IPC: B04C7/00
Filed: 1949-02-17
Abstract: 657,452. Centrifugal separators. TRIGGS, W.W. (Sturtevant Mill Co.). Feb. 17, 1949, No. 4352. [Class 23] The separator comprises a rotary distributer 4 below the inlet 12, means to create fluid flow through the apparatus, rotary selector 15 which controls the size of panticle discharged through the outlet 22, and variable-speed mechanisms for driving the selector, distributor and fluid-current producing means. The latter in Fig. 1 is a fan or blower 20, beyond an adjustable throttle valve 27, driven by a pulley 21 independently of the rotary selector. The exhaust side of the fan 20 has a duct 23 'which delivers material that has passed between plates 16, on the rotary selector, tangentially into a collecting chamber C. Theouter shell 3, of the inner casing. extends well below vanes 25, which guide gases passing into an inner chamber S and may be arranged radially to slow down the' gases. Solids are thus caused to slide down the inner sides of walls 2<SP>1</SP>, 3<SP>11</SP> to outlets 26, 24. The selector 15 has axial plates 16 extending to an upper plate 17, pillars 18 being arranged between the plates. In place. of the plates 16, which may be adjustable, other plates 31, Fig. 6 (not shown), containing holes may be used. To prevent leakage of dust-laden gas around the selector 15, the top plate of it it, 28, is provided with radial vanes 30 which cause an outward flow of gas. Dimension of various parts of the separator are given in the Specification.

Title: Improvements in or relating to perpetual calendars
IPC: G04B19/257
Filed: 1946-02-13
Abstract: 607,991. Date-indicators. FARR, J. A. Feb. 13, 1946, No. 4518. [Class 106 (iv)] A mechanically-operated daily-changed dateindicator comprises constant-speed mechanism for driving a shaft 7 to reciprocate an eccentrically mounted pawl 9 and for driving three co-axial cams at different speeds so that three troughs 12a, 13a and 14a, one in each, are aligned once a day, when three cam followers rigidly mounted on a shaft 18 will be displaced. Through linkwork 19-22 this daily displacement will cause the reciprocating pawl 9 to engage a ratchet 10 and advance a setting shaft 11 against a spring to drive day-number units and tens drums, while a pawl 20 in the linkwork may actuate a ratchet 23 to advance a day-name drum. As the setting shaft 11 is advanced daily it is held against its returning spring by one of a series of detents such as 26 co-operating with its associated disc in a series 30-33 fixed on the shaft 11 and having 31, 30, 29 and 28 teeth respectively, one, 30b-33b, in each case being larger than the remainder. At the end of the month the appropriate large tooth knocks the operative detent free from an associated restraining latch such as 35 and through a pawl and ratchet device, with detents to prevent reverse rotation and over-feed, the shaft 11 causes the month-name drum to advance and advances a shaft bearing rigidly four selector discs 40-43 having 48 projections 40a disposed round their peripheries equally spaced and distributed between the four discs according to the distribution of 31, 30, 29 and 28 day months in a cycle of four years. Manual resetting means are provided and the device may have a clock embodied therein.
Patent GB-490677-A (GB)
Title: Improvements in machines for winding thread or yarn
IPC: B65H54/34
Filed: 1937-02-16
Abstract: 490,677. Winding yarns &c. HOLT, Ltd., T., and HOLT, H. Feb. 16, 1937, No. 4606. [Class 120 (ii)] In a machine for winding thread or yarn upon a cone, driven by a revolving drum, by a reciprocating thread guide, means are provided for automatically raising the yarn out of the path of the guide on breakage of the thread and at the end of the winding and for ensuring that winding movement is imparted to the varn in advance of the downward movement of the thread into the path of the traversing thread guide, such means comprising a rod 36 located in proximity to the path of traverse guide 16 and hingedly connected at one end 36<1> to a part of the machine frame, a rod 37 connected to the other end of the rod 36 and connected at its lower end to a trigger 39, a lost motion connection 41, 42 between the trigger and a link 43 pivoted to an arm 25<11> extending from the usual trip mechanism for operating the knock-off mechanism of the machine, and a detent 44 with which the trigger 39 is adapted to engage ; the lost motion connection permits a time lag between the initial movement of the trip mechanism and the operation of the trigger. When the thread A terminates or breaks during winding or is broken at the end of the winding, a feeler a wire 30 on a pivoted lever 31 moves up and cam follower 33 on the lever moves into the path of a rotating cam 22 which moves the lever 31 and a lever 23 in which it is pivoted so that a stud 25<1> on the trip lever 25 moves from the horizontal part of a slot 23<1> in the lever 23 and allows a spring 27 to rock the trip lever 25 about its pivot 26 ; a pawl 28 on the lever 25 then engages a rack 29 on the knock-off lever 18 which raises the cone-holder 11 and cone 12 from contact with the driving drum 14. At the same time the trigger 39 is rocked to raise the rod 37 until a nose on the trigger engages the spring-pressed detent 44, which is mounted in the bracket 21, the rod 36 being thus raised about its end 36<1> to lift the thread out of the traversing thread guide 16 ; a further detent 45, controlled by a light spring in the bracket 21, engages below a hooked part of the rod 37 and assists in holding the latter in the raised position. When winding is recommenced by depressing a handle 35 to reset the knock-off mechanism, the slot 42 prevents movement of the rod 37 until the pin 41. is engaged by the end of the slot when the trigger 39 is tripped and the rod 37 falls by gravity or added weight and causes the rod 36 to fall and allow the yarn which is then being wound on the cone 12, to fall into the path of the traversing guide 16 and become threaded therein. The rod 36 may be arranged at an inclination so as to control the tension of the yarn as it traversed from the large to the small end of the cone or it may be arranged horizontally and carried by levers moving vertically in guides and operated by the knock-off mechanism.

