Patent DE-3138457-A1 (DE)
Title: Electrical installation apparatus
Inventor: BAUMANN PAUL
IPC: H02G3/14
Filed: 1981-09-26
Abstract: The invention relates to an electrical installation apparatus, especially a socket, having a cover which is arranged such that it can pivot and, in its closed position closes a retaining space, which is surrounded by a cover, for a plug, switch or the like. The invention is intended to achieve the object of connecting the cover to the apparatus in a manner which is structurally as simple and elegant as possible and using fewer components than in the past; in addition, the cover is also intended to provide the capability of maintaining the open position, or of remaining in this position, if necessary, until it is intended to return into the closed position again. This object is achieved according to the invention in that the pivoting connection between the installation apparatus and the cover is at least one U-shaped spring bracket whose web runs along the cover edge and is held thereon, while its limbs are guided through the cover and are guided along behind it such that they can be tensioned; in this case the construction of a cover edge in the region of the pivoting connection provides the precondition for the cover to have a design, e.g. a chamfer on the outside of the cover edge, which allows it to latch in its open position without being held manually. <IMAGE>

Patent DE-3149635-A1 (DE)
Title: Spring-operated snap fastening
Inventor: VOLK SIEGFRIED ING GRAD
IPC: E05C19/02
Filed: 1981-12-15
Abstract: Spring-operated snap fastening for doors and flaps on furniture and appliances, such as television receivers, have ejector springs which are tensioned via an ejector bolt during the closing of the door. Under renewed pressure on the door, a catch mechanism releases the ejector bolt which is retained when the door is in the closed state and which opens the door ajar as a result of the spring force. To ensure a fastening which allows the door to be opened only by pressure on the door, it is proposed to make the ejector bolt round and supported in a hollow cylinder and to impart to this a positive rotation through 90 DEG  both during closing and during opening by means of a single-step, two-step or cam mechanism. The catch head of the ejector bolt is designed as a rotary toggle fastening and, during rotation into the closing position, engages with undercut edges behind correspondingly formed catch projections on the receptacle on the door.

Title: Support and transport device for goods to be dried
Inventor: WAGNER MAX
IPC: F26B15/14
Filed: 1983-06-15
Abstract: The device is for goods such as ceramic mouldings, wood or the like in a drying chamber (6) with a plurality of drying zones (8) which are differently air-conditioned. The problem arises in such drying chambers that the differently conditioned streams of drying air intermix in an undesirable way at the transition points between two drying zones (8). To solve this problem, the invention provides that the pallets, troughs or the like, which are guided in the transport frame (4) of the support and transport device, have vertical rims (12,13), at one or both the end sides situated transversely to the direction of transport (10). The rims project downwards and/or upwards to an extent such that they respectively close, except for a small gap (14), the interspace between the pallets (1,2,3), arranged one above the other at different levels, and the intermediate cover (9). The length of the pallets (1,2,3) is adapted to the length of the drying zones (8), so that at the transition points between two drying zones (8) the rims (12,13), standing one above the other, together with the structure-side bulkhead (7) known per se, form a partition which is impermeable to the drying air stream. To maintain the sealing action and to reduce the warping of the free front pallet ends, the invention further provides that the pallets are... horizontally in a detachable manner by a flexurally stiff coupling in the form of a plug coupling or the like ...

Title: Process and device for at least two-stage injection moulding of composite mouldings from polymers, as well as application of the process
Inventor: SCHOETTLI THEODOR
IPC: B29C45/04
Filed: 1983-07-05
Abstract: For manufacturing a moulding composed of at least two polymers with different properties, in a first process step a first liquid polymer is introduced with cooling, for example by means of a feed device (20), into a heated injection mould. This polymer is allowed to remain there until it achieves sufficient dimensional stability for further process steps to be carried out. The temperature of the first polymer and/or the residence time are adjusted in such a manner that crosslinking of the polymer still does not occur. Subsequently, in a second process step, a second liquid polymer with properties different from those of the first polymer is introduced into the heated injection mould with cooling, for example by means of a feed device (24). The first and the second polymer are then crosslinked together in the injection mould heated at least to crosslinking temperature. An inseparable bond is thus formed between the two in the areas adjacent to one another. <IMAGE>
