Title: Improvements in or relating to wave traps
IPC: H01Q9/30
Filed: 1960-02-04
Abstract: 878,961. Aerials. TELEFUNKEN G.m.b.H. Feb. 4, 1960 [April 21, 1959], No. 4004/60. Class 40(7) [Also in Group XL(b)] A quarter-wave coaxial-line wave trap comprises an inner conductor 1 and a number of outer conductors 7 having one end short-circuited to, and fixed in position on a circle coaxial with, the inner conductor, the outer conductors being bent back into the space between the inner conductor and the outer portions of the outer conductors. The inner conductor 1 forms a support for a rod aerial 3 and is connected to the outer conductors 7 by a shorting plate 6. The plate 6 forms part of a conical container 2 for a box 4 enclosing an aerial matching circuit. A coaxial line 5 leads from the box 4 along the outside of or, as shown, through the interior of the supporting mast 1. The outer conductors are covered in plastic material and are supported by an insulating ring 8 and an insulating disc 9. The inner portions lie on a conical surface whereby the capacitance of the line increases from the vicinity of the bends to the inner ends of the conductors. The variation .in both inductance and capacitance along the length of the line results in an improved band-width.

Filed: 1957-02-13
Abstract: Textile materials consisting of rayon, i.e. regenerated cellulose of either the viscose or cuprammonium type or cellulose esters, e.g. cellulose acetate, are de-oiled and desized by passing them, preferably in open width, through one or more baths of a solvent, namely trichloroethylene or perchloroethylene, preferably at elevated temperature, eliminating solvent entrained in the materials by subsequently passing them through an aqueous medium maintained at an elevated temperature sufficient to flash off the solvent, then passing the materials through an aqueous alkaline solution of a peroxygen compound at a pH of at least 11, and subsequently steaming to promote desizing.  The solvent treatment is preferably carried out for 10 seconds to 5 minutes at 80 DEG -87 DEG C. in the case of trichloroethylene and at 110 DEG -120 DEG C. in the case of perchloroethylene.  The aqueous flashoff bath is maintained at a temperature of at least 73 DEG C. in the case of trichloroethylene and at least 86 DEG C. in the case of perchloroethylene and in either case preferably at 90 DEG -95 DEG C., the time of contact being 8-60 seconds.  Suitable peroxygen compounds are sodium peroxide, sodium percarbonate and hydrogen peroxide, alkaline peroxide solutions of pH 11 to 12 having an available oxygen content equal to that of a solution containing 3 to 15 grammes per litre of sodium peroxide being preferred.  The peroxide solution preferably contains a stabiliser, e.g. an alkali-metal silicate, and an anionic or non-ionic wetting agent.

Abstract: 418,433. Prepayment mechanism for meters. ALDER & MACKAY, Ltd., and ANDERSON, J., Stewart Terrace, Edinburgh. Feb. 17, 1933, No. 4983. [Class 27.] In prepayment mechanism for gas meters and the like operable at will by either of two classes of coin, e.g. pennies and shillings, the coins are inserted through a slot 9, Fig. 2, to a coin carrier c, the base of the coin pocket being formed by a plate m slidable against the.action of a spring k. The plate m is depressed to different extents by a penny and a shilling and carries a projection g which engages tail-pieces r, s, Fig. 3, on two levers t, u pivoted at w on an axis parallel to the axis on which the coin pocket rotates. Where a shilling is used, the projection g engages the tail a and swings the lever u to cause a tooth y thereon to engage a quantity wheel 1. In the case of a penny being inserted, the projection g engages the tail r and causes a tooth x on the lever t to engage a quantity wheel z, the movement of the tail r being limited by two stops r<1>, r<2>. The quantity wheel z drives a measuring-out mechanism 2 directly through a free wheel mechanism comprising a pawl and ratchet device 3, while the wheel 1 transmits its movement through a train of gearing 4 and a second free wheel device 5 giving a 12 : 1 increase. If a halfpenny be inserted, the projection g passes the tail s but does not move far enough to engage the tail r. The quantity wheels 1, z and coin pocket mechanism are disposed in a casing 6 closed at front by a price-change plate d, the gearing 4 and measuring-out mechanism 2 being disposed outside this casing.
