Title: Improvements in and relating to hot-water boilers
IPC: F24H9/18
Filed: 1947-02-13
Abstract: 635,908. Water-heating stoves. SATCHWELL, L. Feb. 13, 1947, No. 4199. [Class 126] [Also in Groups XIII and XX] A hot-water storage boiler comprises a fuel container 3, a fire chamber 2, a heat exchange flue 4 and a thermally-actuated indicator which is sensitive to the average water temperature throughout the storage space to give an indication of the quantity of stored hot-water. The water to be heated is contained within a cylindrical storage vessel I and is indirectly heated by water contained in a primary water vessel 5 interposed between the firechamber and flue passage and the water in the cylindrical storage vessel. The thermally-sensitive element comprises an expanding tube 9 penetrating the whole depth of the water in the vessel 1 and connected at its end remote from the support 10 to a non-expanding rod 11. Movement of the rod I caused by a change in the mean water temperature raises or lowers a suitably marked indicator 6 through the arm 12, the indicator being visible through a window 7. Primary air for combustion enters the fire chamber through a port 20, which can be closed by a door 21. The supply of combustion air may be controlled by a hand reset flap 22 (Fig. 3) which is dropped automatically to the closed position if the set maximum temperature is exceeded in the stored water. A catch 23 holds the flap open until upward movement of the rod 24 actuated by the indicator arm 12 and due to an increase in the mean water temperature, releases the flap to close the air entry port. In a further arrangement (Fig. 4), the fuel container lid 18 is locked in position at a pre-determined water temperature by the action of the thermallysensitive element. A spring-loaded bolt 26 actuated by an arm 28 which is connected to the indicator arm 12, engages a hole 27 formed in a downward extension 25 provided on the lid 18. When the temperature of the stored water has fallen sufficiently to absorb the heat of a further charge of fuel, the bolt is withdrawn from engagement with the hole 27 and the lid can be raised to allow the fresh charge to be inserted. Heat insulation 17 may surround the water vessel 1.

Title: Pneumatic liquid waste material conveying system
IPC: E03D11/00
Filed: 1976-02-04
Abstract: 1522891 Raising liquids THETFORD CORP 4 Feb 1976 [28 May 1975] 04393/76 Heading F1R [ Also in Division E1] Liquid waste from a flushing closet 12 or other receptacle is intermittently (e.g. at each flush) (a) sucked into a surge tank 36 and (b) allowed to fall into a tank 32 when the tank 36 is vented, the necessary partial vacuum in tank 36 being created by a pump 50 intermittently connected thereto through a control 52, and the surge tank 36 having a bottom discharge 38 closable by a ball float 46 in a conduit 42 whose lower end is in tank 32 below a maintained level 34 of liquid waste. The closet pan 12 has an air vent 30, a flush lever 24, a flushing sensor switch 28 and a suction soil pipe 22 incorporating a trap 48. The level 34 is maintained constant by spill-over into a treatment tank 16. The pump 50 runs continuously. The surge tank 36 has a maximum level sensor switch 68. The control circuit, Fig. 2 (not shown) incorporates a time delay switch (82) and is such that whenever switch (28) senses a flushing operation a solenoid valve (56) is shifted for a predetermined time to connect pump 50 to tank 36; initially then liquid rises up conduit 42, causing ball 46 to close port 38, whereafter liquid is sucked from conduit 22 and closet 12 into tank 36. When time delay switch (82) cuts out, valve 56 is spring-returned to vent tank 36, so that port 38 opens and contents are discharged. If liquid rises too far in tank 36 (e.g. due to fouling of ball 46) then level sensor switch 68 co-operates with a second time delay switch (78) in the circuit to cause a repeat of the cycle.

Filed: 1943-03-24
Abstract: 564,396. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). March 24, 1943, No. 4773. [Class 38 (ii)] An A.C. supply 3 is converted into D.C. 1, 2 by valves 5, 6, 7 having control members 14 of the immersion-igniter type which are excited. by peaked impulses of current from a resonant circuit such as 20, 21 having a natural frequency substantially greater than that of the supply circuit. In the form shown, a discharge device 23 in the resonant circuit allows current to pass to the control member 14 in the right direction only when its grid 24 has a positive potential which is when the current in a winding 29 is at its peak value and overpowers the battery 32. The exact timing-of the impulse may be adjusted by a phase shifter 27 and its duration is short because of the high natural frequency of the circuit 20, 21. In a modification, Fig. 4 (not shown), a second discharge device oppositely arranged, is placed in parallel with the valve 23 and the cathode .13 so that the resonant circuit may oscillate and produce a series of impulses at 14, till the starting of current in the valve 5 biasses the grid of the discharge device so as to render it non-conducting. In another modification, Fig. 5 (not shown), the resonant circuit is energized from the same transformer 4 that supplies the valves 5, 6, 7, and two discharge devices are connected in series with the control member 14, one becoming conductive at the precise time desired substantially as in the previous arrangement and the other becoming conductive when the condenser 21 forming part of the resonant circuit becomes sufficiently charged.

