Title: Improvements in and relating to means for automatically signalling when a vehicle passes over a predetermined point in a road
IPC: G08G1/02
Filed: 1919-12-09
Abstract: 159,977. Badger, E. Dec. 9, 1919. Addition to 138,792, [Class 118 (ii), Signals]. Falling-flap and other release indicators.-Comprises improvements on the invention described in the parent Specification, which relates to signalling means at cross roads for giving warning of approaching vehicles, the signal being actuated by road contacts depressed by the vehicle. Closure of the primary circuit a energizes the electromagnet 37, Fig. 12, at the signal post, thereby attracting the armature catch 37<1> which normally locks the rotary signal shaft 39 by engaging an arm 38 thereon. When the shaft 39 is thus released, instead of being driven by an electric motor as in the parent Specification, it is rotated through gear wheels by a spring motor contained in a casing, the shaft 39 projecting through the main casing and carrying at both ends signal arms and preferably black discs 40, Fig. 7, which rotate in front of frosted translucent screens behind which are arranged electric lamps. Coloured lamps comprising two pairs of projectors 59 arranged at right-angles are arranged at the top of the post 54 for use at cross roads, or one pair only is used at a junction. As the shaft 39 rotates, it transmits its rotation, through gears 45, 46, Fig. 12, to a countenshaft 47 carrying a wiper arm 50 with a spring plunger adapted to contact with a fixed segmental ring 52, whereby secondary circuits are completed as in the prior case, one circuit serving to hold the armature catch 37<1> out of action until the shaft 39 has made a prescribed number of revolutions determined by the gear ratio 45, 46 and the angle covered by the contact segment 52, while the second circuit c serves to illuminate the lamps 58 behind the rotary signal arms and the lamps 60 at the top of the post 54.

Title: Improvements in means for automatically indicating the head, height or the volume ofliquid in a container
IPC: B60K15/06
Filed: 1927-11-17
Abstract: 306,468. Rodman, J. B. Nov. 17, 1927. Indicators actuated by pressure of head of liquid. -The pipe system of a pneumatic liquid-lever indicator for the fuel tank of a motor vehicle is maintained full of air by an air pump operated by a weight which is reciprocated by the movements of the vehicle. The air pump E comprises a piston L which allows air to pass on the suction stroke but is air-tight on the delivery stroke. The piston is pressed upwards by a spring K and the piston rod supports a weight C sliding over a guide rod H. Air is delivered through a pipe G to a housing A open to the liquid, and connected by a pipe B to a pressure gauge which indicates the depth. Liquid enters the housing A through an opening A<1>. 'The weight C reciprocates owing to oscillations of the vehicle. The piston of leather, is free to move over a reduced portion 1 of the piston rod, Fig. 7, and is airtight when resting against the washer 5. The upper surface of the nut 3 is slotted so that when resting against the washer 4, air is admitted past the nut to the upper side of the piston. A guide member 6 is provided. Alternatively, a cylindrical piston may be used, with a conical central opening fitting over a conical part of the piston rod, but with freedom to lift slightly during the suction stroke (Fig. 8, not shown). Fig. 2 shows the application to a tank subjected to intermittent suction. The opening A<1>, Fig. 1, is omitted, and an additional tube N, open to the air at the top, is provided. This tube has a small opening 0 at the bottom, and an opening P into the housing A. In the event of a partial vacuum in the tank, air is drawn down through the tube N and opening 0 into the tank, so that excessive suction in the housing A and damage to the pressure gauge is avoided. In another modification, Fig. 3, not shown, a balance pipe is taken from the top of the tank to the other side of the pressure gauge, when the tank is at a pressure other than atmospheric. In a modified form of pump, Fig. 6, the piston L is operated by a weight C which is mounted on a pivoted rod U and is free to oscillate. The air may be discharged through a separate liquid seal containing glycerine, to a pipe dipping into the tank. The apparatus is applicable to ships or aircraft, and the piston pump may be replaced by a diaphragm or bellows pump.

Title: Improvements in or relating to rotary constant pressure variable displacement pumps
IPC: F04C14/10
Filed: 1948-11-30
Abstract: 651,689. Rotary pumps. HOUDAILLE-HERSHEY CORPORATION, and HUFFERD, G. H. Nov. 30, 1948, No. 31024. Convention date, June 4. [Class 110(ii)] A constant delivery pressure pump of the outwardly-sliding vane type has rotary, hydraulic, means to vary the displacement of the pumping chambers. A rotatable member 25, eccentric to the pumping chamber, is moved by admitting liquid under pressure to one side of an abutment 35, in a chamber 34 under control of a valve 53 and relieving the other side. The vanes 22 are held outwards by means of rings 23 contained in recesses 24 in the rotor 15. Liquid enters the pumping chamber 27 through a segmental port 30 and forced through a discharge port 31. When the delivery increases beyond the mean rated pressure, the valve 53 moves against a spring 57 until a bleed-off groove 63 registers with a port 70 which leads through a bushing 54 to a duct 71, in a boss 50, leading to a bleed-off groove 43. This places chambers in pockets 34, that are fed by shallow ducts 40 from the working-chamber, into communication with the suction side 65, 67, 30 causing the ring 25 to turn and decrease the capacity of the working chamber and the output pressure, until the valve 53 slides back under spring pressure. Excessive movement of the valve 53 causes a stop pin 58 to lift a valve 52 and move the ring 25 to minimum-displacement position and cut down the delivery pressure quickly. The abutment 35 is under pressure of a spring 38 and fluid pressure. In a modification, the valve 53 has further control points and moves responsive to a combination of high and low pressure selections, a port being - provided in the head of the valve.

In a method of attenuating noise, the acoustic energy transmitted through a duct is focused by an arrangement of acoustic reflectors so that it is concentrated on localized zones of the wall of the duct, appropriate acoustically absorptive linings being located at the said localized zones. The air intake of a compressor is shown in Fig. 1, comprising a casing 1, a centre body 3 and compressor 4. The centre body is formed with a parabolic surface 3a whereby acoustic energy from the compressor is reflected and focused at a circle F F<SP>1</SP> on the internal surface 2a of the casing 1. The internal surface is lined with acoustic absorptive material 5 in this region, the material 5 being for example a porous lining, resonators or cavities. In Fig. 2, a ducted fan engine is indicated comprising a fan 8, a highpressure compressor 9, a fan duct 7 and a compressor casing 10, the outer wall of the casing being formed as an acoustic reflector 10a of parabolic form by which acoustic energy from the fan is reflected on to a localized zone 11 of the inner surface of the duct 7, this zone being lined with acoustic absorptive material. In Fig. 3, the jet nozzle 12 of a jet engine discharges into a structure 15 which may be utilized when engine testing on the ground. The nozzle projects into a ring member 13 which is located within the casing 15 with an annular space 16 therebetween for inflow of ambient air. The outer surface of the member 13 is formed as a parabolic reflecting surface 13a by which acoustic energy is reflected and focused in the zone 14 of the inner surface of the casing 15 which zone is lined with acoustic absorptive material. A centre body 18 is disposed within the outlet of the casing to define an annular outlet 17. The surface of the centre body is parabolic at 18a and serves to reflect and focus acoustic energy in the zone 19 of the inner surface of the casing 15, this zone being lined with acoustic absorptive material.
