Abstract: 757,758. Sliding jaw clamps. BELLING & LEE, Ltd. May 31, 1955 [June 16, 1954], No, 176,95/54. Class 44. [Also in Group XL (c)] A mounting arrangement for a rigid folded dipole aerial element comprises an insulator 10 provided with collinear recesses 11 into which the ends 12 of the element are fitted and secured by bolts 13 provided with wing-nuts 14. The insulator has a recess 15 shaped to fit the mast and, on either side of the recess, pockets 16 to receive the ends of the limbs 17 of a strap member 18 which surrounds the rest of the mast. The strap member is also provided with recesses 19 to receive the uninterrupted arm 20 of the element. The arm 20 is secured in place by clamping brackets 21 which fit slidably into recess 22 in member 18. The mounting is held in place by a bolt 24 passing through a hole in the insulator, a co-operating hole in the mast and a hole in the member 18 allowing it to be threaded into a nut 23 in recesses 25 provided in the brackets 21. On tightening the bolt both the mast and arm 20 are securely gripped. The mounting is assembled by first fixing the insulator and then springing the strap member and brackets into place so that they are retained by the resilience of the aerial element until the mounting is in place on the mast and the securing bolt can be fixed. Wing nuts 14 serve as terminals for the connection of a feeder.

Title: Methods of and apparatus for measuring properties of materials
IPC: G01H15/00
Filed: 1974-10-24
Abstract: 1481698 Measuring hardness KRAUTKRAMER GmbH 24 Oct 1974 [15 Nov 1973] 17846/74 Heading G1G A contact impedance method of measuring physical properties of materials e.g. modulus of elasticity, Poisson's Ratio and hardness using an ultrasonic transducer excitable at its resonant frequency is described. Magnetostrictive transducer 1 is energized by an exciter circuit 2 which, by means of coils 3, 4, causes the transducer to vibrate at its resonant frequency. A mechanical switch 6 determines whether or not the transducer indenting tip 5, of e.g. diamond, is in contact with specimen 9. Control unit 8 receives a signal 7 indicating whether the former or latter condition obtains. When transducer 1 is not in contact with the specimen 9, up/down counter 11 is gated by variable gater 13 to measure the transducer frequency. The count at the end of the gate signal is proportional to the frequency. A scale adjustment is provided by unit 14. Control unit 8 controls; by signal 15, the gate signal repitition frequency; by signal 16 the counting direction of up/down counter 11; signal 17, erasure of the counter contents; signals 18, 21, the data flow between counter 11 and store 19. At the end of each count store 19 stores the counter 11 output. Before the hardness measurement, counter 11 counts the frequency of the freely oscillating transducer, counting in the down direction, and repetitively, under the control of the gating signal, the measured value constantly up dating store 19. To perform the hardness measurement, the indenter 5 is brought into contact with specimen 9 by constant test load 27. Counter 11 is pre-set to the last zero measurement counted as stored in store 19 and counts upward at the new resonant frequency of transducer 1. The difference count remaining in counter 11 is used to address ROM 23 which provides a preprogrammed output signal to indicator 25, and may employ different hardness scales e.g. Rockwell or Vickers.

Title: Improvements in or relating to combustion supervision systems
IPC: F23N5/08
Filed: 1968-04-16
Abstract: 1,212,246. Controlling burners. ELECTRONICS CORP. OF AMERICA. 16 April, 1968 [28 April, 1967], No. 17852/68. Heading F4T. [Also in Division G1]. In a burner control and supervision system including a radiation detector and flame sensor 10 of the avalanche discharge type sensitive to ultra-violet radiation the circuit arrangement includes an integrating circuit which energizes a combustion condition indicator in response to the average value of a pulse train from the flame sensor exceeding a predetermined threshold value and a circuit responsiveto the integrating circuit to de-energize the indicator when the average value of the pulses remains below the predetermined value for a predetermined time. Radiation from the flame 14 of a burner 16 having its fuel flow controlled by a solenoid valve 20 connected to a flame relay 24 causes a sensor 10 to transmit short pulses to a transformer 30 which converts them to low voltage high current pulses which are rectified by diodes 32, 34 and fed to a network including a transistor 42, the output pulse of which charges a capacitor 50 in an integrating system including a threshold transistor 62, the collector 72 of which is connected through a resistor 74 to a second integrating circuit including transistors 82, 84 which constitute a bi-stable circuit for energizing the flame relay 24, the coil of which is connected in the collector circuit of transistor 84. In operation, when pulses are produced by the sensor 10 with sufficient frequency to indicate a flame, the capacitor 50 becomes charged to a potential higher than the threshold produced by resistor 66 and transistor 62 becomes conductive and passes current to charge a capacitor 76 at a rate determined by the resistor 74 until the voltage is sufficient to switch transistors 82, 84 into conduction and thus energize the relay 24 and open the main fuel valve 20.

