Abstract: 1,262,500. Aerials. GRANGER ASSOCIATES. 18 June, 1969 [23 July, 1968], No. 30820/69. Heading H4A. An aerial system 10, Fig. 1, comprises a support tower 11 with guys 12, on which is a generally triangular supporting assembly 13, including three radially disposed booms 14, 16, 17. An upward extension 18 provides anchorage for downwardly extending guys 19, which are coupled to the booms by bridles 21. Catenary cables extend between the ends of the booms and support an array of radiating elements. As shown in Fig. 3, said array consists of a plurality of parallel dipoles 31 connected to a feeder 33 extending along the axis of the boom 14, said dipoles having extensions 29 at their ends which are carried along the associated catenary cable, forming L-shaped active members. The lengths of the extensions 29 may be made equal to the sags of the catenary at their particular dipoles (Fig. 5, not shown) and the said extensions are made of a load-bearing material and are connected by insulating means at each of their ends to form parts of the catenary cable (Figs. 4, 11, not shown). The dipoles may alternatively be connected to the centres of their extensions, forming T- shaped active members. In another embodiment, the catenary cables are continuous, and extensions at the ends of the dipoles are run in parallel with the catenary cable, the ends of the dipoles and of their extensions being supported within the said cable by insulating means (Figs. 8, 9, not shown).

Title: An improved air pressure system for controlling brakes and other apparatus on rail vehicles
IPC: B60T15/04
Filed: 1946-10-16
Abstract: 626,330. Fluid-actuated valves. CLAYTON DEWANDRE CO., Ltd., and RODWAY, J. Oct. 16, 1946, No. 30829. [Class 135] [Also in Groups XXXII and XXXIV] A self - lapping driver's valve in an automatic compressed-air brake system (see Group XXXIV) comprises inlet and release valves 48, 50 carried by a stem 49. In the release position of the handle 46, the trainpipe is in communication with the main reservoir through a connection 47, passage 76, valve 48, passages 52, annular chamber 53, passage 54, Fig. 7, valve 56 and passage 59, the valve 50 being seated to close a passage 61 in the rod 65 of a piston 62 passing ports 66 open to atmosphere. The piston 62 is normally held in the position shown by a piston 63 acted on by main reservoir pressure and having a rod 64 whose end abuts the end of rod 65, springs 69, 70 being interposed between the piston 62 and a third piston 71 abutting a shoulder 72 on the rod 64, which is formed with rack teeth engaged by a pinion 68 on the shaft 67 of the handle 46. Rotation of the latter to apply the brakes moves the piston 63 and rod 64 to the left so that trainpipe pressure acting on the piston 62 compresses the springs 69, 70 sufficiently to allow the valve 48 to close and to unseat the valve 50. The trainpipe pressure then drops until the valve 50 is reseated by the springs, the reduction in trainpipe pressure thus corresponding to the amount of movement of the handle 46. As the effort to move the handle depends on the difference between the forces acting on pistons 62, 63, i.e. a function of main reservoir pressure minus trainpipe pressure, this effort increases progressively and the driver is enabled to " feel " the application of the brakes.

