Title: Probe assembly for infrared thermometer
Inventor: SUSZYNSKI EDWARD D
IPC: G01J5/02
Filed: 1989-10-23
Granted: 1996-11-12
Abstract: A probe assembly for an infrared medical thermometer, which is adapted for insertion into a patient's ear canal and which facilitates a rapid measurement of the patient's body temperature with very high accuracy. The probe includes a plastic outer tube sized to fit snugly in the patient's ear canal, with an elongated heat sink and an infrared sensor located within the tube. A cylindrical shield and inwardly-projecting guard ring ensure that the sensor's hot junction receives radiation only from the ear canal and that the sensor's cold junction is prevented from being heated for at least sufficient time to allow the thermometer to provide an accurate measurement of the patient's body temperature.

Patent CA-2037706-C (CA)
Inventor: FOSSUM GORDON C
IPC: G06T15/40
Filed: 1991-03-07
Granted: 1995-12-12
Abstract: A  system  and  method  are  provided  for  use  in conjunction with a computer graphics system such that a single pass,  or set of operations can be used to draw specific  polygons  contained  within  an  image  being displayed.   The  computer  graphics  system  includes  a multiple bit frame buffer, a write mask which can disable at least two bits of the frame buffer, a z-buffer capable of being turned off and a color map which is loaded with a background,  a visible line and a hidden line color. With the z-buffer turned off, and the first bit plane of the frame buffer enabled and the second bit plane of the frame buffer disabled by the write mask, the hidden line color is selected from color map 10 and draws the polygon being considered with the selected color.  The z-buffer is then turned on and with one bit plane disabled and another  bit  plane  enabled  by  the  write  mask,  the background color is selected from the color map.   The polygon interior is then drawn with the background color previously selected, however any pixels corresponding to previously drawn  lines  will  not be painted with the background color because of the disablement of bit plane one.  The visible line color is then selected from the color map and the polygon being considered is drawn. With the z-buffer turned on, any visible lines will take precedence over corresponding hidden lines or background colors having corresponding pixels.  The next polygon to be considered is drawn using the same steps as previously discussed.

Title: Positive power-off circuit for electrical appliances
Inventor: VANCHA JOHN
IPC: H01H9/54
Filed: 1991-03-11
Granted: 1995-04-18
Abstract: A power-off control circuit for a household appliance, including a manually operating momentary switch having conductive and non-conductive states.  The switch is connected to a source of electric power so when the switch is momentarily manually operated into the conductive state, power flows into the power-off control circuit.  There is a power regulator connected to the manually operating switch for receiving the power during the conductive state and for converting the received power into a voltage.  A timer is connected to the power regulator and when activated, initiates a predetermined time period in which the household appliance operates.  The circuit also includes a relay connected to the timer and the source of electrical power so as to be in parallel with the manually operating switch.  The relay operates in a conductive and non-conductive state and is in the non-conductive state until receiving a signal from the timer at which time the relay changes to the conductive state. Now, the power regulator receives power through the relay until the relay changes to the non-conductive state and power is prevented from flowing through the power-off circuit.

Title: Method of carrying out an authentication check between a base station and a mobile station in a mobile radio system
Inventor: DENT PAUL WILKINSON
IPC: H04L9/32
Filed: 1991-01-29
Granted: 2001-04-03
Abstract: A method of carrying out an authentication check in a mobile telephone system in which an authentic base station (BS) serves a plurality of mobile stations (MSl-MSn). It is earlier known to carry out a unidirectional check from the base station (BS) to a calling mobile station (MSk). A false base station (BSf) is able, in this way, to carry out a false authentication check, by collecting a number of so-called RAND-Response pairs. In order to avoid this, there is introduced a further unidirectional authentication check, base station-mobile station, and also an authentication check from the mobile station to the base station. According to one embodiment of the method, the unidirectional check is excluded and only the bidirectional authentication check is carried out.

IPC: C07C273/04
Filed: 1992-03-20
Granted: 2005-11-08
Abstract: A urea production process in which the urea solution produced in the reaction zone is treated in sequence with a first thermal decomposer at the same pressure as the reaction, to decompose part of the residual ammonium carbamate into its components, then with an adiabatic stripper in which the free ammonia is stripped with CO2 operating at a pressure which is 1-7 MPa less than the synthesis pressure, then with two further carbamate thermal decomposition stages at decreasing pressures. The gaseous products obtained from those stages at pressures less than the synthesis pressure are mixed with the recycle solutions from the downstream stages, condensed by heat transfer against said downstream stages, and then recycled to the reaction as liquid.

Abstract: This invention relates to a spray type retort sterilizer which performs various kinds of high-pressure sterilization of gas foods containing a lot of gas, transfusion soft pack for medicine, etc. and it object is to prevent the hot water drops spray on the object material for treatment (3) placed on the trays (2) disposed inside the tank (1) from instantly evaporating by boiling.      The technical construction of this invention is that it is provided with a tank (1) in which trays loaded with the object material to be treated are stacked in a plural number of stages, spray units (4) which emit hot water or cooling water on the object material (3) on the tray (2) in each stage inside the tank (1) and a circulation route (5) through which to blow the water accumulated at the bottom of the tank (1) in the form of mist from the spray units (4) again under pressure through a pump (6) and a heat exchanger (7) and is also provided inside the tank (1) with an internal pressure adjusting system composed of a pressurized air intake system (11) which introduces pressurized air into the retort and an exhaust system (12) which evacuates gas from inside the tank (1). In a retort sterilizer having a construction as described above, the internal pressure of the tank (1) can be set at a pressure at which the desired hot water drops are not instantly atomized by boiling with mutual operations of the pressurized air intake system (11) and the exhaust system (12), thus providing a unique effect of making it easy to provide a retort sterilizer of high practical value which can blow desired hot water drops exactly and uniformly against the object material in the tank (1) and equalize the temperature in the entire area of spraying to ensure a treatment of high efficiency.
