Title: Improvements in or relating to appliances for use in applying liquids to surfaces
IPC: A47L1/08
Filed: 1959-04-09
Abstract: 947,190. Liquid-applying devices. P. P. BAGSHAWE. April 6, 1960 [April 9, 1959], No. 11937/59. Heading B2B. An appliance for applying and brushing a liquid on to a surface comprises a liquidapplying roller 10, which may be covered with foamed rubber or plastic, a trailing rotary brush 35 arranged to be frictionally driven by reason of its bristles engaging the surface of the roller 10, and a liquid container 12 disposed above the roller 10 for the gravity supply of liquid thereto, the roller 10, brush 35 and container 12 being attached to one end of a long handle 22, with the roller and brush extending transversely to the handle, in such a manner that as the roller 10 is rolled along the surface to be treated, the brush 35 is resiliently urged into engagement with the surface. The container 12 may be mounted upon a valve body 15 containing a rotary plug-type valve member 26 formed on an extension 27 of the handle 22 which thus controls the flow of liquid to orifices 21 in a pipe 13. Arms 16, 17 are mounted on the ends of the pipe 13, and carry pins 18, 19 on which the roller 10 is pivoted, together with adjustable arms 32, 33 for supporting the roller 35. Springs 38 urge the roller 35 towards the surface to be treated.

Title: A pressing machine for garments and fabrics
IPC: D06F71/02
Filed: 1936-04-27
Abstract: 457,436. Ironing-presses. COLCLOUGH, W., 1836, Elm Avenue, Norwood, Ohio, U.S.A. April 27, 1936, No. 11945. [Class 138 (ii)] The pedal 32 for applying the heavy pressure to an ironing-press is rendered inoperative until after the press head 15 has been lowered manually to safe-closed position. The lower link 19 of the toggles 18, 19 is pivoted to the frame at 22 and is provided with a roller 38 which during the initial closing of. the press rides along the dwell portion 37a of the camshaped end of the pedal 32 which is pivoted at a separate point 33, thereby preventing movement of the pedal. When the press is safely closed the portion 37b of the cam coacts with the roller 38 and completes the movement of the toggle links to straight-line position thereby applying the heavy pressure. The pedal is looked in operative position by a catch 42 carried by a release pedal 40.

Title: An improved helicopter rotor hub
Inventor: ROBERTSON FRANK HENRY
IPC: B64C27/59
Filed: 1953-04-30
Abstract: 734,888. Helicopters. SHORT BROS. & HARLAND, Ltd. April 29, 1954 [April 30, 1953], No. 11959/53. Class 4. A helicopter rotor hub comprises a spider 43 transmitting pitch change to the blades 10, being rockable universally for cyclic pitch change, and movable bodily for collective uniform pitch change, pitch control movements being transmitted to the respective blades through rocking beams 38, the fulcra 39 of which are movable independently of the spider to produce a non- sinusoidal pitch change. The blades 10 are mounted in sleeves 11, and are tied by torsion bars 33 to levers 32 secured to the hub. Each blade root 10 has an arm 35 extending therefrom, connected by link 37 to one end of a rocking beam 38, the other end thereof being linked to one arm 42 of the spider 43. The latter is rotatably mounted on one end of a rod 44 ball jointed at 45 to a tubular member 46 threaded at its lower end 47, so that rotation of drum 48 engaged therewith will move rod 44 axially of the rotor shaft for uniform collective pitch change. Rod 44 may be rocked for cyclic pitch change. The fulcra 39 of beams 38 are carried by levers 40 pivoted in the rotor hub, and bearing with surfaces 51 on cam surfaces 53, 54 formed on one end of a tubular member 56, the other end of which is threaded at 57 and engages a drum 58 rotatable to move axially the cams 53, 54 to rock the levers 40, and effect a collective pitch change. The rotor drive shaft 15 is driven by the planet wheels 18 between a pinion 19 driven from shaft 24, and a fixed ring gear 17. The pilots' controls are shown in Fig. 4, where movement of column 64 fore and aft moves rods 70, 77; 68, 75 and 66, 71 equally and therefore moves the lower end 59 of rod 44 fore and aft: Similarly, lateral rocking o column 64 produces lateral movement of rod 44. Lever 82 operates a cable 78 to rotate drum 48 and vary the collective pitch. A trimming adjustment of collective pitch is provided by rotation of lever 88 to operate drum 58. According to the Provisional Specification the spider may be operated through a swash plate, and the cam surfaces 53, 54 may be of circular cross-section where the cams 51 engage them when the trimming lever 88 is in the datum position, and of oval cross-section elsewhere to give a non- sinusoidal cyclic pitch change.

