Abstract: The watchcase essentially comprises a crystal 1, or other transparent part visible from the outside of the case, assembled to the body 2 or a bezel exclusively by way of a layer 3 of low-temperature solder, in the nature of a silver or tin solder. A layer of barrier coating 5, chromium for example, serves to avoid diffusion of solder in the liquid state to the surface of the crystal. The zone of junction may be masked by a metallic coating 4, and the grip of the solder may be improved with a supplementary junction layer 6. It is thus possible to make watchcases of distinguished appearance, comprising junction areas of narrower width than those required when cement is used for the assembly.

Abstract: Sound attenuators used in ventilation, and in particular, for positioning adjacent ventilation fans that produce noise and vibration in such industrial areas as mines or factories. Known sound attenuators for such purposes are normally constructed of bulky and heavy material such as perforated metal and solid metal thereby tending to be easily dented and damaged and susceptible to corrosion. These attenuators also use sound absorbing material that if wetted renders the attenuator substantially useless wherein the attenuator must be replaced. Considering such problems as noted, a sound attenuator is provided suitable for use in reducing noise produced by axial flow fans used in industrial environs such as mines and factories. The sound attenuator comprising concentric inner and outer tubular members (10, 12) having sound absorbing material (14) positioned therebetween.

Abstract: A pulse floor selector for a lift, with a floor and location determining system based on counting pulses indicating the lift's velocity, with the aid of electronics thereto appropriate. Dense pulse floor selection is used for determining the lift's location, in particular in modern high speed lifts. To serve as pulse former, generally a pulse transmitter (PA) mechanically coupled with the motor is required, which supplies a number of pulses (PT) proportional to the distance traversed. The present invention represents a different approach wherein the requisite pulses are formed without transmitter. In the means of the invention, there has been connected to the tachometer generator (TG) giving the velocity of the lift, an analog/digital converter (A/D) which delivers to the electronics taking care of floor and location determination, a pulse train (PT) of which the frequency is proportional to the lift's velocity, whereby the total number of pulses per time unit is thus proportional to the distance travelled. In this manner, the pulse transmitter system (PP, PT) can be simply replaced by an IC circuit (A/D).
