Abstract: 972,863. Filing papers. EASTMAN KODAK CO. Jan. 24, 1962 [Jan. 30, 1961], No. 2652/62. Heading B6E. A card separator adapted for cooperating with a stepped shingling plate to arrange a stack of cards in an overlapping array comprises a frame having a depending member for engaging the trailing edge of the stack and means for engaging the top of the stack whereby pressure may be transmitted to urge the lowermost card in the stack against said stepped surface, said depending member, which in use engages the trailing edge of the stack, permitting the lowermost card to pass therebeneath when that card is halted by a step on said plate. The plate is provided with a centrally placed stepped portion 26 and smooth sides 22 and 24, as described and claimed in Specification 972,865. The plate is located between upstanding side walls 16 and 17 of a base member 10. The card separator 12 is formed as a frame by front and rear members 31 and 32, and side bars 34 and 36 to provide a central well in which a stack of cards is placed. A weighted follower 62 sits on top of the stack to press the lowermost card against the steps. The weighted follower consists of a flat plate 64 having a handle 68 and upstanding side walls 72 and 74 bent outwardly to overlie the side bars 34 and 36. The front member 31 is supported clear of the steps by legs 41 and 42, but rearwardly at 44 and 46 to engage the sides 22 and 24. The rear member has a depending extension or bar 54 at its lower edge. Alternatively, the card separator comprises a U-shaped member 12<SP>1</SP>. The front leg 82 of said member is bent rearwardly to provide a foot 86. Leaf springs 87 are secured to the foot to apply pressure to the top of the stack. The rear leg 84 carries a transverse, resilient, flexible, depending skirt 89. Specification 972,864 also is referred to.

Title: An improved process and apparatus for the liquid treatment of yarn in hank or skein form
IPC: D06B3/08
Filed: 1930-01-27
Abstract: <PICT:0347284/IV/1> <PICT:0347284/IV/2> <PICT:0347284/IV/3> <PICT:0347284/IV/4> Hanks or skeins of yarn are desulphurized, bleached, acidified, and soaped, being washed after each treatment in successive baths, and during the treatment, are immersed and rotated and simultaneously sprayed with liquid from vats or the like arranged above the baths.  The hanks may be treated in groups which are successively moved from one bath to another, or may be continuously and individually moved through the baths.  In the group treatment, hanks are hung on rotatable rollers 1, Fig. 1, on carriers 2, and dip into vats 5 and are sprayed from pipes 7, the rollers 1 being rotated by gears 33 on a shaft 32 extending lengthwise of the machine.  After treatment, the vats 5 are lowered and the carriers 2 moved forward on rails 4 by means of arms carrying half-nuts engageable with a shaft 34, until each group of hanks is over the next vat, whereupon the vats are raised and the treatment continued.  The carriers are returned to the initial position by a travelling crane 12.  Overflow from the vats 5 collects in tanks 9 from which it is pumped to the sprayingpipes.  In the continuous treatment, hanks 13 are hung on porcelain or glass rods 14, Fig. 5, supported on a chain 22 and rollers 23 which run on rails 24, 25, thus causing the hanks to rotate.  The hanks dip into vats 18, and are sprayed from tanks 17, the excess liquid in the vats being returned to the tanks. When the hanks reach the end of the first vat they are lifted and transferred to the next vat by a chain 19.  The conveying-chain comprises double links 20, 21, Figs. 6 and 7, provided with two rows of rollers 22 of which the outer row is rotated by contact with a rail 24, so that the rods 14 which rest on the rollers 22 are rotated in an anticlockwise direction.  A further rail 25 is so staggered in relation to the rail 24 that it engages rollers 23 carried by the links, which cause the inner row of rollers 22, and hence the rods 14, to rotate in the opposite direction.

Title: Bearing determination using secondary surveillance radar
IPC: G01S13/78
Filed: 1972-08-24
Abstract: 1407092 Radio navigation LITCHSTREET CO 24 Aug 1972 [15 Sept 1971] 02890/74 Divided out of 1407091 Heading H4D The disclosure is the same as that in Specification 1,407,091, the claims however relate to a method of determining one's own bearing from an S.S.R. The S.S.R. omnidirectionally transmits a reference signal as the main radar sweeps through a reference direction. The method comprises receiving the reference signal, receiving interrogation signals from the radar as the main beam sweeps by one's own location, measuring the time interval between successive reception of either the reference signals or interrogation signals to produce a representation of the beam rotation interval, measuring the time interval between reception of a reference signal and reception of the next interrogation signal, and producing a quotient determined by the division of the second said time interval by the first said time interval, the quotient giving the said bearing. In Fig. 1, a transponder 60 receives interrogation signals and a North pulse from S.S.R. 71, Fig. 2, the beam of which rotates in direction 136. Each time the S.S.R. beam points NORTH a pulse is received due to the omnidirectional transmission and computer 76 measures the time interval between such pulses. Each time the radar beam sweeps past own aircraft 72, replay pulse F1 are generated in response to the interrogation signal and computer 76 measures the time interval between a North pulse and the next reply pulse F1. The quotient of the second interval divided by the first interval gives #, one's own magnetic bearing from the S.S.R.

