Abstract: 823,473. Hair driers. SOC. DE VENTILATION ET D'ELECTRICITE APPLIQUEES V.E.L.E.C.T.A. July 24, 1957 [July 26, 1956], No. 23423/57. Class 81 (2). A hair drier has two humidity detectors, one influenced by the air passing through the hair and the other by ambient air so that when the indications of the two are equal it is known that drying is complete. In one form a fan 3, driven by a motor 4, circulates air through the hair and part of the returned air passes through a humidity detector 8a. At the same time external air is drawn in through a duct 9 and over a similar detector 8b and owing to the juxtapositioning of the two detectors the temperature of the two air streams is approximately equal. The two detectors are connected in an electrical bridge circuit and the motor is automatically switched off when a balance is reached. In another form used air is withdrawn at the output of the fan and, after cooling to atmospheric temperature in a spiral tube, it is passed through a metal tube in contact with a second metal tube through which ambient air is passed. Each tube encloses a humidity detector which again effect stopping of the motor when a balance is reached.

Title: Improved disc brake for vehicles
IPC: F16D65/46
Filed: 1951-10-11
Abstract: 712,534. Disc brakes. DUNLOP RUBBER CO.. Ltd.. and BUTLER, H. J. Oct. 7. 1952 [Oct. 11, 1951. Nov. 16, 1951; March 6, 1952]. Nos. 23647/51, 26854/51 and 5820/52. Class 103(1) The invention relates to a number of forms of vehicle disc brakes which are of light weight and may be produced cheaply, the main common feature of the various forms of construction being that the pads are pressed in to engagement with each side of a single brake disc and are carried by pressure plates axially aligned on each side of the disc and having their major axes normal to a radius of the disc, and substantially bisected thereby. In the brake shown in Figs. 1 and 2. the friction pads 7 are carried by channel shaped pressure plates 5 and 6 one pair of ends of which are pivotally connected by pins 15 to a rod 14 and by swivel couplings to plates 8 linked to a non-rotatable torque arm 2. The other pair of ends are normally pressed apart by a volute spring 21, the release movement being limited by a member 18 which is under constant torque by a clock-type spring 19, the action of which in co-operation with a Belleville washer 20 acts to preserve a constant release clearance between the pads 7 and the disc 1. The brake may be applied by mechanical means exerting a force on connection 32 pivoted to the end of lever 27 or by fluid pressure acting in cylinder 28 on piston 29. Movement of lever 27 exerts through pull rod 23 a force tending to press pressure plate 5 towards the disc and through boss 17 a force acting similarly on pressure plate 6. A coil spring 26 on rod 23 tends at all times to screw it into sleeve 22 so as to keep its head 24 in tight engagement with plate 5. As shown in Fig. 1, the plate 6 is provided with a number of enlarged channel parts 33 in any of which it is possible to position the actuator cylinder 28 so as to obtain different leverage ratios. In the construction shown in Figs. 6 and 7, the pressure plates 40, 41 are similarly closed upon the disc 38 either by direct mechanical action or by the fluid pressure piston and cylinder 54, 55, the force on plate 41 being applied through a rod 60 and sleeve 62 which is kept tightly screwed thereon by a pre-tensioned spring 64. In this arrangement the torque arm 51 as a swivelling connection with a slot 50 at the centre of pressure plate 40. In the arrangement shown in Figs. 9 and 10 the fluid pressure actuator acts through a rod 83 connecting the apices of two V- shaped axially aligned pressure plates 74 and 75, the lower ends of the plates having a swivelling connection with the part spherical ends of a pin 78 passing through the hollow torque plate 76. A further embodiment. somewhat similar to that shown in Fig. 2' is also described, the fluid pressure cylinder and piston acting upon the pressure plates on each side of the disc through a piston rod passing through a hollow sleeve connecting the two plates. Specification 712,537 is referred to.
