Abstract: 412,806. Metal wall-studs, girders, and like structural members. BUELOW, G., 15420, Archdale Avenue, Detroit, and BUELOW, H. W., 2013, Northwood Avenue, Royal Oak, both in Michigan, U.S.A. Sept. 16, 1933, No. 25707. Convention date, Aug. 12. [Class 20 (iv).] A metal wall-stud, joist, girder, or like structural element is formed in the body of the element with a pair of laterally-spaced slots 38 for receiving and bending nails driven thereinto for the purpose of securing material to the element. The element may consist of two channel members 20 with an intermediate hollow member 22 disposed between such members to provide the nail-receiving slots 38 as shown in Fig. 2. The members 20, 22 may be inwardly or outwardly curved, and in the former case the inwardly curved faces of the member 20 may be welded together. The channel members 20 are provided with bosses 40 adapted to be welded or otherwise secured to the intermediate member 22. Boards or sheets 44, 48 are secured to the metal unit by nails 46, 50 which are driven into the slots 38 and take up the curved form of such grooves. A half-unit may be formed as shown in Fig. 5 of two angle members 54 with an intermediate hollow member 52, and such a unit may be employed as the upper and lower members of a lattice girder as shown in Figs. 6 and 7, the lattice members 76 then being of channel form and adapted to be fitted between, and welded to, the edges of the upper and lower hollow members 52<a>. Each of the upper and lower members of such a lattice girder may, alternatively, be formed from a single metal strip 82, the outer edges of which are bent as shown at 90 in Fig. 12, and the nail-receiving slots being formed between such portions 90 and portions 102 slit and bent from the central portion of the strip 82. In a modified form of this girder, shown in Fig. 13, the upper and lower members each comprises three portions, viz :-two angle members 88<a>, and a facing member 86<a> provided with bent portions 102<a> and having its edges 82<a> bent over the edges of the angle members 88<a>. In a further modification, a girder is built up of upper and lower members with a sheet metal connecting web, and the parts constituting the upper and lower members are connected by transverse ribs formed on such members instead of by bosses 40.

Title: Improvements in and relating to sliding windows, roof-lights, ventilators, shutters,doors and the like
IPC: E06B3/46
Filed: 1944-12-27
Abstract: 601,228. Door-operating mechanism. SMART, G. R. Dec. 27, 1944, No. 25880. [Class 65 (i)] [Also in Group X] In a sliding door &c. having at least two skins, each skin comprising at least two panels (1, 2 and 3, 4 in Figs. 2 and 3) which are cross-coupled to form two pairs of movable panels (1, 4 and 3, 2), operating mechanism is provided to move the lights in each pair simultaneously and in opposite directions. This operating mechanism may be selective so as to move each pair of panels independently of the other. In the example shown in Figs. 2 and 3, which is described with reference to windows (see Group X), the panels slide horizontally and are cross-coupled in pairs by means of pulleys and cables. The operating mechanism selectively drives panels 1 and 3 by means of chains 23 and 19 (Fig. 62) passing over sprocketwheels 24 and 20, and connected by further pulleys and cables to the driven panels. The sprocket-wheels 20 and 24 are mounted on independent shafts 30 and 31 connected by chains and further sprocket-wheels with clutch members 27, 26 respectively, freely mounted on a shaft 25 rotated by an operating handle 15. Between the clutch members and engageable selectively therewith for operation of one or the other pair of panels, is a dog 28 splined on the shaft 25 and slidable thereon by a fingerpiece 34 which rotates a shaft 33. A follower 36 on the shaft coacts with a cam 37 and moves the shaft 33 axially, the clutch shifter 32 being correspondingly moved. In a modification, vertically sliding panels are similarly coupled, except that the lower ends of each pair of coupled panels are connected by chains passing over sprocket-wheels, and the coupling means are arranged on both sides of the panels. These sprocket-wheels are connected by further sprocket-wheels and chains to worm-wheels 64, 65 (Fig. 47), each of which is thus adapted to operate one pair of panels. In this case, the operating mechanism comprises corresponding worms 66, 67 respectively, which are freely mounted on a shaft 68 rotated by the operating handle 15, the shaft having two splined portions 69 and 70 adapted to engage selectively the worms 66 and 67, on moving the shaft endwise by means of the handle 15. Other arrangements of -panels are described and illustrated in which, e.g. more than two panels may be operated simultaneously by the same operating mechanism (see Group X). The operating mechanism may include a slipping clutch to prevent over-run, and the panels may be operated by remote control and actuated by a motor instead of by hand.

