Abstract: STATOR SLOT WEDGE ASSEMBLY ABSTRACT OF THE DISCLOSURE     A stator wedge assembly provides a spring force to assist in retaining a conductor securely in a slot without requiring a separate spring.  Two ends of the assembly are received in a dove-tail at the mouth of a slot.  A central spring section extends between the two ends and is slightly narrower than the walls at the mouth of the slot so that it is free to flex.  The central part of the central spring section has an increased thickness extending towards the conductor in the slot.  At least one wedge is inserted to press against the conductor in the slot on one side and to press against at least one of the two ends and the central part of the central spring section on the other side forcing the central spring section away from the conductor.  Because of the flexibility or springiness of the material of the flexed central spring section, a spring force is applied to assist in restraining the conductor in the slot.

Abstract: METHOD AND APPARATUS FOR FORMING A BASE FABRIC COMPOSED SOLELY OF        LONGITUDINAL YARNS Abstract of the Disclosure A method and apparatus for forming a base fabric composed solely of warp yarns to be used in making a papermaker's felt.  A plurality of yarns are drawn from a supply and wound around a pair of parallel drive rolls in a helical pattern by a travelling winding member. Two sets of parallel guide tines project from each end of the winding member.  The corresponding ends of a plurality of loops are attached to the trailing ends of the first set of tines and pass around the rolls and the opposite ends of the loops are attached to the leading ends of the second set of tines.  The yarns to be wound are attached to the trailing ends of the second set of tines.  As the rolls rotate, the winding member travels in an endless path around the rolls to draw the yarns from the supply and wind the yarns in a helical pattern.  A comb is located parallel to the rolls and the tines pass through the teeth of the comb to maintain proper spacing and order of the yarns as they are wound.

Title: Control of process aid used in hot water process for extraction of bitumen from tar sand

Abstract: "CONTROL OF PROCESS AID USED IN HOT WATER PROCESS      FOR EXTRACTION OF BITUMEN FROM TAR SAND"                       ABSTRACT OF THE DISCLOSURE            The hot water process is sensitive to the nature of the tar sand feed, which varies.  An alkaline process aid, usually NaOH, is normally added to the conditioning step of the process and is needed to obtain good bitumen recovery from most tar sand feeds.  The invention is based on the discovery that, for a particular extraction circuit used, there is a single value of free surfactant content in the aqueous phase of the process slurry which will yield maximum primary froth recovery regardless of the type of tar sand feed used.  The process in accordance with the invention therefore comprises:  (a) determining, for a single tar sand type and the extraction circuit used, the free surfactant content in the aqueous phase of the slurry, which will yield the maximum primary bitumen froth recovery; (b) monitoring the free surfactant content in the aqueous phase of the slurry during subsequent processing of various types of tar sand feed in said circuit; and (c) varying the process aid addition to the slurry as the nature of the tar sand feed varies, to maintain said free surfactant content sub-stantially at the level which leads to maximum primary bitumen froth recovery.

Abstract: ABSTRACT          A cooling device for use with a cryogenic cooling system to maintain a sample at cryogenic temperatures inside the vacuum chamber of a scanning electron microscope during observation is described.  The cooling device is made of a thermally conductive material and has a recess for mounting a sample holder, and a passage extending around the recess. A pair of flexible hoses are connected to opposite ends of the cooling device for permitting liquid nitrogen to flow through the passage.  By removing heat from the sample, sample holder and cooling device the liquid nitrogen vapourises and the vapour pressure produced causes vapour to flow out of the device and through one of the flexible hoses to remove heat from the sample and maintain it at a cryogenic temperature.  The hoses are corrugated and permit multidirectional movement of the cooling device.  In practice cryogenic temperatures as low as -190°C have been obtained.

Abstract: ABSTRACT          A process for the production of 2,6-di-tert-butyl-.alpha. methoxy-p-cresol and high molecular weight hindered phenols produced therefrom.  A process is disclosed for the production of the methyl ether of 2,6-di-tert-butyl-p-cresol in such a manner that allows subsequent production of 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene in the same pot.  The process permits substitution of the methanol solvent/reactant with a hydrocarbon or halogenated hydrocarbon solvent to produce the high molecular weight hindered phenol.          This aspect of the invention reduces production cost by eliminating expensive centrifugation associated with prior art processes.  The process also conserves catalyst by recycling it in the excess methanol.  The catalyst is a Mannich base such as 2,6-di-tert-butyl-.alpha.-dimethylamino-p-cresol formed from the reactants 2,6-di-tert-butylphenol and formaldehyde with dimethylamine.  The invention is an important improvement over prior art processes in that the production of bisphenol coproducts, notably 4,4'-methylenebis(2,6-di-tert-butylphenol) is low.

Abstract: DIGITAL SIGNAL SAMPLING SYSTEM WITH TWO       UNRELATED SAMPLING TIMEBASES                      Abstract A digital signal sampling system is disclosed for reconstructing the the relationship of digital data signals sampled by two sampling clock signals with different unrelated timebases,  The digital data signals sampled may be the same data signal or two different data signals sampled simultaneously in two separate sampler circuits at two different unrelated sampling clock freguencies or timebases to produce first and second sampled data signals.  A timebase correlation circuit produces first and second time correlation signals in the form of binary level signals in response to the receipt by a last clock pulse detector of first and second store clock signals which are derived from first and second sampling clock signals.  The time correlation signals indicate by their binary level the source of the last previous clock pulse of the first and second store clock  signals which was received by the timebase correlation circuit.  The timebase correlation signals and the first and second sampled data signals are stored in two acquisition memories connected to such sampler circuits, and are read out of the memories and together with a last clock pulse output of the correlation circuit are applied to a data signal reconstruction means including a digital computer which is programmed to reconstruct the digital data signals in time relationship and to display the reconstructed data signals on a cathode ray tube or other display device.
