Title: Electrically controlled fluid-actuated fluid flow control valve
IPC: F23N1/08
Filed: 1972-02-23
Abstract: 1347215 Valves SAUNIER-DUVAL 23 Feb 1972 [2 March 1971] 8367/72 Heading F2V [Also in Division G3] A gas valve for a water heater or boiler, comprises an inlet 2, an outlet 25, a diaphragm valve 8 co-operating with seating 3, and a throttle member 19. An electro-magnet 16 receives square-wave pulses and thereby causes pivoted arm 13 to alternately close orifices 9, 10 to set up in chamber 5 a mean pressure of a value dependent on the duration of the pulses. A fall in the mean pressure causes the diaphragm valve 8 to lift off its seating 3 but, initially, the member 19 remains seated and allows a small flow of gas to the outlet 25 via slots through its peripheral depending wall. Further fall in the mean pressure and consequent further lift of valve 8, causes a stop 20 to engage and lift the member 19 to provide increased gas flow. A by-pass passage 26 with adjusting screw 27 is also included.

Abstract: 794,538. Cooking rice. LEDUC, R. P. C. CARCASSONNE-; March 20, 1956 [Jan. 25, 1956], No. 8755/56. Addition to 779,576. Class 58. The continuous process for cooking rice disclosed in the parent Specification is modified in that rice, after having been soaked in water and drained on the inclined portion of an endless belt 1 and cooked in live steam as it passes through a chamber 11, is partially dried, agitated and finally dried as it passes through a chamber 35, wherein agitation and final drying occur simultaneously. Hot air at a temperature of about 90‹C. may be fed into the chamber 35 through ducts 36a, 36b and 36c and may leave through ducts 37a, 37b and 37c. The rice passing through the chamber 35 may be agitated by stirrers 38 each comprising a fixed vertical comb and a rotatable comb whose teeth alternate with and pass between those of the fixed comb. The stirrers may be constructed and arranged so that the nearer a stirrer is to the outlet of the chamber 35, the smaller is the clearance between the teeth of its fixed and rotatable combs. A transverse partition (not shown) provided with a flexible strip bearing on the rice may be arranged around the belt at the outlet end of the chamber 35, to form an enclosure into which cold air instead of hot air may be fed through the duct 36c to cool the cooked and dried rice. This, having emerged from the chamber 35 may be removed from the belt by a scraper 23. The endless belt 1 may be replaced by two belts, one carrying the rice through the soaking and draining apparatus 3, the other carrying it through the chambers 11 and 35. The apparatus 3 may then be located above the chambers 11 and 35.
Patent GB-915305-A (GB)
Title: Process for separating the components of mixtures
IPC: G01N25/14
Filed: 1959-03-13
Abstract: A process for separating the components of mixtures by fractional sublimation comprises placing a mixture in a sealed end of a tube which is supported in a furnace with said end uppermost and applying a reduced pressure to the interior of said tube whereby sublimable materials are volatilized and form as separate zones in the lower portions of said tube; the furnace having a temperature gradient which decreases from the vicinity of the sealed end of the tube toward the lower portion of said tube, and each part of said tube being maintained at a substantially constant temperature within said furnace.  The term "mixture" also embraces substances which are decomposable to give sublimable products.  Apparatus for performing the process is substantially the same as that disclosed in Specification 915,306, to which reference is made.  The location and nature of the zones resulting from the process are characteristic of the mixture separated and may therefore be used in analysis or in the case of urine, blood and other body fluids, for diagnosis of disease. The sample may be held in the testing tube by means of a spring, and liquid samples may be first incorporated into an absorbent, e.g. diatomaceous earth.  Examples of suitable temperatures which may be used for the separation of (a) urine components, (b) copper and zinc acetylacetonate and (c) caffeine in a sample of tea are provided, together with the characteristic deposition (condensation) temperature under specified conditions for cholesterol, phthalic anhydride, naphthalene, caffeine and urea. Specified temperature gradients range from upper temperatures of 70 DEG -350 DEG C. to lower temperatures of 37 DEG -70 DEG C.

Title: Improvements in shock absorbing devices
IPC: B61G11/08
Filed: 1960-03-14
Abstract: 940,067. Railway vehicle combined buff and draw gear. A. BROOM. March 14, 1960, No. 8837/60. Heading B7T. [Also in Division F2] A shock absorber is particularly described with respect to railway vehicle combined buff and draw gear mounted in a casing 6 fixed to the vehicle chassis, and comprises a buffer coupling head 7 attached to a shaft 17, and collars 11A, 11B and frusto-conical members 3, 4 which are slidably mounted on the shaft and may be abutted by either of the shoulders 17A or 18 to telescope with respect to a member 1 to compress and roll at least one resilient ring 5. The angle of taper of all the sides of the member 1 is the same, but in the male members 3, 4 the angles of taper of the rounded corners 8, 9, 10 differ, so that as the gear operates, the loading on the rings 5 is not uniform but is applied in balanced order, first to the portions of the rings adjacent sides 9, then to the portions adjacent the rounded corners 8, and finally to the portions adjacent sides 10. The rings may roll in operation and the gear may be pre-loaded. In other modifications the taper angles of the members 3, 4 may be the same whilst the angles of the bore of the member 1 may vary, or the rings may be of non-uniform cross-section. The load characteristics of the gear may be further varied by rotating the male members about their axes relative to the member 1. In the embodiment of Fig. 5 the members 12, 13, and 14 are grooved and different size rings are fitted therein, but the same effect may be obtained by varying the sizes of the grooves and using rings of the same size, or by a combination of groove and ring sizes.

