Title: Improvement in circular rib knitting machine and method of operating same
IPC: D04B9/06
Filed: 1939-12-21
Abstract: 534,058. Knitting-machines. SCOTT & WILLIAMS, Inc. Dec. 21, 1939, No. 32685. Convention date, April 11, 1939. [Class 74 (ii)] A circular rib machine having two-part dial needles, a, b is provided with means for passing all the dial needles through transfer operations while varying the movement of some of the castelements b to prevent effective transfer on those needles. In addition to the usual transfer cams 16, 17 for ejecting and retracting the needle hooks, as e.g., described in Specification 196,124, [Class 74 (ii)], two fixed cams 18, 19 and a movable cam 20 are provided. The cam 18 holds the hooks a in their retracted position until the cam 16 ejects them, and the cam 20 is arranged on the outer side of the cam 18 so as to eject the desired cast-off elements b at a point in advance of the ejecting of the hooks a, and to a position as shown in Fig. 2 in which the transfer points n<SP>20</SP> of the elements b are radially outside the portion n<SP>6</SP> of the hooks a. The cam 20 delivers the butts n<SP>16</SP> of the cast-off elements to the cam 19 which holds them in the outward position until they engage the usual cam 17. The result is that when the hooks a are ejected to transfer position by the cam 16, the point n<SP>20</SP> cannot engage the loop held by the hook a and transfer cannot take place. The cam 20 in its operative position may engage only the high operating butts n<SP>16</SP> of a hosiery machine so that the transfer on the instep dial needles is prevented when transferring loops from the heel dial needles to the cylinder needles. Specification 197,665, [Class 74 (ii)], also is referred to.

Title: Automatic telecommunication exchange
IPC: H04Q3/00
Filed: 1966-07-22
Abstract: 1,111,470. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 22 July, 1966 [27 July, 1965], No. 33050/66. Heading H4K. In a PBX final selector in which the lines to a PBX are distributed over different sections of the selector, a call to a PBX utilizes the line in the section carrying the least amount of traffic. As shown, each individual line, in all of the sections T1 to Tg at the outlets of switching network 1, is provided with a resistance 10 or 13 which is connected in series with a common resistor 12 for its section when it is taken into use. When control circuit 2 determines that a PBX call is involved, it causes scanner 4 to set successively to each section having a line to the PBX. The potentials-which are indicative of the traffic in a section-on resistors 12 are processed in such a way that store 7 always contains the identity of that section which contains a free line to the PBX and which is under the lightest traffic load. When all, or at least a predetermined number, of sections have been interrogated the currently stored identity is passed to control so that the call may be completed. Suitable logic circuitry for performing the above operations is depicted in Fig. 2 (not shown). As an alternative, or else in addition, a " memory map " of the current state of the system may be used for determining the traffic load and/or the identities of free PBX lines.

Title: Separating gases from liquids
IPC: B01D19/00
Filed: 1961-09-15
Abstract: Apparatus for separating gases and vapours from fuel oil comprises an oil reservoir 12, a device with heater 16 and oil burner 18 which heats oil delivered thereto but burns only a part of said oil, gas separating means 20 interposed between said reservoir and said device for removing entrained gases from the fuel oil, vapour separating means 36 for removing vapours from excess fuel oil discharged by the burner, and means 38 for returning said excess fuel oil to the burner in admixture with fuel oil from gas separating means 20.  As shown in Fig. 1, to which the above numerals refer, fuel oil is drawn from reservoir 12 through preheater 62, line 60 and pump 24 and delivered to column 50 at inlet 64.  Oil flows downwardly through column 50 and is degassed therein; thereafter passing by pump 28 and line 66 to heater 16 <PICT:0932329/III/1> and burner 18.  The capacity of pump 24 is greater than that of pump 28 so that excess oil is introduced into column 50, said excess being returned by line 32.  The capacity of pump 28 exceeds that of burner 18, excess fuel oil flowing through line 70 to vapour separator column 54 where vapour, foam and entrained gas are liberated and pass upwards, oil passing downwards to be recycled through line 66.  The vapour-foam stream is constricted in passing through orifice 74 and the foam is thereby largely liquefied.  The vapour is sufficiently cooled in the upper portions of chambers 50 and 54 so that the fluid mixture returns to reservoir 12 at a temperature below the flash temperature of the oil therein.  Gases, vapours, reduced foam and excess oil are returned to reservoir 12 by line 78 with pressure-relief valve 44.
