Abstract: 1480157 Heat-setting polyester film E I DU PONT DE NEMOURS & CO 4 Aug 1975 [5 Aug 1974] 32514/75 Heading B5B An asymmetrically, biaxially orientated polyethylene terephthalate film is heat set in three stages. The temperature in the first stage is from 150‹ to 250‹ C., in the second stage at least 5‹ C. below the first stage temperature but above the second order transition temperature of the film and in the third stage from 125‹ to 190‹ C. The heat-set film is quenched after the third stage. Preferred features are that the biaxial stretching is produced by firstly stretching longitudinally by up to twice its length, secondly stretching laterally from 3 to 4À5 times its width and thirdly stretching longitudinally again to 4À3 to 4À7 times its length. The film may also be longitudinally stretched by from 0À5 to 6À5% after the second heat-setting stage. The film may be allowed to release during the first setting and after the third.

Title: An indicator of musical intervals applicable for selecting and combining colours

Filed: 1921-12-05
Abstract: 191,574. Florence, M. S. Dec. 5, 1921. Harmony charts; transposing-scales. -For the purpose of selecting and combining colours harmoniously an indicator comprising a dial, divided according to the intervals of a chromatic musical scale, is used in conjunction with a series of indicating plates, the divisions of the dial being coloured with colours in the order in which they occur in the ordinary spectrum. Fig. 1 indicates the manner in which the dial is divided and Fig. 2 shows the use of a selecting plate for the selection of three colours in harmonic relation. The plate in this case is triangular and corresponds with a major triad in music. For a selection in accordance with a minor triad the plate is reversed. Several examples of plates corresponding with various chords in music are described, that shown in Fig. 10 being a dominant seventh. Tn a modification a cylinder is substituted for the dial and encircling rings for the plates.

Title: Electronic servo apparatus
IPC: G06V30/144
Filed: 1964-08-11
Abstract: 1,008,560. Automatic character reader. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 29, 1963], No. 32655/64. Addition to 996,509. Heading G4R. In the character reader of the parent Specification the flying spot of the scanner is controlled to follow the contour of the character in a series of part-circles. A generator 200-202 produces two signals of sinusoidal waveform, 90 degrees phase displaced, and integrators 204, 206 receive the sine wave signals either directly or attenuated at 203, 205 (depending upon whether the scan produces a white or black signal) and produce control potentials. Signals are derived from these to represent X and Y co-ordinates of the centre of the part-circles as they move round the character. According to this invention the extreme values of the Y signal, representing the height of the character, are used to control the radius, of the partcircles of the scanner to make the size of the scan circles proportional to the character height so that the resolution is the same for characters of all sizes. The output of oscillator 200 is phase-shifted at 201, 202 to produce sine and cosine waves. These pass via attenuators 203, 205 to the integrators. When photo-cell 214 receives a black signal the attenuators are enabled so that a small search circle is described on the black and a large circle on the white, the scan thereby stepping round the outside of the character. Filters 246, 247 pass only the slowly varying component of the signal, i.e. the X and Y values representing the moving centre of the circle. The curve follower performs a first pass round the character, the maximum excursions at terminal 247a being stored to obtain a measure of the character height. The positive and negative Y voltages are stored on capacitors by opening gates to charge them from a source of current whenever the stored voltage is exceeded by the control voltage from 247. The outputs are applied to a difference amplifier which governs the amplitude of the signal produced by the oscillator 200 so that on passes after the first the scanning circle is proportioned to the height of the character.

Title: Circuitry for generating the logical inverse of binary signals
IPC: H03K21/00
Filed: 1955-11-16
Abstract: 783,041. Ferro-resonant circuits. NATIONAL CASH REGISTER CO. Nov. 16, 1955 [Dec. 14, 1954], No. 32742/55. Class 40 (4). In a non-linear circuit controlled by a twolevel D.C. signal 9, the capacitive element C1 of series ferro-resonant circuit L1, Cl which is energized by an A.C. supply 1 is shunted by a parallel ferro-resonant circuit L2, C2 and a condenser C3, the inductors L1, L2 being saturable. An application to signal invention is described with reference to Fig. 1. In the case of a lowlevel D.C. signal in winding 4 of inductor L2, the parallel ferro-resonant circuit L2, C2 is in resonance and the high impedance of the shunt circuit establishes a highly conductive state in the series ferro-resonant circuit L1, C1. A high output potential is thus obtained at terminal 6 and is available on an output lead 8 after rectification and smoothing by components 3 and R<SP>1</SP>, C4 respectively. Saturation of L2 by a highlevel D.C. signal disables the parallel resonance condition of L2, C2, and it is arranged so that consequential series resonance of L2 and C3 takes place. Due to the reduced impedance condition of the shunt circuit, the ferroresonant circuit L1, C1 passes into an offresonance low conductive state and a low output potential is obtained from terminal 6. Clamping diodes D1, D2 may be used to restrict the output voltage between the limits e1 and e2. The arrangement may be applied to comparison of two-level potentials at terminals 10, 11, Fig. 3, which act in opposed windings 12, 13 on inductor L2. In this arrangement a high output potential at terminal 6 is obtained only if the potentials at 10 and 11 have the same high or low value. A suggested application is the indication of errors between binary signals produced by two identical circuits which are simultaneously computing the same problem.

Filed: 1935-11-30
Abstract: 465,149. Four-stroke engines. ALSTON, C. H. T. Nov. 30, 1935, No. 33232. [Classes 7 (ii) and 7 (vi)] In a cylinder having one or more common air-inlet and exhaust ports 22, controlled by the piston and by a rotary valve 23, a further scavenging air charge is admitted during the exhaust period to prevent trapping of exhaust gas in the cylinder, and to enable the ports 22 to be low in the cylinder wall and thus well shielded by the piston during the period of high temperature and pressure ; e.g. the ports should not be uncovered by the piston until it has performed between 40 and 50 per cent of its stroke. The scavenging air may be admitted by ports 27 controlled by the piston and opened at the end of its stroke, or by ports at substantially the same height as the ports 22 and valve-controlled. At the end of the admission stroke, the ports 27 supply a supercharge, which may be at a higher pressure than the scavenging charge, the two charges being supplied by a rotary valve 30 ; the part 29 is connected to a rotating-vane pump provided with a throttle valve, and the annular part 31 is connected to atmosphere, or another pump, or a different part of the same pump. As shown the two charges are compressed by the underside of the piston 14, but they may be delivered to the cylinder direct. The supercharge may be delivered by the valve 23 through the port 22 by an additional pump to that supplying the ports 27 or by the same pump, the ports 27 being then controlled by a rotary valve and only opened during the exhaust period. In an in-line engine the valves extend along the line of cylinders and may be chain driven.
