Abstract: 1,021,817. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 22, 1962], No. 41240/63. Heading H4K. An electronic system acting on the selfseeking principle as described in Specification 953,895 provides for PBX hunting by the use of a control circuit for each group which is taken into use when the line called by the directory number is busy to effect the selection of an idle line from the other lines of the group. Line circuit, Fig. 2. This is somewhat similar to that described in Specification 1,021,816. In the normal condition, transistor 206 is switched on, while transistors 207, 208 are switched off. When a call is initiated, the change of potential on wire 230 switches on 207 which in turn switches on 208. The potential at P3 is clamped to that on wire 43 which is removed when an idle link is allotted. It then becomes that of the collector of 207 and a firing pulse controlled by capacitor 218b is passed to point X to effect switching. The switches are held by way of resistors 217, 216, 224 and 208 is switched off. If no switching path is established, 208 remains on and a further attempt is made during the next allotting interval. Assuming that a path is established, dialling switches 207 off and on to change the potential at P3. When the line is called, a ground marking on T, U switches 206 off, and in consequence 208 is maintained off but 207 is switched on. The potential at P3 is now such that a firing pulse controlled by capacitor 218a is applied at X to effect switching. 206 switches on again when the marking is removed and switches off 207, but this is switched on by the reply of the called subscriber, and its off condition gives a release signal when the subscriber goes onhook. If the line is busy, the switching off of 206 produces no change sufficient to generate a firing pulse since 207 is already on. Group controller, Fig. 3, for sequential hunting. Terminals A of the line circuits other than the first are connected to transistors such as T39. When the first line L31 is called and is found to be busy transistor T5 operates and a ring counter steps under the control of an oscillator T31, T32. In consequence, transistors such as T39 which are normally operative are switched off in turn to control transistors 206 of the corresponding line circuits, the action continuing until an idle line is found. Group controller, Fig. 4, for random hunting.- Terminals B of the line circuits are connected over individual resistors to transistor T42 and terminals A to transistor T41. When a particular line is called a negative-going pulse fires T42, and, after a delay produced by a capacitor 428, T41 switches off, whereupon if the called line circuit has not already done so, the remaining line circuits race to fire through the switching network. Other embodiments are described, Figs. 5, 6, 7 (not shown), in one of which the hunting is partly sequential and partly random.

Abstract: 157,138. Smith Engineering Works, (Assignees of Smith, T. L., and Sanborne, E. L.). Nov. 6, 1916, [Convention date]. Crushers with gyratory heads.-Relates to a gyratory crusher and consists in providing means for adjusting the hopper in order to move the crushing-concave nearer to or farther from the crushing-head to alter the size of the product, means being provided, also, to prevent lateral play between the concave and the central shaft. The machine comprises a lower section 10 and an upper section 11 which is provided with a crushing-concave 12 of the type which flares downwardly, the central shaft 14 being supported by spiders formed integrally with the sections 10, 11. The crusherhead 16 rests on a flat bearing-ring 17, and an eccentric sleeve 18, fitting within the bor.e of the crusherhead, rotates on the shaft 14 and is driven by a shaft 21 through bevel gears 19, 20. The upper section or hopper 11 rests on jack screws 28 threaded in a flange 29 of the lower section 10. Thus by adjusting these screws, the upper section 11 may be raised or lowered and the concave 12 moved nearer to or farther from the crusher-head. Distance plates 30 may be placed between the flanges, bolts 31 being used to clamp the sections together. The upper section 11 has an annular skirt 22 fitting within a flange 23 of the lower section and having a tapering outer face. A wedge-ring 24 is wedged securely between the skirt 22 and the lower section by means of screws 25, thus preventing lateral movement of the upper section in any adjusted position. Similarly, a tapered bushing 83 is wedged between the conical upper end of the shaft 14 and the hub in the upper spider. In order to lubricate the sleeve 18, the shaft 14 has an axial bore and radial openings 46, and lubricant is supplied to the shaft by a pump 42 through a pipe 45. To prevent grit from reaching the wearing parts and to prevent the escape of oil, an oil ring 50, which fits with a groove 51 in the upper spider rests on the upper part of the crusher-head and is pressed against it by screws 52. an inner lining of filtering-cloth 8, and an open bottom. The moisture is pressed out of the peat by rollers 11 carried upon arms 12 and the peat is loosened from the sides of the bowl bv cards and vertically oscillated scrapers and is continuously removed from the bowl by scaling pipes 10.

Title: Improved fuel burner control apparatus
IPC: F23N5/08
Filed: 1960-01-11
Abstract: 936,734. Photo-electric burner control. MINNEAPOLIS - HONEYWELL REGULATOR CO. Jan. 11, 1960 [Jan. 13, 1959], No. 1016/60. Class 40 (3). [Also in Group XI] An electronic flame detector and monitoring arrangement for a fuel burner is arranged so that the detector is automatically checked each time the burner is put into use. A two-stage discharge tube circuit is used having an input tube 11 and output tube 12. A photo-cell 13 views the burner 34. With an energizing supply coupled at 40, 41, operation of switch 42 makes the burner ready for use and capable of automatic control by bi-metallic strip 22. Closure of switch 42 supplies output tube 12 but not tube 11 with anode voltage. A potential is applied across photo-emissive cell 13 which in the absence of a flame is non-conductive. Under these conditions the input circuit simulates " flame present " conditions, tube 12 conducts, and relay 16 is energized. This relay applies a supply voltage to the anode of tube 11 from transformer 44 and energizes relay 32 to maintain this supply regardless of the position of relay 16. When tube 11 is fed with its supply voltage the potential across resistor 14 cuts off tube 12 to release relay 16. This concludes the checking sequence and any subsequent closure of bimetallic strip contacts 22 completes a circuit for relay 23 which controls the opening of a valve 38 in the fuel supply to pilot burner 37 and operates ignition device 39. If the pilot burner fails to light, heater winding 30 opens safety switch 27 after a suitable time interval, thus releasing relay 23. If a flame is produced this renders cell 13 unidirectionally conductive and produces charges on capacitors 56 and 83 rendering tube 11 non-conductive. When this occurs there is no voltage drop across resistor 14 and tube 12 conducts to operate relay 16. The contacts of this relay then function to disconnect the ignition device, open the main fuel valve 36, and open the circuit containing relay 23 and heater winding 30. Any subsequent extinction of the flame will cause relay 15 to be released and a sequence of events resulting in re-ignition or the opening of safety switch 27 to cut off the fuel supply.

Abstract: 659,799. Pulse frequency dividing circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 15, 1946, No; 1314. [Class 40 (vi)] In a circuit of the type in which a stepped waveform is generated under the control of input pulses to operate a triggered device, the input pulses are also applied to the triggered device to improve the timing of the output pulse. Each positive pulse applied to normally non-conducting valve V1 causes the anode potential to fall, capacitor C1 discharging over diode V2 so that upon the pulse ceasing the anode of diode V3 is carried positive, thus charging capacitor C2 from capacitor C1. When valve V1 conducts the input pulses appear across cathode resistor R3 and due to coupling resistor R2 are superimposed on the stepped waveform developed across capacitor C2, Fig. 2 (not shown), and applied to the grid of blocking oscillator V<SP>1</SP>1. Valve V<SP>1</SP>1 is thus triggered by the leading edge of an input pulse after a sufficient number of steps have been developed across capacitor C2. A similar circuit is used in the next dividing stage. Alternatively, the input pulses may be fed directly to the second stage. Specification 471,731 is referred to.
