Patent CA-2106751-A1 (CA)
Title: Device in a brake unit
Inventor: SEVERINSSON LARS
IPC: F16D65/28
Filed: 1992-03-31
Abstract: An electromechanical brake unit in a housing (1) is provided with a drive sleeve (8) subjected to a torque of a prestressed coil spring (6), a locking spring (16) between the drive sleeve and the housing for permitting rotation of the former in a first direction, and a control sleeve (17), which is rotatable by a control motor (20) in the first direction to open the locking spring and allow the drive sleeve to rotate the same angular distance as the control sleeve. In order to obtain rotary force transmission from the drive sleeve (8) over the locking spring (16), if the control sleeve (17) is not held against rotation, the locking spring has a slightly smaller external rest diameter than the bore in the housing (1), with which it is to cooperate, whereas the control motor (20) is provided with means to hold it against rotation in its rest position, unless the current supply is broken.

Title: Digital dimming and flashing circuit for locomotive ditch lights
Inventor: WETZEL DONALD C
IPC: B60Q1/54
Filed: 1994-06-14
Abstract: DIGITAL DIMMING AND FLASHING CIRCUIT                 FOR LOCOMOTIVE DITCH LIGHTS     ABSTRACT OF THE DISCLOSURE      A light is dimmed by pulsing it at a selected duty cycle. By pulsing, the light can be dimmed without being turned off completely which reduces wear on the filament.  The circuit is designed for flashing a pair of ditch lights on a railroad locomotive.  The lights are alternately illuminated at full voltage and dimmed by pulsing.  The flashing sequence can be activated when the locomotive is travelling below a selected speed or when the horn is sounded.   The duration of the flashing sequence is controlled by a timer.   The pulsing circuit can be used to effectively reduce a voltage without voltage dropping resistors.

Patent CA-2145169-A1 (CA)
Inventor: BERRENS LUBERTUS
IPC: A61P37/08
Filed: 1992-09-21
Abstract: The invention concerns the removal of various allergologically irrelevant low-molecular weight components from the usual aqueous extracts of allergenically active proteins of plant pollens. Described are the desorption and subsequent elimination, from traditionally prepared allergenic pollen protein extracts, of low-molecular weight pigment and other compounds which are nor-mally retained by strong electrostatic and/or hydrophobic forces. The preparation of such depigmented pollen proteins does not impair their allergenic potency or immunological specificity. The invention enables the production of fully active allergenic poll-en proteins devoid of adhering low-molecular weight substances interfering with their safety, diagnostic accuracy and clinical ef-ficacy. The purified pollen proteins represent improved starting materials for chemical derivatization, i.e., the preparation of at-tenuated vaccines for immunotherapy. The invention also provides suitable products for investigating the molecular structure of allergenic epitopes.
