Title: Magnetic testing apparatus
IPC: G01N27/90
Filed: 1971-11-26
Abstract: 1427703 Testing magnetic material BRITISH STEEL CORP 23 Feb 1973 [26 Nov 1971] 55052/71 Heading G1 In an arrangement for testing e.g. power loss in ferromagnetic strip material two arrays of spaced magnetic yokes are provided to reduce errors arising from eddy currents induced during testing in the strip. The sheet e.g. silicon bearing steel is passed through a central slot 8 in a hollow transverse member 6 in which is disposed a former 12 around which coaxial magnetizing solenoid 16 and sensing coil 18 are wound. Two arrays 20, 20' of yokes are provided adjacent each of the opposite faces of the sheet to complete the magnetic circuits including the sheet when solenoid 16 is A.C. energized. Due to the space 24 between the arrays 20, 20', which is greater than the distance between individual yokes, the magnetic circuits on either side of the space are isolated. This isolation produces a breakdown of eddy current induced in the sheet into a number of smaller independent circuits and reduces eddy current losses. The  sensor coil 12 output and a signal representative of current flow in solenoid 16 are combined in a translation circuit to provide a visual indication of power losses and/or used to control the operating conditions of an annealing furnace. The translation circuit is also fed with a signal from a γ-ray sensor measuring the thickness of the sheet and a sensor measuring the width to weight the output of the sensing coil.

Abstract: 1370673 Electrical control systems for IC engines ROBERT BOSCH GmbH 16 Dec 1971 [17 Dec 1970] 58416/71 Heading GIN Overspeed of an I.C. engine, to which fuel is metered by an electronic governor, is prevented by a device which includes a generator having two windings 20, 21 in which are generated signals dependent upon engine speed, and a bistable multi-vibrator, each winding being connected to a respective one of the two inputs of the multi-vibrator so that when the engine reaches a predetermined excessive speed the multivibrator is triggered to produce an output signal for governing down the engine. As shown, the multi-vibrator includes two transistors T10, T11, connected as shown, the winding 20 being connected to the base of T10 via a diode 24 and resistor 25, and to the base of T11 via a diode 26 and RC network 27, 28, and the winding 21 being connected to the base of T10 via a diode 29, which is oppositely poled to the diodes 24, 26, and a RC network 30, 31. A.C. signals are generated in the windings by a multipolar magnetized rotor 23 coupled to the engine crank-shaft. When the engine is operating at speeds below maximum, T10 is conductive and T11 is blocked so that there is a high level output at terminal 15. When the engine speed exceeds its permissible maximum, the negative voltage transmitted to the base of T10 via diode 29 attains a value which cuts off T10. At the same time the positive voltage transmitted to the base of T11 via diode 26 drives T11 into its conductive state causing a low level signal to appear at terminal 15 indicating an overspeed condition. Zener diodes may replace the resistors 27, 30.

Filed: 1969-12-03
Abstract: 1291071 Sampling particulate material B E ARTHUR 3 Dec 1969 59013/69 Heading B8A and B8N In a process for obtaining samples of a particulate material the material is caused to fall in the form of a stream on to an endless belt conveyer at a zone intermediate the two ends of one run of the conveyer, a container is placed on the conveyer upstream of said zone and is moved by the conveyer to a point downstream of said zone, at which point the container is removed from the endless belt conveyer. Apparatus for effecting the process includes a conveyer 1 for transporting particulate material and containers 2 and a chain conveyer 23, including hooks 27, for transporting, depositing and picking up the containers. The chain conveyer 23 including arms 30 having rollers 26 running (Fig. 10) along a trackway 21 (Fig. 10). The chain has horizontal pivots 25 and vertical pivots 24. Each arm 30 pivotally carries a trip hook 27. The hook comprises a body member 28 pivotally connected at 34 to a carrying member 35. A latch member 39 (Fig. 7) is pivotally connected at 40 to the carrying member 35, and includes a toe 41 which is adapted to coact with a detent roller 42. The latch member is urged towards the body member 28 by a compression spring 46 between a member 47 connected to the latch member via a rod 49 and the base of a U-shaped yoke 54 pivotally connected to the body member, the yoke having an aperture through which the rod 49 passes. A roller 67 runs in a guide channel 66 adjacent container deposit and pick-up stations (Figs. 2-4). A roller 44 carried by the latch member, at the deposit stations, engages an arm (60) (Fig. 5, not shown) of a hook tripping mechanism, which causes the latch member to move against bias of spring 46 and releases the toe 41 from the roller 42. The arm (60) may be moved manually 'or automatically out of the path of a roller 44 to permit a hook to pass the mechanism without being tripped. The weight of the container will cause pivoting of the carrying member 35 to a release position (Fig. 10). At a pick-up station a hook engages a bail 2a of a container 2 and the roller 44 runs along a cam 70 (Fig. 10) which returns the members 39, 35 to the position of Fig. 7. The containers are picked-up from a roller table adjacent a sampling station by the hooks 27 (Fig. 3) and deposited on the conveyer 1. They then pass under the shoot 3 (Fig. 2) to a load pick-up station from which they are transported to the roller table at a load deposit station (Fig. 4). The conveyers 1 and 23 may be driven by electric motors, and the motor for conveyer 23 may be of variable speed. The containers may be of metal, plastics, wood or rubber and may be of the same material as the belt conveyer.