Title: Improvements in or relating to time-base circuits
IPC: H03K4/68
Filed: 1962-08-14
Abstract: 949,535. Transistor sawtooth current generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 14, 1962 [Aug. 17, 1961], No. 31162/62. Heading H3T. The invention relates to circuits for generating a sawtooth current in a coil, of the type in which a capacitor which is charged from the supply source during the stroke is discharged resonantly during the flyback through the output transformer of the circuit and a switch, the energy thus transferred to the transformer and coils being discharged during the succeeding stroke through a diode into the supply source. According to the invention an overswing coil is connected in series with the switch and capacitor to slow down the transfer of current from the switch to the diode at the end of the flyback. In Fig. 7, during the stroke a capacitor C 1  is charged via inductor L 1 . Upon the occurrence of a pulse at the base of transistor T, the capacitor discharges resonantly into an inductive circuit including output transformer 2 and deflection coil L s . After a quarter of a cycle, the upper end of the coil swings positively until a diode D conducts, whereupon the transistor is cut off and a linear change of current takes place as the energy is returned to the supply source, so producing the sawtooth stroke. When the diode starts to conduct and before the transistor is cut off, a resonant circuit comprising C 1 , L 1  and an overswing coil L 2 , commences to oscillate. This causes the transfer of current from the switch to the diode to occur more slowly and thus prevents non-linearly of the stroke and allows time for the stored charge in the transistor to be removed. Where, as shown, the transistor is of the S.C.R. type the overswing coil also serves to terminate its conduction. Resonant-charging of the capacitor can cause voltage at its upper terminal to increase to three times the supply source value. Alternatively, the use of a large valued inductor will render the charging rate constant. The overswing inductor may be transferred to the connection between the lower end of the transformer and earth (Fig. 9, not shown) or, when the transistor is connected in series with the transformer, between the transistor and transformer (Fig. 9, not shown). In the latter ease by suitably choosing the value of the overswing inductance in relation to the transformer tapping and L 1 , distortion of the output wave may be avoided (Fig. 10, not shown). A series " boost " capacitor may also be provided (Fig. 11, not shown). The invention may also be applied to the alternative circuits shown in Specification 815,411. It is stated that leakage inductance could replace the overswing coil, but this is not in accordance with the invention. Specification 821,517 also is referred to.

Title: Improved continuous process and apparatus for the production of large quantities of absolute alcohol
IPC: B01D3/00
Filed: 1922-11-15
Abstract: 189,136. Barbet et Fils et Cie, E. Nov. 15, 1921, [Convention date]. Alcohol, dehydrating. -A continuous process for the production of absolute alcohol consists in mixing alcohol of 95-96‹ Gay- Lussac with powdered quicklime or other suitable dyhydrating agent and distilling the greater part in a continuous still, collecting the alcohol, and continuously withdrawing the remaining liquid mixture, diluting it with water and delivering it to a rectifier where it is exhausted of its alcohol which is concentrated to 96‹ and again subjected to dehydration. In the apparatus shown in Fig. 1 lime and alcohol are mixed in a. large stirrer A and delivered by a valve B and pump C to a heater worm JJ and thence to a continuous still E with steam-jacket F and stirrers. The alcohol is condensed in the heater D and cooler G and flows out through a testing- device H. Only about three-quarters of the alcohol are thus distilled, the remaining liquor being continuously tapped off by a pipe e, diluted with water bv a cock S and funnel T and delivered to a continuous exhauster K L, the lower part of which is provided with bubbling plates constructed so as to prevent incrustation with lime. The base M is heated by a steam-bubbler which drives the alcohol into the upper part L of the column, where by means of a reflux N it is rectified to 96‹ and may be withdrawn through a testing-device N<1>, and returned to the apparatus for further dehydration. The calcic mud collecting at the base M is passed into an extractor Q with float q operaing an exit valve R whereby a constant level is maintained in M. In the simpler form of the apparatus shown in Fig. 2, the preliminary reaction between the alcohol and quicklime is dispensed with, the crude alcohol being delivered direct to the upper plate of the column K through a heater X heated by wastesteam from the exhauster K. Pasteurised alcohol is drawn off from the column L by the pipe u to a measuring device U and thence to the still E, E<2> which carries a partition E<1> dividing the unheated portion E from the portion E<2> which is heated by the steam-jacket F. Quicklime is dropped into E in measured quantities by a rotating recessed plug-tap P. It is stated that the testing-device W also serves to separate any aldehyde products. If incomplete dehydration is required the pasteurised alcohol may be drawn off at U. Instead of quicklime, fused calcium chloride, anhydrous potassium carbonate, anhydrous sodium or copper sulphate or anhydrous sodium acetate may be employed.
