Title: Method for refuse disposal in solution-mines salt cavities
Inventor: PEARSON ARTHUR G A
IPC: B09B1/00
Filed: 1993-04-20
Abstract: ABSTRACT OF THE DISCLOSURE     A method for Refuse Disposal in Solution-Mined Salt Cavities.  Firstly, form a solution-mined salt cavity having an inlet shaft and an outlet shaft.  Secondly, crush refuse to a particulate size of less than one inch.  Thirdly, compact particulate refuse into sheets less than one inch in thickness at densities in excess of 77 pounds per cubic foot.  Fourthly, break the sheets into cubes less than one inch.  Fifthly, mix the cubes with brine to form a slurry with a minimum volume ratio of 2 portions brine to 1 portion cubes.  Sixthly, inject the slurry through the inlet shaft into a brine filled salt cavity, whereby the cubes, being denser than the brine, settle to the bottom of the salt cavity.

Title: Multiple cartridge syringe
Inventor: HABER TERRY M
IPC: A61M5/19
Filed: 1992-02-20
Abstract: A multiple cartridge syringe (2), especially useful for use in dispensing insulin, includes a body (4) housing first and second pharmaceutical-filled cartridges (30, 32). The cartridges are of the type with a septum (36) at one end (38) and a piston (42, 44) at the other end (40) with the liquid pharmaceutical (46, 48) between the two. The body also defines an accumulator chamber (10) within which an accumulator piston (26) is slidably mounted. The proximal end (12) of the body is open to provide access to the three pistons by a stem (22). When the cartridges are mounted within the body, the septums are pierced by hollow spikes (52, 53) which are connected to a flow path opening into the accumulator chamber. Check valves (58, 59) are used at the distal ends of the spikes to prevent liquid flow back into the cartridges. Pressing on the cartridge pistons forces the liquids into the accumulator chamber. Once the desired amounts of both liquids are in the accumulator chamber, the needle assembly is moved to its extended position which fluidly couples the needle to the accumulator chamber. The injection is given by driving the accumulators piston using the stem.

Abstract: Push-button switches include a housing which defines an interior space and an opposed pair of longitudinally oriented recessed channels.  At least upper regions of the recessed channels are open to said defined interior space.  A pair of elongate fixed contact strips are each positioned within a respective one of the defined recessed channels, the fixed contact strips being of a sufficient length so that a terminal end portion thereof is disposed in the open upper region of the recessed channel to thereby be exposed to the interior space of the housing.  In this regard, the housing preferably includes interior cover walls covering a major extent of the recessed channels so that the terminal end portions of the fixed contact strips positioned therewithin are exposed to the defined housing interior space.          A push-button assembly  is received within the interior space of the housing for reciprocal movements between extended and retracted position,  with a spring urging the push-button assembly into the extended position.  The push button assembly includes a slide contact  member which is movable with the push-button assembly between the extended and retracted positions thereof.  The slide contact member has a pair of resilient contact legs each contacting a respective one of the exposed terminal end portions of the fixed contact strips when the push-button assembly is in the extended position, whereby an electrical circuit is made, and is spaced from the respective one of the fixed contact strips when the push-button assembly is in the retracted position, whereby an electrical circuit is broken.

Inventor: BENTON BARRY W
IPC: G01N27/30
Filed: 1992-10-07
Abstract: ABSTRACT OF THE DISCLOSURE    A pH sensor has an electrode assembly with an electrode with a core of an electrochemically inert insulating or semi-conductive material, and is coated with an electrically conductive, electrochemically sensitive coating.  The preferred core is insulating and made of alumina, with a thin coating of iridium oxide deposited over at least a portion of the outer surface of the core.  The coating is carried to a region remote from the sensing surface and is used for making electrically conductive connections that lead to remote circuitry.  The core is made in a form that can be supported and held in an insulating, electrochemically inert, deformable material that is sealed around the outer surface of the coating on the core to prevent leakage of chemicals being sensed.  An outer housing also permits sealing quite easily into access ports on which the sensor housing is mounted.
Patent CA-2119808-A1 (CA)
Inventor: KNIEPKAMP DAVID I
IPC: G05D23/19
Filed: 1994-03-24
Abstract: In a digital thermostat powered solely by batteries, when the battery voltage drops to a predetermined value, the thermostat effects a visual indication of the existence of a low voltage condition.   If the batteries are not replaced within a predetermined time period thereafter, and the battery voltage remains adequate to operate the thermostat, the temperature  setpoint  is  automatically  altered  by  being lowered, if in the heating mode, or being raised, if in the cooling mode.  The change in room temperature resulting from the change in temperature setpoint should prompt the user to replace  the batteries. By proper manipulation  of  user operable means, the user can subsequently cancel the altered temperature setpoint and re-establish the desired temperature setpoint so as to provide for normal thermostat operation for a predetermined time period during which the batteries can be replaced.

Patent CA-2120984-A1 (CA)
Title: Flowmeter design using self-guided float
Inventor: CHANDRA NIRAJ
IPC: G01F1/24
Filed: 1994-04-11
Abstract: Variable area flowmeters are widely used for measurement of fluid flow for many applications. The essential working part in these devices is a float, moving under the action of fluid flow within a flowtube; the geometry is such that the flow area between the tube and the float varies with float position so that the equlibrium position where flow and gravity forces balance indicates flowrate. The float often uses guide rods for centering the float within the tube so that stable flow readings may be obtained. This invention relates to a novel concept for a self-guided float that eliminates the need for such guides, resulting in a very compact and economical design.

Abstract: METHOD AND APPARATUS FOR EFFICIENT             TRANSFER OF DATA TO MEMORY             ABSTRACT OF THE DISCLOSURE       A method for storing a sequence consisting of a repeated data pattern of three bytes to a memory in double word increments aligned with double word boundaries.  A register is loaded with the first four bytes of the sequence.  The contents of the register are then repeatedly stored to consecutive locations of the memory.  Between each storing of the register's contents, the contents are updated to the next four bytes of the sequence by shifting the second through fourth bytes to the first through third bytes and also moving the second byte to the fourth byte.  When the beginning address where the sequence is to be stored in memory is not aligned with a double word boundary, the initial bytes of the sequence up to the double word boundary are stored and the contents of the register updated to the next four bytes of the sequence.
