IPC: E04G23/02
Filed: 1990-07-18
Abstract: ABSTRACT OF THE DISCLOSURE            A method to remove a depression in a floor extending on top of a supporting underfloor and to prevent recurrence of this depression thereafter, the method comprising: a) determining the pressure that the floor may withstand in use;  b) preloading the floor by exerting onto the depression in the floor a pressure at least equal to the pressure determined in step (a), using,  for example, dead weights to do so; c) injecting an expandable polymeric foam in an unexpanded state beneath the depression in the preloaded floor between this floor and the supporting underfloor and allowing the foam to expand and level the floor until the depression is removed; and d) releasing the pressure exerted onto the floor after the depression is removed.  The pressure exerted onto the floor in step (b) exerts a compressive strength to both the foam injected beneath the floor and the supporting underfloor.  Such a compressive strength in turn causes the foam to reach a density sufficient to withstand any further pressure that could subsequently be exerted onto the floor, while it also ensures that the underfloor is stable enough not to sink.

IPC: F25D3/11
Filed: 1990-09-11
Abstract: A cryogenic freezer apparatus for food products, including a thermally insulated enclosure and conveyor means for conveying products through the enclosure.  A cryogen unit in the enclosure produces cryogen vapor near the enclosure entrance, and a blower unit is located in the enclosure adjacent the entrance thereof.  The blower unit is selectively reconfigurable in response to a blower control signal to selectively direct cryogen vapor in varying directions, drawing cryogen vapor away from a first portion of the enclosure and blowing cryogen vapor toward a second portion of the enclosure.  A photocell unit outside the enclosure, adjacent the entrance thereof, detects cryogen vapor exiting the enclosure entrance and generates at least one sensor output signal in response thereto, being indicative of the amount of cryogen vapor exiting.  A control unit is coupled to the photocell unit and to the blower unit for generating a blower control signal in response to the sensor output signal so that, with increasing vapor detected outside the entrance of the enclosure, the blower unit draws cryogen vapor away from the enclosure entrance.  Also, upon detecting a decreasing amount of cryogen vapor exiting from the entrance of the enclosure, the blower unit directs less cryogen vapor away from the enclosure entrance to assure that intrusion of the ambient environment through the enclosure entrance is prevented.

Patent CA-2035050-A1 (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1991-01-28
Abstract: ABSTRACT      The present invention is an improvement to a method of producing crude argon directly from the cold box of a cryogenic air separation unit.  The improvement is the production of crude argon containing greatly decreased concentrations of oxygen  i.e. <0.5% oxygen  without any loss in recovery.  The improvement is accomplished by using an effective number of theoretical stages in the side arm column so as to produce the desired argon product purity without sacrificing argon recovery; feeding crude liquid oxygen from the bottom of the high pressure column to the reboiler condenser located in the top of the argon side arm column at a rate in the range from about 1.04 to about 1.36 times the theoretical minimum flow of crude liquid oxygen necessary to completely vaporize that minimum flow of crude liquid oxygen to its dew point; and effectuating the intimate contact between the vapor and liquid phases in the argon side arm column by a combination of conventional sieve trays and low pressure drop, structured packings so that the pressure drop across this combination results in a pressure at the top of the argon side arm column such that the flow of crude liquid oxygen to the reboiler/condenser located in the top of the side arm column can be maintained in the appropriate range. Furthermore, the improvement is accomplished without an energy penalty in the cryogenic air separation unit.
