Title: A dispenser for flowable material such as grease
Inventor: CLEMENTS COLIN
IPC: F16N13/16
Filed: 1982-01-19
Abstract: A dispenser for flowable material, such as grease, comprises a main body 10 including a discharge chamber 16 having an inlet 28 and an outlet 26, means 19 for discharging flowable material from the chamber through sad outlet 26, an enclosed reservoir 12 for the flowable material mounted on the main body 10 and communication with the discharge chamber through said inlet 28, a ventilation chamber 17, means 34 for supplying the ventilation chamber with air, and a ventilation duct 31 communicating between the ventilation chamber and the interior of the reservoir.

Title: Arrangement for coin-handling machines
IPC: G07D3/00
Filed: 1981-11-10
Abstract: Arrangement for coin-handling machines of the type which comprises an upper coin-sorting path (2) and a lower coin-sorting unit (7) arranged underneath the path.
