Patent GB-190209677-A (GB)
Title: Improvements in or applicable to Intensifiers for Hydraulic Machinery
Inventor: DEAN JOHN JOSEPH
Filed: 1902-04-26
Granted: 1903-04-25
Abstract: 9677. Dean, J. J. April 26. Intensifiers.-Relates to an intensifier for baling &c. presses, rams, and other hydraulic machinery. Interposed in the supply pipe j is a casing d in which is arranged a plunger or valve e, the stem of which is coupled to a weighted lever b. The supply pipe j is coupled to a vertical pipe l, high and low pressure valves q, p being arranged below and above the junctions. Each of these valves is connected by a link m to an adjustable rod depending from the end of the lever b, the arrangement being such that, when one valve is open, the other is closed. The lower part of the pipe l is connected to the cylinder a of the intensifier, and the upper part is connected to a pipe v, which passes down into the hollow piston u of the intensifier. Non-return valves r, s are inserted in the pipe. The branches of the delivery pipe x lead from the cylinder and the pipe v and are coupled to a pipe y leading to the machine &c. A non-return valve w is arranged in the pipe x. When low-pressure water is required, the valve q is closed and water passes from the pipe direct to the pipe y, some of the water also passing down the pipe r and forcing the piston u to the bottom of the cylinder. When additional pressure is required, the position of the weight on the lever b is so adjusted that the water pressure is sufficient to lift the plunger e, thereby raising the lever b, so as to close the valve p and open the valve q. Water then passes into the cylinder a and raises the piston u, forcing the water in the hollow piston up the tube v to the pipe y under increased pressure. In a modification, the valves p, q are geared together by toothed wheels, one of these wheels being coupled to the lever b by links. The pipe v passes through the crosshead z, and the lower end of the pipe x is coupled to the lower end of the pipe instead of to the cylinder.
Patent GB-190214862-A (GB)
Title: Improvements connected with Electrical Controlling Means for Elevators or Lifts and other Apparatus.
Filed: 1902-07-03
Granted: 1902-10-09
Abstract: 14,862. Otis Elevator Co., [Otis Elevator Co.]. July 3. Motors, controlling.-Relates to electric controlling-means for elevators or lifts and other apparatus, and consists in the use of low potential for the circuit by which the high-potential motor-controlling circuit is controlled. Fig. 1 shows the application to a system in which a cage C actuated by an electric motor A serves four floors Y, Y', Y<2>, Y<3> , at each of which is a push-button P, there being corresponding push-buttons in the car. The low-potential push-button circuit may derive its energy from a battery E, while the motor-controlling circuit is supplied from the mains. F is the reversing-switch operated by either the up solenoid U or down solenoid D. The floor controller G may be of any kind, but preferably comprises the insulated segments 15, 16, with one of the insulation strips 17 broken by conducting-scrips e,f connected to two insulated segments a, b with which brushes g, h make contact. The arrangement is such that, on the car nearing the desired floor, a circuit is made through one of the bars e,f, the corresponding brush g or h, and the solenoid i or k, thus closing a circuit by which the motor is slowed down. On pressing one of the buttons P, that at the floor Y<3>, say, the cage being near the bottom floor, the battery circuit is made through the normally-closed switches H', I, wire 22, button at the floor Y<3>, wire 23, the winding s of one of the magnets W, and the winding r of a magnet R. The magnet R thus closes its contact and the particular energized magnet W its contact t, and the motor-controlling circuit is made through the winding r' of the magnet R, door switches T, safety switch S on the car, magnet H, contact t, and winding s<1> of the energized magnet W, corresponding brush 19 of the floor controller G, brush 21, stop-motion switch K, solenoid U, solenoid U<2> of the motor switch, switch K, and limit switch 35. The motor is thus started, and at the same time, owing to the energization of the magnet H, the switch H<1> is opened, and the lowpotential push-button circuit broken. The windings r<1>, s<1>, however, keep their contacts in the motor-controlling circuit closed. An additional means for ensuring the opening of the push-button circuit is supplied by the switch I, which is opened by the magnet 43, which cuts out the starting- resistance as the motor comes up to speed, In a modification, the switches T, S are in the battery circuit instead of in the motor-controlling circuit, but they are caused to remain in circuit when the push-buttons are cut out by completing the circuit through the core of the magnet H.

Title: Improvements in Electric Accumulators.
Inventor: DANZER HENRY
Filed: 1902-07-23
Granted: 1903-10-23
Abstract: 16,354. Danzer, H. July 23. Secondary batteries.-The lead plates 11, arranged in vertical or horizontal rows and alternately positive and negative, are provided with smooth or star or like shaped tapering projections 12 on both sides, except that the outer faces of the end-plates may be without projections. The projections on each plate fit between those of the adjoining plate or plates. The active material is retained between the plates and porous, insulating, acidproof coverings 16, 17, which may be of asbestos and are secured to the plates by hollow insulating-rivets 15, to allow free circulation of the electrolyte. The plates and coverings are granulated or roughened to increase the adhesion of the active material. The plates are secured together by insulating or insulated rods 19, and are kept at the required distances apart by insulating tubular distance-pieces 20. The plates are enclosed in an outer casing 24. All the positive plates are connected by lead strips 23 to one terminal, and all the negative plates to another. The Provisional Specification states that the projections on each side of the plates are joined by cast or moulded sheathings, which serve to increase the rigidity of the plate.

