[Class 38 (i)) [Also in Groups XI, XXXV, and XXXVII] In a signal lamp having a plurality of electric light sources 30 and means automatically operative on failure of the positioned source, to move another one into position where it is connected in the circuit, the lamps 30 are mounted on an endless carrier belt 15 disposed vertically in the casing 10 and supported by two rotary supports 16, 17. The belt consists of flat pivoted plates each carrying a lamp 30, while the supports 16, 17 comprise horizontal rods 23, 52 extending between discs 20, 21 and 50, 51 respectively. Each lamp 30 is held in its carrier plate 15 by three headed studs 31 engaging in slots in the focusing flange 33 of the lamp, the latter being pressed against the stud heads by bent-up spring tongues 32, Fig. 3. The centre terminal of the lamp is connected in the supply circuit through strip 35 and shaft 24 while the connection to the side terminal is made through plate 15, rods 23, and metal disc 22, the latter being secured to the disc 21 which is of insulating material and provided with four equally spaced sunk contact strips 36 connected to the disc 22. The strips 36 are so arranged that, when a lamp 30 is in correct position in relation to the lens 12, one of them is engaged by a contact 38 on the end of a spring 39 secured on a bolt 42 ; when the carrier begins to move to position a now lamp the contact 38 is forced out of the groove 37 into engagement with a contact 40 on the end of a spring 41 secured on a bolt 43, thus closing a circuit to the carrier driving motor 55.
Patent GB-279819-A (GB)
Title: Catalytic apparatus
IPC: B01J8/02
Filed: 1927-10-11
Abstract: 279,819. Seldon Co., (Assignees of Jaeger, A. 0.). Oct. 27, 1926, [Convention date]. Catalytic apparatus. - Heat exchanging elements are so arranged in a catalytic chamber that a substantially uniform cooling is produced in the catalyst throughout any horizontal crosssection of the catalyst layer. The desired effect may be produced by spacing tubes carrying the reaction or other cooling gas closely towards the centre of the mass than at its periphery or by varying the relative velocity of the gasses passing through outer and inner tubes. Metallic granules &c. or wire mesh may be interspersed with the catalysts. In the construction shown in Fig. 1 simple tubes 6 introducing gases to the catalytic material are spaced more closely at the centre of the chamber and in the construction shown in Fig. 2 the same arrangement is employed with concentric tubes 13, 14. The variable intensity of cooling effect may be obtained with equally spaced tubes by varying the gas velocity from tube to tube e.g. by inserting appropriate throttling devices 15, 16, Fig. 5, in certain tubes. A further variation in cooling effect may be obtained by variation in the effective length of the tubes produced for example by providing perforated portions. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification shown in Fig. 6 (Cancelled), in which the cooling gases pass through horizontal tubes 23 which are spaced closer together at the upper part of the catalytic mass where, on account of the greater concentration of the reacting gases near their inlet, the evolution of heat is greater. A similar effect may be obtained by varying the velocity of the gas. The gas employed may be that taking part in the reaction or may circulate in a separate cooling system. In apparatus such as that shown in Fig. 9 (Cancelled), and forming the subjectmatter of Specification 305,6.36, cooling may be aided by a liquid or solid reagent or neutral substance introduced through pipes 45 so that it vaporizes on the walls of tubes 35, gaseous components being introduced through tubes 36, 37. This subject-matter does not appear in the Specification as accepted.

[Class 38 (v)] In switches of the kind employing a conductive liquid in a rotary container 6 with rotating electrodes dipping into the liquid, which forms a cylindrical layer 14 by centrifugal action, the radial level of the liquid is regulated by means depending on the kinetic energy of the rotating liquid. In the construction shown, a pipe 21 disposed in a direction opposite to the direction of rotation of the liquid dips into the liquid so that excess liquid in the container is forced into the pipe and conducted to a cooler 22 formed as an annular chamber at the top of the casing 1 of the switch. A supply pipe 23 conducts liquid back from the cooler to the container 6. A float 27 automatically opens a pipe 28 leading to a supplementary container if the level of the liquid in the cooler 22 falls, so that losses due to evaporation or spraying of the liquid are replaced. In another arrangement, the liquid is caused to overflow on to an inclined plane in the form of a cone shaped plate up which the liquid creeps till it reaches a container from which it is cooled and returned to the rotating container.
