Title: Improvements in and relating to machines for filling tubes for medicated and other semi-liquid substances
IPC: B65B3/16
Filed: 1923-11-15
Abstract: 227,245. Day, W. H. Nov. 15, 1923. Filling tubes.-Relates to machines of the type described in Specification 196,764 for filling medicated and other semi-liquid substances into tubes and closing them, and consists in an adaptation of the filling mechanism to allow it to be hand operated for dealing with small quantities. The pump and rotary shutter valve are operated by pedal mechan. ism embodying lost motion so that the pump and valve are separately operated except at the end of the delivery stroke. The tubes are placed by hand on a feed pipe 3 and retained by a spring finger 4. A rotary shutter valve is arranged below the hopper 1 and is adapted to cut off the connection to the hopper or to the feed pipe at appropriate times. The pump 2 is driven by a bell-crank lever 6 and a sliding rod 7 raised and lowered by pedals 8, 9. The lever 6 carries a pin 13 working in an angle slot 14 in the head of the rod 7. During the first portion of the elevation of the rod 7, the pin 13 is in the horizontal part of the angle slot and the lever 6 is moved to cause the suction stroke of the pump 2. When the pin enters the vertical part of the slot, the pump is no longer operated and the head of the rod 7 contacts with a stop 19 in a rod 17, operating a segment 15 and gear 5 in the valve to close the hopper and put the filling pipe into communication with the pump. In order to prevent the pin 13 from binding in the angle of the slot 14, a plate 23 with a slot 24 also engaging the pin is released by the action of the stop 19 on a trigger 27, thereby ensuring the travel of the pin into registration with the vertical part of the slot before its release. On the downward stroke of the rod 7 the pump and valve remain stationary until the pin 13 enters the horizontal part of the slot, when the 'pump is actuated to deliver the material into the tube on the feed pipe. The head of the rod engages an adjustable lower stop 21 and rotates the valve to cut off delivery from the pump. The tube has meanwhile been forced off the filling pipe and is placed by hand in a closing apparatus.

Title: Improvements in sewage treatment
IPC: C02F3/28
Filed: 1954-10-14
Abstract: 766,933. Treating sewage. DORR-OLIVER, Inc. [formerly DORR CO.]. Oct. 14, 1954 [Oct. 27, 1953], No. 29612/54. Class 111. Highly-concentrated sludge which may be produced by the method and apparatus of Specification 745,295 is fed continuously or at short intervals (e.g. from ¢ hour to 2 hours) at 70, Fig. 4, to a digestion tank 49 fitted with stirrers 65, sludge draw-off 55, re-circulating pump 57 and heater (not shown). Fig. 1 (not shown )is substantially the same as Fig. 6 of the above Specification, the main modifications being the omission of the pipe 49 for return of digester supernatant to the inflow pipe to the plant, and the addition of a sludge transfer pump in combination with a time-clock device in the digester inflow pipe.  Fig. 2 (not shown) is identical with Fig. 2 of the above Specification. The concentration of sludge fed to the digester is preferably high enough to eliminate the need for dewatering of the digested sludge. The digestion process is such that no supernatant is produced. Fig. 3 exhibits the relationship C2 between gas generated in the digestion tank as a percentage of the total gas available (ordinates) and digestion tank volume per capita in cubic feet (abscissae). The range of the latter within which the invention is practised is indicated at R2. The corresponding relationship C1 and range R1 for conventional sludge digestion processes are also shown. The variables in the expression for " Digester Index " shown on Fig. 3 are defined as follows : "g" is the amount, in cubic feet per day, of the available gas in the digested sludge discharged ; " V " is the volume, in cubic feet, of the digester ; " G " is the amount, in cubic feet per day, of the gas produced by the digester ; " Q " is the amount, in cubic feet per day, of raw sludge introduced into the digester. Assuming a fixed value for the Digester Index of 40 per cent for conventional digestion and of 120 per cent for high rate digestion, "g" is calculated, for a range of abscissa values, as a fractional multiple of G. In evaluating the equivalent ordinates, 100 (1-g/(g+G)), the variable G cancels. To attain a maximum Digester Index the digester must be operated so as to produce a maximum of gas and lose a minimum (g) in the sludge discharged while receiving the maximum sludge input into the minimum digester volume.

