Title: Improvements in or relating to tag affixing machines
IPC: D06F93/00
Filed: 1963-02-12
Abstract: 978,619. Stapling machines. P. N. BRAUN. Feb. 12, 1963 [Feb. 13, 1962], No. 5487/63. Heading B4C. [Also in Division B8] A machine for affixing indentification tags to garments, such as in laundry plants, comprises a frame 32, 33 having a garment supporting arm 34 movable to an operative position in which a tag is stapled to the garment, the tag being severed from a strip 90 of similar tags during the operative movement of the arm by means of a shear device having a guide 100 and a blade 110 co-operable with a shear block 97 in which a recess 104 forms a continuation of the guide. The arm 34 is pivoted at 35 on the frame and is provided with pins 50 which are adapted, when the arm is moved to the operative position shown in Fig. 5, to engage faces 51 formed on links 52. The links 52 are connected to levers 54 which transmit their movement to a lever assembly 56, 60, 62, 64, the lever 64 being coupled to a link 74 secured to the armature of a solenoid 72. The link 74 is moved upwardly so that a roller 65 thereon engages a lever 67 and thereby actuates a switch to energize the solenoid; the lever assembly then rotates about a pivot 57 so as to cause pins 55 on the lever 56 to engage a staple driver 111  and thereby drive a staple through the tag and garment, the ends of the staple being clenched over on a anvil 37 on the arm 34. During the stapling operation, the pins 55 also engage the shear blade 110 so that, in co-operation with the shear block 97, the lowermost tag is severed from the strip 90; the blade is returned to its normal position by means of a pawl 120 actuated via a lever 122 connected by a link 125 to the arm 34. In the modification shown in Figs. 10 and 12, the blade 110 is mounted in a shear block 180 which is movable between plates 167, 163. The blade is provided with a V-shaped recess co-operating with a correspondingly-shaped projection formed in the shear block, so that in addition to the blade severing the tag from the strip, a notch may also be cut from one edge of the tag. The degree of movement of the shear block 180 is indicated by a graduated scale 224, Fig. 19, the block being manually moved by a lever 220 so that a notch may be cut opposite a number printed on the tag corresponding to the number selected on the scale. A second tag may be stapled to the garment in addition to the tag severed from the strip, the second tag being inserted individually into a holder 240 so that the same staple passes through both tags. In a further modification, the solenoid-actuated mechanism for the staple driver and shear blade may be dispensed with, the latter members being actuated by the manual pressure exerted on the arm 34. The tag strip is torn from the top sheet of a book of sheets clipped to a support table 260 on the machine. Each sheet may be of a different coloured paper and printed with indicia as shown in Fig. 16, the sheets being interleaved and joined at the top 20. Specification 745,608 is referred to.

Title: Improvements in telephone systems adapted for using loud speakers and normal receivers
IPC: H04M1/60
Filed: 1945-03-08
Abstract: 602,333. Substation equipment. AUTOPHON AKT.-GES. March 8, 1945, No. 5808. Convention date, Dec. 10, 1942. [Class 40 (iv)] A substation provided with a loud-speaker which is also used as a microphone comprises in addition a normal telephone receiver whose hook-switch besides providing for changing over from loud-speaker to normal telephone reception connects up the loud-speaker as a microphone. The arrangement finds particular use in enabling subscribers to break in during conference calls. In the calling sub-station, relay E, which energizes the amplifier V, is initially operated over the off-normal contacts k of the dial by - ve D.C., received over the phantom from the exchange, to which it subsequently locks. In the called substation, E operates to an initial A.C. pulse from the exchange and locks to subsequent D.C. Relay U is normally operated by the above D.C. to connect the amplifier V as a receiver. Removal of receiver T from the switch hook operates TK to disconnect U, whereupon the amplifier is connected as a transmitter. The calling subscriber may also break in by operating the dial so that its off-normal contacts k then shortcircuit U. The conference is called by dialling a special digit which on setting a connector, Fig. 2 (not shown), operates a relay over the third wire to common and busy all conference subscribers and a further relay is operated over the same circuit to transmit the A.C. pulse followed by the - ve D.C. to the sub-stations.

