Patent GB-688212-A (GB)
Title: Improvements in or relating to the production of castings or other articles or components liable to develop faults in manufacture
IPC: G01N21/91
Filed: 1949-08-18
Abstract: 688,212. Testing physical qualities of materials. DE HAVILLAND AIRCRAFT CO., Ltd., and CLARKE, K. W. Aug. 15, 1950 [Aug. 18, 1949], No. 21531/49. Class 106 (ii). A process for detecting surface flaws in an article, comprises treating the surface with a water-emulsifiable oil, rinsing the oil from the surface of the article with water, drying said article and dusting thereon a finely-divided light coloured powder having dispersed therein an oil-soluble dyestuff. Oil seeping from any flaws in the surface of the article stains the dyestuff in the powder to indicate the presence of such flaws. The term " water-emulsinable oil " as used in the Specification means an oil capable of penetrating minute fissures and being either inherently or as a result of an added emulsifying agent, capable of being washed away from a surface by emulsification with water but sufficiently water repellant to resist penetration of the wash water into any fissures into which the water-emulsifiable oil has penetrated. The water-emulsifiable oil may be a water-in-oil emulsion in which the continuous phase is a water-insoluble oil containing an emulsifying agent. A water-in-oil emulsion is a water-emulsifiable oil because it can be easily washed away with water as a result of an inversion of the emulsion forming with the wash water an oil-in-water emulsion. The waterinsoluble oil may be a light mineral oil such as kerosine, pine oil, arachis oil, animal oil or oils from synthetic products such as nitrobenzene. A suitable emulsifying agent for the mineral oils is a soap or a mixture of soaps such as potassium oleate and triethanolamine oleate which may be incorporated with the oil by first mixing a higher fatty acid and triethanolamine with the oil and then adding an aqueous solution of the alkali, e.g. potassium hydroxide. The higher fatty acid may be oleic acid. Other higher fatty acid salts (i.e. having 8 or more carbon atoms) with water-soluble organic or inorganic bases may be used. A solubilizing agent such as methyl cyclo-hexanol may also be incorporated to clarify and stabilize the composition. Other agents serving this purpose are hydroxylated organic materials such as butyl and amyl alcohols, glycol mono-ethers, diacetin, diacetone alcohol and cyclohexanol. The rinsing operation may be carried out by spraying the water on the surface and the drying may be effected by the use of an air jet. Oil seeping from any flaw will cause an intense colouration of the oilsoluble dyestuff in the powder located over any crack or other faulty part of the surface. A suitable dyestuff is one sold under the colour index number 258 and known under the designation Oil Red " S," which gives a brilliant red stain at the defective areas.

Title: Improvements in machines for pressing grooves or vents in sheet material
IPC: B21D28/10
Filed: 1952-08-29
Abstract: 716,082. Stamping sheet material. AKTIEBOLAGET SVETSMEKANO. Aug. 29, 1952 [Aug. 31, 1951], No. 21758/52. Class 100 (2). [Also in Groups V and XXII] In a machine for pressing vents or gill openings 1, Fig. 1, with rounded end portions 2, 3 in sheet metal or pastics a die in which the vents are formed by a reciprocating punch has surfaces corresponding to the intermediate and end portions of the vents and is adjustable relative to the punch to bring the required surface into operative position. In one example, a vertically reciprocating punch 4, Fig. 2, has a curved forming surface 10 of part spherical form of the internal shape of the end portions 2, 3 of the gill openings 1. The die 5, Fig. 4, has an intermediate forming surface 25 of generally arcuate form with end portions 26, 27 of the outside shape of the ends 2, 3 of the gill openings. The die is pivoted by a vertical pin 17 on a mounting plate 15 and is turned and locked in the required position by a handle 18 engaging locking slots 21, 22, 23 in the plate 15. A flat face 11 on the die 5 forms a cutting edge 12 which co-operates with a fixed knife 14. In operation, the plate 15 is first lowered in the machine frame 8 or the stroke of the punch 4 is shortened so that the cutting edge 12 just engages the knife 14 as the punch 4 reciprocates to cut the slit for the vent 1 along its length. The plate 15 is then raised so that the die and punch fully engage to form the gill opening. In carrying out the succeeding operation on the next adjacent vent the plate is located in position by the engagement of the formed vent with a curved surface 28 on the knife 14. In a modification (not shown) a similarly shaped die is arranged to pivot about a horizontal pin, and in another modification the die 36, Fig. 8, is in the form of a shaped disc attached to a handle 38 pivoted on a pin 39 in line with the axis of the punch 1, so that the die may be moved to the side of the punch to form the ends of the vents. In a further modification a punch 42, Fig. 9, engages a die 44 having a recess 45 the shape of the intermediate portion of the vent 1 and over which a removable die portion 46, Fig. 10, with a handle 51 is fitted when the ends of the vents are being formed. The portion 46 has left and right-handed forming recesses 49 for each end, and other recesses 50 corresponding to the intermediate shape so that it may be turned over to form each end of the vent. A pin or snap lock is inserted through apertures 52, 53 to lock the parts together.

