Title: Improvements in the method of producing slider operated interlocking fasteners
IPC: B21D53/52
Filed: 1931-11-20
Abstract: 382,442. Sliding - clasp fasteners. WINTERHALTER, M., 19, Davidstrasse, St. Gallen, Switzerland. Nov. 20, 1931, No. 32240. [Class 44.] The interlocking members of a sliding-clasp fastener are made by stamping from a blank previously provided with longitudinal grooves b, c and ribs d, e which form the engaging projections and recesses in the finished members. The grooves &c. may be shaped to give stepped formation to the projections and recesses in the finished members. The burr formed in the stamping operation provides end-walls to the recesses, which are thus cup-like in the finished members. Preferably the members are stamped in pairs subsequently severed along the line m-m, Fig. 4. The groove sand projections on the original blank may be straight, Fig. 4, or curved Fig. 12, the recesses and projections on the finished members being correspondingly straight or curved. Figs. 2-4 show each member with a part a having a projection on one face and a recess in the other, and with arms c by which the member is clamped to the edge of the stringer. Fig. 5 shows a form in which the members 2 on one stringer 1 have projections 5 on opposite faces, the members 4 on stringer 3 having co-operating recesses 6 in opposite faces.

Title: Improvements in or relating to bomb dropping sights for use on aircraft
IPC: F41G3/24
Filed: 1932-11-15
Abstract: 413,338. Bomb - dropping sights. VICKERS-ARMSTRONGS, Ltd., and WATSON, J. P., Broadway, Westminster. Nov. 15, 1932, No. 32326. [Class 92 (ii).] Telescopic or open sights are adjusted to follow the target by the rotation of a handle the movements of which are modified by a height setting device so that, whilst the sights are moved in accordance with the ground speed of the aircraft, the handle is continuously adjusted according to "linear deflection," i.e. the horizontal distance between the target and the point of bomb release. Further, the adjusting movement of the handle is applied to an indicating or bomb-releasing device also driven at a speed proportional to the ground speed. In the apparatus shown, a sighting- prism 2 forming part of a periscope is moved in following the target by a constant-speed motor '29 which drives a disc 25 through roller 28 and balls 26, the diso itself driving, through balls 24, roller 21, and differential gear 19, a screw 17 connected with the prism by a slotted link 13, crank 11, arm 9 and links 7. The planetary pinions 22 of the differential gear may be adjusted for tuning purposes by a handle 36. The speed of the screw 17 being proportional to the ground speed (vg) and the rollers 26 being set by a dial 38 to a function of the height (fH) which is equivalent to the time of fall, it follows that the rotation of the handle 32 sets the balls 24 radially of the disc by an amount proportional to vg x fH which is the linear deflection. The rotation of the handle is conveyed through wheels 53, 52 to a screw 49 for setting a slide 43 carrying an electric contact 44 for indicating the bomb-release position and a second electric contact 41 for releasing the bomb. The slide is moved in accordance with the ground speed vg by gearing 56, 55, 54, 48, between the screw 17 and the slide. Means for correcting the sight for the components of trail due to drift comprise a Dumaresq analyser with a crank 60 adjusted about a centre 61 to the drift-angle 63 and having a crank pin set for radius 62 to the "tangent of angle of trail." The cosine bar 64 of the analyser applies one component of the correction to the slide 43 and the sine bar 65 applies a transverse movement to the cross wire 80 of the periscope graticule through links which correct for the sine of the angle of sight introduced by shaft 70. In a modification, Fig. 6, open sights 130, 140 are employed, the foresight 140 being carried by an extension 141 of the ground speed screw 98 which can be turned laterally for drift about an axis 142. The correction for trail is introduced by operating a dial 132 and gear 133, 134, thereby inclining a bar 131 carrying the adjustable back sight 130.
