Title: On-speed detection arrangement
IPC: G01P3/489
Filed: 1972-12-07
Abstract: 1362740 Speedometers ITT CREED Ltd 7 Dec 1972 56486/72 Heading G4D [Also in Division G1] An on-speed detection circuit for monitoring a pulse train, e.g. to sense when a shaft has run up to its correct speed, comprises a cyclic counter 5 driven continuously by a clock pulse generator 6, the counter 5 giving an output pulse at 8 whenever it reaches a predetermined count, and being reset to zero by each pulse of the pulse train being monitored, a first toggle 7 set by a pulse from the counter output terminal 8 and cleared by each pulse of the pulse train, and a second toggle 10 set by a second pulse from the counter output terminal 8 when the counter has not been reset by a pulse of the pulse train between said second pulse and the preceding first pulse from the counter, and cleared by the coincidence of the first toggle 7 in its cleared condition with a pulse of the pulse train, which cleared condition of the second toggle 10 indicates that the repetition rate of the pulse train is up to the correct speed. As shown, the shaft carries a disc 1 having markings or teeth to be detected by a photo-electric or magnetic sensor 2 which produces an output as each mark or tooth passes to cause a pulse generator 3 to produce a pulse. The markings or teeth have a gap at at least one part of the disc 1 to provide a regular datum gap in the pulse train from the generator 3. The output lines from the toggle 7 pass via delay elements 12, 13 respectively to AND gates 9, 14 and thence to the toggle 10. When the counter 5 reaches a second predetermined count greater than the first, the datum gap in the pulse train being great enough to allow this second count to be reached when the pulse train is not below its correct speed, the counter produces a pulse in a line 16 to an AND gate 15 between the toggle 10 and a third toggle 11. The third toggle 11 is set by the occurrence of two consecutive pulses from the counter output terminal 8, as detailed above, and is cleared by the coincidence of the second toggle 10 in its cleared condition with the occurrence of a pulse from the counter output terminal 16. The third toggle, when set, inhibits actions not to be performed while the shaft is below speed, and when cleared enables these actions to be performed in correct timing with respect to the shaft rotation.

It differs from bovine PTH at positions 1, 7, 16, 22, 28 and 30, and from percine PTH at positions 16, 18, 22, 28 and 30. The peptide may be prepared by covalently attaching N-protected phenylalanine to an insoluble support comprising 1% cross-linked chloromethylated polystyrene beads; deprotecting the phenylalanine; condensing N-protected asparagine with the phenylalanine; deprotecting the asparagine; successively condensing each of the N-protected amino acids corresponding to the residues of the peptide and deprotecting the condensed amino acids, thereby to form a support-coupled peptide; and then removing the peptide from the support. Each amino acid is N-protected with a t-butyloxycarbonyl group and the deprotecting steps are performed with trifluoroacetic acid in methylene chloride. Each condensation is performed in the presence of dicyclohexyl carbodiimide in methylene chloride and the peptide is removed from the support with liquid hydrogen fluoride. Alternatively, the peptide may be produced by condensing, according to a defined procedure, intermediate products prepared by standard methods.

Abstract: 698,933. Calendars. MALCOLM, W., and MARTON, R. J. March 15, 1952, No. 6763/52. Class 106 (iv). A perpetual calendar comprises a month-day table C having a plurality of panels arranged in rows and columns and each including a month and corresponding day name; and a monthly calendar D bearing month numbers arranged in rows and columns. As shown, Fig. 1, the month-day table C and a "year commencement " table B are mounted on a support A in a frame 14, while the calendar D is slidable on a rod 8 over the lower part of the support A. Each column of the table B is headed by a day name which signifies that each year in that column began or will begin on that day. In use the monthly calendar D is set so that the " first" falls under the panel bearing the month January " and the appropriate day name for January 1st of the required year, whereupon the day of the week corresponding to any date in the year may be read in the twelve rows and seven columns immediately above the monthly calendar D provided the year is not a leap year. If it is leap year the monthly calendar D must be moved one space to the right at the end of the 29th February. An indicating guide E is slidable and rockable on the rod 8, its movement being limited by a stop 18<SP>1</SP> and notch 19 co-operating with hinge knuckles at the ends of the guide.

Title: Measuring Reactance
IPC: G01R27/02
Filed: 1978-12-11
Abstract: Current from a second circuit is balanced by current from a third circuit energised by a voltage dependent upon the current flowing in a first circuit, whereby the value of one reactance in either the first or third circuit can be determined from the values of components in the other circuits using the balance equation. In a first embodiment, the first circuit comprises a resistor R3, Fig. 5, and a capacitor Cx to be measured, the second comprises a resistor R2, both circuits being energised by a supply S1, and the current in the second circuit is opposed, in a tapped choke, by the current from a third circuit, comprising a standard capacitor C8, energised by a voltage, from an amplifier A, dependent upon the current in the first circuit. In a second embodiment (Fig. 6, not shown), the unknown and standard capacitors are effectively interchanged. Inductance can be measured similarly (Figs. 4 and 7, not shown), and when the unknown reactance is in the third circuit the zeroising resistor Gc, Fig. 5, can effectively be replaced by an additional amplifier and a coupling transformer (Figs. 7 and 8, not shown). <IMAGE>
