Abstract: 665,032. Fluid-pressure servomotor-control systems. RUHRCHEMIE AKT.-GES. July 20, 1949 [Aug. 20, 1948], No. 19108/49. Class 135 [Also in Group XIII] In a process for drying or cooling granular material, the material passes inside a container, over an intermediate floor through which gases flow and thence through a discharge opening of variable aperture, the width of this aperture being so controlled through a servomotor system that the layer depth of the material remains constant on the intermediate floor. The apparatus shown consists basically of a container 1 having an intermediate perforated floor 2 and a pipe 6 to admit the drying or cooling gases. The material enters the container through an opening 3 and is discharged through an opening 4 whose diameter is varied by a flap valve 5. Either the weight of the material on the floor 2 or the back pressure produced by the material at a given feed weight is used to control the valve 5 through a servomotor system. As shown in Fig. 4 the gas pressure prevailing under the floor 2 acts on a membrane 18, the back of which is maintained by a spring 19 whose tension is preadjusted according to the desired depth of material. The movement of membrane 18 actuates a throttle valve 11 which from a pipe 12 releases compressed air on to a further membrane 14 which operates, against a spring 13, the valve 5. In a modification the floor 2 is pivoted at one end, supported by a spring at the other end and a connecting link operates the throttle valve 11, the action then being as above. In another modification shown in Fig. 8 .there is secured in the lower part of the container a spring- loaded membrane 21 which is displaced by the weight of the material and acts on a throttle valve 11, the system then being as above described.

Filed: 1936-07-13
Abstract: 480,248. Impulse transmitters. SEGEAL, B. July 13, 1936, No. 19477. [Class 40 (iv)] A dialling finger comprising a plunger carried by a rotary arm and adapted to be engaged with the finger holes is controlled by a handle having a limited sliding movement on the plunger. As shown in the Figure, the plunger i carries a cap k on which is mounted the handle m so that when the handle is depressed it engages flange n on the cap which forces the plunger downwards against the action of a spring l mounted between the upper end of the cap and a bearing h on the rotary arm g. When the handle is pulled upwardly, limited sliding movement between the handle and the cap takes place against the action of spring p arranged between the handle and cap. In modifications, the spring l resisting downward movement of the plunger is omitted, the plunger being rigidly fixed to a resilient rotary arm and being controlled by a handle normally resting on the arm but capable of upward movement on the plunger freely or against spring action. Arrangements for detachably mounting the rotary arm on the dial are similar to those described in Specification 453,826.

Abstract: 1,220,112. Retractive switches; snap-action switches. PAINTON & CO. Ltd. 17 April, 1969 [24 April, 1968], No. 19502/68. Heading H1N. A key switch includes a pivoted lever 2 urged to one or more stable positions by a resilient tongue 13 on the switch body 1 having a pip 14 engaging one of the differently shaped cam surfaces 24, 25, on a cam member 23 on the lever 2. The cam member 23 may be integral with lever 2 and the switching characteristic is then changeable by removing the lever 2 from the switch body 1 and rotating it through 180 degrees before re-assembling it to the body. Cam surface 24 causes biasing of lever 2 towards either one of two stable positions, while cam surface 25 causes biasing of lever 2 to a centre position, Fig. 4 (not shown). Other cam surfaces with three or four inclined planes can provide for three position switches with two or three stable positions, Figs. 6, 6A, 7, 7A (not shown). The cam member 23 may be detachably secured to the lever 2 to enable such different configurations to be substituted, Figs. 8, 9 (not shown).

Title: Improvements in or connected with rangefinders, heightfinders and other optical observation instruments
IPC: G02B23/16
Filed: 1943-11-23
Abstract: 580,645. Seats for rangefinders. BARR & STROUD, Ltd., STRANG, J. M., and FOSTER, C. Nov. 23, 1943, No. 19551. [Class 52 (ii)] [Also in Group XXIV] An observer's seat is adjustable downwards under his weight subject to control by and in accordance with the movement of the eye-piece of the rangefinder as the latter is turned to increase the elevation of the angle of sight, the movement of the seat being thus effected without the use of external power. The base 7 of the seat S is supported on a pair of levers 4 pivoted on the base brackets 2, and is partly controlled by a pair of parallel radius rods 5 pivoted at 6 on the brackets ,2. A coil spring 8 is secured at 3 between the levers 4 and its lower end is anchored to the base brackets 2, the spring tending to urge the seat upwards. The seat supporting levers 4 are coupled to a transverse oil reservoir 11 beneath which is an oil cylinder 9 mounted in trunnions 10 between the base brackets 2. When the rangefinder gear is operated so that the eye-piece is lowered, a flexible shaft 13 from this drive operates a worm drive 17-18, autolock free wheel 19, and spindle 15, (see Group XXIV). Thereby a cam 16 is turned to depress rod 23 which opens valve 22 to allow oil to escape through 21 to the top of the hollow piston 20 and to a reservoir 11. The seat therefore sinks under the observer's weight and the reservoir 11, moves angularly relative to the links 4 and therefore relative to a gear box 14 which turns the cam 16 so allowing valve 22 to close and thus holding the seat in the desired lower position. Further depression of the eye-piece gives a further depression of the seat. To elevate the seat the observer takes his weight off the seat whereupon the spring 8 turns the links 4 and radius rods clockwise in Fig. 1. Valve 22 leaves its seat and allows oil to pass from above to below the piston 20. The seat continues to rise as far as the observer desires it. For hand adjustment, a knob 25 is turned to operate through the free wheel autolock 19 so turning the cam 16 to allow the seat to lower independently, and also allows initial setting of the cam 16. To render inoperative the control of the seat from the rangefinder gear, a lever 26 pivoted at 27 is moved by hand to slide the spindle 15 and its cam 16 endwise, so rendering the cam inoperative and so fixing the seat position. A key and keyway in the gear box 14 allows this sliding motion. In a modification of the hand control, Fig. 6, hand rotation of the head 31 moves a stud 34 in a helical groove coupled to the spindle 15 which thereby is moved axially and puts its cam 35 out of gear. The whole arrangement is mounted on a turntable base.
