Title: Transport temperature control system having enhanced low ambient heat capacity
Inventor: DRAKE GILLIAN MICHELE
IPC: F25D29/00
Filed: 1996-02-05
Abstract: In a transport temperature control system having a cooling and heating mode of operation an apparatus and method are provided for enhancing the heating capacity during the heating mode of operation. A second expansion valve is provided to connect the higher pressure liquid line to the refrigerant circuit downstream of the evaporator. When additional refrigerant is needed in the heating circuit to increase heating capacity, especially during low ambient temperature operating conditions, the second expansion valve is caused to open to admit more refrigerant to the system. After passing through the second expansion valve low pressure gas is passed to the compressor, optimizing compressor efficiency such that an increased amount of hot refrigerant gas is delivered to the evaporator for enhanced heating capacity.

Patent CA-2232019-A1 (CA)
Inventor: SALIM KHALID
IPC: E21B33/13
Filed: 1998-03-13
Abstract: The present invention provides methods of stabilizing the portion of an open-hole lateral well bore adjacent to and extending a distance from the junction of the lateral well bore with a primary well bore to prevent erosion and deformation of the lateral well bore during subsequent drilling and other operations.  The methods basically comprise introducing a cement slurry into the portion of the lateral well bore adjacent to and extending a distance from the aforesaid junction under hydraulic pressure whereby the cement slurry enters voids and pore spaces in the walls of the well bore, allowing the cement slurry to set into a hard mass in the lateral well bore and then drilling excess  set  cement  out  of  the  lateral  well  bore.    The stabilization ensures that when a liner is cemented in the lateral well bore, the junction between the liner and the casing in the primary well bore is sealed.
