Title: Improvements in machines for inserting sheet material into envelopes
IPC: B43M3/04
Filed: 1955-08-31
Abstract: 779,971. Inserting sheet material into envelopes. BOUGHTON, F. E. Aug. 31, 1955 Oct. 11, 1954], No. 25033/55. Class 94(1). In a machine for inserting sheets into envelopes, the envelopes 32 are fed in succession from a magazine 24 by a pair of intermittently rotated rollers 60 and conveyed over the surface of a table 22 by pairs of rollers 46, 47 and 48 which are driven continuously and co-operate with pairs of adjustable spring-loaded rollers 49, 50 and 51 projecting through openings in the table. The flap of each envelope is folded back by a pivoted counterweighted wedge 70. The rollers 48, 51 feed each envelope beneath a spring guide 78 to a pair of rollers 80 located above gaps in the table in which are positioned blocks 85 carried by a spring-loaded adjustable bar 81, each block being formed with an opening 36 through which passes a leaf 87 secured to the bar. The rollers 80 co-operate with the springs 87 to feed the envelope over an adjustable projection 90 and beneath a spring 92 and a continuously-driven roller 94 mounted over a gap 97 in the table 22, the envelope being finally arrested by stops 110 projectible through slots in the table by camoperated arms 111. The projection 90 and spring 92 co-operate to open the envelope for the reception of an insert 33 which is fed from a magazine 25 by intermittently-rotated rollers 132 and 133, 134 and passes over guide springs 150 which hold down the flap of the envelope and then under the rollers 80. The stops 110 are then withdrawn and a roller 95 on a camoperated arm 98 is elevated to press the filled envelope against the roller 94 so that it is fed to the nip of discharge rollers 120, 121. The springs 87 normally maintain the envelope in light frictional engagement with the rollers 80, but yield when the envelope is arrested by the stops. This allows the envelope to bulge into the openings 86 and prevents buckling thereof due to the continued feeding action of the rollers.

Title: Improvements in and relating to the Measurement of Alternating Electric Current Power.
IPC: G01R11/52
Filed: 1918-12-21
Abstract: 136,515. Ferranti, S. Z. de, Wall, G., and Ferranti, Ltd. Dec. 21, 1918. Induction motor meters; power meters; registering special quantities; testing. -A power or energy meter of the induction type is adapted to measure the wattless component of the power or energy in a singlephas.e circuit. Two driving- elements are employed giving equal and opposite torques on non-inductive loads. The series windings g and shunt windings f are wound on their usual cores as for measuring true power or energy, but the lag of the shunt flux is different in the two elements. One shunt flux may lag by 90 degrees and the other by 45 degrees, in which case true power or energy may be read by disconnecting one shunt circuit f by a switch m. The volt-amperes and power-factor may thus be estimated. Equality of the driving-elements is effected by adjusting the gap in one of the shunt magnets or varying the position of a magnetic shunt, or by adjusting the working gap between the series and shunt magnets. The full-load speed is adjusted by moving either or both of the retarding permanent magnets towards or away from the spindle.

