Title: A method and an apparatus for controlling the feeding of a bandsaw blade
IPC: B23D55/06
Filed: 1980-05-29
Abstract: For the better use of the blade of a horizontal bandsaw, the ratio of the speed at which the blade 15 is fed into a workpiece M to the speed at which the blade 15 is driven is kept constant. A bandsaw blade rotating within a pivotable head 5 of a bandsaw is driven by a motor 37, at a speed measured by a tachometer generator 41. The desired speed Vf at which the blade is to be fed into the workpiece M is calculated by a computing unit 51 from a signal from a torque detector 49 and compared, by means of a comparator 53, with the actual blade feeding speed Vf' measured by an angle detector 55 at a pivot of the head 5. If the compared signals differ, a servovalve 61 adjusts the flow of hydraulic fluid to or from a hydraulic motor 33 which controls the rate of descent of the head 5 and therefore the blade feeding speed until the compared signals have the same value. <IMAGE>

Title: Spanner
IPC: B25B13/46
Filed: 1980-07-24
Abstract: The spanner 10 has opposed jaws 14, 16. Each jaw is shaped to form an abutment 24, 34 which in a driving position contacts a pair of opposite nut flats 1, 4 so that, when the spanner is rotated in a forward direction F, the abutments 24, 34 exert torque on the nut 12.   The jaws 14, 16 are both recessed adjacent the abutments 24, 34 so that for reverse spanner rotation the recesses 26, 32 allow the spanner to move round the vertices of the nut until the abutments 24, 34 engage with the next pair of opposite flats 3, 6. The jaw 14 has an outer end extension 28 with an inwardly directed plane surface 30 which contacts the nut 12 on spanner reverse rotation to pull the spanner 10 towards the nut axis. This surface 30 can also be used in conjunction with a parallel surface 36 on the jaw 14 to grip the nut 12 at a different angle to the abutments 24, 34 when the space for spanner movement is restricted. <IMAGE>

Title: Cooling glassware-forming moulds
IPC: C03B9/38
Filed: 1980-10-10
Abstract: Cooling of moulds used for making glass articles, especially receptacles, is carried out by means of cooling members surrounding the mould cooled by a liquid such as water, the cooling members extracting heat by convection or indirect conduction. The rate of cooling is varied from one part of the mould to another to obtain a uniform temperature throughout the article during cooling. This variability is achieved, for example, by disposing between the mould and the cooling member either (1) free spaces of varying thicknesses, (2) spacer members of varying thicknesses, or (3) spacer members of varying thermal conductivities (e.g. Cu or Al). In Fig. 9, the mould exterior comprises two rings 40 which contact the surrounding cooler (not shown) and further rings 41-44 of varying lesser diameters. <IMAGE>

Title: Horizontal shell boiler
IPC: F22B7/06
Filed: 1980-10-16
Abstract: The present invention relates to the application of the fluidised bed combustion process to horizontal shell boilers and provides an arrangement of the thermic syphon tubes 20 which are present within the furnace section 12 of the boiler which separates the vertical and horizontal velocity effects such that the horizontal velocity effect does not cause migration of the fluidised bed material 18. This is accomplished by arranging the thermic syphon tubes 20 such that they are closely spaced along the length of the furnace section 12 and each tube forming a region of overlap in a substantially horizontal direction with directly adjacent tubes so as to define a channel 22 above the overlap regions in which hot gases move horizontally after having risen essentially vertically from the fluidised bed. <IMAGE>
