Title: Improvements in or relating to printing machines
IPC: C09B37/00
Filed: 1959-04-28
Abstract: 898,168. Typewriters &c. COMPAGNIE DES MACHINES BULL. April 28, 1959 [May 14, 1958], No. 14544/59. Class 100(4) A printing machine comprises continuously rotating type wheels for printing on record cards or separate sheets. In the example described data on a record card is analysed column by column and similarly printed on the card itself. Cards are placed in a magazine 21 and are removed by a reciprocating knife through slots 68, 69 to be fed by rollers 51-54 over a contact plate 116 past the analysing and printing position to a receiving compartment 23. The cards are held in the magazine 21 out of the feeding position until an electromagnetic device allows them to be lowered into the path of the extractor knife. A shaft 29 mounts a printing wheel 37 and a magnetic distributer DM drives in synchronism therewith. The printing wheel is in line with the card analysing brushes 85 which scan the record cards continuously column by column as they pass. A hammer 111 which is actuated by an electromagnet 93 effects impression on the card C by means, of an ink ribbon 96 when the character on the print wheel 37 appropriate for the datum of a column being analysed is in the printing position. The wheel 37 rotates once for every column analysed and is divided into five equal parts four of which contain up to nine characters arranged in a helix. The magnetic distributer has nine coils which can each produce a pulse during each part of a column sensing cycle as the corresponding character of a corresponding part of the type wheel 37 is in the printing position. Pulses derived from the eleven position code sensed column by column are first fed through a decoding diode matrix which reduces them to a seven position code for feeding to a double relay contact pyramid which sets up a circuit to the appropriate distributer coil. The appropriate part of a column cycle for the connection to the coil is selected by cam actuated contacts each of which is closed once every column cycle and only one of which is in the circuit set up by the relays when the column is sensed. Thus a circuit is set up to a distributer coil to receive a pulse when the appropriate character is in the printing position and the pulse is fed to a control grid of a triggering tube which allows a condenser to discharge through the hammer electromagnet 93 to effect impression. The condenser is charged during the blank part of each column cycle. In modified arrangements a seven position record card is used in which case a diode matrix is unnecessary the pulses being fed directly to the double contact relay pyramid. In other cases a double deck record card is used in conjunction with two analysing and printing devices while all the columns may be sensed simultaneously and a printing wheel for each column used to effect line printing on a separate record sheet. Card feeding can be stopped by manually opening contact or by contacts in series therewith opened when the card supply magazine 21 is emptied or the receiving compartment 23 becomes filled.

Abstract: 1469702 Burner control for furnaces KOPPERS-WISTRA-OFENBAU GmbH 3 April 1974 [14 April 1973] 14898/74 Heading F4B In a furnace having a plurality of gas or oil burners of variable heat output to heat charge material therein, the heat output to the furnace is controlled by cyclically switching at least two burners in such a way that when one burner is at a certain preset output level the other is operating at another preset output level. The preset output of one of the burners is at least 50% of the maximum output of one of the burners subject to the cyclical switching. The preset output levels and the duration of the periods of operation at the output levels is so selected that the average total burner output within a cycle matches the required furnace heat input rate. In one embodiment with a furnace having four burners (Fig. 2) the furnace may operate as indicated by Fig. 3 with the four burners 6, 7, 8 and 9 preset to a first output (at least 50% of the maximum) illustrated by the full line and a second output level illustrated by the blank space when the burners are idling or switched off. In the Fig. 5 embodiment the burners operate on a cycle having a first output level illustrated by the double lines indicating burners at maximum output and a second output level shown by the full line when the burners are at some intermediate output. The method may be applied to a tunnel furnace as in Fig. 7 with burners 10 and 12 causing circulation of furnace atmosphere in one direction and burners 11 and 13 causing circulation in the opposite direction. The method may also be applied to furnaces having two or more zones with independently controllable burners or burner groups, the method may be applied to the zones as well as to the burners or burner groups within the individual zones.

