Title: Improvements in or relating to glass fiber light-transmitting devices
Inventor: HICKS JOHN WILBUR
IPC: G02B6/08
Filed: 1965-05-04
Abstract: <PICT:1062835/C1/1> <PICT:1062835/C1/2> <PICT:1062835/C1/3> A glass fibre light-transmitting device comprises one or more long and slender fibres 16, Figs. 5 and 7, or 41, Fig. 9, each having a core 18 or 411 of glass of relatively high refractive index surrounded by a coating 19 or 42 of glass of lower refractive index, the device having a cross-sectional configuration of a re-entering polygon formed by a pair of spaced, oppositely disposed, substantially plane parallel sides joined by a pair of re-entrant V-shaped sides disposed with lines of their respective apices extending between the first sides in a plane parallel thereto.  The single fibre 16 may be formed by dipping a circular core rod into the coating glass to give an all-over coating, the coated rod then being passed through a heating coil to driven rollers 22, Fig. 5, with V-shaped ridges 31, 32 to form a butterfly shape.  The rollers 22 are mounted on blocks 25, 26 for movement towards and away from each other and are heated as by coils 33, 34.  A plurality of the fibres 16 may then be packed together as in Fig. 7 in a metal, ceramic or carbonaceous support 35 heated by a coil 37, the rods 16 being pressed down by a cover 38 and the assembly fused together.  The fused assembly may then be reheated and passed between rollers similar to rollers 22, these steps being repeated as required to form multifibres of the required fineness. With extremely fine multifibres, there may be flexibility of the fibre and this feature may be utilized in aligning the bunched ends of a plurality of multifibres with elements of an associated optical apparatus or in slowly heating a group of multifibres to allow them to be simultaneously shaped or curved intermediate their ends.  For light transmitting devices of large area, groups of multifibres may be secured together at one or both ends or throughout by cement or by fusion, the end surfaces being optically finished as by grinding, polishing or immersion in a liquid of like refractive index.  As shown in Fig. 9, a multifibre device of the butterfly shape is formed from a plurality of initially round rods 41 packed with a support 43 having a recess 44 which, with a shaped plunger 49, is of butterfly shape, the support 43 and plunger 49 being heated by coils 53-56. The heat and controlled pressure from plunger 49 causes the rods 41 to coalesce and the coatings 42 to fuse together, the resulting butterfly-shaped structure being drawn down to fibre size by gravity or rollers as with fibres 16.

Abstract: 949,857. Boring earth. HUGHES TOOL CO. May 25, 1961 [Jan. 3, 1961], No. 18978/61. Heading E1F. [Also in Division F2] An earth boring rotary drill bit, Fig. 1, comprises a conical cutter 7 rotatably mounted by means of ball and roller bearings 8, 9 on a pin 6 integral with a leg 4 of the bit head 2. The balls 9 are loaded in their raceway througha bore 11 which is plugged at 15 after insertion of the balls. Lubricant for the bearings is supplied from a reservoir 17 which communicates with the bore 11 by means of a passage 18. The lower end of the reservoir 17 is provided with a collapsible rubber diaphragm 20 which serves to transmit pressure from the drilling fluid to the lubricant 16. The upper end of the reservoir is closed by a cap 21 through which lubricant is introduced after removal of a plug 23. Sealing of the bearings is effected by an axially resilient seal ring 31, Fig. 2, which is a force fit on the pin 6 and which is compressed between annular faces 36, 37 respectively on the cutter 7 and the leg 4. The ring is provided with axial protuberances 34, 35, the area of contact of the protuberance 34 with the face 37 being greater than that of the protuberance 35 with the face 36 so that the area of the end face of the ring exposed to lubricant pressure is greater than that exposed to drilling fluid pressure. The difference in these areas helps to maintain sealing contact when the drilling fluid pressure exceeds the lubricant pressure which fluctuates as a result of axial and wobbling movements of the cutter in operation. A gap 29 between the ring 31 and the wall 45 of a counterforce in the cutter 7 permits radial movement of the cutter in operation.

Abstract: 740,411. Protective cut-out arrangements. SIEMENS - SCHUCKERTWERKE AKT.- GES. July 9, 1953 [July 9, 1952], No. 19072/53. Class 38(5) In a control and protective arrangement, e.g. for use with mining installations, D.C. sources 5, 6 having voltages of different magnitudes are connected in opposition at the ends of a pilot conductor 8 and an earth conductor E, a polarized relay 4 being connected in series with the pilot conductor adjacent the lower voltage source 5 and control switches 10a, 10e being associated with the higher voltage source. In Fig. 1, on the depression of the "on switch" 10e, current flows from the higher voltage source 6 through the relay 4 which closes contacts 12 to effect the closing of a circuitbreaker 2. A relay 14 is now energized and closes contacts 13 to maintain the pilot circuit closed when the switch 10e is released. In the event of a short-circuit between the conductors 8, E, current flows from the source 5 in the reverse direction through the relay 4 and fault path 7 and the relay 4 closes contacts 11 to effect the opening of the circuit-breaker 2. The D.C. sources may be batteries as shown, but rectifier arrangements may be used, Fig. 2 (not shown). Alternatively, charged condensers may be used as the higher voltage source, the condensers being initially charged from the low voltage source and subsequently maintained charged by a rectifier arrangement supplied from the power conductors, Figs. 3 and 4 (not shown). The higher voltage source may only be connected to the conductor 8 during the actual closing operation of the circuit-breaker 2. In this case, the relay 4 controls the circuit-breaker through a relay which completes a holding circuit for itself when energized, Fig. 6 (not shown). When the supply is from a transformer having its star point connected through a resistor to the conductor E, the relay 4 may be arranged to produce tripping on fault between a main conductor and the conductor E, a by-pass circuit for the alternating current being provided, Fig. 5 (not shown).