A collar b<1> having teeth b corresponding to teeth a<6> on the collar a<1> is rigidly connected to the crank shaft c. On it is an outer fixed collar b<2> with teeth b<3> corresponding to teeth a<7> on the collar a<5>. The handle a together with the collars a', n<5> is slid along the shaft until the teeth a<7>, b<3>, a<6>, b, engage. As the shaft rotates, the teeth a', b<3> slip, but are kept in contact by pins a<8>, actuated by springs pressing against the collar a'. Tn the event of back-firing, the collars a<5>, b<2> are fixed by the interlocking of the teeth a<7>, b' while the action of the teeth b, a<6> rotates the collar a' causing it to withdraw, due to the pin a<4> working in slots a'. Fig. 4 shows a modification in which the teeth b<3> are replaced by a pawl b<4>, and the collar a' is kept in position by a spring on the crank shaft c.

Title: Improvements in or relating to Variable Throw Devices
Filed: 1903-01-15
Granted: 1903-11-19
Abstract: 1078. Chapman, W., and Warfield Co. Jan. 15. Feed-pumps; pump stroke, varying.-Relates to a device for varying the strokes of feed-pumps used for either water or liquid fuel. Fig. 1 shows a side elevation of the arrangement with the pump in section. The pump plunger A<1> is connected to the link D, which can be moved as desired in the head of the plunger so as to vary the stroke. The link is connected to the eccentric B at its lower end, and is arranged to give its full stroke when in the position shown. The other end of the link is connected to the radius arm E, the link itself being an arc about the centre of the shaft C. The result of this arrangement is that, no matter what position the arms E, B<1> may be in, the plunger always completely empties the pump cylinder during its working stroke. In a modification, the arm E is dispensed with, and a stud, placed in the upper end of the link, is free to move in a suitable slot formed in a fixed plate.
Patent GB-190303173-A (GB)
Title: Manufacture of Artificial Perfume and of Intermediate Products therefor.
Inventor: IMRAY OLIVER
Filed: 1903-02-10
Granted: 1904-01-07
Abstract: 3173. Imray, O., [Meister, Lucius, & Br³ning]. Feb. 10. Trimethylcyclohexanonecarboxylic acid, probably of the formula is obtained by the action of sodium and dry carbonic acid on trimethylcyclohexanone in presence of ether, while cooling. The sodium salt is dissolved in ice-cold water, and the solution separated. It is converted into the acid by adding a dilute mineral acid. Trimethyl-oxy-cyclohexanecarboxylic acid, probably of the formula is obtained by reducing the trimethylcyclohexanonecarboxylic acid, by gradually adding sodium amalgam, passing a strong current of carbon dioxide, and acidifying. Or, the same trimethy] - oxy - cyclohexanecarboxylic acid, and another which is stereoisomeric therewith, are obtained from the same source by electrolytic reduction. Cyclogeraniolene aldehydes.-Two modifications, probably of the formulµ in alpha-modification #-modification are obtained by subjecting the calcium salt of the last-described acid and calcium formate to dry distillation in a vacuum. Cyclogeraniolidene-acetones, C9H5.CH# CH.CO.CH3. The alpha- and #-aldehydes are condensed with acetone, first at a low temperature in presence of very dilute or feeble alkaline agents which cause reaction of the alpha-modification, and then, after separation, causing acetone and condensing-agents to act on the #-modification at a high temperature. Condensation also occurs by heating the aldehyde with acetone alone in a closed vessel at a high temperature. When concentrated, these acetones have an intense odour of cedar wood, and, when strongly diluted, that of violets.

Title: Improvements in Condensing Locomotive and other Steam Engines.
Inventor: IVETT DANIEL RUBEN
Filed: 1903-03-18
Granted: 1903-10-22
Abstract: 6290. Ivett, D. R. March 18. Condensers; airpumps; exhaust, disposing of.- Relates to condensing locomotive and other steam engines, the exhaust steam being subjected to jets of cold water. The uncondensed steam remaining is compressed by pumps and forced into the boiler again. Fig. 3 shows a sectional view of a locomotive. The saddle-pieces U, D' of the locomotive are bored out to form the cylinders E, E', the valve-chests G, G<1>, the condensers 5, 6, and the pumps 7, 8, and are supported on theframingc. The exhaust steam is led by the passages M, M<1> to the condensers, where it is made to flow around spiral passages 21, as shown in Fig. 2, which shows a section through one of the condensers. These passages are formed by spiral flanges 20 on the surface of the short cylindrical shells 17, 18, which fit into opposite ends of the chambers 5, 6. The condensing-nozzles 22, 23 are disposed on opposite sides of the baffle 15, and are held in position by the shells 17, 18. Cold water is pumped into the pipes 33, by means of the pumps 51, 52, worked off the driving-axle B, as shown in Fig. 5, the water being led from the tender by the pipe 53. The branches 35 of the pipes 33, feed the chambers 30 which have rose plates 31 fitted so that the water is sprayed into the spiral passages. The mixed steam and water enters the interior of the shells 17, 18 from the spiral passages by means of orifices 32, and the inclined baffle-plates 29 direct the mixture to the heads 19, through which a stream of cold water is flowing from the pipes 33. The water and steam then pass the spray plates 27 through the holes 28, and issue through the nozzles 22, 23 on to the baffle 15. The condensed steam and water is led away from the space 16 by the pipe 36 to the pumps 55, and is returned to the tender by the pipe 56. The uncondensed steam passes through the passages 37, 38, which are provided with usual non-return valves, to the compressing pumps 7, 8, as shown in Fig. 7. The pumps consist of pistons on the rods 13 which are worked through levers from the driving-axle. The pipes 40, 41 lead the steam back to the boiler through a check valve. If the engine is desired to be non-condensing, the valve 47 in the blast nozzle is opened, the supply of cold water cut off from the condensers, and the air valves 68 to the compressing pumps opened.
