Filed: 1934-02-26
Abstract: 422,996. Vehicle-suspension systems. BROUSSOUSE, F. L., Logis du Plantier Garat, Charente, France. Feb. 26, 1934, Nos. 6232 and 6233. Convention dates, Feb. 24, 1933 and June 29, 1933. [Class 108 (ii)] A vehicle is suspended on longitudinally arranged laminated springs connected to the axle 12 by means of a cradle comprising a bed plate 5 and pivoted links 8, 9 such that the cradle can make lateral dis - placements combined with an elementary rotation. The springs may be slung under the axle and the length and angle of convergence of the links may be combined with the width of wheel track, diameter of the wheels and minimum clearance above the ground so that the suspended mass will oscillate, approximately, about an axis situated at the level of the ground.

Abstract: 1,112,384. Fuelling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 Feb., 1966 [12 Feb., 1965; 1 Oct., 1965], Nos. 6264/65 and 41856/65. Heading G6C. [Also in Division B8] A reactor refuelling machine has gripping jaws 11 pivoted at 22 which are held in engagement with a fuel element 13 by a guide tube 12 until the element is completely withdrawn within the tube. The jaws are moved to a disengaged position at the lower end of the tube 12 by slots 28 and cam surfaces 31 which cooperate with rollers 26, 30 pivoted on the jaws. The jaws are moved up and down the tube by a screw-and-nut 14, 16 connected by a latch 17, 17a. Alternatively, Fig. 1a (not shown), the jaws may be connected to the nut by a sliding latch (101) moved into engagement with grooves (105) in the nut by a scroll cam (104) and a pin (103). This connection permits pivotal movement between the nut and the latch about a horizontal axis, thus minimizing the danger of jamming. The screw is driven through a pivoted universal joint provided with meshing pegs (134). When the fuel element is completely within the tube 12 a safety catch (38), Fig. 3b (not shown), is moved below the element by a rod (35) which is raised by the nut. The tube 12 is positioned over the fuel elements by parallel links (67), Figs. 3a, 3b (not shown), mounted on a rotatable pillar (70). The refuelling machine may be used with the magazine for fuel assemblies which forms the subjectmatter of Specification 1,112,383.

Class 87(i) [Also in Groups XI and XXXVI] A reinforcing wire to be embedded in a ceramic body is coated with a substance which shrinks both during drying and firing of the ceramic. The coating is preferably of a material such as gelatine or collodion or a mixture of these made up into a nitrogen-base lacquer, which expands on being brought into contact with the ceramic due to its absorption of moisture therefrom and then undergoes a reduction in cross section during the dry-' ing of the ceramic which is substantially equal to that which occurs in the surrounding ceramic. During the firing of the ceramic the coating is at least partly destroyed or dispersed, leaving a space to allow for the expansion of the metal element and the shrinkage of ceramic which occurs during firing. The coating may also include a substance such as graphite to give chemical protection to the metal during the drying and firing of the ceramic.

A three - phase squirrel - cage induction motor 1 is started by closing push - button T1 to energize the coil of contactor K1 through contact K2-2, the stator of the motor being initially connected to the supply source through adjustable series resistance R. An overload release relay U having a time delayed release contact U1 is not included in circuit during starting period. The closure of self-maintaining contacts K1-1 allows the push-button to be released. After a period of delay, contacts K1-2 close, whereupon the coil of contactor K2 is energized through contacts T2, K1-2, and U1 so that the resistance R is by-passed and the motor connected to the supply-lines through relay U. The contacts K2-2 open after a period of delay to de-energize the coil of contactor Kl, the contactor K2 being held operated by contacts K2-1 when contacts Kl-2 open.

Abstract: 221,741. Schr÷der, E. March 14, 1924. Heating by electricity.-An electric heating machine for pins, rivets, bolts, &c., has an annular secondary rotatable about a core which carries the primary winding. The articles are automatically held and released by the secondary during its rotation. An annular iron core K is fixed on a support U and carries the primary winding P. The secondary comprises a. tube R, two discs S, S, and contacts E, E, with holders H, H for the articles to be heated. The discs S has radial slots so that the tongues which carry the holders H are sufficiently flexible to be moved slightly axially to enable the contacts to be brought together. A fixed cam track L is engaged by rollers I carried by the contacts E<1> in order to close the holders H on the pins to be heated. Rollers II on the contacts E<2> then engage the cam track to move the holders H axially towards one another to complete the circuit and heat the pins. This is effected automatically as the pins are fed to the machine at one point of its rotation, and are released after a partial rotation at such a speed that they are heated to the required temperature. A press or the like which utilizes the heated articles may automatically control the rate of rotation of the secondary.

Abstract: 253,575. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), and Lowry, L. P. March 12, 1925. Drawings to Specification. Semi-automatic exchange systems.-In a system in which an outlet relay group temporarily associated with an operator's keyboard is provided with a finder switch which hunts for an assigned trunk, the test contact of the latter being marked by the removal of earth, the test wiper of the finder is of the bridging type so that the switching relay which is short-circuited over earthed contacts during hunting shall not operate prematurely during the passage from one set of contacts to another. A relay in the trunk circuit which is to be operated by earth sent back over the test terminal from the outlet relay group is made slow to energize so as not to be operated prematurely when the test wiper bridges the marked test contact and a previous earthed contact. The invention is described with reference to apparatus which forms a part of the complete system described in Specification 254,183. Specifications 253,574 and 255,130 also are referred to.
