Title: System to reduce wave shift error in spectrophotometer caused by hot spots in the light source
Inventor: HONIGS DAVID E
IPC: G01J3/02
Filed: 1990-12-06
Abstract: ABSTRACT OF THE DISCLOSURE An  improved  near  infrared  spectrophotometer  is disclosed which reduces wave shift errors arising from hot spots in a light source.  A ground quartz plate uniformly diffuses radiation from the light source to evenly illuminate the entrance slit for a diffraction grating.   Radiation emerges from the entrance slit with a uniform angular intensity distribution and is dispersed into a spectrum by a reflecting diffraction grating towards an exit slit.   A narrow wavelength band of  radiation passes  through  the  exit slit  to illuminate a sample.   Because the entrance slit is uniformly illuminated, without regard to variations in radiation intensity due to hot spots in the source, wave shift errors in the reflectivity measurements for the sample are reduced.

Title: Method and apparatus for accurately measuring the distance to a surface
Inventor: YOUNG JAMES E
IPC: G01K11/24
Filed: 1991-01-28
Abstract: METHOD AND APPARATUS FOR ACCURATELY MEASURING THE DISTANCE TO A SURFACE            Abstract of the Disclosure This invention relates to measuring the distance to a surface of an object using ultrasonic energy pulses.  An ultrasonic energy pulse is directed toward the object and the time is measured for the reflection to return so as to determine the distance to the object.  A reference ultrasonic pulse is directed through a fixed and known distance to provide a reference measurement.  To enhance the accuracy of the measurement, the air in the region traversed by the ultrasonic pulses is mixed by directing a swirling flow of air in this region so that the temperature of the air in the path of the reference measurement is more nearly representative of the temperature of the air where the distance measurement is taken.
Patent CA-2035419-A1 (CA)
Title: Electrical appliances
Inventor: O'NEILL ROBERT A
IPC: H01R13/58
Filed: 1991-01-31
Abstract: A cordless electrical appliance, for example an electric hot water jug, has a standard multi-pin type electrical connector on its appliance part and a cooperating connector on the base part. The pins of the appliance connector are oriented conventionally, namely generally horizontally as for a corded appliance, and are adapted to cooperate with shuttered spring terminals in the base connector, the arrangement being such that as the appliance part is lowered generally vertically onto the base part the horizontal pins on the appliance connector enter respective apertures in the base connector and displace the shutter thereby enabling the terminal ends of the spring terminals to move forwards into electrical contact with the ends of the pins on the appliance part. The use of a standard connector arrangement on the appliance part means that the appliance can be used in a corded or cordless manner and has cost advantages. A control on the appliance, eg. an element overtemperature protector on a hot water jug, can be arranged to prevent the base connector from coupling electrically to the base connector, and the base connector can advantageously comprise a unitary structure provided with its own cable clamp.
