Abstract: METHOD AND APPARATUS FOR MEASURING UNDERGROUND FLUID FLOW CHARACTERISTICS D#74,956-F                    ABSTRACT OF THE DISCLOSURE     An underground logging tool is equipped with a gamma ray detector encircled by a rotatable shield featuring a colli-mator slot.  After the fluid in a formation is activated by a neutron source, the detector is used to obtain radiation count information as a function of horizontal direction as the shield is rotated.  Comparison of count rate data as a fun-ction of the shield slot orientation gives information con-cerning the direction of the formation fluid flow.  Measurements at different time intervals following the activation of the fluid, made with the shield retracted from the detector, may also be interpreted in terms of speed of horizontal fluid flow past the tool.

Abstract: ABSTRACT OF THE DISCLOSURE    A sensor device having a vibratable surface which can be exposed to various materials and used to determine the presence thereof is disclosed.  The device includes a sandwich structure comprising a substrate coated with a piezoelectric material, a pickup electrode joined to the piezoelectric and a drive electrode also joined to the piezoelectric.  The piezoelectric material is applied to the substrate as a slurry and when dried forms a ceramic coating which is chemically bonded to the substrate.  The sensor is electrically driven to vibrate and depending upon the absence or presence of the material to be detected a characteristic vibrational frequency or amplitude of the sensing surface is observed to indicate contact with such material. Various embodiments are discussed including a rectangular configuration which is cantilevered from a support base and a circular configuration which is held circumferentially by the support base.

Abstract: MICROWAVE OVEN           INVENTORS: HAROLD B. KAUFMAN, JR.          JOHN P. Mc CARTHY                       ABSTRACT         A microwave oven is disclosed which is especially useful for rapidly reconstituting frozen food products.  The oven includes a microwave cavity having a bottom hatch which is movable between an open position at which food to be heated or cooked can be loaded onto the hatch from outside the oven, and a closed position whereat the food is disposed within the cavity for heating or cooking by electromagnetic energy.  The hatch can be manually closed and, after a preset cooking time, automatically opened by gravity.  Also disclosed is a heat shield assembly mounted for movement relative to the bottom of the cavity, so that when the hatch is in its open position and electric (IR) heat is provided to supplement microwave heating in the cavity, the assembly covers the bottom of the cavity to prevent heat from radiating below the cavity when the food is supported on or removed from the movable hatch.  Accordingly, each batch of the food undergoes a uniform energy exposure, regardless of the time it may be left unattended below the cavity after the hatch is returned to its open position.  The oven can be cycled rapidly to provide an adequate supply of food products when used in a retail establishment.

Abstract: Abstract of the Disclosure:         An engine control system includes a microprocessor responsive to engine operating parameters for developing control words representing a desired dwell and firing time for use in controlling engine spark timing.  An engine control unit is coupled to the microprocessor and utilizes the control words in calculating the desired rise and fall of the spark timing output relative to reference pulses, indicative to engine crankshaft position.  The engine control unit includes a free-running counter which serves as a time reference for determining the period of the input reference pulses and for predicting the time of rise and fall of the output.  Prediction of the next rise is made when the output falls and prediction of next fall is made when the output rises.  Predictions are made on the assumption of constant frequency reference pulses.  Errors result-ing from this assumption are corrected when a reference pulse occurs.

Abstract: IMPROVEMENTS IN AND RELATING TO TAGS, PARTICULARLY EAR TAGS         ABSTRACT OF THE DISCLOSURE            A tag, particularly an ear tag for marking animals such as cattle which have passed an official test, comprises a strip formed into two limbs and a hollow rivet, preferably of brass, perpendicular to one of the limbs, the rivet comprising a stock portion which may be frusto-conical or cylindrical surmounted by a narrower neck portion of reduced wall thickness surmounted by an enlarged head portion preferably in the form of a cylindrical punch having a sharp cutting edge.  There is a receiver hole in the other limb of the strip to receive the rivet head and a spring clip, preferably of stainless steel, secured over the receiver hole.  As the tag is being closed, the head punches a hole in the animal's flesh, and is forced through the spring clip, after which the head may be splayed outwardly.  If an attempt is made to force the limbs apart, the spring clip interacts with the rivet to cause it to break at the neck portion.  Preferably there is a shoulder at the top of the stock portion against which the limb defining the receiver hole rests.  The rivet may be formed from the material of the strip.  A special insert for a tagging tool is also described, this insert having a conical boss set in the centre of a recess into which the head of the rivet is forced.  The tag is easy to apply by manual pressure, liable to break if an attempt is made to force it open and easy to check visually for evidence of tampering.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus is disclosed for obtaining second order velocity error correction signals for use in a time base corrector that removes instabilities in a video information signal reproduced from a magnetic medium.  The apparatus utilizes the phase of the color burst component of the video information signal from successive horizontal lines to determine the change in velocity error.  The change in the phase of the burst components of successive horizontal lines is first used to generate a first order or straight line approximation of the velocity error, and the difference between successive changes in burst phase, from which two successive first order error approximations are generated, is used to determine the approximate rate of change of velocity error.  This difference is used to generate an error compen-sating signal that is employed to phase modulate a clock signal that controls the reading of the video information signal stored in a memory in a manner whereby the time base instabilities due to velocity errors are substantially reduced if not eliminated.

Abstract: FLUID TEMPERATURE CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE     Fluid temperature control system for providing a sup-ply fluid at a select temperature by warming or cooling a first fluid with a controlled flow of a second fluid.  The control of the second fluid flow is achieved by a modula-tion valve adjustable in response to the pressure of a supply of servo fluid which is itself adjusted in response to the temperature of the supply fluid.  The adjustment of the servo fluid pressue by the control system is such that the change in servo fluid pressure from a steady state condition is initially great, diminishing with time to a lesser, steady state value, thereby enhancing the transient response of the control system.

Abstract: Height Adjusting System for Motorcycle Abstract:      A height adjusting system for a motorcycle body comprises front and rear telescopic suspensions connected to the axles of the two wheels and a high pressure air tank connected to the two suspensions and pressurised by an air pump driven by a motor.  A movable contact, driven by the speedometer of the motorcycle, engages a fixed contact when the motorcycle is either stopped or running at a low speed and completes a circuit to leak valves to exhaust the suspensions.  Electro-magnetic valves also exhaust the tank through check valves.  When the motorcycle runs at a higher speed the movable contact engages a second fixed contact to energise the motor to drive the pump to pressurise the tank.  The leak valves are closed and the increase of pressure raises the motorcycle body until a predetermined level is reached when pressure responsive change-over switches are operated to close the valves and stop the motor.
