Abstract: 1,063,355. Hair drying brush and comb combination. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Feb. 4, 1966, No. 4986/66. Headings A4K and A4V. [Also in Division A5] A hair treatment device, designed to be supplied with hot air from an electric hair dryer through a hose, comprises a combined brush and comb unit mounted in a housing of the device, the mounting being such that rotation of the unit selectively brings either brush or comb into an operative position. As illustrated in Fig. 1, the device comprises a sleeve-like casing member 1, adapted for connection to the hot air blower tube (not shown) of an electric hair dryer (not shown), and a brush and comb unit which is mounted at the ends 7 and 8 of its spindle member 4 so as to be rotatable. The unit, which normally is biased by spring 9 so that a surface at end 8 of the spindle member cooperates with internal end surface 10 of the casing member to prevent rotation, is released for rotation by axial displacement, for example by depression of knob 12 to oppose the action of the spring. The spindle member carries comb teeth 5 and brush bristles 6 on its opposed faces, as illustrated, and has hot air discharge openings, for example longitudinal slots, extending therethrough, as illustrated in Figs. 2 and 3 (not shown); rotation of the spindle member through 180 degrees selectively brings the brush or the comb into the operative position. Rotation through 90 degrees brings a flattened key portion of the spindle member into line with an open slot in the bearing mounting at end 8 of the spindle member and hence allows removal of the brush and comb unit from the housing.

Abstract: 546,838. Indicating apparatus. SIGMA INSTRUMENT CO., Ltd., LOXHAM, J., and BOOSEY, F. April 25, 1941, No. 5393. [Classes 106 (ii) and 106 (iv)] Relates to instruments in which a plunger is moved against for instance a spring the resistance of which varies with the movement, and consists in providing the mechanism with a plate of magnetic material opposing a magnet relative movement between plate and magnet taking place in unison with the movement of the plunger to keep the resistance to movement constant. The invention is described as applied to the comparator set out in Specification 542,231. The moving and fixed rings C, A, are provided with lath springs D, B. The plunger E adapted to be raised by the work is urged downwards by a spring not shown and terminates in a plate F. The moving ring C is held against its ball bearing track by a spring L which has a downward component. The poles H and J of a magnet act on a keeper K attached to the moving ring C and urge the latter upwards until the pin G engages under the plate F. As the ring C moves upward the lath springs B, D are twisted and resist movement of the ring with a force increasing with the angle of twist. But the gap between keeper and the magnet poles lessens and the magnet exerts a correspondingly greater force. Suitable proportioning ensures that the force between the pin G and plate F can be kept substantially constant throughout the range of the instrument.
