Patent CA-2132393-A1 (CA)
Title: Optical detection of water droplets using light refraction
Inventor: ZIMMERMAN H ALLEN
IPC: G01N21/41
Filed: 1994-09-19
Abstract: ABSTRACT OF THE DISCLOSURE An optical detection system for detecting rain or other water droplets on the outer surface of a window and for detecting fog on the inner surface of such window with a single photo-detector is disclosed.  The optical detection method and apparatus of the invention measures the accumulation of water droplets on the window by light refraction of a first light beam with such droplets to redirect a first light beam to the photo-detector.  A masking device prevents such first light beam from reaching the photo-detector directly without refraction.  As a result the rain measurement output signal of the photo-detector increases with an increasing accumulation of water droplets on the window. The fog accumulation is measured by a second light beam reflected off the inner surface of the window to the photo-detector so that the fog measurement output signal of the photo-detector decreases with increasing amounts of fog since such fog scatters and diffuses the light to reduce the amount of light reflected to the photo-detector.  A third light source is focused directly on the photo-detector to bias it into an operating point of high sensitivity to infrared light and is connected in a negative feedback circuit from the output of the photo-detector amplifier.  The photo-detector output is connected to a narrowband amplifier that is tuned to the frequency of an oscillator which pulses the first and second light sources at different times.  As a result of this negative feedback, changes in the output signal of the photo-detector due to external factors such as temperature changes or aging of the light sources and photo-detector, as well as changes in the supply voltage and ambient light are cancelled so they do not produce errors in the measurement signals.

Abstract: The invention provides a wheat flour whereby speck formation in a secondarily processed product can be prevented and the deterioration in the color tone due to discoloration can be prevented. To treat tyrosinase of wheat bran which remains in wheat flour in the flour producing process and cause speck formation, a tyrosinase inhibitor is added prior to a roller milling step, preferably in a conditioning step.      Examples of the tyrosinase inhibitor include kojic acid, cysteine, glutathione, ascorbic acid, dithiothreitol, phytic acid, EDTA, isonicotinic acid hydrazide, p-aminosalicylic acid, ferulic acid, thiamine, peptides and combinations thereof. In particular, kojic acid and cysteine are preferable as a tyrosinase inhibitor. The wheat flour thus obtained is usable, for example, in fresh noodles, dried noodles and tenobe somen in a secondarily processed product.

Title: Bicycle lighting system and generator
Inventor: SCHWALLER EDWIN
IPC: B62J6/00
Filed: 1995-01-11
Abstract: A new type of bicycle lighting system has a high-capacity dynamo system (1, 5), including a dynamo generator (1), and a converter (5) connected thereto and to the lighting bodies to convert the electric power generated by the dynamo generator (1) into light and at the same time into a regulated direct voltage for loading a battery. The dynamo generator (1) consists of an inner and an outer circle (21, 22) that rotate both around a fixed, air-core coil (23). The pole pieces form together with the fixed air-core coil a highcapacity generator that reaches at least 90 % efficiency. This capacity ensures that the dynamo system (1, 5) generates enough electric energy to load the battery and at the same time to feed front and rear lights (2, 3) from a minimum driving speed of about 5 km/h. As long as the minimum driving speed is not exceeded, the converter (5) and the front and rear lights (2, 3) are additionally fed by the battery (parking light). Electronic components, such as a threshold value device (12-16) and a delay circuit (17) ensure that the disclosed bicycle lighting system generates a constant lighting voltage of about 6 V and that the ratio of distribution between the energy required for generating light and the energy required for loading the accumulator battery (4) lies between 1 and 2:1, regardless of the speed from about 5 km/h. When the battery (4) fails, the dynamo generator (1) feeds the light sources directly through the dynamo system.

Patent CA-2158493-A1 (CA)
Inventor: DIVETO ALBERT
IPC: A63B47/02
Filed: 1995-09-18
Abstract: The Golf Ball Retriever is designed for the purpose of retrieving golf balls from golf course water traps and other inaccessible areas on or off golf courses. The Golf Ball Retriever is a hand operated system which consists of a series of interacting telescopic tubes, a retriever cup, and a flexible activation line. A flexible line extends through the telescopic tubings towards the retriever cup where it is affixed to the outer edge of the cup at one end and the opposite end of the line is available to the operator for activation purposes. As the cup is placed over the golf ball, the flexible line which is hanging loose at the retriever cup is then pulled manually by the operator. As a result, the flexible line becomes rigid and taunt throughout the tubular sections and over the trapped ball in the cup thereby entrapping the ball into the cup. As the operator continues to pull on the line, the flexible line continues to secure the ball into the cup and this creates a tube retraction effect as the tubes are compressed into each other. The operator can then, maneuver the "compacted" tubing components and retriever cup into a desired area where the he can release the line to disengage the ball from the cup.

Title: Electromagnetic profile scanner
Inventor: HERMARY ALEXANDER THOMAS
IPC: G01B11/245
Filed: 1995-11-28
Abstract: A system for determining the shape and dimensions of a surface of an object includes a projector for projecting onto the object a spatially coded pattern of radiation, e.g., light. The system also includes a receiving device capable of imaging the reflected pattern, and a discriminator for determining which portion of the reflected pattern corresponds to which portion of the projected pattern. By this means, a received signal representing less than the complete reflection from the projected pattern can be correlated with a discrete portion of the scanned object.  The procedure is repeated to obtain enough reliable data to generate a reasonably reliable surface profile.  The resulting set of received signals and correlations are used to calculate the shape and dimensions of the object.

Title: Bait station with elevated rodenticide support
Inventor: JOHNSON DANIEL C
IPC: A01M25/00
Filed: 1996-05-01
Abstract: A bait station has a base with upwardly extending sidewalls and a hinged lid. A passageway for rodents such as rats is formed within the interior volume of the covered base by two converging barriers, the ends of which are spaced from one another to allow access to a rodent feeding trough. Each barrier is formed by a segment which extends upwardly from the base floor and a segment which extends downwardly from the lid. Upwardly opening slots are formed on the base barrier segments. A bait support rod extends between the two base barrier segments and is engaged in the slots. Bait units are supported on the rod generally above the rodent feeding trough. The support rod has a downwardly extending loop which engages between one base barrier segment and a wall of the feeding trough to restrict side-to-side movement of the rod.
