Title: Improvements in annular sealing devices between relatively revolving members
IPC: F16J15/38
Filed: 1954-05-12
Abstract: 749,344. Stuffing-box substitutes. CAMBI IDRAULICI BADALINI SOC. PER AZIONI. May 12, 1954 [March 8, 1954], No. 13847/54. Class 122(5) In a sealing device between two relatively rotating members 8, 9 in which a ring 1 slidably carried by one of the members is pressed axially into sealing contact with the other member 8 by the pressure of the sealed fluid, a packing 3 is movably housed in a recess 10, 11 formed between the ring and its supporting member so that the packing forms a seal at one or the other side of the recess according to the direction of the fluid pressure differential across the sealing device and thereby ensures that the ring 1 is positively pressed against the member 8. The recess 10, 11 communicates through ducts 4 and 5 respectively with the chambers 6 and 7 on opposite sides of the ring 1. If the pressure in chamber 7 exceeds that in chamber 6 the packing 3, in the form of a torus, moves to left and seals the ducts 4 whereas, if the pressure in chamber 6 exceeds that in chamber 7 the packing 3 moves to the right and seals the ducts 5. The area of the ring 1 defined between the circumferences of diameters D<SP>2</SP> and D' is thus always subjected to the higher pressure acting in a direction to press the ring 1 against the member 8. The ducts 4 and 5 may be replaced by providing small clearances between the co-operating cylindrical surfaces of the ring 1 and the member 9.
Patent GB-417839-A (GB)
Title: Improved torque transmission mechanism
IPC: F16H33/08
Filed: 1934-05-08
Abstract: 417,839. Linkwork. ROGER, G., 23, Victoria Road, Macclesfield, Cheshire. May 8, 1934, No. 13853. [Class 80 (iii).] In devices in which driving torque is transmitted from a disc 5 to a shaft 1 on which it is loosely mounted, by means of weighted arms 4 pivoted on a crank pin 3, reverse torques are neutralized by an arrangement of weights 7 pivoted at x to the disc. With the parts in the position shown and the disc rotating as shown by the arrow, the pull of the arm a will assist the motion while that of the arm b will oppose it. On the other hand the out-thrust of the weight c is converted by the pivot x into an in-thrust at the point d and this is conveyed by links e, f, g to the arm b, the pull of which on the pin 3 is thus neutralized. As the weight c moves round, the links e, f diverge and less of the in-thrust is transmitted to the arm b. The four systems of weighted arms 4 and counterweights 7 are interconnected as shown by links h, j, k and bell-cranks l, the shaded pivots being carried by the disc and the unshaded pivots floating. This constitutes a timing mechanism by which the in-thrusts applied to the arms 4 are always nearly proportional to the undesired reverse torques.

Title: Lid-applying apparatus
IPC: B65B43/52
Filed: 1972-03-24
Abstract: 1392932 Lidding apparatus SPOONER FOOD MACHINERY ENG CO LTD 17 Aug 1972 [17 Aug 1971 24 March 1972] 38478/71 and 13974/72 Heading A2A [Also in Division B8] Groups of four baking pans 11 are conveyed, e.g. from a loading station to a baking oven, past a lid-receiving station 12 where each group is supplied with a single lid 13. The advance of the pans is detected by means which operates an actuator (37), Fig 2 (not shown), to release a stop 36 as the front end of the leading pan engages inside the lid and drags it forward. As the stop 36, is returned, it operates a further actuator (33) to release a stop 27 enabling the next lid to slide down on rollers 34 of a conveyor 19 under control of magnets 35. The lids are supplied on freely rotatable rollers 16 of a conveyer 15 and held by a stop 31 coupled to a hydraulic actuator which, in response to a detector, operates to release the stop when a rotor 17 is in position to receive the lid. The rotor 17, which has two sets of rollers 21, 22 and magnets 24, 25, is turned about a spindle 20 by a hydraulic actuator 23; it moves in steps of 180‹, either to and fro or in the same direction of rotation. If four sets of rollers 21, 22 are provided, the rotor 27 may turn in 90‹ steps. A spindle 32 operated by actuator (33) engages the stop 27 to release a lid to the conveyor 19. The rollers 21, 22 and 34 may be positively driven and non-magnetic conveyer bands may overlie the rollers. In a modification, Figs 3-4 (not shown), lids are delivered by a conveyer (55) to a lidturning device (58) formed by a pair of chains carrying pole shoes (63), permanent magnets being provided between each pair of shoes.

