Filed: 1922-10-14
Abstract: 209,807. Batten, J. D. Oct. 14, 1922. Propelling-The downstroke of the wings of a flapping machine is effected by the pilot extending his legs with the assistance of rubber and helical springs acting on the wings to move them in the same direction, the upstroke taking place without anv muscular or mechanical assistance. The Figure shows one form of the apparatus in which wing-spars i, pivoted to the main frame at h, have stayed brackets k at their inner ends acted upon by opposed tension springs n and compression springs o. Rubber springs r also act upon the spars in the same sense. The inner ends of the springs o, n bear against a fixed plate q. A rod p passing through the compression springs o slides in slots in the ends of the brackets k. A spar s, connected to the wing spars i by rods or cables w and to the rear part of the frame by links t, is pressed down during the downstroke by the legs of the pilot, who is provided with a sling seat f and shoulder straps g secured to the frame. According to the Provisional Specification, the inner ends of the wing spars are extended inwards and are acted upon by vertical tension and compression springs placed respectively above and below the spars.

Title: Improvements in or relating to vacuum electric tube devices
IPC: H01J9/04
Filed: 1926-11-09
Abstract: 285,538. Robinson, E. Y., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 9, 1926. Vacuum tubes.-Filament cathodes are, coated with oxide, or with one or more substances subsequently converted to oxides, after mounting the filament on its supports but before the other electrodes are associated with the pinch or seal or, if such is used, with a cathode framework such as is described in Specifications 285,536 and 285,537. A fine filament with a sheath of another metal applied, for example, by the Wollaston process may have the sheath removed, after mounting the filament on its supports or framework, by evaporation or solution : a silver sheath on a platinum-iridium filament may be dissolved in dilute nitric acid or removed by heating in a vacuum oven or by passing current through the filament in a vacuum. After removal of the sheath, a coating of oxide, carbonate or alkaline earth metal is applied, the metal being converted to oxide before or after mounting the framework on the foot or after sealing the electrodes into the envelope. Oxide coatings may be converted to carbonates before inserting into the valve. The electrolytic process described in Specification 221,851 may be used, a coating of metal or, if water is added to the electrolyte, of oxide being formed. The framework may be protected during coating by paraffin wax. The coating may alternatively be applied by repeated dipping in an aqueous solution of barium and strontium nitrate, the filament being heated by current in carbon dioxide after each dipping to form carbonates. In further modifications, coatings of a suspension or paint of barium or strontium carbonates in water or alcohol are applied and heated in carbon dioxide. Specifications 245,146, 245,147, 272,549, and 275,542 also are referred to. The Provisional Specification describes the removal of a thin metallic sheath after the oxide coating is applied, also coatings sprayed on to the filament.

Title: Temperature sensitive devices
Inventor: PINCKAERS BALTHASAR H
IPC: G05D23/30
Filed: 1970-06-11
Abstract: 1279183 Automatic temperature control HONEYWELL Ltd 11 June 1970 [18 June 1969] 28245/70 Heading G3R A temperature sensing unit 10 Fig. 1 comprising a thermistor 20 includes an anticipatory heater in heat exchange relationship with the thermistor and having a linear energizing current/power dissipation characteristic. In a space heating arrangement shown the thermistor 20 responds to Room temp. and the heater is a transistor 26. Alternatively it may be a Zener diode Fig.2 (not shown). The thermistor is connected in a bridge unit which produces an output at terminal 12 when the sensed temp. deviates from a desired value. The unbalance output is detected by a level detecting and sequencing unit 35 which sequentially turns ON or turns OFF thyristors 40 to control four electric heater units (not shown) via heater relays 17, depending upon whether the room temp. is to be raised or lowered. In addition, the unit 35 operates sequentially the switches 50, simultaneously with corresponding thyristors. Closure of a switch 50 causes conduction of a transistor 60 which in turn passes collector/emitter current through Tr26. Each switch closed increases this current and hence the heat output of the anticipatory heater. This heat rise is sensed by thermistor 20 and thus, if the space temp. is increasing, the temp. signal at 12 drops more rapidly than if it were representative of the rising space temp alone. This causes the detector 35 to turn OFF an SCR (in a known manner not described) and open a corresponding switch 50 at an earlier moment than otherwise. The heat output of the transistor 26 is a linear function of the amount of heat supplied by the heating system by virtue of its bias arrangement which maintains a substantially constant collector/emitter voltage regardless of its collector emitter current, so that its power dissipation varies linearly with said current. The level detector 35 may alternatively turn OFF all the thyristors 40 and open all of the switches 50 simultaneously.

