Title: Multi band beam antenna
IPC: H01Q5/392
Filed: 1958-03-12
Abstract: 890,786. Aerials. HARLOCK, F. H. March 12, 1958 [July 19, 1957], No. 7886/58. Class 40(7). A directional aerial assembly capable of operation at a number of frequencies comprises a primary element pair D, E, director elements A, B and also C, and reflector element F, G. The director C is made of such a length as to be substantially effective only at the highest operating frequency it is proposed to use and the elements A, B and F, G have centrally arranged circuits Tl and T2 rendering them effective at all the design operating frequencies. Fig. 2 shows the arrangement of such a circuit for three operating frequencies. The values of the circuit components L1, C1, L2, and C2, are so chosen that at the highest of the design frequencies the two halves of the elements are electrically isolated, at another they are electrically connected and at the lowest they are connected by the circuit acting as a loading means to increase the effective length of the elements. It is stated that adding further circuit elements makes it possible to increase the number of frequencies at which the aerial will operate.  The feed to the element DE may be a 300 ohm balanced open line. The element does not resonate at any of the design frequencies and is only resonant using a portion of the feed line. Dimensions are given for an aerial effective at frequencies in the 10, 15, and 20 metre bands.

Title: Improvements connected with the pile cutting mechanism of looms for weaving royal axminster or moquette carpets and other tufted pile fabrics
IPC: D03D39/24
Filed: 1932-03-18
Abstract: 397,226. Pile-fabric looms. HEAD, T. W., 39, Whitburn Street, and SOUTHWELL, Ltd., H. & M., both in Bridgnorth, Shropshire, and PLATT BROS. & CO., Ltd., Hartford Works, Oldham. March 18, 1932, No. 8040. [Class 142 (ii).] In looms for weaving Royal Axminster, moquette, and like tufted pile fabrics, the rear knife 1 of the pile-cutting mechanism is primarily moved into alignment with a row of tufts, by means of a cam 10, and then held rigidly against abutment stops, during the shearing movement of the co-operating front knife (not shown), by a cam-actuated locking device. The knife-supporting levers 3 are connected to a pair of rearwardly extending arms 11 the forked extremities of which are slidably mounted on a shaft 13 that can be rocked by means of cams 27, 28 on the tappet shaft 22. When the cam 28 engages a bowl 26 on a pivoted lever 25, locking levers 30, fixed to the shaft 13 and provided with cam-faced shoulders 31, are lowered into engagement with projections 16 on the arms 11 so as to lock the knife 1 in its advanced position. With the continued rotation of the shaft 22, the cam 27 comes into operation to raise the levers 30 and permit withdrawal of the rear knife after the cutting operation.

Title: Improvements in or relating to remote control systems
IPC: H01Q1/30
Filed: 1943-05-21
Abstract: 568,624. Winding aerials. LEAR AVIA, Inc. May 21, 1943, No. 8110. Convention date, Feb. 25. 1942. [Class 40 (i)] [Also in Group XXX] An arrangement for use on aircraft for selectively controlling the extension and retraction of a trailing radio antenna by means of a reversible motor 120 comprises a setting knob 17 carrying a pointer 18 which when moved in either direction relatively to a dial 20 causes the motor to operate in the appropriate direction and to drive both the dial 20 and the knob 17 until the pointer 18 again comes opposite a zero mark 19. The reading of the pointer 18 against the dial 20 thus indicates the length of the antenna. The knob 17 is integral with a disc 42 carrying a pin 75 which normally lies between the forked ends 74 of a member 76 on the shaft of a cam 80. The cam is in unstable equilibrium in its neutral position and when displaced by rotation of the knob 17 it is urged by a spring 93 until the member 76 strikes a stop 94 or 95. The " in " and " out " windings 122, 123 of the motor are controlled by switches 83, 84 which are adjustably mounted at either side of the cam 80 and are operated alternatively by plungers 85, 86 when the cam is displaced to either side of its neutral position. The motor 120 drives the antenna reel 136 through an electromagnetic clutch 125 of an abruptly-acting type such as that described in Specification 549,552, [Group XXXV], the latter being in series with the motor so as to be energized and de-energized therewith. The motor also drives through a flexible cable 29 and worm gearing 28, 33 the dial 20, which is frictionally-coupled to the knob 17 so that as the latter returns to normal the pin 75 restores the forked member 76 and hence the cam 80 to its neutral position. Limiting switches 142, 143 controlled by cams 140, 141 are provided as described in Specification 544,684 for cutting out the motor when the antenna is fully extended or retarded. The circuits include a further switch 22 which when in the " out " position places the motor under the control of the cam-operated switches 83, 84 as described above and when in the " in " position makes a direet circuit for retracting the antenna, as when the aircraft is about to land. A lamp 23 controlled by a switch 185 associated with the landing gear is provided to give a warning when the antenna is not fully retracted at this time. Specification 546,460 also is referred to.

[Class 78 (iv).] Overload indicator mechanism of the kind which is operated by the pull on the luffing rope has the rope connected to a weight or spring-loaded lever system operating the indicator in which the leverage is varied by a cam and linkage in accordance with the maximum safe load at different radii. The pointer 1 works over an indicator quadrant 2 and is actuated by an arm 3 connected by a link 4 to a lever 5 working on a pivot 6 and provided with a weight 7 or spring. The end of the luffing rope 8 is connected to links 11 mounted on a pivot 12 on the lever 5. The weight 7 normally overcomes the pull of the luffing rope so that the pointer indicates a safe load. A link 13 is pivotally connected to the upper end of the links 11 and to a bent lever 14 mounted on a pivot 15 on the crane structure and having at its free end a roller engaging a cam 17 having an undulating contour. The cam is connected by an arm 19 and link 20 to the jib 9. The arrangement is such that variations in the inclination of the jib cause variations in the effective leverage of the pull on the lever 5 and corresponding indications of the pointer. In a modification a toggle linkage is arranged between the cam mechanism and the luffing rope linkage.
