Title: Improvements in or relating to electromagnetic relays
IPC: H01H50/36
Filed: 1944-08-01
Abstract: 584,278. Electromagnetic relays. ERICSSON TELEPHONES, Ltd., and CROWE, D. C. Aug. 1,1944, No. 14664. [Class 38 (v)] An electromagnetic relay comprises three parallel core-like members 1 and 2 arranged in the form of a triangular prism with a backplate 4 at one end and an armature 6 at the other and supported by two of such core-like members and adapted to be attracted towards the third. Fig. 1 shows an arrangement comprising a major member 1 and two minor members 2 of magnetic material such as silicon wire. The armature 6 is pivoted on the reduced ends of the minor members which protrude from a magnetic bridgepiece 8. The armature is provided with holes large enough to allow it to rock freely, and is kept in place by a spring 9 attached to the armature and engaging in annular grooves in the minor member 1. An extension 11 on the armature operates two sets of contact springs 7, one arranged behind the other and of the type disclosed in Specification 576,608. Fig. 9 shows the method of mounting a number of relays 17 with their contact spring assemblies 7 on bars 12. In alternative layouts all three members are provided with mutually assisting windings. Alternatively one of the minor cores is wound, the other being formed of non-magnetic material, If a slow relay is required, a copper slug or short circuited winding may be placed on either a major or minor member. In a shunt field relay one minor member is permanently magnetized and a reversal of current in a coil on the other minor member will cause the two fields in them to oppose each other thus forcing flux through the major member to operate the armature. An alternating current relay can have the minor cores wound and the bridge replaced by non- magnetic material or omitted. The armature may be magnetically split as shown in Fig. 8 where the two magnetic portions 14, 15 are separated by a non-magnetic portion 16. By connecting a condenser to one minor core the relay will operate without chatter. The Provisional Specification describes a polarized relay which may be formed by omitting the bridge and pivoting the armature about a vertical axis so as to leave gaps between it and the ends of the minor members. In this case the minor members would be wound and the major member would be a permanent magnet.

Title: An improved machine for stripping palm nuts and like fruits from their stems
IPC: A01F11/08
Filed: 1920-06-02
Abstract: 156,049. Smith, R. A. June 2, 1920. Thrashing-machines.-A machine for removing palm and like fruits from the stems comprises a moving surface by which rotary motion about its axis is imparted to the bunch of fruit. An endlees belt may be employed, the fruit being retained thereon by a grid or plate. In another form, the moving surface takes the form of two or more rollers 15, Fig. 2, forming a trough and rotating in the same direction. The bunches are guided to the drums by a plate 19, the fruits falling through to a slope 20 and conveyer 21, and the stalk being expelled periodically by a sliding grid 22 which is moved along the rollers at intervals. A further drum 16 prevents the bunch being carried round by the drum 15. Each of the rollers 15 may be divided longitudinally into sections, which are rotated at different speeds, means being provided to move the bunches along the rollers continuously to increase the speed of rotation of the bunch. The moving surface may take the form of a disc over which a radial retaining-roller is mounted. Increasing speed may be obtained by moving the branches towards the circumference of the disc. This action may be rendered automatic by arranging the roller in the position of a chord instead of radially.

Title: Improvements in or relating to photographic cameras

Filed: 1947-06-06
Abstract: 630,636. Photographic cameras. KODAK, Ltd. June 6, 1947, Nos. 15046 and 15047. Convention dates, June 6, 1946. [Class 98 (i)] A camera focused by moving a member carrying or attached to a carrier of the light sensitive material and adapted to receive interchangeable lenses of different focal lengths includes a series of focusing scales graduated for the several lenses and a plurality of similarly adapted cams to adjust the movable optical element of a rangefinder and/or to compensate a viewfinder for parallax and means for moving the scale and cams into operative position according to the lens in use, the focusing movement of the member causing adjusting movement of the cams and movement of the appropriate focusing scale which is read against an index. Fig. 1 shows a folding camera in which the film-carrying frame member 2 is supported by two lateral slides 3 secured in guides 5 for focusing by arms 25 on a shaft 26 rotated by gear and sector 23, 24 and engaging pins 28 on the slides. Transversely slidable on the top of frame member 2 is a slide 36, Fig. 2, bearing focusing scale 37, 38, 39, each corresponding to a particular lens and one registering with an aperture in the casing carrying an index against which the focused distance is read. Upstanding portions 40 on the slide and lugs (not shown) on the camera permit transverse movement of the slide to change the scale only when the latter is in the " infinity " position. Also carried on the frame 2 and connected to the slide 36 by a linkage 107, 109, 112 so as to be laterally moved therewith is a slide 71 bearing cam surfaces 66, 67, 68, alternatively engaging a cam follower for correcting the viewfinder for parallax, and cams 97, 98, 99 alternatively engaging a follower for adjusting a coincidence rangefinder. Each cam is suited to the particular lens in use and when the appropriate scale is positioned before the index, the appropriate cams engage the two followers, the viewfinder and rangefinder being mounted on the top of the camera. Instead of being moved by a linkage the cams may be carried on the same slide as the scales. The viewfinder, Fig. 3, comprises a rotatable lens 52 having a rectangular frame and held in two positions of rotation at right-angles by a ball 56. An eye-piece 59 is carried by an arm 62 on a rod 63 the end 65 of which is a follower engaging one of the cams 66, 67 or 68 to adjust the eye-piece 59 for parallax as the frame 2 is moved longitudinally for focusing. The rangefinder, Fig. 7, comprises objectives 80, 81, prisms 85 and 88 and a central prism system. The prism 85 is on an arm 86 pivoted at 87 and held by a spring 90 against an adjustable stop 91, Fig. 4, on a bell-crank 96 pivoted at 94 and having a follower 95 engaging one or other of the cams 97, 98, 99 to rotate the prism 85 to effect coincidence as the frame 2 moves for focusing. Either the viewfinder or the rangefinder may be omitted. Specification 630,637 is referred to.

Abstract: 599,250. Electromagnetic switches. WILLIAMSON, S. Sept. 14, 1943, No. 15062. [Class 38(v)] [Also in Group XX] In an arrangement which may be used to stop the action of a cinematograph camera shortly after a gun has ceased firing or for controlling the operation of a guillotine for separating photographic prints shortly after the web of paper has reached a certain point the de-energisation of a magnet 7 causes a circuit 11, 12 to be opened after a delay determined by a wheel 14 which has been clutched to a driving mechanism by the de-energisation. In the form shown, closure of a master switch 6 energises the magnet 7 which attracts its armature 8 to close at 11, 12 the circuit to a motor 1 driving a shaft 4 and to withdraw the disc 14 so that a slot 16 is free from the shaft 4 and a spring 15 rotates the disc to a starting position in which a stop 17 engages an adjustable stop 18. On opening the switch 6, the magnet 7 is deenergised and the periphery of the disc brought into engagement with the rotating shaft 4. Then after a time interval the notch 16 reaches the shaft, the armature tilts still further and the contacts 11, 12 open.
