Title: Improved method and device for the continuous wet treatment of artificial threads
IPC: D01D10/04
Filed: 1953-11-23
Abstract: A plurality of artificial threads are wettreated while moving parallel to and at a short distance from each other in a substantially horizontal plane, the threads being led under a liquid surface which is transported in the same <PICT:0758671/IV(a)/1> direction as the threads by means of a conveying device placed underneath the layer.  In one device, not shown, the threads are led in a horizontal plane beneath a pair of rollers through a layer of liquid carried by an endless belt having a channel section.  The liquid is directed on to the endless belt through a slit orifice extending over the whole width of the belt.  A trough having means for removing the liquid may be placed about the belt. The vertical position of the thread guide rollers and endless belt may be adjustable.  In a modification, Fig. 2, the endless belt 2 is supported beneath the surface of the liquid in a trough 1 by rollers 3 mounted on a pair of hollow buoyant members 18. The threads 10 are conveyed beneath the surface of the liquid in a horizontal plane over guiding rollers 11 and 12 which are constructed as swingable rollers with the rollers 14 and 15 respectively, the pairs of rollers 11, 14 and 12, 15 being pivoted at 13 and 13.  Spacers are provided for adjustment of the position of the endless belt relative to the rollers 11 and 12.  Liquid is admitted to the trough at 16 and removed at 8, the height of the liquid surface being determined by a height-adjustable gate 17. The upper surface of the endless belt moves in the same direction as the threads at or near the same speed and so conveys a layer of liquid with the threads.  Instead of an endless belt, parallel chains with attached plates may be used.  The belt may be driven through a flexible shaft from outside the trough or by a built-in hydraulic or pneumatic motor or one of the rollers 3 may be constructed as an electric motor of which the shaft is stationary and the housing rotates.
Patent GB-325073-A (GB)
Abstract: 325,073. Heyne, W. O., and British Electric Pari-Mutuel, Ltd. Jan. 12, 1929. Totalizators.-In an arrangement of electrically-operated escapements designed particularly for an extensive installation, each horse indicator possesses a number of sets of receiving escapements, the terminal elements of which serve to transmit impulses to the several escapements of a collecting set the terminal element of which controls the indicator. This cascade arrangement is applied separately to the several denominations of the indicator, and thus permits of the direct registration of bets of higher values. Means for effecting simultaneous operation of a grand total indicator are also described. The diagram shows three stations 1 - - 3 for receiving 1/ - bets, one (4) for 2/- bets, another (5) for 5/- bets, another (6) for 10/- bets, one (7) for ú1 bets, and so on. The horse indicator A, having units drum 10, tens drum 11, &c., is controlled by the various sets of escapements as follows. One set of escapements, 15, is wired up to the A contacts of the 1/- stations 1 - - 3, and the terminal element 19 of this set transmits the impulses received to one escapement of a collecting set 18, the terminal element of which in turn controls the units drum 10. Another set of escapements 16 is controlled as to some of its elements by the 2/- machines, and as to the remainder by further 1/- machines, the release movements of the former elements being double those of the latter. The terminal element of the set 16 is similarly arranged to transmit the impulses to another element in the collecting set 18. Similarly, a third receiving set 17 is allocated to the 5/- bets, and has a corresponding influence on the third element in the set 18. The tens drum 11 is controlled in similar fashion by a collecting set 22 summing the impulses received by the 10/- set 20 and the ú1 set 21, and the hundreds drum is likewise controlled but without the introduction of a collecting set, the single set 24 serving for receiving bets of ú5 and ú10. Transfer from one drum to the next is obtained by a separate escapement element (23, 26) in the collecting set, controlled by a contact on or connected with the lower drum. The grand total indicator T is controlled by series of escapement sets 30, 31, 32, &c., arranged similarly to those of the horse indicators, the individual elements of the receiving sets 30, 31 being connected respectively with the terminal elements of the collecting sets of the various horse indicators. Specifications 286,997, 287,767, 324,906, and 324,907 are referred to.

Title: Improvements in and relating to governing mechanisms for fluid-operated motors
IPC: G05D13/00
Filed: 1929-10-30
Abstract: 347,664. Governing prime movers. PARSONS, SIR C. A., GIBB, C. D., and HAILEY, P. M., Heaton Works, Newcastleon-Tyne. Oct. 30, 1929, No. 33006. [Classes 57 and 110 (iii).] In a governing mechanism of the type wherein for each steady position of the sensitive element there is a corresponding position of the throttle valve, means are incorporated in the transmitting mechanism between the sensitive element and the servomotor operating the throttle valve whereby a constant ratio is obtained between the movement of the sensitive element, from the zero position of its operative range, and the weight of fluid passing the throttle valve in unit time. The Figure shows a centrifugal governor 11 operating a throttle valve 2 through the medium of the servomotor. The pilot valve 7 and the rod 17 from the governor are pivoted to a floating lever 20 pivoted at 21. Two toggle levers 25, 26 are pivoted at 21, 28, their common pivot 27 being connected to the rod 7 at pivot 30. As the load on the prime mover increases, and the valve 2 opens, the point of application 18 of the rod 17 upon lever 20 being moved towards the pilot valve thereby progressively accentuating the movement of the valve 2 relatively to the governor sleeve 12. In modifications the toggle links are replaced by a bell crank or the pilot valve rod 24 or the rod 7 are connected to the lever 20 through cam faces so that the point of application is varied as the valve 2 moves. Furthermore the follow up of the pilot valve is transmitted by a cam attached to the power piston rod, said cam being shaped to obtain the required ratio of movement. An arrangement similar to that described in Specification 279,554, [Class 57, Governors &c.], is shown with the latter arrangement. An arrangement is also shown wherein the invention is applied maintaining constant extraction steam pressure from a turbine. The sensitive element may be responsible to changes of speed, load, pressure, volume, &c, and the refinement movement in the transmitting mechanism may be obtained by hydraulic, magnetic or electrical arrangements.
