Title: Method and apparatus for testing a liquid having a cloud point due to the appearance in the liquid or crystals having an anisotropic nature
IPC: G01N25/02
Filed: 1965-09-27
Abstract: 1, 113, 293. Determining cloud point of oils. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 27, 1965 [Sept. 28, 1964], No.41086/65. Headings G1A and G1D. In an arrangement for testing a liquid having a cloud point i. e. a point when, during cooling of the liquid, crystals of anisotropic structure appear, a cooling sample is illuminated with polarized light, the temperature is measured, and it is observed, preferably by photo-electric means, whether or not the sample has caused depolarization, the polarized light being obstructed by for example a cross-polarized plate when the liquid does not contain crystals and the presence of crystals resulting in an increase of observed light. Light from a lamp 2 Fig. 1 passing through a slit 3 is plane polarized by a material 4 before being applied to the sample and an analyzing filter 5 plane polarized at right angles to polarizer 4 obstructs the passage of polarized light to detector 6. A test cell may comprise a pair of plates of transparent medium between which the liquid is made to flow, the plates having channels through which coolant such as alcohol or propane may be passed and being coated on their non light transmitting surfaces by an opaque material. The lightbeam may include a red filter whereby visible components of the polarizing filter are suppressed. Flow of the sample liquid through the cell may be controlled by the detector output, the arrival at cloud point operating a relay to flush out the cell. The detector output may be used to control a refrigerator in order to hold a continuously flowing sample at cloud point. In a further system the detector of a reference cell which may contain the cooled sampled rewarmed, may be arranged in a bridge with the test cell detector to control Peltier elements in the refrigerator.

Filed: 1967-09-21
Abstract: 1,207,172. Selective printing. ANKERWERKE A.G. 21 Sept., 1967 [2 Dec., 1966], No. 42923/67. Heading B6F. [Also in Division B8] A voucher is fed to a printing position in a book-keeping machine by feeding the voucher past the printing position and reversing the direction of feed, the voucher engaging a front stop defining the printing position. The voucher is inserted in a funnel 12 between an upper plate 1 and lower plates 2, 3, and is detected by feelers 25a, 26a which are linked to stops (31, 33), Figs. 1, 4 (not shown), permitting the voucher to continue only if it is sufficiently wide to actuate both feelers. The voucher is driven by a roller 15 co-operating with an oblique pressure roller 20 which urges the voucher toward a side guide (4, Fig. 1). The drive is taken up by rollers 15a, 15b and 15c to drive the voucher to the back of the apparatus where it trips a feeler 145 and abuts a back stop (5, Fig. 1). The rollers 15-15c are driven by a motor 40 through friction clutches (Fig. 6, not shown). The drive to the rollers 15-15c is reversed and the voucher is driven to the printing position between type wheels 9 and an impression hammer 11, where it is stopped by a front stop 136 reciprocated vertically by a cam 83, driven by the printing machine drive through a shaft 85. The voucher is held in place by a button 111 actuated by a cam 82. After a printing operation, the button 111 and stop 136 are retracted and the voucher is driven to a delivery shoot 63, deflected by a flap 98 operated by a cam (81), Fig. 2 (not shown). Further cams operate a detector 126 which locks the printing mechanism if the voucher is too short, and the drive reversal mechanism. The feeler 145 trips a switch 144 for initiating the drive to the shaft 85, and a lever 108, which operates the button 111, also actuates a switch 78 which controls the motor 40. On absence of a voucher at the printing station, the button 111 overtravels and causes printing to be prevented.

