IPC: B41F31/06
Filed: 1961-11-06
Abstract: 950,121. Feeding sheets to printing machines. LINOTYPE & MACHINERY Ltd. Nov. 30, 1962 [Nov. 6, 1961], No. 39656/61. Headings B6B and B6C. A printing press of the kind provided with swing grippers 35 or like sheet transfer devices which move between the feed board 41 and cylinder or sheet conveyer grippers includes a light projector 47, a light reflector 50 carried by the swing gripper device, and a light receiver device including a photo-cell 52 which receives a light beam if no sheet is present when the grippers 35 are in the sheet-accepting position and provides an output to trip the press. Feeding sheets.-The feed board 41 is provided with pivotally mounted front stops 42 and the grippers 35, which deliver the sheets to the grippers 44 of the impression cylinder 1, are controlled by a cam 37. The lamp 47 is provided with a collimating lens tube 48 and the prism 50 reflects light through a hole in the board 41 to the photo-cell if no sheet is present at the stops 42 of the backswing of the grippers 35. The embodiment of Fig. 6 (not shown), is provided with three light-projecting and lightreceiving systems of the type described so that the press is tripped if a twisted sheet is present on the feed board. Cylinder machines.-The output from a photo-cell may be used to raise the impression cylinder 1 from the press bed, not shown, or to stop the press, and is fed via an amplifier 55 and a relay 56 to a solenoid, Fig. 5 (not shown). A main control valve 14 is operated in timed sequence so that hydraulic jacks 10 are actuated to lower the impression cylinder 1 against the pressure of springs 7. A relay valve 13 is manually adjustable to control the impression pressure. The solenoid when energized operates a valve 20 positioned between the valves 13 and 14 so that oil under pressure in the hydraulic system, Fig. 3, will exhaust back to the reservoir 12 so that the impression stroke is prevented. When the solenoid is energized an audible and/or visual warning device, e.g. a lamp 63 may be operated. In the embodiment of Fig. 9 (not shown), the lamp is arranged above the feed board.

Abstract: 1364518 Digital transmission; cypher system CIBA-GEIGY AG 24 Aug 1971 [24 Aug 1970 22 July 1971] 39759/71 Heading H4P In a system for cyphering messages particularly where access is required by more than two participants, short access time is reconciled with long transit time by changing the transit time from a larger to a smaller value periodically in dependence on the cypher code; the transit time thus fluctuates between defined limits. The apparatus comprises a plurality of shift registers which derive a code pulse sequence from a long period sequence and a cypher code, the shift registers being interconnected by logic circuits so that the binary value of each code pulse is defined by the value of control pulses supplied earlier, each cypher pulse remaining unaffected by that part of the control pulse which occurs before the affected code pulse during the transit time, which is changed at determined intervals from a larger to a smaller value. A simple arrangement comprises two parallel sub code generators each having a controllable feedback path, e.g. 8<SP>1</SP> having a control sequence v passing in parallel through a modulo-2-mixer 47<SP>1</SP> to conductor 121. A separate 2 stage binary step down element 114<SP>1</SP> issuing data flow instructions in conjunction with AND gates 75<SP>1</SP> cause intermittent code circulation of data in shift registers 11a<SP>1</SP>, 11b<SP>1</SP>. While data flow through generator 126<SP>1</SP> is continuous, in 126<SP>11</SP> the data flow is gated by AND gates 76<SP>11</SP> alternately through shift registers 11a<SP>11</SP>, 11b<SP>11</SP>. Data flow passes through mod-2 mixers 140<SP>1</SP>, 131<SP>1</SP> and 129 to AND gate 99 in which only every nth bit is selected by slow timing source (TB) (not shown) and used. The feedback paths 8<SP>1</SP>, 8<SP>11</SP> are switched by the second inputs, i.e. 43<SP>1</SP>, 43<SP>11</SP> of AND gates 83<SP>1</SP>, 83<SP>11</SP>. Switch on time is substantially larger than the switch off time which is only long enough for incoming data to occupy store positions. A feedback path8*, controllable manually by switch 125, may be incorporated, which is also controlled by the 43* input which is interrupted at the same time as both 126<SP>1</SP>, 126<SP>11</SP> which prevent the cypher routine originating at a time position in which only feed forward is effected. The shift registers may be of different length and preferably all different prime numbers; an example specified may have 137, 211, 157, 223 stages respectively. Data flows from constantly differing time zones are combined with each other by the different lengths of the shift registers. A number of other arrangements are described in the Specification.

Title: Electromagnetic linear motion actuating device
IPC: H02K7/065
Filed: 1973-08-23
Abstract: 1389797 Electromagnets BROWN BOVERI & CIE AG 23 Aug 1973 [23 Aug 1972] 40078/73 Heading HIP A linear electromagnetic actuator (Fig. 1) comprises a movable rod 1 sliding in plastic bearings 51, 52 recessed into limbs 41, 42 of non- magnetic U-frame 4. The rod also loosely fits a bore 23 of an armature 2 retained centrally by coil springs 61, 62 positioned on the rod between rectangular plastic washers 71, 72; 81, 82. Springs 91, 92 recessed in side members of the U- frame retain bearings 51, 52 against the rod 1, and lugs 10 (Fig. 2) conjoin the limbs 41, 42 of the frame, while carrying stop abutments 101 locating the armature in mid position. Two electromagnets 31, 32 are carried by limbs 41, 42 to displace the armature in either sense. In operation excitation of either electromagnet exerts force on the free end of the armature and tilts it against the appropriate spring to grip rod 1 in bore 23, and a resolved force along the rod axis (Fig. 3, not shown) displaces the rod relatively to bearings 51, 52 in an appropriate direction against their friction the resistance of the member to be actuated, and the resistance of the respective spring. On de-energization the translational force is removed and the armature is repositioned into its mid position by the springs, while rod 1 is left retained by bearing friction in its displaced position. The operation is repeatable by further energization of the appropriate electromagnet. The device is applicable to control system adjusters, ventilator or valves.
