Abstract: 1343656 Echo suppressors WESTERN ELECTRIC CO Inc 16 Nov 1971 [16 Nov 1970] 53032/71 Heading H4R  In an echo suppressor the transmit signal path includes a number of filters 19-23 of contiguous pass band each of which is followed by a respective centre clipper 24-28 the output from which are filtered, to remove distortion products by filters 29 to 33 before the signals are combined for transmission. The centre clipping level is varied according to the level of echo signal expected in the path, e.g. by deriving control signals from the signal in the receive path via a similar set of filters, 19a to 23a, to those, 19 to 23, in the transmit path. Attenuators 34 to 38 are set to provide a loss so that the control signal levels match the echo, e.g. produced in the hybrid. The setting of the attenuators can be adaptively adjusted either before or during transmission by injection of tones or white noise into the receive path and automatic adjustment of the attenuators to just remove the tones or noise from the processor unit 17 output, Figs. 5 and 6 (not shown). The arrangement can be used in a loudspeaking telephone set and in such a case a pair of processor units (17, 17a) can be provided to cancel both hybrid unbalance and loudspeaker to microphone cross talk, with the transmit path filters (19 to 23) being also used to derive the control signals for the centre clippers following the filters (19-23) in the receive path, and vice versa, Fig. 9 (not shown).

Title: Brick stacking apparatus
IPC: B65G57/26
Filed: 1974-12-19
Abstract: 1487370 Brick stacking; rotatable frame AMI INDUSTRIES Inc 19 Dec 1974 [9 Jan 1974] 55023/74 Headings B8C and B8H Brick stacking apparatus includes a transfer table 26 supplied with spaced rows 44 of laterally abutting bricks, a pusher 24 to move the rows off the table 26 and on to a marshalling support 27 causing the support to move with the bricks, means, for example a chain drive, for moving the support further to space the rows from the table 26, and stacking means 28 to transfer the bricks from the support to a stacking platform 29. A gripper assembly (18) rotatable through 90 de grees about a vertical axis and carried by an overhead trolley movable in two perpendicular horizontal directions simultaneously unloads a grid from each of four stacks on a kiln car and deposits the grids on bars 34 of a spreader table 37 to form the rows 36. There are four groups of bars 34 the outer bars of each group having side plates 35. The outer bars are movable inwardly to eliminate any misalignment in the rows 36 and then outwardly to space the rows. The grids and thus the rows 36 comprise upper and lower bricks. The pusher 24, reciprocated by a chain 40 and tiltable for return travel by an actuator 50, pushes the spaced rows through guides 37 on the table 26 and on to the support 27. The support is moved from a position under the table when the rows engage a gate 41 at the front of the support. There are also further gates (41, 42) arranged transversely of the table which are raised when a stack layer 32a with voids is to be formed. The support is then moved forward alternately by the bricks engaging a mixed gate and by its own drive. The stacking means 28 comprise arms 52, 53 secured to a shaft 49 for rotation therewith from a position over the table 27 to the platform 29. A gripper frame 57 is pivotally mounted on the arms and is connected by a chain 62 and links (66) 67 to a fixed sprocket (58) so that the orientation of the frame stays horizontal as the arms rotate. However rotation of the links (66), 67 by a motor when desired inverts the frame and the layer of bricks carried thereby. The frame includes inflatable elements either to lift first the upper bricks in the rows 47 on the table 27 and then the lower bricks or to lift all the bricks simultaneously. Since only a single void layer 32a is formed in the stacks and a double void layer can be formed on the table 27 a storage frame removes the upper void layer from the table 27 for the next stacks to be formed.

Abstract: 1403918 Filament winding apparatus and method OWENS-CORNING FIBERGLAS CORP 7 Dec 1972 [8 Dec 1971] 56538/72 Heading DIJ A filament winder having guides 88, Fig. 4, that traverse the filaments onto a winding spindle to form packages 72, 74 is characterized by means 40, Fig. 2, for supplying the filaments to the winder at constant speed, means for reducing the angular velocity of the winder so that the rate of collection is constant with changing package size, means sensing the angular velocity of the winder as an indication of package size, and means responsive to said sensing means to move the guides 88 away from the yarn winding spindle during build up of the package so as to provide a predetermined space relationship between the guides 88 and the packages 72, 74. Motor Drive. A motor 104, Fig. 2, drives an eddy-current clutch 106. As the flux is reduced the energy transmitted to the clutch diminishes and this causes the package takeup speed to reduce. Fig. 5 shows a circuit for controlling the flux in the clutch 106. A controller 140, having a patterned rate of change, supplies a control signal to the clutch 106. The controller 140 receives a voltage signal from a transducer 142 that responds to yarn tension, and this signal changes the output of the controller 140 to bring the speed of collection of the strand into conformity with the actual rate of strand feed. For improved stability the controller 140 receives feedback signals from a tachometer 146 measuring the speed of the winding spindle. Traverse Assembly. The traverse mechanism 90 is mounted on a carriage 130 that can move horizontally on support rods 192 and 194. Fig. 6 shows a circuit for displacing the carriage 130 to keep a predetermined spaced relationship between the packages 72 and 74 and the traverse mechanism 90. A battery 200 is connected across a potentiometer 202. The positive output voltage of the potentiometer 202 travels to a summing junction J3. A rectifier 208 rectifies the output of the tachometer 146 and provides a negative voltage to the junction J3. When the voltages supplied to the junction J3 are unbalanced the junction J3, through a switch 198, energizes a grounded solenoid coil 216 to close a switch 218. Closure of switch 218 causes a motor 220 to be energized from a source L3, L4. The motor 220 drives the slider of potentiometer 202 and actuates a drive system that moves the carriage 130 until the voltage from the potentiometer again equals the rectified voltage from the tachometer 146 at which point the solenoid coil 216 is not energized, the switch 218 opens and the motor 220 stops. Ribbon winding preventing. As shown in Fig. 4 the filament guides 88 are traversed by cam followers 100 sliding in the grooves 98 of barrel cams 96. The barrel cams 96 are rotatably mounted in a tubular housing 90 and to prevent ribbon winding additional means are provided to reciprocate the housing 90. Fig. 2 illustrates a wheel cam 286 that is driven by the means rotating the barrel cams 96, the wheel cam 286 serving to reciprocate the housing 90.
