Title: Improvements in abrasive wheels
IPC: B24D5/06
Filed: 1927-09-01
Abstract: 277,013. Triggs, W. W., (Norton Co.). Sept. 1, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 5, 1927]. Wheels.-An abrasive wheel is constructed of segments 10 united by a filler, for example, Babbitt metal, poured whilst hot into the spaces between the segments. A reinforcing structure also may be employed, formed from the metal and having rings 17, 18 on each side of the wheel united to the transverse filling 19. The segments may have lateral projections 12 against which the rings 17, 18 abut closely, the outer rings being bevelled and forming shoes adapted to be engaged by corresponding faces on clamping- plates 30, 33, which secure the wheel on a shaft 25. The plate 30 abuts against a collar 26 on the shaft and the plates are held in position by a nut 35, a bushing 27 being interposed between the abrasive ring and the shaft. Steel &c. wires may be embedded in the rings 17, 18, and the. projections 12 may have indentations to hold the rings. The metal fillers 19 may extend only to the rings 18, the spaces outwardly of the rings being filled with a mixture of graphite and sulphur; the filler between operative portions of the segments is such as to wear away at substantially the same rate as the segments. Specification 238,176 is referred to.

Abstract: 943,152. Dispensing circlips. ANDERTON SPRINGS Ltd. June 26, 1962 [June 26, 1961], No. 22999/61. Heading B8S. In a circlip dispenser of the kind in which a stack rod 2 carrying the circlips 3 has a lower end portion 4 whose width is reduced to allow for the withdrawal of only the bottom clip, this end portion fits into a hole 5 in the base 1 of the apparatus and abuts the bottom of the hole. The hole is bounded on one side by a plug 6 with an upstanding boss 8 and on the other by an L-shaped block 7 whose upstanding limb forms a guide for the circlips. The bottom of the hole 5 is defined by the horizontal limb 5a of the block 7 and the top of the hole by the upper surface of the plug 8. The screw-adjusted collar 10 is used to set the depth of the hole so that the clearance between the top thereof and the step 4b, Fig. 2, in the stack rod slightly exceeds the thickness of one circlip. The screw shank 9 may be extended upwardly to provide a holding bracket 12, Fig. 1 (not shown), for the upper end of the stack rod. The base 1 may incorporate a guide for an applicator tool which removes the bottom clip. A plurality of the dispensers may be mounted on a common base 1.

The magnetic core structure of a coil assembly is provided by depositing magnetic material on to the coil. As shown Fig. 2 the coil comprises "printed" conductors 1, 2 in the form of spirals surrounding an aperture 4 in an insulating substrate 3 which is also provided with slots (6) arranged round the outside of the coil. The conductors are covered with a layer of insulating material and a layer 5 of magnetic material is electrodeposited over the conductors so that it completely surrounds the coil at the positions where the slots (6) are provided. The layer of magnetic material may be provided with a circumferential gap 7 and radial gaps (8) to reduce polarizing effects and eddy current losses. The layer 5 is oxidized and a second layer 9 of magnetic material is deposited, the gaps in this layer being displaced relative to those in. layer 5. The magnetic material may be a ferromagnetic alloy containing Co, Fe, Mo or Ni. A current may be passed through the coil during the deposition of the magnetic material to provide a coil with a preferred direction of magnetization.

Abstract: 169,365. Sloan, Ltd., L. G., and Aston, A. Aug. 12, 1920. Moving-apparatus.-A device for demonstrating the action of lever-type self-filling fountain pens, such as described in Specification 5790/15, [Class 146 (iii), Writing-instruments &c.], comprises a disc b on which the pen a is mounted and with which it oscillates vertically so as alternately to dip the pen-nib into ink in a pot d and to raise it therefrom, the lever w of the pen being moved into the closed position to fill the pen, while the nib is immersed in the ink, and turned outwardly while the pen is raised, so expelling the ink. The mechanism comprises a continuously rotating cam t which bears on a roller u mounted on a cross-bar g to which, and to another cross-bar h, a bearing-plate, the pen a, and the disc b are fixed. The bars g, h slide on guides j, to one of which is fixed the bearing for the shaft o of the cam t. The pen lever w is connected by a rod x to a lever y, z, which is turned by a roller 16 on the cam t through about a right-angle till the rod x snaps under and is held by the hook 17 of a lever 18, both levers y, z and 18 being mounted on the bearing-plate. and the pivot of the lever y, z being coaxial with that of the lever w. The roller 16 after leaving the lever y, z comes against a pin 22 on the lever 18 which is thus turned against the action of a spring 20 to release the rod x from the hook 17 and allow it to fly back, to close the lever w, under the action of a spring 12. The curvature of the cam t is such that the pen a rests awhile at the top and bottom positions, and the parts are arranged so that the opening of the pen lever w takes place while the pen is at the top position and its closing while the pen is at the bottom position.

Abstract: 1381915 Handling film spools AGFAGEVAERTAG 19 May 1972 [19 May 1971] 23799/72 Heading G2X The leading end of a strip of backing paper is separated from the leading end of a film strip by an apparatus which then feeds the film alone into a guide channel. The apparatus is used in connection with the joining of several film strips into a long continuous strip for passing through a developing machine. As shown, the spool 1, in which the film is backed by a paper strip overlapping the film at each end, has been extracted from a cassette and is suitably supported in a mounting in which it can be rotated by a friction roller 6. Initially the spool is rotated in the direction of the arrow 32, Fig. 3, (i.e. opposite to the unwinding direction). The end of the paper leader 2 is lifted away from the rest of the roll by air blown through a nozzle 28, and drawn against a suction nozzle 29. An amplifier 30 and switching means 31 now switches the driving motor off. As shown in Fig. 2, two flaps 9 and 10 are pivoted on a pin 13. Both flaps are spring-urged to press against the film roll Fig. 1 (not shown). As spool 1 rotates anti-clockwise, the front end of the paper leader 2 is guided downwards by the end of flap 9. It is further guided downwards by a wall 19 into a space where it interrupts a beam of radiation to a photo-electric receiver 22, Fig. 1 (not shown). This causes a rotary magnet 11, and hence a lever (14) which it carries, to pivot clockwise from the Fig. 1 (not shown), position to the Fig. 2 position, so pivoting flap 9 out of the film path. The leading end of the film itself is now stripped away from the roll by the flap 10 and guided into a channel 18, whence it may be led to a splicing device.
