Title: Process and device for utilising and measuring the variations of illumination
IPC: G01J1/54
Filed: 1937-05-28
Abstract: 477,257. Mercury switches. CHILOWSKY, C. May 28, 1937, No. 14914. Convention date, May 28, 1936. [Class 38 (v)] [Also in Group XX] Relates to apparatus of the kind described in Specification 463,994 for indicating intensity of light or utilizing variations in light intensity to control electric circuits, in which the light is incident on a closed chamber in which hydrogen and chlorine are produced by the electrolysis of HCl, the gases recombining under the action of the light at a rate depending on the light intensity. According to this invention a small uni-directional potential difference is maintained between the electrodes when the apparatus is inoperative, in order to prevent the electrolyte from attacking the electrodes. As shown, a U-tube 5 containing mercury receives the variations of pressure in the electrolysis chamber 1 through a flexible membrane 7. When the intensity of the light incident on the chamber 1 is sufficiently reduced, the mercury reaches the contact 9 and a circuit is completed which may light a lamp 11. When the light is further reduced the mercury reaches the contact 10 and completes a shunt circuit through the resistance 4<1> between the electrodes 2, 2<1>. The potential difference between the electrodes is thus diminished during periods of low illumination. In another form, chiefly intended for use when the apparatus is being transported, a dry battery is provided which can be connected across the electrodes instead of the normal source of current to provide the desired steady E.M.F.

The piston 16 operates sucker rod 17 whilst the piston 21 supports a counterbalance weight 23. The bottoms of the cylinders 15, 20 are connected directly by a conduit 27 associated with decelleration valves 28, relief valves 29, and alternative inlet valves 30. A tank conduit 56 is provided to drain off leaking liquid. The tops of the cylinders 15, 20 are connected by conduits 36, 37 to a control unit 35 which contains valves 45, 55, a reversible variable delivery pump 60 driven by a motor 61 and controlled by the piston 62 of a valve block 63, an accumulator cylinder 64, and a replenishing pump 65. The piston 16 is adapted to contact members 38, 40 which are connected together by a rod 39 and to a lever 42 which is connected by a link 43 to the valve 45. The piston 21 is adapted to contact members 46, 48 which are connected together by a rod 47 and to a lever 50 which is connected by a link 51 to the valve 55. The pump 60 is controlled and reversed by means of a member 66 against the action of a spring 72, and is connected to the conduits 36, 37 by inlet-outlet conduits 67, 68 ; a cooling fan 70 and a radiator 69 are provided. The conduits 27, 37 are connected by a conduit 95 to permit filling the conduit 27 at starting. When piston 16 reaches the top of its stroke and contacts member 40, valve 45 is shifted to the left, and valve piston 62 is moved upwards and operates member 66 to permit flow in the pump from conduit 37 and cylinder 20 to conduit 36 and cylinder 15 to start the piston 16 on its downward stroke. At the bottom of its stroke a reverse sequence of operations takes place. Leakage around the pistons 16, 21 is replenished by the pump 65 which is driven by an eccentric on the motor shaft 61, and leads to the twoposition valve 55. The piston 21 is slightly shorter than the piston 16, or the cylinder 20 is slightly longer than the cylinder 15, and, when leakage reaches a certain amount, piston 21 operates lever 46 to move valve 55 to the right, permitting the pump 65 to force liquid into the conduit 27, until piston 21 operates lever 48, and pump 65 is by-passed to a conduit 105. Details of slide and relief valves, and restricted openings for controlling the flow of oil, are given in the Specification, and two modifications are described in which the replenishment of leakage is continuous.
