IPC: E01C19/45
Filed: 1927-01-01
Abstract: 287,257. Warsop, H. E. Jan. 1, 1927. Cauldrons.-Plant for the production of bitumen and like emulsion for use for example on roads comprises a boiler a, Fig. 1, and a bitumen storage tank d heated to maintain the contents in fluid condition by the boiler gases, which pass through flues beneath and around the tank and thence to a chimney n. One or more furnace flues l are provided in the tank d for use in the event of the steam supply failing. The boiler a supplies steam to a steam engine e, Fig. 6, driving an air compressor c which supplies air to a reservoir r. The engine e also drives revolving blades in an emulsifying tank m and in a cooling tank f. The bitumen or the like is delivered to the tank d, Fig. 1, in a fluid condition either direct from a transport tank or from a preliminary heating tank s having its own furnace t. In the former case, the transport tank is connected with the compressed air reservoir r to force its contents into the tank d. This tank may if desired be connected to the suction side of the compressor c. Additional heat is supplied to the tank d by exhaust steam from the engine c passing through pipes o, Fig. 1, and thence by pipes p to a water reservoir j. Steam may also be supplied for heating to a pipe q if desired. To effect emulsification, the bitumen is forced out of the tank d by compressed air applied through a pipe g and passes through a pipe h into the mixer m accompanied by heated water from the tank j. From the mixer m it is withdrawn as an emulsion into the cooler f which is cooled by water passing through an external jacket and through the hollow shaft k of the mixing blades. This cooling water is then delivered to the feed pipe of the boiler a. The cooled emulsion is delivered direct into drums or transport wagons.

Title: Improvements in motor driven syrens
IPC: G10K7/04
Filed: 1923-01-04
Abstract: 208,918. Efandem Co., Ltd., Champion, A. T., and Eaton, J. Jan. 4, 1923. Sirens.-The rotor d of a motor-driven siren is automatically moved axially into and out of signalling relation with the stator c at the beginning and end respectively of a blast, by means of its own inertia, being mounted for this purpose with its central boss as an easily-running nut upon a quick-pitched screw-thread b on the driving shaft. In order that such movement of the rotor into signalling position may not take place until its speed is approaching the maximum, a spring-controlled catch g having a weighted end which engages a notched collar e prevents relative movements between the rotor and the shaft until the desired speed is reached, when the catch is freed by centrifugal force acting on its weighted end. Risk of jamming is minimised at one end of the axial movement by means of adjustable pins m abutting against the collar e, and at the other end by a pin i which is engaged by an axial pin k on the shaft before the end of the screw-thread is reached, such engagement causing the rotor thereafter to move with the shaft. The return of the rotor into non-signalling position is assisted by a spring n secured at ona end to the shaft, and at the other end to a pin q between two discs o, which are mounted loosely upon the shaft and held with the spring normally tensioned by means of a pin r engaging notches s. The Provisional Specification refers to a modification in which radial shoulders at each end of the threaded portion of the spindle are encountered by radial shoulders at each end' of the boss of the rotor. whilst to ease the frictional contact between the threads, the radial abutments are obliquely faced so as to tend to thrust the working faces of the threads apart, and a cushioning spring may be arranged between the abutments.

Title: Improvements in and relating to windscreen or like wipers or cleaning devices
IPC: B60S1/22
Filed: 1924-01-04
Abstract: 233,010. Portham, R. S. Jan. 4, 1924. No Patent granted (Sealing fee not paid). Windows and the like, cleaning. - Means for driving the oscillating shaft of a windscreen wiper from a continuously rotating shaft comprise a rotating member having an endless cam groove lying in a plane at an angle to the axis of rotation and adapted to oscillate an arm connected to the wiper shaft. As shown a worm 13 on the shaft 12 of an electric motor 10 drives a wormwheel 14, on the shaft 16 of which is fixed a spherical cam member 15 having an endless groove 18 in which engage two balls 19 carried in cups 20 formed on a forked member 21 mounted on the shaft of a pinion 22. This pinion meshes with a pinion 24 on the shaft 25 of the wiper so that as the cam member 15 rotates the wiper is oscillated. The forked member 21 may be made of spring steel or may have springs mounted on it to press the balls into the cam groove. To allow of manual operation the pinion 24 is slidably mounted on the shaft 25 and pressed by a spring 28 so that a notch in the pinion engages a pin 27 on the shaft; manual operation of the shaft 25 by a handle 26 causes the pin 27 to ride out of the notch. A casing enclosing the mechanism is divided into a part 6 for the motor and a part 7 for the transmission means, or the motor may be mounted separately and connected with the transmission means by a flexible shaft. The bearings of the shaft carrying the worm-wheel 14 and the cam member 15 are adjustable axially by means of tubular members 29, 30 screwed into sleeves mounted on the casing. In a modification the wiper shaft 25 is connected directly to the forked member 21 and manual operation is allowed by the balls leaving the groove in the cam member. The shaft 12 may be driven by a flexible shaft from the vehicle engine.

