Title: Apparatus for controlling the direction of the draught in an air conditioning or ventilating system
IPC: F24F11/00
Filed: 1926-05-27
Abstract: 274,242. Groom, S. L., and Carrier Engineering Co., Ltd. May 27, 1926. Controlling ventilation ; valves and valve apparatus, actuating; forced ventilation; ventilating pipes, arrangements of.- Apparatus for controlling the direction of draught in a theatre or other enclosure supplied with heated, cooled or otherwise treated air, comprises a fan &c. 6 drawing its supply from damper-controlled ducts, a main discharge duct 5 extending from the fan to the enclosure, and a return duct 16 running from the bottom levels of the enclosure to .the fan, and means are provided for actuating dampers for cutting off the normal supplies to the fan, connecting an auxiliary duct 11 with the fan, and delivering therefrom to a bye-pass opening to the atmosphere. The auxiliary duct 11 is associated with exhaust openings 18, 19 at the upper levels of the enclosure, and communicates with the fan by means of a duct 14 controlled by a damper D. Fresh air is delivered to the fan through a damper A, air extracted from the enclosure through the duct 16 is delivered through a damper B, and extracted air may also be delivered through a damper C. Normally air is delivered to the fan through one or more of the dampers A, B, C and is discharged into the upper part of the enclosure through the duct 5. A damper E is provided in the main duct 5, and a damper F in a chimney 4 fitted on the said duct 5. To change the direction of draught, the dampers A, B, C, E are closed and the dampers D, E are opened. The fan then draws its supply from the exhaust openings 18, 19 through the ducts 11, 14, and delivers it to the chimney through the main duct 5. A pneumatic or other system is provided whereby the dampers may be appropriately operated. Fig. 3 shows one method of operating a valve, wherein the damper B is opened when air is admitted to a space beneath a flexible diaphragm 24. If a valve 32 in the pipe line 2 be opened, air escapes from the space 23, and the disc 25 and rod 26 fall, thereby closing the damper. The valve 32 is operated by hand or by means of a make and break switch in a circuit including a solenoid surrounding the extended spindle 31 of the valve 32. The air for each of the systems operating the valves is supplied from a reservoir 1 through non-return valves. The dampers E, F are interconnected so that the opening of one causes the other to close. The lowering of a safety curtain may be arranged to operate one or more switches to reverse automatically the direction of draught. An alarm in the form of a buzzer, or pilot lamp, or an illuminated sign, may be arranged in the manager's room. Specification 273,069 is referred to.

Title: Method and apparatus for continuous casting of metal ingots
IPC: B22D11/14
Filed: 1972-03-22
Abstract: 1388022 Continuous casting ALCAN RESEARCH & DEVELOPMENT Ltd 22 March 1972 [22 March 1971 (2)] 13505/72 Heading B3F A starting dummy 18 for initially closing a mould 10 has at least one drain passage, e.g. a duct 32, which is opened automatically after a short downward movement of the dummy, to release water or its vapour accumulated from cooling water directed (as from a slit 22) on to the emerging casting 12. As shown a loose plug 38, Fig. 4, is placed at the end of duct 32 to close it. As the metal 12 solidifies around it and contracts with cooling as the dummy and metal are lowered, it is lifted by the upward contraction and water which collect in the resulting gap 40 can drain away. Pure or alloykd A1 is suppliedthrough a dip tube 28 controlled by a floating baffle 30. In another embodiment, Figs. 5-7 (not shown), the dummy has two upper side portions (45) supported on inclined surfaces of the base (44) of the dummy so as to tend to slide down and outward laterally of the dummy away from a fixed central rib which separates them. For insertion into the mould outlet, however, the side portions are closed up to the rib and together with it form an initial mould-base. As the dummy is lowered, the cooling casting base contracts away from the tops of the side portions (45) and they are released to slide outwards down to stops (54) so that water draingaps (48) form either side of the rib. The moving portions (45) are held against the dummy rib by the mould wall or by spring-loaded arms (58) when in the mould but clear these for release when the dummy is lowered.

