Title: Improvements in or relating to Taper Leaf Springs
Inventor: SKERRY PETER
IPC: F16F1/18
Filed: 1966-09-08
Abstract: 1,151,585. Leaf springs. TOLEDO WOODHEAD SPRINGS Ltd. 29 Aug., 1967 [8 Sept., 1966], No. 40081/66. Heading F2S. A single leaf-spring suitable for use in a vehicle suspension has a cross-section which progressively changes along its length in such a way that (a) at each point along the length the sectional modulus (ratio of moment of inertia to deflection under load) is in fixed proportion to the bending moment which arises at that point when an attachment portion of the leaf is supported and a load-bearing portion is loaded. The cross-section is also such that (6) its centroid lies nearer to the tension side (i.e. the upper side when so loaded) than to the compression side. Fig. 3 shows the cross-sectional form on line III-III of the cantilever leaf-spring 1 of Fig. 1. Figs. 4 and 5 (not shown) depict the crosssections on lines IV-IV and V-V of Fig. 1; these have the same overall width w as the Fig. 3 section but successively smaller thicknesses t, the lower surface 5 in each case being-as in Fig. 3-of substantially parabolic form. Longitudinally the leaf is flat throughout on its tension surface and convexly curved on its lower surface. Modifications to the general crosssectional form of Figs. 3 to 5 are necessary at the attachment section II-II where it is clamped and at the load-supporting end sections VI-VI and VII-VII. Suitable cross-sectional forms at these points are depicted in Figs. 2, 6 and 7 (not shown). Throughout the portion between sections III-III and VI-VI the centroid of the crosssection lies at a depth 0À4t below the flat upper tension surface, as in Fig. 3. Variations in this depth and in the cross-sectional and longitudinal form are permitted provided the two conditions (a) and (b) above are met. In particular the transverse contour of surface 5 may be parabolic as shown or elliptical, hyperbolic, involute or cycloidal. Also the attachment point may be at the centre, in which case the progressive diminution in section thickness would be developed in both directions from the centre towards the ends.

Abstract: 1,071,232. Sheet delivery; stacking arrangements. ING. C. OLIVETTI & C. S.p.A. Oct. 2, 1964 [Oct. 8, 1963], No. 40116/64. Heading B6H. A stacking device for a document sorting apparatus wherein documents are stacked into a plurality of stationary boxes 10, Fig. 1 between a fixed plate 49 secured to the box and horizontal plate 59 yieldably urged toward said plate 49 is characterized in that each document 13 is introduced over a helical member 82 located between said plates the member being rotated about a vertical axis in a direction to cause said document to pass subsequently under said member 82. In operation the document 13 is advanced by driven rollers 22 co-operating with idling rollers 23 towards the boxes 10, an appropriate box being selected by a deflecting member 28 operated by an electromagnet 29. The member 28 deflects the document into the nip of feed rollers 34, 36 which pass it between lugs 44, 46 the latter curving the document to enhance its rigidity. The curved document is then introduced into the box 10 over the helical member 82, whereby the leading edge is guided by flanges 48 of the plate 49, and accidentally bent corner of the document may be straightened by an inclined bracket 74, before the leading edge is engaged by roller 56 urging the document for alignment with stationary plates 51, 52, Fig. 2. To prevent the document from forming a loop between the rollers 56 and plates 51, 52 lugs 71 of a bail 70 engage the document and brake its stroke. Subsequently a lug 76 of the bracket 74 and the end 78 of a leaf-spring 77 engage the leading edge and curve it concave downwards. The thus fully introduced document lies on the helical member 82, which since it rotates engages the document with one of the bent portions 84 and causes the same to pass through a corresponding notch 83 under the member 82 whereby the document 13 is finally stacked in the position shown by the dot-anddash line in Fig. 1. The plate 59 upon which the documents are stacked is attached to a pin 61 fixed in turn to a carriage 62 having rollers 63 engaging a vertical rod 64, the carriage being lowered by the stacked documents against the action of a spring 66 (Fig. 3) on emptying of the box 10 the carriage is urged upwardly against a stop 67. In a modification the bent portions 84 on the member 82 may be replaced by a full helix.

Abstract: 1373391 Antiskid braking systems: changespeed control NIPPONDENSO CO Ltd 3 Sept 1971 [25 Sept 1970] 41281/71 Headings F2F and F2D [Also in Division G1] An antiskid braking system or control system for an electromagnetic clutch in an automatic transmission includes circuitry for checking the system and comprises a logic circuit for applying a check signal to the skid control circuit to energize the brake pressure modulating valve and for detecting the energization to terminate the check signal, and a warning device responsive to the receipt of the signal, the check signal being  obtained by modifying the waveshape of a signal from a source such as a wheel speed detector and the duration time of said check signal being shorter than the operational time of the modulating valve. As shown a sensor 1 consisting for example of a toothed wheel of magnetic material and a coil wound on a permanent magnet disposed near the points of the teeth supplies pulses to a waveshaping circuit 2 which converts the sine wave signal into a square wave signal and feeds it to a NAND gate 3 the output of which is converted into a direct voltage proportional to wheel speed by a circuit 4. A logic circuit 5 determines the extent of decrease of wheel speed and a timing circuit 6 causes normal braking to be restored if any previous circuit fails. A logic circuit includes a synchronization circuit 10, a monostable-multivibrator 11, a reset set flip-flop 12, a warning device 13, timer circuits 14, 15 and 16, a power source switch 17 and the gate circuit 3. When switch 17 is closed the output signal from timer circuit 16 will reset flip-flops 10b and 12 and set a flipflop 13a causing warning lamp 13b to be lit. With the vehicle running and the circuitry in normal condition the output of the NOT circuit 16b in the timer circuit 16 assumes the "1" state and NAND circuit 10a produces a "0" signal so that the circuit 11 produces a "0" signal only for the predetermined time interval so that timer circuit 14 produces an output only for a predetermined time and then as timer circuit 15 applies a set pulse to RSFF 12 gate circuit 3 is closed causing the brake pressure control logic circuit to produce a pressure reducing signal and lamp 13b being lit. When things are normal lamp 13b flashes while the vehicle is being driven but remains on when the vehicle is at rest.
