Title: A method of and means for regulating pressure conditions in flues or air conduits
IPC: F23L13/00
Filed: 1934-04-09
Abstract: 422,607. Fluid - actuated valves. KORNGIEBEL, G., 17, Kaiserplatz, Kassel, Germany. April 9, 1934, No. 10697. [Class 135] In a device for automatically regulating pressure conditions in a flue gas conduit of a furnace, or in an air conduit &c., a regulating damper is freely pivoted in the conduit and is loaded so that it may oscillate freely in response to changes of pressure. In one form, Figs. 1 and 2, a vertical conduit 1 is provided with an aperture 2 through which the regulator may be inserted as a unit. The closing plate 3 carries a supporting arm 4 with an extension arm 5 which supports one of the pivot pins 7 of the damper 6. The damper is slotted at 8, the lower slot carrying an adjustable weight 9 which normally maintains the damper in a vertical position with the flue fully open. Guide pins 10 locate the device in the conduit and locking handles are provided at 11. The amplitude of oscillation of the vane is indicated by a pointer 12 mounted on one of the pivot pins. When a drop of pressure occurs, the damper is first moved in one direction to an inclined position wherein the flue gas is throttled, until the restoring force of the weight 9 overcomes the displacing force whereupon the damper swings back past its open position and is then displaced in the opposite direction, a continuous pendulum movement of the damper being thus produced. In a modification, Fig. 4, the regulator may be fitted in a horizontal conduit, the damper being in this case normally held horizontal by a weight 9 mounted on a lever 15. In a further modification, Fig. 5, the regulator is fixed to a casing 16 mounted in an aperture of a chimney. In another modification, the regulator is fitted in the aperture of the roof of a horizontal conduit. In some cases the damper may be apertured to facilitate escape of the flue gases, when the damper is in the closed position. In another form the ends of the damper may be bent as shown in Fig. 10. In another modification, Fig. 11, the pivot pins 7 are mounted near one edge of the damper. In some furnaces the oscillations of the damper may be adjustably limited by means of a movable shield 21, Fig. 15, which may be positioned to limit the roll of the pivot pins 7 on their bearing surfaces.

Title: Improvements relating to helical winding machines for covering uncured rubber tubing with yarn
IPC: B29D23/00
Filed: 1950-05-01
Abstract: 668,452. Tube-making machines. PIRELLI SOC. PER AZIONI. May 1, 1950 [May 10, 1949], No. 10710/50. Class 99 (ii) Uncured rubber tubing, previously inflated to increase its firmness in the absence of a core, is unwound from a rotatable pan by a series of driven pulleys and fed 'into a lower part of the machine, Fig. 4, wherein while being subjected to a traction force equal to its own weight it follows an upward path and is covered with (a) a helically wound layer of yarn fed from a series of bobbins B carried on a rotatable platform 31 and following the course of a drift 45 fixed to the platform, (b) thin sheet rubber, which may have overlapping longitudinal edges, (c) a second layer of helically and oppositely wound yarn in a manner similar to the first. The tubing is discharged vertically from the upper part of the machine by a traction drum 19, Fig. 2, around which the tubing may be wound with a double turn, into a rotatable pan 21. The finished tubing may be vulcanized. The yarns may be unwound " off-top " from vertically mounted and non-rotatable bobbins, fed through bushes 34 in the platform-spider 33 and wound a complete turn around rubber pulleys 35 which are braked under adjustable spring pressure so that a slight constant tension is imparted to the yarns. Before being laid on the tubing the yarns may pass through feed rings 39, a guide 40 fitted with pivotally mounted and centrifugally acting feelers which swing outwardly on the breakage of a yarn and stop the machine through the agency of electrical means, and a second guide 44, follow the surface of drift 45, which may be rifled and coaxial with a fixed inner drift 47, and then pass through a slotted reed plate 46. The relative speeds of rotation of the plantforms may be altered to enable the winding pitch of the yarns to be varied: There may be two rolls of rubber strip supported' on the machine which are operated simultaneously to ensure continuity of feed of the strip, and a device comprising collars encircling the yarns operated by electromagnets when the machine is stopped to lock the yarns to the surface of drifts 45.

