Apparatus for checking that the duration of incoming pulses is within prescribed upper and lower limits comprises a first monostable circuit providing a delay equal to the lower of the prescribed limits and a second monostable circuit providing a delay equal to the upper of the prescribed limits the outputs of the first and second monostable circuits together with the incoming pulses are applied to first and second bi-stable circuits which respectively provide indications if the duration is greater than the upper limit or less than the lower limit. As shown, contacts PC are operated in response to the pulse train under observation so that negative pulses are fed via differentiating circuits C1, R6, C2, R7 to monostable circuits ML, MH which respectively delay the leading edge of each pulse by times equal to the prescribed lower and upper limits. The delayed pulses are respectively fed to bi-stable circuits BL, BH together with the incoming pulses which are passed via an emitter follower T3. The connections are arranged so that the conductive states of the transistors in the bi-stable circuits are unchanged unless a pulse is outside the prescribed limits when the appropriate relay L or H will be energized and remain energized until released by manually operated contacts KS1, KS2. The bi-stable circuits are reset by contacts KS3. Capacitors C5 are provided in each bi-stable circuit BL, BH to ensure that each circuit is in the appropriate conductive state when the apparatus is first energized. H4K. Automatic exchange equipment.-The apparatus may be used during a routining process to monitor the duration of reference pulses which are maintained in phase with test pulses transmitted over a junction.

Abstract: 1,168,427. Measuring co-ordinate positions electrically. LITTON INDUSTRIES Inc. March 28, 1968 [April 3, 1967], No. 15069/68. Heading G1N. Apparatus for determining the X, Y co-ordinates of a point on e. g. the surface 20 Fig. 2 of a CRT comprises a conductive-coated transparent membrane 14 located over a resistive-coated transparent glass plate 18, covering the face of the CRT, and fed with an X and Y voltage pattern, so that the voltage picked up by the membrane when it is depressed at a test point 22 to contact the glass plate are indicative of the X, Y coordinates of that point. The resistive-coating of glass plate 18 has a plurality of terminals 60-82 Fig. 5 round its circumference fed with sine and cosine voltages to form a rectangular co-ordinate system of equipotential lines. These voltages may be D. C., fed alternately to produce first the X co-ordinate system then the Y coordinate system, or they may be alternating voltages of different frequencies. The inner, conducting surfaces of the membrane 14 and glass 18 are hermetically sealed by gaskets. In a modification Fig. 6 (not shown), the contacting members each consist of an insulating membrane coated on the facing sides with a parallel grid of conducting lines, with the grids at right angles, fed alternately with voltages forming equi-spaced potential lines. In another modification Fig. 8 (not shown), a third membrane is located between the grid membranes, and is made separately conductive on each face to act as the leads for the X, Y voltages.

Title: Improvements in or relating to sliding clasp fasteners
IPC: A44B19/36
Filed: 1941-11-24
Abstract: 553,552. Sliding-clasp fasteners. GRANT, H. B., and LIGHTNING FASTENERS, Ltd. Nov. 24, 1941, No. 15126. [Class 44] In a sliding-clasp fastener which allows separation of the stringers when the slider is at the top end with the fastening closed, a top stop 6 is provided having a projection 7 which enters a groove 8 in the slider and is resiliently arrested therein to prevent further movement of the slider when normal force is applied thereto, the projection passing completely through and out of the groove when additional force is applied. As shown the groove 8 is formed in one wing 5 of the slider and a spring member 11 secured in an exterior recess in the wing by a riveted projection 13 has one end curled inwards to form a rounded projection extending inwards at 15 into the groove 8 to obstruct passage of projection 7. The spring yields when additional force is applied so that the slider can be moved past the stop. The tape bead 3 terminates above the stop and has a tag 16 or other means to prevent fraying. When the slider is moved beyond the tag 16 on to the unbeaded part of the tape, the tape can be removed laterally through the slot in the slider and the fastening released by lateral pull on the tapes. The slider is retained on the bead 3 of the other tape, which has a stop of usual form to prevent endlong removal of the slider therefrom or, as shown, is folded over at the end 17 and secured by stitching. Stops such as 6, 7 may be provided on both stringers and the slider provided with a corresponding pair of grooves, or the stop may have oppositely directed projections with corresponding grooves in both wings of the slider. In an alternative form the spring is omitted and the groove is of decreasing depth so that the projection 7 becomes wedged therein, resilience of the material of the slider being relied on to allow movement of the slider to be continued by application of sufficient force. The stringers have separable fittings, not shown, of the usual pin and socket type, at the lower ends.

Abstract: 1,039,785. Automatic control of electric motors. PARMEKO Ltd. April 20,1964 [April 20, 1963],No. 15662/63. Heading G3R. The speed of an electric motor M is controlled by a primary loop circuit comprising reference source PR, the motor current being limited to a value set by reference source SR in a subsidiary loop circuit. In the absence of the latter, the speed error signal at the junction of resistors R3, R5, is matched by that appearing at the junction of resistors R2, R4, and applied to a unity-gain, polarityinverting amplifier. Rectifier MR becomes conductive, the primary loop being rendered ineffective since the overall signal input to the regulator is zero. The primary loop is rendered effective by a negative signal from source SR, the blocking condition of rectifier MR ensuring that the subsidiary loop is rendered inoperative. When a high positive current feed-back signal over-rides the signal from source SR, the subsidiary loop is rendered effective, the speed feed-back signals being cancelled. The amplifier comprises transistors VT1, VT2, forming a long-tailed pair, the output from which is inverted and amplified by transistor VT3. Transistor VT4 acts as an emitter-follower providing low output impedance to rectifier MR, feed-back components comprising resistor Rf2 and capacitor Cf. In modifications the system is applied to a voltage regulator with over-riding current control, or a current regulator with overriding voltage control.

Title: Process for the separation of wax from wax-containing hydrocarbon mixtures
IPC: C10G73/06
Filed: 1937-06-08
Abstract: Hydrocarbon oils are freed from wax by using as de-waxing solvent pyridine or its homologues in anhydrous form.  Preferably dehydrated commercial pyridine of final boiling point 145 DEG  C. is used. Pyridine may be mixed with selective solvents such as nitrobenzene, aniline, or chloraniline.  After dewaxing, the oil containing pyridine may be treated with aqueous alkali as described in Specification 496,956, to obtain extract and raffinate fractions.  In an example, a wax-containing oil is dissolved at elevated temperature in 2 1/2 times its volume of anhydrous pyridine.  The solution is then chilled and the precipitated wax is removed by centrifuging, electrodeposition or preferably, filtration.  The wax is washed with cold pyridine and the washings added to the filtrate.  This is then treated with aqueous alkali to form raffinate, extract, and aqueous layers, which are then separated.  The pyridine is recovered from each layer by distillation whereby there is a first obtained a small amount of a distillate of pyridine and water as a constant boiling mixture, then the anhydrous pyridine fraction, leaving a residue of raffinate or extract.  The process may be applied to the removal of oil from wax cakes.
