Title: Improvements in or relating to clock operated electrical alarms
IPC: G04C23/34
Filed: 1933-09-25
Abstract: 419,400. Time-alarm signals. SHIERS, A. H., 104, Loughborough Park, Brixton, London. Sept. 25, 1933, No. 26351. [Class 118 (ii).] In an apparatus for giving alarms at predetermined times on certain days of the week and at other predetermined times on other days of the week, a single contact is provided in the alarm circuit which is closed by an arm cooperating with three cams, the arm dropping to close the signal circuit only when notches in all cams are in positions to allow the arm to fall. In the construction described the Sunday times are different from the week-day times. The cams normally move forward to rotate in one hour, twelve hours and seven days respectively but pawls fixed to the hour cam are arranged to move the seven-day cam to prevent the alarm being given at Sunday times on weekdays and vice versa. As shown in the Figures the cam m rotated once in an hour is provided with slots m<1> corresponding to minutes of the ringing times, the cam Q rotated every twenty-four hours has slots Q corresponding to the hours of the alarm times whilst the weekly cam f<1> has slots g. At an alarm time projections l, l<1> and l<2> on arm t are all in line with slots in the respective cams m, Q and f<1> so that the arm falls to close the alarm circuit at n. If the alarm time happens to be a Sunday time and the day is a weekday, pawl m<2> engages one of the six pins h and moves cam f<1> so that the slot g is out of the path of l<2>. When the pawl leaves pin h the cam springs back under the action of spring k<1>. The pawl m<8> is larger than pawl m<2> and is so shaped that it passes over pins h. On Sundays, however, pin p, which is nearer the shaft c and is longer than pins h is in the path of the pawls so that pawl m<3> becomes effective to move cam #<1> at a different time, the time pawl m<2> being now ineffective. The alarm is therefore sounded at the time it is usually made ineffective by pawl m<2> and is cut out at another time by pawl m<3>. If more than one different time of alarm is to be provided additional pawls m<2>, m<3> are fitted. Plates r enable the hour-ringing periods to be easily altered.

Patent GB-268378-A (GB)
Abstract: 268,378. Fagerholm, P. E. March 27, 1926, [Convention date]. Sights.-Relates to bomb-dropping sights for aircraft, comprising a vertical telescope rotatable about its vertical axis and having means for determining the ground speed of the aircraft. According to the invention, to measure the ground speed, a movable member, for instance a prism in front of the objective, is adpted to be moved to cause an object on the ground to remain stationary in the field of view, and this measuring movement is adapted to set means whereby the bombdropping and burst-observing angles are determined. As shown diagrammatically in Fig. 1, the sight comprises a vertical telescope 1, fixed prism 2, three movable prisms 3, 4, 5 side by side and a shutter 15 adapted to register with one or other of the three prisms 3 - - 5. The prisms 3 - - 5, which are for speed measuring, bomb-dropping, and burst observing, respectively, are independently movable about an axis 16 by means of cams 11 - - 13 engaging rods 6 - - 8 on the prisms. The cam 11 is on a shaft 9 adapted to be turned by a handwheel 10, and the two cams 12, 13 are on a shaft 14 adapted to be coupled to the shaft 9. The shutter 15 is first adjusted opposite the prism 3 which is then moved by turning the handwheel 10 to keep an object on the ground stationary on the crosswires. At the beginning of this movement, the shafts 9 and 14. are coupled together so that the prisms 4, 5 are also moved. After a definite time, such as ten seconds, the coupling is automatically disconnected by timing mechanism, not shown, and the prisms 4, 5 are then in position for bomb-dropping and burst-observing, respectively. The shutter is moved opposite the prism 4 when the bomb is unsecured ready for dropping and is moved opposite the prism 5 when the bomb is dropped. The cams are designed for a definite height and type of bomb and a number of interchangeable cams may be provided for different heights and types, or solid cams axially adjustable may be used. A correction for wind may be obtained by providing an adjustable mark 27, Fig. 5, in the field of view. This mark is carried by a plate 21 which is rotatable about the vertical axis of the telescope, its azimuth position being indicated by a compass 22. The mark is radially adjusted by a cam 23. The settings are determined from tables or from observation of a trial bomb. In a modification, a single prism replaces the three prisms 3 - - 5, its speed-measuring movement setting stops which determine successive positions for dropping and observing.

Abstract: 1348364 Dishwashing machines COLGATEPALMOLIVE CO 9 June 1972 [11 June 1971] 27078/72 Heading A4F [Also in Divisions C1 and D1] A method of treating waste wash water from an automatic clothes washing or dishwashing machine, and containing soluble phosphate, comprises converting the soluble phosphate to an insoluble form by reacting it with a chemical compound at or near the machine and before discharge of the waste wash water to a sewer, drain or other means of disposal. The method is particularly applicable for treating waste wash water containing detergents having therein various phosphates of sodium or other alkali metals, or chlorinated phosphates. The treating chemical compound may be organic or inorganic, and may be an oxide, hydroxide or salt of calcium, aluminium, iron, barium, magnesium, zinc or copper. A device for adding the chemical compound comprises a Venturi tube fastened by clips 75, 77 between portions 79, 81 of the discharge piping and which aspirates the chemical compound from a chamber 73. The treatment with the chemical compound may be prevented by closure of a valve 85 if the discharged liquid is to be collected in a sink 83 for re-use instead of being passed to a drain. In another washing apparatus the additive device has no control valve and the insoluble phosphate is allowed to flocculate in a sink. In further apparatus a filter 131, Fig. 7, (not shown) or 151, Fig. 8, (not shown) is provided for filtering the treated water before it enters or after it leaves a collecting sink (135) or (147). In a further apparatus the chamber of the additive device 157, Fig. 9, (not shown), is disposed above Venturi tube, and the treated water is passed through coiled to multiple looped piping (163) in which the precipitation is completed, and is then filtered. In another apparatus the Venturi additive device is replaced by a cartridge 175, Fig. 10, (not shown) containing a matrix of glass wool or polyurethane foam, and filled with the chemical treating compound. Most of the precipitated phosphate is held by the cartridge which functions as a filter and may be disposable.
