Abstract: AUTOMATIC FUEL IGNITION APPARATUS    Abstract of the  Disclosure An apparatus for fluid fuel ignition which consists essentially of an igniter which reaches a temperature above the ignition temperature of the fuel when sufficient electricity from an electrical source passes through the igniter and which igniter remains continuously at a tempera-ture above the ignition temperature of the fuel while the fuel passes through a fuel injection means proximate to the igniter.  A thermal delay relay which activates a valve, which permits fuel to pass through the fuel injection means proximate the igniter, is responsive to current flow through the igniter after the igniter has reached ignition tempera-ture.  The apparatus requires no mechanical moving parts other than a thermostat, one electrical relay and a fuel valve responsive to an electrical signal. Only two sets of electrical contacts are required in the entire apparatus including the thermostat and internal relay contacts.       The apparatus may be conveniently designed to operate at either low or high voltage.  A low voltage thermostatic control may optionally be used in conjunction with a high voltage ignition which requires only one additional relay.

Abstract: ABSTRACT OF THE DISCLOSURE         A technique for generally determining the volume of a layer of a constituent material in a centrifugally separated mixture of material. A centrifuge tube is used to hold the material mixture and an appropriately shaped body is disposed in the tube in the zone occupied by the constituent material whose volume is to be measured. The body reduces the available volume within the tube which may be occupied by the constituent material, and thus expands the axial extent of the constituent material to make visual measurement of the constituent material more accurate.

Abstract: ABSTRACT OF THE INVENTION             ICE SKATE SHARPENER   The invention comprises an improved ice skate grinding, sharpening and contouring machine. The machine includes novel means to accurately center an ice skate between the heel and sole struts in a movable holding fixture and mean to select the best contour position on the blade as a function of intended skate usage. As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman. The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount. Means to adjust the blade position relative to the blade holding fixture for pitching are disclosed in one embodiment. In an alternative embodiment means for pitching the entire fixture as desired are disclosed. Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater.

Abstract: ABSTRACT OF THE DISCLOSURE             The potent hardenability effect of manganese and its relatively low cost and availability make it an attractive candidate for the production of high strength steels, especially in the range of about 2.0 to 6.0 percent manganese.  The main deterent to the use of such high manganese steels has been their poor toughness.  This can be improved by producing steels with high purity or with controlled low carbon contents.  However, the requirements of high purity and very low carbon tend to offset, to a large extent, the cost advantage of manganese.  The instant invention utilizes an intercritical anneal at a temperature just slightly above austenite start temperature (As) in order to form retained austenite at the grain boundaries. The steel is heated at temperatures from the (As) to about + 75°C for time periods varying from as little as one minute to 16 hours, the time being generally inversely proportional to the temperature.  While this annealing procedure will produce enhanced toughness for high purity steel containing controlled low carbon contents, it will also provide steel containing a combination of high strength (greater than 90 kai) with a CVN energy absorption value at minus 50°F of greater than 30 ft./lbs. even for steels containing normal impurity levels and conventional carbon contents.

Each of the valves includes a rota-table valve member in a combination retainer and seat.  The valves are connected to first and second pinion gears, re-spectively, and a rack engages each of the pinion gears.          The rack is attached to a piston which is disposed for reci-procation in a cylinder in response to fluid pressure on one side or the other of the piston.  Actuation of the piston in a first direction provides paths for component flow through the first and second rotatable valve members and through first and second orifices, respectively, into a mix-ing chamber.  The first and second orifices are disposed to provide impinging streams of the first and second components, the impingement insuring complete and thorough mixing of the components.  A nozzle is provided in the mixing chamber oppo-site the first and second orifices for dispensing the mixed components from the apparatus.  When fluid pressure is pro-vided on the other side of the piston, the first and second rotatable valve members are rotated to positions to block the flow of components into the mixing chamber.

Abstract: Abstract A multiprocessor system is described in which a plurality of central processor units share the same main memory over a common asynchronous bus.  Each central processor directs all memory requests to its own high speed cache memory.  If the request is to read data from memory, the cache memory control determines if the addressed data is present in the cache memory.  If so, the data is transferred to the processor without accessing main memory over the bus.  If the data is not present in the cache memory, the cache memory control gains access to the bus by a priority circuit and reads out the data from memory, storing the data in the cache memory at the same time that it transfers the data to the processor. If the memory request by the processor is to write data in memory, the cache memory control gains access to the bus and initiates a data store in  the main memory.  At the same time, the cache memory control determines if the existing data being overwritten at the addressed location in main memory is present in the cache memory.  If so, it updates the data in the cache memory at the same time it writes the data in main memory.
