Title: Improvements in and relating to magnetic stores
IPC: G11C7/00
Filed: 1966-07-21
Abstract: 1,113,330. Magnetic storage arrays. INTERNATIONAL BUSINESS MACHINES CORPORATION. 21 July, 1966 [17 Aug., 1965], No. 32705/66. Heading H3B. In a magnetic store comprising orthogonal mode storage elements arranged in rows and columns, bit/sense row conductors are connected in pairs to bit drivers and the conductors of each pair are also connected to separate inputs of a differential sense amplifier so that common mode noise is rejected. In order to reduce the length of a read-write cycle the bit current is maintained at the end of the write portion of each readwrite cycle so that it extends almost to the end of the read portion of the subsequent cycle. Transients occurring during the rise time of a bit pulse may cause saturation of the sense amplifier but the amplifier has time to recover during the write period. Subsequent transients caused by the fall of the bit pulse occur after reading. The output of the sense amplifier may be strobed at an appropriate time during the read period. The storage elements may be thin films, multiapertured ferrite devices or chain store devices.

Title: Improvements in sheet feeding mechanism
IPC: B65H3/08
Filed: 1936-06-09
Abstract: 476,524. Feeding sheets. CROWN CORK & SEAL CO., Inc. June 9, 1936, No. 32788. Convention date, May 8. Divided out of 476,503. [Class 100 (i)] In a sheet-feeding mechanism in which separation of the sheets is effected by the aid of suction cups 132 acting on the rear edge of the pile, the cups are mounted and operated in such a manner as to maintain the top sheets of the pile of sheets 51 with their front edges in accurate register with the pile gauge 61. The cups are given a diagonal movement so as to bend the corner rear edges of the sheet in a diagonal direction, and as the cups are raised from the pile they are moved towards the gauge 61 so as to maintain the front edges of the sheets in contact with the gauge. The invention is described in connection with the machine described in Specification 476,502, in which the separated sheets are advanced by suction cups 172 to sheet forwarders 64, 66, as described in Specification 476,503. The cups 132 are carried by pivoted members 616, each formed of members 615, 617, the member 617 being pivoted at 618 to a bracket 619 carried by a hanger 620 supported on a casing 114 by means of a pin 621 which permits the hanger to swing as described in Specification 476,525. The member 615 is connected by parallel links 624 to the member 617, and normally a spring 625 keeps the links moved towards the rear of the pile so that the two surfaces 623, 622 of the members are in contact. When the cups 132 are raised from the pile by the action of a dished cam on rollers 607 mounted on levers 608, each connected by a universal joint 611 and a rod 610 to a member 615, the member 616 is raised as a whole and the member 615 is moved by the links 624 so as to move the member 615 in a forward and upward direction relatively to the member 617, and this causes the separated sheet to tend to move towards the gauge 61. The final position of a cup 132 is indicated by the dotted lines in Fig. 3.

