Title: Improvements in or relating to propellent cartridges
IPC: B25C1/16
Filed: 1966-05-13
Abstract: 1,144,064. Ammunition cartridges. DYNAMIT NOBEL A.G. 13 May, 1966 [15 May, 1965], No. 21486/66. Heading F3A. A propellent cartridge for power-operated tools comprises a case 1 containing a powder charge 2 and having a closed front end and a detonator 4 in the rear end. The wall of the case is provided with longitudinally extending ribs 8 which are of greater radial thickness than the wall of the case. On detonation the case splits between the ribs and small loose fragments are avoided so that ejection and re-loading are facilitated. The cross-sectional shape of the ribs may be of various forms illustrated in Figs. 7a-7d (not shown) and there may be additional ribs on the inside of the wall in positions corresponding to those on the outside (Fig. 7d). The closed end may be of ogival shape as shown. In another embodiment, the closed end wall 9 is of flattened conical shape and the ribs extend over this end, tapering toward the centre. In a modification, the detonator is housed in a cup (16), Fig. 2 (not shown), containing a primer (15).

Title: An improved ration mixer for livestock
IPC: A01K5/02
Filed: 1932-08-02
Abstract: 405,657. Delivering measured quantities. HICKS, G. A., Shurburne House, Chichester, Sussex. Aug. 2, 1932, No. 21585. [Class 106 (v).] Moving - chamber apparatus for granular materials.-Feeding-devices for ration mixers of the kind having a plurality of hoppers containing different materials which are delivered to a mixing trough by means of pocketted rotatable measuring drums the number of pockets in which are suitably masked to control the amount of material that each drum delivers in one revolution to the mixing trough, comprise adjustable means for regulating the number of revolutions of the drums necessary to deliver a desired total quantity of food for feeding cattle or the like. As shown in Fig. 1, the measuring drums 9 are all mounted on a hand-operated rotatable shaft 11, each drum being formed with pockets 10, one or more of which may be covered by a curved shield 5 to control the amount of material delivered. A pinion 19 on the shaft 11 meshes with a spur wheel 20 on the axle 21, on which axle. are also mounted a rotatable and slidable drum 28, a pulley 23 carrying a weight 24, and clutch members 36, 37, a hook 25 on the pulley 23 being adapted to engage with an eye 26 on the drum 28, and a locking bar 29 being adapted to engage with any pair of diametrically opposite hooks 31a mounted on the casing 18. When the number of receiving pockets in each drum 9 has been suitably adjusted, the drum 28 is turned until the arms of the locking bar 29 are adjacent the number, on the face of the casing 18, which indicates the number of deliveries from the drums 9, whereupon the drum 28 is pushed inwardly until the arms of the bar 29 engage the hooks 31a adjacent the required number on the casing 18. The movement of the drum 28 causes the clutch member 36 to engage the member 37, and the handle 32 is then turned to discharge the contents of the drums, the pulley 23 at the same time winding up the weight 24 until the hook 25 engages the eye 26. The drum 28 is then turned to release the locking bar 29 from the hooks 31a, the weight 24 returning to its initial position for another action. The pulley 23 may be locked to the spur wheel 20, so that when the pulley 23 is freed from the drum 28, the weight 24 functions to turn the pocketted drums back to their normal charging position. In a modification, the pinion on the drum shaft instead of engaging a spur wheel, engages a toothed rack slidably mounted on the side of the hopper, the travel of the rack being limited by contacting with an adjustable stop element.

Title: Improvements in or relating to Aerials
IPC: H01Q21/06
Filed: 1967-05-09
Abstract: 1,186,786. Aerials. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 9 May, 1967 [12 May, 1966], No. 21605/67. Heading H4A. An aerial comprises four substantially equally sized vertically stacked aerial units each containing aerial elements arranged in a plurality of levels and energized with substantially equal amplitudes. The elements in all levels in the two middle units are fed in phase and lead or lag reference phase by 25 to 40 degrees. The elements in the two levels in the top and bottom units which are respectively directly above and below the two middle units are fed in phase and lag or lead reference phase by 10 to 20 degrees (their angular difference from reference phase is of opposite sign from that of the elements of the two middle units). The elements in the outer levels of the top and bottom units are fed at reference phase. It is stated that with this arrangement filling in of the area (in a vertical plane) below the main beam of radiation from the aerial is obtained. The effect may be enhanced by introducing phase differences between the levels of the middle units to give a progressively increasing phase lag from the top to the bottom of the two units. A suitable phase difference between levels is 140 degrees divided by the total number of levels in the aerial. Furthermore, similar phase differences may be introduced between all levels of the aerial. An arrangement is also described for feeding eight aerial elements disposed in two levels and constituting one aerial unit. By using 90 degree phase shifters and reversing some elements, a progressive 90 degree-phase difference between vertical pairs of elements is obtained. The vertical pairs or columns of elements may be arranged in square formation around a mast, for a rotating field aerial.

Convention date, July 19, 1929. [Class 4.] In an aircraft of the type in which the wing spars pass transversely across the fuselage and in which the wing profile partly or wholly intersects the fuselage, the intersecting portion of the wing to the rear of the main or rearmost spar is dispensed with in order to increase the space available for accommodation within the fuselage. In an application to a parasol monoplane, as shown, having a single spar wing, the wing nose-piece d and spar e are placed in a recess in the fuselage and connected to the upper longerons, shown in thick lines. The full height of the fuselage is employed for the passenger chamber a, luggage chambers f, g being arranged fore and aft respectively. The centre part of the wing forward of spar e may be used as a commercial chamber. An application of the invention to a low-wing monoplane is also described.

Title: Improvements relating to the catalytic cracking of heavy hydrocarbons
IPC: C10G51/02
Filed: 1947-08-09
Abstract: <PICT:0642325/III/1> Hydrocarbon oils boiling above the gas oil range are cracked catalytically at a relatively high space velocity to give a high yield of gas oil which is withdrawn from the system; and the cracked residue boiling above the gas oil range is passed, at a relatively low space velocity, through a second catalytic cracking stage where a high yield of good quality gasoline is obtained. The gas oil separated after the first stage may be used as Diesel fuel. An Iranian wax distillate is cracked, in the presence of steam, in reactor 11 which contains a synthetic silica-alumina catalyst at 900 DEG  F., the space velocity being 10.3 expressed as weight of oil per hour per unit weight of catalyst, and the reactor-outlet gauge-pressure being 10 lbs. per square inch.  The products are passed to fractionator 13 where gasoline and higher hydrocarbons are withdrawn overhead, and gas oil of Diesel index 20 is taken off through line 15.  The residue boiling above the gas oil range is separated as bottoms through line 16, and passed (diluted with steam) at a space velocity of 0.81 through catalytic reactor 20 where the same temperature and pressure are maintained as in reactor 11.  The products are passed to fractionator 22 from which gasoline and higher hydrocarbons are withdrawn overhead, and gas oil of Diesel index 7 is withdrawn through line 24.  The gasoline head fractions from fractionators 13 and 22 may either be stabilized separately, in fractionators 17 and 27, to give gasoline with octane numbers 77 and 81 respectively.  Or the two fractions may be united via line 25 and stabilized in fractionator 17 to give a single product of octane number 79.  Fluidized catalyst may be used in both reactors, the second reactor being operated with bottom catalyst draw-off, while the first is preferably operated by the upflow method in order to deal conveniently with the high linear velocities.
