Title: Improvements in road signalling devices
IPC: G08G1/02
Filed: 1925-10-13
Abstract: 266,016. Ross, T. B. Oct. 13, 1925, Road signals.-A resilient tube containing fluid is interposed in the path of a vehicle near crossroads, turnings, &c. and is deformed so that the fluid actuates signal-operating means when the vehicle passes over the tube. A second tube may be located alongside the first to prevent a signal being given by a vehicle moving away from the cross-road &c. or to extinguish a signal previously given. As shown in Fig. 2, the inner chamber 12 of a tube 11 is connected to a cylinder 15, so that deformation of the tube actuates a piston 16 to close contacts 19, 20 in the circuits of an electromagnet 22. The core 23 of the magnet carries contacts 24, 25 that engage conducting strips 26, 27, the second of which may be broken to cause a flashing signal to be given by a lamp 5 in a cubical casing suspended diagonally above the road. The contacts 24, 26 close the circuit of a lamp 6 illuminating an arrow 3 visible from the intersecting road. A dashpot 31 causes the core 23 to return slowly to inoperative position. In the form of apparatus shown on the left of Fig. 6, operation of the tube 11 closes the circuit of a coil 35 by which the circuit of a battery 38 is completed so that the coil 35 remains energized and the signal lamps 5, 6 remain lit even when the tube 11 is released. A second tube 111 nearer the cross-road is then actuated to close a short-circuit of the battery 38 through a resistance 39, so that the coil 35 releases its plunger to open the signal circuit. A white line composed of studs 40 may be used in conjunction with this arrangement. As shown on the right of this Figure, a second tube 211 is placed on the remote side of the tube 11, so that when a vehicle is moving away from the crossroad, actuation of the tube 211 short-circuits a battery 42 by which the electromagnet 22 is energized. and the magnet 22 being made slow-acting, it is de-energized before it has time to close the circuit of the lamps 5, 6. A vehicle approaching the crossing closes the short circuit, but this is re-opened before the tube 11 is depressed, so that the signal is given as described with reference to Fig. 2. A tube may be placed in the road closed by level-crossing gates, contacts on the gates ensuring that no signal is given unless the gates are closed. Instead of one casing placed over the centre of the roads, separate lamps may be provided for each road, or reflectors having a cover only removed by the passage of a vehicle may be used, and an audible signal may be used in addition to the visible signals. The resilient tubes may have flanges 14 to keep out dirt &c., and they may be anchored by metal strips embedded in the rubber. Screens or lenses on the top of the signal casing enable colour signals for the guidance of aircraft to be given continuously, or intermittently by the passage of traffic along the roads, suitable combinations of colours indicating particular routes. Reference has been directed by the Comptroller to Specification 263,542.

Abstract: 1,209,117. Looms; weft control. NORTH AMERICAN ROCKWELL CORP. 28 May, 1968 [29 May, 1967], No. 25560/68. Heading D1E. In a loom in which pairs of connected picks are inserted into the sheds in an unvarying sequence the weft guide fingers are moved between operative and inoperative positions via cam discs. The fingers 67, 68 are rotatably mounted coaxially adjacent a cutting and clamping device 24 and a presenter 84. The fingers swing the weft into the path of the presenter by means of pivoted levers 32, 33 mounted on the reciprocating second pick positioner 27 and alternately engaging followers connected to the fingers. The levers are alternately pivoted by arms 36, 37, pivoted about axis 35 by cam discs rotatably mounted on axis 45. The cams are of like configuration, but are diametrically opposed. The sequence of operation is as follows: The first pick of one yarn is taken as a loop into the shed and then straightened when released by clamp 24. The other finger is then moved to operative position and a second and a first pick of the second yarn are inserted. This is followed, when the first finger is again operative, by the interconnected pick of the first yarn.

A conveyer mechanism wherein each leading block-shaped article 11 conveyed between guides 13 is removed in succession from an endless band feed conveyer 12, in a direction transverse to that of feeding, by a pusher 16 which delivers the successive articles on to a platform 18 for further transfer by an endless pusher conveyer 21 to a wrapping machine, comprises a feeler 45 freely pivoted above the conveyer 12 and actuable by the leading article 11 as it reaches a pre-determined position and the operating plunger of a micro-switch 50 being adapted to be moved by the feeler 45 upon such actuation into an operative position to render the pusher 16 operative. The pusher 16 is pivoted at 22 to an arm 23, 58 which is pivotally mounted at 24. An abutment 33 on an extension 34 of the arm 23 is held in engagement with an abutment 32 on an extension 35 of an arm 31 freely pivoted at 24, by a spring 36. A crank 27 driven continuously in timed relationship with the pusher conveyer 21 actuates via a link 29, the arm 31 which through the spring 36 actuates the arm 23 and pusher 16. The arm 23, 58 is however manually spragged by a spring-loaded spragg 55 to prevent the pusher 16 from operating. The spragg 55 is lowered from the path of the arm 58 by a solenoid 51 actuated by the micro-switch 50 when an article 11 has engaged the feeler 45 and pusher 16 therefore transfers the article. The pusher 16, on its return motion is elevated above the line of articles 11 by a lever 39, 41. The latter is pivoted at 42 and actuated by roller 43 and cam 44, coupled to the crank 27, to raise and lower the end 39 of the arm incorporating a track 37 in which runs a roller 38 mounted on the pusher 16.

