Abstract: A method and apparatus provide for the production of low kappa number (e.g. below 20) kraft paper pulp, and a low viscosity black liquor which is easily transported to a recovery or disposal stage. Comminuted cellulosic fibrous material is steamed (at 11), passed to a treatment vessel (13, 113, 213), and then introduced into the top of a continuous digester (24, 124, 224). Black liquor is withdrawn from the digester (at 32, 132, 232) and heated (in 35, 135, 235) about 20-40 degrees C above cooking temperature (e. g. to about 170 degrees C), and then introduced into contact with the material in the treatment vessel. After the material is treated with the black liquor, it is withdrawn from the treatment vessel (at 17, 117, 217), and passed to the recovery or disposal stage. White liquor may be introduced into the treatment vessel (at 18, 118, 218) after black liquor withdrawal, after passing in heat exchange relationship (119, 219) with liquid recirculated from an impregnation vessel to a high pressure feeder (21, 121, 221). Alkali may be added to the black liquor withdrawn from the digester (at 34), prior to heating, and after heating it may be passed to a reaction vessel (36, 136, 236). <IMAGE>

Title: Improvements in or relating to holders and dispensers for paper
Inventor: LITCHFIELD ANTHONY FRANK
IPC: A47K10/36
Filed: 1955-01-20
Abstract: 794,825. Coin-freed vending apparatus. LITCHFIELD, A. F. April 20, 1956 [June 20, 1955], No. 1692/55. Class 27 Coin-freed apparatus for dispensing lengths of paper, such as toilet paper or absorbent hand towels, from a perforated or scored roll comprises a shaft 14 for receiving the roll, discs 23 of resilient material carried on pivoted links 23a, and pressing the paper against a ribbed metering roller 18, a lead-out 20 having slots through which the roller 18 and discs 23 extend and a control boss 28 geared to the metering roller and having two diametrically opposite grooves 29, 30 co-operating with a U-shaped rocker arm 32. When a coin is inserted in a slot 34, it bears against a roller 36 at one end of the slot and depresses a roller 33 on the rocker arm, thus releasing the further end of the arm from the groove 30 and causing a pivoted pawl 35 to move to the end of the other groove 29 and rotate the control boss sufficiently to ensure that the rocker arm does not re-engage with the groove 30 when the coin drops between the rollers 33, 36. With the control boss freed, a knob on the shaft 24 of the control boss can be rotated to turn the metering roller and feed the paper until the rocker arm again engages the groove 30. A ratchet catch 31a prevents opposite rotation. Rotation of the shaft 24 to effect an initial supply of paper may be effected by connecting it to a coin-freed door lock. A light spring may bear on the roll of paper to prevent over-run and an "empty" indicator 39 is provided on a lever 40 bearing on the paper. The Provisional Specification also describes a pair of rubber-faced bars which grip the paper between them and, on coin release, are moved forward to bring the free end of the paper to an accessible position, after which the bars separate for a time to allow the paper to be withdrawn.

Title: Thermoelectric apparatus and method
Inventor: FORDHAM GLENN WAYNE
IPC: G01K1/02
Filed: 1962-01-17
Abstract: 978,317. Measuring temperature electrically. ATLANTIC REFINING CO. Jan. 17, 1962, No. 1696/62. Heading G1N. The difference in temperature at two depths in a borehole is measured by two thermocouples connected in series, the digital voltage being measured by a potentiometric arrangement which is calibrated by a standard cell with the thermocouples replaced by their equivalent resistance. As shown (Fig. 1), thermojunctions 1, 7 in a borehole 11 are interconnected by a construction wire 5, and the difference signal voltage taken by copper lead wires 3, 9 via a unit 17 and balancing potentiometer 19 to a chopper amplifier 27. Unit 17 incorporate bridge ratio arms 49, 51 (Fig. 2) and a battery 55 to enable a 3-decode variable resistance 75, 79, 83 to be adjusted to the equivalent resistance of the thermocouples, the chopper amplifier 27 acting as the unbalance detector for the bridge, when the selector switch 59 is in the balance position. Unit 19 contains a standard cell 85 of known EMF, used to calibrate the amplifier 27. With selector switch 59 in the calibrate position, the thermocouples are replaced by their equivalent resistance in unit 17, and a backing off voltage is adjusted inside amplifier 27 until the output signal is zero. This neutralises spurious voltages in the circuit. The standard cell circuit is then completed through a 1 megohm resistor 91 in series with a standard resistor 87 selected to give a 1 microvolt drop across it. This is fed with the amplifier 27 and its gain adjusted to produce full scale deflection on its meter. Having thus calibrated the amplifier 27, switch 59 is turned to the head position, and the thermocouple output is balanced partly by sliders 89, 93, 97, which indicate the digital part of the temperature voltage signal, the meter of amplifier 27 indicating the fractional part of the voltage signal. The Specification describes the precautions necessary to maintain high accuracy. The apparatus is used in the geophysical exploration for petroleum deposits.

Abstract: 1387571 Fluid heating systems; central heating systems ASW APPARATENFABRIEK NV 15 Jan 1973 [20 Jan 1972] 1943/73 Headings F4A and F4U A fluid heating system comprises a burner 1 and associated heat exchanger 2 which define a boiler through which a liquid heating medium is circulated by pump 10, a valve 6 which can direct hot medium either to space heaters (not shown), or to an insulated indirect domestic water heater 7, a boiler thermostat 5 arranged between the boiler and the valve 6 to turn off the burner when the medium exceeds a predetermined maximum temperature of about 90 C., and a further thermostat 8 having a sensing element 11 disposed in water piping of the heater 7; the heater thermostat 8 operating the valve 6 to direct heating medium through the heater 7 when the water temperature falls to a first temperature (about 55 C.), and to divert flow through the space heaters when the water temperature has risen to a second temperature (about 65 C.), and the sensing element 11 being disposed at such a distance from the inlet of the heater 7 that when the flow rate past it is at least 0À3 litres/min. (preferably not less than 1À25 litres/min.), the temperature sensed is the said first temperature. Fig. 2, shows the water heater 7 in more detail; heating medium entering at 15 and leaving at 16 and water piping being arranged in two helical coils 12, 13 on each side of a baffle 14. The thermostat sensor 11 is disposed in a straight transition portion of pipe between the two coils. A control member 9, such as a regulating screw for instance, is provided to control the supply of domestic water to heater 7. The arrangement shown is gas-fired and burner control is effected by operation of gas supply valve 23. An additional sensor 3 acts to turn of the gas supply via the valve 23 should the temperature of the heating medium rise to a dangerous level. Fig. 3, shows the control circuit of the system in which a transformer/rectifier 20, 21 supplies power to the valve 6, the burner control valve 23, and a relay 17 which operates the pump 10. A 'summer-winter' switch 18 is provided and when this is in the 'summer' position shown the thermostat 8 when closed (i.e. when the first temperature is sensed), operates valve 6, pump 10 (via relay 17), and (subject to thermostat 5), the burner valve 23. In the 'winter' position of the switch 18 (i.e. when this switch is closed), the pump 10 is continuously on and the burner valve 23 receives power via a indoor or outdoor thermostat 19 independently of thermostat 8. However, the arrangement may be such that (as in known devices), the pump may operate in the winter position only if the heater 7 or the space heaters require heating fluid.