Title: Improvements in the control of dynamo electric machines
Inventor: CORBETT JAMES PATRICK
IPC: B21B37/54
Filed: 1950-02-24
Abstract: 679,392. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd. Feb. 23, 1951. [Feb. 24, 1950] No. 4778/50. Class 38 (iii). [Also in Group XXXV] A rolling mill drive has a reel motor and a main mill motor (not shown) which are both supplied from a Ward-Leonard generator (not shown), the current in the reel motor armature 33 being compared with a reference current in field winding 34. For this purpose an exciter field winding 32 is connected across resistor 31 in the armature circuit of the reel motor, and the opposing winding 34 is connected across a potentiometer 35 supplied from a constant source 36. The output of exciter armature 37 is applied to field winding 40 so producing a voltage across armature 41 which is added to a constant voltage from terminals 42 for energization of the field winding 44 of the reel motor. A feed-back unit 45 supplies a stabilizing field winding 46. When the mill is operating at a steady speed a tendency for the reel motor armature current to deviate from a set value is substantially corrected by means of the field windings 32, 34. When it is desired to accelerate the mill, a push button 50 is actuated and causes a pilot motor 51 to move the field rheostat 52 of the Ward-Leonard generator to a new position, so increasing the speed of the main mill motor and allowing the reel motor to accelerate. If the reel motor armature current is kept constant, however, the tension of the strip would be reduced, and, in order to prevent this, an inertia compensating winding 53 is provided which allows increased reel motor current. Since the increase in voltage output of the Ward-Leonard generator lags behind the change in its field excitation, the application of voltage to the winding 53 is simultaneously delayed in order to avoid violet changes in the tension of the strip. Hence the winding 53 is connected across the armature 32 of an inertia motor having a separate field 23, so that upon actuation of push button 50, a voltage is applied through resistor 24 to armature 22. The voltage across armature 22 builds up slowly, so gradually increasing the excitation of the winding 53.

Abstract: 898,008. Colorimeters. PROCTOR & SCHWARTZ Inc. Feb. 12, 1959 [Feb. 13, 1958], No. 4912/59. Addition to 822,027. Class 97(1). In the method of monitoring the colour of a fluid bath as described and claimed in the parent Specification upon detection of deviation of the colour of the fluid bath from that of the standard, there are added to the bath colour constituents to restore the colour of the fluid bath and its sample to that of the standard. A feed back arrangement for so restoring the colour is shown. In this arrangement a continuous sample is piped from a mixing chamber 3 into a cell 7, and the colour of the sample is compared with that of a standard by the arrangement described in the parent Specification. Any colour deviation results in an error signal which is used to actuate the appropriate solenoid operated valve 2a, 2b or 2c in the pipe line from the tank supplying a colour constituent to the mixing tank 3. Each valve on being opened may either add unit quantities to the mixing chamber until the error has been corrected or add at one time the correct quantity necessary to meet the deficiency.
