Abstract: 378,497. Sound reproduction ; picture transmission. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Kingsbury, E. F. ; 121, Woodward Avenue, Rutherford, New Jersey, U.S.A.) May 13, 1931, No. 14111. Convention date, May 24, 1930. [Class 40 (ii).] In sound reproduction, picture transmission &c. wherein a light sensitive cell is subjected to light from a lamp supplied with alternating current, or otherwise including an undesirable component, provision is made for modulating the current in the cell to neutralize the effect of the fluctuations of the lamp. For this purpose, the cell 7 is subjected to a magnetic field, preferably along the axis of the cell, produced by an electromagnet 18 which is excited from the source 14 of current supplying the lamp and through a circuit including a potential divider 17 and a phase shifting network comprising a condenser 20, an inductance 21 and a resistance 22 in parallel. By adjustment of these elements in the circuit so that when the light is directed unimpeded to the cell there is no effect on the cell current due to fluctuations of the lamp, these fluctuations are completely neutralized in the cell circuit. This compensation does not however, effect reproduction from a sound record such as 4 of variations of a similar frequency to those neutralized frequencies.

Filed: 1955-05-18
Abstract: 823,766. Percussive tools. GRAHAM, C. W. May 18, 1956 [May 18, 1955], No. 14317/55. Class 124. A pneumatically operated percussive tool comprises a cylinder having a closed working end, a piston having a rod extending through the working end, an inlet for the admission of compressed air to the working end and an exhaust valve opening in the working end, an air cushioning and expansion chamber at the other end of the cylinder, control means for opening the exhaust valve when the pressure in the expansion chamber reaches a predetermined maximum to produce a working stroke by the air compressed in the expansion chamber and closing the exhaust valve when compressed air is admitted to the working end of the cylinder, and means to admit air to the expansion chamber through a pressure regulating valve when the exhaust valve has been opened. As shown, a cylinder 1 is closed at the working end by a plate 3 and has a piston 4 with a rod 5 passing through the plate 3. A valve 9, having bores 8, surrounds the rod 5 and is movable in the cylinder by an amount governed by a stop 12 to open and close exhaust ports 10. Compressed air entering below the valve 9 first raises the valve to cover the exhaust ports and then, passing through the bores 8, moves the piston 4 upwardly compressing the air in the chamber 15 above the piston. When the pressure in the chamber 15 reaches a predetermined maximum value a control valve opens the space below the valve 9 to atmosphere, allowing the valve 9 to drop, and the compressed air below the piston is exhausted to atmosphere through the ports 10. The air in the chamber 15 then expands and produces a working stroke of the piston. When the air pressure in the chamber 15 reaches a predetermined minimum value the control valve again admits air below the exhaust valve and the cycle is repeated. Air is admitted to the space 15 through a regulating valve 17 to maintain a desired minimum pressure therein. The piston 4 and end plate 3 may be provided with rubber discs 4a and 14 respectively to absorb shock. In a modification, Fig. 4 (not shown), the cylinder above the exhaust ports may be enclosed in a bell shaped cover, the end wall 2 being removed. Shields to deflect the exhaust downwardly and a flexible ground engaging element may also be provided.

In order to prevent the diaphragm of a vacuum brake cylinder from being distorted sideways during its upward movement in the brake - applying direction, causing wear in the guide bush when atmospheric air is admitted into the vacuum brake pipe, thus raising the pressure in the lower chamber communicating therewith which acts on the underside of the diaphragm and causes the piston member to rise, the vacuum brake cylinder is provided with a piston-rod passing freely, without lateral restraint, through an aperture in the lower portion of the cylinder; the leakage of air through the aperture being prevented by a flexible sleeve or gaiter clamped at its ends around the aperture and piston-rod respectively. In the embodiment shown in Fig. 1, the increased pressure of air in lower chamber 24 during a brake application acts uniformly around the diaphragm 6 and keeps the piston member 11 substantially central within the cylinder and permits, at the same time, limited lateral movement of the piston-rod 18 in aperture 22 in bush 14 to allow for any uneven flexing of the diaphragm 6 as it rolls up and down in the inner surface of the cylinder guide 2. Flexible sleeve or gaiter 17 seals the aperture 22 of the bush 14 without restricting movement of the piston-rod 18. Fig. 2 illustrates alternative means for limiting the lateral movement of piston 11 during release of the brakes; wherein the piston-rod 18a is hollow and is open at its upper end into which extends a guide-rod 27 depending axially from the cylindrical cover 1 to which it is rigidly secured.