Abstract: 952,179. Stripping cables and conductors. LUMALAMPAN A.B. May 20, 1960 [May 23, 1959], No. 17909/60. Addition to 931,338 as improved upon by 932,321. Heading H1A. [Also in Division B3] In apparatus as claimed in Claim 1 of the parent Specification, the knife and stripping element(s) 30 are mounted for rotation about the cable or the like on supporting arms 28 on a first rotatable element 32, and pins 70, provided on a second rotatable element 33, rotatable about the same axis as the first and capable of rotational angular displacement from the first, engage in slots 71, provided in the supporting arms 28. The supporting arms 28 are pivoted on opposite sides of the first rotatable element or pulley 32, and the pins 70 are connected at their ends remote from the second rotatable element on pulley 33 by a bar 73 (shown dotted in Figs. 1 and 2) provided with a hole 74 for the passage of the stripped wire. The pulleys normally rotate together clockwise with the knife jaws open (Fig. 1), a braking action however, applied to the pulley 32, causes it to drop back with respect to pulley 33, with the result that the pins 70 travel along the slots, pivoting the arms 28 and closing the knife jaws (Fig. 2). Bolts 72 limit the jaw closing movements of the pins. Centrifugal force opens the jaws once the braking action is removed. In a modification the pins 70 may be fixed to the arms 28 and engage slots in the pulley 33.

Title: Power source checking device
IPC: G01R31/36
Filed: 1974-04-24
Abstract: 1465358 Voltage monitoring ASAHI KOGAKU KOGYO KK 24 April 1974 [26 April 1973] 17953/74 Heading G1U If the voltage of a source, for example battery 3, is above a threshold level a transistor 8 conducts and a light-emitting diode 1 is held off, the current through it being maintained low by a high resistor 2. However if the voltage falls below the threshold level, transistor 8 becomes non-conductive, transistors 4 and 6 become conductive, thereby shunting resistor 2 by a relatively low resistor 7, and the light-emitting diode is lit. Shunting of resistor 2 reduces the voltage on the base of transistor 4 thereby reinforcing the switching action of the differential pair 4, 8. By not employing a Zener diode, the circuit is said to be more easily integrated, and temperature compensation in respect of the light-emitting diode 1 is provided by a second diode 12.

Abstract: 421,890. Washing coal. MINERALS SEPARATION, Ltd., and WILLIAMS, P. T., 62, London Wall, London. June 27, 1933, No. 18321. [Class 82 (ii)] In a coal washery in which the coal is washed in jigs, trough washers, or other wet gravity separating apparatus, and the washed coal is passed over screens for separation of the water, the whole or part of the water passing through the screens is subjected to froth flotation to separate the fine coal, and the bulk or part of the tailings water from the flotation plant is passed to a settling tank from which the clarified water is returned to the washery. When part only of the water from the screens is to be treated, the remainder is returned direct from the coal screens to the jigs. The coarse particles may be separated from the water passing through the screens, e.g. by settling, before the latter is subjected to the flotation treatment, and the flotation concentrates may be subjected to one or more further flotation treatments. In the form shown, washed coal from jigs 11 passes on to screens 12 from which the water drains into a small settling tank 13 in which the coarse particles settle. The overflow from the tank 13 passes to a flotation apparatus 14 which preferably comprises one or more large boxes suitable for the treatment of dilute pulp. A small amount of frothing agent, e.g. cresol, is added to the pulp, and the small coal removed as a froth concentrate, which may be retreated one or more times in smaller cells 16. Fresh water is added to the last of the retreatment cells, and the tailings water from this cell is taken to the preceding cell, and so on, the tailings water from the first retreatment cell being returned to the jigs. The whole or part of the tailings water from the main flotation cell 14 is passed to a clarification vessel 17 where the clay slimes settle, the supernatant water being drawn off at 27 and returned to the jigs. If only part of the tailings water from the cell 14 is passed to the vessel 17 the remainder is returned direct to the jigs. The fine coal concentrates from the flotation treatment are passed to a dewatering apparatus 20 or to the coal screens 12. The coarse particles settling in the small tank 13 may be treated by a classifier 18 or tables or flotation apparatus, the coal recovered being passed to the dewatering apparatus 20 or the coal screens 12, and the tailings passed to a dewatering apparatus 19 and then to waste, the water from the apparatus 19 returning to the jigs. Specifications 122,454, 215,841, and 240,799, [all in Class 82 (ii)], are referred to.
