Title: Improvements in and relating to electrically heated flatirons
IPC: D06F75/34
Filed: 1948-10-01
Abstract: 666,326. Hand irons. BRITISH THOMSONHOUSTON CO. Ltd., Oct. 1, 1948 [Oct. 2, 1947], No. 25633/48. Class 138 (ii). In an electric iron having a pivoted handle 24, a. latch member 29 is urged by a spring 32 toward engagement with the handle, and a. locking member 33 holds the handle and latch in latched position. The handle 24 is bifurcated at one end which straddles and is pivoted to a U-shaped bracket 19 by means of pins 25 in bearing holes 26 in the bracket. A projection 27 in the crotch of the bifurcation is engaged by a complementary latching portion 28 on the latch 29 which is hinged or pivoted to the bracket 19. A lip 31 at the top of the latch 29 engages with the projection 27 to prevent the handle from rising higher than its operating position. When the handle is raised it will become latched in its operating position by the action of the Z-shaped spring 32 and latch 29. The U-shaped locking lever 33, pivoted to the bracket 19 on the pins 25, prevents the return of the handle to folded position. The locking action is obtained by forwardly extending arms 34 provided with inturned cam surfaces 35 which bear against pressure areas 36 on the latch 29. In its open position the locking lever functions as a plug socket for receiving the usual supply plug for engagement with terminals 18, and it also acts as a heel stand for the iron in co-operation with the back edge of the iron. Dimples 38 on the sides of the arms 34 frictionally engage the inside of the legs of the handle and tend to hold the locking lever in its opened position. In its forward position the lever serves as a guard for the terminals. The bracket 19 is also used to secure a bottom cover-plate 13 in place. Lips 42 on the front edge of plate 13 engage in slots 41 in upstanding ears 39 welded or otherwise fastened to the back edge of the sole plate 10. The rear edge of the plate 13 is held in place by a spring clip 43 riveted to the plate and having near its free end an angular portion 44 which snaps into notches 23 on ears 22 of bracket 19. Interfitting flanges 20, 30 on the cover-plates 11, 13, respectively, prevent relative shifting of the parts.

Filed: 1955-09-08
Abstract: 796,656. Photo-electric cells. VEB. C. ZEISS JENA. Sept. 8, 1955, No. 25780/55. Class 37. [Also in Group XL (b)] A photo-electric photometer comprises a lead sulphide or other photo-voltaic cell on which light rays S1, S2 of a standard 1 and unknown intensity respectively are simultaneously incident so as to make equal but opposed angles α with the normal to the cell surface. The cell is such that the magnitude and size of the voltage produced when a light ray is incident thereon depends upon the angle of incidence. Thus, by ensuring that the angles of incidence of the rays S1, S2 are equal and opposite, the resultant voltage, as measured at 4, depends upon the difference in the intensities of the rays.

Title: Improvements in or relating to filter circuit arrangements

Abstract: 1,222,604. Transit time filters; multiplex transmission. SIEMENS A.G. 30 May, 1968 [31 May, 1967], No. 25907/68. Headings H3U and H4K. A transversal or digital filter of the type utilizing one or more delay devices the outputs of which are combined with their input signals in such proportions as to obtain a required filter characteristic is used to filter the individual channels on a time division multiplex highway by arranging that the delay in the delay devices in the filter is an integral multiple of the time between successive appearances of any one channel on the highway such that the combining circuit is at any time only dealing with signals from one channel. Fig. 11 shows an arrangement equivalent to a conventional parallel resonant circuit, with the factors X and Y, used to determine the resistors 1/X and 1/Y, related to the constants of the equivalent resonant circuit by eqtns. given in the Specification. The delay devices LS1 and LS2 have delays between their inputs and outputs which are an integral multiple of the multiplex frame period, and have negligibly low input and output impedances, allowing simple determination of the resistive combining circuit values and simple interconnection of similar circuits. Arrangements equivalent to an RC integrating circuit, and to a low pass filter are described with respect to Figs. 7 and 14 (not shown). Also described is an arrangement for demodulating a carrier tdm system utilizing a band pass filter BP Fig. 17 a detector G, and a low pass filter TP where the band pass and low pass filters are of the type according to the invention. An amplitude discriminating threshold circuit AHP may be included at the output of the filter circuit to discriminate against noise. The filter may be connected to the tdm highway by a switching device enabling only selected pulses from a channel, e.g. every alternate pulse, or only samples of each channel pulse, to be fed to the filter. Two or more tdm highways may be connected to one filter by applying the channels from each highway in tdm. The characteristics of the combining network may be changed cyclically during the tdm frame to provide different filtering characteristics for different channels. Reactive elements may be included in the combining circuit provided that transient phenomena associated with the reactances are terminated, e.g. by a further switch, before another signal pulse from another channel is fed to the filter.

Title: Recovery of the tetrachlorides of tin, titanium and silicon
IPC: C01G1/06
Filed: 1958-08-12
Abstract: Tin, titanium, and silicon tetrachloride are recovered from sludges containing solid impurities generally in the form of solid chlorides, for example, ferric chloride, by dispersing the sludge in a stream of a hot gas inert thereto to rapidly vaporise the liquid chloride, whilst entraining the solid.  The dry solids are separated from the resulting mixture, and the liquid metal chloride thereafter recovered.  The final temperature of the gas may be 5 DEG C. to 100 DEG C. above the dew-point of the liquid chloride. The hot gas may be air, nitrogen, hot chlorination gas resulting from the production of the liquid metal chloride, or the superheated vapour of the liquid metal chloride.  After the major part of the liquid chloride has been recovered from the gas, the gas may be reheated and recycled.  In a closed system 1-20% of the gas may be replaced for each circuit.  The sludge may be dispersed by nozzles or centrifugal discs, such as are employed in spray-drying apparatus, or it may be sprayed in the form of a dispersion into the throat of a Venturi tube through which the hot gas moves at high velocity.  The outlet of the Venturi may be heat insulated to prevent ferric chloride deposition.  When the greater part of the solids have been removed in the dry state, the remainder may be washed out by means of hot liquid metal chloride to form a sludge which is recycled.  The dry solids are in the form of a fine powder which is easily removed, and may be agglomerated for ease in handling.  To enable the sludge to be satisfactorily dispersed the solids content should be less than 30% and preferably less than 20%.
