Abstract: ABSTRACT                    FORCE TRANSDUCER      A force transducer comprises a block of material which is formed with a generally U-shaped or pi-shaped throughaperture and a generally T-shaped throughaperture in such a way as to form two loading members coupled together by first flexure elements which constrain the loading members to move in a predetermined direction under load and a second pair of flexure elements united by a connecting portion.  In use one loading member is connected to a fixture and the other is connected to a force receiver so that when one loading member is displaced relative to the other in said predetermined direction, the second flexure strips undergo a lateral deflection which is a measure of the applied force.  This arrangement is particularly suitable for use with strain gauges as the flexures are subjected to a substantially uniform stress along their lengths when loaded.

Abstract: A B S T R A C T  O F  T H E  D I S C L O S U R E    The remote monitoring system remote locates individually the pairs of intermediate amplification circuits in the transmission line between a monito-ring station and a monitored station. The monitoring station transmits its remote location signals and other control signals which can be mixed with the data signals normally transmitted over the line. The monitoring station analyzes any faults in the signals transmitted and looped in the line and also carries out remote-control of the gain variation of each amplification circuit without normal transmission of the data signals being interrupted. Signals transmitted from by the monitoring station over the forward channel of the line control four loops of the inputs and outputs ofa remote located pair of amplification circuits and a gain regulating means inserted in the negative feedback loop, or inserted upstream or downstream of each amplifi-cation circuit in order to change its gain. The transmission line is of the analog, digital or digital-analog type and is supported by means of a cable, optical fibres, radio links or the like.

Abstract: HEAT-SINK IMAGING METHOD AND APPARATUS FOR LIVE SKIN TISSUE      USING PULSED ENERGY SOURCE                     Abstract of the Disclosure The imaging layer coated side of a heat-responsive recording medium is selectively heat-sinked by the raised portions of live skin tissue contacting the same so that only the unheat-sinked portions of the recording medium will reach an imaging temperature.  The source of heat for the film may be a flash lamp directed against the opposite substrate side of the film where the electromagnetic energy thereof is converted into heat when absorbed by the substrate, or may be a source of externally applied heat transmitted through the substrate to the imaging layer of the film.  In the latter case, the recording medium is preferably initally in spaced relationship with a heat contact plate which is to be contacted by a heat source, which may be the end face of a piston either pre-heated to a given temperature or having a current heatable resistance thereon to be pulsed with current.  In the former case the plunger end face preferably has a low heat conductivity coating thereon.  The live skin tissue, like a finger, is pressed against the imaging layer coated side of the recording medium to bring the substrate side thereof against the heat contact plate which receives heat from the piston end face. The plunger is automatically withdrawn from the heat contact plate a short time after the recording medium is pressed against the heat contact plate to prevent any discomfort or burning of the finger.

Abstract: La présente invention concerne un procédé perfectionné de production de froid et/ou de chaleur selon un cycle à absorption. Ce procédé est caractérisé en ce qu'il comporte au moins deux étapes successives d'absorption d'une vapeur de soluté dans un solvant, au moins une étape de désorption, au moins une étape de condensation de la phase vapeur générée au cours de l'étape de désorption et au moins une étape d'évaporation de la phase liquide obtenue au cours de l'étape de condensation. La première étape d'absorption est réalisée en mettant en contact au moins une partie de la phase vapeur provenant de l'étape d'évaporation avec au moins une partie de la phase liquide provenant de l'étape de désorption, et en utilisant au moins une partie de la chaleur produite au cours de la première étape pour vaporiser partiellement la solution obtenue au terme de la deuxième étape d'absorption. La deuxième étape d'absorption est réalisée dans un domaine de température plus bas que celui de la première étape en mettant en contact une portion résiduelle de phase gazeuse de soluté avec au moins une partie de la solution obtenue au terme de la première étape d'absorption et en cédant la chaleur produite à un fluide extérieur de refroidissement. La solution obtenue au cours de la deuxième étape d'absorption est remontée à une pression plus élevée, permettant toutefois la vaporisation partielle de la solution en prélevant de la chaleur dégagée au cours de la première étape d'absorption, et, étant soumise à cette vaporisation partielle, la solution obtenue au terme des étapes d'absorption et de vaporisation partielle est désorbée, au cours de l'étape de désorption, dans une zone de contact à contre courant dans laquelle la solution est mise en contact avec une phase vapeur engendrée par chauffage de la solution avec apport de chaleur extérieure. La phase solvant résultant de ce contact est recyclée au moins en partie à la première étape d'absorption et la phase vapeur de soluté résultant du même contact est envoyée à l'étape de condensation.

Abstract: Wp-1850 - Coats & Clark, Inc. ABSTRACT           A fastener for use with a hollow wall construction using a conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt.  An end cap within the anchor has an internally threaded head portion and a frangible portion which allows the head portion to separate from the rest of the end cap when the end of the bolt is threaded into the head portion, thus twisting the frangible portion until it breaks.  Thereafter the head portion prevents withdrawal of the toggle bolt from the anchor.  The end of the groove has a threaded portion adjacent the head portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall.          Thereafter, the bolt may be rotated to draw the anchor tightly against the interior of the hollow wall.

Abstract: Abstract of the Disclosure Endblocked methylpolysiloxane fluids, such as trimethylsiloxane-endblocked polydimethylsiloxanes, are made more resistant to thermally induced siloxane rearrangement by incorporating therein titanium-, zirconium-, or hafnium-containing compounds.  Incorporation of these compounds may be accomplished either by mixing organosiloxy derivatives of Ti, Zr, or Hf with the fluid or by mixing certain organic derivatives of Ti, Zr, or Hf with the fluid and heating the mixture to decompose the added organic derivative. Further improvements in the thermal stability of the fluid may be obtained by mixing with the titanium-, zirconium-, or hafnium-containing fluid a small amount of an organosilicon hydride compound.  The thermally stabilized fluids are particularly useful as heat-transfer fluids in non-oxidative, anhydrous environments.

Abstract: SILENCER FOR EXHAUST GASES Abstract of the Disclosure This invention relates to a silencer for muffling the flow of exhaust gases from an engine before they enter the atmosphere.          This silencer comprises a tubular housing having an absorption section with an inlet and an outlet opening.  The absorption section is constructed of three walls: an outside wall, a middle wall and a perforated inside wall.  Positioned between the middle and outside wall is a layer of heat insulating material and positioned between the middle and inside wall is a layer of sound absorption material.  Two symmetrical members are aligned parallel to each other within the absorption section with each member having an inner and an outer wall and a layer of sound absorption material therebetween.  When the two symmetrical members are connected together, they form a hollow tubular inlet connector and a hollow tubular outlet connector which have parallel aligned axis.  In addition, two longitudinally extending slots are con-structed in each tubular connector.  These slots communicate with each other by two separate passageways formed by the perforated inside wall of the absorption section and the outer walls of the two symmetrical members.  These two passageways channel the exhaust gas through the silencer and out to the atmosphere.
