Title: Light beam polarization modulator
IPC: G02F1/03
Filed: 1971-07-12
Abstract: 1363885 Modulating light WESTING- HOUSE ELECTRIC CORP 12 July 1971 [17 Aug 1970] 32520/71 Heading H4F A birefringent crystal 2 divides an incident plane, circularly or elliptically polarized beam 1 into parallel E and O rays 8, 7, which are passed through respective birefringent crystals 11, 10, a #/2 plate 9 and are recombined by a birefringent crystal 3 complementary to crystal 2. Plate 9 serves to render the two path lengths equal so that the recombined beam 1<SP>1</SP> normally has the same polarization as beam 1. When an electric field is applied along the Z axis of at least one of the crystals 10, 11, (i.e. orthogonal to the optical path and at 0 or 90 degrees to the incident polarization vector) the optical path lengths become unequal due to the changes in refractive index and the polarization of beam 1<SP>1</SP> is altered. As particularly described, a beam 1 plane polarized at 45 degrees to the optic axes of crystal 2 may be switched to a beam 1<SP>1</SP> plane polarized at 135 degrees to the optic axes if crystals 10, 11 provide a #/2 path difference when actuated and passed or blocked by an analyser 12.

Title: Improvements in or relating to car couplers
IPC: B61G3/04
Filed: 1936-12-02
Abstract: 486,443. Couplings and draw - gear for railway vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO. Dec. 2, 1936, No. 33079. Convention date, Dec. 5, 1935. [Class 103 (v)] In order substantially to eliminate train slack in a train employing knuckle couplers, the knuckles 167 of the couplers are constructed so that they interlock each with its front face 168, Fig. 16, in contact with the recessed or buffing face of the opposed head, thus providing a tight coupler in which angling between the heads is obviated but the necessary angling movements are provided for in the mounting of the coupler shanks. In order to guide the knuckles into correct engagement, the coupler-heads are furnished with co-operating lateral projections 175 and recesses 173 having inclined guiding surfaces. The knuckle is firmly locked in its locking position by means of a gravity lock 238, Fig. 31, having an inclined surface 239 which coacts with a corresponding incline on the knuckle tail 236, the lock being thus wedged against the opposite wall 246 of the coupler recess. The lock is also provided with an anti-creep projection 247 adapted to engage a shoulder 250 on the coupler-head. Provision for both vertical and horizontal angling may be effected by arranging at the rear end of the coupler shank 28, Fig. 5, a radial butt piece 44 having a curved surface 38 bearing against a corresponding curved surface on a follower block 23 at the forward,end of the buffing and draught gear 22. For centralizing the shank 28, the same may be supported on a carrier plate 33, Fig. 10, displaceable vertically on bolts 70 against the effort of springs 83, while lateral displacement is restrained by spring- pressed plungers 93. In a modification, suitable for passenger service, where a smaller degree of vertical angling is required, the same may be provided for at the pivot of the coupler shank. During a transition period the couplers are adapted to lock either with the standard couplers or with couplers having the knuckles shaped so as to provide a semi-tight engagement.

In a fluid-pressure regulator comprising a casing having inlet and outlet passages 12, 14 therein intersected by a valve seat 26 which communicates with a chamber 32 formed in the valve bonnet 28, a valve member 46 is axially guided by the bonnet and is biased to the open position by a spring 58, and a diaphragm chamber 100 mounted on top of the bonnet communicates via a bore 108 with the outlet passage so that increased outlet pressure acting on a diaphragm 82 mounted therein which is connected to the end of the valve stem urges the valve member towards its seating against the action of the spring 58. The valve stem and chamber 32 are sealed by a cup-shaped member 122 with a central sleeve 124 which fits around the valve stem and a flange 126 which fits in a recess in the casing to form a seal with the bonnet. The tension of spring 58 may be adjusted by a number of screws 78 (one shown), and a screw 72 limits the maximum opening of the valve.

Fixed-chamber apparatus; valve systems for; with counting-apparatus.-Liquid stored in a tank under pressure of an inert gas is delivered to a measuring vessel and a valve is arranged between the vessel and a three-way cock controlling admission to and discharge from the vessel in such manner as to prevent the full pressure from being transmitted to the measuring vessel. The three-way cock 3 is connected by a conduit to the measuring chamber 1 provided with a vent v, the coonduit being fitted with a valve 5 acted upon by a spring 6 which tends to close it. The spindle 7 of the valve extends through a fitting 13 and, when the valve is closed, extends also through the forked end of a lever 11 pivoted to the part 13. The other end of the lever is connected to a rod 9 depending from a float 10. A rod 18,' the head 19 of which works with play in a recess 20 in the body of the valve 5, is worked by an eccentric 16 on the spindle 15 of the cock. In the position shown, the vessel is full, the valve 5 closed, and the head 19 of the rod 18 in its highest position. To discharge, the cock is turned to the other position, the rod 18 opening the. valve 5, and the float 10 falls until the rod 9 engages the bottom of the chamber, rocking the lever 11 and bringing a knife 14, which extends across the fork of the lever 11, over the end of the valve-spindle 7 to lock the valve in the open position. When the vessel is empty, the cock is turned to filling position again, the rod 18 moving upwards, but the valve 5 remaining open. At the end of the filling operation, the float frees the valve 5 which is closed by its spring. Counting mechanism may be operated from the spindle of the cock 3.
