Patent DK-35597-A (DK)
Inventor: HOLME HJORTH FINN
IPC: F42B4/20
Filed: 1997-03-26
Abstract: At the turn of the year, a good deal of personal injuries occur in connection with firing of New Year's fireworks or rockets from a launching ramp, traditionally constituted by an empty bottle. The bottle ramp is dangerous to use because of its relatively modest supporting surface in combination with an inserted rocket, the latter most often implying a centre of gravity situated relatively high up. An aid is provided for use in connection with firing of fireworks, in particular rockets, which is characteristic in comprising a fireworks footing 2 comprising an upwardly extending tube 32 having a suitable inner diameter and length whose lower end is anchored in a bracket 24 in the middle of a cross-shaped beam 4, 6. Hereby, a great improvement in stability is obtained during firing of e.g. New Year's rockets relative to the bottle ramp mentioned, and thus of the security as well. The ramp may further be utilised in connection with firing of bomb tubes, etc. by inserting a tube with a greater inner diameter 36 into the bracket 24. <IMAGE>

Filed: 1943-01-07
Abstract: 575,154. Radio navigation. HAZELTINE CORPORATION. Jan. 7, 1943, No. 354. Convention date, Feb. 26, 1942. Drawings to Specification. [Class 40 (v)] [Also in Group XXXVI] In a system for facilitating the blind landing of aircraft, a frequency modulated carrier is radiated from an aerial elevated above the ground, and apparatus on the aircraft receives the direct wave and also the wave reflected from the ground, the beat frequency thus produced varying with the height of the aircraft above the ground. The loci of equivalue control signals derived from the beat frequencies are hyperbolic surfaces and by selecting the beat frequency corresponding to the hyperbolic surface which is tangential to the ground beneath the transmitter, a pilot may land along the hyperbola by guiding the craft so that the selected beat frequency remains constant. In a modified system, Figs. 4, 5, 6 (not shown), frequency-modulated carriers of different mean frequencies are radiated from separate elevated aerials arranged at the same height but spaced along a line at right angles to the course marked out to be followed before landing commences. The apparatus on the aircraft is duplicated to respond to the two carriers, the final amplifiers of the two channels being connected in opposition to an indicator, which shows the pilot when he is flying in a vertical plane equidistant from the two transmitters. The equi-value hyperbolic surfaces of the two transmitters intersect in curved lines in this plane and a second indicator shows the pilot when he has reached the particular intersection line along which he should descend to the landing point, flying so that the reading of this indicator remains constant.

Title: Checkout counter for conveying packages
IPC: A47F9/04
Filed: 1962-01-10
Abstract: 937,450. Self-service checking counters. W. T. BRIGHAM, and L. GERWECK. Jan. 10, 1962 [Jan. 17, 1961], No. 902/62. Class 116. [Also in Group XXX] In a self-service retail store, a check-out counter for advancing packages from a packagedeposit location at one end of the counter to a package-check-out location intermediate the ends of the counter comprises a movable package-pick-up platform 34 and a stationary package-deposit platform 22. The movable platform 34 is formed of spaced members 44, eight of which fit between a series of platform members 36 forming the stationary platform 22. The movable platform 34 is mounted on a wheeled carriage 48 by links 56 and may be raised or lowered by a handle 60 pivoted at 62 to one of the members 44 of the movable platform. A customer having deposited packages P on the stationary platform 22, a cashier pushes the platform 34 from the lower to the upper end of tracks 30, 32 supporting the carriage 48. Further pushing the handle 60 causes it to pivot and raise the platform 34 which lifts the packages P from the stationary platform 22, Fig. 2. A stop 68 on a platform member 44 engages one of the links 56 and the platform 34 remains in the raised position when the handle is released. The handle is then returned by spring means (not shown) to the position in Figs. 1, 3. The weight of the packages and of the platform 34 causes the platform to move down the tracks 30, 32 until the first package engages a cross-member 26 provided at a checkout location 24. After recording the price of the first package, the cashier moves the package on to a discharge platform 28, the platform 34 now being free to move down the tracks 30, 32 until the next package is engaged against the cross-member 26 and is price-recorded. When all the packages P are cleared, the platform 34 moves to the lower end of the tracks and engages a stop 30b. The sudden halt causes the platform 34 to pivot on its links 56 and to be moved to its lowered position, Fig. 1. While the recording of the packages P is taking place, packages P1 (Fig. 3) of the next customer may be placed on the stationary platform 22 ready for removal by the platform 34. In a modification, Fig. 7, the handle 60 cooperates with a spring stop 184 and is provided with an extension 182 for engagement with a stop 164 on a carriage member 152. The arrangement enables the platform 134 to be moved from its raised to its lowered position in cases where the platform has not made its full travel. In a further modification, Fig. 8 (not shown), the wheels of the carriage are dispensed with and the carriage is supported on rollers which replace the tracks. In place of the inclined tracks to move the platform towards the check-out location 24, spring means may be used.

Abstract: 763,703. Bearings. UNITED AIRCRAFT CORPORATION. Jan. 12, 1955 [Feb. 10, 1954], No. 955/55. Class 12 (1). In a bearing comprising an inner race ring 16, an outer race ring 8 and bearing members 22 adapted to roll between them, one of the rings has its member-engaging surface out-of-round to produce at circumferentially spaced points a spacing between the member-engaging surfaces of the rings that is slightly less than the comparable dimension of the bearing member 22. A method of producing such a bearing comprises producing an outer race ring with a cylindrical inner surface, distorting the ring and forming a cylindrical outer surface on the distorted ring. The ring 8 is mounted in a cylindrical recess 36 in a supporting housing 6 which is sufficiently rigid to cause distortion of the ring 8 and produce an out-of-round inner surface thereon and is sufficiently resilient to permit distortion of the outer ring by the bearing members as they move between the rings.

Abstract: 1532192 Adjustable mirror mounts ESSILOR INTERNATIONAL COMPAGNIE GENERALE D'OPTIQUE 11 Jan 1977 [16 Feb 1976] 00957/77 Heading G2T A mirror 3, pivotable about fixed axis 10, is rotated by action of abutment 14 on lever 4 when lever 5 is rotated about fixed axis 12 by screw 16. The displacement of lever 5 is sensed by linear movement of contact 18 and is indicated linearly by instrument 19 (or alternatively the screw 16 is linearly calibrated). In the neutral position (i.e. as shown) the distance 10-12 is equal to distance 12-15. The geometry ensures that for relatively small angles the difference in subsequent readings of scale 19 is proportional to the tangent of the angle through which the beam 9 is deflected (= 2x the angle of deflection of the mirror 3). Fig. 3 (not shown) illustrates a further embodiment.
