Title: Devices for reducing turbulence
IPC: E04H4/14
Filed: 1969-10-08
Abstract: 1282479 Turbulence-reducing lane marker for swimming pools SWIMQUIP Inc 8 Oct 1969 [4 Feb 1969] 49429/69 Heading A4N A turbulence-reducing device for swimming pools has a cylindrical housing 23 containing a buoyant member 31, a plurality of substantially imperforate ribs 24-27 extending from the housing 23 and supporting a body in the form of spaced apart rings 28, 28a. The body of the device is made in two parts (22) and (22a), Fig.3 (not shown) and has conical ends with openings (33) and (33a) through which a cable 16 is threaded. The two halves of the housing are joined by means of projecting portions of ribs 24 and 26 which have notches 29 to interlock with end rings 28 of the respective halves. Relative rotation is prevented by engagement of the ribs 24 and 26 with detents 30. The buoyant member 31 may be dispensed with if the housing 23 is made airtight or may be replaced by a malleable foam. The floats are threaded on the cable 16 in end to end relationship Figs. 1 and 2 (not shown) with one tensioning device (15) in each cable. The device (15) is made up in two halves similar to those of the floats, but instead of a buoyant insert a fixed draw screw (35) is provided which engages a threaded fastener (44) attached to a shaft (42). Thus when the device is rotated the shaft (42) is drawn inwardly. Suitable hooks and eyes are provided for attachment to the cable 16. The mode of operation of the invention is illustrated in Figs. 7A to 7G (not shown) and is based on the principal of the float rotating in the orbital flow of the wave and then counter rotating due to the unbalanced weight of entrained water and thus removing the wave crest and transferring water to the trough.

Abstract: 1277167 Making electrical leads AMP Inc 22 Oct 1970 [14 Nov 1969] 50182/70 Heading B3A [Also in Division G4] Apparatus for cutting off a required length of wire includes a motor driven capstan 42 (Fig. 1) feeding the wire from a roll 34, pulses from a pulse generator 52 being counted in a counter 56 as the wire is moved the motor being stopped when the count corresponds to the required length. As described the required length is set up by positioning contacts 154a-154d (Fig. 10) of a first multidecade selector switch 58, numbers corresponding to the length at which the speed of the motor is to be reduced to an intermediate speed and a slow speed being similarly set up on second and third selector switches 60, 62. As the wire is fed the count in binary coded decimal counter 56 of pulses from the generator 52 is decoded to decimal form in decoders 146a-146d the decoded outputs being connected to terminals of the collector switches. When output signals are detected from the four decades of the second selector switch 62 by the enabling of an AND gate the resulting signal on conductor 74 reduces the speed of motor 80 to its intermediate level. In a similar manner when all the outputs of the third and first selector switches are enabled the resulting signals on conductors 76 and 72 respectively slow and stop the motor. Feed rolls 12 (Fig. 1) are then energized to draw a loop of wire 50 resulting from the movement of capstan 42 to a wire processing machine where it is cut and electrical terminals (32), Fig. 6 (not shown), are crimped on to the cut edge by terminal applicators (28, 30). A roller (132), Fig. 8 (not shown), on a bell crank (128) mounted on a pivot pin (13) engages the wire on the capstan to prevent overlap.

Abstract: 1489435 Matrix displays and circuits therefor INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1974 [28 Dec 1973] 53274/74 Heading G5C A driving circuit for a display panel with crossed conductor arrays comprising means for providing two unipolar pulse trains, means to invert selected pulses of the two trains to provide two bipolar pulse trains, which when applied to electrodes of the two arrays respectively produce an A.C. waveform of zero D.C. content across display sites at the intersections of the arrays. A generator 3 provides line scanning pulses A sequentially to the exclusive OR gate 33 of each row electrode where they are combined with pulses B from a square wave generator 25 to produce pulse signal C. This is added to the output, also B, of generator 17 to give output D. Generator 5 provides pulses E to selected column gates 35 where they are combined with the outputs of generators 19, 27 to give output H. The outputs of generators 17, 25 are the complements of generators 19, 27. Thus the combined pulses across a cell, D-H are sufficient to energize it when it is selected, the sign of the voltage reversing each scan period. In other embodiments the signal B has a much higher frequency, e.g. with a pulse duration half that of A; the outputs of the X OR gates may be adjusted to increase the amplitude of signal C to 2V TH  and that across selected cells to 3V TH . Additional h.f. bias may be added to one or both electrode arrays by generator 29, 31. The h.f. signal may be applied only to unselected electrodes to reduce half select effects. Alternatively a l.f. bias may be applied to all electrodes and scanning be done with h.f. signals. The cells may be of liquid crystal or electroluminescent material or gas discharge devices.
