Abstract: 1401278 Disc brakes AUTOMOTIVE PRODUCTS Ltd 15 Sept 1972 [27 Sept 1971] 44921/71 Heading F2E A disc brake comprises a fluid pressure actuated operating member, e.g. a piston 13, having a replaceable disc pad 14 and a releasable one way holding device acting through a lost motion connection to permit unrestricted movement of the operating member in the brake applying direction and to oppose movement beyond that necessary for brake release of the operating member in the brake release direction, the lost motion connection permitting the brake release movement. The one way holding means includes an annular member 28 mounted within the piston for limited movement relative thereto to provide the lost motion connection, the movement being limited in one direction by cooperation of pins 30 of the annular member with one end of slots 27 of the operating member and in the other direction by a shoulder 24 of the operating member. A rod 20 is rigidly connected to the brake housing and projects through the annular member 28, tapered cavities 33 being provided therebetween. A ball 34 is mounted in each cavity and provides a wedging action on brake release movement of the operating member after the lost motion connection has been taken up. Elongate arcuate sectioned grooves 38 are also provided in the rod 20 so that, on rotation of the operating member the balls 34 co-operate with the grooves 38 to allow the operating member and annular member assembly to be moved rearwardly in the housing. The balls are urged inwardly of the annular member 28 by a spring 35. The end of the rod 20 adjacent the housing is tapered to facilitate movement of the operating member and annular member assembly back to an operative position after a pad has been changed.

Alternatively the material can be one hardenable by quantitative or qualitative change of the contained plasticizer and the hardening effected by oil treatment. The expanding means may be held in position within the tube by magnetic means or by an external toroidal device positioned behind the sphere 8. The vehicle includes driving means and may alternatively consist of a plurality of separate carriages linked together and it may be preceded by trench digging apparatus. Means may also be provided for testing the hardness of the conduit as it leaves the guide 15 and such means can be associated with a suitable feedback network for controlling the speed of the vehicle, the ternperature or flow of the medium or the feed of the conduit to maintain the necessary hardness of the conduit.

Title: Device for forming a strip helically into a pipe
IPC: B21C37/12
Filed: 1971-09-29
Abstract: 1357167 Coiling strip to form a tube BLOHM & VOSS AG 29 Sept 1971 [30 Oct 1970] 45287/71 Headings B3E and B3A A device for forming a strip helically into a pipe comprises an internal bending roll 10, Fig. 1, and two external bending rolls (30), 31, Fig. 3, the bending rolls being movable during forming of the pipe in a direction radially of their longitudinal axes, and sensing means for measuring deviations of the diameter of the formed pipe from a desired pipe diameter and moving the internal bending roll and/or the external bending rolls radially so as to compensate for the measured deviations. The internal bending roll 10 comprises a carrier 12 and rollers 11 and a bearing holder 13 supports the carrier 12 for axial displacement by means of a toothed rack 21 and drive 22. The holder 13 is adjustable vertically by displaceable wedge drives 15 and the carrier 12 is positioned horizontally by a slope measuring device 20 which actuates a motor 19 to rotate an eccentric shaft 18 mounted on a support 14<SP>1</SP> of the holder 13. The carrier 12 also carries a support 23 having rollers 25, Fig. 2, which press against the inner wall of the tube. The external bending rolls (30), 31 each comprise a carrier and rollers 32, each carrier being displaceable vertically by movement of a wedge 35 relative to a wedge 33 and displaceable axially by the simultaneous movement of both wedges. The wedges 33 also have wedge drives mounted on their sides to effect horizontal displacement of the outer roll carriers. The rollers 11 and 32 can be moved angularly relative to their carriers to allow for small variations in the angle of feed of the strip. A curvature sensing device (17, Fig. 4) is coupled to a control circuit which controls drive 16 to change the height of roll 10 to correct constantly any deviations from a desired diameter. The sensor may also be coupled to the rolls (30), 31.

Abstract: 1,122,876. Centrifugal separators; liquid filter. DONALDSON CO. Inc. 11 Oct., 1966 [14 Oct., 1965], No. 45338/66. Headings BID and B2P. A liquid filter, e.g. for treating coolant for machine tools, comprises a first housing 10 having one or more centrifugal separator elements 15, Fig. 1, an inlet pipe 17 for liquid to be treated, an outlet pipe 16 for clean liquid and liquid underflow outlet pipe 18 and a second housing 52 in communication with the first housing by means of the outlet pipe 18 and incorporating a pervious filter element 59, a restriction device 63 being provided in the underflow path, e.g. as shown at the end of a clean liquid outlet pipe 62 for filtered liquid leaving the housing 52, for regulating the amount of underflow and so as to limit the re-entrainment of particles separated from the liquid in the first housing 10 back into the centrifugal separator element or elements 15. The housings 10 and 52 are attached by brackets 14 and 53 respectively to a supporting device 13. The separator elements 15 are mounted between partitions 30 and 31 in an upper portion 11 of the housing 10. Each element 15, Fig. 3, consists of a tube 40 having a lower frusto-conical portion 42, a vortex finder 41 for the discharge of centrifuged liquid, and helical blades 45, 46 for whirling the liquid to be cleaned as it enters the annular inlet 44 in the tube 40. The portion 11 of the housing is flanged at 20 to form an elliptical cover to which is connected the lower portion 12 of the housing in the form of a detachable container into which the underflow from the separator elements 15 discharges the solid particles settling to the bottom of the container. The underflow liquid with some entrained particles leaves through the outlet pipe 18. A drain plug 26 is provided in the container 12 to drain the liquid in the container to the level of the plug to allow the container to be raised, rotated through 90‹ and tilted so that it can be detached for cleaning. The housing 52 has a similar elliptical cover 51 from which the housing can be quickly disengaged in a manner similar to that explained for container 12. The underflow liquid from the pipe 18 flows via a tube 61 to the bottom of the housing 52 where the heavier solid particles settle out. The liquid then passes through the filter element 59 and the filtered liquid leaves through a perforated tube 55 and the outlet pipe 62. The filter element is secured to the tube 55 by means of a screw 58 and may consist of a filtering member in the form of pervious metallic cylinders supported between discshaped plates with pleated filtering material between the cylinders. The restriction device 63, which may be detachable, has an orifice 64 the size of which is determined by the amount of underflow desired in the system. The underflow is usually limited to approximately 0.3 to 5.0% of the total flow through the filter.

Abstract: 1,020,763. Radar. ALBISWERK ZURICH A.G. Dec. 7, 1962 [Dec. 8, 1961], No. 46226/62. Heading H4D. [Also in Division H1] A waveguide junction forming part of the TR apparatus of a distance-measuring device comprises co-linear circular and rectangular waveguides 20, 23 and a third waveguide 22 having its axis at rightangles to the common axis and inclined at a small angle # to the short side of the rectangular guide. The arrangement is such that the third waveguide 22 picks up a small fraction of the continuous signal transmitted from the rectangular waveguide towards the antenna, but picks up the major portion of the received signal which is polarized at right-angles to the transmitted signal. The waveguide 22 forms the feed of a receiver in which the transmitted and received signals are mixed. Instead of waveguide 22, a probe may be used, but in this case it is necessary to re-orientate the waveguide 21 so that the probe makes a small angle with the major, instead of the minor, axis of the guide.
