Patent DE-2648938-A1 (DE)
Inventor: WIENENGA PAUL DIPL ING
IPC: H02P7/281
Filed: 1976-10-28
Abstract: Control and brake circuit for an electrical tractive unit fed from a direct current source, in which vehicle regenerative braking is carried out given power absorption capacity of the supplying power system during braking whilst in the absence of power absorption capacity the power system electric resistance braking takes place on brake resistors which are carried in the tractive unit. The connection of the brake resistor is effected by means of a thyristor (2.2) which is also active in travel mode. The firing time of the firing pulse for this thyristor must be dependent on the timing of the firing point of the ring-around thyristor of the DC chopper controller (5). As a result a relatively large control expenditure is produced. This expenditure is reduced by connecting the terminals of a DC-to-DC converter (9) to anode and cathode, the output of the DC-to-DC converter (9) influencing the control device (10) for the gate of the thyristor (2.2). By means of this device, the firing time of this thyrsitor can be fixed without errors, incorrect switching being avoided although the expenditure required on active and passive components is relatively low. <IMAGE>

Title: Film feed block and shutter cocking control - has cam preventing blocking while wind-on slider operates
Inventor: HAERTWICH GERT ING GRAD
IPC: G03B1/08
Filed: 1977-01-19
Abstract: The camera has a film feed block which operates when one frame has been indexed, and a claw has dropped into the single sprocket hole per frame. The slider also cocks the shutter and incorporates a blocking cam which prevents the film feed linkage from dropping into place until the slider has returned after setting the shutter. The slider has a cam which slides under the film feed blocking linkage and prevents it from operating. The system ensures that if the film drags the claws, through friction, rather than by a sprocket hole, the feed is not blocked and further operation on the slider is prevented.

Inventor: BIANCHESSI FRANCO
IPC: B29C49/58
Filed: 1977-06-28
Abstract: In order to obtain an optimum cooling effect on the inflated container (8), a specific amount of the gas or gases introduced into the finished shape (6) is directed constantly through the inflation nozzle (5) into the surroundings. The low-temperature gas introduced is directed only in the gaseous state of aggregation into the finished shape (6). The constant gas stream flows through a cooling-gas evacuation channel into the inflation nozzle (5), which cooling-gas evacuation channel is connected to an adjustable evacuation valve (9) in order to regulate the flow of the constant gas stream. The evacuation valve (9) can be a component of the inflation nozzle (5). These measures lead to a considerable increase in production rate without impairing quality. <IMAGE>
