Title: Improvements in or relating to reels for winding and delivering thread or the like
IPC: B65H49/30
Filed: 1937-04-27
Abstract: A reel for winding and delivering thread or the like particularly for use during the liquid processing thereof, is supported at one end, has no shaft extension beyond its face at the other end, and comprises two sets of longitudinally extending bar members, at least one set being adapted to advance the material wound around the reel by reciprocatory lengthwise movement of the bar members thereof, this lengthwise movement of the bar members advancing the material from the supported end to the unsupported end of the reel.  As shown, the reel comprises two sets of interengaging bars 3, 4 carried by a member 6 and members 15, 16 respectively.  The member 6 carrying the bars 3 forms a rigid cage fixed to the rotatable <PICT:0496385/IV/1> shaft 12 and the members 15, 16 are connected by swivel joints with the bars 4 and are rotatably mounted on a frame member 11 within which the shaft 12 is eccentrically journalled; the members 15, 16 are also inclined to the axis of the shaft 12 so that as the reel is rotated, the bars 4 move in and out between the bars 3 and longitudinally relative thereto, the material wound on the reel being thus transferred from one set of bar members to the other and the succession of turns of yarn being advanced bodily lengthwise of the reel towards the free unsupported end thereof. The swivel joints connecting the bars 4 to the members 14, 15 comprise headed pins 23 mounted in sleeves 25 screwed into the members and having flattened parts pivoted by pins 24 in slots 22 in the members.  The members 14, 15 may be directly mounted on inclined parts of the frame member 11 or on a sleeve fixed thereto.  The members 14, 15 may be connected together and to the members 6, 8 by bellows 29, 30, 31 to prevent access of processing liquid to the interior portions of the reel. Specification 378,467 is referred to.  Reference has been directed by the Comptroller to Specifications 474,973, 474,974, and 475,024.

Title: Hydraulic valve
IPC: F15B13/02
Filed: 1964-03-23
Abstract: 1,000,500. Valves. NEW YORK AIR BRAKE CO. March 23, 1964 [June 20, 1963], No. 12133/64. Heading F2V. A valve comprises a housing 11 containing a bore 14 intersected by three spaced chambers, a supply chamber 19, exhaust chamber 22 and an intermediate motor chamber 21, a valve member 26 movable in the bore 14 containing an internal passage 34 intersected by ports 39 and 41, the valve 26 having a first position in which the port 41 registers with the motor chamber 21, a second position in which the port 39 registers with the supply chamber 19 and the port 41 with the motor chamber 21, and a third position in which the port 39 registers with the motor chamber 21 and the port 41 with exhaust chamber 22, a check valve seat 42 encircling the internal passage and located between the ports 39 and 41, a check valve head 43 reciprocable in the passage 34 and co-operating with the seat 42 for controlling flow from the port 39 to the port 41, reaction surfaces on the head 43 subject to the pressure in the port 41, i.e. the annular area defined by the difference in diameter of the seat 42 and the outside diameter of the head 43, and the end wall area of the bore 47, for developing forces that urge the head 43 in both directions, the surfaces being so proportioned that the force urging the head in the opening direction does not exceed the force urging the head in the closing direction, means, e.g. a sleeve 45, defining a vent chamber within the valve member 26 which communicates with the exhaust chamber 22 at least when the valve member is in the first position, a relief passage 49 connecting the vent chamber with the port 41, and a relief valve 51 normally preventing flow from the port 41 to the vent chamber through the passage 49 but arranged to open that passage upon occurrence of a predetermined pressure in the port 41. The valve member 26 further comprises a bore 33 having a seat 42, the valve 43 not being provided, and ports 37 and 38 which can be operatively connected with further exhaust, motor and supply chambers 15, 16, 17, respectively, in the control of a double-acting piston motor 59. In the first position of the valve, shown in the drawing, the pump 55 delivers fluid from the reservoir 56 past a relief valve 25 and through the grooves 27 and 28 to the exhaust 13 and reservoir 56. Excessive load pressure in the line 58 and chamber 21 is relieved by valve 51. Rightward movement of valve 26 allows fluid to be delivered to the motor 59 through chamber 17, ports 38, 37 and chamber 16. Exhaust fluid in the chamber 21 acts on valve 43, against the action of spring 54, to pass to exhaust chamber 22. Leftward movement of valve 26 allows fluid to be delivered to motor 59 past valve 43 by overcoming the combined pressure of spring 54 and the load pressure in chamber 21 and to be exhausted through chamber 16, ports 37 and 38, and chamber 17. Specification 892,036 is referred to.

