Abstract: Abstract of the Disclosure A solar collector assembly is capable of directing an extremely thin film of water in direct contact with a collector sheet, the film being formed and regulated by air cushion layers coextensive with the passage or course of water adjacent and in contact with the collector sheet; the pressure of the air cushion layers against the collector sheet and water film is closely regulated both by the pressure of air in the air cushion layers and the relative tension applied to the collector sheet and layers by the outer peripheral connector and frame assembly.  A unique form of connector and frame assembly has been devised to establish both the desired spacing and tension on the sheets while permitting releasable but secure connection of the sheets and layers in place within the frame and simultaneous-ly provide the necessary communication with water and air inlet and outlet channels and headers.

Abstract: COOLING ARRANGEMENT FOR ROTARY KILN          ABSTRACT OF DISCLOSURE         An arrangement for mounting a cooling cowl on the discharge end of a rotary kiln which allows for radial and axial differential expansion between the kiln shell and the cooling cowl.  The cooling cowl is mounted on the kiln contiguous the discharge end of the kiln, with the cowl being positioned radially outwardly of the outer peripheral surface of the kiln to define an annulus between the inner peripheral surface of the cowl and the outer peripheral surface of the kiln through which cooling air can flow to cool the discharge end of the kiln.  A radially outer set of end castings is supported by the kiln shell at the discharge end of the kiln and defines an axial end closure for the cooling annulus between the cowl and the kiln shell.  A radially inner set of end castings is supported by the kiln shell at the discharge end of the kiln and retains the "nose brick" of the kiln lining. Both the radially outer and the radially inner end castings are supported by the kiln in such manner as to be structurally independent of the cowl.  A plurality of spacer bars made of a flexible material such as steel is positioned in the annulus between the cowl and the kiln, the spacer bars extending in a direction substantially parallel to the axis of rotation of the kiln and being angularly spaced apart from each other, the respective spacer bars being fixedly secured at one end thereof only to the cowl and at the opposite end thereof only to the kiln.  As a further feature of the construction, a pair of keeper blocks, preferably supported by the cowl, are positioned contiguous opposite circumferentially spaced sides of a given spacer bar whereby to substantially prevent circumferential shifting of the cowl.

Abstract: ABSTRACT An on/off sprinkler has a body defining an extinguishant inlet and an outlet and is divided internally by a diaphragm defining with the body an intermediate chamber and normally isolating the inlet from the outlet.  The diaphragm has a drain orifice allowing an extinguishant pressure balance on both-sides of the diaphragm.  There is an exhaust port from the intermediate chamber which is normally closed by a valve controlled by a heat sensitive device serving upon attainment of a predetermined temperature value to open the valve thus causing extinguishant exhaustion from the intermediate chamber which results in diaphragm movement to place the inlet in communication with the outlet and sprinkler operation.

When in retracted position, the telescopic mast section is foldable to transport position about a horizontal second pivotal axis which coincides with the axis about which the tower mast section structure folds to transport position.  In a further feature of the construction, means is provided for vertically moving the telescopic mast section and thus for vertically moving the elevating conveyor, including a hydraulic ram assembly which forms part of the telescopic mast section, and in which the hydraulic cylinder element, the piston rod element, and a vertically movable slide member carried by one of said elements are so interrelated with each other and with the stationary tower mast section by interconnecting flexible means such as chains, that operation of the hydraulic ram assembly imparts vertical movement to the telescopic mast section and thus to the elevating conveyor by a "bootstrap" type of operation.

Abstract: ABSTRACT OF THE DISCLOSURE   There is disclosed a new system of pressure sensitive labels mounted along a carrier strip, and means for removing these labels from the carrier strip and applying them to a product.  The label carrier strip is divided down its middle forming separable halves.  The strip carries spaced index marks and labels which are mounted over both halves and positioned uniformly with respect to the index marks.  In some embodiments of the strip and label arrangement, each label has a face carrying a releasable adhesive secured to the carrier and a matrix of the same composition as the labels lies on the carrier strip, surrounding the labels.  With this arrangement, the label-carrying web need not have had its waste (matrix) removed from between and around the labels during manufacture.  An apparatus for transferring such a label from the carri-er strip to an article comprises a bellows support and a bellows with an inner portion mounted on the support.  The bellows is extendable and contractable to move an end face of the bellows away from and towards the support.  Means are provided for supplying a label at the end face of the bellows when the bellows is contracted.  Pressure and vacuum may alternatively be applied to the bellows to contract and expand it, enabling the end face to be thrust toward the article to be labelled.  A check valve may be used to couple the end face of the bellows to its interior, to permit inwards air flow only.

A blocking oscillator produces in the transformer a signal comprising a positive power pulse followed by a negative flyback pulse. The flyback pulse magnitude is modulated by a half-wave diode-capacitor rectifier circuit which supplies negative supply current to an amplifier in the input section.          Other half-wave diode-capacitor rectifier circuits in the input section develop (1) a positive supply voltage for the amplifier, (2) a negative feedback signal for the amplifier, and (3) a level-shifting voltage to be combined with the feed-back signal.  The output section includes additional half-wave diode-capacitor rectifier circuits to develop a demodu-lation signal derived from the flyback pulse, and a bias voltage to be combined with that signal to develop an input signal for the output amplifier.

Further, the support is moved from its initially selected position to the other position during the machine cycle, thereby, in the case of the lasting rolls, varying their position during the machine cycle according to the shoe bottom shape. In the case of the nozzles, on the other hand, once they have engaged the shoe bottom, they are released from any constraint of their widthwise movement and are thus free to follow the shoe bottom edge contour. regardless of the position of the support.
