Title: Improvements in or relating to spark erosion
IPC: B23H9/06
Filed: 1969-06-12
Abstract: 1,206,578. Spark-erosion. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 June, 1969 [15 June, 1968], No. 29781/69. Heading B3V. [Also in Division G3] In a spark erosion process, a piezo-electrio element 6 secured to an electrode 10 performs a relaxation oscillation the oscillation period of which is determined by the current supplied to a capacitance formed by metal coatings 7, 8 on the element 6 and by the charge drained from the capacitance through the spark produced. A voltage is applied across the coatings 7, 8 by a variable current source 15 to cause the element 6 to move towards the workpiece which comprises a conductive layer 11 on an insulating body to be formed into an optical grating. When a spark is produced across the gap, the voltage across the coatings 7, 8 is discharged and the element 6 jumps back, the process being repeated to produce a relaxation oscillation. An additional capacitor 18 may be connected in circuit and a capacitor 17 and inductance 16 may be provided to control the spark energy. The element 6 is movable vertically by a rack and pinion 5 and horizontally by knobs 3, 4. When a workpiece having a contoured surface is machined, the gap width is kept constant by comparing the peak voltage at terminals 21, 22 with a reference voltage in a control device 20, the output of which is connected to a central electrode 19 and the coating 7 of the element 6. A plate 6b of the element 6 is caused to contract or expand according to the output deviation voltage V from the device 20, a plate 6a responding in an opposite manner, thereby causing the gap width to be kept constant. Alternatively the deviation signal may be used to control a motor which drives the pinion 5.

Abstract: 841,800. Forced-flow vapour generators. BABCOCK & WILCOX Ltd. Sept. 17. 1958 [Sept. 18, 1957], No. 29817/58 Classes 123(2) and 123(3) In a vapour generating unit for recovering heat from hot fluid under pressure, hot gases at superatmospheric pressure are delivered through an inlet duct 39 to two superheaters 30, 31 arranged in parallel and then through a cylindrical pressure vessel 3 which is divided by a cylindrical partition 14 into a central vapour generating section 1 and a surrounding annular economizer section 2, the gases being exhausted from the vessel through a duct 25. Steam generated in a cylindrical nest of upright tubes 6 in the section 1 and extending between the wet vapour space 7 of a spherical drum 4 closing the upper end of the vessel 3 and a spherical water distributer drum 8, passes over liquid separators 5 in the drum 4 and through a duct 26 to a distributer 27 having an outlet 27<SP>1</SP>. Steam for superheating passes from the distributer 27 and through ducts 28, 29 respectively to the superheaters 30, 31. Each of the latter comprises an inverted U-shaped casing 33 which encloses a nest of U-shaped tubes 34 connected at one end by a distributer 35 to the adjacent end of the respective duct 28 or 29 and at the other end to a collector 36 leading to the point of use. A water feed pipe 23, passing in a gas-tight manner through an aperture in the vessel 3, leads to an arcuate distributer 22 which supplies water to a two layer coil of spaced economizer tubes 18 helically wound around the partition 14. The latter surrounding the nest of steam generating tubes 6, extends substantially throughout the height of the partition. The upper ends of the tubes 18 communicate with a part spherical water trough 20 mounted centrally within the drum 4 to define the steam space 7. The lower end of the partition 14 is connected, by an extension 16, to a semi-spherical cap 17 an opening in the bottom of which communicates with a gas duct 12 connected to a gas duct leading from the superheater 30, 31. Gases entering the cap 17 pass upwardly over the steam generating tubes 6 in the section 1 and downwardly, through the annular section 3 accommodating the economizer tubes 18, to the exhaust duct 25. A large downcomer pipe 9 in the centre of the vessel 3 connects the trough 20 with the drum 8.

Title: A method for the automatic weighing of materials of various kinds into batches of equal weight
IPC: G01G15/02
Filed: 1934-10-18
Abstract: 445,876. Weighing-apparatus. POPOV, V. D., 743, Zelena ul, Bubenec, Prague. Oct. 18, 1934, No. 29873. Convention date, Oct. 19, 1933. [Class 143] In a method of weighing out batches of material into receptacles passed successively beneath a series of volumetric measuring devices of successively diminishing size, the addition or withholding of a measured volume is effected under the control of the various weighing devices and in dependence upon the supply by the first measuring device of its maximum or minimum quantity within a predetermined range of accuracy. As shown diagrammatically, a series of scale pans 2a, 2b, &c., or bags, boxes, &c., is moved intermittently by an endless or rotary conveyer so as to present the pans successively at the alternating measuring and weighing stations I, II, &c. At the station I the pan automatically receives a measured volume of material from a measuring device 3a, by a quarter revolution of a compartmented drum 4. The size of the measuring compartment is such that the volume delivered cannot exceed the final weight required, but owing to non- uniformity of the material may fall considerably short. The conveyer now moves on one step and the charge is weighed on a balance 7a. If the weight is below a predetermined limit an electric contact 11a is closed thereby allowing (after another movement of the conveyer) a second measuring device 3b to add a further volume of material, similar test weighings and further additions being afterwards made if required, at the successive, stations until the final weight is made up within a predetermined degree of accuracy. Owing to the inaccuracy of the measuring devices, the minimum weight delivered by any one of the delivery apparatus may be smaller than the maximum weight delivered by a subsequent apparatus.
