Abstract: 1,225,309. Attaching electrical components to circuit boards; assembling force fits. AMP. Inc. 4 Dec., 1968 [21 Dec., 1967], No. 57473/68. Headings B3A and B3U. [Also in Divisions B8 and H2] Terminals T to be inserted into apertures 12 in an insulating panel 10 are forced into a flexible resilient tape 16 to extend from one side thereof substantially at right-angles to the plane of the tape and in a predetermined pattern. The tape with its attached terminals may be helically wound on a storage spool (R, Figs. 15, 16, not shown). A severed length of the tape is then positioned with its terminals T in alignment with guiding mouths 24 of apertures in a tool 20, which may be of nylon or harder material, the apertures in the tool corresponding to those in the panel 10. The tool is then positioned over the panel and moved towards it so that the ends 14a of the terminals enter the panel apertures 12 and portions 14b wedge therein. After soldering of the terminals to the panel, the tape 16 is peeled away, the presence of tool 20 preventing displacement of the terminal. In a second embodiment, Fig. 5, the tool 28 employed comprises two parts hinged together at 34, the parts having at their edges remote from the hinge V-shaped recesses 30c into which the ends 14<SP>1</SP>a of the terminals are pressed, the tape being received in recesses 30a. After the ends 14<SP>1</SP>a have entered the panel apertures the tool 28 is removed and the terminals driven into the apertures by a block (36, Fig. 9, not shown). In a third embodiment, Fig. 10, a tool 40 is provided, the tool comprising upper and lower blocks 42, 48, which are slidable relatively to each other by bundles 44, 50. The apertures in these plates are connected to the edges of the blocks by openings 48a which are relatively staggered when the terminals on the tape 16 are applied to the tool. After entry of the terminals into the panel apertures the handles 44, 50 are moved towards each other to align the slots and allow the tool to be withdrawn laterally from the inserted terminals.

Abstract: 1,226,103. Weft replenishing mechanism. ASSOCIATED PERFORATORS & WEAVERS Ltd. 22 April, 1968, No. 19111/67. Heading DIE. In a wire weaving loom a spent bobbin 4 is removed from the shuttle 1 and transported to a rewinding station, a new bobbin is inserted in the shuttle, the old and new weft trails are knotted together outside the shuttle and the knot is pulled through the shuttle before picking recommences. In Fig. 1 a clamp 39 clamps the old weft trail extending to the fabric, a member (not shown) places the weft around fingers 31 which are rotated to draw off weft around fingers 31 which are rotated to draw off weft from the old bobbin, a bobbin remover 8 descends and a lever 10 is pivoted to engage a bar 28 on the shuttle, the shuttle is moved axially to free the bobbin, the bobbin remover 8 rises taking with it the bobbin and then rotates to deposit the bobbin between a chuck 44 and a centre 16 of a rewinding station. The removing of the shuttle places the old weft trail through a knotting device 18 and the fingers 31 are again rotated to strip the trail from the bobbin and leave its end just above the knotter 18. The remover 8 then rotates to engage the new bobbin which is then lowered into the shuttle. Loading the new bobbin into the shuttle causes the new weft trail to pass between clamps and shears 26, 27 into the knotter 18 which is operated to knot together the old and new trails. The new trail is then severed by the shears 27 and is then correctly located for rewinding of the spent bobbin which, after rewinding, is moved by the remover 8 from the rewinding station to the full bobbin station. The knot is pulled through the shuttle, before picking, by further rotation of the fingers 31.

In a beverage dispenser, water at 15 passes solenoid valve 16, pump 18 and flow heater 19 to emerge over shelf 36 in mixing chamber 22 with dispensing outlet 37, where it mixes with dry powder stored in chamber 24, agitated by rotary vanes 30 geared by teeth 32 to an auger 25 which forces powder towards outlet 35, entering the mixing chamber and falling on shelf 36. Handle 23 actuates the auger via clutch 26. In order to prevent steam from the mixing chamber affecting the dry powder, a chimney 50 is placed over the top of the mixing chamber so that an air inlet 51 is formed and the powder outlet leads laterally into the chimney. A low wattage heater 56 attached to a sloping side of the chimney allows the radiant heat to warm the dry parts of the dispenser and induce a draft of vapour from the mixing chamber and air at 51 up the chimney and out of vents 43, thus keeping the powder outlet 35 dry. A lamp 58 inside the chimney may replace heater 56 and radiate directly on the outlet. The chimney, auger tube, mixing chamber and powder container 24 may be of transparent plastics and may be illuminated.

In a drum brake of the type comprising a pair of brake shoes 18, 20, slidably mounted on a fixed support, and in which an actuating device 22 or 24 mounted on the fixed support between at least one of the pairs of adjacent shoe ends includes an actuating member 36 extending into the housing of the device and a piston or tappet 26 slidable in a bore of the housing and extending between the actuating member 36 and one end of the adjacent shoe, the piston includes a first element 64 operably connected to the actuating member and a second element 86 operably connected to the shoe, abutment means (e.g. pin 108) carried by one of the elements (e.g. 64) being engageable by positioning means (e.g. diametral surface 102) on the other element (e.g. 86) for correct relative positioning of the elements. Where a piston or tappet has a groove 72 at one end for engagement by rollers 54 associated with wedge 38, and a slot 84 at the other end for engagement by the end of a brake shoe 18, and where the actuating mechanism as a whole is orientated at a small angle to the axis AA, Fig. 2, of the wheel axle (not shown), the piston, which has a lug 76 to engage a groove 80 in the housing 22, normally has to be shaped to correspond to the brake housing on either the left-hand side of the vehicle or the right-hand side, respectively. The invention provides for the piston to be made in two parts or elements, one part 64 having the actuator-engaging groove 72 and the other part 86 having the shoe-engaging slot 84, part 64 having the abutment pin 108 and part 86 having the stepped end surface 100, 98, 102 engageable with it, so that the two parts may be mutually rotated to either one of two limiting positions, and the composite piston may thereafter be inserted into the housing so that the groove 72 and slot 84 are respectively correctly aligned. Thus a single design of composite piston may be used for brakes on both sides of the vehicle. The other piston 28, Fig. 3, in housing 22, incorporates a conventional slack-adjusting mechanism 30 and thus comprises two parts which are mutually rotatable in any event.

Abstract: 1301461 Wet separation of granular materials WINTERSHALL AG 5 Jan 1970 495/70 Heading B2H In a process for separating granular materials by froth flotation a fine-grain (0.06-1mm.) loading agent is added to the flotation medium to increase its apparent specific gravity whereby the proportion of the coarse-grain (1 mm. or over) fraction of the material separated in the froth is increased. Salts and insoluble substances, e.g. ferrosilicon or magnetite, may be used as loading agents with flotation in salt liquor, and insoluble substances may be used with flotation in water. Alternatively, the. residue from a previous flotation may be used. In one example, coarse-grain (1-4 mm.) sylvite (KC1) is separated from mineral rock salt (NaCI) by flotation from a saturated NaCl/KCl solution containing fuel oil, a frothing agent, a collector consisting of alkylamine hydrochloride and a fine-grain (0.06-1.0 mm.) loading agent having a specific gravity of 1.6 g/cc. In another example, in a NaCl/KCl separation by flotation of NaCI with condensation products of fatty acid and urea, fine-grain kieserite is used as a loading agent to cause coarse-grain NaCl to float. Kieserite in a saturated salt solution may be floated by the addition of NaCI and kieserite in water by an insoluble loading agent. The loading agent may be recovered from the frothed concentrate or from the residue by screening, sifting, magnetic, electrical or electrostatic separation, by further flotation or by dissolving in water.
