Abstract: 1,222,448. Propelling pencil. MERMAID ENG. CO. Ltd. 4 Nov., 1969 [4 Nov., 1968], No. 52145/68. Heading B6P. A propelling pencil comprises a tube 13, internally threaded at one end, the threads 14 of the tube engaging threads 15 of a cylindrical element 16 formed from plastics and moulded around the end of a wire 31, which wire serves to project the lead (not illustrated). The threads 15 of the element 16 are only on one half of its cylindrical surface. An operating rod 19 is of arcuate cross-section and of such a radius that it will fit between the unthreaded portion of the element 16 and the inner wall of the threaded tube 13 so that rotation of the rod 19 by a knob 20 causes the element 16 also to rotate and hence move axially relatively to the tube 13 and the rod 19. The knob 20 has a gripping piece 22 and a tubular portion 23 of smaller diameter than the rest of the knob 20. The tubular portion is formed with an annular flange 17 at the extremity thereof, which flange co-operates with a circumferential groove 30 formed in a flexibly resilient plastics sleeve 24. The knob 20 and rod 19 are mounted for rotational, non-axial movement by the plastics sleeve 24 which fits over the outside of the tube 13. The sleeve 24 is split by two longitudinally extending diametrically opposed cuts 28 into two jaws 29. The pencil casing 11, when fitted over the end of a tube 33 carried by the sleeve 24, engages with bosses 59 on the jaws 29, so that the jaws 29 grip the knob 20 to prevent its easy rotation. A guide within which the pencil lead is movable longitudinally includes a tube 41 and blade 50 of resilient material of cylindrical shape and formed with conical indentations 51 at its opposite ends. The indentations guide the lead into a puncture 52 extending between the apices 53 of the indentations. The lead is held by the resilience of the material until urged through the puncture by movement of the wire 31 or direct movement of the lead by an external force. Compartments 34 defined by the tube 33 carried by the sleeve 24 are utilized for carrying spare leads. An annular stopper 35 is fitted over the end 38 of an extension tube 36 fitted tightly into the threaded tube 13.

Abstract: 1,249,494. Thermal switches. BRAUN A.G. 4 Nov., 1968 [7 Nov., 1967], No. 52192/68. Heading H1N. A thermally tripped switch for an electric toaster has its trip device moved by a permanent magnet which is normally repelled by a second permanent magnet and moves to unlock the switch when the second permanent magnet moves to a position in which it attracts the first magnet or when a magnetizable member is moved into a gap between the magnets. As shown in Fig. 7b the toast slide 11 extends through a slot 18 in a plate 16 to a guide 20 which supports a shaft 2 having a latch 28 engageable in a recess 29 in a rod 25. As the slide 11 is moved downward an arm 4 on a rotatable magnet 1 strikes a stop 51 and moves the magnet 4 to a position in which it repels a magnet 3 on the shaft to urge the latch 28 to engage in the recess 29. Heating of bimetals 38, 39, 40 in the toasting space will effect movement of a rod 41 to rotate a lever 35 which engages to arm 4 to rotate the magnet 1 to a position in which it attracts the magnet 3 to release the latch 28 and allow the slide 11 and guide 20 to be moved upward by a spring 27. This movement releases contact springs 47, 48 which were held in engagement with fixed contacts 49, 50 by an insulated finger 46 of the guide 20. In an alternative arrangement (Fig. 6) magnet 14 moves toward a fixed magnet 13 when a magnetic member 15 is moved into the gap between the magnets.
