Title: Improvements in and relating to rail vehicles, and, more particularly, to passenger carriages
IPC: B60F1/04
Filed: 1932-11-25
Abstract: 401,119. Railway vehicles. RIMAILHO, E., 83, Avenue Foch, Paris. Nov. 25, 1932, No. 33457. Convention date, Dec. 3, 1931. [Class 103 (vi).] In a motor-driven or other rail vehicle the different frames or elements, such as the floor and the underframe, are supported on independently and separate spring wheel sets and are permitted a relative movement in a vertical direction only, while all the wheels run on the same pair of rails. Means may be provided for varying manually or automatically the distribution of load between the sets of wheels, and also for permitting certain of the axles to move laterally to facilitate the negotiation of curves. According to the construction shown in Fig. 1, the floor 6 and seating 7 are mounted on pneumatic or like resiliently tyred wheels 12 for minimizing shocks communicated to the passengers, while the underframe 1, sides 15, and roof are supported on the ordinary flanged wheels 2 for guiding purposes. The floor 6 is constrained to move vertically relatively to the body 15 by guides comprising rods, segments or rollers, while quadrilateral linkages 13, 14 are disposed between the floor and underframe to ensure the longitudinal and lateral connection of these parts. In order to vary the distribution of load between the sets of wheels screw-threaded rods 17, Fig. 2, capable of hand adjustment may pass through members of the underframe and bear with the required pressure upon leaf springs 19 mounted between posts 8 depending from the floor 6. Such an arrangement is useful in particular when the wheels 12 are the driving-wheels, and it is desired to increase the adhesion thereof, e.g. when the carriage is running empty. According to other arrangements the transfer of load may be accomplished by pneumatic means acting on the floor and underframe with, if desired, in addition, an automatic control for preventing the load on the pneumatic wheels from exceeding a predetermined maximum. When the vehicles are intended for road use also, the wheels 2 are replaced by suitable road wheels. In the above-described constructions, when the vehicle is traversing a curve, the wheels 12 slide laterally across the rails, but these wheels may also be provided with flanges 12a as shown in Fig. 8, by permitting the axle 10 a lateral movement. This result is attained by connecting, through the medium of rods 46 with ball-joints 46a at both ends, the axle casing 42 to a transverse member 44 that is guided vertically in horn-plates 45. Centralizing springs acting in a direction parallel to the axle 10 may be incorporated for restoring the latter to its normal position.

Patent GB-491415-A (GB)
Title: Improvements in or relating to processes for improving the compressibility of metal powders
IPC: C22C33/02
Filed: 1937-12-07
Abstract: The compressibility of quantities of powder which contain harder and softer metals is improved by using the soft metals in the form of a powder the volumetric weight of which is smaller than the volumetric weight of the harder metal powder used. Preferably a powder of softer metal is used of which the volumetric weight is roughly half or less than half of the volumetric weight of the harder metal.  By "volumetric weight" is meant the weight of that amount of powder which, loosely poured out and shaken to a constant volume is present in unit volume.  In examples, iron powder of which 3,3 gr. occupies 1 cc. may be mixed with copper powder, of which 2 gr. or preferably 1,4 gr. occupies 1 cc.  The mixtures may contain 90 per cent iron, 10 per cent copper, of 80 per cent iron, 20 per cent copper.  Components may also be added for hardening purposes.  Antimony arsenic silicon phosphorus or sulphur may be employed for that purpose preferably in the form of pre-alloys such as phosphor-copper. These pre-alloys can be produced with both the softer and harder metals.  When the softer metals are used as components of the pre-alloys only a portion of the softer metal of the mixture is used to form the pre-alloy. Oil-porous machine parts such as bearings and journals may be made by compressing and sintering suitable mixtures, such as, for example, a powder containing 20 per cent copper, 2 per cent antimony, 2 per cent graphite and the rest iron.

Abstract: 1,122,472. Protective arrangements. FUJITSU Ltd. 10 Aug., 1965 [10 Aug., 1964], No. 34264/65. Heading H2K. [Also in Division G4] In a system for testing the components of a logic circuit, if a component is defective the entire logic circuit is blocked by an appropriate voltage signal. In the embodiment described each of a plurality of logic circuits e.g. delay line DL1 (Fig. 3) and series connected bistable devices F11-F13 are connected to a tester circuit e.g. TST1 and also to decoder circuits e.g. DEC1 so that in normal operation signals fed by the delay line are decoded. Periodically test signals from a test pattern generator TP in the tester circuit TST1 are supplied both to the delay line DL1 and also to AND gates G10, G11, the output signals from the last of the series of bistables i.e. FF13 also being fed to the gates together with clock pulses on line 12. If, when a "1" signal from the pattern generator TP is transmitted, one of the AND gates is enabled, indicating that one of the components is not operating correctly, a relay R1 is energized and associated switches r 1 , r 2  and r 3  operate, the first resulting in the circuit components DL1, F11-F13 being held in their "1" state, the outputs from the latter are also supplied to check circuits CK1-CK4 (common to all the logic circuits) that determine whether the correct outputs have been received from the components. In the event of error no output signal is obtained from the associated check circuit. The check circuits are connected to AND gates G5-G8 sequentially enabled so that any component not functioning may be determined. The AND gates are connected via an OR gate G9, inverter IV press button switches S2, S<SP>1</SP>2 and relay contacts r 3 , r 3 <SP>1</SP> to the delay lines so that when the component in the malfunctioning logic circuit has been replaced, the associated switch 52, 52<SP>1</SP> may be pressed and the "1" signal from inverter IV when the next clock pulse is transmitted results in all the components being unblocked.
