Title: Apparatus for detecting the orientation of the plane of polarisation of a linearly polarized beam of radiation
IPC: G01J4/04
Filed: 1968-11-28
Abstract: 1,248,752. Light modulators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 Nov., 1968 [1 Dec., 1967], No. 56573/68. Heading H4F. [Also in Division C1] Measurement of the fixed or slowly varying plane of polarization of a beam of radiation is facilitated by applying a periodic polarization variation, using at least three doubly refracting elements, at least one of which is electro-optic. A plane polarized beam, e.g. from a saccharimeter is collimated at 2, Fig. 1, and applied to a polarization modulator comprising #/4 plates 4, 6 and a KDP Pockels cell 5 fed from a sinusoidal voltage source 10. A KTN cell may be used instead of the KDP cell and arranged to have a substantially linear retardation against voltage characteristic by making the modulating voltage small compared with a simultaneously applied direct voltage. The oscillating plane polarized light emerging from #/4 plate 6 is split by a semi-transparent plate 20 and passes through analyzers 21, 22 mutually at 45 degrees to photo-detectors 33, 34 producing quadrature signals. These signals are multiplied in Hall generators by voltages synchronized with the sinusoidal modulating voltage and the modulating frequency is eliminated by filters to give signals proportional to sin 2a and cos 2a where a is the polarization angle of the radiation to be measured. Simpler detector circuitry may be used if a sawtooth voltage is used instead of the sinusoidal voltage 10. Another way of producing substantially sawtooth modulation is to use an odd number (e.g. three) of electro-optical KDP cells, Fig. 5 (not shown), the odd and even numbered cells being energized in quadrature. The electrooptical cells may be made up of a number of component cells with a proportionate amount of the operating voltage across each.

Abstract: 1,247,352. Heat treatment of aluminium alloys. ALCAN RESEARCH & DEVELOPMENT Ltd. Nov.28, 1968 [Dec. 5, 1967], No. 56626/68. Heading C7N. An article fabricated of a heat-treatable Al alloy and of indeterminate length is heat-treated by: (a) advancing the article through the heating region of a heating furnace so that any given point on the article has a dwell in the heating region of not more than two minutes, exposing the article in said region to a heated fluid above the temperature to be attained by the article, the final temperature of the article causing complete solid solution of hardeners in the alloy, and (b) quenching the article in a quenching medium as soon as it leaves the heating zone. The heating and cooling fluids are usually gases but liquids are used. If alloy strip is the article to be treated it should preferably not exceed a gauge of 2À5 mm. Alloys suitable for treatment in accordance with the invention include Al-Mg-Zn, alloys with Mg 2 Si and Al clad alloys. Typically strip is fed under low continuous tension through a heating zone of 3-14 metres in length, and heating and cooling are effected by directing jets of heated and cooled gas respectively on to the surface of the strip so that the strip in effect floats on these jets. One or more heating zones may be provided before the quenching zone.

Title: Standby cardiac pacer
IPC: A61N1/365
Filed: 1966-12-20
Abstract: 1,149,559. Cardiac pacer apparatus. COR DIS CORP. 20 Dec., 1966 [6 May, 1966], No. 56865/66. Heading A5R [Also in Division H3] A cardiac pacer comprises a ventricle electrode connected to a source of electric stimulating pulses with an interpulse interval conformable to the normal heart beat rate, means under the control of a sensed physiological signal and acting upon said source for inhibiting the delivery of the pulses throughout a period at least equal to said interval and commencing with the sensing of said signal, and blocking means which is actuated both by a pulse delivered as a stimulus to the ventricle and by a natural physiologic signal originating in the ventricle for preventing a sensed physiologic signal from acting upon the source until after the termination of a simulated refractory period following the delivery of the stimulus. As shown, a free running multivibrator with transistors Q 6 , Q 7  provides stimulating pulses (A, Figure 2, not shown) at a resistor R 16  which are then supplied via a transistor Q 8  and resistor R 22  to the ventricle electrode 1. The multivibrator provides a pulse when a charge on a condenser C 8  derived from the battery B 1-5  leaks away. The circuit is also arranged to amplify, through transistors Q 1 , Q 2 , a QRS cardiac signal from the electrode 1 and to pass this signal to a monostable multivibrator including transistors O 3 , Q 4 , this signal causing the monostable multivibrator to change to its metastable state and be insensitive to further signals for a period corresponding to the refractory period of the heart. The monostate multivibrator, in changing to its metastable state, also provides a pulse through a capacitor C 6  to control switches S 1 , S 2 , which then connect the condenser C 8  to a battery B 6  so that the condenser is recharged and the pulses from the multivibrator are delayed and retimed. An alternative circuit (Figure 3, not shown) similar to that described above but without the auxiliary battery B 6  is retimed to a QRS signal from the electrode 1 by arranging that this signal advances the pulses of the multivibrator Q 6 , Q;, the first advanced pulse then being blocked by a transistor Q 5 . Since stimulating pulses are fed back into the amplifier Q 1 , Q 2 , a further transistor Q 9  is arranged to disable the transistor O 5  during the provision of stimulating pulses from the multivibrator Q 6 , Q 7  when QRS signals are absent. In a second alternative circuit (Figure 4, not shown), similar to that of the first alternative, the monostable multivibrator Q 3 , Q 4  can only be triggered by a positive pulse and is sensitive to only the trailing edge of a stimulating pulse fed back from the multivibrator Q 6 , Q 7  and the resultant pulse from the changing multivibrator O 3 , Q 4  is arranged to be ineffective to alter the free running multivibrator Q 6 , Q 7 .
