Patent CA-2082148-A1 (CA)
Title: Device and method for controlling the contrast in an image observation system provided with an mcp image intensifier
Inventor: SCHELEN JOHANNES B J
IPC: H05G1/64
Filed: 1991-04-17
Abstract: An image observation system comprises an image intensifier provided with an MCP. It further comprises an image converter to convert the output image of the image intensifier into a video signal or a visible image. When the contrast range in the image formed by the image converter is large the voltage applied across the MCP  is increased and the gain of the image converter is reduced. When the contrast range in the image formed by the image converter is small the voltage applied across the MCP is reduced and the gain of the image converter is increased. In this way the contrast in the image is controlled by the darker portions of the observed scene instead of by the brighter portions.

Title: Blood cell analyzer
Inventor: BACUS JAMES W
IPC: G01N15/14
Filed: 1992-11-25
Abstract: ABSTRACT OF THE DISCLOSURE              A method and apparatus for automatically analyzing red blood cells in a blood cell sample stained to enhance selected constituents of the blood cell sample.  In particular, red blood cells are analyzed to determine how many of the red blood cells contain RNA and can therefore be categorized as reticulocytes.  The number of red blood cells  and  the number of  reticulocytes  are  counted to determine the percentage of reticulocytes in the blood cell sample.    This  percentage  is  used  as  one  measurable indication of the composition of the blood sample and the health of the blood donor.  In addition, other attributes of the red blood cells are determined,  including cell shape, pallor, and hemoglobin content.  These attributes in combination with the reticulocyte percentage combines to give a complete picture of the health of the blood and consequently the blood donor.

Inventor: VON KALER ROLAND L
IPC: F16H63/32
Filed: 1993-02-09
Abstract: A front shift arrangement for transaxles of small tractors and riding lawn mowers.  In one embodiment, the shifter is a cylindrical rod having arms engaging the shift collar of an in-line transmission.  one end of the shifter extends out the front of the transaxle housing and has a square head with a bore for attaching to a lever and linkage.  By moving the lever and thereby pivoting the shifter, the shift collar is axially moved to selectively engage gears gear ratios of the transmission, with the shifter being releasably secured in selected positions by a detent biasing mechanism.  The shifter is positioned below the central plane of the transaxle in the lower housing by a cover plate.  The lever attached to the shifter moves on a vertical arc to pivot the shifter.  In a second embodiment, the shifter is a flat piece which is bent to form an arm and a lever portion.  The arm portion extends out an opening in the lower housing and is bent to form the lever portion which may be attached to and moved by linkage to an operator lever.  A bushing pivotally supports the shifter in the opening and includes a detent biasing  mechanism for releasably securing the shifter at positions which correspond to the gear ratios.  A wall of the housing is positioned in front of the recesses to retain the bushing within the housing.

Title: Method for treating aqueous solution containing fine particles
Inventor: SU QINGQUAN
IPC: C02F1/28
Filed: 1992-09-29
Abstract: Abstract There is provided a method of treating aqueous solution containing fine particles to separate and recover fine particles, and clean the aqueous solution in a simple manner.  Mineral absorbent comprizing SiO2 by 35-65 wt% and the rest being one or more than one oxides selected from MgO, CaO, Al203 and FeO is used.  Aqueous solution after being adjusted its pH to be less than 9 is made to pass through the packed layer of absorbent where above explained absorbent is packed therein.  In the aqueous solution having a pH of less than 9, the absorbent is positively charged whereas most fine particles are negatively charged so that fine particles tend to adhere to the absorbent due to the electric attracting force existing between them.  When a descaling solution having a pH greater than 10 is brought into contact with a absorbent where fine particles have been adhered as a results of the preceeding treatment, both of the fine particles and absorbent become negatively charged and the fine particles is removed from the absorbent in to the descaling solution due to the electric repelling force existing between them.

Inventor: KOGURE MITSUHIRO
IPC: H01H11/04
Filed: 1993-04-30
Abstract: The capability of heat dissipation from the contact surface of a magnetic switch for a starter motor is improved without increasing the fabrication cost.  A punch 28 having a plurality of square projections arranged in two mutually perpendicular directions at the pitch of P is applied to the surface of a plate member 27 to form a first group of punched recesses 29a.  The pitch P is twice the length of a side of each punched recess 29a.  Then, the punch 28 is shifted with respect to the first group of punched recesses 29 by P/2 in both the vertical and horizontal directions before forming a second group of punched recesses 29b.  The punched recesses 29a and 29b define projections 26 in the parts which are not occupied by these recesses generally in the pattern of a checker board.  Because the projections 26 are separated from each other, and can effectively dissipate heat therefrom, the increase in the contact resistance due to heat generation can be prevented, and the efficiency of the starter motor can he increased by using a punching process which is both simple and economical.

Abstract: ABSTRACT An improved process for producing nitrogen-based atmospheres suitable for annealing ferrous metals and alloys, brazing metals, sintering metal and ceramic powders, and sealing glass to metals from non-cryogenically generated nitrogen is presented. These atmospheres are produced by 1) humidifying non-cryogenically generated nitrogen containing less than 5.0 vol.% residual oxygen, 2) mixing it with a specified amount of a hydrocarbon gas, 3) feeding the gaseous mixture into the heating zone of a furnace through a diffuser, and 4) converting in-situ the residual oxygen and moisture present in it to a mixture of carbon dioxide, carbon monoxide, moisture, and/or hydrogen. The key features of the present invention include a) humidifying the feed gas prior to introducing it into the heating zone of a furnace operated above about 800°C and b) using enough amount of a hydrocarbon gas to facilitate in-situ conversion of residual oxygen and moisture present in the feed gas to a mixture of carbon dioxide, carbon monoxide, moisture, and hydrogen in the heating zone of a furnace.
Patent CA-2112166-A1 (CA)
Inventor: GOODWIN R WENDELL
IPC: G01D5/36
Filed: 1993-12-22
Abstract: An optical sensor for monitoring position of a movable object comprising a LED and a phototransistor is provided with control circuitry, which is responsive to an output signal generated by the phototransistor for causing the LED to suspend radiation of light.      When the light reflected from a reflective area of the object falls on the phototransistor, the control circuitry turns off the LED as soon as the output of the phototransistor goes below a threshold level signifying that the phototransistor has been turned on.      When the light is absorbed by a non-reflective area of the object and the phototransistor is not turned on, the control circuitry turns off the LED after a predetermined time period, which is chosen to be slightly larger than the response time of the phototransistor.

Filed: 1994-05-09
Abstract: A moving slide has a pair of flexible curtains mounted to its front and rear surfaces, the curtains being attached at opposite ends to front and rear support posts mounted to a base.   The support posts have upper and lower pulleys.  A cable is connected to the front of the slide and runs in this fashion:  first horizontally across the top pulley, thence to the lower pulley, thence to the other support post, thence upwardly and finally around to the horizontal portion which connects to the rear of the slide.  The cable is tensioned to a predetermined load which remains constant throughout the slide travel as the front and rear horizontal portions of the cable move.  The flexible curtains are suspended from, but are not rigidly attached to, the cable.  Thus, as the curtains expand and contract, the moving horizontal portions of the tensioned cable ride smoothly through the curtains, maintaining curtain support.
