Title: Improvements in or relating to filtration systems
Inventor: FOORD STANLEY GEORGE
IPC: B04B5/00
Filed: 1952-03-12
Abstract: <PICT:0717779/III/1> <PICT:0717779/III/2> Apparatus for growing crystals in a supersaturated solution of the crystallizable material comprises two vessels in circulatory communication with one another through pipes, in one of which vessels the crystal is grown and in the other of which there is mounted a rotary filter with its axis vertical, the filter being so connected to the pipes that the filtrate is delivered from the interior of the filter to the vessel in which the crystal is grown.  The solution in the latter vessel is in a state of supersaturation while in the former (the saturating tank), the concentration is maintained.  Preferably a pump is provided to deliver the filtrate from the saturating tank to the growing vessel.  The filter may comprise a rotatable cylinder 7, Fig. 2, having an outlet 8 and a connection to the atmosphere 9, in a saturating tank 10.  Alternatively it may comprise a cylinder 11, Fig. 3, rotating about a perforate stationary tube 12 having an outlet 14 and atmospheric connection 13.  In each case rotation of the filter sets up a centrifugal force which serves to keep the outer surface free from solids.  Specification 482,096 is referred to.

Title: Improvements in or relating to helicopters
IPC: B64C27/54
Filed: 1948-03-01
Abstract: 639,351. Helicopters. GRAY, H. D. March 1, 1948, Nos. 6404, 6405, and 9680. [Class 4] A contra-rotating rotor system for a helicopter comprises an inner shaft driving a concentric outer shaft, with an upper rotor head mounted on the upper end of the inner shaft and a lower rotor head mounted on the upper end of the outer concentric shaft, each rotor blade being connected to its respective head by link mechanism supported on rotary couplings capable of vertical movement on the shafts to effect simultaneous pitch change of all the blades and in which the lower end of the inner shaft is mounted in bearings in a wheel case carried by a housing supporting a ball member and a universal joint which enables the inclination of the rotor shafts and the rotors to be varied. The rotor drive system is mounted on a hollow ball member B which is free to tilt in a housing A attached to the helicopter structure. Mounted on the ball member B is a turret C and a tube E. An inner rotor driveshaft F is connected through a universal bearing R to a driveshaft Q and carries a bevel wheel G supported in a casing D by a bearing K and engaging through planetary bevel wheels H with a further bevel wheel I fixed to an outer rotor shaft J supported in the housing D by a bearing M. The outer shaft J is supported by a further bearing 0 and in turn carries a still further bearing P to provide an upper support for the inner shaft F. The pitch control arm of each upper rotor blade is connected by a link 12 to a disc 11 rotating with, but free to slide axially on, the inner shaft F and connected to a member 9 held between thrust bearings enclosed in a casing 8 attached to a disc 7 coupled by rods 6 to a further disc 4 with which it revolves in a direction opposite to that of the disc 11. Links 5 connect the pitch control arms of the lower rotor blades with the disc 4 which carries, in a depending cage 3, thrust bearings supporting a collar 2 surrounding but spaced from the outer rotor shaft J. Axial movement of the discs 4 and 7 to effect collective pitch control of the rotor blades is achieved by pivoting a stirrup 1 mounted on the collar 2 to an arm 17 which is connected by rods 14, 15 and 16 and arm 13 to the ends of flexible cables 21, 22 mounted within the ball member B and actuated by a pilot-controlled lever (not shown). Attached to the inner surface of the ball member B are two ball-ended fittings S positioned at 90 degrees to one another in the horizontal plane and to which are connected link rods for effecting tilting of the rotor head in any azimuth. In order that the rotor head may be locked in a selected position the housing A accommodates a split band urged into gripping engagement with the ball member B by springs adjusted by screwed caps 37 and released by a cam actuating lever 39 connected by a cable control to a hand lever on the pilot's control column in such a position that it can be gripped to free the rotor head before the control column is moved. U.S.A. Specification 2,037,745 is referred to.

Patent GB-1566541-A (GB)
Title: Transporting and laying apparatus
IPC: E01C19/52
Filed: 1978-02-17
Abstract: The frame (10) of the device is manually movable on rollers (14, 15); it has a rigid arm (21), the free end of which bears a gripper (30) for gripping stone slabs or the like. The gripper (30) is only movable vertically, in particular by linear displacement of the arm (21) along the vertical T-supports (12) of the frame (10). An energy accumulator (41) accumulates, on the lowering of the loaded gripper (30) which is controlled with the aid of a brake (60), the energy thus released, which guides the empty gripper (30) back into its raised position again. The device is thus permitted a perfect lowering movement during positioning of plate-shaped road surfacings.   <IMAGE>
