Title: Riveting machines
IPC: B21J15/04
Filed: 1930-04-07
Abstract: 348,819. Riveting-machines. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., SIR W. G., WYLIE, H. N., and CRABBE, P. G., Park Side, Coventry. April 7, 1930, No. 10981. [Class 43.] In machines for fixing a tubular rivet by drawing a mandrel into it, an actuating lever 7 is provided, on rotation of which in one direction, the mandrel is first clamped between an outer strap element 11 with a block 12 and a centre link element 13, and is then drawn substantially axially. The lever 7 is hinged at 8 to a vertical channel frame member 9 mounted on the machine, and is rotated by lever- and-link mechanism from an operating pedal. The centre element 13 is pivoted at 19 to a bottom link element 20 pivotally mounted at its lower end 21 on the frame member 9. The bottom element 20 has an offset portion which is pivotally connected at 22, 23, by a link '24 to the outer element 11. The element 11 carries a roller 25 engaging a curved cam surface 26 of the centre element 13, and is connected by a link 28 to the lever 7. In operation, rotation of the lever, owing to a pin-and-slot connection 15, 16, between the centre and outer elements 13, 11, causes the element 11 first to clamp the mandrel firmly, whereafter the linkage mechanism as a whole is rotated about the fixed centre 21 so as to draw the mandrel substantially axially. A strap 30 may be provided so as to limit rotation of the mechanism, and it may be fitted with an adjustment for limiting movement of the mandrel. The centre and bottom elements may be formed integrally, or the outer and bottom elements may be directly pivoted without the interposition of the link 24. Specification 286,471, [Class 43, Fastenings, Dress], is referred to.

Title: Improvements in or relating to suction heads for pneumatic pick-up devices
IPC: B65H3/08
Filed: 1966-03-14
Abstract: 1,097,996. Feeding sheets. SIEMENS AG. March 14, 1966 [March 15, 1965], No. 11010/66. Heading B6B. A pneumatic head for separating sheets &c. sequentially from the top of a stack comprises a suction tube 8 which supports a perforated suction plate 1 connected pivotally at 6, 7 to slidable rigid side plates 2, 3, respectively, a bellows 9 connecting the plate 1 to the suction tube 8, and a pneumatic brake means 4 for braking upward movement of the plate 2. Thus, when the plate 1 engages, and is sealed by, the top sheet of the stack, the bellows 9 will commence to collapse due to the build-up of suction, the brake 4 will prevent upward movement of the plate 2, and the plate 3 will be forced upwardly, causing the plate 1 to be tilted about the pivot 6. The grasped sheet will be tilted away from the top of the stack and deformed against a stop 5 carried by the tube 8: this will ensure that if a second sheet is raised with the top sheet, the second sheet will fall back on to the stack. The brake means 4 comprises a bellows 10 in communication with the tube 8, and an outer wall 11 which can press a pin 12 against the side plate 2. When the pneumatic head and tube 8 are moved upwardly, a cam device releases the brake 4, so that the plate 1 and separated sheet are restored to horizontal position, swinging about the pivot 7. The sheet is then swung outwards and transferred to feed rollers &c.

Abstract: 1431736 Electron spectrometers; electron microscopes NIHON DENSHI KK 12 March 1974 [12 March 1973] 11063/74 Heading H1D [Also in Division H4] In an apparatus in which a specimen 3 is bombarded with a scanned or static primary electron beam 4 and the secondary electrons are analysed in an electrostatic parallel plate energy analyser 5a, 5b, noise adjacent a peak in the secondary electron spectrum is reduced by providing a system which measures the intensity of the spectrum on one or both sides of the peak and subtracts an electrical signal representing that intensity from one representing the peak value. In Fig. 6 the voltage across the the separator is scanned by means of two power supplies 11, 12 added at 10. The output of the analyser is measured by a detector 9 and a signal amplified at 17 is directed by one of gates 18, 19 to a respective integrator 20 or 21 depending on whether the peak value or adjacent values are being passed by the analyser at the time. The outputs of the integrators are subtracted at 22. The output in Fig. 6 is displayed on a cathode-ray tube 32 which is synchronized with primary electron beam 4. Figs. 1, 4 and 7 (not shown) illustrate embodiments with a static primary electron beam in which case the output is measured rather than displayed. In Fig. 4 the integrators and subtractor are replaced by a reversible counter (24). In Figs. 7, 9, 11 (not shown) discrete detectors spatially separated replace the scanning of the energy analyser, respective detectors being allotted to adjacent ranges in the spectrum thus eliminating the need for a timed sequential operation.

Abstract: 844,337. Electromagnets. AFO APPARATENFABRIEK " OVERIJSSEL " N.V. April 9, 1958 [April 9, 1957], No. 11324/58. Class 35. In an electromagnet of the kind in which, upon energization of the coil, an armature or core is pulled into the field of the coil, the core is blocked in both the unattracted and the attracted positions by a locking member of magnetic material which is spring-actuated in the unattracted position of the core and actuated by the magnetic field in the attracted position. The core 1 may carry a bracket 7 and be locked in the unattracted position by pins 4 projecting into holes in bracket 7 and held there by springs 5. Excitation of coil 3 produces flux leaking through the pins 4 which are thereby inwardly attracted to free the bracket and hence the core 1 which is then drawn into the coil and blocked in that position at the end of its stroke by the pins 4 pressing against the reduced portion of core to engage behind the shoulder formed thereby (Fig. 2, not shown). An alternative arrangement using two hooked arms which engage with projections on the magnet casing is described (Figs. 3 and 4, not shown).
