Title: Extensible fluid pressure actuated apparatus
IPC: F16D55/40
Filed: 1975-06-27
Abstract: 1483155 Slack adjusters BENDIX CORP 27 June 1975 [22 July 1974] 27334/75 Heading F2E To allow for wear in a multi-plate aircraft disc brake an hydraulic actuator therefor comprises a cylinder 42 with an end wall 58 slidable in a housing 20, a piston 40 slidable in the cylinder and variable stop means for the cylinder comprising at least one row of balls 72 extending between a fixed stop and the end wall 58, balls being successively displaced by the inner conical part 64 of the end wall as the piston advances as the braking surfaces wear to allow the cylinder 42 to advance in the housing. The piston is retracted after each brake application a limited distance by springs (not shown) and the cylinder is advanced by fluid pressure acting on the differential area of the two sides of the end wall 58. As shown the balls are disposed in two grooves 68 in a sleeve 66 which is slidable on the stem 54 of the stop member 56 by engagement of an annular abutment 78 within the piston 40 with an external abutment flange 82 of the sleeve. Displaced balls fall into the space 102 between the end wall 58 and the abutment 78.

Title: Improvements in or relating to paper folding machines
IPC: B65H45/12
Filed: 1928-09-24
Abstract: 324,377. Burdick, C. L. Sept. 24. 1923. Folding paper; gripper mechanism.-In a machine for folding paper sheets, such as Treasury notes, in which the sheets are fed singly between two series of folding-plafes, e.g. as described in Specification 178,531, the sheet-feeding, plateactuating, and sheet-delivering mechanisms are operated from a rotary member 1, Fig. 8, having suitable cam grooves thereon. The sheets are fanned out and placed in a container 63 having sides simultaneously-adjustable by a right-and-left handed screwed spindle 65. A gripper 11 and coacting anvil 13 take the bottom sheet and feed it between sets of articulated folding-plates 25a, the parts 11, 13 being carried by a slide 9 having a depending lug 7 engaging a cam groove 6 in the member 1 which is rotated by means of a belt pulley 4 or hand-wheel 5. A spring trigger 14 engaging an abutment 11<a> holds the gripper 11 open against the action of a spring 12, Fig. 3, during the movement towards the container, but is forced past the abutment 11<a> by engagement with a fixed stop 15 so as to cause the lowest sheet to be gripped. At the opposite end of its travel, the gripper 11 is opened by the engagement of a fixed abutment 17 with a crank 16 on its spindle. The folding-plates are moved into zig-zag formation to fold the sheet by links, 24 connected to the sliding spindles 25 of the end folding-plates and carried by sliding members 20 operated from a cam-groove 18 on the member 1 through a depending lug 19. The plates 25a are in two sets coupled by bars 61, 62, and the space between the sets allows a blade 33 to move upwardly and carry the sheet with it to give it a final transverse fold. The blade 33 is pivoted at 34 to a member 32 slidably coupled by a roller-and-slot connection 30, 31 to a sliding member 29 actuated from the member 1 through a cam-groove 27 and depending lug 28. As the member 29 moves in the direction away from the container 63, the roller 30 first engages and raises the blade 33, and then, having reached the end of the slot 31, causes the members 29, 32 and the blade 33 to move forward in unison, so that the sheet is carried between posts 51, 51<a> to a collecting magazine. The posts 51, 51a are pivoted at 53a so that they normally rest in the position shown in Fig. 8, but they are raised to a vertical position by the engagement of a projection 64 on the member 29 with bracket 53 on which they are mounted.

