Title: Heat exchanger with reciprocating surface - moved back and forth and rotationally using cranks to reduce solid deposits
IPC: F28F19/00
Filed: 1977-05-04
Abstract: The heat exchanger consists of three concentric tubes built together in such a manner that the space between the outer wall of the inner tube and the inner wall of the middle tube forms the flow passage for the liq. prod. and the central and outer spaces form the passage for the heat transfer medium. The central tube is so arranged that it can move backwards and forwards in an axial direction relative to the inner and outer tubes. This tube is either of prismatic cross-section, its movement then being purely linear, or circular in which case the tube reciprocates linearly and with a rotational movement relative to the two fixed tubes. The middle tube is driven by means of cranks which impart an irregular linear and rotational movement. The development of preferential flow paths and consequent stagnant zones in which solid deposits accumulate is avoided, and less cleaning is required.

Title: Fuel economy linkage for motor vehicle - may be selected by lateral movement of gear lever to reduce piston pressure
IPC: G05G13/00
Filed: 1980-02-14
Abstract: The modified gear selector is of the type in which the gears are selected by a front-to-rear movement of the lower (5). The accelerator pedal is connected to the fuel control system (35) via a pneumatic cylinder (42). The outer casing of the cylinder is connected to the pedal while the piston (43) is conne connected to the fuel control system (35). If the lever (5) is in the central position laterally, the pressure control unit (29) supplies equal pressures at the front (46) and rear (43) of the piston. For greater engine power, the lever is moved to the right, and the pressure at the rear of the piston is reduced, thus pulling the fuel control linkage (44) and increasing the effect of the accelerator. For fuel economy, the lever is moved to the left, reducing the pressure at the front of the piston, thus reducing the effect of the accelerator pedal.

Title: Frog and clog clock souvenir of Holland - has clock face set between two decorated clogs and frogs head emerging with croaking noise to mark the hours
IPC: G04B25/06
Filed: 1985-01-21
Abstract: This variant of the Alpine cuckoo clock is driven by tensioned spring clockwork regulated by a pendulum. The square clock face is supported on either side by wooden clogs decorated with Dutch symbols, e.g. tulips and figures in national costume.

Patent NL-8901282-A (NL)
IPC: G06F9/44
Filed: 1989-05-23
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.
