Abstract: 1,212,851. Glazed pottery. HORNSEA POTTERY CO. Ltd. 2 Jan., 1968 [23 May, 1967], No. 23841/67. Heading C1M. Ceramic articles are glazed and decorated by applying by direct screening to a biscuit article, preferably having a water absorption capacity of between 15 and 20% by weight, a design glaze dispersed in a resist medium consisting of a drying oil alkyd resin, or a drying oil modified thixotropic alkyd resin or both, and a light lubricating oil, followed immediately or after drying by immersing the screened article in a water-suspended background glaze and subsequently firing. The design glaze is preferably applied through a nylon or steel mesh and may consist of ceramic colour and a glaze frit or flux. The glazed areas are said to stand out in relief against the printed pattern.

Title: Traffic control telephone system used on railways
IPC: B61L25/04
Filed: 1960-07-11
Abstract: 954,062. Selective signalling systems. M.S. VISVANATHAN, and P.S. PATHARE. July 11,1960, No. 24158/60. Heading G4H. Remote station selection apparatus comprises a plurality of push-buttons A, one for each station, and each operating a corresponding station selection relay SSR, each of which has a set of contacts connected to contacts of a motor-driven impulsing unit 1. In the embodiment described, a station is called by a sequence of 3 groups of impulses, the number of impulses in each group being variable, but the total number of impulses in a complete call signal being 17. Each relay SSR has 5 contacts, the first of which C1 is a stick contact. To produce code signal 3, 7, 7, for example, contacts C 2 , C 3  supply positive potential to contacts 3,14 of unit I, contact 25 of which is connected to the positive supply for all call signals. Contacts C 4 , C 5  supply negative potential to contacts 7, 18 of unit I. When push-button A is pressed motor start relay MSR operates to open contacts M3 and also to supply power to motor MR which then rotates wipers CWC1, CWC2, CWC3 on shaft J. Wiper CWC3 contacts impulsing track H to energize transmitting relay TR during oddnumbered impulse intervals and release TR during even-numbered intervals, the polarity of the voltage applied across-line L 1 L 2  being different for the two states of relay TR. When contact 3 of unit I is reached by wiper CWC1, BRM operates to close stick contact RM2 and connect a positive supply to TR through break contacts RB1. Relay TR remains energised until CWC1 reaches contact 7 whereupon a negative potential is supplied to BRM which then releases and permits imphlsing of TR by CWC3 until contact 14 is reached by CWC2 when BRB is operated to close stick contacts RB2 and open contacts RB1 thereby disconnecting the supply to TR. Relay TR remains deenergised until CWC2 reaches contact 18 whereupon BRB is released and TR is impulsed by CWC3 until CWC1 reaches contact 25, when BRM is again operated to hold TR in the operated conditions. BRM is released when CWC1 reaches contact 31 but TR remains energized since CWC3 is then traversing continuous contact K. When the wipers have returned to the starting position, cam DW on shaft J opens contacts DCT to release relays AUX; MSR and stop motor MR. Release of MSR closes contacts M3 to return the main supply to the push-button panel and the system is ready for a fresh selection. A further "general call" push-button A1 is provided controlling-relay GC whose contact C2 supplies positive potential to contact 17 of unit I, enabling a continuous train of 17 impulses to be transmitted, to which all of the remote stations are arranged to be simultaneously responsive.

Class 65(2) [Also in Group XXXIV] In an elactromagnetically operated friction brake, the pivotal joints between shoecarrying levers 4, 5 and a base 6 comprise cylindrical segments 34 on the ends of the levers engaged in part-cylindrical sockets in the base. The joints are held in place by retaining pins 35 which project from the segments 34 into openings 36a formed in mounting plates 36 mounted on base 6. The bearing surfaces of each joint are lubricated by means of a pad 40 of absorbent material such as felt saturated with a suitable lubricant. Upon brake release pivotal movement of a lever acts to compress slightly the pad to permit some of the lubricant to flow into the joints. The pad also acts as a seal to prevent the ingress of foreign matter on to the bearing surfaces.

Title: Improvements in and relating to the production of skeletal glass catalysts
Inventor: VINCENT GEORGE CLARKSON
IPC: B01J37/08
Filed: 1954-08-25
Abstract: A skeletal glass catalyst in the form of a sintered aggregate is produced by fusing a mixture of materials containing a catalytically active ingredient to form a glass, heating the glass to cause separation into phases, reducing the glass to particles before or after the phase separation step, heating the particles to cause them to cohere to form an aggregate, and extracting from the aggregate at least part of at least one soluble phase.  The glass particles may be heated to a temperature sufficient to cause simultaneous separation of phases and cohesion of the particles.  Glass prepared from a mixture of alumina, silica, boric oxide, and an alkaline earth may be separated into phases by heating at 650 DEG -950 DEG C. for about 24 hours.  The aggregates may be produced in cylindrical or spherical shape by processes involving moulding or extrusion.  Extraction may be carried out with hot dilute hydrochloric acid.  Examples describe the preparation of catalysts from a glass containing alumina, silica, boric oxide, and calcium oxide; these catalysts are tested in the dibutylation of tertiary-butyl benzene to form benzene. Specification 765,468 is referred to.

[Class 38 (ii)] [See also Group XL] Continuous current is converted into alternating by means of mercury or other vapour discharge tubes having control grids so arranged that the tubes have a single breakdown characteristic. The anodes 14 of two tubes 1, 1<1> are connected by a commutating condenser 30 and the primary 27 of the output transformer. The mid-point of the primary 27 is connected through an inductance 33 and a switch 32 with the positive of the supply, the negative being connected with the cathodes 16. A circuit serving to impress a starting voltage on the grids 22 alternately is in shunt with the left-half of the primary 27, and consists of a condenser 31<1>, a resistance 32, and a transformer primary 33, the secondary 35 of which is connected through resistances 36 with the grids 22. A potentiometer 37 provides a positive voltage for the grids. As the current through the tube 1 and the left half of the primary 27 builds up, the secondary 35 causes a negative voltage to be applied to the grid of the tube 1<1>, so as to prevent a discharge. When the current through the tube 1 reaches a maximum, the voltage across the primary 27 decreases, and as a result the voltage across the secondary 35 decreases, and the grid of the tube 1<1> becomes sufficiently positive to allow a discharge to pass.
