Abstract: The present day Current and Potential relays used in conjunction with the thermic protectors on hermetic refrigeration compressors cannot fully meet the requirements for a complete protection and operation. Due to large variations of the voltage conditions and refrigeration demands a great many compressors are burned or damaged yearly. 
     Therefore, it is a general opinion that today's classical "Current and Potential" relays with their "bi-metallic" overloads cannot cope with the problems of the field demands. 
     In the new design:
     1. If the compressor starts properly and attains about 80% of its synchronous speed a low current signal is picked by and electronic circuit of a triac and thus the heavy current path permits the line current of the compressor to continue to pass.   2. In the absence of this singal, no proper start condition, a miniature low current protector is rapidly heated by a PTC (Positiv Temperature Coefficient Thermistor) controlling the start winding and immediately cuts the heavy line current by acting on the triac and thus stopping the compressor.   3. Due to the heat of the PTC this miniature protector remains open for 4-5 minutes thus allowing the compressor motor to restart under the best of refrigeration conditions.

Abstract: An A.C. supply converter of the type described in co-pending British Patent Application No. 80.06636 in which the control of the bidirectional switches connecting each conductor of a polyphase input supply to each conductor of an output supply is effected by a microcomputer, the operation of the program of which is synchronised by interrupt with the input supply. The microcomputer calculates for each output phase 2 values representing pulse widths out of a repeating sequence of 3 (for three phase input and output supplies) and pulse generators produce 3 abutting width modulated pulses in a constant period much shorter than the periods of the supplies. The interrupt operates a software phase locked loop. The pulse generators include an interlock circuit ensuring that the width modulated pulses do not overlap and an overload detector responsive to the turn-on times of the switches. A default logic circuit responsive to hardware or software failure makes the width modulated pulses of equal duration.

Abstract: The very economical padding processes for applying treatment liquids as have become largely established for flat-lying material are also of interest for the dyeing and finishing of tubular textile material. However, before this technology can be used in the latter case it is necessary to take account of the fact that, when circular-knit material is impregnated on a pad-mangle, crease marks are produced on both sides of the tube, which results for example in undesirable hue differences. The apparatus consists essentially of two spreader elements A and B which are at an angle of from 10 to 90 DEG  relative to each other and which are arranged immediately downstream of the point of exit of the tube from the pair of rolls of the pad-mangle, and act on the running textile material from the inside towards the outside. It makes it possible to achieve safe displacement of the creases. The liquor on the textile material is thus given a chance to balance out the undesirable crease marks by migration. <IMAGE>

Abstract: in the production of non-oriented electrical steel sheets, it has been attempted to decrese the watt loss, e.g. by adding Sn into silicon steels, but in such a case the relationship between the watt loss and magnetic flux density falls within the curves 1 and 1' in Fig. 1. The addition of boron is therefore unsatisfactory for meeting the recent demands, for improving the magnetic properties of a non-oriented electrical steel sheet over those indicated by the curve 3. 
     In the present invention, the combined addition Sn with B and/or sol. Al results in development of (110) and (100) textures which are desirable for the magnetic properties. 
     A non-oriented electrical steel sheet according to the present invention, contains 0.015% of C at the highest, from 0.3 to 2.0% of Si, from 0.005 to 0.10% of sol. Al, from 0.02% to 0.20% of Sn, 0.007% of N at the highest, and 0.005% of B at the highest, the weight ratio of B content/N content being from 0.5 to 1.5, said non-oriented electrical sheet being produced by a process comprising an annealing of a hot-rolled steel strip. Instead of B, an appreciable amount of sol. Al may be contained in said sheet, when Mn content is from more than 1.0% to 1.5%.

Title: Improvements relating to apparatus for sharpening chain saw chains

IPC: B23D63/16
Filed: 1984-02-22
Abstract: ® A chain of a chain saw whose theeth are to be sharpened is mounted in a track (4) of a support table so that it can be indexed to a central cutting station whereupon a ram (12) will be actuated to reduce the width of the track (4) and grip the chain. A cutting device will then be lowered into contact with a tooth on the chain so as to sharpen that tooth. When the ram (12) is moved to the open condition the chain is indexed forward again by rotating a pusher arm (8) about a pin whilst the pin carried on its own arm is driven in a forward direction. This causes an angled forked plate (10) to engage behind a tooth facing in one direction only (of the two possible directions). As the pusher (8) is moved back again a pin (29) rides up over a latch (30) onto the top face of the cam (31) so that the plate (10) can ride over the top of subsequent teeth carried by the chain.
