Title: Back hitch gantry for mobile jib cranes and the like
IPC: E02F3/48
Filed: 1962-04-06
Abstract: 970,742. Mobile jib cranes. THEW SHOVEL CO. April 6, 1962 [April 14, 1961], No. 13437/62. Heading B8B. A gantry 60, Fig. 1, for luffing the jib 17 of a mobile crane comprises a frame 61 supporting a hinge pin 44 and pivoted to the crane structure at 12 which may be raised and lowered by a telescoping frame member 62 pivoted to the crane structure at 79. To raise the gantry 60 from the travelling position shown in dotted lines the jib is lowered on to a support or the ground and a derricking cable 10 is slacked off. Locking pins 97, 98, Fig. 3, are now withdrawn, against a spring 93, from upper holes 104, which in the retracted position of inner members 72 are aligned with holes in members 73, 74. These pins are moved by a cable release 91 having an operating lever 110, Fig. 1, in the driver's cab. Winding in the cable 10 now pivots the frame 61 anticlockwise about the pin 12 and extends the telescopic frame 62. The locking pins will automatically engage lower holes 103 if the lever 110 is moved, as soon as the frame 62 begins to extend, from an over-centre position in which the pins are held withdrawn. This procedure is reversed to lower the gantry. Outriggers 5, Fig. 1, may be extended when the crane is working.
Patent GB-537208-A (GB)
Title: Improvements in or relating to photographic shutters having built-in flash lamp synchronising devices
IPC: G03B9/70
Filed: 1940-08-26
Abstract: 537,208. Synchronizing flash-lamps and photographic shutters. KODAK, Ltd. Aug. 26, 1940, No. 13469. Convention date, Jan. 23. [Class 98 (i)] In a setting-type shutter with built-in flash lamp synchronizing means, a setting-lever, after setting the master-member, is movable relatively to it, but without releasing it, to a set position in which it is held by a trigger release; after release of the setting-lever by the trigger a contact movable with it engages a fixed contact to complete the flash-lamp circuit before the setting-lever releases the mastermember to open the shutter blades, in order to allow for the lag in the operation of the lamp. In the form shown, a master-member 6 pivoted at 7 and urged in a counter-clockwise direction by a spring 9 operates the blade ring in known manner through a latch 33 pivoted to it. The setting lever L is carried by an arcuate member 16 slidable in a similar slot 17 in the shutter body. On moving it from the unset to the set position shown, a pin 14 carried by it operates in a slot in the master-member to rotate this member to its set position, after which the pin moves out of the slot and rides over a shoulder 13 latching the master-member. The lever L is latched against the action of a return spring 18 by one arm of a bell-crank lever 23 which engages a lug 24 on the arcuate member 16. On depression of the release trigger 5, a nose 28 on it engages an upturned ear 29 on the other arm of the lever 23 which is rocked to release the arcuate member 16, and with it the setting- lever L, which then move to the left, under the action of the spring 18. During the first part of this movement, while the pin 14 is riding back over the shoulder 13 of the mastermember, which is still latched by it, a contact member 42 on the arcuate member 16 wipes past the end 43 of a spring contact member 40, and completes the flash lamp circuit. Subsequently the pin 14 enters the slot in the mastermember, which then operates the shutter blades. To prevent closure of the lamp circuit on setting the shutter, the end 43 of the contact member 40 is normally retracted from the path of the member 42, but when the trigger 5 is depressed to make the exposure an insulated lug 47 on it engages the member 40 and forces the end 43 into the path of the contact 42. The interval between the closing of the lamp circuit and the operation of the shutter blades may be varied by adjustment of the speed of movement of the setting-lever by varying the tension of the spring 18, for which purpose the pin 19 to which the spring is attached is adjustable along the periphery of the shutter casing. The electric leads are connected by means of a plug 52, one connection being by way of the metal body of the plug and the metal parts of the shutter to the contact 42, and the other by way of a central insulated prong in the plug which contacts with the insulated spring contact member 40. Specification 540,476 is referred to.

Title: Improvements in steadying devices of rolling of ships
IPC: B63B39/06
Filed: 1920-05-17
Abstract: 162,927. Mitsubishi Zosen Kaisha, Ltd., and Motora, S. May 17, 1920. Planes and auxiliary surfaces for preventing and damping rolling.-A device for minimizing the rolling of ships of the type comprising withdrawable projecting fins adapted to turn on an axis perpendicular to the ship's side under the control of automatic means actuated by the rolling of the ship, has the fin a and its axle of rotation b rigidly connected, both members cooperating in the withdrawal movement which is effected by the controlling engine. The automatic means may consist of a gyrostat operating on an electric-light switch which controls the current through a relay switch and thus energizes the solenoids which operate the differential valve i of the controlling-engine h, of the steam steering type. As shown in Fig. 1, the fin a is integral with a hollow shaft b screwed internally at the inner end to receive the spindle s, and fitted with a bearing c at the outer end constrained to travel during withdrawal without rotation, by means of the guides d in the recess e. The controlling-engine h drives the shaft k which carries two loose spur wheels m, p, through the worm-wheel l and either turns the fin through the spur-wheels m, g, when the wheel m is locked to it bv means of the clutch o, or draws the fin into the recess when the wheel m is locked to the frame n by the clutch t<3> and the clutch q is moved to lock the wheel p to the shaft k. The clutches o, t<3> are operated by the wheel t which is screwed to operate the screwed spindle t<1>. In the arrangement shown in Fig. 6, the fin axle b is journaled in a shaft c carried in bearings e, d in the recess in the hull. A shaft k, in line with the shaft c, carries a bevel-wheel sector p gearing with a corresponding sector q fitted to the fin a. The controlling-engine shaft drives the vertical shafts j, o through bevel-gearing, the vertical shafts driving the shafts c, k through worm gearing i, h and n, m. By means of a clutch on the engine shaft, the shaft k can be rotated independently of the shaft c so as to incline the fin, or both shafts k, c may be rotated together to fold the fin into the recess.

