Title: Apparatus for Monitoring the Shape and/or Position of an Article
IPC: B07C5/12
Filed: 1967-10-24
Abstract: 1,185,538. Apparatus for checking article shapes. EMHART ZURICH S.A. Oct. 24, 1967 [Oct. 24, 1966], No.48230/67. Heading G1M. Apparatus for detecting faulty shaped articles such as bottles comprises a conveyer belt 12, Fig. 1, with a plate 20 beneath mounting photoelectric transmitters 24a, 24b, photo-electric receivers 26a, 26b, a light source 28 connected to a light conductor 29 and pilot scanning devices such as transmitter 24p, receiver 26p and a photo-electric transducer 44. Each forward edge of a bottle shortly before the bottle reaches the point 18 interrupts the path of the beam from the pilot scanner and produces a signal from a multiplier tube 44 via light conductor 30p, which signal is pulsed at 48 and passed to a switching stage 50 which produces a gating pulse 49. The output signal of the transducer 44 depends solely on the output of the pilot scanners, whereas the signal of the transducer 42 results from the output from the devices 26a and 26b and only fades if none of the remaining elements 26a, 26b receives light. The pulse 49 is time delayed to appear when the bottle reaches the point 18, and if the article is satisfactory then the beams of all the scanning devices in both the groups are interrupted at this instant so that no signal is provided from conductors 30, tube 42 and gate 52, and the pulse 49 is unable to pass the gate and operate a relay 56. If however one of more of the receiver elements 26a, 26b receives light at this instant then this indicates an incorrectly sized article and a signal appears at the gate 52 via tube 42 simultaneously with the pulse 49, and the relay 56 is excited. The conductors 29 and 30 are light conductive fibre bundles and an accurate determination of the boundary surface 10a of an article is achieved according to the number of beams of light appearing in the plane A or B. The design of the optical part of a single scanner is described with reference to Fig.2 (not shown) and Fig.3 shows a plate 22 carrying position adjustable transmitter elements 24b and 24p together with a desired outline 10a of a bottle in the inspection plane B positioned at the point 18. A tolerance outline shown in dot-dash lines is aligned with the scanning devices at the points on the outline to be checked e.g. the height of the bottle being monitored by element 24h. More than two cross-sections may be monitored if desired and possible oversize as well as undersize may be checked, and the pulse 49 need not be delayed if the scanners are shifted in the direction of travel of the article.

Title: Guided-vehicle systems
IPC: G05D1/02
Filed: 1971-10-22
Abstract: 1373503 Leader gear systems PULSOTRONIC MERTEN KG 22 Oct 1971 [23 Oct 1970 4 Dec 1970] 49230/71 Heading H4U [Also in Divisions G1 and G3] An automatic vehicle guidance system uses a magnetic field generator on the vehicle, the field coacting with a fixed passive conductor to produce an analogue signal that is proportional to the lateral deviation between the vehicle and the conductor and which is used to control the vehicle steering. A proximity sensor Fig. 3 comprises an oscillator I, with temperature compensating NTC resistor R3, producing a high frequency magnetic field that is damped by induced eddy currents in a local conductive material. In the working range of the sensor the output across a feedback winding L<SP>1</SP>, after passing through a filtering and rectification circuit II, is proporttional to the displacement of the sensor from the edge of the conductive material, the output Ua preferably being zero with the sensor and edge aligned.  As used in a vehicle steering control Fig. 7, two such sensors G1, G2 are mounted on the vehicle over the respective edges of an aluminium foil guide, sensor G1 normally being used to control the steering of the vehicle unless its associated edge is not clearly defined, e.g. the guide branches, when contacts a3 of a relay, activated for example by reed contacts adjacent the foil guide, switch over control to sensor G2. The signals from sensor G1 (or G2) pass through amplifier 1 (or 2) ,which has a set zero adjustment. Positive signals pass through diode D3, and amplifiers 3, 5, 8 and 10 to a winding L1 of steering motor M<SP>1</SP>. If the signal from amplifier 3 exceeds a predetermined threshold a trigger Tr activates relay S, which closes contact S<SP>1</SP>, providing an additional signal to winding L 1 to compensate for motor inertia. Negative signals from a sensor pass through diode 4 and similar amplifier and threshold path Tr, 4, 7, 11, 12, this path also being provided with an inverter 6, 7, to motor winding L2. In an alternative, Fig. 10 (not shown), amplifiers 5, 8, 10 and threshold circuit Tr, are used for both signals, with negative signals, which pass through diode D4, amplifier 4, inverter 6, 7, being switchably connected to the amplifier and threshold circuit, and to winding L2. The vehicle may also be provided with a further similar sensor that stops the vehicle if it leaves the foil guide, and means for compensating against variations in sensor output due to change of distance between the sensor and the guide.
