Title: Reusable coin counter and holding device
Inventor: BICKLE WILLIAM W
IPC: G07D9/00
Filed: 1990-01-09
Granted: 1994-03-15
Abstract: REUSABLE COIN COUNTER AND HOLDING DEVICE      ABSTRACT OF THE DISCLOSURE        While measuring racks and the like are known to count or measure the number of coins required to wrap same into rolls, the actual wrapping requires considerable experience and dexterity and can be time consuming.  The present device consists of a relatively thin plastic or card semi-circular trough having closed ends and a length equal to the required number of coins in a roll of that particular denomination with the curvature of the trough and length thereof varying with each denomination of coin.      The entire trough and measured contents may then be wrapped in a conventional coin wrapper readily and easily as the closed ends of the trough retain the coins during the rolling process.

Abstract: Chemorheologically viscosity tailored matrix resin formulation for use in forming prepregs and filament wound composite articles and having a specified viscosity profile comprising a curable matrix resin and an effective amount of a reactive resin curing agent reactive at room temperature and a latent resin curing agent substantially non-reactive at room temperature but activated upon heating or radiation such that the matrix resin formulation is adapted upon formulation to have a viscosity sufficiently low to enable the matrix resin to impregnate a filament or fiber at room temperature without the necessity for the application of heat or solvent and which, upon standing at room temperature after impregnation into the fiber or filament to form a prepreg composition, rises in viscosity to a viscosity level sufficiently high to prevent substantially any bleed of the matrix resin from winding tension upon spooling of the prepreg yet of sufficiently low viscosity to allow the prepreg to tack and drape in order to nestle and set during winding of a filament wound composite article from said prepreg after room temperature storage of the spooled prepreg material, and which matrix resin in the prepreg experiences a reduction in viscosity upon heating the prepreg composition, to a viscosity minimum sufficiently low to allow the matrix resin in the heated prepreg to flow and substantially eliminate formation of voids in the winding of a composite article from said prepreg yet not so low as to permit bleeding of the matrix resin from the prepreg and with the continued application of heat to the filament wound composite article to permit the matrix resin in the filament wound composite article to cure to a hardened or gelled state.

Patent CA-2050617-C (CA)
Title: Ball valve having improved inherent rangeability
Inventor: REYNOLDS DAVID C
IPC: F16K5/10
Filed: 1991-09-04
Granted: 1995-06-27
Abstract: In accordance with the present  invention,  a ball  valve, provided with a  floating ball that  is  rotatable through substantially 90°,  includes a pair of seats adjacent the upstream and downstream sides of the valve at least one of which seats is a one-piece lubricant-impregnated metal seat that makes full face direct sealing contact with the ball at all times during movement of the ball between its fully open and fully closed positions.   The seat includes a concave central surface portion which defines a pattern of spaced holes extending through the seat in the direction of the axial  flow passage through the valve housing,  said holes providing the only paths for fluid flow through the seat, whereby the  seat effects  a significant reduction  in the pressure of fluid flowing through the ball valve due to the fluid to metal contact of fluid passing through the holes in the seat.  The full face direct sealing contact between the ball and central surface portion of the seat is operative to prevent leakage of fluid from the bore of the ball through any of the holes in the seat that are covered by a surface portion of the ball, and permits fluid to flow through only those holes in the seat that directly communicate with the bore of the ball as the ball is rotated from one position to another about its axis of rotation.   Since the ball in the present invention is a floating ball,  and makes full-face contact with a seat that is constructed of good bearing material, the valve need not employ a thin flexible metal seat to provide a seal between the ball and the housing as in the Baumann arrangement, and allows the ball to seal directly to the seat throughout the stroke of the ball.   The holes that are  shrouded are truly "off", not just flowing less. In addition, due to the floating nature of the ball, and its full-face contact with the multi-hole seat, the valve design is self-compensating for wear,  and continues to seal well even after wear has occurred.

Title: Method and arrangement of coherently demodulating psk signals using a feedback loop including a filter bank
Inventor: ICHIYOSHI OSAMU
IPC: H04L27/00
Filed: 1992-09-21
Granted: 1996-10-29
Abstract: In order to coherently demodulate an incoming multi-phase PSK analog signal irrespective of large frequency deviation, an automatic frequency feedback loop is provided.  An analog baseband signal is generated by multiplying the IF analog signal by a local signal and then is converted into the corresponding digital baseband signal.  A multiplier multiplies the digital baseband signal by another local signal.  The output of the multiplier is further multiplied and then applied to a plurality of single-tuned filters which are arranged in parallel and have tuning frequencies each different from an adjacent frequency by a predetermined frequency interval.  Each of the plurality of single-tuned filters generates a signal for use in carrier recovery, a frequency error signal and a correlation coefficient. Subsequently, one of the plurality of single-tuned filters is selected in a manner wherein the maximum value is detected among the correlation coefficients.  The another local signal is generated using the frequency error signal of the single-tuned filter which has been selected.  A modulating signal is reproduced using the recovered carrier in a conventional manner.

Title: Optical viewing and near infrared tracking system for a portable missile launcher
Inventor: CARLSON JAMES J
IPC: G02B27/10
Filed: 1992-11-17
Granted: 1997-03-04
Abstract: An optical system (10) for portable missile launcher (23) includes an objective lens (12) for receiving the entire visual and near infrared light energy emanating from a target (14) and immediate background of the target.  The light energy from the objective lens then passes through a Porro prism assembly (16) which acts to direct visual light along a first path to an eyepiece (20) and near infrared along a second path at approximately a right angle to the first path where it is received by a tracker assembly (22) and monitored.  The Porro prism (16) is constructed in accordance with this invention to include a multi-layer interference dichroic coating (18) disposed between the two prisms (34, 36) which make up the prism assembly.  This coating is of such a nature as to readily permit light energy in the visual range to pass directly through the coating, but at the same time to reflect the near infrared components along a second path bringing them to focus on the tracker assembly (22).

Granted: 1996-11-12
Abstract: An adaptive stepper (22) for adjusting welding heat boost to compensate for deterioration (flattening) of the electrode tips of a welder (15). Heat boost is provided to the welder (15) as a function of expulsion rather than by a series of linear step profiles specified by a weld engineer. An operator sets up an adaptive schedule based upon an expected resistance difference between consecutive half-cycles considered to be "normal". If differences equal to or less than the normal level are detected during a group of welds, the heat boost will be incremented by 1 % after a preprogrammed number of welds have been made. If differ-ences greater than normal are detected, indicating expulsion, the boost will be decremented immediately by 1 % between in-creases, if decrements are allowed at the time.
