Title: Gland pressure seal plate
Inventor: DOROW JAMES WALTER
IPC: F16J15/44
Filed: 1990-10-31
Abstract: ABSTRACT OF THE DISCLOSURE     A steam turbine gland seal arrangement for use  in a steam turbine which has at least one casing  and  a shaft  extending through the casing so that steam  may be  admitted into the casing for operating  on  blades attached to the shaft for effecting rotation  thereof. An inner gland and an outer gland are provided at  one end  of  the shaft where the shaft exits  the  casing. Each of these glands support seals in close  proximity with the shaft for preventing steam from escaping  the casing.   The  inner  gland  is  supported  within  an aperture in the casing where the shaft exits,  and the outer  gland  is attached to an outer surface  of  the casing surrounding the aperture.  An outer cylindrical surface of the inner gland, coaxial with and  radially spaced   from   an  inner  surface  of   the   casing, circumscribes  the aperture.  An annular finger  seal, positioned  between  the casing and the  inner  gland, prevents  leakage of steam onto the outer gland.   The arrangement  further  includes an annular  seal  plate which circumscribes the turbine shaft and has an inner radial  portion  attached to an outer surface  of  the inner  gland.  An outer radial portion of the  annular seal  plate  is cantilevered from the  inner  attached portion.  The outer radial portion contacts an axially inner  surface of the outer gland when this  gland  is attached  to  the casing. The outer  gland  exerts  a deflecting  pressure  on  the annular  seal  plate  to provide a positive seal between the inner  gland  and the outer gland.
Patent CA-2030948-A1 (CA)
Inventor: KEEGAN RICHARD G
IPC: G01S1/00
Filed: 1990-11-27
Abstract: A demodulation frequency plan for use in a global positioning system (GPS) receiver, having three demodulation stages for L1 and L2 signal channels, in which identical local oscillator frequencies are used in the L1 and L2 channels at each demodulation stage, to minimize phase error differences between the two channels. The third stage provides an output at an intermediate frequency high enough to carry the full information bandwidth, thereby simplifying digital sampling of the signal, which is also performed in the third stage.      Sampling is performed at a high enough rate to facilitate subsequent conversion to baseband. Moreover, the sampling rate is a binary multiple of the intermediate frequency, and this binary relationship further simplifies conversion to baseband.

Title: Method and apparatus for investigating and controlling an object
Inventor: MARUHASHI FUMIO
IPC: C12N5/071
Filed: 1991-07-25
Abstract: In order to investigate an object, such as a culture of micro-organisms, the object is repeatedly investigated at two different magnifications by an image pick-up device.  The images at the two different magnifications are then analysed by an image recognition device and the results of the repeated analysis are compared whereby to derive a measurement of a change in the object with time.  For a culture of micro-organisms, the number of cells can be determined at one magnification and the number of microscopic spherical bodies can be determined at another magnification, to obtain a measure of the activity of the culture.  Preferably, one or more conditions of the object are then controlled on the basis of the measurement of change.

Patent CA-2059875-A1 (CA)
Title: Electronic biopsy instrument
Inventor: MALLABY MARK
IPC: A61B10/02
Filed: 1992-01-23
Abstract: ABSTRACT OF THE DISCLOSURE   An instrument for removing tissue samples from a tissue mass which automatically penetrates, severs, and removes a tissue portion for examination.  The instrument is motor powered, preferably by self-contained rechargeable batteries, and employs electrically actuated stops to control the action of penetration into and retraction from the tissue mass.  The tissue penetrating means and severing means includes an inner stylet which penetrates the tissue mass and a hollow outer tube or cannula which surrounds the stylet and serves to sever a sample of tissue.  In a preferred form the tissue penetrating end of the stylet is notched so that when the stylet penetrates the tissue mass, a portion of the tissue relaxes in the notched area.  After tissue penetration by the stylet, the cannula, having a cutting surface at its distal end, penetrates the tissue and cuts off the tissue portion residing in the notched area of the stylet.  The tissue penetrating and severing means are operably connected to a motor powered rotary cam assembly by means of cam followers and the rotary motion of the cam is converted to sequential, linear motion in the tissue penetrating means and severing means.  The angular position of a cam is monitored with a pair of optoelectronic sensors, thereby providing position feedback without mechanical wear on the position sensor assembly.  Improved action is provided by a cam having an S-curve profile.

Abstract: FISHING GAME APPARATUS               Abstract of the Disclosure A fishing device or apparatus wherein a plurality of flat vertical objects resembling fish are arranged in a horizontal row along a horizontal support.  Each fish is provided with a mouth and a slot which connects with a circular opening below the mouth.  For the purpose of catching the fish,  the would-be fisherman,  or player, will utilize a casting rod with a winding reel.  The end of the line which connects with the fishing rod and the reel, however, will be provided with a plug which cooperates with the circular opening below the mouth of the fish.  The plug is made of resilient material, such as rubber or plastic, and is provided with a nose piece adjacent the connection of the line to the plug.  This nose piece is tapered from a diameter of smaller size than the circular opening in the fish to a diameter slightly larger than the diameter in the opening.  Immediately beyond the larger diameter of the nose piece, the plug is provided with a recess so that when the plug is pulled into the opening, the nose piece will squeeze through the opening until the sides of the opening are lodged in the recess.          Further pulling on the line will pull the fish off the horizontal support and the fish is now "caught".

Title: Video camera, video camera device and adopter used therewith
Inventor: HASHIMOTO HIROYUKI
IPC: H04N5/235
Filed: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE     Techniques of video cameras or the like which may be effectively used with photo-camera, for instance, are disclosed.  In response to the detection of a greater image pick-up signal level change than a predetermined extent, a shutter pulse is generated.  In addition, in response to the shutter button operation, the blanking area of image is increased or reduced to provide a special effect of indicating the shutter operation.  The output signal of an optical sensor having the same characteristic as the image pick-up device is integrated, and when the integral signal exceeds a predetermined value, the AGC circuit gain is reduced to a predetermined extent to prevent the image pick-up signal level from being excessively increased.    Further, when the integral signal exceeds a predetermined value, a read pulse is supplied to the image pick-up device, thus permitting charge accumulation time increase in the image pick-up device to increase the sensitivity without leading to saturation of the charge accumulation.

Title: Audience participation system
Inventor: CALDWELL FRANK
IPC: H04M3/56
Filed: 1992-06-25
Abstract: Abstract An apparatus and method for allowing an audience to communicate with a speaker.  The apparatus comprises hand-held modules that are given to members of an audience and a base station which is located near the speaker.  The audience modules contain means for entering a response such as a keyboard or barcode reader to respond to a query by the speaker.  These modules then transmit upon cue from the base station not only the response but also a unique identification number associated with the module.  The responses are collected by the base station and processed by a personal computer having statistical analysis software contained therein.  The aggregate response of the audience is then statistically analyzed including an analysis of the identity or characteristics of the individuals giving particular responses by association with a dossier contained within the memory of the personal computer.  In one embodiment of the invention the base station is capable of transmitting and the audience modules are capable of receiving data which may be individually tailored to subgroups or individual members of the audience.
