Title: Delta modulation signal transmission systems
IPC: H03M3/02
Filed: 1971-05-07
Abstract: 1306643 Delta modulation systems WESTERN ELECTRIC CO Inc 7 May 1971 [8 May 1970] 13752/71 Heading G4H In a delta modulator in which a " 1 " bit is transmitted by a bi-stable 14 in transmitter 10 to a receiver 11 whenever the input signal 29 exceeds a feedback signal from integrator 17, the size of the incremental step of the integrator 17 is increased when a predetermined number of consecutive similar bits have been transmitted to the receiver by bi-stable 14 and decreased when a predetermined number of consecutive bits are different from the one before. The step size is also increased or decreased in response to a smaller number of consecutive similar bits or consecutive different bits when the last step change was in response to consecutive alternating bits or consecutive similar bits respectively.  As described the output of bi-stable 14 as well as being connected to the receiver is connected via a resistor network 16 to the integrator 17 the integrator output being compared in a clocked differential amplifier 30 with the analogue input 29. The bi-stable output is compared in a comparator 46 with the state of the bistable of the previous clock pulse (this being stored in a further bi-stable 37), counters 58 or 54 being stepped in accordance with whether the states are identical or not respectively. When one of the counters reaches a count of 6 an overflow pulse increments or decrements a further counter 62 to increase or decrease the signal applied to the resistor network 26 and so increase or decrease the incremental step. The overflow pulse is also applied to a bi-stable 66 which enables the counter which has not overflowed to overflow after a lesser number of input pulses are applied to it. At the receiver the transmitted pulses are received by a bi-stable 73 and fed via a resistor network 71 (controlled in a similar manner to that of the transmitter) to integrator 72 and output line 77.

Filed: 1947-05-28
Abstract: 623,886. Harvesting root-crops. JOHNSON. T. S. May 28, 1947, No. 14235. [Class 6(iii)] In a potato-digging machine the material excavated by the shares 6 is discharged on to the inclined surface of an upwardly - travelling conveyer 13 3 and passes therefrom on to a discharge conveyer 26 across an adjustable gap which permits stones, earth and small potatoes to fall therethrough. The excavated material is first conveyed rearwardly by a conveyer 8 which discharges on to a wide-mesh conveyer 9. Potatoes and stones fall through the mesh, but haulms, retained on the conveyer, are discharged rearwardly. A short transverse conveyer 10 receives the discharge from the conveyer 9 and in turn discharges on to an elevator 11 which includes raised bars 12 at intervals. From the top of the elevator 11 the material falls on to. the upwardly-travelling, inclined surface of a slat conveyer 13, down which potatoes, stones and earth roll, the irregular stones becoming wedged between the slats and being discharged over the top of the conveyer. From the base of the conveyer 13, the remaining material passes across a gap (see Fig. 2) to a final conveyer 26 arranged to discharge potatoes laterally to a bagging point or to a cart. The gap is adjustable by moving the lower roller 17 of the conveyer 13 along a slot and permits potatoes and stones below a predetermined size to fall therethrough. Operators may stand adjacent to the discharge end of the final conveyer to remove unbroken lumps of earth. All the conveyers, which are of openwork construction, are driven from a shaft 3 coupled to the power take-off of the towing vehicle. Material falling through the conveyer 13 enters a wire basket 20 the base 21 of which can be opened periodically to deposit trash on the ground: Spring-loaded flaps 14 are provided adjacent to the top of the conveyer 13.
