Title: Improvements in and relating to indexing mechanism
IPC: A24C1/04
Filed: 1933-05-22
Abstract: 404,911. Intermittent gearing; cams. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) May 22, 1933, No. 28482. Divided on 404,859, [Group VI]. [Classes 80 (i) and 80 (iii).] The shaft 7 is rotated step - by - step through 180‹ for each revolution of the driving- shaft 33, a disc 38 on the shaft 7 being provided with two diametrically opposite rollers 36, 37 engaging a cam track in a disc 35 on the shaft 33. The track is circular except for a projection 40, and has a by-pass 41. When the rollers 36, 37 are both in the circular part of the track the shaft 7 is held stationary, but when the leading roller 36 enters the projection 40 the other 37 enters the by-pass 41, as shown in dotted lines at 401, 411, 36<1>, 371. Further revolution of the disc 35 causes a symmetrical movement to take place, and returns the second roller 37 to the circular track in the leading position at 37<11> in place of the first one 36 which is now at 36<11>.
Patent GB-642430-A (GB)
Title: Improvements relating to rotary coal and like tipplers
IPC: B65G67/00
Filed: 1947-10-27
Abstract: 642,430. Rotary tipplers. BARKER & SON, ENGINEERS, Ltd., W. H., and BARKER, W. Oct. 27, 1947, No. 28601. [Class 78 (iv)] The frame a of a rotary tippler is mounted on idle rollers c (Fig. 1) and is held at each end from contact with driving rollers d by a shoe f on the frame which engages a lever g, pivoted at h and biassed by a roller i on a lever j secured to the same shaft k as a counterweight m. Thus a momentary rotation of the shaft k to cause the roller i to release the lever g, permits the frame a to rest upon and be driven. by the roller d, rotation continuing until the shoe f again engages the lever g. The shaft k is periodically operated to release the lever g, when a loaded truck is in the frame a, by an eccentric 7, Fig. 4, on the continuouslyrotating shaft e of the driving rollers d and connected by a link 6 to a member 4 loose on the shaft k and formed with ratchet teeth 5 engaged by a pawl 3 pivoted to a member 2 fast on the shaft k. Thus when the pawl 3 is allowed to engage the teeth 5, the shaft k is periodically operated. The tail of the pawl 3 is normally engaged by a stop 10, on a lever 8 pivoted at 9, to hold the pawl out of engagement with the teeth 5, but the lever 10 is moved to disengage the pawl 3 when a loaded wagon is in position in the frame a. The front wheels p of the wagon rest on a portion n, Fig. 2, of the rails b which is secured to a shaft o and biassed by a spring r so that an unloaded wagon will not depress it. When the portion n is depressed by a loaded wagon a lever t on the shaft o, and formed with teeth engaging a bevel wheel u on a shaft v, is moved to turn the shaft v so that a lever 15, Fig. 4, on the shaft engages an arm 14 on a fixed shaft 13 to turn a lever 12 connected by a link 11 to the lever 8, so releasing the pawl 3. Rotation of the shaft v also moves levers w connected by links x to place stops y, pivoted at z to the frame, against the front wheels p. In an alternative construction the members n are depressed by the rear wheels of the truck to rotate the shaft v, provided the front wheels have first depressed a further projection releasing a lock on the shaft.

