Title: Attachment of fittings to a planar support
IPC: E06B3/02
Filed: 1974-04-25
Abstract: 1452812 Hinges SAINT-GOBAIN INDUSTRIES 25 April 1974 [25 April 1973 3 May 1973] 18111/74 Heading E2F [Also in Division F2]  An attachment member, e.g. a stirrup-shaped strap 4 of a hinge assembly 4, 19, 27, is secured to a panel 1, e.g. a glass door, by securing on opposite faces of the panel a number of studs, either using a separate adhesive or, preferably, by casting the studs directly on the panel from an adhesive material, e.g. epoxy resin, using a suitable mould, the strap 4 being then positioned so as to embrace the studded area and being attached to the studs by intermediate perforated plates 12, 13 which interlock with the studs and with the strap, after which a securing device is tightened to hold the parts in assembled condition. In the embodiment of Figs. 1 and 2, the strap 4 is first positioned with the studs arranged within an area enclosed by an aperture 11 in each of the limbs 5 of the strap, perforated plates 12, 13 then being fitted into the apertures 11 so as to interlock the strap with the studs 3, after which plates 15 are fitted across the apertures 11 by screws 17 and bear against the plates 3 via rings 16 to secure the assembly. Recesses 6 in the limbs 5 allow the strap to be slid into position over the studs. The hinge structure shown consists of the strap 4, a knuckle 19, half-hinge 27 and hinge pin 28. The knuckle is joined to the strap by interengaging a semi-circular bearing surface 9, formed on the strip 7 joining the limbs 5, with a semi-circular recess 9' in the knuckle and securing the assembly by a screw 25 and threaded sleeve 26, checks 22 on the knuckle providing the recess with undercut portions so that the strap 4 is retained to the knuckle with a keying action whilst allowing limited relative rotation about an axis 20. Since limited rotation of the strap about a transverse axis passing through the centres of the apertures 11 is also possible the bores 29, 30 in the knuckle 19 and half-hinge 27, respectively, for receiving the hinge pin 28 are rendered self-aligning. In a modification, Fig. 5, this self-aligning is provided for by allowing some clearance between the limbs 36 of a modified strap and the panel 31 on all sides, perforated plates 32 engaging the studs 33 being resiliently held in interlocking relationship with the strap by curved spring sheets 44.

Abstract: 473,498. Thermionic valves. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. June 30, 1936, Nos. 18118 and 24127. [Class 39 (i)] A short-wave or ultra-short wave generator comprises a unitary structure having at least two electrically independent cathodes, at least two anodes and a control grid common to both anode-cathode streams, or two control grids and a common anode, and an inductance connected between the two grids or the two anodes. The generator is of the type described in Specification 450,967. The capacity between the cathodes should be low and the cathodes may be indirectly-heated by electrically independent heaters. Two, four or more structures may be combined within one envelope, e.g. four structures may be so arranged and each pair of grids may be connected together by a member as far as possible devoid of inductance. A valve may comprise two hairpin or W-shaped filaments mounted upon axial re-entrant stems of a cylindrical envelope. A continuous control grid or two control grids of wound form and connected together surround the cathodes. Two separate cylindrical or box anodes surround the grids. In another form two parallel cathodes are enclosed, one in each loop, of a grid in the form of a figure of eight. The common grids or anodes may consist of separate grids or anodes connected together so as to be incapable of relative potential variation. The anodes consist of wire, sheet mesh or of wound grids.

Filed: 1949-07-09
Abstract: 676,306. Impedance networks. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 10, 1950 [July 9, 1949], No. 18196/49. Class 40 (viii). A signal transmission arrangement comprises a resistive load impedance and a source of energy whose resistive impedance is matched to the load at two frequencies by a length of transmission line connecting the load and source, an impedance being connected in shunt with the source to balance out the reactance produced by this arrangement at the two frequencies of operation. The Specification contains a mathematical treatment for obtaining the required values of the parts of this circuit for particular cases. The impedance in shunt with the source may be a short-circuited section of line. In order to avoid too high a ratio of transformation in one step, as shown, a number of short-circuited lines Z20, Z21 and Z22 may be arranged at intervals along the line connecting terminals 2 and 3, to which the source is connected, with the resistive load 1. Each short-circuited line with its accompanying section of the transmission line acts to transform a resistive impedance and balance out reactance as in the simple case first described.

In Fig. 2 (not shown), the rear curtain is initially formed by air drawn through a valve controlled port, thisair being replaced by the recovered fluid when the vehicle is operating; in Figs. 3 and 5 (not shown) the recovered air forms a curtain rearwardly of a primary curtain and part of this primary curtain is also recovered in Fig. 6. Cross flow blowers are used to create the front curtain and to energize the recovered fluid in Fig. 4 (not shown). In Fig. 7, closed recirculation curtains 50, 55 are formed at the front and rear and the recovered air from the front curtain issues from port 69 to form a second rear curtain. The air for curtain 55 is initially taken in through opening 70 and pipe 59. In Figs. 8, 9 (not shown), the air for the rear primary curtain is taken in at the sides of the vehicle and passes along a transverse duct having a slot, part of this curtain is recovered to form the secondary rear curtain. The cushion may be subdivided and may be partly contained by side walls.

The blades B is mounted on a carrier 16 adapted to fit into a slotted tube 15 rotatably mounted in the ends 13, 13a of the frame, and the tube is oscillated about its axis to bring the blade into contact with the rollers by means of a. spirally formed extension 20 working in a slot in the part 9. Passing through the spindles 10 are two spirally formed rods 23 connected by a handle 22, the spindles being formed with slots at the ends 11 so that reciprocation of the rods will cause rotation of the rollers. The blade-holder is held against accidental displacement by means of a disk 24 fixed to one of the spindles 10 and engaging a notch 26 in the carrier 16; the disk is disposed slightly diagonally in order to impart a slight reciprocation to the carrier and the blade. In operation, the bars 23 are moved by the handle 22, this movement first moving the rollers and spindles axially, and then, towards the end of the stroke, causing rotation of the rollers; the axial movement of the spindles also moves the frame 12 and thus causes oscillation of the blade-holder. In a modification, the apparatus has one grinding-roller only.
