Patent GB-1292609-A (GB)
Title: Improvements in or relating to methods of making insulated tinsel conductors and cords
Inventor: COCCO EUGENE RAYMOND
IPC: H01B13/008
Filed: 1969-12-10
Abstract: 1292609 Flexible insulated conductor WESTERN ELECTRIC CO Inc 10 Dec 1969 [27 Dec 1968] 60267/69 Heading H1A A conductor 2, Fig. 2 (not shown), comprises tinsel ribbons wound on a cotton strand or polymer monofilament, the winding being in the form of single or double lay helices with butting or overlapping edges, or more than one helix per lay, a typical ribbon being À020 inches wide and À001 inches thick. A polymer tube 8 is extruded on to the conductor 2, by a tubing mill 5, with a clearance between the conductor and the tube, and after passing through cooler 9, the insulated conductor passes through a heat chamber 13 where it is heated to about 320‹ F., followed by a cooling trough 14 which cools the insulated conductor to 100‹ F. Capstan 12 is driven faster than capstan 10, so that the insulated conductor is stretched by up to 10%, preferably from 4 to 5%, causing the tube 8 to become stress oriented, increasing its tensile modulus and reducing the clearance to À001 inches. It is stated that such a treatment makes it possible for the polymer to recover an original helical set after extensions up to several times its original length. The insulator material may be a polyamide, polypropylene or polyethylene. The chamber 13 may be heated by gas, superheated steam, or an inductive heating coil. An outer jacket (16), Fig. 2, (not shown), may be applied over a number of the above conductors, and by winding such a cord on a mandrel, heating it to about 320‹ F. for about 9 minutes to heat set it, and subsequently reversing the direction of the helix a retractile cord may be made, see Fig. 3 (not shown).

Title: Improved optical system for line follower head
Inventor: DIPROSE KENNETH VICTOR
IPC: G06K11/02
Filed: 1968-12-19
Abstract: 1,260,314. Line followers. HANCOCK & CO. (ENGS) Ltd. Nov. 7, 1969 [Dec.19, 1968], No. 60454/68. Heading G1A. In an optical system for a line follower head, light from a source passes through a first polarizing filter, through a semi-reflecting surface and through a beam deflection system (which effects a scan of a substrate bearing a line to be followed), and diffused light (scattered by the substrate) reflected back through the deflection system is reflected by the semi-reflecting surface and passes through a second polarizing filter on its way to a photo-cell. The polarizing filters plane polarize the light and are set in quadrature so that light reflected by lens in the system or by the substrate without scattering cannot reach the detector. The signal to noise ratio is thus increased. Two embodiments are described. In one (not shown) the semi-reflecting surface is a half silvered mirror and the filters are located between the half silvered mirror and a lamp and a silicon photo-cell respectively. As shown the filters and semi-reflecting surface are combined in the form of a Nicol prism 49.

Abstract: 1299730 Radio navigation LTV ELECTRO-SYSTEMS Inc 23 Dec 1969 [23 Dec 1968] 62753/69 Heading H4D In a low-frequency radio navigation system accuracy of a position fix may be in error due to propagation anomalies. According to the invent ion the transmission time of each received signal with respect to a local time reference is determined and the determined transmission times are combined in a formula which incorporates relative weighting. The embodiment relates to a very-low-frequency system known as "Omega", and the transmission time T 0  of a composite signal is given by: where T 1  and T 2  are the transmission times of the lower-frequency f 1  and higher-frequency f 2  Omega signals respectively. In particular : Receiver, Figs. 6, 7.-Incoming 10À2 kHz and 13À6 kHz waves are mixed with respective harmonics of a local, accurate, oscillator 16, Fig. 6, and outputs taken to phase detectors 8, 14. The outputs of the phase detectors and an amplifier 28 are taken to a computer 29 which pairs each of the signals from each transmitting station and processes them to derive signals each having a magnitude representative of the distance to a respective transmitting station. A suitable electro-mechanical computer, Fig. 7, utilizes a signal from filter 32 (Fig. 6) for motor excitation amplifier 36 and for commutator 42 (Fig. 6) which supplies energization to amplifiers 44, 46; for each transmitting station A, B, C, D a separate motor-phase-shifter unit is provided, A and A<SP>1</SP>, B and B<SP>1</SP> &c., Fig. 6, corresponding to received signals on 10À2 kHz and 13À6 kHz, respectively. To obtain the transmission time for the composite signal a differential gear 82 is included. Shaft 102 of indicator 68 indicates the composite signal travel time based on station A; a shaft 112 indicates the phase difference between the 10À2 kHz signals from stations A, B, and further shafts as depicted. If three or more frequencies are transmitted from each station an average derived from them may be employed to further increase accuracy.
