Title: Osteoinductive protein mixtures and purification processes
Inventor: POSER JAMES W
IPC: A61F2/00
Filed: 1992-04-21
Abstract: A method for purifying bone-derived osteoinductive factors including an ultrafiltration process, an anion exchange pro-cess, a cation exchange process, and a reverse phase HPLC process. The ultrafiltration process preferably includes a first ultrafil-tration step using a membrane having a nominal molecular weight cutoff of approximately 100 kilodaltons (kD) and a second ul-trafiltration step employing a membrane having a nominal molecular weight cutoff of approximately 10 kD. For the anion exchange process, a strongly cationic resin is used, preferably having quaternary amine functional groups. Typically, the eluant for the anion exchange process has a conductivity from about 10,260 micromhos (µmhos) (1.026 x 10-2 siemens (S)) to about 11;200 µmhos (1:120 x 10-2S). For the ration exchange process, a strongly anionic resin is used, preferably having sulfonic acid functional groups. The eluant for the ration exchange process typically has a conductivity from about 39,100 µmhos (3.91 x 10-2S) to about 52;700 µmhos (8:27 x 10-2S) or more. The HPLC  process typically utilizes a column containing hydro-carbon-modified silica packing material. The osteoinductive proteins can be eluted from the HPLC column with an acetoni-trile solution in combination with aqueous trifluoracetic acid. The purification processes yield osteoinductively active pro-tein mixtures.

Patent CA-2110809-A1 (CA)
Title: Salt composition containing calcium magnesium acetate and sodium silicate
Inventor: SIMPER JACK L
IPC: C09K3/18
Filed: 1992-03-05
Abstract: The inventive composition contains salt, calcium magnesium acetate (CMA) and sodium silicate, and may optionally contain sodium ferrocyanide, diatomaceous earth, and/or other materials. The composition is useful for facilitating the melting and removal of snow and ice, and is stable and non-corrosive. The inclusion of both CMA and sodium silicate in the salt composition provides better corrosion resistance than can be obtained by the inclusion of comparable quantities of either CMA or sodium silicate alone. The inventive salt composition is considerably less expensive to manufacture than CMA-containing salt compositions which provide comparable corrosion resistance.

Patent CA-2130346-A1 (CA)
Title: Capillary reference half-cell
Inventor: HALL STEPHEN H
IPC: G01N27/30
Filed: 1993-04-14
Abstract: The present invention is a reference half-cell electrode wherein intermingling of test fluid with reference fluid does not affect the performance of the reference half-cell over a long time. This intermingling reference half-cell may be used as a single or double junction submersible or surface reference electrode. The intermingling reference half-cell relies on a capillary tube having a first end open to reference fluid and a second end open to test fluid wherein the small diameter of the capillary tube limits free motion of fluid within the capil-lary to diffusion. The electrode is placed near the first end of the capillary in contact with the reference fluid. The method of operation of the present invention begins with filling the capil-lary tube with a reference solution. After closing the first end of the capillary, the capillary tube may be fully submerged or partially submerged with the second open end inserted into test fluid. Since the electrode is placed near the first end of the capillary, and since the test fluid may intermingle with the reference fluid through the second open end only by diffusion, this intermingling capillary reference half-cell provides a stable voltage potential for long time periods.

Title: Reignition device for a gas burner
Inventor: HIMMEL ROBERT L
IPC: F24C3/10
Filed: 1993-03-05
Abstract: A reignition device (32) for a gas burner includes a reig-nition flame chamber (31) which opens into a burner face of the gas burner. The burner face is also provided with a plurality of circumferentially spaced burner ports (28, 29). The reignition chamber (31) includes at least one port (98) for receiving an air/gas mixture flowing within the burner head. A reignition flame is initially ignited at the reignition chamber by a burner port flame or an electrode (47) which also can be used to ignite the gas flowing out of the various burner ports (28, 29) in the burner face. The reignition device (32) is designed so that the reignition flame burns in a balanced and stable manner both when the burner is set at a high rate and when the gas burner is turned down to a low setting. Subsequently, should the flames about the burner face be extinguished by an external influence, the reignition flame will remain ignited and will function to reignite the burner flame.

Title: Method for starting gas discharge lighting systems and starting circuitry therefore
Inventor: BOGDAN ALEXEY
IPC: H05B41/26
Filed: 1994-09-22
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a new method of starting an operating circuit for gas discharge lighting systems, in particular fluorescent lighting, and the starting circuitry therefore. The circuit is generally improved and provides for totally adjustable start which occurs in three-stages. The circuit is also designed to meet all current and future criteria for rapid start ballasts. In the first stage of the start, the power supply and inverter operate are fully operational, and a small of amount of current is applied to the lamps to provided a preheat period. In the second stage, the preconverter is fully activated and capacitive elements in the preconverter become fully charged. In the third and final stage, the switching element in the start circuit switches on, allowing full voltage to be applied across the output. Thus all main circuit elements are stabilized prior to full voltage being applied to the bulbs, allowing a very short time for stabilization of lamp arc current. 28

Title: Recycling of natural and synthetic rubber
Inventor: SEKHAR BALACHANDRA C
IPC: B29B/
Filed: 1994-10-24
Abstract: A process of recycling used sulphur-cured elastomeric materials comprising masticating the said elastomeric materials at temperatures below 40°C with a chemical paste which is capable of initiating proton exchange in a controlled manner and thereby open up or delink the vulcanised network of the elastomeric materials. The chemical paste is made from the zinc salt of dimethydithiocarbamate and mercaptobenzothiazole in the molar ratio in the range of 1:1 to 1:12 dispersed in diols and in the presence of stearic acid, zinc oxide and sulphur. This mixture, which may be termed the 'paste', when blended with tyre crumbs or any other vulcanised crumbs in concentrations of 6 parts binder per 100 parts of rubber crumbs on a mill effectively delinks the vulcanised network and renders the compound ready for moulding and vulcanization. The total milling period, which occurs at temperatures below 40°C, takes only 7 to 10 minutes. Alternatively, the binder and tyre crumbs could be first mixed in an intermix and subsequently milled in an open mill.   The obtained recycled rubber compounds display satisfactory level of physical and dynamic characteristics. Such compounds can be directly used in moulded goods or in admixture with fresh compounds in tyres and related areas.

Title: Computer operating system providing means for formatting information in accordance with specified cultural preferences
Inventor: MILLER GARY W
IPC: G06F9/40
Filed: 1995-03-30
Abstract: A system is disclosed for presenting information which reflects the users' cultural preference, including language and other conventions, that can manage locale categories without requiring application programs to manage all the overhead of repetitive changes to locale category values. Users merely specify their cultural preferences through the application programs and the operating system assigns a stack from the working memory for each specified category of cultural preference, and pushes onto the stack the location in the working memory of a file for the category of cultural preference specified, the file having been transferred from a locale database of files that contain code formatting according to the cultural preferences. In a second aspect of the operating system, multiple concurrent sets of cultural preferences are handled by determining whether a location in the working memory corresponding to the preference specified is currently in the queue, and if not, by placing a new value in the queue for each memory location corresponding to an additional set of locale category values.
