Title: Improvements in Control Units for Selecting Alternative Operation Positions, such as for Frequency Selection on Communication Equipment
Inventor: SMITH SAMUEL HAROLD
IPC: H03J5/32
Filed: 1967-10-09
Abstract: 1,173,188. Key interlocks. S. H. SMITH. 9 Oct., 1967, No. 46045/67. Heading B6F. [Also in Divisions E2, H1 and H3] A control unit comprises a number of devices each of which can be locked in an operative position when operated, means being provided whereby if more than one device is operated simultaneously only one will be retained in its operative position. The invention is described in connection with a push-button unit for selecting crystals for tuning airborne communication equipment to a predetermined frequency (see Division H3), the button assembly having buttons smaller than the operator's finger. It is arranged that only the uppermost button is locked in although several are passed simultaneously. General construction. -The buttons are arranged in two pairs of vertical rows (Fig. 1, not shown) one pair bringing in a whole number of megacycles and the other pair a fraction of megacycles. The buttons 118-134 (Fig. 2) are of transparent plastic and are mounted on a panel 27 with an outer edge-lighted panel 28 also of transparent plastic. A lamp 13 illuminates the buttons from inside. Each button is attached to a slide, e.g. 118S in Fig. 3, the rear end of which actuates switch contacts Wa-Wj as described below. The slides of the buttons of two adjacent vertical rows, e.g. 118-121 are interleaved in a single vertical stack. Locking mechanism (Fig. 3).-Each button slide has a slotted plate 33 immediately above it, the slot CS co-operating with a pin, e.g. 118P, on a latch member,.e.g. 118L pivoted to the button slide at 41. When a button is pressed, the pin P moves along the slot of the plate 33 above it until it reaches the portion 40 of the slot when the latch member L is pivoted to lift a latch bar 45 which is common to all the buttons. This releases the previously pressed button. Further movement of the button causes the pin P to travel along the narrow portion 34 of the slot whereupon a notch 42 engages the latch bar 45 by a spring 51 and holds the button in. During the last part of the movement of the slide the plate 33 is moved slightly to the left, drawing the next button e.g. 119 slightly inwards. The surface 40 on the plate associated with slide 119 then causes the pin of the next button 120P to disengage from the latch bar 45 preventing this button from being latched in. Button 119 cannot latch in since its pin 119P cannot enter the narrow portion 34 of the slot 118CS. Thus even if buttons 118, 119 and 120 are pressed simultaneously only 118 will operate. If the buttons are in more than two vertical rows the corresponding latch bars 45 are linked together (201 in Fig. 12, not shown). Engagement of the pin P with the edge of the slot CS is facilitated by pivoting of the latch member L due to friction with the preceding slide. This is aided by a yieldable friction member (158 in Figs. 16, 17, not shown) around the pin P.

Abstract: 1,195,837. Photographic direct positive images. GEVAERT-AGFA N.V. Oct.6, 1967 [Oct. 24, 1966], No. 47631/66. Heading G2C. A photographic direct positive image is produced by exposing a light-sensitive material having an internal-latent-image silver halide emulsion and developing with an energetic surface developer in the presence of a substance or substances which liberate iodide ions and/or bromide ions in aqueous media and in the presence of hydrazine or a hydrazine salt, the hydrazine or salt thereof being present in the developer and/or in a processing liquid with which the lightsensitive material may be wetted before development. The substances liberating iodide and/or bromide ions may be present in the developer or in the emulsion or another layer of the lightsensitive material and may be incorporated therein by inhibition before or after the exposure step. The substances include molecular iodine and addition products thereof, organic quaternary ammonium, phosphonium, sulphonium and iodonium iodides and chloroiodates, inorganic watersoluble iodides and bromides and monobromoacetic acid. The surface developer is a silver halide developer containing no effective amount of a silver halide solvent and is energetic by reason of its high pH, elevated temperature, high concentration, the absence of restrainers such as potassium bromide and/or the presence of activators such as cyclohexylamine, phenylhydrazine or polyethylene glycols or derivatives thereof. The developing agent may be partially or completely incorporated into the light-sensitive material and the developer may therefore comprise an alkaline aqueous activating solution free from developing agent. Developing agents mentioned are hydroquinone mixtures with metal or 1-phenyl-3-pyrazolidinone but a colour developer may be used in the presence of a colour coupler to give, after silver bleaching, a positive colour image, and the process may be used in multicolour materials. Development may be conducted while overall exposing the material to light. The internal latent image emulsion is not or only slightly chemically ripened. An anti-foggant may be present in the light-sensitive material, possibly in more than anti-foggant amounts.

Title: Pigment production
Inventor: EVANS ARTHUR WALLACE
IPC: C01B13/26
Filed: 1963-12-09
Abstract: Finely divided metal oxides are prepared by introducing into a fluidized bed of particulate material at a temperature of at least 700 DEG  C. a first metal halide (not F) and an oxygenating gas and simultaneously introducing at a point higher in the bed a second metal halide.  Metals specified are titanium aluminium zirconium. Halide specified:-chloride.  Oxygenating gas specified:-air or O2. Particulate size specified:-50-2000 m .  The second halide is introduced at a distance above the first so that the first is oxidized before contact with second. The first halide may be a mixture of those specified or may be the same as the second and preferably forms sub-pigmentary particles of oxide.  When the first and second halides are the same the amount introduced as the first halide is in the range 5-90% of the whole halide introduced.  When they are different the first is in the range 0.5-10% of the total weight of metal oxide produced.  The oxygenating gas may be introduced at any point in the bed or mixed with the first metal halide. The second metal halide is added so that it mixes rapidly and uniformly with the products of the first reaction.  To the reactants may be added an alkali metal halide (potassium specified), water or silicon halide in the range 0.001-5% of the total weight of metal oxide produced.  In an example a bed of particulate TiO2 was heated to 1050 DEG  C. and TiCl4, preheated to 200 DEG  C. and containing SiCl4 in an amount to give 0.125% silica by weight of the TiO2 produced, was passed in as a first halide.  Oxygen preheated to 150 DEG  C. and containing AlCl3 to give 0.62% alumina by weight of the TiO2 produced was passed in at the same level.  Above these inlets is introduced preheated TiCl4.  Good yields of TiO2 in a finely divided state are produced.
