Abstract: ELECTRIC RESISTANCE FURNACES FOR HIGH TEMPERATURE HEATING              Abstract of the Disclosure An electric resistance furnace adapted for operation at about 1,800°C or higher temperatures even in an oxidizing or neutral atmosphere is disclosed.   The furnace has a cylin-drical heating chamber defined by a generally cylindrical heat-ing element made of ceramic material, such as zirconium oxide and lanthanum chromide.   The heating element has a wall thick-ness which is very small at its middle section and gradually increases toward each end.   The middle section of the heating element defines the useful part of the heating chamber into which the heat generated by the heating element is effectively concentrated.   An electrode comprising an annular foil of plati-num is provided at each end of the heating element to pass elec-tric current therethrough.   A plurality of substantially equally spaced, longitudinally extending, parallel slots are present in the outer peripheral surface of each of the enlarged wall thick-ness portions of the heating element to provide allowance for thermal expansion of the heating element material.   There is also disclosed a method of applying the electrodes to the heat-ing element.

Abstract: ABSTRACT OF THE DISCLOSURE:           The method for producing the transmission device including coupling means connected to a sleeve comprises forming a collar from an apertured blank of the coupling means and cold forming projecting portions on the outer surface of the collar for connecting the collar to rotate with the sleeve.  The projecting portions may be formed by expanding the collar in a die from which die the collar is removed before connection to the sleeve.

Title: Pumped injection of gas for making foamed platic

IPC: B29C45/00
Filed: 1976-03-19
Granted: 1980-07-15
Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for making a foamed plastics product.  A foamed plastics product is formed by introducing into an at least substantially fully plasticated material a series of discontinuous gaseous bubbles while said plasticating material is under a substantial and often variable pressure, accumulating the material and intermixed bubbles in an injection zone while maintaining said pressure thereon and thereafter injecting said material into a mold whereupon said pressure is sufficiently released to permit expansion of said gas bubbles and the formation of a foam thereby.          Said gas is introduced, as aforesaid, by a series of separate injections wherein the pressure on the gas being injected rises from substantially zero to a level potentially in excess of the highest pressure expected to be developed within the plasticating means.  Thus, regardless of the pressure existing in the plasticated material at any given moment, gas will be injected into said plastic material when the pressure on the gas attains a suitable differential over the pressure in the plasticated material at any given moment and such injecting will be in substantially uniform quantities regardless of the pressure existing within said plastics material at the time of any given injection thereinto.       The apparatus aspects of the invention contemplate injecting the gaseous material into the plasticated plastics material by a high-speed positive displacement pump, as a piston pump or a diaphragm pump, wherein each stroke of the pump injects one bubble of gas into the plastics material.

Abstract: METHOD AND APPARATUS FOR HANDLING     SOLID FLUIDIZED PARTICLES            Abstract of the Disclosure A source of fluid and entrained particles including fines is connected to the entrance of a cyclone particle separator lying above a particle storage vessel that has an outlet near its bottom.  The particle separator has a particle exit con-nected to the storage vessel and a fluid exit.  The separator imparts angular motion to the fluid received at its entrance such that the fluid with a first percentage of the fines entrained therein flows out the fluid exit, and the particles minus such first percentage passes through the particle exit to the storage vessel.  The particles in the storage vessel are fluidized to a particular level above the outlet.  Fluidized particles with a second percentage of the fines entrained therein are removed from the process by withdrawal from the storage vessel at a point between the particular level and the outlet.  Fluidized particles minus the first and second per-centages of the fines flow from the outlet of the storage vessel to a receiver for processing.  The average size of the fluidized particles leaving the outlet is controlled by changing one of the percentages of the fines.  When the quantity of fines included in the fluid entrained particles from the source becomes too great, the angular operation of the separator is disrupted by injecting fluid into its base, or by raising the level of fluidized particles in the storage vessel to increase the percentage of the fines flowing out the fluid exit of the separator.  When the quantity of fines included in the fluid entrained particles from the source decreases, a portion of the fines withdrawn from the storage vessel is returned to the storage vessel to decrease the second percentage.

Abstract: Abstract of the Disclosure An automaton includes a work part supporting and manipulating system having sensors which provide signals indica-tive of the position of the work holder in a first coordinate system and a television system which can observe a part and generate signals representative of the position of the part in the television system's coordinate system.  A subsystem for generating conversion factors used to translate positions in the vision system coordinates into the manipulating system coordinates receives the output of both the manipulator sensors and the vision system while the manipulator moves a target through a series of points along a line.  The subsystem determines the angle of rotation between the two coordinate systems and the distance from the origin of one system to the origin of the other system through calculations involving lines drawn through the points in the vision system and manipulating system coordinates.  It also calculates a length scaling factor representing the ratio between an observed distance in the vision system and in the manipulating system.

Abstract: DEVICE FOR LAUNCHING AND DOUSING   LIGHT SAILS SUCH AS SPINNAKERS     ABSTRACT OF THE DISCLOSURE     The invention relates to a device for simplifying the launching and dousing of light sails.  It includes a set of smooth rings which encircle the sail at intervals up and down its height enabling the sail to remain furled while it is raised on the mast.  A hauling line connected to the lowermost ring pulls all of the rings upwardly to release the sail to the wind.  To douse the sail, a line running from the lowest ring and down the mast is hauled.          This line pulls the rings, which are connected to one another with a spacing line, back down around the sail, thus refurling it.

Abstract: RECEIVER FOR DATA TRANSMITTED BY MEANS OF THE INTERLEAVED BINARY PHASE   SHIFT KEYED MODULATION TECHNIQUE             Abstract A receiver in which the received signal is demodulated by means of an in-phase reference carrier and a quadrature reference carrier both of which are supplied by a clock and carrier recovery device, thereby supplying the in-phase and quadrature components of the sig-nal.  The sign of the sum of these components and that of the differ-ence between them are selectively gated to the output of the receiver under control of the clock signal supplied by the clock and carrier recovery device.  In this device, the frequency of the received sig-nal is doubled and the signal thus obtained is modulated by the clock signal at half the signaling rate extracted from the received signal. This modulation operation yields a signal at twice the carrier fre-quency from which the in-phase and quadrature reference carriers are extracted.
