In a loading unit for a machine tool in which a rotary tool magazine store and a rotary work pallet store are each indexed to present a tool magazine 7 and a work pallet 13 at adjacent vertical stations to be fed into a machine tool, the respective stores are indexed by an hydraulic jack 30, 41 that pivots a movable element 16, 39 about a shaft 1, 8. The movable element 16, 39 has a pneumatic jack operated finger that engages and disengages from a slot 27, 40 in the paddles 2-6 and 9-12 that make up the respective stores. The finger engages in the slot as the piston-rod of the jack 30, 41 retracts and causes rotation of the store. A further fixed element 36, 44, similar in operation to the movable element 16, 39, has a finger for engagement in a slot in a paddle to hold the store against rotation as the finger in movable element 16, 39 is retracted and the jack 30, 41 rotates the movable element 16, 39 back to its start position.

Abstract: 1,253,031. Companders. R. M. DOLBY. 1 Jan., 1969 [10 Jan., 1968], No. 1540/68. Heading H4R. In a modification of the compander system of Specification 1,120,541 in the compressor the signal in the further path 10 is derived from the output of the adding network 12 and in the expander the signal in the further path 14 is derived from the input to the subtractor 16. The further path, as in the prior application, may include a number of parallel limiting circuits operating at different levels and/or on different frequency bands and may include tuned circuits to reject the carrier frequency in carrier systems, e.g. colour television systems. Fig. 6 shows a simple expander, which is of application to a television video signal and is an inverted form of the expander of Fig. 2 providing limiting and low frequency discrimination in the further path the signal from which is combined with that from the direct path via R1. For colour television a parallel resonant subcarrier rejector can replace or be connected in series with the capacitor. A down turning characteristic may be obtained by combining in opposition the signals from two further paths having the same limiting level but different slopes up to the limiting level.

Abstract: 1,258,356. Stacking bricks; handling thin material. SIGNODE CORP. 20 Feb., 1970 [27 Feb., 1969], No. 8237/70. Headings B8C and B8R. Courses of bricks are stacked with the interposition of a supporting sheet of veneer between a course with fork lift openings and the upper adjacent course, and of separating sheets of paper between the remaining pairs of adjacent courses. As illustrated, bricks from a conveyer 30 are transferred, one course at a time, by a carrying assembly 32 to an elevator at a stacking station 28. The elevator is lowered by one increment when photo-cells sense the presence of a new course of bricks. After the elevator has been lowered, a sheet is fed to the top of the stack from a vertically movable hopper assembly 40 comprising an upper hopper 44 which contains supporting sheets V, and a lower hopper 42 which contains separating sheets P. The assembly 40 is normally positioned to feed a separating sheet to the stack but may be moved under manual control to feed a supporting sheet. A supporting sheet is fed from the bottom of the hopper 44 by the engagement of abutments 256 on an endless chain with the bottom sheet in the hopper. The sheet is captured by rollers 64 and 66 and transferred by them to the top of the brick stack. During transfer, the sheet is supported by jets of air from compressed air pipes 222 and 224. When a separating sheet is to be fed to the stack, the assembly 40 is raised so that a sheet P 1  fed from the top of the hopper 42 via a discharge opening 80 is similarly transferred by the rollers 64 and 66. The sheet P 1  is contacted by rollers 106 on a feeding assembly 82. The rollers include one way clutches so that when the assembly 82 is moved to the right, the rollers are locked and move the sheet P 1  by frictional engagement. When the assembly 82 moves to the left, the rollers are free to rotate so that the sheet P 1  is undisturbed. After the feeding assembly 82 has been moved fully to the left, a spring (168), Fig. 7 (not shown), moves the assembly slightly to the right so that a bulge is created in the sheet P 1 . When the sheet P 1  is to be discharged, a suction cup 198 is lowered to engage the bulge and then raised to lift the sheet over a projection 92 on a stop 86. The sheet is then discharged by movement of the feeding assembly 82 to the right. The level of separating sheets in the hopper 42 is sensed by a feeler 240 in response to which a base plate 78 is raised to keep the top sheet in line with the discharge opening 80. The transfer of sheets from the hopper assembly to the stack is monitored by photo-cells which are able to distinguish between the supporting and separating sheets.

Each cam moves in a slot 20 in the coaming 10, the slot being shaped, Fig. 6 (not shown), so that when the cam is in its ghost position, a roller will move over the slot, but when the cam is moved to its solid line position, a roller can enter the slot. The cams along each side of the hatchway are linked by cable 27 to each other and to two operating pulleys (32 and 33), Fig. 7 (not shown). The pulleys are rotated to move the cams by a drive wheel 37 acting through gearing in a unit 36 which is pivoted about the pulley axis. The hatch cover is driven along the hatchway by the engagement of a driven pinion 15 with pins 16 projecting from a rail 13 on which runs a roller (14) coaxial with the drive wheel. Removal of a pin 36a allows a rail section 41 and its associated pins 16 to fall into a slide box 40 so that the pinion 15 and its associated roller (14) are free to move downwards on operation of the cams. Removal of the pin 36a allows the unit 36 to be pivoted to a position, Fig. 2 (not shown), in which pins 38 on the drive wheel 37 are engaged by the pinion 15. The unit 36 is held in position by inserting the pin 36a into a hole in a lug 39 and an aligned hole m a fixed bracket. Operation of the normal hatch cover drive then acts through the drive wheel 37 to move the cams 24. In another embodiment, Figs. 8-12 (not shown), the cam cables have their own drives in the form of rams which act to displace pulleys around which the cable runs. The hatch cover is itself moved by cables operated by a derrick or winch. In a further embodiment (not shown), the cables along the sides of the hatchway are linked by a cable extending along one end of the hatchway and the two ends of the resulting drain are acted on by a jack or jacks to give the required wedge movement.

Abstract: 1316479 Processing seismic records MOBIL OIL CORP 23 Nov 1970 55550/70 Heading H4D Distortion, e.g. due to multiples, is removed from recorded seismic data by a frequencydomain filtering technique in which the filter functions are derived from the envelopes of the real and imaginary complex components of the seismic data in the frequency domain. In the Fig. 6 system an input seismic data trace S is Fourier-transformed at 31 into its frequency spectrum. The envelope of this spectrum is characteristic of the distortion and is used for deriving inverse filter functions for removing the distortion. To this end, the spectrum is separated into its real and imaginary components, the envelopes of these components are derived at 32, 33 (e.g. by convolution with operator functions), the modulus of the spectrum envelope is provided by squaring at 50, 51, adding at 52 and square-rooting at 53, the argument of the spectrum envelope is provided at 54, and the inverse filter functions are then derived at 40 from the modulus and argument. These filter functions are applied at 41 to the real and imaginary components, the resulting filtered data is band-limited at 42 to eliminate noise, and the band-limited signal is Fourier-transformed back to the time domain at 38 to provide a processed trace with the distortion removed. The above processing is applicable to seismograms obtained in marine or land surveying, and may be done by a digital computer (the input seismograms being recorded on magnetic tape). In a modification (Fig. 20, not shown) the modulus and argument of the Fourier spectrum signal produced at 31 are derived, the envelopes of the modulus and argument are obtained, the modulus is filtered with a function derived from the inverse of the modulus envelope, the argument is filtered by subtracting from it the argument envelope, the resulting filtered data is band-limited, and the band-limited data is then Fourier-transformed to the time-domain to provide the processed trace.
