Abstract: The present invention discloses a pad retaining plate assembly for use in retaining a brake pad on a brake shoe. Certain brake shoes utilise a brake pad formed with a dovetail formation on its rear surface so that the pad can be slid into a complementary recess (31) provided in a face of the brake shoe (1), the recess (31) being closed at one end and open at the other to allow for pad replacement. A pad retaining plate assembly (3) typically comprises a latch member (5) which obstructs the open end of the recess (31). However, such assemblies are difficult to remove to facilitate pad replacement. 
     The present invention provides a pad retaining plate assembly (3) which can be operated to allow for pad replacement without any part having to be removed and without the inconvenience of having to deal with nuts, bolts, etc. The pad retaining plate assembly (3) comprises a latch member (5) which is movable relative to a guide (7), the guide (7) being secured to a brake shoe (1) so that the latch member (5) can then attain an operative position wherein the latch member (5) projects through an aperture (29) in the brake shoe (1). A spring (9) also mounted on the brake shoe (1) is arranged to grip the latch member (5) and to hold the latch member (5) in the said operative position when this position is attained. The latch member (5) can be moved by a simple tool against the grip of the spring (9) to facilitate pad replacement.

Abstract: In a data processing system employing microcode techniques, complex sequences of microinstructions can be initiated by application of a single macroinstruction. These complex sequences of microinstructions are typically noninterruptible and therefore the execution of a macroinstruction is atomic (i.e., executed as a single entity). Data processing systems that do not employ microcode typically have simpler macroinstruction sets that do not provide for a similar atomicity for complex instruction sequences. In order to obtain the same atomicity of instruction execution and to provide a nonmicrocoded data processing system with the capability to execute complex instruction sequences as a atomic operation, the nonmicrocoded data processing system is provided with a third mode, in addition to the (nonprivileged) user mode and the (privileged) kernel mode, of operation that permits the execution of instruction sequences with interrupting events disabled and certain functions and apparatus enabled to facilitate instruction sequence execution.
