Title: Improvements in or relating to cylinder locks
IPC: E05B29/00
Filed: 1959-02-20
Abstract: 883,116. Barrel locks. SMOGAR, F. Feb. 20, 1959, No. 5986/59. Class 44. In a cylinder lock, grooves 2 are provided on the inner surface of a housing 1 and corresponding grooves 4 in the outer surface of an inner cylinder 3 for receiving locking rings, so that the locking rings assume a non-circular peripheral shape when located in the double grooves so formed, the locking rings being converted to a circular peripheral form by serrated key bits 20 of an inserted key 18 by means of intermediate pins 17 to become located wholly in the grooves of the inner cylinder to form a smooth surface therewith, whereby firstly axial shifting of the inner cylinder and then after release of a locking device 13, 14 by such axial shifting, rotation of the inner cylinder and a locking member 11 connected thereto for releasing the lock by the key, becomes possible. The locking rings each consist of circular segments 5 connected to one another by joints 6 and a spring 7, Fig. 2, the ring assuming an oval form under the action of the spring to prevent axial movement of the cylinder 3 relative to the housing 1. The cylinder 3 has a spigot 8 extending through the housing 1 carrying a sleeve 10 locked to it by a pin 9, the sleeve 10 in turn carrying the locking member 11. A helical spring 12 urges the cylinder 3 towards the key aperture so that the sleeve 10 and locking member 11 abut the end face of the housing 1 with the grooves 2 and 3 coinciding. In this position rotation of the cylinder 3 is prevented by the locking device which consists of a tooth 13 firmly fixed to the end face of the housing and a groove 14 in the sleeve 10 which is engaged by the tooth. The pins 17 are located in radial apertures 16 in the cylinder 3 and bear on the inside surface of the locking rings. The locking rings can each be a band of steel strip or wire.

Title: Improvements relating to ultra high frequency heating
IPC: H05B6/70
Filed: 1949-03-09
Abstract: 664,926. Dielectric heating. BRITISH THOMSON-HOUSTON CO., Ltd., and KEITLEY, R. March 9, 1950 [March 9, 1949], No. 6433/49. Class 39(iii) Apparatus for subjecting a dielectric load to heat by means of U.H.F. oscillations comprises means for establishing in the material at least two plane polarized electric waves of the same frequency, the planes making an angle, preferably 90 degrees, to one another. Material 2, Fig. 1, is placed within a region 3 connected to rectangular wave guide sections 4, 7 whose transverse axes are arranged at 45 degrees with the main axis of the region 3 and parallel or at right angles to each other. Section 7 is closed by a plug 9 and fed by a section 10 with a plane polarized wave which heats the load. The unabsorbed energy is reflected from a plug 6 in the section 4 to the load and the unabsorbed energy again reflected from the plug 9 to the load. The taper sections 5, 8 shift one plane polarized wave relative to the other by a quarter wavelength in each passage. A dielectric sheet 11 parallel to one of the wave planes changes the relative phase velocity and may, together with adjustment of the plugs 6 and 9, effect resonance within the chamber for both waves. Fig. 3 shows an arrangement which does not require conversion from circular to plane polarized waves. The remote end of the heating chamber fed from wave guides 10, 7, contains reflectors 12, 13, the former reflecting back to the load a wave of one mode, and the latter reflecting back waves of all modes. The distance between the reflectors is so arranged that waves having the two planes of polarization and displaced by a quarter wavelength are established in the load. Alternatively, Fig. 6, adjustable polarizing screens 19, 20 are arranged at each end of the heating chamber, energy being fed from wave guides 17, 18. An electromagnetic horn section 21, Fig. 7, projects a beam of circularly polarized waves on to a load 2, with reflecting screens 22, 23 spaced approximately one quarter wavelength apart and which reflect one or other of the plane component waves. Specifications 605,655 and 616,996 are referred to.
