Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for making frozen food products, particu-larly ice cream or the like, in which the apparatus can be inter-changeable with the existing ice dispenser unit in the freezer compartment of a domestic refrigerator provided with an auto-matic ice maker unit.  The apparatus includes: a housing for con-taining the frozen food product mix; stirring means disposed with-in the housing for stirring the mix during convection heat ex-change between the mix and the interior of the freezer compart-ment; a drive asembly for detachably connecting the stirring means to a drive motor, and a user operating timer assembly for actuating the drive motor to operate for a predetermined period of time in accordance with the desired consistency of the final product.  A switch assembly is preferably incorporated in the circuitry of the refrigerator for direct activation by the time assembly for the dual purpose of operating the drive motor and placing the refrigerator compressor in continuous operation.  An integral timer is preferably disposed in the switch assembly circuit for causing cyclical operation of the drive motor to prevent failure of that motor which might otherwise occur during its continuous operation.

Abstract: METHOD AND APPARATUS FOR WASHING PAPER PULP     ABSTRACT OF THE DISCLOSURE The washing efficiency for removal of cooking and bleaching chemicals from cellulose paper pulp on rotary vacuum filters is improved by disrupting the filter mat with a low volume, directly impinged flow of wash liquor applied intermediately of soft, displacement wash liquor applications.  No additional wash liquor is allocated for respective wash stages but the mat disturbing flow volume is deducted from the predetermined requirement with the remainder divided in substantially equal proportions applied before and after the mat disturbing application.

Abstract: FREEZEPROOF VALVE ASSEMBLY              ABSTRACT OF THE DISCLOSURE           An improved freezeproof valve assembly is provided for a water hydrant, such as an outdoor drink-ing fountain or the like.  The valve assembly comprises a sump housing for installation below the ground frost line and for connection between a water supply pipe and a standpipe, the latter being coupled in turn to a fountain bubbler head or the like.  A control valve within the sump housing  is opened pneumatically upon depression of an actuator button on the fountain to permit water flow from the supply pipe through a main jet pump which draws an induced water flow from within the sump housing through an induction port thereby providing a combined water flow through the standpipe to the bubbler head.  This combined water flow is maintain-ed substantially constant by a float-activated refill valve which permits a refill water flow from the supply pipe into the sump housing sufficient to maintain the housing water level above the main jet pump induction port.   This refill water flow passes through a refill jet pump having an induction port through which a vacuum is drawn within a control line for pneumatically closing the control valve when the actuator button is released. When the control valve is closed, water within the standpipe drains  through the main jet pump induction port into the sump housing.

Title: Method for desulfurization, denitrification and  oxidation of carbonaceous fuels

IPC: C10J3/57

Abstract: ABSTRACT OF THE DISCLOSURE          A method for desulfurization, denitrification, and oxidation of carbonaceous fuels including a two stage oxida-tion technique.  The carbonaceous fuel, containing ash, along with an oxygen-containing gas is introduced into a first stage partial oxidation unit containing a molten ash slag maintained at a temperature of about 2200°  -  2600°  F.  A flux may also be introduced into the first stage partial oxidation unit for the purpose of increasing the basicity and maintaining the viscosity of the molten ash slag at a value no greater than about 10 poise. The carbonaceous fuel is gasified, and sulfur is chemically bound and captured in the molten ash slag.  Since the first stage is operated in a gasification mode (reducing atmosphere), essentially all of the nitrogen in the fuel is converted to diatomic nitrogen, which results in a low nitro-gen oxide emissions upon final combustion.  The first stage is also designed to physically remove a major portion of the fuel ash, the ash leaving the system as a molten slag.  The combustible gas derived from partial oxidation (gasification) is directed along a substantially horizontal path to a second stage oxidation unit for final combustion.  The sulfur-containing molten slag is removed to a water-sealed quench system or indirect water cooled system for disposal.

Abstract: TAPE DRIVE CLOSURE OPERATOR     ABSTRACT OF THE DISCLOSURE          A closure operator such as a garage door oper-ator utilizes an apertured flexible tape.  The tape is enclosed in a guide and a drive sprocket has teeth engag-ing the apertures to apply both tension and compression forces to open and close a door.  The apertures are en-larged in width and length and the tape has fewer aper-tures per-unit-length compared to the prior art tape.          This decreases the stress per-unit-area in the tape at each tooth and increases the shear strength of the webs between successive apertures to be more nearly equal to the tensile strength of the tension band areas of the tape.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: Abstract A test for the presence of occult blood in fecal matter or other bodily substance empolys an indicator wipe 2. The indicator wipe 2 has an occult-blood detection-test surface 10 for collecting a specimen and includes a peroxidase-activity indicator reagent dispersed on or located proximate to the specimen collection region.  The test involves contacting the specimen-collection region to the bodily substance to obtain a specimen, then applying an oxidizing-agent developing fluid to the specimen and observing any color change to determine if the specimen contains occult blood, and finally disposing of the indicator wipe by placing it in a toilet bowl and flushing it away.

Abstract: ABSTRACT     Human melanocyte cells are grown in tissue culture medium containing fibroblast growth suppressor plus tumor growth promoters at pH 7.2 to about 7.4.  In a stepwise procedure, Langerhans, keratinocytes and most fibroblasts are removed in the presence of the above suppressor and promoter followed by a subsequent trypsinization treatment.          In a final purification step, remaining fibroblasts are separated from the melanocytes by reacting the cell mixture with monoclonal antibody specific for melanocytes, and then separating out the melanocytes from the fibroblasts on density gradients.

Abstract: TITLE CIRCUIT TO MINIMIZE LOCAL CLOCK FREQUENCY     DISTURBANCES WHEN PHASE LOCKING TO A     REFERENCE CLOCK CIRCUIT        ABSTRACT OF THE DISCLOSURE A frequency disturbance minimization circuit for use in a phase locked loop circuit.  A pulse gen-erator eliminates random phase shift, which occurs after a reference clock outage, by synchronizing counted down derivatives of the local and reference clock cir-cuits.  A window circuit provides a signal representa-tive of the difference in phase between these local and reference clock circuits.  A counter accumulates these phase difference window signals for periodic interroga-tion by a microprocessor which causes a voltage con-trolled oscillator to adjust its frequency in the direction necessary to eliminate this phase difference.

The piston is in the form of a plate (21) having a short peripheral flange (22), the external face of which assures only relative guidance by engaging the cylinder with a play sufficiently great as to reserve a passage (3) for the gas supplied via the feed opening sufficient to allow this gas to reach the space and a medial flange (23), the edge of which has a bearing surface the shape of which is complementary to that of the seat (9) with which it cooperates in order to close the discharge passage. The valve is particularly adapted for improving the outflow of products at the outlet of silos.
