Abstract: 624,749. Ironing-presses. PROSPERITY CO., Inc. April 22, 1947, No. 10698. Convention date, July 30, 1941. [Class 138 (ii)] In a pressing machine, for tubular fabric articles of the type with co-operating elements having an opening and closing movement, the element on which the article is sleeved has inclined sides capable of being expanded outwardly by means including a member extending between and operating connections on the sides by endwise movement, the member and connections being housed in the element. An inverted V-shaped steam-heated head 2, Fig. 2, is attached to a swinging arm 7 and is closed on to a stationary buck 1 steam heated by a pipe 16 and moved by means of a piston 29 through links 32, 34 and is opened by springs 36, 37. A frame 12, Fig. 5, of the buck 1 is supported at one end on a table 6 by a bracket 3 and has a prow 13, Fig. 3, at the other end to aid the sleeving of the garment. Attached to the frame 12 by a piano-hinge 11 are hinged sides 10, held into contact with the frame by a spring 27. The sides 10 are suitably padded and are urged apart, to press the garment sleeved over them against the head by means of a rod 22 which is slidably mounted in the frame 12 and which carries a wedge 25, Fig. 7, which engages followers 25 on the sides 10. The rod 22 is operated through a spring- biassed lever 42 by a piston 39. A handoperated cuff clamp 19 is provided and any slack in the garment is taken up by a chain C. The cylinders 28, 38 have a two-hand control mechanism comprising push-buttons 56, 57, one of which closes an exhaust valve 54, the other opening a compressed air supply valve 55. When both push-buttons are depressed, compressed air is supplied to piston 29, which lowers the head on to the buck. In its travel piston 29 uncovers a port 49 enabling the compressed air to operate piston 38 to expand the buck sides 10 and also to operate diaphragms 52, 53, which lock the valves 54, 55. The press is opened by operating either of two release levers 58. This releases air from the diaphragm chambers and allows the valves 54, 55 to return to their initial position because of their springs. Air can then exhaust from the cylinders 28, 38 and the sides 10 contract under the influence of springs 45, 27, and the press opens under the influence of springs 36, 37. The garment is then rotated and the sequence repeated to press the underside.

Title: Improvements in pneumatic transport systems for handling material
IPC: B61D5/00
Filed: 1938-04-08
Abstract: 500,771. Pneumatic conveyers for unloading vehicles and storage chambers. KENNEDY, J. E. April 8, 1938, No. 10789. [Classes 78 (i) and 78 (iv)] [Also in Groups XVII and XXXII] Comprises detailed improvements in the type of apparatus in which pulverized material is loaded into a container at a source of supply, transported in the container to a storage or like place remote therefrom, and then discharged from the container by fluid pressure. Fig. 2 shows containers 12 adapted to be secured to rail trucks by the bars 26 with screwed ends. Each container has a hopper bottom 14, Fig. 4, surrounded by the lower part of the wall 12. A pipe 53, closed by a cap 55 during transport and adapted for connection to a source of fluid pressure, is branched in four directions as follows : (1) a pipe 68 leads to a ring of valved nozzles 66 delivering . in upwardly-diverging directions along the bottom wall of the container; (2) a pipe 64 leading to an upper ring of valved nozzles 62 delivering tangentially along the bottom wall of the container; (3) a pipe 56 leading to an ejector nozzle 58, Fig. 6, fitted in the delivery conduit 47, and (4) a pipe 69 leading througha reducing valve 72 to convey a reduced pressure to the interior of the container above the material. A blow-off valve 73 limits the pressure to which the upper surface of the material can be subjected. The valves in the nozzles 62, 66 are normally closed by springs to prevent ingress of material, but are opened by the pressure of the fluid. The piping and valves are arranged inside the skirt surrounding the hopper, access being provided by a removable door 16. The delivery pipe 47, Fig. 6 is closed during transport by a bolted-down cap with a long stem 52, and a padlock 50 is passed through one of the bolts to prevent tampering. The container is filled through the top by adjusting the valves 33, Fig. 3, axially by rotating the nut 40 carried on the spider arms 38. This construction allows the fluid pressure to close the valve on to its seating 35 independently of the hand gear. A hinged cover 42 is padlocked to prevent tampering during transport. Handles 90, Fig. 2 are fitted to the container for picking up by a crane.

[Also in Division G6] In a nuclear fusion device, the acceleration of ionized particles is effected in a high frequency electromagnetic field, within a resonant structure, in conjunction with both radial and axial magnetic fields. Ionization is produced by cyclotron resonance. Gas is introduced into the cylindrical resonant cavity, 4, Fig. 1, which oscillates in the TE mnp  mode. The target 10 forms one end of the acceleration chamber, 8, and the axial and radial magnetic fields may be either pulsed or continuous. The target is formed of tritium alloyed to titanium. The cavity, 4, may be replaced by a series of separate cavities oscillating at different frequencies. In alternative forms; not shown, plasma is confined between magnetic mirrors and fusion is induced either by beam-beam interaction, using deuterium, or in a thermal reaction. A tritium-titanium target may also be subjected to a multiple beam interaction due to the reflections. The target may fall freely through the plasma in the form of granules. A radial magnetic confining field may be provided by conducting or superconducting rods (62, Fig. 2, not shown).

