Patent CA-2037951-A1 (CA)
Title: Telephone test instrument
Inventor: HILLIGOSS WILLAM R
IPC: H04M3/30
Filed: 1991-03-11
Abstract: Abstract of the Disclosure A telephone test instrument permits voice communications with and monitoring of a telephone circuit to be tested.          The instrument includes a microprocessor used in controlling various functions of the instrument.  The microprocessor and other circuits of the instrument are energized from a con-nected telephone circuit and/or an internal energy supply which is automatically recharged from the telephone circuit.          The microprocessor continually checks the voltage of the internal  energy  supply  and  automatically  turns  off  a loudspeaker of the instrument,  or prevents it from being turned on, if the voltage is too low.  The instrument inclu-des circuitry which, in combination with the microprocessor, measures loop current or line voltage while the instrument is  connected  for  making  voice communications  with  the telephone circuit.  When the loudspeaker within the instru-ment is energized, the earpiece receiver remains active.  A belt hook connected to a housing of the instrument can con-nect an electrical ground through a switch in the instrument to the telephone circuit for providing a ground start.  The instrument also includes a "crow-bar" circuit which effec-tively  open-circuits  the  instrument  from  a  connected telephone circuit if too high of a loop current flows.

IPC: H04N7/00
Filed: 1991-07-18
Abstract: On the transmission side, a delay unit, an adder, and a subtracter obtain an interframe sum output by calculating, in units of two frames, an interframe average sum of progressive scanning signals each having N scanning lines [per frame], and an interframe dif-ference output by calculating, in units of two frames, an interframe average difference related to moving image data.  The interframe sum output is band-limited to a band which can be transmitted with a conventional scheme by switching, time expansion, vertical filtering, and first scanning line count conversion, and converted into M scanning lines [per frame].  The interframe difference output is band-limited to a band effective for resolu-tion improvement of a moving image in a receiver of a conventional scheme by switching, time expansion, vertical filtering, horizontal filtering, and second scanning line count conversion, and converted into M scanning lines [per frame].  Outputs obtained by first and second scanning line count conversions are input to a sum arithmetic means to generate a first frame signal, and input to a difference arithmetic means to generate a second frame signal.  The first and second frame signals are transmitted as an interlace scanning signal of M scanning lines [per frame] for a central portion thereof.

Title: Self regulating connecting device containing fusible material
Inventor: MCGAFFIGAN THOMAS H
IPC: H02G1/14
Filed: 1991-10-18
Abstract: Abstract of the Invention In accordance with the present invention, a heater element which includes a layer of ferromagnetic material (14) is included in a connecting device along with a fusible material such as a solder preform (10). The connecting device includes, for example, a hollow sleeve (4) formed of heat shrinkable material.  The solder preform (10), the heater element and the heat shrinkable hollow sleeve (4) are integrally formed as a self-contained solder sleeve device such that the heater element is separate from the objects to be joined and does not completely shield to generation of an inductive current in the objects to be joined.  The connecting device thus promotes even flow and bonding of the fusible material around a junction between the objects.  Further, a connecting device is provided which permits visual inspection of a connection between objects bonded upon activation of the connecting device, thus providing an opportunity to confirm the integrity of the junction.

Title: Apparatus for electrophoretic application of a lacquer onto plate-shaped work pieces
Inventor: HOSTEN DANIEL
IPC: C23G3/00
Filed: 1992-06-19
Abstract: ABSTRACT OF THE DISCLOSURE    For the electrophoretic application of a lacquer onto plate-shaped work pieces, the work pieces are conveyed on a horizontal throughput path through a cell wherein a lacquer deposition bath and at least one electrode are situated.  The anodic or cathodic contacting of the traversing work pieces occurs via an endlessly circulating contacting drive preferably formed by a metal band and via a contact element arranged outside the cell for the feed of the anode current or cathode current to the contacting drive.   The lacquer deposited on the contacting drive in the cell is in turn removed via a cleaning arrangement outside the cell and, thus, a reliable  contacting  of  the work pieces  is  guaranteed.    The apparatus  is  particularly  suitable  for  the  electrophoretic application of etching resists, plating resists and solder resists onto printed circuit boards.

Abstract: ABSTRACT          A device is provided for regulating the tension on shoelaces of the type worn in conventional footwear.  The shoelace tension regulating device is mounted on the top of the shoe with which it is used, preferably by lacing the shoelace ends through a pair of apertures in the housing of the device.  The shoelace ends which emanate from the uppermost eyelets of the shoe adjacent the wearers ankle are not tied, as in conventional practice, but are captured by a hook mechanism that is wound onto a drum within the device by means of a crank in the form of a rotatable cap.  The drum is carried in rotation as the cap is turned until the desired level of tension on the shoelace ends has been achieved.  A pawl and ratchet wheel in the device prevent counter-rotation until the user desires to release tension on the shoelace ends, at which time the pawl can be disengaged from the ratchet wheel by an actuating mechanism operable externally of the device.  An internal helically wound band spring interposed between the drum and the crank permits slight reciprocal movement of the shoelace ends to avoid excessive tension when the footwear upper is severely flexed, and to also avoid excessively reduced tension when the users foot is relaxed.