Patent GB-142820-A (GB)
Title: Improvements in valves for regulating the flow of fluids
IPC: F16K1/12
Filed: 1920-05-03
Abstract: 142,820. Larner, C. W. May 2, 1919, [Convention date]. Valves actuated by fluid under control of auxiliary valve; casings.-Relates to valves comprising a fixed cylindrical guide 2, Figs. 1 and 3, coaxially mounted in the conduit 1 to leave an annular flow passage 3<a>, and a cylindrical valve member 4 sliding therein. The valve member 4 is formed with a valve-seating aperture 6 controlled by an auxiliary valve 7, Fig. 1, or 7<a>, Fig. 3, operated by rack and pinion from a hand-wheel outside the casing, or by an electric motor, or by a piston utilizing fluid pressure from the pipe line. An aperture 18 in the guide 2, smaller than the aperture 6, admits pressure inside the internal bodies 2, 4. This aperture is kept free from obstruction by a prolongation of the rod 8 of the auxiliary valve 7, Fig. 1, or is controlled by a ball valve 19, Fig. 3. When the position of the auxiliary valve 7 or 7<a> is adjusted the valve member 4 moves in the same direction to a position in which the passage 6 is throttled to maintain a balance between the internal and external pressures. The position or opening of the valve 4 is therefore determined by the adjustment of the valve 7 or 7<a>, which controls the operating fluid pressure. The valve 4 may however be actuated by the mechanical arrangement only by the direct abutment of the auxiliary valve on the main valve. The valve shown in Fig. 1 is adapted for the control of fluid flowing from left to right only. Fig. 3 shows a valve for fluid flowing in either direction, the auxiliary valve 7<a> being mounted on the spindle with a lost-motion connexion 9, as shown. When the main valve 4 is closed against pressure from the right hand, the loose auxiliary valve 7<a> is forced open and the ball valve 19 is closed, the interior space being under main pressure. To open the main valve 4, a supplemental valve 22 is opened to relieve the internal pressure through an opening 21 larger than the opening 6. The main valve 4 will then follow up any adjustment of the auxiliary valve 7<a>, the amount of opening being definitely determined by the adjustment of the valve 7<a>. For fluids flowing from left to right the valve 22 is kept closed.

Abstract: Epoxy resins are prepared by reacting in presence of alkali at a temperature between 60 DEG  and 150 DEG  C. a novolac resin prepared from a polyhydric phenol (not including a hydrocarbon or chlorine substituted mononuclear polyhydric phenol) and less than the equivalent amount of an aldehyde and at least 3 mols. of epichlorhydrin per phenolic hydroxyl equivalent of the novolac resin. Many phenols and aldehydes are referred to as suitable for making the novolac resin.  The epichlorhydrin and novolac resin are mixed and alkali metal hydroxide then added continuously or intermittently to effect condensation.  The alkali in amount at least equivalent to the phenolic hydroxyl groups is preferably added gradually as flakes or pellets.  A small quantity of water is useful at the commencement of the reaction.  Examples (1) and (3) describe the preparation epoxy resins from novolac resins prepared from 2,2 - bis - (4 - hydroxyphenyl) - propane and formaldehyde in presence of oxalic acid. Example (5) uses a novolac prepared from resorcinol and formaldehyde in presence of oxalic acid.  Examples (2) and (4) compare glass cloth laminates prepared from resins according to the invention with laminates from conventional epoxy resins.  The products of the invention cure with conventional curing agents some of which are mentioned. They may be mixed with fillers, dyes, pigments, plasticizers, and other resins, e.g. other epoxy resins, phenolic, urea or melamine resins.
