Patent GB-1346400-A (GB)
Title: Fluid-operated rotary tool
IPC: B25B21/00
Filed: 1972-08-03
Abstract: 1346400 Power tools INGERSOLL-RAND CO 23 Aug 1972 [8 Sept 1971] 39246/72 Heading B3N A fluid-operated rotary power tool comprises a casing 2, a fluid motor 3 driving a spindle 9, a passage extending from a fluid pressure source to said motor, a valve member 37 in said passage which is movable from a first closed position, Fig. 1, to a second position. Intermediate said positions, Fig. 3, fluid can flow along said passage and a movable annular valve seat 42 is slidable along said passage and can engage said valve member in its first and second positions. The movable valve seat is normally located where it will engage the valve member in said second position, Fig. 4. When the movable valve seat and the valve member are engaged fluid flow is stopped, and pressure of said fluid holds the movable valve seat against said valve member during the movement of said valve member from said second position to said first position and spring means 43 urge the movable seat away from the valve member. In operation the tool is pressed against a fastener and the spindle 9 and thus push-rod 34 and valve member 37 are moved rearwardly. This allows fluid to pass to the motor. At a predetermined torque balls 25 of clutch 14 move out of their recesses and move push-rod 34 rearwardly. This causes valve member 37 to engage sleeve 42 and shut off the fluid for the motor. When the tool is removed from the fastener the parts return to their initial positions except for sleeve 42 that stays engaged with valve member 37 through fluid pressure. The sleeve moves to its start position when leakage past the sleeve reduces the said pressure. Fig. 7 shows an alternative construction of sleeve whereby valve member 37 seats inside the sleeve to shut off fluid flow. The inside surface of the sleeve may have a resilient lining.

Title: Improvements relating to cranes, grab cranes and the like
Inventor: FRANKLIN ARTHUR ERNEST
IPC: B66D1/22
Filed: 1956-11-27
Abstract: 863,307. Winch controls. PRIESTMAN BROS. Ltd. Nov. 27, 1957 [Nov. 27, 1956; July 29, 1957], Nos. 36283/56 and 23974/57. Class 78 (5). [Also in Group XXIV] A winch drum on a crane, especially a grab crane, is driven in opposite directions by two clutches controlled by movement in opposite directions of a single lever which also controls a brake on the drum. In the form shown, the drum 1. Fig. 1, is mounted on bearings 2 on a shaft 3 driven from a wheel 4, and may be driven through an epicyclic gear train 46, 45, 47, of which the sun-wheel 46 is keyed to the shaft 3, by applying a braking force to the planet carrier 49. This rotates the drum in the opposite direction to the shaft and at a reduced rate. Alternatively, the drum may be clutched directly to the shaft by braking a drum 57, Fig. 3, loose on the shaft 3 and connected by a link 70 and bell-crank 69, 67, pivoted at 68 to the driving wheel, to a band 59 whose end 65 is attached to the driving wheel. Braking the drum 57 causes the band 59 to tighten on a drum 60 attached to the rope drum 1, and hence to clutch the drum 1 to the driving wheel 4. A brake drum 42 is also attached to the drum 1. In a modification, Figs. 4, 5, allowing both clutches to be located at the same end of the rope drum, the rotating band 101 is attached to the planet carrier 83 instead of to the wheel 4, and the bell-crank 97, 99 has one arm on each side of the planet carrier. Braking the drum 95 causes the planet carrier to be locked to the annulus and hence the whole epicyclic train is locked solid and the drive is transmitted direct from shaft 3 to the rope drum. In either embodiment the clutches are controlled by a single lever 10, Fig. 5, pivoted at 11 so that movement to position 10a tightens the band 90 and movement to position 10b tightens the band 81 on to the planet carrier. In either end position the lever 10 is locked by a gravity biased arm 20 engaging a lug 23 on the lever. Depression of the brake pedal 25, also pivoted at 11, causes a link 30 to be rotated about its pivot 21 so that a pin 31 lifts the arm 20, allowing the lever 10 to return to its central position. Specification 834,487 is referred to.

