Title: Improved method and apparatus for the saturation of sugarjuices in the manufacture of beet-root and cane sugar
IPC: C13B20/00
Filed: 1927-12-15
Abstract: 283,202. Blanke, F. Jan. 8, 1927, [Convention date]. Purifying saccharine liquids.-The automatic saturation of sugar juice by carbon dioxide or sulphur dioxide is effected by causing the juice to flow from a tank in which its level is restored into an ascending pipe under pressure of the gas, the pipe being provided with overflows connected to an electric measuring instrument which operates to control admission of air to the gas flow until, at the required alkalinity of the juice measured in terms of its electrical conductivity, the air admission is suspended. As shown, the juice flows from a separator a into a tank b provided with a float h and valve i. From the tank b it is forced under gas pressure from the pipe d up the ascending pipe c which is provided with overflows e, e<1> emptying into a reservoir g. As the alkalinity in the pipe c varies, the measuring instrument operates a regulator m which dilutes the acid gas by admission of air into the gas flow from the valve n. The flow from the tank b is controlled by the level of juice in the reservoir g through the interconnected float k and valve i. The flow of gas from the pipe d is also controlled by the level of the juice in the tank b.

Abstract: 1,121,322. " White noise " generator. NATIONAL RESEARCH DEVELOPMENT CORP. 20 Aug., 1965 [20 Aug., 1964], No. 34029/64. Heading G5J. In a siren a flow of compressed gas is modulated to produce a non-uniform sequence of pneumatic pulses, spaced, and with length selected, according to a mathematical code such that the output comprises a large number of harmonics of the fundamental recurrence frequency of the non-uniform sequence. The sound resulting has an energy level that is approximately the same over a wide range of frequencies, and may be employed to simulate the noise of jet engines. Modulation of the gas stream may be by irregularly placed slots or holes in a moving tape, preferably endless, or in a drum, disc or annulus, the slots being punched according to, for example, a linear recurring sequence code. Alternatively the emission of pulses may be controlled by a pneumatic jet amplifier, responding to a planned code stored in the form of a perforated tape or generated by a pneumatic shift register, or a valve controlled by an electronic shift register may be employed to pulse the gas stream.

Title: Thermostatic control
Inventor: EDDISON WILLIAM BARTON
IPC: G05D23/275
Filed: 1946-11-19
Abstract: 637,582. Automatic temperature control systems. LORD & BURNHAM CO. Nov. 19, 1946, No. 34277. [Class 38 (iv)] [Also in Group XXXVII] A thermostatic control for greenhouse ventilators comprises a temperatureresponsive element 30, Fig. 7, controlling a switch arm 61, Fig. 5, adapted to close either of two switches 68, 69, a knob 36, Fig. 8, for setting the temperature to be maintained constant, and a handle 75 preset to impose an overriding limit to the degree of opening of the ventilators, and also manually fixing the maintained degree of opening of the ventilators when the knob is turned to a position rendering the thermostatic control inoperative. A follow-up arm 43 connected between the ventilators and a nut 39 fixedly mounted on a threaded shaft 38 of the device serves to restore the switches to neutral after the set temperature is reached. The shaft 38 carries and rotates the entire thermal unit about a lower pivot 45 and by its axial movement relative to the knob 36 counteracts the effect upon a spring 34 connected between the nut 39 and thermal element of the action' of the bellows 30. The spring 34 is initially set under compression, the control temperature being reached when the compression due to the spring and bellows is balanced by the spring 71. The switch arm 61 is mounted on leaf spring supports 64 so that its control movement is multiplied by the bellows linkage 57 and carries magnets 66, 67 operating the switches 68, 69, which respectively operate through a relay a reversing motor to open and close the ventilators. The knob 36 is mounted between an internally-threaded socket 76 and the externally-threaded shaft 38 on which the nut 39 is secured, the threads being of differential pitch. The socket 76 is releasable and independently adjustable to calibrate the device. A cam 41 on the handle 75 sets an over-riding limit to the extent of opening of the ventilators. The cam 41 operates by engaging a pin 40 on the nut 39 of the follow-up arm 43, which pin engages a spring-biassed yoke 42, Fig. 5, which by abutting a set-screw 72 on the switch arm 61 actuates the latter into a neutral position and cuts out the ventilator opening switch 68. In manual position M, Fig. 2 (not shown), of the knob, the spring 34 is extended under such tension that the switch arm 61 is biassed toward the ventilator opening switch 68 and the cam 41 then exercises control in such a way that'the pin 40 is always on the inclined surface of the cam 41. The position of the ventilators is then determined manually by the handle 75. A mercury switch interrupts the ventilator closing circuit to prevent jamming if the driving motor is not cut off when the ventilators are fully closed.

