Title: Improvements in or relating to copying machines
Inventor: YANAGAWA NOBUYUKI
IPC: G03B27/24
Filed: 1967-08-15
Abstract: 1,148,087. Delivering sheets. RICOH K.K. 15 Aug., 1967, No. 37351/67. Heading B6H. [Also in Division G2] Means for separating original and photographic copy sheets after being passed round a printing cylinder and lamp, as in Fig. 1 (not shown), comprise a plate 10 integral with a disc 11, mounted for rotation on a shaft 9. The mounting means includes a clutch arrangement (Fig. 4, not shown) such that while plate 10 and disc 11 normally rotate with shaft 9, they are prevented from so doing if a restraining force is applied. Notches 10a are formed in the periphery of the plate 10, and adjacent abutments 11a in the disc 11. A bell-crank lever 16 is pivoted at 18 so that one arm 16a engages an abutment 11a of disc 11, thus preventing it from rotating, while the other arm 16b lies adjacent an opposite notch 10a. The original and copy sheets are fed through the apparatus so that they pass between rollers 8a, 8b to the separating means with the leading edge of the copy sheet 17 slightly in advance of the leading edge of the original, so that it enters notch 10a (Fig. 2a). In so doing, it engages arm 16b, pivoting lever 16 so that its other arm 16a moves clear of abutment 11a so allowing plate 10 and disc 11 to rotate. When the position of Fig. 2b is reached, the leading edge of sheet 17 meets a fixed plate 19 so that, with continued rotation of disc 10, it is pushed out of notch 10a and passes on to a plate 20, which guides it up to further conveying means which carry it on to a developing section (25, Fig. 1, not shown). Meanwhile the original passes downwards, under its own weight, on to a receiving plate 21. In the modification of Fig. 5 (not shown), the abutments and notches are formed on the same single plate (10).

A preheater for rotary kilns comprises a vertical cylindrical body, a series of receptacles with perforated bottom and walls inclined downwards and inwards, superimposed coaxially and spaced from the wall of the cylindrical body by means of brackets or the like, and a series of movable deflectors of frusto-conical shape arranged coaxially within the receptacles to form a variable passageway between the receptacles and deflectors for the material introduced at the top of the preheater, the receptacles being spaced apart so as to leave between them annular apertures for the passage of the hot gases rising from the bottom of the preheater along the walls thereof and drawn towards the centre of the preheater by the suction of a forced draught applied thereto. The preheater comprises a tubular chimney K, fixed perforated metal receptacles A superimposed coaxially and spaced from the chimney wall by brackets T and coaxial frusto-conical deflectors B which are vertically adjustable on columns F to enable the deflectors B to be moved axially toward or away from the fixed receptacles A to provide a variable passageway for controlling the thickness of a bed of material introduced through an upper hopper having synchronized closure members H, H<SP>1</SP>. Radial gates D adjustable from outside the preheater are provided in the annular passage between the chimney wall and the fixed receptacles A to control the hot gases rising from a rotary kiln P so as to cause the gases to pass through annular passages C, C 1 , C 2  formed between superimposed receptacles A and through the material passing downwardly between deflectors B and receptacles A. A movable gate E formed as a rotatable or vertically displaceable disc operable from the outside of the preheater is mounted in the central opening at the top of each deflector B to permit adjustment of the suction of the gases flowing upwardly through the preheater under the influence of a forced draught created through conduits I in an upper chamber N of the preheater. A stray disc L at the base of the preheater discharges the preheated material into a feed hopper O of the kiln P. The columns F may be replaced by a single central pipe with apertures for the free passage of the hot gases rising from the kiln.

