Abstract: 621,995. Lasting. ROTARY MACHINE CO. March 3, 1947, No. 6027. Convention date, Oct. 12, 1946. [Class 17 (i)] [Also in Group XV] In a machine for folding and securing by cement the binding of an insole, or for lasting an upper, the work is fed by hand with the binding or upper margin gripped between a heated finger which softens the adhesive on the margin and a rotating wheel which folds the margin over and presses it down upon the insole. The folding wheel 11 is rotated by a motor 4 and has screw-thread-like grooves 41 on its edge and a bevelled face 39. The finger 26, which is electrically heated, is carried by a rotatable rod 23 and is urged into engagement with the face 39 of the wheel by a spring 36, to an extent controlled by a stop screw 37. In use, the finger is swung away from the wheel by means of a hand lever 33, an insole A is held with its edge engaging a guide roll 18, and the margin C of the binding tape is threaded between the finger and the wheel. When the adhesive on the margin has been softened by the heated finger, the latter is released to grip the margin against the bevelled face of the wheel. Rotation of the wheel then stretches the margin and presses it down on-the upper surface of the insole. In a modified form, the folding wheel has a second bevelled portion stepped from the first in place of the screw thread.

Patent GB-1211677-A (GB)
Title: Television camera
IPC: H04N9/09
Filed: 1969-02-05
Abstract: 1,211,677. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 Feb., 1969 [8 Feb., 1968], No. 6169/69. Heading H4F. To reduce persistence effects due for example to rapid variations in the scene when a sharp video signal rich in detail is produced the camera comprises first and second camera tubes in which the effective capacitance formed by the target plate of the first tube is large relative to that of the target plate of the second tube, the target plates being scanned by electron beams to produce video signals, and from the video output of the first tube only an aperture compensation signal is produced which is added to the video output of the second tube. Such a camera provides a satisfactory display for monochrome X-ray television in which quicklychanging phenomena must be observed in detail. A colour television camera according to the invention, Fig. 1, comprises camera tubes 1, 2, 3 producing signals #G, #R and B and a camera tube 4 the target plate (conductive signal plate and a photo-conductive layer) of which has larger effective capacitance than the target plates of tubes 1, 2, 3, e.g. larger area or reduced thickness of the photoconductive layer, producing a luminance signal Y containing more picture detail than the signals #G, #R and #B. The dashes above the symbols G, R and B indicate that the maximum frequency occurring in these signals is smaller than that in the luminance signal Y. Means 13 derives an aperture compensation signal C from the signal Y which is superimposed on each amplified colour signal G, R and B in adders 14 1 , 14 2  and 14 3 , the colour signals being gamma corrected before superposition or as shown after superposition of aperture compensation signal C. Means 13 may comprise two delay lines each having a delay of a fraction of one line period, a horizontal aperture compensation signal being obtained by subtracting from the once delayed signal Y half the sum of the undelayed signal Y and the signal Y delayed twice. A vertical aperture compensation signal may be obtained in this manner, the two delay lines having delays of at least one line period. The signal Y is preferably frequency modulated on a carrier before being applied to the latter delay lines and subsequently demodulated. Alternatively, means 13 may comprise one or more memory tubes. In a second embodiment, Fig. 2 (not shown), the four identical camera tubes produce signals Y, Y, R and B, and signals #Y+C, #R-Y+C and #B-Y+C are produced after superposition of signal C, the effective capacitance of the target plates of the tubes producing signals #Y, #R and B being reduced by including in the path of the light from the scene on to the target plates means for concentrating the light in a discontinuous manner, e.g. a glass fibre device which divides the light into strips, which strips may be divided into dots. The three colour signals G, R and B may be derived from one tube having vertical indexing strips, the green, red and blue light being successively projected between the indexing strips.

Filed: 1970-02-10
Abstract: 1291378 Resolving electrical signals into components COMPAGNIE DES COMPTEURS 10 Feb 1970 [18 Feb 1969] 6318/70 Heading G1U In a method of specifying a first vector relative to the direction of a second vector, a first alternating electrical signal representing the first vector by its phase and amplitude, and a second alternating electrical signal representing the second vector by its phase, are produced, and these signals are combined in order to produce one or more signals related at least to the phase difference between the two signals. As described the first signal Vcos (wt + α), Fig. 3 is produced by a flowmeter 10 via a 90 degree phase shifter 12 and a summing circuit 11, and represents the magnitude and direction of flow of the sea with respect to axes fixed in a ship. The second signal Ucos (wt + #) is produced by two magnetometers 20, the D.C. outputs Ux, Uy of which are chopped 15, 15A by quadrature clock pulses, summed 17, and filtered 18, and represents the direction of magnetic north with respect to the same axes. The second signal Ucos (wt + #), and a 90 degree phase shifted 19 signal derived from it are squared 21, 21A and the quadrature signals resulting control gates 22, 22A respectively, to which the first signal Vcos (wt + α) is also applied, to produce, via smoothing circuits 23, 23A, D.C. signals representing the magnitudes of the inphase and quadrature components of the first signal with respect to the second signal, which components represent the components of the flow with respect to magnetic north. In a modification Fig.4 (not shown), D.C. signals representing the magnitude of the first signal and of the phase difference between it and the second signal are produced.