Title: Door locks
IPC: E05B9/08
Filed: 1947-10-27
Abstract: 646,388. Locks. GATE-WAY, Inc. Oct. 27, 1947, No. 28654. Convention date, Jan. 29. [Class 44] In a door lock wherein a key-controlled cylinder lock is mounted in one of the door knobs 10 and a leaf spring 29 attached to the cylinder 27 of the lock engages with the interior of the door knob for retaining the cylinder in the door knob, the spring is accessible through the knob shank and may be moved laterally to permit removal of the cylinder. The leaf spring 29 is corrugated at 30 and rigidly attached to the cylinder 27 by engaging a recess therein. A tang struck out of the spring presents an outwardly facing shoulder which engages a shoulder 33 on the interior of the knob 10, the spring being biassed outwardly to retain the shoulders in engagement. The cylinder 27 is prevented from tilting by bearing against a rib 34 formed on the interior of the knob opposite the spring 29. A half round sleeve 15 extends into the shanks of the knobs 10,11, and has its edges abutting shoulders in the latter so that rotation of either knob rotates the sleeve and effects retraction of the latch bolt 17 by known means housed within a casing 18. Within the sleeve 15 is a spindle 24 that may be rotated either by a thumb key 25 projecting from knob 11 or by the plug 26 of the key-controlled cylinder lock, the plug having pins 28 to engage the end of the spindle. A lock slide retainer 19 rigid with the knob 10 and housed within a stem rosette 12 on the outside of the door has a lock slide 20 laterally slidable within it. The slide 20 has a recessed end engageable with a rib on the rosette 12, the slide being moved into this position to prevent the knob 10, and consequently the knob 11 from being rotated, by means of a plug 23 rigid with the rotary spindle 24. To remove the lock cylinder 27 the screws 14 securing a plain rosette 13 to the inner face of the door are removed together with the rosette, knob 11, and spindle 24. A screw driver inserted through the spindle hole may now prise the spring 29 inwards and allow removal of the cylinder 27.

Title: Improvements in electric power-factor indicators
IPC: G01R11/48
Filed: 1925-11-13
Abstract: 243,008. M³ller, H. Nov. 13, 1924, [Convention date]. Power-factors, measuring.-An apparatus for indicating when the power-factor of a plant falls to a predetermined minimum value consists of a transformer having a primary winding P, connected across the voltage of the network E, and a secondary winding S connected to a lamp L. An electromagnet M is excited from a voltage e obtained from the consumption circuit and proportional to the current in the line J. The magnetic circuit of the electromagnet M is closed through that part of the core of the transformer carrying the secondary winding S. The parts are so proportioned that the flux due to the primary winding is counteracted by that due to the magnet M to such an extent that the lamp L does not light unless the power-factor is of or below the minimum value. The core of the electromagnet M is arranged to work at saturation value and the exciting coil is arranged at the end remote from the transformer so that when the voltage e rises the leakage rises and the auxiliary flux passing into the transformer remains constant in value. In order to adjust the value of the power-factor at which the apparatus operates, the distance of the magnet M from the transformer, or the ratio of transformation, or the reluctance of the transformer may be varied. The exciting winding may be connected across a resistance with a negative temperature coefficient. A bell &c. may be connected in series with the lamp L.

In a route search arrangement in which a circuit simulating the track layout is provided with a number of columns and rows of control units each associated with a section of the track layout and each unit is provided with a routesearch input terminal, first and second priority output terminals and means for blocking the passage of a search signal therethrough when the associated track section is occupied or forms part of a previously set-up route, a route search signal originating in the control unit associated with the required entry point to a route is passed from unit to unit of a row via the first priority terminal until the control unit associated with the required exit point is reached or the end of the row or a blocked control unit is reached when the search signal is applied to the second priority output terminal of the next preceding unit in turn carrying search current until access is obtained to an adjacent row whereafter the process is repeated until the signal reaches the unit associated with the required exit point. In the arrangement the numbered track sections, Fig. 2, are represented by the control units, Fig. 3, connected in accordance with the track layout. Each unit, e.g. unit 23, is provided with a search signal input terminal 22- 23, an input 23 which may carry a blocking signal from the associated track equipment, a first priority output terminal 231 connected to the adjacent unit 24 in its row and a second priority output terminal 232 connected in accordance with the track layout to unit 34 in an adjacent row. The units also include To and From buttons for defining the ends of a route. Assume a route from unit 21 to unit 18, the search signal will be passed from unit 21 via the first priority connections along the row to unit 28, where since it cannot proceed further it is reverted back to unit 27 and applied to its second priority output terminal 272. Since the signal cannot proceed via this terminal it is again reverted back to unit 26 which via its second priority terminal routes the signal to unit 17 and via the first priority terminal of this unit to unit 18. A control of programme unit CP which detects the operation of the To and From buttons defining the route initiates the search operation with the assistance of register stages K0-K8.
