IPC: B05B3/16
Filed: 1927-12-16
Abstract: 289,843. Lloyds & Co. (Letchworth), Ltd., (Assignees of Zeyslolff, P.). May 4, 1927, [Convention date]. Rotary apparatus.- Apparatus for automatically sprinkling areas of varying shape c, g, circular, squane, rectangular triangular &c. comprises a base on which is mounted a horizontal platform 1, the edge of which is provided with teeth 2 and the upper surface is, provided with a number of circular roller paths 3 presenting hills and valleys at different parts. A hollow member 5 integral with a, tube 6 which turns in a stuffing box 7 carries an inclined nozzle 13 in front of which is hinged a second nozzle 14 supported by a rod 15 of adjustable length the lower end of which carries a roller to engage the roller paths 3. Rotatably and slidably mounted on a pin 8 carried by the member 5 is a wheel 9 provided with vanes of varying length, and traversed by arms carrying governor balls 10, these arms being pivoted to arms 11 carrying an eccentric 12. The rod 15 moves in a guiding member 19 provided with a number of holes 19a through which a cotter may be passed to maintain the roller in engagement with one of the rol'er paths, the cotter holes being marked with a figure to indicate the shape and size of the area to be sprinkled. Around the central opening are a number of surfaces 4 having various outlines the position and shape of which correspond to the shape sprinkled when the roller engages the different paths 4 and serve to indicate the position in which the apparatus should be placed. A jet of water from the nozzle 13, the range of which is varied by varying the height of the second nozzle 14 engages the vane wheel 9 and causes it to rotate. Rotation of the wheel 9 rotates the eccentric 12 which engages a fork 21 and causes the lever 21 to reciprocate pawl mechanism by which the nozzle is slowly rotated around the central column, the range of the jet being varied as it rotates by the irregularities of the roller path. Normally the governor lifts the wheel 10 so that only the longest vanes are engaged by the jet, but on the speed falling the wheel is lowered and the shorter vanes are engaged. A stop 23 which may be placed in any desired position, engages a lever 22 to throw over the pawl mechanism and thus rotate the apparatus in the opposite direction. By this means any portion of an area of desired shape may be sprinkled.

Title: Improvements in or relating to control systems for elevators, hoists and the like
IPC: B66B1/50
Filed: 1928-11-21
Abstract: 301,030. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Bouton, E. M.). Nov. 23, 1927, [Convention date]. Light radiations, controlling apparatus by.- In an electric lift system the cage C is provided with light sensitive cells 16 .. 19, such as selenium cells or other cells having photo-electric properties of changing their resistance to the passage of electric current under varied conditions of light, which co-operate with light sources 20 .. 23, &c. to slow down the cage and stop it automatically at predetermined points. The cells 16, 17 and the corresponding light sources 20, 21, &c. function during the downward travel of the lift and the other cells &c. during the upward journey. The driving apparatus for the hoisting drum D' is of the variable voltage or Ward Leonard type. When the cage is to travel downwards the attendant moves the handle 24 of the cage switch to the right thereby completing a circuit for the down direction switch 2. The energizing of this switch completes a circuit supplying current to the generator shunt field winding GF thus causing the motor EM to start. The switch 2 also closes a self-holding circuit. As the switch is moved further a circuit is completed for the speed relay 3 which effects the shunting of the resistance 4 from the generator shunt field circuit and also completes a self-holding circuit. The cage switch can now be returned to " off " position without interrupting the running of the cage. As the cage approaches a floor, e.g. the second, the cell 16 will be brought opposite to the light source 21, and the relay 7 will be energized thereby breaking the holding circuit for the speed relay 3 and causing the reinsertion of the resistance 4 in the generator shunt field thus slowing down the motor. As the cage more nearly approaches the floor, the cell 17 is brought opposite to the source 21, and the relay 8 will be energized thereby opening the holding circuit for the down direction switch 2 and thus stopping the motor. The relays 5, 6 act in conjunction with the cells 18, 19 when the cage is moving upwards.

Title: Improvements in or relating to the manufacture of soap with recovery of glycerine from spent lye
IPC: C11D13/04
Filed: 1946-11-26
Abstract: <PICT:0658954/III/1> In a process for the rapid production of soap, the boiled soap is introduced in a fine stream into a graining bath maintained at the optimum graining strength and at a temperature between 60 DEG  and 95 DEG  C., the proportions and rate of introduction of the boiled soap being such that soap curds are rapidly formed and removed from the bath to a separating screen or the like where the curds are separated from contaminating lyes.  The graining column may consist of a number of baths so that they can be used in rotation to enable a continuous stream of boiled soap to be treated.  The curds after rinsing with water are pressed to expel any remaining lye, while the lyes screened from the curds are returned through a column of graining electrolyte to restore their strength and are then passed back to the graining bath, or they may be strengthened by evaporation.  The glycerine is allowed to accumulate in the lye until a strength of 50 per cent glycerine is attained, whereupon the lye is run off for glycerine recovery and a fresh graining bath introduced.  The graining bath may be a salt solution or a solution of caustic alkali which acts as a dehydrating bath. The strength of the bath is determined by small scale tests made from time to time as the process proceeds.  Referring to the diagrammatic drawing, the boiled soap produced either by batch process in a kettle D or by continuous methods in a reactor E, is pumped through narrow nozzles or injectors G into a series of high graining columns F.  The curds formed are carried to the surface and in admixture with some of the lye pass to rotary screens I or similar separators from which the curds are removed to spray washers J while the lye is returned either through a strengthening column L packed with graining reagent or through an evaporator to the graining baths F.  Specification 636,945 is referred to.

Convention date, Dec. 8, 1933. [Class 103 (i)] A fluid-pressure brake comprises an accelerating bulb having two chambers, the fluidpressure in one chamber acting on a diaphragm operating a valve which prevents the other chamber exhausting until the brakes are nearly or completely released, in order to avoid excessive venting of the train pipe and therefore excessive application of the brakes when they are alternately partially released and reapplied. When the triple slide valve 8 moves to application position it connects the train pipe 4 by a cavity 32 and passages 31, 41 to the chambers 22, 23 of the accelerating bulb. The chamber 23 is normally exhausted through a passage 35, which however is closed by a valve 25 operated by a diaphragm 24 influenced by the pressure in the chamber 22 so that the fluid is retained in the chamber 23 until the pressure in the chamber 22 has fallen to a predetermined value that is till the brakes are practically released. A quick inshot valve 19 supplies a " light " cylinder through a passage 12 and when a valve 19 closes, a " load " cylinder through a passage 13.
