IPC: B21D17/04
Filed: 1925-11-05
Abstract: 262,569. Macfarlane, D. Nov. 5, 1925. Hollow-ware.-In an apparatus for rolling sheet metal utensils having a mouth of smaller diameter than that of the part to be operated on, such as kettles, of the type consisting of a pair of rolls one of which is mounted on a rigid arm and the other on a pivoted arm pressed down by a screw, the pivoted arm carries a block which may be moved into or out of engagement with the screw so as to allow of quick insertion and removal of the work. In a corrugating machine the roll A is mounted on a fixed crank arm B and the roll D on a shalt E carried by a housing F which is pivoted at G, and normally raised by a spring P. The shaft E is pressed down by a screw U engaging a block R on an arm S which is pivoted to the housing F at T so that it may be removed out of contact with the screw when the latter is stacked back. The housing F has rigid therewith a housing N for gears H, J. the shaft K having a cup L with a transverse pin M for engagement with pins m on a slidable clutch b when the roll D is in operative position. The work j is placed over the roll A with its mouth engaging a fixed or rotatable cup or ring k against which it is pressed by a plate g rotatable on ball bearings on an arm e mounted on a vertical pivot. The apparatus may be used for rolling down a ridge formed by welding the parts of the utensil.

Title: Improvements relating to ward-leonard systems for winding engines
Inventor: WOODLIFF GEOFFREY EDMUND
IPC: H02P7/34
Filed: 1951-11-28
Abstract: 709,835. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 25, 1952 [Nov. 28, 1951], No. 27933/51. Class 38(3) Relates to means for restricting the power input to, or the power output from, a Ward Leonard set comprising an A.C. motor 1M driving a generator G which supplies a winder motor M. The generator has a field winding GF energized from an excitation system GE having a winding GEF2 responding to the difference between voltages derived respectively from a reference potentiometer P1 and from a potentiometer P2 which is connected across the generator G. The excitation system GE also has a field winding GEF1 which opposes the winding GEF2, and, when energized, reduces the excitation of the field winding GF. When the power input to the motor IM exceeds a pre-determined value, a current transformer CT passes current through resistor R3 and rectifier S1 to the winding GEF1, this current being opposed by a fixed bias voltage obtained from resistor R2 and rectifier S2. Excess demand of power from the A.C. supply thus causes reduction of the generator excitation and of the acceleration of the winder motor. If the motor 1M is of the induction type its rotor current is indicative of the power the machine is supplying, so that a current transformer connected in the rotor circuit may be used to excite the winding GEF1 in a similar manner to that described, Fig. 2 (not shown). A synchronous motor driving the Ward Leonard generator may have field boosting apparatus for increasing the motor excitation as a function of the power taken from the line, such as is described in Specification 629,586, [Group XXXV]. The output voltage from this device may be used to measure the power demand and may be applied to the winding GEF1, Fig. 3 (not shown). In other embodiments the power-restricting winding GEF1 is excited in accordance with the product of the current and voltage output of the Ward Leonard generator. An auxiliary generator mechanically coupled to the winder motor and excited in response to the Ward Leonard generator current provides such an indication of the power obtained from the Ward Leonard set, Figs. 4, 5 (not shown). Means may be provided for restricting the excitation of the Ward Leonard generator when a voltage responsive to the generator current exceeds a reference voltage which may be reduced in a stepped manner by the actuation of relays responsive to increasing values of the current suppled to the motor driving the generator. Alternatively, the relays may be responsive to the generator voltage. In this manner, the maximum current output of the generator is reduced as the voltage applied to the winder motor increases, so that the A.C. power supplied to the Ward Leonard set is also restricted, Figs. 6, 8 (not shown). In another arrangement, the generator excitation is restricted when a voltage representing the sum of components respectively responsive to the voltage and current of the Ward Leonard generator exceeds a reference voltage, Fig. 7 (not shown).

