Title: Toe piece for safety ski-bindings
IPC: A63C9/00
Filed: 1966-05-27
Abstract: 1,146,495. Toe-iron for safety bindings. H. MARKER. 27 May, 1966 [3 June, 1965], No. 23970/66. Heading A6D. A toe-iron for safety ski-bindings is characterised in that it can be swivelled about a vertical axis lying in the area of the heel, out of its normal position until it reaches either of two release positions without longitudinal movement, and does not release the foot until this angular position has been overstepped whereby the resistance of the spring is transmitted through at least one lever and an abutting member of the toeiron, which slides upon an edge of the lever when swivelling occurs, the lever and the spring being so constructed that when the swivelling occurs, the increase in the resisttance of the spring is approximately compensated for by the elongation of the lever arm between the lever fulcrum and the bearing point of the abutting member. In an embodiment, a long base plate 5 is arranged to rotate about a round plate 6, which is securely mounted on the ski 19 and lies in the region of the heel, the sole holder 7 being securely fastened to the base plate 5. A restoring mechanism comprises a cam plate 10 with a cam 24 which is held in its initial position by spring 15, and the roller 18 is supported in the pivot bearing 16, the pivots 11 and 12 being located in the end position of their associated guide slots 22 and 23. When the base plate is swivelled cam plate 10 will rotate about one of the pins 11 and 12 and the roller 9 will ride upon cam 24. The plate 5 can swivel freely about point 6 after release from the restoring mechanism. The member 8, in which roller 9 is supported, may be swivelled vertically about an axis 20 so that base plate 5 may be easily reintroduced into the restoring mechanism. Other embodiments are described in which (a) torsion springs are employed as the restoring element, whose free ends collaborate in each case with an abutting member of the toeiron and a fixed stop on the ski, and the sole holder member is pivotably supported on the swivelling plate and locked so that it cannot swivel until it reaches the predetermined angular position; and (b) bellcrank levers are employed as the restoring element, preferably pivotable about a common fulcrum, and which collaborate with one pressure or tension spring each and whose free lever arms lie around and bear upon the abutting member of the toe-iron.

Title: Improvements relating to electric signalling systems
IPC: G08B3/10
Filed: 1936-09-02
Abstract: 486,581. Electric signalling systems. CIANCHI, A. Sept. 2, 1936, No. 24088. [Class 40 (i)] In a system for transmitting signals to different parts of a large store or hospital, the various signals are constituted by unidirectional-currents of opposite polarity and interrupted alternating currents. Additional signals may be given by A.C.s of different strengths. The receiver of the system comprises lamps 10, 11, 12, 25, the lamps 10, 11 being switched across the mains M bv mercury switches 10<1>, 11<1> which are made responsive by rectifiers 13, 14 to positive or negative currents and the lamps 12, 25 being operated in response to A.C.s of different strengths. The unidirectional-currents are transmitted by the switch 2 over contacts 4, 5 which are connected over rectifiers 6, 7 and smoothing equipment to the secondary of the supply transformer 1. The A.C. signals of different strengths are transmitted by the operation of the switch 2 on to contacts 3, 3<1>, 311, those sent when switch 2 co-operates with contact 3<11> being repeatedly interrupted by an automatically operated mercury switch 16. The signals corresponding to contacts 3, 3<1> operate lamps 12 or 12, 25 through transformers 27, 28 and mercury switches 12<1>, 25<1> and the signal transmitted when arm 2 is on contact 311 operates lamps 12, 25 intermittently. An additional signal may be given on any one of the contacts 3, 3<1>, 4 or 5 by switching into circuit an interrupter 23. Further a time switch 23<1> may be used whereby a different signal may be transmitted. The signal received may be acknowledged by operation of a key 30 which connects a transformer 29 across the signalling line so as to vary the illumination of a lamp 22 which is lit by the signalling current. Specification 453,229, [Group XXXVII], is referred to in the Provisional Specification.

Abstract: 351,305. Range-finders. GES. FUR ELECTRISCHE APPARATE, Marienfelde, Berlin. Aug. 13, 1930, No. 24249. Convention date, Aug. 15, 1929. [Class 97 (i).] Calculating- apparatus determining the angles of elevation and lead for ordnance is continuously adjusted by making use of the fact that the visual ray from a target moving with constant velocity sweeps out equal areas in unit time. As shown in the Figure, the angular velocity wc, determined in the velocity measuring apparatus 2 through the spindle 1 engaged with the lateral drive of a surveying telescope, is transmitted to a multiplying gear 6. By means of the spindle 7 the distance Eo is introduced and squared by the cam body 8, and the value Eo<SP>2> is transmitted to the multiplying gear 6. The result spindle 12 of this gear adjusts the value Eo<SP>2>wo on a part of the gear 13. This result is shown on the scale 15. The angular velocity wn, found continuously in an angular velocity measuring apparatus connected with the lateral direction drive of a theodolite and introduced through the spindle 17, is continuously introduced into the gear 13, giving the value En, shown on the scale 22. The time of flight tf is obtained in the gear 27 from the distance En and shown on the scale 30. The value tf is then transmitted to the multiplication gear 34 into which is simultaneously introduced the distance variation d (E ) obtained from the distance indication of the spindle 20 by means of a speedometer 35 and shown on the scale 37, giving the resultant value T, shown on the scale 41 and transmitted to the differential gear 43, simultaneously adjusted to the distance En, giving the firing distance. This is converted in the gear 49 into the corresponding angle of elevation for the ordnance, which is shown on the scale 51 and may be transmitted to the guns by means of the transmitter 53. The value wn is supplied to the multiplication gear 54 and also the value tf, the result being indicated on the scale 59 and transmitted by the transmitter 57. Electrical calculating- apparatus, say electric resistances, may also be used.

Three dimensional composite pictures are apparently displayed in space by a projector in which photographs of serial sections or strata of an object are moved in succession through the projection gate for projection on to a screen which is scanned along the optical axis in synchronism with the motion of the photographs, thereby cyclically scanning the volume of the projected composite picture. Still or motion-picture images may be projected. In the apparatus of Fig. 3, a series of sectional photographs 94A-T are mounted on transparent plastics drum 92 rotating at 1200 r. p.m. Stroboscopic illumination is provided by a multiple-flash Xenon tube 52 triggered by timing marks 100 on the film detected at 102. The images are projected via lens 66 and mirrors 64, 70, 72, 74, on to the diffusing spiral segment surfaces 78, 80, 82, 84, of screen wheel 76. Rotation of wheel 76 causes the segmental surfaces to scan in succession through the position 16 where the sectional photographs are thus displayed as a composite 3-D picture. Drum 92 makes one revolution for the passage of each screen segment. The screen surface may comprise a single spiral, or may follow a helical path. A rotatable Dove prism 68 permits rotation of the projected 3-D image about the optical axis. A transparent plastics dome covers the region 16 of the projected image. Opaque photographs may be used.
