Title: Improvements in feed water regulators for boilers
IPC: F22D5/10
Filed: 1926-09-08
Abstract: 273,118. Dakers, J. E. S. Sept. 8, 1926.- Float valves.-In feed-supply apparatus comprising a pressure-operated feed valve controlled by a float-operated pilot valve in a vessel in communication with the boiler at' the water level therein, the pilot valve consists of a moving sleeve 4a, Fig. 1, integral with the float 2 and a fixed member 4b having ports 5. The valve is completely closed in the raised position of the float by the top of the sleeve seating against the upper end of the fixed member and by the bottom of the sleeve against the lower end of the fixed member. The float may be made of cast iron, steel, or bronze and may be supported on a spring 3 or a spindle connected to a lever carrying a counterbalance weight. The space above the piston feed valve 13, Fig. 3, is in communication with the float chamber through the pilot valve. When the pilot valve is open, the excess feed pressure raises the feed valve and opens thefeed pipe leading to the boiler check valve. When. the pilot valve is closed, water passes through ball valves 16 in the feed valve, and consequently the pressure above the feed valve rising to the feed pressure, the valve is closed. The ball valves are of such a weight that no water passes through them until the lifting pressure acting on the feed valve exceeds the minimum necessary to lift the valve. The valve may be held in its open position by a hand operated spindle 18.

Title: Improvements in gas-fired continuous-flow water heaters
IPC: F24H9/20
Filed: 1953-08-12
Abstract: 727,124. Delivery arrangements for hotwater boilers. VAILLANT, H., [trading as VAILLANT KOMMANDIT-GES., J.]. Aug. 12, 1953 [Aug. 14, 1952 ; June 5, 1953 ; July 10, 1953], No. 22200/53. Class 64 (1). [Also in Group XXIX] In a gas-fired continuous-flow water heater having a water-deficiency safety device responsive to the dynamic pressure fall at a constriction in the path of cold water supply, the pressure fall at the constriction is temporarily eliminated by the closing movement of the delivery valve, so that the water-deficiency safety device cuts off the gas supply to the burner before the flow of water ceases. Thus hot water left in the heater when the burner is extinguished is ejected. In the form shown, a chamber 15 above the diaphragm 5, actuating a gas valve 24 and a water-regulating valve 3, is subjected to a reduction in pressure produced through a passage 14 leading to the narrow part of a venturi 7 in the water supply passage 6. A by-pass 16, 16<SP>1</SP> connecting the chamber 15 to the water inlet is closed by one of two spring- pressed valves 18, 22 when the delivery valve 11 is in its fully closed or fully open position. At an intermediate position of the valve 11, the by-pass 16, 16<SP>1</SP> is open to eliminate the reduction in pressure in the chamber 15. An apertured plate 23 in the high-pressure chamber 4 prevents the diaphragm 5 from being pushed down so far as to close the water passage 6. In another form, a by-pass leading from the high pressure chamber below the diaphragm to the hot-water outlet passage is opened by a valve connected to the delivery valve, when the latter is moved towards its closed position.

