Abstract: A water meter has a measurement insert disposed in a meter housing, a measurement display, an intake connection and a discharge connection. An impeller is disposed on a shaft in a measurement insert housing, also referred to as impeller bowl. A first shaft end of the shaft interacts with the measurement display. The meter housing has, on a side facing away from the first shaft end, referred to as a lower side below, recesses or openings for receiving fasteners for fastening a cover, and a calibrating device for adjusting the measurement display. The calibrating device is inserted into at least one of the openings that can be closed by the cover.

Abstract: A water meter has a measurement insert disposed in a meter housing, a measurement display, an intake connection and a discharge connection. An impeller is disposed on a shaft in a measurement insert housing, and a first shaft end of the shaft interacts with the measurement display. A supporting part is disposed between the meter housing and the measurement insert housing. Because of the supporting part, forces, acting in the axial direction of a second shaft end of the shaft through the measurement insert housing, can be absorbed and the forces can be conducted into the meter housing.

Abstract: Disclosed herein is a scaffold system having a first deck structure having a first deck structure frame, a deck connected to the frame and including a deck hatch. The system also includes a second deck structure having a second deck structure frame and a deck connected to the frame, the second deck structure positioned at a distance from, and connectable to, the first deck structure. The system further includes a telescoping ladder positioned between the first and second deck structures and connectable to at least one of the first and the second deck structures, the telescoping ladder extendable to a length that corresponds to the distance between the first and the second deck structures. Also disclosed is a resilient deck hatch hinge. Advantageously, a user can ascend the scaffold system from one deck structure to the next while remaining inside the scaffold footprint, promoting safety. The telescoping ladder promotes greater efficiencies from the scaffold supply standpoint.

Abstract: An end cap system for scaffolding planks, especially for hollow core planks. The end cap includes an extrusion having a plank-receiving portion on one side and a rib profile on the other for slidingly receiving scaffolding hooks. The end cap permits similar parts to be used for a wide variety of plank widths and allows for replacement of damaged hooks or the exchange of hook configurations. In the most preferred embodiment, the hooks are fixed to the end cap, such as by a set screw, after they are slidingly located at the desired position. The end caps may be used with either "high" or "low" hooks.

Abstract: An attachment device for a scaffolding system which includes vertical and horizontal tubes is comprised of a guard rail stud adapter and a first stud. The guard rail stud adapter includes a generally U-shaped member which has a base portion, a first arm connected to the base portion, and a second arm connected to the base portion. At least one of the arms may include an end which has an arcuate cut-out portion for receiving vertical tubes. A second stud is connected to the generally U-shaped member for retaining scaffolding members, such guard rails or other members. A generally l-shaped member connected to the U-shaped member has a first end connected to at least one arm and a hole for receiving the first stud of the scaffolding system. One embodiment is further comprised of a spacer having a counter-bore for receiving the second stud of the scaffolding. Tile spacer is connected between the second stud and the generally U-shaped member.

The end caps of the present invention may be used with either "high" or "low" hooks.

Abstract: Disclosed is a bar-tumbler type safety lock, as well as a key and a coding process for said lock. According to a single-key-entry embodiment, this lock comprises a body, a two-piece washer, a latch holder and a barrel having recesses in which notched tumblers can slide and which is maintained rotatingly and removably toward the front of said body by a stud and a stopping finger retained in two annular slots made radially in this body and which can be retracted by the introduction of a special extraction key into the lock; the coding of the lock is obtained by the turning, in the annular washer-assembly groove, of notches made simultaneously in each of the tumblers with the key inserted.
