Filed: 1952-07-21
Abstract: 709,467. Testing strength of pipes. MANNESMANN AKT.-GES. July 21, 1952 [July 21, 1951; July 21, 1951], No. 18423/52. Class 106 (2) Apparatus for testing tubes 6 by internal pressure of the type comprising two testing heads sealing the tube ends and adapted to be adjusted in relation to one another lengthwise of the position of the tube under test, one of the heads 6, containing the filling and pressure water inlet of the apparatus and being movable lengthwise of the position in a fixed bearing 2, while the other is disposed on a carriage 4 adapted to be adjusted lengthwise of the position to accommodate the length of the tube to be tested, and then to be held fast in its adjusted position, is characterized in that the testing head 3 which is within the fixed bearing 2, is combined therein with one or more piston surfaces which are exposed to the action of the pressure water and are effective to support the head against the testing pressure obtaining in the tube in the testing position, the latter being defined by abutments. The tube 6 to be tested is introduced into the testing head 3 by means of a carriage 4, the testing head embracing the tube in fluidtight manner by means of a packing ring 27. The testing head 3 is guided for sliding movement with a piston 28 in the fixed bearing 2. The piston 28 contains the filling and pressure water inlet 29 which connects the interior space 30 of the bearing. A controllable pipe 31 for the supply and discharge of the filling and pressure water leads into the interior 30. The piston 28 extends rearwardly by a rod 32 which projects out of -the bearing 2, and to which two auxiliary pistons 35 are connected by a crosshead 33 and a piston rod' 34. 'Each of-these auxiliary pistons is guided in a cylindrical cavity 36 in the bearing 2. By the introduction of filling and pressure water into the cavities 36 through the pipes 37, the testing head 3 is drawn in the forward direction into the operative position shown in the Figure. The testing pressure in the tube acts on the testing head with a force corresponding to the cross-section of the tube to force it back. The testing head is supported against this face by the pressure acting on the auxiliary pistons 35. After testing the testing head is released and pushed back sufficiently to enable the tube to roll away from its position between the testing heads in a transverse direction.

IPC: H02P7/298
Filed: 1966-04-27
Abstract: 1,136,258. Automatic speed and current control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 25, 1967 [April 27, 1966], No. 18443/66. Heading G3R. [Also in Division H2] The armature 10 of a D. C. motor is supplied from semi-conductor network 11 associated with amplifier 12 receiving reference and currentresponsive signals. The field winding is energized from semi-conductor network 14 controlled by amplifier 15 receiving reference and speed-responsive signals, the amplifiers 12, 15, being inter-connected through a spill-over circuit 17. If the speed reference voltage is changed, an error signal is derived from amplifier 15 to alter the field current in a corrective sense. When the error signal is of sufficient magnitude to pass through circuit 17 it modifies the reference signal applied to the amplifier 12. Thus, if an increase in speed is required, both the field and armature currents are increased until the new speed-level is reached, whilst a demand for speed-reduction leads to a reduction in both fields and armature currents. A feedback signal from the fieldcurrent is also applied to the amplifier 15.

Abstract: 402,873. Crimping paper sheets. HARBORNE, T. L., Torwood, The Shrubbery, Weston-super-Mare. July 1, 1932, No. 18587. [Class 141.] In a machine for fixing together superposed sheets of paper or the like by passing them between a pair of serrated or knurled wheels which crimp the plies together as they are fed over an associated table, means are provided to adjust the pressure between the crimping wheels and separate means to bring about a quick release or disengagement thereof without moving the pressure-adjusting means, whereby the crimping may commence or cease at any desired part of the sheets, packages or the like. The crimping wheels 1, 2 are mounted in a frame 5 and the shaft 3 of the wheel 2 is driven by power or manually by the handle 4. The spindle 10, carrying the wheel 1, is pivoted at 11 and the wheel 1 is adapted to be resiliently pressed against the wheel 2 by a block 13, which bears on the spindle 10 and is eccentrically mounted in a pair of plates 12. The plates 12 are adjustably pressed downwards by rotating a knurled nut 14, which carries a spindle 15 threaded in a block 16 secured between the plates. A rubber bush 18 and a spring 17 serve to render resilient the mounting of the wheel 1, and the pressure can be instantaneously released by partially rotating the eccentric block 13 by means of external hand lever secured to one of the block trunnions. The pressure is re-applied when the hand lever is restored to its original position. The lower wheel 2 may be adjustable and the block 13 may be replaced by a cam &c. A guide plate for the sheets as they are fed to the wheels is adjustably mounted on the table 6, and comprises a pair of rigid channels 20 united by an inserted rubber block 22. A pair of hooks, slidable along opposite edges of the table, are joined by a spring band, the tension of which may be adjusted, and the hooks are attached to the ends of the channels 20, whereby the position of the guide plate as a whole may be adjusted to any requisite position relatively to the wheels 1 and 2, and clamped in such position. The guide plate may be fixed on the table 6 and the latter or the wheels may be moved to effect the same relative adjustment.