Title: Method and means for producing woven reed articles
IPC: D03D41/00
Filed: 1920-05-19
Abstract: 167,861. Lloyd, M. B. May 19, 1920. Wickerwork. - Articles of wickerwork made from woven natural reed, fibre reed, or composite materials are constructed by mechanically pressing flat sheets of the woven reed-fabric onto skeleton frameworks so that they conform to the curved shapes of the frameworks, and finally securing the sheets to the frameworks. A hood for a baby-carriage is shown. The woven fabric, which is shown as tubular, but need not be, is cut to the shape shown in Fig. 3, the stakes 3 at the sides being turned down at 3<11> to confine the filler strands, metal binding-strips 5 being also secured to the ends to prevent unravelling. The hood skeleton or frame consists of U-shaped members 9, 10, &c., Fig. 6, with spacing members 12, radiating from central points, at which are fixture members 11 resigned to engage pivots on the baby-carriage; the woven sheet is stretched across the frame and secured to it by a number of brads 13. The covered skeleton is now placed on a former 32, Fig. 7<A> and the curvature from front to back obtained by pressing plates 14, 15, Fig. 7, against the fabric by means of cam-members 16, 17, pivoted in arms 18, 19, carried by a frame 20. The lateral curvature is obtained by means of two curved side clamping frames 23 hooked on to the arms 18, 19, and having depending members 26, provided with projecting pins 28. Leverage mechanism, comprising arms 31, Fig 7<A>, and handle parts 30, depending from the former, is adapted to engage the pins 28, hook parts 29 also engaging the hood fixture members 11, so that on movement of the handles 30 both the hood skeleton and the covering fabric are drawn downwardly and inwardly together, the fabric being thus strained to conform to the frame. The surplus edges of the fabric are now folded around and secured to the frame so that the clamping members can be removed. The ends of the binding- strips 5 are bent over the frame and secured by brads td the fabric. Additional binding-strips, held in place by brads, may be secured over the inturned ragged edges of the hood to clamp them to the framework. The invention is not applicable to fabrics of a different structure such as cane-work.

Title: An improved arrangement for the measurement of electrical impedance
IPC: G01R27/02
Filed: 1940-09-09
Abstract: 542,050. Inductance and capacitance measurements ; condensers. BRITISH INSULATED CABLES, Ltd., and QUAYLE, J. C. Sept. 9, 1940, No. 14016. [Class 37] A Q-meter comprises inductance and capacitance in series adjusted to resonance, in which the inductance and capacitance elements 10, 11 and 14, 15, Fig. 5, are each in halves arranged symmetrically relative to an earthed connection so that an unearthed or centrally earthed external impedance to be tested can be inserted between the halves of the appropriate impedance element of the meter and the magnified voltage is rectified by diode valves 19, 20 each connected across one half of one of the impedances. The test voltage is applied from a coaxial line to terminals 3, 4, Fig. 5, across a resistance 5 of low value, the current strength being indicated by a meter 8 connected to a thermo-couple 9. The capacitive elements 14, 15 are ganged variable condensers connected between the ends of the inductance elements and terminals 16, 17 for the test impedance, shown as a twin cable. A plug 18 is provided for short-circuiting the terminals 16, 17. The anodes of rectifiers 19, 20 are connected by a high resistance 61, 62 between the centre point of which and earth a voltmeter 74 is connected, either directly or through an amplifier. To measure the magnification of a balanced twin coil, injected voltage is deduced from a measurement of the input current on the meter 8. The resonant voltage developed across the coils is measured by the voltmeter 74, the ratio of this to the injected voltage giving the magnification. For components other than coils the change of magnification of the tuned circuit is measured when the component is connected to it. Capacitances to be measured are connected across the terminals 12, 13, the plug 18 being left in. Inductances are connected in series with the terminals 16, 17, the plug 18 being removed. The magnitude of balanced inductances and capacitances is measured by tuning the circuit to resonance and calculating the required value from the known values of supply frequency and tuning capacitance. Constructional details.-The condensers 14, 15 are supported on brackets 26, 27, Fig. 1, which carry the rotor bearings, serve as connections and also carry an insulating-plate provided with sockets for the connection of the inductive elements 10, 11. The ganged rotors are driven via reducing gearing 38 by a knob 39. Terminals 16, 17 for the element to be tested are carried on metal brackets 42, 44 provided on the condenser stators and may be connected together by plug 18. The input connections from the coaxial line 7 are made by strips 53, 54 to which resistor 5 is soldered, and the heater and thermocouple 9 also are carried by this assembly. The remaining elements are carried by a sub-base 31.
