Abstract: ABSTRACT OF THE DISCLOSURE        A lightweight sports neck and collarbone protector is provided for sports players, especially for lacrosse or hockey players, comprising a combined bib and upstanding collar to protect the clavicles and throat of the wearer respectively, the bib and collar being connected together along the entire length of their junction so that the collar holds the bib in position and an object such as a hockey stick or skate blade cannot pass between them.  Each of the bib and collar includes protective padding and armour members to overlie the clavicles and vulnerable front and side parts of the throat.  The padding may be foam padding and the armour members may be stiff plastics sheet material, the padding preferably being moulded from a soft plastics material as an integral member, while the armour members are moulded from a more rigid plastics material, also as an integral unit with a thin flexible connection between the armour members.  The padding and armour members may be adhered, stitched or otherwise fixed together against dislocation from an optimum position.

Abstract: METHOD FOR FIXING AN ANNULAR ELEMENT  ONTO A SHAFT AND A SHAFT ASSEMBLY      OBTAINED BY SUCH METHOD     ABSTRACT OF THE DISCLOSURE     The present invention relates to a method for fixing an annular element onto a shaft.     The shaft may be a camshaft and the annular element may be a cam piece or a journal piece used in an automobile.     The annular element is fixed onto the shaft by: engaging an axially extending projection of the element with an axially extending groove of the shaft so as to prevent a relative rotating motion; deforming an outer wall of the shaft adjacent to said groove at two positions near the terminating ends of the projection so that the outer wall protrudes into the groove, thereby fixing the element onto the shaft.

Abstract: Title of the Invention SUSTAINED IGNITION SECONDARY COMBUSTION UNIT Abstract of the Disclosure A sustained ignition secondary combustion apparatus in a housing of refractory insulating material includes a first level for conducting secondary air through a secondary air inlet and channel, and a second level for conducting smoke products.  A partition separates the levels or zones. Openings are provided in the partition between the levels bounded by a high temperature porous or fiberlike material in the form of igniter tube elements.   Secondary air and smoke products diffuse into the interstices of the porous or fiberlike material where contact and combustion maintains the igniter tubes at or above the ignition temperature. Ignition and secondary combustion of smoke products in the second level is therefore sustained and secondary air is preheated as it passes through the openings.  A secondary combustion zone is defined in the region of the openings between the levels and continues down stream through the exhaust outlet.  The first and second levels of the secondary combustion unit may be arranged in a variety of configurations for preheating of secondary air and primary smoke by counterflow with high temperature end products of secondary combustion.  Multiple or tortuous pathways may be provided for extended preheating.  Primary smoke may also be preheated by smoke preheating tubes.  The invention is also applied in a downdraft furnace.

Abstract: INFLATION VALVE Abstract of the Disclosure An inflation valve includes a valve body formed of a suitable rigid material and having a longitudinal passage therethrough. Internally the valve body includes an in-wardly extending annular member for supporting the valve element and providing a valve seat. This annular member has a predetermined longitudinal dimension between a trans-verse wall at one end and the base of the valve seat at the other end. The valve includes a valve element made of such size as to move freely within the aforementioned longitudi-nal passage. It includes a nose portion for engaging the valve seat at one side of the aforementioned annular member on the valve body and an enlarged portion for engaging the transverse wall. The valve element is dimensioned so that the distance between the nose portion of the valve element and the enlarged portion thereof is slightly less than the aforementioned longitudinal dimension of the valve body between the transverse wall and the base of the valve seat. The valve element is made of a flexible elastic material so that it may be compressed upon assembly. During assembly, the nose portion of the valve is forced through the passage of the annular member until this nose portion passes just beyond the valve seat; during this time the enlarged por-tion is compressed against the transverse wall because of the slightly lesser dimension of the valve element. Upon release of the assembly pressure, the resilience of the flexible valve element causes the nose portion thereof to be urged firmly against the valve seat in reliable sealing engagement.

Abstract: ABSTRACT OF THE DISCLOSURE     METHOD FOR THE INTERPRETATION OF MULTIPLE-POINT SURVEYING TECHNIQUES     In accordance with the present invention, progressive changes in amplitude as a function of offset of common gathers can be more easily identified by emphasizing the degree of amplitude variation between "near" and "far" amplitude vs. time traces of each gather along a seismic line, and displaying the resulting near and far offset sections side-by-side.          A significant -- and progressive -- change in P-wave reflection coefficient as a function of the angle of incidence (within sections) indicates valuable characteristics, say the fluid hydrocarbon-bearing potential and/or the lithology of the reflecting horizon.

Granted: 1987-11-03
Abstract: ABSTRACT OF THE DISCLOSURE     An enciphering key distribution system for use with a subscription television broadcast or cable television system is described.  In the transmitter an address generator generates addresses of subscribers to which a first enciphering key for enciphering a TV signal is to be distributed and an enciphering key generator generates second enciphering keys in response to the addresses.  The second keys are assigned a one-to-one correspondence with the subscribers.  A multiplier produces the product of the second keys associated with all the subscribers and an adder adds the first key to that product.  In the rec-eiver of a subscriber, the received signal is divided by the particular second key assigned to the subscriber which reveals the first enciphering key which is then used to decipher the TV signal.  The system simplifies receiver structure as data selectors for finding out the subscriber address are not nec-essary.

Abstract: Abstract The invention is a limiter circuit with dynamic hysteresis for providing improved distortion immunity at the circuit output in response to an input signal.  The limiter circuit includes a positive and negative peak detector.  Two weighted averages are taken of the positive and negative peaks, preferrably by means of a voltage divider network.  The first input to a comparator circuit receives the input signal to the limiter circuit. Different voltages from the voltage divider network are applied to the second input of the comparator circuit so as to create a dynamic hysteresis effect in the comparator circuit.  The different voltages are chosen in response to the output voltage from the comparator circuit by means of an analog switch.  The comparator circuit includes a fixed hysteresis voltage for stabilizing the limiter circuit at low level voltage input signals.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method for oil-wax separation is disclosed which comprises the use of a filtration zone (10)  followed by a centrifugation zone  (20).   The filtration zone produces a wax cake product which may be reslurried prior to being centrifuged, and a relatively wax-free filtrate product.   The centrifugation zone (20)  produces a relatively wax-free liquid which is recycled to the filtration zone (10) and a dry wax cake product having a relatively low solvent and oil content. A preferred centrifugation zone (20) comprises a scroll decanter centrifuge.   The disclosed process produces a relatively dry wax cake product.  This improves the dewaxed oil yield by having a reduced amount of oil entrained  in the wax cake product.   The process also reduces the energy consumption associated with wax recovery by decreasing the amount of solvent entrained in the wax cake.
