Title: Milking machines
Inventor: WEHOWSKY GERHARD
IPC: G01F1/684
Filed: 1965-12-18
Abstract: Milk in a pipe (2, Fig. 1, not shown), flows from a milk collecting member (1) in a milking machine past a preheated or precooled thermistor (4) thereby changing the temperature of the thermistor to a certain constant value, and when the flow of milk changes significantly the thermistor tends to assume its original temperature, the corresponding change in resistance being detected in a bridge circuit (Fig. 7, not shown) and used to turn off the machine.  The bridge output is connected to a pair of transistors (15, 17) which operate a relay (19) when the milk flow drops.  The thermistor is carried in a tube (5) which either protrudes into the pipe (2, Figs. 2, 3, not shown), or is situated adjacent the inner wall of the pipe (Figs. 4, 5, not shown), a heating coil (6) being arranged around the tube.

A cooling bed for hot rolled bars and rods comprises a conveyer disposed transversely of the rollway 1 and including a displaceable grate 2 and an interspersing stationary grate 3, the grate 2 being reciprocable horizontally and vertically so that it can lift bars or rods off the stationary grate 3 on which the latter have been deposited at mutually spaced locations, convey the bars or rods and deposit them again on the stationary grate, the stationary grate 3 being longer in the conveyancing direction than the displaceable grate 2 and having a flat bar or rod supporting surface 3a in a region beyond the displaceable grate 2 and the latter having a pusher surface 2a for pushing together and displacing the bars deposited on the flat support surface 3a. The conveyer is lifted by twoarmed levers 6 pivoted to blocks 8 and carrying supporting rollers 7, the levers being operated by push and pull bars 9 and hydraulic motors 10. Reciprocation of the grates 2 is effected by an hydraulic motor 3 and pivot levers 14 mounted in bearing blocks 15 by a common pivot shaft 16, the pivot pins of the levers 14 being guided in vertical holes in the grates 2. The stroke of the motor 13 is adjustable and is selected according to the distance required between the bars deposited on the grate 3. After stroke H has ended the lifted bars are lowered and deposited on the stationary grate 3 in the position 4a. From there they are conveyed further step by step when a new bar 4 is lifted. To produce a strong air current around the bars, large chambers 18 are provided in the foundation below the conveyer. In this way there is formed on the extended grate 3 a group of rolled bars which lie closely adjacent to each other and which are conveyed as a group for further manipulation for example by a chain conveyer 21. In a modification the support surfaces of the grate 2 and the grate 3, except for the extension 3a, are toothed as in Fig. 2 (not shown).

Work-holding and positioning device for use with a bending machine comprises a guide tube carrying detachable clamping jaws which clamp and retain a workpiece, a stop element detachably mounted on the guide tube, and a clamping bush surrounding at least part of the guide tube and having an inner surface engageable with an external surface of the clamping jaws, the clamping bush being axially slidable on the guide tube between a first position in which it clamps the jaws on to the workpiece and a second position where it allows the jaws to be removed from the guide tube, the stop element engaging the clamping bush when the latter is intermediate the first and second positions. The segmented clamping jaws 14 define an internal clamping surface which receives a tubular workpiece 10 and a frusto-conical outer surface 17 which is engaged by a correspondingly tapered surface 18 on a bush 19. The jaws have an inwardly directed flange 15 which enters a groove 16 in the guide tube 11 and are biased apart by springs 20. A collar 21 on the guide tube 11 co-acts with the bore of the clamping bush to form a double - acting fluid cylinder. The bush is moved over the jaws by admitting pressure fluid through the port 24 and is moved away from the jaws, to release a workpiece by admitting fluid through the port 25. The movement of the bush in the latter case is limited by a fork 27 which enters an annular groove 28 in the guide tube. By removing the fork the bush can be moved further to a position 19<SP>1</SP> where it is clear of the jaws to enable them to be exchanged. The guide bush has keyed to it a worm-wheel which is driven by a worm 13 to rotate the workpiece when bends areto be made in different planes. The whole assembly is mounted on a carriage movable parallel to the guide tube axis to position the tube longitudinally in the bending machine.