Title: Method and circuit for controlling the cold output of a low temperature condenser
IPC: F25B49/02
Filed: 1971-04-22
Abstract: 1332563 Automatic control of refrigeration LEYBOLD-HERAEUS-VERWALTUNG GmbH 22 April 1971 [22 April 1970] 10874/71 Heading G3R The cold output of a condenser is controlled by operating a magnetic valve in accordance with the difference between actual and desired values in such a way that the operating frequency of the valve is varied subject to a predetermined maximum frequency. As shown, an electrical signal from a gauge 1, responsive to refrigerant pressure in the condenser of a refrigerator in a freeze drying plant, is compared with a signal applied at 10, representing a desired pressure, so that any difference charges a condenser 3 to cause operation of a transistor relay 5 and hence an electro-magnetically operated valve 8 controlling the flow of refrigerant in its liquid state. Auxiliary relay contacts 7 connect a discharge resistor 9 across the condenser to produce an on/off action of valve 8 having a frequency which increases with the error and an "on" time which also increases with error so that the frequency never exceeds a predetermined value up to the point at which the valve remains open continuously until the pressure is corrected. The signals representing detected and desired pressures may be applied through a feedback differential amplifier.

Title: Waveguide to strip transmission line directional coupler
IPC: H01P5/18
Filed: 1959-04-01
Abstract: 936,456. Directional couplers. SPERRY RAND CORPORATION. April 1, 1959 [May 14, 1958], No. 11079/59. Class 40 (8). A directional coupler comprises a hollow waveguide coupled to a strip transmission line either by slots in a ground plane conductor of the strip line which co-operate with a slot in the waveguide wall, or by slots in the waveguide wall arranged adjacent a dielectric layer of the strip line, the slots being arranged at an acute angle, preferably 45 degrees, to the longitudinal axis of the waveguide and being spaced from each other a round-trip distance of 180 electrical degrees at the design frequency to provide cancellation of backward-coupled waves. It is stated that the slots are not spaced at quarter wavelength intervals as is usual because the velocities of wave propagation in the primary and secondary lines are unequal. In the construction shown in Fig. 1, slots 6, 7, 8 in the copper ground plane conductor 9 of the strip line 1 co-operate with a slot 18 in a narrow wall 5 of the waveguide 2, the copper strip conductor 11 being spaced from the ground plane conductor 9 by a dielectric layer 10 and from the copper ground plane conductor. 13 by a dielectric layer 12. If desired, the ground plane conductor 13 and the dielectric layer 12 can be omitted. The strip line 1 is connected at one end to a coaxial line 17 and at the other end to a termination 22 and brass plates 14, 15. The termination 22 absorbs any backward energy directed along the strip 11 and comprises, Fig. 5, a narrow band of evaporated metal film 21, having a resistivity matching the impedance of the strip line, centrally located on a heat-resistant electrical insulator, e.g. a ceramic or glass wafer. Two bands of solder film 23, 24 are placed on each side of the metal film and a thin coating of quartz may be provided to seal the film. The strip conductor 11 is connected to one soldered end 23, 24 of the termination 22 and the other end of the termination is clamped between the brass plates 14, 15. In the construction shown in Fig. 6 the slots 6 &c. are arranged in a narrow wall 50 of the waveguide 20 adjacent to the dielectric layer 10 of the strip line 19, the ground plane conductor 9 being omitted. As in Fig. 1 the other dielectric layer 12 and ground plane conductor 13 can be omitted. TE 10  mode propagation is referred to. The backward wave from the slot 6 can pass to an energy absorbing termination or to a coaxial line. The slots are arranged with their coupling coefficients obtained from the binomial or the Tschebychev expansion. The array of slots shown in Fig. 8 is derived from the binomial expansion and is suitable for an L-band coupler providing maximum narrow wall coupling. It is stated that all types of hollow waveguides can be used including circular waveguides. A mathematical treatment is provided. Reference has been directed by the Comptroller to Specification 820,212.

