Title: Method and apparatus for transporting powder coating material from a box shaped container
Inventor: MILLER WILLIAM S
IPC: B65G65/23
Filed: 1993-04-07
Abstract: A bulk unloader for emptying powder from an original box shaped shipping container has a support platform with a cradle angularly mounted thereto for holding the container in a tilted position so that one of its corners is lower than the others. A vibrator, attached to the cradle, loosens the powder to facilitate movement of the powder towards the container's lowest corner. A pump connected to the outlet end of a hollow pick-up tube, having an inlet end positioned adjacent the containers lowest corner, draws powder from the container, into the inlet end of the pick-up tube and then transfers the powder to a powder spray gun.      The lower end of the pick-up tube is designed to prevent the plastic bag lining the shipping container from blocking the inlet end of the pick-up tube. A vibration dampening means is provided between the cradle and the support platform to prevent vibrations from being transferred from the cradle to the support platform.

Title: Non-metallic electrical conduit connector
Inventor: SCHNELL KENNETH R
IPC: H02G3/06
Filed: 1993-05-05
Abstract: NON-METALLIC ELECTRICAL CONDUIT CONNECTOR     Abstract of the Disclosure A connector for non-metallic electrical conduit or tubing that  is molded of plastic and is  flexible and resilient and can be used with either plastic or steel electric boxes.  The connector includes a ring, four legs resiliently and pivotally coupled to the ring with adjacent pairs of legs defining a slot therebetween, and four latch tabs located within the slots and flexibly and resiliently coupled to the ring for retaining the conduit within the connector and angled inwardly and extending away from the ring.  Each leg has an arcuate groove therein for locking the connector within an aperture of an electrical box, and the legs form a stop wall for limiting insertion of the conduit within the connector.  Each leg has a transverse arm which spans one of the slots.   As the connector is being inserted into the aperture of the electrical box, each arm slidably engages the next adjacent leg.  Once the connector is fully inserted into the electrical box and conductors have been fed through the conduit,  the arms protect the conductors from being damaged by the electrical box.
Patent CA-2100474-A1 (CA)
Title: Valved catheter
Inventor: LUI CHUN K
IPC: A61M25/00
Filed: 1993-07-14
Abstract: Abstract of the Disclosure A closed-end catheter having a flat-surfaced valve positioned in a recess about the distal portion of the catheter  for  preventing  retrograde   flow  of  blood therethrough  when  positioned  in  a  blood  vessel  of  a patient.  The valve catheter comprises a flexible material, cylindrical tube having a semi-circular cross-sectional wall extending longitudinally about the distal  portion thereof.  The laterally facing valve is formed in a planar surface of a flexible material layer attached to the wall in the distal portion of the cylindrical tube.  One or more passages extend through the cylindrical  tube  in which medicaments or fluids can be simultaneously injected or aspirated.  The valve is formed by inserting one or more flat-surfaced rods in the passages of the tube to stretch the surrounding wall.  A flat-surfaced layer of flexible material  is applied over the flat-surfaced rod to the stretched wall.  The flexible material layer is cured and one or more longitudinally offset apertures are formed therein with the rods remaining in the passages of the tube.  The rods are then removed and a plug inserted into the passages to close the distal end of the catheter.  The stretched wall of the distal portion compresses the fluid apertures to a closed position to prevent fluid leakage therethrough when in a relaxed condition.

Title: Recombinant virus vectors encoding human papillomavirus proteins
Inventor: BOURSNELL MICHAEL E G
IPC: C07C69/65
Filed: 1992-03-10
Abstract: The invention provides a recombinant virus vector for use as an immunotherapeutic or vaccine. The recombinant virus vector comprises at least one pair of nucleotide sequences heterologous to the virus and which have sufficient sequence homology that recombination between them might be expected. The pair of nucleotide sequences are arranged in the virus vector such that they are inverted with respect to each other. The virus vector is able to infect a mammalian host cell and express as polypeptide the heterologous nucleotide sequences in the host cell. For infection thought to be caused by HPV infection, the pair of nucleotide sequences encode part or all of human papillomavirus (HPV) wild-type proteins or mutant proteins immunologically cross-reactive therewith. For an immunotherapeutic or vaccine against cervical cancer, the recombinant virus vector encodes part or all of the HPV wild-type proteins HPV16E7 and HPV18E7 or mutant proteins immunologically cross-reactive therewith.
