Patent GB-258422-A (GB)
Abstract: 258,422. Larkin, M. W. Feb. 19, 1926. Momentary-contact switches, mechanical.-In an electric ignition system for gas burners, a manually-operated switch-member, connected with a source of high tension current, is adapted, when operated, to continue to move by its own momentum over a series of contacts F connected with spark gaps adjacent the burners. In the form shown, the switch-member comprises a steel or other resilient metal strip E secured preferably at the base to a contact block E<2> so that it can be oscillated across the contacts F. The strip E is provided with a weighted head E<1>, which carries a screw E<5> to form with each contact F an adjustable spark-gap E' in series with the main spark-gap at the corresponding burner outlet. A stud E<11> for operating the switch member and for closing a switch c<3>, c<1>, controlling the high tension current, may be slidably mounted in a slot E' in the cover E<7> of the panel E<3> on which the contacts F are mounted, the switch-member being released from engagement with the stud E<11> at the same time as, or immediately before, the latter engages the spring arm c<3>. The stud E" may be returned, when released, by a spring. In other forms, a resiliently-mounted arm, or a spinning member is employed. The spark-gap at each burner outlet is formed by an insulated electrode H<1> and an electrode forming part of the burner. The electrode H' may be clamped by a screw H<4> in a stem H<3> secured by interlocking insulating collars H<5>, H<6> and a nut H<7> to the side C of a lamp casing. The switch-member may be connected with the gas cock.

Abstract: 1,068,185. Securing nuts against loss; anchoring screws to work; locking nuts; circlips. ILLINOIS TOOL WORKS Inc. June 23, 1964, No. 25920/64. Heading F2H. A nut 96 captive in a hole in a panel 16 has an end flange 102 which enters a receptacle 24 (containing a screw 48) when the nut, by means of a socket 94 in its head 90, is screwed down on to the screw to fasten the panel 16 to a panel or frame member 18 to which the receptacle is secured (with freedom for self-centring with regard to. the nut) by a cage 38 fixed by rivets or screws to the member 18. A ring 80 is loaded by a spring 88, both retained in a cup having a base 72 and two side slots 74, so that two lugs 84 on the ring top engage slots in the nut flange 102 to prevent the nut 96 working loose from the screw 48. Except when the nut is positively driven, rotation of the cup (and of the ring 80 keyed to it by two radial lugs 82 engaging its slots 74) is prevented by protrusions 76 on the cup bottom 72 engaging grooves in the underface of the screw head. Knurling 54 on its head prevents rotation of the screw with respect to the receptacle 24 and the edge of the latter is rolled over at 56 to hold the screw head. Two lugs 36 on the receptacle engage loosely in holes 46 in the fixed cage 38 so that the screw and receptacle are anchored against rotation. The screw 48 may have a multi-start thread. A resilient ring 114 capable of circumferential expansion, to be snapped over the flange 102, is located in a counterbore 116 in the panel 16 or member 18 and coacts with the flange 102 to retain the nut 96. Two bent springs 110, each secured in an axial groove 108 in the nut side, urge the loosened nut to the raised position shown. The depiction of the grooves 108 as in alignment with the lugs 84 is for illustration only and in fact the diameters on which these items lie are mutually perpendicular.

Title: Control apparatus for units which become ready for operation at irregular times

Filed: 1969-05-21
Abstract: 1294326 Electric selective signalling NATIONAL RESEARCH DEVELOPMENT CORP 29 June 1970 [21 May 1969] 26030/69 Heading G4H A. circuit for providing control signals for a plurality of slow-speed units which become ready for operation at irregular times and then operate in communication with a central high-speed unit on receipt of a control signal comprises a number of stations 10, 11 connected in a loop, at least one unit being associated with each station, each station having a gate circuit to receive an enabling signal from the preceding station and a ready signal indicating that the associated circuit is ready for operation, the circuit providing either an enabling signal for the next station if the associated unit is not ready for operation or a control signal if it is causing the associated unit to operate. When the unit associated with station 10 is ready to operate it provides a signal on terminal 12 enabling And gate 27. The enabling signal is received on the loop input terminal 21 from station 11, and station 10 sends it out again on terminal 22. This signal is inverted at 15 so that a "1" arriving at station 10 on terminal 21 and leaving it as a "1" on terminal 22 is inverted at 15 and circulates round the loop as "0" until it is again inverted at 15. It then circulates as a "1" allowing operation of each station in turn. The enabling signal applied at terminal 21 passes to gate 24 directly and also through delay 25 to produce a delayed output to enable gates 26 and 32. Gate 27 receives the ready signal 12 and the enabling signal on terminal 21, differentiated at 31. The gate output sets a flip-flop 28 to provide another input to gate 32 which produces, on terminal 14 a control signal initiating operation of the slow-speed unit. If the ready signal is not present at 12 the flipflop remains unset and gate 26 then passes the delayed enabling signal to the next station via terminal 22. Gate 26 is connected to the "0" output of flip-flop 28 and remains closed until the flip-flop is reset. When the high-speed unit has finished the work provided by slow-speed unit a signal is given on terminal 13 to reset flip-flop 28. This opens gate 26 passing a signal to terminal 22, which then circulates round the loop as described above.

In apparatus for preheating and charging cement raw materials of the type comprising serially - interconnected cyclone separators through which the material passes generally in counterflow to hot kiln gases, each waste gas conduit 12 between adjacent separators 4 and 5 is connected to the cover 38 of the lower separator 4, said cover being resilient enough to accommodate the movement due to heat expansion of the separator 4 and its waste gas conduit 12. The conduit and separator are fixed as by members 39 to platforms 37. The. conduit has a flange 42 and the separator cover 38 a short pipe 40 with a flange 41, said flanges being drawn together by screwed bolts 43. Initially there is a gap between the flanges equal to about half the expansion movement and tightening of the bolts closes the gap and bows the cover outwardly. During use of the apparatus, the cover bows inwardly by a corresponding distance to the position shown in double dotted lines in Fig. 3. Specification 710,236 is referred to.

The wire 101, Fig. 1, may be fed through a straightening device 112 and guides 102, 103 to intergeared flattening rolls 21, 25 driven by a pawl 15 actuated by a crankdriven link 10. The roll-spindles are journaled at one end in adjustable bearings and are tied at the other end by adjustable rods 30. The rolls produce tapering flattened portions connected by unflattened intervals. The wire is then passed through a guide 106 to crimping rolls 42, 43 which are intergeared with each other and with the flattening rolls. From the crimping rolls the wire passes through a yieldingly-supported guide 79 over a die 76, Fig. 10, and over a mandrel 85. A cutter 66, actuated by a cam and linkage, cuts out a short length of the wire, leaving rounded ends, the waste being blown clear by an air blast at 77.
