Title: Use of location-determining systems
IPC: B60P3/03
Filed: 1989-03-09
Abstract: A security system uses a navigation system, which may be radio-based, dead-reckoning or a combination of the two, to monitor the location of a vehicle or container so as to signal that it has deviated from a predetermined route and/or to control operation of a physical locking or unlocking device so as, for example, to enable a container or compartment only to be opened at a predetermined location. Thus the invention is applicable inter alia to cash-in-transit systems, to prevent secure compartments being opened except at prescribed drop-point and also to floating vessels to restrict locations at which they can discharge material.

Title: Application of bearing alloys to bushes
IPC: F16C33/12
Filed: 1989-03-22
Abstract: Bearing alloy is applied to a bush (10) by mounting 
the bush (10) on a support structure (14) having an 
upstanding mandrel (17) so as to form an annular 
interspace (20) for reception of the bearing alloy in 
liquid form. The mandrel (17) projects above the bush 
(10) and has certain predetermined minimum dimensions. 
Infrared heating is applied to the bush (10) and the 
mandrel (17) sufficient to prevent the liquid bearing 
alloy freezing on contact with any of the surfaces 
defining the interspace (20). After degassing the liquid 
alloy is controllably cooled by coolant applied to the 
exterior of the bush (10) and finally the metalled bush 
is freed from the support structure (14).

Title: Cylinder head structure for plural cylinder engines
IPC: F01L1/26
Filed: 1989-08-01
Abstract: A cylinder head structure for a plural 
cylinder engine, comprising, at least for each of 
its cylinders located at either longitudinal end of 
its cylinder bank: a combustion chamber (13) defined 
by the cylinder and a piston received therein; an intake 
passage (18) communicated with an intake manifold (20) 
at its one end and with said combustion chamber (13) 
at its other end; an exhaust passage (19) communicated 
with an exhaust manifold (21) at its one end and with said 
combustion chamber (13) at its other end; at least one of 
said intake passage and said exhaust passage being curved 
toward a longitudinally central part of said cylinder bank as it 
extends from its other end to its one end. Hence, the 
size and weight of the intake manifold and/or the 
exhaust manifold can be reduced. In particular, if the 
passage is communicated with the combustion chamber by 
a pair of ports controlled by valves and arranged along 
a longitudinal direction of the cylinder bank and 
different flow rates are assigned to these ports 
depending the operating conditions of the engine, a 
significant improvement in the performance of the 
engine may be attained by symmetrically arranging these 
ports with respect to a longitudinal center of the 
cylinder bank.
Patent EP-0354771-A3 (EP)
Title: Personal identification number processing using control vectors
IPC: G07F7/10
Filed: 1989-08-09
Abstract: Cryptographic PIN processing is achieved in an improved manner by 
associating control vectors with the PIN generating (verification) keys 
and PIN encrypting keys which provide authorisation for the uses of the 
keys intended by the originator of the keys. The originator may be the 
local cryptograhic facility (CF) and a utility program under the control 
of a security administrator, or the originator may be another network 
node which uses compatible key management methods to distribute the 
keys. Among the uses specified by the control vector are limitations on 
the authority to use the associated key with certain PIN processing 
instructions, such as PIN generation, verification, translation and PIN 
block creation. Furthermore, the control vector may limit the authority 
of certain instructions to process clear PIN inputs (such as in PIN 
verification). The control vector may contain information identifying 
and, possibly restricting, PIN processing to a particular PIN format or 
particular processing algorithm.

Title: Inertia damper
IPC: F16F15/12
Filed: 1990-03-14
Abstract: An inertia damper (20) capable of exhibiting 
satisfactory endurance. In the inertia damper, when an
