Title: Master cylinder with incorporated proportioning valve
Inventor: GAISER ROBERT FRANK
IPC: B60T11/20
Filed: 1980-10-01
Abstract: A master cylinder of the kind comprising two aligned pistons defining a primary and a secondary pressure chambers in fluid communication with respective brake circuits, and a proportioning valve carried by one of said pistons for reducing the pressure signal transmitted to an associated brake circuit upon a brake application. 
     According to this invention, the secondary piston (30) is hollow and defines with a fixed reaction piston a variable volume auxiliary chamber normally in fluid communication with the reservoir (24), and the proportioning valve is responsive to the fluid pressure within the primary chamber (32) for closing said fluid communication and thus increasing pressure within said auxiliary chamber to oppose further movement of the secondary piston upon a brake application. For use in automotive braking systems.

Abstract: A shared time-of-day (TOD) clock modification bit is used in a multiprocessing system in which the facilities in two or more CPUs are implemented as a function of a single TOD clock. This bit helps avoid timer errors that occur as the result of one central processing unit (CPU) changing the TOD clock value while another CPU is executing an instruction which determines a CPU timer value. Whenever the microcode in any one of the CPUs reads the TOD clock it obtains the Shared TOD Clock Modification Bit in addition to the TOD value. This bit indicates if the TOD clock read operation just completed is the first such operation executed by that CPU since the TOD clock was updated by another CPU sharing the same TOD clock. If it is, certain instructions take action to correct timer errors introduced by the change in the TOD dock value.
