Title: A method of producing titanium tetrachloride
IPC: C01G23/02
Filed: 1966-12-29
Abstract: TiCl4 is subjected to a heat treatment at a temperature > 250 DEG  C. (preferably > 600 DEG C.) in order to effect decolourization and colour stabilisation. The TiCl4 is prepared by treating a titaniferous ore with a chlorinating agent in a chlorinating zone; the chlorinated products are removed from the zone and TiCl4 seperated from the other metallic chlorides formed. The TiCl4 may be treated with at least 0.001 parts by weight of an oxidizing gas, e.g. Cl2, O2, COCl2, O3 and nitrogen oxides, at a temp. above its boiling point, preferably during the heat treatment.  The heat treatment may take place by passing TiCl4 vapour through a heated particulate bed of solid inert particles, e.g. of alumina.  The TiCl4 formed may be separated from other metallic chlorides by scrubbing with an unsaturated oil before or after heat treatment.

Title: Improvements in or relating to Electrical Supervisory Systems
IPC: G08B23/00
Filed: 1967-12-21
Abstract: 1,182,700. Semi-conductor switching circuits. HONEYWELL Inc. 21 Dec., 1967 [23 Dec., 1966], No. 58170/67. Heading H3T. [Also in Division G4] A supervisory system comprises a central station feeding current via at least one pair of conductors such as 37, 37<SP>1</SP> to at least one sensor 40, each pair being connected to a separate trigger circuit responsive to both open circuit and short circuit conditions in the respective pair. As shown, current from a full wave rectifier 14 is filtered at 15, 32 and regulated by a Zener diode 34 before being fed via a line 37, 37<SP>1</SP> to a remote station having fire or burglar-responsive contacts 41, 42, 43 and a Zener diode 44. The current in line 37, 37<SP>1</SP> normally maintains transistor 52 conductive so that S.C.R.1 cannot be triggered until an open circuit occurs in the line when transistor 52 becomes non-conductive, breaking down Zener diode 56 and triggering S.C.R.1 which energizes a warning lamp 24 and relay K2 and triggers S.C.R.3 which operates a buzzer 22a and further relay Kl. A short circuit on the line similarly breaks down Zener diode 56, providing a similar action. The buzzer 22 may be made silent by opening contacts 16a. The circuit may be reset by opening contacts 20a or, if link 18a is disconnected, the circuit is automatically reset by the next half cycle of the alternating voltage input. Further circuits 11, 12 similar to circuit 10 may be included to monitor other lines

Title: Beam current limitation in cathode-ray tubes
IPC: H04N5/14
Filed: 1966-12-30
Abstract: 1,146,180. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Dec., 1966 [31 Dec., 1965], No. 58345/66. Heading H4T. The average beam current of a cathode-ray tube 1 is limited to a predetermined maximum value by means of an RC circuit 15, 16, connected between earth and the negative pole of the EHT supply, and so proportioned that, when the beam current reaches such maximum value, the voltage developed across the circuit (of negative polarity with respect to earth) causes diode 17 to conduct so that the control grid 3 then follows such voltage and prevents further increase in beam current. With this arrangement overloading of the EHT source and of the normal supply stage, particularly important in the case of battery operated portable television receivers, is prevented with introducing image distortion as in known current limiting proposals. The brightness of the display is controlled by means 14 which, during normal operation biases grid 3 to a potential more negative than the potential across circuit 15, 16 so that diode 17 is non-conductive.

