Title: An anti-theft device for motor vehicles
Inventor: MAWDSLEY MICHAEL J
IPC: B60R25/09
Filed: 1990-08-31
Abstract: An anti-theft device for a motor vehicle includes an elongate wheel lock bar slidably displaceable within a guide member, the guide member being fixedly securable to the floor board of a vehicle. When so secured and by providing suitable apertures in the floor board and fire wall of the vehicle, the wheel lock bar can be displaced between an inoperative position and an operative position in which the bar will inhibit the normal operation of a front wheel of the vehicle, thereby effectively immobilising the vehicle. An electric motor is provided for displacing the wheel lock bar via a displacement shaft, operation of the motor being controlled by a control means in a manner that displacement of the wheel lock bar into its operative position will occur automatically upon the vehicle engine being switched off and the vehicle door being opened, whereas displacement into its inoperative position will require transmission of a coded signal to the control means.

Patent CA-2029053-A1 (CA)
Inventor: BRUNNER BEAT
IPC: H04Q3/52
Filed: 1990-10-31
Abstract: A multi-stage, alternate routing switching network is enhanced with a switch architecture that is able to detect and mask all single faults.  The switch employs a controller that develops dual rail control signals.  In one embodiment, the controller is made up of two controllers that receive the same inputs but generate complementary outputs.  The complementary outputs form the dual rail signals that control the multiplexers that are interposed between the inputs and the outputs of the switch.  The dual rail control of the signal routing within the switch allow foreffective detection of all single faults in the signal routing means.  Inclusion of totally self checking circuits at the switch outputs as well as inputs enables users to readily isolate a fault and identify its source.

IPC: C23C4/067
Filed: 1991-04-08
Abstract: In a process for coating the blades of a rotating, thermal machine, said blades undergo a first cleaning process in the operating state of the machine, i.e. "on line", the appropriate agent fox this, which depends on whether the blades are uncoated or coated, being mixed in with the air stream to the compressor.      After switching off the machine and opening the same, the blades undergo in the stationary state, that is to say in the bladed state of the corresponding rotor or stator, a preparation process for the subsequent treatment stage. According to requirements, this preparation process may, for example, consist in the blades being immersed in a vibrating erosive bath. The actual coating of the blades takes place by means of a high-speed flame spraying process, in which the protective coating is sprayed onto the surface of the base material at a particle velocity of at least 300 m/s. Thereafter, the blades also undergo an after-treatment which, according to requirements, serves to reduce the surface roughness and/or is provided to apply a top coating.