Title: Improvements in or relating to Reproducing Apparatus for use with Phonographs and other Talking Machines.
IPC: H04R11/08
Filed: 1919-05-14
Abstract: 126,970. Soc. Anon. des Etablissements Gaumont. May 17, 1918, [Convention date]. Magnetic instruments. - An electro-magnetic reproducer for phonographs &c. comprises a magnetic blade connected to the stylus arm and vibrating between the poles of a magnet, the blade being surrounded by a coil connected to a telephone receiver preferably through a relay. The stylus arm 3 is horizontally pivoted to a vertical post 14 turning in a socket 15. The magnetic blade 1 is secured in a vertical position to the arm 3 preferably at a point three-quarters of the length of the arm away from the stylus 10. The upper end of the blade 1 is secured to an iron block 4 attached to the magnet 5 by screws 6, which are adjusted so that the magnet poles N, S are equidistant from the blade. A coil 9 surrounds the blade 1, and a frame 7 of non- magnetic material is clamped to the magnet by a screw 8, which also permits adjustment of the distance between the poles. When the blade 1 is in a central position, the magnet flux does not pass along the blade, but when the blade is vibrated to either side the flux is diverted along the blade, producing electromotive forces in the coil, 9, and causing the telephone receiver to emit sounds corresponding to the sounds recorded. Although the magnet 5 and frame 8 are supported on the arm 3, their inertia prevents them from following the vibrations of the arm. The natural period of oscillation of the magnet and frame mounted on the elastic blade should be greater than the period of the sounds to be reproduced.

Title: Method and apparatus for coating liquid compositions onto webs of paper and other material
Inventor: GEEST WILFRIED FLORENT DE
IPC: B29C48/05
Filed: 1964-03-23
Abstract: 1,072,951. Web coating apparatus. GEVAERT PHOTO-PRODUCTEN N.V. March 23, 1964, No. 12211/64. Heading D1L. A method of coating a liquid composition on to one side of a web comprises advancing the web and causing the liquid to flow as a continuous film on to the web from a slot like orifice located adjacent the web surface, the flow being achieved or assisted by maintaining an electrostatic field between the liquid composition supplied to the orifice and an electrically conductive member or part which is close to or in contact with the other side of the web. The apparatus shown in Fig. 1 comprises a backing roller 13 to which web 11 is fed, coating head 17 communicating with tray 18 for coating composition and electrical supply 14. Roller 13 is insulated by journalling its shaft in insulated bearings and means are provided for connecting said shaft to the potential source 14. The potential difference between the backing roller and the emulsion supply creates an electrostatic field which traverses the web and the air gap between the web and the coating head and establishes an emulsion meniscus between the web and the coating head. The backing roller may be slightly less in width than the web so that no or considerably less emulsion is applied to the margins of the web. If the web to be coated is of non-insulating material the backing roller comprises a metal core having a thin insulating surface layer. Instead of backing roller 13, two horizontally spaced rollers located along the web path, one on either side of the coating orifice together with a backing strip located between the rollers, may be provided (Fig. 3, not shown). A device for "double coating" includes a coating head (24) to which there are connected two supplies (21), (22) with a wall (29) therebetween. The outlet orifices (25), (26) are formed between said wall (29) and two adjustable members (27, 28) and a thermostatically controlled heating element (20) may be incorporated in the coating head.