Title: A method of pushing trucks on to a mine cage or on to a tipper or like device
IPC: E04H6/42
Filed: 1961-10-10
Abstract: 998,201. Discharging trucks from mine cages. SCHUCHTERMANN & KREMER-BAUM A.G. FUR AUFBEREITUNG. Oct. 10, 1961 [Oct. 15, 1960], No. 36394/61. Heading B8E. As a truck b is pushed from a mine cage 3 a truck stop 6, 7, 8, is moved in the same direction as the truck at a lower speed so that the truck gently contacts the stop and is retarded gradually. A pusher 2 pushes a car a into the cage and the car b out at the other side with the truck stop in position A. When an axle 13 of the truck b approaches catch hook 7 a motor 10, automatically controlled by a switch 15, drives the truck stop in the same direction as the truck b is moving. The truck b runs over the hook 8 and catches up with and accelerates the hook 7. This operates an under voltage relay 16 which reverses the motor 10 and slows down and stops the trucks at the position shown. The pusher 2 is next returned to its original position and the motor 10 is restarted by a time relay 19, thus accelerating the truck b through a distance Y away from the cage. The hook 7 moves downwards along a curved path 12 to permit the truck to continue its motion. Finally, the motor 10 is again reversed to return the truck stop to the position A. To speed up operation a wheel-stop 20 may be provided in the cage and in this case the truck b need not be completely stopped, the motor 10 merely being reversed to slow down the truck and then operated in the original direction to move it away.

Title: Register device for sheet feeding mechanism
IPC: B65H9/10
Filed: 1955-12-22
Abstract: 786,395. Feeding sheets, ADDRESSOGRAPH-MULTIGRAPH, CORPORATION. Dec. 22, 1955 [Sept. 9, 1955], No. 36832/55. Class 100(1) Sheet-registering devices. In rotary printing-machine wherein sheets are fed towards the printing-cylinders 16, 17 by a conveyer 21, the sheets are each registered at the front on a table 20 by front stops 25, and side-registered against an abutment plate 40 by a reciprocating sucker 30 which subsequently slips over the sheet when the latter meets the plate 40. The sucker 30 is vertically adjustable in a body 31 secured by a screw on a transverse rod 32 carried in a pair of arms 50 pivoted at 51 to the machine side frames 15. One arm 50 is oscillated by means of a cam 52 on the cylinder 16 to impart vertical movements to the sucker 30, and the rod 32 is also reciprocated axially through a cam 91 on the cylinder 16, and a bell-crank lever 93, to enable the sucker 30 to move the sheets sidewise, against the abutment plate 40. The plate 40 is carried by a body 41 secured by a screw on a transverse rod 33 also carried in the oscillating arms 50. The sucker and plate bodies can be slid along their respective bars for operation at the opposite side of the machine. Vertical. adjustment of the plate 40 relative to the body 41 is effected by rotating an eccentric pin engaging a slot in the plate. Lateral adjustment of the body 41 along the rod 33 is obtained by a micrometer screw 76 mounted in a bracket 70 adjustably secured on the rod 33. Suction is established to the sucker 30 through a valve 83, pipe 84. rigid T-pipe 81 secured to the body 41, and pipe 80. The T-pipe 81 communicates with atmosphere through a passage in the body 41 which is controlled by a needle valve 85 (not shown), whereby the. degree of vacuum established at the sucker 30 can be controlled. The valve 83 may comprise a relief valve controlled automatically, by the movements of the bell-crank lever 93 and a slotted connection 101, such that the application of suction to the sucker 30 is released when the latter leaves the sheet in contact with the abutment plate 40.

Title: Improvements in or relating to pumps
Inventor: SILVER ROBERT SIMPSON
IPC: F04D29/10
Filed: 1956-12-05
Abstract: 888,211. Stuffing-box substitutes. WEIR Ltd., G. & J. March 5, 1958 [Dec. 5, 1956], No. 37104/56. Class 122 (5). A fluid seal incorporated in a reciprocating or rotary pump comprises a housing 1 penetrated by the pump shaft 2 and formed with a convergent-divergent passage 4, 5, and auxiliary passages 6, 9 debouching into the convergent passage 4 and connected, respectively, to operating and auxiliary fluid sources. As applied to a boiler circulating pump, the operating fluid, which may be steam or highpressure water at saturation temperature, is fed through an inlet 7A, annular duct 7 and passage 6 of divergent or convergent-divergent form, and the auxiliary fluid, which may be cold boiler-feed water, is fed through an inlet 9A, annular passages 9 and convergent passage 8. The fluid in its transit through the passage 6 expands, loses pressure, becomes partially converted into steam (when the fluid is saturated water) and leaves the divergent passage 6 at high velocity. Cold water is thus drawn through the passages 9, 8 and caused to surround the mixed stream of water and steam issuing from the passage 6 and, as a result, all or most of the latter steam is condensed. The energy of the condensed steam is communicated to the cold water in the passage 8 and a stream of water is therefore directed at high velocity through the passages 4, 5 into the pump chamber 13 ; in this chamber the pressure of the water is greater than that of the pump discharge water thereby preventing leakage of the latter along the shaft. During starting, uncondensed steam may escape to atmosphere through a gap 10 between the convergent passages 4, 8, overflow chamber 11 and non- return valve 12.

