Title: Coupling for coaxial cables
IPC: H01R9/05
Filed: 1959-02-12
Abstract: 863,753. Two-part couplings. SEALECTRO CORPORATION. Feb. 12, 1959 [Feb. 12, 1958], No. 4884/59. Class 38 (1). In a two-part coupling for a coaxial cable a metallic sleeve is positioned between the outer conductor and inner insulation thereof, the outer components of the cable in the region of the metallic sleeve are enclosed by a resiliently deformable sleeve and a two-part tubular assembly accommodates and exerts a compressive force on the deformable sleeve so that the outer conductor and metallic sleeve are forced into firm contact. As shown, a two-part coupling for connecting two coaxial cables, one with an inner axial conductor 11 and the other with an inner axial conductor 65, comprises a male tubular assembly 15, 16, secured to a female assembly by means of a threaded coupling sleeve 72, the conductor 11 being soldered to a contact member 31, 32, 33, 34 received by a contact member 60, 62, 64 soldered to the conductor 65. A coaxial cable 10 comprising the axial conductor 11, inner insulation 12, an outer coaxial conductor 13 which may be of woven or braided copper wire, and external insulation 14 is received by a longitudinal bore 17 in the sleeve 15 which screws into the sleeve 16 and forms an annular recess to accommodate a deformable sleeve 50 and metal end washers 51, 52 enclosing the cable insulation 14 in the region of a metallic sleeve 44 fitted between the outer conductor 13 and the inner insulation 12. The terminal portion 43 of conductor 13 is flared outwardly at right-angles and contacts a flange 45 on the sleeve 44. Relative rotation of the sleeves 15, 16 causes the washers 51, 52 to compress the sleeve 50 and thereby force the conductor 13. and metallic sleeve 44,into firm contact. The contact means for the outer conductor in the female connector assembly may be the same as that in the male connector assembly.

Title: Telephone-actuated control system
IPC: H04M11/00
Filed: 1961-04-27
Abstract: 995,731. Sub-station equipment. S. W. KWAN. July 27, 1962 [April 27, 1961], No. 4942/61. Heading H4K. A telephone - actuated control system includes an electrical actuator for operating the cradle switch of a telephone and a time switch to permit the actuator to be energized only at selected times. As shown, telephone set 15 is mounted in a base 14 which includes a sound absorbing device 10 which damps the sound of the telephone bell except when coil 1 is energized by a time switch 8 provided with adjustable contacts 2, 3, 4. Handset 26 rests on a support 27 and the cradle switch 21 is normally depressed by spring loaded arm 22. In operation power unit 91 and damping unit 10 are energized at preselected times by switch 8. If a call is received during one of the energized periods the sound of the bell is picked up by tuned microphone 52, the signal is amplified and rectified by amplifier 45 and operates relays 44 and 47. This energizer relay 32 which lifts arm 22 operating cradle switch 21 and closing a holding circuit over normally closed contacts 35 and three-minute thermal time delay 49. Power is also supplied to transistor amplifier 41 and intercom set 51. If the caller now transmits a selected tone, by means of a tuning fork or transistorized oscillator, the signal is passed to loud-speaker 42 by microphone 28 and amplifier 41 and is picked up by tuned microphone 52 and passed to frequency selective amplifier 65 and tuned reed relay 66. If the tone corresponds to the resonant frequency at reed 67 relay 75 is energized closing contacts 78 which energize relay 81, which is held open for thirty seconds by holding contacts 82 and thermal time delay 79. Contacts 83 energize solenoid 84 which operates press-to-talk button 85 on intercom set 51. The caller may then speak, the loud-speaker 86 placed near intercom set 51 being connected to signal amplifier 41. After thirty seconds button 85 is released and the caller can listen to the intercom. The other reeds 68, 69, 70 may be used to operate a tape recorder, wireless set or electric cooker (not shown). If a call is received when the system is not energized the sound of the bell is damped and thus does not cause a disturbance. If handset 26 is lifted contacts 31 open, preventing relay 36 from being energized and closing contacts 30 to energize amplifier 41 and intercom set 51 and to operate relay 32 to operate cradle switch 21. The telephone may now be used in the normal way and when the handset is replaced on support 27 contacts 30 open and de-energize relay 32 allowing spring 34 to pull down arm 22 restoring cradle switch 21. Contacts 31 also close and energize delayed closing relay 36. This delay prevents relay 32 from being permanently energized through its holding circuit.

Filed: 1946-02-18
Abstract: 617,898. Artificial eyes. KINGSTON, A. Feb. 18, 1946, No. 5075. [Class 81 (ii)] [Also in Group V] Artificial eyes are made in plastic by first moulding a concave-convex body 32 with a recess 34 in the convex surface thereof, inserting an iris disc 36 and a corneal button 37 in the recess and subjecting the whole assembly to combined heat and pressure to marry the parts together. The iris disc may be made, e.g. of paper, celluloid or gelatine and the iris image produced photographically or otherwise. The iris may be coated on both sides with transparent plastic bonding material having the characteristics, e.g., refractive index of the sclera and the corneal button. If material of different refractive index, e.g., gelatine is used, surface reflections may be avoided by placing very thin mesh Japanese rice paper between iris and corneal button. Thin transparent foil, e.g., of polystyrene or silk tissue paper between iris and corneal button. Thin transparent foil, e.g., of polystyrene or silk tissue paper may be placed between the iris and corneal button to display the iris image, and between the iris and the sclera, e.g., to modify the iris colour. The corneal button preferably has a bevelled periphery which co-operates with a thin annular parapet 35 formed around the recess 34 of the sclera or with a separate transparent plastic ring of wedge section, during the marrying process, to produce a limbus effect. The sclera portion 32 preferably has a peripheral flange 33, which provides a reserve of material, and may be veined with an engraving tool, stained with water or spirit stain, and the channels closed by the marrying process. The plastic, e.g., polystyrene or the material sold as " Perspex " or " Kallodent " (Registered Trade Marks) may be formed into a tablet or medallion blank by cutting from a sheet or by injection moulding and the tablet formed into the recessed hemispherical sclera by projection moulding or by heat and pressure between closed dies. Apparatus suitable for moulding the sclera portion and marrying the eye assembly is described (see Group V). Specification 590,930 is referred to.
