Title: Improvements in detectors of light-absorbing fluids
Inventor: CHURCHILL JOHN GODWYN
IPC: G01N21/53
Filed: 1960-03-01
Abstract: 915,321. Turbidometers. GRAVINER MANUFACTURING CO. Ltd. Feb. 27, 1961 [March 1, 1960], No. 7153/60. Class 97 (3). [Also in Groups XXIX and XL (b)] Apparatus sensitive to suspended matter in a plurality of fluid samples comprises two tubes through which light is directed to photo-cells and a valve supplying said samples and a neutral fluid to one of said tubes in turn. Light from a source 8, Fig. 2, reflected by mirrors 7, 7<SP>1</SP> through averaging and sample tubes 3, 3<SP>1</SP> impinges upon a silicon or vacuum photo-cell 4, 41. Pipes 29 connect a rotary control valve 24 (see Group XXIX) to various points in a diesel engine which are to be monitored for oil mists. The rotor 30 of valve 24 has positions in which pipes 29 are connected in turn to the sample tube via pipe 23<SP>1</SP>, the remaining pipes 29 all communicating with the averaging tube 3. A motor 13 serves to step the rotor 30 on through a Geneva cross mechanism and to draw the various gases through the tubes which are provided with sleeves 5, 6 to prevent deposition on the windows 18. The outputs of cells 4, 4<SP>1</SP> are connected differentially to a meter 33, the pointer of which loses a contact to give an audible or visual warning. The apparatus compares the oil mist density in each sample with the mean of the samples and so gives an alarm only when one sample is different from the rest. If different parts of the engine are expected to have different mist densities, valves may be included in pipes 29 to equalize them. In a further position of rotor 30, clean air is connected to tube 3<SP>1</SP> and all the samples are connected to tube 3 for measuring an absolute density. In a calibration position of rotor 30, all samples are connected to both tubes and the angle of mirror 7<SP>1</SP> is adjusted until the output of the cells is equal. The meter 33 must have different sensitivities for the various functions and this is achieved by varying its shunt resistors by cam-operated switches, Figs. 6 and 8 (not shown). In a modification for detecting smoke in diesel exhausts, the averaging tube is replaced by a closed tube 113, Fig. 10, having a vane 170 rotatable in conjunction with a Ringlemann scale 173. Vane 170 is either set to a maximum smoke value, and the difference in output used to actuate an alarm or it is adjusted to reduce the difference to zero, the position on the scale then indicating the smoke density. The Provisional Specification also discloses the use of a selenium cell in place of the silicon cell. Specification 915,322 is referred to.

Title: A timing device driven by a fluid pressure operated motor
IPC: G04F1/00
Filed: 1960-03-03
Abstract: 892,558. Clocks. CAMCO Inc. March 3, 1960 [March 13, 1959], No. 7525/60. Class 139. A timing device, e.g. for timing gas injection cycles in oil wells, is driven by a fluid-pressure operated motor comprising a spring-loaded diaphragm 4 clamped between two casing parts 2 and 3 to define a chamber 7 which receives gas under pressure via an inlet 9 and an orifice 10. A tube member 12 carried by the diaphragm 4 extends out of the casing 2, 3 and its end 13 co-operates with a valve member 18, 19, 20 carried by one end of a pivoted lever 21 the other forked end of which co-operates with an impulse pin 23 of a balance-balance spring assembly 24, 26. The tube 12 carries a pawl 29 which drives a ratchet 28 constituting the first gear of the timing train. The arrangement is such that the diaphragm 4 is moved upwardly by the gas pressure against the force of the spring 17 and the tube 12 rocks the lever 21 which impulses the balance in the clockwise direction. As the balance 24 continues its clockwise swing it moves the lever 21 to withdraw the valve member 18, 19, 20 from the end 13 of the tube 12 to vent the chamber 7 and allow the spring 17 to return the diaphragm 4 to its initial position. When the balance 24 returns in the counter-clockwise direction the pin 23 moves the lever 21 to restore the valve member to its position against the end 13 of the tube 12 so that the cycle repeats. The amplitude of the balance swing may be determined by two resiliently mounted adjustable stops. The valve member 18, 19, 20 may be replaced by a poppet type valve loaded by a coil spring.