Filed: 1971-08-13
Abstract: 1333809 Automatic exchange systems SIEMENS AG 13 Aug 1971 [18 Aug 1970] 38039/71 Heading H4K  Four wire connections are set up through a folded two wire network by dedicating certain pairs of appearances for 4-wire devices and adopting one of these appearances permanently for the Go direction and the other for the Return direction. The 4-wire trunks may be incoming K, bidirectional D, outgoing G or special bidirectional L, these being special in that signalling in respect thereof is effected over dedicated data trunks so that they need not be terminated in relay sets but can appear directly on the network. This situation arises when exchanges of different type become connected in tandem. A marker M apprised of call details via register connector AK1 or via the not shown data trunk selects the shortest path between the Go terminal say hll of the calling device K and a point in the network which is also accessible to the Return inlet, e.g. h32 of the called device G say. ln the case shown, the selected path is kf1 (this of course being the only path between a designated inlet on the left of the network and a designated outlet on the right of the network). When the device K determines that the path has been switched through, it brings up relay X in the marker so that another path kf2 may be selected between the two inlets h12 and h31 which are always associated with the previously processed inlets All and h32. When this path cuts-through, the marker and couplers AK release. Two wire connections may be set up via the same network. It is emphasized that the network falls within the type especially known as an inverse or reverse grouping network and that the main characteristic of such a network is that every two wire terminal (which includes, as separate entities, both terminal pairs allocated to 4-wire connections) is connected to every other terminal solely via the switches of the switching network, i.e. with no intervening links, registers &c., all the terminals being located at one side of the network. Reference has been directed by the Comptroller to Specification 1,001,902.

Abstract: 816,637. Control systems for heating resistances. PROCTOR ELECTRIC CO. Dec. 14, 1956 [Dec. 22, 1955], No. 38207/56. Class 38 (4). A control system for an electric heating unit having at least two heater elements comprises a switch whereby a single actuating member serves to effect either energization of a single one of the heater elements or the energization of two elements in parallel and also to adjust the ratio between the energization and de - energization times of the heater elements. An electric heating device 10 comprises two heater elements 13, 14 connectable to a mains supply 11, 12 by means of a switch 15 having an actuating knob 16. The switch 15 has four cam members, cam 19 operating a main ON-OFF switch 18, cam 23 effects the energization of a single or the parallel connected elements, cam 26 adjusts the ratio of the closed and open times of a cycling switch 25 whilst the indent cam 35 serves as a positioning member for certain positions of the knob 16. Movement of the knob 16 to effect clockwise movement of the cams closes the switch 18, the cam 26 gradually increasing the contact pressure of the switch 25 by the rise of the cam 26 from O to A, thereby increasing the energization of the heater element 13. During this part of the movement the heater element 14 is out of circuit since the cam 23 has not yet closed switch 22. Further clockwise movement of the actuating knob 16 causes the cam 23 to close the switch 22 to put the two heater elements 13, 14 in parallel and to bring a differently calibrated part of the cam 26 into association with the cycling switch 25 so that the contact pressure of the switch 25 is governed differently for the two elements 13, 14 in parallel than for the element 13 alone. The indents 36 on the cam 35 correspond to set control positions such as " SIM," " LO," "MED," " HI " whilst the projection 37 thereon ensures that, when the element 14 is switched in, the operative point on the cam 26 must move from A to B. In a further embodiment the control knob is movable in either direction from a central " OFF " position when it is desired to use either one or the two elements. U.S.A. Specifications 2,623,137 and 2,673,444 are referred to.
