Title: Indicator for the condition of a battery of an electronic calculator or timepiece
IPC: G01R19/165
Filed: 1974-04-30
Abstract: 1463423 Measuring voltage; testing batteries EBAUCHES SA 30 April 1974 [10 May 1973]  18821/74 Heading G1U The condition of a battery, indicated by its terminal voltage, is measured by comparing the battery voltage with a stable reference voltage generated by a constant current device and actuating a passive non-light-emitting display when the battery voltage falls below the reference voltage. Zener diode ZE and constant current source I produce the reference voltage from the battery voltage Up. If the baseemitter voltages of T1, T2, T3 are equal at U BE , as long as U p -ZE > U BE , T3 will conduct, shorting current flow through an electrochromatic or liquid crystal display A. When the battery voltage falls  below U BE  + ZE, T3 turns off and current flows through A which becomes progressively opaque if electrochromatic, or instantly so if a liquid crystal. Since A requires very little current, the system is useful for low voltage batteries i.e. 1-3 volts as used for example in wristwatches. Further modifications include an arrangement for controlled colouration and dimming rates of the display Fig. 4 (not shown); a manual or automatic periodic monitor Fig. 5 (not shown) and an arrangement for temperature compensation in the comparison circuit Fig. 6 (not shown). A circuit suitable for an integrated package is given Fig. 7 (not shown) which may be coupled with an identical circuit to monitor two batteries with one display.

Abstract: 769,905. Water-tube steam boilers. FOSTER WHEELER, Ltd. June 30, 1955 [June 30, 1954], No. 18935/55. Class 123(2) In a water-tube boiler having a furnace 10 which is fired, maybe under pressure, by burners 34 and which is lined with steam generating tubes 12, 14, 16 extending between headers 46, 48, 50 and a steam and water drum 40 respectively disposed below the furnace floor 38 and above its roof 42 and wherein combustion gases leave the furnace through an opening 18 and flow downwardly in a pass 20 locating a superheater 22, a reheater 24, a boiler convection section 26 and an economizer .32, the inlet and outlet headers of which are all disposed outside the rear wall 30 of the pass, the points at which the steam generating &c. tubes pass through the setting roof, floor and walls are enclosed by air-tight casings 72, 74, 76, 78 in each of which an air pressure exceeding that prevailing within the setting is maintained in order to prevent leakage of combustion gas through the tube openings in the setting roof, &c., into the boiler room. The air is supplied by a pump 80 which delivers into a manifold 82 whence conduits 84, 86, 88, 90 lead to the respective casings each of which is provided with a vent pipe 92. 94, 96, 98 respectively, to atmosphere. The casing air pressure is automatically maintained above the setting gas pressure, which varies with boiler load, by identical regulator devices 100, 130, 140, 150. The device 100, Fig. 2, consists of a housing 102 divided by a diaphragm 104 into an upper and a lower chamber respectively connected by tubes 106, 108 to the casing and an adjacent part of the setting. The diaphragm operating rods 110, 112 actuate dampers 118, 120 respectively controlling the air flow in the air inlet pipe 84 to the casing and the vent pipe 92 therefrom so that as one damper opens, the other closes. The diaphragm is loaded by a spring 122 so that at its mid-position, i.e. its position of balance, the casing pressure exceeds the setting pressure by the amount of the spring pressure. If the setting pressure rises, for example, damper 118 opens and damper 120 closes until the pressure difference is restored by the increased air flow into and decreased discharge from the casing.

IPC: G07F15/04
Filed: 1954-06-30
Abstract: 782,170. Prepayment mechanism for gas or electricity meters. PARKINSON & COWAN, Ltd. June 30, 1955 [June 30, 1954], No. 19220/54. Class 27 Prepayment mechanism for a gas or electricity meter comprises a coin slot 3 in a rotatable barrel 8 having a hemispherically-concave knob 1, a cam drum 10 slidable on the barrel and pressed forward by a spring 30, a tongue 9 on the drum engaging in the rear end of the coin slot, a spring-loaded shutter 4 which closes the coin slot when the barrel is rotated, two fixed projections 22, 23, one of which is angularly adjustable by an official to vary the quantity of commodity supplied for a particular coin, and a cam recess 25-26 on the drum. When a coin is inserted and the knob rotated clockwise, a tag 6 and notch 7. Fig. 2, close the coin slot and. when the cam face 25 reaches the fixed projection 22, the cam drum can move forward so as to gauge the coin between the tongue 9 and the shutter 4. If the coin is of correct diameter. a dog 31 on the drum is in position to contact a dog 32 on a gear sector 29 connected to the quantity mechanism shaft 38 through a gear 35 and pawl and ratchet 37, 39 and to rotate it with the drum until the other end 26 of the cam slot engages the adjustable projection 23 and moves the drum back against the spring 30, thus releasing the coin through a slot in the drum into a coin box and releasing the dogs 31, 32 so that the gear sector 29 is returned to a stop 40 by a spring 34. The projection 23 is carried by a rotatably-mounted ring 16 adjustable by a pointer 20 which is covered, for example, by a locked cover and, by adjusting the ring counterclockwise from the fixed projection 22, the angle through the knob is turned before the cam surface 26 causes release of the coin is reduced and also, therefore, the quantity of commodity prepaid. The mechanism may be adapted for more than one coin and, for example, where a shilling and a sixpence are to be used, the projection 23 corresponds to a shilling and a second rotatably mounted ring 19 carries a projection 24 co-operating with a cam surface 27 positioned on the drum midway of the cam recess 25-26. Part of the circumference of the rings 16 and 19 is toothed and differential gearing 18a, 18b and 18c engaging these teeth and also teeth on a fixed ring 11 ensures that. when the shilling ring 16 is angularly adjusted, the sixpence ring 19 is moved by half that angular distance. The modified pivoted dog 31 shown in Fig. 5 has a projection 46 which contacts straight surfaces 47 or 48 on the barrel 8 if a shilling or a sixpence is inserted and is then in position to engage the dog 32 on the gear sector; if, however, there is no coin, the dog 31 clears the slot 60 in the dog 32 or, if the coin is intermediate in diameter between a shilling and a sixpence, the projection 46 rides on a raised surface 49 and the dog 41 pivots clear of the dog 32.

Title: Improvements in the production of metal oxides, especially iron oxides, by combustion of the corresponding metal carbonyls
Inventor: KLIPPEL HERMANN
IPC: C01B13/20
Filed: 1960-06-01
Abstract: In the production of metal oxides, particularly iron and nickel oxides, by the combustion of the corresponding carbonyls with air, the combustion is carried out in a chamber to which liquid water, which vapourises, is added.  The liquid water may be added to the metal carbonyl to be burned, or to the combustion air, or it may be added to the mixture of hot combustion gases and metal oxide during the combustion of the metal carbonyl, or liquid water may be added to all three.  The amount of water added should not be so great that condensation occurs in the separators for the oxide and gases.  This may be further guarded against either by slightly heating the apparatus in question or by passing heated air through it.  The product has an increased bulk density.