Title: Improvements in or relating to data storage systems
IPC: G11B5/004
Filed: 1958-07-15
Abstract: 895,725. Digital - data - storage apparatus. WESTERN ELECTRIC CO. Inc. July 15, 1958 [July 18, 1957], No. 22653/58. Class 106 (1). A data storage system comprises a rotatable magnetic surface with at least one track having at least one group of equallyspaced storage cells, a plurality of magnetic heads equally spaced around the track so that the storage cells of at least one group register with the heads a plurality of times during each revolution, means including the heads for simultaneously sensing information recorded in the track, and logic means for translating the outputs of the sensing means. In the magnetic drum storage system shown, decimal digits are each represented by a 4-bit quinary portion and a 4-bit binary portion recorded on tracks 10, 11, Fig. 1, respectively. The 8 bits are so spaced around the tracks that they can be read simultaneously by heads 15 and 16, and the digit code is such that significance is attached only to the total number, and not to the relative position, of " 1's " in each 4-bit portion, the total number of " 1's " in the quinary and binary portions together being always odd for checking purposes. The outputs of read amplifiers 17, Fig. 2, associated with heads 15, are connected to successive levels of a quinary-code-translating tree circuit comprising AND and inhibit circuits 20 and 21, the circuits being controlled at the first level by clock pulses from source 30 which may be a further drum track. The tree circuit output lines 36-40 correspond to 0-4 " 1's " respectively and are connected to corresponding inputs of a utilization circuit 58 (not described in detail). The outputs of the amplifiers 17 associated with heads 16 are connected to a similar binary-codetranslating circuit whose output lines 48-51 correspond to 1-4 " 1's " respectively. Since 1 or 2 " 1's " corresponds to a binary portion of value 0 and 3 or 4 " 1's " to a binary portion of value 5 the lines are connected in pairs through OR circuits 53 to the appropriate inputs of circuit 58. Lines 36-40 and 48-51 are connected also to a check circuit including OR circuits 65-68 and AND circuits 62 and 63 which apply an O.K. signal to circuit 58 over lead 64 if the total number of "1's " is odd. Information may be recorded simultaneously by heads 15 and 16 the bits being supplied from a further translating circuit (not described in detail) to write amplifiers 18. In a modification (Figs. 3 and 4, not shown), the binary and quinary portions are recorded on a single track having 8 associated heads, a second track providing gating signals for routing the information from the heads to the appropriate translating circuits. Reference is made to magnetic tapes, belts and discs, as well as drums.

Abstract: 682,818. Ignition magnetos. BENDIX AVIATION CORPORATION. Sept. 15, 1950 [Sept. 28, 1949], No. 22764/50. Class 35. The rotor 10 of a magneto has permanent magnets 35, 36, 37; pole-pieces 34 and a non- magnetic spacer 38 separating two of the polepieces arranged in such a manner that when the rotor is rotating the direction of the flux through the stator core 15 is reversed only twice during each revolution of the rotor. The stator and rotor pole-shoes are equally angularly spaced and when the magneto is used for a 2-cylinder engine two identical stators are used as shown in Fig. 1. The contacts of the make-and-break 17 are arranged to be opened by the cam 11 when the flux in the stator changes abruptly from a positive maximum to a negative maximum, i.e. between 180 and 270 degrees. Fig. 8 (not shown), and this occurs during the 90 degrees of the rotor movement during which the magnet 37, Fig. 6, leaves its shown position and its position is taken by the non-magnetic spacer 38, Fig. 7. The second flux reversal takes place during the next 90 degrees rotor movement and, although a voltage 43, Fig. 8 (not shown), may be generated in the stator coil, there is little likelihood of a spark to take place owing to the prevailing condition of the gases at that instant in the cylinder of the engine.

A thermal switch, particularly for an electric hand iron, comprises a bimetallic strip 23 clamped at one end, a substantially rigid member 25 connected at one end to the free end of the bimetallic strip and resting at its other end on a rotatable cam 28, and a rigid insulating member 34 to transmit the motion of the member 25 to a switch of the trifurcated spring blade type. Lateral displacement of the member 25, which may be of stainless steel, is prevented by a tongue 24 at the end of the bimetal strip engaging in an aperture in the end of the member 25, which at its other end has arms engaging round the adjusting spindle '29 for the cam 28. The member 34 which may be a glass rod is seated at its lower end in a thimble 32 carried in an aperture 53 in the member 25 and at its upper end passes through an aperture 50 to engage the central tension limb of the switch blade 42. As the temperature rises, the free end of the bimetallic strip 23 curls upwards causing the member 25 to pivot about its point of engagement with the adjusting cam 28, so raising the rod 34 to cause the blade 42 to move over its dead centre position to open contacts 44, 45. The operating temperature of the switch is adjusted by rotating the cam 28 by means of a knob 31 on the spindle 29, the cam surface changing in height in a direction at right angles to the plane of the bimetallic strip. The provisional specification states that the spindle 27 may be axially adjustable to permit initial calibration of the switch to be made.
