[Class 144 (ii)] A wheel rim, of the kind described in Specifications 420,923 and 400,647, comprises an endless detachable side-flange 19 co-operating with a groove 14 in the rim-base 10, the flange having a region of locally-increased internal diameter adapted to span the wall 13 of the groove when the flange is deformed out of its normal plane, for which purpose a toolreceiving slot 24 is provided in the flange. In the construction shown, the region of increased diameter is provided by two diametricallyopposite recesses 22 in the flange. As shown in Fig. 3, wherein the flange 19 is in process of mounting or dismounting, that part of the lip 20 of the flange which is diametrically opposite the part which has been moved into the bottom of the groove overlaps the wall 13 by substantially half the full depth of the wall. According to the Specification as open to inspection under Sect. 91 the recesses may be provided in the rim-base wall 13. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 420,923.

Filed: 1969-09-12
Abstract: 1276350 Welding by fusion OSAKA TRANSFORMER CO Ltd 12 Sept 1969 [16 Sept 1968] 45055/69 Heading B3R [Also in Divisions G3 and H2] Arc welding apparatus of the short circuit metal transfer type is provided with a control system to stabilize the cyclical alternation of arcing and short-circuiting comprising a circuit 9 which detects the period starting with arc ignition and finishing with arc extinction, a circuit 10 having a pulse generator PG whose output is in series with a transistor Tr which is made conductive during the arc-on period detected by the circuit 9, and a control circuit 11 for the electrode feed motor 6a, which circuit receives constant frequency pulses from the circuit 10 to rotate the motor 6a at a speed directly proportional to the frequency during the arc-on periods. The circuit 9 includes Zener diodes ZD1, ZD2 of which the Zener voltage of the diode ZD 1 is selected to be higher than that of the diode ZD2 and lower than the arc voltage occurring during the arc-on period, whilst the Zener voltage of the diode ZD2 is selected to be higher than the voltage between the electrode and workpiece 2 during the short circuit period. The motor 6a may be a low inertia stepping type which makes a movement of one step per pulse and which is controlled so that the electrode feed speed is varied to stabilize the ratio of arc-on period to arc-on period plus short circuit period, Fig. 2 (not shown), which ratio has a value corresponding to the desired welding conditions. It is explained how, with a fixed feed speed, the melting energy P M  is dependent on six parameters of which the most important are the above-mentioned ratio and the equivalent resistance r e  of the electrode tip. Variations of r e  affect P M  and the ratio which in turn further affects P M , the relationship between the latter two parameters for a fixed feed speed being discussed, Figs. 5a-5c (not shown). The relationship between P M , the feed speed and the ratio as produced by the described embodiment is discussed, Fig. 5d (not shown), the effect of the invention being to control the feed speed in accordance with the melting rate, so that a variation of P M  caused by r e  produces a variation of the ratio and hence of the feed speed to restore the ratio and P M  to their original values.

Abstract: 1,091,390. Liquid filtering apparatus. M.E.L. EQUIPMENT CO. Ltd. Oct. 21, 1966 [Oct. 21, 1965], No. 47175/66. Heading B1D. In a liquid filter in which a moving band of filter medium 15, such as paper, felted viscose fibres or synthetic tissue, is entrained round an inward flow drum 1 in a tank 3 of liquid to be filtered, the band 15 is washed by water sprays 19 after leaving the tank and then wound on to a spool 23. In Fig. 3 the filter band extends between spools 14, 23 round drum 1, and its direction of travel is periodically reversed by transferring the drive from one spool to the other and reversing the drum rotation. Only the water spray 19, 19' on the take-up side of the drum are operative, their valve (24), and the spool drive clutch being controlled by a common mechanism. A signal may be given when the fabric on the supply roll nears its end and the motors automatically stopped. The drive speeds may be controlled by floatoperated means responding to the level in tank 3. Sprays 19 may be placed above the band rather than below, to wash it by reverse flow. In Figs. 1, 2 (not shown), the drum and filter band travel only in one direction, and when the supply spool 14 is exhausted it is replaced by a second spool, the ends of filter bands being temporarily joined until the leading end of the second band reaches the take-up spool. Since the filter bands are washed clean as they come off the drum 1, the apparatus can be operated with only two bands which are used alternately. The supply spool has a brake, and a pump delivers the washing water to the sprays. The drum 1 comprises coaxial perforate and imperforate walls 1b, 1a with the intervening space divided by axial partitions into chambers (5), each connected by a pipe 6 to a rotary distribution valve comprising two perforate plates (7, 9) which connect appropriate chambers to vacuum.

The preform may be injection moulded or formed by the preliminary blow-moulding of an extruded tube. As shown in Fig. 4, an extruded tube 15 is enclosed by preliminary blow-mould halves 19a, 19b, forming tail flash 31 which is removable by axially movable members 20a, 20b and blow-mandrel 22 is introduced, forming neck threads 12 by compression against the mould parts. Pin 24 is lowered to supply blowing air through duct 26 to blow-mould the parison into preform 32. Surplus interior material 30 is flattened by lowering of cap 25 on pin 24. Blowing air is then exhausted along groove 27 of pin 24, and port 28. Blow mandrel 22 is then replaced by final blow mandrel 36, Fig. 6, and the preform 32 transferred to the final blow-mould 40. The final blow-mould 40 comprises halves 40a, 40b, one of which 40a has a semicircular recess, the other 40b having a mating semicircular projection 53 having a circular cylindrical hole, across which is laterally movable a first, flat, bottom-defining member 43 and in which is a vertically movable, domed, second bottom-defining member 45. The mould halves 40a, 40b close on the preform 32, with first bottom member 43 in position. Pin 38 of mandrel 36 is then extended to stretch the preform until it contacts bottom-defining member 43 and the preform is blow-moulded to form a flat-bottomed article (Fig. 8, not shown). Bottom member 43 is removed and bottom member 45 moved up to deform the article bottom (Fig. 9, not shown). In the embodiment of Figs. 11-15 (not shown), cap (64) of blow mandrel (61) is extended, slightly stretching the preform, which is then blow-moulded. Bottom 43 is removed and member 45 extended, mechanically stretching the flat article bottom until it contacts the concave base (66) of cap (64) forming a sealed chamber, the bottom then being further deformed by air supplied through duct (59) of cap (45). Cooling may be effected by further blowing air or by cooled bottom parts 43 and/or 45. The blow mandrels may be rotated.
