Title: Spray nozzle
IPC: E03C1/08
Filed: 1974-01-22
Abstract: 1468961 Spray nozzle TELEDYNE INDUSTRIES Inc 22 Feb 1974 [4 Sept 1973] 8268/74 Heading B2F A spray nozzle includes a hollow housing having an inlet and a first group of spray discharge outlets 44; means in the housing defining a first passage in the housing extending from the inlet to the first group of discharge outlets: a valve member 54 mounted in a space affording part of the first flow passage operable by water flowing through the first flow passage to intermittently interrupt flow from the inlet to each outlet of the first group of outlets thereby to cause a pulsating spray to be discharged therefrom; the housing having a second group of spray discharge outlets 34 and means in the housing extending from the inlet to the second group of discharge outlets, the second flow passage bypassing the valve member and communicating directly with the second group of outlets whereby water flowing through the second flow passage is discharged from the second group of outlets in continuous non-pulsating streams. The valve member 54 comprises an annular turbine unit which is rotated by fluid flow through tangentially-directed passages 50 and thus interrupts the flow to units of the first group of outlets 44 as a flat plate portion 56 of the valve member moves over surface 42 containing outlets 44. The second flow passage is formed by channels 48, which bypass the valve member 54, and grooves 34 formed in lower housing 20, which are sealed to form orifices by a washer 36 fittting inside housing 20. Water may be directed through these two passages and through a third passage, which passes through the centre of the valve member without substantially affecting its rate of rotation, by a flow-directing plate 62 which has arcuate openings corresponding with the three flow passages. Flow through the passages is controlled by an annular shutter plate 84, moved by the user of the device by means of a control ring 112 and a gear mechanism, and which has blades for closing the openings allowing continuous flow alone, a mixture of continuous and pulsating flow or pulsating flow alone. Reference has been directed by the comptroller to Specification 1430123.

Title: Method of rendering titanium dioxide films electrically conductive
IPC: H01B1/08
Filed: 1957-03-18
Abstract: A transparent film of titanium dioxide, deposited on a support surface is rendered electrically conductive by heating the supported film in vacuo at 200-700 DEG  C. for 5 to 20 minutes.  The resistance of the film may thus be reduced from 100 megohms per square to 60 ohms per square.  Suitable supports are quartz or glass.  The film may be formed by spraying titanium tetrachloride vapour over the surface heated to 200-250 DEG  C. in a moist atmosphere, and may have a thickness of 0.1 to 0.7 microns.  The absolute pressure during the heating of the film should be below 100 microns Hg and preferably below 1 micron.  An example refers to a 0.4 micron thick TiO2 film on a glass support heated at 600 DEG  C. for 12 minutes under a pressure of 1 micron Hg. Conductive TiO2 films may be used as charge dissipating electrodes in cathode-ray tubes, in electrolumin escent cells and on area heat sources.  Specification 738,285, [Group XL (a)], is referred to.

Abstract: 1459252 Resistors DANFOSS AS 28 Feb 1974 [1 March 1973] 9033/74 Heading HIS [Also in Division H5] A silicon carbide resistor body, e.g. for use as a heater, containing free silicon in its terminal portions only, is made from a member composed throughout of silicon carbide containing free silicon by subjecting the portion between the terminal portions to an etching process to remove the free silicon. Preferably the portion which is etched is thinner, and the terminal portions masked during etching in a HF-HNO 3  mixture. In one method silicon from a melt rises upwards by capillary action in a porous block consisting of SiC granules and colloidal graphite with which the silicon reacts to form SiC. If silicon is added to the melt silicon monoxide vapour is produced and reacts with the graphite to give a highly porous surface layer in which the silicon concentrates. The reaction, performed e.g. at 1500‹ C. in vacuo is terminated while the free silicon is still concentrated at the base of the body and hence in the terminal portions if the body is of appropriate form e.g. is U-shaped or consists (Fig. 3) of a tube with longitudinal slots extending from one end to spiral slots 12, 13 defining a resistance path of double spiral form. The average concentration of free silicon in the terminal portions may be 2-20% by volume and the surface concentration up to 50%. Contacts of silver, aluminium or gold-antimony alloy are conventionally deposited and then heated to form a eutectic alloy with the silicon.