Abstract: 826,154. A.C. commutator motors. BRITISH THOMSON-HOUSTON CO. Ltd. May 17, 1957 [May 18, 1956], No. 15596/56. Class 35. The commutator brushes of one or more phases in a Schrage type machine are transposed to positions displaced by 180 degrees electrical from their normal positions and have either their electrical connections to the stator phase winding or their rockers interchanged. By this means a redistribution of the current at the commutator is achieved, or for small machines, the brush groups may be compressed to cover small commutator arcs so that sufficient room is left for the brushes to be rocked on a single track instead of the usual two separate tracks. In a single-phase form, the brushes D 1 , D 2  connected to stator phase SD are transferred to the opposite side of the commutator and their connections reversed as shown in Figs. 6 and 8, the brushes remaining on the same rockers and in separate tracks. Fig. 4 shows a small four-pole machine in which only half the number of brushes is used by avoiding parallel-connected brushes and using equalizing connections. With the brush groups D 1 , E 1 , F 1  and D 2 , E 2 , F 2  running in the same track, the permissible angle of movement " α " of the rockers R 1 , R 2  is insufficient. By displacing brushes F 1 , F 2  by 180 degrees electrical so that they lie between brushes D 2 , E 2  and D 1 , E 1  on opposite rockers, as shown in Fig. 9, the angle " a " is increased to an acceptable amount for proper control of the motor. It is described how the invention may be applied to machines of higher pole and phase numbers. Specification 25358/11 is referred to.

Abstract: 1340101 Optical projection apparatus FUJI SHASHIN FILM K K 18 May 1971 [18 May 1970] 15645/71 Heading G2A [Also in Division B8] A device for guiding sheet of film e.g. microfiche from a viewing position to a magazine 16 includes two guide plates 4, 4' which may approach the sides of a microfiche carried by support 1 as the support 1 passes between them. As shown the guides 4, 4' are carried by rods 3, 3' which pass through fixed plate 2 and which are connected by the arrangement shown in Fig.3. The movement of the microfiche bearing support 1 is sensed by lever 10 contacting the projection 17. The lever 10 has a pin 11 and slot 8 connection with lever 7 which pivots about pin 9. The spring 12 urges the lever 10 clockwise about pin 18. The lever 10 transmits the sensed movement of the support 2 only when the projection 17 engages its end and the support is moving towards the magazine 16. This movement rotates the lever 5 and the clutch mechanism 6 then permits the rod 3 to rotate. Plates 31, 31' permit the rod 3' and guide plate 4' to rotate equally and oppositely to the rod 3 and guide plate 4. However slot 15 limits the range of movement of rods 3, 3' and guide plates 4, 4' so that, when the described movement of the support 1 has caused the guide plates 4, 4' to be at their closest to the support 1 and to thereby guide the microfiche into the magazine 16, further movement of the lever 10 is absorbed by the spring of clutch 6.

Title: Composite distensible sheet materials and methods of manufacturing the same
Filed: 1935-05-29
Abstract: A porous distensible material comprises a layer of fabric such as stockinette and a perforated elastic layer of rubber or the like, the layer of rubber being in the form of a system of interconnected ribs or strips formed and simultaneously united to the fabric by moulding under pressure, and enclosing at least 100 apertures per square inch. The strips may form a regular or irregular pattern, and may leave exposed 50 per cent or more of the fabric surface.  A further ply of fabric may be applied to the uncovered side of the rubber.  As described, a sheet of unvulcanized rubber is superposed upon a distensible fabric on a heated platen, and is moulded and united to the fabric by a heated die; or the moulding may be effected by passing the superposed layers of fabric and unvulcanized rubber between a plain and a profiled heated roll.  Products comprising a layer of rubber between two fabric plies, or of two layers of rubber with a single intermediate fabric ply may be thus made.  Products in which threads of the textile fabric or fabrics are displaced and embedded in the rubber may be made by subjecting an assembly of one unvulcanized rubber layer placed under a ply of fabric or of one or more unvulcanized rubber layers between two or more plies of fabric, to pressure-moulding from one or both sides by dies having tapered ends, e.g. of pyramidal or conical shape; the moulding devices may be in the form of rolls.  Vulcanization may be completed in the moulding state, or subsequently.  When the rubber layer is exposed, it may be differently coloured from the fabric, and may be further ornamented with grooves, points, &c.
