Patent CA-2098134-A1 (CA)
Title: Treatment of sewage sludge
Inventor: BEZUIDENHOUT FRANS F
IPC: C05F17/00
Filed: 1993-06-10
Abstract: ABSTRACT            Sewage sludge is mixed with organic material such as woodchips in a three screw mixer so that moving masses are created in the mixing compartment, there being a shearing action at the interfaces between the masses. The mixer includes the mixing compartment and a holding compartment into which dewatered sludge is continuously charged.  There is a gate between the compartments which is opened when it is desired to convey sludge from the holding compartment to the mixing compartment.  The shearing action results in the organic material being coated with a thin layer of sludge without the formation of dewatered sludge lumps which would rot instead of composting.

Patent CA-2102936-A1 (CA)
Inventor: LEONE PASQUALE
IPC: H03H17/06
Filed: 1993-11-12
Abstract: Digital samples of e.g. video data to be displayed on a computer monitor is processed by a video graphics circuit, which has the task of both aligning samples provided by an asynchronous sampler, and blending those samples, which usually suffer a series of the degrading effect as a low pass filter. The present invention describe a circuit that combines a sample aligner and a sample blender into one circuit in which the sample data passes through only one filter, and thus suffers only one low pass effect. In addition, only two multipliers, one delay, and one adder are required, instead of double the number as would be required by using the prior art. The total amount of circuitry is thus reduced and the quality of the resulting signal is improved.

Title: Cryosurgical spraying apparatus
Inventor: SANDLIN FELIX W
IPC: A61B18/02
Filed: 1992-03-09
Abstract: An insulated, compact, mobile cryosurgical instrument (11) is provided that has no moving parts in contact with a liquefied gas coolant retained in an insulated container. Upon interrupting normal venting from the container, the liquefied gas coolant will build up a pressure in the container which may be increased by a squeeze pressure device (35). That pressure will cause the liquefied gas coolant to spray from a nozzle (44) until normal venting is restored.

Title: An agent as a processing aid, a mineral wool needle-felt, a crimped mineral wool product, and methods for producing them
Inventor: KUMMERMEHR HANS
IPC: D04H1/46
Filed: 1993-01-22
Abstract: In order to be able to consolidate mineral fibers without binder, such as in particular glass wool. into. a needle-felt by needle-punching, an agent as a needling aid which comprises a thixotropizing additive having a relatively low flow viscosity during needling and thus allows to effectively support the needling process; is added to the mineral fibers. At rest. this thixotropizing additive however has an extremely high viscosity, whereby the needle-punched felt obtains good strength. In particular for needling rock wool, suppler textile fibers are moreover added which contribute to improved mutual interlocking of the fibers, in particular in the case of mineral fibers such as basalt fibers, which can only with difficulty be interlocked by needling. A corresponding processing aid furthermore proves advantages in the production of a crimped mat from a laminar mat, as the drastically weakened resistance against further shifting makes it possible to reorient the fibers in the crimping zone, gently and to a large degree, without the application of excessively large forces.

Filed: 1992-12-31
Abstract: Biochemical deactivation of RNA-Viruses with agents R&D as anti-infectives. inventor and applicant: Dr. Urs V. Wirth; Sonnsyterain, CH-6048 Horw, Switzerland. Priority date: 23rd June 1992 applied at BAGE in CH; PCT-application: 31st december 1992 at WIPO         Biochemical Deactivation of RNA-VIRUSES         Abstract:   Ribonucleases (RNases) are highly active, easily used and extremely stable enzymes. Together with detergents, RNases deactivate and destroy irreversibly RNA-viruses. Agents containing RNase(s) and detergents are therefore suitable for disinfecting instruments, clothing and surfaces from contaminating RNA-viruses. Special application forms for coating the skin surfaces of human beings, animals or plants reduce the risk of infection from RNA-viruses. Agents with RNases and detergents. possibly combined with other substances, may be regarded as "anti-infectives against RNA viruses (= aiRVi)".

Title: Method and kit for the determination of antibodies
Inventor: BERGMANN ANDREAS
IPC: G01N33/563
Filed: 1993-12-14
Abstract: For the determination of antibodies (Ak), in particular of autoantibodies, such as human autoantibodies against thyroid peroxidase (hTPO), a procedure is adopted in which the antibodies to be determined are bound to a solid or undissolved phase in a conventional manner using unspecific binders and are then selectively labelled, for a subsequent measurement, by reaction with a crude antigen preparation (Ag) and a further, labelled antibody or antibody fragment (F(AK)*) which are specific for the antigen but are not bound, or not significantly bound, by the binder. The presence of the antibodies (AK) to be determined manifests itself in the form of a label bound to the solid or undissolved phase, the amount of said label being proportional to the amount of the antibodies to be determined in the sample.

Title: Production of boric oxide
Inventor: JACOBS PAUL F
IPC: C01B35/10
Filed: 1994-11-18
Abstract: Amorphous boric oxide - containing product having about 85 to 92% by weight B2O3 is produced by heating boric acid at an elevated temperature of up to about 275°C to dehydrate the boric acid and form a molten glass which is cooled to a solid glassy product. This solid glass can be comminuted to produce a particulate product. Preferably the boric acid is heated at 220° to 275°C, with about 250° to 270°C being most preferred. The process is readily adapted to a continuous process in which the boric acid is placed on a moving continuous steel belt and conveyed through a heating zone. The molten glassy product is cooled to form a solid glassy product which is removed from the belt and comminuted to a desirable particle size range.

Title: Multiple passage cooling circuit for gas turbine fuel injector nozzle
Inventor: MAINS ROBERT T
IPC: F23R3/28
Filed: 1993-09-28
Abstract: A gas turbine fuel nozzle (11) and method of fuel flow provide resistance to coking of the fuel by means of a multiple passage heat transfer cooling circuit. Fuel streams to primary and secondary sprays of pilot (13) and main (15) nozzle tips are arranged to transfer heat between the pilot primary fuel stream and each of the main secondary fuel stream and the pilot secondary fuel stream. This protects the fuel in the streams from coking during both low flow, lower engine heat conditions and high flow, high engine heat conditions. This nozzle and flow can protect engines with both single tip and dual tip nozzles.
