Title: Improvements in or relating to voltage monitoring devices
IPC: H03K3/2893
Filed: 1961-04-11
Abstract: 940,086. Transistor circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 11, 1961 [April 14, 1960], No. 13015/61. Heading H3T. [Also in Division G1] A device for monitoring the level of a direct voltage between two limit values b, d comprises a switching voltage generator 3 consisting of two bi-stable transistor circuits 7, 8, the output of the former being connected to a feedback circuit of the latter, and the arrangement being such that a relay 4 included in the output of circuit 8 is energized as long as the signal lies between b, d but de-energized to operate an alarm 6 when the signal lies outside these limits. The output from circuit 7 is supplied to the feedback circuit between transistors 11, 12 through voltage divider 18, 19. Operation.-If there is no input at 1, 2, transistors 9, 11, 12 are blocked, transistor 10 conductive, relay 4 de-energized. If the negative input at 1, 2 is now raised, transistor 9 will become conductive and transistor 10 blocked as soon as the input exceeds the voltage across resistor 13. Transistor 12 also becomes conductive since there is a voltage increase at its base as collector current from transistor 10 no longer flows through resistor 14. Relay 4 is, therefore, energized. Further increase in the negative direction to level d causes a changeover of circuit 8, thereby blocking transistor 12 and de-energizing relay 4. Similarly, relay 4 will be de-energized when level b is exceeded. Circuit details.-To compensate for temperature and ageing effects and to adjust the operating point of relay 4, a voltage divider 26, 27 is connected to the base of transistor 12 via a diode 28. In order to avoid oscillation of the relay, a hysteresis effect is provided such that when the input changes in the reverse direction, the relay is energized at levels e and c. The hysteresis effect is adjusted by resistors 20, 21 and 22, 23 which vary the emitter currents of 9, 11 respectively.

Filed: 1934-05-01
Abstract: 435,941. Indicating-apparatus; supply meters. LEES, J. B., 86, Langham Road, Oldham. May 1, 1934, No. 13137. [Class 106 (iv)] [See also Group XXXVI] A device showing whether or not periodically recurring operations are being correctly performed comprises an indicator moved at a constant rate and means which become active at each periodic operation, if such operation is effective, to return the indicator to zero. The invention is shown as applied to a periodically-closed circuit which is connected to a maximum-demand indicator. A synchronous motor a drives the indicator r of the invention against the action of a spring t. Comprised in the drive is a cam b, which, during its rotation, closes contacts 4, 5 for an adjustable time and then opens them again. While the contacts are closed, an electromagnet y is energized to move a pinion o out of contact with a pinion p so that the spring t can return the indicator r to the zero position, not shown. The circuit z completed by the contacts 4, 5 also controls a maximum-demand indicator. Should the contacts 4, 5 fail to operate, or should there be a failure of the supply to the circuit z, the indicator r will not be returned but will be driven forward beyond a spring stop 8. If the contacts function correctly during the next revolution of the cam b, the indicator r will not be able to return past the stop 8 and the failure will thus be indicated.

Title: Improvements in or relating to fertilizers
IPC: C05C1/00
Filed: 1933-05-05
Abstract: The vapour pressure of liquid ammonia or ammoniacal liquors is lowered, preferably to such an extent that they may be transported in containers adapted only to resist pressures not substantially greater than atmospheric, by preparing a solution of urea and a fertilizing salt of a strong inorganic acid in the ammoniacal liquid.  The urea and fertilizing salt are preferably used in an amount sufficient to form a solution substantially saturated with solid components at temperatures below about 30 DEG  C., and preferably not lower than -30 DEG  C.  Fertilizing salts specified are ammonium sulphate, nitrate and chloride, potassium nitrate and chloride, sodium nitrate and calcium nitrate.  The fertilizing salts need not be used in the solid form e.g., calcium nitrate may be used in the form of the acid solution obtained by treating basic calcium materials with excess nitrogen oxides, or nitric acid and urea may be used in the form of the water containing product obtained in the synthesis of urea from ammonia and carbon dioxide.  The ammoniacal solution may also be obtained by absorbing gaseous ammonia in the solid components or in a slurry or aqueous solution thereof.  Fertilizers may be obtained by treating an acidic fertilizer material e.g., superphosphates, with the solutions; other fertilizing material, e.g., compounds of ammonia or potassium, cottonseed meal, &c., and diluents, e.g., sand, may be added at the same time.  The Specification as open to inspection under Sect. 91 also refers to ammoniacal solutions of calcium nitrate containing no urea. This subject-matter does not appear in the Specification as accepted.
