Title: Improvements in systems for justifying the spacing of printing characters
IPC: B41J19/64
Filed: 1945-05-01
Abstract: 621,023. Typewriters. HUEBNER, W. C. May 1, 1945, No. 10987. Convention date, May 3, 1944. [Class 100 (iv)] [Also in Group XX] A space regulating system for adjusting the length of step-by-step movement of a typewriter carriage includes a line of spaced stop elements normally arranged along the direction of movement of the carriage, a co-operating stop member movable with the carriage and engageable with the stop elements in succession to effect step-by-step movement of the carriage, and means for changing the angle between the line of stop elements and the direction of movement of the carriage for varying the lengths of the step movements. As shown applied to a photographic type-composing machine, the carriage C is moved by a shaft carrying pinions engaging fixed toothed racks, the shaft being turned either manually or through an electric motor geared thereto through slip or friction gearing. A rotatable disc 25 is adjustably mounted so that its axis 26 may be disposed in the vertical plane of the sensitive plate on the carriage C. A justification bar 32 formed of upper and lower sections and carrying spaced pins 33 is secured in a diametric channel on the top of disc 25. A stop bar 34 extending across the bottom of carriage C in a plane at right angles to the plane of the sensitive plate engages one after another of the pins 33 which are successively retracted to effect step-by-step movement of carriage C. The lower portions of the pins 33 extend through a lengthwise channel in the lower section of bar 32 between two flexible ribbons 36 under tension to hold the pins either in the projected or retracted position. A bar 37 on the carriage C can be moved downwardly against springs 38 to depress successively the pins 33 by means of rack-and-pinion mechanism operated from fluidpressure actuated mechanism as in Specification 621,025, [Group XX]. A pin-lifting bar 50 operated by similar rack-and-pinion and fluidpressure actuated mechanism may be raised by operation of a key on return of the carriage C to its initial position after recording of a line of characters. The distance that the carriage stop travels from engagement with one pin to engagement with the next decreases as the disc 25 is turned to set the justification bar 32 at an increasing angle to the direction of motion of the carriage C. The disc 25 may also be shifted bodily in the direction of travel of the carriage C to provide for the spacing of special characters which require more or less than the normal spacing. The justification bar may be replaced by another for use with a different range of character point sizes. Automatically controlled mechanism may be used whereby the operator can predetermine the required spacing of the characters and the length of the line of printing. Specification 621,022, [Group XX], is referred to.

Title: Improvements in four corner box staying machines
IPC: B31B3/46
Filed: 1929-04-15
Abstract: 325,741. Brodsky, G. April 15, 1929. Feeding webs.-Stay strips are applied simultameously to the four corners of a folded box by rod-operated pressing-elements actuated electrically, magnetically, or by fluid pressure. The stay strips are applied to the box corners by pressing-elements 11, Fig. 1, actuated by plungers 8 connected to the armatures of solenoids carried on brackets 5 connected diagonally in pairs by arms 2a, 3a rotatable about the vertical axis of the box form 13 so as to be adjustable for different sizes of box. The stay strips are fed from rolls 61 supported from the machine frame, and pass over moistening or gumming rolls 63 to feed-rolls 38, which are actuated to feed predetermined lengths of strip, and also to move the strip towards the box form during part of the stroke of the pressing-elements 11 by the following arrangement. As seen in Fig. 7, the plunger 8 connects by means of a tooth 71<a> with a spring tooth 70 carried by a slidable bracket 37 which supports the feed-roll 38 so that when the presser 11 moves to the left the feed-roll 38 is carried with it until a stud 73 contacts with the machine frame, when the spring tooth 70 disengages from the tooth 71<a>, the latter yielding downwards, so that the bracket 37 comes to rest. Simultaneously the feed-roll 38 is rotated to feed the desired length of strip by a cord 46 passing round and secured to a pulley 45 connected by a one-way clutch 57 to the feed-roll, the other end of the cord being secured at an adjustable point to an element 48 pivoted at 49 to the solenoid casing 6 and connected at 53 to the plunger 8 so as to be oscillated, the connection at 53 being automatically broken at substantially the same time that the bracket 37 comes to rest. The desired length of strip is thus fed forwards and is severed by the relative movement between the side of the bracket 37 and the presser 11, after the bracket 37 has come to rest, by a knife-plate 76 moving with the bracket 37. In a modified arrangement, sbown in Fig. 21, the stay strip is fed intermittently in predetermined lengths from a roll 149 over rollers 152, 145 by means of a plunger 133 of adjustable stroke, which connects at 138 with a belt that operates the roller 145 through a one-way clutch. Cutting of the strip is effected by a second plunger 131 actuated at the end of the stroke of the plunger 133, the strip being severed at a knife plate 158 as the presser 134 moves past it.

Abstract: 979,220. Cable terminations; sleeve couplings. BURNDY CORPORATION. March 26, 1963 [March 30,.1962], No. 11895/63. Heading H2E. A moisture-proof end seal or joint for a mineral-insulated cable 1 having a metal sheath 2 and inner conductors 3a, 3b, is made by passing conductors 3a, 3b through a compressible insulating insert 4 and a filler plug 5 located within a metal sleeve 6 so that the cable mineral insulation 1a and sheath 2 abut against insert 4, crimping one end of sleeve 6 to the sheath 2 and then crimping another portion of the sleeve 6 around the plug 5, when the latter expands rearwardly to compress the soft insert 4 against the cable end face. The soft insert 4 and plug 5 may be replaced by a single compressible plug (Fig. 8, not shown). The crimps are polygonal in cross-section, preferably hexagonal and adjacent crimps are offset to prevent tracking of moisture. The above seal may be used in cable terminations, when the metal sleeve may be closed at one end or may lead into electrical apparatus, or it may be used in cable jointing as in Fig. 11. In this embodiment, a sleeve 13 is crimped firstly over the sheaths 12, 42 of cables 30, 32 and then around neoprene inserts 14, 16 which are thus pressed against the cable ends and against central filler insulation 18, which may be magnesium oxide as in the cable insulation. The inner conductors are joined by indentation splicing sleeves 22, 24 covered by insulating sleeves 26, 28. Suitable materials for the soft compressible inserts are silicone rubber, asbestos or neoprene, and for the filler plugs are plastics such as nylon, tetrafluoroethylene, polyethylene or acrylic resin.