Title: Improvements in or relating to circuit arrangements particularly for automatic telephone exchanges
Inventor: GALVIN JOHN LESLIE
IPC: H04Q3/42
Filed: 1962-07-25
Abstract: 971,178. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 25, 1962, No. 28608/62. Heading H4K. In a national dialling system (STD) such as is described in Specification 971,177, in which the dialling of a prefix digit gives acess to a switching centre embracing a number of subscriber exchanges, one or more routing selectors thereat are controlled from a register-sender by the transmission to a common control circuit of code signals, positive or negative potential, over a pair of wires, e.g. the speaking wires. When sufficient code digits have been received in the register-sender REG they are transferred to a common translator (not shown), which returns one, or if necessary two routing digits in a 2-out-of-6 code to operate pairs of relays AU . . . AZ, BU . . . BZ. Relay RK energizes provided the code or codes are valid and connects up SA, whereupon relay KL operates over wire M as long as the selector IRS is at home and the control circuit IRSC is available. Associating relay K pulls up over wire P. The code signals sent to the control circuit IRSC consist of four elements and the first according to the condition of AU . . . AZ energizes relay AP or AN, these relays being connected to the negative wire over opposed rectifiers MR1, MR2. Relay CO energizes in series and connecting up SX, so that the second element of the signal is effective over the positive wire to energize BP or BN. Relay GC operates and disconnects CO so that the third and fourth elements are sent respectively over the positive and negative wires to energize DP or DN and CP or SS, the latter relays being short-circuited until DP or DN energizes. Relay SS whether operated directly or through the agency of CP starts the selector IRS and prepares the test circuit. The selector seizes an idle trunk in the group marked over contacts of AP . . . DO, BN, DN, and relay SA falls back in the register-sender and connects the speaking wires to a loop-impulsing circuit L1A, L1B for the transmission of digital signals. If, however, a second routing selector is required, a pair of relays BV . . . BZ are operative and relay SB energizes at some stage. In consequence when SA falls back code signals are sent under the control of BV . . . BZ to set the second routing selector, and the loop-impulsing circuit is established when SB goes back.

Abstract: 978,772. Measuring electrically. UNITED STATES STEEL CORPORATION. Aug. 11, 1961 [Aug. 12, 1960], No. 29120/61. Heading G1N. Apparatus for measuring and recording the temperature of a load within a rotary kiln wherein the load piles up at an angular distance from the lowest point of the kiln comprises a plurality of temperature sensing elements spaced lengthwise and circumferentially of the kiln, a recorder which is connected successively to each of said elements in turn, and means actuated by the kiln for operating said recorder when each element reaches said angular distance from the lowest point of the kiln. As shown, a plurality of thermocouples 13, 14, 15, 16 are mounted inside the wall of a rotary kiln 10 containing a load M of fused material, e.g. cement clinker, the thermo-couples being spaced at equal angular distances around, as well as lengthwise of, the kiln. The outputs from the thermocouples are passed via rings 17.... 21, Fig. 1, insulatedly mounted on the outside of the kiln wall, stationary contact arms 22.... 26, and leads 27.... 31, Fig. 2, to contact studs 76.... 80 on the rotary switch 75 of a potentiometric recorder 32. In order that the recorder should print the output of each thermo-couple when the latter is overlaid by the load M, a timer 38 is set by a reversible drive unit 59 controlled by reversing relays 60, 61 in an amplifier 58. The input to the amplifier is the algebraic sum of the outputs of a D.C. energized bridge I comprising fixed resistors 39, 40 and potentiometer 41; a bridge II energized by the output of a D.C. tachogenerator 45, driven by the kilndriving motor 12, and comprising fixed resistors 49, 50 and a potentiometer 51; and a D.C. energized potentiometer 54 which is automatically adjusted by drive unit 59 to maintain the said algebraic sum at zero. Potentiometers 41, 51 are manually set to determine the angular distance from the lowest point that a thermo-couple will have reached when the recorder operates, variations of the speed of rotation of the kiln being automatically compensated by bridge II. As each thermo-couple reaches the lowest point a shoe 33.... 36 on the kiln wall actuates a switch 37 to start the timer running. When the latter times out contacts 71 open to disconnect a capacitor 90 from one of two A.C. lines 62, 63, and contacts 72 close to discharge the capacitor 90 through a resistor 91. When the timer resets, contacts 71 close and the capacitor recharges, energizing a relay A which operates to bring up a relay B, thus de-energizing a "print" solenoid 93 to cause a pen 94 to record on chart 95 the temperature represented by the voltage connected via a rotatable element 81 of rotary switch 75 to the measuring circuit (not shown) of the recorder. De-energization of solenoid 93 also closes a switch 96 to cause solenoid 97 to advance the rotatable element 81 one step through gear and ratchet mechanism 98.
