Filed: 1972-06-28
Abstract: 1356088 Regenerated cellulose films LA CELLOPHANE 28 June 1972 [29 June 1971] 30291/72 Heading B5B Unitary regenerated cellulose films made by the viscose process comprise a core derived from one viscose, a homogeneous and continuous skin of different composition wholly surrounding the core and derived from another viscose, and optionally one or more intermediate zones having yet another composition or compositions and derived from yet another viscose or viscoses. Such a film may comprise a core and skin without any intermediate zone. The total weight of cellulose in the skin may be at least 2%, preferably at lesat 5% of the total weight of cellulose in the film, and the skin only may contain an anti-blocking agent, a surface-active agent, an agent adapted to render the film heatsealable, or hydroxyethyl cellulose. The films are made by feeding viscose through a pipe-line to a hopper from which it is extruded in film form into a coagulating bath, different viscoses being caused to flow coaxially through the pipe-line, in such a way that of any two adjacent streams of different viscoses, one completely surrounds the other. A stream of viscose from which the core of the film is to be made may be fed axially through a pipe-line into the interior of a main pipe-line through which the viscose from which the surface layers are to be formed is already flowing. Suitably the main pipe-line is of circular cross-section and the second pipe-line elliptical.

Title: Preset dimension compensator for a numerical control system
IPC: G05B19/35
Filed: 1968-06-28
Abstract: 1,200,521. Programmed control of machine tools. KEARNEY & TRECKER CORP. June 28, 1968 [June 28, 1967], No.30896/68. Heading G3N. A numerically controlled machine tool incorporates a compensation selector matrix interconnected with a position register to transmit add or subtract signal pulses for modifying command signal pulses from the numerical control system. As shown, Fig. 3 position and velocity commands read from a tape by a reader of a data input system 76 are fed to a command register 95 and a velocity control 98 respectively. The control 98, in response to pulses from a reference counter 64, determines the feed-rate of a member 16 driven by a motor 26 and the direction of movement of the member is determined by a count control responsive to signals from a bit comparator 115 comparing the commanded position in register 95 with the count in a register 110, accumulating, in accordance with the direction of movement the commanded feed-rate pulses from a count control 105. The commanded feed-rate pulses are fed to a phase-counter 74 determining the magnitudes of the quadrature signals from supplies 78A, 78B fed to a bridge circuit 43 of a linear inductive position determining transducer 28. The error signal from the bridge circuit 43, through a preamplifier and filter 89, and a square-wave chopper 71 is fed to a discriminator 17 controlling the direction and speed of rotation of the motor 26. Known thermal distortions of the transducer are compensated by actuating a compensation dimension decoder 138, by the count in the register 110, whereby a compensation selector switching matrix 45 is enabled, to initiate a compensation signal. The compensation signal from the matrix 45 is fed through a decoder 143 or 145, enabled in dependence on the direction of movement determined by count control 105, to inhibit a normal count gate 129, whereby the commanded position of the member is reduced by a unit, or enable a double count gate 122 whereby the commanded position is increased by a unit. As shown, Fig.4, the compensation switching matrix comprises positive and negative compensation bus-bars 47, 48 which are directly connected to the decoders 143, 145, Fig.3, and selectively connected by screw-plugs S50, S51, S148, S152, S153 to the compensation dimension decoder 138. The decoder 138 comprises a logic network whereby a pulse is fed through the appropriate screwplug to line 47 or 48 when the count in position register 110 corresponds to the selected position values shown. The range of selected position values is extended by an additional decoder 138A. In a modification, Fig.3A, (not shown), a temperature controller operates a relay at a selected temperature to transfer the compensation decoder to a high temperature switching matrix.

Title: Apparatus for automatic display of goods for sale, and in particular of wearing apparel
IPC: A47F3/08
Filed: 1929-10-11
Abstract: 336,101. Koller, R. April 24, 1928, [Convention date]. Boards and like elements, travelling. - Clothing, carpets, umbrellas, &c. are displayed by suspending them in a row from an endless chain c, Fig. 2, and bringing the articles in turn to a display position P<4> by means of a trolly M<2> running on an endless rail a. The chain c moves intermittently and advances the space between two articles during the time that the empty trolly M<2>, starting at P<1>, takes to reach the point F<2>. The article is here taken up by an arm F pivoted at P<6>, and the trolly moves this arm to the point P<9> and transfers the article to itself. When the trolly reaches the position P<4> it stops and rotates the article through 180‹ or more, and then proceeds to the point P<1>, an arm pivoted at P<4> optionally co-operating with it to transfer the article to the rear end of the chain c. The arm F is extensible and has a universal joint, near the axis P<6>, controlled by springs z, z<1>, Fig. 5. The articles are caught from the chain c on to a hook S, and are thence transferred to a member T on the trolly M<2> by an upward and outward movement of the end of the arm F during its rotation by the trolly. This is effected by rollers n, n<1> on the arm F engaging an incline u. The spring z<1> returns to arm point P<2> when it is released from the trolly. The member T may be a hook, or a cramp opened and closed by projection on the rail a and chain c. The chain c is arranged in a vertical plane, and the links have rollers c<4> Fig. 9, by which they ride over a ledge b. The articles are supported in grooves c<1> in the links, and the chain is fed forward by engagement of the moving trolly with projections on an endless chain connected with the chain c through pawl and ratchet gearing. This gearing may be disconnected to allow of adjustment between the trolly and the suspended articles. The trolly is driven by a motor M which through belt and worm gearing rotates a shaft k and toothed wheel k<2>, Fig. 15, engaging a rack in the rail side. At the display position a section of the rack is attached to a drop rail q which is swung sideways by a roller W on the trolly, thus disconnecting the wheel k<2> and stopping the trolly. A toe q<2> on the rail q acts through a bell-crank member i<6> to force down a pinion i<2>, thus rotating a shaft T<5> from which the article is suspended. When it has made a full revolution a lever connected to the shaft T<5> releases the roller W to allow it and the rail section q to rise under the action of a spring and re-engage the wheel k<2> with the rack. The pinions i<1> and i<2> are simultaneously disengaged by a spring i<8>. Two or more trollys may be employed. The cable connecting the trolly to the switch X is run over pulleys and held taut by a pulley weight.

Abstract: 652,384. integrating circuits. BRITISH BROADCASTING CORPORATION, MAYO, C. G., TANNER, R. H., and WHARTON, W. Nov. 21, 1947, No. 30984. [Class 40 (vi)] [Also in Group XXXVI] In an integrating circuit of the type in which a capacitor connected between the output and input terminals of an amplifier is charged through a resistor connecting to the signal source a unilateral conducting device is connected in series with the capacitor to prevent the capacitor discharging when the signal ceases. In a Miller integrator circuit a diode 14 is connected in series with the feed-back capacitor 13 so that when the signal from source 15 terminates the final state of charge of condenser 13 is maintained. A valve voltmeter 21, 22 calibrated in the desired units and having a very large input resistor 20 measures the voltage on the diode side of the capacitor. The circuit shown integrates positive going signals but if the diode is reversed negative signals may be integrated. In an alternative arrangement (Fig. 3, not shown), the feed-back path is connected instead to the cathode resistor of a preceding valve in a multi-valve amplifier and comprises two oppositely arranged diodes in parallel, each in series with a capacitor. Separate integrals of the positive and negative parts of the input signal are available across these capacitors and the mean value may be developed across a capacitor in series with the two diode-capacitor arms.
