Title: Applying and Reading Coded Information
Inventor: HARDISTY PHILIP RICHARD
IPC: B07C3/14
Filed: 1966-04-29
Abstract: 1,161,392. Endless conveyers. M. E. L. EQUIPMENT CO. Ltd. 27 April, 1967 [29 April, 1966], No. 18866/66. Heading B8A. [Also in Division G1] Coded information in respect of an object present at or passing a predetermined location is applied to a surface by irradiating a radiation sensitive surface of the type capable of emitting radiation when subsequently irradiated and is read off during such an emission period. A pattern of ultra-violet light may be applied to a phosphor such as zinc sulphide, copper and lead and the information is released to a photocell when subsequently excited by infra-red. The phosphor may be applied to the object or to a store moving past an infra-red source, for example, to a conveyer belt, to an auxiliary belt, or to the periphery of a rotating disc, to control for example, the discharge of the objects from a conveyer. The stored information is erased by subsequent exposure to another strong infra-red source. The reading arrangement comprises an infra-red source adjacent to and preceding a photo-cell from which it is screened. There may be successive reading stages seeking pattern coincidence to operate an appropriate discharge device.

Abstract: 737,668. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1952 [Sept. 5, 1951], No. 19518/52. Addition to 730,548. Class 39 (1). In a voltage indicator having a bowl - shaped anode coated internally with fluorescent material, a rod-like cathode extending at right angles to the plane of the rim of the anode, and a deflecting electrode whose potential determines the magnitude of the shadow angle, the envelope being elongated and the longitudinal axis of the cathode making an angle α equal to or greater than 30 degrees with the longitudinal axis of the envelope, as claimed in Claim 1 of the parent Specification, the anode has a plane of symmetry 8, Fig. 1, passing through the longitudinal axis of the envelope and the axis of the cathode 1 and of the de. flector 6 lie in a plane 7 inclined at an angle of less than 90 degrees to the plane 8. In the form shown the device has grid 2, counter electrodes 3 and 4 as described in Specification 700,192, ring electrode 5 at anode potential and a fluorescent anode. The left-hand shadow edge which is the only one used for observation can move through an angle # which is about 60 degrees so that a very large path length around the anode is obtained (from 9 to 10). Alternatively α may be greater than 30 degrees and # may be increased to 90 degrees or more. A cap may be arranged over the cathode to cover the part of the fluorescent pattern not being used, Fig. 2 (not shown). A small part of the path traversed by the right-hand shadow edge-adjacent point 10-is left visible to increase the reading sensitivity at very small shadow angles. Planes 7, 8 preferably intersect at the virtual starting line of the electron fan, which is near the deflecting electrode 6 but on the cathode side thereof. The luminescent pattern is viewed through the side of the envelope instead of through the end as in the prior art and the large path length around the anode provides high sensitivity.

Patent GB-196632-A (GB)
Abstract: 196,632. Zuberbuhler, A. Feb. 3, 1923, [Convention date]. Closed-solid-fuel stoves; air supply for combustion; dampers; grates.-In a stove in which the air for combustion is preheated in a jacket more or less surrounding the combustion chamber, the air is caused to travel a considerable distance in the jacket before reaching the slow combustion chamber and is introduced approximately uniformly around the periphery of the top of this chamber; in addition to forming a secondary air supply for consuming the distilled gases it serves also for the combustion cf ignition fuel, which is arranged above the slow combustion chamber in starting the fire. The stove shown in Fig. 1 comprises a combustion chamber 3 above which is a chamber 2 forming a secondary combustion chamber for the gases and also serving to contain the ignition fuel when starting the fire. An air-jacket 13 surrounds the combustion chamber 3, and may also extend upwardly around the chamber 2, the preheated air passing to the combustion space through a space 4 between the chambers 2, 3. The fuel support at the bottom of the chamber 3 comprises a movable grate 10 above which may be arranged a fixed grate 11, in an extension of which are formed ports 12 through which air passes to the jacket 13 from the ash-pit 14; the movable grate 10 acts as a regulating damper for these ports. The exit opening 8 for the gases from the chamber 2 is comparatively small in order to delay the gases in the chamber. After the first charge in the chamber 3 has been ignited at the top by ignition fuel in the chamber 2 combustion proceeds downwardly. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the modified form shown in Fig. 2 (Cancelled), which is provided with a hit-and-miss ring damper 18, 20 controlling the air supply to the space between the chambers 2, 3, with air-supply openings 24 in the lining 6 of the chamber 3, and with a cylindrical perforated air-supply member 25 resting on the grate 11. Two other modifications, now forming the subject-matter of Specification 219,271, are also comprised. These are adapted for continuous, operation, one being provided with means for reversing the direction of the draught through the combustion chamber 3 after the first charge has been consumed, whilst the other is provided with a cylindrical combustion chamber rotatable about a horizontal axis in order that it may be reversed after each charge to bring the glowing residue of the previous charge to the top of the fresh fuel. This subject-matter does not appear in the Specification as accepted.
