Title: Improvements in or relating to transverse flow fans
IPC: F04D17/04
Filed: 1962-01-25
Abstract: 988,712. Transverse-flow fans. G. DATWYLER. Jan. 25, 1962 [Jan. 25, 1961; Aug. 15, 1961; Oct. 17, 1961], No. 2906/62. Heading F1C. In a transverse-flow fan, the open arc of the rotor periphery between the beginning and end of the high pressure side in the casing is greater than 180 degrees, and the outer wall of the casing enclosing the high pressure side of the fan is of substantially spiral shape, the mean flow line in any plane perpendicular to the rotor axis starting at the centre of the inlet at the low pressure side and continuing through the rotor axis to the centre of the outlet at the high pressure side being deflected by more than 130 degrees, the casing having a wall separating the inlet and discharge sides and extending inwardly in a direction making an angle of from 45 to 90 degrees with the radius of the rotor, the rotor having its interior clear of guiding means and the rotor circumference being free from adjacent parts extending along the circumference. In the fan shown in Fig. 3, the portion of the rotor periphery between the beginning 4 and end 3 of the high-pressure region 7 subtends an angle a which is greater than 180 degrees and preferably lies between 220 and 270 degrees. The mean flow line 5 starting at the centre line of the intake opening, passing through the rotor axis, and continuing along the centre line of the highpressure chamber and ending at the centre of the outlet, turns through an angle of more than 130 degrees, the angle shown being about 180 degrees. The spiral casing 1 may be of logarithmic spiral form. This arrangement prevents the pressure from decreasing as the mass flow decreases at low values of the mass flow, and the maximum pressure therefore occurs when the mass flow is zero. This allows two or more fans to be operated in parallel without the flow through one of them reversing when the mass flow is low. Wall 8, which may be straight or, as shown, of ogee shape, is so disposed that the cross-sectional area of the outlet decreases from the edge 3 onwards, the reduction in transverse width from the edge 3 onwards advantageously being approximately 10 to 20 per cent of the rotor diameter. This prevents the tendency for the vortex 6 to extend towards the outlet and cause a reversal of flow in the vicinity of the edge 3. Alternatively, any other wall in the region of the outlet may be given a particular shape for this purpose. For the same purpose, openings 9 may be provided, and a guiding member, such as a guide vane 10 may be provided to guide part of the flow towards the edge 3. Fig. 6 shows a fan in which the wall 8 is replaced by a pair of walls 141, 151. A secondary flow passes between the walls 14<SP>1</SP>, 15<SP>1</SP> towards the rotor. This reduces the steep velocity gradient which otherwise occurs at the edge 3 separating the high-pressure and low pressure sides, thereby suppressing a sirenlike noise caused by the velocity gradient.

Convention date, Feb. 15, 1934. [Class 106 (i)] A polar planimeter is mounted on one of the guiding arms of the drawing head of a known form of parallelogram drawing appliance so as to enable the calculation of areas to be performed without removing the drawing to be measured from the drawing board. The drawing appliance as shown in Fig. 1 consists of parallel guiding arms 1, 1<1>, 2, 2<1> connected by a ring 4 and carrying a drawing head 5 with a set square 6 rotatable about the pivot M. The planimeter as shown in Figs. 2, and 3 comprises a running wheel 12 co-operating with a vernier disc 15 and driving through a worm gearing 13 a counting disc 14. The spindle 11 of the wheel 12 is mounted in bearings at the ends of arms 8 extending from a sleeve 7 adjustably mounted on the guiding arm 2 of the drawing appliance. The planimeter is longitudinally displaceable along the arm to maintain it on the drawing surface ; the sleeve is held in adjusted position by a spring controlled knob 19 co-operating with a corresponding indent 18 in the arm. When the planimeter is not in use the sleeve is rotated to raise the running wheel 12. The planimeter may be supported on the two guiding arms 2, 21, but such support must be pivoted so as not to interfere with the parallel guiding.

Abstract: 620,929. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 1, 1947, No. 3142. [Class 112] Welt guides. In order that the welt may lie flat round the toe of a shoe without the need for slashing or beating, the welt guide is arranged tc allow limited swinging of the welt in its own plane about the point of operation of the needle, the welt being pressed against the upper without its free edge being so tensioned as to distort it; the guide is particularly useful for welts of resilient material such as natural or synthetic rubber or similar compositions. In the form shown, for use in a machine of the kind described in Specification 17328/08, [Class 112], the guide comprises a member 14 guiding the inner edge of the welt 13 and an adjustable guide 18 engaging its outer edge; the guide 18 extends past the needle path to press the welt against the upper at the sewing point, and its guiding face is inclined away from that of the member 14 so that the welt can swing a little to allow it to fit closely against the upper. If the welt has a pre-formed attachment rib, as shown in Fig. 2 (in which it also has a storm rib) the guide member 14 is formed' with a suitable channel 36 to accommodate the rib, this channel being wider at the entering end so as to allow the swinging of the welt.

