Patent DE-3039617-A1 (DE)
Inventor: BLEICHER MANFRED
IPC: B23B45/16
Filed: 1980-10-21
Abstract: A hammer drill with an air-cushion percussion mechanism (18) is proposed. The percussion mechanism (18) has a cylindrical skirt-type piston (39) reciprocating in a guide. Arranged in the bore of the skirt-type piston is a piston-like striker (41) which is carried along by the skirt-type piston (39) via a closed air cushion. In its frontmost position, the striker (41) strikes a coaxially arranged intermediate anvil (48) which transmits the energy delivered by the striker to the tool (5) of the hammer drill. The intermediate anvil (48) is located in a guide sleeve (46), which at its end remote from the tool (5) has an axial stop (53) for the intermediate anvil (48). The guide sleeve (46) is solidly supported to the front - in the direction of the tool - and elastically supported to the rear. The outside diameter of the guide sleeve (46) is less than the inside diameter of the inner space of the skirt-type piston (39). At least in its frontmost position facing the tool, the wall of the skirt-type piston (39) overlaps the guide sleeve (46). In this way, a hammer drill is created which is distinguished by a very compact type of construction and a very low weight. Lubricant losses and the ingress of dust are prevented by the arrangement of the intermediate anvil. Drilling impact effects on the housing and thus on the operator are reliably avoided. <IMAGE>

Title: Gloves for hand care
Inventor: KNOELL GEB RUFF
IPC: A61F13/10
Filed: 1981-01-21
Abstract: Many different occupational groups such as building workers and those working with machines, those engaged in medical professions or housewives often suffer from chapped hands with cracks. Treatment with a hand care composition usually entails unpleasant side effects such as prolonged absorption of the care cream, or the time or opportunity to rub cream into the hands is lacking. This is why the invention proposes gloves for hand care with which it is possible easily and without difficulty to carry out a beneficial course of hand care when they are worn over night. According to the invention, any suitable gloves made of any suitable material are provided on the inside with any suitable care substance. Gloves for hand care should be made of any suitable material such as disposable material or material which permits repeated use or has any other advantages, for example, is soft, fine, has open-pore perforations, is low cost, air-permeable, has a grease-resistant outer side etc. The gloves for hand care should be provided on the inside with a care substance in any suitable amount and consistency such as, for example, a cosmetic care cream or medicinal ointment or medicinal dusting powder in any suitable composition for a caring or curative effect. When the hands are seriously affected, the gloves for hand care represent, for example when worn over night, a real hand recuperation course. In the case of normal hand care, the glove for hand care can be used occasionally as additional intensive care supplement. The combination of care/medicinal substance in the item of clothing is thus also to be employed in any other suitable items of clothing or underclothing such as stockings, socks, pants, wrist, elbow or knee straps etc. and thus also has uses in nursing and cosmetic sectors and in medicinal treatment and in hospitals for skin injuries and burns.

Patent DE-3115760-A1 (DE)
Title: Structural element, consisting of an envelope which encloses a cavity with a filler incorporated
Inventor: BECKER OTTO ALFRED DR
IPC: E04C3/29
Filed: 1981-04-18
Abstract: Such structural elements are suitable, in particular, for building structures, for example for supporting ceilings, floor and wall structures and for load-carrying bridge, ship, vehicle and aircraft structures. The invention has the object of improving as far as possible the bending stiffness and the load capability of such structural elements. Expanding materials and solid elements of specific shape and position subdivided therein are arranged in and with respect to closed cavities. The clamping means may be of a very different type, consistency and expansion dimension. They cause, in particular, a very high longitudinal stress of the structural element, and of its parts and associated elements, supported by molecular forces. These forces are virtually unlimited within their expansion region. They thus prevent bending and kinking of, for example, beams, despite a relatively low material cost to a previously unknown extent. Particularly for the said technical fields, this results in new structural capabilities and applications of fundamental significance. <IMAGE>
