Title: Programmable distance measuring instrument
IPC: G01C22/02
Filed: 1972-10-10
Abstract: 1403028 Pulse rate multipliers PENTRON INDUSTRIES Inc 10 Oct 1972 [1 Nov 1971] 46626/72 Heading G4D An electronic distance measuring instrument receives pulses representing an increment of distance or length and generates a preselectable number of clock pulses for each distance pulse, the clock pulses being counted. The system described measures the distance travelled by a vehicle in yards and feet. Displacement pulses are generated from the vehicle wheel either optically or magnetically and are cleaned and shaped by amplifier and noise filter 110, Schmitt trigger 116 and monostable 118. Calibration.-Calibration switch 156 is set to the ON position, the counters are reset and the vehicle is driven for an accurately known distance (say 1000 ft.). The reading in counter 158 is taken and from this the distance travelled per distance pulse (X ft.) is calculated. The value 1000X is then set into programme switches 144. Operation.-The counters are reset. With the reset and calibrate switches in the off position, flip-flop 126 is set by the first distance pulse. Gate 130 is enabled feeding pulses from oscillator 132 to 3-stage decade counter 136. Counter 138 is enabled by removal of the reset signal on line 140 and counts up oscillator pulses until the value set in the programme switches 144 is reached when flip-flop 126 is reset via gate 146. Each time the count in counter 136 reaches 999, the next pulse resets the counter and feeds an output pulse to 4-stage decade counter 158 and optionally to a printer. These output pulses correspond to 1 foot of displacement. Carry over gate detectors 162 detect a count of 279 in the foot counter, reset it on arrival of the next pulse and pass a pulse on to the low stage miles counter.

Abstract: 1,245,370. Lap forming device. CROMPTON & KNOWLES CORP. 29 Sept., 1969 [23 Oct., 1968], No. 47717/69. Heading DIN. [Also in Division G3] Textile fibres are withdrawn from an enclosure by rolls to form a lap and the average density of the fibres in the enclosure automatically controls the drive of means stuffing fibres into the enclosure so as to maintain density in the enclosure constant. In Fig. 2, textile fibres supplied by an elevator conveyor (not shown) are deposited into a chute 34 which is kept full with overspill returned to the conveyor through chute 35. Stuffing rolls 40 press the fibres from chute 34 into an enclosure 46, having a vibrating wall 38, from which a lap is withdrawn by rolls 48 and 18 for transmission to a carding machine and can coiler (not shown). Light from one or a number of lamps 60 passes through transparent or translucent dustproof housings, and the fibres in enclosure 46, to a number of photocells 54 arranged across the width of the enclosure so that an electrical signal representative of the average density is obtainable to control the speed of an electric motor (not shown) driving rolls 40 and thus maintain density constant. The control of speed is effected. by comparing the amplified photocell output with a reference voltage so that any difference adjusts the firing point of a silicon controlled rectifier in the motor armature circuit. Upon operation of a switch (not shown) to render automatic control ineffective, motor speed may be controlled manually through the SCR firing circuit which is supplied with feedback in dependence on motor speed.

Abstract: 1,090,070. Regulating conveyed articles. JAGENBERG WERKE A.G. Nov. 12, 1965 [Dec. 24, 1964], No. 48091/65. Headings B8A and B8S. Articles 2 travelling on a conveyer belt 1 have their spacing regulated by a series of members 3 each freely pivotally mounted on the conveyer frame at 4. As shown, when for any reason the leading article 2 is held momentarily from proceeding, it causes the leading ends of its associated pairs of members 3 to be spaced apart. The trailing ends thus form a stop for the following article and all succeeding articles are similarly stopped. The tendency for " bunching " of the articles is thus eliminated. In a modification (Fig. 8, not shown), the conveyer may simply comprise an inclined surface on which the articles 2 roll. Instead of the articles (which may be bottles having a downwardly tapered form) being positively stopped, the tendency to bunch may result from the braking action of a feed worm (Figs. 6, 7, not shown). The invention may be applied to stopping a stream of bottles on an endless belt prior to pick-up by a suction head (Fig. 5, not shown).
