Burnishing.-A tool for polishing or burnishing the edges of heels comprises a plurality of tool elements arranged along and about an axis, the elements being independently adjustable transversely of the axis to give a predetermined contour to the tool. The same set of elements can thus treat all shapes of heels. A rotating shaft 8 carries a hub 22 into which are screwed a number of rods 26 arranged equidistant from the axis and each other. A second hub 32 carries sleeves 36, which slide over the rods 26. Each sleeve carries a number of tool elements 50, 52 loosely pivoted the sleeve and formed with heads 54. A templet 58 is formed with grooves engaging the heads, the grooves being so shaped as to cause the tails of the elements to stand at various distances from the axis so that the whole tool conforms to the heel for which the templet is designed. The ends of the grooves are arranged to withdraw unnecessary tools out of action, e.g. in the case of low heels. The elements near the end of the tool are backed off so that they can deal with abrupt curves. The templet is secured to the shaft 8 by a conical screw engaging the expansible end of the shaft, and the hub 32, is secured to the templet. The shaft 8 is oscillated axially by a. cam 14 engaging a fixed roll. To heat the tool each of the hubs is engaged by a plate, 69, 78, respectively, formed with sockets for electric heaters and yieldingly pressed against the hubs by springs to allow of axial reciprocation of the tool.

Title: Composite collector load for class a semiconductor amplifier
IPC: H03F1/22
Filed: 1977-04-21
Abstract: 1527293 Transistor amplifiers K GARWELL 21 April 1977 [23 April 1976] 16467/76 Heading H3T The efficiency of a class A transistor amplifier TR1 is increased by providing a second transistor TR2 as collector load together with a switching- diode D connected between the transistors. With a negative going input signal the rising collector voltage of TR1 blocks diode D2 and current flows into the load ZL through transistor TR2. With a positive going input signal, TR2 turns off and current flows from load ZL through D and TRI. Since the output current does not flow through resistor R, this resistor can be larger than if it forms the whole collector load and less power is wasted. A detailed circuit of an audio amplifier incorporating the invention is described, Fig. 5 (not shown).
