Title: Improvements in or relating to the treatment of products and materials
IPC: B65G15/10
Filed: 1956-05-04
Abstract: 866,208. Endless conveyers. TEMPLETON, R. A. S. May 3, 1957 [May 4, 1956], No. 13814/56. Class 78 (1). [Also in Group XIII] Sliced or whole vegetables, fruit or other material is conveyed through a treating chamber by an endless conveyer consisting of a number of narrow-spaced parallel endless strands 4 running over grooved rollers 1, 2, &c., there being provided means for disturbing the material during conveyance. The treating chamber includes a feed hopper 6, a discharge hopper 7 and means for introducing a treating medium, e.g. hot water or steam for cooking or blanching, or air for drying or cooling. The strands 4 are of wire, preferably helically coiled wire. They may also comprise heating wire for controlling the temperature within the chamber. The strands 4 may carry the articles only on the upper run (Fig. 1, not shown), or as shown in Fig. 3 may be adapted to carry the articles on both runs. This is effected by separating half of the strands from the remainder after passing a roller 9 to traverse a run 10 which rejoins the other half of the strands at a roller 11. The resultant wider spacing of the strands in this region allows the articles to pass through the strands to the lower run. An alternative arrangement wherein the separated strands pass under a roller 18 and rejoin the other half of the strands at the roller 2 is shown in Fig. 4. A similar separation of half the strands at the end of the lower run allows discharge of the articles to the hopper 7. The material is disturbed at one or more points during transit on the conveyer by a roller, Fig. 5, provided with deep grooves 3 in which the strands are located, so that annular portions of this roller project above the strands to engage the articles.

Title: Improvements in or relating to railway classification systems
Inventor: AUER JOHN HENRY
IPC: B61K7/12
Filed: 1957-05-01
Abstract: 811,821. Railway classification systems. GENERAL RAILWAY SIGNAL CO. May 1, 1957, No. 13877/57. Class 103 (1). Control apparatus for a railway classification system comprises means, such as a radar type scanner, adapted to provide a beat-frequency output signal on the Doppler principle, the frequency being proportional to the speed of the car rolling over a track section, such section being provided with at least one car retarder, and retarder control means operable under the joint control of said speed measuring means and of release speed computing circuit means providing a continuously variable output proportional for each car to the desired release speed of such car from the retarder. The amplitude of beat frequency output signal is made proportional to the proximity of an approaching car and includes circuit means operable for a predetermined period in response to a predetermined amplitude of signal output from the speed measuring means. The circuit means includes an amplifier comprising tubes 47 and 52, Fig. 3A, which are interconnected to form what is commonly known as a Schmitt amplifier circuit. This applies output signals to operate a relay when the amplitude of such signals exceeds a predetermined level. A gate circuit comprising a triode 71 passes the output signals received from the speed-measuring means to a pulse-forming circuit including the one-shot multi-vibrator 81. This generates a pulse for each cycle of beat frequency oscillation received, and the positive going of these pulses are inverted by the amplifier 85 with the result that the input to diode 86 included in the speed relay control circuit 87 comprises negative-going pulses. The speed relay control circuit 87 thus receives negative-going voltage pulses from amplifiers 85, all the pulses being of the same amplitude and width, but their frequency varying with car speed. An anticipation relay control circuit operated in a similar manner to the speed relay control circuit but the control voltage applied to the cathode of diode 111, i.e. of a somewhat higher value than that to diode 86 so that the relay A1 drops at a slightly higher car speed than the relay S1, causing the retarder to be partially released. The exit relay control circuit, i.e. operated as a function of the proximity of the car to the transmitting antenna, and is independent of actual car speed.

Title: Apparatus for stringing tennis and other rackets
IPC: A63B51/14
Filed: 1931-05-13
Abstract: 375,494. Tennis &c. rackets. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H. and BRENTNALL, G. C., of Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. May 13, 1931, No. 14122. [Class 132 (ii).] In apparatus for stringing tennis and like rackets in which the string tension is applied by a mechanical load, means are provided for positively locking the tensioning means from applying further load to a string when the tension of the latter has reached a predetermined value. The invention is described with reference to Specification 341,630. A racket 40, Fig. 1, is secured by cam operated clamps 6 and handle clamps 11, Fig. 2, to a platform 5 rotatably adjustable on a bedplate 1 to which it may be clamped by a lever 15. A lateral string 39 is secured at one end to the racket, threaded therethrough, and the free end passed over a roller 41 rotatably mounted in a frame member, and wound round one or more pegs 25 on the tensioning drum 18 freely mounted on a shaft 26, Fig. 4. A tubular shaft 32 carrying a pendulous weight 34 is connected through differential gearing contained in a rotatable casing 19 to the shaft 26. The casing 19 is rotated through worm gearing 36 by a handle 38, to rotate the tensioning drum 18 through a clutch 21 which normally connects the shaft 26 thereto. When the string tension reaches a predetermined value the pendulous weight 34 rises and ultimately a prong 45 on the arm 33 carrying the weight 34 rotates a pawl 43 pivoted at 44 into engagement with a toothed wheel 46 on the worm shaft 37 stopping further rotation of the casing 19, the handle 38 being frictionally connected to the shaft 37 to prevent shock on the stopping thereof. The free string end is now clamped at 14 as described in Specification 341,630 and released from the tensioning drum 18, the latter being declutched from the shaft 26 for this purpose by operating a lever 30 pivoted at 31 to depress the clutch operating member 29. The platform 5 may now be rotated to a new position for similarly threading the next string. To facilitate fixing the free string end to the tensioning drum 18 the latter may comprise a ring 72 screwed on to a part 73, Fig. 4. The string end after being wound round a peg 25 is passed and gripped between a shoulder 74 on member 73 and member 72 when the casing 19 is first rotated. A known device 13 may be provided to depress alternate longitudinal strings during lateral stringing. In a modification the free end of the string 51, Fig. 5, passes under a roller 54 carried by a link 55 pivoted to a weighted lever 56 pivoted at 57, and is -tensioned by operating a handle 38 which drives the tensioning drum 59 through worm gearing. As the desired tension is approached the roller 54 is lifted, until a pin 67 on link 55 lifts a pawl 64 pivoted at 63 and normally resting on a stop 65, into engagement with a toothed wheel 66 on the drum shaft stopping rotation thereof. The string tension may be varied by means of a screw 69 adapted to move the weight 58 along the lever 56 as indicated by a pointer 71.