Filed: 1971-06-25
Abstract: 1384249 Making diaphragm springs GKN TRANSMISSIONS Ltd 23 June 1972 [25 June 1971] 29801/71 Heading B3A A method of setting into coplanar relation the inner ends 26 of radially inwardly projecting fingers of a diaphragm spring, which are integrally connected at their outer ends with an outer annular portion of the spring, comprises elastically straining an outer zone of the spring and whilst so strained, bending the fingers beyond their elastic limits to bring the ends 26 into coplanar relation. The spring, which forms part of a clutch, e.g. for a motor road vehicle, is placed with a pressure plate 14 and cover 10 in the apparatus of Fig. 6, with the cover resting on a seating element 49 and located angularly by dowels 50. A deforming element 55 is secured to the end of a rod 60, which is lowered, thereby bending the fingers, Fig. 1B, about fulcrum points comprised of projections 17 and wire rings 20, 21, Fig. 3. The cover, and hence the plate 14 and the spring are then secured by clamping units (45), Fig. 5 (not shown). The rod 60 is oscillated and a shoulder 58 on the element 55 bends the fingers cyclically within their elastic limit, Fig. 1(C). Plungers 70, which have been lightly engaging the fingers under the influence of springs 74, are locked at levels determined by the positions of their associated fingers by raising a sleeve 79 and wedge 85 and lowering a sleeve 97 clear of rollers 87, so that a spring loaded plunger 89 bears on the rollers. The plungers 70 are finally locked by raising the sleeve 79 a further predetermined amount. The element 55 is lowered bending the fingers inwardly of the plungers 70 beyond their elastic limit to bring the ends 26 into coplanar relation, Fig. 1(E). The element 55 is then raised and the clamping jaws (46) opened, the amount of spring back being substantially equal for each finger as it is released.

Abstract: 720,449. Fluid pressure vehicle brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., SIMMONS, A. W., and KERSHAW, J. W. G. Sept. 14, 1953 [Nov. 26, 1952], No. 29938/52. Class 103 (1). In an electro-hydraulic fluid pressure brake system for railway vehicles of the kind comprising lines 5 and 6 extending throughout the length of the train, of which three control coaches are diagrammatically represented at A, B and C, the line 5 controlling a service of holding valves 22 and the line 6 controlling a series of combined inlet and exhaust valves 14, 13, a further line 7 is provided which gives an indication to the driver that the electrical system is operating correctly. As shown, the train is being controlled from position A so that an isolating cock switch 2 is turned to connect the end of line 7 to earth through a buzzer 3. If the system is operating correctly, the brake cylinder pressure will operate to close a switch 8 on each vehicle so that current will pass through a circuit including a line 6, a pressure-operated switch 27, of which there is one at each control position opened only if there is air pressure in the hose coupling as at an intermediate part of the train, isolating cock switch 2 and switches 8. If the holding valve 22 should be open for any reason, the switches 8 will not be closed and the buzzer 3 will be inoperative. The line 7 might be energized through line 5 instead of line 6, but in this case since energization would be nearly continuous, it would be desirable to use a warning lamp in place of the buzzer 3.

The wheel may be driven by an internal-combustion engine or an electric motor. In the construction shown the driving and steering wheel 1 is mounted on a steering frame 2 which swivels about a steering shaft 8 supported in the steering head 3 fixed to the main frame (not shown). The main frame is supported on the steering frame 2 by rubber or other shockabsorbing means, the shaft 8 being slidable in bearings 6, 7 on the frame 2. The wheel 1 is steered by means of a hand wheel 10, chain or cable gear 13 and a wheel 15 or lever fixed to the steering frame. An internal-combustion engine 16 is secured to the steering frame and drives the road wheel through epicyclic or other change-speed gear and one or two trains of epicyclic or other reducing gear. The clutch housing 19 of the engine has a stationary fixed tubular extension 20 secured thereto, this extension passing centrally through the wheel hub 29 which is mounted thereon on bearings 30, 31. A gear casing 17, 28 is fixed to a flange 24 of the extension 20 by bolts 25. The clutch shaft 37 passes through the extension 20 and drives a concentric tubular shaft 40 through three-speed and reversing gearing comprising constant-mesh gearing 39, 44, lay shaft 43, a sliding pair of constant-mesh double helical gears 45, 46, and the usual gears 48-50. The tubular shaft 40 drives a sleeve 56 through a non-epicyclic reducing train comprising a pinion 53, pinions 53<a> revolving on the fixed bolts 25, and an internally-toothed ring 54. The sleeve 56 drives the road wheel hub through an epicyclic reducing train comprising a pinion 57, planet pinions 58, and a fixed toothed ring 61. The planet pinions are mounted on pins 59 of a carrier 62 which drives comprising rubber or other bushes 63 mounted in the hub and engaged by pins 64 on the planet carrier. The wheel rim 33 is detachablymounted on the hub 32 and is of such a size that it can be passed over the gear-box 17, 28, the gear lever 18 being readily detachable. According to the Provisional Specification, the steering frame 2 may be forked, one arm of the fork being hinged or readily-detachable to permit the wheel to be changed.
