Title: Meat mincer - has structured passage for hard pieces to prevent clogging and stoppage
Inventor: UMHOEFER WOLFGANG
IPC: B02C18/30
Filed: 1991-05-15
Abstract: The outlet tube of a meat mincer has at least two sections (25,32) which are on the same axis and rotate in relation to each other. Each has at least one axial drilling (36,37) through a lateral wall (34,35) for the hard pieces. The passage openings (36,37) in the lateral walls (34,35) of both tube sections (25,32) are pref. identical in their radial location, size and shape. The lateral walls (34,35) of both rotating tube sections (25,32) are brought together. The lateral wall (34) next to the disc (18) with the fine holes and the support ring (27) is chamfered to form a cone in the direction of travel by the hard pieces. The outlet tube (32) rotates in the support ring (27) and its lateral wall (35) has only one opening passage (37) for the hard pieces. ADVANTAGE - The machine gives an effective mincing action on the meat, without blockages through hard pieces which could clog the openings for the minced softer meat.

Title: Car hard-top locking mechanism - has face deflecting support to engage locking member in recess
Inventor: SCHUCHMANN REINER
IPC: E05B81/20
Filed: 1991-07-26
Abstract: The locking member (4) is movable in the wall opening of a support (2) and longer than the opening. In the free position it protrudes from one side, and in the working position from the other, engaging in an opening in an adjustable locking component (1). After this opening (9) has been moved in front of that (3) in the support, the component is locked by moving the support against a deflector face (20) on a locking body (10), causing the member to engage in the opening (9). After further movement of the support in the same direction, a locking face (21) on the body prevents movement of the member into the free position. USE/ADVANTAGE - Movement of locking component over greater distance while keeping its length in this direction short.

Title: Prodn. of window in casing wall - by making hole with e.g. annular groove in wall, inserting O=ring in groove, and injection moulding window into groove and flush with surfaces
Inventor: BEHRENDT HORST
IPC: H05K5/06
Filed: 1991-07-31
Abstract: The wall of a casing and partic. one of a box to hold electrical or electronic components, is produced with a hole and an injection moulded inspection window over that hole. The rim of the hole has a circumferential groove or shoulder, in or on which it holds an elastic sealing ring; the window is then injected so that it lies against the ring and compresses it in doing so. Pref. the box has a cover (2) held on by four corner screws (3). At its centre the cover (2) has a circular hole (2c) with a circumferential groove (2a) running all round. This groove (2a) holds an O-ring (5). The inspection window (4) is injection moulded in position so that its faces are flush with those of the cover (2). The window (4) has a circumferential rib which fits against the O-ring (5) and thus fills the rest of the groove (2a). This window (4) is injection moulded in position; when it subsequently shrinks it is still sealed by the ring (5). ADVANTAGE - The method makes a tight joint between the seal and window, even if the window is made of a different material from that of the casing itself.

Title: Layered material - has a fused bonding layer between porous, sintered carrier and solid function layers
Inventor: WEGNER KARL-HEINZ
IPC: C23C4/08
Filed: 1992-06-26
Abstract: The layered material with a sintered and porous carrier layer and a thermo-kinetic cladding for the solid function layer, has a bonding layer (4) between the carrier (2) and function (3) layers, of a material which bonds the layers (2,3) together through the energy developed in the cladding action. Also claimed is a mfg. process where the function layer is placed over the particles of the carrier layer to be sintered, of a material which bonds with them at a suitable temp. and kinetic energy. The outer surface of the particles layer is softened to form a solid bonding layer so that it is forced in to the carrier layer when kinetic energy is applied. The carrier layer (2) is of sintered metal with emergency running characteristics and the function layer (3) is a sliding metal material. The bonding layer (4) is a common fusion of the materials of both layers (2,3). The components of the layers (2,3) layer which do not melt and/or melt at high temp. are dispersed to lie within the bonding layer (4). The components of the layers (2,3) which cannot be separated and mixed when melted are deposited within the bonding layer (4), as fine particles of a dispersion alloy. Where the carrier layer (2) is of tin bronze and the function layer (3) is an aluminium lead dispersion alloy, the bonding layer (4) contains a solid aluminium copper base alloy. USE/ADVANTAGE - The material, such as for sliding components, can be a aluminium or alloy cladding on a porous carrier layer, with an effective bonding between the layers.
