Abstract: C A N A D A    S P E C I F I C A T I O N            TO ALL WHOM IT MAY CONCERN:    Be it known that we, Letraset Limited, a British Company, of 195-203 Waterloo Road London SE1 8XJ, England, are in possession of an invention entitled PHOTOSENSITIVE MATERIALS FOR USE IN MAKING DRY TRANSFERS and the following disclosure contains a full description of the invention and of the. best mode known to the inventors for taking advantage of same.          ABSTRACT          PHOTOSENSITIVE MATERIALS FOR USE IN MAKING DRY TRANSFERS      Photosensitive materials for use in the making of dry transfer material are described which comprise two carrier sheets which may be peeled apart and three interlayers.  The central interlayer is an image-forming layer e.g. a pigmented polymer with a photocrosslinkable or photopolymerisable layer on one side and an adhesive layer on the other side.  A dry transfer is obtained by imagewise exposing through a photographic positive and peeling apart the carrier sheets.  Thereafter the material is further irradiated e.g. with UV light, to give a dry transfer material,

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus is disclosed for controll-ing the angle of a pivoted, pendant supported extensible boom and the mast-boom angle between working positions and a transport position.  The structure for controlling the angle includes a wire rope driven by a winch and trained over a boom supporting hoist and over a pendant take-up hoist which includes a floating sheave assembly connected to an extensible portion of the boom by a fixed length pendant.  Another fixed length pendant determines the mast-boom angle when the boom is in working position, and a floating sheave stop is pivoted to the mast in position to cradle and/or abut a portion of the floating sheave assembly for enabling completed control of the mast when moved between its transport position and working positions relative to the boom.

The waistbands are formed by affixing elastic elements between the topsheets and the backsheets (in the waistband region of the diapers) using regularly spaced, transversely extending regions of securement. Regions of nonsecurement are formed between pairs of the regions of securement thereby forming channels which allow the diaper to breathe and also forming corrugations which tend to inhibit waistband rollover.

Abstract: ABSTRACT OF THE DISCLOSURE A flame safeguard sequencer incorporates an interlock checking means that verifies the proper status of the start or preignition interlocks in the burner sys-tem and the run interlocks of the burner system.  In the event that an interlock opens during a period of time when it should not be open, the system can limit the operation of the sequence to a short time period (typi-cally 30 seconds) to allow the interlock to reestablish a normal running state.  If the correct state is reestablished, the system continues normal operation.  If the correct state is not reestablished, the system is shut down on safety and a coded fault-hold indicator advises a serviceman of where to find the problem.

Abstract: ABSTRACT A bandpass filter has a plurality of cascade cavities that operate in a dual-mode and are mounted in a planar relationship to one another.  Each cavity contains a dielectric resonator and resonates at its resonant frequency in two HE11.delta. modes.  An iris is located between adjacent cavities and contains an aperture that can independently control inter-cavity coupling.  The dielectric resonator is cylindrical in shape and an adjustable metallic plunger is located in a wall of each cavity so that the cavity can be tuned over a relatively broad range.  The filter has good mechanical and thermal stability as well as being extremely flexible in the arrangement of cavities.

Abstract: ABSTRACT          Disclosed is an embodiment (60) of an improved vernier control device for selectively moving an object in gross or incremental, vernier amounts of the type comprising a housing (2) fixed against movement with respect to the object to be moved having an open-ended bore (4) extending therethrough having threads (6) disposed on wall (7) of the housing surrounding bore (6).  Bore (6) contains a sleeve (8) that is moveable both axially and rotatably within the housing bore and has one end rotatably connected to the object and a bore (10) therewithin extending from the opposite end.  An operating rod (30) is disposed within and is at least axially moveable within the sleeve bore.  Device 60 is provided with lower friction and improved resistance to thread wear and the ability to withstand increased axial force on the threads as a result of the sleeve having a pair of apertures (35) through opposite walls through which respective thread engagement members (34) are able to be moved radially outwardly into threaded engagement with the threads in response to movement of an intermediate member (36) by movement of the rod axially to a thread engagement position within the sleeve bore so that rotation of the sleeve causes the object to move in vernier amounts and movement of the rod towards the end of the sleeve connected to the object enables members (34) to move radially inwardly through the respective apertures an amount sufficient to cause disengagement with the threads and enables the sleeve to be moved axially within the housing bore and move the object in gross amounts.

Abstract: ABSTRACT OF THE DISCOSURE                  METHOD AND APPARATUS FOR           TRIMMING EXTRUDED STRIP COMPONENTS          A strip component is extruded through a heated roller die apparatus and fed onto a heated anvil roll where a rotatable knife blade is pressed against the sur-face of the anvil roll to trim the strip component.  The anvil roll has a smaller-diameter than the roller die and is rotated so that the surface speed is substantially the same as the surface speed of the roller die.   The anvil roll is heated and is positioned close to the roller die so that the strip component will be trimmed as soon as possible before cooling and the selvage trimmed by the cutter can be conveniently fed back into the roller die apparatus.        The  cutter  may  have  a  rotatable  knife  blade mounted on an arm pivoting about an axis spaced from the surface of the anvil roll for swinging the knife blade into and out of engagement with the strip component on the anvil roll surface.  A weight may be attached to the arm for holding the arm down on a stop member in the operative position of the  cutter.  A number  of knife blades may be adjustably mounted on a knife shaft supported by a pair of pivot arms for cutting the strip component at a number of positions across the anvil roll.  Each of the knife blades is spring mounted to press the cutter discs against the strip component on the surface of the anvil roll.
