Abstract: 910,281. Regulating switches. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 23, 1958 [Jan. 3, 1958], No. 264/58. Class 38 (5). [Also in Groups XXXV and XXXVI] An interpolating device comprises a tapped voltage divider, Fig. 1, and a wiper therefor 2, 3 and a transformer 5, the secondary of which is shunted by a resistance 4 from which a second wiper 6 or 7 may derive an incremental voltage which is a variable fraction of the voltage between adjacent tappings on the main divider 1, the two dividers being energized by the same voltage. Odd and even contacts associated with the transformer are arranged in inner and outer concentric circles, with intermediate dummy contacts providing for a smooth wipe. The step-down ratio of transformer 5 is such that the potential across 180 degrees of the resistance 4 is equal to the voltage between adjacent taps. A resistance ribbon 4, Fig. 2, is wiped by brushes 21 carried on a disc 18 secured to a shaft 19, and the contacts 2, 3, mounted on a disc 12, are driven also by shaft 19 through two planetary gears 24, 25. A double choke 30 is housed within the autotransformer which is wound on a toroidal core at one end of the casing, one winding being connected to each end of the auto-transformer, and the second transformer 5 is housed at the remote end. The apparatus is said to be used to produce a feedback signal indicative of position in a servo-control system for the control of machine tools. Specifications 802,472 and 910,282 are referred to.

Title: Improvements in or relating to the valve mechanism of internal combustion engines
IPC: F01L5/10
Filed: 1933-01-06
Abstract: 392,863. Valves ; valve gear. ARBLASTER, E. F., 26, 5th Avenue, Mount Lawley, Western Australia. Jan. 6, 1933, No. 499. [Class 7 (vi).] A sleeve valve 13 is given a combined rotary and reciprocatory motion by means of long oblique teeth 15 at its lower end engaging a worm 23, the shaft of which carries a crank 22 connected by a link 21 to a thrust collar 19 on the sleeve. The longitudinal movements of the sleeve cause also a to and fro oscillation about its axis owing to the obliquity of the teeth 15, which is superposed upon the rotation caused by the rotation of the worm 23. Thus when the sleeve is moving upwards there is practically no rotational movement, whereas when it is moving downwards the rotational movement is doubled. This latter rapid rotation is used for opening the exhaust ports. There may be four ports 14 in the sleeve registering with four inlet and four exhaust ports alternating around the cylinder. The worm 23 may be replaced by a pinion on a vertical axis.

Title: Pre-set tuning mechanism
IPC: H03J5/10
Filed: 1967-01-05
Abstract: 1,144,386. Tuning mechanisms. RADIO CORPORATION OF AMERICA. 5 Jan., 1967 [21 Jan., 1966], No. 799/67. Heading H3Q. A tuner has a continuously adjustable shaft carrying a gear operated by a biased member which in turn is moved by a succession of adjustable members arranged around the periphery of a spiral cam and parallel to the axis thereof, the cam being rotatable into a number of predetermined positions by a detented rotary turret. In Fig. 3, the shaft of the tuner 10 is driven by a slide 54 through a rack and pinion 62, movement of the slide being retarded by a telescopic damper 68. The slide carries an elbow 56 which is urged by a spring 64 (or alternatively, a coiled spring attached to the slide) against the helical surface of a cam 38. The latter carries near its periphery a series of adjusting elements 42 on threaded rods, these projecting through holes in the cam to determine how far the elbow 56 is moved to the left by the spring. Each element has at its other end a pinion 46, and by rotation of the cam one of these pinions engages a similar pinion 78 on the control shaft 70 when the knob 12 is pushed in (Fig. 4, not shown). Thus rotation of the knob 12 alters the setting of the elbow 56 and effects fine tuning. When the knob is released it takes up the position shown in Fig. 3, and rotates the cam 40 through gears 80, 82 into one of twenty five positions set by a detent mechanism 26 (Fig. 2, not shown). Twenty four of the positions have elements 42 and the last is occupied by the transition 39 from one extreme setting to the other, for which purpose movement of the elbow 56 is damped by the pneumatic dashpot 68. The channel to which the tuner is set (e.g. in the U.H.F. band) is shown on a translucent drum 20 visible through a window 22 as in Specification 1,095,403. The drum is rotated by a gear 88 through an intermediate gear (84 in Fig. 2, not shown) from the gear 82. Three consecutive numbers are visible through the window at any one time (Fig. 1, not shown) and the setting of the corresponding element 42 determines to which of these channels the set is tuned. Motor control.-The tuner can if desired be operated remotely by programmed control of a motor. The latter (not shown) drives through a gear train 96 a gear 98 which bears a pin 100 engaging a star-wheel 94 on the shaft of the cam 40. The latter is therefore rotated to the next position for each revolution of the gear 98. To prevent the motor from stopping at an unused detent position, the element 42 at such a position is screwed fully to the left where its opposite end engages a leaf-spring switch contact (104 in Fig. 2, not shown) to deflect it into engagement with a screw 102 to keep the motor energized. A similar stud (105) is mounted at the transition position 39.