Title: Improvements relating to the separation of titanium dioxide hydrate from hydrolysable solutions of titanium salts
IPC: C01G23/053
Filed: 1929-01-28
Abstract: 310,949. Blumenfeld, J., (Assignee of Verein f³r Chemische und Metallurgische Produktion). May 5, 1028, [Convention date]. Titanic hydroxide.-The hydrolysis, under heat, of titanium salt solutions is assisted by the addition of a small amount of a nucleus liquor containing nuclei of titanic hydroxide which are still capable of being dispersed wholly or partially by dispersing agents into a condition of apparently homogeneous solution. The nucleus liquor may be obtained by hydrolysing a titanium salt of low acidity under heat, and subsequent cooling stabilizes the nuclei produced. For instance, a portion of the main solution may be added to an alkali until the acid concentration of the liquor has a pH value of 2-7 or preferably 4-4.5, hydrolysis be effected at 70-80‹ C. for say 15-30 mins., and stabilization be then obtained by rapid cooling to below 60‹ C.

Patent GB-646474-A (GB)
Title: Improvements in and relating to the frequency-control of relaxation oscillators
IPC: H03K3/08
Filed: 1948-02-03
Abstract: 646,474. Frequency modulation; relaxation oscillators. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd., and HOLLOWAY, D. G. Feb. 3, 1948, No. 3195. [Classes 40 (v) and 40 (vi)] Linear frequency modulation of relaxation oscillators is effected by providing separate resistors in the respective charge and discharge paths of the capacitor and by applying the signal voltage to control the current flowing in either or both of said paths. As shown in Fig. 6 the oscillator comprises a pair of valves 10, 11 with a common cathode resistor 14, the anode of the valve 11 being connected to the control grid of the valve 10 by a capacitor 13 and to H.T.+ by a resistor 12, and the grid of valve 11 being held at a fixed voltage by a capacity 18 and a connection to the junction of resistors 16, 17. Two series pairs of diodes or rectifiers 21, 22 and 23, 24 are connected across the supply and their respective junctions are connected to the grid of the valve 10 and to the voltage divider 16, 17. The signal is applied at terminal 34 and passes through valves 35, 36, amplifier 37, and polarityinverter 38. Output from the valve 38 is applied across a resistor 40 through a resistor 25 to the anodes of the valves 22, 24 ; and output with opposite polarity from valve 37 is similarly applied through a resistor 26 to the cathodes of the valves 21, 23. During the cycle of the relaxation oscillator, the charging circuit for the capacitor 13 includes the resistor 26 and the diode 21, and the discharging circuit includes the resistor 25 and diode 22. The times taken in charging and discharging are both inversely proportional to the instantaneous signal voltage, and the oscillation frequency is therefore substantially in linear relation with the signal voltage. The signalmodulated output is taken at terminal 41 from the anode of the valve 10. The output is also applied through a pair of limiter valves 43, 44 to a frequency counter device comprising diode valves 45, 46 giving as output a de-modulated signal which may be monitored at terminal 47 and fed back in negative sense to a grid of the valve 36 to improve linearity. The voltage developed across the capacitor 13 should be small compared with that developed across the resistors 25, 26 ; and the change-over time of the voltage at the grid of the valve 10 should be equal to C.R. where C is the capacity of 13 and R the resistance of the anode resistor 12. When the generated oscillation is of saw-tooth shape with steep return stroke, modulation may be applied during the forward stroke only.

Abstract: 124,522. Sheppard, G. A. March 4, 1916. Clinometers.-A clinometer comprises a smallbore tube having a U-shaped or similar portion of which one limb is provided with an enlargement or bulb, and the other contains the indicating meniscus; a scale may be arranged in the plane of the tube or parallel thereto against which the meniscus is read, or mechanism may be operated by the liquid to actuate a pointer moving over a scale. As shown in Figs. 1 and 4, a tube B of D shape is housed in a groove in a casing A, and has an enlargement B'. The straight part of the tube B<2> is covered by a glass plate D which has a lenticular portion D<1>, the glass being secured by end pieces F having bevelled edges engaging the ends of the glass plate which are similarly bevelled. A scale E which may have luminous markings is placed behind the glass plate, its zero mark being level with the enlargement B<1>, and is preferably of channel shape so as to enclose the sides of the glass plate. A strip of card G or the like bearing radium compound &c. may be placed behind the tube. In a modification, the tube B is of approximately circular shape, and! the scale &c. is arcuate in form. Other instruments mav be arranged within the clinometer, the construction shown having a cover-plate C in which is a circular central opening to accommodate an altimeter. By increasing the width of the clinometer, several instruments such as an altimeter, a revolution indicator, a speedometer, and a watch may be accommodated. As an alternative to the employment of a glass plate with a lenticular portion, a flat plate may be employed, and the tube beneath it may be of flattened or elliptical section so as to increase the width of the column of liquid. The glass plate may in this case be secured by small tongues of metal punched up to engage its ends. In the modification shown in Fig. 11, the tube comprises a bulb L connected by a transverse part to a vertical limb L<2>, and contains mercury. A piston M rides on the mercury and has a rod M' loosely connected to a lever N having a toothed rack N<2> meshing with a pinion N<3> on the pintle of a pointer P which moves over a fixed scale R. According to Provisional Specification 3304/16, the glass cover-plate D may be secured laterally by a flanged edge on the plate C and a separate flange secured to the casing A.
