Title: Improvements in or relating to rotary printing machines
IPC: B41D1/00
Filed: 1966-08-22
Abstract: 1,131,755. Rotary printing saddle. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. 22 Aug., 1966 [11 Sept., 1965], No. 37598/66. Heading B6C. [Also in Division B5] Printing saddles for fixing flexible printing plates on to plate cylinders of rotary reliefprinting machines are produced by applying a number of resin-impregnated glass fibre mats to an auxiliary cylinder which has the same diameter as the plate cylinder and subsequently machining the surface of the hardened laminate by turning or grinding to the required thickness. Fig. 1 illustrates in elevation the auxiliary cylinder 1 with axially parallel strips 2 diametrically opposed to each other which can be detached and serve as boundaries for the printing saddles 3, two of which can be made on each cylinder. Where the saddles are adaptable for inner clamping, profile strips 5 which interact with hooks on the printing cylinder when in use, are provided extending parallel to the axis. The way in which the glass fibre mats are built up is shown in Fig. 2, a part longitudinal section on the line II-II of Fig. 1, and Fig. 3 a section at point A on Fig. 1. A resinimpregnated glass fibre mat 6, which is both longer and wider than a printing plate to be placed upon it, is pressed firmly on to the cylinder into the corners provided by strips 2 and 5 and the detachable profile disc 4 which defines the curved edge of the saddle 3. After similar application of further mats 6, their ends 6a, 6b, 6c being indicated by dotted lines in Figs. 2 and 3, a glass fibre tress 8 is inserted along the whole of the edge of the saddle serving as a reinforcement for the mats and also for the grooves 11 (Fig. 4, not shown) which are present in the saddle as a result of the profile strips 5 on the auxiliary cylinder. The edges 6a of the top mat are then laid inwardly over the tress 8, followed by edges 6b and 6c, with suitable positioning of further smaller mats in between so as to build the saddle to the required thickness. The auxiliary cylinder 1 is then mounted on a turning fixture and the surface of the saddle 3 is machined to a smooth finish.

IPC: B23B3/28
Filed: 1959-11-18
Abstract: 936,803. Trueing grinding wheels. SNOW & CO. Ltd. Nov. 9, 1960 [Nov. 18, 1959], No. 39028/59. Class 60. [Also in Group XXIX] A copying device for trueing profiled grinding wheels such as are used in machines for grinding the slideways of lathe beds comprises a stylus 29 coacting with a template 37 and fixed to one end of a bar 26 the other end of which carries a diamond-tipped tool (not shown) for operating on the grinding wheel, springs 33, 65 for urging the stylus and tool assembly into engagement with the template and grinding wheel, and a servo-device consisting of a fixed piston contained in a movable cylinder 8 for moving the spring abutments 20, 35 to maintain a substantially constant degree of spring compression. The piston is secured by an eye 15 to a bracket 16 on a carriage that is given a traversing motion parallel to the axis of the grinding wheel by a double-acting cylinder (not shown). The cylinder 8 is mounted in the carriage, which is slidable on guides 3, by leaf springs 9, 10 which permit vertical movement but prevent rotation. The bar 26 is clamped to a bracket 23 by screws 30 which permit angular adjustment of the bar together with the stylus and tool to suit the profile being followed. Leaf springs 31 allow vertical movement of the bracket 23 relative to the cylinder 8 but prevent rotation, and stops 66 limit upward movement of the bracket 23. The arrangement is such that as the template is traversed by the stylus the vertical movement of the latter causes deflection of a valve 18 from its neutral position relative to a ported housing to connect the two sides of the piston to a pressure fluid supply and exhaust in such a manner as to cause the cylinder and valve housing to follow-up the movement of the valve. As the stylus approaches the end of a traversing stroke the supply and exhaust conduits 57, 58 to the valve may be reversed by a manually-operable valve (not shown) so that an upward movement of the stylus as it leaves the end of the template results in a downward or withdrawing motion of the cylinder 8. An automatic control valve may also be provided to effect withdrawal of the stylus at any given point by engagement with stops on the template. The cylinder 8 and the traversing cylinder are fed from a common source of supply which is arranged so that the supply to the cylinder 8 has priority over that to the traversing cylinder.

Abstract: 1407091 Radio navigation system LITCHSTREET CO 24 Aug 1972 [15 Sept 1971] 39547/72 Heading H4D Although the Specification describes a comprehensive S.S.R. navigation system, possibly involving more than one S.S.R. 71, Fig. 1, each with a characteristic pulse repetition co-operating with an "own" craft 72 carrying a transponder and a second craft 73 also carrying a transponder, wherein it is possible, on one's "own" craft 72, to determine (a) the slant range Y between the craft, (b) the differential distance X between the two craft's radar ranges, (c) the "own" craft's bearing from the S.S.R. 71 and (d) the bearing (#+#) of the other craft from the "own" craft, the claims of the present Specification refer to determining the slant range between the two craft wherein the time interval between transmission of a signal from the own craft and reception of the resulting reply from the other crafts transponder is determined. An additional receiver 63 is provided which can receive replies from the other craft's. A device 66 determines whether the other craft is within a danger zone around "own" craft by monitoring the S.S.R. replies of the other craft. If so, line 61 is activated to cause transponder 60 to transmit a "proximity situation message" in addition to its normal S.S.R. replies. This activates the transponder 60 of the other craft which transmits a signal back to transponder 60 of "own" craft. Range computer 70 determines the time interval between transmission at "own" craft transponder 60 and subsequent reception of the reply from the other craft to determine Y the slant range. Additionally, computer 70 determines distance X by measuring the time interval between the response by "own" craft and reception at own craft of the response from the other craft to the same interrogation from S.S.R. 71. Computer 76 determines the time interval between pointing of S.S.R. 71 to Magnetic north, when it transmits a North pulse, and its pointing towards "own" craft 72, hence determining own craft bearing to the S.S.R. Computer 75 forms cos<SP>-1</SP> X/Y to give 0, the bearing of the other craft relative to the line passing through S.S.R. 71 and "own" craft 72. A magnetic compass provides H "own" craft's magnetic heading. Computer 75 then determines B, the other craft's bearing relative to own craft's heading, from B=#+#-H. Indicators 74, 77, 78 display the bearings and indicator 53 gives a craft proximity warning. A detailed description of the system of Fig. 1 is given (detailed circuitry, Fig. 3, not shown).
