Patent GB-201208916-D0 (GB)
Title: Separator device
Filed: 2012-05-21
Abstract: A separator device 10 for removing particles from suspension in a fluid comprising: a housing 12, having a central axis extending between first and second opposing ends; an inlet 34 and an outlet 36 provided in an end of the housing; a separation chamber 46 for separating solid particles from the fluid, including obstruction means to slow the flow of fluid within the chamber. Preferably the obstruction means includes curved walls forming concave collection areas for collection of particles.

Title: Artificial larynx
Inventor: KATZ PHILIP
IPC: A61F2/20
Filed: 1983-11-01
Granted: 1989-04-27
Abstract: The present invention provides a completely self-contained intraoral larynx comprising a power source, tongue activated controls, power saving signal generation circuitry, acoustic and audio amplifiers, and an intra-oral speaker. These components are contained within an otherwise conventional denture or dental prosthesis. The device produces a high amplitude sound while minimizing current drain from the power source. Laryngectomized patients require only short term training by a speech pathologist to use this device. Intelligible speech is usual within an hour of such training, and facility rapidly improves, The psychological barriers, post-operative physical limitations, aesthetic concerns and limited gestural communication traditionally associated with the use of extra-oral larynges is eliminated by the present invention.

Granted: 1991-12-12
Abstract: Biologically active blood serum glycoprotein (I) of molecular wt. about 90,000 and having at least 1 sialic acid moiety as biologically active site is new. (I) retains over one-half of its activity (causing T-cell growth factor prodn. in presence of interleukin-1 and T-lymphocytes) after being heated to 80 deg. for 30 mins. It has specific binding affinity to wheat germ agglutinin and "Cibacron" (RTM) blue A; and it lacks specific binding affinity to lysine. Glycoprotein (I) is a necessary cofactor with interleukin-1 in the biosynthesis of T-cell growth factor. Serum-free and mitogen-free interleukin-2 is obtd. by contacting a tissue culture of interleukin-1 and (I). For growth of T-cells in absence of blood serum a growth medium contg. cell nutrients and (I) as the only protein constituent is used; with this medium regulation of T-lymphocyte growth can be studied, and hepatitis risks are avoided.
