Abstract: 692,754. Cowmilkers. ECREMEUSES MELOTTE SOC. ANON. June 27, 1951, No. 15310/51. Class 84 A milking apparatus is charaterized in that a vessel 45, arranged close to the teats, is connected to the teat cups 48 and, by the milk conduit 40, to the closure of a final container 23 for the milk which is situated at a lower level than the teat cups, and in that there are also provided conduits 42, 49 between a vacuum conduit 37 and the teat cups, and a conduit 36 between the vacuum conduit 37 and the final container 23, so that the vessel and the teat cups are continuously subjected to vacuum during milking. The vessel 45 into which the teat cups deliver the milk is funnel-shaped and made of transparent material, and 'is of such capacity as to contain all the milk taken from the teats by each "pulse," the milk then passing via the line 40 to the container 23. The vessel and teat cup assembly is supported by an arrangement 51 comprising a rod 51b which is axially movable within a tube 51a, by a handle 51c, and which carries an arm 53. A helical spring 52 urges the arm 53 and a further arm 55 pivoted thereto in a forward direction. The vessel 45 is attached by means of a "bayonet-type" connection to the arm 55, which connection. also permits limited universal movement of the vessel on the arm. The handle 51cis rotated until the arms 53, 55 (which are of springy material) exert a downward pull on the teat cups. The container 23' is supported from an overhead conveyer 24, 25 by a block-and-tackle, 26 ... 29, and a weighing device 30. The device has a simple resetting pointer for indicating the yield per cow and a friction driven totalizing pointer. When full, the container is moved by the conveyer 24, 25 on to a downwardly inclined roller conveyer (not shown) which removes it.

Title: Improvements in or relating to methods of forming flares at the ends of glass tubes
IPC: C03B23/09
Filed: 1953-06-03
Abstract: 731,765. Glassworking. GENERAL ELECTRIC CO., Ltd., DAVIDSON, T. R. N., and SCRUTON, A. H. June 3, 1954 [June 3, 1953], No. 15338/53. Class 56. Comprises a method of and means for making at the end of a glass tube a flare having an accurately shaped end surface by which the tube may be welded to another glass surface, particularly the flat end of the conical central portion of a cathode-ray tube. In the form shown in Figs. 2 and 4 the tube is rotated and heated externally, and the heated portion is acted on by an inclined roller 3, entering the bore, and external rollers 6. The tube is simultaneously moved axially (towards the left in Fig. 2) whereby a thickened portion is formed, the thickness decreasing inwards, and the outer end being bevelled as at 7. A forming tool 9, 8 is now inserted and the lever 8 is swung so as to form the flare against a shaper roller 10; what was the bevel 7 now becomes an accurate surface at right angles to the axis of the tube. In another form the tool is gradually withdrawn during the flaring process whereby a curved flare is formed. In the form shown in Fig. 7 a mandrel 17 having a part-spherical cap 22 pivoted thereto is advanced axially into the rotating tube from the rear with the cap 22 locked thereto. Further movement of the operating lever 32, 37 causes the tip of the cap 22 to project somewhat from the thickened end of the tube and unlocks the cap from the mandrel. The cap then pivots downwardly under gravity to flare the thickened end against the shaped roller 10, the bevelled end 7 moving to the position wherein it is at right angles to the axis of the tube.

Abstract: 862,755. Burning moil off glassware. CORNING GLASS WORKS. May 6, 1959 [May 13, 1958], No. 15584/59. Class 56. Apparatus for burning moil off hollow glassware includes means for supporting a workpiece and rotating it about a substantially vertical axis while applying flames at a horizontally localised region extending around the workpiece from a plurality of radially adjustable arcuate faced burners. In the form shown in plan, the hollow glass member 75 is mounted in a chuck 57 supported, through a number of concentric adaptor rings, from a ring 25 running on a track on a base plate 21. The chuck and the parts supporting it are incomplete rings. A chain 35 is secured to the ring 25'and provides a drive from sprockets, one of which is shown at 36, carried on stub shafts 40, 41 driven by chains 42, 43 through a clutch C and a belt 52 from a motor M. Three equally angularly spaced burner units 70 carried on a plate 13 below the plate 21 are radially movable on rods 46 between an outer position in which the glassware 75 is loaded into the chuck and an inner position for burning off the moil. The movement is effected by pneumatic air cylinders, the three burner units being interconnected by shafting 95 to secure equal movements. When the glassware is placed in position it engages an arm, not shown, to close a switch to operate an electro-pneumatic valve which feeds air to the cylinders which move the burners to the burning position and to another cylinder which engages the clutch C to start the ring 25 rotating. A timing device is also started and after the time necessary to turn off the moil this closes a switch in series with another switch operated by the ring 25 when heat has rotated to the position in which the open part faces the operator i.e. the position for loading and unloading. When this position is reached the electro-pneumatic switch is operated in the reverse direction to disengage the clutch C and retract the burners.