Title: Metering of consumer's electricity using a dispersed ring counter
Inventor: GREENAWAY JOHN FRANK
IPC: G01R21/00
Filed: 1966-05-17
Abstract: 1,133,375. Electricity meter signalling systems. ELECTRICITY COUNCIL. 16 May, 1967 [17 May, 1966], No. 21830/66. Heading G4H. In a signalling system for providing indications of the readings of integrating meters at a remote location, each meter has a control unit, a number of control units being connected in a ring circuit so that each prepares the next for operation and the meters are thereby sampled successively. Each meter has a bi-stable circuit having a pair of contacts which close at a rate depending on the rate of consumption of electricity, the contacts being sampled at least once between each change of state when the meter is operating at maximum rate. The control units are selected in succession by signals on lines A and B which are square wave signals of alternating polarity, each half wave being 40 ms. duration. The wave on line B lags by 10 ms. behind that on line A. The Kth unit comprises a relay Rk which is connected to line A by the closure of contacts Rj2 of the previous unit, successive units being interconnected by lines C. Relay Rk is picked by the positive half wave on line A via diode Hk1 and closes contact Rk 1 so that it holds by the positive half wave on line B via diode Hk2. There are two meters connected to unit k having contacts Mk1 and Mk2. When relay contact Rk3 closes, the meter contacts, through oppositely poled diodes Gk1 and Gk2, connect a signal line D to earth line F. The central station transmits a succession of 10 ms. positive and negative pulses in line D. If one of the meter contacts is closed, the corresponding positive or negative pulses is shorted to earth. If both are closed, both the positive and the negative pulses are shorted. The condition of the meter contacts can thereby be determined at the central station. The following negative pulses on lines A and B cause the relay Rl of the next control unit to respond, being enabled by closure of the "handon" contact Rk2. Between reading cycles control signals may be sent over lines A, B, D, and E to control the apparatus at the field stations. Positive or negative signals on line E cause relays Sk or Tk to pick. The contacts of these relays condition circuits to further relays which are selected by positive or negative pulses on leads A, B, and D. In another form adapted to respond to sinusoidal, rather than square waves on lines A and B each unit has two relays, one with diodes passing positive halfcycles and one with diodes passing negative half-cycles.

Filed: 1975-05-21
Abstract: 1461059 Milking apparatus P W KIRWAN 21 May 1975 [27 May 1974 8 Nov 1974] 21999/75 Heading AIM In milking apparatus, a milk line 3 conveying milk under vacuum from a teat-cup cluster 1 to a receiving vessel 4 has its major length enclosed in a water jacket to cool the milk and to heat the water. The cooling may be achieved by a single water jacket having apertures along its length through which dropper lines from the teat cup clusters protrude or by a plurality of separate spaced apart water jackets 20a, 20b, 20c, 20d leaving short sections of the milk line uncovered to facilitate connection of dropper lines 2 to the milk line 3. Preferably, the dropper lines and a milk line 10 leading from the receiving vessel 4 to a bulk storage tank are also provided with water jackets. The milk line and associated water jackets may be concentric or arranged such that the water carrying space has a substantially crescent shaped cross-section around the lower part of the milk line. To ensure maximum heat-exchange, the cross-sectional area of the water carrying space should be substantially less than the area of the milk line such as when the ratios of the diameters of the water jacket to the milk line are 6:5. The flow of water through the milk line jacket or jackets and/or the dropper line jackets may be independent or in series. If independent then the outlet or outlets may be fed into a common pipe or be used independently for washing, cleaning, making up foodstuffs or run to waste. Gate valves may be placed in the inlet line to the dropper line jackets to allow individual water jackets to be isolated to increase the water temperature.

Title: Production of chlorinated hydrocarbons
IPC: C07C17/14
Filed: 1944-11-10
Abstract: Xylylene chloride is obtained by exposing a mixture of xylene and chlorine to actinic radiation in the presence of an inert diluent and a trace of phosphorous pentoxide, the reaction medium being free from iron or aluminium compounds.  The xylene used may be one of the pure isomeric xylenes or a mixture of them.  During the later stages of the chlorination, the chlorine, advantageously, contains a small proportion of oxygen which reduces the tendency towards over-chlorination of the reaction product.  The phosphorous pentoxide which is added forms innocuous compounds with any iron or aluminium impurities.  The inert diluent such as chloroform or carbon tetrachloride may comprise 60-80 per cent of the mixture.  In examples: (1) chlorine is passed into reaction vessel containing p-xylene and carbon tetrachloride and 0.05 per cent phosphorous pentoxide, which is heated to reflux temperature and illuminated by artificial light or sunlight.  In the later stages of the chlorination 3 per cent of air is introduced into the chlorine feed line.  The p-xylylene chloride is obtained from the reaction products by frictional distillation in the presence of phosphorous pentoxide and purified by crystallization; (2) commercial xylene mixture is chlorinated as in example (1); (3) p-xylyl chloride which is obtained in (1) in addition to p-xylylene chloride is recycled in order to secure further amounts of the desired xylene chloride.
