Title: Improvements in and relating to internal shoe drum brakes
Inventor: CHOUINGS LESLIE CYRIL
IPC: F16D51/24
Filed: 1965-07-06
Abstract: 1,096,648. Internal shoe drum brakes. AUTOMOTIVE PRODUCTS CO. Ltd. July 5, 1966 [July 6, 1965], No. 28640/65. Heading F2E. An internal shoe drum brake of the duoservo type has a yieldable abutment engagoable with the end of the secondary shoe adjacent the actuating cylinder, the abutment being arranged to yield at a predetermined braking torque such as to allow the shoe assembly to move to a position in which further increase in braking is obtained by trailing shoe action. For this purpose, one of the pistons 10 in the actuating cylinder 8 is formed with a shoulder 15 acting as a stop whereby movement of the shoe assembly will cause the end of the primary shoe 2 adjacent cylinder 8 to be anchored and the shoe 2 thus to act as a trailing shoe. The yieldable abutment consists of a pin 16 on a lever 18 pivoted and 19 and acted on by a spring 20, the pin engaging in a slot 17 in an enlarged end of the other piston 11. A stop 20a limits movement of the lever 18. At a predetermined braking torque the pin 16 yields so that both pistons move to the left until the shoulder 15 engages the cylinder. Alternative applying means comprises a link 22 and lever 23 acted on by hand brake linkage (not shown).

Abstract: 871,640. Interferometers. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 21, 1959 [Aug. 30, 1958], No. 28641/59. Class 97(1) A Fabry-Perot type interferometer has a pair of plate-mounting assemblies each comprising a part carrying means for joining the two assemblies, and a second plate-carrying part connected with the first part by an elastic member and means for deforming said member in the one assembly for adjusting the plane of the plate and in the other for adjusting the separation of the plates. Fig. 3 shows an axial section of one assembly comprising a ring 7 connected by a membranelike portion 11 to an inner ring 9 which acts as a bearing for the tube 13 in which is mounted a plate 12. At three points on the outer ring 7 defining an equilateral triangle are secured springs 14 bearing at A against the inner portion, the pressure being adjustable by means of the screws 15 to vary slightly the tilt of the inner portion as the membranelike wall 11 is stressed. The inner portion 8 of the other assembly of the pair shown in perspective in Fig. 4 also supports a plate 16, and is capable of slight axial movement under pressure applied at diametrically-opposite regions B, B<SP>1</SP> by the yoke 17 which is secured to a clamped torsion bar 18 whereby a movement of 21 may be transmitted with reduced amplitude at B, B<SP>1</SP>. The yoke 17 may bear directly against the inner ring as shown, or, if greater control and stability are required, through a bent spring.. The two assemblies 1, 2 may be joined as in Fig. 1 the nuts 4 and 5 being adjusted for approximate parallelism of the plates. The pair of assemblies is mounted on a general supporting device, the fixing means being in the same plane as that containing the axis of the system and B, B<SP>1</SP>, in order that the reactions of the fixing point under the stress of the yoke 17 produce no unsymmetrical strains.