Patent GB-490268-A (GB)
Title: Envelope making machine
IPC: B31B19/00
Filed: 1937-09-27
Abstract: 490,268. Making envelopes. GRAY, R. L. Sept. 27, 1937, No. 26173. Convention date, Feb. 17. [Class 94 (ii)] In a machine for making window envelopes &c., a substantially trans parent patch being pressed on to a blank and attached thereto by a thermoplastic adhesive 'activated through a heating and pressing device, the blank or the patch being moved through an activating path before the final sealing pressure is applied, the length of the activating path exceeds the width of an envelope in order to ensure reliable assembly in speedy mass production. Envelope blanks E, with windowapertures cut out, are stacked at 12 and removed therefrom by a vertically reciprocable gummed picker, the members 14, 16 thereof gumming the sealing flap and back flap of the blank respectively. The members 14, 16 are gummed by horizontally reciprocable rollers 24 and the blanks are removed from the members 14, 16 by a stripper plate 26 to position the same on to a pusher 28 which, in turn, moves to position the blanks over a folding well 32. Patch-forming material 38 from a reel 36, carrying a coating film of thermoplastic material on its under surface, is fed between cutters 40, 42, an oscillatable suction carrier 44, with a suction surface 50, moving to convey a cut-off patch to the under surface of a spring-biassed suction head 62. The suction to the carrier 44 and the head 62 is automatically controlled by a valve 52, operated by a cam 54, from a source of suction 51. In descending, the head 62, heated by electric elements positioned therein, carries the patch and the envelope blank downwardly into the folding well 32 where a shaped rubber seating in the bed-plate 92 takes the resilient pressure of the heated head 62 to seal the patch in position. The bed 92 is held horizontally by a rod 146, governed by a cam 156, which periodically moves to allow the bed to tilt about its pivot pin 143, an air jet 206, directed against the partly folded sealing flap F, moving the folded blank past a guide 220 to the grip of members 222 on a drying conveyer 218. The air jet 206 is governed by a cam-operated valve 202 fed from a supply 194. Horizontally-movable spring-urged retaining pins, in the bed 92, move to engage grooves in vertical pins, when the spring-biassed bed is in its lowermost position, to increase the time of sealing pressure on the patch. A spring-biassed bar 170 contacts, in the bottom position, with the roller 168 to move other vertical pins to release the blank from surface adhesion to the rubber seating of the bed 92, the same movement releasing the jet 206 to blow air for the removal of the folded blank. Angle members 192 contact with the head 130 to release the horizontally spring-urged retaining pins previously referred to. The suction to the head 62 is released, at the bottom position, by a valve 140 governed by a cam 142. Specifications 409,274 and 409,307 are referred to.

Title: Improvements in power operated winding mechanism
IPC: G03B19/04
Filed: 1952-10-20
Abstract: 723,494. Spring motors. FRYE, J. Oct. 20, 1952. No. 26268/52. Class 10. A spring motor comprises a frame, a rotor journalled therein, a leaf-spring attached between said rotor and frame, manual means for turning the rotor in one direction to tension said spring, a frictional brake unidirectionally engaging the rotor in the direction opposite to that for tensioning the spring, means for releasing the brake, a centrifugal governor limiting the rate of the spring-driven movement of the rotor, and stop-means of the threaded spindle and disc type for limiting the total number of revolutions of the rotor in both directions of rotation. As shown, the spring motor is adapted to effect rewinding of a roll film after camera exposure as described in Specification 717,910, [Group XX], and comprises a spring 51 fixed to the body at 52 and to a rotatable shell or rotor 54 having a key 90 engaging in a key slot in the supply cassette spool, rewinding of the film into the cassette being normally prevented by a spring brake 60 gripping the shell 54 and opposing its anticlockwise rotation, spring 60 being more powerful than spring 51. The spring 51 may be tensioned either by the manually-operated unwinding of the film rotating the supply cassette spool and hence the shell 54 or by means of a knob 94 on an axially-movable spindle 93 having a key engageable in a recess 91 in the shell 54. Prior to feeding the film, a slide 43 may be moved freely against its spring 46, but once the first film frame is fed, an eccentric 55 on the spring 51 allows an anti-clockwise urged lever 57 to move a bolt 58 behind a lug 59 on the slide to restrict its movement to the right. Moving the slide to the right then only releases the brake 60 which is connected at one end to a bar 61 carried by the slide, whereupon the spring 51 rewinds the film into the supply cassette, the speed of rewinding being controlled by a centrifugal governor comprising pivoted pawls 83 on the shell 54 engaging the inside of a fixed drum 82. When the film has been rewound, the spring 51 returns to the position shown so that its eccentric rotates the lever 57 to withdraw the bolt 58 allowing the slide to be moved fully to the right to open the camera by cam 41 depressing the extension 40 on the latch 36. The total movement of the film and the tensioning and unwinding of the spring 51 are limited by a disc 86 having two notches engaged by keys 88 on the inside of the shell being movable as a nut along a fixed threaded pin between two fixed discs 89.
