Title: Guidance systems for mobile craft
IPC: F41G7/26
Filed: 1976-01-29
Abstract: 1524122 Missile guidance system ELLIOTT BROS (LONDON) Ltd 12 Oct 1976 [29 Jan 1976] 03581/76 Heading H4D A guidance system for a craft (e.g. a missile) comprises means for tracking a beam of electromagnetic energy in a direction to be followed by the craft and means for providing a sequence of different patterns of modulation across the beam, whereby the position of the craft within the beam may be determined by the code generated by the sequence of patterns as received by the craft due to its position, the sequence also containing a code providing the craft with beam motion data. The electromagnetic energy may be infra-red light from a xenon flash tube or a Nd YAG laser pumped thereby (Fig. 6, not shown). The modulation may be intensity modulation and the beam may be pulsed on and off at each change of modulation pattern. A beam of square cross-section may be divided into an imaginary matrix of cells 15 each allocated a 6-bit binary (Grey) code word identifying its position within the matrix, successive bits being transmitted in successive pulses, binary 1 and 0 corresponding to high and low intensity. The missile contains circuitry which receives a 6-bit code word to determine the cell in which it is located and for controlling the missile accordingly (Fig. 10, not shown). The matrices 14, together with an initial high-amplitude reference pulse, are transmitted with the aid of seven filters 16-22 (Fig. 4, not shown). In addition, two further pulseposition modulated pulses are transmitted to provide beam motion information in elevation and azimuth (Fig. 6, not shown).

Abstract: 291,832. Cooper, C. Feb. 11, 1927. Condensing and washing plant and processes. -Fuel gases are first treated with water-absorbing bodies to reduce their moisture content and then with oil in liquid state to remove naphtha. lene. The dehyration may be effected with hygroscopic liquid and carried out only to the extent necessary to facilitate removal of the naphthalene. Or a greater reduction in moisture content may be effected as by the use of solid bodies as described in Specification 268,429, [Class 34 (i), Drying gases &c.]. This step may succeed the treatment with oil. When the removal of water is carried out in a number of stages the gas is preferably first treated as described in Specification 248,841, [Class 34 (i), Drying gases &c.]. Gas from the retorts passes first through a brush washer 10 in which it is subjected to the action of hygroscopic liquid and then through a similar washer 11 in which it is brought into intimate contact with the oil. The water-absorbing material is discharged into a tank 15 from which it may be returned through a cooler 18 and it may be caused simultaneously and continuously or at intervals to travel over steam pipes 23 in order to expel absorbed water whence it passes to the tank. Oil from the washer 11 may be withdrawn continuously or at intervals through a pipe 31 for steaming to recover naphthalene. Specification 285,936, [Class 34 (i), Drying gases &c.], is referred to in the Provisional Specification.

Title: A process for the photo-mechanical manufacture of printing forms for intaglio printing with a doctor
IPC: G03F5/20
Filed: 1936-02-12
Abstract: 458,968. Photo-mechanical printing- surfaces. BEKK & KAULEN CHEMISCHE FABRIK GES., and GORIG, J., Loevenich, near Cologne, Germany. Feb. 12, 1936, Nos. 4289 and 4290. Convention dates, April 2, 1935 and Jan. 23, 1936. [Class 98 (ii)] The use of pigment paper in preparing intaglio printing-surfaces with which a doctor blade is used during printing, is avoided by applying directly to the surface of a plate or cylinder, e.g. of copper, zinc, or aluminium, a light-sensitive colloid layer, printing the image and a screen thereon in succession and etching the surface. A colloid soluble in hot water may be used or one which swells without dissolving and thereby allows the etching agent to penetrate the unhardened parts. Suitable colloids are glue (such as that known under the Registered Trade Mark " Beka "), gum, or gelatin sensitized with bichromate, and a suitable etching agent is ferric chloride to which an organic acid such as lactic, acetic, formic, or citric acid, may be added to assist penetration. A filler such as a red pigment may be added to the layer which may also be dyed to render the image visible after development. Where letterpress is to be included, this may be mounted on a glass plate with the original and copied with it. The exposure under the screen should be of sufficient duration (e.g. three times as long as that for the image) to harden the colloid completely down to the base in the exposed parts. A hardening agent such as alum or formalin may also be used. The process may be used for preparing plates for multicolour printing.

Abstract: 976,498. Packaging-machines. J. G. E. HILLMAN, and MOLINS ORGANISATION Ltd. Feb. 8, 1961 [Feb. 9, 1960], No. 4586/60. Heading B8C. A cigarette collecting apparatus, of the type in which cigarettes are first stacked and then the whole stack is transferred by pusher 3 into a tray of suitable shape, comprises members 20, movable to enter the slots in the end walls of a slotted tray 1 (Fig. 1) and having surfaces to guide the cigarettes entering the tray, and means 15-19 to move the members 20 into the slots before cigarettes begin to enter the tray. Cigarettes fed in through a chamber 40 assemble on a platform 5 in an upper position (not shown). When a sufficient number have collected, a set of needles 6 enters the chamber 40 to pierce the ends of cigarettes therein. The platform 5 is then lowered taking with it only the stack of cigarettes below the level of the needles 6. As platform 5 approaches its lowermost position a roller 12 mounted on it engages a cam surface 14 on a lever 9 pivoted at 10 and carrying a bridge member 8 which consequently moves into a position between the tray 1 and the platform 5. As the bridge 8 moves, rollers 15 mounted on it engage plates 16 mounted on bell-cranks 17, 19 pivoted at 18 and carrying plates 20, which thus move into place in the slots at either end of tray 1. A reciprocating pusher 3 then transfers the stack of cigarettes from platform 5 to the tray 1. The platform 5 returns to its initial position, the needles are withdrawn and the cycle is repeated. In a modification (Figs. 6-8, not shown) the plates 20 are mounted on arms pivoted for rotation about a vertical axis instead of a horizontal one. Specification 877,875 is referred to.