Title: Impulse receiving and registering device for automatic telephone exchanges
IPC: H04Q3/00
Filed: 1945-12-20
Abstract: 634,985. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 20, 1945, No. 34619. Convention date, Jan. 9. [Class 40 (iv)] In an automatic exchange in which signals composed of at least two kinds of electrical impulses are received by separating impulse receiving devices which cause them to be registered on the operating bars in a cross-bar switch, the selecting magnets of the latter are actuated by any one of a number of circuits, each of which can be closed by one only of the impulse receiving devices and includes a group of contacts in the cross-bar switch individual to the particular impulse receiver. In the example shown, impulses of two kinds over wires b and a respectively operate relays R1 and R2. R1 is followed by R3 which locks up and operates R6 and selecting magnet STM1. At the end of an impulse R1 is released, and R5 releases R3, holds STM1 and excites operating magnet BM0. This last operates two contact groups K1 and K2 and locks up. Release of R5 then excites R7. As R6 is slow releasing, if another impulse follows over wire b, R1 and R3 again act, breaking circuit for STM1 and exciting STM2 over the K1 contact which is the group individual to R1. A train of R1 impulses will then actuate magnets STM1 ... 10 in succession until the end of the impulse train. R6 then releases and excites BM1 which locks up and registers the selecting magnet which has operated on its bar. R7 releases later and excites R8. At the end of the next impulse train, as R8 is up, release of R6 operates magnet BM2 to register the next digit on the bar of this magnet and release R8, thereby preparing the operation of BM3. Magnets BM1 ... BMn are thus operated in turn, R8 acting once for every two of these operations. If impulses come over wire a, R2 and R4 act instead of R1 and R3. R5 ... R8 and BM0 operate as before, but the first selection magnet that can be excited in this case is STM3 and the K2 groups of contacts are effective so that SM6 follows SM1, SM8 follows SM2 and SM9 follows SM3. Thus, if each kind of impulse is called R1 and R2 the apparatus operates according to the code shown in Fig. 2.

[Class 51(ii)] Apparatus for cooling heat-treated materials e.g., coke, cement clinker, burnt lime and particularly sinter discharged from sintering machines, comprises a rotating bin structure having a downwardly and outwardly inclined surface 21 over which the sinter moves to a horizontal annular shelf 22, a vertically adjustable circular retaining wall 25 regulating the passage to the shelf 22. The rotating structure consists of vertical I-beams 5, floor beams 6 and inclined beams 7 joining the beams 5 and 6. A deck 8 of steel plate is secured to the beams 7 and extends downwardly from an inner retaining steel wall 9. A circular angle strip 10 retains refractory bricks 21 which are laid upon the deck 8, and is concentic with another strip 11, the space between the strips being filled with cast-iron grate bars 12 the ends of which seat on the strips 10, 11. The horizontal shelf comprises a steel plate 15 carried by the beams 6 and having a covering of refractory bricks 22 arranged between the strip 11 and a retaining strip 16. Flanged wheels 17 on the beams 6 run on rails 27 mounted on a foundation 28 with a channel 30 which receives cooling water and smalls passing through the grate bars 12, rotation of the structure being effected by a motor 31, through reduction gearing and a rack 19. The sinter is discharged from the sintering machine through the shoot 32 which is directed in the direction of rotation of the cooler to minimise the tumbling of the sinter blocks upon the surface 21 and the consequent production of fines therefrom. The blocks are retained temporarily upon the surface 21 by the retaining wall 25 which is bolted, through selected holes, to vertical members 24 carried by horizontal radial arms 23 secured to the uprights 5, a wear strip 34 being attached to each arm 23. The sinter blocks are removed from the shelf 22 to a hopper 38 by adjustably pivoted scrapers 35, the hopper discharge 39 being on to a belt conveyer 40. The removal of the lower layer of sinter blocks by the scrapers 35 permits the adjacent layer to gravitate on to the horizontal shelf 22. Water spray pipes 41, one being shown, may be arranged around and above the surface 21, or it may be desirable to have one spray just ahead of the scrapers, so that the water cooling follows a period of at least one revolution of air cooling. The sintering machine s discharges into a hood h comprising a fines bin b having a closable discharge shoot c, a grating g extending across the bin b and a sinter discharge shoot l leading to the shoot 32 which is provided with an outwardly swinging gate 33. When the cooling apparatus is used for cooling granular material, the wall 25 is adjusted, according to the angle of the repose of the material, so that spilling of the material over the edge of the shelf is avoided.
