Title: Molded bow limb and method
Inventor: JOHNSTON RICHARD
IPC: F41B5/00
Filed: 1986-10-16
Granted: 1991-08-06
Abstract: Abstract of the Disclosure:           A bow limb which is totally molded essentially filled with unbroken longitudinal strands of fiberglass oriented in the central configuration in parallel strands, but as approaching the exterior of the bow, the strands conform to the exterior configuration of the limb.  The bow limb is also characterized by a substantially constant cross-section even though width and thickness may vary longitudinally.  This maintains a constant ratio of resin to fiberglass which is important to insure uniform strength characteristics.  If the concentration of resin to fiberglass becomes too great, a brittle or weak point which invites breakage can occur.  If the fiberglass to resin ratio is too great, inadequate bonding can result in bending failure.          The method comprises the steps of wrapping impregnated fiberglass strands around a frame to create a fiberglass and resin blank or package.  The wet blank or package is then placed in the mold to be shaped and cured.  The package has a calculated predetermined number of fiberglass strands, and also a calculated predetermined volume and weight of plastic resin.  The mold, has two parts, a male and female.  The volume of the mold may be simultaneously thinned and widened in forming the mold in such a manner that the cross-section is constant at any given point.  The thickness of the limb can be varried in accordance with the depth of penetration of the male member of the mold into the female.  A tail of the excess fiberglass and resin extends from both ends of the mold, and after the formed unit or paddle is first cured and then removed from the mold; these are removed with a saw cut.  The paddle is removed from the mold as soon as cured to the handling point, and then finish cured in an oven.          When totally cured the paddle is severed into two limbs.

Title: Controlling engine coolant flow and valve assembly therefor
Inventor: BRADSHAW CYRIL E
IPC: F16K31/04
Filed: 1987-06-15
Granted: 1992-08-18
Abstract: ABSTRACT      A motorized water valve of the butterfly-type having the motor case and gear reduction housing formed integrally with the valving chamber.  The metal butterfly has elastomeric material formed thereover to provide improved sealing and prevent leakage when the valve is closed thereby enabling substantially shortened warm-up in thermostat application. The control system employs the valve at the engine block outlet to control coolant flow to the radiator in response to an electrical control signal based upon comparison of the sensed block temperature with a desired engine temperature.  The control system also employs the valve to control coolant flow to the heater core in response to an electrical control signal based upon a comparison of sensed in-car temperature and a desired in-car temperature selected by the driver.  Heater core discharge air may also be sensed and included in the comparison to provide a control signal to permit automatic in-car temperature regulation.  An additional control signal also be generated from the comparison to control heater blower speed control.  The control system, upon cold engine starts, opens the radiator coolant valve fully for a short time to allow full flow to clean the valve and remove deposits, then returns to the closed position to continue engine warm-up.  The control system may also employ an outside air temperature transducer to provide a signal used in the comparison to enable automatic regulation of desired engine coolant temperature.

Abstract: PHN 12.013                                   20.6.1987 ABSTRACT: Arrangement for combatting intersymbol interference and noise.       An arrangement for combating intersymbol interference and noise introduced into a data signal transmitted at a symbol rate 1/T by a transmission channel having a memory span LT corresponding to a number of L consecutive data symbols, comprises a receive filter (RF), a first decision circuit (ID) for forming preliminary symbol decisions in response to the transmitted data signal, a second decision circuit (FD) for forming final symbol decisions, means (FFS and FBS) for compensating pre- and post-cursive inter-symbol interference, and a combining circuit (AD) for for-ming the input signal for the second decision circuit (FD). By selecting in these compensating means the memory span MT of the feedforward section (FFS), and possibly also the memory span NT of the feedback section (FBS), to be smaller than the memory span LT of the transmission channel, a simplification of the implementation of the arrangement is achieved, whereas the attainable transmis-sion quality does not appreciably differ from the transmission quality attainable with MT=NT=LT, (Fig.2).

Abstract: Abstract AN APPARATUS FOR QUANTITATIVELY               EXTRUDING FOOD MATERIAL    An apparatus for quantitatively extruding food material is provided.   In this apparatus the material is introduced into the space formed between the periphery of a drum and the side wall of a housing.  The drum has an inner chamber between its inner wall and the periphery of a cam.  A pair of blades is inserted into slits formed on the drum form a compartment in the outside of the drum and a compartment in the inner chamber.    Since the dimensions of the space in the compartment outside of the drum decrease towards the exit Port, while the space of the inner chamber increases,  the pressure in the space becomes much higher than that of the inner chamber.  Thus the air in the material is drawn out of the outer compartment into the unner chamber via a path formed between the recess on the trailing surface of the blade and the wall of the slit.  As a result material of a uniform quantity and density, and that has no air entraiment,  is extruded from the exit port.

Abstract: Abstract of the Disclosure METHOD AND APPARATUS FOR HIGH ACCURACY     MEASUREMENT OF VLSI COMPONENTS Methods and apparatus for accurately measuring propagation delay through very high speed VLSI devices with a test instrument having errors comparable to the delays being measured.  The VLSI device has a plurality of parallel operational signal paths, each with a very short propagation delay,  The VLSI device is fabricated with control circuitry for selectively connecting the parallel operational signal paths in series in a test mode so as to define a test signal path comprising multiple operational signal paths.  The test signal path has a relatively long propagation delay which can be measured with acceptable accuracy by the test instrument.  The test signal path is defined so that it bypasses clocked circuit elements on the VLSI device.  Since the operational signal paths are on the same integrated circuit and have very well correlated operating characteristics, the propagation delay through the test signal path is a good representation of the integrated circuit dynamic operation.  When the integrated circuit is not in the test mode, the series connections are disabled and the parallel circuits operate in their normally intended manner.  A minimum of circuitry is added to the VLSI device in order to implement the test mode.
