Title: Improvements in or relating to blade cascades for turbo-machines
IPC: F01D5/14
Filed: 1963-12-02
Abstract: 1,067,169. Turbine and compressor blades. ESCHER WYSS A.G. Dec.2, 1963 [Nov.30, 1962], No.47407/63. Heading F1T. An axial flow turbine or compressor sheet metal guide blade a has the tangent to the mean camber line s of the blade profile inclined at an angle # 1  to the blade assembly front g at the inlet edge and at a lesser acute angle # 2  at the outlet edge. At a position S, at a distance b from the assembly front g larger than one-quarter but less than onethird of the total axial width c of the assembly, the mean camber line s passes through a point of inflection at which the tangent to the line makes an angle # s  greater than # 1  with the assembly front g. The angles # 1  and # 2  are not greater than 90‹ and 30‹ respectively. The entry angle # 1  may be varied along the blade edge without twisting the blade by cutting back parts of the leading edge up to and beyond the point of inflection. In a modification, Fig.2 (not shown), each blade is thickened in the vicinity of the narrowest part of the flow passage between the blades. The construction reduces frictional flow losses and improves the strength of the blade assembly which may be used to support a partition in a steam turbine.

Abstract: 1381898 Locks BOMORO BOCKLENBERG & MOTTE GmbH & CO and DAIMLER-BENZ AG 20 Oct 1972 [22 Oct 1971] 48448/72 Heading E2A In a lock for a door and having a rotatable bolting element 4 which engages in the event of closure of the door, in a keeper, and the securing position of which secures a catch 7 releasable from the bolting element by a releasing lever 13 associated with a securing lever 20 for the purpose of blocking the releasing movement or for disengaging its connection with the catch, a constrained-bolting lever 31 is indirectly connected to the lever 20 and has a part 43 which moves the catch, e.g. via a stop 44, when the lever 31 is actuated. As shown, the latch 4 is retained in the securing position by the catch 7 which has a cam 9 engageable in a notch 10 in the latch and the lever 20 engages a pivoted lever 17 to which is pivoted a lever 16 carrying a pin 15 movable in a guide slot 19 of the lever 13 and so that the free end of the catch can be moved to allow the catch to be disengaged from the latch; the lever 20 is actuated by a peg 27 carried by a member 26 rotatable upon operation of a cylinder lock 26, or by a knob or a linkage acting on the arms 23, 24 thereof. The lever 31 pivoted at 30 on the lever 17 is displaceable by pivoting of the lever 17 and includes a control edge 35 associated with a peg 33 on the latch 4, and a gate 36 guided by a peg 37 and formed with cut-outs 38, 39. When the latch is brought to a door-securing position, the peg 33 moves from the position shown in Fig. 6 to that shown in Fig. 1 and the lever 31 follows the peg under the action of the spring 42, the movement of the lever being arrested by the peg 37 whereupon the peg 33 is lifted off the edge 35 and movement of the lever 20 is possible since the peg 37 is then able to enter the cut-out 39 when the levers 17, 31 are raised; the lever 31 has a nose 43 which is moved up to a stop 44 on the catch 7. The lever 21 is prevented from operation in intermediate positions thereof since the peg 37 bears against that part of the gate which is eccentric with the axis 30. To ensure that the lock can be secured, even when the door is open, by actuation of the lever 20, the peg 37 seats in the cut-out 38 of the gate if the lever is actuated with the latch in the unsecured position, Fig. 6; in this case engagement of the catch 7 with the latch 4 does not occur. Inadvertent looking of the door by actuating the lever 20 before closing the door is prevented by dispensing with the cut-out 38. The centre of gravity of the levers may be located at the axis of rotation thereof and, if necessary, with the assistance of weights.

