Title: Apparatus for introducing bulk materials into pneumatic conveying line
Inventor: HERMAN ALVIN
IPC: B65G53/50
Filed: 1993-05-20
Abstract: ABSTRACT OF THE DISCLOSURE         A portable pneumatic conveyor for various bulk materials  includes  a hopper which supplies  the bulk material to a feed tube.    The feed tube is provided with a feed auger which advances the bulk material along the feed tube and into a chamber through which a current of air is passed by way of air inlet and air outlet lines connected to that chamber.   The bulk material which is deposited within the chamber is fluidized by the air current and carried by the air current through the air line outlet and along the outlet conveying line to a storage site, such as a silo. In order to prevent air blow-back through the feed tube and alongside the auger, the outlet end of the feed tube is provided with a gate which is intended to at least partly close when the flow of bulk material into the chamber slows down or stops.
Patent CA-2097417-A1 (CA)
Title: Method for the determination of sulfidoleukotrienes in tissues and biological fluids and its application in diagnosis of allergies and other inflammatory diseases
Inventor: DE WECK ALAIN L
IPC: G01N33/68
Filed: 1992-09-25
Abstract: The method for detecting the sulfidoleukotrienes sLT of the group LTC4, LTD4 and LTE4 by a single immunoenzymatic ELISA assay is based on the interaction between one or several monoclonal anti-sLT antibodies and an sLT conjugated to a revealing enzyme. A  biological sample, wherein a content of sLT is assumed, is contacted with a monoclonal anti-sLT antibody bound to a carrier. After the sLTs present in the sample are bound to the said antibody, a conjugate of an sLT with a revealing enzyme is added to the charged carrier. Finally the amount of the conjugate bound to the carrier is evaluated, which amount is in an inverse correlation with the sLT bound to the carrier. The method is useful for in vitro-tests for the diagnosis of inflammatory diseases, as rheumatic diseases, immunodeficiencies, allergies or pseudo-allergies. With a priming of the biological samples with cytokines, e.g. with IL3, IL5 or GM-CSF as priming agents, the sensitivity of the method can be increased. The assay is sufficiently sensitive to detect sLT  produced by a few reactive cells in minute volumes of whole blood.

Patent CA-2106834-A1 (CA)
Inventor: BLAHUT DONALD E
IPC: H04N7/173
Filed: 1993-09-23
Abstract: The invention relates to signal distribution systems, such as interactive cable television systems, wherein a central server communicates with remote terminals wherein the server assigns a specific address to each newly-connected terminal for control messages and polls. In the case of an interactive cable television system, such terminal is the set-top box or converter connected between the cable system and the television receiver. Periodically, the server broadcasts a control message containing a tentative address, and polls the tentative address. Upon receiving such a message, a newly-connected converter stores the tentative address and responds to the poll with an uplink message.  After receiving the uplink message, the server inserts the tentative address in its polling list in accordance with the transmission delay measured from sending the poll to receiving the uplink message and selects a new tentative address to use in subsequent broadcast control messages. Uplink messages are echoed by the server and verified by the converter. If the converter cannot verify an echoed uplink message, which can occur if morethan one newly-connected converter responds to the same broadcast control message, the converter repeats its initialization procedure to acquire a new address. After the initialization is complete, system software can be downloaded from theserver to the converter and the converter placed in service.

Filed: 1993-11-24
Abstract: ABSTRACT            Parking brake for motor vehicle with a low application force This brake comprises a lever (1) articulated onto a pin (2), a soleplate (3) and a toggle joint mechanism (8) connected to the application cable (9); this mecha-nism (8) includes a connecting rod which is articulated onto the lever  (1),  the end of the cable  (9)  being connected to the end of the connecting rod (10) through the use of a balance bar (11) which can be moved trans-lationally in a direction parallel to the cable (9). The mechanism  (8)  considerably decreases  the  forces  for applying and releasing the brake. On application, the lever (1) is brought into abutment on the soleplate (3) so that the direction of the force (P) in the connecting rod (10), which force is brought about by tensioning the cable (9), passes above the pin (2), which keeps it in the applied position. A push-rod (16), subjected to a return force (F) and sliding inside the lever (1) auto-matically provides safety locking of the brake in the position for keeping it applied.

Title: Set for the treatment of vascular deformations
Inventor: LERCH KARL-DIETER
IPC: A61B17/064
Filed: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE    In order to destroy vascular deformations in the human body, a clamp is provided which is made from titanium.  The clamp is expanded in the relieved state and is transferable into the clamping position by a clamping ring, which is displaceable along the clamp in the attached state.  The clamp is introduced into the body by a probe, which has a tubular casing and a positioning bar guided therein.  The clamp is transferred into the region of the deformation and applied at the application location as a result of the clamping ring being transferred into the clamping position.  The transfer is caused by a relative movement between tubular casing and positioning bar.  The probe is then released from the positioned clamp.

Title: Positive displacement, variable delivery pumping apparatus
Inventor: NASVYTIS PIUS J
IPC: F04B1/12
Filed: 1994-06-06
Abstract: ABSTRACT OF THE DISCLOSURE   A primary vane pump has a rotor with vanes, and an intermediate casing, which is also rotatable, both mounted in a fixed housing.  The rotor vanes are enclosed in the casing and provide a primary pumping stage.  The rotatable intermediate casing has outer vanes enclosed within the fixed housing, which provide a governor stage vane pump when the casing rotates.  An inlet annulus supplies fuel to passages in the rotatable casing leading to the primary pumping stage and other passages in the rotatable casing conduct pumped fluid out to a discharge annulus.          A closed fluid loop is established from discharge annulus to the governor stage vane pump, out through a valve and back to the discharge annulus.  The reaction on the casing caused by the primary pump rotor tends to rotate the intermediate casing, while pressure drop through the valve in the closed fluid loop resists rotation.  Adjustment of the valve adjusts rotational speed of the intermediate casing and varies the delivery rate of fuel by the primary vane pump.

IPC: B01D61/16
Filed: 1994-09-16
Abstract: The invention provides a process and apparatus for on-site purification of photofinishing effluent produced by mini-lab photofinishing apparatus and the like. The process includes passing the effluent through an adsorbent to adsorb inorganic and organic compounds to produce a primary filtrate fluid. The primary filtrate fluid is directed to a membrane filter which in turn discharges relatively clean permeate fluid which passes through the membrane filter as a secondary filtrate fluid, and rejects concentrate fluid that does not pass through the membrane filter. Preferably the effluent is passed through a plurality of adsorbents of which at least one adsorbent adsorbs inorganic compounds, and at least one other adsorbent adsorbs organic compounds. The adsorbent is provided in containers, each of which has an inlet and outlet provided with conduit coupling means, and conduits interconnect the containers in a series flow path relationship. The container that first receives the effluent becomes exhausted  first, and the container receiving the effluent last is the least exhausted As a container becomes exhausted, a fresh container is substituted and appropriate conduits are connected so that the fresh container becomes the last container.
