Abstract: 1,207,521. Transistor oscillator circuits; keying oscillators. HONEYWELL Inc. 13 Sept., 1967, No. 38922/67. Headings H3T and H3R. [Also in Division G1] An oscillator comprises a mismatched distributed resistance/capacitance phase shift element 23, Fig. 2, and a coupling element connected between the output and input of an amplifier formed by transistors 20 and 21. In Fig. 2 part of the feedback circuit is shunted by a variable capacitance, shown as a transistor 30 the capacitance of which depends on the voltage at terminal 29, and it is shown that the phase shift is 0 degrees or - 180 degrees according to whether the ratio of the capacitances is more or less 17À7, and the circuit oscillates or not accordingly. The circuit may be constructed as an integrated circuit, Fig. 4 (not shown). In a modified circuit, Fig. 3 (not shown), the collector of transistor 21 is connected to a separate tapping on element 23 from that connected to transistor 30. The change of phase shift may be produced by a variable resistance connected to the capacitive terminal of the phase shift element, Fig. 5 (not shown). In another arrangement, Fig. 7, the RC line 123 is formed of semi-conductive material exhibiting a piezo-resistive effect so that the circuit oscillates continuously at a frequency dependent on pressure.

[Also in Divisions B6, E2 and F2] A luggage case comprises two plastics shells 10, 10<SP>1</SP> (Fig. 2) held in channels 29, 51 (Fig. 16) in a pair of metal frames hinged at H (Fig. 2) and having interconnecting tongues and grooves along their tops and ends with the top channels 29, 51 (Fig. 16) spaced outwardly from those on the ends. The inner edges of the tongues are coplanar providing an extended top tongue 57 which houses two locks (see Division E2) and a handle 12 (Fig. 2). Latches extending through slits in the channel 29 (Fig. 16) and riveted to an inner top flange 31 engage in locks mounted on the opposite tongue frame. The shells 10, 101 are adhesively secured to the lightweight metal frames and are additionally held in position by hard metal clips C (Fig. 20) having a flange 87 extending around the edge of the shell and downwardly bent sharp corners 91 which catch on the softer metal frames, and upwardly bent prongs 88 which pierce the plastics shells. The base hinges H (Fig. 2) (see Division E2) have feet 97 and the case may be maintained in any open position by friction hinges L (see Division E2). The case is lined with material 107, 108 attached by the rivets retaining the hinges H, and an extension of material 108 or a separate piece bridges the gap between the two shells and is sewn to the material 107. A hook 111 engages the lower end of a writing tray (see Division B6) which is retained at its upper end by stops 119 covering the inside of apertures in the tongue frame which are used in the locking device.

Title: Improvements relating to the determination of the rate of flow of a fluid
IPC: G01P5/07
Filed: 1958-12-04
Abstract: 893,556. Fluid-flow meters. COAD, S., DAY, W. A., BUCKINGHAM, J., and WRIGHT, C. J. Dec. 4, 1958, No. 39139/58. Class 69 (1). [Also in Group XXXVIII] A device for measuring the rate of fluid flow comprises means for causing a magnet assembly to rotate relative to an oscillatable armature which oscillates between contacts and thereby successively charges and discharges a condenser to give a measure of the rate of flow. The device may be used for measuring the flow of liquid or gas in a pipe, but is particularly suitable as a towed or attached ship's log, or, when anchored, for measuring water currents. For this purpose the device (Fig. 5) comprises a streamlined plastic watertight housing 25 containing a shaft 26 on which is mounted another housing 27 fitted with vanes 34 for rotation by the water currents. One or more magnets 30 are mounted equidistantly in the housing 27, and as the latter rotates, the magnets pass in front of a further magnet 35 in the fixed housing 25. This magnet is pivoted on a bar 36 and is caused to oscillate from side to side as the other magnets pass it. The other end of the magnet 35 engages alternately a contact 45 and a similar contact on the other side, and thus successively charges and discharges a condenser for measuring the rate of operation of the contacts (see Group XXXVIII). In a modification (Fig. 1, not shown), the magnets 30 are placed radially and the oscillating magnet is adjacent to them so that it moves towards and away from the axis of the rotor. When towed by a ship a suitable paravane attachment coaxial with the cable ensures that the device is submerged to a predetermined depth. For use with a pipe line the oscillating armature is preferably located outside the pipe. The apparatus can be adapted to calculate the distance travelled by a ship, and hence its position.

Abstract: An alkali metal sulphate or alkali metal Mg sulphate is prepared by reacting an alkali metal chloride with MgSO4 or an alkali metal Mg sulphate in the presence of an organic solvent selective for MgCl2. The solvent may be methanol, ethanol, acetone, or dimethyl formamide, alone or mixed, or with water. Starting materials referred to are KCl, NcCl, KCl-NaCl, anhydrous MgSO4, MgSO4.7H2O, kieserite, and K2SO4.MgSO4.6H2O (shoenite), and the end product may be K2SO4, Na2SO4 (themardite), shoenite, Na2SO4.MgSO4.4H2O (astrakanite), or Na2SO4.3K2SO4 (glaserite).  These processes are described (with reference to Figs. 1, 2 and 3 resp.) each using methanol and water as solvent:  (1) Reaction of KCl and MgSO4 to give a mixture of K2SO4.MgSO4 and KCl. MgCl2.2H2O is recovered by spray-drying.  (2) Reaction of K2SO4.MgSO4 and KCl to give K2SO4.  The methanolic MgCl2 solution is mixed with MgSO4 and brine (obtained in the decomposition of camallite) to give the K2SO4.MgSO4 required.  (3) A solid mixture of K2SO4.MgSO4 and KCl is suspended in methanol to obtain K2SO4.  The MgCl2 solution is mixed with KCl and MgSO4 and a NaCl-KCl mixture to give the required starting mixture and further MgCl2 solution, which is mixed with camallite brine to give the required NaCl-KCl.  The reactions are effected in stirred vessels followed by thickeners. Products are recovered in a centrifuge or on a water sprayed band filter, and the liquid recycled.  The final MgCl2 solution may be passed through a vacuum evaporator and then to a steam-injected distillation column.  The vaporized methanol is condensed and recycled.

A number of series connections formed by load transistors Q25-Q28 and transistors Qd12- Qd 17 may be connected in parallel with the output of one connected to the input of the other via transfer gate transistors Qt1-Qt3 to form a two phase two bit dynamic shift register. In operation, when the clock pulse 91 attains a "0" level, transistors Qdl6, Qd12 and Qt1 are rendered conductive so that a signal V1 which is the complement of an input at Vin is obtained and is stored in the gate capacitance of Qd13. Subsequently when a further clock pulse # 2  turns on Qd17, Qd13 and Qt2, the complement of the stored signal, i.e. the same as the input at Vin but delayed by 1 bit period of the clock pulses is stored in the gate capacitance of Qd14 and the final output obtained via Qt4 corresponds to a delay of 2 bit period of the clock signals. The logic circuit block may be formed by an AND-OR combination (Fig. 1, not shown) or by a 2 input NAND gate (Fig. 2, not shown). The single or parallel combination of the series connections of Figs. 1, 2 are for deriving logical relations in terms of the various signals applied.
