Title: Improvements relating to low pressure electric discharge lamps
Inventor: VAUSE ARTHUR SAMUEL
IPC: H01J61/72
Filed: 1957-02-06
Abstract: 822,510. Discharge lamps BRITISH THOMSON-HOUSTON CO. Ltd. March 28, 1958 [Feb. 6, 1957], No. 4112/57. Class 39(1). [Also in Group XXXVI] A low pressure metal vapour discharge lamp having the electrode 4 at one end spaced from the end wall 2 of the lamp envelope by a distance at least equal to the diameter of the lamp tube 1 is provided with a holder 5 having contacts 7 and a heat dissipating copper member 8. When the lamp 1 is fully engaged in holder 5 its metal end cap 2 is in contact with member 8 which cools it. This cooling effect plus that obtained by the spacing of electrode 4 at a distance from the end of the tube produces a cool region, the resulting condensation of metal vapour keeping the pressure of the vapour in the lamp envelope low enough to give optimum lighting efficiency. Specification 597,577 [Group XL] is referred to.

Title: Improvements relating to the transport of continuous web material
Inventor: STEVENS BROOKS JR
IPC: D06B3/34
Filed: 1968-01-26
Abstract: 1,217,958. Drying webs. RIGGS & LOMBARD Inc. 26 Jan., 1968, No. 4113/68. Heading F4G. [Also in Divisions B8 and F2] A web-guiding roller 53 is journalled in bearings such as 43, 46, Fig. 1, for free rotation about its axis, and at least one of the bearings 46 is supported in another bearing 47 and is driven so as to reduce frictional drag by the first bearing on the roller. The drive to the bearing 46 is through a variable speed unit 70, Fig. 7, enabling the bearing to be rotated in a desired and selected angular direction and to increase or decrease its speed relative to the web speed. The arrangement may be employed in a textile drying machine (as shown in Fig. 8) or in a textile washing machine as shown in Fig. 7, wherein the web 21 passes through a number of tanks 22, 23, 24, there being an expander role 32, a pair of driven squeeze rolls 33, 34 or 35, 36, and a driven dancer roll 38 controlling the web tension, between each pair of tanks. Fixed axis rollers 25-31 are provided in each tank to guide the web in a festoon arrangement, and, as shown, the outer parts of the bearings of the rollers, preferably at both ends of the rollers, are driven by sprocket and chain devices 62, 71 from the variable speed unit 70 which is connected to the driven squeeze rolls 35, 36. The immersed rollers 28-31 are hollow and of such a weight, that the upward pull of the web and the force of buoyancy balance the weight so that there is substantially no load on the bearings or only a slight downward pull on the web. If the upper rollers 25-27 are also immersed in liquid in the tank, the buoyancy force is arranged so that the rollers exert a slight upward pull on the loops passing thereover. In the case of drying apparatus (Fig. 8), a series of rollers similar to the rollers 25-31 guide the web through an oven heated by steam coils. Modified forms of driven bearings are described (Figs. 4, 5, not shown).

Title: Electrical testing of electric switches
IPC: G01R31/333
Filed: 1961-02-03
Abstract: 894,107. Testing switch-gear. SIEMENSSCHUCKERTWERKE A.G. Feb. 3, 1961 [Feb. 3, 1960], No. 4264/61. Class 37. In an arrangement wherein the switch 1 to be tested and an auxiliary switch 2 are connected across a source 3, which provides through transformer U1, high current at a low voltage, the switch 1 is connected also to a high-voltage supply derived from the same source 3 by a transformer 5, the arrangements being such that the two currents pass through zero at the same or nearly the same instant. The currents and voltages are made co-phasal by the inductances 6, 7, the condensers 8, 9 and the transformers 4, 5. In a modification described with reference to Fig. 3 (not shown) condenser 9 is omitted and the secondary connections of transformer 5 are reversed. The arrangement simulates the condition when opening a capacitive load, i.e. unloaded lines or condenser batteries. The current in the switch 2 is arranged to reach its zero value a little earlier than the switch to be tested. The restriking voltage up is made approximately equal to that set up under working conditions by choice of the voltage U2 and of the value of condenser 8. A resistor may be connected in series with condenser 8 in order to ensure that the arc in switch 2 extinguishes before that in switch 1. In an arrangement wherein the test power is developed in a threephase generator 3, Fig. 4, the high current is developed from one phase, and the high voltage from across the other two phases, the currents produced being 90 degrees out of phase. Condensers 8, 8<1> are connected in series with switch 1 and the latter is shunted by a spark-gap device having an auxiliary electrode 16 connected to a resistance 18 through a condenser 17. A further spark-gap 19 connects the resistor 18 in parallel with the switch under test. The arrangement decreases the re-striking voltage in a manner described with reference to Fig. 5 (not shown). The contacts of the switch under test may be in a pre-set position and initially bridged by an ignition wire. The test may be mains energized.
Patent GB-801424-A (GB)
Title: Process for the manufacture of titanium tetrachloride
IPC: C22B34/12
Filed: 1957-02-08
Abstract: Titanium tetrachloride is prepared by heating a titanium oxide containing material with elemental hydrogen or carbon at 1200 DEG  C. or above to evolve water or carbon monoxide which is removed, and thereafter contacting the solid residue with gaseous hydrogen chloride at 650 DEG  to 1100 DEG  C. to form titanium tetrachloride. Both the reduction and chlorination steps may be effected in fluidized beds but static or expanded beds may be employed. Fluidization may be effected by inert gases such as nitrogen or carbon dioxide or by reducing gases particularly hydrogen which is formed in the chlorination step.  When carbon is employed it preferably constitutes at least 5 per cent by weight of the mixture, the particle size of which is from 50 to 300 microns. Excess coke or carbon may be removed after the reduction step by dispersing the reduced material in bromoform and separating the lighter bromoform phase containing the coke.  The process is preferably carried out in a cyclic manner whereby the titaniferous material is alternately treated at 1200 DEG  to 1600 DEG  C. in the presence of carbon or hydrogen and with hydrogen chloride at 650 DEG  to 1100 DEG  C.; such a cycle may be applied to a batch of titaniferous material or a continuous cycle may be set up. According to examples, a mixture of rutile and petroleum coke was heated in a static bed at 1400 DEG  C. and the evolved carbon monoxide withdrawn.  The residue was stirred with bromoform to remove the coke and then treated with hydrogen chloride at 800 DEG  to 1000 DEG  C. to evolve titanium tetrachloride and elemental hydrogen.  Further examples relate to the reduction of a rutile/coke mixture with hydrogen at 1400 DEG  C. and chlorination at 800 DEG  C., both operations occurring in a fluidized bed.
