Abstract: 1306193 Electric motors SIEMENS AG 11 May 1971 [12 May 1970] 14322/71 Heading H2A An electric motor is energized through an inverter 6 which is commutated in dependence on rotor position and is supplied with D.C. from a source 4 which is controllable such that the supply of D.C. may be interrupted during commutations of the inverter in the low speed range of the motor, there being a smoothing inductance 5 between the D.C. source and inverter and a thyristor 7 in parallel with the inductor so that during interruption of the D.C. supply, the current flowing through the inductor can flow through the thyristor. The source 4 is a 3-phase thyristor bridge rectifier which, during commutation of the inverter 6, is itself operated as an inverter to set up a reverse D.C. through inverter 6. Commutation is effected when the actual current flowing through inverter 6 is reduced to zero. After commutation, bridge network 4 is again fired as a rectifier, feeding D.C. to the inverter 6, the D.C. switching off thyristor 7.

Title: Detector for coded speech signals
IPC: G10L17/00
Filed: 1975-04-08
Abstract: 1508893 Speech detectors NIPPON ELECTRIC CO Ltd 8 April 1975 [8 April 1974] 14378/75 Heading H4R Speech samples in the form of parallel digital code are distinguished from noise by a speech detector having two parallel connected circuits, a first circuit of which is of the amplitude threshold type and the second circuit of which is either of a type which counts the number of zero crossings per unit time of the series of samples, or is of a type which looks at the amplitude difference between successive samples and counts the number of times the amplitude differences oscillate in sign; both arrangements have a threshold count level which when exceeded causes a speech present signal to be given. In Figure 1 PCM coded samples comprising a sign bit b 1 and amplitude bits b2-bn are supplied to an amplitude threshold type speech detector 110 which includes a counter 133 which is incremented each time a sample exceeds a threshold level and is decremented each time the sample is below the threshold, a speech present signal being given via OR gate 150 when a predetermined count is exceeded. The second detector 120 is of one of two types. In Figure 1 a reversible counter 143 is incremented each time a 1 to 0 or 0 to 1 transition occurs in the sign bit bl and is decremented if the sign bit remains unchanged. Alternatively (Figure 3, not shown) an amplitude difference circuit is used to produce an indication as to whether the difference between two successive samples is positive or negative. The counter is then incremented each time a change in the sign of the amplitude difference occurs and is decremented each time the sign remains unchanged. Figure 2 shows a variation of the Figure 1 arrangement wherein the accumulator 133 also serves the function of counter 143. The detector may be applicable to T.A.S.I. or to echo suppressors.

Title: Improvements in coupling devices for railroad vehicles
IPC: B61F3/12
Filed: 1935-05-17
Abstract: 437,173. Railway-vehicle couplings and undercarriages. BUGATTI, E., Molsheim, Bas-Rhin, France. May 17, 1936, Nos. 14491, 14492, and 14493. Convention dates, May 19, 1934, Nov. 22, 1934, and April 10, 1935. [Classes 103 (v) and 103 (vi)] A coupling device for connecting the units of an articulated railway vehicle, locomotive, &c. comprises a coupling-beam or equivalent member which connects the two adjacent axles or trucks of the vehicles and is rigid in the transverse direction, one or two vertical guiding members secured to the beam, and coupling-bars adapted to connect the vehicle underframes with a common universal joint or with two universal joints slidable on the vertical guide or guides, as the case may be. In the arrangement shown in Figs. 2 and 3, the adjacent axle-trucks of the two vehicles are connected by a single rigid beam 20 balljointed at its two ends 21, 22 in sockets 23 on the truck frames, while a single vertical guide 19 is secured to the beam and is slidably engaged by fork members 17, 18 pivoted respectively to the coupling-bars 11, 12 associated with the underframes 9, 10. One of the coupling- bars, e.g. 12, is sprung by means of a spring 30 and is capable of swivelling about an horizontal axis, while the other one is fixed, such arrangement permitting a relative rolling movement between the two vehicles. The sockets 23 are mounted on vertical sleeves 24 slidable laterally in guides on the truck frames against the action of centralizing springs 25. Helical springs 27 are inserted between the underframes and trucks, bearing upon shoes 28 that are adapted to slide or roll upon tables 29 on the trucks. Modifications are described in which the relative vertical movement between the truck and underframe is compensated for otherwise than by sliding movement of the coupling-bars relative to the guide 19. In another construction, Fig. 6, the ends of the coupling-beam 20 are universally jointed at 51 to casings enclosing and sprung with respect to the axles. In place of a single rigid coupling-beam, an articulated beam 66, 67, Fig. 13, may be employed, e.g. in the form of two fork members pivoted to a common transverse member 68 so as to provide rigidity in the transverse direction. In a further modification, Fig. 17, the coupling- beam is formed of two parts 71, 71<1> adapted to be united by a pair of screw or like members 80, and each part carries a vertical guide 82 on which the-coupling bar 89 connected to the underframe is slidable. With such an arrangement, two vehicles can be disconnected, by uncoupling the two parts 71, 711 of the beam. Further constructions are described in which the coupling-beam is hollow and preferably in two parts each accommodating power means for driving the truck axles. In still further constructions the supporting springs, instead of being disposed between the trucks and underframes, are arranged between the coupling-beam and underframes, or between the coupling-beam and truck frames.

Abstract: 726,471. Refrigerating. JOERGENSEN, H. May 26, 1953 [May 27, 1952], No. 14684/53. Class 29. [Also in Group XXIX] A throttle valve included in the suction line 2, 3 of a compression refrigerating system comprises a valve seat 4 and a pressure relieved piston valve member 6 the spindle 22 of which is actuated by two bellows devices 8, 13 respectively subject to the pressure in the evaporator transmitted through ports 7 in the valve member 6 and to the pressure created in a thermal detector bulb 16 located in the refrigerated space. The arrangement is such that for a given temperature in the refrigerated space the bellows 8 will cause the valve to maintain a particular constant evaporator pressure but when the temperature rises or falls the bellows 13 loads the valve so that the maintained evaporator pressure is lower or greater than before, respectively. Bellows 8 includes a casing 9 loaded by a spring 10 acting against a plate 19 which carries columns 18 supporting a casing 14 of the bellows 13. Bellows 13 moves a casing 12 connected by a nut 23 to the top of the valve spindle 22 and loaded by a spring 25. By unscrewing the nut 23 and the connections 26, the temperature responsive device may be removed. An insulating sleeve 20 prevents the cold of the suction line being transferred to the bellows 13. If the valve is located in the refrigerated chamber, the control bulb 16 may be omitted and the temperature in the chamber then acts directly on the bellows 13.