Title: Improvements in and relating to tuft inserting apparatus for a brush making machine
Inventor: PARKER RUSSELL HENRY RICHARD
IPC: A46D3/04
Filed: 1959-04-10
Abstract: 885,560. Stapling. EVANS & SON (PORTSMOUTH) Ltd., J. April 7, 1960 [April 10, 1959], No. 12291/59. Class 89(3) [Also in Group XXIII] In tuft-inserting apparatus of a brush making machine, in which a reciprocating driver feeds a staple and a tuft of bristles to a brush stock and drives in the staple to anchor the tuft in a hole, grippers 18, 19 operate, when the driver 3 is in its rearward position, to grip a strip of wire and thereafter to position it transversely to the path of the driver and to move rearwardly to draw the wire strip against laterally spaced abutments 6 to form a staple in the guideway 8, Fig. 3, of the driver, where it is positioned to be fed to the brush stock on the next forward stroke of the driver. Driver 3 is reciprocated in a body member 1 by cam-operated lever 5. A tool slide 9, carrying cheek plates 10, 11 between which a tuft of bristles and a staple are driven by the driver 3, is reciprocated by a second camoperated lever 15. Slide 9 also carries a bracket 16 supporting a fixed gripper jaw 18 and a spring-loaded pivoted jaw 19. A leaf spring 24 biases bracket 16 so that a roller 21 engages a plate 22 hinged to body 1 and oscillated via a rod 25 and lever 26 by a cam 28. In operation, with the slide 9 and driver 3 in their rearward positions, the parts are disposed as in Fig. 1, jaws 18, 19 being parted by engagement of jaw 19 with a stop 29. A length of wire a is fed between the jaws. The slide and driver then moved forward. As the slide advances the jaws grip the wire and a length is severed by a knife 9a, Fig. 3. During the first part of the rearward movement of the slide, the parts assume the Fig. 2 position with the driver blade withdrawn from the gap between plates 6 and 10, 11 and with jaws 18, 19 lowered so as to draw the wire between plates 6 during the remainder of the rearward movement to form a staple which is left in guideway 8 when the jaws separate. On the next forward stroke of the driver, the formed staple is driven with a tuft of bristles, into the stock while the grippers grip a new strip of wire ready to form a new-staple on the next rearward stroke. Another embodiment is described wherein instead of the grippers being carried by the tool slide they are mounted on a separately reciprocated slide. This provides for the case when a long interval of time is required for feeding in the wire strips, e.g. when a large staple is required.

Abstract: A fuel/lubricating oil composition, suitable for 2-stroke engines, contains a major proportion of gasoline and a minor proportion of a lubricating composition which comprises a major proportion of a mineral lubricating oil having a viscosity of 150 to 228 c.s./50 DEG C. and from 1 to 10 wt. per cent of a blend of an oil-soluble sulphonate and an oil-soluble alkaline-earth metal salt of an alkyl phenol sulphide or of a phosphosulphurized alkyl phenol.  The lubricating oil is preferably a brightstock but any refined paraffinic or naphthenic oil is suitable.  Sulphonates mentioned are alkali and alkaline-earth metal salts of petroleum or synthetic hydrocarbon sulphonates having molecular weights of 300 to 500.  The preferred alkyl phenol sulphides are obtained by sulphurizing an alkyl phenol, preferably having a C4-12 alkyl group, with elemental sulphur or sulphur dichloride.  The phosphosulphurized derivatives may be obtained by replacing the sulphur or sulphur chloride by a phosphorus sulphide or a mixture of elemental phosphorus and sulphur. The additive blend preferably contains 50 to 85 wt. per cent of the sulphonate.  To facilitate dispersion in the gasoline the blend may be diluted with 100 to 140 wt. per cent of a light oil having a viscosity of 1 to 22 c.s./50 DEG  C., e.g. a spindle oil.  In examples 1.6 per cent of a blend consisting of 67 per cent calcium petroleum sulphonates (M.W. 500) and 33 per cent barium diisobutylene phenol sulphide is added to (i) a naphthenic oil of 190 c.s./50 DEG C.; and (ii) a paraffinic oil of 244 c.s./50 DEG  C. (for comparison).  The mixture were diluted with 120 per cent of spindle oil (11 c.s./50 DEG  C.) and mixed with gasoline to give a blend container 2.8 per cent lubricating oil based on the undiluted oil.
