Abstract: Aluminum alkoxides are prepared by the reaction of impure aluminum and monohydric alcohols in a process wherein impure metallic aluminum particles (in 2, 4 and 8) are continuously fed at a metered rate into a stoichiometric excess of alcohol (in 10). The novel apparatus disclosed permits the continuous introduction of the aluminum particles into the reactor and removal of non-reactive impurities through columns of ambient temperature alcohol which avoids contact of atmospheric oxygen with the reaction products.

Abstract: In a clamping unit, particularly in a chuck with exchangeable jaws, one terminal clamping position is reached during opening when the clamping jaws approach the limit of stability. The other end position is reached during closing when the jaws approach the point where they cannot be moved any further. However, both end positions must be so far removed from the rest position or the stop position that a residual clamping stroke remains which insures safe clamping even then in the terminal clamping positions. The terminal clamping positions are different for chucks of varying sizes, and so are the clamping strokes. To adjust the end positions as well as for determining the attainment of these end positions, an apparatus is provided comprising a transmitter device and a sensor device which reacts to approach or contact. Spacing is changeable with the adjustment of the clamping jaws. In order to prevent accidental erroneous adjustment, at least one specific part of the transmitter or sensor device is associated with each clamping unit and is changed with or made to function with its corresponding clamping unit.

Abstract: A series of decals are attached to an elongated web (20) and are spaced a generally constant distance apart in the direction of the length of the web. The machine includes supply and take-up spindles (28, 30) for rotatably supporting reels (27, 29) for the web, and a web drive (48, 49) for moving the web from the supply reel (27) to the take-up reel (29). A mandrel rotatably supports the article (23) and a movable head (33) presses the web and the decal against an article on the mandrel. The web passes from the supply reel (27), between the mandrel and the head (33), and to the take-up reel (29). The machine further includes a brake (42) which, when engaged, holds the web against movement, and a decal sensor assembly (41). After the machine is actuated to cause the movable head (33) to press the decal against an article (23), the brake (42) is actuated to release the web, and the web is then pulled across the article. The moving web rotates the head which in turn engages and rotates the mandrel. The article revolves with the mandrel and the decal is rolled onto the article. The decal sensor assembly controls the operation of the brake to enable advance of the web during and after application of each decal.

Abstract: If circuit comprises a relay (RA) provided with a contact (CA) establishing a circuit for heating the electrodes (e1 and e2) of the lamp (F), then cutting this circuit so that a ballast (B) generates an overload igniting the lamp. It is characterised in that the relay (RA) also carries a contact (CC) bringing into circuit a device for gradual control (CG). The relay (RA) is controlled by a circuit for temporising and synchronising in such a way that the moment of operation of its contacts causes clean ignition of the lamp (F) and immediately brings into use the device for gradual control, under conditions such that the latter can intervene only on a first complete half-wave of the voltage at its terminals.