Title: Dew point hygrometer
IPC: G01N27/12
Filed: 1966-08-22
Abstract: 1, 113, 900. Measuring dew point temperature, electrically. VAPOR CORPORATION. Aug. 22, 1966 [Dec. 17, 1965], No. 37480 / 66. Heading G1N. In a dew point hygrometer a gas is drawn by a pump over the surface of a sensor element comprising a pair of interdigitated electrodes, the electrical conductivity measured between which is a function of the water vapour content of the gas, the sensor is maintained at a temperature slightly above the dew point temperature by a thermoelectric module using the Peltier effect, and the temperature of the sensor is measured by a thermocouple and converted to give a measure of the dew point temperature. The sensor element includes a printed circuit board (Fig. 6), e.g. of glass epoxy, having a pair of conductive surfaces 54, 55 of gold coated copper printed thereon. The surface 54 has a plurality of fingers 54a interdigitated with fingers 55a of the surface 55. The sensor is fixedly mounted on a thermoelectric module (39) Fig. 5 (not shown) which is a current operated device providing a heated or cooled source. The sensor is connected in a resistance bridge the unbalance output of which operates the thermoelectric module to bring the sensor to a temperature that causes a vapour condition on the sensor surface having a predetermined conductivity or resistance, whereby the bridge circuit will be rebalanced. The temperature of the sensor which should then be about 5F. above dew point temperature is read-out by a thermocouple (59) Fig. 8 (not shown) arranged on a copper pad 58 (Fig. 6) in the centre of the sensing surface of the sensor. The bridge circuit is adjusted or compensated to correct to read-out temperature to give dew point temperature at the read-out meter (68) Fig. 11 (not shown).

Filed: 1959-11-11
Abstract: <PICT:0878884/III/1> <PICT:0878884/III/2> <PICT:0878884/III/3> In the porcelain enamelling of a metal article, the article is supported with the surface to be enamelled generally vertical, a flat stream of slurry consisting of a suspension of frit in water is applied to the upper edge of the surface in a quantity sufficient to flow across the surface whereby an alluvial coating of damp frit is deposited thereon and the frit is then fused on the surface into an imperforate layer of porcelain.  The sheets 2, which may be of corrugated steel are carried on an oblong or elongated oval conveyer 1 between pipes 3, by which they are covered by the slurry, thence through a drying oven to a fusing furnace.  The slurry in a tank 9, open upwardly, is forced through a conduit 8 by a pump 6 operated from a motor 7 and through a manifold 5 to the pipes 3 which are vertically disposed with closed tops and with vertical slits 4 adjacent the tops, the pipes 3 being telescopic so that the slits are positioned opposite the upper edges of the sheets 2 to give a flat stream which flows downwardly over the sheets 2, any excess slurry falling back into the tank 9 for recirculation.  The coating apparatus is mounted on a framework 10 on castors 11 for exact positioning relative to the path of the sheets 2.  The conveyer 1 comprises a track 12 under which each carriage 13 is slung by a pair of rods 14 with rollers 15 running on the track 12 and hooks 16 to engage in openings 17 in a hanger bar 18.  A yoke 19, pivotally supported at the centre of bar 18, has lateral arms 191 for supporting beams 20 each of which has a pair of pivoted wires 21 with hooked ends for engagement with holes 22 in the upper margins of the sheets 2.

Title: Improved mechanical relay
IPC: H01H51/08
Filed: 1929-12-13
Abstract: 344,929. Escapement mechanism. CREED & CO., Ltd. and SALMON, R. D., Telegraph Works, Croydon. Dec. 13, 1929, No. 38229. [Class 80 (iv).] Mechanical relays for telegraphic &c. apparatus comprise a controlling member such as the relay armature which is movable alternately between two positions, a continuously driven rotatable driving member and a driven member controlled by the controlling member and driven from the driving member through frictional bearing surfaces and an eccentric or the like for actuating relayed movements which is disposed on the driven member relatively to the frictional bearing surfaces on the driving and driven surfaces so that the thrust resulting from the actuation of the relayed movements increases the driving contact between the driving and driven members. As shown in Figs. 1 and 2, the controlling member 1 is formed with teeth 5, 6 one of which normally engages a tooth 4 on the periphery of a driven member 3 which is formed with a plain cylindrical bearing surface within a continuously driven driving member 2. An eccentric pin 7 is mounted on the member 3 and is connected by a link 5 to a pivoted arm 9 bearing a blade spring 11, such as a contact spring, which works between stops or contacts 13, 14. At each oscillation of the controlling member the tooth 4 is released and the member 3 driven through a half revolution. The blade spring 11 as shown is flexed as it approaches its extreme positions and the ratio of the radius of the cylindrical bearing surfaces between members 2, 3 to the radius of the eccentric pin is made so that the thrust resulting from the flexing of the blade spring 11 increases the frictional driving contact between members 2, 3. The theoretical considerations enabling this to be effected are set forth in the Specification in which it is deduced that a bearing surface radius not less than five times the radius .of the eccentric pin is essential to fulfil this condition. In order to ensure that the blade spring is carried across its mid position in which it exerts no reactional thrust on the bearing surfaces an auxiliary spring 16, Fig. 4, secured to the driving member 2, bears on a small pad 15 carried in a slot 17, Fig. 3, in the wall of the driving member so pressing it into frictional contact with the driven member 3.

