Title: Improvements relating to casting ladles
IPC: B22D41/14
Filed: 1961-12-19
Abstract: <PICT:0986129/C6-C7/1> A ladle for casting molten metal has a taphole at its base communicating with a transverse passage in which is a slidable push-rod, capable of initially closing the tap-hole.  The rod is made of a material which just melts at the temperature of the molten metal to be contained; it may consist of metal to be alloyed therewith, or of alloying elements in a suitable container.  To prevent premature discharge the rod is initially protected by a compacted layer of insulating material.  As illustrated in Fig. 1, tap-hole 6 is initially closed by rod 9 sliding in passage 8.  This type of tapping device is claimed to be particularly advantageous in that method of vacuum treatment wherein hermetically sealed to the base of the ladle is an evacuated chamber through which the metal is tapped.

Title: Method of and apparatus for correcting tube eccentricity
IPC: B21C1/24
Filed: 1962-12-03
Abstract: 955,060. Drawing tubes. BABCOCK & WILCOX CO. Dec. 3, 1962 [Dec. 4, 1961], No. 45496/62. Heading B3P. An apparatus for reducing the eccentricity of wall thickness of a metal tube comprises an annular reducing die, means for mounting said die in a fixed position with the axis of the die parallel to the axis of the tube and a mandrel mounted for swivel movement about a fixed point relative -to the die. The mandrel 21 comprises a body 22 and a bolt 23 which has a flange 24 substantially at the midpoint of the body 22. The head of the bolt has a curved inner surface 28 which co-operates with a similar surface on a sleeve 31. The threaded end 25 of the bolt engages a mandrel support rod 27 and there is a washer 32 between the body 22 and the support rod. There is clearance between the body 22 and the flange 24 and when a tube 40 which has a thick wall portion 41 and a thin wall portion 42 is drawn between the mandrel and a die 10, the mandrel body 22 tilts and exerts a greater outwardly radial pressure on the thick wall part 41 than on the thin wall part 42 and so reduces the eccentricity.

An exposed photographic silver halide material is automatically transported at substantially constant speed successively through developing, stabilizing, fixing and washing stations; the material being treated at said stabilizing station 'with a liquid medium containing a stabilizing agent which forms with unexposed silver halide a lightinsensitive complex or complexes which would not be completely removed by washing with water, e.g. potassium and ammonium thiocyanate, thioglycolic acid, thiosalicylic acid, monothiohydroquinone, various thioureas and thiosemicarbazides, and the material while still wet with said stabilizing medium being treated in said fixing station with a thiosulphate fixer. The latter converts the said complexes to a modified form in which they become removed by an aqueous wash at said washing station. The developing agent may be a hydroquinone/3-pyrazolidone developing agent contained in the silver halide material itself and the developing medium may then comprise an alkaline aqueous medium. The processing may comprise additional treatment stations e.g. stopping and drying. The processing stations may comprise trays with doctor knives or rollers for removing surplus liquid, and the transport may be by rollers and guideways. The developer or developer-activator solution may be applied by lick-rollers or by spraying or spreading a measured dose, or the developer or activator solution may be contained in a pod attached to the light-sensitive material, said pod being ruptured and the solution being spread at the development station.

Abstract: 1375844 Photo-electric control of display brightness CENTRE ELECTRONIQUE HORLOGER S A 10 Oct 1971 [30 Oct 1970] 47044/71 Heading G1A [Also in Divisions G3 and H2] In an electronic timepiece having an oscillator, a counter, and a display wherein selected electroluminescent elements are illuminated via a decoder circuit, a photovoltaic battery is arranged to act as the sole energy source for the display when ambient illumination exceeds a threshold level and a non-photovoltaic battery provides additional power for the display below this threshold level. Fig. 5 shows an arrangement using a photoelectric battery 46 to charge a capacitor 47 supplying energy to luminescent diodes 63 of the display. The display is controlled by electronic switches 66 triggered by decoder 67 in response to the output of oscillator 54 and counter 55. As long as the voltage on the capacitor 47 exceeds that of an upper reference source 51, the output N 1  of comparator 50 is unity and hence signal N 1 , being zero, keeps gate 61 closed and switch 65 open. No power is therefore drawn for the display from a capacitor 56 charged by chemical battery 53. If the leval of ambient illumination falls so that the signal N 1  changes to unity, the gate 61 and thus the switch 65 fall under the control of a modulator 59 which operates in response to a signal E from an ambient illumination detector 60 and a signal H 1  from the counter 55. As long as the voltage on the capacitor 47 is still above that of a lower reference source 49 so that the output N of comparator 48 is unity, switch 64 is operated in response to a further signal H from the counter fed to an asynchronous sequential logic circuit 52 so that some power is still drawn for the display from the photo-electric battery 46. The battery 53 supplies additional power so that the mean display brightness is varied and visibility is ensured over a range of ambient illumination. If this illumination falls further so that the comparator output N also changes to zero, the switch 64 remains permanently open, disconnecting the photo-electric battery 46. The battery 53 continues to supply the display through the switch 65 which is controlled so that the brightness is reduced with that of the ambient illumination down to a minimum threshold brightness. The display may be pulsed at intervals which are short compared with visual persistence of the human retina, or alternatively the minutes display can be pulsed at one second intervals. In a simpler arrangement, Fig. 4 (not shown) the photo-electric and chemical batteries (32, 44) are connected by a resistor (45), and a storage capacitor is connected at the output of the photoelectric battery. The chemical battery supplies make-up power to the display until a high level of illumination is reached above which it is recharged. At very low light levels, the photo-electric battery may be disconnected.
