Abstract: A method and apparatus for bonding two tubes in a refrigeration sealed system by soldering. The apparatus includes a pair of jaws which are spring biased in the closed position and a pair of handles for opening the jaws against the spring bias force. The jaws include electrodes having arcuate recesses therein which are arranged in opposed facing aligned relationship so that a pair of tubes may be held between the electrodes. One of the pair of tubers to which the method is applied has a flared end with a larger diameter than the other tube. The ends of the tubes are first cleaned by mechanical means and flux is then applied to the end of the smaller tube. The end of the smaller tube is then slid into the flared end of the other tube in telescoping registry and the telescoped ends are clamped between the electrodes. A solder ring is then positioned around the smaller tube into abutting relationship with the flared end of the other tube.

Abstract: An improved portable apparatus for moving and precisely placing a large and heavy object includes load support rails, aligned pairs of anchoring structures secured to and spaced longitudinally from one another along the rails, an actuator-supporting shoe movable along the support rails having lugs for releasably engaging one pair of the anchoring structures to hold the shoe in a stationary position, and an actuator extending between and connecting the shoe with the load movably supported on the rails. The improvements relate to the configuration of the shoe and to a pair of reinforced spaced anchoring pins which allow engagement with one or the other pin by the lugs on the shoe by merely reversing, or rotating 180.degree., the position of the shoe on the rails. In one position of the shoe with its lugs engaged with one of the pins, retraction of the actuator will produce movement of the load in one direction.

Abstract: Apparatus for monitoring the dielectric composition of articles, particularly articles such as blisterpacks and laminated boards. The apparatus comprises an amplifying circuit including a capacitor between the electrodes (1, 3) of which an article (22) is moved in use. The gain of the amplifying circuit varies with the capacitance of the capacitor so that the amplifying circuit provides an output signal, the peak value of the output signal varying with the dielectric constant of the article (22) between the capacitor electrodes (1, 3). Typically the amplifying circuit includes an operational amplifier (9) the non-inverting input (10) of which is connected to a ground potential (6) and the inverting input (8) is connected to one electrode (3) of the capacitor. A feedback loop (11) is applied between the output (14) of the operational amplifier (9) and the inverting input (8) of the operational amplifier to force the inverting input to the same potential as the non-inverting input.

Abstract: A load control system and tool arrangements are disclosed for controlling the shutheight and back-up load on a mechanical press tool in response to a monitored or measured parameter indicative of press tool force or part quality, which monitored parameter is communicated to a controller for determination of a control signal to control a means for regulating the press tool back-up load and shutheight without interrupting press operations. The control system is operable to control a single station or multi station press and can be installed on either an individual press tool or the bolster or slide. The back-up load is controlled by a non-fluid, moveable mechanical tool back-up mechanism.

Abstract: A fitted bed sheet includes a substantially rectangular main body portion of substantially the same dimensions as a selected mattress. Side portions extend from the sides of the main body portion and terminate in longitudinal edges. End portions extend from the ends of the main body portion and terminate in end edges. Substantially vertical corner seams join the side portions to the adjacent end portions, each seam extending from an inner end at a corner of said main body portion to an outer end at the junction of a longitudinal edge and an end edge. The side edges and end edges are thereby joined together to define a perimeter. There is elastic in at least a portion of the perimeter, to permit the sheet to fit snuggly around a mattress. The present invention is particularly characterized in that the vertical corner seams are at least partly elasticized.
