Title: Improvements in overhead ropeways
IPC: B61B12/10
Filed: 1951-09-26
Abstract: 691,517. Overhead conveyers. WULLSCHLEGER, A. Sept. 26, 1951. [Oct. 23, 1950] No. 22535/51. Classes 78 (iv) and 104 (ii). In an overhead conveyer system in which load containers 5 attached to a traction member 3 are led to a loading and unloading station over two guide members 18, 19 the members 18, 19 are movable in opposite directions perpendicular to the direction of motion of the member 3 so that the speed of the members 3, and the container attached thereto, at the location between the members 18, 19 may be varied from zero up to the steady continuous speed of the member 3 outside that location. As shown in Fig. 2 the members 18, 19 are rotatably mounted on slides 10, 11 movable in guides 8, 9. The slides 10, 11 are connected by wire cables 12 one of which is driven by an electric motor 24 through a cable drum 22. A switch 30 operated by a clip 6 securing a container 5 to the member 3 closes the circuit to the motor 24 to pull the slide 10 down and the slide 11 up at a speed of half the steady continuous velocity of the member 3 whereby the container is held stationary at the location between the members 18, 19. The ends of the cable drum 22 Fig. 3 (not shown) are tapered to prevent the abrupt starting or stopping of the container at the station. The slides 10, 11 as shown in Fig. 6 are moved up and down by a lever 51 and rods 50 which are moved by a motor 55 through gears 53, 54, or Fig. 7 (not shown) through separate cables actuated by synchronised motors or as shown in Fig. 8 by the pulleys 18 or 19 being clutched to a pinion 61 which thereupon moves along a rack 65. In a modification shown in Fig. 5 the pulleys 18, 19 are each rotatably mounted on a spindle 41 attached to links 40 pivoted on the slides 10, 11 and the end of the spindle 41 engages a slot 42 outwardly curved at 42a at its lower end so that the pulleys 18, 19 on reaching the lower limit of travel are moved horizontally outwardly to prevent the abrupt halting or starting of the container 5. The member 3 is normally driven by sheave 1 but should this prove insufficient the pulleys 14 and 17 may also be driven. Two or more pulleys 18, Fig. 4 (not shown) may be provided on the slide 10 in conjunction with one or more fixed pulleys.

Title: Process and means for raising sunken vessels or the like from the bottom of the sea
IPC: B63C7/06
Filed: 1926-09-14
Abstract: 281,037. Forcher, J. G. Sept. 14, 1926. Sunken ships, raising.-In raising sunken ships the lifting-apparatus comprises a buoy which has a platform for receiving a load to sink it, and which is guided down a cable to the vessel, an anchor carried by the buoy engaging an anchoring-device on the vessel. The load on the buoy is discharged by automatic means, and the vessel raised. Floats s<1>, s<2>, Fig. 1, are carried on the deck of the ship, and remain on the surface when it sinks. Guide cables Os are thus paid out. Each cable is secured at the lower end to a winch Of, Fig. 7, and passes through a lifting yoke Ob provided with an anchoring device Om and secured to the ship. The upper end of the rope is coiled on a drum Ab, Fig. 6, in the float, which also contains a depth indicator, a rope releasing-device Ac and a chamber for documents. The lifting-apparatus, Fig. 8, consists of a spherical buoy H containing a ballast chamber Ha and a diver's chamber Hb. A tube Hc passes vertically through the buoy. Articulated to the bottom of the buoy are four girders or supports Hc1 forming the ballast platform. At the cuter ends of these supports are levers Hc2, normally held at their outer ends by ropes which extend to a platform Hd at the top of the buoy, and which are provided with releasing devices Hc3. Below the buoy is suspended an anchor member Hg through which passes a rope Hhs, Fig. 1, connected to a float Hb. When the sunken vessel is located, the rope Os of the float S1 is detached and connected to the rope Hhs, and the rope Os is drawn through the anchor Hg and through the tube He. A glass lined chamber Hf, Fig. 8, in the buoy is then filled with acid. The supports Hc1 have reduced parts at their inner ends which pass into the chamber Hf, so that after a time the reduced ends are corroded and the supports released. To sink the buoy H ballast is loaded from the salvage tugsto the platform, the rope Os being connected to the float S1. On reaching the ship the anchor members Hg and Om interlock, the former being provided with spring-pressed segments. When the ends of the supports Hc1 projecting into the acid chamber are corroded away, the ballast is discharged, and the buoyancy of the apparatus raises the vessel to the surface.

Title: Improvements in or relating to clutch mechanism
IPC: F16D43/202
Filed: 1928-08-08
Abstract: 321,702. Blakeborough, R. A., Blakeborough, J. B., and Lindsay, J. Aug. 8, 1928. Clutches positive.-In positive overloading- release clutches, notches in a boss b on the driven shaft c are engaged by rollers d on the joint-pin e of toggle levers k, f, one k of each pair pivoted on a plate m<1> bolted to the driving-drum a and the other slotted to engage a pin h on a plate h' bolted to the casing. A spring i within the lever f bears on a block pivoted on the pin h and maintains engagement between the parts b, d until overload forces the rollers from the notches and the levers k, f over their dead centres, when the spring serves to complete their movement to a position in which permanent disengagement of the clutch is maintained. The lever f carries a rigid projection n pivoted to a rod o carrying a cam end o' which projects from the casing when the clutch is disengaged and may engage a trip device to break the circuit of the motor driving the drum a. The clutch is reset by pressing inwards the rods o.