Title: Shrinking machine
Inventor: GEIPEL UDO
IPC: D06C5/00
Filed: 1963-07-17
Abstract: 997,447. Finishing fabrics; textile treatment apparatus. PASOLDS Ltd. April 16, 1964 [July 17, 1963], No.28238/63. Headings D1L and D1S. A shrinking machine for tubular fabric a movable belt or chain 5 having projecting pins 11 to engage and transport the fabric 10, and feeding means to feed the fabric on to the pins 11 at a speed greater than that of the belt or chain 5 so that the fabric forms transverse folds thereon. The fabric 10 to be shrunk passes into a steam box 1 in which the fibres are moistened and expand whilst the fabric is passing over an internal spreader 2 preferably a flat framework carrying small wheels (not shown). The fabric then passes between steam heated rollers 3, on to a short conveyer belt 12 driven at the same speed as the rollers 3, under free-running wheels 13 having a brush or sponge rubber surface and on to the pins 11 on the segment chains 5 adjustably mounted so as to accomodate different fabric widths. The fabric is delivered on to the pins 11 at a speed greater than the speed of the chains 5, e.g. by up to 50% of the latter speed, to form transverse folds so that the fabric is free to expand and contract lengthwise. The fabric also sags between the chains 5 to form a longitudinal fold. The chains 5 transport the fabric 10 through mist spray apparatus (not shown) in which it is heavily sprayed with water containing wetting agents, then through a steam chamber (not shown) to distribute the water throughout the fabric and subsequently through drying and cooling chambers (not shown). A conveyer 6, running at approximately the same speed as that at which the fabric is fed to the chains 5, lifts the shrunken fabric off the pins 11 and it is then conveyed to a J-box 7 from which it falls to form a stack 9 by the reciprocation of rollers 8. In a modification (not shown), after the fabric has been engaged by the pins 11 the distance between the chains 5 is reduced to allow the fabric to relax. A stream of air may be directed on to the lower surface of the fabric to reduce the downward force of the weight of the damp fabric sagging between the chains 5.

Abstract: 820,721. Jet propulsion nozzles. DOUGLAS, A. Sept. 26, 1955 [Oct. 2, 1954], No. 28439/54. Class 110 (3). [Also in Group XXXIII] An aircraft with jet reaction propulsion or control means comprises apparatus for diverting the gas stream from a first direction of flow into a second direction, and means for varying the position of the diverted stream relative to a fixed point on the aircraft, in a direction parallel to the first direction. The Figure shows a jet pipe 1 with a cut-out 3, surrounded by a tube 4 having a port 6 leading to a duct 5 terminating in telescoping arcuate segments 7, 8, which are angularly adjustable to direct the efflux downwardly and rearwardly, arrow 10, downwardly, arrow 9, or downwardly and forwardly, arrow 11. An hydraulic motor 14 moves tube 4 axially through a rack 12 and pinion 13. Baffles 16, 21 pivoted on trunnions 17, 22 in tube 4 are geared to be moved together while remaining parallel, by an electric motor 18. In one position, duct 5 is cut off by baffle 21 and baffle 16 is aligned with the rearward gas flow. In another position, rearward flow is cut off by baffle 16, and the two baffles deflect the gas flow into duct 5. The tube 4 may be moved axially when the segments 8 are adjusted, so that the thrust of the deflected gases always passes through the aircraft centre of gravity or centre of pressure. In a modification, the tube 4 and duct 5 are of square section, but with circular section ends co-operating with an upstream circular section jet pipe portion of lesser diameter, and a downstream circular section jet pipe portion of greater diameter, the two jet pipe portions being axially spaced avoiding the need of the cut-out 3. In another modification, tube 4 is within jet pipe 1, the duct 5 protruding through cut-out 3, and is axially movable by hydraulic jacks. In another form, pivotal baffles movable across the end of a jet pipe are mounted on an axially movable sleeve surrounding the jet pipe. Alternatively, a reaction propulsion engine together with a jet pipe and means for diverting the gas flow to a branch duct, is bodily movable relatively to the airframe.

Abstract: 279,881. Lorenz Akt.-Ges., C. Oct. 28, 1926, [Convention date]. High-frequency machines; casings and frames; torsional oscillations of stator, auxiliary means for reducing. - To prevent the " trilling " of the beat note in a heterodyne receiver in cases where a high-frequency generator and a frequency - multiplying transformer particu - larly of the iron-core type are employed, the high-frequency generator is provided with means for reducing torsional oscillations or vibrations of the stator about the rotational axis : these oscillations, the directions of which are indicated in Fig, 1, are caused to a large extent by the unequal forces which are transferred by the rotation of the rotor to the stator casing through the bearings. The result may be achieved by the employment of some damping or compensating device, as shown in Figs. 2-4 in addition to mechanically balancing the rotor very accurately. Fig. 2 shows a damping mass Q, consisting partly of mercury, connected to the stator of the machine. Fig. 3 shows an eccentrically-rotating balancing mass M driven synchronously with the rotor and mechanically connected with the stator. The machine may be connected to its foundation plate by stiffening rods, or the base of the machine may be enlarged in the axial and transverse directions, as indicated in Fig. 4.
