Title: Improvements relating to tuning arrangements for radio and like receivers
Inventor: O'DELL ALBERT GEORGE
IPC: H03J3/10
Filed: 1949-09-07
Abstract: 677,143. Radio receiving apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 7, 1950 [Sept. 7, 1949], No. 23134/49. Class 40 (v). A radio receiver having both coarse and fine-tuning is provided with visual or audible means to indicate when the coarse-tuning means is suitably adjusted for fine tuning to be effected. In coarse tuning, the tuning control 2 drives a variable condenser 10 via a friction coupling 3, 4 cord drive 7 and pulley 8, a pointer 12 being also driven by the cord 7. To the shaft 9 of the condenser is attached a drum 14 carrying pre-set condensers 15, each corresponding to a band-spread tuning range and being connected to a corresponding insulated contact 16 fixed to the periphery of the drum. During coarse tuning the contacts 16 successively engage a fixed contact 17 which is coupled by a pin to a further pair of contacts 18, 19 and is so shaped that in tuning positions corresponding to the centres of band-spread ranges contacts 18, 19 are closed and light an indicator lamp 20. Band-spread tuning may then be effected upon depression of the knob 2, which causes operation of a switch 21 via collar- and-pin mechanism 38; interlocking comprising a recessed disc 36 attached to the shaft 32 and a detent 39 fixed to the shaft of the wave-range switch 35 prevents band-spread operation other than on the short-wave band, or rotation of the wave-change switch when band-spread operation is in force. Switch 21, in the band-spread position, disconnects the oscillator section of condenser 10, substituting the preset condenser 15 preselected by contacts 16, 17, and a variable inductance 30 having a magnetic core 29 which is coupled to the knob 2. The drive comprises friction coupling 3, 22, cord drive 24 and pulley 25 which is free to turn on shaft 9 and carries an attached pulley 26 coupled by a cord 27 to the core 29. A pointer 31 is attached to the cord 24.

Abstract: 734,691. Piston and stuffing-box packing. WALES-STRIPPIT CORPORATION. Sept. 22, 1952 [July 10, 1952], No. 23686/52. Classes 122 (1) and 122 (5). [Also in Group XXXII] Packing for a piston 24, or a stuffing-box 130, comprises a sleeve 35 with a circular, V-shaped groove 37 in one of its ends and a resilient ring 36 seating in the groove, the groove having walls 38, 39 of different lengths of which the wall 39 adjacent the cylinder, when the piston carries the packing, is the longest and forms a flexible lip 45 adapted to be pressed against the cylinder by the ring, and the latter being thick enough to extend from the groove and press against the wall of the piston. As applied to packing the piston 24 of a liquid-spring 20, the sleeve 35, which may be made from a plastic such as a bearing nylon or one of the high-strength vinyls, is retained on a reduced shank 26 of the piston by a cap 27 provided with screw-threads to engage the shank. The sleeve may be formed with a wall of constant thickness or one that tapers away from the ring 36 or has a shoulder 42. Upon the piston being displaced and compresing the silicone-base liquid in the cylinder, the liquid, passing the cap 27, Fig. 3, forces the ring, which may be made of soft rubber, into the groove 37, Fig. 4. At liquid pressure approaching 20,000 1b./square inch the sleeve 35 may be compressed sufficiently for it to thicken into engagement with the piston and the cylinder, closing gaps 65, 66. A sleeve 130, Fig. 6, is formed with a lip 145 on the inside for packing the stuffing-box 130, the lip being pressed against a piston 101 by a resilient ring (not shown). The relative proportions of the length, diameter and thickness of the sleeve are stated and compared with the length of the wall 39.
