Patent CA-1110087-A (CA)
Inventor: CLINE EDWIN L
IPC: G01M15/10
Filed: 1976-07-23

Abstract: ABSTRACT OF THE DISCLOSURE     Modal test method and apparatus is described for use in automotive engine plants, vehicle inspection stations, diagnostic centers, etc., for quickly, accurately and repeatably measuring the principal air contaminants; i.e., carbon monoxide (CO) and hydrocarbons (HC) in engine exhaust gas emissions. Quantative measurement of oxides of nitrogen (NO ) and oxygen (O2) may also be measured if desired.  While O2 is not an air contaminant, a measure of its concentration in the exhaust gas has diagnostic value.  The engines are tested at prescribed modes of operation (usually three; high cruise, low cruise and idle) at which emission-related engine malfunctions, if they exist, are most likely to be exposed.  CO and HC (NOx and O2 if desired) evaluations are made at each test mode and may be recorded on a "report card".  The measured test values of the air contaminants are compared to each test mode with prescribed permissible values either automatically or manually.  For example, the mea-sured values may be recorded on a report card which includes the permissible values.  An excessive value of the measured air contaminants for any prescribed mode indicates an emission-related malfunction and warrants rejection.  Adjust-ment or repair to correct malfunctions is facilitated by providing "truth chart" having a reject pattern matching that on the report card and a written statement of the probable defects and the recommended repair guidelines to enable a mechanic to quickly correct the malfunction. A fixed-fill power absorption device automatically provides a repeatable predetermined engine load at a predetermined test speed for each mode, in accordance with a substantially cube power/speed curve.  An engine evaluation test can be made utilizing the usual three prescribed test modes in conjunction with a fourth mode, namely, engine operation at full throttle.  The latter test may require a power absorption device capable of varying the load on the engine at any speed.  More sophisticated optional equipment provides automatic read-out means for printing measured CO and HC values, with a red print-out for excessive values requiring rejection.

Abstract: U.S. SN 716,313     Filed August 20, 1976 Abstract of the Disclosure A gamma activity counter apparatus for use in automated radioimmunoassay systems including a scintillator counter which has two scintillator crystal-photomultiplier tube assemblies removably contained within a lead radiation shield. Each crystal has formed in it a sample receiving zone, each zone communicating with vertical bores formed in the radiation shield, so that a lifting means can lift sample carriers disposed beneath and in alignment with the sample receiving zones into the zones for gamma activity counting. The lift means is so designed that for each counting period, a pair of sample carriers, separated from each other by an even number of sample carrier spaces, is lifted into the sample receiving zones for simul-taneous counting, the sample carriers being contained in holders that are continually advanced over the lift means in increments of two sample carrier spaces per increment. The sample carriers, arranged in a specified order in the holders, are counted out of order and this counting data is fed to a logic means in which the data is re-ordered, and this properly re-ordered data is fed to a data printing means.

Abstract: IMPROVED SOLVENT RECOVERY IN    A COAL DEASHING PROCESS Abstract of Disclosure An improved coal deashing process wherein coal is mixed with a first dissolving solvent, heated, solubilized and flashed to provide a prepared mixture.  The flashing is effected at a temperature below about 650 degrees F. to increase the amount of the first dissolving solvent in the prepared mixture.  The prepared mixture then is mixed with a second dissolving solvent to produce a feed mixture which is subjected to two or more successive phase separations.  Insoluble coal products present are separated from the feed mixture in a first separation zone and the soluble coal products are recovered from the first and the second dissolving solvents in a  second separation zone.  The second dissolving solvent is recovered from the first and the second heavy fractions and the second light fraction for recycling to aid in producing the feed mixture.  The first dissolving solvent is recovered from the first and second flash zones. This results in an enhanced recovery of the first dissolving solvent for recycle for utilization in the initial solubilization of the coal.

Abstract: ABSTRACT OF THE DISCLOSURE           For preheating a carrier in the form of a wire or fila-ment of hyperpure silicon to a conduction temperature at which an electric current can be passed directly therethrough, a gaseous heat medium such as hydrogen is passed through the interstices of a heated aggregate of hyperpure silicon grains and is thereby both heated and freed from contaminants.  The heat medium is then introduced into contact with the silicon carrier thereby preheat-ing same to the conduction temperature.  The thus preheated car-rier is further heated to a precipitation temperature by direct passage of a current therethrough, and as a gaseous mixture of monosilane or trichlorosilane and hydrogen is the introduced into contact with the heated carrier, pure elementary silicon precipitates and grows thereon.  The granular silicon aggregate can be filled in a vessel of high purity silicon or the like, with a heater provided exteriorly of the vessel for heating the silicon grains therethrough.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to connectors for printed circuits and the like.  In particular, it relates to connectors formed individually by the assembly of blocks of insulating material and contacts which may readily be shortened to eliminate undesired lengths of connector.  The prior art connectors have generally been provided in sizes  to include fixed numbers of contacts.  When there has been a need for more contacts than are in a standard unit, but fewer than in the next larger size, the next larger size has been used with a corresponding waste of contacts and the cluttering of space with unused parts.  The connectors of the present invention are formed from bodies of insulating material such as thermoplastic polyester, having recepta-cles, or cavities, which support pluralities of contacts.  Each contact is positioned in one of the receptacles by engagement of a ridge in the body with a corresonding slot in the contact.  The contacts are locked in their respective receptacles by a slide element which functions cooperatively with a slide receptacle in the contact block.  An assembled connector may be shortened by severing the body to remove portions of the body bearing undesired contacts without disturbing the remaining contacts.  Alternatively, before assembly, the insulating block may be cut to a selected length so that it will accommodate a particular number of contacts and avoid excess contacts.

Abstract: CAPSULE MANUFACTURE                  Abstract of the Disclosure A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material.  The polymerization comprises a reaction between melamine and formaldehyde and/or polycondensation of monomeric methylol melamine or etherified methylol melamine, or a low molecular weight polymer thereof, in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydrocarbon polyelectro-lyte material dissolved in the vehicle.  Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the resulting condensation polymer without further dilution of the manufacturing vehicle.  The negatively-charged polyelectrolyte material is required and has an apparent effect of controlling or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of microcapsules in concentrations of capsule to capsule manufactur-ing vehicle higher than previously possible.
