Abstract: 1299380 Rotary positive-displacement machines TRW Inc 23 Dec 1969 [14 July 1969] 62668/69 Heading F1F In an hydraulic pump, or motor, a gerotor mechanism 27 has a ring gear 29a with tubular teeth 38 engaging with a gear 33 fixed to a rotary shaft 20, planetary motion of the ring gear being controlled by gear teeth 39, 40 thereon and on a housing member 13. To control the flow of working fluid between inlet and outlet openings 43, 44 and pockets 41a to 41g in said mechanism an annular plate 29b is secured to the ring gear by rivets 47, apertures 54a to 54g in the plate being connected to ports 57a to 57g by passageways 56a to 56g in the ring gear. Planetary motion  of the plate with the ring gear brings the apertures sequentially and alternately into register with annular grooves 43b, 44b, which are formed in a housing portion 12 and connected to the openings 43, 44. In a second embodiment, Fig.5 (not shown), a further pair of inlet and outlet openings is provided in a housing end-cap and another plate is secured to the other side of the ring gear to control the flow to and from these openings. A third embodiment, Figs.6 to 10 (not shown), has a single pair of inlet and outlet openings, a plate similar to the plate 29b fixed to each side of the ring gear, passageways corresponding to the passageways 56a to 56g formed in a plate lodged between the first-mentioned plate and the ring gear, and a pair of annular grooves on each side of the ring gear corresponding to the grooves 43b, 44b and connected to said openings, the two pairs of grooves being inter-connected by way of the gap between ring gear and the housing and passages in the shaft, respectively. A fourth embodiment, Fig.11 (not shown), is substantially the same as that shown but adapted to drive a road wheel of a vehicle. A fifth embodiment, Fig.12 (not shown), differs from the fourth one chiefly in that the shaft is fixed and the housing rotates.

Patent GB-2016247-A (GB)
Title: Improved method of signalling supervisory information in digital line transmission systems
IPC: H04L25/49
Filed: 1979-02-21
Abstract: In a line transmission system supervisory information is required in addition to digital information. Normally a separate transmission channel is required to transmit this information. The coding system of this proposal removes the requirement for an additional signalling channel. The method used requires that the line transmission coding employed should have more combinations than the coding of the data to be used (i.e. (2N-1) B->2NB). For example in optical fibre transmission systems it is usual to use line codes such as 3B 4B. In such a coding system there are 14 zero or 1 bit disparity codes which are available for mapping onto the eight "tri-bit" combinations of the data to be transmitted. Accordingly four illegal (i.e. unused) code combinations exist. Selective use of a pair of these illegal codes for the same pair of tri-bit combinations can be used to send a one bit supervisory signal.

Title: Timing method and device
IPC: G01M15/06
Filed: 1979-02-28
Abstract: The invention relates to apparatus for and a method of dynamically timing an apparatus such as an internal combustion engine which method includes cyclically generating reference pulses (K), and at least first and second timing pulses (L, M) the time between which is to be measured. The number of pulses of the reference signal in a generating cycle is counted and the time between a leading edge (N) of the first timing pulse (L) and a leading edge (P) of the preceding reference pulse (Q), measured. This time is divided by the period of the reference pulse to produce a first timing fraction. The time between a leading edge (R) of the second timing pulse (M) and a leading edge (S) of the preceding reference pulse (T) is measured and this time divided by the period of the reference pulse to produce a second timing fraction. The number of whole reference pulses (K) between the leading edges (N, R respectively) of the first and second timing pulses is counted, the first timing fraction subtracted from the count and the second timing fraction added to the count thereby producing a timing measurement between the first and second timing pulses (L, M) in terms of reference signal pulses (K). <IMAGE>
