IPC: F16B7/02
Filed: 1920-07-03
Abstract: 167,064. Wearden, L., and Guylee, F. July 3, 1920. Chucks.-A fastening for securing one hollow cylindrical body inside another, which is especially applicable for securing the cone D in the body C of a chuck of the type described in Specification 11267/10, consists of a split ring R engaging a shallow groove in the body C and bevelled internally to engage a bevelled recess in the cone D. The ring R projects beyond the upper surface of the cone D, and, by means of pressure by a tool T on the upper ball race, the ring R can be cammed over the lower edge of the groove in the body C, whereas a pull on the cone D expands the ring into the groove.

Title: Improvements in and relating to electric incandescent lamps
IPC: H01K1/16
Filed: 1948-07-09
Abstract: 638,805. Electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. July 9, 1948, No. 18548. Convention date, July 12, 1947. [Class 39 (ii)] In an electric lamp, particularly of the high wattage type, the leading-in conductors to the two ends of the filament 11 each comprise a spud or inserted plug portion 26 of metal such as molybdenum or tungsten over which a helical compression coil 31 and the coiled end portion 30 of the filament are fitted, these two coils being screwed together throughout a portion only of the length of the compression coil and compressed between opposed shoulders 27, 29 provided on the spud. The shoulder 27 is formed by flattening the end 28 of the spud, and shoulder 29 may be provided by a clip or lug 25 the ends of which are pinched tightly around the spud 26 and a supporting conductor 10. Alternatively, the upper end of the conductor 10 may be bent inwardly at right-angles and the upper end of the spud welded thereto, or a flat plate may be welded across the upper ends of the members 10 and 26. In forming the joint with the filament the compression coil 31 and filament end coil 30 are first screwed together for an overall length less than the designed distance between the shoulders 27, 29, and the unflattened end of the spud is then inserted through the inter-threaded coils and either clamped in the lug 25, or welded in the manner stated, after which the two coils 30, 31 are partially unscrewed until their respective outer ends abut against the shoulders 27, 29. This contact between the shoulders and the ends of the coils short circuits the filament end-coil 30 and ensures a uniform effective length of filament.

At the end of the message the tape recorder motor is switched-off either by means of conducting areas on the tape co-operating with switch members (similar to the above arrangement) or by means of a time-switch device. Instead of utilizing Doppler radar signals the map drive may be provided by the output selected by switch 33 of an M-type transmitter 34 driven by a constant speed motor 26 and the speed of such movement set by a manually-operated variable speed-control device 31. Also, by operation of a switch 24 (details of which are described with reference to Fig. 3, not shown) the output of a further M-type transmitter 28 may be employed for operation of the index 9. To enable maps having different scales to be employed, threespeed gear-boxes 22 and 36 controlled by a selector device 41 are utilized in the index and map drives respectively. Initial setting of the index 9 may be effected by means of a manual control 12. The map is illuminated by means of an A.C. energized electroluminescent panel 3.
