Title: Improvements relating to the removal of material from a heap or pile thereof
IPC: B65G65/06
Filed: 1940-03-02
Abstract: 537,095. Piling and reclaiming materials; conveyers. ROSS, W. March 2, 1940, No. 3971. [Classes 78 (i) and 78 (iv)] Materials such as stones, coal, or ore are removed from a pile by causing means to traverse a face of the pile, for example a flank or an end face, to displace the surface material in an upward direction and on to means for carrying the material away from the pile. In the apparatus shown, a flank of the pile 1 is traversed by the lower run of a conveyer 8 and the material displaced to the top of the pile slides down the other side on to a discharge conveyer 6 in a pit 7. The conveyer 8 is provided with scrapers 12 and is pivoted at 9 on a wagon 13 travelling on rails 14 and provided with a winch 16 and rope &c. 15 for raising and lowering the conveyer. A second conveyer 17 may be provided at the other side of the wagon for operating on another pile of material. The pile 1 is formed by material carried by a conveyer 2 on a tripper car 3 to a drum 4 and deposited on a conveyer 5 discharging it on the pile. In a modification, the end face of the pile is engaged by a conveyer on a wagon travelling on rails at the sides of the pile, and the material slides down the sides on to a discharge conveyer such as 6 at each side.

Filed: 1977-02-01
Abstract: 1528721 Ionization smoke sensors CERBERUS AG 1 Feb 1977 [6 Feb 1976 (2) 14 Oct 1976] 03997/77 Heading G1N [Also in Divisions G4 and H 1] A fire sensor includes both a bipolar ionization gauge and a unipolar ionization gauge connected to an evaluation circuit which initiates an alarm condition when the resistance of at least one of the chambers exceeds a predetermined threshold. By using two chambers smouldering fires are detected and the effects of air speed are mitigated. The unipolar chamber U, see Division H1, comprises a grid housing, which gives unhindered access to air, provided with a radio-active source which has a range and so positioned and/or screened that bipolar ions are generated only within a limited area of the chamber the remainder only including ions of one polarity. The bipolar chamber B on the other hand comprises a radio-active source mounted in a housing substantially impermeable to air but through which air can enter only after being retarded and deflected whereby ions of both polarity are generated throughout the housing. Each chamber may be connected in series with a resistor across supply lines with the junctions therebetween connected to a threshold circuit Fig. 4 (not shown) or as shown in Fig. 6 to a reference chamber R, the junctions being connected to the gates of FET's T I , T 2  which are connected to an OR gate and switch S (thyristor) to generate an alarm signal. The three chambers may be continued into a mechanical unit Figs. 7, 8 (not shown). The sensor may be connected to control the frequency of an astable multi-vibrator Fig. 9. In the absence of smoke the frequency of the multi-vibrator is such that the charge on capacitor 16 is sufficient to keep transistor 18 ON whereby relay contacts 20 are kept open. If the resistance of either of the chambers increases due to smoke the frequency falls and the charge on capacitor 16 falls and transistor 18 switches OFF whereby relay 19 releases and contacts 20 close to operate an alarm.

