Abstract: ABSTRACT   1.      An aqueous coating composition which comprises (a)    a dispersion in an aqueous medium of a product obtained by mixing as the sole film-forming components of the mixture and heating, (i)     an epoxy-amine adduct having ionizable nitrogen-containing groups, and (ii)    a crosslinking agent for the adduct which is free from carboxyl groups selected from phenol/formaldehyde and aminoplast resins, or blends of these resins to effect an increase in viscosity of the initial mixture of (i) and (ii), and (b)   an acid which is capable of ionising the nitrogen-containing groups in the product defined in (a), there being present sufficient of said acid to neutralise at least 30% of the nitrogen-containing groups in and form a stable dispersion of said product in the aqueous medium.          The composition has improved stability at high pH values and at elevated temperatures and is particularly suitable for cathodic deposition.

Title: Low-temperature steam desorbate process for improved  instant tea

Abstract: IMPROVED LOW-TEMPERATURE STEAM DESORBATE PROCESS FOR IMPROVED INSTANT TEA                        Abstract A stable water-soluble Desorbate instant tea having a flavor, aroma, appearance and chemical composi-tion approximating that of fresh expertly brewed tea is made by a process comprising passing steam at reduced pressures through a columnar bed of ground tea leaves to pre-wet and pre-swell an upper portion of said leaves; and then passing water and wet steam at reduced pressures and low temperatures through said bed to desorb and extract from said tea leaves an aqueous tea extract while maintaining a weight ratio of said extract to dry tea leaves of from about 0.5:1 to about 3:1, and collecting said extract in a cold trap.  Decreaming of the extract prepared by this process is not necessary to provide a water-soluble dry instant tea which, upon reconstitution in water, provides an iced beverage that tastes like an iced tea made from fresh, expertly brewed tea.  The solu-bility and solution stability of the Desorbate tea of this invention are surprisingly improved by treat-ing the process water with a minor amount of a higher chain polyphosphate glass, a bisulfite, a sulfite and/or a suitable carrageenan.

Abstract: La présente invention concerne une méthode de régulation du chauffage d'au moins une enceinte de stockage de calories par un fluide caloporteur. Selon cette méthode, on fait circuler le fluide caloporteur dans un circuit à l'intérieur duquel il reçoit d'abord des calories d'une source de chaleur, puis cède ses calories à une enceinte de stockage de calories. La circulation du fluide est commandée en fonction de la température tA du fluide à la sortie de la source de chaleur, d'une température tB au voisinage de l'entrée de l'enceinte et de la température tC du fluide à la sortie de l'enceinte. Cette circulation de fluide est arrêtée au moins dans l'enceinte lorsque la température tA est inférieure à la température tB et lorsque la température tB est inférieure ou égale à la température tC même si la température tA est supérieure aux températures tB et tC. Cette méthode est caractérisée en ce que la température tB est la température du fluide arrivant de la source de chaleur à l'entrée de l'enceinte, extérieurement et en contact thermique avec celle-ci. La présente invention concerne également un dispositif pour mettre en oeuvre la méthode selon l'invention. Application à la production d'eau sanitaire.

Title: Idling and air replenishing system for a  reciprocating hammer mechanism
Inventor: SIDES DANIEL H
IPC: B25D11/06

Granted: 1982-07-27
Abstract: ABSTRACT    There is described in this disclosure, an improved air re-plenishing and idling system for a reciprocating hammer type tool having an outer housing and reciprocal drive means which comprises an elongated barrel mounted within that housing.  The barrel in-cludes an axially disposed, air passageway means.  Slideably positioned within the barrel is a piston member which includes a closed end portion and a hollow, tubular forward portion having first and second air passageways.  The piston is reciprocally moved within the barrel by the drive means.  Slideably positioned within the hollow tubular portion of the piston is an impact ram.          In the operational mode, the ram, tubular portion of the piston member, and barrel cooperate to seal or expose the first and second air passageways and provide a communicative path to the "outside" air through the barrel air passageway means whereby the ram is urged axially towards and away from the tool bit through the pressure differentials created.  Further, in the idling mode, the first and second air passageways and the barrel passageway means insure that the ram is inactive when the tool bit is re-moved or when the tool is lifted from the work surface.

Abstract: BRAKING METHOD AND APPARATUS FOR VIBRATORY FEEDER                            ABSTRACT         A material dispensing apparatus including drive means fur driving a feeder bowl is disclosed.  A control circuit for controlling the drive includes a Hall effect amplitude sensing transducer for monitoring the magnitude of bowl vibrations and a braking circuit for controlling the damping of vibratory motion after the requisite amount of material has been fed from the feeder bowl.  The braking circuit selectively reverses the current flow through a drive coil which comprises a portion of the drive circuitry of the apparatus.  This current reversal disrupts the rhythm of forced oscillations which feed material from the bowl and causes bowl motion to be damped.  A mechanical brake coupled to the bowl complements the braking action of braking circuit and locks the bowl in place to prevent accidental dispensing of parts.