Title: Oxidation of propylene
IPC: C07D301/06
Filed: 1959-11-12
Abstract: A catalyst for use in the oxidation of propylene to propylene oxide consists of a mixture of a compound of cobalt, copper, manganese, vanadium or chromium which is soluble in formic acid and acetic acid and a compound of barium or lead which is also soluble in formic acid and acetic acid.  Examples are given of the use of mixtures of (a) cobalt acetate and lead carbonate; (b) cobalt acetate and barium carbonate; and (c) manganese acetate and barium acetate as catalysts.ALSO:Propylene is oxidised to propylene oxide in the liquid phase in an inert organic solvent with an oxygen containing gas at elevated temperature and pressure in the presence of a catalyst consisting of a compound of cobalt, copper, manganese, vanadium or chromium which is soluble in formic acid and acetic acid in admixture with a compound of barium or lead which is also soluble in formic acid and acetic acid, and which acts as promoter.  The oxygen-containing gas may be air, oxygen-enriched air or oxygen-depleted air.  Suitable inert solvents are, for example, cyclohexane, hexane or heptane.  If desired, propylene-propane mixtures may be used as starting materials.  If a mixture of ethylene oxide and propylene oxide is required an ethylene-propylene mixture, which may also contain saturated hydrocarbons may be used as starting material.  In addition to the propylene oxide, propylene glycol, acetic acid and formic acid are formed.

Abstract: 1,137,967. Web printing machines. FRITZ BUSER A.G. 26 Aug., 1966 [16 Sept., 1965], No. 38474/66. Addition to 1,037,467. Heading B6C. A web printing machine, see Fig. 1, comprises an endless conveyer 2 trained around two rollers 3 and 4 at opposite ends of the machine, means being provided to drive the upper flight of the conveyer 2a intermittently across a printing table 1, and to drive the lower flight 2b continuously through a masking installation 5 and a glue applicator 6; the rollers move in unison towards positions 3<SP>1</SP> and 4<SP>1</SP> when the upper flight 2a is in motion and return to original positions 3 and 4 when the upper flight is stationary, i.e. during printing, at least the roller 3 being displaceable above the plane of the table 1. The upper flight 2a is driven by means similar to that described in Specification 1,037,467, that is hydraulic or magnetic tongs 10 connected to a piston 8 in a cylinder 7 containing oil under pressure; the lower flight 2b is driven by roller 34 which is connected to electric motor 36 via an infinitely variable gear. In order to keep the conveyer belt under tension throughout displacement of rollers 3 and 4, the latter are connected together by a chain 19 which passes over deflection rollers 20, 21 and 22. The web is fed on to the conveyer from the web roll 25 by means of e supply roller 26 which may be heated; the supply roller 26 bears up against a deflecting roller 24 through the thickness of the conveyer, while the speed at which the conveyer is moving governs the amount of pressure applied by the supply roller for adhesion of the web to the conveyer, the governor being a pivoted lever 29 controlled by an hydraulic piston 33 connected to a pump 30 which is in turn controlled by the roller 24. Fig. 2 illustrates the means by which the infinitely variable gear of the motor 36 is controlled by the actual motion of the rollers 3 and 4. A chain 37 is connected to the chain 19 by end-pieces 38, and passes over a wheel 39; coaxial with the first wheel 39 is a second or control wheel 43 which controls the gearing of motor 36 via chain 40. Both wheels are provided with pins and corresponding stops so that movement of chain 37 rotates wheel 39 and causes suitable movement of wheel 43 controlling the gearing of motor 36 and hence of the lower flight of the conveyer 2b (Figs. 3 to 6, not shown).
