Title: Improvements in priming and controlling syphon systems
Filed: 1939-05-06
Abstract: 528,414. Syphons. INCANDESCENT HEAT CO., Ltd., and HAVERLEY, R. W. May 6, 1939, No. 13565. [Class 69 (i)] In a syphon system for use with solutions of high freezing point, corrosive fluids &c. with an electrically actuated priming and controlling mechanism and means for cutting out the electric power when the syphon is in operation, the electric circuit includes electromagnetic means for positively operating the outlet valve of the syphon system. The syphon 5 is connected to a chamber 8 provided with a float 9 and a relief valve 11 and connected by pipe 13a to a vacuum pump 13 driven by a motor 14 ; the outlet leg has a valve 17 with a stem 17a passing through spring-loaded glands 17b. Through a starter push-button 20, an electromagnet 19 is energized to close a switch 18 and thereby, through electromagnet 21 and switch 22, energize an electromagnet 15 to close the valve 17 and also close the circuit through the motor 14 to cause evacuation of the chamber 8 and priming of the syphon ; when the rising liquid lifts the float, an arm 10 breaks the circuit through the electromagnet 21, and the switch 22 breaks the circuits through the motor 14, and electromagnet 15 and energizes a solenoid 16 to open the valve 17. When the valve 17 is fully opened, a pawl 24 on the valve stem 17a opens a switch contact 25 to break the mains circuit ; by means of a stop push-button 23, the mains circuit may be broken at any time. Alternatively, the relief valve 11 may be opened to stop the flow. In another form, the float 9 is replaced by an electrode, the rising liquid closing a circuit to cause operation of the switch 22. In a further form, the valve 17 is connected by parallel stems outside the syphon to a pivoted lever which is rocked by the electromagnets 15, 16.

Title: Systems for the reproduction of signalled intelligence
IPC: H04N1/00
Filed: 1945-05-30
Abstract: 591,339. Radio signalling. STANDARD TELEPHONES & CABLES, Ltd. May 30, 1945, No. 13623. Convention date, Feb. 20, 1943. [Class 40 (v)] Signals are passed through a normally blocked amplifier only if it is unblocked at the correct intervals by previously transmitted duplicate signals received at a predetermined time before and recorded for this purpose. As described, the output of receiver 10 is applied to the normally blocked amplifier 14 and also to the recording magnet 12 of a magnetic recorder 16. The second version of the signal is applied to the amplifier 14 simultaneously with unblocking signals derived from the pick-up magnet 20 which reproduces the first version of the signal at the appropriate time. When the two signals are the same, the amplifier 14 feeds the reproducer 24 with the desired output. The reproducer may be a cathode-ray tube producing facsimile characters on its screen. In a modification, Fig. 4 (not shown), the secrecy of the system is increased by oscillating the position of the pick-up coil 20 by means of gearing and a linkage from the recorder driving motor 18 synchronously with a variation of spacing of the two signals imposed at the transmitter. Alternative methods of recording are mentioned.

BUHNEN, [trading as SENCO HEINZ BUHNEN K.G.]. 23 March, 1967 [2 April, 1966], No. 13831/67. Heading B4C. A pneumatically-actuated tool for driving fasteners such as nails or staples comprises a working piston 2 movable in a cylinder 1 and controlled by an inlet valve 11 having a surface 19 acted upon by compressed air to maintain the valve closed and a larger operative surface 16 adapted to be acted upon by the air to open the valve when a trigger operated valve 12 is actuated. An air storage chamber 5 is provided which communicates with the interior of the cylinder 1 via ports 8 and with a housing 22 for a piston member 21 via a duct 25 and passages 26, 27. In operation, with the tool in the position shown, compressed air is fed via an inlet 9 into a reservoir 10 so as to act on the surface 19 of the valve 11, the space above the working piston 2 being exhausted to atmosphere via passages 13, 14. Upon actuation of the trigger 20 the valve 12 is actuated so as to allow the air to act on the surface 16 and thereby open the valve 11. Air then flows via passage 13 to act on the working piston to effect a working stroke. Towards the end of the stroke the air above the piston 2 passes through ports 8 and passages 25, 26, 27 into the housing 22 and moves the piston 21 downwardly so that via a tappet 23, it closes the valve 11. The piston 2 is then returned by air trapped in the chamber 5 and housing 22. A magnet 7 is provided for retaining the piston in its upper position.

[Class 83 (iv).] In an arc-welding apparatus having automatic means for feeding a flux coated electrode, a cutting tool in uninterrupted engagement with the coating is provided for making a longitudinal opening therein through which extends the means for supplying current to the electrode. A bracket 12 secured to a motordriven welding carriage carries a framework 11 supporting adjustable electrode feed rolls 9, 10, which are geared together and driven by a pinion 16 either direct from a variable speed motor or through a regulatable transmission from a constant speed motor, the variable speed motor or transmission being controlled by a characteristic of the welding arc. The rolls may be grooved and also corrugated or may have hard rubber treads. In a modification the roll 9 may be toothed for a purpose stated below. On the bracket is mounted a framework containing adjustable spring-pressed yokes 20, 21, respectively carrying a roll 18 for cutting the coating and pairs of conducting rolls 19. These rolls cooperate with backing rolls 23 mounted in screw-adjusted yokes. The cutting roll may be provided with guiding lips 41 and with a central knife-edged rib 42 for cutting the coating and the rolls 19 have lips and conducting ribs engaging the electrode through the slot in the coating. The backing rolls may be plain, grooved, or may be toothed so as to apply pressure directly to the electrode core when a toothed feed roll 9 is used. The slot may be helical in which case the current collectors and the electrode are rotatable relatively to each other. Cutting may be also effected by a knife-edged block, by a reciprocating saw or by a rotary saw or milling cutter 47, Fig. 9, in which latter case the electrode is fed through a sleeve 49. The conducting rolls may be replaced by adjustable spring-pressed shoes 50. A single roll or sliding contact may be used for effecting the cut and also conducting the current. The electrode may also be fed through the machine with the slot in the coating cut previously, the cutter in this case merely serving to guide the electrode. The mechanism described may serve as an attachment to a machine constructed for feeding bare electrodes. Specification 391,743 is referred to.

Abstract: 812,899. Fire-finishing glass surfaces. PILKINGTON BROS. Ltd., WYNNE, H. C., and YATES, D. J. May, 7, 1957 [May 9, 1956], No. 14477/56. Class 56. In the manufacture of face-plates of television cathode ray tubes and similar bowlshaped glass articles the outer surface of such plates or bowls is given a fire-finish. For this purpose each plate or bowl 14 is supported, convex face uppermost, on a carriage 4 which is reciprocated horizontally along rails 3 beneath a burner 17 that directs curtains of flame downwardly. To ensure uniform spacing of the burner from that portion of the curved surface being flamed the burner is raised and lowered, to follow the curvature, by cam-followers 29 associated therewith and engaging cam-slots 28 in parts 27 of the carriage 4. The sides of the plate or bowl parallel to the direction of movement of the carriage are simultaneously flamed by burners 53; these are slidably mounted in brackets 51 and are caused to approach or recede from one another to follow the side curvature by followers 55 engaging cam slots in brackets 58 on the carriage. The sides of the plate or bowl transverse to the direction of movement of the carriage are simultaneously flamed by burners 60 pivotally supported on vertical axes on the carriage and moving therewith (one burner at each end of the carriage, the rear of one such burner being shown). An arrangement of another cam track and follower and a mechanical connection between the burner supports causes the burners 60 to swing, during reciprocation of the carriage, so as to sweep the transverse ends of the plate a bowl at a constant distance therefrom.
