Title: Coating process and product
IPC: D21H19/40
Filed: 1964-09-14
Abstract: Paper sheets for manifold record material is prepared by hydrodynamically applying to a paper rawstock, using a blade coater, a coating composition containing attapulgus clay in the form of clusters or bunches of needle-like particles.  The attapulgus clay may be added to the coating composition while the latter is in doughlike consistency.  The paper rawstock may have a relatively rough surface or may have a Sheffield smoothness of the order of 200 to 250.  The coating composition may contain 64 to 75 parts by weight of attapulgus clay to 100 parts by weight of total solids together with minor amounts of sodium pyrophosphate, silica pigment, sodium silicate, starch and butadiene-styrene copolymer in latex form.  The composition may have a solids content in the range of 38 to 42% by weight total solids and a MacMichael viscosity of 40 to 70 poises at 20 DEG C.  The paper rawstock may have a Sheffield smoothness of 225 and the coating composition consists essentially of 70% attapulgus clay, 1% sodium pyrophosphate, 8% silica pigment, 5% sodium silicate, 1% starch, and 14% butadiene-styrene in latex form, the percentages being by weight of dry solids, and has a solids content of 41% by weight total solids and a MacMichael viscosity of 50 poises at 20 DEG C.  A paper rawstock having a Sheffield smoothness of 135 maybe tubsized on that side with a pigmented size comprising 66% (dry solids) attapulgus clay prior to applying the coating composition. The coating composition may consist essentially of 70% attapulgus clay, 1% sodium pyrophosphate, 10% silica pigment, 5% sodium silicate, 3% starch and 11% butadiene-styrene in latex form, the percentages being by weight of dry solids, and has a MacMichael viscosity of 40 poises at 20 DEG C.  Water as a thin starch solution may be applied to the backside of the sheet followed by drying to control curl.

Title: Apparatus for measuring the velocity of a moving body
IPC: G01S13/58
Filed: 1971-08-10
Abstract: 1364549 Doppler radar FRANCE ARMED FORCES MINISTER OF 10 Aug 1971 [10 Aug 1970] 37587/71 Heading H4D A Doppler velocity measuring apparatus in which the beat frequency signals are converted to a constant amplitude pulse train whose repetition frequency is a multiple of the beat frequency includes means for counting the pulses during a preselected time interval to determine the velocity. In apparatus for measuring the velocity of a projectile fired from a gun, the transmission frequency is chosen to be 9À368 GHz and thus by multiplying the Doppler frequency by eight and using a measurement interval of 20 ms. the total count represents the velocity in decimetres per second. Received signals are mixed with the transmitted signals and the beat signal squared in a comparator before being fed via a Doppler filter to two frequency doublers, which include full wave rectifiers and transistor impedance matching stages (Fig. 4, not shown). A third doubler 13 comprises a clipper followed by a differentiator. The positive and negative pulses are then separted, the negative pulses inverted and recombined to produce pulses at twice the input frequency. These pulses are fed to a counting unit (Fig. 7). Signals from a sound pick-up indicating that the gun has been fired pass through delay 38 and open gate 34. This allows clock pulses from 100 KHz oscillator 40 to pass to decoder 35 via four divide-by-ten units 33. Decoder 35 opens gate 36, closes gates 36, 37 and opens gate 37 respectively during three successive twenty millisecond periods. At the end of the third period gate 34 is closed. Counters 30, 31 thus represent two measurements of the projectile velocity which can be compared to invalidate the measurement if either is not within expected limits (e.g. due to false measurement caused by reflecting objects in the flight path) and also to study the change in velocity along the flight path.