Title: Improvements relating to electric motor control systems
Inventor: SENHENN DEREK ALAN
IPC: H02P3/24
Filed: 1952-02-06
Abstract: 713,483. Control of A.C. motors. ENGLISH ELECTRIC CO., Ltd. Feb. 6, 1953 [Feb. 6, 1952], No. 3170/52. Class 38(3) [Also in Group XXXV] During dynamic braking operation, the primary winding 10 of a three phase induction motor is connected for direct-current excitation to the output stage of an amplifying exciter 11 which may be of the kind set forth, in Specification 579,570, [Group XXXV], the secondary winding 12 of the motor being connected to a rotor resistance controller 13. A control winding 11a of the exciter is supplied through rectifier 14 from the secondary winding 12 and is thus excited in accordance with the product of motor flux and speed. The winding 11b opposes the winding 11 a and is supplied from motor-driven tachometer generator 15 through rheostat 16 which is coupled to the controller 13. The rheostat 16 is arranged so that the full output of the tachometer generator is applied to winding 11 b when the controller 13 is in the higher torque range. For any given setting of the controller 13, assuming steady conditions, the voltage of the generator 15 will fall at a greater rate than that of the secondary winding 12 when the motor speed is reduced. The consequent unbalance of the excitation of the windings 11a, 11b, tends to reduce the stator excitation and so restore the ampere-turns of the two windings near to balance. This tends to maintain the flux constant irrespective of rotor current and gives a braking torque which, for a given speed, increases continuously with movement of the controller 13 to reduce the rotor resistance. The ganging of the rheostat 16 and controller 13 has the effect of extending the range of controlled braking torque. In an alternative arrangement, the amplifying exciter may have a single input winding. The Provisional Specification refers to the use of a magnetic amplifier.

Abstract: 1,211,080. Ratchet clutches. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 15 Jan., 1968 [20 Jan., 1967], No. 3180/67. Heading F2C. An hydraulically operated one-way multidisc friction clutch, particularly for the additional drive of a standby generator by a gas turbine, comprises intercalated friction discs 17, 26 respectively splined to a driven shaft 10 and a housing 23, a presser-piston 28 disposed in the housing and leftwardly axially shifted on admission of pressure oil to the right-hand chamber of the housing through stationary and rotary feed lines 39, 43, a rotary lost-motion dog coupling 33, 34 between the housing and a driving shaft 11, and a rotary valve disposed between the feed lines 39, 43 and formed by radial ports (44), 45 respectively in the driving shaft and a spool 22 housed in the driving shaft and fast with the housing 23. The arrangement is such that with the driven shaft 10 overrunning the driving shaft 11, slipping drag between the friction discs 17, 26 in their disengaged condition causes the dragged housing and the driving shaft to assume a relative position at one end of the travel of the lost-motion coupling 33, 34 such that the valve (44), 45 is closed, and when the driving shaft overtakes the driven shaft the driving shaft and.the dragged housing assume a relative position at the other end of the travel of the lost-motion coupling such that the valve (44), 45 is opened and clutch engagement is effected. A further valve which comprises further radial ports 41, 42 respectively in the driving shaft and the spool 22 and which opens and closes respectively when the valve (44), 45 is closed and opened provides for clutch disengagement venting of the housing right-hand chamber through a stationary line 40. Oil at low pressure is continuously admitted to the left-hand end of the housing through a stationary line 16 and rotary lines 12, 13 to hold the presser-piston rightwardly in the clutch disengaged condition, and the discs 17, 27 may be continuously oil bathed through radial lines 19, 20. In an alternative embodiment (Fig. 5, not shown), a spring (50) is provided to rotationally bias the lost-motion coupling 33, 34 and thereby obviate engagement shocks.

Abstract: 751,505. Thread brake. SULZER FRERES SOC. ANON. Feb. 4, 1954 [Feb. 7, 1953], No. 3291/54. Class 142 (2). A periodically-acting brake shoe 18 has an off-position (as shown) and two braking positions in which it presses the thread 30 against a steel strip 10 loaded by a spring 15, thereby deflecting the strip as indicated at 10a and 10b. The shoe is actuated by a cam 25 having dwells at three radii r1, r2, r3; the braking force produced at the position 10b under the influence of a spring 23 can be adjusted by a stop screw 26 which prevents the follower 24 from reaching the radius r3. The parts of radii r1, r2 may be on separate cams so that they can be turned relative to each other to alter the duration of the dwells. The thread 30 may traverse the strip 10 longitudinally instead of transversely as shown. The shoe 18 may be fixed and the mounting of the strip 10 raised and lowered by the cam. The shoe 18 may be moved to two positions, and the mounting of the strip 10 moved by a second cam to give condition 10b, or the second cam may increase the tension of the spring 15. Reference has been directed by the Comptroller to Specifications 605,475 and 638,587.

Abstract: 220,592. Amundsen, I. Aug. 16, 1923, [Convention date]. Refrigerating, absorption machines and pro. cesses for.-In a machine working on the reversing system, the water tank 21 for the condenser coil 3 is provided with two outlets at different levels, the lower one communicating with a cooling-coil 24 in the generator-absorber 1 through a valve 13 controlled automatically for normal working, while the upper opening leads to the same coil and supplies water thereto when the automatic opening of the valve 13 is delayed through mis-operation. The invention is described as applied to apparatus wherein the valve 13 is controlled electromagnetically according to the level of liquor in the generatorabsorber 1, as described in Specification 210,448. The flow of cooling-water through the upper outlet 23 acts. upon a suspended member 31 in the pipe to control a switch 29 in the circuit for the heating and normal control of the apparatus, so that the heating is positively interrupted even should the normal automatic control fail to act at the propertime.