Title: Improvements in talking machines, recording and reproducing at constant linear speed
IPC: G11B19/265
Filed: 1932-02-18
Abstract: 402,046. Gramophones. DEBREBANT, G., 119, Rue Gaulaincourt, Paris. Feb. 18, 1932, No. 4827. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 25, 1932]. [Class 40 (ii).] A constant linear speed drive mechanism for gramophones is provided with a system of counterweighted levers for the purpose of increasing the pressure of the driving roller 1 on the underside of the turntable 8 and for varying the resistance to the drive as the driving roller 1 moves across the underside of the turntable and increases the angular speed of the turntable. The driving roller 1 is mounted on a lever 2 which is provided with an adjustable counterweight 6 and is pivoted on the shaft 3 of a motor adapted to drive the roller through gearing 4, 5. The turntable 8 is mounted on a carriage 7 which is displaced over the roller 1 during recording or reproducing, and a rod 10, having a counterweight 12, is pivoted to the carriage at 11 and engages a roller 13 on the lever 2. As the carriage 7 is displaced, the counterweight 12 effects an increase in the pressure of the driving roller on the turntable, and also, in the case of sound-recording apparatus, tends to lift the carriage 7 and turntable and thereby diminishes the resistance to the drive. In the case of reproducing apparatus, the counterweighted lever 10 is so arranged that the action of the counteiweight 12 serves to increase the resistance to the drive.

Filed: 1957-02-13
Abstract: In a composition adapted to be dissolved in water to produce a germicidal iodine solution which comprises an N-monochlorosulphonamide, e.g. chloramine-B or chloramine-T, and an iodide, e.g. potassium iodide, capable of reacting with the sulphonamide in the presence of water to produce iodine, the sulphonamide has been partially dehydrated to such an extent that substantial reaction and release of iodine does not take place during storage of the composition, while the crystal structure of the fully hydrated sulphonamide is retained.  The lower limit of the degree of hydration of the partially dehydrated sulphonamide, expressed in mols. of water per mol. of anhydrous sulphonamide, is about 0.5.  The upper limit depends somewhat on the sulphonamide employed.  It is about 1.5 for chloramine-T and about 1.75 for chloramine-B.  Example I specifies the use of chloramine-T which has been heated in vacuo at a temperature of 85 DEG  C. to produce a product having a degree of hydration of 1 and a relative vapour pressure of 0.1, in a composition which also comprises potassium iodide, citric acid and sodium bicarbonate.  Example II specifies the use of chloramine-B which has been heated in vacuo at a temperature of 90 DEG  C. to produce a product having a degree of hydration of 1.25 and a relative vapour pressure of less than 0.1 in a composition which also comprises potassium iodide and sodium dihydrogen phosphate.ALSO:In a composition adapted to be dissolved in water to produce a germicidal iodine solution which comprises an N-monochlorosulphonamide, e.g. chloramine-B or chloramine-T, and an iodide, e.g. potassium iodide, capable of reacting with the sulphonamide in the presence of water to produce iodine, the sulphonamide has been partially dehydrated to such an extent that substantial reaction and release of iodine does not take place during storage of the composition, while the crystal structure of the fully hydrated sulphonamide is retained.

Abstract: 960,284. Dressing grinding wheels. H. CHANDLER. Feb. 11, 1963 [Feb. 9, 1962], No. 4997/62. Addition to 906,757. Heading B3D. The multi-diamond dressing tool of the parent Specification has the individually-adjustable diamond-carrying slugs 12 secured in their holder 10 by means comprising a plurality of locking members 16, Fig. 3, or 24, Fig. 4, which are transversely movable relative to the slug axis by a common wedging member 17 movable in a direction transverse to that of the locking members so that, when the wedging members forced into its locking position, the locking members are forced into locking engagement with the slugs but, when withdrawn, the slugs are released for adjustment as required. When more than two slugs are used they are arranged symmetrically about the axis of the holder 10. Fewer diamond slugs than sockets in the holder may be used, dummy slugs of shorter length being inserted in the " blind " sockets. The embodiment of Fig. 3 shows balls in use for the wedging and locking elements but the operating screw 14 may have a conical mixer end to provide the wedging action when screwed inwards. In a further modification, Fig. 4, the locking members 24 are formed by short lengths of rod. These are preferably inserted into the radial holes of the holder before the slug-sockets are drilled in the holder so that their slugengaging ends are shaped to provide a bearing surface on the slugs, the inner ends of which are knurled to enhance the locking action. The inner ends of the locking members are cut at an angle to engage the wedging member; they may be shaped by a drill inserted in the screwed central hole of the holder. The Provisional Specification states that a larger ball is used for the wedging member than those used for locking the slugs.
