Title: An improved arrangement for tipping hutches or bogies
IPC: B65G67/00
Filed: 1920-07-24
Abstract: 167,380. MacBride, R. W. July 24, 1920. Vehicles, marshalling and manipulating. - An adjustable wheeled tipping-frame A, which is secured in proximity to the dumping-point by pins passing through registering holes 13 in the framework and the running rails, carries an inclined track which is looped to form a spiral intermediate its ends and is. curved through 180‹ at the upper end to lead to a parallel return track 4. The wagons are drawn along the track, for example by being clipped as shown at x to an endless haulage rope C, and the contents are discharged during the passage round the spiral. A guide rail 2<a> engages the upper sides of the wagon wheels during the discharging operation. The rope is guided in the spiral track by spring-pivoted forks 7 which are depressed in turn by the wagon in passing. The radius of the curve at the upper end of the track is made as small as is practicable, in order to reduce the over-all width of the frame, and a rotary table or drum 5 is inserted in the loop to assist the wagons in turning. The return track switches on to the main track again at the loading point. To allow for adjustment of the loading frame as the dumping proceeds, the haulage rope is tensioned by a pulley 14, Fig. 3, mounted on a wheeled carrier E connected to a tensioning weight G. A platform and railing 11 extends all round the edge of the upper surface of the loading-frame in order to facilitate access to the various working parts.

Title: Improvements relating to transistor switching circuits
Inventor: CARTER RONALD PHILIP
IPC: H03K5/08
Filed: 1961-06-20
Abstract: 1,019,625. Semi-conductor circuits. ENGLISH ELECTRIC CO. Ltd. June 15, 1962 [June 20, 1961], No. 29492/64. Divided out of 1,019,624. Heading H3T. In a switching circuit using a transistor of one conductivity type, the voltage drop across the base/emitter junction is offset by connecting an emitter follower of opposite conductivity type in series with the base. In the sine/square wave converter shown, the sine wave at terminal 1 is limited by silicon diodes 6, 7 and fed via an NPN germanium emitter follower 4 to a PNP germanium transistor 8. The biasing effect of transistor 4 ensures that the transition from conductive to non-conductive states of transistor 8 occurs at zero voltage so that a symmetrical square wave is available at the collector, the rise time of which is improved by a Schmitt trigger comprising transistors 10, 11 and an amplifying transistor 19. If silicon transistors 4, 8 are employed, diodes 6, 7 must be replaced by Zener diodes in series opposition.

Title: Improvements in apparatus for injecting liquid fuel into the combustion chambers of internal combustion engines
IPC: F02D1/00
Filed: 1924-09-22
Abstract: 229,213. Blackstone, G. M., Carter, F., and Carter, E. Sept. 22, 1924. Addition to 228,261. Buffers, springs, and the like; cam, lever, and spring actuated pumps ; stroke, varying ; valvegear.-The internal-combustion engine fuel injection apparatus described in the parent Specification is modified by providing a light spring e which retracts the pump plunger d on its suction stroke, thus rendering unnecessary a second pump to supply the fuel under pressure to the injection pump. The amount of fuel drawn into the pump chamber c is dependent upon the position of a governor-controlled wedge r, which limits the outward stroke of the injection plunger. The governor o is driven from the camshaft 1, carrying a cam m, which actuates the injection plunger d through a lever k, sliding cap g and spring j. A further modification consists in the use of a fluid operated injection valve, the passage of fuel which is controlled by the pump delivery valve which prevents injection of fuel until the valve v is opened by a projection on the arm k while the spring j is being, compressed.