Title: Production of coloured photographic images
IPC: G03C7/28
Filed: 1941-12-05
Abstract: 553,752. Coloured photographic images. TULL, A. G. Dec. 5, 1941, No. 15708. [Class 98 (ii)] A coloured photographic image is produced in a silver halide emulsion layer diffusely dyed after exposure by developing a latent image in the layer, applying a bath of thiourea or thiosinamine to produce a silver salt complex image, applying a dye solution to dye the layer diffusely and precipitate additional quantities of the dye on the points of the complex silver salt image, and applying a dye bleach bath capable of performing selective imagewise destruction of the dye at the points unoccupied by the silver salt image. After development, the layer may be treated with aqueous solution of thiourea, which may contain potassium bromide or ferrocyanide. The layer may then be dyed with Metanil Yellow, and then treated with a dye-destruction bath containing thiourea, sulphuric acid, and hydroquinone. The combined silver salt may be left, or the dye may be precipitated with a dyefixing agent, e.g. barium chloride, a quaternary ammonium compound, or a basic dye, and the silver salt removed with hypo or Farmer's Reducer, either of which may contain a salting-out agent, e.g. magnesium sulphate. A negative dye image may be produced by development of the latent image, fixing, bleaching with a solution which may contain thiourea or thiosinamine (or if not following the bleaching by treatment in a bath of thiourea or thiosinamine), dyeing with an acid dye, and applying a dye-destruction-solution which destroys the dye at the points unoccupied by the silver salt, e.g. a solution containing chloric or bromic acid or both. The dye may be precipitated as before, and the silver salt removed. The process may be applied to the production of one or more colour component prints to be assembled in register to produce a multicolour record ; or to the colour processing of one layer of multilayer material of one layer of material having a plurality of emulsion layers on the other side of the support, or of one element of bipack material, the other support of which carries a plurality of emulsion layers.

Title: Signal delay circuit
IPC: H03B28/00
Filed: 1966-04-12
Abstract: 1,137,708. Pulse delay circuits. INTERNATIONAL BUSINESS MACHINES CORP. 12 April, 1966 [15 April, 1965], No. 15818/66. Heading H3T. . A pulse delay circuit comprises a monostable circuit which is triggered by both the leading and trailing edges of the input pulse and has a recovery time less than the duration of the input pulse, followed by a bi-stable circuit which responds to the trailing edge of the pulse from the mono-stable circuit and whose state depends on the level of the input pulse signal. In the figure, transistor 451 is normally off and 452 is conducting. The leading edge of a positive pulse on line 480 passes through diode 465 to turn transistor 451 on and start the mono-stable action. Similarly, after the circuit has recovered, the trailing edge of the input pulse passes through diode 467 to turn off transistor 452 and start another mono-stable cycle. The bi-stable circuit comprises crosscoupled transistors 490, 491 of opposite conductivity types, these being both saturated or both off. With no pulse on line 480 the trailing edge of the output of the mono-stable circuit forward biases diode 479 and turns on transistor 491 (if it is not already on), and consequently transistor 490 also. The output at 24 is thus at ground potential, signifying " 0 ". With a positive pulse on line 480 diode 479 will not be turned on by the trailing edge of the monostable output, but this will forward bias diode 473 and turn-off transistor 490 (if it is not already off) and consequently transistor 491 also. Point 24 is then at a negative potential, signifying " 1 ". The circuit may be used to follow the discriminator in the frequency-shift data transmission system of Specification 1,137,705, in which the minimum data pulse width is 5/3 ms., the delay introduced by the mono-stable circuit then being 1 ms.
