Abstract: The invention provides a detector for detecting air components, e.g. contaminations, and in particular noxious or poisonous contaminations, which device comprises a housing in which an air pervious carrier containing a first reagent is arranged, this detector being adapted to draw air to be tested through said carrier so as to expose this reagent to the air, this reagent being influenced by the components to be detected, which carrier is to be contacted with a second reagent which, together with the first one, can bring about a colour reaction depending on the fact whether the first reagent has been influenced or not. The housing forms, in the operative condition, an integral unit, an air- and liquid-tight container with a rupturable wall and containing a not contaminated liquid contributing to said colour reaction being arranged within said housing, the latter being, furthermore, provided with a yieldable wall portion and a plurality of piercing pins arranged in such a mutual spatial relationship that the container can be pierced by pressing inwards said wall portion, so as to moisten said reagent carrier with the liquid from said container. In particular the second reagent can be contained in a similar second carrier which is normally separated from the first one but is contacted therewith when pressing inwards said wall portion.

IPC: B21C37/22
Filed: 1958-01-07
Abstract: 847,692. Machine-tool details. BIRWELCO Ltd. Jan. 2. 1959 [Jan. 7, 1958], No. 572/58. Classes 83 (3) and 83 (4). Apparatus for performing repetitive operations on a cylindrical workpiece automatically, e.g. drilling holes or welding studs on the work periphery, in which the work is moved about its longitudinal axis and also fed axially, comprises a base 5, Fig. 1, a runway 6 supporting the ends of the work by supports 7, a device 15 for rotating and feeding the work axially, and a clamp 12, operable when the feeding-device is released and the welding equipment 29 is operating. The feeding-device comprises shoes 16, Fig. 4, connected to arms 15 which grip the work 8 when a pneumatic double-acting cylinder 17 moves the arms about a pivot 15a. A similar cylinder 22 is connected to one of the pins 18 on the arm 15 by a yoke 20, the pins being guided in plates 23 adjustably bolted to plates 19, the latter being adjustable to the vertical so that, when the feeding-device is rotated by the cylinder 22, it will also move axially. The clamping-device comprises shoes 13, Fig. 3, connected to arms 12, which clamp the work when a pneumatic cylinder 14 is' actuated, the device being fixed against rotation. Tn operation, the work 8 is supported by two sets of adjustable-rollers 10 secured to frames 9, cylinder 17 is actuated and the shoes 16 grip the work; the cylinder 22 is then actuated, thus turning the work and feeding it axially according to the setting of guide-strips 23 on plates 19. The cylinder 14 is actuated, and the work is clamped by shoes 13. Cylinders 17, 22, are then reversed to return the feeding-device to its initial position, and a stud is welded to the work. Cylinder 14 then releases the workclamp, and as the operations are repeated, the studs are welded to the work in a helical path. The pitch of the studs can be varied by adjusting the stroke of cylinder 22, or by limiting'the stroke by stops 31. The machine is automatically-controlled by a cam 26 driven by a motor 25 and controlling valves for cylinders 14, 17, 22, and for the operation of the tool &c. 29. The welding-machine may incorporate a vibratory feed-bowl 28 and a magazine 29 from which one stud is fed and arc-welded at each operation.

Title: Improvements in or relating to modulating arrangements, suitable for use in wireless and other high frequency signalling systems
IPC: H03C1/22
Filed: 1930-01-07
Abstract: 343,678. Valve modulating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 13, Hallesches Ufer, Berlin. Jan. 7, 1930, No. 635. Convention date, Jan. 7, 1929. [Class 40 (v).] In modulating arrangements of the kind in which the signals vary the grid voltage of a valve 2 connected in the grid directcurrent circuit of the high-frequency valve 1 ; and in which an auxiliary valve 3 having its grid circuit directly affected by the signals is connected between the grid and plate of the valve 2 ; a battery 4 and resistance 5 are connected in the grid circuit of the valve 2, and a battery 6 in the grid circuit of the auxiliary valve 3, both batteries tending to make the grids negative relatively to their associated filaments. When the signal applied through the transformer reduces the negative bias on the grid of valve 3, current passes from the condenser 8 through the valve 3 and resistance 5. The grid of valve 2 is thus made less negative or even positive. By thus operating the valve 2 with a positive grid, the heavy grid current of the main valve 1 may be passed without using an excessive number of valves 2 in parallel. As the grid of valve 3 is maintained negative, no grid current passes through the input transformer 7 ; whilst the grid current of the valve 2 can pass through the filament-plate path of the valve 3. For telegraphy, a keying relay may be arranged to short the grid and filament of the valve 3, and a high resistance may replace the secondary of transformer 7.

Patent GB-344066-A (GB)
Title: Improvements in or relating to controlling means for variable speed gearing
IPC: F16H61/02
Filed: 1929-09-02
Abstract: 344,066. Controlling variable speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A. Sept. 2, 1929, No. 668/31. Convention date, May 7, 1929. Divided on 343,988. [Class 80 (ii).] Variable-speed gearing upon, say, a car, is controlled automatically by a fluid-pressure system in which the pressure is proportional to the speed of the engine, and in which the drive is engaged, and the speed ratio increased, by speeding up the engine by opening the throttle. The only necessary controls are the accelerator and service brakes. The invention is described as applied to the twin planetary torus disc arrangement operating by precession described in Specification 343,988. The gearing is operated as to speed changes by a piston 95. With the car standing and engine idling, pump 85, Fig. 7, driven by the engine shaft, is driving oil ineffectively past speed valve 89, which is set for the purpose. To start the car, the driver speeds up the engine by the accelerator, whereby oil overflowing valve 89 passes by pipe 91 to valve 115, which it opens, then by pipe 109 into cylinder 108, pressing piston 106 to the right and applying brake 72 to an abutment gear member, as described in Specification 344,063. The car starts off in lowest gear, which may be rapidly increased. After brake 72 is fully on, oil banking up in pipe 91 forces valve 135 to the left and passes to speed control cylinder 96 in which piston 95 is then held at left by a spring and by torque reaction. Sufficient engine speed thrusts piston 95 and gear-operating slider 46 to the right, precessing the gear rollers and so accelerating rapidly to the capacity of the engine. Further speeding up of the engine at this point causes piston 95 to uncover pipe 98 by which oil passing to differential valve 116, 115 releases the oil pressure between the brake pistons 106, 107 and applies pressure to a piston 106a so as to release the brake 72 and apply clutch 78 for solid driving, all as described in Specification 343,988. Increased torque or reduced throttle opening restores the parts to the position of Fig. 7 with the brake 72 applied and automatic geared drives in operation. To stop the car, it is only necessary to close the throttle and apply the service brakes. Closing the throttle returns the gear rollers to the low-speed position and releases brake 72, so that the drive ceases. Depression of service brake pedal opens valve 92, which releases the oil pressure in the whole system. To drive reversely, reverse shift rod 68 is moved manually to the left. This interchanges the connections of the gearing and disconnects the speed control cylinder 96. The car is started in reverse as in forward driving. Specification 344,061 also is referred to.
