Abstract: 362,885. Colour photography. CLAUDE NEON LIGHTS, Inc., 41, East 42nd Street, New York, U.S.A.-(Assignees of Beck, L. L. ; 27, Stonleigh Park, Westfield, New Jersey, U.S.A.) June 5, 1930, No. 17433. Convention date, June 26, 1929. Void [Published under Sect. 91 of the Acts]. [Class 98 (ii).] To produce white light for photography with panchromatic and orthochromatic films, the red rays from an electric discharge lamp containing neon are blended with blue rays from a discharge lamp containing mercury with or without neon or argon &c., the blue rays passing through a yellow or amber screen. Colours are not distorted, green photographing as a lighter grey than blue. The tubes operate at low voltages and high currents and have low-voltage electrodes of the hot or alkali metal types. The mercury tube may have an envelope of uranium or yellow glass or may be coated with yellow gelatine and is preferably so placed that the red rays from the neon tube pass through it and blend with the blue rays to avoid colour fringes. The two tubes may be placed adjacent or may be constructed one within the other as in Fig. 2, the intensity of the light emitted by one or both tubes being controlled by adjustable resistances or other impedances 10 in circuit with the tubes. In a modification, Fig. 3, a large neon tube 15 is surrounded over part or the whole of its circumference by mercury tubes 16 in a common reflector 18.

Title: Device for piling up glass objects on a mandrel
IPC: C03B17/04
Filed: 1931-06-17
Abstract: 363,966. Drawing glass tubes and rods, NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT EXPLOITATIE VAN UITVINDINGEN, 64, Leuvehaven, Rotterdam, Holland. June 17, 1931, No. 17589. Convention date, June 27, 1930. [Class 56.] Relates to the method of making tubes or rods in which preformed blocks are piled on a mandrel having an enlarged lower end, and the blocks are heated so that the glass flows over the enlargement of the mandrel and is drawn away as a tube or rod. The invention consists of a method of replenishing the pile of blocks, as the glass is melted, without disturbing the position of the mandrel. The mandrel 1, which may be vertical or inclined and either stationary or rotated, is supported by a number of tongs 5 which engage parts 1a of the stem of the mandrel of reduced diameter. The tongs are pivoted to a standard 13 and are drawn together by springs 23. They are kept in alignment by screws 6, passing through their front ends, which engage a rod 7 fixed parallel with the standard 13. When a glass block 35 is threaded on the upper end of the mandrel, it must be moved downwards without disturbing the position of the mandrel. For this purpose, the block is supported on a fork 2 the tail end of which slides into a wedgeshaped cam 20 that screws on to a rod 16. By rotating the rod 16 by means of a handle 17, the wedge 20 and the fork 2, and therefore the glass block 3, are moved downwards. The wedge 20 opens each of the tongs 5 in turn without disturbing the others, and the springs 23 close the tongs again after the wedge has passed. When the glass block 3 reaches the lowest position to which it can be moved, the fork 12 is moved inwards towards the wedge by means of a lever 25 which engages a stop 24 on the fork. The wedge and the fork can now be raised again by reversing the rotation of the rod 16.

Title: Improvements in or relating to systems for controlling the heating of buildings
Inventor: SYMONDS WILLIAM PERCIVAL LAURE
IPC: G05D23/24
Filed: 1963-05-06
Abstract: 1,038,066. Automatic temperature control systems. MINISTER OF PUBLIC BUILDINGS AND WORKS. June 17, 1964 [May 6, 1963], No. 17769/63. Heading G3R. In an automatic space heating system controlled by the ratio between outside ambient temperature and flow pipe temperature, an overiding boost control is incorporated to reduce the boost as the ambient temperature increases. The ambient and flow pipe temperatures are sensed by thermistors E1, E2 connected in a bridge circuit containing a magnetic amplifier control winding MA1, the main windings of which vary the potential across resistor R7, which added algebraically to the potential across resistor R8 energizes one of relays R x 7, R x 8 to drive the reversing motor M to control the flow pipe temperature. Boost is controlled by the output from a rectifier R x 2 fed from a tapped transformer W6 and which is further varied by a resistor VR1. By closing a switch SW2 infecting a potential into resistor R5 the arrangement may be changed to a lower heating rate for, say, night use.
