Title: Valve for discharging powders of a stirred ball mill
Inventor: MATHIEU SIMON
IPC: F16K3/26
Filed: 2002-07-03
Abstract: The invention concerns a valve for discharging powders prepared in a stirred ball mill comprising a crucible provided with an inner wall and wherein the balls are driven. Said valve comprises a body mounted sliding in a sleeve opening into the crucible of the stirred ball mill. Said body has one front end in the form of a wall configured in a manner to merge with the inner wall of the mill when the valve is in closed position. A hole is perforated in the valve body to enable the passage of powder to be discharged by means of a carrier gas from an inlet arranged proximate to the front end of the body towards an outlet arranged downstream and connected to a collecting system. Said inlet consists of a set of side openings which are arranged  beneath the front end of the body and are of dimension selected for enabling the powders to allow the powder flow through the hole of the body while pushing back the balls into the crucible of the mill. The valve further comprises a device for moving and retaining the body inside the sleeve between said closed position wherein the front end of the body merges with the inner wall, and an open position wherein the body is in extended position inside the crucible so as to release its inlet and enable the powders and the carrier gas to penetrate into the side openings and reach the outlet of the body via the hole perforated therein.

Title: Muffler for a compressed air driven motor
Inventor: REEVES ERIC
IPC: F01N1/08
Filed: 1989-11-10
Abstract: MUFFLER FOR A COMPRESSED AIR DRIVEN MOTOR          Abstract of the Disclosure:        A sound absorbing muffler for a compressed air driven motor has first and second mutually confronting end walls connected by four side walls.  A pad of sound absorb-ing material constructed from SAE No. F-7 polyester felt is contained in the muffler housing.  An entrance port at the center of the first end wall supplies exhaust to the interior volume of the muffler housing.  A series of depressions in the first end wall disperse the exhaust over a first planar surface of the pad of sound absorbing material.  The porosity of the sound absorbing material permits the exhaust along with grease, oil or water carried by the exhaust to pass through the pad.  The exhaust exits a second planar surface of the pad at the second end wall of the muffler housing and is discharged from the interior volume of the muffler housing through a plurality of louvers provided in the second wall of the muffler housing.  The sound absorbing muffler provides a compact muffler of reduced size that adequately silences the exhaust of the air motor and does not appreciably restrict the flow of the exhaust through the muffler.

Title: Secure transmission in remote control and supervision system
Inventor: BEZOS ANGEL P
IPC: B61L23/02
Filed: 1990-02-12
Abstract: SECURE TRANSMISSION FOR REMOTE CONTROL    AND SUPERVISION SYSTEMS            ABSTRACT OF THE DISCLOSURE      A transmission protocol for use in transmitting commands to an end of train (EOT) device controls a train's brake system.  A head of train (HOT) device, typically located in the locomotive cab, is provided with a thumbwheel switch for inputting numbers which identify the EOT device.  In the simplest implementation, the EOT device will respond to any HOT that dials its number and it will do whatever it is told to do. To prevent dangerous commands from being executed in error, either several repetitions of the command must be sent to the EOT device by the HOT device within a predetermined period of time before the command, or the command takes the form of a very large predefined number or a combination of the two.  The next level of security requires only a minimum increase in circuit complexity.  A memory is added to the EOT device and a unique ID number is assigned to the HOT device.  The HOT unique ID is communicated to the EOT device during an arming sequence, and the unique ID is imbedded in the memory of the EOT.  Once armed, with the HOT unique ID stored in the memory, the EOT device will respond only to that particular HOT device. Security is increased by replacing the unique ID of the HOT device with a "password".  The password can consist of a very large (32 bits) number that has the mathematical characteristic of being the product of one unique pair of prime numbers.

Title: Large-scale fermenter inoculation with frozen cells
Inventor: SCHWARTZ BARRY D
IPC: C12N5/071
Filed: 1990-04-27
Abstract: An improved method of inoculating large scale fermenters with mammalian cells is provided. Instead of taking one or more ampules of frozen cells through a series of scale up steps in tissue culture flasks and/or roller bottles, the cells are inoculated into a small fermenter in advance of their anticipated usage in fermenter inoculation. The cells are concentrated and dispensed into approximately 500 ml aliquots (or larger) and mixed with a cryopreservative solution. The aliquots are frozen in liquid nitrogen in specially designed freezer bags. The cells can thus be held indefinitely. When a fermenter run is to be initiated, a cell bag can simply be thawed and inoculated into the fermenter. Because the cells have been previously adapted to the fermenter medium, cell growth and production begin almost immediately after inoculation.