Title: Improvements in or relating to the treatment of filaments, yarns, foils and similar materials
IPC: D06C7/00
Filed: 1938-01-05
Abstract: 509,010. Treating filaments, yarns, foils, &c. DREYFUS, H., MONCRIEFF, R. W., and HILL, F. B: Jan. 5, 1938, No. 333. [Classes 2 (ii) and 15 (i)] [Also in Group VIII] In a process for the treatment of filaments; yarns; foils and similar materials with fluid media under pressure, wherein the material passes through a small orifice in the wall of the pressure chamber, a substantial proportion of the fluid medium which enters the orifice is diverted from the path of the material. The process is particularly applicable to the stretching of materials such as cellulose acetate or other organic derivative of cellulose during passage through a substantially closed pressure vessel containing wet steam or hot water at a temperature above 100‹ C. In the arrangement shown, four threads 1 from a creel of bobbins 2 pass through small orifices 3 into a compressedair chamber 4, between nip-rollers 5 and thence into a steam vessel 7 where they become stretched by rollers 9. In passing out from the chamber through orifice 8, the threads pass through holes 22, Figs. 2 and 3, while the pressure fluid escapes mainly through the radial passages 23. Instead of the device shown in Figs. 2 and 3, there may be used simply a plate positioned at a suitable distance from the outlet of the treatment vessel and pierced with a suitable outlet for the passage of the threads. The space between this plate and the treatment vessel may be partially closed so that the steam, after diversion by the plate, is forced to flow in one or more predetermined directions. Specifications 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, 443,773 and 488,794 are referred to.

Title: Velocity-dependent measuring and control systems
IPC: B61K7/12
Filed: 1954-01-06
Abstract: 751,224. Indicating speed photo-electrically. FRUNGEL, F. Jan. 6, 1954, No. 374/54. Class 40 (3). Apparatus for effecting a control at a particular velocity comprises an elongated source of modulated light at one side of a path of travel and a light actuated receiving device including a photo-cell on the other side of the travel and a relay receiving the photo-cell output pulses and activated only when the light is interrupted by a body passing through the beam at above a predetermined velocity. As shown, a relay is to be operated when a railway truck 11 passes in front of a modulated light. source at an excessive speed. The light source is a fluorescent lamp 10 a section 10a of which is viewed by a photo-electric cell situuated behind a lens and an angle limiting diaphragm 14. The pulsed output of the photocell 16 is amplified in a tube 19 and fed through an anode transformer, .the secondary of which is tuned, to a rectifier 21, which feeds a condenser 22 and resistor 23 in parallel. Provided the light reaching the cell is not interrupted a steady potential is built up across the condenser which is prevented by a blocking condenser 24 from reaching a winding of a relay 26. If a truck passes through the light beam however the potential across the condenser falls and the charge on blocking condenser 24 leaks away the resulting current through relay winding 26 operating the relay. The relay may be present to operate at a particular speed by means of a preadjusted backing off current in a differential winding. Variations in the light source intensity are compensated by means of a correcting voltage derived from the output of transformer 16, rectified at 32 and passed through a long time constant circuit to control the grid potential of tube 19. A number of photo-cells may be arranged to control a single relay if a truck passes any of them at above the predetermined speed. In the arrangement of (Fig. 4, not shown) all the blocking condensers 30 are connected through individual rectifiers to the grid of a triode with a relay winding in its anode circuit. This triode may include a number of relays in its anode circuit each of which operates at a different velocity. The light source may be situated in a parabolic reflector and is preferably of a colour widely different from that of daylight. A blue-violet fluorescent coating may be used and the photo-cell may be provided with an appropriate filter.
