A railway vehicle bogie comprises a pair of wheel and axle assemblies 1, 2, Fig. 1, separate relatively-movable longitudinally-extending side frames 5 supported on axle boxes (3), Fig. 2 (not shown), coil springs (23) carried by the side frames intermediate of the assemblies, a transverse bolster (29), Fig. 3 (not shown), supported at its end portions on the springs (23), and a pair of parallel substantially longitudinally extending transversely spaced anchors 49 at each side of the bogie, one end of each of the anchors being connected to the adjacent side frame and the other end of each of the anchors being connected to the bolster. The anchors 49 at each side of the bogie are connected to bracket webs 35, 37 on the associated side frame 5 and vertical webs 41, 45 on the bolster. Each anchor (49), Fig. 6 (not shown), comprises a rod (51) passing apertures (53) in the associated webs, e.g. (35), (41) and surrounded by a spacer sleeve (57) between the webs (25), (41). The ends of the sleeve are provided with hemispherical collars (59) whilst the ends of the rod have secured thereto similar collars (61). Between the collars and the ribs are disposed rubber masses (55) which are undercut at (56) where they engage convex surfaces of the ribs (35), (41) around the apertures (53) therein. The rubber members also extend into the apertures. The anchor assembly is secured together by nuts (63) on the rod ends and the rubber members placed under compression. Longitudinal deflection of the rubber members is strongly resisted whilst lateral and vertical deflection is readily permitted and the anchors maintain the bolster at right angles to the side frames irrespective of the lateral or vertical movements of the bolster. The bolster, Fig. 3 (not shown), has depressions to permit passage thereover of the inward anchors 49. The bolster also has a central cylindrical recess (67) to receive a depending cylindrical projection (75) on the body (B) of the railway which, with the interpositioning of a friction liner (73). The recess and projection are surrounded by annular flat surfaces (69) and (77) on the bolster and body, and a friction annulus (71) is interposed between the flat surfaces. Lateral movements of the bolster are limited by stop members (66a) and (66b) thereon. The width of the bolster is substantially less than the width of the windows in the side frames and is snubbed by wedges (62), Fig. 2 (not shown), under the urge of springs (65). The surface of each wedge adjacent the bolster is crowned.

Filed: 1971-08-13
Abstract: 1355841 Transistor amplifiers RCA CORPORATION 13 Aug 1971 [14 Aug 1970] 38081/71 Heading H3T  An amplifier is not responsive to a large input voltage charge (52, Fig. 4c, not shown) but responds to a small signal superimposed thereon (e.g. at time t 3 ). It consists of a transistor Q1 receiving the input at its base, having a clamping diode D<SP>1</SP> in its collector output circuit, having a constant current source (such as Q3 together with Q1) arranged to give a substantially steady output voltage to comparator 30, and having a capacitor C<SP>1</SP> connected to its emitter. R1 and R6 are dimensioned to give the required steady output voltage, such as zero. When the large negative excursion (52) of the input occurs, a large current (54, Fig. 4d, not shown) flows from C<SP>1</SP>, but the output voltage is clamped by D<SP>1</SP> close to earth. When the input voltage becomes steady at the new level, C<SP>1</SP> having now charged to its new voltage, both Q1 and Q3 become operative to again supply the said constant current through R1 and R6 so that the output is still virtually zero. When a small positive signal occurs at the input (t 3 ), Q1 amplifies and inverts this to give a negative signal (62, 4e) at the output to 30. A similar complementary circuit, using opposite type transistors Q2, Q4, provides a complementary signal to the other input of 30 whose output is then an amplified form of the information signal, irrespective of the large voltage on which it is superimposed. The circuit is used to amplify read-out pulses from a magnetic memory. The earth connections in the middle of Fig. 2 may be omitted and the capacitors C<SP>1</SP> resistors R<SP>1</SP>, and diodes D<SP>1</SP> replaced by a single capacitor C, resistor R, and diode D (Fig. 1, not shown).
