Abstract: A B S T R A C T     An auxiliary apparatus for mounting on machines normally used for the spray application of road-markings and which provides the machines with the alternate capability of laying prefabricated road-marking strips.          The auxiliary apparatus is externally mounted on one side of the machine, and it enables layinq of pre-fabricated strips onto the roadway surface without interruption while the machine is moving along, by means of a cutting device and a device which presses the strip firmly onto the roadway surface so as to guarantee freedom from the accumulation of dirt.  The apparatus is adapted for laying a very large quantity of strips, by providing for the substitution of the empty reel by a full one, without any interruption in the laying operation.

Abstract: Abstract In a valve, particularly a thermostatic valve for hot water radiators, an insert for presetting the flow is rotatably mounted in the housing.  A setting element is connected to turn therewith and has formations at its outer portion.  An adjusting ring is axially displaceable relative to the housing from a rest position to an operative position against the force of a spring.  The ring has first coupling zone making coupling engagement with first formations of the setting element in both positions.  There is also a second coupling zone making coupling engagement with second formations only in the rest position.  This provides easy adjustability of the insert and also a secure lock in the set position.

Abstract: ABSTRACT                          UNIT PORTION PACK            A unit portion pack is made from two webs, at least one of which is a laminate  (2) having a layer(4) of tear resistant material, such as polyester film, and a layer (6) of rupturable material, such as aluminium foil.  The two webs (2,26) are bonded together by way of heat seals (38,40) to define a plurality of cavity-forming regions (34) in each of which a single pill (36) or other solid product item is received.  A longitudinally extending score or slit line (10) extends along each longitudinally arranged row of regions (34) inwardly of the peripheries of the regions.  The pill (36) is released by manipulating the pack such that the score or slit line is located on or outboard of the periphery of the pill by movement of the latter.  The area of the cavity-forming region on the other side of the score or slit line to the pill is then squeezed to fracture the rupturable material at the score or slit line.  This forms a dispensing opening through which the pill may be pushed. The design of the pack and the position of the score or slit lines (10) can be chosen such that indiscriminate access to the contents of the package is not possible.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to a waist bag and supporting harness comprising a pelvic belt, a diagonal shoulder strap, shoulder pad means, and underarm strap suitable for attaching to a conventional mail bag or similar bag.  The harness restrains movement of the bag while in use, and inhibits posture deformation of the user.  The harness of the present invention partially redistributes the load of such a bag or device, by providing a pelvic belt to take most of the weight of the bag, and reducing the weight supported by the shoulder strap. As well, the pelvic belt en-hances the stability of a user's centre of gravity by retaining the bag in a substantially constant position relative to the user ' s body while performing mobile duties .       A shoulder pad and strap are restrained by an underarm strap to reduce stress in the neck muscles by preventing the pad and strap from rising up on to the sensitive and vulnerable areas of the lower neck. The bag is provided with a plurality of horizontal belt receiving loops to selectively retain the pelvic belt and position the bag properly relative to the body height of the individual user.

Abstract: ABSTRACT   In an isotope separation system in which hot, isotopically separated vapor is deposited on enriched product and depleted tails plates, deposit adherence is improved and plate cooling simplified. The tails plate is liquid-cooled to a lower temperature which permits the product plate to be radiatively cooled by it simplifying product plate cooling and lowering its temperature to reduce the tendency for the product plate deposit to separate during temperature cycling. In one embodiment plate surfaces are cleaned of impurities in a vacuum by allowing the temperature of the tails plates to reach the relatively low operating tempera-ture prior to proceeding with the deposition. In another embodiment plate surfaces are provided with rough surfaces to promote air penetration during deposit stripping, which permits the formation of a brittle, more easily severed bond between plate and deposit. In a further embodiment for the deposition of biphasic materials, the operating temperature of the tails plate is set to the lowest temperature at which the lower thermal coefficient of expansion phase of the material will adhere to the tails plate.

Abstract: HAND-HELD EMBROIDERY MACHINE  ABSTRACT OF THE DISCLOSURE A hand-held embroidery machine comprises an elongated cylindrical casing sized for grasping in a user's hand and terminating in a truncated cone at the front end.  A hollow embroidery needle protrudes from an opening in the front end of the cone.  The rear end of the needle is received in a needle holder eccentrically mounted on a face gear which is in turn mounted inside the front end of the casing for rotation about an axis normal to the length of the casing.  An electric motor is positioned in the casing rearwardly of the face gear with its output shaft normal to the axis of the face gear.  A pinion gear on the shaft drives the face gear to reciprocate the needle.  Operation of the motor is controlled by a three-position switch actuable by a pushbutton in a side of the casing rearwardly adjacent the cone for selectively driving the needle at different speeds.  The casing has a rear end cap carrying a brack-et for mounting a spool of thread on the casing.  A channel guides thread forwardly from the spool along the outside of the casing to an opening leading into a front compartment housing the needle holder.  Walls inside the compartment converge rearwardly from the eccentrically mounted needle to the opening for guiding a threading wire rearwardly from the needle holder to the channel. The rear end cap is removable to change batteries and the front compartment has a cap which is removable to change needles.
