Patent GB-1063981-A (GB)
Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/04
Filed: 1962-11-20
Abstract: <PICT:1063981/C1/1> In a method of manufacturing flat glass using the "float" technique a buoyant body of molten glass is formed by permitting the glass to flow laterally unhindered to its limit of free flow, this buoyant body in ribbon form being advanced along the molten metal bath by means of a controlled tractive effort, the viscosity of the advancing ribbon being controlled within the range 103 to 107 poises, and the control of the tractive effort being so inter-related that when the ribbon has reached its desired thickness its viscosity is such as to prevent any further dimensional change. A layer 50 of molten glass is established upon a bath 7 of molten tin (or tin alloy) at the limit of its free flow and passed through a narrow inlet 18, below an adjustable end wall 13, into the main bath. The roof structure covering the bath has a recessed portion 44 part way along its length which contains adjustable radiant heaters. Temperature regulators ar also included in the bath of molten metal at 42, in the headspace above the bath at 43, and include a heater 49 just inside the headspace from wall 13 and a cooler 47 just prior to the recessed portion.  The layer 50 is advanced down the bath as a ribbon 24 by means of traction rollers 25,26 in the annealing lehr 38.  The viscosity of the glass is closely controlled within the range 103 to 107 poises by suitably controlling all the heaters and coolers, and is especially controlled by the heaters 46 in the recessed headspace 44.  By closely linking the rate of pull on the ribbon 24 out of the bath with the viscosity gradient along the length of the advancing ribbon the width and thickness of the ribbon can be well controlled, and easily varied. The ribbon is sufficiently cool before leaving the bath so as not to undergo further dimensional changes nor be damaged by the rollers.  The headspace contains a gas inert to the molten metal.

Title: Radar system
IPC: G01S13/52
Filed: 1961-02-09
Abstract: 962,440. Radar. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Feb. 9, 1961 [Feb. 12, 1960], No. 4906/61, Heading H4D. Relates to a pulse radar for suppressing echoes from stationary objects in which signals of two different frequencies F -f and F+f are transmitted simultaneously and are each received in individual channels where they are converted to signals of frequency f, the outputs from the two channels being combined, e.g. in a synchronous detector, to give a phase-sensitive output which is applied directly and through a delay device 37 to a subtraction arrangement 33 to suppress echoes from fixed objects. According to the present invention the necessity for rigid stabilization of the transmitted frequencies in such a system is avoided by including in at least one receiving channel a further frequency converter to which is fed a local signal of frequency f1. A shown, the transmitted frequencies F -f and F+f are produced by mixing a frequency F from an oscillator 2 with a frequency f produced in a frequency multiplier 23 from a subharmonic input f/n from an oscillator 24. The corresponding echo signals in the receiving channels 25 and 26 are each converted to frequency f by mixing with the frequency F and are then mixed in frequency changers 27 and 28 respectively with frequencies f2 and f1 derived from the subharmonic f/n by frequency multipliers 31 and 32 to give equal frequency outputs f-f2 and f 1 - f (i.e. f-f2 = f1-f, f1+f2=2f) which are applied to a synchronous detector 21 coupled to the cancellation circuit 22; alternatively, the frequencies f1 and f2 may be such that f1 - f2 = 2f, the equal output frequencies from channels 52 and 26 then being f+f2 and f1-f. In a modification, Fig. 3 (not shown), the frequency change 27 is omitted and the output frequencies f and f1-f from the channels 25 and 26 are applied to a mixer whose output is applied to the cancellation circuit 22. In another modification. Fig. 4 (not shown), the frequency changer 27 is omitted in channel 25 and in channel 26 the output f1-f from the frequency changer 28 is mixed in a further frequency changer with the frequency f2 to give an output f.

Title: Timepiece
IPC: G04B19/25
Filed: 1972-02-02
Abstract: 1360543 Watches EBAUCHES SA 2 Feb 1972 [8 Feb 1971] 5004/72 Heading G3T A timepiece comprises a stem 17 having an inner position in which rotation of the stem moves a selector ring 30 to select one of mechanisms 26-29, and an outer position in which the selected mechanism may be actuated e.g. to set a calendar or hands. As shown the mechanisms 26-29 respectively control a date ring 4, a day ring 2, conventional hands 9, 10, and an additional universal hour hand 8. In the inner stem position, a pinion 32 attached to the stem meshes with a toothing (31), Fig. 4, (not shown), on the selector ring 30 whereby the latter may be rotated until one of notches 33-36 in the ring is positioned opposite the selected mechanism and a corresponding one of function indicators 37 is visible through a dial window 38. Each mechanism 26-29 comprises a lever carrying a wheel; a nose on the selected lever thus enters the notch to bring the wheel into mesh with an operating ring 24. If the stem is then pulled out, a pinion 18 slides on the stem to engage a wheel 23 which meshes with the ring 24 so that rotation of the stem then actuates the selected mechanism. When the stem is pushed in once more, a return ring 58 ensures that all the mechanisms 26-29 return to their rest positions, out of engagement with the ring 24. An alternative arrangement is envisaged in which the selector ring 30 has a single notch. The stem may have a further winding function if the timepiece is spring driven. The stem may also have an innermost position to which it may be depressed against a return spring to control a chronograph hand. The additional hour hand 8 is mounted on a cannon 11 which fixedly carries a ratchet wheel 13 which is engaged by a pawl 14 pivoted on hour wheel 12 so that wheels 12, 11a revolve together in one direction.

Colour kinematography; optical systems.-In colour kinematography two pictures are simultaneously produced in the same plane and within a normal film space, but arranged diagonally, C1, C2, Fig. 3. To avoid parallax the pictures are taken by means of a single lens through colour filters, the rays being divided by a prism system so as to produce the pictures in the position shown. The rays passing through the lens L are partially reflected at the surface PS of the rhomboidal prism U1, the reflected portion being again reflected from the opposite face of the prism to the film P1 through a filter F1 and the parallel plate U4. The rays transmitted by the surface PS pass through the prism U2, filter F2 and are twice, reflected by the prism U3 to produce the image C2. To produce the images in the same plane the optical lengths of fhe light path may be corrected by selection of the thickness of the parallel plate U4 and also by making the prism U1 of a glass having a higher refractive index than that of the prism U3. Oblique rays of light may be prevented from reaching the sensitive surface without reflection by increasing the distance between the reflecting surfaces of the rhomboidal prisms, any surplus areas of the entrance and emergent faces being rendered opaque.
