Granted: 2003-02-11
Abstract: In a vibratory screening apparatus, a withdrawable lower fine mesh screen assembly (17) has a screen unit (19) releasably mounted on a grid/frame structure (20). The screen unit (19) has a sheet (21) of mesh material bonded to a grid or lattice (22) of a yieldable material such as a hard rubber, and this lattice (22) and the edges of the mesh (21) are also fixed to relatively rigid side members (23) which are mutually free each from the others. In the structure (20), a rigid grid of support bars (26) supports the lattice (22) with a sliding contact interface, and a frame (28) incorporates pneumatically actuated tensioners (30) and clamps (34A, 34B) respectively for tensioning/locking the screen unit (19) and coupling the screen assembly to the vibratory structure. The tension in the screen unit (19) is adjustable whilst on the structure (20) by virtue of the yieldability of the lattice (22) and its sliding contact interface with the support bars (26). Away from the screen assembly, the screen unit (19) is relaxed and less vul-nerable to damage or deterioration of tensioning quality.

Title: Method and device for fabricating plastic objects from thermoplastic material
Inventor: ECKARDT HELMUT
IPC: B29C45/17
Filed: 1995-11-15
Granted: 1998-04-14
Abstract: The invention relates to a method for fabricating hollow plastic objects of thermoplastic material, compris-ing the following steps: 1) injecting melt into the tool cavity (1,2); b) Simultaneously and/or subsequently intro-ducing a pressurized fluid into the melt, so that the melt which has been introduced into the molding tool (1, 2) is distributed in the cavity and is pressed against the walls of the molding tool (1, 2), the pressurized fluid being conducted from a pressurized container (5) into the melt, and the pressurized container (5) being supplied with fluid by a compressor (7) which contains a drive element (6); c) allowing the molded part (8) to cool; and d) relieving the cavity of the pressure of the pressurized fluid.  According to the invention, the drive element (6) of the compressor (7) is maintained at a temporally constant power level (P) at least over the production of a large number of plastic objects.  This power level is advantageously calculated from the ratio of the work (W) which must be done by the drive element (6) in order to furnish an amount of pressur-ized fluid that is needed for a certain number of plastic objects over an associated total cycle time (T), relative to this cycle time (T).  As a result, the drive element (6) operates continuously, which results in favorable energy conditions and lower wear.

Abstract: A stereo slide mount is divided into a base frame  (21)  and  a  cover  frame  (22)  in  order  to facilitate  the  operation  for  mounting  the  stereo slide and to improve correctness.  The size of the windows of the base frame is equal to the size of the pictures of the films, and pins (25) are provided at four  corners   of  the  windows   to   engage  with perforations of the film.  The cover frame  (22)  has holes  (26)  that correspond to the pins (25)  and can be fitted to the base frame. The cover frames  (22) are prepared in plural kinds  (#0,  #1, ---)  in which the width  (C1)  between the windows is equal to the width between the windows in the base frame, and the width (W) of the window decreases stepwisely. Plural kinds of masking-amount guide devices (31) having the same size of windows as that of the cover frames and having a collimation pattern at the same position on the  right  and  left  windows,  are  successively  and temporarily fitted to the base frame  (21),  and the image of the stereo slide films is observed using a stereo slide viewer.  The  films are mounted on the base frame by using a cover frame of the same number as the number (#) of the masking-amount guide device (31) with which the sense of distance to the subject in a close-range view is in agreement with the sense of distance to the collimation pattern (35). There is thus obtained a stereo image with the parallax being suitably corrected.

Abstract: A ramp outlet air precleaner has a base assembly, a dome shaped hood, and a rotor assembly. The base assembly includes an inner circumferential wall and an outer circumferential wall, the inner circumferential wall defining an air outlet port. Angled web supports connect the outer circumferential wall to the inner circumferential wall and the arrangement forms air inlet ports that direct air upon the rotor assembly. A ramp extends perpendicularly and axially from the outer circumferential wall and, starting at the top of the outer circumferential wall, the ramp surface winds around the outer circumferential wall in a spiral, terminating near the bottom of the outer circumferential wall below its starting point. The two ends of the ramp form the top and bottom of a particulate discharge port gap. The rotor assembly includes a hub that has arms extending outwardly therefrom. Air drawn into the inlet ports causes rotation of the hub and arms, with the arms flinging particulates outwardly toward the inner surface of the hood where they fall toward the discharge ramp. The spiral shape of the ramp surface creates significant velocity in the particulates, rapidly removing them out of the path of incoming air and discharging them through the discharge port.

Abstract: An improved container for heating grease in a truck including a waste grease holding tank and a heating tank for immersion of a waste grease container into a vat of hot water for loosening the grease in the waste grease container so that the grease in the waste grease container can be dumped into the grease holding tank of the truck. The vat of hot water includes three double walled sides in which an upper edge of the double walls include a plurality of spaced hot water inlet apertures and the bottom of the double wall include fewer smaller drain apertures. The same three sides include hot water flow areas through which hot water flows in order to heat water in the heating tank. The double-walled sides for chambers which receive overflow hot water when a large waste grease container is placed in the vat. These chambers prevent spilling the hot water over the edges of the tank. When the waste grease container is removed the hot water seeks its own level by the water in chambers of the double walls leaking out through the small outlet apertures at the bottom of the double wall. The vat thus recycles hot water for future use in loosening grease in other waste grease containers.
