In another modification a perforated cup 73 is provided on the lower end of the grid 30, its distance from the end of the anode vessel being made equal to that between the grid and the anode walls. The filament wires are suspended from two concentric rings 61, 62, the ends of the wires passing through holes in the rings and swaged into little balls. The cover 3 has a copper evacuating tube 80 which is sealed to a glass tube 81 which can easily be sealed after evacuation of the device. After assembly of the parts, the filament and grid are subjected to heat treatment, the metallic impurities being deposited on the cooler parts such as the anode, cover and leading-in members. The anode may then be replaced and the parts reassembled and evacuated.

Abstract: 976,686. Control systems for electrostatic precipitators. TUDOR A.B. June 6, 1963 [March 22, 1963], No. 22654/63. Heading H2H. [Also in Division G3] In an electrostatic precipitator, the frequency of flashovers is kept at a safe level and the formation of dangerous arcs is prevented by a control circuit which includes thyristors or controlled rectifiers and which is arranged to vary the magnetization current of a transductor in series with the A.C. supply to the precipitator. As shown, the ionisation chamber 4 of a precipitator is supplied from an A.C. source over a rectifier 3, a stepup transformer 2 and a transductor 1 which derives its magnetization current over a rectifier 7 and under the control of two thyristors 8. The firing angle of the thyristors is controlled by a pulse generator 9 responsive both to flashovers in the chamber 4, as detected by a transformer 6, an integrator 11 and an amplifier 10, and to excess current condition, resulting from the formation of an arc, as detected by a transformer 5 and the amplifier 10. The arrangement is such that the transductor 1 is automatically controlled to stabilize the operating conditions of the precipitator.

Abstract: 670,550. Wrapping. MAY & BAKER, Ltd. July 4, 1950 [Sept. 2, 1949], No. 22859/49. Class 94(i) A device for enclosing a carton in a wrapper of heat-sealable material comprises a wheeled carriage 12 guided by a slot 11 in a base 10 and reciprocable manually to an extent determined by an adjustable stop 26 on the base. The top 15 of the carriage forms a jig for the initial folding of the wrapper around the carton to form a tube with a longitudinal overlap and projecting ends, the wrapper being positioned by adjustable slides 16-18 and the carton by a well 21 and line 27. The front face of the carriage supports folding blades 28 and 29, the latter being spring mounted to compensate for slight variations in the length of the cartons, and houses a horizontal heater bar 14, see Fig. 5 (not shown), and its ,electrical connections. The partially-wrapped carton is first pressed towards the bar between the blades which form the first end folds and the bar then seals the overlapping portions of the wrapper to form a seam. The carriage is then moved to the left to carry the partially-wrapped carton into engagement with the ends 36 of spaced vertical plates 32 which are carried by the base and are formed with curved folding slots 38 and 40. Each plate carries a spring finger 42 which prevents retrogade movement of the carton when the carriage is returned to its initial position ready for the next carton. The ends 36 initiate the second end folds and are adapted to enter recesses in the blades 28, 29. The slots fold the upper and lower flaps thus formed downwardly and upwardly as the carton is pushed between the plates 32 by the delivering of further cartons by the carriage. The cartons pass.finally between heaters 43 which seal the end closures. The plates 32, heaters 43 and blades 28, 29 are adjustable towards and away from each other to deal with cartons of different lengths.

Abstract: 190,759. Sykes, A. F. Aug. 29, 1921. Addition to 160,223. Magnetic instruments.-Consists in the use in sound-recording apparatus of the kind claimed in the parent Specification, of an electromagnetic recording device having an armature of the reed or bar type, which armature is provided with stiffening fins or the equivalent, and has the engraving stylus directly attached thereto. Damping material, such as rubber, may be interposed between the armature and the stiffener, and, further, oil or other viscous liquid may be interposed between the magnet-poles and the armature. Figs. I and II (22860/21) show a construction in which the reed armature 120 of a Brown telephone receiver has attached thereto, or integral therewith, a stiffening extension 121, to which an engraving jewel 3 is secured. The magnet and windings are immersed in grease or the like, to suppress parasitic vibrations. The harmonics of the recorded sounds may be magnified by associating the recorder with compensating circuits in various ways. In the modification shown in Fig. III (22860/21), which is designed for making lateral-cut records, the stiffened armature 120 is mounted on a traversible block 122, so that the air-gap between the armature and the poles may be adjusted. The magnet may be duplicated and arranged so as to act differentially on the armature. The device shown in Fig. I (31027/21) comprises a Brown receiver, to the armature 120 of which is attached by a screw 132 a metal sheet 129, having soldered thereto a stiffener 130 which carries the stylus 3. A rubber pad 128 is inserted between the parts 120, 129. The screw may be omitted and the other parts cemented together. Fig. II (31027/21) shows a further modification. The armature 62 is attached to a lamina 133 which carries the stylus and which is pierced near one or both ends to form a number of resilient strips 134, the. apertures being preferably filled in with rubber. A slotted holder, to which the member 133 is clamped at its ends, carries a ball to determine the depth of cut in the wax. The holder is attached to the shell of the receiver. Specification 190,840 is referred to.

Abstract: 423,250. Printing-surfaces. ECONO PRODUCTS, Inc., 52, James Street, Rochester, New York, U.S.A.-(Assignees of Wilson, S. C.) Aug. 17, 1933, No. 22996. Convention date, Aug. 17, 1932. [Class 100 (ii)] Rubber or like printing-plates are formed from a matrix composed of a thermo-setting resin such as formaldehyde-phenol, formaldehyde-urea, formaldehyde-thiourea, or the like. Materials known under the Registered Trade Marks " Bakelite ", " Condensite ", or " Durez " may be used. The matrix is pressed against an original electrotype &c. under conditions of temperature, e.g. 300‹ F., and pressure that the resin is not completely cured during the moulding of the matrix. The rubber printing-plate is moulded from the matrix under similar conditions which prevent the conversion of the matrix to brittle form, so that a number of printing-plates can be produced from the same matrix. The rubber may be vulcanized during moulding. The matrix can be formed with a metallic backing during its formation by laying a thin perforated metal plate on the top of the resin during the moulding process, which causes the resin to bind into the perforations of the metallic backing plate, while the perforations permit free escape for gases. The backing plate may be formed of solid metal with a sheet of fabric arranged between the resin and the metal. The resin may be formed of a plurality of thin sheets, and to assist separation of the matrix from the original or the moulded plate a coating of a colloidal solution of graphite in water may be used.
