Abstract: 1,238,434. Turbomachine rotors. GENERAL MOTORS CORP. Feb. 5, 1970 [May 13,1969], No. 5584/70. Heading F1T. A turbine or compressor rotor comprises outer and inner concentric rings 9, 10 having blades mounted on at least one of the rings and extending radially outwardly of the outer ring 9 and tension spokes 34 extending between the rings, the spokes having an inward component of direction from the point of attachment at each ring so as to put both rings in compression and thus oppose centrifugal forces on the rings. As shown, the rings 9, 10 respectively support in dovetail slots the roots 19, 13 of blades 18, 11, the latter blades extending outwardly through apertures in the ring 9. This ring comprises forward and rearward portions 22, 23 connected by a circumferential tenon joint 25 so that the ring can be assembled around the blades 11. The ring portions 22, 23 are integral with respective discs 26, 29 and hubs 27, 30, the discs providing a barrier against flow of working fluid axially between the rings 9, 10. One of the discs may be omitted. Each spoke 34 has a ball end (43), Fig. 4 (not shown), seated against the outer surface of the inner ring 10 and a threaded end (45) receiving a nut (46) which bears against the outer surface of the outer ring 9 to permit adjustment of the spoke tension. In a modification, Fig. 3 (not shown), the inner ring (60) has an integral disc (61) and hub (62) at its forward end, the forward disc (66) of the outer ring (59) being sealed to the hub (62) by a piston ring seal (67).

Abstract: 1,251,467. Processing spent nuclear fuel. KERNFORSCHUNG m.b.H. GES FUER. 26 Aug., 1970 [28 Aug., 1969], No. 40948/70. Heading G6R. In a nuclear fuel processing plant, the quantities of the constituent isotopic components at the plant input and output are measured in order to determine the amount of fissile material present in the plant during operation. As different isotopic components are fed into the plant during the time of operation, the measured plant output is used to calculate the plant contents. The system operates without plant shutdown and the measurements at the input and output are effected during a time period corresponding to the transit time of the material through the plant. The equations connecting the input and output quantities with the plant contents are linear and are solved by a determinant coefficient-matrix method, there being as many equations as there are unknown component quantities.

Abstract: 1,257,133. Upper thread tensioner. MEFINA S.A. 25 Nov., 1969 [6 Dec., 1968], No. 57510/69. Heading D1G. An adjustable tensioning device in a sewing machine comprises a spindle 6 carrying at least two tension discs 5 gripping the upper thread, a spring 8 acting indirectly on the spindle to urge the discs together, a knurled adjusting knob 9 controlling a cam 11 which engages a first lever 14, and a second lever 23 engaging both the spring and the spindle. As shown, both levers are pivoted side by side on the common spindle 15. The lever 14 is connected to spring 8 at one end thereof by an adjustable nut and bolt 20, the end of lever 23 remote from its pivot has a fork engaging a slot in spindle 6. A side projection 27 on lever 23 engages below spring 8. The cam 11 has notches 12 which cooperate with the free end 13 of lever 14 to define a number of tension adjusting positions, the knob 9 having an appropriate scale. A pin (29, Fig. 3 not shown) engages slots (28) in the discs 5 to prevent their rotation. The presser foot lifting lever 56 carries a pivoted rod 58 which engages lever 23 at 61 to release the thread  tension when the presser foot is raised. In modifications the levers 14, 23 may be disposed in super position, may have separate pivots and the knob and cam may be disposed horizontally. When two upper threads are employed in the machine the threads are guided to pass round the tensioner in opposite directions.

Abstract: 1,266,411. Feeding tobacco. SERVICE D' EXPLOITATION INDUSTRIELLE DES TABAUS ET DES ALLUMETTES. 17 Feb., 1969 [15 Feb., 1968], No. 8407/69. Heading A2C. [Also in Division B8] In a device for receiving a non-homogeneous stream of material such as tobacco in shredded or flake form and delivering a continuous, uniform outflow, the stream is accelerated along a passageway of decreasing cross-sectional area defined by a plurality of pairs of rotary impellers 102, 102'; 103, 103' &c. running at increasing speeds in the direction of flow and of outside diameters which decrease in proportion to the decrease in the flow area. As shown, three pairs of vaned impellers 102, 102'; 103, 103' and 104, 104' are spaced so as to leave a free flow area between the impellers of each pair whilst the impellers 105, 105' of a fourth pair are spaced such that the cylinders generated by their rotation are tangent to each other. The vertical spacing between impellers may be reduced, and in one embodiment, with seven pairs of impellers and a casing with straight, tapering sides, the vertical spacing between two pairs of impellers is reduced to such an extent that the generated cylinders intersect, the edges of the vanes having mating serrations to allow rotation at differing speeds. In a further embodiment the impellers in the upper stages have studs instead of vanes, and the casing may be dispensed with.

Abstract: 1,266,550. Pick-up arm movement. OLYMPIA WERKE A.G. 12 July, 1969 [15 June, 1968; 26 April, 1969], No. 29865/69. Heading G5R. In a device for lifting and transversely moving a gramophone pick-up in e.g. a dictating machine, transverse movement is prevented until the pick-up is lifted from the record. Inward and downward movement on push button 20 moves a pawl 6 into engagement with rack 7 to prevent transverse movement of setting lever 3; at the same time projection 5 on the setting lever engages tilt rod 9 secured to pick-up 1 to lift the pick-up from record 4 by tilting the arm carrying the pick-up 1 and counterweight 26 about pivot 8. Further inward movement of the push button releases cam 6 from the rack to allow transverse movement of the pick-up with respect to the record track. The inward movement of the setting lever is allowed by a slotted connection 23 between the lever and tone arm 2 which is mounted 18 for pivoting in a horizontal plane. The setting lever 3 and a stop member 15 on the tone arm-are shaped such that sideways movement applied to the control button 20 produces a downward pressure on. the lever thereby moving the cam 6 into engagement with the rack to stop the movement being applied to the pick-up.  A number of other embodiments of the invention are described.

As shown, the R-impulse detector 1 includes an amplifier 2, filter 3 and threshold detector 4, whose output is applied to synchronize the generator 6, reset counter 8 and provide one input for the AFC 9. The generator 6 provides pulses having a repetition frequency 100 times that of the heart cycle, and by utilising a switch and matrix decoder in the counter, selected pulses are provided at outputs 11. The AFC 9 detects changes in heart cycle frequency by receiving one input from the impulse detector 1, and another input from the counter when 50 pulses have been counted, to automatically vary the frequency of generator 6. The AFC includes a flip-flop 12, a time lag element 13 including an RC network and an amplifier, and a pulse element 14 including a gate, a capacitor, and an emitter follower. A change on unequal states of flip-flop 12 causes a frequency change. The threshold circuit 4 includes a Schmitt trigger and two univibrators, the first of which has a pulse duration sufficiently long to prevent double operation of the seond by the same R- impulse.
