Title: Improved method or process and means for separating or cleaning intermixed divided materials
IPC: B03B4/02
Filed: 1927-10-13
Abstract: 307,978. Davis, K. Oct. 13, 1927. Divided on 292,179. Pneumatic separating. - In apparatus for separating intermixed divided materials according to density of the type comprising a separating table which is pervious to air and on which the materials are simultaneously subjected to the vibrating action of the table and the upward pressure of air, the air perviousness of the table is varied over its surface in such a manner that the lifting power of the air decreases in the direction of movement of both the heavier and the lighter materials. The invention is described as applied to a table of the shape shown in Fig. 1, comprising inwardly and forwardly inclined separa.- ting partitions 20 leaving an unobstructed central passage 21 for the movement of the heaviest material, such as stone when the apparatus is used for cleaning coal. The table is divided into zones A - - D, which are shaped so as to conform generally to the direction or position of the separating partitions, and in which the lifting power of the air decreases successively by diminishing either the number or size of the perforations. Preferably in the neighbourhood of the discharge 41 for the heavy materials, the air pressure is increased as indicated at B, C, and the zones are arranged symmetrically at opposite sides of the central line of the table. In the construction of apparatus described, the forward discharge end of the table consists of a passage 30, Fig. 4, with air pervious sides, top and bottom and enclosed in a casing 39 the forward end of which has a discharge opening controlled by a pivoted and weighted gate 41. The outside separating partitions 13, 14 are preferably increased in height in a forward direction as shown at 13a, 14<a>. As shown in Fig. 5, the table is supported from the air chamber by pivoted arms 50, 51. It is moved in one direction by the snail cam 59 and returned by springs 54, stops 55, 56 being provided to produce a jarring impact at the end of the return movement.

Abstract: 1382862 Equalizer setting derivation SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 30 March 1972 [11 June 1971] 15204/72 Heading H4R In a device for indicating the adjustments required to the equalizers for a wideband telecommunications system which has at least one corrector acting over the whole frequency range of the system together with a number of other correctors, called bell correctors, acting on overlapping parts of the frequency range of the system, the differences from nominal level of a number of pilot signals received over the system are fed to respective storage positions 1, which feed a simulator P/V in which, for the adjustment of a parabolic or slope corrector acting over the whole frequency range, the simulator provides an error signal output to indicator N, which is reduced to a minimum by adjustment of the simulator setting, after which the setting is incorporated in the equalizer. The new valves of difference from nominal level of the pilots are again transferred to the storage devices 1 and the simulator replaced by a computer C which is switched to derive, in turn, the optimum settings for "bell" equalizers at various frequencies across the frequency range of the system, which settings, on indicator N, are transferred manually to the equalizer controls. The simulator, Fig. 3 (not shown), comprises adding networks (#) in which the outputs from stores (I) are combined with the simluated effect of the equalizer adjustment at the appropriate frequency (as derived in CW), the store outputs being averaged in groups of three, and combined in the summing networks (# 1  to # 4 ) with a  signal representing the average effect of the equalizer adjustment on those three, and the output of the summing network is combined (in summer #) with the outputs of further summing networks after full wave rectification (in M 1  to M 4 ). The final summer output is displayed (on N) and the equalizer correction adjustment (CW) varied to reduce the output (on N) to a minimum. The computer, Fig. 4, (not shown), comprises a resistive matrix (R 1 , 1 , to R 12 , 12 ), connected between the storage units (I 1  to I 12 ) and a switch connecting selected matrix outputs to an adder (#<SP>1</SP>) and indicator (N). The matrix is an inverse of the effects of equalizer adjustment on the pilot signal levels and thus the output on the indicator (N) provides an indication of the required equalizer adjustment to provide the appropriate equalization of the equalizer selected by the switch.

