Abstract: ABSTRACT         A power-driven insertion tool for a helically coiled wire insert of the type used for tapped holes in parent material that is generally softer than a fastener being screwed into the tapped hole, whereby a mandrel having a threaded lead portion and a pivotal paw inserted in a groove below the threaded portion so that the paw engages a recess of the insert, in order that the insert may be screwed into the tapped hole.  A sleeve, concentric to the threaded mandrel, maintains the insert's helix angle for a smooth transition into the tapped hole.  An adjusting nut adjusts the depth to which an insert may be installed and whereby a free spinning bearing contacts the parent material and automatically reverses the torque of the tool.

Abstract: ABSTRACT     An improved preheater is provided suitable for use with  gas  or  oil  fired  reverberatory melting  furnaces  for recycling aluminum scrap and other scrap metals.  The improved preheater comprises a charge box having a bottom, and a chamber having a bed.  The chamber is in communication with the charge box at one end, and, an exit at the other.  A pusher is provided for pushing the contents of the charge box into the chamber and thus pushing the contents of the chamber towards the exit.  The chamber is of uniform expanding dimensions from its one end in communication with the charge box towards the exit.  The bed of the chamber carries openings therethrough from a gas chamber therebelow into which heated waste gas is passed for circulation through the openings in the bed through the contents of chamber.     A charging device is also provided in a Supplementary Disclosure of this invention which allows for charging of the reverberatory furnace.   The charge box has an open top and a pusher, a moveable plate supported for sliding movement in the charge box.  The moveable plate is provided to close off the top of the charge box when the pusher pushes the scrap metal towards the reverberatory furnace.   The moveable plate has a shearing edge at its leading edge which moves cooperatively with the pusher and shears any metal extending from the top of the charge box.  In preferred embodiment a verticle moveable plate is also provided which closes off the opening to the reverbatory furnace when the charge box opening is open for receiving scrap metal.

Abstract: ABSTRACT OF THE DISCLOSURE A process for manufacturing an edible food product includes making a mixture of sodium alginate, sodium caseinate and carrageenan, and adding this mixture to water at a temperature high enough to bring about substantially complete dissolution.  The resultant slurry is spread as a film on a surface, and heated to cause partial drying.  The film is then contacted by a solution of calcium chloride so that sodium atoms in the film are replaced by calcium atoms, thus adding strength to the film.

Abstract: CACHE DISABLE FOR A DATA PROCESSOR                         Abstract A data processor is adapted for operation with a memory containing a plurality of items of operating information for the data processor.  In addition a cache stores a selected number of all of the items of the operating information.  When the cache provides an item of operating information, the memory is not requested to provide the item so that a user of the data processor cannot detect the request for the item.  A disable circuit is provided to prevent the cache from providing the item when a signal external to the data processor is provided.  Consequently, a user, with the external signal, can cause the data processor to make all of its requests for items of operating information to the memory where these requests can be detected.

Abstract: ABSTRACT OF DISCLOSURE           A digital loudspeaking telephone for connection to a telephone line, comprised of a microphone, speaker, codec and digital signal processor.  Incoming and outgoing signals are received from remote and local subscribers respectively and in response, incoming and outgoing envelope and noise floor signal levels are generated and compared, and one of the incoming or outgoing signals is suppressed.  Automatic gain control of outgoing signals is implemented in order to allow smooth switching of the outgoing signals and to suppress background noise from being transmitted by the microphone.  The present invention also detects room echo and reverberation, and eliminates spurious channel switching due to echo signals in response thereto.

Granted: 1990-07-03
Abstract: ABSTRACT      A control coupling comprising an outer coupling part 1, an inner coupling part 2, a first set of annular plates 6 therebetween constituting a viscous shear coupling and a second set of annular plates 12 constituting a friction clutch, wherein a fluid tight axially movable piston 3 is disposed between the sets of plates, arranged to be movable axially to urge the plates 12 into torque transmitting engagement by expansion of the liquid in the viscous shear coupling.  The movement of the piston is limited by a stop 17, and springs 8 are interposed between the piston and friction clutch plates so that the maximum torque transmissible by the coupling is limited.  Under such conditions, the torque transmissible by the viscous shear coupling is negligible compared with that of the friction clutch.  The coupling may be utilized between axles of a motor vehicle, or in a differential unit.  in a further embodiment, Figure 4, the friction clutch may be electro-magnetically disengageable.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides an injection mold apparatus for plastic piece molding.  The apparatus includes male and female body parts and a gas blow-off ejection system for ejecting pieces formed on the male body part.  The blow-off system includes side and top opening vents in the male body part for initial release and slight lifting of the piece and a further bottom positioned final blow-off vent, which is covered by slideable means during introduction of the plastic to the mold to prevent the plastic from flowing into the final blow-off vent and which is only exposed when required for completing blowing of the piece from the male body part.  The slideable means has a slide tolerance to substantially eliminate flowing of the mold material therearound while being readily slideable when required for exposure of the blow-off vent to the male body part.

Abstract: ABSTRACT        A  stereophonic  broadcasting  system  incorporating companding of the difference signal in which both the usu-al difference signal and a compressed version of the dif-ference signal are transmitted to one or more remote re-ceivers.  At the receiver the usual, unchanged, difference signal is used as a reference signal for controlling the expansion of the compressed difference signal  so as to cause the amplitude of the companded difference to equal the level of the usual difference signal.   Thus, the ex-pander is adaptive to any compression characteristic that might be employed at the transmitter.  Further, the avail-ability of the usual uncompressed difference signal at the receiver enables the adaptive decoding of dynamic parame-ters of the received signal, such as frequency response and attack and recovery times, so that all of the parame-ters of the original signal can be restored automatical-ly.

Abstract: ABSTRACT OF THE DISCLOSURE          A reverse hydrocyclone cleaner for removing light contaminants from pulp slurry has a housing defining a hydrocyclone separating chamber.  Pulp slurry is fed into the separating chamber adjacent an upper end thereof to form an outer helically and downwardly moving slurry stream relatively free from light contaminants, an inner pulp stream containing a substantial amount of  the light contaminants and an air core within  the inner stream. An overflow orifice is located adjacent an upper end of the separating chamber, and an underflow orifice is located adjacent a lower end of the separating chamber to remove the outer pulp stream relatively free from light contami-nants.  A centrally located blocking finger is located in the underflow orifice.  The outer pulp stream passes around the blocking finger, which has a substantially flat upper surface of sufficient diameter to define lower limits of both the air core and the inner pulp stream and cause the inner pulp stream containing a substantial amount of  the light contaminants to travel upwardly in the separating chamber in a helical manner around the air core to and through the overflow orifice.
