Title: Ion implantation surface charge control method and apparatus
Inventor: FARLEY MARVIN
IPC: H01J37/02
Filed: 1988-12-09
Granted: 1991-02-12
Abstract: Ion Implantation Surface Charge Control Method and Apparatus Abstract An ion beam neutralizer.  High energy electrons are directed through an ion beam neutralizing zone or region containing an ionizable gas.  As the high energy electrons collide with the gas molecules, they ionize the gas molecules and produce low energy electrons which are trapped by a positively charged ion beam.  As high energy electrons pass out of the neutralizing zone they are deflected back to the neutralizing zone by a cylindrical conductor biased to deflect the high energy electrons and an accelerating grid for accelerating the electrons back through the beam neutralizing zone.

Patent CA-1331840-C (CA)
Inventor: YANAGISAWA KOICHI
IPC: E21B49/00
Filed: 1989-06-05
Granted: 1994-09-06
Abstract: ABSTRACT OF THE DISCLOSURE    A low-water-pressure-controlled hydrologic test using a measurement pipe containing an inner packer which is equipped with a water pressure gage at its tip is disclosed.  Some water is poured into the measurement pipe in advance so as to diminish the pressure head difference between the in-pipe pressure and the pore water pressure of the rock concerned.          The permeability coefficient is obtained by measuring changes in the recovered water level in terms of pressure changes.  In the case of an aquiclude, the inner pressure is raised by expanding the inner packer, the permeability coefficient being obtained by detecting the changes in inner pressure.  Thus, the method allows a permeability test to be conducted continuously at various depths.  In addition, it helps to shorten the measurement time to a remarkable extent and enables the rock condition to be investigated without departing from the natural condition.

Inventor: SRAMEK JOHN A
IPC: A61K8/41
Filed: 1989-06-06
Granted: 1994-03-29
Abstract: ABSTRACT          Carboxyl radical containing resin hair setting or hair spray compositions possess improved adhesion to the hair and are more readily removed from the hair due to the use of certain long chain amine functional neutralizing agents containing a hydrophilic radical in addition to the amine radical as well as a long chain hydrocarbon radical such as lauryamidopropyl dimethylamine, polyoxyethylene (10) octadecylamine or a mixture of ether amines of the formula R6O(CH2)3NH2 where R is a hydrocarbon radical predominantly composed of C12 to C15 hydrocarbon radicals.  Up to 40%, and preferably from 5% to 30%, of the moles of carboxyl radicals to be neutralized are neutralized with such a long chain amine and the remainder of the carboxyl radicals to be neutralized are neutralized with an amine or an alkanolamine such as aminomethyl propanol.  More preferably, the compositions are hairspray compositions containing from about 10 to 80% by weight of a hydrocarbon-based aerosol propellant such as n-butane or isobutane.  The long chain amine serves to improve the hydrocarbon stability of such hairspray resins.

Title: Method and apparatus for testing photoelectric circuits
Inventor: JUDS SCOTT M
IPC: G01M11/00
Filed: 1989-07-05
Granted: 1992-11-24
Abstract: METHOD AND APPARATUS FOR TESTING PHOTOELECTRIC CIRCUIT   Abstract of the Disclosure The operability of a photoelectric sensor is tested by creating both an ON TEST and an OFF TEST. During the ON TEST a test light source, such as a light-emitting diode (LED), located in the vicinity of the light-detecting elements of the photoelectric sensor, is enabled to be energized. Alternatively, the light-detecting elements of the photoelectric sensor are by-passed and the output of the light-detecting elements directly energized. The ON TEST LED (or the by-pass) isinterconnected with the circuit that controls the energization of the normal or operational light source(s) of the photoelectric sensor such that the ON TEST LED will only ignite (or the by-pass will only operate) if current flows through theoperational light source(s). If the operational light source(s) are damaged and,thus, current cannot flow, the ON TEST LED will not light (or the by-pass will not produce an energizing voltage). A fault is indicated if the sensor output does not indicate the detection of light when the ON TEST is being conducted. In essence,the ON TEST creates (or simulates) light detection regardless of whether an object is located between the operational light source(s) and the light-detecting element(s) of the photoelectric sensor. During the OFF TEST, current flow through the operational light source(s) is inhibited. As a result, the light-detecting elements of the photoelectric sensor do not receive light. A fault indication is provided if the sensor output indicates the detection of light when the OFF TEST is being conducted.

Abstract: Applicant:  John B. Hey For:  System and Method of Predicting Subjective Reactions ABSTRACT OF THE DISCLOSURE    A system and method of predicting, for a user selected from a group of users, the reactions of the selected user to items sampled by one or more users in the group but not sampled by the selected user.  The predictions are based on other items previously sampled by that user.  A scalar rating is defined for each item sampled by the selected user to represent the reaction of the selected user to that item.  The selected user is successively paired with other users in the group who have defined scalar ratings for at least some of the items sampled by the selected user to determine the overall difference in ratings for items sampled by both members of each successive pair.  One or more of the other users are designated as predicting users and a weighting value is assigned to each of the predicting users based on the overall difference in ratings between that predicting user and the selected user.  The weighting values are applied for each item unsampled by the selected user to proportionally alter the difference between a rating previously predicted for each identified item and any actual ratings of that item by the predicting users to adjust the reaction predictions for the selected user.

Abstract: The reinforcing rod holder includes a hollow body (1) having a depression in which the downwardly bent reinforcing rods (2) are inserted in such a manner that their U-shaped anchoring portions protrude. The free end (3 and 4) of the reinforcing rods are disposed entirely in the hollow body, together with the bend portion. To permit insertion of the anchoring portions, the hollow body is provided with apertures (5), and holes (6) having a diameter which is approximately identical to the diameter of the reinforcing rods are provided at the two ends of such apertures (5), while the central portion of the apertures is sealed by two overlapping flaps (7). The hollow body is further provided with mounting or support ribs (8) at the apertures (5) and two spacer ribs (9 and 10) between the last three apertures (5) in order to serve as support faces for the ends of the reinforcing rods. The hollow body, containing the reinforcing rods, is filled with expanded plastic material. A reinforcing rod holder of this type is used in connection-type concreting operations and is advantageous in that, on the one hand, the portions of the reinforcing rods not embedded in concrete are packed in expanded plastics material and therefore cannot rust and, on the other hand, the expanded plastics material can be completely and conveniently removed by extracting the hollow body when the connection-type concreting operation is being carried out. In addition, the hollow body actually serves as a mould, thereby ensuring that the reinforcing rod holder is produced rationally and cheaply.
