Title: Improvements in or relating to adjustable self-locking joints
IPC: A47C1/026
Filed: 1965-01-14
Abstract: 1,149,761. Adjustable seat hinges. ZEALAND ENG. CO. Ltd. and P. N. F. LANGMEAD. 12 April, 1966 [14 Jan., 1965], No. 1757/65. Heading A4J. [Also in Division E2] An adjustable self-locking joint, especially for use between a back-rest and body supporting part of a piece of furniture comprises an arm 10 provided at its end with two spaced friction plates 11 (only one is shown) each having a circumferential row of teeth 12. Disposed between the two plates is a pawl control member 13 and "outside" the plates are two plates 14 (only one is shown) formed on a tubular arm 15 constituting the other part of the joint which pivots about the pin 16 comprising a rivet or belt by means of which the plates 11 are clamped into frictional engagement with the member 13. A pawl 18 is pivotally mounted on the arm 15 and a helical tension spring 21 urges the pawl towards engagement with the teeth 12 on the arm 10. A V-shaped recess 23 in the end 22 and of the pawl control member holds the pawl out of contact with the teeth and a portion of each plate 11 is shaped to provide a cam lobe 25 engageable with the rise of the pawl when the arm 10 is folded close to the arm 15, which lobes swing the pawl against the spring so that the nose of the pawl is brought opposite the recess 23. An arm 26 (for attachment to a leg or leg frame of the chair) is also pivotally mounted at 17 and, adjacent to the pivot, forms two plates 27 (only one is shown) which are disposed on opposite sides of plate 11 and the pawl 18 and are formed with concavely curved edge surfaces 28 which engage with spaced arcuate projections 29 on the plates 11, the arrangement being such that when the back-rest is in an extended position and the arm 10 is in the position shown, the arm 26 is prevented from pivoting but when the arm 10 is folded close to the arm 15 (i.e. when the back-rest is folded flat against the seat), the projections 29 come out of engagement with the surface 28 and the arm 26 is free to pivot (so that the leg portion may be folded flat against the seat parts). As the arm 10 is swung away from the arm 15, the lobes 25 of plates 11 engage the nose of the pawl and urge it against the spring so as to bring the nose into line with the recess 23. Further movement of the arm 10 causes the pawl control member 13 to move slightly in the anti-clockwise direction (by friction with plates 11) so that the recess 23 engages the nose of the pawl and holds it out of engagement with the teeth 12. Slight movement of the arm 10 in the opposite direction locks the joint by virtue of the shoulder 30 of the pawl control member abutting the shoulder 20 on arm 15 and the simultaneous disengagement of the recess 23 and nose of the pawl so that the pawl is forced by the spring into engagement with a tooth 12. Alternative spring arrangements are shown in Figs. 2 and 3 (not shown), the hinge mechanism being substantially identical.

Inventor: GONGWER CALVIN ANDREW
IPC: F16K47/08
Filed: 1960-01-19
Abstract: 901,925. Valves; fluid-pressure servomotorcontrol systems. AEROJET-GENERAL CORPORATION. Jan. 19, 1960, No. 1949/60. Class 135. A liquid flow control valve comprises a housing 10 having an inlet 27 and an outlet 11 connected by a passageway and means, for varying the cross-sectional area of the latter, in the form of a resilient material 26 having passages or interstices therein, and pressure can be applied to the resilient material in order to vary the cross-sectional area of the passages or interstices, thereby controlling the flow of liquid therethrough. As shown in Fig. 1, the resilient material is in the form of rubber balls located between stationary and movable perforated plates 18, 25 so that upon axial movement of the plate 25 via a handle 29, the rubber is compressed and so reduces or completely prevents the flow through the valve; wire-mesh screens 19, may be provided. In a modification, two packs of balls of different degrees of hardness are located in the valve body and separated by a wire mesh screen. In the construction shown in Fig. 2, the resilient material 47 is located in a deformable bag 36 mounted in a housing 35, pressurized fluid being admitted through a pipe 56 to act on the bag and thereby compress the resilient material. The resilient balls may be replaced by a number of rubber tubes located in the valve body and acted upon either axially by manual means or radially by fluid-pressure via a resilient bag as described above; the tubes may be replaced by a block of rubber having a plurality of passageways formed therein. In the further embodiment shown in Fig .3, applied to a float-operated flushing-valve, a movable perforated plate 64 is actuated by the pressure of the controlled liquid acting on a diaphragm 68 connected to the plate, the liquid pressure being varied by a valve 75A. In operation, the liquid pressure acting on the diaphragm compresses the balls and thereby maintains the valve closed until a valve 77 controlled by a float 79 opens and relieves the pressure on the diaphragm via a bleed pipe 76. In place of the rubber balls or tubes a body of sponge rubber may be used.

Title: Improvements in or relating to vortex type separators and to methods of operating the same
IPC: B04C5/15
Filed: 1947-01-23
Abstract: 620,619. Centrifugal separators. VICKERY, F. W. Jan. 23, 1947, No. 2145. [Class 23] [Also in Group XXVI] In a vortex type separator, the undesirable matter which settles in the sump is intermittently, or continuously, cleared by means which prevent ingress of air to the sump so that the amount of matter in the sump remains substantially constant. One means, Fig. 3, for a sump 27 comprises reciprocating pistons 29, 30 which periodically move apart to form a collecting pocket 51. The pocket is moved to the left and washed out by water from a supply under control of a valve 55 opened by contact of a head 53 and the end of the yoke 32. The yoke is moved by pin and slot mechanism 34, 35 through a lever 36, pivoted at 37, which is controlled by a cam wheel 39 and a roller 38. The cam is driven frictionally by a shaft 41, geared to a driving shaft 42, but remains stationary until a cam 48 engages a roller 50 and trips a pawl 46 to release a nose 45. The piston 29, fixed to the yoke 32, is pushed back to the right by the end of the piston 30 which can move relatively to the yoke. The sump 27 is hinged at 59 and held in the position shown by a clamp In a modification the reciprocations of the pistons are obtained through a worm and worm-wheel drive, the wheel having a pin which extends into a slot in the yoke frame. Hydraulic means (Fig. 10) to secure reciprocation are provided by differentsized pistons 69, 70, in cylinders 71, 72 which are controlled by liquid under pressure supplied to or exhausted from pipes 73, 74, 75. The liquid supply is controlled by a rotary valve 110, having part annular channels in its face which co-act with supply or exhaust grooves in the face of a casing 99. A spring 113 presses the valve against the casing. A face cam 117 acts on a head 153 of a valve stem 154 which controls the admission of the flushing water to a pipe 66. The piston 69 is fixed to a rod 68 but lost motion is provided between the rod 68 and the piston 70, the rod having a reduced portion 76, slidable in the piston 70. The pistons contact stops 81, 82. Supply pipes 175 and an exhaust 98, are provided as shown. A further arrangement, Fig. 13, uses meshing screws 83, geared together, which are placed under a static head at their exit, provided by liquid contained in a tank 88, which prevents ingress of air into the separator. A single screw, provided with jets of water along its length, may be used instead. A further means to remove matter from the sump comprises a pocketed wheel which is periodically turned to empty a pocket. A vacuum line is provided on the side of the wheel approaching the sump opening,  or the approaching pocket may be filled with water. A dashpot may be used to control the speed of separation of the pistons 29, 30. The means may be manually operated. Specification 532,808 and U.S.A. Specification 2,375,826 are referred to.
