Abstract: PUMPING SYSTEM                 Abstract of the Disclosure A fluid operated pumping system which includes a main power cylinder divided into a power chamber and a pump chamber by a reciprocally mounted power piston.  An actuator piston is connected to the power piston for synchronous movement there-with and is reciprocably mounted in an actuator cylinder.  A diaphragm type four-way transfer valve is interposed between a power fluid source and the main power cylinder and actuator cylinder, to both of which the valve is connected, and functions to alternately and cyclically charge power fluid at a relatively high pressure to the power cylinder and actuator cylinder, and to concurrently discharge power fluid at a relatively low pres-sure.  The system further includes a needle valve controlled, diaphragm-type, astable pneumatic amplifier which is connected to, and controls the movement of, the transfer valve.  A check valve subassembly is associated with the pump chamber of the main power cylinder for concurrently pumping a secondary fluid at a relatively high discharge pressure.

Abstract: FILTERED ROOF VENTILATOR            ABSTRACT OF THE DISCLOSURE         A roof ventilator is provided with a porous, non-woven, fibrous filter medium having a substantial thickness and selectively installed to prevent the inadvertent infiltra-tion of moisture through the ventilator into the attic space below the roof of a building.  The filter medium is frictionally retained in operative position engaged over openings of such a ventilator by a screen of wire mesh juxtaposed the filter medium.  In operative position, the filter medium presents a high impudence to and will trap or filter moisture from air entering the ventilator from ambient atmosphere and yet, presents a low impedance to and will permit exhausting of air through the ventilator to ambient atmosphere.  The filter medium additionally acts as a barrier against insects so that the screen may have a larger than normal mesh which provides a greater net free open area of the ventilator.

Abstract: AN IMPROVED PROCESS FOR CALCIUM HYPOCHLORITE                  ABSTRACT OF THE DISCLOSURE     A process for producing calcium hypochlorite comprises wetting lime with an aqueous slurry of fine basic calcium hypochlorite crystals in a mixing zone to form an aqueous lime slurry.  The aqueous lime slurry is reacted with a calcium hypochlorite solution in a crystallizing zone to produce a slurry of basic calcium hypochlorite crystals.  The slurry of basic calcium hypochlorite crystals  is separated in a first separation means into a slurry of fine basic calcium hypochlorite crystals and a slurry of coarse basic calcium hypochlorite crystals.  The slurry of fine basic calcium hypochlorite crystals is returned to said mixing zone.  The slurry of coarse basic calcium hypochlorite is conveyed to a second separation means to separate coarse crystals of basic calcium hypochlorite from a calcium hypochlorite mother liquor.  Coarse crystals of basic calcium hypochlorite are admixed with lime and an alkali metal hypochlorite in a third mixing zone to form a mixed alkali slurry.  The mixed alkali slurry is reacted with chlorine to form a paste of calcium hypochlorite dihydrate which is separated into a cake of calcium hypochlorite dihydrate and a paste liquor.  The paste liquor is fed to the crystallizing zone.  The cake of calcium hypochlorite dihydrate is dried to produce granular calcium hypochlorite. The novel process of the present invention produces crystalline basic calcium hypochlorite slurries having high filtration rates.  In addition, the process provides improved crystal growth control and effectively prevents excess nucleation in the crystallization of the basic calcium hypochlorite.

Abstract: ABSTRACT     Apparatus for joining the elements of a thermally insulated composite profile that consists of two metal profiles 24, 25 and at least one insulating rod 47) includes knurled rollers 31, by which the outer channel struts 23, 24 are deformed and pressed onto the insulating rod 47, and provided with a knur-led band. The knurled rollers 31 have bevelled peripheral surfaces 45, 46 pro-vided with serrations, the root between adjacent teeth being parallel to the peripheral surfaces. The knurled roller 31 is mounted so as to be able to slide in the direction of the axis of rotation in a clamp formed by two collars 33, 34. The amount of movement possible from the centre position amounts to 0.5 to 1.0 mm to each side. As a result of this floating mounting of the knur-led rollers, it is possible to compensate for alignment errors between the knur-led roller and the composite profile when the channel struts 23, 25 are being shaped, such errors resulting from an unfavourable accumulation of tolerances in the individual components. The knurled rollers are secured to a driven shaft and advance the joint profile through the apparatus, the joint profile being additionally supported by horizontal and vertical guide rollers 12, 16.

Abstract: ABSTRACT OF THE DISCLOSURE:           A tree harvesting machine is disclosed which is of the type having a wheel-mounted frame, a tree harvesting mechanism at the front and a berth at the rear for accumulated felled trees.  An inverted tree grapple is provided forwardly of the berth and is mounted to the berth so that it can be slid to and from the berth whereby the grapple may be held close to the berth during accumulation of felled trees and moved away from the berth when loaded.  In this last position, the center of gravity of the load has thus been shifted forwardly. The berth itself is pivoted to the frame to allow loading to take place in rearwardly inclined position.  Once loaded, the berth may then be uprighted easily since the center of gravity of the load has shifted forwardly.

Abstract: Abstract of the Disclosure An annulus pressure responsive downhole tool includes a housing having a power piston slidably disposed therein.          First and second pressure conducting passages communicate a well annulus with first and second sides of the power pis-ton.  A retarding device is disposed in the second pressure conducting passage for delaying communication of a suffi-cient portion of an increase in well annulus pressure to the second side of the power piston for a sufficient time to allow a pressure differential across the power piston to move the power piston from a first position to a second position relative to the housing. A pressure relief valve is communicated with the second pressure conducting passage between the power piston and the retarding device for relieving from the second pressure conducting passage a volume of fluid sufficient to permit the power piston to travel to its second position.
