Title: Method for use in the production of a copy of an original text and an apparatus for use in performing the same
IPC: B41M5/04
Filed: 1961-05-05
Abstract: 924,351. Copying methods and apparatus. W. RITZERFELD, and G. RITZERFELD. May 5, 1961 [May 25, 1960], No. 16361/61. Class 98 (1). A method for use in the production of a copy of an original text comprises the steps of photographically exposing to the original text a sheet having a light-sensitive silver halide emulsion, developing the sheet in a tanning developer, drying or partly drying the developed sheet, placing the emulsion side of the developed sheet into contact with the layer side of a hectographic-ink transfer sheet, and subjecting the sheets to an infra-red irradiation, the imageareas of the developed sheet being infra-red absorbing by virtue of the separated silver therein, the layer of the transfer sheet being caused by the infra-red irradiation to melt at regions thereof which contact the image-areas of the developed sheet and adhere to the said developed sheet at the said areas. In a modification of this method the hectographic inktransfer sheet has superimposed on its transfer layer a layer comprising a thermoplastic synthetic resin, said resin having a melting point below that of the -ransfer layer. Apparatus for use in performing the above methods is shown in Fig. 1. An exposed photographic sheet 46 placed in a tray 7 is fed through a tank 5 of tanning developer 6 by pairs of driven rollers 24, 25, 26, and 27 and by guides 15 and 16. The developed sheet is then substantially dried as it passes between a heated drying plate 17 and a guide plate 18, engages with a turnedover end 48 of a transfer sheet 47 lying on a table 8 and moves in superposition therewith between driven rollers 28, 29. The contacting sheets are exposed to I-R radiation by lamps 23 as they pass between a transparent guide table 19 and a white reflection plate 20, are pressed firmly together as they pass between driven pressure rollers 30, 31 and are then ejected from the apparatus housing 4 on to a delivery table 9. Lamps 23 are cooled by a fan 14 and the apparatus includes light shades 21, 22. In a modification (Fig. 2), not shown, the layers 23, plates 19 and 20 and rollers 29, 31 are replaced by a roller with axially arranged lamp acting simultaneously as a feed and pressure roller and as an infra-red lamp.

Filed: 1965-04-20
Abstract: 1,059,244. Capacitors. ILLINOIS TOOL WORKS Inc. April 20, 1965 [April 21, 1964], No. 16570/65. Heading H1M. A cylindrical wound capacitor 20 of foils of e.g. aluminium or metallized dielectric wound with intervening dielectric in a staggered arrangement is compressed to flattened form and provided with leads 24, 26 disposed radially of the winding axis 22, and embedded in the end portions of the capacitor formed by the overlapping edges of the dielectric material; the leads being retained by ribs formed by heat and pressure and compressed into contact with the respective turns of the electrode foils or coatings. The leads may traverse the longer (Fig. 1) or the shorter (Fig. 6, not shown) dimension of the capacitor end surfaces, and emerge in opposite directions in a plane transverse to the winding axis; the short lead 24 being bent parallel to the axis at 36 and the long lead 26 being bent to lie obliquely to the axis in either sense; the ends of the leads being insertable and solderable in holes of a printed circuit board so as to impose a stress on the connection by deflection of the long lead inwardly or outwardly relative to the axis (Figs. 2, 3, not shown). The stress in the long lead urges the portion 30 thereof embedded in the outer end of the capacitor into firmer contact with the appropriate electrode layers particularly in temperature conditions affecting the plasticity of the dielectric. The capacitor end surface 29 sits flush on the printed surface board (Figs. 2, 3, not shown) and no part of the leads extends axially beyond the capacitor end surfaces save for the bent legs. Lead 36 may be upset into a kink engaging the appropriate printed circuit board holes to lock the capacitor against tilting or lifting pending soldering (Figs. 4, 5, not shown), or the lead may be knurled for the same purpose. The portions of the leads embedded in the capacitor ends may be zig-zag form (Fig. 9, not shown) or may be squared, flatted, knurled, or roughened (Figs. 10-15, not shown) where they areembedded in the capacitor ends to prevent rotation and consequent poor contact with the electrodes. The long and short leads may emerge from the end sections of the capacitor in which they are embedded at right angles to each other (Figs. 7A, 7B, not shown).