Title: Improvements in and relating to loading apparatus e.g., for loading gears on a gear shaving machine
IPC: B23F23/06
Filed: 1956-10-30
Abstract: 823,985. Gear - finishing. NATIONAL BROACH & MACHINE CO. Oct. 30, 1956 [Oct. 31, 1955], No. 33087/56. Class 83 (3). A gear-finishing machine comprises periodically operating means 31 receiving and positioning gears G in axial alignment with a rotatable work-holder 20, a transfer member 26 periodically engageable with a gear aligned with the holder by the positioning means 31, and means to shift the transfer member axiallyinwardly toward the work-holder to displace a gear from the positioning means on to the holder. In a crossed-axis-machine for shaving internal gears, a cutter-slide 14 is moved to- and-from the chuck 20 by a pneumatic device 21. If there is undue resistance to the feeding movement of the cutter, denoting misalignment of the teeth of the cutter and work, the increase in pneumatic pressure opens a spring- operated valve; a jogging action ensures until the teeth engage. If the resistance reaches a certain limit, a switch is operated to withdraw the cutter and re-advance it. The workengaging ram 26 is reciprocated by pneumatic means 28 and is oscillated by similar means 29 acting through rack-gearing. Gears G fall from a shaft 30 under the control of an escapement 30<SP>1</SP> into the cradle 31, which is moved by pneumatic means 32 to bring the gear into a position where the ram 26 may push it into the chuck. After machining, the finished gears are ejected into a shoot 35. In a modification, a gear is moved into alignment with the chuck by a cradle 40, Fig. 5, which is withdrawn during machining, and is then advanced to collect the finished gear. As a pneumatic device 43 pushes a gear from a shoot 38 into the cradle, the gear pushes the finished gear into a shoot 44. Chucks.-The chuck 20 is secured to a frame 56 on a hollow spindle 57 and carries an adapter sleeve 45 in which the gear is clamped. The clamping is effected by three jaws 47 on rods 49 moved axially by a pneumatic device 18 and a tube 61. The rods each have helical slots 51 engaging fixed pins 52 so that the jaws are swung and pulled into engagement with the work as the tube 61 is moved rearwardly. Ejector rods 68 are actuated by a pneumatic device 19 and a rod 73, the ram 26 being swung down to act as a back-stop. The pneumatic devices may have adjustable stops on their piston-rods to limit accurately the movements. The machines may be operated hydraulically. Cutters.-To assist in engaging the cutter with the work, the teeth of the cutter may have tapered leading edges.

A two-pole electrical static switching device comprising a complementary pair of bipolar transistors having their respective emittercollector paths connected in the respective pole circuits through the device, and their bases respectively connected to the source and drain electrodes of a unipolar F.E.T. the grid of which serves to receive a control signal to operate the device between the ON and OFF conditions. In Fig. 3, complementary transistors TR1 and TR2, TR3 and TR4, form the switches which connect devices TL1, TL2, respectively, to the common supply lines of C1 and hence to each other. A negative pulse, or 1, appearing at both CP1 and CP2, will turn on respective FETS 1, 2, and hence connect devices TL1 and TL2 via Cl. These pulses are obtained from AND gates A1, A2, fed by a synchronizing 1 pulse and a pulse from a shift register which determines whether the FET is turned on. It is possible to hold a FET turned on by means of high-frequency pulses because of the charge retained by the gate-substrate capacitance. Fig. 2 shows a possible switching matrix using cross-over points of Fig. 3.

Abstract: 179,217. Marks, E. C. R., (Barber-Colman Co.). Nov. 29, 1920. Yarns, warping and beaming.-In a yarn winding machine the yarn mass being wound is unyieldingly pressed against its driving-drum by means actuated by yarn-controlled means to accommodate the increase in size of the yarn mass, while maintaining the pressure. The invention is described as applied to a warping-machine The beam B is rotated by a drum 122 and is mounted in a pair of arms 120 each connected by means of screwed rods 413 geared with a rotary shaft 418 mounted in levers 422 which are pivoted at 423 and connected at their rear ends to crank arms 425 fixed upon a shaft 182. The shaft 182 is provided with weighted arms 427, which cause a downward pull to be exerted on the rods 413, and with an arm 437 which is adapted to obstruct the movement of a lever 429 carrying a pawl which engages a ratchet-wheel on the shaft 418. The lever 429 is connected by means of a spring 436, Fig. 5, to a link 431 operated by a crank-pin on the drum-shaft. A dash-pot 439 is provided to damp the vibrations of the arms 427. The arms 120, owing to the dash-pot and the interiot of the parts, do not yield to the upward pressure caused by the high portion of an eccentric yarn mass, so that the high portion is rolled down and the yarn mass restored to cylindrical form. As the varn mass increases in diameter the arms 120 are forced upwards and, through the levers 422 and crank arms 425, lower the arm 437, thereby allowing the lever 429 to swing and turn the ratchet-wheel and the screwed rods 413 until the arm 437 again obstructs the lever 429. The arms 120 may be lifted and lowered manually by means of sprocket gearing 444 when removing or inserting a beam. The trunnions of the beam are mounted in bearings in a spherical socket in the arms and are retained therein by a spring catch 408.
