Title: Improved service pipe coupling, method and tool for making same
IPC: F16L19/04
Filed: 1970-12-15
Abstract: 1,271,169. Forming pipe couplings. MUELLER CO. 15 Dec., 1970 [16 Dec., 1969], No. 59512/70. Heading B5A. [Also in Division F2] In a pipe joint (see Division F2), which in-  cludes a coupling nut 12 and a tubular member 14, Fig. 4, a permanent annular bead 42 having an inwardly projecting lip 44 is formed on the end 38 of a plastics pipe, while the pipe is positioned within the coupling nut, by applying pressure in a radially outward direction, indicated by arrows A, Fig. 4, to the interior circumference of the pipe. The bead 42 loosely traps the pipe in the nut 12. The plastics may be polyethylene, P.V.C., polybutylene or polypropylene.  The formation of the annular bead 42 is effected by an apparatus 50, Fig. 5, whose mode of operation is as follows: a mandrel 56 is inserted into the nut 12, Fig. 10, and the apparatus secured to the nut 12 by an externally threaded tubular nut 52. The pipe P is inserted in the nut 12, so that the end 38 of the pipe abuts a flange 64 on the mandrel 56, and is held in this position by suitable clamping means 90. A cam 58, disposed in a slot 70 in the mandrel 56 is fixedly mounted on a shaft 72, and the shaft, extending through an offset bore in the mandrel 56, is connected to a handle 74. When the handle 74 is rotated in one direction, the slot 70 houses the cam member 58 therein, Fig. 9 (not shown). Rotation of the handle 74 in the opposite direction causes the cam 58 to extend radially outwards to engage the interior of the pipe P. Further rotational movement of the handle 74 causes the mandrel 56 and cam 58 to rotate as a unit, with pressure being applied by the cam 58 radially outwardly to the interior of the pipe to upset the same to form the annular bead 42.
Patent GB-1214198-A (GB)
Title: A programmed apparatus for the serial handling of numerical information
IPC: G06F7/495
Filed: 1968-12-20
Abstract: 1,214,198. Data processor. FRIDEN HOLLAND N.V. 20 Dec., 1968 [22 Dec., 1967], No. 60781/68. Heading G4A. Digital electric calculator has a delay line memory 2 connected in a closed loop with a calculator unit 1 containing an adder-subtractor 6 and a shift register 5, the delay line containing numerical words interlaced with corresponding digits of each word adjacent each other, the digits being composed of a predetermined fixed number of bits and the register having an equal number of stages. The delay line shown contains eight registers each holding a twelve-digit binary coded decimal number. The digits pass via an amplifier 3 to a series of switches in the calculator unit. To perform an addition or subtraction on adjacent digits the first digit to be operated on is fed to the shift register. When the first bit of the following digit leaves amplifier 3 it is fed to the adder-subtractor 6. At the same time the first bit of the earlier digit leaves the shift register to enter amplifier 4 and is also fed to the adder-subtractor. The addersubtractor output is at the same time connected to the shift register input so that the sum of the input bits is stored in the shift register. At the end of the arithmetic operation the switches are arranged to feed the data through the shift register. Any corrections required to produce appropriate carries are carried out on the next circulation when a 6 is added to or subtracted from the b.c.d. number via input d where necessary, any carries to the next digit being held in flip-flop 8. If two spaced digits are to be operated on, for instance the digits in the first and fifth registers, then the digit of the first word is passed by the shift register to enter the delay line but when the digit of the second word is in the delay line the remaining words are connected to pass via the unit 6 until the digit of the last word has passed, the second word digit meanwhile recirculating in the shift register and then the second word digit is added to the end of the group containing the corresponding digits. Thus the register digits are in the order 2.6.5.4.3.1. This is repeated until the required digits are adjacent.

Title: Improvements in or Relating to Impact Tools and Like Percussive Apparatus
IPC: B25D9/14
Filed: 1980-05-27
Abstract: An impact tool has a tool bit 16, and a reciprocable mass 10 movable in one direction by a pressure pulse in a chamber 34 against the action of liquid pressure in a chamber 60 and in the opposite direction by the pressure of the liquid in chamber 60 to apply impact to the tool bit 16. The mass 10 acts on the liquid through an intermediate plunger 54 of smaller dimensions and the mass is able to perform limited movement before striking the plunger 54. High pressure liquid from duct 71 moves piston 82 leftwards against gas spring 90 and then moves spring 90 rightwardly to apply high pressure to chamber 60 via duct 38. The movement of piston 92 rightwardly causes the gas spring to move piston 82 rightwardly thereby removing the high pressure on piston 120. Piston 116 is thus moved leftwards to connect duct 38 to exhaust via duct 144 and thus end the high pressure part of the cycle. <IMAGE>
