Abstract: 968,414. Welding by pressure. G. H. PETERSON. Oct. 2, 1961, No. 35546/61. Heading B3R. In heating opposed metal portions and welding opposed surfaces thereof together, a first high-frequency current from a first source is caused to flow along one of the portions, a second high-frequency current from a second source of current is caused to flow in another of the portions in immediate spaced proximity with respect to the first current, the phase relationship of the currents is maintained to produce proximity effect for localized heating and the surfaces are butted together. A pipe blank 11, Fig. 1, is passed through squeeze rolls 12-15 which bring together the edges 17, 18 for welding at point 19, the edges being heated by applying contacts 21, 22 to the opposite edges and a contact 23 to the pipe beyond the point 19 and supplying a high-frequency current between the electrodes 21 and 23, 180 degrees out of phase with a similar high-frequency current supplied between electrodes 22 and 23. D.C. supply leads 26 are connected to a pair of high-frequency generators 27, 28 of the same e.g. 10-500 kc. per sec. or higher frequency output with a phase controller 33 between them. Two spaced strips 37, 38, Fig. 2, are heated by a supply as above described but with separated contacts at both ends of the strips and when heated the strips are butted to weld them. The electrode 23 in Fig. 1 may be supplied from one terminal of a high-frequency generator and the electrodes 21, 22 are supplied, one directly from the other terminal and the other through a phase shifter, or alternatively the high-frequency generator may be connected to a transformer, the centre tapping of the secondary being connected to the contact 23 and the ends of the secondary being connected to the contacts 21, 22. Three strips may be arranged side-by-side, currents in phase being supplied to the outer pair and current 180 degrees out of phase being supplied to the centre strip, the heated strips being butted to weld them. A strip may be welded on edge to a plate by passing currents at 180 degrees phase differences along them, two such strips, separate or forming the legs of a channel member may be welded simultaneously to a plate by supplying in phase currents to the strips and 180 degrees out-of-phase current to the plate and three strips 81, 82, 83, Fig. 9, arranged at 120 degrees spacing are welded by supplying currents to them 120 degrees out-ofphase. The phase difference although 180 degrees may be merely greater than 0 degree. Specifications 772,279 and 851,528 are referred to.

Abstract: 1,001,658. Aerials. SIEMENS & HALSKE A.G., and STEFFENS & NOLLE A.G. Sept. 10, 1963 [Sept. 11, 1962; Feb. 1, 1963], No 35641/63. Heading H4A. The azimuthal direction of an aerial comprising a wide-band primary element 4 of basket construction and one or more reflectors 1, Fig. 1, which may be constituted by sub-divisions 2, 3, vertically hinged together) is varied by rotating the reflectors around the primary element on a railway track 5. The reflector is mounted on three wheels 6, 7, 8, and those lying towards the extremities of the reflector 6, 8 are slidably mounted so that the angle subtended by the reflector, and hence the shape of the radiation pattern, may be varied. The reflector is constituted of a tubular base 20, Fig. 2, into which vertical rods 21 are inserted to form a comb-like structure. The lengths of the rods may be unequal so that a repetitive pattern of rods is formed in which, if there are n groups of different lengths the ratio of the lengths of the longest to shortest rods is as the nth root of the quotient of the upper and lower frequencies of the frequency band of operation. The reflector may alternatively be formed of mesh or conductive cables, and may be curved. The primary radiator 4 is formed of rods arranged on the surfaces of two opposing cores. The wide band properties of this are stated to be such that five to one frequency band may be employed and it is further stated that at the higher frequencies in this band the radiation is predominantly from the lower portion of the aerial. The reflector may have its lower portion shaped, Fig. 3 (not shown), to be parallel to or be on a cone from an apex common with that of the lower portion of the aerial or a plurality of reflectors 44, 45, 46, Fig. 5, may be employed so that the distance of the reflecting surface from the primary element decreases with increasing frequency. In other embodiments a series of circular railway tracks may be used, Fig. 7 (not shown), or a spiral track, Fig. 6 (not shown), so that the distance of a single reflector may be physically varied. A director element may be moved with the reflector or reflectors.