Title: Improvements in or relating to electrical data storage devices
IPC: G11C11/38
Filed: 1963-07-11
Abstract: 1,042,044. Pulse storage circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 11, 1963 [July 11, 1962], No. 27443/63. Heading H3T. [Also in Division G4] A tunnel diode 10 is connected in circuit so that its load line (Fig. 3, not shown) is such as to cause oscillation between the points 2 and 3. The oscillations are maintained by reflection along a delay line 15 terminating in the diode biasing source 16 which thus effectively shortcircuits the line. Data is stored by controlling the form of the initial oscillations. Terminal Y is rendered negative and (Fig. 4, not shown) terminal X is sent positive whenever a one bit is to be stored. When the X and Y potentials are removed the imposed pattern of oscillation will be maintained. Read out is by sending X positive and Y negative. The stored data appears on the X terminal. A clock is connected to terminal 8 and maintains the oscillation in synchronism with external circuits. The circuits may be connected to form a matrix with an X terminal common to a column and a Y terminal common to a row. Data read-out is inverted and reapplied to the X terminal to give a form of regenerative read-out.

Abstract: 770,331. Fluid-pressure blasting devices. IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 8, 1955 [Sept. 24, 1954], No. 27638/54. Class 9 (1). A fluid-pressure blasting device 5 having a chamber 11 into which gas is fed through an inlet 12 until the pressure on a closure valve 25 is sufficient to rupture a cotter pin 27 extending through the valve stem 26 is provided with a jacket 17 into which water is led through an inlet 18. From the jacket, the water escapes through outlets 19 into the borehole. Mounted on the jacket are annular members 16 holding in position a collar 15 of rubber-like sheet material, which may have metal reinforcements at the ends engaging the members 16. On inserting the device in a borehole, the water supply is turned on and passes through the jacket displacing residual air in the borehole. Gas, e.g. compressed air, is then admitted at a controlled pressure through a reducing valve 8 in the supply line 7, Fig. 1, and passes from the chamber 11 through a conduit 13 to force the collar 15 into sealing engagement with the borehole. When the water seeps through the surrounding strata the gas pressure is increased until the pin 27 fractures and the valve moves to open ports 24 through which the gas is vented into the borehole.

Title: Flame treatment of polyvinyl fluoride film
IPC: B29C59/08

Abstract: 999,550. Flame treatment of polyvinyl fluoride film; laminates and laminating. E. I. DU PONT DE NEMOURS & CO. July 17, 1963 [July 18, 1962], No. 28354/63. Drawings to Specification. Headings B5B and B5N. Polyvinyl fluoride film is rendered adherent to other materials by bringing a surface of the film into intimate contact with a moving, relatively highly thermally conductive solid surface maintained at a temperature of 70‹ to 135‹ C. and passing the film while in contact with this surface through the secondary or outer envelope or mantle of a steady flame of a burner disposed parallel to the film and transversely to its direction of travel, the flame being free from yellow luminosity. The burner is supplied with a gaseous mixture of a paraffinic or olefinic hydrocarbon fuel (preferably propane), oxygen and nitrogen, the proportion of fuel in the mixture being 0À85 to 1À05 of that theoretically corresponding to complete combustion of the mixture, and the proportion of oxygen in the total amount of non-fuel components in the mixture (chiefly oxygen and nitrogen) being 0À21 to 0À35. The distance from the free surface of the film to the discharge opening or openings of the burner is less than the length of the unimpeded primary envelope or inner mantel or cone of the flame but not less than the distance below which the velocity of the burning gases escaping from the immediate vicnity of the discharge opening or openings exceeds the burning velocity of the flame. The film is exposed to the flame for a time between 0À001 second and 0À5 second and is maintained in contact with the moving thermally conductive surface for a time after it has left the flame, whereby the average contact angle (for water) of the treated surface of the film is reduced to a value below about 40 degrees. The film may have been biaxially oriented before being treated as above. Polyvinyl fluoride films are normally extremely difficult to bond to metallic and non-metallic substrates to form laminar structures. Polyvinyl fluoride films treated according to the invention can be satisfactorily used for this purpose. In examples, aluminium panels passivated with an amorphous oxide-chromate coating are coated with a solution of an ammoniated acrylic interpolymer of n-butylmethacrylate and glycidyl methacrylate in a mixture of isopropanol, xylene and toluene and, after being heated to 190‹ to 220‹ C., the coated panels are united with P.V.F. film treated according to the invention and passed through the nip of a pair of rubber-covered rolls at a pressure of about 85-90 p.s.i.
