Filed: 1973-06-27
Abstract: 1418708 Priority networks HONEYWELL INFORMATION SYSTEMS Inc 27 June 1973 [27 June 1972] 30657/73 Heading G4A A priority network for enabling the highest priority request device of a plurality of devices to gain access with a bus comprises logic circuitry associated with each device receiving simultaneous input signals from a plurality of higher order devices indicative of whether the higher order devices are ready to access the bus. As described each device, e.g. device N+4 receives signals B, C, D, E (Fig. 3) from four higher order devices which are fed to an OR gate 12.4 to generate a signal having a first state if one of the devices N, N+1, N+2, N+3 requires access, or a second state indicating that the device N+4 may gain access. If access is required OR gate 14.4 generates a signal for propogation to the next and consequently all succeeding devices. A clear priority net signal is generated to close AND gate 16 after the device which most recently gained access has had its address stored.

Title: Improvements in or relating to aircraft
IPC: B64C21/02
Filed: 1946-10-16
Abstract: 643,987. Controlling aircraft. STALKER, E. A. Oct. 16, 1946, No. 30796. Convention date, Nov. 26, 1945. [Class 4] An aircraft wing is provided with nose and tail flaps, and flap-actuating mechanism responsive to pressure difference at two spaced points on the upper surface of the wing between the flaps, whereby relative adjustment of the flaps in co-ordination is effected in response to variations in the pressure difference so as to maintain a predetermined pressure distribution over the wing surface. As shown, the invention is applied to a tailless aircraft with swept-back wings, the latter being of thick section and pronounced camber, to produce a substantially constant pressure over the major portion of the chord, as shown by the curve 86, Fig. 10, such a pressure distribution serving to reduce tip stalling due to outward airflow. The nose and tail flaps 6, 8 are hinged to the underside of the wing at points 100, 102 and the pressure control points 110, 112 on the upper wing surface are connected to bellows 118, 119 controlling a valve 120 which governs the supply of pressure fluid to a power jack 122 operating the flaps through links 104, 106. In operation movement of the tail flap 8 by the pilot modifies the pressure distribution on the wing surface, which is restored to its original form by the automatic operation of the nose flap 6. In order to reduce still further the tendency to tip stalling, the boundary layer is sucked through slots 130, 131 in the upper surface of the outboard wing portions, and discharged through slots 134, 136 in the inboard portions. The wing profile is derived from a symmetrical section, Fig. 9 (not shown), of which the leading edge portion is substantially elliptical in section.

Oct. 20, 1930, No. 31422. Convention date, Nov. 4, 1929. [Class 40 (ii).] To eliminate scratch noise the sound grooves of wax and like master records are burnished to smooth out irregularities without affecting the record form. This may be effected by a stylus lightly loaded and elastically pressed into contact with the record grooves whilst the record is rotated. If necessary the stylus may be rotated on its axis to increase the burnishing effect. The Figure' shows the burnishing stylus mounted in bearings 14 on the reproducer arm 8 and lightly pressed into record grooves made in a wax blank by a spring 13. The stylus is rotated by a cord 12 and pulleys from an air motor 6 supplied with compressed air by hose 7. In the working condition, the force pressing the stylus into the groove must never become less than the product of the needle point velocity and the needle point impedance over the frequency range of the record, and quantitative examples are given in the Specification. Specification 363,449, [Group XXXIX], is referred to, and the Specification as open to inspection under Sect. 91 refers to U.S. Specification 1,707,260.

Abstract: 477,725. Dressing fish. DANIELSSON, P., and AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. Nov. 17, 1936, No. 31499. [Class 28 (ii)] [Also in Group XXX] Fishes are eviscerated by subjecting them externally to a working or kneading operation to eject a part of the entrails from the cut head end of the fish, and then pulling on the ejected part of the entrails to remove the whole. As shown, the fishes are supplied from a magazine 39, 67 singly to pockets formed by plates 1 on a conveyer 60, the heads of the fishes being correctly positioned by an abutment plate 37 and then removed by the disc knife 51. The working or kneading on the fish may be effected mechanically or hydraulically, or both. Mechanical kneading is effected by rows of rubber fingers 14 carried on a rotary shaft, and is assisted by water-jets from nozzles 30 which jets may be continuous or pulsating. The part of the entrail thus worked out. is moved along, with the fish, by a helically grooved roller 16 and is received between rollers 27, 28 which pull the entrails completely out of the fish. The rollers 27, 28 are cleaned by a water jet 29. The rollers, conveyer and fingers 14 are driven from the shaft 4 through bevels 5, 8, 18, 10, 11 and appropriate belts, the valve controlling the nozzles 30 and, if desired, the nozzles also, being automatically oscillated to produce the pulsations. The magazine hopper 39 extends downwardly from a table 38 and feeds into a compartment having a fixed wall 41 and a wall 40 manually adjustable according to the size of the fishes by a screw 43. A sliding shutter 46 having a discharge opening 47 is operated by each plate 1 as it passes by the cam end 58 of the lever 55 which is pivoted at 54 and connected to the shutter by a rod 56. The passage of the plates 1 moves the shutter to the right and stresses the spring 57. When the cam 58 is released, the spring 57 moves the shutter to the left and brings the opening 47 into the discharge position. At the same time the shutter operates through a spring 52 to swing a flap 48 inwards to retain the fishes above the one being discharged. The fish drops into the pocket beneath the magazine, the pockets being sloped so that the fish slides into contact with the abutment plate 37. The fishes are held in the pockets by holders 31 pivoted to each plate 1 and urged into the holding position by springs. Cams 35, 36 engage arms 33 on the holders 31 to raise the holders for the release and insertion of fishes, respectively.
