Title: Improvements relating to valve operating mechanism for internal combustion engines
IPC: F01L1/30
Filed: 1955-07-29
Abstract: 809,027. Valve gear. SUCKLING, J. H. July 29, 1955. No. 22056/55. Class 7(6) In a valve operating mechanism, for an internal combustion engine of the type employing poppet or mushroom valves, including a first rocker arm operated by a cam to open the valve and a second rocker which acts under the influence of a cam to impart movement to the valve (or at least one of the valves if there be more than one) in a a closing direction after the valve has been opened, the second rocker is supported for a rockting movement by a plunger mounted for sliding movement in a guide, the plunger being backed by a compression spring. In Fig. 1 the valve is opened by a cam 9 and rocker 10. A second cam 16 on the camshaft 4 has part of its profile at least partially concentric to the camshaft axis. As the peak of the cam 9 reaches the arm of the rocker 10' the flat part 16a of the cam 16 is brought into concidence with the roller 29 so that the rocker 28 offers no resistance to opening of the valve 3. The flat part 16a may be so designed that when it comes into concidence with the roller 29 it allows the roller to rise to such an extent that the spring 20 will be free to raise the plunger 18 in pocket 17. The degree of upward movement may be sufficient to cause the upper end of the plunger to come into engagement with the removable cover cap 26. The cam 16 may be formed with a portion of reduced radius to enable the roller to rise sufficiently to relieve the valve 3 of the spring loading at the stage :of rising pressure in the cylinder. The valve shown is the exhaust valve. It is stated that the mechanism promotes rotation of the valve for every several thousands of revolutions of the crankshaft.

Title: Improvements in mechanism for handling boards
Inventor: BLAIR ROBERT COLVIN
IPC: B65G47/244
Filed: 1950-11-28
Abstract: 722,598. Conveyers. BRITISH PLASTER BOARD (HOLDINGS), Ltd., [formerly BRITISH PLASTER BOARD, Ltd.]. Nov. 21,1951 [Nov. 28,1950], No. 22157/53. Divided out of 722,503. Class 78 (1). [Also in Group XVI] In mechanism for handling boards of the kind comprising a stop-bar 59 pivoted transversely above a conveyer, e.g. a rollerway 58, along which boards are fed in transverse rows, and releasable locking means for holding the bar in operative position including two or more board detectors distributed across the conveyer in front of the stop-bar, the locking means is released only when all the detectors are simultaneously operated by boards so that the leading edges of the boards in a row are aligned before the boards are released. The stop-bar 59 is pivoted at 60 and depends in vertical position in which it is held against displacement by an oncoming board by two locking catches 61 pivoted at 62 on the approach side of the stopbar 59 and each having a roller 64 co-operating with the top of the stop-bar above its pivot 60. An extension 63 of each catch rests on top of the stop-bar to maintain the catch in a position in which a detector roller 65 on a downward extension of each catch is adapted to be raised by a board in position against the stop-bar. Thus when and only when two boards are side-by-side against the stop-bar and both catches are lifted, the stop-bar can pivot under the pressure of the boards to allow them to pass. A handle 66 is provided for lifting both catches at will to allow single boards to pass.

Title: Improvements in or relating to presses
IPC: B30B15/28
Filed: 1969-05-01
Abstract: 1,248,092. Punching; shearing; forging; stamping. HYDREL A.G. 1 May, 1969 [2 May, 1968], No. 22173/69. Headings B3H, B3Q and B3W. A press, e.g. for shearing or punching, comprises a fixed press member (not shown) on which a tool holder 3 is mounted, a movable press member 14 on which a tool holder 2 is resiliently mounted, a first limit switch 27 which is operated when the press member 14 is a predetermined distance from the fixed press member, a second limit switch 22 which is operated during movement of the tool holder 2 against its resilient bias and control -means (not shown) controlling the movement of the press member 14 and responsive to the sequence of operation of the first and second limit switches, the arrangement being such that, if through the presence of a foreign body 7 or a too-thick blank 6 'between the tools 4, 5, the first limit switch operates before the second the control means stops further movement of-the press member 14 towards the fixed member. The tool holder 2 is fixed to a cylindrical sleeve 17 Which forms with the piston part 14a which it surrounds a chamber 18 to which -compressed air is supplied through a line 20. Two or four sleeves 10 each movable in a sleeve 81 in the holder 2-and having a head 12 are screwed into the piston part 14a. Compressed air is fed to the chamber 18 to raise the sleeve 17 and thus the tool holder 2, tool 4 and blank 6 from its position relative to the piston 14, shown at the right-hand side of the Figure, to a position in which the heads 12 are contacted by the base of their respective recesses 11 and the tool holder 2 is raised above the piston by the distance a. In normal operation as the piston 14 is raised the tool holder 2 moves upwards, floating on the compressed air cushion until the blank 6 begins to press against the upper tool 5, when the limit switch 27, vertically adjustable on the press frame, is closed by means of a projection 30 on the piston part 14a. The holder is then forced back against the resistance of the air cushion into its lowest position relative to the piston, shown at the left of the Figure, which closes the second limit switch 22, a trip pin 24 engaging a cam surface 26 on the piston part 14a. 'If an object 7 or a too-thick blank 6 is between the tools, the tool holder 2 will be moved against its air-cushion mounting to close switch 22 before the piston movement has closed switch 27 which immediately stops the piston 14. The piston control means may be hydraulic in which case it includes an electrically-operated valve electrically connected to the limit switches. In a fine-blanking or punching press a piston presses a'toothed ring against the blank prior to blanking or punching. The air-cushion may be replaced by springs, the drive may be electromechanical and the upper press member may be the movable one. The stop mechanism can be incorporated in a swaging, forging, coining or stamping press.

