Title: Stacking machine for laminations of different sizes - uses interchangeable head or multiheads on sliding carriage with to-and-fro movement
Inventor: MACCHIONE JOHN MICHAEL
IPC: H01F41/02
Filed: 1973-08-17
Abstract: The stacking machine which can adapt laminations of different sizes, has head holding laminations of the same size ready for insertion into a coil bobbin and facilities for carrying the laminations into the bobbin with a back- and forward-movement. It further provides a mount-base for fixing the head with adjustment facilities to define the positioning. A reciprocating drive engages releasable with a sliding carriage onto which the mount-base is fixed for the back- and forward-movement of the hadss. The arrangement is such that the head can be dismantled from the mount-base easily and be replaced by a head for laminations of another size. The travel distance of the carriage can be selected in predefined steps to obtain the required throw for laminations of different sizes. By using a mount plate with several heads, each carrying laminations of a different size selective insertion of different size laminations into the coil bobbin is possible.

Title: Domestic oven built in to kitchen furniture - has pivoting door handle which is flush when not in use
Inventor: SCHEMBERA FRIEDRICH
IPC: F24C15/02
Filed: 1973-12-24
Abstract: The oven is flush with a range of kitchen furniture and has a door which hinges about its bottom edge. The door has a handle pivoting about a hinge pin. The sides of the handle have recesses which slot over a fixed pin. The handle with the hinge pin can be pressed down against a spring so that the fixed pin slips out of the recesses and slides over the curved flanges of the handle sides leaving the handle free to pivot about the hinge. When not in use the handle is flush with the door, making a clean line of kitchen fittings, but when moved out it is away from the heat of the oven.

Title: Rotor for inductive sensing element - consists of ferro-magnetic strip mounted on rotatable element
Inventor: GOOSSENS ANDRE F L
IPC: G01D5/14
Filed: 1974-01-28
Abstract: The strip is moved near the sensing element in accordance with the motion of the rotatable element, and its reluctance with respect to the sensing element periodically varies. The strip ends are joined together by an expandable element, so that the strip can be put under tension on the rotatable element; the connecting element consists of a thin piece of non-ferromagnetic metal sheet. The connecting element is welded to the strip at its ends, and its middle part is narrower than its ends. In an alternative arrangement the ends of the strip or expandable element may be hooked over teeth on the rotor, to give a weldless fastening.

Title: Self cleaning domestic water tap filter attachment - has coarse filter and two fine filters together with aeration channel
Inventor: WEHBERG PETER-OTTO
IPC: E03C1/084
Filed: 1974-05-02
Abstract: Filter for water tap is screwed into the pipe, has a widening, for centring the attachment rubber washer, a coarse filter, and two fine filters. One fine filter is curved against the flow of water. An air suction channel, on the periphery of the other fine filter, has openings at the side of the curved filter, on its lowest point. When the tap is turned on full, the air channel, will aerate the water. When the tap is being turned off the fall in suction will cause the water to flush dirt particles from the filter through the air channel. This only leaves the coarse filter to be cleaned periodically.

Title: Tunnel kiln with preheat zone - having supplementary heating the temp. of which can be controlled along zone
Inventor: WOYCZECK GUENTER ING GRAD
IPC: F27B9/36
Filed: 1974-08-28
Abstract: Tunnel kiln has stepwise pushing of fired material throu. it, with additional heating applied between the individual stacks of good for firing. The temp. of the combustion products used for this additional firing can be adjusted at different stages along the zone. Additional heat is provided by burner chambers along the zone fed by a common air and fuel system but eith individual control valves on each burner. For firing articles. The use of preheaters is known but they have the disadvantage that overheating of the gap between the stacks can occur causing non-uniform heating of the fired goods with damage or dislocation of the stack. By controlling the raste of heating along the zone this problem is avoided.

Title: Hydraulic pressure testing of pipes - including compression resistance and tightness testing of welding joints and pipe proper
Inventor: BRAUN HANS ING GRAD
IPC: G01M3/00
Filed: 1974-09-12
Abstract: The hydraulic pressure testing system is especially for pipes and consists of a cylindrical body (16, 20, 21, 30) with a cross-section smaller than the inner cross section of the pipe piece to be tested (34). The cylinder has two elastic sealing rings (18, 28) blocking the space between the outer surface of the cylinder and the inner surface of the pipe. In the rest position the inner surfaces of the rings roughly correspond with the cylinder surface, but in the working position press firmly against the inner wall of the pipe. A pressure testing space (38) is thus created between the two rings in the form of a narrow, hermetically sealed coating around the cylinder.