Title: Improvements relating to the production of hot gases by the burning of liquid fuel
IPC: F23C99/00
Filed: 1956-08-23
Abstract: 825,880. Liquid fuel burners. FRASER, R. P. Aug. 16, 1957 [Aug. 23, 1956], No. 25840/56. Class 75(1) [Also in Group XII] A burner for the partial or complete combustion of liquid fuel with the product utilized elsewhere for combustion or chemical processes or the speed of the hot jet being used for fast convection heating, moulding and heating an' article, or heating and conveying an article, comprises an atomizer wherein atomization is effected by 25 to 100% of the air stream, the air being passed through the burner with a pressure drop of less than 2 lb./ sq. in. and the atomizer having means whereby the liquid fuel and air is maintained in constant proportion, whatever the flow quantity and the burner has means whereby a portion of the partially or fully burnt combustion products from the combustion space of the burner is recirculated to the entry point of the atomized fuel and air mixture. In the form shown liquid fuel controlled by a V- notched plunger 7 passes to the bore of a tube 1 at the end 2 of which the liquid fuel issues as a lateral spray to be atomized by air discharging around the oil tube, this atomizing air being that portion of the air entering the burner at 9 which enters by ports 10 into an intermediate tube 3 having a converging-diverging discharge-end orifice; the remainder of the air entering at 9 is discharged through a nozzle 5 to converge on the issuing atomized fuel. The air and atomized fuel enter a ceramic tube 18 spaced from the wall 20, 21 of the combustion chamber to provide a recirculation passage 19, formed by the annular space outside the ceramic tube 18 or by flutings on its exterior; the ceramic tube also acts as a flame holder by the sudden enlargement of the combustion passage occurring at its forward end. Thus a part of the combustion product is recirculated to the point of entry of the air and atomized fuel to heat up the same. The ceramic tube is adjustable axially along the combustion chamber. Dilution air entering under the control of a damper 22 into an annular space around the ceramic wall 20, 21 of the combustion chamber may be whirlingly discharged through vanes 23 at the forward end of the combustion chamber to mix with the discharging products of the burner. The proportionate adjustment of the fuel and air is effected by simultaneous linked axial adjustment of the V-notched plunger 7 and of the intermediate tube 3 which co-operates with the nozzle 5 and the shaped exterior of the liquid-fuel tube 1 to regulate the atomizing air and the converging combustion air supply from the nozzle 5; the dilution-air damper 22 is also linked for simultaneous operation. Specification 679,142 is referred to.

Abstract: 1,270,806. Aerials; pulse radar. EMI Ltd. 12 May, 1969 [31 May, 1968.] No. 26084/68. HeadingsH4A and H4D. Two interleaved aerial arrays produce respectively the sum 1, Fig. 1, and the difference 2, 3 patterns; there is no coupling between the arrays. In the embodiment one array consists of slotted waveguides 4, 5, 6, 7, Fig. 2, and the other of slotted waveguides 8, 9, 10, 11; the waveguides may be ridge waveguides. As applied to a radar the pulse transmitter is coupled to guides 4 ... 7. It is stated that there is no coupling between the arrays because the patterns are sum and difference types and are produced substantially by the same aperture. Lobe 2 output is in phase quadrature to the sum signal and lobe 3 output is of opposite phase to lobe 2, Unwanted grating lobes are reduced if the array interleaving is close. The output of detector 20 has a polarity representing the target direction off the sum signal axis and an amplitude representing the magnitude thereof. The output of detector 19 (which responds to the sum pattern only) may be used for ranging and automatic gain control. The output of detector 20 may be utilized to tilt the aerial system to follow the target in elevation, and to follow it in azimuth the lobes are shifted by altering phase in the waveguides; that output may also be utilized for producing a moving-target display from sideways-looking radar on an aircraft.
