Title: Boiler condensate neutralising unit
Inventor: DAY PAUL
IPC: C02F1/66
Filed: 2009-11-18
Abstract: A neutralising unit apparatus suitable for attachment to the condensate outlet of a condensing boiler comprises a housing 1 which has an inlet 7 leading into a first chamber 2, a second chamber (3, fig.2) leading to an outlet 9, where the second chamber contains a solid neutralising agent 15 which may be in particulate form. The neutralising unit is adapted so that, in normal use, condensate from the boiler flows through the inlet into the first chamber, then upwards through the solid neutralising agent in the second chamber, and then out through the outlet. Preferably, the unit is provided with an escape passage 11 at or near the top of a separating wall between the first and second chambers so that in the event of blockage of the unit caused by any restriction to condensate flow in either the first or second chamber, the condensate can pass through the escape passage and then discharge from the outlet of the second chamber without having passed through the neutralising agent. In use, the apparatus is designed to provide treatment of an acidic aqueous solution, and particularly the condensate that is generated as a by-product of a central heating condensing boiler.

Patent GB-1175474-A (GB)
Title: Recorder Apparatus
IPC: G05D23/19
Filed: 1968-03-01
Abstract: 1,175,474. Rectifying. BLH ELECTRONICS Inc. 1 March, 1968 [14 April, 1967], No. 10164/68. Heading H2F. [Also in Division G1] The invention relates to a method of and apparatus for producing records on a thermallyresponsive medium 4 co-operating with a movable stylus including an electric heater, in which the supply of power to the heater is controlled in accordance with signals produced to characterize the frequency and amplitude of the stylus movements. In a recorder, such as that described in Specification 1,136,113, a stylus motor 19 receives electrical input signals, having variable frequencies and amplitudes, and drives across the medium 4 a stylus including dis-similar metal elements 11a, 11b. Corresponding signals are also developed across a resistance 52 and passed on as unidirectional half-cycles to an R-C integrator network through the action of a half-wave rectifying diode 53. The effective time of the integrator network is selected so that a capacitor 55 will charge rapidly through resistance 56 but will discharge slowly through associated relatively high impedance circuitry. Amplified signals appearing at a point 49 control the heating power to the stylus which is supplied by a source 41 coupled into a rectifier-regulator control unit 42 by way of a transformer 43, the centre tap of its secondary being connected to ground and to the stylus lead 14. The emitters of semi-conductor devices 45, 46 are coupled to the ends of the secondary winding, their collectors are both connected to the stylus lead 14 and bias resistances 47 48 are associated with their bases. The unit 42 will always deliver at least a predetermined minimum supply of power to the heater but, when the bias voltage at the point 49 is automatically varied to increase the conduction times of the devices 45, 46, the heating power delivered to the stylus will increase to raise its temperature as warranted by the frequency and amplitude of the signals determining the control voltage at the point 49 and being simultaneously recorded. Very low frequency variations in the input signal are blocked by a coupling capacitor 51 and very high frequency, low amplitude variations are by-passed by a capacitor 54. Within these limits, increases in stylus heating are substantially proportional to the frequency and amplitude of stylus movement, thus both scorching and inadequate recording temperatures are avoided. The invention may be applied to recorders of non-electrical variables by translating the variables into corresponding electrical variations.

Title: Improvements in or relating to the control of the thickness of material
Inventor: SIMS RAYMOND BERNARD
IPC: B21B37/18
Filed: 1959-03-24
Abstract: 945,058. Automatic thickness control. DAVY & UNITED INSTRUMENTS Ltd. March 10, 1960 [March 24, 1959], No. 10230/59. Heading G3R. Thickness of material emerging from a mill is automatically maintained at a desired value under the control of two devices measuring thickness of the material emerging, one having short term accuracy and being located near the mill gap and the other having long term accuracy and being further from the gap. As shown, strip 21 is' unwound from a reel 22, passes between strip mill rolls 15, 16 and is wound up on a reel 23 driven by a motor 24. Variations in the thickness of strip emerging from the mill are detected by a robust thickness gauge 26 (e.g. a radiation type gauge), having short term stability, the output of which is applied, in opposition with the voltage from a reference potentiometer 32, to control a follow-up type electric servomotor 47 through a modulator 44 and an amplifier 45. Servomotor 47 adjusts a two-way switch 50 to correct the thickness by controlling a reversible electric screwdown motor 20 adjusting the mill gap, and/or a circuit 25 adjusting the speed of wind-up motor 24. If the correction is by both methods control of the screw-down motor takes over when control of wind-up motor speed reaches a predetermined limit. To increase accuracy, the output of a contact micrometer type thickness gauge 27, located further from the mill gap and having long term stability, is compared with the output of gauge 26, any difference being applied to a modulator 33 and causing a follow-up type electric servomotor 37 to adjust a rheostat 41 so that an integrated error signal is applied as a correction to modulator 44.

IPC: H02P1/16
Abstract: 106,898. Electric Control, Ltd., and Ellefsen, O. July 28, 1916. Master control systems. - In a control system in which the closure of the accelerating-contactors is controlled by series relays, the circuit of each contactor after the first is completed by a contact mechanically connected to the previously operated contactor and a contact mechanically connected to the core of its associated series relays. The accelerating-contactors D', D<2>, D<3>, Fig. 1, are operated by coils C<1>, C<2>, C<3>, and the line contactor D is operated by a coil C. As a contactor closes it operates a lever F<1>, F<2> &c. and moves the core of a series relay into its coil where it is held until the motor current drops to a value which permits the cutting out of resistance. The combination of contactor and relay is shown in Fig. 3. The spring contact L<1> of the contactor D' is operated by the coil C' and a rod on the contact arm carries a contact G' and a cam J. This cam engages the lever F<2> as the contactor closes and operates the core of the relay A<2>. When the motor current drops sufficiently, the relay core is pulled back by a spring or by gravity and the contact G on the relay lever engages the contact G<1> and completes the actuating-circuit for the next contactor. The relay coils may act as blow-out coils, or additional blow-out coils may be provided.
