Patent CA-2039623-A1 (CA)
Title: Electric heater
Inventor: JACKSON BRIAN C
IPC: F24C15/22
Filed: 1991-04-03
Abstract: ABSTRACT            Electric Heater The heater is primarily intended for infra-red drying of travelling sheet material such as printed or lacquered paper.  Parallel elongate heating elements are contained in a housing having a front window and a rear openable cover carrying a ceramic reflector behind the heating elements , which reflector also serves to insulate the cover against heat from the elements.  End portions of the elements are supported in rearwardly directed clips whereby element removal and replacement can be readily effected at the rear of the housing.  The clips are carried by opposed support bars which with adjacent side walls of the housing define cooling air ducts, the bars having openings for directing cooling air onto the end portions of the elements or to enable the latter to extend into the ducts for direct cooling.   The front window is provided with air venting slots parallel with the heating elements and positioned opposite spaces between the latter.  The elements and slots are inclined to the direction of travel of the sheet material.

IPC: H04N5/14
Filed: 1991-07-11
Abstract: The present invention relates to apparatus for detecting the average picture level of an input image brilliance signal. The output of a first current mirroring circuit used as the load on a differential amplifying circuit, is fed into a smoothing circuit by a second current mirroring circuit.  As a result the direct current voltage of the output and the detection voltage amplitude can be set optionally without causing an offset voltage in the output average picture level voltage, the current flowing through the second current mirroring circuit being zero when APL = 0%.

Title: Data signal discrimination method and apparatus
Inventor: BECKER ANTHONY J
IPC: H04L27/02
Filed: 1990-02-22
Abstract: A method and apparatus for discriminating the data signal of a transmitter means. Binary encoded data is transmitted between a transmitter means and a receiver means in an amplitude modulated signal varying about a threshold level. A means and method are included for determining the number of threshold crossings of the carrier during each of a number of discrete successive time intervals (3). A further method and means characterizes those of said time intervals wherein the number of threshold crossings equals or exceeds a first predetermined number as a mark (5), and those of said time intervals wherein the number of threshold crossings does not exceed said predetermined number as a null (8). The number of successive marks not separated by a predetermined number of nulls is then counted by a further aspect of the method and means. A  series of successive marks in excess of a second predetermined number is then characterized as a one (11), and a series of successive marks in a range below said second predetermined number is characterized as a zero (12). The signal transmitted by said transmitter means is discriminated from interference by spurious signals.

Patent CA-2052603-A1 (CA)
IPC: E05B47/00
Filed: 1991-10-01
Abstract: A  lock monitor  is  provided  for  fitting  to lockable objects that have locks that incorporate a bolt mechanism including a slidable bolt having an engaging face at the free end thereof and a mortise.  The opening of the mortise is larger in at least one dimension than the engaging face of the slidable bolt. The lock monitor comprises an electrically operated status indicator, an actuating arm attachable to the engaging face of the slidable bolt, where the actuating arm extends generally perpendicular to the direction of movement of the slidable bolt, a contact plate attachable to the bolt mechanism adjacent to the engaging face of the slidable bolt, and first and second circuit contacts located on the contact plate. The first and second circuit contacts are connected in a circuit monitored by the status indicator, with the first and second circuit contacts being separated and insulated from each other such that the circuit remains open until the separation between the first and second circuit  contacts  is  bridged  by  engagement  with  the actuating arm when the slidable bolt is disengaged from the mortise. When the actuating arm engages the contact means it causes the status indicator to register a change in status in the lock.

Abstract: Two-channel forked light barrier in fail-safe construction IP 1002 / Hergiswil, 31 October 1990 Sg/tb Summary:        A two-channel forked light barrier in fail-safe construction for the production of a shaft information in the region of the storeys for the premature opening of the doors on arrival of the cage displays a cyclical dynamic self-monitoring (ZDU, 6), by means of which a prophxlactic.fault recognition.. is possible. The ZDU (6) on arrival and standstill of the cage at a storey periodically simulates genuine operational sequences in that a brief emergence of the switching vane is simulated by optical short-circuit of the FS light barrier. The thereby effected interruption of the relay feed is however shorter than the release time of the relays so that. these do not release when the circuit is intact. A sequential course of timing signals (tA/B1 to 4, tVB) controls the sequence of the self-monitoring functions. In the case of any kind of component faults, this run-down is disturbed and a corresponding reaction in the safety circuits of the lift control takes place by way of relay contacts. A cyclically appearing test signal (TSA, TSB) is the primary control signal for simulated interruptions.

Abstract: A screwdriver having a plurality of bits.  There is housing having a hollow interior to receive the bits. The housing has a handle and an open end, remote from the handle.  There is an internal column that is attached to the housing.  The internal column has a recessed end to receive a bit and prevents rotation of the bit relative to the housing.  There are openings around the housing extending longitudinally of the housing.  Each bit is operated by an actuator extending through an opening in the housing.  There is a leaf spring attached to the inner end of the actuator that receives a bit.  The bit may be moved from a position of storage within the handle by pressing a pre-selected actuator, moving the bit attachment out of the open end of the housing, holding the actuator down and retracting the bit to engage the recess of the column.  The guidance system is simpler than the prior art.  The handle is smaller than the prior art systems.  The mode of operation is simple.

Title: Method for producing rare earth magnet particles of improved coercivity
Inventor: KIM ANDREW S
IPC: B22F9/30
Filed: 1992-02-24
Abstract: ABSTRACT      A method for improving the magnetic properties, particularly intrinsic coercivity, of particles of a permanent magnet alloy comprising a rare earth element, iron and boron.  The method includes subjecting particles to a hydrogen atmosphere for a time at elevated temperature sufficient to hydride the particles.  The hydrogen atmosphere is removed while maintaining the particles at the elevated temperature.  Thereafter, while maintaining the particles at elevated temperature, the particles are subjected to a vacuum atmosphere for a time at the maintained elevated temperature sufficient to dehydride the particles.  Thereafter, while maintaining the particles at the elevated temperature, they are again subjected to a hydrogen atmosphere for a time at the maintained elevated temperature sufficient to hydride the particles.  The hydrogen atmosphere is removed while maintaining the particles at the elevated temperature.          Thereafter, the particles are subjected to a vacuum atmosphere for a time at the maintained elevated temperature sufficient to dehydride the particles.  The dehydrided particles are then cooled to room temperature.

Abstract: An image signal outline enhancing device to enhance the outline of the image formed by an image signal in digital form includes an interpolating circuit and an outline enhancing circuit.  An averaging circuit is provided for taking an average of two subsequently sampled digital data to produce averaged digital data.  A selector selects either of the digital data and the averaged digital data at every half period of the digital sampling interval to produce an interpolated image signal.  The averaged digital data is inserted between the two subsequently sampled digital data. As a result, the circuit can effectively enhance the outline of even a high frequency image signal whose leading or trailing-edge falls within a single digital sampling interval.
