Title: Improvements in or relating to electric relays of the induction type
Inventor: FAVELL BRIAN JEFFREY
IPC: H01H53/10
Filed: 1957-05-01
Abstract: 860,535. Induction relays. REYROLLE & CO. Ltd., A. May 1, 1957, No. 13879/57. Class 38 (5). A relay with normally-open contacts has a contact-actuating lever pivoted about an axis spaced from the axis of the induction element which operates the lever through a cam device arranged so that, until the contacts touch, the only load on the induction element due to the lever is the lever inertia and friction. The lever F, G<SP>1</SP>, G<SP>2</SP> is pivoted about a spindle F<SP>1</SP> parallel to a spindle A<SP>1</SP> carrying the induction disc A and biased to the position shown by a helical spring K. A wheel-shaped member C fixed to the disc A carries the can D having a slot E for a pin F<SP>2</SP> on the end of the lever F. During about 300 degrees of rotation of the cam D the pin F<SP>2</SP> is in an arcuate part of the slot E and the lever F is not moved. During the next 30 degrees the pin F<SP>2</SP> is in the slot part E<SP>1</SP> and the lever F, G<SP>1</SP>, G<SP>2</SP> is quickly moved to a position where contacts G<SP>3</SP>, H<SP>1</SP>, H<SP>2</SP>, and G<SP>4</SP>, H<SP>1</SP>, H<SP>2</SP> are about to close. During the next 20 degrees the pin is in the slot part E<SP>2</SP> and the lever is slowly moved against the contact-spring pressure. The starting-point of the disc and hence the time-delay can be varied by rotating a setting-disc M carrying a stop (not shown) against which an arm M<SP>1</SP> on the spindle A<SP>1</SP> is urged by the spring K. The lever F may carry a projection N<SP>2</SP> (Fig. 5) which when the contacts are closed releases a catch N<SP>1</SP> on a pivoted indicator spindle N allowing an indicator N<SP>3</SP> to fall. The spindle N may carry one or more members which on operation open or close additional spring-biased contacts (Fig. 6, not shown). Fig. 7 shows a modification wherein a fixed contact Q<SP>4</SP> is urged against a stop Q<SP>6</SP> by a spring Q<SP>5</SP>, the movable contact Q<SP>2</SP> having a slot Q<SP>1</SP> for a pin Q carried on the lever F, G<SP>1</SP>. Fig. 8 (not shown) illustrates an alternative cam allowing about 590 degrees of movement for complete operation. Fig. 9 shows a contactactuating lever V carrying two rollers W, X engaging two complementary cams S, T having shapes corresponding to the outer and inner surfaces respectively of the slot E.

Title: Method and apparatus for the manufacture of glass beads
IPC: C03B19/10
Filed: 1965-04-01
Abstract: <PICT:1066684/C1/1> In a process for the manufacture of glass beads a film of molten glass is formed on a rotating member and is then dispersed by centrifugal force to form the glass beads. Molten glass 14 is controllably fed through an orifice 16 in a tank bottom on to a horizontal centrifugal member 1 having a water-cooled vertical axle 2.  The member 1 is contained within a chamber 8 heated by burners in tubes 11, 12.  The molten glass forms a film on the member 1 and continuing under the action of centrifugal force disperses to form small beads which are thrown through openings 18 in the sidewalls of chamber 8 into cold collecting vessels 19. Glass may be fed to more than one point on the member 1 simultaneously.  The molten glass may be fed through a tank side wall 161 (Fig. 2, not shown), on to a portion of the member 1 displaced from its centre.  The centrifugal member may be flat and horizontal, vertical or inclined; may have a circular edge, a serrated edge, an upturned serrated edge; may be conical, concave, cylindrical; or may be formed as a disc with a concave rim.  If the member 1 has a horizontal axis a portion of the member may be immersed in the molten glass, and the member may comprise a plurality of discs.  Glass may be fed to both sides of the member either directly or through perforations therein, e.g. the partially immersed conical member 40 (Fig. 17, not shown) which has a recessed portion 42, the apex 44 of which is above the glass level, glass being forced up the inside through apertures 46.  The centrifugal member may be made of a ceramic or a metal such as molybdenum or tungsten, and in cases where glass is fed to one side only the other side may be protected from oxidation by a protective atmosphere.

Title: Improvements relating to the purification of lactams
IPC: C07D201/16
Filed: 1957-05-02
Abstract: Lactams obtained by the Beckmann transformation of alicyclic oximes with strong sulphuric acid and subsequent neutralization and preliminarily purified, e.g. by extraction with organic solvents or by distillation, are further purified after removal of water by evaporation of volatile organic impurities from the solid lactam. The process may be carried out under reduced pressure and in the presence or absence of an inert gas, or may be continuous. The evaporation is best carried out by heating the lactam in finely divided form, e.g. as powder or flakes, with stirring under high vacuum at a temperature near its melting point.  It may be effected by passing inert gases, such as nitrogen, air or carbon dioxide, through the solid lactam at normal or reduced pressure. The temperature should be as high as possible below the melting point of the lactam.  The continuous process may be carried out by passing the lactam in a thin layer, e.g. by solidifying distilled crude lactam, through a long vessel heated by infrared rays under high vacuum; if inert gases are used a moving gate is employed. In examples caprolactam and methyl-caprolactam are purified, other specified lactams being o -valerolactam, o -oenantholactam, o -caprolactam, o -decylic acid and o -undecylic acid lactams.
