Patent CA-2215023-A1 (CA)
Title: Cleaning device and method
Inventor: SIEGERMAN HOWARD D
IPC: B65D81/32
Filed: 1996-03-08
Abstract: A cleaning kit (101) for use in cleaning surfaces in clean rooms semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers (14) is packaged together with a container (100) of cleaning fluid in a liquid-tight outer container (18). The kit is stored until just before it is to be used. Fluid is released from the inner container (100) into the wipers. In one embodiment, fluid is released from the inner container (100) into the wipers (14), preferably by means of a puncturing device (102) operable to puncture one of the walls of the inner container ( 100) by the application of pressure in a limited area on the outside of the outer container (18). The puncturing device is located away from the edges of the package to minimize the chances of accidental puncture. The cleaning liquid is allowed to soak into the wipers, and the wipers (14) are removed from the outer container (18) for use. The container can be resealed to protect the wipers (14) after the package has been opened.  This device and method minimize deterioration of the wiper material due to prolonged contact with the cleaning fluid, and minimize the loss of effectiveness of substances such as biocides which might deteriorate due to prolonged contact with the wiper material.

Title: Circuit-interrupting device with handling features
Inventor: SCHERER HENRY W
IPC: H01H85/02
Filed: 1997-09-12
Abstract: A circuit-interrupting device for electrical power distribution and transmission systems is provided having improved handling provisions for removal and installation with respect to conventional mountings. The handling provisions permit the circuit-interrupting device to pivot about the lower hinge of the mounting before the circuit-interrupting device is lifted out of the mounting via a handling tool. This permits the dimensions of the circuit-interrupting device to be greater than conventional circuit-interrupting devices. For example, in a preferred embodiment, the circuit-interrupting device includes exhaust diverter structure which directs exhaust away from the mounting, the exhaust diverter structure extending beyond the maximum dimensions which allow the circuit-interrupting device to be directly lifted out of the mounting hinge, i.e. the exhaust diverter structure interferes with the mounting if the circuit-interrupting device is lifted in a direction out of the mounting. The handling provisions include a handling loop on the circuit-interrupting device that is spaced away from the trunnion of the circuit-interrupting device which is received by the lower hinge of the mounting. The location of the handling loop is selected so as to provide suitable pivoting of the circuit-interrupting device before lifting out of the mounting hinge.

Title: Data communications systems and methods using interspersed error detection bits
Inventor: DENT PAUL WILKINSON
IPC: H04L1/00
Filed: 1997-05-01
Abstract: A communication system and method for communicating data bits includes generating error detection bits for interspersing within a sequence of data bits to be transmitted to provide a message to be transmitted. The interspersed data bits may be dependent on the data bits or determined independent of the data bits. The message to be transmitted is convolutionally encoded and transmitted through a communications medium. The received message is convolutionally decoded by a convolutional decoder which is operably connected to an error indication logic circuit. The interspersed error detection bits may be used to detect an uncorrected error in transmission or to constrain the convolutionally decoding to provide an improved error correction operation based on the determinate values of the interspersed error detection bits.

Title: Hardened hydraulic cement, ceramic or coarse concrete aggregate treated with high pressure fluids
Inventor: JONES ROGER H JR
IPC: C04B41/53
Filed: 1997-05-19
Abstract: The properties of cement matrices are improved by one or more of the three processes which can be performed individually, sequentially, or in any desired combination. In each instance a supercritical fluid including at least one substance other than CO2 is flowed through the matrix and the matrix is contacted by the substance to change, e.g. react, constituents of the two with each other. Alternatively, the supercritical fluid can be used as a solvent, itself or by combining it with a solvent which itself may or not be supercritical, and the fluid is infused into the matrix to carry into the matrix and there deposit the dissolved material. This step can be repeated with another supercritical fluid which has a reactant for the material dissolved so that, upon the infusion of the second supercritical fluid, the initially deposited material and the reactant react to provide the matrix with desired characteristics. In a third alternative the supercritical material includes a solvent which itself may or may not be supercritical and which, upon infusion into the matrix passages, dissolves a selected material which can then be flowed out of the matrix.
