Title: Deflection member for a seat belt in a car
Inventor: RAMCKE WILHELM ING GRAD
IPC: B60R22/18
Filed: 1981-05-23
Abstract: Three-point belts are nowadays the most widespread construction for seat belts for the occupants of cars. In this construction, the elastically retracting upper belt (shoulder belt) is passed through a deflection member secured to the vehicle body. The invention offers a solution for reducing as far as possible the friction on the belt-contacting leg of the deflection member in that this leg is provided with a rotatable sleeve made of plastic and having a low sliding-friction coefficient. To further decrease the bearing surface and hence the sliding friction, the rotatable sleeve can be rippled on the outside and/or inside and be made from plastics having a correspondingly low sliding-friction coefficient. The sleeve according to the invention is either pushed with the aid of a spiral slot in the longitudinal direction onto the deflection member in a rotating manner or it is composed of two halves which can be closed by means of a film hinge and snap fastener. The resistance of the sleeve is such that a permanent deformation of the sleeve occurs in the event of a crash and, as a result, the stress on the belt system can be demonstrated.

Title: Shaft mounting device
Inventor: SWEARINGEN JUDSON S
IPC: G01L5/12
Filed: 1981-06-09
Abstract: A device for matching and measuring the axial loads on a shaft which is mounted such that it can rotate, in the case of which device the axial load occurs in one of the two axial directions. The shaft (14) which is supported such that it can rotate has two shoulders (42, 44) which point in opposite axial directions and interact with a pair of axial bearings in order to restrict the shaft to a limited axial movement range. Axial bearing rings (50, 58) which interact with the shoulders are located between the shoulders and the bearings (48, 56) and are prestressed in the direction of the bearings by elastic parts (54, 62) which resist the axial movement of the shaft between the bearings. Detection systems (66) are provided in order to measure the axial displacement of the shaft (14) and to provide an input for an axial load indication (70) and control systems (36, 74, 80). A method for preventing damage to the labyrinth seals of the shaft during starting of the equipment is also provided. The system is used to protect the bearings against being overloaded and also to prevent overloading of the labyrinth seals. <IMAGE>

Title: Animal house for small animals, for example cats, or, in enlarged form, playhouse for children
Inventor: WOERLE SIEGMAR
IPC: A47D11/00
Filed: 1982-10-01
Abstract: The invention can be used in the zoological sector and also in the toy sector. The technical problem of the invention is to provide, especially for small animals, an accommodation which is as closed as possible on all sides and in which they can feel safely hidden, whilst the handling and production of the house will be simple. However, at the same time, all hygienic requirements must be satisfied. This object was achieved in that the house consists of a piece of single-layer or multi-layer cardboard or plastic stamped out in a particular shape. During assembly, this is bent to shape at embossings (12) and joined together by means of plug-connection incisions (6) to form the shape of a rectangular house. Some features typical of this invention are thereby formed. These are the lateral roof projections (7), the gable projection (9) over the entrance (8) and the gable pegs (1) which pass through (3) the roof halves (13). The floor of the house is an independent unit which can be plugged together, and can be pushed in from the underside of the house. The technical sector embraces cardboard box construction. <IMAGE>
