Title: A bar loading magazine
Inventor: FOHL ARTUR
IPC: B23Q7/10
Filed: 1966-11-25
Abstract: 1,120,000. Blanks transferring. REMSWERKE CHRISTIAN POLL & SÍHNE WERKZEUGUND MASCHINENFABRIK K.G. 25 Nov., 1966, No. 52863/66. Headings B3B and B3H. A bar loading mechanism for a working machine such as a lathe or swaging machine, comprises a receiver 11 for holding the bars 12 side by side, means 14, 34, 35 for feeding the bars horizontally, axially and in a direction 50 parallel to the bars in the receiver, an outlet runway 15 from the receiver inclined downwardly towards the feeding means, a stop surface 15a engageable by the lowermost bar in the receiver, and an eccentric roller 17 rotatable to lift the lowermost bar over the stop surface 15a and on to the runway 15. The bars in the receiver are located axially by a forward abutment surface 13, and a pair of runways 15 are adjustably supported on bearing blocks 10 mounted on pedestals 1, 2. The height of these blocks is adjustable by a hand wheel 4 and they carry grooved rollers 14 for receiving the lowermost bar 12 from the runway 15. Two lifting eccentrics 17 carried by the blocks 10 are rotated in unison by shaft 23 driven through chain (22), Fig. 4 (not shown), by a driving unit (20). After raising the lowermost bar the eccentrics 17 are lowered and this causes spring-loaded pressure rollers (33) to press upon the bar 12 then located on the rollers 14. These pressure rollers are driven by unit (20) and their height is adjustable by screws (29). The formed end of the bar 12 is gripped against a driven feed roller 35 and fed forwardly thereby to the second feed roller 34. Both rollers 34, 35 are driven by a further driving unit 37, Fig. 2 (not shown), and have resilient counter pressure rollers 33 acting from above. The bar is thus fed axially to a clamping device 47 of the working machine 52. When the end of the bar passes a roller switch 49 a further feeding step is initiated. The length of a bar fed into the machine may be controlled by switches 46 driven by a switch disc 45.

Title: Jib sail raising system
IPC: B63H9/10
Filed: 1971-11-16
Abstract: 1336192 Raising jib sails HOOD SAILMAKERS Inc 16 Nov 1971 [19 Nov 1970] 53040/71 Heading B7V The luff of a jib sail 15 has a bead 16 so that it can be retained within a stainless steel forestay 13 of C-shaped cross-section. The opening of the C-section is relatively wide at the lower end of the stay (Fig. 3) to allow the bead to enter the stay interior. Two part spherical guide members 31 and 33 are held by a bracket 27 at the lower part of the stay 13 so that during raising of the sail the bead approaches the stay at a shallow angle to inhibit binding of the bead in the entrance to the stay. For the same reason, a C-shaped guide member 45 is provided and is secured to the boat by a flexible link 47. The bead 16 may be formed by a plastics rod located within a sailcloth tape which is sewn to the luff of the sail proper. To reduce friction between the bead and the tube, the tape may include threads of polytetrafluoroethylene. The rod may be wrapped with double -backed adhesive tape to avoid relative sliding of the rod and sail. In modifications (not shown) the bead guide members 31 and 33 may be replaced by wheels or rollers.

Title: Entranceway closure system with means for object detectio
IPC: B66B13/26
Filed: 1974-12-09
Abstract: 1495394 Door control mechanisms WESTINGHOUSE ELECTRIC CORP 9 Dec 1974 [18 Dec 1973] 53093/74 Heading E2M An object detection door control mechanism, particularly for a lift car door, comprises a radiant energy (preferably infra-red) source (60, 64) mounted on the door and directing a beam outwardly from the door onto a sill portion 74 of the entranceway and detector means (62, 66) mounted on the door and directed at the sill portion to receive radiation scattered from the sill portion in a direction parallel to the door edge: interruption of the beam causing the door to stop closing and reverse. As shown centre-opening sliding lift car doors 5, A5 are moved by an electric motor 25 via a lever and link mechanism and each door is provided with source and detector means. Each source  comprises two transmitters (Tl, T2, T3, T4) which intersect the sill portion at discrete points (78, 80, A78, A80) and each detector means includes two detectors (D1, D2, D3, D4) each directed at different point to define an inner R70 and an outer R68 detection beam spaced from each door edge. The surface of the sill portion must be such as to scatter the incident energy (i.e. rough bronze or aluminium oxide in epoxy resin binder) so that the angle of incidence of each beam is not equal to the angle of reflection of the detected beam. As the doors come closed limit switches L1, L2 are actuated in turn to render first the inner (D2, D4) then the outer (Dl, D3) detectors inoperative. In addition each detector means may direct two additional beams to the sill of the lift car (Fig. 5 not shown) each being detected by an additional detector on the car door. The doors are controlled through out their movement by a system of cams driven off the motor which act on control and limit contacts of a control circuit (Fig. 4 not shown) to stop the motor and to vary the motor armature resistance, accelerating the doors from rest and slowing them down progressively as they approach rest.

Convention dates, Feb. 10, 1938, and April 11, 1938. [Classes 72 and 82 (i)] Steels or alloy steels of great purity are obtained by acting upon the steels &c. containing an energetic reducing agent such as silicon, titanium or zirconium whose oxide has an acid character with a slag containing principally alumina and alkaline or alkaline earth bases, the process being carried out in such a manner that the final step contains a very small proportion of iron oxide of 1 per cent. or less and manganese oxide. The initial slag also contains silica, the proportions of the constituents of the slag being such that the silica content of the final slag is less than 30 per cent., the alumina being at least 20 per cent. The process may be carried out in an electric or open hearth furnace or in a converter or as described in Specification 404,300. A synthetic slag of the desired composition may be formed previously and then charged into the furnace, or an existing slag in the furnace may be removed and the constituents of the slag added to the molten bath into which is also introduced the reducing agent; or the final slag may be used again by adding alumina and/or alkali or alkaline earth bases to bring it to the desired composition, or when the manufacture of the steel has taken place in an electric furnace aluminous and/or alkaline or alkaline earth bases may be added to the existing slag. The action of the reducing agent is stated to introduce aluminium into the steel &c. by the reduction of the alumina. To obtain alloy steels, oxidic compounds of the alloy ingredients are introduced into the slag. these compounds being reduced by the reducing agent. Specification 463,132 also is referred to.
