Title: Oscillating settling tank raking device - with adjustable weights on shields pivoted to endless chains with ascending discharge
Inventor: ALTMEYER HANS J
IPC: B01D21/04
Filed: 1976-11-24
Abstract: A raking device for rectangular setting tanks in sewage engineering consists of endless chains which are guided by deflection sprockets and carries raking flights. The flights are pivoted to the chains so that they can oscillate. In the horizontal part of the tank guides of horizontal rails are provided for the chain. The solids which settle at the bottom of the trough in the settling channel are moved by raking shields which can oscillate on pivots of endless chains. Adjustable weights can be added to the side arms of the shields. In the horizontal section, the chains are rigidly guided in rails. This saves the construction of a travelling bridge and the design of a tank strong enough that its rim can stand the weight of the bridge. The flights can deflect during starting (thus reducing the motor starting torque) and when encountering any obstacle.

Title: Tennis racket with hollow frame - has granulated weights added to adjust balance of frame for individual user
IPC: A63B49/02
Filed: 1977-09-16
Abstract: A tennis racket has a frame which is formed by one or two hollow sections (9). The sections are divided into a number of individual chambers (13) which remain accessible. In order to balance the weight of the racket head to suit different players, granulated weights (30) are placed inside the chambers (13). Since the chambers (13) are not completely filled, the weights are able to move in the direction of the racket movement. This helps to increase the impact force on the tennis ball as the weights are thrown against the leading walls of the chambers. The weights also absorb vibrations of any amplitude and frequency, thus reducing player fatigue.
