Filed: 1971-12-22
Abstract: 1334290 Clearing blocked pipes G TASH 22 Dec 1971 [21 Jan 1971 16 June 1971] 59607/71 Heading F2N A device for clearing a blocked pipe 22 (Fig 2), comprises a tube 11 (Fig. 1), of resileint material, a valve assembly 13 which normally either closes one end of the tube 11 or leaves open only a small part of the cross-sectional area of the tube at this end, and a fitting 12 for connection with a source of high pressure water. In use (Fig. 2), the tube 11 is expanded by the high pressure water into sealing engagement with the pipe 22, thereby isolating a section of the pipe between the blockage and the device, and then the valve 13 opens to admit high pressure water to the isolated pipe section to clear the blockage. When the valve 13 shown is closed (Fig. 1), a small flow passage via orifice 20 and hollow section 15 remains open. The valve opens when the tube 11 expands to clear valve head 14 and permit flow via space 21, apertures 19 and hollow section 15. In a first modification, Fig. 3 (not shown), the valve comprises a disc, permanently engaged around its periphery by the tube 11 and formed with a central aperture, normally closed by a spring urged ball, the latter being moved away from the aperture against the spring by pressure within the tube, when this pressure exceeds a certain value. In a second modification, Fig. 4 (not shown), the valve comprises an apertured disc, normally engaged around its periphery by the tube wall, but permitting flow between its periphery and the tube wall when the latter is expanded by water pressure. The device may include a length of wire, nylon or cotton extending through the tube 11 and secured to the ends of the tube to limit longitudinal extension of the tube.

Abstract: 1342745 Drilling machines ROBERT BOSCH GmbH 16 Dec 1970 [22 Dec 1969] 59615/70 Heading B3C [Also in Divisions B4 and F2] A drill including a hammer 18 for applying impacts to a tool holder 7<SP>1</SP>, the hammer being axially reciprocated by an electric motor via gear-wheels 10 and 12 and air cushions 21 produced between the hammer and an axially movable cylinder 16, comprises means for enabling or disabling rotation of a member 34 having internal longitudinal splines which engage with longitudinal external splines on the holder 7<SP>1</SP>. The means includes a gear-wheel 23 fast with gear-wheel 12 and meshing with gear teeth 24 on an annular drive body 25 which includes longitudinal bores 52 equally spaced circumferentially and each accommodating a compression spring 55 and balls 54 which are engageable in recesses 53 in annular members 27, 28 which form a bearing for the drive body. The under surface of the member 28 forms one part of a dog clutch. The other part 39 of the dog clutch is formed on the upper surface of an annular member 37 which is non-rotatable, but axially movable, relative to a shaft 31 carrying at its upper end a pinion 32 which engages with gearteeth 33 on the member 34. A sleeve 42 mounted on the member 37 has a projection 43 extending into a key way 44 in housing 9 and a coarse external thread which meshes with a coarse internal thread 46 on a switch member 47. In operation with the switch member moved in one direction to a position in which the dog clutch is engaged, the drill has a rotary/percussion operation and any overloading of the drill is relieved by the balls being cammed out of their recesses to permit the body 25 to rotate relative to the members 27, 28. Movement of the switch member in the opposite direction will cause sleeve 42 and thus member 37 to move axially relative to the shaft 31 so as to disengage the dog clutch, thus conditioning the drill for percussion only. The drill which has a handle (2) (Fig. 1, not shown) may be provided with a second handle 8. In alternative arrangements the hand grip portion (58) is rotatable relative to the portion (57), and the flange (59) is coupled by meshing gears or a pin-and-slot connection to the switch member so that the switch member can be moved upon rotation of the hand grip. The hand grip portion may be axially aligned with the switch member. Reference has been directed by the Comptroller to Specifrcation 1,206,853.

Patent GB-788810-A (GB)
Abstract: 788,810. Taping machines. PIRELLI SOC. PER AZIONI. June 13, 1955 [Sept. 6, 1954], No. 16916/55. Class 109 [Also in Group XVI] A taping machine for taping electric cables in which rolls of tape rotate about a cable has the tension of the tape controlled by means which take up slack that may develop when the machine is stopped. Each tape roll is controlled by a mechanical brake actuated by a spring which is opposed by forces proportional to the pull of a second spring and the winding tension in the tape. A roll 4 (partially shown) of paper is rotatably mounted about a pivot 7 and braked by a band 8 with one end fixed at 10 and the other pivoted at 11 to a lever 21 to one arm of which is attached a spring 22 that tends to apply the brake. A rod 25 pivoted to a control lever 27 has a slot in which is received a pin 23 on an arm of the lever 21. Pressure exerted on the pin 23 by the rod 25 under the influence of tape passing over a roller 29 on the control lever 27 (piovted at 28) tends to release the brake. When the pressure from the tape is released due to slackening, the brake is applied and slack is taken up by movement of the lever 27 under the influence of a spring 30. The slot in the rod 25 allows slack to be taken up after the brake has been fully applied. To stop the machine in case of breakage or complete relaxation of the tape, a pivoted lever 34 is arranged to be struck by the lever 27. whereupon an arm 37 is displaced allowing a second arm 39 to rotate under centrifugal force to a position in which it encounters another lever to close an electric contact. In order to accommodate a wide range of tensions by the springs 22, 30, sets of springs of different values may be provided.
