Abstract: 960,541. Nailing machines. PLYMOUTH CORDAGE INDUSTRIES Inc. Sept. 29, 1962, No. 37009/62. Heading B4C. A pneumatically actuated tacker comprises a piston 11 mounted in a cylinder 10 and having a driver 12 co-operable with a tack holding device 20, a main valve 26 for controlling the flow of compressed air from an accumulator 28 and a secondary valve for controlling the supply of air to a tack magazine 45, the arrangement being such that as the tack driver is brought into action, the secondary valve is caused to allow pressure fluid to be supplied to the magazine for automatically feeding tacks therefrom towards the holding device in order to provide tacks for succeeding driving operations. The piston 11 is retained in its inoperative position by a spring 33 and, in this position, is arranged to abut the end of the secondary valve member 39 in order to maintain the latter in a closed position wherein communication between the accumulator and the magazine, via a passage 40, is cut off. The secondary valve 26 is normally maintained closed by a spring 27 and opened via a rod 25 connected by a link 22 to a slidable nozzle 19. The magazine is in the form of a transparent glass tube 45 surrounded by a perforated sleeve, the sleeve being clamped to the housing 30 of the tacker. A race-way 47 for the tacks extends into the magazine and also the housing, the lower end of the race-way being adjacent a delivery tube 16 leading to the holding device 20. A piston-actuated clearer slide for correctly positioning the tacks in the race-way is provided. In order to permit only one tack at a time from reaching the holder a separating device is mounted in the housing which comprises a rod 58 attached to a piston and normally urged by a spring to prevent the lowermost tack from dropping to the holder; upon actuation of the tacker the piston is moved so as to release the lower tack and allow a plunger 60 to stop movement of the next tack. In operation, the nozzle 19 is pressed against a workpiece thereby opening the main valve so that compressed air from the accumulator actuates the piston, the latter then allowing the secondary valve to open. Air passes, via the passage 40, to the magazine at a reduced pressure governed by a valve 62, the air agitating the tacks so that some fall into the race-way and also actuating the separating end clearing devices. A clamping device 82 adapted to prevent too many tacks from resting on the separating spindle 58 is located in the raceway and a diaphragm -actuated plunger 76 is arranged to press the lowermost tack in the race-way into the top of the delivery tube 16.

Abstract: 883,832. Testing cable insulation. OKONITE CO. Nov. 20, 1958 [Dec. 17, 1957], No. 37358/58. Class 37. In apparatus for the corona testing of insulation in which corona discharge is induced in voids in the insulation, a first detector detects both the presence of corona and extraneous noise disturbances and a second detector is responsive only to the extraneous disturbances the outputs of the two detectors being combined so that the effects due to the unwanted noise is balanced up. Fig. 1 shows an apparatus for the corona testing of an electric cable insulation, the cable being wound on a drum 12 and immersed in an earthed tank 10 filled with a poorly-conducting liquid such as distilled water, the cable insulation being stressed by connecting the centre conductor to the secondary of a high-voltage transformer 16 the other side of the secondary being earthed. The presence of corona discharge due to faults in the insulation is detected by the radio-frequency detector and amplifier 22. A second amplifier 30 is fed both with any noise signals which may be induced in the power supply to the transformer 16 and picked up on an aerial 28 due to ratio-frequency emanations from unwanted sources. The antenna aerial 28 is located sufficiently far away from the source of corona discharge in the insulation voids as to be unaffected by them. The output of the two amplifiers are applied to phase inverter and balancing circuits 32 so that any inputs due to noise on the power supply or present in the surroundings of the test apparatus are balanced out and only the corona discharge due to voids in the insulation tested are displayed on cathoderay tube display 34. In a modification shown in Fig. 2, the cable is drawn off a drum 36 on to drum 44 via a tank having two earthed end portions 38, 42 and a centre-portion of insulating material at the centre of which is a conducting electrode connected to the secondary of high voltage transformer 16 the other side of which and the centre conductor of the cable under test being earthed. Thus, as the cable progresses through the tank it is progressively subjected to increasing electric stress the presence of voids and the removal of unwanted noise disturbances being detected and balanced out respectively by amplifiers 22, 30, phase inverter and balancing control 32 as described in connection with Fig. 1.