Title: An improved centrifugal pump for mixed media
IPC: F04D29/22
Filed: 1959-06-30
Abstract: 928,416. Centrifugal pumps. ETA-CORPORATION G.m.b.H. June 30, 1959 [April 3, 1959], No. 22392/59. Class 110 (1). A centrifugal pump for mixed media, particularly a centrifugal pump of the kind employed for conveying liquid or gaseous media, or both, which entrain solids or slurries, comprises a casing having a central inlet and an open-sided bladed impeller mounted within the casing with its open side facing the inlet, the impeller having a plurality of stages with the delivery surface of the first stage extending substantially radially towards an annular outlet nozzle, the direct flow path to the outlet nozzle for material delivered from the surface being unobstructed by blades. In the two-stage pump shown, the front wall 2 of the casing and the edges 7 of the impeller blades are formed with respective radii of curvature 6, 8 about a common centre. The front wall 2 and the back wall 3 of the casing merge into the throat of an annular outlet nozzle 4 in such manner that the mean flow line 5 merges into the median axis of the nozzle. The widening angle a of the nozzle, which may be greater than 12 degrees, may be such as to cause breakaway of flow at at least one of the side walls of the nozzle, thereby forming cavities in which vacuum pressures arise, for the purpose of facilitating the pumping of liquids with gaseous occlusions. The delivery surface 11 of the first stage may project into the flow path as shown in dotted lines, in which case the front wall 2 may be similarly shaped with a projection at 12 to form a throat or nozzle-like constriction. The blades of at least one stage may be wholly or partly of rubber or the like; and the pitch, shape, obliquity and number of the blades may vary from stage to stage. The front and back walls of the easing may be generated by arcs of circles of the same radii so as to form a symmetrical annular outlet nozzle having an axial width at its entry which is greater than the inlet diameter of the casing and a throat width approximately equal to the inlet diameter so that large lumps of material entering the pump are not intercepted by obstructions. Specification 928,415 is referred to.

Title: Improvements in or relating to heat-plastic materials
IPC: C08C19/10
Filed: 1924-09-24
Abstract: 249,172. White, A. E., (Goodrich Co., B. F.). Sept. 24, 1924. Indiarubber, ismerizing.-Indiarubber is converted into more highly saturated isomers by admixture in the undissolved state with an isomerizing agent, followed by heating to initiate an exothermic reaction. According to the proportion of reagent used and the duration and temperature of heating the product may be either .(a) a resilient elastic product resembling soft vulcanized rubber, (b) a tough, thermoplastic balata-like substance, or (c) a hard, friable, fusible substance resembling shellac. The preferred isomerizing agents are substances of the formula R.SO2.X, R being an organic radical or a hydroxy group and X a hydroxy group or chlorine. Any other isomerizing agent, such as the chloride of an amphoteric metal, may however be used. The product is usually homogenized, e.g. by mastication, after the isomerization. As an example of the preparation of an elastic product, rubber is mixed with 4-5 per cent of its weight of p-toluene sulphonic acid and is heated to 120‹ C. for 20-40 hours. To obtain a balata-like product, 100 parts of rubber and 10 parts of p-toluene sulphonic acid are heated for 48 hours at 110‹ C., followed by 48 hours at 120‹ C. The shellac-like product may be obtained by thoroughly mixing 100 parts of rubber, 8 parts of p-toluene sulphonic acid, 2 parts of sulphuric acid, and 2 parts of water, beating for 8 hours to 140‹ C., whereupon an exothermal reaction commences and raises the temperature to 220‹ C., and allowing to cool. The Specification mentions many other sulphonic acids and sulphonyl chlorides which will serve as isomerizing agents.

Abstract: 517,645. Protective cut out arrangements. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 4, 1938, No. 23086. Convention date, Aug. 4, 1937. [Class 38 (v)] A protective arrangement for a network in which the circuit is opened and reclosed immediately afterwards once or a number of times on fault, has in series with a circuit-breaker for normally opening and closing the circuit, at least one group of two parallel-connected circuitbreakers which are arranged and coupled together so that one is closed immediately after the other is opened, the operating mechanisms of these breakers being dependent on protective relays. The latter may also control the "normal" breaker so that the latter finally opens the circuit on persistant faults. In Fig. 1, the "normal" breaker 1 is provided with a retaining coil 5 and is operated for normal switching by means of the press button 9. When the fault-responsive relay 11 operates, the circuit of the operating coil 6 of the parallel-connected breakers 2, 3 is made from the busbars 8 over the working contacts of a relay whereby the main circuit is broken at 3 and immediately after re-made over 2. If the fault persists, the relay 10, which is delayed in relation to 11, opens the circuit of coil 4 and makes a maintaining circuit for itself over contact 12, whereby 4 remains de-energized and the circuit broken until the maintaining circuit is broken, when next the breaker 1 is manually reclosed. All the breakers may be separate from one another or structurally combined, and instead of 2, 3 being mechanically coupled, as shown, with means for varying their time-difference, they may be provided with separate operating mechanisms and interlocked by relays to ensure the correct time-difference between their operation. The circuit-interrupting breaker may be provided with arc-extinguishing means. Instead of the normal breaker 1 being employed for finally opening the circuit, this may be performed by a further series-connected breaker, Fig. 2 (not shown). A further arrangement provides for more than one instantaneous reclosure by arranging two groups of breakers, as 2, 3, in series, Fig. 3 (not shown).
