Title: Sealing ring and method and apparatus for making same
Inventor: SCHOLIN HAROLD W
IPC: B23B1/00

Granted: 1985-12-10
Abstract: Abstract of the Disclosure A  sealing ring is disclosed which is formed of an elastomeric material wherein the cross section thereof has a plurality of substantially flat surfaces, and wherein the inner and outer diameter surfaces, which are the sealing surfaces thereof, are molded surfaces.  The remaining sur-faces are machined or cut surfaces.  The preferred number of surfaces or faces in cross section is 8, and this has been found to give the best results, although other numbers of surfaces may also be used.  Since the ring itself is not molded ring, but has only the inner and outer surfaces thereof which are molded, there is also disclosed a novel method of making such a ring, as well as a novel apparatus for use in carrying out the method of making the ring, wherein a molded elastomeric sleeve is provided and wherein inclined surfaces are cut therein in such a way that when the ring is severed from the sleeve it will have the desired number of flat surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the production of beneficiated coal and coal slurries having low ash, and sulfur involv-ing admixing coal in an aqueous medium with a surface treating admixture comprising a polymerizable monomer, polymerization catalyst and a liquid organic carrier thereby rendering said coal highly hydrophobic and oleo-philic.  The resultant beneficiated coal product is formed into coal slurries, such as coal-oil mixtures.  In another embodiment, an improved process for the beneficiating of coal and the separation of impurities therefrom is disclosed comprising subjecting coal to surface treatment by contact with an aqueous medium comprising polymerizable monomer, polymerization catalyst and liquid organic carrier, thereby rendering said coal hydrophobic and oleophilic, the improve-ment comprising the high shear intermixing of the surface treated coal with at least one water wash medium thereby providing for the removal of further hydrophilic impuri-ties, such as mineral ash, from the coal.  Apparatus for carrying out the process and the products prepared there-from are also provided.

Abstract: CONTROL ARRANGEMENT FOR A           VARIABLE PULLEY TRANSMISSION            Abstract:      A continuously variable transmission (CVT) with adjustable width pulleys has its belt tension and ratio controlled by an electronic-hydraulic system.  The CVT also has a fluid-cooled clutch on the output pulley shaft.  The engine speed, transmission output speed, throttle position, and gearshift position are sensed, and signals re-presenting this information are passed to a computer. The computer provides set point signals denoting desired engine speed, line pressure, and clutch cooling condition to a control system.  An electro-mechanical valve (408) assembly regulates fluid flow to the CVT primary sheave (30), to control CVT ratio as a function of the computer provided set engine speed signal.  A further electromechanical valve (414) assembly controls the line pressure in the hydraulic system, which is applied to the secondary pulley (36) to maintain belt tension, as a function of the set pressure signal provided by the computer.  A solenoid-operated valve (420), regulated by the control system (406), either returns waste fluid from the second valve assembly directly to sump, or passes the fluid to the clutch when cooling is indicated.

Abstract: ABSTRACT OF THE DISCLOSURE      Ignition pulses derived from an engine ignition coil primary are fed to the input of an ignition interruption circuit that employs an integrated circuit timer.  The state of the output  terminal of the timer is governed by an RC time constant circuit and by resetting signals supplied by a trigger circuit in response to occurrence of each ignition pulse. The timer output is coupled to the gate of an SCR which when it receives gate current as a result of the timer output being in a high state becomes conductive and bypasses ignition pulses to ground to thereby lower engine rpm to a preset minimum in which case gate current is removed and at least enough ignition pulses are allowed to be unbypassed for keeping the engine running above stalling speed.  The timer, in effect, compares the interval between pulses with its time constant.  When the intervals are longer than the time constant period the timer output remains low and provides no gate current, but when the opposite condi-tion exists gate current is supplied until the inter-vals between ignition pulses equal or exceed the time constant period.

Abstract: Abstract of the Disclosure A fluid displacement measuring cylinder has near its ends, respectively, an inlet and an outlet.  A fluid dis-placement measuring piston is adapted to travel through the measuring cylinder as a fluid barrier.  A control piston having first and second sides is adapted to travel through the control cylinder as a fluid barrier.  A rod connects the control piston only to the side of the measuring piston facing toward one end of the measuring cylinder.  A gas pressurized plenum chamber is connected to the control cylinder so the force of the gas pressure urges the measuring. piston toward the other end of the measuring cylinder. The movement of the measuring piston through the measuring cylinder is sensed and the movement of the control piston through the control cylinder is fluidically controlled. The pressure in the plenum chamber, which has a substan-tially larger volume than the control cylinder, is selected so as to cancel the force imbalance caused by the rod.

Abstract: DUAL-MODE DIELECTRIC LOADED CAVITY FILTER WITH           NONADJACENT MODE COUPLINGS             Abstract An electromagnetic cavity filter (10)  is formed by at least  two  cavities  (12)  having  electrically  conductive walls (40,  15).   When  more  than  two  cavities  (12)  are employed,  their  midpoints  do  not  have  to  be  colinear; rather,  it  is  sufficient  that  the  angle  formed  by  the midpoints of any three successively coupled cavities is an integral multiple of 90°.  Thus,  a folded "engine block" geometry  can be  realized  such  that  the  filter's  input cavity (12)  is proximate to the output cavity (12).  This allows a canonic filter response.  Each cavity (12) is the equivalent to two filter poles because two orthogonal modes of  electromagnetic  radiation  can  resonate  therewithin. Electrically nonadjacent modes of proximate cavities (12), as well  as  electrically adjacent modes,  can be coupled, permitting   elliptic   filter   functions.    Electrically nonadjacent modes  are  coupled by means  of an  iris  (30) opening  between  the  two  cavities  (12).   Electrically adjacent  modes  are  coupled  by means  of  an  electrically conductive probe (22) penetrating each of the two cavities (12).  A dielectric resonator (20) can be disposed within each cavity (12) to reduce the physical size of the cavity (12) while preserving its electrical characteristics.

Abstract: A b s t r a c t A method in signal processing of a train of pulses with a stable, high repetition frequency fr, in par-ticular in connection with dispersion measurements of optical fibers, comprises sampling (1) of the received signal at a sampling frequency fs, where   (n is an integer and .DELTA.f is several magnitudes smaller than fr).  When the sampling frequency is generated by a pulse generator (3), which, through a phase-detecting circuit (4), depends on partly a reference signal (from the oscillator 6) and partly a low frequency sig-nal derived (via 5) From the signal received and sampled at the frequency fs, a stable sampling fre-quency is obtained even though the signal/noise ratio on the input of the receiver  is significantly smaller than was permissible in the past. When the method is to be carried out within a relatively narrow repeti-tion frequency range, the oscillator (6) is preferably replaced by a frequency dividing circuit designed to generate a reference signal by division of the sampling frequency.

Abstract: ABSTRACT    A process for producing a propylene block copolymer by a three-step reaction in the presence of a stereoregular catalyst.  At the first step, propylene is polymerized at a temperature of 55°C or more to form polypropylene having an intrinsic viscosity of from 0.5 to 3.5 in the prescribed amount.  At the second step, propylene is polymerized at a temperature of from 30 to 90°C to form polypropylene having an intrinsic viscosity of at least 4 in the prescribed amount.          And at the third step, ethylene and propylene are copolymerized at a temperature of from 30 to 90°C to form an ethylene-propylene copolymer having an intrinsic viscosity of at least three in the prescribed amount.  The propylene block copolymer formed by the three steps is superior and well balanced in impact resistance and stiffness.
