Abstract: ABSTRACT OF THE DISCLOSURE          A process is disclosed for manufacturing cal-cium silicate and/or aluminate based products such as Por-tland cement or aluminous cements. The raw meal is heated to a temperature less than that at which the bothersome impurities such as alkalines, chlorine and sulfur are vola tilized in a preheater-decarbonator 2 and a rotating kiln 3, then the heated raw meal is further heated, in a plasma furnace 1, to a temperature higher than the temperature at which the impurities are volatilized, for example above 1950°C, and more than 80 % of the material is in fusion, in the presence of a reducing gas which subsequently is not brought into contact with the cooling product or only after purification, The process may be used for the manufacture of clinkers of improved quality and/or with lower energy consumption.

Abstract: SKYLIGHT CONSTRUCTION            Abstract of the Disclosure The skylight may be of the domed-type or flat-type and of single or double glass (acrylic or other transparent or translucent plastic) construction.  The skylight fits within an opening in a roof or the like and has a peripheral curb of an extruded rigid thermoplastic, such as polyvinylchloride (PVC), which is fixed to the roof construction about the opening.  The rigid thermoplastic curb has a top co-extruded flexible thermoplastic (such as PVC) gasket integral with the curb and compressible against the edge of the glass or plastic dome or panel.  There is also provided a second flexible in-tegral co-extruded thermoplastic gasket adapted to contact a retainer secured to the curb for retaining the dome or panel on the curb.  The rigid curb is of a thermoplastic in the shore "D" durometer hardness scale, while the flexible gaskets are of a thermoplastic in   the shore "A" durometer hardness scale.  A heat platten welding technique, which would most commonly be used in welding the curb frame mitres, would also weld the gaskets simultaneously for a continuous seal.  Other less commonly used thermoplastic welding techniques, such as ultrasonic, hot gas, high frequency and friction, could be employed to accomplish the simultaneous bond at the corners.

Abstract: ABSTRACT OF THE DISCLOSURE            A fastener applying tool driven by air in a driving stroke and a return stroke featuring noise and recoil reduction and increased efficiency, driving force, and speed of operation.  Air directed into the main cylinder to force the main piston through its driving stroke is stored in a chamber to rapidly return the main piston.  Air compressed by the main piston at one end of the main cylinder is used to form an air cushion to keep the main piston from striking the bottom of the cylinder.  The main piston cycles within a slidably mounted main cylinder.  Pressurization of one end of the main cylinder during the driving stroke repositions the main cylinder to close the main valve to shut off high pressure air from the main piston and open a valve to vent the air above the piston to atmosphere.  Upward movement of the cylinder and rapid return of the piston significantly reduces the recoil force normally experienced in such a tool.  A valve assembly coaxially located at the opposite end of the main cylinder functions to admit and exhaust air to pressurize and vents the piston and main cylinder respectively.  Noise suppression is achieved by an elastomeric cap.  Rapid acting components reduce air wastage and improve overall tool efficiency.

Abstract: ABSTRACT     Apparatus for circular surgical stapling of hollow organs comprising an instrument and disposable cartridge. The instrument comprises a housing with a throughbore in which a tube is received for reciprocation by means of a manually operable squeeze handle.  A rod reciprocates within the tube by means of a wing nut cooperating with a threaded part of the rod.  A two-part disposable cartridge assembly comprised of an anvil carrying part and a staple carrying part are detachably mounted on the rod and housing, respectively.  A key is provided to hold the housing and rod in rotational orientation.  Mutually coacting stops on the tube and rod determine the extent of reciprocation which is variable in dependence upon the position of the rod which in turn is dependent upon the juxtaposition of the anvil carrying part with the staple carrying part when the apparatus is closed on issue preparatory to effecting a circular anastomoses.

Abstract: ABSTRACT            Treating Liquids in Tanks Liquid is caused to circulate in a shallow tank which has an operational depth less than half the effective maximum distance across the tank.  One wall 17 defines with another wall a corner 18 and a bubble curtain 19 is provided along the wall 17 adjacent the corner 18 which imparts to the liquid in the tank an upward vertical  component of movement which is asymmetrical along the wall 17, causing greater vertical movement of liquid at said corner than at the other end of the wall.  Liquid rising up the wall 17 moving away therefrom by reaction therewith will circulate with a hori-zontal component due to the asymmetrical arrangement of the bubble curtain.  The invention can be applied to the sep-aration of materials of different densities e.g. the sep-aration of suspended solids or emulsified oils from waste water.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.