Title: Improvements in or relating to buttonhole sewing machines
IPC: D05B3/06
Filed: 1949-06-08
Abstract: 659,655. Buttonhole sewing-machines. NOYES, R. C. (Reece Corporation). June 8, 1949, No. 15273. [Class 112] Means are provided for changing the length of feed for the sewing of the second side of a buttonhole so that the numbers of stitches in the two sides may differ, means may also be provided for varying the distance between the stitches round the eyelet end of the buttonhole. In the machine described both means are actuated by the turret-rotating mechanism, to vary the lengths of the steps of movement of the feed cam, the latter means being controlled by hand. The feed cam is rotated by a worm driven through a oneway clutch 51 by a cam-oscillated link 46 connected to a pivot-pin 53 which is carried by a block 47 slidable along a crank-arm 48 on the driving member of the clutch, to vary the effective length of the crank-arm and thus the amplitude of its oscillation; the pin 53 is engaged by a slotted link 63 clamped to a pivot pin 62 mounted in an arm 60 which is pivoted at 61 and spring- biassed to the right and which is engaged by a slotted link 82 connected to a sliding bar 79 and by a stop 96, Fig. 11, on a sliding bar 95, so that these two members determine the position of the pin 53 on the arm 48, initial adjustment being effected by adjusting the pin 62 along the link 63. The cam-actuated turret-rotating lever 34, connected by a link 33 with an arm on the turret sector shaft, carries a cam 66, pivoted to it at 65 and adjusted on this pivot by stop screws 70, which has a track 67 engaged by a pin 71 on a crank 72; this crank is connected to a second crank 76 linked at 78 to the sliding bar 79, so that as the lever 34 rocks to rotate the turrets round the eye end of the buttonhole the bar 79 is moved to the right, remains there for a time, and is then brought back to a new position. A hand lever 88, Fig. 11, pivoted at 87 and carrying a spring catch 91 for engagement with adjustable blocks such as 100 near the ends of a quadrant 93, is connected by a link 94 with the sliding bar 95 so that the stop 96 can be placed in two adjustable positions, corresponding to the positions of the blocks 100, so that it can be readily set for sowing buttonhole eyes of two different sizes or an eyed and a straight buttonhole. In operation, the spacing of stitches along the first side of the buttonhole is determined by the position of one end of the cam track 67 relative to the pivot 73 of the crank 72, the spacing round the end of the hole by the hand-lever 88 (since during this part of the stitching the cam 67 moves the bar 79 to the right so that the arm 60 no longer lies at one end of the link 82), and that along the other side by the position of the other end of the cam-track 67.

A stationary electric induction device, such as an autotrans. former, has a first and a second winding section, the first winding section 1-3 having a terminal 3 physically adjacent a terminal 4 of the second winding section 4-6, the two sections being connected by a conductor between an intermediate point 2 on the first section and the terminal 4 of the second section, a protective arrangement comprising a resistor R having a negative resistancevoltage characteristic being connected between the terminal 3 and an intermediate point 5 on the second section, the point 5 being so positioned that the potential difference between 2-3 is normally substantially equal to that between 4-5. Any excessive potential difference between the terminals 3, 4 due to an abnormal condition, such as a stroke of lightning hitting a line connected to the terminal 1, is thus prevented since the resistance of the element R would fall to provide a low resistance path between the points 3, 5. Specification 292,110, [Class 38 (ii)], is referred to.

Abstract: 1,086,836. Photo-electric flame monitoring. BAILEY METER CO. April 6, 1966 [April 6, 1965], No. 15375/66. Heading G1A. [Also in Division G2] A flame detecting apparatus comprises a long tube which has at the end near the flame means to reflect radiation from the flame down the tube on to a radiation detector positioned at the other end of the tube remote from the flame. In Fig.2 the inner tube 30 of the three tubes 28 to 30 acts as a light guide for radiation reflected off the angled plane mirrors 48 to direct light through the lens 40 on to an ionization tube 26 sensitive to U.V. light. Air is blown between the inner and middle tubes which on escaping at the flame end is directed on to a protective quartz screen 38 to keep it clean. The outer tube 28 is a fixed mounting tube and permits partial rotation of the middle and inner tubes to align the mirrors 48 with the flame radiation. In Fig.2 the mirrors are shown fixed at various angles to the longitudinal axis of the tubes, which angles determine the field of view of the detector. Instead of being permanently fixed the mirrors may be individually adjusted, Fig. 8 (not shown), or may be replaced by internally reflecting prisms Fig. 6 (not shown). To enable radiation to be reflected down the tube which arrives at the tube end in a direction more at right angles to the tube axis than is shown in Fig. 2, the end of the tubes may be cut obliquely, Fig. 5 (not shown). When the end of the tube directly faces the incident radiation plane mirrors may be arranged symmetrically on either side of the tube axis, Fig.7 (not shown) or tubular conical mirrors, one inside the other, may be used, Fig.9 (not shown).
