Title: Improvements in or relating to the construction of wing spars for aeroplanes
IPC: B64C3/18
Filed: 1927-11-28
Abstract: 281,657. Fiat Soc. Anon. Nov. 30, 1926, [Convention date]. Framework; planes and wings, construction of. -A wing span of the metal box type, comprising two C-shaped members joined throughout their length by top and bottom flanges is asymmetrically strengthened in such a manner that the maximum compressive stresses are kept smaller than the maximum tensile stresses. Internal reinforcing members of different sizes are distributed along the interior faces of the flanges in accordance with the compressive stresses present in the different sections so as to obtain a spar of uniform outer contour. The wing spar comprises two C-shaped portions 1, 2 with overlapping riveted joints at the top and bottom, the side webs being pierced with triangular openings 5. At the sections Q-Q and S-S where the compressive stresses due to blending moment are concentrated on the top flange, symmetrical reinforcing members 8, Fig. 5 are provided under this flange. At the section V-V where a wing strut is attached, the spar is strengthened by an internal box 12, Fig. 6 and by asymmetrical reinforcing members 13, 14. At section L-L where the compressive stresses are less than at section Q-Q the arrangement is similar to that in Fig. 5 but the strengthening members are smaller. Where an internal strut is provided as in section T-T, a strengthening rib 6, Fig. 4 is affixed to the attaching side and a small reinforcement 7 is provided on the opposite side at the lower flange. Where compressive stresses are distributed uniformly on both flanges as at section M-M, symmetrical reinforcements similar to those in Fig. 5 are provided at both the top and bottom. A similar arrangement is found in section N-N where plates 11, Fig. 10, entirely covering the flanges are added. An inside reinforcing box is used at the section I-I near the point of attachment of the spar.

[Class 38 (iii).] Series connected traction motors A., A6 are protected against continual slipping of one or the other by arranging reactors 31, 32 in shunt to the motors so as to form a Wheatstone bridge, in the diagonal of which is arranged a relay 33. If one motor slips, the voltage thereacross exceeds the voltage across the other, and consequently the relay 33 opens its contacts which are situated in the holding circuit of the main circuit breaker 11. The system is also shown applied to D.C. motors, there being used resisters instead of reactors to form the bridge. Also in the case of A.C. motors the bridge may be formed across the inducing field windings, instead of across the armatures. Specification 110,246, [Class 38 (iii), Electric motor control systems &c.], is referred to.

Title: Improvements in statistical and other calculating machines
IPC: G06K7/016
Filed: 1936-11-26
Abstract: 489,425. Calculating - apparatus. BROIDO, D. Nov. 26, 1936, No. 32390. [Class 106 (i)] In machines controlled by punched records the readings means for the cards includes a carrier member furnished with a number of impulse transmitting points arranged in spiral or straight line form so as to pass during the movement of the carrier across the line of indication, successively over each position along the line, and means for establishing a mechanical electrical or fluid pressure connection when an indication passes over a point and transmitting the impulse to registering apparatus which is controlled according to the instant at which each impulse occurs in an analyzing cycle. In one construction a record strip 1 is arranged against a pile of plates 4, and, wherever there is a perforation in the strip, a plate projects therethrough as shown at points 8. A disc 9 bearing contacts 14 rotates in front of the strip 1 in synchronism with cams 50 and gear segments 51. Each contact 14 will momentarily touch one particular plate during the revolution of disc 9 if the plate is projecting through a perforation. At the moment of this contact segment 51 is commencing to drive a wheel 52 and the contact operates a magnet 22 which moves levers 56 in order to engage clutches between wheels 52 and numeral wheels 60. Cams 50 serve to release the clutches. In one revolution of the disc 9 amounts corresponding to the positions of the perforations on the strips are thus transmitted to the numeral wheels 60 and added thereby. The strip 1 may be provided with embossments instead of perforations to avoid the necessity for plates 4. In an alternative construction the disc 9 is replaced by a plate bearing a diagonal line of contacts, the plate being passed in a straight line over the strip at right-angles thereto. In a non-electric construction the contacts 14 are replaced by pins which on striking a plate 4 are caused to project from the rear of disc 9. As the disc rotates these pins strike a trigger which operates levers 56 through link work. In a pneumatic construction the contacts are replaced by perforation 40 in the disc 9. Compressed fluid channels 42 are situated behind the strip 1 and wherever the latter is perforated a discharge takes place which moves a baffle 44 and moves levers 56 through link work. Specification 475,943 is referred to.
