Title: Improvements in push-button incremental tuners
Inventor: GANDERTON PETER CLIFTON
IPC: H03J5/12
Filed: 1961-03-09
Abstract: 940,439. Radio receiver push-button tuning mechanism. SYDNEY S. BIRD & SONS Ltd. Feb. 12, 1962 [March 9, 1961], No. 8704/61. Heading H3Q. In a push-button tuner a number of channels may be selected individually by means of preselectors of helical form, and mounted on the shaft of each push-button such that when one of the push-buttons is operated the angular setting of its helical preselector about the pushbutton shaft determines the position of a contact assembly along a track over a series of inductance elements and their associated fixed contacts. As shown in Fig. 1, helical preselectors 25 are mounted on shafts 17 of push-buttons 16 which are biased away from the tuner wall 12 by springs 23 and arranged to be rotatably and axially movable. When one of the buttons is pushed inwardly the helical preselector 25 comes into contact with abutment 26 on a rod 27, arranged to rotate about its longitudinal axis and connected by levers 28 and pins 29 to a contact assembly 13 slidable in slots 11, Fig. 3, such that the rod rotates and the contact assembly moves over the fixed contacts of a circuit board 14. Each shaft 17 is further provided with a flange 31 which when the pushbutton 16 is pushed inwardly forces down a bar 32 biased by spring 33 and passes over it, the bar 32 returning to its position and locking the shaft in its operating position. The shafts 17 are splined to toothed collars 21 which cooperate with three 120 degrees spaced projections in the holes through the tuner wall through which the shafts pass, whereby both the axial movement of the shaft 17 is limited and the final position of the preselector 25 and hence the contact assembly 13 may be determined by angularly rotating the shaft 17. Thus, once each preselector has been set to a predetermined angular displacement one of four channels may be obtained by pressing the appropriate button 16. One of the shafts, Fig. 1, has no preselector 25 and acts as a trip to release the push-buttons. The hollow shafts 17 are also provided with rods 42 which thread into the ends of inserts 40 and are arranged when the push-button is operated to engage a tongue 44 formed on a hinged plate 45 to cause a plunger attached to the plate to move axially in the direction of the shaft 17 and vary the capacitance of two trimmer capacitors. When the shaft is in its locked position the capacitances are varied by rotating the insert 40, thus causing the threaded rod 42 to move along the axis of the shaft and thereby alter the distance the rod protrudes from the shaft. In the embodiment of Fig. 3, the push-button on the extreme left has no helical preselector but is provided with a cylindrical abutment on its shaft which engages a projection 26 to move the contact assembly to the distance determined by the dimensions of the push-button. In addition this push-button carries a switching arm 33 of a switch, Figs. 4, 5 (not shown), and is operated whenever the tuner is required to select F.M. signals.

Title: Improvements in or relating to the reduction of zinc ores and other zinc-bearing materials
Inventor: QUINTIN ALBERT ANDRE JOSEPH
IPC: C22B19/18
Filed: 1959-03-16
Abstract: 863,786. Extraction furnaces. COMPAGNIE DES METAUX D'OVERPELTLOMMEL ET DE CORPHALIE. March 16, 1959, No. 8947/59. Class 82(1) A multiple retort furnace for the production of zinc has a series of condensers in which are obtained fractions of successively increasing purity with respect to materials having a higher boiling point than that of zinc. The first condenser is common to a number of retorts 1 (Fig. 1), one of its walls being formed by the front wall of the furnace, and a second wall 4 parallel to it consisting of refractory material in a steel frame, being removable to provide access to the furnace. Associated with wall 4 is a second panel 5 of heat insulating material, the distance between them being variable to control the amount of zinc collecting in the condenser. Vapour leaving the first condenser passes to a second condenser 11, the carryover of drops of impure zinc being avoided by subjecting the vapour to centrifugal action by device 7, whereby drops of liquid are flung against the wall 9, where they coalesce and flow into channel 6. Gas leaving condenser 11 passes through a similar centrifugal device 13 and then to a third condenser or to a cooling tower 16 where final traces of zinc are removed. The refractory material of wall 4 may consist of a mixture of coke or graphite with refractory clay or refractory cement, and may be rendered impervious to zinc vapour by coating with a glaze of borax with dextrin or organic glue and refractory clay. Wall 4 may also incorporate a sheet of refractory steel coated with mica or asbestos attached by sodium silicate. Construction of this wall is such that the metal frame is protected from direct exposure to radiation and to zinc vapour; the frame is hollow and cooled by the passage of air or high boiling liquid. A protective coating for all other surfaces in contact with the zinc and carbon monoxide which prevents the accretions of zinc oxide from adhering strongly consists of a carbonaceous material with organic glue. Specifications 594,487 and 667,312 are referred to.

[Class 96.] An apparatus for drying a continuous web of paper, cellulose pulp, &c. fed in a zig-zag path through a drying chamber includes a plurality of endless conveyers placed one above the other, each comprising endless parallel chains with transverse websupporting rods secured to the chains, and direction-reversing rollers round which the web passes from one conveyer to another, and which take up only forces longitudinally of the web. The conveyors are supported by rollers attached to the rods and running on rigid rails, and are driven through sprocket wheels. The reversing rollers may be coaxial with the sprocket wheels or may be mounted beyond the sprocket wheel, as shown in the Figure, in which case a bridge 24 is provided to convey the web 6 from sprocket wheels 3 to rollers 7, and the wheels 3 and the adjacent roller 7 should be mounted on a common carriage so that both may be moved in adjusting the tension of the conveyer. The guide rollers may be driven wholly or partly by the web ; for example, the axle of a guide roller may be put into driving connection with the axle of a sprocket wheel by a friction clutch during the threading of a paper web through the machine, and when the web itself can keep the roller running the clutch is opened. Screens parallel to and between the runs of the conveyer direct the drying fluid along the conveying track.

Abstract: 560,026. Making wire spokes. MELTON, E. July 3, 1942, No. 9188. [Classes 83 (ii) and 83 (iv)] Angular bending; shearing.-A tool for forming headless wire spokes of the kind having a double bend at one or both ends, such as. are described in Specification 486,772, (Group XXXIV], comprises a block on which are mounted a plunger and an adjustable measuring device, the plunger and block having co-operating working faces for cutting a spoke to length and for shaping it to the required double bend. In one form the block 1, which is secured by screws to a bench contains a passage.for a plunger 10 and for a, measuring rod 3 with a flat graduated face and and end flange 6 and held in adjusted position by a screw 5 and-brass pad 4. The block is also provided with an opening 9 and the plunger which has a stop collar 12 and retracting spring 13, has a pin 14 guided in a slot 15 in the block. The block is furnished with two passages 16, 17 for the wire. The wire is first passed through the hole 16 and through a hole 18 in the plunger and with one endin a recess 7 in the flange of the measuring rod. The head 11 is struck by a hammer so that the plunger co-operates with the block to shear the wire to desired length. The wire is then passed through passage 17 with one end against the face of the flange 6 and a double bend is formed by co-operation of the shaped end of the plunger with the block. In a form in which the shearing and bending are effected in a single operation the flange 6 need not be recessed, and the hole 9 is placed slightly higher than in the previous forms and the lower end thereof serves to support the wire which is pushed through a hole 19 in the block. In this case when the plunger is forced down the outer side co-operates with the bottom to the hole 9 to cut the wire to length and the inner side and end effect the bending as in the previous form. In order to remove the plunger the guide pin 14 is brought opposite the upper hole in the block and then driven out.
