Patent GB-2096371-A (GB)
Title: Debugging data processing systems
IPC: G06F11/28
Filed: 1982-04-02
Abstract: The invention relates to an apparatus for assisting fault-finding in a data processing system (10) having a target CPU (11) and a program under test. A record keeper (16) records input data and interrupts and a timing counter (21) measures time of interrupt or data input by counting instruction fetch events. The recorded information and each respective count is stored in a backing store (22). This produces a permanent record of external stimuli applied to the CPU (11) during program execution. Execution is replayed by a replay controller arranged to re-run the program under test in combination with the recorded external stimuli applied at appropriate occurrence times. Replay may be carried out using a host computer incorporating a CPU simulator program. <IMAGE>

Title: Propulsion unit for a water- borne vessel
IPC: B63H20/18
Filed: 1982-05-19
Abstract: In order to offer the advantages of an inboard motor with the improved steering of an outboard motor, a propulsion unit for a water-borne vessel has a propeller housing 10 at the lower end of a depending leg 9, and which can be rotated about the axis of the leg 9 for steering the vessel. There are two input coaxial shafts, namely a horizontal drive shaft 31 and a steering shaft 20 for rotating the propeller housing 10 about the axis of the leg 9. This avoids external steering controls extending to the leg 9. The leg 9 can be swung up about pivot pins 12, automatically disengaging the drive and the steering due to the incorporation of dog clutch members 37, 24. After swinging up, the leg 9 can be lifted off completely by withdrawing the pins 12 from their inclined slots 13. <IMAGE>

Patent GB-2111405-A (GB)
Title: A maskless process for applying a patterned solder mask coating
Inventor: FEFFERMAN GERALD BURT
IPC: H05K3/40
Filed: 1982-12-08
Abstract: A maskless process is disclosed for applying a patterned solder mask coating to a circuit board (31). In accordance with the process, there is applied to the surface (30) of the circuit board an uncured material (32) having a cure reaction which is susceptible to inhibition by the presence of oxygen. The surface of the circuit board is covered with the material to a first predetermined thickness. This first predetermined thickness of material on land areas (34) surrounding holes (36) in the circuit board is diminished to a second predetermined thickness by allowing a portion of the material on the land areas to flow into the holes. The uncured material is exposed to an energy source which delivers a quantity of energy such that a surface layer (38) having the second predetermined thickness has its cure reaction substantially inhibited due to the presence of oxygen. Any uncured material in regions having the first predetermined thickness undergoes an advancement in cure reaction in a sublayer (37) beneath the cure- inhibited surface layer. Thereafter the cure-inhibiting surface layer is removed from the circuit board with an appropriate solvent. <IMAGE>

Title: Central refuge island formcage with detachable backplate
Inventor: RICHARDS STEPHEN JOHN
IPC: E01F1/00
Filed: 1983-04-27
Abstract: The formcage consists of two sections which are (1) the shaped cage and (2) the backplate. The formcage is formed by bolting the backplate to the shaped cage and then securing to the roadbase using ragbolts through the fitted flanges. The cage is then infilled with concrete to form the central refuge island and remains as permanent formwork. Illuminated bollards or traffic signals are fitted onto the island and are fed by electricity cables through ductwork previously laid beneath the island. The backplate of the cage is then removable at any future date to enable access to the ducts by excavation without demolishing the whole island. The island can also be formed around existing traffic signals again enabling future access to supplying ducts. <IMAGE>
