Abstract: A seismic detector for boreholes is described that has an accelerometer sensor block for sensing vibrations in geologic formations of the earth. The density of the seismic detector is approximately matched to the density of the formations in which the detector is utilized. A simple compass is used to orient the seismic detector. A large surface area shoe having a radius approximately equal to the radius of the borehole in which the seismic detector is located may be pushed against the side of the borehole by actuating cylinders contained in the seismic detector. Hydraulic drive of the cylinders is provided external to the detector. By using the large surface area wall-locking shoe, force holding the seismic detector in place is distributed over a larger area of the borehole wall thereby eliminating concentrated stresses.

Abstract: A golf club head with improved sole portions. Specifically, golf club head (10) having a sole (20) comprised of a leading portion (28) and a trailing portion (30), both portions defining surfaces with positive bounce angles.

Abstract: A golf swing training device which is used by both amateur and professional golfers to develop and maintain a proper golf swing. The golf swing training device not only forces the user to maintain one swing plane, but also allows the golfer to imitate the hand movement used in a proper golf swing, as well as allowing for the full extension of the golfer's arms in the follow through. Additionally, the golf swing training device develops the proper muscle groups for golfing.

Abstract: A method for inventory maintenance and leak detection in liquid storage tanks and dispensing lines, that combines tank level measurements, tank product temperature measurements, output flow measurements, liquid product characteristics data, initial product delivery volume data, and redundantly calculates changes in the quantity of liquid product within the tank and compares these calculations to determine abnormalities in the changes in the quantities of product within the tank. Changes in the quantity of product within the tank are verified as either the delivery of additional product into the tank or the dispensing of product from the tank as with a customer sale. Changes that cannot be verified as either delivery into or dispensing from the tank are appropriately characterized as possible leak conditions in the tank or lines.

Abstract: A method and apparatus for stimulating the production zone of an oil well having a high pressure gas gun and a coil tubing conduit to deliver cleaning, stimulating, and cooling liquid to the zone while firing the gun. The coil tubing conduit has discharge ports positioned to allow discharge of the liquid at or near the gun to provide cooling of the gun's electrical transmission line and the gun's moving parts. The gun may be gradually withdrawn from the production zone while continuing to fire the gun to stimulate the production zone.

Abstract: A measuring sensor having a magneto-elastic element and an electronic resonant circuit for sensing mechanical stress of an object. The sensor is firmly attached to the object being measured and creates a resonance frequency. The resonance frequency is transmitted to an aerial in a contactless, position-independent manner.

Abstract: A combination of a freezer/refrigerator appliance door ajar alarm indicating system with an appliance occupant emergency condition indicating system in a single unit utilizes two visual indicator means, one for each of the emergency conditions, and an audio alarm means with two tone operation, one for each of the emergency conditions indicated. The alarm system incorporates a first light indicator means in conjunction with a first audio alarm means that is triggered in response to a door ajar condition switch is being activated for longer than a preset period of time. The time period before the alarm is triggered may be adjusted by means of timer circuitry. The alarm system also incorporates a manually operated switch installed on the interior of the appliance that allows an occupant of the appliance to indicate to those on the outside the existence of an emergency condition that requires assistance.

Abstract: A device for supporting a canopy. The device comprises (a) two joints each comprising (1) a clamp for connecting with a corresponding handle support of a baby stroller and comprising a first finger and a second finger comprising an upper recess and a lower recess and (b) a strip connecting with the second finger and comprising an upper recess and a lower recess and (b) two canopy shelves each comprising (1) a first member for supporting the canopy and (2) a second member connecting with the long member at an angle and comprising two sides respectively comprising two protrusions. The second member of the canopy shelf can be moved past the strip so that the protrusions engage in the recesses and so that the canopy shelf is retained in an upper position for shielding occupants. The clamp also has a protrusion projecting therefrom between the fingers and penetrating the handle support, for restraining the device from rotating about and sliding along the handle supports.

Abstract: An apparatus and method for determining the freezing point of substances, particularly liquids, that are likely to be used in environments that subject them to temperatures at or near their freezing points. The apparatus and method achieve a determination of the freezing point of the substance without the necessity of rigidly controlling the warming and cooling of the substance and without mistaking errant fluctuations in the thermal behavior of the substance for the freezing point. The apparatus includes a test sample cell that is cooled by direct contact with a rapidly expanding gas and a means for recording and analyzing temperature and time data for a test sample within the test sample cell. Means for controlling the test and displaying the information/data are also provided. The method utilizes a numerical analysis means to arrive at a freezing point value without the necessity of complex differentiating electronics or calculations.

Abstract: A sail tensioning device comprises a handle 70, an arm 73 and a tube 75 which fit together to form the device. The handle is fixed by a strip of webbing which fits in an opening 77 and is stitched to a sail to provide an anchor for the handle. The arm 73 fits in a cavity in the handle 70 to pivot about an intermediate point of the handle and urge the tube 76 against a batten (not shown), as the handle swivels about the anchor. Urging the batten in this way forces the batten against a remote end of a batten pocket to tension the sail.

Abstract: A method and device (10) is provided for safely removing a needle from the barrel of a syringe and for protectively storing the needle. A housing (16) contains V-shaped jaws (26) which are resiliently hinged, lined with a face of rubber or other gripping material, and biased towards a closed position. The round hub of the needle of a syringe is urged into the mouth (27) of the "V" until it is tight enough for the user to rotate the barrel without the hub and needle moving, thus disconnecting the needle from the syringe. A lever (44) engaging the housing (16) forces the jaws (26) to open, thus dropping the needle from the lid-mounted device into a container beneath.

Abstract: The invention relates to a method and a device for controlling the operating brake pressure to pressure medium brakes in a vehicle combination comprising a tractor vehicle and at least one trailer vehicle. The vehicles in this case are connected by a conventional coupling device that includes standard brakeline connections. Forces developing in the coupling device are measured during the course of braking and are reduced to a predetermined value by adjusting the brake pressure for at least the brakes of the trailer vehicle in dependence on the longitudinal inclination of the tractor vehicle and of the actual deceleration thereof. The adjusted value of the brake pressure is retained for the purpose of being the starting value at the next braking of the vehicles.

Abstract: A retrievable pessary for intravaginal or intrarectal use comprises a solid body comprising a pharmaceutically active ingredient; a net pouch which encloses the body; and a withdrawal cord attached to the pouch to enable the pessary to be withdrawn after use.
