Abstract: ABSTRACT OF THE DISCLOSURE The process of the invention is directed to an improvement in purifying cyanuric acid which contains as a contaminant, an enclosed residue of sulpholane used in the reaction medium to produce cyanuric acid from urea, biuret or mixtures thereof.  The process comprises suspending the impure cyanuric acid in an aqueous medium and stirring.  As a result of the process, cyanuric acid is substantially freed from enclosed residues of sulpholane.

Abstract: ABSTRACT             A flexible, permeable seaming tape is treated by saturating one side with a liquid adhesive, which is allowed to dry so that the adhesive becomes inactive or non-tacky, thereby enabling the coated tape to be easily handled, coiled, ect.  To seam together two carpet sections a strip of the tape is placed on a surface adhesive-side-up.  The undersides of the sections adjacent the edges to be joined are coated with a liquid adhesive similar to that applied to the tape, and while still tacky, are urged down-wardly against the tape with their edges in abutting relation.      The still-damp adhesive on the carpet dissolves or reactivates the dry adhesive in the tape to form, when dried, a strong co-hesive bond between the tape and carpet.  The tape may comprise a single layer of non-woven material, or a non-woven material secured to a fiber matrix which resists lateral stretching.

Title: Granular calcium hypochlorite coated with an alkaline earth metal hypochlorite by spray graining
Inventor: SAEMAN WALTER C
IPC: B01J13/04

Granted: 1979-12-11
Abstract: ABSTRACT OF THE DISCLOSURE      Granular calcium hypochlorite particles having a core of calcium hypochlorite encapsulated in a plurality of layers of calcium hypochlorite are produced from an aqueous slurry of calcium hypochlorite by spraying a pumpable and sprayable slurry of calcium hypochlorite particles onto suspended particles of solid calcium hypochlorite above a moving bed of said particles.  The solid particles coated with the slurry are heated to simultaneously evaporate and remove water from the slurry whereby said particles are coated with a layer of solid calcium hypochlorite.    A portion of the moving bed of coated particles is removed from the spraying zone and further processed, if desired.  In one embodiment, the coated particles with or without sizing, are dried to produce granular particles having the, desired moisture content.  In another embodiment, calcium hypochlorite particles such as the withdrawn portion are conveyed to another spraying zone where the particles are coated with another alkaline earth metal hypochlorite such as a slurry of calcium hypochlorite having a lower available chlorine content than the particles which form the core material.  In another embodiment, the coated calcium hypochlorite particles are conveyed to another spraying zone where the particles are coated with a plurality of layers of another inorganic salt.     The resulting coated or layered granular particles of calcium hypochlorite have a high level of integrity and resist degradation and dusting when subjected to rather severe handling conditions.  In addition, the novel coated granular calcium hypochlorite particles of this invention are highly stable when contacted with lighted cigarettes, organic materials and the like.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved spring controlled poppet-type cushion for a fluid piston-cylinder device, wherein the cushion is connected to the piston by spring means and aligned with the inlet-exhaust opening at the end of the cylinder.  The improved cushion includes retaining structure for holding the spring associated with it in axial alignment with the opening for receipt therein as the piston approaches the end of the cylinder.  This permits the piston to move into contact with the wall without interference from the spring.  The sealing of the cushion within the opening in the end of the cylinder is effected at a point spaced axially from the piston when the latter is in contact with the end wall to provide an axial spacing between the cushion and piston.

Abstract: ULTRASONIC WAVE RADIATION PATTERN DISPLAY SYSTEM INCORPORATING PHASE CONTRAST MEANS            Abstract of the Disclosure The present system permits image of internal structure of ultrasonic wave scattering object to be visually revealed on a cathode ray tube display with good contrast and good resolution, even when acoustic attenuation characteristics of object are relatively uniform and scattering points in object are due substantially to differences in acoustic index of refraction.  This is accomplished by employing an acoustic quarter-wave plate to relatively phase shift unscattered wave energy passed through object with respect to scattered wave energy passed through object, thereby transforming a phase pattern manifesting the object's internal structure into an intensity image pattern thereof which insonifies a flexible pellicle mirror. The remainder of the system converts this pattern into a visual display on the cathode ray tube.

Abstract: MEMORY CONTROL SYSTEM Abstract of the Disclosure A group of asynchronous memories are interconnected to a CPU and the I/O terminal (data channel) in a minicomputer. The memories send "handshaking" signals to the data channel and the CPU by means of a common signalling system having common signal-ling lines, one line to the data channel and one line to the CPU, to define the status of any of the memories, depending on the memory which  is addressed, by acknowledging requests by that memory, with respect to a data bus and indicating receipt of data by the memory.  The CPU and data channel in turn, signal each of the memories by means of a common set of signal lines to determine each memory's status and to cause the output of the aforementioned memory signals.

Abstract: MASSAGE APPARATUS      Abstract A massage unit designed to produce percussive directional stroking for medical purposes such as:  to loosen and to mobilize, in a selected direction, bronchial secretions or other congestive material in humans or animals; to improve blood circulation, and; to relax muscles, has a portable housing that houses a motor which transmits rotary power through a swivel coupling assembly attached to the housing through a drive cable to an eccentric weight housed within a palm-sized applicator head having a resilient applicator pad to be applied to the chest, back, arms, legs or other parts of a patient's body.  The eccentric weight rotates freely within the head to cause the applicator pad to transmit a percussive directional stroking force to the body. The resultant force transmitted to the body has two components material, and one force component parallel to the body to mobilize loosened congestive material in a selected direction.  The applicator head is compact and shaped to be easily held with one hand and to allow the patient to lie on it for therapy with minimal discomfort. An arrow on the applicator head indicates the direction of the impulse transmitted to the patient by the eccentric weight, and a belt unit is supplied to support and hold the applicator head firmly against the body to allow an individual patient to self-administer treatments in difficult-to-reach locations on his own body, such as his back or sides. Foam pads which encase the applicator head are also supplied to minimize the transmission of vibration to the user's hand or therapist's hand, and to permit the patient to lie more comfortably on the applicator head during therapy.