Filed: 1946-07-25
Abstract: 614,703. Filling and closing bottles. BARNNETT & FOSTER, Ltd., and RAYMOND, F. G. July 25, 1946, No. 22212. [Class 125 (ii)] A bottle filling or bottle closing machine has a hydraulic cylinder and plunger for reciprocating a filling, syruping or closing head, and a second or operating hydraulic cylinder and plunger, the two hydraulic cylinders being connected by a conduit so that the two plungers reciprocate in synchronism, mechanism being provided for reciprocating the plunger in the operating cylinder, the said mechanism being adapted to yield, so as to avoid transmitting additional pressure to the plunger in the operating cylinder when a predetermined maximum pressure has been applied to the filling, syruping or closing head. As shown (Fig. 1) a hydraulic plunger 8 carries at its lower end a crowning head comprising a crown.shoot 21 with bell mouth 20, a throat 29 with liner 30, and a crowning plunger 23 slidable relative to plunger 8 against the pressure of a spring 22. The upper end of plunger 8 carries cup leathers 16, 17 and the plunger is adapted to reciprocate in a cylinder 7 carried by a bracket 6 adjustably secured to a hollow column 1 on a bottle support 3. Cylinder 7 is connected by means of a pipe 32 and column 1 to an operating cylinder (not shown), and plunger 8 reciprocates in synchronism with the operating cylinder plunger 37 which is reciprocated by a rocking lever 49 operated by a slotted cam 50 (Fig. 2). Lever 49 is formed in two parts pivotally connected on the fulcrum shaft 52 and normally held in alignment by spring-pressed toggle-links 54, 55. The maximum pressure to be transmitted to the crowning cylinder 7 is determined by adjustment of nuts 64 controlling the pressure of spring 63. When this maximum pressure is exceeded, e.g. by insertion of a bottle of excessive height, spring 63 yields and no further upward movement is transmitted to plunger 37. In an alternative arrangement, the plunger 8 carries a syruping head sliding in a guide fixed to bracket 6.

Abstract: 962,961. Floor coverings. DURASTIC Ltd. April 22, 1963 [June 15, 1962], No. 23173/62. Heading A4S. [Also in Division B5] A floor covering comprises at least two superimposed layers 4, 6, the edge of the upper layer 6 overlapping the edge of the lower layer 4, and a sealing strip 8 which occupies the space beneath the overlapping portion of the layer 6 and occupies also a space at the side of the layer 6, the strip 8 being adhesively attached to the layers 4, 6. As shown, an underlayer 3 of bitumen or asphalt (bitumen filled with mineral fillers, e.g. limestone and sand), between one half and three quarters of an inch, is applied to the floor in a continuous layer. After cooling and hardening of the layer 3, sheets 4 of the heat and sound insulating material, e.g. foamed neoprene, between one sixteenth and one quarter of an inch thick, are stuck to the layer 3 with a polyester adhesive containing a catalytic setting agent, the adjacent edges of 5 of the sheets 4 being separated by between one eighth and three quarters of an inch. After setting of the adhesive, sheets of an abrasion resistant material, e.g. ribbed natural or synthetic rubber, are stuck with the ribs uppermost to the sheets 4 by the adhesive so that the edge 7 of each sheet 6 overlaps a sheet 4 by between one sixteenth and one quarter of an inch leaving a space between adjacent sheets 6 of about three sixteenths of an inch. After setting of the adhesive, a polyester filler is forced into the gaps between the sheets 4, 6 to form the sealing strip 8. Preferably the upper surface edges of the sheets 6 are masked with tape before application of the filler or the filler is inserted by a gun which when urged against the sheets 6 prevents leakage of the material. In a modification, the sheets 4, 6 are first stuck together and this double layer is stuck to the underlayer.