Title: Electromagnetic energy regulator for electric radiant heating apparatus
IPC: H05B1/02
Filed: 1953-03-02
Abstract: 756,338. Electromagnetic interrupters. PARSONAGE. S. H. Feb. 26, 1954 [March 2. 1953], No. 5809/53. Class 38(5) An energy regulator for a heater 13 comprises a mercury switch 1 mounted in a carrier 2 pivotally supported at 3 on a base 8, the free end of the carrier being supported by a spring 12 and carrying an armature 4 attracted by a solenoid 5 mounted on the base. The spring 12 is connected to an arm 16 pivotally mounted at 17 on the base and adjustable through an angle A whereupon it is clamped in the adjusted position. The base 8 is adjustable through an angle B about a pivot 9 by a manually operable cam 11 pivoted at 19 and co-operating with a roller 18 on the base. In one extreme position of the base 8, shown, the mercury permanently connects the switch contacts 6, 7 whereby the coil 5 remains short-circuited and the heater 13 is continually energized. In the other extreme position of the base, to which it is moved by clockwise rotation of the cam 11, the contacts 6, 7 are permanently open and the heater remains de-energized; also, a normally closed switch 14 is opened by a mechanical connection with the base 8 or cam 11 to de-energize the coil 5. However, angle B between the two extremities of the switch 1 is oscillated by successive energization and short-circuiting of the coil 5 to intermittently energize the heater 13 and give a variable control. At a high setting of the cam the oscillation frequency is low and the make periods of the contacts 6, 7 are long, whereas for a low cam setting the frequency is high and the make contact periods are short. The spring 12 causes a bouncing action of the switch 1 when it is oscillated. A counterweight 15 is preferably fitted on the carrier 2, and for a 3-phase load the latter may carry three switches 1. For the control of a heavy load a number of carriers and their individual operating solenoids may be mounted on a common base 8.

A fluid flow-meter 4 comprises a heater winding A and a resistance winding B together forming a measuring member 1 around and through which the fluid flows, and a reference coil C wound around the flow tube 5 and connected in a bridge circuit with resistance B to provide ambient temperature compensation so that bridge unbalance produces from amplifier V 2  a current which is fed to heater winding A to increase the temperature and thus the resistance of winding B whereby the bridge is rebalanced, the current to the heater serving as a measure of fluid-flow, a measure of which is obtained from amplifier V 3 . Heat loss to the tube wall from the measuring member is minimized by a compensating coil D which is maintained at the same temperature as the surface of the measuring member. The resistance winding B comprises, Fig. 2 (not shown) coaxial coils (8, 10) between which the heater winding (9) is coaxially interposed. It is stated that the bridge is arranged to be unbalanced for zero flow-rate so as to maintain a flow of current through the heater winding. In alternative embodiments there may be more than one heater winding and only one resistance coil, or the reference coil may be internal of the flow tube. The surface of the measuring member may be coated with nickel.

Title: Method and apparatus for separating gases or vapours from mixtures thereof
IPC: G01N25/14
Filed: 1946-02-28
Abstract: <PICT:0621897/III/1> <PICT:0621897/III/2> Mixtures of gases or vapours are separated by passing them into one end of an elongated container of adsorbent material, applying heat progressively from one end to the other to expel the individual gases or vapours successively from the adsorbent material; the expelled gases are replaced with mercury vapour to prevent their re-adsorption.  A suitable apparatus Fig. 1, consists of a column 1 of progressively decreasing cross-section charged with, say, activated coconut shell charcoal and which may be initially filled with hydrogen through pipe 11. Hydrocarbon-containing gases, say, are then introduced through line 6k until the column is filled, as indicated by a change in thermal conductivity, measured by cell 18, in the effluent gases. A sample may be drawn off through byepass 7 to indicate when the heavier components have reached that point.  Heater 5 is then energized to distill off the gases.  As the distillation proceeds, the heater is raised, and simultaneously a mercury reservoir 6, to cause the mercury to rise in the column.  The gases, of increasing heaviness, pass through a condenser 13, a collector 12 being provided for the measurement of any condensate, and through a capillary tube 14 which bridges a manometer 16.  The latter, Fig. 4, comprises two arms 14, 19, the arm 19 being connected to the high pressure side of the capillary.  When the flow of gas exceeds a predetermined amount, the water in arm 14 contacts a terminal 71 to energize a relay 59a, cutting out a motor 6h which elevates a platform carrying the heater and mercury reservoir.  If the gas flow still continues to increase, the water contacts a second terminal 72 which through relay 59, de-energizes the heater 5.  A bellows adjustment 16h is provided, but major variations are effected by changing the size of the capillary. After passage through a temperature equalizing coil 20, the volume of the gases is measured in meter 17, changes in the composition being indicated by the thermal conductivity cell 18.  A connection 22a is provided for the collection of isolated fractions when desired.
