Title: Improvements in or relating to flaps for aircraft
IPC: B64C21/08
Filed: 1939-02-24
Abstract: 543,044. Controlling aircraft. MERCIER, P. E. Feb. 24, 1939, Nos. 6227 and 6228. Convention dates, Feb. 24, 1938 and Jan. 31, 1939. [Class 4] Control mechanism for a camber varying wing flap is adapted to displace the axis of rotation of the flap in a direction away from the wing edge both when the flap is pivoted upwardly and downwardly. A substantial deflection of the flap may thus may be obtained while avoiding a gap between the edges of the flap and wing in the normal position. A link or lever 1 that supports the flap 2 by a pivot 3 is slidable between rollers 4 mounted on a pivotal support (not shown) to permit pivotal movement of the link 1. A lever 9 pivoted at 11 is connected by a link 12 to one arm 13 of a bell-crank lever the other arm 13<SP>1</SP> of which is connected by a link 15 to the flap 2 at 16. The members 12, 13 are normally in alignment so that movement of the lever 13, 13<SP>1</SP> in either direction to deflect the flap upwardly or downwardly causes the pivot 3 to be displaced away from the wing. The lever 13, 13<SP>1</SP> is operated by a cable 20, 21 passing round a pulley 19 on the spindle 18 of the lever. An elastic return member 24 may be provided. In a modification, the arm 13 of the lever 13, 13<SP>1</SP> is directly connected by a link to the pivot 3 of the flap and this pivot is suspended by a link from an extension of the upper part of the rear edge of the wing. The arm 13 and link connected thereto are normally substantially in alignment so that the pivot 3 moves rearwardly with deflection of the flap in either direction. A torsion bar may be combined with the spindle of the lever for returning the flap to normal position.

Title: Surgical and like absorbent swabs
IPC: B29C57/00
Filed: 1964-02-14
Abstract: 1,034,584. Surgical swabs. JOHNSON & JOHNSON. Feb. 14, 1964 [Feb. 15, 1963], No. 6261/64. Heading A5R. An absorbent swab comprises a flexible thermoplastic stick 16 at least one end of which is heat-fused and carries an absorbent wad 17, fibres of which are embedded in the stick. The stick is hollow and has shallow longitudinal outer ribs 25 and is made of polypropylene, high density polythene or a vinyl polymer. Opposite sides of each end of the stick are heat-fused and formed with transverse grooves 22 by passage between electrically heated jaws 33, 34 each having a ribbed surface, the minimum distance between the jaws being slightly less than the outer diameter of the stick. Wad material e.g. cotton or rayon is wound on each fused end of the stick before it solidifies, so that fibres become embedded in the stick and thus secure the wad to the stick. In a machine for assembling the swabs, sticks are fed at a station w to peripheral recesses 32 in a coaxial pair of intermittently rotating wheels 29. The ends of the stick pass between the heated jaws 33, 34 at a station x and wad material is fed to the ends of the sticks at a station y and formed on the sticks at a station z. In an alternative form of swab, the ends of the sticks (Fig. 11, not shown) are fused by a flame to form peripheral end flanges, the wad material being wound on the ends of the sticks before they solidify.

Title: Apparatus for cutting glas sheets
IPC: C03B33/03
Filed: 1962-02-09
Abstract: In an apparatus for cutting sheet glass comprising a horizontal glass sheet conveyer, a glass scoring tool mounted in a pre-set position for scoring a moving glass sheet, and a pair of sheet stopping and aligning means spaced horizontally from each other in a vertical plane normal to the path of travel of the sheet with power means to move them parallel to said path while being maintained in contact with the sheet, sheet sensing means responsive to the arrival of the sheet at an upstream station actuate the power means to move the sheet stopping means downstream and further sensing means responsive to the moving sheet cause the power means to return the sheet stopping means from the downstream station to the unstreamstation. A glass sheet G is moved on to or placed on belts 16 of a conveyer 17 on which it is moved from left to right (as viewed in Fig. 1). As the glass sheet G travels, it first trips a switch LS1 and then its leading edge hits rubber discs 74 on heads 73 of one or both of two stop arms 54 mounted on carriages 40. If only one stop head 73 is hit the movement of the belts 16 causes the sheet G to pivot about this stop head 73 until its leading edge is squared by abutting both heads 73. A time delayed relay set in operation by the switch LS1 then releases an electrical brake 111 and operates an electrical clutch 112 causing a continuously running motor 124, via gearing and a chain 80, to move carriages 40 forward at a slightly slower speed than that of the conveyer 17. Carriages 40 continue to move at least until flanges 100 trip arms 63 to move them in a clockwise direction so that arms 55 can drop down, thereby moving down arms 54, bolts 71 and stop heads 73. The velocity of the glass sheet G returns to that of the conveyer 17 and, shortly after, clutch 112 opens and a second electrical clutch 113 is operated, reversing the drive from the motor 124 to the carriages 40 and moving them back until a switch LS2 trips and de-energizes the clutch 113. Just before the switch LS2 is tripped, wheels 57 (Fig. 4), ride upon cam-plates 75 to rotate shafts 53 until arms 55 are above arms 63, whereby the top portions of arms 63 are moved <PICT:0944865/C1/1> <PICT:0944865/C1/2> by springs 65 into a latching position.  The apparatus is then ready to take the next sheet of glass.  The position of the flanges 100 is pre-set according to the lengths of the glass sheets to be scored. A square tube 31, extending transversely across the apparatus and above the conveyer 17, carries a number of transversely adjustable cutter assemblies with cutter wheels 35. The tube 31 is raised and lowered pneumatically.  A suitable electrical circuit is disclosed.

