Patent GB-2253926-A (GB)
Title: Robot navigation apparatus
Inventor: MARSHALL GILLIAN FIONA
IPC: G05D1/02
Filed: 1992-03-03
Abstract: Robot navigation apparatus uses a resistive god having nodes, each representing an individual and discrete position within a navigable environment 1, and internodal connections, all represented on a logic chip. Open circuit internodal connection(s) result in failure of the robot 3 to move further along the navigable path, and can lead to collision with obstacles 5, 6, 7 within the navigable environment. Detection of open circuit internodal connection(s) and prevention of movement of the robot along a path represented by the open circuit internodal connection(s) can eliminate problems associated with navigation along open circuit internodal connection paths. Selection criteria for robot movement direction include lowest node voltage, highest node voltage and calculated current magnitude comparison. Typical resistive grid topologies include hexagonal and rectilinear. <IMAGE>

Patent GB-925028-A (GB)
Abstract: 925,028. Autographic cash-registers. FRANK STEVENSON & SON (MANCHESTER) Ltd. Sept. 5, 1961 [Sept. 8, 1960], No. 30961/60. Class 16. An autographic cash register wherein a record web 15 and duplicate web 12 are fed by spring-pressed rolls 49, 50, engaging the duplicate web only, on operation of a lever 47, is characterized in that movement of the lever in a clockwise direction, as shown in Fig. 1, feeds the webs by a single line spacing, while movement of the lever in an anticlockwise direction feeds the webs by a multiple line spacing. The webs pass between spring - pressed rolls 22, 24, over a platen 8 having a transverse ridge 9 and beneath a transparent plate 5 having windows 6, 7, the record web passing out of the register through the window 7. A plate 27 mounted on a shaft 26 and rotated by the lever 47, is connected to a pawl cage 38 by rods 44, 46, slidable in slots 33, 34 in the plate. The pawl cage contains a ratchet-wheel 36 secured to a shaft 35 which also carries a pinion 37 mating with a pinion 47 secured to the spindle 48 of the feed roll 49. Movement of the lever in a clockwise direction rotates the pawl cage (and hence the ratchetwheel 36) in a clockwise direction through the agency of the rod 44, until the lower end of the rod 46 strikes the lower end of the slot 34. The pawl cage and lever are returned to their initial positions by a spring 42 on releasing the lever. Movement of the lever in the reverse direction again rotates the pawl cage and ratchet-wheel in a clockwise direction, this time through the agency of the rod 46, until the lower end of the rod 44 strikes the lower end of the slot 33. This latter movement brings an arm 28 on the plate 27 into contact with a plunger 29, which is depressed to release a latch 66, 67, whereby the cash drawer is projected by a spring 69. A plate 16 divides the register into a front compartment, containing the paper rolls 12, 15 mounted between slotted side plates 1, and a rear compartment to receive the duplicate web. The record web is provided with a coating of leuco dyestuff on its reverse side, as described in Specification 759,800, and the duplicate web is provided with a coating of clay on its obverse side, as described in Specification 659,036. The duplicate web may be rewound on a take-up spool carried on a further spindle, the latter being driven from the spindle 48 by a driving band passing around pulleys on the ends of the two spindles.

Feb. 19, 1962 [March 3, 1961], No. 7790/61. Heading G6C. A concrete pressure vessel 1 surrounds the core 2 of a nuclear reactor, and a layer 5 of heat conducting material lines the inner wall of the vessel and each penetration of the vessel, and pipes 6 containing a circulating cooling fluid are associated with the layer 5. These pipes 6 are preferably attached to the layer 5 by welding, but they may be located inside the layer itself (Fig. 3, not shown). Inlet and outlet ducts 3 and 4 enable a fluid to cool the core, and cooling ducts are arranged helically around the inlet and outlet ducts. A further layer 8 having thermal insulating properties is placed on the heat conducting layer 5 to prevent heat flow from the reactor and also to reduce the flow of neutrons to the concrete vessel. A heat resisting concrete may be used for this purpose. This layer 8 is made of neutron absorbing material. The cooling ducts 6, which may contain water are preferably arranged in parallel in single passes through the vessel so that should a stoppage occur in any duct the area where a hot spot can occur is less than in a multi-pass system. Further reduction in hotspots occuring is obtained by having a duplicate system of ducts.

Title: A braking force control system for a vehicle
Inventor: HIWATASHI YUTAKA
IPC: B60T8/1763
Filed: 1996-08-01
Abstract: In a braking force control system for a vehicle, a first target braking force 20 is derived not from the actual yaw rate but from the steering wheel angle via a section 16 for calculating an estimated yaw rate for a low friction surface and a section 14 for calculating a target yaw rate 14. A second target braking force is derived at section 22 from the steering angle, a target yaw rate gain, the deviation between actual and target yaw rate, the actual yaw rate, and the vehicle speed. When section 25 judges that the deviation of the actual and target yaw rates is in a control zone, section 26 outputs a signal to a brake drive apparatus 1 so as to apply the final target braking force at section 23 to a wheel selected in section 24, whereby the vehicle can make a smooth and stable turn without causing spins or drift-outs.
