Abstract: 1,249,334. Gunn effect flip-flop circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 29 Nov., 1968 [22 Dec., 1967], No. 56643/68. Heading H3T. In a monostable or bi-stable flip-flop arrangement including a Gunn effect device 1 connected in series with an impedance Z L  and a D.C. voltage source U s  the values of the impedance and D.C. source are such that the currentvoltage curve of the device 1 exhibits two stable working points I, III (Fig. 2), and one unstable working point II and the value of the voltage U B  and the real part of the impedance Z L  are such that a homogeneous field distribution occurs in the device 1 at least at the two stable working points I, III. With the Gunn effect device 1 biased at I when a trigger pulse is applied at IN sufficient to make the working point at II the device 1 switches to an unstable state and then returns to a stable state at I to form a monostable arrangement. If the input trigger pulse is of such an amplitude to make the operating point III the device then stays in this state to form a bi-stable arrangement until retriggered back to its initial state. The flip-flop can be constructed in integrated circuit form.
Patent GB-570484-A (GB)
Abstract: 570,484. Mail-marking machines. NATIONAL POSTAL METER CO., Inc. April 3, 1944, No. 6136. Convention date, May 5, 1943. [Classes 100 (i) and 100 (ii)] A mail-marking machine, which is especially applicable for printing on a gummed tape, is constructed in such a manner that passage of the paper through the machine is not interrupted by reason of jamming of the tape due to arching of the gummed side thereof. The tape 14 is guided by a tape shoot formed of a slotted bottom member 25, side members 20, 21, and an upper member 26 which extends under the printing roller 12 as far as a plate 31 with which the cutting knife 18 co-operates. The plate 26 is formed with an aperture 29 through which the roller 12 and an impression roller 15 operate, and the aperture 29 is joined to a tapered part 30 by an abrupt part 30a, so that if arching of the tape occurs it gets straightened out before reaching the cutting-devices. After the tape is cut off it is reversed by means of an oscillating gripper device 34 on a lever actuated by a cam 36 on the shaft 13 of the roller 15 which is revolved in a clockwise direction. The tape may be treated by a moistening device 19. Specification 356,840 is referred to.

Abstract: 1,202,878. Steam reforming methane. JOHN ZINK CO. 15 Dec., 1967 [15 Dec., 1966], No. 57191/67. Heading C5E. Effluent at 1500 F. from the conversion of methane to carbon monoxide and hydrogen by reaction with steam in a primary reformer is passed through the inlet 19 to the neck portion 14 of the housing of a combination chamber 12 of a secondary reformer. Sufficient air or air and steam at 300-1100 F. to heat the effluent to 2200 F. after combustion so that complete conversion of residual methane is obtained in the catalyst bed is passed down the conduit 21 and through the openings 27 in the burner head 22 (Fig. 4, not shown). A cylindrical jacket 31, spaced from the conduit 21 by a refractory lining 32, protects the conduit 21 from the heat of the incoming effluent. The jacket 31 carries an annular member 33 having holes 37 therethrough (Fig. 2, not shown) such that the area of the holes 37 plus that of the annular space 34 is about 1À5 times that of the inlet opening 19. The member 33 reduces the momentum of the incoming effluent and provides for its non-turbulent flow past the burner head 22. Fig. 5 shows an apparatus in which, instead of the annular member 33 shown in Fig. 1, a cylindrical shroud 46 is disposed about the conduit 21. This shroud 46 is closed at its upper end 47 and its lower end is open and has an outside diameter which fits within the refractory lining at the entrance to the chamber 12. Two diametrically opposed openings 48 are provided in the shroud through which the incoming effluent passes with decreased momentum and suppressed turbulence as it moves down between the shroud 46 and the conduit 21.