Title: Improvements in targets for small arms practice
IPC: F41J7/04
Filed: 1919-10-23
Abstract: 156,931. Fenton, C. Oct. 23, 1919. Targets.-In targets for small-arms practise of the type in which the target, which is normally vertically disposed, is horizontally pivoted and adapted to move back and disappear under the impact of the bullet and afterwards return to its usual position by the action of a spring &c., the target is primarily balanced, so that it remains in any position in which it comes to rest, and is provided with a forward arm which moves upwards when the target moves back or " drops " behind a mantlet. The balanced target A is shown as arranged with three target plates, one of which, or its frame, constitutes the forward arm. The coiled spring k is attached to the forward arm by means of an eyelet m and to a fixed part by means of a cord p, having such an amount of slack that the target moves back through a certain distance before the spring acts. A detent mechanism is provided to position the target in its vertical position. When the target, on being struck, moves back, a finger E presses forward a spring-controlled pawl f<4> carrying with it the detent frame F until the finger rides over the pawl, after which the detent frame returns to its normal position by means of the springs G. When the target is returned by means of the spring k, the finger E rides over the pawl and comes to rest against an abutment f<3>. A dashpot M is provided. The Provisional Specification states that the construction and mounting of the three target plates are described in Specification 129,821, and that the detent mechanism may be of the same construction as that described in that Specification, but arranged in the reverse way.

IPC: F23Q3/00
Filed: 1967-05-24
Abstract: 1,220,925. Burner control systems; igniters. BABCOCK & WILCOX Ltd. 24 May, 1968 [24 May, 1967; 7 June, 1967], Nos. 24264/67 and 26236/67. Headings F4F and F4T. In a gas burner ignition and monitoring system comprising a capacitor 13 charged via a diode 11 from the secondary winding of a transformer 5 and discharged through the primary of a high-tension coil 9 to produce alternating spark discharges between an electrode 1 and a burner barrel 2, the flame is monitored by detection of a potential difference developed across a resistor 30 due by rectified ionization current between the electrode 1 and burner 2 and, to prevent false " flame-on " induction during spark generation, a potential difference of opposed polarity to that monitored is applied to the resistor 30, which potential difference is derived from the alternating spark current via a diode 33. The discharge of the capacitor 13 is controlled by a thyristor 14 actuated by a neon discharge tube 15 which is controlled by a reed relay 21. This discharge initiates a train of oscillations which cease when the neon tube 15 de-ionizes, the capacitor 13 then being recharged from the transformer 5. The ionization current causes a point 81 in the circuit to become negative to earth. This point 81 is connected via a filter circuit 42 to the gate of an N-channel field effect transistor 43, and when negative blocks the transistor 43 which in turn blocks transistors 54, 61 to cause a terminal 63 to assume a positive potential. This contact 63 being connected via a resistor 62 to a positive line 52, when a flame is not present, the point 81 has earth potential and the transistors 43, 54, 61 conduct to cause the terminal 63 to assume earth potential. The terminal 63 is connected to an indicator or other control apparatus (not shown).

