Abstract: 1,204,980. Pulse modulation circuit.; transistor monostable circuits. P. R. MALLORY & CO. Inc. 8 Nov., 1967, No. 50487/69. Headings H3T and H4L. In a pulse-width modulator the duty cycle of a monostable device comprising transistors T11, T12 is varied by an input signal applied at terminal 50 while the repetition rate as controlled by frequency negative-going pulses pulses applied at terminal 41 remains constant. The output is supplied via amplifiers 30 comprising complementary transistors T31, T33 and T32, T34, respectively, and charging current for the timing capacitor C11 is supplied via the low saturation resistance of transistor T31 and diode D11, enabling a higher repetition rate to be used. Transistors T21, T23 act as constant current devices.

Abstract: 1292330 Decorative polyurethane coatings TEXTRON Inc 22 Oct 1969 [30 Oct 1968 (2)] 51704/69 Heading B2E A decorative coating is applied to a solid substrate by coating the substrate with a liquid polyurethane composition, distributing over the coating, while it is not cured beyond the tacky stage, particles of coloured inert solids containing a curing aid for the polyurethane, the solids being at least partially exposed beyond the coating, applying a further layer of a clear liquid polyurethane composition and allowing the polyurethane compositions to cure. The curing aid may be a material capable of promoting the curing of the polyurethane catalytically or may be a polyfunctional material which is reactive with the partially cured polyurethane, such as a compound containing amino or hydnoxyl groups. Suitably the polyurethane compositions are moisturecuring and the curing aid is a catalyst for the moisture-curing reaction. The particles which may be organic or inorganic may be admixed with an organic or inorganic binding agent. The polyurethanes which may be liquid per se or in solution are preferably derived from a polyol of the formula where R' is an aliphatic hydrocarbon radical, R" is an alkylene radical of 2 to 4 carbon atoms, n is from 0 to 50 and m is 0 to 2 many such polyols being listed.

In operation a pump diaphragm 20 supplies fuel via filter 24, passage 28 and valve 30 to chamber 42. When throttle 56 is wide open check valve flap 94 closes opening 72 and when the throttle is closed the flap closes opening 104 to prevent fuel blow back from the mixing passage through the idle passages which are fed from chamber 42 via passages 62, Fig. 5, 66 and 54. Passages 58, 60 may serve as air inlets for the idle mixture in the closed throttle position. When the throttle is being moved from the closed to the open position the flap 94 occupies an intermediate position in which both flow paths are fed with fuel from a reserve supply of fuel in the chamber 82 thereby assisting engine acceleration.

[Also in Division F2] A method of making a concrete pipe comprises the steps of stress-relieving a continuously-fed cold-drawn reinforcing wire, bending the wire into a circular helix, cutting the helix to length to form a reinforcement which when freely suspended assumes a circular cylindric shape, and then suspending the helix in a mould and pouring concrete around it. The apparatus comprises a gyratory straightener A having jaws through which the wire is drawn by feed rolls 3, and a three-roll bending device comprising a positionally fixed driven upper roll and two adjustable lower rolls 5. The rolls 5 are adjusted by the handle 6 to vary the radius to which the wire is curved. The wire then passes between pairs of driven guide rollers 7 and 8. The driven rollers of the apparatus are rotated at infinitely variable speeds. When sufficient turns of the helix have been formed, the wire is cut by a flying shear 9, the cutter assembly of which travels in a circular arc concentric with the helix of wire. A modified apparatus includes, between the straightener A and the bending device B, a storage drum (D), Fig. 3 (not shown), a roller straightener (E) and an induction furnace (F). The Specification also states that the degree of bending can be continuously varied automatically, to compensate for lack of uniformity in the wire, by first measuring the bending resistance of the wire, converting the resistance so measured to an electrical signal and using this signal to control the bending rollers which, in this case, are hydraulically operated.
