Title: Improvements in or relating to the motors used in combined cinematograph and phonograph productions
IPC: G03B31/00
Filed: 1921-01-28
Abstract: 183,763. Johnson, A. T. M. Jan. 28, 1921. Acoustic and vibrationfrequency speed indicators with indicating apparatus. -For indicating the running at the correct speeds of the motors driving a kinematograph and one or more gramophones operating in synchronism therewith, a tuned reed, which continues to vibrate only so long as the proper speed is maintained, is associated with each motor. Fig. 2 shows the speed-indicating and regulating means for two gramophones o worked in connection with a kinematograph. Each motor 4a drives a commutator u in a circuit including an electromagnet s, of which the tuned reed w forms the armature, so that it will vibrate only so long as the current impulses accord with the pitch of the reed. The speed is controlled by a rheostat g. A combined starting-switch and brake lever e may be fitted, and also a switch p<1 >to cut out the resistance d for rapid starting.

Title: Improvements in or relating to electronic indicating or warning apparatus
IPC: G08B13/24
Filed: 1948-11-03
Abstract: 668,374. Indicating proximity of bodies. JOHANSSON, K. L. Nov. 3, 1948 [Nov. 12, 1947], No. 28602/48. Class 37. An electronic device for indicating the presence of a body comprises an oscillator valve F1 whose output is rectified and taken via a smoothing network R2, R3, C4, C5 to the control grid of an amplifying valve F2, containing a relay winding Re in the anode lead. The presence of a body near an aerial A damps the oscillator output and reduces the grid voltage of F2 to cause the anode current to rise and energize relay winding Re. Changes in the supply voltage are compensated in valve F2 by the neutralizing effects of the resulting changes in grid and anode voltage.

Title: Improvements in or relating to flushing apparatus
IPC: E03D1/30
Filed: 1938-10-03
Abstract: 519,797. Valve-discharge water-waste preventers. JACKSON, L. MELLERSH- (Teahen, J. M.). Oct. 3, 1938, No. 28712. [Class 26] In a valve-discharge flushing apparatus in which the inlet and outlet are controlled by normally-closed valves, the inlet valve is opened upon lifting of the discharge valve and is kept open after the closing of the discharge valve until the water in the tank rises to a predetermined level, when it is closed. The inlet G is arranged axially within an annular member D to which it is connected by hollow radial spokes 11 and is threaded to pass through an opening in the outer wall I of a tank A, being secured thereto by a gasket G<2> and nut G<1>. The supply through the inlet G is controlled by a valve K screwed to the part G, the upper position of the valve being located within an enlargement G<3> leaving an annular space communicating with the spoke H. Fitting within the part K is a member N having a central passage N' and an enlarged portion N<2> at its lower end which connects with ports N<3> opening into the periphery of the part N. Fitting on the reduced top of the part N is a flexible diaphragm L which is secured thereto by a threaded cap O which contains a ball O held by a flange O<2> having an aperture and is also clamped on to a shoulder G<4> of the part G by a member M which is extended upward to form a guide for the flushing valve P. The lower annular portion P<1> of the valve is provided with a gasket P<3> which normally rests upon the part D, and also with a tubular portion P<3> which rises to the desired level of the water in the tank A. The upper part of the member M is provided with an extension M<1> with a part K on its underside normally sealed by a ball valve M<2> and with an aperture in its top closed by a cap M<3>. Pivotally supported on the member M is a trip lever Q provided with a finger Q' extending beneath the ball M<2> , and with a cup portion Q<3>. The normal position .of the various parts is shown in Fig. 1. the water standing in the tank A up to the level of the upper end of the member P'. To effect flushing, the valve P is lifted by a lever R operated by a handle R<1> and will remain so during the emptying of the tank, and during its upward movement the cam P<4> contacts with the portion Q<2> of the lever Q and tilts it, causing the finger Q<1> to unseat the valve M<2>, thus exhausting pressure from the member M and causing the diaphragm L to be raised. Water from the pipe G will then pass over the part K into the chamber G<3> and spokes H into the tank. After the valve P re-engages the seat D, water will continue to flow into the tank until the latter is full, whereupon the overflow filling the cup Q<3> will again tilt the lever Q into the position shown, thus permitting the reseating of the valve M<2> and forcing the diaphragm L against the seat K. The discharge opening J is formed in the inner wall of the tank.