Abstract: 471,546. Boots etc.; pounding-up &c. machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) March 6, 1936, No. 6750. [Class 17 (i)] A machine suitable for operation on the bottoms of boots and shoes, is provided with a rotatable smoothing or beating roll which is heated by friction between the ends of the roll and a non-rotatable member. In one embodiment of the invention a pounding roll 18, which has its peripheral surface divided up into a series of flat surfaces, is mounted on a shaft 10 supported in bearings 12 in a head casting 14, and driven by means of a pulley 16. The frictional means for heating the roll comprises two cone-shaped projections 28, preferably of fibre, which are mounted on collars 31, and which project into conical recesses 30 in the ends of the roll. Each collar 31 is provided with a pair of pins 32 which extend upwardly and downwardly, radially of the shaft and which engage the forked ends of levers 33. These levers are pivoted about pins 36 mounded vertically on the head casting 14. The rear ends of the levers are forced apart, and the fibre cones pressed against the roll, by a spring 38, which bears, at one end, against the rear end 42 of one lever through a washer 39, and, at the other end, against an adjustable nut 46 on the rod 48. The ends of the rod 48 pass loosely through holes in the ends 42 and 44, of the levers, the force from the spring being transmitted to the end 44 of the corresponding lever by means of nuts 50 which may be adjusted to take up the slack between the parts when the spring 38 is fully extended. In order to allow the cones 28 to move parallel to the shaft 10, the holes in the levers 33, which engage the pivots 36, are formed as slots. An adjustable table 54 is provided on which the work is rested whilst the forepart is pounded. A small, unheated roll 20 is provided on the shaft 10 for pounding the waist portion of the work, and a scouring wheel 22. also on the shaft 10, serves to remove excess material on the overlasted margin of the work.

Title: Improvements in or relating to controllers for electric motors
IPC: B66C13/24
Filed: 1928-03-05
Abstract: 300,064. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). March 5,1928. Constant-tension winding and paying-out apparatus.-A reversible electric motor for winding- up and paying-out a cable is controlled by the tension of the cable so as to pass automatically through successive stages of speed and torque, whereby the tension of the cable is maintained substantially constant. The winding-drum 10, Fig. 1, is linked through a tension-responsive member 12 to a pivoted sector 19 gearing with a pinion on the spindle of a master-controller, which in its successive positions varies resistance in the motor circuits. The linkage from the member 12 to the sector 19 includes a notched setting-sector 14 and a handle 21 for selecting the degree of tension to be maintained and for allowing manual operation of the master controller when desired. In the system described, a direct-current compound wound motor is associated with contactors and relays for giving four steps of speed in forward running, i.e., winding-up the cable, and five steps in reverse running, i.e., paying-out the cable. The forward steps are all effected by successively excluding resistances R', R<2>, R<3> in series with the motor armature M, the progression being contingent upon movement of the master control-drum in the corresponding direction and also upon the action of current-limiting relays SR<2>, SR<3>, SR<4>. The reverse steps are effected by first putting the motor armature in series with resistances R<4>, R', R<6> and in shunt with resistances R<3>, and then progressively increasing the shunt resistance and reducing the series resistance. At any stage of the control, a jamming relay JR can reinsert all series resistances automatically. A relay BR controls a brake coil BC.
