Abstract: A pump for dispensing fluids and like media, having a pump casing including structure forming a counter locking means, a pusher for operating the pump, movable from a rest position into the pump casing to deliver a pumping stroke responsive to manual depression of an operating surface formed in an end face of the pusher, a locking mechanism for the pusher formed by the operating surface and a locking portion rigidly affixed to the operating surface, the locking mechanism being pivotally attached to the pusher to enable movement of the locking portion into and inwardly of a locking position relative to the counter locking means of the pump casing, whereby each pumping stroke must be preceded by pivotal movement of the locking mechanism, and, resilient structure for automatically urging the locking portion outwardly, into the locking position, after each pumping stroke, whereby pressure exerted upon any portion of the end face other than the operating surface will be ineffective for accidentally operating the p

Abstract: A pick-up arm assembly for a record player comprises a pick-up arm mounting, a counterbalance device which includes a counterweight and which is mounted to the pick-up arm mounting so as to be pivotable about vertical and horizontal axes, and a pick-up arm comprising a tube having sound pick-up means disposed at one end and an insert fitting means disposed at the other end. The insert fitting means is capable of being received by the counterbalance device to enable the pick-up arm to be removably fitted to the counterbalance device. The counterweight is mounted in the counterbalance device so that it is substantially horizontally displaceable with respect to the horizontal pivot axis, and adjusting means is arranged at the end of the pick-up arm remote from the sound pick-up means to enable substantially horizontal displacement of the counterweight to be effected when the insert fitting means is fitted to the counterbalance device.

Abstract: A method and apparatus for the foam-encasing of refuse, through the intermediary of which refuse being dumped may, in a simple and satisfactory enclosed manner with respect to the surroundings, be transported, stored and further processed. In the method the refuse or the like is compacted and foam-encased by an all-encompassing closed-cellular foam material layer so as to form a predetermined completely defined three-dimensional body. The apparatus for carrying out the method is constructed, in one embodiment, so as to consist of a closed form constituted of a plurality of form elements, which are adapted to be separated from each other, for the compacting and foam-encasing of the refuse or the like, and in whose walls there are distributed a plurality of nozzles for the infeed of the foam materials into the form.
