Title: Automatic flushing apparatus, especially for water closets
IPC: E03D3/08
Filed: 1949-10-07
Abstract: 662,128. Flushing cisterns. SCHECH, G. Oct. 7, 1949. [Oct. 12, 1948] No. 25838/49. Class 26. An automatic flushing apparatus comprises a base plate 1 to which the water supply pipe 2 and the water outlet pipe 3 are fitted the pipe 2 having a valve seat 4 with which a valve 5 co-operates the valve being held on its seat by means of a cross member 6 carried by a sleeve 7 interposed between the pipes 2, 3. The sleeve 7 is provided with a cap nut 8 and an annular recess 9 within which is housed a spring 10 which serves to keep the sleeve 7 in a position to keep the valve 5 closed against the water pressure. A lever 13 is pivoted at 14 to the base plate and has one end forked to engage guides 12 on the sleeve 7 and the other end provided with a roll 16 and an arm 15 pivoted to a gear 17 which is part of a motion retarding device. Also pivoted to the base plate at 19 is a balancing lever biassed by a spring 23 so that the roll 21 bears on the roll 16 of the lever 13. The other end of the lever 20 is provided with a depression 22 with which engages a roll 31 on the end of a link 29. The link 29 is pivoted to the arm 27 of a bell crank lever the other arm of which constitutes the operating handle 25, 26, the arm 27 having a stop 28 against which the link is tended to be drawn by a spring 30. In operation on swinging the handle 25, 26 over the link 29 descends and pushes the end of the balancing lever 20 so that its other end operates the lever 13 to cause the sleeve 7 to descend against the pressure of the spring 10 and so opens the valve 5. During this time the link 29 moves away from its stop 28 and its end finally leaves the depression 22 on the lever 20 allowing the spring 30 to draw the link 29 back against its stop 28 and the handle 25. 26 returns to its initial position but is ineffective to operate the flushing system since the end of the lever 20 has not returned to a position wherein it is engaged by the roll 31 on the link 29. The spring 10 tends to reset the valve &c under the control of the motion retarding device 17, 18.

Title: Improvements in magnesia refractories
Filed: 1936-09-24
Abstract: A magnesia refractory is made by treating sea water or other natural brine containing convertible magnesium salts, with calcined dolomite or dolomitic limestone, which may be in the form of a slurry, without the application of heat, removing the precipitated magnesium hydroxide and subjecting it to calcination to form a clinker. Substances suitable for binding agents may be introduced into the brine or slurry before precipitation, or mixed with the precipitate or incorporated in the water used for washing the precipitate. Suitable substances are the compounds of calcium, silicon, iron, aluminium, chromium or zirconium.  The precipitate may then be concentrated and directly introduced into a rotary kiln or applied as a paste to a flat surface or network on which it may be dried in a tunnel drier.  The dried product may then be calcined and ground. The particles are said to be elongated and thereby are more easily bound together.  The preparation of a brick is described wherein the clinker is crushed, sieved and graded, the graded material being then remixed in the proper proportions, moulded and calcined. Specification 482,339 is referred to.ALSO:A magnesia refractory is made by treating sea water or other natural brine containing convertible magnesium salts, with calcined dolomite or dolomitic limestone which may be in the form of a slurry, without the application of heat, removing the precipitated magnesium hydroxide and subjecting it to calcination to form a clinker.

Title: Transducer device
IPC: G01D15/24
Filed: 1972-06-03
Abstract: 1411402 Recording apparatus R G HICKS 29 May 1973 [3 June 1972] 26020/72 Heading G1J An oscillatory drive mechanism for a recorder comprises an input signal selector switch 15, an oscillatory mechanism 11 having a power stroke and a return stroke, a motor 10 to drive the selector switch and the oscillatory mechanism in synchronism, an oscillatory power train 12 drivable by the oscillatory mechanism 11, a solenoid 13 connected in an electrical circuit with the selector switch 15 to respond to input signals, and a control member 14 movable by the solenoid 13 between a blocking position in which it obstructs the return strokes of the power train 12 to stop power transmission thereby, and a clear position, so that the output movements of the drive mechanism are controlled in response to the input signals. The motor 10, which may be electric or clockwork, runs continuously. Its output shaft 18 carries a star wheel 19 which rocks a lever 26, and a gear 20 which, via gears 22, 23, rotates a shaft 21 carrying the spring contact arm 24 of the selector switch 15 over fixed input contacts 25. The rocking lever 26 rocks a lever 29 about a shaft 31 and makes one complete oscillation each time the contact arm 24 traverses a contact 25, the end of the power stroke occuring as the arm 24 reaches the centre of the contact 25 it is traversing. Contacts 41 of a switch 16 in series with the solenoid 13 are momentarily closed by the lever 29 at the end of each power stroke. The cranked armature 38 of the solenoid pivots on a fulcrum 39 and its arm 40 engages the control member 14. Arms 32, 33 secured on the shaft 31 have crank pins 34, 35 respectively, the pin 34 being engageable by the lever 29 to rock the shaft 31. The arm 33 is raised during a power stroke, and if the solenoid is not energized the control member 14 drops to the position in Fig. 3 to block the return stroke of the arm 33 and shaft 31. This occurs if there is no input signal to the contact 25 being traversed. If an input signal is present, it energizes the solenoid during closure of the switch 16 to raise the control member 14 sufficiently to allow the shaft 31 to complete its return stroke, and hence to enable it to make the following power stroke. The shaft 31 provides the drive to the recorder and may produce a counter reading and a binary print-out for the signals, a code or space shift for each input, and a datum reading and print-out for each reciprocation of the mechanism. The shaft 21 may carry and  drive a print-out drum.
