Title: Circuit arrangements for synchronising a plurality of variable  frequency oscillators
IPC: H04J3/06
Filed: 1972-01-05
Abstract: 1331031 Multiplex pulse signalling SIEMENS AG 5 Jan 1972 403/72 Addition to 1221258 Heading H4L The system for synchronizing oscillators, e.g. clock generators in exchanges disclosed in the parent Specification, wherein the clock frequencies of the local oscillator and of the incoming signals are divided before being compared in a discriminator circuit, is modified to permit the interconnection of clock oscillators of differing basic frequencies. This is achieved by arranging that the timing pulses on the respective inputs are reduced by frequency division to a common repetition frequency, i.e. that produced by the divider operating on the output of the local generator. The dividers may be of the type which produce the required frequency division when averaged over a predetermined time interval.

Apparatus for measuring a turbine blade comprises three pairs of units 10,11,12 each comprising a feeler 13 mounted on a slide 20 on a fixable body 16 and connected by a spring 20E to a sector 28 so that movement of feeler 13 and slide 20 of one unit 10 rotates sector 28 and a block 31 fixed thereon. Movement of block 31 is transmitted to the measuring anvil 60A of a valve 60 (as described in Specification 823, 712) and movement of feeler 13 on the other unit 10 of the pair also moves a block 31, this movement being transmitted via a plunger 54 to the body of the valve 60. Thus a reading is given on a manometer 73 of the relative positions of feelers 13 on units 10. Valves 42, 80 similar to valve 60 are arranged to give the position of a feeler 13 of unit 11 and the relative positions of feelers of units 10,12. Valves are also arranged to give the relative positions of the two feelers of units 11 and similarly of units 12. The pairs of units 10, 11, 12 are mounted on blocks 7, 8 and three sets of blocks 7, 8 may be slidably arranged on a block 1. To measure turbine blades of different sizes the positions of the blocks 7, 8, the body 16, the block 31 and feelers 13 may be individual adjusted prior to the gauging operation. A setting up device (Fig. 5 not shown) is provided for this purpose. In another embodiment (Fig. 6) the means for transmitting movement from block 31 to valve 60 is altered and so is the way of separating feelers to insert blade 9.

Abstract: 718,874. Refrigerating. ELECTROLUX, Ltd. Jan. 8, 1953 [Jan. 23, 1952], No. 586/53. Class 29 In continuous-cycle inert-gas absorption apparatus having high and low temperature evaporators 24, 23 insulated from each other, a pipe 10 conveying weak gas having a constant partial pressure of refrigerant vapour is arranged in heat exchange with gas flowing in contact with liquid refrigerant both in the high and low temperature evaporators, and having a partial pressure of refrigerant increasing in the direction of flow due to the evaporation of refrigerant into it. The upper evaporator 23 is intended for deep freezing and may operate at -20‹ to -25 ‹C, while the lower cabinet cooling evaporator 24 operates at a higher temperature and has fins 25. Weak gas from the absorber passes through the pipe 10 which forms the inner conduit of the gas heatexchanger and then passes through the outer jacket of the lower evaporator 24 in which gas enriched with refrigerant flows from a pipe 26 to the absorber. Part of the weak gas enters the outer jacket of the evaporator 24 through an opening 27 in the pipe 10 and the remainder passes on by a pipe 28 to the upper evaporator 23 issuing into the outer jacket of this evaporator through an opening 29. The enriched gas passes through conduits 26, 24, 30 and the outer jacket of the gas heat exchanger back to the absorber. Condensate is supplied to outer jacket 11 of the gas heat-exchanger by a pipe 32 and flows through the jacket and through a conduit 33 into the low temperature evaporator 23 and flows therethrough in counterflow to the rich gas. Excess refrigerant passes through a conduit 34 into the 'evaporator 24 from which any further excess drains by a conduit 35. The straight pipes shown may be replaced by flat pipe coils 37, 38 in a plate-like cooling body 39, 40 shown developed in Fig. 2 and the heat exchange may be by direct heatconductive contact between the weak and rich gas pipes or by conduction through the cooling body. The weak gas pipe 36 may be consideraly shorter than the rich gas pipe. The weak gas can be introduced into the rich gas pipes 37, 38 through a plurality of conduits 43 ... 48 arranged at spaced points along the rich gas pipes and in heatconductive connection therewith. The lowtemperature coil 37 and the high-temperature coil 38 are spot-welded or clamped to flat plates 39, 40 connected by a plate 41 which forms the side wall of the plate-like cooling body when the plates 39, 40 are bent towards one another and welded together with or without the interposition of solid insulation. The plate 40 may be provided with fins or replaced by a fin pack on the high-temperature coil 38. Refrigerant is supplied at 16 and a throttle for the gas may be provided at 42 or the conduit 36 may be closed at this point, the weak gas entering only through the conduits 43 ... 48, The refrigerant conduit 16 may also be in heat-conductive connection with the plates 39, 40.

Abstract: PURPOSE:To quicken the signal discrimination including discrimination of absence of received broadcast by providing a BS discrimination means discriminating the system of the received broadcast signal based on the result of detection with a BS reception broadcast presence detection section and a carrier presence detection section. CONSTITUTION:When a channel selection signal is outputted to a BS tuner section 2 by a channel selection means 3, the BS tuner section 2 is operated to receive a signal of a prescribed frequency (channel) signal and when a reception signal is in existence, a reception signal is outputted to a MUSE decoder 4, an NTSC decoder 5 and a PCM decoder 6 or the like. Then an AGC output of the BS tuner section 2 is led to a BS reception broadcast presence detection section 7 and an audio signal inputted to a PCM decoder 6 is led respectively to a carrier presence detection section 8 and a BS discrimination means 10 outputs a discrimination signal based on the output state of carrier detection sections 7, 8. In this case, the presence of received broadcast and the presence of a carrier of the audio signal are detected at a high speed (nearly 10msec). Thus, the signal is discriminated at a high speed.
