Title: Loader and trailer transporter for straw bales - has side elevator depositing bales into compartment cage which unloads through base
IPC: A01D90/08
Filed: 1976-02-19
Abstract: The trailer transporter is equipped with a side elevator for loading bales of straw. This operation is carried out automatically, the bales being deposited into a compartmented cage. This has arms spaced along its length and pivoting at the top, each arm lying at 20 deg. to the vertical. Drop-down flaps, pivoting on the bottom of the arms and closed when loading, release the bales downwards when the cage is progressively pulled off the trailer. The elevator catches the bales and spiked chains and passes them onto an overhead conveyor. A tipping flap guides these into the compartments, the elevator moving forwards.

Title: Dual circuit disc brake with double pistons - has self-adjusting piston to resist reaction when one circuit fails
IPC: F16D65/18
Filed: 1976-05-20
Abstract: The disc brake is provided with a stirrup (1) with two opposing cylinders (9) for pistons (11) and (12). The cylinders (9) are supplied with hydraulic fluid from independent circuits. In the event of a failure of one circuit, the active piston is pressed against the brake disc (2) and the force is re-acted by the inactive piston which is locked by its self-adjusting mechanism. One self-adjusting mechanism consists of a split cone (21) mounted on a shaft (24) screwed into the base of the cylinder (9). The split cone (21) allows the piston (11) to be forced onto the brake disc but limits its return travel. An alternative method uses a non-return valve (36) inside the piston (12) which allows hydraulic fluid to flow into the space (31) when the brake is applied but prevents its return when the brake is released.

Title: Mechanically cleaned bar screen - with brushes moved by endless chain along downstream side denetrating to upstream side
IPC: B01D29/00
Filed: 1977-03-14
Abstract: A bar grating to remove coarse floates and garbage from flowing water and sewage has cleaning elements (I) which can be mechanically moved longitudinally between the bars.

Title: Automatic pointing system for detector to moving radiator - uses two opposing fluid bellows onto which radiation energy is directed
IPC: F24S50/20
Filed: 1977-06-28
Abstract: The system uses a servomotor (3) which rotates the detector (1) around an axis (2) and an aiming element which rotates with the detector. The aiming element controls automatically the servomotor. The aiming system has two identically detecting elements (9a, 9b) which deform as a function of the amount of flux energy they receive from the source. The two elements are mounted in opposite directions. The system has a moving element on which the detecting elements act in opposition. The displacement of the moving element is thus a function of the difference in energy received by the detecting elements. A screen is placed between the source and the detector so that illumination of the two detecting elements is equal when the detector is aimed onto the source.

Title: Measurement of static or dynamic axial bearing thrust - using strain gauges at deformation region for increased accuracy and reduction of intermediate transfer elements
IPC: G01L5/00
Filed: 1977-09-01
Abstract: The measurer determines the static and/or dynamic axial thrust on a fixed bearing using strain gauges. It reduces the number of intermediate thrust transfer elements. Frictional forces are also reduced in order to avoid errors due to high temp. at high revolution rates. The part of the bearing which is stationary in operation has a thinner than usual section near its periphery which deforms under axial thrust and is used with strain gauges for thrust measurement. Compensation gauges are placed diametrically opposite the measurement gauges and connected with them in a bridge circuit.
