Patent CA-1081519-A (CA)
Inventor: JOHNSON BRUCE K
IPC: G03B9/42
Filed: 1977-01-12
Granted: 1980-07-15
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a photographic camera having an automatic shutter latch mechanism which may be released in response to initial shutter blade movement resulting from energization of the shutter drive means and which may thereafter be moved into position to accommodate relatching of the shutter blades in response to film advancement.  The automatic shutter latch mechanism is also responsive to initial shutter blade movement resulting from manually actuated energization of the electrical shutter drive means for actuating a power interlock switch to maintain the electrical energization of a photographic exposure control system after manual deactuation by the user.  In addition, the shutter latch mechanism includes a shock stabilizing arrangement to inhibit the accidental unlatching of the shutter blade mechanism resulting from shutter blade move-ment occassioned through extraneous vibrations, sudden shock or otherwise and not through actuation of the shutter drive means.

Abstract: ABSTRACT OF THE DISCLOSURE           In a tobacco cutting machine where tobacco is cut by knives mounted on a rotating drum, the knives are advanced as they are worn away.  In order to prevent the knives being advanced too far, and becoming damaged by contact with other machine parts, a safety device is pro-vided.  This includes a blade positioned near the path of the knife edges to be struck by a knife if the latter is advanced too far.  The resultant movement of the blade is amplified by a lever system and is used to trigger a microswitch in the cutter drum drive circuit, whereby when a knife is advanced too far the cutter drum is stopped.          The advancing mechanism for the knives includes a ratchet device driven by pulses of compressed air via a piston and cylinder device.

Abstract: TITLE     A METHOD OF RENDERING LIGNIN SEPARABLE FROM CELLULOSE       AND HEMICELLULOSE IN LIGNOCELLULOSIC MATERIAL AND           THE PRODUCT SO PRODUCED                          INVENTOR Edward A. DeLong ABSTRACT OF THE DISCLOSURE         Lignocellulosic material is packed in particulate form in a pressure vessel, steam is passed into the pressure vessel at a pressure of at least 500 psi to bring the ligno-cellulosic material to a temperature in the range 185 to 240°C (preferably in the range 200 to 238°C, more particularly 234°C) in less than 60 seconds (preferably less than 45 seconds) to plasticize the lignocellulosic material.  As soon as the ma-terial is plasticized it is extruded through a die to atmo-sphere where abrasion in the die and explosive decompression forms a particulate material like potting soil that rapidly sinks in water and from which the cellulose content is large-ly utilizeable, e.g. as a feed for ruminants.  During extru-sion the softened material is subjected to severe deformation and then severe mechanical shock thus fracturing the linkages between lignin, the hemicellulose and the cellulose.  The temperature range and rapid rise thereto by the material substantially minimizes degradation of the fragile hemicellu-lose.  The process according to the present invention con-verts lignocellulosic material into a substrate which is extremely easy to treat by enzymes, either as a feed for ruminant animals or for conversion to sugars and alcohols and for the solvent extraction of lignin.

Abstract: ABSTRACT               This invention is directed to a process for preparing a 2-isocyanatoalkyl ester of an unsaturated carboxylic acid by reacting a water-soluble 2-alkenyl--2-oxazoline with a solution of phosgene in a water--immiscible organic solvent in the presence of an aqueous solution of a hydrochloric acid acceptor.  The process is characterized by adding the 2-alkenyl-2-oxazoline into the reaction mixture as an aqueous solution.  The aqueous solution of -the 2-alkenyl-2-oxazoline is prepared by reacting a 2-alkyl-2-oxazoline with formaldehyde to form 2-(.alpha.-hydroxymethylalkyl)-2-oxazoline, dehydrating the 2-(.alpha.-hydroxymethylalkyl)-2-oxazoline to form the 2-alkenyl--2-oxazoline, and separating a volatile composition from the reaction product of the dehydrating step which when condensed, comprises an aqueous solution of the 2-alkenyl--2-oxazoline.  The 2-isocyanatoalkyl esters produced by the process of this invention are useful as reactive inter mediates in preparing coating formulations from hydroxyl--containing compounds that are curable through the carbon--to-carbon double bond.

Abstract: ABSTRACT          A substrate has a pair of spaced apart reflectors forming a resonant cavity capable of supporting an acoustic standing wave at a plurality Or distinct resonant mode frequencies, a pair of terminals, and a transducer connected to said terminals and disposed on a surface of substrate between the pair of reflec-tors. An array Or electrodes which is interdigitally connected in the transducer is symmetrically arranged with respect to A central point or the cavity so as to form a plurality Or pairs of electrodes with the electrodes of each pair being equally spaced in opposite directions from that central point, If the two electrodes of each pair are connected to the same terminal then the transducer has zero net coupling with one set or alternate modes of the cavity whereas if the two electrodes Or each pair are connected opposite terminals then the transducer has zero net coupling with the other set of alternate modes. Thus the transducer can be considered as made up of two equal halves one in each half of cavity. Two transducers in the cavity can have equally suppression of the two quired sot Or alternate modes with the two halves of one transducer of being adjacent in a region between the two halves Or the other transducer. A transducer coupled sur-face acoustic wave coupled resonator electrical filter designed to have a low loss narrow passband may have a low stepband level outside that passband by design of the resonators  such that the combined reflective frequency passband of the resonator reflectors includes only three resonant modes and by a symmetrical arrangement of the transducers with respect to the centres of the resonator cavities so that they couple to only the middle one of those three modes. Fie. 1 is suitable for abridgement.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved floating seal is provided to minimize leakage around the ends of a variable seal turbine stator nozzle for use in cooperation with a circumscribing shroud.      The seal is contoured to float within a pocket formed in the end of the nozzle vane which extends to the vane trailing edge.  The forward end of the seal is forced into engagement with the shroud by the pressure of cooling air from within the vane.  A seal surface attached to the trailing edge of the seal and projecting laterally of the vane utilizes the differential pressure across the vane airfoil surfaces to hold the trailing edge of the seal into engagement with the shroud.  The improved floating seal reduces vane end leakage experienced by prior art floating seals.