Title: Improvements in or relating to the production of artificial silk having a curly and granular appearance
IPC: D01D5/20
Filed: 1937-05-21
Abstract: Artificial silk of curly and granular appearance is obtained by a process in which a spinning solution is forced impulsively through a spinning nozzle with wide nozzle apertures, the impulsive variation of flow through the nozzle having a frequency of 50-250 impulses per minute, and the capillary threads of fluctuating thickness thus produced are stretched by means of a slowly-acting precipitant.  The threads are then subjected to treatment for completion of coagulation and to finishing treatments.  For producing the impulses, there may be provided in the solution-supply pipe at a point near the spinning nozzle, a frictional cock capable of being opened and closed with an appropriate frequency.  In an example cuprammonium cellulose solution is extruded through a nickel spinning nozzle having wide orifices. The supply pipe is provided with a small plug cock which is open and shut from full opening to one-third of the full opening 128 times per minute.  The threads pass through a spinning funnel in which they are stretched by a current of warm, softened water.  The threads are then acidified, freed from copper, and subjected to finishing treatments.

Abstract: 850,124. Controlling aircraft. SHORT BROS. & HARLAND Ltd. May 4, 1959 [May 5, 1958], No. 14370/58. Class 4. [Also in Group XXIX] A hydraulic motor for tilting the jet engines of a vertical take-off aircraft comprises a differential piston 11, Fig. 1, which is slidable in a cylinder 10 and linked to an output member, a main pressure fluid supply 15 connected to each side of the piston, a control valve 17, 18 interposed between the supply and the side of the piston having the greater effective area to couple that side of the piston to the supply or to an exhaust 19, means 28 for connecting an emergency supply 27 to the cylinder, and fluidpressure operated stop means 25 automatically effective where the cylinder is connected to the emergency supply to limit the movement of the piston in one direction from an intermediate position in its stroke. The main supply 15 is connected by a shuttle valve 13 to one end A of the cylinder and by the valve 17 and a pipe 16 to the other end B of the cylinder, the pipe 16 also being connected by the valve 18 to the exhaust 19. Operation of the valves 17, 18 by the pilot connects the end B of the cylinder to the supply or exhaust to tilt the engines to assist acceleration or deceleration during the transition from vertical to forward flight or vice versa. The emergency supply 27 is connected by the valve 28 to the shuttle valve 13 which, depending on which is at the higher pressure, connects the supply 15 or emergency supply 27 to the end A of the cylinder to move the piston to the left. The emergency supply is also connected by the valve 28 to a piston 30 which opens a valve 29 to connect the end B of the cylinder 10 to exhaust 19 and to a cylinder 20, the piston 22 of which moves a rod 23 to the right to radially displace segmented stops 25 in a tube 24 in the cylinder 10 to limit the movement of the piston to the left and tilt the engine rearwardly to a position 5 degrees from the vertical if the aircraft is decelerating. If the aircraft is accelerating with the piston 11 in a position to the left of the stops 25 when the emergency supply is connected to the cylinder, the piston will move to its fully contracted position (the stops 25 not being effective) and the engines positioned to give increased acceleration. In an alternative embodiment, the hollow rod 34, Fig. 3 in the cylinder 10 has a normally closed valve 33 at one end and a normally open valve 35 at the other. When the emergency supply 27 is connected to the cylinder to move the piston 11 to the left, the valve 33 is opened and the shuttle valve 13 is closed to prevent discharge from the cylinder through the normal lines. Liquid in the end B then passes through a transfer port 36 to the interior of the hollow piston rod 12 and closes the valve 35. Further movement of the piston rod to the left closes the transfer port 36 to provide a hydraulic lock which prevents further movement of the piston.
