Abstract: 633,426. Poles. STEWARTS & LLOYDS, Ltd., and STEWART, G. B. Jan. 31, 1947, No. 3005. [Class 20 (i)]  A clamp for a built-up pole comprises upper and lower spaced plates 14, 13 with holes 16 through which principals 11 may extend, and means for effecting relative movement between the plates in the direction of the principals in order to force them to lie at an angle to the axes of the principals so that the edges of the holes bite the surface of the principals. As shown in Figs. 3, 4 the plates are drawn together by means of a central nut and bolt 19, spacing blocks 17 ensuring that the peripheries of the plates remain a constant distance apart so that the plates are deformed. Several such clamps are spaced along the pole. Those near the base, where in the case of a tapered pole the principals are relatively widely spaced, are larger than those near, the apex and may have more than one clamping bolt. As shown in Fig. 8 the clamp may be formed of a single triangular plate 14 with the apices 14a turned back through 180 degrees and spaced from the main part of the plate. The principals pass through holes 16 in the plates and apices, the apices being drawn towards the plates by means of a bolt 19 and a washer which contacts their edges. The upper ends of the principals may be secured together by a headpiece 20, Fig. 2. Secured to the headpiece 20 may be several diverging tubes 21, each carrying an insulator 22 and tied together by ties 23. The Provisional Specification describes a modified type of clamp comprising inner and outer bands which together define holes for the principals. Lateral bolts between each pair of principals are used to draw the bands together.

IPC: H04Q3/62
Filed: 1944-02-18
Abstract: 571,811. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., McCLEW, J. W., and PEARCE, O. A. Feb. 18, 1944, No. 3019. [Class 40 (iv)] In a system in which normal calls are set up over finder-selector links LL1 ... LL3 and in which the setting of a selector to one of two particular positions causes the corresponding one of two special finders SAL, SBL to hunt for the line, finders of all kinds can hunt simultaneously without interference although the marking banks of the special finders are multipled and are marked over the ordinary marking banks of the normal finders. Interference with the normal finders is prevented by providing them with a common shunt field test relay LT, the marking potential being applied over one winding and the test wiper of the allotted finder being connected to the other. This relay cannot respond to any other kind of marking. A line is marked in SAL by a connection to the grounded test relay SA and in SBL by a connection to battery over a low resistance YB, the marking in both cases being applied over a back contact of the line relay to present interference by the markings in the normal finder banks. There is no tendency for SA to operate falsely via any circuit in SBL. False operation of SB via the test wiper of SAL when the switches are in corresponding positions is prevented by making SB insensitive and including a high-resistance YA in the battery connection to the test wiper of SAL.

Patent GB-1092551-A (GB)
Title: Treating iron ore to produce a blast-furnace charge
IPC: C22B1/14
Filed: 1965-01-25
Abstract: A charge for a blast furnace is produced by separating particulate iron containing material, of which not more than 5% by weight of the particles are greater than 20 mm. in particle size, into at least one coarse fraction and a single fine fraction whose upper size limit is between 0.5 and 2 mm., this fine fraction being made into pellets which are subsequently kilned, the kilned pellets being suitable for feeding to a blast furnace.  Separation may be effected in a hot-air classifier.  If two fractions only are produced the coarse fraction may be sintered to render it suitable for feeding to a blast furnace, alternatively the coarse fraction may be separated in accordance with size to produce two fractions, the finer of these two fractions being sintered to render it suitable for feeding to a blast furnace.  Where two coarse fractions are produced the coarsest fraction may be fed directly to a blast furnace or it may be kilned in a manner similar to that used for pellets of iron-containing material, the kilned material being suitable for feeding to a blast furnace. The coarsest fraction may be mixed with some green pellets containing iron and the mixture kilned in a rotary oven.  The largest size for the finer of the two coarse fractions may be between 4 and 6 mm.  The iron containing material is preferably mixed with hot dust containing iron before or during the separation into the various fractions.  In the case of plastic ores, e.g. Minette ores, with or without iron-rich ores, e.g. haematitic and magnetitic ores, the fine fraction of upper size 0.5-2 mm. may be pelletized in drums and/or on trays utilizing water droplets to nucleate the pellets and a fine water spray to grow the pellets such that their moisture content is 14-16% by weight. With haematitic or magnetitic ores the fine fraction may be milled after drying,if necessary, before being made into pellets and the fine fraction may then be heated in a rotary furnace at 500 DEG  C. for 10-20 minutes and then at 1000 DEG  C. and at 1300 DEG  C.

Patent GB-724931-A (GB)
Title: Improvements in record players
IPC: G11B17/16
Filed: 1953-02-06
Abstract: 724,931. Automatic gramophones. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 6, 1953 [Feb. 11, 1952], No. 3413/53. Class 40 (2). In an automatic gramophone, a member is located directly in the path of the pick-up to restrict the inward movement of the latter' to a position where it is required to be lowered at the start of a record or stopped outside the edge of the record. In its simplest form, the invention may comprise a member 15, Fig. 2, projecting downwardly from a steadying arm 13 which normally rests on the uppermost record of a stack carried by a retractable step 6 on the centre-post 3. After the last record has been released on to the turntable 2, the arm 13 itself rests on the step 6 until the said last record has been played and at the next automatic operation the arm 13 is released by the step 6 so that the arm 13 drops to a position in which the member 15 intercepts the pick-up arm 5 which is subsequently lowered on to a rest 11 to operate a switch to stop the machine. In a second embodiment, Fig. 4, a pick-up rest 25 has an upright portion carrying two hook ended arms 26, 27, one or other of which may be manually swung over into a horizontal operative position for the purpose of restricting the inward movement of the pick-up arm 20 according to whether a smaller or larger sized record is to be played. In two other embodiments, two intercepting arms are employed which are made individually effective to intercept the pick-up arm, in accordance with the diameter of the record falling to the turntable. In the particular embodiment shown in Fig. 5, two arms 43, 44 are pivoted on a pin 47 and are brought into position over the pick-up arm 37 and rest on a ledge 51. The arms 43. 44 are in frictional engagement with each other, but are free to move about the pin 47. The arm 43 consists of two parts 43a, 43b pivoted together at 43c, and are maintained in alignment with each other by a spring rod 52, and such that in their normal position, as shown in Fig. 5, the hook end 45 is lower than the hook end 46 of the arm 44. When a record 39 of smaller size falls to the turntable 35, the pick-up arm 37 is therefore intercepted only by the hook end 46 of arm 43. When a record 40 of larger size falls to the turntable 35, the part 43a of the arm 43 is temporarily swung downwardly during which movement the arm 44 is moved downwardly on to the ledge 51 by a wire arm 56 mounted on the end of arm 43a. After the record has fallen the arm 43a returns to its normal position, leaving the end 46 of the arm 44 in a position to intercept the pick-up arm 37. During the return movement of the pick-up arm, the arm 44 is reset to the position shown in Fig. 5 by the contact of the pick-up arm with the sloping edge of the hook end 46 of the arm 44.