Title: Hydraulic driving means for racks
IPC: C10J3/34
Filed: 1949-06-23
Abstract: 681,005. Ratchet gearing. HUMPHREYS & GLASGOW, Ltd., and HOBBS, A. F. May 18, 1950 [June 23, 1949; July 14, 1949], Nos. 16752/49 and 18642/49. Class 80 (iii). [Also in Group XXIX] A toothed member 15, Fig. 1, driving a rack 16 is reciprocated by two coaxial hydraulic main rams having cylinders 13, 12 and the driving member 15 is urged by hydraulic means e.g., auxiliary rams 22, 21 into and out of engagement with the rack 16 when the main rams are substantially stationary. The member 15 is slidably mounted in a housing 14 integral with the main ram plungers, and is displaced radially to and from the rack 16 at the beginning and end of the working stroke of the main rams by an eccentric 17 rotatable in an arm 35 pivoted to the member and actuated by the rams 22, 21 through a lever 23 and coupled shafts 19, 18. In operation liquid under high pressure is first supplied through a conventional hydraulic reversing valve (not shown) to the ram 22 to effect engagement of the members 15, 16 whereupon a bell crank ]ever 24 opens a valve 25 to supply high pressure liquid to the main ram cylinder 13 to effect the working stroke; the cylinder 12 being exhausted through a poppet valve 26 into a header or tank forming a low pressure reservoir. The return stroke is effected on operation of the reversing valve to exhaust cylinders 13, 22 and valve 25 to drain, and high pressure is supplied to cylinder 21 to disengage the members 15, 16 whereupon the lever 24 opens the valve 26 to supply low pressure liquid to the cylinder 12. In a modification the driving ram cylinder 13 is of smaller diameter than the return ram cylinder 12, and on the return stroke the cylinder 12 instead of being supplied with low pressure is put into communication with the cylinder 13 by an auxiliary valve actuated by the shaft 19. In a further modification fluid is supplied through a main reversing valve 36, Fig. 12, to the cylinders 12, 13 and through ducts 37, 38 to the auxiliary rams simultaneously. Ports 20a, 20b throttled by plungers 19a, 19b restrict the initial movement of the main rams at the start of the working and return strokes until the auxiliary rams have effected engagement and disengagement of the driving member. In a further modification wherein fluid is supplied to the main auxiliary ram cylinders simultaneously, a separate throttling unit actuated by the driving member restricts fluid flow to and from one cylinder only at the end of each stroke.

IPC: A01M7/00
Filed: 1957-05-27
Abstract: 844,868. Crop sprayers. DRAKE & FLETCHER Ltd. Aug. 18, 1958 [May 27, 1957; June 28, 1957], Nos. 16806/57 and 20467/57. Class 69 (3). A spraying unit for detachable mounting on a vehicle, e.g. on the rear of an agricultural tractor, comprises a frame support 1 on which are mounted centrifugal fans 14, 15 with spraying nozzles 21 located in their outlets 19, an air compressor 32 or a liquid pump which effects or assists in the delivery of liquid spray from the nozzles, and a shaft 23 adapted for connection to a power take-off of the vehicle whereby the fans and compressor or pump can be driven. As shown, the unit is mounted on the rear of a tractor by means of rods 4 extending from plates 5 on the frame and engaged by arms 6 of the tractor; a U-shaped link 7 is pivoted at its free ends to the apexes of the plates 5 and the mid-point of its upper cross-member has a lug 8 for connection to the tractor. The side arms of the link are slotted and each slot takes a screw which engages any one of several holes in a plate secured to a standard 3 at the front of the frame. The compressor 32 is supported on crossmembers at the top of the standards 3 and is driven by a belt 33 from a pulley on a shaft 28 driven by a belt 30 from the shaft 23. A tank 38 for spray liquid e.g. insecticide is detachably attached to brackets 35 on the standards, and a flexible pipe feeds liquid from the tank to the nozzles. A flexible pipe feeds compressed air from the compressor to the tank via a pressure reduction valve and a further pipe delivers compressed air at unreduced pressure to the spray nozzles. The fans have a common shaft 13 connected to shaft 28 and mounted in bearings 12 on a support 9, and the fan casings 10, 11 are arranged back to back with air inlets 16 and 17 respectively. The casings are freely rotatable about their axes to enable their arcuate slot-shaped air outlets to be directed as desired, and a spring-loaded detent 40 on one casing and arranged to detachably engage the other, allows one casing to be angularly adjustable relative to the other. The casings are rotated by a crank handle 44, shaft 41 and a belt &c. drive. For the purpose of spraying larger volumes of liquid, a larger tank on a trailer is coupled to the rear of the unit and has an air inlet pipe within and at the base of the tank to which the compressor outlet is connected. An agitation of the liquid in the tank is thereby produced, and the pressure therewithin forces the liquid therefrom and through a flexible pipe to the nozzles. Alternatively the compressor is replaced by a liquid pump whose intake is connected to the tank and its outlet to the nozzles. Specification 749,286 is referred to.

Title: Improved method for receiving wireless signals
IPC: H04B1/26
Filed: 1919-07-09
Abstract: 137,271. Armstrong, E. H. Dec. 30, 1918, [Convention date]. Wireless telegraphy.-In a method of receiving waves of very high frequency, which reduces interference by atmospherics, the incoming energy is utilized to produce oscillations of a different, locally-determined, supersonic frequency (e.g. by combining with local energy to produce beats of a frequency of a million per second), and the supersonic currents are then amplified, and detected in known manner. The supersonic currents may be combined with other local currents to produce beats of audible frequency, or to produce beats of a lower supersonic frequency, which may be amplified before detection. In the arrangement shown in Fig. 1, the incoming waves and local energy are led by coils 1, 6 to the circuit 2, 3, the resultant current being converted by rectifier 4 into currents of supersonic frequency, which are led to an amplifier 8 and detected in the circuit 9, 10. For receiving undamped waves, a heterodyne 11 supplies current to produce beats of audible frequency in the circuit 9, 10. The crystal 4 and local source 6 may be replaced by a valve acting as a rectifier and as a source of local energy. Reference has been directed by the Comptroller to Specifications 133,306 and 135,177,