Title: Improvements in microwave oscillators
IPC: H03B5/18
Filed: 1966-12-30
Abstract: 1,145,654. Valve oscillating circuits. TRAK MICROWAVE CORP. 30 Dec., 1966 [4 Jan., 1966], No. 58445/66. Addition to 1,118,633. Heading H3F. The invention relates to a microwave oscillator comprising a tubular outer conductor 100 within one end of which a thermionic valve 102 is coaxially mountable with its cathode 108 electrically connected to the outer conductor 100, and its anode electrically connected to one end of an elongated anode line 132 disposed coaxially within the outer conductor. The anode line conductor includes means 134, 136 forming a first coaxial transmission line, the end of which nearer the valve is short-circuited and the other end open-circuited. A grid sleeve 156 is disposed coaxially between the outer conductor 100 and anode line 134, being electrically connected to the grid of the valve and having a free end beyond which the outer and anode line conductors co-operate to define an anodecathode cavity terminated by terminating means including an electrically conductive sleeve 126 disposed coaxially about, and in closely spaced relationship to the anode line conductor 134 so as to define a second transmission line coextensive with the first transmission line, the second transmission line being electrically connected in series with the first transmission line at the open-circuited end of the latter, to provide a double folded choke for preventing leakage of R.F. energy from the anode-cathode cavity. A radial flange 124 is fixedly mounted within the other end of the outer conductor 100, which electrically connects the conductive sleeve 126 to the outer conductor so as to terminate the anode-cathode cavity and which has a central hole through which the other end of the anode line projects for connection to an external power supply. An insulating sleeve 138 is located between the anode line 134 and conductive sleeve 126: tuning is performed by means of a tuning screw 160. The two transmission lines forming the double folded choke are each made a quarterwavelength long: the anode line is worked in the three-quarter wavelength mode. According to the invention, means are provided to improve the electrical characteristics of the feedback energy from the anode to the grid of the valve, and may take the form of a knob 162 formed on the end of the inner anode line conductor 132 to act as a lumped capacity. Alternatively the outer end of the grid sleeve may be supported from the outer conductor by means of a ring of insulating material (Fig. 8, not shown).

Title: A Method of Coating a Web for Preparing a Photographic Light-Sensitive Element
IPC: G03C1/74
Filed: 1967-12-28
Abstract: 1,190,790. Photo-sensitive laminates. FUJI SHASHIN FILM K.K. 28 Dec., 1967 [28 Dec., 1966], No. 58941/67. Heading B5N. A method of coating the opposite surfaces of a continuously travelling web 1, for preparing a photographic light-sensitive element, comprises applying photographic coating compositions to smooth continuously moving surfaces of two cooling members, e.g. surfaces 3, 3<SP>1</SP> of members 8, 8<SP>1</SP>, positioned at opposite sides of the web to provide on each of said surfaces a uniform layer or layers having the desired thickness and layer structure, cooling the layers thus formed to effect gelling, stripping the gelled layers, e.g. 4, 4<SP>1</SP>, from the cooling surfaces, and adhering the stripped layers to the opposite surfaces of the web. In one embodiment, Fig. 1, the web 1 is a film base or baryta-coated paper, and the layers 4, 4<SP>1</SP> are applied simultaneously thereto from cooling drums 8, 8<SP>1</SP>, to which they have been applied as coating compositions from hoppers 2, 2<SP>1</SP>. The web 1 may travel more quickly than the surfaces of the drums 8 and/or 8<SP>1</SP> so that the layers 4 and/or 4<SP>1</SP> are stretched and thinned down in the zones 5, 5<SP>1</SP> before application to the web. To improve adherence between the layers 4, 4<SP>1</SP> and the web 1, the layers or the web may be heated by high-frequency or infra-red heating or by hot air before the layers are joined with the web. In addition air jets are applied in the zones 5, 5<SP>1</SP> to press the layers against the web. Means may also be provided whereby the atmospheric pressure between the web 1 and the layers 4, 4<SP>1</SP> is reduced in zones 5, 5<SP>1</SP>. In a second embodiment, not shown, two layers of silver bromide solution, and a layer of aqueous gelatine solution are applied from a hopper to the surface of a cooling drum and are gelled thereon. The gelled layers are then applied to a film base travelling between the cooling drum and an auxiliary roller while stretching the layers to 1/3 of their original thickness. The coated film base then passes between a second auxiliary roller and a second cooling drum from which its uncoated surface receives an unstretched gelled layer of an aqueous gelatine solution and dye. During such passage the surface of the film base coated first is prevented from contacting the surface of the second auxiliary roller by an air cushion.
