Apparatus for forming a tunnel comprises a tubular shield 1 movable along the tunnel, and a tunnel cutting machine 2 fixed in the shield and having a boom 4 with a rotary cutting head 5, the boom being mounted so as to be universally-pivotable and its movement being automatically controlled so that a cam follower on the boom is continually urged into engagement with a cam on the shield having a profile corresponding to that to be cut. The boom 4 is mounted on brackets 6 and is pivoted about a horizontal axis 7 by rams 8, the brackets 6 being carried on a turntable 10 rotated by rams 11 for pivoting the boom laterally. The boom 4 and the drive shaft for the head 5 are telescopic, their movement being effected by a ram or rams. A scraper conveyor 14 carries material from the front of the machine, the material being swept up a ramp 20 to the conveyor by an auger 21 rotating with the head 5. The shield carries a part-circular guideway 22 supporting a winch 23 for hoisting concrete wall sections 24 up the guideway, and it carries rams 25 for pressing against the end face of the wall to advance the shield. The rams 8, 11 may be controlled manually and the rams 25 may be used to steer the shield. Instead of the boom being telescopic the turntable may be displaceable fore and aft.

Abstract: 1,173,697. Continuous muffle furnaces. T. S. ALLDEN (Indiana General Corp.) 22 Dec., 967, No. 58515/67. Heading F4B. [Also in Division H1]. Apparatus for producing miniature fired ferrite bodies comprises a moulding device feeding a shoot leading to a conveyer 30 passing into and through a continuous, miniature muffle furnace 40, means for supplying inert gas at the exit end thereof, means for supplying air towards the entry end; means for extracting atmosphere gas from about the middle of said muffle and means for conveying ferrites from the conveyer to a testing device. Ferrite core bodies ejected from the moulding device are propelled by air from a jet 11 into the feed shoot (Fig. 8) which deposits them as a single layer on the conveyer 30. The muffle 45 is supplied with air through a tube 64 having an exit port 67 and with inert gas, e.g. N 2 , Ar, CO 2  or water vapour, through a chamber 59 at the exit end, and a vacuum tube with a port 69 in the middle region exhausts the gaseous atmospheres.

The conveyer 30 is a flexible mesh belt made of Pt-10% Rh alloy, its wheels 31, 32 being driven by a motor 33 through speed reducers 34, 37, a coupling 35 and shaft 36. After bearing the belt the treated ferrites pass down a shoot (90, Fig. 6) to a testing device similar to that disclosed in U.S. Specification 3,060,376. The ferrites, which have an outside diameter of 0À020-0À050 inch and an inside diameter of 0À013-0À030 inch, are heated to about 1500‹ C. the introduced air burning out the binder and the inert gas preventing reoxidation.

Patent GB-2006158-A (GB)
Title: Hollow boom construction amd method of forming boom
IPC: B66C23/697
Filed: 1978-09-13
Abstract: The invention relates to boom constructions of polygonal cross-section for cranes and has particular application to multi-section booms in which one section is telescoped with another. Storage of booms and components therefor can be a problem where particular dimensions of boom are required at short notice. The present invention simplifies the construction of booms by the provision of corner sections 30 therefor having recesses to which cent longitudinal edges of adjacent plates 32, 34 can be secured. By securing plates 34 to the inside of two corner sections 30, the boom may be built up in stages with the last one or two plates 32 being secured to the outside of unconnected corner sections 30. Reinforcement of the boom may also be facilitated by the use of corner sections, which concentrate strength at the regions where greatest stress will occur, particularly in booms of rectangular or square cross-section. <IMAGE>

Title: Machine for aiding radiator repairs
IPC: F28F9/02
Filed: 1978-11-30
Abstract: In place of the traditional soldered connection between the tanks and the core block, some radiators, particularly motor vehicle radiators, are being manufactured with a connection having a rubber gasket 9 which is compressed, and the connection rendered mechanically sound, by bending a series of tabs 15 over onto a ledge (14) on a bead (13) of the tank cover 7. It is so troublesome to dismantle such a connection without damage that such radiators have been discarded rather than repaired. The invention provides a machine in which a tool, Fig. 2 (not shown), traverses along the series of tabs, imparting a twisting motion to the tabs to bend them all back. The tool may be likened, in shape and in action, to a plough, in that only a simple straight line traverse is effective to provide the twisting motion. The traversing may be effected by coupling the tool to a saddle 18 mounted on a lead screw 19 of the machine. <IMAGE>