Abstract: 302,434. Steinbach, K. Oct. 6, 1927. Hollow-ware.-Covers for cigar, cigarette &c. cases formed by pressing and punching them to shape and then turning up the fastening elements, spring band suspension eye, closing spring fixing flaps and hinge flaps, are completed by folding inwards the upstanding rim portions to form the bevelled edge and shearing the inner edge of the bent over material. The cover a, Fig. 4, having hinge flaps a<2>, fastening elements a<3>, suspension eye a<4>, and closing spring fixing flaps a<3>, is placed on an angular carrier c, Figs. 1 and 2, of a press with a V-shaped ram d the face of which is spaced away from the rim of the carrier by the thickness of the metal of the rim a<1> to be bent inwards; during the bending operation the cover is held down on the carrier by a second ram e under pressure of springs e<1>. The bent over edges are then sheared to correct shape, the irregular edge with the lugs a<3>, a<4>, a<5> by a profile cutter blade g, Fig. 7, and the plain edges by the cutter h, Fig. 9. The counter cutters of the blades g, h are formed on a bridge i on the base k, the edge of the bridge merging into a rule l on which the bent over edge of the cover is hung. The base has a cut-out portion k' for passing the cover up into position. The hinge flaps a' are bent slightly inwards at the ends a<2> and bent to circular form by a bending ram m, Fig. 10, with a transverse groove m', the opposite side of the base n being provided with a stripper hook o. For covers with all four edges bent inwards a bed p, Fig. 13, for the hinge is pressed in the rear edge by a ram s on a head u provided also with a hold-down spring-pressed ram t. The base on which the cover is supported during this operation consists of a central part q with inclined faces q<1>, Fig. 12, and two correspondingly shaped parts r supported by springs r<1>.

Abstract: 1513945 Measuring force P FISCHER 23 June 1975 [26 June 1974] 26518/75 Heading G1A In a device for measuring a force applied via a knife edge 17 to one end of a beam 14 which pivots about a further knife edge 13, the displacement of one end of the beam from the "null position" is monitored by a combination of a light source 47, Fig. 2, and two series connected phototransistors 45 and 46. The current originating from the transistors 45 and 46 is proportional to the amount and direction of displacement of the end 19 from its null position. The current passes via an amplifier 34 to a pair of coils 42, 43 (or 22, Fig. 1) attached to the beam. Under the influence of a permanent magnet 28 with a soft iron core 30, the core 42 produces a restoring force which strives to return the beam 14 back to its original position. The current also flows through a further compensating coil 36 which is wound around the outside of the permanent magnet 38. The compensating coil 36 is constructed and positioned so that its magnetic field causes the relationship between the current and the restoring force to be kept linear. At equilibrium a voltage proportional to the current can be tapped off across a series connected resistor 37. An oppositely wound coil 43 attached to the beam 14 with the coil 42 is connected to the amplifier 34 as shown. The coil 43 acts to initially and temporarily cause the amplifier 34 to deliver a higher current than would be required for producing the restoring force. The net effect is that a state of equilibrium is more quickly reached.

Abstract: 1534921 Valves POCLAIN 25 June 1976 [15 July 1975] 26627/76 Heading F2V A flow regulator 9 is disposed in the delivery line 6 of a fluid motor 4 and is urged to an open position by the fluid pressure in the supply line 5 of the motor 4 and is urged to the closed position by a spring 20 and by the fluid pressure in exhaust line 7 between the regulator 9 and restriction 10 located downstream of the regulator. The pressure in the line 5 acts on a piston 17 to urge a slide valve 22 to the left, Fig. 2, against the force of the spring 20. When the valve 22 has been moved so that apertures 29 are in communication with groove 30, Fig. 5 (not shown), fluid flows from the line 6 through the apertures 29, the restriction 10 and apertures 32 into line 8 leading to tank or to a further fluid device; the resulting fluid pressure across wall 25, in which the restriction 10 is formed, serves to brake the opening movement of the regulator. When the valve 22 reaches the fully open position, Fig. 6 (not shown) fluid from the line 6 flows through apertures 31 downstream of the restrictions 10 so that the pressures across the wall 25 are equalized.
