Abstract: 1,083,390. Pulse modulation circuits; transistor multivibrators. BUNKER-RAMO CORPORATION. Nov. 26, 1965 [Nov. 27, 1964], No. 50423/65. Headings H3T and H4L. The output of a multivibrator is caused to vary over a wide frequency range by the application of a control voltage. The device is described in relation to the numerical control of machine tools and the like. As shown, the free-running multivibrator comprises transistors Q 1 , Q 2 , additional current gain to maintain oscillation at the higher frequencies being provided by complemented emitter follower circuits Q 3 , Q 4  and Q 5 , Q 6 . Associated with capacitors 18, 20 forming part of the respective charging circuits of the multi-vibrator are transistors Q 7 , Q 8  controlled by the input voltage at 10 to vary the time constant of the charging circuits and thus the operating frequency of the multivibrator. A transistor Q 9  is connected in the emitter circuit of transistors Q 7 , Q 8  and normally is forward biased by the output of the multivibrator rectified at D 2 . If oscillations should stop or fail to start, the transistor Q 9  is back-biased, cutting off transistors Q 7 , Q 8  and allowing transistors Q 1 , Q 2  to come out of saturation so that oscillation can begin.

Abstract: 1,255,690. Microwave heating apparatus; aerials. CANADIAN PATENTS & DEVELOPMENT Ltd. 20 Oct., 1969 [21 Oct., 1968], No. 51336/69. Headings H4A and H5H. The proportion of energy which is available for useful work is varied along the length of a waveguide by means of a ridge or ridges. Thus, the rectangular waveguide 10 is provided with two pairs of ridges 14, 15 and 16, 17 between which the electric field is concentrated. The presence of the ridges produces a decreased intensity in the vicinity of a workpiece 13 (e.g. a tube containing material to be heated or a set of axially aligned radiating slots). The ridges may be tapered to obtain a longitudinal variation in distribution of the field, e.g. in order to compensate for attentuation and to obtain uniform heating or radiation. The tapering may be linear or curvilinear. This effect may also be achieved by means of graded dielectric loading near the narrow sides of the waveguide. The Specification also describes an elliptical waveguide with two pairs of ridges (Fig. 5, not shown) and a rectangular waveguide with more than two pairs of ridges. The workpiece may consist of a lamina moving through longitudinal slots in the waveguide in a direction parallel with the narrow sides. Alternatively, the workpiece may move parallel to the axis of the guide and be so arranged that the parts to be heated are located between the opposed ridges. Where the waveguide is used as an aerial, the ridges are stated to have the effect of reducing side lobes.

The member 1 may be a straight rod, wire or tube having a cylindrical outer surface or may be of thin thickness material.

[Also in Division H3]  In a magnetic core shift register each stage k-1, k etc. comprises four cores arranged in two substages n-2, n-1, &c., each substage consisting of two cores A and B. Shift pulses a, b are applied alternately to the substages. A substage registers " 1 " when both its cores A, B are in the " 1 " state. To effect a transfer of this " 1 " to the next substage a resetting pulse c is effective to reset the core A to " 0 ". The next shift pulse resets the core B to " 0 " thus inducing a pulse in a 3-turn winding N 1  effective over a connection such as S n  to switch both cores A, B of the next substage to " 1 " via 1-turn windings N 2 . An over-transfer is prevented since oppositely wound windings N 1  on the cores A, B receiving transfer produce pulses which cancel. A back transfer is prevented since a pulse induced in a 1-turn winding N 3  on the core A receiving transfer cancels a pulse induced in the winding N 2  of the core B being switched by the shift pulse.
