Title: Non-reciprocal optical device
IPC: G02F1/03
Filed: 1966-09-30
Abstract: 1,121,037. Light modulators. WESTING- HOUSE ELECTRIC CORP. 30 Sept., 1966 [4 Nov., 1965], No. 43810/66. Heading H4F. The invention relates to an electro-optic light modulating device of the type described in Specification 1,066,612, wherein the D.C. electric fields are replaced by a microwave electric field. The device comprises a pair of electro-optic uniaxial birefringent crystals 10 and 11, Fig. 2, supported within a travelling microwave structure having two rectangular sections 20 and 21 adapted to propagate a TE 10  mode separated by a 90 degrees transition section 22, such that the microwave electric field E vectors 5 and 6 are perpendicular to each other and to the light path and parallel to the respective optic axes of the crystals. When positioned between crossed polarizers and the microwave electric field vectors are equivalent to a half-wave voltage, the system will only transmit light propagated in the direction in which the microwave field is travelling, i.e. the system is non- reciprocal. The microwave structure is designed to yield a microwave phase velocity in the electro-optic crystals which equals the velocity of the optical beam in the crystals and the crystals are chosen to have a length equal to one-half wavelength of the dominant microwave mode. Switch 26 determines the direction of propagation of the microwave energy from source 24 through the waveguide and thus the direction in which a light beam can pass. If the light beam is propagated in the opposite direction to the microwave energy its plane of polarization is not affected.

Abstract: 1,160,264. Valves. DOWTY TECHNICAL DEVELOPMENTS Ltd. 7 Oct., 1966 [19 Oct., 1965], No. 44145/65. Heading F2V. [Also in Division F1] The slide valve is biased to neutral by a spring 28 and controls the supply of pressure fluid selectively to opposed ends of a jack 5 from an inlet 34 through service points 47, 50. These ports are exhausted into the chamber 52<SP>1</SP>. One or more of these valves (19-24), Fig. 1 (not shown), are bolted together with interposed complementary casing parts (12-18) having common inlet and exhaust connections (31, 32). The casing includes one section (12) which houses a by-pass valve (39) Fig. 3 (not shown) connecting the inlet (31) directly with an exhaust passage (44). The by-pass valve is operated by a lever 58 on a common shaft. This shaft carries an individual lever 56 for each slide, with a cam follower 54 engaging symmetrical cam surfaces 53 on the slide. With all the slides in neutral the by-pass valve is open. Operation of any slide closes the by-pass valve. The shape of the cam surfaces, in conjunction with a metering slot (39a) in the by-pass valve, ensures satisfactory inching characteristics.

Title: Improvements in or relating to pulse code modulation decoders
IPC: H03M1/00
Filed: 1962-11-23
Abstract: 952,720. Pulse code modulation circuits. WESTERN ELECTRIC CO. Inc. Nov. 23, 1962 [Nov. 28, 1961], No. 44321/62. Heading H4L. [Also in Division G4] A P.C.M. decoder for an n-digit code comprises 2<SP>n</SP> 1  current sources, means for connecting each of said sources to a common summing point, and circuitry responsive to the incoming digital code signal to operate the connecting means to connect to the common summing point the number of sources the sum of whose current is the analogue representation of the code. As described, the current sources provide currents of equal value but the decoder may be given a non-linear characteristic by arranging that the currents from each source differ in the required manner. The arrangement provides better accuracy than the conventional arrangement using n current sources which are related in binary manner. As shown, in a three-digit system pulse code signals D 1 , D 2 , D 3  are supplied in parallel form to leads 33, 32, 31, and seven equal current sources 34 to 40 are connected to a summing point 41. Each current source may be a voltage source and a resistor. To represent the number one, only the least significant digit D 3  is present and this pulse is supplied via OR gate 43 to connect source 34 to the point 41. For number two only D 2  is present and a pulse is supplied via OR gate 43 to connect source 34 to point 41 and via OR gate 44 to connect source 35 to point 41. With D2 and D3 present (three) sources 34 and 35 are connected as before, and source 36 is connected via AND gate 46 and OR gate 47. Thus each successive increase by one requires the addition of a further current source to the common output circuit until finally with an input D 1 , D 2  and D 3  all the current sources are connected to represent the maximum analogue level. In order to reduce the complexity of the logic circuitry when more than three or four binary digits are used, the three most significant digits may be decoded as described and the remaining digits decoded in conventional manner using binary weighted current sources. Specification 940,507 is referred to.
