Title: Brake-lever adjusting device
Inventor: MORENO GONZALES MIGUEL
IPC: F16D65/60
Filed: 1988-03-18
Abstract: In a brake-lever adjusting device, the cams that drive the brake shoes are actuated by the brake lever via a spindle and worm wheel mechanism (5, 6). As the brake shoes wear, the angular position of rest of the cam (3) is readjusted via the spindle (5) of the mechanism, the spindle being driven by a double detent-pull mechanism arranged on the outside of the brake lever (2), on an axial extension of a shaft (7) of the spindle (5), this mechanism comprising a splined sleeve (4) surrounding the extension and a diametral hole passing through the extension, in which there slide two detent pulls preloaded against the splined internal surface of the splined sleeve. The splines have an uneven number of grooves so that, when one of the detent pulls engages in one of the grooves, the opposite detent pull lies between two successive grooves. A lug attached to the side of the splined sleeve (4) is connected to one end of a connecting rod (17), the other end of which is connected in such a way to a rear extension of the actuating rod (1) of the brake lever that the splined sleeve (4) is turned backwards and forwards with each braking stroke. <IMAGE>

Title: Boiler with atmospheric burner and optimised secondary-air supply
Inventor: HILLE FRITZ DR ING
IPC: F23D14/10
Filed: 1989-04-26
Abstract: The invention relates to a boiler with atmospheric burner and optimised secondary-air supply. Owing to the special arrangement and dimensioning of the slot-shaped openings underneath the burner tubes, a uniform supply of secondary air to the burner tubes is ensured. By further measures, such as angling of the longitudinal edges of the slot-shaped openings towards the burner tubes, and flow-directing bodies which are arranged approximately perpendicularly above the slot-shaped openings, a further improvement of the flame cooling by secondary air is achieved. Adjusting devices for regulating the distance between burner tubes and slot-shaped openings and also for adjusting the slot width enable improved adaptation of the secondary-air supply and thus flame cooling to the waste gas-conveying devices of individual installations, which may be very different.

Title: Hollow insulating zones - have absorption units to block condensation development which can be replaced and regenerated
Inventor: KLIESCH CHRISTOPH
IPC: E06B7/12
Filed: 1990-03-13
Abstract: The method to give durable inhibition to the development of condensation in the hollow zones between insulating glass panes, hollow wall facings, tubes and the like, has absorption units which can penetrate the gass filling of the hollow zones, from outside, held at dewpoint values below the service temp. The durable absorption effect is maintained by the exchange of used absorption media and/or their regeneration. The absorption unit pref. has pressure compensation with the ambient atmos. through an opening to the outer air or an elastic vessel between the absorption unit and the outer air which can be activated. The absorption unit is directly at the hollow zone to be protected or it extends into it, or is located separately with a tube and/or hose connection.  The absorption unit can be at or in the elastic vessel. The absorption unit is a replaceable unit, pref. a visible colour indicator or moisture measurement meter to indicate or control an exchange action. The absorption unit can be regenerated while in position, using heat to expel the moisture wholly or partially and any vapour to be passed to the outer atmosphere through a valve.  The heat energy to dry the absorption media can be taken from the electrical power supply, solar energy,  regenerated energy or combinations of energy sources. Where the hollow zones are in moving bodies, such as revolving doors, the linkages between the absorption units and the hollow zones are temporarily broken during movement and then reconnected. ADVANTAGE - The vapour pressure from the gas filling in the hollow zones is durably held so low that condensation cannot develop.  It also prevents the formation of pressure differences which could lead to distortion of  the sides containing the hollow zones.
