Abstract: ABSTRACT OF THE DISCLOSURE  A solid state control generates variable interval, high frequency bursts of alternating current to dim or otherwise control a gas discharge lamp or the like, and features an adjustable duty-cycle burst control subcircuit that inter-mittently interrupts a pair of constant, phase-reversed, high frequency pulse sequences, thereby permitting variable interval bursts of the pulse sequences to reach a pair of semiconductor devices.  The semiconductors alternately switch ON and OFF in response to the high frequency pulses applied thereto, thereby rapidly alternating the direction of current flow through a suitable inductor configuration which, in turn, is connected to the load.

Abstract: "ABSTRACT" A temperature-sensitive element on a rotatable drum of a copying machine changes a characteristic in response to a temperature on said drum.  The characteris-tic is employed to control a temperature signal.  The temperature signal from the drum is connected to station-ary portions of the copying machine through sliding con-tacts.  A control circuit responds to the temperature signal to control the energization of a heater to main-tain the temperature of the drum at a predetermined value. The temperature signal and the control circuit comple-ment each other to avoid errors caused by changes in resistance in the sliding contacts.  In one embodiment, the temperature signal is a controlled current, indepen-dent of resistance in series with it, and the control circuit measures the current.  In another embodiment, the temperature signal is a voltage and the control circuit measures the voltage using a circuit whose input impedance is so high that the resistances of the sliding contacts and their consequent voltage drops are negligible by com-parison.  In a third embodiment, the temperature signal is a frequency and the control circuit measures the fre-quency to determine the temperature.

Abstract: ABSTRACT OF THE DISCLOSURE          A collecter for use in a cylindrical shaped chemical process tower wherein it is desired to col-lect and/or redirect the flow of liquid flowing down the tower's internal wall surface, which requires no bolting or welding to the tower and which affords a liquid seal with the tower wall.  The collector comprises flexible annular segments of slightly less radius of curvature than the tower, said segments being in near end to end relationship with each other so as to take the shape of a horizontal seg-mented ring with small gaps between the segments. The flexible segments are spread apart in the tower by spreading means connecting the ends of the adjacent flexible segments until these segments suffi-ciently conform to the tower wall to form both leak-proof seals and friction joints thereinbetween.  Liquid flow along the tower wall in the gaps between the segments is prevented by bridging lips attached to the segments and spanning the gaps while also forming a leak proof seal against the tower wall.

Abstract: Abstract The invention relates to a process for endless-cycle sterilisation of the sheet material utilised in aseptic packaging of pre-sterilised fluid food-stuffs, and to plant therefor. The process involves sterilisation of a continuous sheet of material ?caused subsequently to assume tubular format? by means basically of its being bathed on both sides and then sprayed with superheated steam, this likewise being jetted at either side. Following the heat treatment, the sheet is shaped into a continuous tube and filled, this dual operation coming about within an enclosure maintained in sterile conditions.          An apparatus for carrying the process into effect comprises a first chamber  inside which the bathed sheet  is sprayed with steam, and second chamber inside which sterile conditions obtain, wherein the sheet is duly shaped into a tube  and filled.          The first chamber entry-point is by way of a siphon trap ,  and the first and second chambers are pres-surised to a given level and equalised thus during operation of the plant.

Abstract: Abstract Flow Control Device A flow control device includes metering and pressure regulating elements (70 and 95) disposed one within the other and movable independently of one another for accurate maintenance of a constant pressure drop across the metering valve at a fixed temperature.  Bimetallic elements (145) adjust the position of the pressure regulating element in response to the temperature of the fluid to compensate for variations therein.  The pressure regulating valve element is grounded to the housing (10) of the flow control device in part for ease in adjusting the preload of a spring (130) which balances the pressure regulating element against fluid pressures applied to opposite ends thereof.  The metering element is positionable by the controlled application of servo fluid to a single end thereof.
