Patent DE-2343674-A1 (DE)
Title: Press brake for sheet metal work - with sheet support table pivoted by compressed-air cylinder
Inventor: PAETZOLD HANS
IPC: B21D5/02
Filed: 1973-08-30
Abstract: A bending press has a vertical punch, and a table is mounted on a compressed-air cylinder so that, at rest, the table surface is level with the die and by operating the cylinder the table can be swung upwards in an arc. The press, in the cylinder is adjusted so that it is just below the force required to lift the combined wt. of the table and the sheet being bent. As soon as the sheet lifts during the operation of the punch, the press. in the cylinder swings the table so it follows the sheet, damping out the vibration which occurs on bending and supporting the sheet at all times. The advantages are better dimensional accuracy, reduced distortion of the sheet, and less noise as the sheet does not drop back i.e. on to fixed table.
Patent DE-2344850-A1 (DE)
Title: Pressure and flow activated control for pump - has pressure switch and hot wire flow meter
Inventor: BACH BERNHARD
IPC: F04B49/10
Filed: 1973-09-06
Abstract: The pump supplies a system with a small pressure tank. A pressure switch works a relay and a hot wire flow meter with heater works a relay in the pump motor circuit. As the pressure falls after the pump has stopped the pressure switch closes and completes the circuit to the flow meter heater. As the flow meter is still cold it closes relay which starts the pump and holds the flow meter heater in circuit independently of the pressure switch so that the motor stays on even when the pressure switch opens again. The pump stops only when the flow drops and the hot wire flow meter opens the relay.

The surface treatment process may consist of immersing the metal or using a spraying method, and the ozone employed can be obtd. either from oxygen or from the air. The ozone provides a continuous supply of active, atomic oxygen which accelerates the picking or etching process.

Title: Emergency replacement vehicle fan belt - uses lever strap or elastic section avoid need for use of tools
Inventor: HILLESHEIM HANS
IPC: F16G5/00
Filed: 1974-04-25
Abstract: The belt is particularly for use as an emergency replacement by vehicle drivers on the fan and dynamo drive, etc. and is fitted and removed without any tools being necessary. This can be effected by altering its diameter, using elastic intermediate components, and the elasticity can be such as to avoid the need for loosening any of the mounting screws of the individual engine auxiliaries. In addition to the elastic components there can be further metal and/or plastic components, having no contact with pulleys when running, allowing temporary increase of the diameter, reducing again to the original diameter after fitting.

Title: Asymmetric self righting lifeboat - with totally enclosed fireproof deck and asymmetric profile for uneven buoyancy
Inventor: HATECKE HELMUT
IPC: B63C9/03
Filed: 1974-10-31
Abstract: The lifeboat is fitted with an asymmetric profiled deck (27) to give more buoyancy on one side when capsised. This provides a rapid self righting force to keep the boat upright even in the roughest seas. To aid the self righting action the bottom of the boat has ballast displaced to one side, with the amount of ballast required for stability less than would be required for a symmetrically profiled craft. The deck completely covers the boat and special pumps, driven by the internal engine, provide water sprays over all the outer surface so that the boat can be safely moved through burning oil slicks.

Title: Slow speed turning gear employing a toothed wheel - makes use of single pawl driven by motor and engaging with the wheel
Inventor: REIMUND HANS
IPC: H02K7/07
Filed: 1974-11-12
Abstract: The application is to the low speed turning of rotor shafts to prevent bending, or to the slow turning over of compressors for inspection, or similar duties. The shaft is fitted with a toothed wheel of required diameter. A single latch or pawl driven by a motor, typically through a mechanical eccentric linkage, engages with the wheel to move it forward at least one tooth and then, as the motor continues to turn, is lifted clear of the wheel until it eventually returns to the position at which the next power stroke commences. The arrangement requires no great attention to alignment and meshing when setting up. By use of limit switches it can be arranged that the pawl is always clear of the wheel when the motor is stopped.
