Abstract: 623,009. Automatic control systems for radar antenna. BENDIX AVIATION CORPORATION. March 11, 1946, No. 7501. Convention date, March 14, 1945. [Class 38. (iv)[Also in Groups XXXVIII and XL (c)]. In a stabilization system for a vehiclemounted line of sight device, the device is positioned by a single servomotor to which is applied a control signal, variable in response to the degree of craft pitch and bank and to the azimuth position of the device. As shown, Fig. 1, the artificial horizon or gyro-vertical comprises a spinning member in case 28 having trunnions 30, 32 carried in the gimbal ring 34, the trunnions 36, 38 of which are supported in the frame of the vehicle, e.g. an aeroplane. Axes 40, 42 are respectively those of bank and pitch. Bank pick-off 46 (Fig. 2) comprises rotor 52 mounted on trunnion 38 and stator 54 mounted on the aircraft frame. Similarly, the pitch pick-off 44 comprises the rotor 48 on trunnion 32 and the stator 50 on the gimbal 34, the voltages generated by both pick-offs being proportional to pitch and bank angles relative to the horizontal. Stators 50, 54 are connected, respectively, to stator windings 58, 60 of the variable inductive coupling device 56, the rotor winding 70 of which rotates with the shaft 26. The latter is constantly rotated by the motor 14 and carries the platform 12 which supports the radar antenna 10. The rotor 84 of the induction motor 22, on platform 12, is coupled to the shaft 18, carrying the antenna 10, through the linkage 20 and to the rotor 88 of the variable follow-back inductive device 90, through the motion reduction mechanism 86. The stator 92 of the device 90 is connected in series with the rotor 70 and the input of amplifier 76, the output of which supplies one stator winding 78 of motor 22. A second stator winding 80 of the motor 22 is supplied through condenser 80 from the same A.C. source as the windings 48, 52 and 88. In operation, a voltage is induced in winding 70, by the pick-off signals at windings 58, 60, which is amplified at 76 and applied to the motor 22 which rotates in response until the voltage developed in winding 92 neutralizes that in 70, whereon the motor 22 stops. The plane swept by the sight axis of the antenna 10 is therefore horizontal.

Abstract: 720,496. Shoe-upper stiffeners. MARCY, R. J. March 24, 1952 [March 24, 1951], No. 7559/52. Class 17 (2). Polyethylene counters are secured in a shoe counter by preparing or altering the surface, which is not normally readily susceptible to the reception of adhesives, by coating it with an adhesive and inserting the counter in the shoe upper without forming a permanent bond between the counter and shoe upper, and after or during lasting, adhering the surfaces to each other by the adhesive coating or by a further such coating applied to it. The adhesive may be thermoplastic and hardened prior to its insertion in the shoe upper, e.g. by cooling to room temperature and secured by heating the lasted shoe to a temperature between 140‹ F. and 160‹ F. for a period in an ageing room through which the shoe passes after manufacture. Alternatively, the adhesive may be of a tacky pressure-sensitive character applied by dipping the counter into liquid adhesive before inserting it into the shoe, so that during heel lasting relative movement of the counter may occur to position the counter correctly and the adhesive bonds the surfaces together under the lasting pressure. In a further form, a coating of a substance having high adherence to polyethylene and which dries or hardens to a surface receptive to adhesives, such as latex, animal glue, paste &c. is applied to the counter and allowed to dry and the adhesive (latex, glue, &c.) applied between the counter and shoe upper or by dipping the counter at the time of lasting to bond the surfaces together.

Abstract: 1402963 Making carrier bags BRITISH CELLOPHANE Ltd 15 Feb 1974 [16 Feb 1973] 7800/73 Heading A4G [Also in Division B5] A seamless tubular film of a synthetic thermoplastic material, especially polyethylene polypropylene or poly(vinyl chloride), having at least one band of quarter thickness than the remainder of the wall of the film is formed by extrusion through an annular orifice to form a tube, inflating the tube by a gas under pressure and contacting at least one cooled lubricated roller with a portion of the molten tube rotating said roller in such a direction that at the area of contact the roller surface is moving in a direction opposite to the movement of the tube so as to solidify that portion and inhibit further thinning relative to other circumferential portions of the tube and cooling the tube. In Figs. 1 and 2, tube 3 is extruded through a die 2, collapsed by a pair of driven nip rollers 4 and air under pressure is admitted by pipe 5 to give a tube of predetermined diameter. The circumferential zone of solidification is indicated at 6 and the height of such line is determined by the position of the cooling ring 7. Between the frost line 6 and the ring 7 is positioned a rotatable bias roller 8 having a width corresponding to the width of a thickened band required to be formed in tube 3 and caused to rotate in contact with the tube. A stream of cooling liquid especially water, is directed on to the roller 8 and excess liquid collected in a trough 10. A thickened strip 12 is formed. In evaporating the lubricant assists the cooling of the tube 3. In Fig. 5 a modification is shown using two rollers 21 and 22 to give a tube as shown in Fig. 6. Fig. 4 shows a single roller which may be used in place of two side by side rollers 70 so as to give a crease line when the tube is collapsed. A laminate is formed by collapsing the tube (especially as shown in Fig. 6) followed by hot calendering. Carrier bags are formed by collapsing the tube 3 (now tubular film 1) in Figs. 1 and 2 by the nip rollers 4 at such a position that a crease line passes centrally through the band 12 slitting through the crease line (Fig.3) at the band 12 with a knife 15, forming transverse seals 16, at spaced intervals, forming cut-out hand holes 17 in the thickened edges 18 at the mouth of the bags 14 and then cutting off individual bags by cutting centrally through the seals 16.

A method for the production of radiator panels having corrugations includes feeding panel blanks between one or more pairs of cooperating rollers, the surfaces of said rollers being shaped so that they co-operate to corrugate the said panel blanks, said corrugations being arranged so that on a pair of panels being superposed and joined together, a closed system of ducting is provided around which liquid may flow. Panel blank strip 9 is corrugated between rollers 1 and 2 having at their central parts axial flattopped and bottomed ridges 3 and recesses 6, the height of which is about one quarter the spacing between adjacent corrugations, the diameter of the rolls being from eight to twenty times this spading. Annular ridges and recesses at the ends of each roller 1, 2 form longitudinal edge channels 12 in the strip which connect the transverse corrugations. The blank passes between pre-treatment rollers 10 having shallower transverse ridges and recesses than the rollers 1, 2 before passing to these rollers. The rollers 10 may have a lower peripheral speed than the rollers 1, 2 so that the blank is stretched therebetween. After the blank has been corrugated by the rollers 1, 2 it is straightened, the edges are cut and it is severed into suitable lengths for forming radiator panel halves. The halves are superposed in pairs and welded around the rims and in the corrugations to form a radiator with parallel ducts joined by transverse collecting ducts'at the ends. In a modification, Fig. 6, the blank is passed through pretreatment rollers 13 to rollers having central transverse corrugation sections 15 and cylindrical end sections 16, and to rollers 17, which groove the 'longitudinal edges, and then to straightening rollers 21.