Title: Improvements in yarn delivering devices for textile machines, and in particular for twisting frames
IPC: D01H13/18
Filed: 1955-02-10
Abstract: 776,199. Yarn delivering devices; delivery stopping. BREVETS AERO-MECANIQUES SOC. ANON. Feb. 10, 1955 [Feb. 25, 1954], No. 4033/55. Class 120 (2). A yarn delivery device in which yarn is fed between a driven cylinder and a pressure roller and the yarn after passing between these two elements is engaged by an outlet guiding element carried by a movable member arranged in such a manner that when the tension in the yarn ceases to exist the member is automatically displaced, preferably under the action of its own weight, an inlet guiding element being mounted in such manner on the movable member that when the latter moves the yarn is brought into a groove in one of the two elements forming the delivery means thus stopping the feed of the yarn, is characterized in that the said groove has a relatively small slope such that after piecing up the yarn automatically returns to the active zone of the delivery elements. As shown the invention is applied to a doubling machine including a driven feeding cylinder 1 and a pressure roller 2. A pair of single yarns f passes through an inlet guiding element 3 on a pivoted member 6 and then between the cylinder 1 and the roller 2. The composite yarn f1 passes through the outlet guide 4 on the other member of the pivoted member 6. The member 6 is so arranged that when there is no longer tension in the yarn f1 (due for example to yarn breakage) the member 6 automatically comes into a position (as shown on the left hand side of Fig. 2) such that the inlet guiding element 3 brings the yarns f opposite a groove 8 in roller 2 thus stopping further delivery of the yarn. After piecing up the resumed tension of the yarn compels the member 6 to swing back into a position in which the yams are moved away from the groove 8 (full line position on right hand side of Fig. 2) and due to the small slope given to the side of the groove 8 the yarns slide out of the groove without further risk of breakage. The inlet guide 3 may be reciprocated in the normal manner by a reciprocating bar 10.

Abstract: 881,802. Measuring electrically. MELCHIOR, F. C. Feb. 5, 1960, No. 4206/60. Class 40 (1). In a transducer in which the value of a physical variable is electrically signalled by a means responsive to the relative motion between a sensing element and a part movable under the influence of the variable being measured, the sensing element is spring mounted by a spring of such a rate that, when the transducer is subjected to acceleration forces, the deflections of the sensing element and the part movable under the influence of the variable are equal; there being no relative motion other than that due to changes in the variable being measured. In the altimeter of Fig. 2 barometric capsules 28 control the position of the armature 34 of a differential transformer type pick-off the output of which maintains the windings in the position of zero output by means of a screw and nut mechanism 74, 76 and drives an indicating tape. The windings of the differential transformer are mounted in the sleeve 76 by a spring 86, Fig. 5, in the form of a slotted disc, the arrangement being such that in response to any given acceleration the armature and coils of the pick-off move to the same extent. Also provided in the drive to the indicator tape is a differential gear driven from a knob on the front panel of the instrument so that, with the aid of a second indicator tape driven directly by the knob the main altitude reading may be manually corrected for variations in ambient barometric pressure. Specification 774,844 is referred to.

Abstract: 538,892. Type-bar-making machines. CLEMO, L. M., [Representative of CLEMO, F. A.]. (Mergenthaler Linotype Co.). March 8, 1940, No. 4408. [Class 100 (iii)] Ejecting type-bars. The width of the ejectorblade is automatically adjusted in accordance with the length of the selected mould by means carried by the mould-disc and brought into action during the rotation of the disc for effecting a change of mould. A number of ejectorblade sections 30, Fig. 2, appropriate to a particular mould is, as heretofore, selected by a vertically sliding bar 34 operated by a lever 58. When the mould-disc turning-pinion 11, Fig. 3, is drawn forwards to disengage it from its driving-mechanism, it acts through a spring- controlled lever 40, intermediate connections, and the lever 58 to move the bar 34 into its lowest position, which corresponds to an ejector of minimum width. The'lever 40 carries a sliding spring-pressed plate 65, Fig. 4, which is normally held in adjusted position by a latch 68 engaging ratchet-teeth 69. The movement of the lever 40 carries the plate 65 into line with an abutment 72 on a lever 73. A fixed cam withdraws the latch 68, and the plate 65 is moved by its spring into contact with the abutment. The position of the abutment is determined by a series of blocks 80, one of which is located at the end of each mould. On rotation of the pinion 11 to select a new mould, a different block 80 is brought into position, and acts through the lever 73 to adjust the slide 65. When the pinion is reengaged with its driving-mechanism, the initial movement of the lever 40 allows the latch 68 to lock the slide 65 in its adjusted position. The slide has an inclined portion 84, Fig. 7, which by encountering a fixed stop 66, limits the return movement of the lever 40. The degree of movement of the lever, and, consequently, the distance through which the ejector selecting-bar 34 is raised, are thus determined by the setting of the slide 65.
