Title: Fabrication of creep-resistant specialty alloys reinforced with ferroaluminum shots
Inventor: LHYMN CHANG
IPC: C22C1/02
Filed: 1990-01-15
Abstract: Abstract The fusible alloys or zinc-based alloys are reinforced with ferroaluminum shots to improve the creep resistance of parts used for fire sprinklers, thermal plugs of valves or cylinders, bearings, gears, brackets, fasteners, seals, bushings, rollers, axle housings, cams, guides, lost core plastic molding, inserts, work holding, etc.  Other reinforcible matrix alloys include tin-based, lead-based, copper-based, and aluminum-based alloys used for dynamic and structural parts requiring strength and creep resistance.  Ferroaluminum shots are comprised primarily of iron and aluminum and they are light, relatively nonreactive with zinc, and bondable to afore-mentioned matrix alloys by using inorganic acid-based fluxes of zinc chloride, ammonium chloride, a mixture of chlorides, or a mixture of chlorides and fluorides.          Other fluxes such as organic acid-based chemicals work as a cleaning agent when they can clean surface oxides of both the matrix alloy and reinforcing shots.  Materials for alternative reinforcement include conventional steel or iron shots coated with sodium nitrite, ferroaluminum shots coated with sodium nitrite, nickel, copper, monel, refractory metals, copper or nickel-coated metals, copper or nickel-coated plastics, and copper or nickel-coated ceramics.

Title: Method and instrument for mass analyzing samples with a quistor
Inventor: FRANZEN JOCHEN
IPC: H01J49/42
Filed: 1990-02-16
Abstract: A method for the measurement of mass spectra by three dimensional quadrupole fields (QUISTORs) is presented, in which the ions are mass-to-charge selectively ejected by the effect of a natural sum resonance in an inharmonic QUISTOR. In order to enhance scan speed and mass resolution, the ejection of a single kind of ions can be confined to a very small time interval, either by the generation of ions within a small volume outside the field center, or by an excitation of the secular amplitudes by an additional RF voltage across the end electrodes, shortly before the ions encounter the sum resonance condition in the course of the scan. An instrument for this method is described.

Patent CA-2014823-A1 (CA)
IPC: H05B6/68
Filed: 1990-04-18
Abstract: A heating apparatus such as a microwave oven in which thermal energy of high-temperature vapor generated by heating an object is detected by a pyroelectric element and a resulting detection signal is used to control (stop) a heat source such as a microwave source, etc.  Among AC voltages generated by the pyro-electric element due to heat exchange of the pyroelectric element, a voltage of a polarity generated at the time of heat discharge (temperature decrease) of the pyroelectric element is selectively eliminated through a circuit means.  A voltage generated by heat exchange between air moving slowly in a heating chamber and the pyroelectric element caused by the rotation of a turn-table or the like is eliminated by another circuit means.  A control section controls the operation of the heat source by deciding an output signal of the pyro-electric element by comparing it with a detection level determined in accordance with a noise level for a predetermined length of time after the start of the heating operation.  Erroneous detection is thus prevented which otherwise might be caused by a noise voltage generated in the pyroelectric element by the thermal energy of a hot air staying in the heating chamber after the energization of the heat source or a second heat source.

Patent CA-2020548-A1 (CA)
Title: Skin tanning process
Inventor: SILVESTRE FRANCOISE
IPC: C14C3/06
Filed: 1990-07-05
Abstract: The invention relates to a process for tanning acidified wet raw hides. This process consists (a) in preparing a water-insoluble organic liquid bath, (b) in suspending in this bath an inorganic tanning agent based on a metal compound, especially a chromium salt or complex, (c) in adjusting the degree of hydration of the hides above a minimum threshold of 200% (weight of water added to the dry weight of hides) and below a maximum threshold corresponding to the limit of retention of water in the hide, (d) in bringing the hides thus hydrated into contact in the organic bath containing the tanning agent for a period of at least 4 hours and in slowly introducing a base into the bath so as gradually to raise the pH of the water retained in the hides to a final value of between a minimum threshold of 3.9 in the case of a chrome tanning agent, and a maximum threshold of 4.4 in the case of this chrome agent, and (e) in removing the hides from the bath and leaving them to rest for at least 24 hours. The process of the invention makes it possible to obtain at the same time a complete exhaustion of the tanning bath, an absence of release of tanning agent in the subsequent finishing operations and a leather of good quality.
