Title: Apparatus for measuring without contact the position of a luminous body
Inventor: PODKOVYRIN EVGENY YAKOVLEVICH
IPC: G01D5/26
Filed: 1966-11-11
Abstract: 1,194,881. Photo-electric position measurement. INSTITUT CHERNOI METALLURGII. July 26, 1968 [April 26, 1967], No.12155/67. Heading G1A. The position of a luminous body with respect to a fixed point is measured photo-electrically. In the measurement of the sagging of a loop of hot metal strip S between two stands of a rolling mill, the apparatus comprises a disc 3 having a number of slits (only one, 21, of which is shown), which is rotated in the path of radiation, from the strip, focused on to a detector 4, and also in the path of light from a source 5 directed towards a detector 6. The passage of each slit in the disc 3 past the detector 6, which may be a photo-diode, produces a reference pulse. The production of an output pulse from detector 4, which may be a photo-multiplier, occurs a certain time after each reference pulse dependent on the vertical position of the strips. To measure the interval between the two pulses, the outputs from the photo-multiplier 4 and detector 6, respectively are fed through amplifiers (7, 8) and pulse shapers (9, 10) to trigger circuits (11, 12) controlling a logic circuit of AND- gates (13, 14) and OR-gates (15, 16 and 17). The absence of an output from either OR-gates (15 or 16) causes a respective integrator circuit (18,19) to integrate. When an output is present, an integrator stores the previously integrated values. However, the presence of an output from an AND- gate (13, 14) causes resetting of the corresponding. integrator. Also provided are feedback loops from trigger (12) to trigger (11) to ensure that the triggers are in the proper states at particular instants in the measuring cycle. The integrators are arranged to operate alternately, one storing the measurement obtained in the previous measurement cycle during erasing and integration by the other. At any one time, the integrator which is storing produces an output from OR-gate 17, which is representative of the interval between the above-mentioned two pulses. The position of the end of an ingot or slab may be measured using apparatus similar to that described. Also, the frequency of vertical oscillation of the strip may be measured.

Title: Improvements in and relating to electric control systems for shearing and other machines
IPC: B23D36/00
Filed: 1937-04-29
Abstract: 484,754. Shearing & c. BRITISH THOMSON-HOUSTON CO., Ltd. April 29, 1937, No. 12264. Convention date, April 29, 1936. [Class 83 (iv)] In a machine for shearing or otherwise operating on a moving strip, means is provided for introducing an adjustable time delay, proportional to the speed of the strip, between the instant the bar contacts a flag switch 16 and the initiation of the shearing operation. The shear 12 is operated by a solenoid 13. Rolls 11 of the last mill stand are driven by an electromotor 14. A time-delay device 17 comprises a cam switch with an adjustable stationary contact 17d and a contact 17b biassed by a spring 17c, and rotated in accordance with the speed of the strip by a stator member 18a with a three phrase winding and a rotor 18b with a single phase winding wired to a similar receiving device 19. An electromagnetic clutch 20 connects the device 17 to the receiving device 19. The clutch 20 is energized by a relay 24. A relay 25 energizes the solenoid 13 of the shear mechanism, an interlocking time-delayed relay 26 preventing repeated operation of the shear when the flag-switch is depressed. Operation. When the flag switch 16 is up the interlocking relay is energized and its contacts closed. When the strip strikes the flag switch 16 contacts 16b are closed to energize a relay 24 to complete a locking circuit independent of relay 26 through contacts 24a. At the expiration of the time delay the relay 26 is de-energized. The relay 24 closes contacts 24b in circuit with the clutch 20. Since the device 19 rotates at a speed proportional to the velocity of the strip, the member 17b is similarly rotated from its zero position until the member 17b engages contact 17d to complete a circuit through relay 25 to close contacts 25b of a locking circuit independent of the device 17 and to open the locking circuit of relay 24. The contacts 24b in opening disconnect the clutch 20 and the member 17b is returned to zero position. In the closed position of relay 25 contacts 25c close a circuit through the operating solenoid of the shearing mechanism. After shearing contacts 13a, 13b are opened to open the circuit in relay 25. This opens contacts 25b, 25c to de-energize the solenoid 13 thereby resetting the shearing mechanism. When the relay 25 is de-energized contacts 25a are closed to partially complete the circuit for the relay 24 but no operation of the relay 24 occurs although the contacts 16b are closed because relay 26 is de-energized and its contacts open to prevent relay 24 being energized until the flat switch is restored to its normal position.

Title: Fuses for projectiles
IPC: F42C15/31
Filed: 1924-05-26
Abstract: 216,539. Pantoflicek, B. May 26, 1923, [Convention date]. Projectile fuzes. - Relates to percussion fuzes of the kind in which the striker is adapted to be released by a locking member when a fuze composition normally blocking the forward axial movement of the locking-member burns away after discharge, and consists mainly in the use of a spring or other force independent of the movement of the fuze for causing the forward movement of the locking-member as the fuze burns away, whereby the striker is left free from impediment to its forward movement on impact. As shown in Fig. 1, the firing-pin 1 is locked by a safety element 9, which bears against the fuze composition 3 in a perforated chamber 4. When this burns away, a spring 16 withdraws the safety element 9 from the firing-pin 1. In a modification of this, the fuze composition is surrounded by a sleeve of metal which melts as the combustion proceeds, and, in melting, releases the safety element. The Specification as open to inspection under Sect. 91 (3) (a), describes also two other fuzes. In one, Fig. 5 (Cancelled), the safety element is a centrifugal radial bolt 43, which bears on a fusible metal plug 45 against the end of the fuze composition 41 in the time ring 40; the fusible metal plug 45 may be omitted, and the bolt 43 made to bear directly on the fuze composition. In the other, Fig. 6 (Cancelled), the safety element is constituted by a fusible metal plug 54, which is melted away by the fuze composition 51 of the time ring 50. This subject-matter does not appear in the Specification as accepted.
