Abstract: 1281078 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 5 Sept 1969 [6 Sept 1968] 44052/69 Heading A3B A method of bonding an outsole 16 provided with a web of thermoplastic adhesive composition to the bottom of a lasted shoe upper 20 includes the steps of locating the outsole 16 in its correct position on the shoe bottom, separating the outsole and the shoe bottom, heating the adhesive, outsole 16 and shoe bottom, returning the outsole 16 to its original position and finally applying pressure to bond the outsole 16 to the lasted upper 20. The lasted upper 20 is supported by a last pin 26 and toe rest 28 on a plate 30 which is mounted on a ram 22. The outsole 16 which is provided with adhesive is then placed manually on the lasted upper 20 in its correct position. Suction cups 36, which are connected to a vacuum source are then lowered to grip the outsole and are then raised to separate the outside from the shoe bottom. An infra-red heating plate 38 is then moved between the outsole and shoe bottom to activate the adhesive and heat the outsole and shoe bottom. The plate 38 is then retracted and the suction cups 36 are lowered to return the outsole to the shoe bottom. Pressure member 40 which is connected to the piston rod 43 of cylinder 39 then applies light pressure and is retracted. The shoe support is then moved sideways to a position below a press pad 44 and the ram 22 is actuated to bond the outsole to the shoe bottom. The adhesive is preferably a polyester in the form of a web of randomly disposed filaments as described in Specification 1259661.

[Also in Division H1] Thermal matrix head.-A thermal printing head comprises an array or matrix of selectively energizable, heatable printing elements, wherein each element 10 includes a heating member and an isolation element (e.g. a diode) made up of semi-conductor materials on an electrically insulating substrate 15. A layer of semiconductor material 9, such as a single crystal silicon of N-type conductivity, is deposited by standard epitaxial deposition techniques on to the substrate 15, which is a single crystal sapphire. An aluminium layer 14 is secured to the substrate to conduct away heat. The layer 9 is then selectively etched off the substrate 15 to form a matrix of isolated rectangular islands (16, Figs. 4 to 6). The islands (16) are then delineated and etched, and diffused P-type regions 17 and 18, Figs. 3 and (4) are formed therein. The islands (16) are then again delineated and etched, and a diffused N+-type region 19 is formed therein. The silicon dioxide layer 20, which was formed during and after each of the prior diffusion steps, is etched away to form holes 21 to 24 therein, through which first level conductors 25 to 30 make ohmic contact with the underlying semi-conductor material. The P-type region 17 constitutes the resistive heating element (11, Fig. 2) of the matrix, while the P-type region 18 opens the anode of the isolating diode (12, Fig. 2) and N + -type region 19 forms the ohmic contact region for the diode cathode. A dielectric insulating layer of glass 45 is deposited over the first level conductors 25 to 30 and insulates them from second level conductors 31 (33 and 34, Fig. 6). A beryllium oxide (BeO) or aluminium oxide (Al 2 O 3 ) overcoat 51 which has a high thermal conductivity and high electrical resistivity is formed on the face of the type matrix. The first level conductor 25 extends across a plurality of printing elements 10 (Fig. 6) and makes ohmic contact at 21 with the anode of the diode of each element 10. Conductor 26 in each element 10 interconnects the cathode of the diode with heating member 17. Conductor 27 in each printing element 10 internconnects the heating element 17 with one of the selection conductors 28, 29 or 30 via a respective second level conductor 31 (33 or 34, Fig. 6).

In a preferred embodiment the rhombus is scanned in one direction only, i.e. clockwise, and sense is indicated by the rhombus either starting or finishing at a determined point, i.e. at corner one; the sense is representative of an increase or decrease in the signal period with respect to a reference. In an embodiment described, a complete rhombus = 20% distortion, greater values than this being indicated by further rhombi or parts thereof having displaced origins. A high stability oscillator 1 of frequency 1000 times telegraphic speed of period L directly provides a distortion signal H1 of period 0À1% of period L, and dividers 2 and 4, 5 each divide by 10 providing a signal h2 which is applied to a JK flip-flop 7 which provides a reference signal V. Second JK flip-flop 8 receives h2 and V and provides a square wave in quadrature with V which is applied to an integrator amplifier 9 providing a signal X in the form of a periodic sawtooth wave. Signals U from JK 8 is applied to the input of a second integrator amplifier 10 providing a periodic sawtooth wave Y in phase quadrature with X. Signals XY are applied to X, Y planes of a C.R.T. which traces a rhombic polygon whose axes are vertical and horizontal respectively. A circuit L3 includes a modulo 5 counter 31 receiving V signals and A reset signals, the counter output being decoded to define ranges of plus or minus 0-20 and 21-40% distortion, the latter arranged being indicated by a second rhombic figure having a displaced origin, such displacement being initiated by outputs on appropriate ones of lines p-t.

The resulting aqueous liquor after filtration was extracted with a 1 : 1 vol./vol. mixture of butanol and isoaryl alcohol containing HCl. The solvent extract was purified by contact with a solution of HCl and H 3 PO 4  and then a solution of dioctyl pyrophosphate in dodecane was used to extract the uranium. Example 3 specifies the use of monododecyl phosphate in dodecane as uranium solvent.
