Abstract: Une hormone de concentration de la mélanine (MCH) chez les mammifères a été isolée des tissus de rat, purifiée et caractérisée. Ces peptides de MCH sont utiles pour traiter des troubles de la peau, pour supprimer la prolifération de cellules tumorales de la peau, telles que les mélanomes chez les mammifères, et pour moduler la sécrétion de ACTH. En général, les peptides ont la formule (I), ou sont des homologues naturels des peptides de ladite formule. Les peptides qui sont les homologues naturels de MCH d'espèces mammifères autres que le rat peuvent également être obtenus en utilisant les matières décrites, comme cela est démontré de manière spécifique avec MCH humaine, qui possède la même structure que MCH du rat. Sont également décrites des séquences d'acides aminés et des séquences de nucléotides des ADN complémentaires qui codent les précurseurs putatifs de MCH du rat et de MCH humaine. Ces précuseurs peuvent également comprendre un ou plusieurs peptides biologiquement actifs à terminaison N des MCH matures. Parmi ces peptides, dont on suppose qu'ils se forment à partir des précurseurs de MCH, on trouve les peptides avec la séquence H-Glu-Ile-Gly-Asp-Glu-Glu-Asn-Ser-Ala-Lys-Phe-Pro-Ile-NH2, qui a une réaction croisée avec des anticorps agissant contre alpha-MSH et CRF, et le peptide avec la séquence H-Gly-XNGE-Phe-Pro-Ala-Glu-Asn-GLy-Val-Gln-Asn-Thr-Glu-Ser-Thr-Gln-Glu-OH, dans laquelle XNGE représente Pro-Ala-Val ou Ser-Val-Ala, qui a une réaction croisée avec les anticorps contre GRF.

Abstract: A thermally balanced electronic circuit having an element mounted on a suitable support base, a heat-sink having a bottom portion contacting the element and at least one flange projecting from the bottom portion, and a stress-balancing insert positioned on the bottom portion of the heat-sink and at least partially coextensive with the element, said bottom portion of the heat sink being secured to the element and to the insert by means of an adhesive. The insert is of a material having a coefficient of thermal expansion (TCE), .alpha.1, different from the TCE, .alpha.2, of the heat sink. The TCE of the insert may be intermediate the TCE of the heat sink and the TCE, .alpha.3, of the material of the element. Preferably, the TCE of the insert approximately matches or is equal to the TCE of the material of the element. The element, the bottom portion of the heat-sink, the insert and the adhesive layers form a balanced "sandwich" structure. Such a structure will exhibit planar thermal expansion equivalent to the outer skins of the sandwich structure, e.g. of the element and the insert. Expansion of the structure normal to the element and the insert accommodates the balance of the absolute volumetric change of components of the sandwich structure not accounted for in the skins.

Patent CA-2055251-A1 (CA)
Title: Web tensioning device
Inventor: SHIRLEY GRAHAM L
IPC: B65H77/00
Filed: 1991-11-12
Abstract: Abstract of the Disclosure Web Tensioning a Device A web tensioning device comprises a reservoir (4) into which a loop (26) of the web (24) extends. The reservoir has a width which generally only slightly exceeds that of the web, and a variable pressure drop is established across the loop in the reservoir by means of a fan. Side ports (16;16A) allow a restricted air flow from one side of the loop to the other. The air flow may vary according to the position of the loop. In this way the pressure drop across the loop, and hence the tension in the web, varies with the position of the loop in the reservoir. The device is capable of maintaining a web at a predetermined tension or within a predetermined range of tensions and responds rapidly to external influences on tension, e.g. reversal of drive to the web.

Title: Mold making machine and method of making molds
Inventor: PURMAN FRED V
IPC: B22C21/10
Filed: 1992-03-10
Abstract: MOLD MAKING MACHINE AND METHOD OF MAKING MOLDS                  ABSTRACT OF THE DISCLOSURE          A cope flask is precisely centered relative to a cope pattern by a flask displacement mechanism affixed to a cope stool which linearly shifts the flask relative to the pattern while taking up clearance between the locator pins of the cope flask and the locator bushing in the stool.  This precision centering is maintained while mold sand is pored into the flask and compacted.  The cope mold comprising the flask and the hardened sand is stripped from the stool for subsequent mating with a drag mold made in a similar manner but with the drag stool having locator pins secured in its top surface and the locator bushings provided in the drag flask.  As with the cope mold making procedure, the drag flask is precisely cantered relative to the drag pattern by linearly moving the drag flask to take up clearance between the centering pins and the centering bushing, in the drag with the displacement mechanism.  The flask displacement mechanisms for the cope snd drag are low mass pneumatically actuated units attached to the stools that effectively provides the flask displacement force while allowing bolting and mold sand compacting without adversely affecting mold making machine balance.

Title: Power plant with efficient emission control for obtaining high turbine inlet temperature
Inventor: GOLDBACH GERHARDT O
IPC: B01D53/60
Filed: 1992-03-17
Abstract: ABSTRACT OF THE DISCLSOURE   A power plant with efficient emission control and high turbine inlet temperatures is disclosed. The power plant includes a combustor for the combustion of carbonaceous sulfur-bearing fuel. The combustion of this fuel produces a hot gas with SOx and NOx contaminants. This gas is conveyed to a refractory heat exchanger where some of the heat from the gas is transferred to a pressurized air stream. The gas Is then conveyed to a fluidized bed reactor. The fluidized bed reactor includes a central chamber with a fluidized bed positioned at the base of the chamber. Heat exchangers are positioned within the fluidized bed. These heat exchangers preheat the pressurized air stream which is first conveyedto the refractory heat exchanger and later conveyed to a turbine assembly. The fluidized bed reactor also includes circulating particulate matter, such as CaO.Ammonia may also be injected into the fluidized bed reactor. When operating at a temperature of at least 1,500° F, the fluidized bed reactor facilitates chemical reactions between the CaO and the SOx contaminants. The fluidized bed reactor also facilitates chemical reactions between the ammonia and NOx contaminants. These reactions significantly reduce the contaminants originally found in the hot, dirty gas.

IPC: H03K17/082
Filed: 1992-06-17
Abstract: A protection circuit which electrically isolates logic level and high-side circuits and detects high side power device fault conditions at the isolated, logic level side of the circuit.  When an overvoltage or overcurrent condition occurs at the power switching device, a protection circuit disables the conduction of current through the current carrying terminals of the switching device, preventing damage from occurring to the device.  Activation of the protection circuit effects an increased current flow in the secondary and primary coils of the isolation transformer between the low side and high side elements.  Voltage at the primary coil of the isolation transformer is monitored by low level circuitry to detect the rise in current, indicating a fault to the system controller upon detection.
