Title: Method and apparatus for applying a non-ferrous overlay on steel or steel alloy articles
IPC: B23K20/227
Filed: 1966-12-22
Abstract: 1,168,467. Making composite wire; drawing. TREFILERIES LEON BEKAERT P.V.B.A. 22 Dec., 1966 [23 Dec., 1965], No. 57480/66. Headings B3A and B3P. A method of applying a non-ferrous metal overlay to a steel or steel alloy wire comprises the steps of assembling a loose-fitting sleeve of the overlay metal to the wire, cold-drawing the assembly through a first die which reduces the diameter of the sleeve, so that it is a close-fit on the wire, through a stabilizing die, the length of which is at least ten times greater than its bore diameter and which prevents the sleeve being stripped off the wire when it passed through a final die which simultaneously reduces both the sleeve and the wire to form a molecular bond between them. In an apparatus for carrying out the method the wire (or rod) 11 and the sleeve 14 are passed through first and second dies 15 and 16 and forwarded by feed rollers 17 and 18 to a stabilizing die 21. This die is of considerable length in relation to its diameter and in an example has a bore of 5À6 mm. and a length of 70 mm. In this example a lead sheath is applied to a steel core. The assembly is drawn through the final die 22 by the rollers 23 and 24 in which a reduction of each of the components of the assembly occurs, the reductions being in proportion to their individual hardnesses.

Title: Multiplex communication system
IPC: H04M11/06
Filed: 1967-12-22
Abstract: 1,204,190. Multiplex pulse signalling. MAINICHI BROADCASTING SYSTEM and NIPPON ELECTRIC CO. Ltd. 22 Dec., 1967 [26 Dec., 1966], No. 58533/67. Heading H4L. Means are provided for transmitting a signal A, e.g. a facsimile signal, in repetitive gaps in a signal B, e.g. a television signal. As described, a facsimile signal in the form of a binary pulse train is transmitted during the vertical blanking intervals of a television signal, the pulses being positioned so that they avoid the blacker than black level and being such that they do not exceed the peak white level. The pulses of signal B are written into a store by a continuous pulse train and read out at a higher speed by pulse groups during the vertical blanking period, the converse occurring at the receiver. At the television transmitter the output of a facsimile transmitter 1 is detected at 2 and supplied to a twenty bit shift register 6 under the control of pulses from 7. The television signal is supplied via terminal 13 to a mixer 11, the vertical and horizontal sync. signals being selected at 12 and supplied to control the oscillator and frequency multipliers 3 and 5 respectively. Oscillator 3 produces an output frequency of 1200 c/s. in response to the input of 60 c/s. and oscillator 5 produces an output of 63 kc/s. with an input of 15À75 kc/s. The output of oscillator 5 is gated at 8, to produce a group of twenty pulses at an appropriate time within each vertical blanking interval, by a pulse from generator 4 controlled by the vertical sync. signal. These pulse groups together with the 1200 c/s. pulse train are supplied via the mixer 7 to the shift register 6, the facsimile signal being written in by the 1200 c/s. pulse train and read out by the pulse groups. The output of the register is supplied via a pulse shaper 10 controlled by the pulses from gate 8, to a mixer 11 where it is combined with the television signal. Similar equipment is provided at the receiver for extracting the facsimile signal. In a modification, instead of the presence or absence of pulses representing the facsimile signal, two different pulse durations are used so that the timing information for the pulse groups is contained in the groups, thus enabling the pulse generator 4, oscillator 5 and gate 8 to be dispensed with at the receiver. In a further arrangement a group of reference pulses may precede or follow the group of pulses carrying the facsimile signal.

Abstract: 1452630 Space heating or cooling units MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 28 Dec 1973 [28 Dec 1972 14 May 1973 18 Oct 1973] 60030/73 Heading F4V [Also in Division F1] A cross-flow blower is characterized in that a vortex stabilising plate 2 and back guide wall 3 are provided in the vicinity of the outer periphery of a cross-flow impeller 1 to form air suction B and air delivery C on rotation of the fan in direction A, and on the air suction side is arranged a flow dividing guide wall 4 for dividing out air flow D. The flow dividing guide wall 4 may be made rotatable about a pivot 13 and operated manually via a bowden cable and lever (22, 14, Fig. 2 not shown). The effect of such rotation may be seen in Figs. 5-7. In Fig. 5 the guider 4 closes off the passage 24 so that air flow E through a heat exchanger 10 passes to delivery port 9b. With the guide wall 4 in the position shown in Fig. 6 air flow G is present in the passage 24 and passes either on the back side of the guide wall as in flow H or joins the main flow F and passes through outlet 9b. In Fig. 7 some of the air flow I is exhausted to the passage 24 as flow J and some is expelled through the outlet 9b. If the space between the tip 26 of the guide wall 4 and the vortex stabilizing plate 2 is made smaller all of the flow I passes through the passage 24 as flow J and in addition air sucked in as flow K also passes through the passage 24. To reduce the noise generated by the blower a bend in the tip 26 is provided having appropriate dimensions (Fig. 8, not shown), and a nose 27 is provided with an inclined surface 27a. The guide wall 4 may be of an axial length h which is substantially less than the length of the cross flow fan (Figs. 2 and 11, not shown). The specification sets out preferable dimensions for the various parts. The heat exchanger 10 may be used to heat or cool the ventilation air.

At the end of the stroke, the worm movements are reversed, so that the continuous rotation of worm-wheel 5 is obtained, the first worm being now rotated whilst the second worm is subjected to the hydraulic pressure to perform a driving stroke. The drive may be automatically controlled, the rotated idling worm being timed to complete its stroke before the pressure actuated working worm to effect a continuous operation and the pressure changeover at port A via a snap-action valve or an automatic electric solenoid operated valve triggered by a double acting micro-switch 16 operated by the lost motion stop rod 17 at the end of each worm stroke. In Figs. 3 and 4 (not shown) a rod (21) is continuously moved linearly by two screw/pistons (19,20) functioning in a similar fashion to the first embodiment. The irreversible locking action of the worms and worm-wheel of the first embodiment and of the screwed-pistons on the linearly movable shaft of the second embodiment enable a load to be held when the power is shut off. To reverse the drive the continuous pressure supply to and exhaust from the ports B and C are simply interchanged.

Title: Template for tile fitting
IPC: G01B5/20
Filed: 1979-06-12
Abstract: The invention relates to an apparatus for use in determining the shape of a tile for fitting into a restricted space on a fixture. A locating bar 26 on a housing member 10 projects downwardly therefrom to be locatable against an edge of a tile and a pair of elongate members 20 register any spacing from full tile size to zero between the locating bar and locations on a fixture perimeter. Each of the elongate members is movable along its longitudinal axis relative to the housing member and can be retained in any desired position. With one face of the locating bar against an edge of an installed tile the spacing is registered and is then transferred to a tile to be cut with the opposite face of the locating bar engaging against the edge of that tile. The desired spacing between tiles is automatically achieved by virtue of the thickness of the locating bar, and each side edge of the housing member has a scale of measurement. In another embodiment, Fig. 28 (not shown) only a single elongate member (104) is provided but a bar (116) which may be pliable is provided at its end to mould to the contour of the tile. In Fig. 40 (not shown) the housing member is telescopic. <IMAGE>
