Abstract: Abstract A method and apparatus for cooling at least the inside of steel pipes. Cooling is effected while restraining the radial displacement of a pipe at a point not more than 500 mm, or preferably not more than 250 mm, away from each end of the pipe and at intermediate points spaced at intervals of 1.0 m to 2.5 m. Elliptical deformation in the cross section of larger-diameter pipes also is pre-vented by adding to the aforementioned cooling method and apparatus a device and step to rotate the pipe being cooled at a rate of 30 to 150 tines per minute. The restraining device at one end of the pipe is designed to move in the direc-tion of the pipe axis so that the restraint of the radial displacement at a point not more than 500 mm away from that end is at all times ensured even when pipe length varies.

Abstract: ABSTRACT         A first signal at a first frequency which is a selected harmonic of the resonant frequency of a bolt in a first loaded condition is determined.  Then there is determined a second signal at a second fre-quency being the same harmonic of the resonant fre-quency of the bolt in a second loaded condition.          Both frequencies are multiplied by a factor M.  The up input of a counter receives one of the signals for a predetermined duration, and the down input re-ceives the other signal for the same duration.  The number of pulses remaining in the counter is repre-sentative of the difference in load between the first and second loaded conditions.

Abstract: MOISTURE ABSORBENT CONDIMENT CONTAINER Abstract of the Disclosure:         A container for condiments including a main container and a perforated inner container secured therein, for sugar, or salt, or spices, etc., referred to as condiments.  An absorbent material is placed in the inner container, which may be rice, for example.  The inner container is provided with perforations small enough to confine the absorbent material, but they admit air to freely flow therethrough.  The inner container is re-movable, for enabling placing the absorbent material therein, or changing it.  In one of the forms, also, the inner container is mounted for swinging motion to physically loosen the con-diment in the main container.  In a second embodiment a cap is on the main container having a space for absorbent material, and a perforated disc holding the absorbent material in the cap.  The main container also has a perforated disc enabling the condiment to be shaken therethrough.  When the closure cap is in closed position the entire interior space is closed to the exterior, and the moisture in the condiment is enabled to pass through the perforated discs and be absorbed by the absorbent material.  In one form of the second embodiment, the closure cap is held by screw threads and is entirely detachable, and in another, it is yieldably moved to open position, although still attached, and is automatically moved back to closed posi-tion when released.  In this case, interfitting elements center the cap on the body.  The absorbent material includes various kinds of rice, and a selection of chemical materials.

Abstract: WELL PRESSURE COMPENSATION FOR      BLOWOUT PREVENTERS                          Abstract A method and apparatus of compensating for the closing force on a blowout preventer caused by well pressure for reducing the wear on the blowout preventer sealing element when moving a drill string through a closed blowout preventer.  A hydraulic opening force is applied to the blowout preventer which is actuated by and is propor-tional to the well pressure.  A compensating line is connected between the blowout preventer fluid supply line and the blowout preventer opening line.  A control valve is provided in the compensating lines for applying an opening force on the blowout preventer and a pilot control pressure regulator is provided in the compensating line for limiting the compensating pressure.  The pilot control line is con-nected between the regulator and the well pressure in the blowout preventer whereby the output pressure is proportional to the well pressure for compensating for the closing force on the blowout pre-venter caused by the well pressure.

Abstract: A b s t r a c t Two low-speed two-stroke diesel engines (11, 12) are disposed consecutively in the longitudinal direction and parallel to the longitudinal axis (10) of the vessel in the hull (18) per propeller (16) and for direct propulsion of the propeller (16) are connected to the same via a common line of shafting (21).  A coupling (13) is disposed in the line (21) between the engines (11, 12). The direct drive eliminates any transmission losses between the engines and the propeller and the vessel running costs are low because of the low specific fuel consumption of low-speed two-stroke diesel engines.

Abstract: ABSTRACT OF THE DISCLOSURE         A four-wheel drive agricultural tractor with in-dependently steered ground engaging wheels supporting a flat, extensible load supportive frame includes an operator's cab that is adapted to face the direction of travel.  Mounted under the frame is an internal combustion engine, clutch, and trans-mission which are individually controllable from the cab. A system of shafts and gears couple motive power from the trans-mission to pairs of wheels and a system of hydraulic steering motors are controllable from the cab for effecting either coordinated or crab steering.  Fabricated of box-girders, the frame includes fixed and slidable portions that are mutually displaceable by hydraulic rams located within the frame to vary the wheelbase and tread of the tractor.  The frame also includes an articulated hinged member at each end carrying a hydraulic stabilizer.  Both stabilizers are hydraulically interconnected and function to maintain all wheels on the ground while traversing uneven terrain and various novel mounting and locking arrangements are disclosed for attaching and carrying implements on and under the frame.

Abstract: ABSTRACT OF THE DISCLOSURE:           An averaging method which eliminates periodic strays and which is used in analog-digital computers per-forming an averaging procedure. Such a procedure which processes a set of signals picked up from an examined object elicits an averaged evoked response due to its capability of reducing internal noise and periodic strays originated in an environment comprising a mains supply network proportionally to the square root of N-sweeps of the procedure, and in the case where the periodic strays and external stimuli are synchronous, the averaged periodic strays are not sufficiently reduced and distort the averaged evoked response making its right interpretation difficult. In order to overcome this problem, the averaging method eliminates the periodic strays from the set of signals during the averaging procedure in greater extend i.e. proportionally to the number of N-sweeps of the averaging procedure resulting in their at least N-fold reduction thanks to introducing a phase shift by an angle .alpha. of the 120° ? .alpha. ?240° interval related to the period of the strays which controls periods of the external stimuli and initial phases of the periodic strays at the beginning of two successive periods of the external stimuli, or alternately at the beginning of two sucessive sweeps of the averaging procedure differing by the value of the introduced phase shift, i.e. by .alpha..

Abstract: Abstract:      A kitchen utensil for facilitating the removal of the contents from boil-in-the-foil type food pouches (retort pouches).  Such retort pouches are usually made from a laminate of three materials, i.e. polyester, which forms the outer layer, aluminum foil, which forms a barrier in the middle, and an inner layer of polypropylene to retain the food taste.  The utensil has an elongated handle and a pair of elongated prongs extending in parallel from the handle at one end.  The length of the prongs is at least as great as the width of the pouch.  The prongs define a gap between them dimensioned to snugly receive two layers of the pouch material.  The pouch can thus be inserted into the gap and the prongs moved over the pouch to cause the contents to be squeezed towards one end of the pouch.          The utensil preferably also has a pouch opening device located at the free end of one of the prongs.