Abstract: 674,460. Dispensing sugar cane setts. HULETT, R. S. L. May 4, 1950. [May 10, 1949; April 1, 1950] No. 11089/50. Class 78 (i). A machine for dispensing individual rodlike articles from a mass of such articles, includes a hopper for a mass of articles the width of which hopper exceeds the length of the articles to be dispensed, a discharge passage extending from the hopper and communicating with the hopper through an elongated throat long and wide enough to permit a single article to pass breadth ways therethrough, a displaceable element biased to obstruct the throat, selecting means to select a succession of individual articles from the mass in the hopper and to present each in turn to the throat, isolating means to isolate each selected article in turn from this succession of selected articles, and ejecting means to displace the obstructing element and to eject the selected article through the throat. Fig. V. Sugar cane setts are fed by endless conveyer 8 to fall into hopper 11 wherein they are pushed (manually) by pusher 12 on to platform 16 down which they roll being fed forward by roll 17 and by roll 19, and slide forward past roll 23 whenever the fingers 24 thereon are retracted as said roll rotates, so that the sett is discharged past spring loaded flap 2 1 by endless rotating chains 22. The effect is that the setts are fed as a uniform stream by rolls 17 and 19 and as isolated individuals by roll 23, the fingers 24 of which project into the path of the setts and knock back or retard surplus setts. The three rolls are driven from the wheels of the carriage on which the apparatus is placed, the carriage being tugged by a tractor. Pickets 38 prevent excess setts touching chains 22 and one of the pickets 38 carries a spring secured to its lower end, the said spring engaging a sugar cane sett as it emerges and causing it tu fall in an inclined position into the furrow in the ground.

Abstract: 851,213. Engine stop gear. GODDIN, E. A. (Saunders, P. K.). March 25, 1958 [April 5, 1957], No. 11121/57. Class 122 (4). A liquid fuel injection engine, especially a diesel engine 1, is automatically stopped by shutting off the fuel supply to the engine when the level in the fuel supply tank 5 or in the lubricating oil sump 2 falls below a predetermined amount. Fuel is supplied from the tank 5 by a pipe 6 to the engine-driven fuel injection pump 7 and a float 9 on a pivoted arm 10 in the tank is connected to the pump delivery shut-off arm 15 by a link 14 and an arm 13 so that when the level in the tank falls below a certain level the engine is stopped. A branch pipe 16 extends from the pipe 6 to a needle valve 17 normally closed by a spring 27 in a chamber 22 connected by an orifice 21 with the sump 2. When the lubricating oil level in the sump 2 falls too low a float operated arm 24 moves a tappet 26 against the spring 27 to open the valve 17 and allows oil from tank 5 to drain through a pipe 18 into a tank 19. When sufficient oil has drained away the engine is stopped as described above.

April 15, 1931, No. 11212. Convention date, April 16, 1930. [Class 100 (ii).] In a process for reproducing wood graining and like natural effects on bases such as sheet metal, wall board, or the like, the base is first provided with a ground colour corresponding to the predominating colour of the original although the shade may be varied, and then two design patterns are separately printed thereon, if desired out of register, one of the patterns being arranged to emphasize the intermediate tone portions only, and the other pattern emphasizing the grain only, and being printed with a greater thickness of pigment. The printing-plates may be prepared by any of the known methods either in intaglio or relief, and the printing is preferably effected by the offset process. The first printing- plate may be prepared photographically from an artificially-prepared reproduction of the intermediate colour portions of the original, and in printing a comparatively light colour is used. The second plate is prepared to bring out the darkest tones of the grain design in sharp contrast. In a modification, the first plate is prepared by etching the intermediate and dark grain portions to nearly uniform depth by using a comparatively strong acid and etching rapidly, while the second plate is deep etched slowly with a weak acid to bring out the grain design in strong contrast. If the first plate is deeply etched a light colour is used, and the first plate may show the intermediate and dark grain portions of the original. If the first plate be etched for the intermediate colour, and the second plate be etched to bring out the dark grain portions in sharp contrast, the same colour may be employed in printing. In order to prevent the formation of slightly and uniformly offset images resulting from the non-registration of the printed designs, one of the photographic reproductions used in the preparation of one of the plates may be slightly enlarged or reduced. Specifications 169,515, [Class 100 (ii), Printing processes &c.], 369,414, and 374,206 are referred to.
