Abstract: 949,811. Perforating; assembling force fits. BELLING & LEE Ltd. Dec. 28, 1962 [Dec. 29, 1961], No. 46589/61. Headings B3U and B3W. [Also in Division F2] In a method of securing an insert in sheet material a nonpointed spigot projecting from one face of a flange is used as a punch to make its own aperture in the sheet material, the said face of the flange being so formed and pressure being applied so that the said Face of the flange is staked to the face of the sheet material. The insert comprises a threaded spigot 1, a larger shank 2, which has a straight knurl 3 and is joined to the spigot by a chamfer 4, and a flange 5 which is undercut to form points 7, 8, 9 and 10. The insert and sheet material are placed between a die 12 and a ram 13. The spigot punches out a disc 14 and the shank 2 enlarges the aperture by punching out a washer 16. The hole in the washer is enlarged by the chamfer 4 so that the washer  falls off the spigot. Continued pressure forces the corners 7 . . . 10 into the sheet material 11.

They are then urged, by a gripper roller 31 above the conveyer, into a throat which opens into the side of a hopper 30 having walls spaced apart a distance substantially equal to the length of the articles S. A unit 110, by means of switches 108, 109 and a weightsensing plate 107, controls levels 112, 113, 114 to which the hopper 30 is filled.

Filed: 1966-11-28
Abstract: 1,176,152. Washing granular materials. WILKINSON RUBBER LINATEX Ltd. 23 Nov., 1967 [28 Nov., 1966; 27 Oct., 1967], Nos. 53176/66 and 48972/67. Heading B2H. A horizontal classifier for separating waterborne particulate material, e.g. mineral ore or sand, into different fractions comprises a closed launder to which the water-borne material is fed under pressure via an inlet section which diverges to the width of the launder in the direction of flow, and at least two receiving means for the reception of the different fractions of the material at least one of the receiving means being a hutch on the underside of the launder. In Fig. 1, a launder 17 is connected to a feed pipe 11 by means of a divergent inlet section 14, Fig. 2 (not shown). A valve-controlled clear water pipe 12 opens into the feed pipe 11. The underside of the launder is connected to hutches 20, 21 for the reception of respectively the heavy or coarse and light or fine particles. The hutches are connected to discharge pipes 24, 27, to the horizontal portions 24a, 27b of which are connected valve-controlled clear water pipes 25, 30. The portions 24a, 27b may be connected to hydrocyclones. An outlet section 31 converging to an outlet pipe 34 is connected to the launder 17. A pivotable vane 37 controlled by a wheel 38 is mounted near the mouth of the launder to direct a greater or lesser proportion of solids to the first hutch 20. Even distribution of material to the mouth of the launder may be ensured by vertical vanes (not shown) fixed to the floor of the inlet section 14 and by a cellular distributor preferably disposed at the mouth of the launder. In operation, a mixture of water and particulate material is pumped through the feed pipe 11 and is joined by clear water delivered through the pipe 12. The different fractions of the material are collected in the hutches. 20, 21 and dewatered in the hydrocyclones connected thereto. The slimes or very light or fine particles pass to waste through the section 31 and pipe 34. Alteration of the grading of the material may be effected by altering the output of the pump delivering the mixture; by controlling the flow of clean water through the pipe 12; and by controlling the flow of clean water through the pipes 25, 30, this latter measure having the effect of slowing down or accelerating the settling of the different fractions in the hutches 20, 21 thereby permitting more or less material being carried over in the water stream from the hutch 20 to the hutch 21 and from the latter to the section 31. In a modification, Fig. 4, a single hutch 45 is connected to the launder 41, the fine or light particles being discharged through an outlet section 44. The curved inlet section 43 is divided into upper and lower ducts 53, 54 through which are respectively pumped the water particulate material mixture and clear water.

Abstract: 1,116,964. Elastic wave transmission systems. WESTERN ELECTRIC CO. 18 Nov., 1965 [23 Nov., 1964], No. 48984/65. Heading H3U. An elastic wave transmission system includes a body of non-conducting gyromagnetic material and means for launching an elastic wave in the body in a first direction, the body being magnetized with a principal component of magnetization extending at an angle to the first direction, whereby the wave is propagated in the body in a second direction. As shown in Fig. 1, a body 10 of non-conductive ferromagnetic material having gyromagnetic properties is in the form of a rectangular plate 10 carrying on its lower face 11 a piezo-electric transducer 12. Suitable plate materials are yttrium iron garnet, lithium ferrite, europium iron garnet. A magnetic biasing field H variable in direction through an angle # is of such strength as to bias the plate material into the region of magneto-elastic interaction at the frequency of the signals applied to the transducer 12. In the absence of the biasing field the elastic waves travelling along the path 13 are reflected by upper face 14 and return to the transducer 12. However, a biasing field H2 at an angle # to the direction in which the elastic waves are launched by the transducer 12 causes them to be deflected along a path 15, the waves being reflected at the face 14 and returning along the same path. The amount of deflection of the waves is dependent upon the angle # and upon the strength of the biasing field. By increasing the deflection in Fig. 1, the length of path 15 is increased and hence the delay time between transmission and reception of a pulse at the transducer 12 is increased. In a modification (Fig. 5, not shown), the input from a transducer 42 is switched to a selected one of a member of output transducers 53 . . . 58 by varying the biasing field through positions H1 . . . H6. The underlying theory is described.

To contain the cushion in the air cushion vehicle mode a forward inflatable transverse diaphragm is provided to be extended against the resistance cables and air springs (Fig. 4, not shown) and an aft inflatable transverse barrier which is urged against cushion pressure by an inflatable chamber (Fig. 5, not shown).