Abstract: 1,177,211. Welding by pressure. CATERPILLAR TRACTOR CO. 7 Feb., 1967 [16 Nov., 1965], No. 48585/65. Heading R3B. In bonding a first steel workpiece to a second steel workpiece, an amount of energy needed for bonding the workpieces is stored in a rotating inertia mass coupled with the first workpiece, a pressure is applied to force the surfaces of the workpieces into rotational rubbing contact with the initial speed of the circumference of the surface of the first workpiece relative the second workpiece in excess of 275 feet per minute and the rotational rubbing contact is continued until the surfaces bond and the stored energy is expanded as the inertia mass comes to rest. The initial speed is preferably greater than 350 feet per minute and less than 1500 feet per minute. The process may be carried out using the apparatus described in Specification 1,025,762. The process comprises a first stage I in which the workpieces are engaged and power is at a maximum, e.g. 195 HP per square inch of interface, a second stage II from the moment of maximum power to a marked increase in torque and a marked decrease in power and a third stage III in which the workpieces rotate relatively to one another at least one quarter of a revolution, e.g. 1 ¢ revolutions to provide plastic working and in which the inertia mass comes to rest. The third stage may begin at a relative speed of 220 feet per minute.

Abstract: 1528138 Stereo recording NIPPON COLUMBIA KK 28 Nov 1975 [29 Nov 1974] 49051/75 Heading H4R In a CD4 type of recording and reproducing apparatus in which the recorded signal includes, on each groove wall, a main signal and an angle modulated sub-carrier signal, the angle modulated sub-carrier signals are passed through filters providing a 6 dB/octave response to provide a constant acceleration recording characteristic for the sub channel signals. A complementary filter is provided before the demodulator in the reproducing apparatus, the filter may be separate or combined with the sub-carrier separating filter. The arrangement allows an increase in sub-carrier signal level in the region below 30 kHz, where harmonic distortion of the main channel signal can cause interference and drop outs in the subchannel signal, while not increasing the carrier level above a value which would cause curvature overload of the reproducing stylus. Preferred embodiment Figs. 5 and 6.-Four channel signals of a quadraphonic source are coded at 2 according to the Universal Matrix system to provide signals T L  T R  T T  and T Q  where The resulting signals are filtered and phase compensated at 3, the signals T L  and T R  are passed through an R1AA recording equalizer 4 to a combining circuit 5 while the TT and T Q  are fed through pre-emphasis circuits 10, 11 to angle modulators 6 and 7. The angle modulated signals T T <SP>1</SP> and T Q <SP>1</SP> are passed through filters, having 6 dB/octave falling characteristic, to the combining circuit 5 for addition to the signals T L  and T R  and recording on the record groove walls. The reproducing apparatus is conventional apart from the addition to a filter 31 having a 6 dB/octave rising characteristic in the feed of the signals T T <SP>1</SP> and T Q <SP>1</SP> to the demodulator, or alternatively in modifying the normal separating band pass filter 19 to have a 6 dB/octave rising characteristic over the pass band. The filters 6a, 7a and 31 may be formed by operational amplifiers having respectively parallel RC and series RC circuits in their feedback paths, Figs. 9 and 10 (not shown).

A magnetic core decoder of the type in which to select a single output winding, current is passed through a combination of input conductors, so threading a plurality of cores so that their inductive effects cancel except in the selected output winding, is characterized in that (a) each input-conductor is connected in series with a unidirectional conductive element, (b) both the input ends and the output ends of the input-conductors are connected in a number of groups to a number of switches and in that (c) to cause current to pass through a selected combination of input-conductors selected switches at both their input and output ends are energized. As shown in Fig. 1 sixteen input-conductors 10-25 are connected at their top (input) ends to switches 52, 53, 54, 55 in groups of four, and, at their bottom (output) ends, via diodes, to switches 56, 57, 58, 59 in four different groups of four. To select a particular one of the nine output windings 35-43 two switches from each group of four are energized. The arrangement is such that it is possible to produce output pulses of either polarity in any of the output windings. In a modification, Fig. 3, the input-conductors are connected to two groups of four switches as in Fig. 1, but each output winding threads several cores. The result is that selection of two switches in each group effectively selects two cores in the same row but their output pulses cancel except in a single output winding.