Abstract: 400,454. Teetotums. FERON, E. E. P. and LOSSOW, C. V. (trading as SOC. FERON ET LOSSOW), 1, Rue Commines, Paris. Dec. 30, 1932, No. 36888. Convention date, June 22. [Class 132 (ii).] A teetotum especially for playing poker and poker dice, has one part fixed to an axle and one or more parts of different axial length but of the same cross-section loosely rotatable on the axle. An axle 4 with milled head 7 for spinning has a screwed connection with a balanced hexagonal part 1 bearing card values, as shown in Fig. 3, on its sides 1a, the part 1 being provided at the centre of its base with a small point 2 acting as a pivot. A balanced part 8 of hexagonal form but smaller in height than part 1, having poker hands, as shown in Fig. 4, marked on its sides 8a and having a shoulder 8b, is loosely rotatable on a shoulder 5 on the axle 4 between a collar 6 on the axle and the upper plane surface 3 of the part 1. The restricted contact area between the parts 1, 8 lessens the frictional force to relative motion between them. The axle 4 may be made to extend right through the part 1, the end of the axle forming the pivot. The axle 4 and part 1 may be made integral, the part 8 being placed on axle 4 above part 1 and being secured against falling off by means of a removable pin or collar screwed into or on the axle 4. A third part may be loosely rotatable on the axle 4 and may bear designations such as " spades," " hearts," " diamonds," " clubs and "joker." The device can be of any dimensions and can be of metal, ivory, bone, casein product, or wood. According to the Specification as open to inspection under Sect. 91 the device may be made of galalith. This subject-matter does not appear in the Specification as accepted.

Abstract: 1450977 Towel dispensers NEUCO APPABATEBAU AG 23 Aug 1974 [29 Oct 1973 37044/74 Heading B8M In a fabric hand towel dispenser comprising a housing with means for holding fresh and used towel reels and a smoothing stripper member for deflecting and consequently tensioning and smoothing used towel on its passage into the housing to be taken-up on an electric motor driven reel, the member is movably mounted and engaged by pretensioning means which yieldably urge it into an operative position between two projections but, when the tension in the towel exceeds a predetermined value, allows the member to be forced from its operative position and thereby operate a switch to stop the motor. In the dispenser shown in Fig. 1, fresh towel 5 from reel 4 is supplied by roll 6 driven by electric motor 8. Used towel returning to be wound on roll 11 by roller 12 driven from electric motor 13 is deflected, by a limb 16a of a spring-loaded pivotal flap 16, into the space between projections 17, 18, (bounded in depth by a wall with forward projections at the lateral ends of the stripper member): when the tension in the towel overcomes the bias of a spring 21, e.g. if the towel is held by a user against the wind-up or when the towel tightens on the underside of the dispenser, the flap 16 rotates and arm 19 operates a stopswitch 23 for motor 13. Passage of the end of the towel is also monitored by a pivotal detector finger acting independently of, and protruding through a cut-out portion in, flap 16 and its hollow pivot shaft, Fig. 4 (not shown), to rotate an arm 20 which also operates switch 23 or a separate stop-switch (not shown). When, as in some types of dispenser, motor 13 is reversed to dispense a limited quantity of used towel, the flap 16 is held in a position clear of projections 17, 18, by the left-hand end of a shift bar 29 which is operated to engage arm 19 by a dog or cam 30 rotated by a drive geared to roller 6 and is latched and then restored by pawls 31 and 36 geared to roller 12. In the dispenser of Fig. 5, fresh towel delivery is effected by pulling it, whereupon a lever arm 43 with pressure roller 42 is first pivoted to the position shown against the bias of a spring 45 and arm 46 is held for a predetermined period by a suction cup 44. The movement of an arm 47 rotates another lever pivoted at 49 so that draw member 52 attached to arm 50 pulls a spring-loaded switching arm 54 connected to a smoothing stripper flap 53 which is thus withdrawn from projections 17, 18. The turning of the dispensing roller 41 caused by pulling the towel is also transmitted (by gears 58, 59, and chain 61 co-operating with wheels 60, 62) to and turns a draw-in roller 57 in the unwinding direction. When the predetermined interval has expired, suction-cup 44 releases arm 46 so that spring 45 reverses the previous pivotal movements, gear 59 disengages from gear 58, flap 53 returns to operative position and electric motor 64 drives roller 57 in normal winding direction, subject to operation of a stop switch 67 by arm 66.