Title: Improvements in machines for making wirebound boxes
IPC: B27M3/36
Filed: 1964-06-02
Abstract: 1,001,550. Making wirebound boxes. STAPLING MACHINES CO. June 2, 1964 [June 6, 1963], No. 22857/64. Heading B5D. In a machine for making wirebound boxes having stapling mechanism securing panels to cleats as shown in Fig. 1, there is provided mechanism which severs a central binding wire W between adjacent box blanks, first and second wire bending members which bend the ends of the wire W under the surface of faceboard V, and hammers and anvils which press the ends of the wires W into the faceboards V. The first wire bending member 24 (attached at the outflow end of a stapling machine) is pivoted at 30 and is engaged and rotated by the leading edge of the box blank, and a roller 26 at the upper end of the Y-shaped member 24 comes into contact with the end W 1  of the wire W and bends it down and under the surface of the panel V (Fig. 3). The member 24 is returned to its upright position by a spring 32. The second wire bending member comprises a member 112, pivoted at 114 on a bar 88 and urged to the position shown (Fig. 7) by a spring 132, which operates in phase with a loop forming mechanism. The bar 88 is adjustably mounted on a member 82 which reciprocates at the appropriate part of the machine cycle so that the wire end W 2  is engaged by a fork 116 of a member 112 as the member 82 descends and a roller 118 engages the surface of the panel C and the member 112 pivots to the position shown in chain-dot lines and the fork 116 bends the wire end W 2  round to the underside. A spring urged shoe 104 is pressed against the panel while the end is being bent. Simultaneously with the wire end W 2  being bent under the panel C, the end W 1  is clinched into the undersurface of the panel A by a hammer and anvil (Fig. 6, not shown) and the end W 2  of the preceding blank is similarly clinched.

Title: Improved continuously variable change speed mechanism
IPC: F16H39/14
Filed: 1963-06-07
Abstract: 980,837. Hydrostatic transmissions. CAMBI IDRAULICI BADALINI S.p.A. June 7, 1963, No. 22870/63. Heading F2C. A vehicle transmission of the hydrostatic type consists of concentric pump and motor units 102, 107 with swash-plate control, the motor plate 46 being continuously adjustable between zero and maximum inclination in one direction by a connecting rod 47 coupled to a plunger 15 in a control valve unit 113, while the pump plate 41 is adjustable by annular pistons 42/1, 42/2 to four positively defined operating positions at negative, zero, intermediate positive and full positive inclinations for reverse, neutral, and normal forward gear settings. The pump swash plate 41 pivots on an axis 104 offset from the pump axis. Setting of the motor plate 46 is controlled by the accelerator pedal 2 acting through a wedge-ended plunger 1 on poppet and diaphragm valves 30, 32 controlling the flow of pressure liquid through passages 50, 51, 52, 53 to a piston 18 acting on the plunger 15 loaded by a spring 24. Diaphragm 32 is subjected to the differential centrifugal pressure at ports 34/1, 34/2 in the outer and inner peripheries of an arcuate duct 35 conveying liquid from a boost or filling pump 76. Setting of the pump plate 41 is controlled by a hand lever 6 and a plunger 4 regulating the supply of liquid to annular pistons 42/1, 42/2 through a connection 43. Operation.-With the hand lever 6 set for automatic operation and the accelerator pedal 2 released, piston 42/1 engages a stop 45 and piston 42/2 moves the pump plate 41 into a position perpendicular to the pump axis for neutral setting. Upon initial depression of pedal 2 plunger 1 is moved to the right to apply an intermediate pressure to a chamber 21/2 of control unit 113 and piston 42/2 is unable to maintain the pump plate 41 in its perpendicular setting, so that piston 42/2 moves back against piston 42/1 and the pump plate 41 is then held in its intermediate arrested position for reduced forward speed. With full depression of pedal 2 the differential pressure between duet ports 34/1, 34/2 rises to its maximum value thus increasing the thrust of diaphragm 32 on valve 30, and the pistons 42/1, 42/2 are connected to exhaust to enable the pump plate 41 to move to its normal forward speed position. With lever 6 moved to the reverse position distributer 4 connects a port 51/1 to exhaust and the pump plate is moved to its maximum negative inclination. The hand lever 6 may also be moved to blockedratio and gear shifting settings. The offset mounting of the pump plate 41 and its control by pistons 42/1, 42/2, and the control of piston 15 by the diaphragm valve 32 form the subject of Specifications 980,838 and 980,839 respectively.

Title: Improvements in or relating to apparatus for recording binary information in magnetic ring cores, and for reading the recorded information without destroying the same
IPC: G11C11/06
Filed: 1958-07-18
Abstract: 839,950. Magnetic core data storage. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 18, 1958 [July 19, 1957], No. 23220/58. Class 106 (1). Binary information is recorded in magnetic cores in a form in which it can be read out non- destructively by using one saturated condition (Br<SP>+</SP>, Fig. 2) to represent one digit (" 0 " and a condition of much smaller magnetisation (B2) for the other digit (" 1 "), so that application of " read " and " reset " pulses 12 and 13 do not carry " 0 " cores off the upper straight portion of the hysteresis loop 10, and hence induce negligible voltage in an output winding, while " 1 " cores move round the loop 11 inducing a much greater output. Fig. 3 shows part of a storage matrix in which all cores of a row (say K11, K12, &c.) may first be set to 0 by source A1, and then selected cores demagnetized by synchronous damped oscillations from source Bx1 and required column sources such as By1 ( a single such source being insufficient to effect demagnetization); subsequent read-reset pulses from C1 then read out the information for amplification by D1, D2, &c. In a modification sources Bx1 &c. are eliminated and By1 &c. replaced by sources of pulses long in comparison with pulses from C1 and of such amplitude that while insufficient in themselves to demagnetize a core, when the effect of a series of read-reset pulses is superimposed a selected core is brought to a point on the loop 11.
