Abstract: 135,831. Nishigawa, T. Nov. 29, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Sodium bicarbonate; ammonium chloride.-The mother-liquor of the ammonia-soda process is treated with an amount of sodium chloride equivalent to the bicarbonate that has separated, and is cooled to a temperature not above 50 C., while ammonia is introduced in quantity sufficient to convert the bicarbonates present into carbonates. Ammonium chloride separates, and the sodium bicarbonate present is converted into sodium chloride, so that the mother-liquor left after the separation of the ammonium chloride is suitable for use as brine in the ammonia-soda process. The ammonia required is obtained by treating the nitrogen issuing from the carbonators to form cyanamide, which is then treated to obtain ammonia ; or the nitrogen may be used to obtain synthetic ammonia by the catalytic process.

Title: Improvements in and relating to methods and apparatus for heating by high frequency electromagnetic fields
IPC: H05B6/78
Filed: 1948-11-04
Abstract: 668,835. Dielectric heating BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 4, 1948 [Nov. 7, 1947], No. 28697/48. Class 39(iii) Apparatus for heating an article by highfrequency electromagnetic energy of the type including a means for varying the pattern or mode of a standing wave applied to the article without changing the connection between the source of energy and the applicator, is characterized in that the applicator comprises a cavity resonator in which the article to be heated or a portion of it is located, the resonator being coupled via a transmission system, preferably including a coupling loop, to the source of high-frequency energy. Fig. 4 shows one example of such an apparatus in which a plurality of high-frequency generators are provided at f 1 , f 2  and f 3  connected to a resonant chamber 2 by transmission lines 14, 15, 16, the article to be heated, for example a paper roll 20, passing through the resonator via aperture 17, 18. The frequencies of the generators f 1 , f 2 , f 3  are each adjusted to sustain one of a plurality of modes of oscillation of which the cavity resonator is capable. The composite oscillations thus produced provide overlapping of the standing wave patterns produced by each mode so that nodal and antinodal points largely cancel out and uneven heating effects are reduced. Alternatively a single variable-frequency high-frequency generator may be employed to excite each of the plurality of modes of oscillation in turn. A magnet or oscillator may conveniently be employed for this purpose, exciting the various modes in random manner by reason of its inherent tendency to generate a plurality of frequencies in different modes and to jump from one to another during operation. Fig. 7 shows an arrangement employing a magnet or oscillator 24, with an adjustable sliding "trombone" sleeve 31 short circuiting by means of the branching section 32, 33, part of the transmission line to facilitate operation in the manner described, suitable means (not shown) being provided.to vary the position of the " trombone until an unstable position is obtained with consequent jumping from one frequency to another. A further embodiment is shown in Fig. 8 wherein a periodic change of mode pattern is induced by a rotating metal plate 37 to vary the inductive and capacitative properties of the resonator periodically. The plate 37 may be rotated by means such as a motor 38. Deformation of the resonator 1 will give similar results and Fig. 9 shows a resonator with flexible end wall 39 and bellows 40. The end wall 39 is reciprocated by suitable means such as a motor 41 so that the longitudinal dimension of the resonator varies periodically while being energized by the oscillator 5.

Abstract: 1,197,291. Digital calculators. HEWLETTPACKARD CO. 21 June, 1967 [23 June, 1966], No. 28709/67. Heading G4A. In an electronic calculator, control apparatus normally regularly actuates instruction apparatus to give and direct execution of groups of one or more instructions (microinstructions), each group being normally given and executed during a different one of normally regularly recurring clock time intervals, at least some groups including a selected instruction. e.g. memory access, which must be executed after or requires a longer time interval to execute than other instruction(s) of the same group, the control apparatus being responsive to such a selected instruction for itself directing its execution and delaying the normally regular actuation of the instruction apparatus until the selected instruction is executed. Input.-All input is from a keyboard having keys for the digits 0-9 and for various operations. The identity of a key pressed is specified by a signal on one of two lines (meaning digit and operation respectively) together with a binary number from a diode matrix. A further signal is produced when any key is pressed, to cause the calculator to exit from a display subroutine and deal with the new input. Output.-A cathode-ray tube displays the contents of a keyboard register and an answer register. Programme sequencing (see also first paragraph above).-The states of flip-flops are decoded to select a microprogramme subroutine and a stage within it by driving a selected sub-routine drive line and a selected instruction drive line, the decoders being disabled during memory access. The drivers do not carry current except when in use, thus reducing power consumption. Memory.-The magnetic core memory holds six 13-character words and is addressable by character. Jump. -When a microprogramme sub-routine is left before completion to perform a common microprogramme sub-routine, i.e. one used during the execution of more than one macroinstruction, a so-called transfer vector is stored. On exit from the common sub-routine, the transfer vector (which has n bits if the number of possible transfer vectors is 2<SP>n</SP> or between 2<SP>n</SP> and 2<SP>n-1</SP>) is retrieved and expanded into an address to transfer control to. Tester.-A tester unit can be plugged into the machine and displays the states of most of the flip-flops of the calculator on lamps. It includes a conditional halt switch to cause the calculator to stop at a particular combination of states of these flip-flops, the desired states being set up on manual switches (one per flip-flop) each having 3 positions meaning 1, 0 and don't care respectively. A dump switch is also provided to cause the flip-flops to take up states specified by further 3-position manual switches (one per flip-flop), the 3 positions meaning set to 1, set to 0 and leave alone respectively. Single-step, halt, read and store switches are also provided.

Abstract: 1514791 Vibration measurement NIPPON SEIKO KK 10 July 1975 [12 July 1974]  29098/75 Heading G1G Damage to a rotator, e.g. a ball bearing, is detected by analyzing the cyclically-varying vibration produced as it is rotated. The vibration is converted to an A.C. electrical signal which is applied to a peak detector circuit the D.C. output level of which is periodically reset. The peak detector output is integrated to give a smoothed signal of which the amplitude is a measure of the degree of damage. In the embodiment described the amplified output 1 of a vibration pick-up (e.g. microphone) is filtered to remove low frequency components. The filtered signal 2 is passed to the peak detector. The output of the detector is shown at 3 for the case in which the detector is reset to the prevailing signal magnitude at intervals greater than the  period of the cyclic variation of the vibration. The peak detector output 3 is filtered by an RC integrator network to give the damage-indicative D.C. signal 4 for application to a meter, alarm or relay. The periodic resetting of the peak detector ensures that non-persistent spurious noise is not interpreted as damage-induced vibration.
