Title: Ship's bell clock
IPC: G04B21/02
Filed: 1959-10-30
Abstract: 908,510. Clocks. GENERAL TIME CORPORATION. Oct. 30, 1959 [April 24, 1959], No. 36880/59. Class 139. In a ship's striking clock the striking mechanism comprises a spring 27 (shown diagrammatically), gearing 41, 42, 44, 45, 47, a vane 43, and a double star-wheel 25a, 25b which cooperates with an arm 30 to transmit movement to the hammer 22 through the linkage 31, 33, 34. The shaft 40 of the striking train carries a two-lobe cam 50 which is normally locked by a detent 55 pivotally mounted on a shaft 57 on which is also pivoted the lifting piece 60 the end 61 of which co-operates with a cam 62 having an hour lobe 63, a half-hour lobe 64 and a forty-five minute lobe 110 the purpose of which is described later. The extension 70 of the lifting piece 60 locks the gear 47 of the striking train when the lifting piece 60 is raised by the cam 62 until drop-off occurs when the striking train is freed. The periphery of the hour snail 80 is divided into three groups of eight steps. The detent 56 has a rack hook extension 100. The gathering pins 101, 102 extend from the cam 50 on the shaft 40. At the forty-five minute position the lobe 110 of the cam 62 raises the lifting piece 60 to remove the detent 55 from the cam 50 and at drop-off the striking train is freed for one half revolution of the cam 50 which is then arrested by the detent 55. During this half revolution the star-wheel 25a, 25b is rotated one step but the hammer is not actuated as the silencing cam 115 on the minute shaft 11 engages the lever arm 32 to remove the arm 30 from the star-wheel 25a, 25b. The striking mechanism is thus conditioned to strike an even number of blows on the hour. If the hand-setting mechanism is actuated to move the minute hand from a position in advance of, to a position before the forty-five minute position, the shaft 40 is not released again by the lobe 110 acting on the lifting piece since the lobe 51 of the cam 50 is too big to be released from the detent 55.

Title: Chemical migration ratio instrument
IPC: G01N27/447
Filed: 1974-09-09
Abstract: 1488378 Measuring displacement electrically SINDCO CORP 9 Sept 1974 37102/74 Heading G1N An instrument for measuring chemical migration ratio includes a pointer 44 carrying a hairline 42 and movable over and along a reference line 40 on an underlying panel 38 on which, in use, chemical samples migrate in a solvent from an origin towards a solvent front line 62. The distance migrated is measured by aligning visually the hairline with a test point on the panel and determining electrically the distance between the origin and the test point and the distance between the origin and the solvent front line. The ratio of these distances is the chemical migration ratio, Rf. Alignment of the pointer is effected by manipulation of a knob 46 which causes the resistance of variable resistance Rd to be varied. Similarly resistances Rc, Rm are varied by control.knobs 48, 50. Initially the pointer is set to the origin and meter 94 zero reading set by resistance 116. Next the pointer is positioned over the solvent front line 62 and calibration knob 48 manipulated to vary resistance Rc to bring the meter needle to full scale deflection. The switches are set as shown in Fig. 8. The drive control knob 46 is again rotated to align the pointer with a first test sample point (88), Fig. 5(a) (not shown). This varies resistance Rd and the resulting meter reading represents a first chemical migration ratio Rf 1 . Comparison reading, Rx The drive control knob is reset to bring the pointer 44 into alignment with a second test sample point and to vary the resistance Rd again to provide a second reading Rf2. Next the memory push button 54 is depressed so switch 140 makes with station 146 and the resistance Rm is substituted for resistance Rd in the amplifier 110 feedback loop. The memory control knob 50 is rotated to set Rm so that the meter 94 reads the same as for the original ratio Rf 1 . The Rx push-button 52 is then depressed to charge switch 126 to station 148 with switch 100 at station 114 and switch 140 at station 144. The resistances Rm, Rd are respectively the input and feedback resistances of the amplifier. Consequently the meter reading corresponds with the ratio of the two migration ratios Rf 2 /Rf 1 . In an alternative embodiment, Figs. 4, 9 and 10 (not shown), the memory pointer 28 is omitted and a digital read-out is provided but otherwise the operation is the same.