Title: Improvements in and connected with suction devices for artificial dentures
IPC: A61C13/24
Filed: 1922-05-16
Abstract: 202,390. Everett, S. J. May 16, 1922. Teeth, artificial.-Relates to suction devices for artificial dentures and to a form of attaching stud for use therewith, wherein the stud is provided with a base-plate. According to the invention the head of the stud is placed in a recess in the die plate used in the moulding process, so that its base plate closes the mouth of the recess, a wrapping of tin-foil or other flexible material is placed over the die-plate and stud to prevent the ingress of the vulcanite into the recess during the moulding, this wrapping being arranged to leave uncovered the centre portion of the stud, which forms the anchor. Either solid or hollow studs may be used and they may be formed of a plurality of parts. As shown in Figs. 1 and 7, a hollow two-piece stud c is employed which is mounted in a lead die-plate e, a " polishing- plate " of thin sheet tin being first inserted in the recess, the mouth of which is closed bv the base-plate d having its edge bent in places to form anchoring means m. The assembled die-plate and stud are then wrapped in tin-foil, the preferred method involving the use of an annulus h, Fig. 5, of foil which leaves the base-plate d free, this being covered by a centrally perforated disc of silk j, Fig. 6, underlying the foil and leaving the anchoring means exposed to the vulcanite. The die-plate and stud are pinned to the plaster mould in the usual manner by pins k, and the packing and vulcanizing is carried out, after which the die-plate may be released and the tin foil removed together with any projecting portions of the silk. A suction disc n may then be attached to the stud which is left with a solid vulcanite neck l with a polished top. A solid stud is shown in Fig. 10 composed of a head o and integral neck p and shank q, over which a base-plate r is slipped together with an anchoring ring s, the shank being riveted over, enlarging the head of the anchoring ring and thus forming an undercut stud to grip the vulcanite. This solid stud is then placed in a die-plate t and a central silk disc w placed over the base-plate r, a tin-foil annulus v of internal diameter equal to that of the base-plate then being applied to enwrap the whole assemblage which is attached to the mould and subjected to the usual subsequent operations to form the denture around the stud.

Abstract: 1,154,526. Superconductive circuits. SIEMENS A.G. 28 March, 1967 [29 March, 1966], No. 14007/67. Heading H3B. A superconductive data store comprises column (bit) and row (word) write lines 1, 2 on one side of a superconductive layer 3, and superconductive read-out lines 4 on the other side of the layer, each read-out line 4 extending parallel to a column write line 1 and including portions positioned diagonally at respective crossing points with the row write lines, each portion being shunted by a respective cryotron 5. To write in at a given location coincident signals are applied to selected row and column wires, and a local flux is set up in the superconductive layer the direction of which depends on the bit, 0 or 1, to the stored. The local flux is either parallel with or transverse to the adjacent diagonal portion of a read line, and so causes it to switch to the normal conductive state, the resistance of the portion being larger if the flux is parallel than if the flux is transverse. To read out a given word non-destructively, the cryotrons 5 along a row are switched to the resistive state by current in a word line 6, the identity of the data stored in each location along the selected row being then denoted by the resistance between the ends of the associated read-out line 4.

Abstract: 419,676. Directive wireless signalling. SUTTON, C. F., Royal Aircraft Establishment, South Farnborough, Hampshire. May 17, 1933, No. 14212. [Class 40 (v).] A loop aerial 1, Fig. 1, is periodically switched in and out of circuit with a non-directional aerial 2 so that on one side of the switch the two aerials are combined, and on the other side the non-directional aerial alone is across the input of a common amplifier 7, 11, the output of which contains a milliameter 12 to give a visual indication of the bearings. The arrangement is designed to nullify the effect of varying field-strength. The needle of the meter 12 is first set to a standard mark on signals received on the aerial 2 by means of a volume control 10. The switch 8 is then opened and closed, a similar volume control being provided at 9. If the meter shows no deflection, the loop 1 is in the minimum position ; otherwise a deflection occurs showing the pilot of an aeroplane, for instance, whether he is flying to the right or left of his course. A plug 23 feeds other meterindicators at different points on the craft. Fig. 3 shows a modified arrangement in which the switching is performed automatically by a local oscillator 20 which periodically switches the valve 11<x> and the loop 1 out of circuit, the bearings then being indicated by the difference in reading of the two meters 12, 12<x>. The detector valve 11, Fig. 1, may be replaced by a diode, and the switching may be performed by a pair of relays (Fig. 4, not shown), one of which is slower in action than the other, the loop aerial being flicked into circuit during the interval.