Abstract: 1459798 Lubricating SPIRAX SARCO Ltd 3 Dec 1974 [10 Dec 1973] 57212/73 Heading F2A [Also in Division B1] An airline lubricator has an airflow passage 2 having a venturi formed by a flexible resilient flapper 9; lubricant is induced through a riser tube 4, adjustable metering valve (5, Fig. 2, not shown) and a drip tube 6 in a sight dome 7. As shown, the coil then enters the airflow passage through an oil way 10 through the flapper but it may open through the body 1 clear of the flapper. The resilience of the flapper is such that it flexes in dependence upon the rate of airflow so that the airflow/pressure drop characteristic of the venturi varies with the rate of airflow in order to maintain the oil/air volume ratio more nearly constant. The drip tube may be mounted in the flapper so that both may be removed as a unit after removing the sight dome 7, see Fig. 3 (not shown).

Title: Q-Switch for Laser System.

Abstract: 1,163,110. Lasers. UNITED STATES ATOMIC ENERGY COMMISSION. 23 Dec., 1966 [2 Feb., 1966], No. 57701/66. Heading H1C. A Q-switched laser system comprises a saturable dye and a rotating mirror. Ruby or neodymium doped glass rod 10 is pumped by xenon flash tube 12 in reflecting housing 22. One of the mirrors 16 of the optical cavity is rotatable in housing 30, which housing also includes a light source 32 and light detector 34 for synchronizing the firing of xenon flash tube 12 with the rotation of the mirror, Fig. 2 (not shown). In operation light 36a from source 32 is reflected from surface 17 when mirror 16 is in the position shown at T 1 , Fig. 3, and the signal from photo-diode 34 is fed to a pulse generator with a built-in time delay t d . At time T 3  the flash lamp 12 is energized for a period of t p  during which time the laser rod is pumped. During the period from T 4  to T 5  whilst the rod is being pumped the reflectivity of the cavity is very low but as the mirror approaches the perpendicular just before the time T 5  some energy may be reflected back to the laser element. However, due to the saturable dye 18 the amount of light passing to the mirror is inhibited until the amount of energy absorbed is sufficient to bleach the dye. When this happens the mirror is perpendicular, time T 5 , and a pulse is obtained through partially transparent mirror 14. The dye solution may be cryptocyanine in methyl alcohol, vanadium phthalocyanine, and lithium phthalocyanine.

Abstract: 1404864 Producing bubbles in a liquid SCHRAMM INC 15 Dec 1972 58200/72 Heading B1C Apparatus for releasing air bubbles into a body of liquid consists of a distributing conductor of large hose sections 18, 20 and 22 and a bubbling hose of sections 40, 42 and 44. The sections are joined together by "H" fittings 32, 34, 36, 38. Fig 5 shows a cross-section of the conduits; the bubbling hose consists of three passages 74, 76, 78 with passage 76 having an opening 80 to allow the escape of air to produce bubbles. The conduits may be weighted, particularly with lead, to aid their retention in a body of liquid. Fig 10 shows an "H" section with a restriction passage 104. This reduces a high pressure in the disrtibuting conductor from supply compressor 12 and the frequency of the "H" sections ensures that air within the bubbling hose is maintained at a substantially uniform pressure throughout its length. Fig 14 shows a further arrangement of restrictions which is easily adjustable by screwing of stems 214. Other restriction arrangements are shown. The assembly of conductor and hose, is flexible so that it can be wound onto spools.

Abstract: A speech processor, e.g. in a hearing aid, has an automatically varying gain control determined by the amplitude of the input averaged over successive short time intervals (optimally 27 ms). For averaged signals below a threshold level of about one-fifth of the peak the gain is decreased with increasing amplitude, and for averaged signals above that threshold the gain is increased with increasing amplitude. The processing circuit comprises a main amplifier 12 for the input signals and a parallel gain control path comprising an integrator 16 which integrates input signals over each time interval and a level switch 18 which switches inputs above and below the threshold to an antilog circuit 19 or to an amplifier 20 respectively. Circuit 19 provides an output exponentially related to the input and amplifier 20 has a linearly decreasing characteristic.