Title: Improvements in or relating to aircraft jet propulsion apparatus
Inventor: BROWN DAVID MORRIS
IPC: F02K1/56
Filed: 1958-04-03
Abstract: 882,424. Defelcting aircraft propulsion jets. ROLLS-ROYCE Ltd. March 16, 1959 [April 3, 1958], No. 10935/58. Class 4. A vaned structure for jet-propulsion apparatus comprising a jet pipe and nozzle and a duct housing the vaned structure for assisting in imparting to the gas flow a reversed component of velocity, comprises first and second vane means for assisting in imparting to the gas components of velocity in first and second directions respectively, so that the reversed thrust jet issuing from the structure has components ofvelocity at right angles to one another and to the direction of gas flow in to the structure. Fig. 2 is a view of the structure looking radially towards the jet pipe, and Fig. 3 a view seen from the direction of arrow 3 in Fig. 2. The second vane means comprises curved strips 26, 27, supporting cascades of curved vanes 25 constituting the first vane means. Certain strips 27 are relatively rigid, and the vanes on opposite sides of such strips are aligned, e.g. strips 27a and vanes 25a, 25b. On each side of each strip 27 are relatively flexible strips 26, and the vanes on opposite sides of such strips are staggered e.g. strip 26a and vanes 25c, 25d. Thermal expansion of the vanes can thus be taken up by sinusoidal deformation of the flexible strips 26. The outer ends of vanes 25a, 25c, are connected to thin sheet metal walls 28. Two such structures are diametrically oppositely disposed about the jet pipe each in a short duet leading from a port in the jet pipe to an aperture in the nacelle housing the jet propulsion plant. Eyelids in the jet pipe normally blank off the ducts so that the gas flows to the nozzle, but, for reverse thrust, can blank off the nozzle and divert the gas to the ducts and vaned structures, Fig. 1 (not shown). The laterally deflected gas is given a downward as well as a forward component of velocity by the vanes, so that the deflected gases from two side by side engines do not mutually interfere. The vaned structure is supported in the duct in the following way. The relatively rigid strips 27 are provided at their forward ends with flanged portions 30 bolted to facings 31 on the forward wall of the duct, and at their other ends with plug members 33 slidable in sockets 34 on the rear wall of the duct. The walls 28 are provided at their forward ends with bushes 37 aligned with sleeves 38 mounted on the duct walls, and locating members 38a in the sleeves 38 are pivotally and slidably engaged with the bushes 37.

Abstract: 1,005,274. Valves. NEW YORK AIR BRAKE CO. March 16, 1964 [May 17, 1963], No. 10986/64. Heading F2V. A control valve of the sliding plunger type comprises a housing 11 containing a valve bore 19 having exhaust chambers 21, 24, 27, motor chambers 22, 26 and supply chambers 23, 25, a valve plunger 32 slidable in the bore 19 and containing an axial bore 38 intersected by four lateral ports 42, 43, 46, 47, the plunger having a first position in which the ports 42 and 43 register with the chambers 22 and 23, respectively, and the ports 46 and 47 register with the chambers 26 and 27, respectively, a second position in which the ports 42 and 43 register with the chambers 21 and 22, respectively, and the ports 46 and 47 register with the chambers 25 and 26 respectively, and a mid position in which the lateral ports are isolated from the chambers, a reciprocable piston actuator 48 in the plunger bore, flow control check valve units 51, 51<SP>1</SP>, mounted in the bore in abutment with opposite ends of the piston 48, the unit 51 controlling flow between the ports 42a nd 43 and the unit 51<SP>1</SP> controlling flow through the ports 46 and 47, springs 52, 521 biasing the valves 51, 51<SP>1</SP> towards the piston 48, a further port 44 formed in the plunger 32 and opening into the bore 38 in the region of the abutting ends of the unit 51 and piston 48, and another port 45 opening into the bore 38 in the region of the abutting ends of the unit 51<SP>1</SP> and piston 48, the ports 44 and 45 being so positioned that in the first position of the plunger 32 the port 45 registers with the supply chamber 25 and in the second position the port 44 registers with the supply chamber 23. The control valve is used in conjunction with a tilt motor 18 of a lift truck. Fluid from the pump 14 and reservoir 15 is fed past a relief valve 31 to a selected chamber between the end of the piston 48 and a check valve 51 or 51<SP>1</SP> to force both valves axially along the bore 38 against the springs 52 to establish a connection between the selected supply chamber and motor chamber, and motor chamber and exhaust chamber. The exhaust chambers 21 and 27 connect with a manifold 29 and return line to the reservoir 15. The valves 51, 51<SP>1</SP> also function as load drop check valves, since an increase in pressure in either line 16 or 17 is ineffective to open its respective valve 51 or 51<SP>1</SP>, and a decrease in pressure in either line results in a decrease in the chamber between the piston 48 and valve 51 or 51<SP>1</SP>, allowing the spring 52 to move the valve to throttle the flow to exhaust. A further embodiment describes a control valve for the motor of a simple hoist where the load on the motor is uni-directional. This valve has only one check valve unit of the type used in Fig. 1, the piston being restrained from movement in the bore of the plunger in a direction away from the unit by a pin. A spring loaded check valve without ports is used instead of the second flow control check valve.
