Abstract: 743,547. Electromagnetic relays. TELEFONAKTIEBOLAGET. L. M. ERICSSON. May 29, 1953 [May 30, 1952], No. 15029/53. Class 38(5) An electromagnetic relay, particularly for use in a telephone exchange, comprises a magnetic circuit formed by a frame 15, and an angle piece 2 to which a core 9 is fixed by nut 1, and with which cooperates an armature 4 mounted on pivot lugs 27 and carrying an additional member 5 that, in the attracted position of the armature, engages lug 15 projecting from the frame so as to determine the length of the air gap 26 between the armature 4 and the pole surface 10 of core 9. The additional member 5. which is optionally magnetic, rests on the armature pivot lugs 27, and, with the armature, is held in position by a spring 20 tensioned between a hook 3 fixed at the angle piece 2 and the end of a tongue 32 which projects from additional member 5 and can be bent to alter the tension and thereby the release force of the armature. A bendable tongue 16 projecting from the frame 14 forms an adjustable back stop for the additional member. At its upper end the additional member 5 is fixed to the armature 4 by a screw 7 rotation of which, by altering the distance between the armature and additional member, varies the length of air gap 26. A scale on the additional member around screw 7 may indicate the air gap length directly. Three spring assemblies, Fig. 4 (not shown), are held between the frame 14 and angle piece 2 by springs at the top of each assembly. The contacts are operated by lift strips 19 which rest on the additional member 5. To adjust the attracting current the additional member 5 may be made to move a member loaded by a spring attached to a further adjustable tongue on frame 14, Fig. 5 (not shown). The attracting and release time may be varied by changing the size of pole surface 10. The enclosing frame 14 and and angle piece 2 form a magnetic screen.

Title: Improvements in and relating to the manufacture of die-moulded articles of laminatedfibrous materials
IPC: B27M3/10
Filed: 1942-10-31
Abstract: A method of moulding articles of varying cross-sectional area, e.g. propeller blades, aerofoils, struts and spars for aircraft, &c., from fibrous lamin  provided with an adhesive comprises cutting a plurality of lamin  smaller than the respective cross-sections of the moulding space, providing the lamin  at some stage in their manufacture with an adhesive, which may be in liquid or solid form, assembling the lamin  in parallel to form a core, arranging other fibrous lamin  provided with an adhesive to form a skin around the core, and applying pressure, or pressure and heat.  The size and shape of the core and skin lamin  are so chosen that after their compression they fill the mould.  The density of the skin may be higher than that of the core.  If local bulges or particular contours are required, a fibrous filler, such p  as pulp, may be used.  Groups of lamin  may be united to boards to form intermediary components which are bonded together in the finished article.  The lamin , the boards or the article itself may be densified by pressing to a greater degree than that necessary for bonding or moulding.  The fibrous lamin  may be interleaved with metallic layers, thin foil, wire netting or solid films of adhesive.  One or more lamin  or groups of lamin  of high density may be arranged in a core of low density.  Hollow articles may be produced by moulding around a removable mandrel; the hollow thus formed may be filled with low-density material. Lamin  or groups of lamin  may be arranged between the mandrel and the laminated body, to provide a skin in the hollow.  The mandrel itself may consist of bonded fibrous lamin enveloped in covering lamin  according to the invention.  The fibrous lamin  may be of wood, paper or textile fabric.  The adhesive may be a natural resin or glue, or a synthetic thermoplastic or thermosetting binder, or a cold-setting phenolic resin.  According to the Provisional Specification the lamin  may be heated, prior to moulding, in an oven, and during moulding by a high frequency electric field.

Patent GB-167914-A (GB)
Title: Improvements in sheet feeding machines
IPC: B65H1/14
Filed: 1920-06-11
Abstract: 167,914. Mills, C. K., (Dexter Folder Co.). June 11, 1920. Sheet-separators; pile tables and supports for sheet feeds.-A sheet-feeding device is constructed with pile-raising means attached to the opposite ends of flexible operating-means passing over shafts at the top of the standards on which the raising-means slide, so that as one pile is raised the other end of the flexible means drops to a position to receive another pile, and on a .reversal of the driving-shafts, the new pile is raised. The pile-raising means can be geared directly to a driving-motor for raising the pile quickly, but normally when the sheets are being advanced automatically this drive is disconnected and the pile-raising means are operated by ratchet mechanism brought into action only when the sheet-forwarding suction devices have to drop more than a certain distance to engage the top sheet. As shown in Fig. 2, the pile-supporting means is arranged between standards 2 on sockets 1, and comprises chains 6 passing over sprockets on shafts 4 and connected at each end by a detachable connection 7 to rods 9 fitted with guides 14, and supporting I-beams 13 which pick up the pile-tables 15 from the position shown in Fig. 2, in which they rest on rollers 16 supported by beams 17. The rails 13 are formed with racks engaging grooves 12 in the rods 9, so that by rotating the rods 9 by levers engaging sockets 11 in a disc 10, the rails 13 can be adjusted longitudinally. The shafts 4 are driven by worm gearing from a shaft 21, which can be rotated by hand, or driven from a motor 163, or from a ratchet shaft 35 operated from a power shaft 55. To drive the shafts 4 in the direction desired, and by the required driving-means, a disc 24 is held by a locking-device 29 in one of four positions (a) in which the shaft 21 is geared to a wheel 197 driven by the motor 163 through one driving-gear 32, Fig. 2, (b) through two such gears 32, 33, (c) (d) in which the drive is connected to a gear 34 on ratchet shaft 35 by the same gears as in (a) and (b). The sheets are separated by a suction separator which is given combined vertical and horizontal reciprocating motions controlled from a cam shaft 49, on which is freely mounted a gear-wheel 50 geared by bevel-gearing to the shaft 55. The disc 50 drives the shaft 49 through a clutch which is automatically thrown out by calipering mechanism of known kind if a double feed occurs or if the sheet fed is crumpled. The ratchet wheel for keeping the pile at a uniform height is actuated by a pawl on a lever arm connected to a slotted link actuated by a crank-pin on a disc integral with the gearwheel 50. The lever can be prevented from returning under spring action by the action of a stop lever on a dog 72 fixed to the shaft 35. This stop lever is moved, when the pile is low, to permit the pile to be raised by a lever 75 on a shaft 76 which controls the vertical movements of the forwarding suckers, the action of which is assisted by blasts of air delivered from a pump.
