Title: Method of and apparatus for laying a pipe line
IPC: E02D17/08
Filed: 1976-04-23
Abstract: 1521812 Trenching apparatus GEWERKSCHAFT EISENHUTTE WESTFALIA 23 April 1976 [30 April 1975] 16580/76 Heading E1F [Also in Division F2] Apparatus for use in laying a pipeline has a crib-shield 11 consisting of a framework 14 which supports cutter planks 15. A plurality of double-acting hydraulic piston and cylinder units 17 are connected between frame 14 and a further movable frame 16. The apparatus thrusts pipe lengths 13', 13 together by two devices 21. These devices comprise parts 22, 23 adjustably connected by pin 24 and have a head piece 25 that is of yieldable material or has a yieldable end face. The devices are connected to frame 16 by an upper pivot, not shown, and a lower locking pin 31. This pin 31 can be removed to allow the devices to be pivoted outwardly to allow a pipe section to be lowered. In operation plank or planks 15 are connected by pins to frame 16. Hydraulic units are operated to move frame 16 and the respective planks forward. The plank or planks are disconnected and frame 16 returned to its start position. This operation is repeated until all the planks have been moved forward. The loosened trench material can then be removed by a digging machine 20. Frame 14 is moved forward by connecting all the planks to frame 16 and operating units 17. A pipe section can now be lowered into the trench. Devices 21 are pivoted into an engaging position which is between the trench bottom and the centre line of the pipe section. Any planks connected to frame 16 are disconnected and units 17 operated so that frame 16, devices 21 and pipe section 13' are moved rearwardly.

Title: Battery charger protection circuit
IPC: H02J7/00
Filed: 1964-04-22
Abstract: 992,217. Battery charger protective systems. REPCO RESEARCH PROPRIETARY Ltd. April 22, 1964 [May 1, 1963; Dec. 24, 1963], No. 16617/64. Heading H2H. A battery charging system is provided with a device connected between the charging source and the battery with a short-circuiting contact across the device, the arrangement being such that the short-circuiting contact is opened when an abnormal condition exists in the charging circuit. As shown in Fig. 1 a lamp L and the operating coil A1 of a relay are connected in series between a battery (not shown) and a charging source, a contact CA2 of a further relay forming a short circuit BP across the lamp and, if desired, part of the coil A1. The operating coil A2 of the further relay is connected in series, inter alia, with the contact CA1 of the first relay in a shunt circuit across the battery. When the battery is charging the coil A1 will be energized to close contact CA1. but the voltage across the winding A2 will be insufficient to energize it. Contact CA2 will then be open and the charging current will be limited by the lamp L. As the battery is charged the battery voltage will rise whereupon the coil A2 will be energized to close contact CA1 and the normal charging current will flow. Should any abnormal condition exist at the battery terminals such as a short-circuit or a reversely connected battery coil A2 will not be energized. Thus the lamp L will limit the flow of current. If desired, the lamp L may be replaced by a resistor. A resistor R and a switch S may be included in the shunt circuit to enable the apparatus to be used for both 6 and 12 volt charging. In other embodiments the charging source may be A.C. and the charging circuit include rectifiers and transistors.

[Also in Division B1] In an apparatus for removing dust and broken granules from a grannular material, so that the material can be re-used in an industrial process, the material from the process is discharged from a transport container 7 into a shoot 6 from which it passes through a spillway 9 to a conveyer 11 discharging through another spillway 12 into a vibrating screening device 14. The screened granules are discharged through spillways 16 into receptacles 17 for re-use, and dust from the screening device collects in a hopper 19. A pump 20 induces suction at the spillways 9, 12, 16 and the dust from these points is removed in dust traps 26, 27 and in a separator 21. If necessary the path of the granules may be blanketed by an inert gas, such as nitrogen, from a tank 33 in order to exclude air and moisture when e.g. the granular material is a catalyzer.

Abstract: 884,797. Coating with metals, deposited electrophoretically. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 16, 1960 [May 22, 1959], No. 17501/59. Class 41. A coating of metal is formed on a metal surface by depositing the coating metal by electrophoresis from a suspension of the finelydivided metal in an organic liquid, and then heating the coating to remove the liquid and consolidate the coating which may form an alloy with the substrate metal. Finely powdered Al, Sn, Fe or alloys of 1-10 microns particle size are suspended in a polar solvent, e.g. denaturated alcohol, together with a small amount of tannic acid and salts of the metal being deposited to act as conductor, e.g. AlCl 3  and Al(NO 3 ) 3  in the case of powdered Al. The substrate metal may be iron, steel, or copper and is pre-treated with NaOH, HC1, washed and dried. An undercoat of indium may then be applied. In a suitable apparatus, a cleaned low carbon steel strip 15, passes over a conductor roll 1 and under an insulated sink roll 2 immersed in a shallow tank 3 containing the electrophoretic bath. A deposit of aluminium is formed on both sides of the strip at a C.D. of L.A.S.F., passing between aluminium anodes 4, 5. The coated strip emerges and is supported by a second conductor roll 7, while passing through a drying chamber 6, where the alcohol is vaporized and recovered. The coated strip then enters a rolling mill 9 which may be heated to partly consolidate the coating, and is then fully heat-treated and annealed in a lead bath 11 at 350‹ C., a tower 12 containing a reducing gas and maintained at 700‹ C., where after 0.3 to 1 sec. treatment the coated strip enters a second lead bath 13 at 350 ‹ C. After cutting and coiling the strip is maintained at 250‹ to 450‹ C. for 15 to 30 minutes, when the coating is sintered, fully bonded and annealed. There may be a further step of heating to a subcritical annealing temperature of the steel and rapidly quenching to an age-softening temperature as described in Specification 877,793. The process may be applied to iron, steel or copper as sheet, strip wire, or articles.

[Also in Groups XXIX and XXXVII] A cam follower is turned about an axis by a cam, the turning producing movement to, and away from, the cam surface to actuate a switch or valve. A spring-loaded plunger 1 is formed as a reciprocating cam by two notches 20, 21 engaged by a substantially rectangular cam follower roller 26 having extended corners 27 and mounted for rotation about a pivot 28 on an arm 30 pivoted at 31 to operate a micro-switch 34 through member 40. The plunger 1 is moved to the left by a cam 10 having two steps 13, 14 to provide half and full travel of the plunger 1. On rotation of the cam 10 in an anti-clockwise direction, the plunger first travels half stroke at step 13; a corner 27 of the follower 26 is contacted by a step 22 to rotate the follower and move the axis 28 away from the plunger 1 to actuate the switch 34. Further movement of the cam 10 to allow the plunger 1 to engage the step 14 produces a further movement of the follower 26 to bring the axis nearer the plunger and actuate the switch 34 in the opposite sense. Continued rotation of the cam 10 results in a slow movement of the plunger 1, under the action of the spring 2, the corners of the follower trailing on the sloping sides 23 of the notches 20, 21 and no actuation of the switch taking place. In a second embodiment, Fig. 3, the follower is rotated by a cam-member 70 attached to a spring-loaded cam follower 50 engaged by a rotating cam 64. In further embodiments, the follower is actuated directly by a rotating cam having notches or projections in the periphery ; the shape of the rotating cam surface providing for actuation in both or one direction of rotation or for two or one actuations of the switch per revolution. In a further embodiment the follower is formed with multiple corners extending from the axis in a non-uniform manner to provide actuation in an integral number of cam revolutions.
