Title: A Pulse Generating Circuit Arangement.
Inventor: SMITH CARLYLE FITZGERALD
IPC: H03K3/30
Filed: 1966-10-12
Abstract: 1,199,409. Transfluxor circuits; transistor pulse - generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 26 Sept., 1967 [12 Oct., 1966], No.45556/66. Headings H3B and H3T. A pulse-generating circuit comprises a transfluxor and a transformer in the feedback paths of a pair of transistors arranged in push-pull. Transfluxor 1 is first blocked by a pulse on blocking winding 7 and then set by a pulse on winding 6 which pulse causes starting transistor 21 to conduct and energize auxiliary starting winding 24. Due to the change in flux around aperture 5 when the transfluxor is switched from a blocked to a set condition and the current pulse in winding 24 one of the transistors 11, 12 is rendered conductive. If transistor 11 conducts current flows in primary winding 14 and induces a current into feedback winding 15 of transformer 13 which depending on its polarity energizes either winding 8 or 9 wound on the transfluxor. This current in winding 8 or 9 maintains a current in output winding 10 to keep transistor 11 bottomed and transistor 12 cut off until the flux around aperture 5 reaches saturation. When this occurs transistor 11 is rendered non- conducting, the flux in transformer 13 collapses causing a reversal of current in the feedback winding 15 and the switching on of transistor 12. Transistor 12 remains conducting as long as the region of the transfluxor linked by windings 8, 9 is not saturated when the process is repeated. An alternating pulse output is obtained from windings 19 and 20. Diodes 17 18 may be omitted and the feedback winding may be connected to a single input winding on the transfluxor in which case one cycle of the alternating current would act as a driving pulse and the other as a priming pulse.

In Fig. 1 electric analogue apparatus correcting the proportions Cm and Wm in a concrete mix for variations of cement quality receives voltages at terminals I 1 , I 2  representing Cm, at I 2 , I 3  representing Wm, and at I 4 , I 5  representing gravel; all in a reference mix; derived from the apparatus of Specification 1,193,651. From Bolemey's formula # = K(C/W-0À5) where# is crush strength K is constant for cement quality C is weight of cement W is weight of water it is shown that for equal strengths of reference and test mixtures, Cna = (Km/Kcn) (Cm - 0À5W) + 0À5W for weights Cna = (Km/Kcn) (Cm - 0.159W) + 0À159W for volumes, with cement of s.g. 3À15 where Km, Cn are constants of quality of reference and test cements, and Cm and Cna are cement quantities in reference and test mixtures. R 1  and R 2  are proportioned to develop voltage between 1 1  and junction a representing Cm - 0À159W, and halved by R<SP>1</SP>3, R<SP>11</SP> 3  to derive voltage representing (Cm - 0.159W)/2 at positive input of differential amplifier OA, with at negative input a feedback voltage representing Km/Kcn of the amplifier output derived from manually set potentiometer Ra. Then voltage across terminals O<SP>1</SP>c, 0<SP>11</SP>c represents Cna the volume quantity of test cement required for equal strength, across terminals O<SP>1</SP>w, O<SP>11</SP>w represents the volume quantity Wm of water required, and across O<SP>1</SP>G, O<SP>11</SP>G the volume quantity of gravel required. In a modification (Fig. 2, not shown) a further differential amplifier having inputs receiving voltages representing Cm and Cna, and also the quantity of gravel G, produces an output voltage G 1  = Cm - Cna + G, so that the gravel content of the mixture is compensated for a greater or less cement content, for constant volume. The apparatus is applicable to batch mixtures other than concrete.
