e. an adjustment of the angle of the shin shield, in the vertical lateral plane, relative to the orientation of the knee cap, by permitting the lower piece to be secured with one side higher than the other relative to the upper piece.

Inventor: KROGSTAD IVAR
IPC: B63B27/24
Filed: 1992-04-24
Abstract: The invention relates to a suspension device for an oil conveying pipe or hose for loading or unloading of a vessel.  The device is cardanic, and during unloading the oil is conducted towards the cardan centre from one or both sides along a horizontal axis through one or more pipe swivels and possibly also bearings.  Thereafter, the oil flow is diverted and is conducted back towards the cardan centre along the second cardan axis.  After having passed the next pipe swivel the oil flow is diverted to the third cardan axis, and in order to relieve this pipe swivel bearings may be arranged coaxially with the pipe swivel.  The pipe bend is in this case suspended in brackets attached to a cylindrical load cell, which in turn pivots in a beam structure which is an integral part of the pipe structure and which pivots about the first cardan axis.  The load cell is able to register the hose tension.

Abstract: Abstract of the Disclosure A control system and method permit simultaneous automatic and manual control of a device  (e.g.,  a valve or valve actuator) for changing a parameter of a system, such as the fluid level in a tub of fracturing fluid used to fracture an oil or gas well.   Rather than providing a control signal representing an integration of the parameter,  the present invention provides a control signal representing only an error or change so that integration occurs mechanically in the device for changing the parameter.  This allows the mechanical integration to be manually overridden without disrupting the automatic control which is concerned only with the resultant error or change and not the total integration.
