Title: Device for winding a seat belt in vehicles
IPC: B60R22/46
Filed: 1975-04-16
Abstract: A device for winding up a vehicle seat belt in the event of a vehicle impact comprises a hollow winding drum rotatably mounted in a casing coaxially surrounding a threaded central axle which is rotationally fast with the casing. An annular piston inserted between the drum and axle is axially movable by the pressure generated by combustion gases issuing from a pyrotechnic charge detonated by a signal from an impact detector, to rotate the drum and wind up the belt, the piston being keyed for rotation with the drum and for helical movement relative to the axle. Under normal conditions the drum is free to rotate to wind up and unwind the belt, but a mechanism is automatically actuated upon impact to prevent or oppose rotation of the drum in an unwinding direction.

Abstract: Prepn. of d-2-(6-methoxynapth-2-yl)propionic acid comprises (a) condensation of the corresp. racemic propanal with d-oxalic acid alpha-phenylethylamide hydrazide in anhydrous benzene in presence of iodine (b) resolving the diastereoisomeric hydrazones by crystallizing from dioxan to give the pure d-d isomer (c) hydrolysing the d.-d-isomer with 20% H2SO4 to give the d-propanal and (d) oxidising the d-propanal with sodium hypochlorite soln. in presence of sulphamic acid. The l-I isomer may be recovered tom l-d-III in the fioxan mother liquors, racemized and treated as above. Simple process, economic because the l-isomer of the propanal can easily be racemized to give the d-acid. Product is an antiinflammatory, analgesic, antipyretic agent. Typically, pure d-d-III hydrazone, crystallised from dioxan, was hydrolysed with 20% H2SO4 at reflux for 15 min to give almost 100% yield of d-propanal. Oxidation with Na-OCl in water and benzene in presence of sulphamic acid gave 75% of d-2-(6-methoxynaphth-2-yl)propionic acid.

Title: Automatic gauge control method and apparatus for tandem strip mills
IPC: B21B37/16
Filed: 1978-08-04
Abstract: A method and apparatus for automatically controlling the gauge of metal strip rolled in a tandem strip mill. Load cells installed on a first stand generate signals representative of changes in the roll-separating force, and hence of gap error, at this stand. Such signals are fed-forward, with a delay to allow for transport time of the strip minus screw-reaction time, to a second stand to effect screw adjustment of the latter. Signals representative of gap error at the second stand, corrected for changes in the position of the screws at the second stand, are fed-forward to effect screw adjustment at a third stand, etc. The screws of the first stand are maintained at their original setting, while adjustments in the screws of succeeding stands made in response to changes in the roll-separating force are effected exclusively by signals fed-forward from a preceding stand.

Title: Electron gun cathode support
IPC: H01J9/04
Filed: 1979-07-18
Abstract: An electron gun for a camera tube includes an anode and a cathode. The cathode is assembled in a cathode support which can very readily be adjusted relative to the anode in the nonconnected condition. In particular, the cathode support and the anode are movable radially with respect to each other and with respect to an axis. An emissive cathode surface and a part of the anode extending perpendicular to the axis remain accurately parallel to each other during the radial movement. As a result of this it is possible to cause the central path of the generated electron beam and the gun axis to coincide so that extra correction coils for aligning the electron beam may be omitted.
Patent ES-485320-A1 (ES)
Title: A driving system for driving a machine element in a repeated reciprocating movement along a linear path.
IPC: F16F9/48
Filed: 1979-10-24
Abstract: When a machine element having a large mass is given a reciprocating movement, the recurring changes in speed as well as direction of movement require that very great driving forces must be applied, which cause varying stresses on the driving unit. In case the movement path of the machine element is more or less vertical the force of gravity causes extra stresses on the machine element. These difficulties are overcome in accordance with the invention by providing a spring system which on the one hand equalizes the effect of the force of gravity on the machine element and, on the other hand compensates the arising mass forces by absorbing, storing and emitting energy following the movement of the machine element. Hereby the amount of applied driving force is reduced, so that shocks and vibrations occurring during the driving are effectively reduced.

Title: Method for the manufacture of a pole shoe for electrical machines
IPC: H02K15/02
Filed: 1980-03-07
Abstract: The present specification discloses a method for the manufacture of a pole shoe for electrical machines by the non-cutting shaping of a rolled- section blank. In known non-cutting methods the blank is fully subjected, during each shaping stage, to the forming forces simultaneously both in the region of the pole shoe core and in the region of the pole horns. The method of the present invention is performed by means of a progressive tool (1, 2,) (8, Figure 1, not shown) in two shaping stages, or in a device comprising two upsetting dies (24, 26). In the first shaping stage the core region (12) of the pole shoe is fully formed, and, in the second shaping stage, the pole horns (18, Figures 3,6, not shown) are fully formed by pressing. According to this method the forming of the core region (12) and the forming of the pole horns (18) are performed by separate applications of force, whereby the forming forces may be substantially reduced.
