Abstract: 934,920. Kerr effect records. NATIONAL CASH REGISTER CO. April 25, 1962 [May 19, 1961], No. 15678/62. Class 40 (2). A Kerr record for use with apparatus such as described in Specification 883,936, comprises a base 12, successively coated in vacuo with a reflective silver layer 13 and a magnetic layer 14 of Fe-Co, Fe, Co or Ni whose thickness is of the order of one quarter of the wavelength of the incident radiation B1 and which is therefore optically transparent. The thickness of the layer is such that the rotated rays B20 reflected from the upper surface and B21 reflected from the layer 13 and twice refracted in the layer 14 interfere with a consequent improvement of signalto-noise ratio. The behaviour of the various materials for the layer 14 with thickness and in the presence or absence of the layer 13 are displayed graphically (Figs. 3-6, not shown).

Title: Improved tool for the bending, the curving or the cambering of the edges of sheet-metal and other metal pieces
IPC: B21D19/08
Filed: 1939-05-30
Abstract: 529,406. Flanging. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SED-EST. May 30, 1939, No. 15838. Convention date, May 31, 1938. [Class 83 (iv)] A tool for bending, curving or cambering the edges of sheet metal or like parts, comprises a pneumatic hammer on which is mounted an adjustable spring-controlled slidable support for a resiliently mounted backing member so as to avoid the formation of folds. The body 1 of a pneumatic hand tool provided with a piston 3, a follower 6 and a spring-returned hammer 7 has secured thereon a screwed sleeve 11 on which is adjustably mounted by screwed washers 15, 16 a sleeve 14. On the sleeve 14 is mounted a slidable sleeve 17 which is pressed by a spring 20 against a washer 18 screwed on the sleeve 14. The sleeve 17 carries an arm 22 on the end of which is mounted in alignment with the hammer 7 a backing member in the form of a tapered roller 27 mounted on an inclined bolt 24 pinned down by a spring 26. A flat or curved sheet 30 is held between supports 31, 32 in a vice. In order to flange the edge 33 over a straight or cambered edge 34 of the support 32, the edge is placed between the roller 27 and hammer 7 which is then set in motion so as to bend the edge gradually, the thrust being taken up by the resiliently mounted roller. During the progress of the operation the tool is turned so that the hammer remains perpendicular to the edge. The tool is displaced along the whole length of the edge to complete the operation. A curved flat bond may thus be converted into horse-shoe U-section form without causing folds.

Abstract: 567,961. Airscrews. FAIREY AVIATION CO., Ltd. Sept. 27, 1943, No. 15855. Convention date, Sept. 25, 1942. [Class 114] A variable-pitch airscrew is adjusted as to pitch by an electric &c. motor 52 rotating with the propeller assembly which drives a pair of inner ring gear-wheels 62, 66 dogged together and engaging planet pinions 84, 86 on a counterweighted spider, these pinions respectively engaging a gear-rack on the inner periphery of a ring 70 forming part of a support for skew gear-wheels 48 engaging skew gear-wheels 36 fixed to the propeller blade sockets, and an internally-toothed freely rotatable, ring 76 engaging this ring 70. Teeth on the outside of the ring 76 engage the skew gear wheels 48. The teeth on the inside of the ring 70 are fewer than those on the inside of ring 76, e.g. they are 59 and 60 in number, so that upon starting the motor 52, the rings 76 will be caused to advance or retard and so actuate the skew gear wheels to vary the pitch of the blades. The electric motor may be replaced by a. reversible hydraulic motor, as disclosed in Specification 491,041. In modifications : (l) the wheels 48 may be longitudinally concavely curved to the same radius as the wheels they engage ; (2) the spider may carry three sets of planet pinions symmetrically disposed. The blades are mounted in screwed sockets 20 terminating in cylindrical portions 26 held between flanges on a sleeve 6 mounted between a ring and a nut on the propeller shaft. The hub is first forged and then mounted in turn on the blade axes and turned by a cutting tool. The arms are then bored and threaded externally. The hub is then mounted on its main axis and its front and rear openings bored and it is finished internally, the front and rear surfaces milled and slots cut for the wheels 48. The hub may be formed in front and rear sections welded together. The Specification as open to inspection under Sect. 91 states that the ring 76 may drive the wheels 36 through shafts carrying toothed wheels and worms, or the worm may be replaced by a nut movable on a screw-thread on the shaft and pivotally supporting a block engaging a slot formed in an annular flange which replaces the gear-wheel 36. This subjectmatter does not appear in the Specification as accepted.
