Title: Diffusion coating process and method
Inventor: ROSE BERNARD R
IPC: C23C10/02
Filed: 1993-03-17
Abstract: Process for producing novel nickel superalloy bodies having increased resistance of to oxidation and corrosion at high temperatures. The process comprises applying a thin layer of a platinum-group metal and heating to an elevated temperature to diffuse or integrate the platinum-group metal into the surface of the metal superalloy. Then the superalloy body is packed into a container filled with a diffusion powder composition containing sources of aluminum and chromium metals and heated in an inert gas atmosphere to an elevated temperature to codeposit and diffuse aluminum and chromium into the platinum-group metal-treated surface. Finally, the superalloy body is removed from the diffusion coating container and heated to the solvus temperature to form a ductile surface having an outer zone microstructure comprising PtAl2 which has been ductilized by the solutioning of beta chromium. This ductilized PtAl2 may or may not be in a beta phase nickel aluminide matrix depending on substrate composition.

Patent CA-2102092-A1 (CA)
Inventor: GREENSPAN STEVEN L
IPC: H04M3/51
Filed: 1993-10-29
Abstract: A call processing method where a transferring station can be disconnected from a call after the call is transferred to a third station, but where the call is automatically returned to the transferring (e.g. second) station in response to either disconnect signaling or other predefined signaling, e.g., a flash or a dual-tone-multi-frequency (DTMF) tone, without requiring any station to dial the transferring station. The transferring station is for a subscriber to a new, transfer-with-return feature. The feature is invoked for the call either in response to a signal from the transferring station requesting invocation of the feature or because the subscriber has only the transfer-with-return feature and no other transfer feature. The call is also returned in response to a busy or no answer condition of the third station. In an arrangement comprising a switching system connected to the transferring station, and an adjunct switch also connected to the switching system, the initial connection may be from the calling station through the switching system, the adjunct switch, and back through the switching system to the transferring station. After the transfer, the connection need not go through the adjunct switch. <IMAGE>

Abstract: A joint between an upper wall part and a lower wall part of a modular tub/shower unit includes a recessed band adjacent to but spaced from the lowermost edge of the upper wall part. A further band is recessed at the uppermost edge of the lower wall part with the vertical height of that band being greater than the vertical height of the recessed band in the upper wall part and greater than a band at the lowermost edge which is not recessed. The lowermost band of the upper wall part is then adhesively attached to the uppermost edge and a part of the recessed band of the part by a double sided adhesive tape the covering of which is pulled through the gap between these parts. The adhesive tape provides the only sealant necessary for waterproofing the joint and provides the only structural strength necessary. The groove above the lowermost band of the upper wall part allows the upper wall part to be maneuvered into the required position by finger engagement into the groove. The recessed bands adjacent the upper and lower edges of the parts provide stiffening strength.

Title: Diagnosis and monitoring of colon cancer patients by measurement of nca 50/90 in blood
Inventor: ALLARD WILLIAM J
IPC: C12P21/08
Filed: 1994-03-10
Abstract: A method for aiding in the diagnosis of, and monitoring the progression or course of, colon cancer in a patient by measuring the amount of NCA 50/90 in a blood sample, e.g., serum sample, obtained from the patient. Measurement in a single sample of an amount of NCA 50/90 significantly higher than the mean amount of NCA 50/90 in the normal population is an indication of colon cancer in a symptomatic patient. The course of colon cancer can also be monitored by performing a series of specific immunoassays over time to determine changes in the level of NCA 50/90 in blood samples.      Increases in blood NCA 50/90 levels over time are indicative of a deteriorating condition whereas decreasing levels of blood NCA 50/90 over time indicate an improving condition.
