Title: Improvements in and relating to stereotype plate casting machines
IPC: B41D3/00
Filed: 1930-02-04
Abstract: 346,891. Casting stereotype plates. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Wood Newspaper Machinery Corporation; 501, 5th Avenue, New York, U.S.A.) Feb. 4, 1930, No. 3795. [Class 100 (ii).] In a stereotype casting-machine of the type in which the mould is constituted by a core and a back reciprocable to closed and open position, the back is power-operated, and the power is shut off automatically at each end of the movement of the back. The back B of the mould is movable to and from the core C by means of a pair of toggles actuated by a shaft 4 rotated from a motor 1 by worm gearing 2, 3. The shaft 4 carries arms on which are mounted pins 9, 10 adapted to move the handle 7 of a switch 8 controlling the movements of the motor. The handle 7 is moved manually to set the motor in operation to close the mould, and when the closing movement is completed the pin 9 engages the handle 7 and opens the switch. To open the mould, the handle 7 is moved in the opposite direction to reverse the motor, and when the back is fully withdrawn the pin 10 opens the switch. The piston of the metal-supply device is under similar control. When the mould is closed, a handle 21 is moved to close the switch of a motor 12, which is connected through worm gearing 13, 14 and lever 15 to the piston-rod 16. When the piston is raised, a pin 9a on the lever 15 engages and moves the switch over to reverse position. The piston is thus returned to its original position, when the switch is moved into neutral position by a pin 10a.

Title: Improvements in electric motor starters
IPC: H01H19/46
Filed: 1924-02-20
Abstract: 234,171. Cox, F. B. Feb. 20, 1924. Controllers, drum; controllers, multiple rocking bar; overload and no-volt releases.-In switch gear for motor starting and other purposes a common handle operates two switches against throw-off springs through disengageable mechanical couplings which are provided with independendent tripping means, a detent associated with the handle forming an anchorage for both switches until the respective couplings are tripped. For motor starting one of the switches may be a line circuit-breaker and the other a star-delta or other connection-changing switch. The tripping action may be effected automaticcally by no-volt, overload or time lag devices, or manually by a push device. Means may be provided to reduce the sensitiveness of the overload device during the first stage of the action, and to impart a quick movement to the switches in operation bv the handle. Fig. 1 shows an elementary form of starter according to the invention and Figs. 2 and 3 show the operation and tripping action of one of the two switches A, B, Fig. 1. A handle C by movement from right to left carries a circuit-breaker arm a<1> on to a lineclosing contact a<3>, where it is retained against a spring a<6> by a handle latch c<6>. The closing action places a spring d<3> in a position where it tends to operate a trigger lever d<1> for the purpose of breaking the toggle link c<3>, c<4> and allowing the circuit-breaker to be opened, the trigger lever being normally held out of operation by a novoltage coil d<4>. The handle also operates in the same manner a switch b<1>, which may be a stardelta starter. A time lag for the tripping action may comprise a device with two adhering oiled plates, one of which is slowly pulled away from the other Instead of toggle linkage couplings. shaft couplings in the form of single-tooth ratchets and disengageable pawls may connect the handle to the switch members.

Title: Apparatus for arranging in sequence items of digital information
IPC: G06F7/08
Filed: 1954-08-10
Abstract: 731,797. Electric digital data storage apparatus. BLACKLOCK, D. S. Aug. 10, 1954, No. 4397/51. Class 106 (1). Apparatus for rearranging digital information in a desired sequence comprises means for storing information words in a first sequence, means for reading out each information word from the storage means in the form of electrical signals, means for storing a characteristic element of information selected in accordance with the sequence desired, means for selecting a particular element of each information word for comparison with the stored characteristic element, and comparing means controlling signal-gating means according to whether the compared elements agree or disagree thereby allowing any word containing the preselected characteristic element to pass to further storage means before any word not containing the preselected characteristic element. In the described embodiment a magnetic drum 86 is used for storing information words in binary form, one word on each track. Pulses on a clock track picked up by a read head 83 operate a counter 84 having a cycle equivalent to one rotation of the drum. The output from this counter, together with that of a second counter 81, preset to give an output signal when the position " r " of the binary element which is to control the selecting operation is reached, is fed to a coincidence gate 85, the output of which is applied to a further coincidence gate 89. A third coincidence element 88 compares the selecting binary digit pre-set in a device 82 with the elements on the drum which are being read by the pick-up head which is in circuit with a switch arm 87. Thus, the coincidence circuit 89 passes a signal when the rth binary digit of a word is the same as that stored in the device 82. This signal serves to operate a trigger device 90 which opens a gate 98 long enough for the complete word read from the drum 86 to pass through at delay element 97 (delay " r ") to the next available track on a second magnetic drum 100. A stepping switch 99 is moved on after each word recorded on the drum 100; the stepping switch 87 moves on after each complete rotation of the drum 86. When all the words on the drum 86 have been examined, the digit in the device 82 is changed and a second scanning by the switch 87 results in those words previously passed over now being recorded successively on the drum 100. The latter storage may be supplemented by further storage means such as magnetic tape or wire.
