Title: Improvements in screens
IPC: B07B1/49
Filed: 1965-07-15
Abstract: 1,107,049. Screening apparatus. A. WEHNER. 15 July, 1965 [21 Oct.. 1964], No. 30012/65. Addition to 1,018,713. Heading B2H. [Also in Division B8] The screening surface of the parent Specification is carried by an intermediate frame which is provided with bores for receiving driving pins 4 of one group I of bearer members and formed with longitudinal channelmembers on its underside, the supporting pins 8 of the other group II being arranged to slide in the longitudinal channel-members. The intermediate frame may be made of plastics material and formed in one piece, Fig. 6 (not shown), or in panels, Fig. 1 (not shown). The screening surface (a screen cloth) may be stretched across the intermediate frame or made into individual panels and fitted into the spaces between the channel-members; if desired, the screen cloth may be wave-shaped or stepped. In Fig. 5 (not shown), grooves 5 are provided for the insertion of securing and stretching members for the screen cloth. If desired, the panels may take the form of trays containing rapper balls for cleaning the underside of the screening surface. Both the groups I and II of bearer members may gyrate in the same or opposite direction to give an arcuate forwards and backwards movement to the screen cloth; alternatively the group II may remain stationary while the other group I is gyrated to give an arcuate movement. The pins 4 are arranged to move axially in bushes which are mounted in sleeves 13 and protected from material being screened by members 14. In order to reduce sliding friction during the return motion of the intermediate frame, the surface of the intermediate frame may be provided with friction reducing linings and if desired the ends of the pins 8 provided with ball rollers.

Title: Improvements in and relating to hydraulic governors
Inventor: GREEN GEORGE WILFRID ACLAND
IPC: F02D1/00
Filed: 1947-11-18
Abstract: 638,324. Fluid-pressure servomotor-control systems. BRYCE FUEL INJECTION, Ltd. Nov. 18, 1947, No. 30575. [Class 135] A hydraulic governor of the kind comprising an engine-driven pump in a fluid circulating system, a spring-loaded control plunger subjected to the pump pressure under the influence of a leak-off orifice, and masking means on the plunger for varying the orifice area by manually turning the plunger, is characterized by means for automatically modifying the response of the plunger at each end of the engine speed range so as to increase the percentage run-up at the lower end and decrease it at the higher end, As shown, the pump outlet pressure is applied at the orifice 2 in the wall of the cylinder 1 and the suction at the outlet from the cylinder. A plunger 3, connected to the engine fuel control member and loaded by the spring 12 to move to minimum fuel position, has a masking edge 6 co-operating with the orifice. Rigidly attached to the plunger rod 4 is a ball-ended lever 7 constrained to move in a slot 8 in a manually-operated speed control lever 9, so that movement of the lever 9 rotates the plunger and axial movement of the plunger also produces rotation of the plunger to increase or decrease the orifice area according to whether the rotation produced by the angular setting of the lever 9 is clockwise or anti-clockwise. In the high-speed setting shown, increase in engine speed allows the plunger to move from left to right and the orifice to decrease in area to produce a small run-up. In the intermediate speed setting, the orifice area remains approximately constant for all positions of the plunger. When the lever 9 is turned downwardly for the low speed setting the orifice area increases as the speed increases, thus giving a large run-up. In a modification, a rectangular orifice is inclined to the axis of the cylinder and the masking edges curved in such a way that axial movement alone produces the desired change in orifice area. Specifications 555,630 and 638,325 are referred to.
