Patent CA-2014916-A1 (CA)
IPC: H04L27/16
Filed: 1990-04-19
Abstract: An FSK receiver includes first and second channel paths to which the received FSK signals are applied.  Each channel path includes a mixer circuit, a low-pass filter connected to the mixer circuit, and a limiting amplifier connected to the low-pass filter.   A voltage-controlled oscillator generates a local carrier and a phase shifter applies its output to the mixer circuits with a 90° phase difference therebetween.  A frequency detector is coupled to one of the limiting amplifiers for generating a signal representative of the deviation frequency minus the offset frequency of the received FSK signal.  An average circuit detects an average value of the signal from the frequency detector. A  comparator  circuit  detects  whether  the frequency representative signal lies in or outside of the neighbourhood of the average value.   A ramp voltage of constant amplitude is periodically generated if the signal is detected as  lying outside of the neighbourhood and maintained at an instantaneous value  if the signal  is detected as  lying in the neighbourhood.   The voltage-controlled oscillator is responsive to the ramp generator to control the frequency of the local carrier in search of the transmitted carrier frequency.

Title: Device on board a moving vehicle to obtain signals representative of the relative speed of the vehicle relative to an ambient fluid
Inventor: GARCIA JAMES
IPC: G01C21/10
Filed: 1990-06-22
Abstract: The device uses fringe laser diode anemometers which, from the beams coming from one or more laser diodes, for measuring volumes made of interference fringes. The component of the relative speed of an aircraft in a direction perpendicular to the plane of these fringes is deduced from the modulation that the dust particles cause in the signal of the photodetector of each anemometer during their passage in the measuring volume of this anemometer. By joining two anemometers with the measuring volumes whose planes of the fringes are, for example, orthogonal, it therefore is possible to determine two components of the relative speed vector and therefore to determine, for example, this relative speed in the longitudinal vertical plane of the aircraft, and to deduce from it the angle of incidence of the aircraft.

Filed: 1990-07-31
Abstract: A sleeve for storing and displaying a videocassette comprises a clear flexible plastic, elongated rectangular one-piece member, formed with an interior storage chamber completely enclosed except for an end opening through which a videocassette is inserted into and removed from the chamber. A chipboard cover having printed indicia thereon identifying a prerecorded program on the videocassette is retained within the chamber and slidably receives the videocassette therein. A pair of juxtaposed, elongated, preferably convex flanges, is formed on a spaced-apart pair of front and rear walls of the sleeve and extend partially across the end opening to retain the videocassette within the chipboard sleeve. Application of pressure by the thumb and finger of a user on spaced sidewalls of the sleeve adjacent to the end opening deforms the juxtaposed flanges to a parallel or concave configuration to enlarge the opening for removing the videocassette from the storage container for use, with the chipboard cover remaining in the storage chamber for subsequent removal at a later date in a nondeformed condition.

Title: Expression vectors that produce steroid receptors, steroid receptor chimera, screening assays for steroid receptors and clinical assays using synthesized receptors and receptor vector
Inventor: MCDONNELL DONALD P
IPC: C12Q1/68
Filed: 1991-01-15
Abstract: Abstract The present invention relates to a method for making an expression vector which produces a biological active receptor.  The method includes synthesizing a linker having the carboxyl six amino acids of ubiquitin and an internal restriction site and cloning the synthesized linker to form a plasmid.  The plasmid is then digested with a restriction endonuclease which is compatible with the internal restriction site in the synthesized linker.  After the digestion of the plasmid a cDNA coding for the receptor is inserted into the compatible restriction site and the plasmid is then used to transform yeast.  In the procedure, the yeast that is usually used is from the strains of Saccharomyce and Aspergillus.  In addition, numerous vectors which express the human vitamin D receptor, human androgen receptor, human progesterone receptor, thyroid receptor, retinoic acid receptor, chicken progesterone receptor, chicken vitamin D receptor, rat vitamin D receptor and COUP protein are described.  A further aspect of the invention is the reporter vector which includes the proximal promoter element of the yeast iso-l-cytochrome C and a structural gene selected from E. coli either the ?-Galactosidase gene or the Galactokinase gene. The reporter vector is used to detect for agonist and antagonists for the steroid hormone receptor.   A further element of the invention is a chimera made up of the DNA binding domain from one receptor and the hormone binding domain from another receptor.  The chimera is used in an assay to identify the function of the unknown receptor component.  Additional aspects are clinical and laboratory assays for biological compounds using the receptors synthesized from the expression vectors and using receptor vectors.

Title: Tube fabrication with reusable mandrel
Inventor: SIEMERS PAUL A
IPC: B22F3/115
Filed: 1991-03-14
Abstract: RD-20,403 TUBE FABRICATION WITH REUSABLE MANDREL                 ABSTRACT OF THE DISCLOSURE         A method for forming a multiplicity of ring struc-tures having essentially the same internal diameter is taught.  A first step in the process is the provision of a mandrel of relatively high thermal coefficient of expansion and the deposit of a layer of unreactive oxide on the surface of the mandrel.  Following the oxide coating of the mandrel surface, a layer of a matrix metal is deposited thereon to form a ring structure on the nandrel  The coefficient of thermal expansion of the mandrel metal and that of the matrix metal are sufficiently distinct that there is a spontaneous separation of the deposited matrix metal ring structure as the mandrel and deposited layer cool to room temperature. Following the cooling, the matrix metal ring structure can be removed from the mandrel and the mandrel is then rendered suitable for repetition of the process to deposit yet another matrix ring structure thereon.

Abstract: The present invention is based on the discovery that a cured organic or organosiloxane gel will enter and flow through a conduit to a dispensing location as a coherent, homogeneous portion of material when 1) one end of the conduit is immersed in the gel, 2) a sufficient pressure differential is applied between the surface of the gel and the interior of the conduit to cause the gel to enter and at least partially fill a portion of the conduit, and 3) sufficient pressure is then applied within the conduit to cause the gel to flow in the conduit to at least one dispensing location where the gel is withdrawn from the conduit as an integral, homogeneous stream of material.

Title: Motor control apparatus and method
Inventor: MINNICH THOMAS
IPC: H02P6/06
Filed: 1991-08-02
Abstract: An apparatus and method for controlling brushless DC motors are provided.  Velocity loop control is performed digitally to produce current commands at a high frequency loop closure interval.  Commutation of field coil current is controlled in response  to  current  commutation  pattern  control  signals produced in response to measured relative position of the motor rotor and motor stator and a velocity average over a number of loop closure intervals.  Switch control signals to control transistor switches providing current from a DC power source to the motor terminals are produced in response to the current commands, measured motor current and the commutation pattern control signals.  The velocity loop control implements a selected transfer function relating velocity, the motor torque constant, and the moment of inertia of the motor and associated load.   Facilities are provided for periodically adjusting velocity loop transfer function gain factors and the effective moment of inertia in response to input signals. Additionally, current loop amplification gain factors and time constants are made selectable by input signals.