Abstract: 457,303. Article-delivery apparatus. VANBERGEN, C. V., Lowfield Park, near Crawley, Sussex, and JONES, F. B., 14, Sylvan Road, Upper Norwood, London. March 26, 1936, No. 9005. [Class 18] [See also Group XVIII] Ice-cream cartons, or other packages to be dispensed, are stored in a number of shoots 6 in a receptacle 5, each shoot having an ejector 16 for discharging the lowermost package, and each ejector being operated in turn by relative rotation between the receptacle 5 and an ejector operating device. As shown, the receptacle is rotatably mounted on a bearing 20 in a fixed base 21, the ejectors being in the form of spring-loaded plungers 16 disposed in radial bores in the base 5a of the receptacle. The ejector operating device comprises a snail cam groove 23 in the upper face of the fixed base 21, round which pins 16b on the plungers 16 travel. In operation, the receptacle 5 is rotated to bring the next shoot 5 opposite a delivery opening 29 in a fixed flange 28, the pin 16b of the corresponding ejector 16 entering a radial part 23a of the snail cam groove so that the ejector moves outwardly to eject an article on to wire supports 30. At the same time, the remaining ejectors are partially retracted by co-operation between their pins 16b and the cam groove 23. The successive partial rotations of the receptacle 5 are performed by a pair of knuckle-jointed levers 27, 27a sliding on uprights 26, the lever 27 having a roller 27b co-operating with helical vanes 24 on the outer periphery of the receptacle. A drum, driven for example by an electric motor set in operation by the insertion of a coin in suitable mechanism, winds in a cable 31 which draws the levers 27, 27a up the uprights 26, the roller 27b engaging beneath a vane 24 and imparting the necessary partial rotation to the receptacle.

Title: Improvements in dish washing machines
IPC: A47L15/23
Filed: 1946-03-25
Abstract: 603,771. Dish-washing machines. HARRISON, G., NEAL, C. H., and SHELDON, S. R. March 25, 1946, No. 9092. [Class 138 (i)] A dish-washing machine has the washing and subsequent draining and rinsing operations controlled by a single sequence valve in such a manner that a predetermined amount of heated water is divided into washing and rinsing quantums which are successively circulated through rotary spray jets by a common pump. The machine, which is shown diagramatically in Fig. 12a, comprises a washing chamber 14 having a sump 26, a hot water tank 16 with immersion heater 17 and a rinsing water tank 18 receiving water from the upper part of the tank 16 and from which the water may overflow at 66 into the sump 26. The control valve comprises a rotary disc 60, Fig. 6, with a single through port 61 adapted to connect pairs of ports in the valve casing. The valve is turned by a chain gear 78 from a handle 70, Fig. 1, into six successive positions. In the " off " position, Fig. 12a, which is the position when the washing chamber is to be loaded with the articles, the port 61 connects a pipe 62 from the sump 26 with the drain 32. The sump 26 and the tank 18 are at this position, empty. In the second position, the port 61 connects a pipe 89 from a cold water supply 15 to a pipe 90 leading to the bottom of the tank 16 so that water entering this tank displaces the hot water which flows into the tank 18 and overflows therefrom into the sump 26 taking up detergent from a pocket provided in a filter fitted across the sump. This operation continues until an indicator 67 in the pipe 62 shows the sump is full. In the third position of the valve, the port 61 is blocked and an electrical contact associated with the control lever starts a pump 22 to effect the washing of the dishes. In the fourth position, the motor is stopped and the port 61 drains the sump through pipes 62a, 63a connected respectively to the pipes 62, 32. In the fifth position, the port 61 connects the tank 18 with the sump 26 by pipes 92 and 93 to fill the sump with hot rinsing water and in the sixth the motor is restarted to effect the rinsing operation. The rotating jets 28, Fig. 1, are arranged to be within the volumetric space of the dish tray 55. The water is fed to the central fixed perforated pipe 81 and passes therefrom into a box 85 of rectangular section which rotates on the pipe 81 due to the reaction of the water jets which issue from holes in a pair of opposite corners of the box. The machine is made water-tight during the washing action by a rubber gasket on the door which engages a lip on the main frame. The door is held closed by wedge-shaped levers actuated from a yoke 37 which serves both as a door handle and, as shown, as a support for the door in its open position. The articles are supported on racks on a trolley 56 which can run from rails 39 on the door on to rails 33 on the washing chamber 14. The trolley is provided with cages 59 which surround the spraying devices when the trolley is in position in the chamber 14.

Abstract: 638,912. Automatic frequency control systems. PHILCO CORPORATION. April 3, 1947, No. 9130. Convention date, April 10, 1946. [Class 38 (iv)] [Also in Group XL (c)] An automatic frequency control system for frequency-modulated oscillators, particularly in television transmitters, in which the modulation comprises two components, the second of which (e.g. the synchronizing signal) varies the carrier over a band extending beyond the first, uses a frequency-error detector comprising a first circuit having a relatively flat response over the first band and a second circuit having a sharp response and tuned just beyond the second band, the two circuits being arranged so that the error signal produced depends on the carrier frequency corresponding to the synchronizing signal peak. The Figure shows an arrangement for converting a 75 me/s. F.M. television signal to 115 mc/s. for retransmission at a relay station. An output from the 115 mc/s. amplifier 3 is applied to a discriminator 7 comprising low Q circuit 8 tuned to a carrierfrequency within the vision component range and a high Q circuit 17 inductively coupled to the first circuit, tuned just beyond the carrier frequency corresponding to the synchronizing signal peak. The two halves of the discriminator are arranged in opposition and the crossover point adjusted so that changes in carrier amplitude are balanced out but a drift of the peak synchronizing carrier frequency towards the resonant frequency of the high Q circuit carries a large change of control voltage which acts on the frequency correcting deviator 5 to readjust the local oscillator frequency.
