Abstract: ABSTRACT          COMMINUTION OF MATERIAL     Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor.  During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber.  Pulses of gas are directed periodical-ly at the material through inlets (15) to prevent agglomeration of the material.  The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8).  Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.

Abstract: An automatic transfer device and process enable the transferring of a continuously supplied yarn from a first take-up tube (which usually has a full package thereon) to a second take-up tube, which has usually no yarn thereon.  In carrying out this process, the apparatus automatically cuts and aspirates the continuously supplied yarn, and an actuator arm applies the yarn to the second take-up tube by moving the continuously-supplied yarn into contact with a yarn snagging device.

Abstract: The signal processor includes a field or frame store (24). If a video signal having a non-standard relationship between its line frequency (fH) and its color subcarrier frequency (fSC) is processed, corresponding signal samples from an analog-to-digital converter (12) of successive fields or frames are misaligned in the store, leading to a degradation of the processed signal. A nonstandard signal detector (22, 19, 23, 21) produces a control signal indicative of the existance of the non-standard relationship and the mode of operation of the processor is controlled accordingly. In one example, field or frame processing and line processing are selectively performed depending on the control signal, line processing being performed in the presence of the non-standard signal.

Abstract: The polymerization of alpha-olefins in a gas phase involves the problem of agglomeration of the product into particles disadvantageous from the viewpoint of its handling. In the present invention this problem has been solved by means of a new type of process for the homo- or copolymerization of alpha-olefins. In the process the catalyst system is pretreated by contacting and reacting a transition-metal compound which is solid or on a solid carrier with an organoaluminum compound, and possibly an electron donor, in a liquid medium, and by drying the thus formed reaction product to produce a solid catalyst system. The thus pretreated solid and active catalyst system is then fed together with an alpha-olefin in the gaseous state into a gas-phase reactor, and polymerization is carried out by contacting them with each other. By feeding a dry and active catalyst system into the gas-phase reactor, it is possible to avoid the agglomeration of the product which occurs in conventional processes in which an organoaluminum compound and possibly an electron donor are fed in a liquid medium into the reactor.

Abstract: The security device of the invention comprises a movable organ in the interior of a cage mounted for rotation with respect to the body of a projectile, the movable organ being temporarily blocked from such rotation around the axis of gyration by at least one pin ejectable under the action of centrifugal force. Said pin is itself retained by an elastic spiral band enrolled upon the cage and which, as a result of a difference introduced into the speeds of respective rotation of the cage and of the body around the axis of gyration upon the exit of the projectile from the muzzle of the weapon, unwinds to liberate the pin. As a result, the movable organ after a trajectory of many tens of meters after the projectile has left the muzzle of the barrel of the weapon completes the pyrotechnic train which fires the projectile.

Abstract: A process and apparatus for grinding the proper taper and all of the flutes with the correct number of spirals simultaneously in a single cycle of the grinding machine. This is accomplished by passing a rotating stock to produce the correct number of spirals under a grinding wheel that is dressed with three or four properly formed ribs depending on how many flutes are being manufactured. These ribs are spaced so as to exactly match the lead distance of the rotating stock during 120° or 90° of revolution, depending on whether a three or four fluted instrument is being manufactured. The height of each individual rib on the grinding wheel varies in relationship with each other to exactly match the correct taper being created by moving either the rotating stock portion of the machine or the grinding wheel portion of the machine so as to increase the distance therebetween.

Granted: 1993-07-20
Abstract: Abstract of the Disclosure A system for purification of refrigerant within a storage  container  includes  a  filter/dryer  for  removing contaminants' from refrigerant passing therethrough,  and a refrigerant pump connected to the storage container to circulate refrigerant in a closed path from the container through the filter/dryer and return the refrigerant to the container.  The system configuration is such that the refrigerant is in liquid phase in at least a portion of the closed path.  A pressure-differential valve has an inlet coupled to a purge port on the container for receiving air captured within the container.          Container air pressure at the valve inlet is fed to one side of a flexible diaphragm.  Circulating liquid refrigerant is passed in heat transfer contact with a sealed enclosure containing liquid refrigerant, so that the refrigerant within the enclosure is at saturation pressure and acts on the opposing side of the diaphragm in conjunction with a valve spring.  The diaphragm is coupled to a valve element that lifts from a valve seat to connect the valve inlet to an outlet, and thereby vent air from within the storage container, whenever container air pressure exceeds refrigerant saturation pressure by a threshold that is determined in part by the valve spring.
