Title: Improvements in or relating to rotary tipplers for railway waggons
Inventor: ROBSON ROBERT
IPC: B65G67/00
Filed: 1956-02-10
Abstract: 811,120. Rotary tipplers; securing wagons. GENERAL ELECTRIC CO. Ltd. Feb. 5, 1957 [Feb. 10, 1956], No. 4305/56. Class 78 (4). The top clamping beam 10 holding a wagon in a rotary tippler is carried by a pivoted lever 12 operated, during rotation of the tippler, by engagement with stops on a weighted ring 15 free to rotate relatively to the tippler. As illustrated the operating weight comprises a concrete beam 17 extending between a pair of rings 15 mounted on rollers 16 adjacent the end rings 1 of the tippler and carrying rollers 18, 19 which engage a pair of levers 12 carrying the top clamp beam 10. As the pivots 13 of the levers 12 are carried clockwise from the position shown by rotation of the tippler, a rubber facing 11 on the beam 10 is brought into engagement with the top of the wagon, after which the wagon pushes the levers 12 out of engagement with the rollers 18 and into engagement with the rollers 19 so that the rings 15 turn to raise the weight 17 which biases the beam 10 against the wagon. In the upright position illustrated, the weight 17 rests against a stop 20 and the levers 12 against the rollers 18. A platform 5 carrying the wagon is mounted by rollers 7 on tracks 8 so that when tipping commences gravity, assisted by biasing springs (not shown), moves the wagon against a side beam 9. The tippler is driven through one of its supporting rollers 4.

Abstract: 879,618. Cartridge magazines with feed mechanisms; ammunition packing. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 8, 1960 [Feb. 13, 1959], No. 4406/60. Classes 9(1) and 92. A magazine for automatic firearms has clips L of cartridges P which are inserted in superimposed layers and are pushed downwards by a conveyer device K so that the lowermost clip rests on a surface 54 of a member 56 which carries the clip down with the same speed and direction whilst it is being stripped of cartridges prior to ejection from the magazine. Turned-in edges 12 of the clips engage the base flanges of sets of seven cartridges. Each clip has a U-shaped external rib 13, and has spring-loaded retaining latches 15 and pairs of rollers 14 at either end. The magazine container 8 elevates with the cradle 6 of each of a pair of twin guns 9. It rotates in a bearing ring 5 in non-recoiling sideshields 4 on either side of a rotatable gun platform (Fig 1, not shown). The clips are loaded through the open top 18 of the container 8 so that their rollers 14 at either end slide in vertical channels 19. The nose of of the lowermost set of cartridges rest on the surface 54. Bars 24, 25 oscillated opposedly by a cam-wheel 36 carry spring loaded pawls 26 which engage the ribs 13 to push the clips L down the channels 19 (Fig. 6). Alternatively the pawls maybe on an endless chain as in Fig 10. The ribs on the lower clips engage counter-rotated helices 21 of opposite twist which regulates their downward motion whilst they are being stripped. Similar helices 52 engage the member 56 to move the surface 54 downwards in conformity. Stripping of the clips is effected by arms 72 on a pair of parallel endless chains 71 which engage the outermost cartridge P 7  and push it across the clip after the catch 15 has been released by means not shown. The chain 71 slopes downwards to cause the transverse movement of the arms 72 to conform with the travel of the clip down the helices. The ejected rounds fall on to hooks 82 on a pair of endless conveyer chains 81 and are carried up the guideway 84 to be loaded into their appropriate gun. The helices and conveyer chains are driven synchronously through shafts, bevel and pinion gearing from a spring accumulator (not shown in detail) intermittently replenished from an electric motor.

Abstract: 1302517 Detector circuits TELEVERKETS CENTRALFORVALTNING 30 Jan 1970 [30 Jan 1969] 4697/70 Headings H3Q and H3T In a detector for detecting the envelope of a modulated carrier current A a modulated carrier current is passed through at least two parallel branches 1, 2, the phase of the current is shifted in one of the branches 1 but not the other, the positive and negative half periods of the current in the branches are added respectively in a combined adding and rectifying device D3 D4, D1 D2 and a first amplifying device F2 alternately amplifies the sum of the positive and negative half periods. The first amplifying device F2 is activated from gate circuits Tr1, Tr2 which are actuated by a second adding device H, F1 which adds the currents in the branches whereby an output signal Ut is obtained from the first amplifying device F2 which corresponds to the envelope of the modulated carrier current. As shown the input signal A feeds via paths 1 and 2 the amplifier F1 which produces square waves at its output K which makes the transistors Tr1 Tr2 alternately conduct. When the output pulse from F1 is negative Tr1 is turned off and Tr2 is turned on and positive half periods are passed via diodes D3, D4 to the positive in phase input of the amplifier F2 which produces positive signals at the output Ut. Similarly when the output pulse from F1 is positive Tr2 is turned off and Tr1 is turned on and negative half periods are passed via diodes D1, D2 to the negative phase reversing input of the amplifier F2 which produces a positive signal at its output Ut. Capacitors C1, C2, C3 and resistors R1, R2, R3 may be added to act as filters so as to further improve the output fidelity. The output Ut may be connected to an instrument to compare the output signal with an upper and lower limit and if the voltage of the received signal is not within these limits a fault is registered. The detector circuits may be used for detecting the envelope of a frequency shift or frequency or phase shift modulated signal passed along a transmission line, such as a telephone line.

Abstract: 266,721. Soc. des Moulins de 1a Caulre. Feb. 25, 1926, [Convention date]. Flour, treatment by cooling.-A current of artificiallycooled air or cold atmospheric air is directed from a pipe h through the grinding apparatus i<1> of a mill, shown in diagrammatic plan in Fig. 2, and is also passed in countercurrent to the ground material in the ascending branches a of elevators conveying the flour to bolting apparatus o, Fig. 1. The material falls from the grinding apparatus through shoots k to the bottom of the elevators, which are there enlarged as shown at l to decrease the air velocity and separate the material. A part of the cold air enters at h', and after expanding in an enlarging passage n descends to about the middle of the branches a whence it flows by way of pipes f and a filter e to a fan c. Another current of air is drawn up the branches a to the pipes f. Where the air is artificially cooled it is passed through a refrigerator g to the pipes h, h<1>, but atmospheric air may enter by an opening w and leave by a valve x. The descending branches b of the elevators, which are of smaller crosssection than the branches a, are fitted with flexible baffles r surrounding the buckets, whereby the air is carried down and cools the empty buckets. Conveyers m are arranged in the pipe f to remove deposited material, and electrical pyrometers s, t and dampers q, v, Fig. 1, are provided to facilitate regulation of the cooling. In the Specification as open to inspection under Sect 91 (3) (a) the invention was described with reference to Fig. 1 (Cancelled). This Figure does not appear in the Specification as accepted.
