Title: Surface Defect Detecting Apparatus for Round or Cylindrical Metallic Material
IPC: B21B38/00
Filed: 1979-02-09
Abstract: Surface defect detecting apparatus comprises at least one non- contacting eddy current flaw detecting sensor (3) mounted on a cylindrical member (2) rotatable at constant speed. Cylindrical metallic material (1) is fed at constant speed axially into the member (2), whereby its outer surface is spirally scanned for surface defects by the sensor (3). The length of feed of workpiece (1) and the angle of rotation of the cylindrical member (2) are measured by detectors (15, 13). The size and location of a flaw is registered by an output dependent on the signals from the sensors (3), length measuring means (15) and turning angle detector (13). The cylindrical member (2) is autocratically adjusted vertically and horizontally to reduce any eccentricity relative to the workpiece in response to signals from a distance sensor (11 Fig. 3) for measuring the gap between the sensors (3) and the workpiece (1), and from the turning angle detector (13). An automatic gain control circuit responsive to signals from the distance sensor (11) controls the detection signal level from sensor (10) Fig. 1 in accordance with changes in the gap. <IMAGE>

Title: Load-dependent Proportioning Valves for Brakes
IPC: B60T8/30
Filed: 1980-09-24
Abstract: In a load-dependent proportioning valve 1, increase in input pressure P1 results in corresponding increase in output pressure P2 until the force of a load- dependent spring 12 is overcome by the pressure on a control piston 8 whereupon output pressure P2 begins to increase as a first proportion of input pressure P1 (at points A,A', Fig. 2, depending on the compression on spring 12 caused by a load): further increase in input pressure and, proportionally of output pressure then causes movement of an annular piston 16 against a spring biased against the control piston 8, until the piston 16 abuts a shoulder 17 whereupon the output pressure P2 begins to increase as a second proportion of the input pressure P1 (at points B,B'). Additionally, in further embodiments, the valve similarly includes a further annular piston to provide for an increase in output pressure as a third proportion of input pressure. <IMAGE>

Patent GB-803913-A (GB)
Abstract: 803,913. Endless conveyers for handling batches of articles. WALL & SONS Ltd., T. Feb. 20, 1956 [Feb. 25, 1955], No. 5788/55. Class 78 (1). [Also in Group XIII] A conveyer for transporting cardboard containers which are to be supplied with liquid confection and then passed through a freezing chamber 25 consists of a pair of endless chains 1 to which successive pairs of opposed gripping frames 12, 14, 12<SP>1</SP>, 14<SP>1</SP> are attached by brackets 8, 9 which are mounted together with spacers 7 on cross rods 6 extending between opposed pivot pins of the chains. The frames 12, 121 each include a plurality of triangular notches 13 for receiving triangular cardboard containers, while the frames 14, 14<SP>1</SP> are arranged to co-operate with the frames 12, 12<SP>1</SP> on the straight runs of the conveyer to form mating pairs 12, 14<SP>1</SP> and 12<SP>1</SP>, 14 between each of which a batch of containers is gripped. In order that feeding and discharge of the containers may take place at the same end of the conveyer, i.e. outside the chamber 25, the ends of the conveyer are supported by sprockets 15, 16, each of which are provided with alternate deep and shallow depressions between their teeth so that only alternate pivot pins of the chains are engaged in the shallow depressions and the links between these pins are aligned. Also, the sprocket pairs are orientated such that pivot pins of the chains engaging shallow depressions in one sprocket pair lie in deep depressions in the other sprocket pair. As a result the frames of each of the pairs 12, 14<SP>1</SP> and 12<SP>1</SP>, 14 which retains a batch of containers remain face-toface at the end of the conveyer within the chamber 25 but open at an acute angle at the end of the conveyer outside the chamber to discharge the frozen confections by gravity at 28 and allow empty containers to be inserted between them at 27. The conveyer is driven step-by-step so that each batch of empty containers passes below a set of filling nozzles 26 for filling them with liquid confection prior to entering the freezing chamber. Specification 732,434, [Group XVII], is referred to.
