Title: Improvements in or relating to electro-mechanical filter devices
IPC: H03H9/50
Filed: 1960-09-15
Abstract: 959,394. Electromechanical filters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 15, 1960 [Sept. 18, 1959], No. 31809/60. Heading H3U. An electromechanical filter comprises a series of dumb-bell shaped resonators 1, 2, 3, 4, joined by coupling rods k having a stiffness small compared to the stiffness of the connecting members c of the resonators. This requires that the quotient of the fourth power of the circumference and the axial length of the connecting members should be a few times greater than the corresponding quotient of the coupling rods. The total length of each dumbbell shaped resonator is only a small fraction of a wavelength at the central frequency of the filter. The whole system is machined from a single piece of Ni-Fe alloy and is driven in a torsional mode by magnetostrictive elements 9 which are dimensioned to be resonant at the central frequency of the bass band. These are excited by tuned coils 15. The output transducers 11 are similar. The filter may, alternatively, be operated in a longitudinal mode. In order to match the filter to the transducers, the lengths of the coupling rods k and of the connecting members c are varied in such a manner that the stiffness of the former gradually increases from the centre of the filter towards the transducers and the stiffness of the latter gradually decreases. Further, additional discs (not shown) may be provided on the coupling rods 13, 14 between the transducers and the supports of the filters. These additional discs and the coupling rods joining them may increase in mass from the supporting points towards the transducers.

Filed: 1974-07-19
Abstract: 1472949 Photo-electric analysis ITT INDUSTRIES INC 19 July 1974 [20 July 1973] 32071/74 Heading G1A Electro-optical apparatus includes a photometric analyzer having a probe mountable so that an inner end can extend inwardly from a wall into a region containing at least one material, the analyzer providing an output signal S o  = e o e t , where e o  is proportional to a parameter of the material and e t  is a function of the material temperature; variable gain means responsive to the signal S o  ; a first temperature sensor mounted adjacent the material and so connected that the output of the variable gain means is proportional to S o  ¸ e t ; and a second temperature sensor operable to switch the gain means from variable to constant gain at a predetermined temperature. A flue gas analyzer 10 Fig. 1, e.g. for SO 2  or NO 2 , has a probe 19 extendable through a chimney wall, carrying at its inner end a housing 20 enclosing at least a pair of nickel resistors 21, 22. The output of a function generator 13 (e.g. a diode circuit) following the analyzer 10 is a signal S o  = e o e t , the dimensionless variable e t  being given by e t  = -At + B, where t Kelvin = thermodynamic temperature, A and B are positive coefficients, stated to be substantially constant over a temperature range 345-600K. A temperature compensating circuit 14 Fig. 1 connected to the resistors 21, 22 provides a corrected output voltage to an analogue meter 15. If more than one gas is to be measured, other channels, e.g. 16, 17, 18, may be provided and connected to further pairs of resistors, e.g. 23, 24, in the housing 20. The temperature compensating circuit 14 Fig. 3 comprises an amplifier 31 having in its negativefeedback loop one of the nickel resistors 21, whereby the voltage gain of the circuit is rendered substantially proportional to the sum of the resistance 21 and of the fixed resistances 74, 75 and the variable resistance 73 in series. A datum output is settable by the potentiometer 55 feeding an adjustable voltage to the non-inverting input 33 of the amplifier 31. Circuit values are chosen so as to give the actual temperature compensation curve a good approximation to the ideal reciprocal of e t  over the required temperature range. For temperature ranges (e.g. below 345 K) where the photometer output may be substantially unaffected by temperature, a switch 66 may be operated by a relay coil 65 to change over the amplifier 31 feedback loop to a constant resistance chain 78, 80, 81. The relay coil 65 is supplied by a transistor 97 controlled by an amplifier 91 responsive to a resistance bridge 103 having one arm connected to the second nickel resistor 22. Snap action of the changeover is provided by a positive feedback resistor 95.

Title: Improvements in or relating to induction motors
IPC: H02K17/16
Filed: 1927-11-29
Abstract: 281,344. Schwarz, B. Nov. 29, 1926, [Convention date]. Alternating-current motors.- The secondary winding of an induction motor is in two parts, located in separate sets of slots so as to have different inductances, the windings of one part being so connected to those of the other that the individual coils of phases of one part are short-circuited by corresponding coils or phases of the other part, there being no relative phase displacement of the currents in the mutually shortcircuiting coils or phases. Fig. 1 shows a winding comprising a single-turn coil W1 in the outer slots N1, N2 connected in series with a similar coil W2 in the inner slots N<I>1,N<1>2. The inner coils have greater magnetic leakage than the outer coils and at starting acts as choking coils. An additional highresistance starting winding Wa may be provided. Fig. 2 shows one phase of a three-phase four pole winding, the inner and outer coils W<1>, W being shown separately. The starting characteristics of the motor may be improved by connecting a resistance R to the coil terminals A, E or A<1>, E<1>. Instead of the phase winding shown, two continuous current type windings S, S', Fig. 3 may be employed situated respectively in the outer and inner sets of slots and interconnected to form shortcircuited coil groups. The number of interconnections X may be equal to or less than the number of coils and resistances R may be connected permanently between the interconnections. According to the Specification as open to inspection under Sect. 91 (3) (a) a closed coil has the conductors of one side in outer slots and the conductors of the other side in inner slots. The continuous-current type of winding shown in Fig. 3 may be connected to a commutator in which case the coil groups, which are connected together must be displaced angularly with respect to each other by an amount depending upon the purpose in view. For example in the case of a compensated shunt motor, Fig. 6 (Cancelled), in which the commutator brushes are fed from an auxiliary stator winding H the relative angular displacement of the commutator windings S, S<1> is chosen to give the desired power factor and/or speed regulation. Permanent resistances may be combined with the rotor windings or a starter r<1> may be included in the circuit between the commutator and the winding H. This subject-matter does not appear in the Specification as accepted, but forms the subject of divided applications.