Title: Improvements in or relating to Stepping or Synchronous Motors
IPC: H02P8/04
Filed: 1967-08-16
Abstract: 1,199,793. Control of A.C. motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Aug., 1967 [19 Aug., 1966], No. 37619/67. Heading H2J. A synchronous motor is energized from an oscillator whose frequency automatically increases from an initial value, chosen so that the rotor can "lock on" from rest, to the desired operating frequency. As shown, the motor is a stepping motor having a permanent magnet rotor and four stator windings A energized sequentially from the pair of transistor bistable multivibrators shown at P. These are switched by pulses from a free running astable multivibrator comprising transistors 1, 2 and capacitors 3, 4, at a frequency controlled by the conduction of a transistor 24 which depends upon the state of charge on a capacitor 40. Oscillations start when switch S is opened; capacitor 40 is initially discharged and the controlling voltage at the emitter of 24 is substantially the -24 volts on line 12. This voltage linearly approaches zero, and the oscillator frequency thereby increases, as capacitor 40 is charged at constant current through transistor 38. The frequency of the supply to each stator winding A is one quarter of that of the driving pulses from astable multivibrator 1, 2. In an alternative embodiment (Fig. 4, not shown) the motor is a synchronous machine having a single main stator winding and an auxiliary winding in series with a capacitor so that it starts in the required direction. Both windings are energized via a transformer supplied from an RC oscillator as described in Specification 1,119,708, which is a multivibrator whose frequency increases as a capacitor is charged from the supply via a resistor which is tapped so that the final frequency can be selected. A capacitor in series with the motor causes the motor voltage to increase with frequency. The first embodiment is for driving a magnetic tape and the second for the turntable of a record player. Suitable components are listed.

Abstract: 343,235. Toys. MANSOUR, J. N., 47, Scaris brick New Road, Southport, Lancashire. Dec. 12, 1929, No. 38087. [Class 132 (iii).] Streamline bodies of model toys such as aeroplanes, submarines, yachts, boats, and motor cars, wheels and other parts to be used in conjunction with the toys, are made by cutting from tough paper two or more blanks of appropriate shape, damping the blanks to render them pliable and moulding them between a hollow mould and complementary former, the seams or joints being glued together under pressure. In the construction of an aeroplane fusilage, the blank A, Fig. 1, is damped and placed in a hollow mould internally shaped to the contour of the fuselage, and the piece B, Fig. 2, is also damped and inserted in the mould so that it overlaps the edges of the slit a. Glue or other adhesive is then applied to the joints. An electrically or otherwise heated solid former working in guides, suspended by links from levers which are secured to a rotatable shaft, descends into the mould to shape the blanks. The adhesive may be a cement which is impervious to water but becomes adhesive under heat at one temperature and dry at another, such as shellac varnish. The hull of a boat or yacht may be moulded in a similar manner and the deck may be made of a flat sheet of paper or wood. Wheels for aeroplanes and similar models are made up of two paper discs H, Fig. 10, each disc of one or more thicknesses moulded or pressed to shape with flanges h; between these flanges a flat paper ring K over which a padding k of kapok, cotton, wool or other soft material has been bound, and a strip k<1> of nainsook or other fabric is glued to simulate a tyre ; a hub M with a metal cap m secured in the centre completes the wheel. In the case of an aeroplane or submarine body, a double mould may be used which is divided at or near the centre, the paper blanks for the bottom being placed in one and the paper blanks for the top being in the placed other, and the two brought together with a former between them. In the construction of boats, hulls, &c., the blanks are cut out in duplicate and glued together to give extra stiffness, and reinforcements such as strips of cane may be used.

In a centrifuge for separating non-homogeneous liquid mixtures a ring-shaped acoustic radiator serving to increase the efficiency of separation is mounted on the peripheral wall of the rotor of the centrifuge or of a cup inserted in the rotor. In Fig. 1, an acoustic radiator 5 is mounted on the inner surface of the wall of a rotor 1 which is replaceably secured to a shaft 2 mounted in a ball bearing support 3 and driven through a pulley 4. The radiator, which may be of the piezoceramic or magnetostrictive type, is insulated from the wall of the rotor by plastics straps 6 and is connected by wires extending through a tube 8 to a terminal device 7 in turn connected to a high-frequency oscillator (not shown). Water is fed through the tube 8 for cooling the radiator 5 and is withdrawn through a hole in the rotor into a receiving chamber 9 in a protective casing 10. The liquid mixture to be separated is introduced into the rotor through a pipe 2. The high-frequency energy is converted by the acoustic radiator into ultra-sonic oscillations which causes coagulation of certain constituents of the mixture thereby facilitating its separation into light and heavy fractions under the action of centrifugal force due to rotation of the rotor. The light fraction passes through the whole rotor and into a receiver 18 while the heavy fraction is removed from the rotor by means of known unloading devices. The centrifuge may be used for separating suspensions of finely dispersed polymer particles in water or for classifying electrocorundum particles in suspension in a liquid. In Fig. 2, cups 14 to be filled with the liquid mixture to be separated are inserted in sockets in a centrifuge rotor 13. Acoustic radiators 15 are mounted on the walls of the cups. Highfrequency energy is supplied to the radiators via a terminal device 16 and contacts 17.