Abstract: 1284867 Winding and transferring stator coils ESSEX INTERNATIONAL Inc 8 Sept 1970 [18 Sept 1969] 42938/70 Heading B3A Apparatus for winding stator coils and transferring the wound coils to a transfer device or slotted tube 88 which has spaced, parallel blade elements defining slots therebetween, at least two of the slots receiving opposite sides of a wound coil, comprises at least one coil form 24, 26 having portions on which are formed the opposite sides of the coil, the portions having recesses 178, 180 for receiving at least a part of the two-blade elements with the coil received in slots defined by the two blade elements and the blade elements adjacent thereto. The coil forms each comprise a fixed part 94 and a part 96 mounted on a support assembly 38 for pivotal movement so as to collapse the coil forms. The coils are wound by a flyer 28, with the coil form horizontal and the part 96 in its expanded position. When the coils have been wound, a piston-rod 86 raises a clevis 78, which in turn raises a push-rod 68, thereby pivoting the coil form to its downward position 24a. A gear 40 is indexed to bring the next coil form to the winding station, where it is pivoted horizontal by the clevis 78 acting on a push-rod 66. When all coils have been wound, a fluid power cylinder 54 is actuated to move the apparatus along rails 48 into alignment with the coil insertion apparatus 30. The tube 88 is then lowered by a fluid power cylinder 92, the blade elements thereof passing through the recesses 178, 180, until the distal ends of the blades project beyond the coil forms to be in overlapping relationship with blades 44 of the apparatus 30, as at 88a. As the tube descends, it trips latch mechanisms thereby releasing members 136 to collapse the coil forms. The coils are transferred manually to the blades 44. The coil forms are expanded during the next winding cycle as they are pivoted horizontal at the winding station. A stripping member formed with blades 248 may be provided, see Fig. 8, which transfers the coils from the tube 88 to the apparatus 30. The stripping member is driven by the piston-rod 246 of a power cylinder mounted on top of the cylinder 92, the rod 246 extending through the rod 90 and cylinder 92. A further modification comprises replacing the tube 88 by a hand held tube 288, see Fig. 10. This tube is inserted upwardly into the recesses 178, 180 and when the distal ends 202 of blade elements 196 engage projections 304 on levers 294, the latch mechanisms are tripping to collapse the coil forms 24, 26.

Abstract: 1409799 Band limited transmission system KOKUSAI DENSHIN DENWA KK 21 Sept 1972 [23 Sept 1971 25 Oct 1971] 43686/72 Heading H4R In a quality improving system for a bandlimited voice signal, a received band limited signal is branched at a hybrid 4 (Fig. 1) and one of the branched signals is applied to an arrangement of an instantaneous compressor 7 and frequency expander 8 arranged in cascade and forming a higher harmonic signal generator, the output e3(t) of which is applied to a band pass filter passing the higher harmonics, which higher harmonics are then combined with the amplified other branched signal. Such an arrangement is designed to increase the band width from 0À3 to 1À5 kHz to 0À3 to 3.4 kHz. Figs. 2 and 3 show respectively examples of an instantaneous compressor having a compression ratio of ¢ and an expander having a square expansion coefficient and which also full wave rectifies the waveform, thereby introducing the higher harmonics. This is also described in the Specification the application of the arrangement of Fig. 1 to a radio telephone receiver, to radio terminal equipment of the dincompex type, and to a telecommunication system in which a telephone signal and a " stroke signal "as transmitted in respective halves of the frequency band, (Figs. 5-8, not shown). Fig. 9 and Figs. 10-12 (not shown) illustrate a more complicated frequency expander for use in place of the arrangement of Fig. 3. The output of the instantaneous compressor 102(7) is used to phase modulate a signal of frequency #0 in phase modulator 103 which includes an oscillator of frequency #0. The output e3(t) of the phase modulator is applied to a frequency converter 104 which also has as an input an unmodulated signal e6(t) of frequency #0 provided by a synchronous oscillator 106 driven by a signal derived by a band pass filter 105 from the signal e3(t). The output of the frequency converter is passed through a low pass filter 107 to supply an output signal comprising higher harmonics of the input signal at terminal 101, the harmonics being either even or odd (but not both). If both odd and even harmonics are required a second frequency converter and low pass filter are supplied in parallel with converter 104 and filter 107, the synchronous oscillator 106 supplying the signal e6(t) to the second frequency converter via a 90-degree phase shifter (Fig. 10, not shown). The band pass filter and synchronous oscillator may be replaced by a single oscillator of frequency #0 which drives both the phase modulator 103 and the frequency converters (Figs. 11 and 12, not shown). Fig. 13 shows an arrangement where one of the branched signals is further branched into a number of frequency bands and a higher harmonic generator is applied for each frequency band. The higher harmonics produced for each frequency band are then weighted before being combined. The Specification contains a mathematical analysis of the operation of the circuits.
