Patent CA-1313908-C (CA)
Title: Apparatus for manufacturing an optical transmission module
Inventor: SHIGA NOBUO
IPC: G02B6/42
Filed: 1989-08-28
Granted: 1993-02-23
Abstract: Abstract of the Disclosure A manufacturing apparatus comprises a heating device for heating a semiconductor laser in an optical transmission module package, a temperature sensor for measuring a temperature of the semiconductor laser, an optical power meter for measuring an optical output of the semiconductor laser, a manipulator for holding an optical fiber and positioning an end of the optical fiber to a desired position and a control unit for controlling the heating device and the manipulator.  The control unit reads data measured by the temperature sensor and the optical power meter and stores the data as a temperature-optical output characteristic of the semiconductor laser while drives the heating device.          The control unit also derives data of the optical output of the semiconductor laser produced through the optical fiber from time to time while solder is fused and solidified when the end of the optical fiber is soldered and fixed to the predetermined position in the package.          The measurement of the optical output is modified, in accordance with the temperature-optical output characteristic and the temperature of the semiconductor laser, and the manipulator is driven based on the modified measurement so that the position of the end of the optical fiber is finely adjusted.  In this manner, the optical fiber is fixed at a maximum light coupling efficiency position.

Title: Light emitting panel assemblies and method of making same
Inventor: PARKER JEFFREY R
IPC: A61B17/12
Filed: 1989-09-06
Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE           Light emitting panel assemblies and method of making same include one or more layers of woven fiber optic material having disruptions or bends at discrete locations along the length of the fibers to allow light to be emitted therefrom. Only selected areas of the disruptions or bends are coated with a suitable coating material that has a refractive index that changes the attenuation of the light emitted from the selected areas. The coating material may be applied to the selected areas using one or more carrier members which become part of the panel. Alternatively, a non-permanent carrier such as a roller may be used to coat selected areas of the optical fiber disruptions or bends with the coating material after the weaving process.

Abstract: ABSTRACT          VIDEO SIGNAL PROCESSING   A method and apparatus for keying TV signals.  A keying signal, K, is employed to create first and second modified keying signals, K(A) and K(B), which commence at independent points in time.  The modified signals are compared and, as a result, a revised keying signal, R, is produced commencing at the leading edge of one modified keying signal and terminating at the trailing edge of the other.  The operator selects R according to one of two rules (i),  (ii), the selection being by trial and error: rule (i): if K(A) > X(B) then R = K(A) if K(A) < K(B) then R = K(B) rule (ii) (which is the converse of rule (i)): if K(A) > K(B) then R = K(B) if K(A) < K(B) then R = K(A).          In this manner, the revised keying signal R can be made to coincide with the video signal, V, to be keyed.

Title: High pressure powder feed system
Inventor: SPAULDING MARK F
IPC: B05B12/08
Filed: 1989-09-15
Granted: 1993-11-23
Abstract: ABSTRACT OF THE DISCLOSURE            A system for feeding powder into high backpressure includes a carrier gas conduit with an orifice for entraining powder from a hopper, and a line for discharging feed gas at regulated pressure into the hopper to effect entrainment.  A gas bleeder line has an outlet connection to the output carrier conduit, with a line pressure representative of carrier pressure.  A differential pressure regulator responsive of the line pressure effects the regulated pressure equal to carrier pressure plus an increment.          A regulated relief valve in the input carrier gas conduit provides a bleed gas supply to the bleeder line at a pressure equal to carrier pressure plus an increment.  Pinch valves in the carrier conduit allow or prevent powder entrainments alternatively, a rotatable sleeve is on the carrier conduit with a side opening alignable with the entrainment orifice.  A carrier bypass conduit may be connected between the input conduit and the output conduit and hopper pressurization line may be connected between the output conduit and the hopper. An optional exhaust system may replace the bypass and pressurization lines and includes a differential exhaust valve to exhaust gas from the hopper when hopper pressure exceeds feed gas pressure.

Abstract: The invention concerns a method for using a telephone device MS in a telephone device system, in which the telephone device MS when it is ready to function receives a signal on the control channel CC1 from a base station BS1 and examines the signal quality. The telephone device MS completes the reception on the control channel CC1 and performs a channel search to find a new control channel, when a particular criterion is fulfilled for the worsening of the signal received on the control channel CC1. When ready to function, the telephone device MS is further controlled in response to a received electricity economising order to switch repeatedly into the electricity economising condition and terminate the signal reception for a particular time, and upon expiration of the particular time to switch for another time to a new electricity economising order to receive the signal on the previous control channel CC1. According to the invention, other criteria are stated for the worsening of the control signal received on the control channel CC1, which are fulfilled prior to the aforesaid criterion, wherein when the other criteria are fulfilled the telephone device MS is made to perform the channel search during the contemplated electricity economising time. When the electricity economising time expires, the telephone device switches to receive on the control channel CC1, unless a new control channel CC2 has been found. The telephone device MS performs the channel search on the basis of certain criteria periodically during the times devoted to electricity economising. As a result of this, the channel switching is smooth and easy. If the signal does not worsen continuously, the telephone device does not offer electricity economising time for channel search. The invention also specifies a telephone device to be used with the method according to the invention. <IMAGE>

Abstract: A connector for connecting lengths of metal tubing such as used for air-conditioning or central heating ducts, comprises a cylindrical end part for insertion into an open end of the tubing. In order to provide a seal between the connector and the tubing the connector has a recess containing a hollow, flexible sealing ring into which fluid can be injected to expand the ring. In order to ensure an adequate seal both before and after expansion of the sealing ring the latter has outwardly projecting sealing flanges which, before expansion of the sealing ring, make a seal due to their own inherent resilience and/or the resilience of the sealing ring, and, after expansion of the sealing ring, form a seal under compression. In one embodiment of the connector a sealing flange is adapted to fold over and lie between the respective faces of the connector and the tubing to prevent metal to metal contact between them.

Abstract: METHOD FOR CONTROLLING SEDIMENTATION       IN AN EBULLATED BED PROCESS        (D#79,086-F) ABSTRACT OF THE DISCLOSURE     In an ebullated bed process, it has been found that in switching from one sediment yielding feedstock to a second sediment yielding feedstock that the transient sediment concentration is 5 to 8 times the steady state concentration.      Such transients have caused unit shutdowns with lost production time.    A method has been found which avoids these high transient sediment concentrations.  Second feedstock is added incrementally (1 vol% to 2 vol% of the final rate) over the period of a week or more and sediment in the product analyzed.      After full second feedstock rate is achieved, first feedstock is reduced incrementally with sediment analysis.  Higher unit utilization is achieved with the corresponding increased yearly production.
