Title: Improvements in or relating to devices for testing the thickness of coatings on ferro-magnetic materials
IPC: G01B7/06
Filed: 1944-08-09
Abstract: 575,150. Magnetic tests and measurements. TIMMS, E. S. SPENCER-. Aug. 9, 1944, No. 15189. [Class 37] A device for testing the thickness of coatings on ferromagnetic materials, comprises a permanent magnet mounted on the shorter arm of a steelyard balance so that it can be applied to a specimen under test, the longer arm of the balance carrying a movable counterpoise. When the counterpoise 7 is adjusted so that the lower end of the magnet 5 is just detaching itself from the specimen, a measure is obtained of the least force required to detach the magnet and hence of the thickness of the coating at the place where the magnet is applied. The counterpoise may be adjusted by hand, by arranging it to engage with a helical grove 9 cut on the longer arm 3, its position being fixed at any desired place by a pin 8. The reading of the balance is facilitated by the arbitrarily chosen scale 10. Preferably the magnet is rod-shaped and the lower end is hemispherical.

Abstract: 1,146,780. Brakes for roller conveyers. SEIWES MEKANISKA VERKSTAD A.B. 6 April, 1967 [6 April, 1966], No. 15924/67. Heading B8A. [Also in Divisions F1 and F2] A conveyer roller braking device comprises an air-actuated friction brake 7, Fig. 1, an oscillating disc pump 6 mounted in the roller sleeve 1 with the roller driving the pump, a first brake member 24 movable relative to a stationary shaft 4 into engagement with a second brake member rotatably mounted with the sleeve, the pump drawing in and compressing air in its working chamber and discharging it into a further working chamber 19 in which at least one piston 20 moves to actuate the first brake member, the further working chamber being connected through a further adjustable non-return valve 22 to atmosphere. The pump casing 8 has four axial pistons 9 actuated by the oscillating disc 10 which is driven by the sleeve 1 through a toothed coupling 12 and rotating part 11. Each piston 9 is rigidly secured to a spring-loaded guide piston (13), Fig. 2 (not shown). When the respective piston 9 is reciprocated air passes through its non-return valve 17 via a channel 18 into the working chamber 19 which is common for three or four radially movable pistons 20. A channel 21 leads to the non-return valve 22 adjustable by screw 23. Shoes 24 are pressed into engagement with the inside surface of sleeve 1 with a force dependent on the rotational speed of sleeve 1 and the setting of valve 22. In a modification two groups of radial pistons may be arranged side by side. In another embodiment a braking ring 25, Fig. 3, having a friction ring, rotates with the sleeve 1. A ring 27 which is rotationally stationary is axially movable by pistons 29 into engagement with the friction ring to effect braking. In a modification the axial movement of pistons 29 operate radially movable braking shoes through links.
