Patent GB-2231538-A (GB)
Title: Pneumatic tire with directional tread
Inventor: USHIKUBO HISAO
IPC: B60C11/00
Filed: 1990-01-03
Abstract: A pneumatic tyre has directional aspects both as to the plan view of the tread pattern, and the cross section of transversal grooves. The tread is disposed at the crown of a toroidal casing and is formed of blocks partitioned by circumferential grooves, and by transversal grooves arranged in a regular herring-bone pattern. The apex of a herring-bone groove is typically placed at the circumferential centre line of the tread, and the direction of rotation is such that the apex meets the road ahead of the flanks of the herring-bone. The transversal grooves are of asymmetric cross-section such that the groove root radius at the groove edge which leads in the direction of rotation is smaller than the trailing groove root radius. The leading groove wall angle may be less than the trailing wall angle. -

Title: A rest for supporting a fishing rod
Inventor: JOHNSON JAMES L
IPC: A01K97/10
Filed: 1990-06-13
Abstract: The rest 10 comprises an elongate carriage bar 14 mounted upon a support leg 12 by a locking device 15.

Title: Auxiliary endless track mechanism for automobiles
Inventor: SOO-CHEOL JUNG
IPC: B60T1/14
Filed: 1990-10-03
Abstract: An automobile is provided with an auxiliary endless-track mechanism to enable it to run easily in adverse conditions, to stop very abruptly and to turn in a small space. The endless tracks (7), which may be of rubber with gripping projections, are mounted on a tubular frame which is extendable and retractable eg by hydraulic cylinder (120) towards and away from the ground. Drive to the tracks may be taken from the output shaft (14) of the main transmission (12) by means of bevel gears (17 etc.) and shafts which ultimately drive the track sprockets. The endless-track frame can be rotated about a vertical axis relative to the automobile by an electric motor for tight turns.

Title: Contra-rotating prop-fans
Inventor: ROHRA ALOIS
IPC: F02K3/072
Filed: 1990-12-19
Abstract: A prop fan engine comprises two oppositely rotating fan rotors 1, 2, which are both driven by means of a drive shaft 6 of a low-pressure turbine. The shaft 6 drives a planetary gear carrier 23 rotatably supporting planet gears 12a, 12b. The gear 12b meshes with a ring gear 13 secured to housing 9, while gear 12a meshes with a ring gear 14 drivingly connected to fan rotor 1. Fan rotor 2 is driven by the shaft 6 via carrier 23 and sleeve 17. This ensures an advantageous realisation of the speeds of the fan rotors and the turbine, and requires less space and weight for the two fan rotors compared with conventional gearing. In alternative arrangements, the shaft is connected to drive the front rotor directly, with the roar rotor being driven via gear 12a (Figure 2), or a third planetary gear (30) is provided on the same shaft 11 as the other planetary gears and meshes with a third ring gear (31) coupled to a booster compressor (27) (Figure 3). <IMAGE>

Title: Transistor module with special impedance terminal
Inventor: YAMADA TOSHIFUSA
IPC: H05K3/34
Filed: 1992-11-09
Abstract: An external lead terminal 5 of a transistor module, comprises an internal terminal portion 6 and an external terminal portion 8 which are conductively connected to each other via a U-shaped intermediate terminal portion 7 having a curved portion 7b. Connected in parallel with this intermediate terminal portion 7 is a shortcircuit wire 9 having a larger electric resistance and a smaller inductance than the same. For this reason, even if a current is reduced suddenly in a state in which the current is flowing from the external terminal portion 8 to the internal terminal portion 6 via the intermediate terminal portion 7, the current shifts to the shortcircuit wire 9 side, so that a transient voltage is low. Consequently, the transistor module is capable of reducing a transient voltage without being subjected to restrictions in the size of an external lead terminal while maintaining a high level of reliability. <IMAGE>

Title: Operation of an internal combustion engine
Inventor: MA THOMAS TSOI-HEI
IPC: F01N13/02
Filed: 1993-04-15
Abstract: A method is described for operating an engine having an afterburner 16 and a catalytic converter 11 downstream of the afterburner. Sufficient excess fuel is introduced into the engine to produce in the exhaust gases fuel constituents including unburnt hydrocarbons, carbon monoxide and hydrogen. Unburnt hydrocarbons are intercepted by absorption on brick 10 upstream of the afterburner 16 so as to allow substantially only carbon monoxide and hydrogen to reach the afterburner. Sufficient additional air is introduced into the exhaust system to bring the composition of only the carbon monoxide, hydrogen and air to stoichiometry or leaner than stoichiometry, the resulting concentration of hydrogen and oxygen in the mixture reaching the afterburner being sufficient for ignition immediately after a cold start. By removing the hydrocarbons temporarily before the exhaust gases reach the afterburner, reliable cold ignition can be achieved with lower levels of fuel enrichment. <IMAGE>