Filed: 1941-11-04
Abstract: 552,064. Reinforced concrete floors, ceilings and roofs. PENNINGTON, A. M. Nov. 4, 1941, No. 14209. [Classes 20 (iv) and 87 (i)] A lidless five-sided box 12, Fig. 2, of concrete or clay, which may have a strengthening partition 17, is placed open side downward on a layer of concrete 18 in a mould, end to end with similar boxes. Transverse reinforcement 21 and longitudinal reinforcement 22 are provided, and the mould filled with concrete 23 so that a continuous covering of concrete unites all the boxes. The boxes may be spaced from one another longitudinally, Fig. 6 (not shown), the spaces being filled with concrete. Reinforced cavity beams thus formed may be arranged side by side, Fig. 8, with concrete grouting between them, which may extend over the tops, to form floors or other components, which may be pre-fabricated. Similar floors may be constructed in situ by placing a layer of concrete on temporary shuttering to form a soffit, placing lidless boxes on the concrete in rows separated by channels which cross at right angles, or are unidirectional only, placing reinforcement in the channels, and filling them with concrete. The soffit may alternatively be of plaster or fibreboard.

Title: The manufacture of new fluorine compounds
IPC: C08C19/14
Filed: 1935-05-15
Abstract: Rubber and rubber-like bodies such as isoprene and butadiene polymers, and white or brown factis are treated with fluorine under such mild conditions that chemical combination occurs without combustion.  The reaction may be effected or commenced in the presence of an indifferent substance or at a low temperature, e.g. below 0 DEG  C.  The fluorine may be diluted with, e.g. air, nitrogen or CO2, in proportions of 1--10 by volume per 1 volume of fluorine. Alternatively, the rubber is dissolved in, e.g. CCl4 and fluorine, which may be diluted, introduced. The products are used for rendering fluid-tight and insulating electrolytic cells for the production of fluorine.  Alternatively, the desired parts of the cell may be provided with untreated rubber and the cell operated when the fluorine produced, which is diluted with the air present, reacts. When the electrolyte is molten potassium bifluoride, the fluorinated rubber stopper insulating the anode is water-cooled since a temperature of about 250 DEG  C. is used.  With polyfluorides, cooling is required only if the temperature is above the decomposition point of rubber.  In the type of cell wherein the sides and bottom serve as cathode, passage of hydrogen evolved at the bottom through the diaphragm into the anode chamber is prevented by coating the bottom with fluorinated rubber.  Rubber plates obtained by vulcanizing soft or hard rubber mixtures upon parts of the cell and treating with dilute fluorine can be used.  Using fluorinated rubber packings and covers, apparatus used for electrolysis of water such as uni- or bi-polar cells or filter press apparatus can be used for the production of fluorine.  Specification 21557/00, [Class 41], is referred to.ALSO:Rubber and rubber-like bodies are treated with fluorine under such mild conditions that chemical combination occurs without combustion.

Patent GB-612151-A (GB)
Title: Improvements relating to phosphate coating processes
IPC: C23C22/12
Filed: 1946-05-11
Abstract: A process for producing a zinc phosphate coating on a metallic surface in which the metallic surface is brought into contact with a solution of zinc primary phosphate at not exceeding 45 DEG C., which solution contains no copper compound and is in equilibrium with zinc tertiary phosphate, i.e., the solution is incapable of dissolving any more tertiary phosphate at the temperature of operation.  When the metal surface is zinc, a modified solution is employed, viz., of a primary phosphate other than zinc, e.g. manganese which dissociates to give a solution having not more free phosphoric acid than a solution of zinc primary phosphate of equimolecular strength and at the same temperature.  After application the solution may be allowed to dry.  The solution may contain one or more oxidizing accelerators and may be treated continuously or intermittently to maintain equilibrium. Equilibrium may be produced or maintained by bringing the solution into intimate contact with the tertiary phosphate of the metal whose primary phosphate it contains.  The tertiary phosphate may be in a sludge which has separated from the said solution.  In addition to zinc primary phosphate the solution may contain up to two molecular equivalents of another mineral acid salt or salts of zinc per molecular equivalent of zinc primary phosphate. Specification 386,739, [Group II] is referred to.
