Abstract: 874,790. Loud-speaking telephone sets. MODERN TELEPHONES (GREAT BRITAIN) Ltd., IVENS, E., and SIMPSON, A. I. F. Dec. 7, 1959 [Dec. 10, 1958], No. 39882/58. Class 40 (4). In a loud-speaking telephone arrangement, a loud-speaker is placed inside and at one end of the front face of a cabinet 10 (Fig. 1) and a microphone 26 (Fig. 4) is placed outside the other end face of the cabinet at a position where the highfrequency sounds are masked and where there is a minimum intensity for low-frequency sounds due to the cancelling effect of the sounds travelling along different paths, this arrangement minimizing singing. The loud-speaker may be placed behind a dial assembly 11 (Fig. 1) and inside the cabinet 10, which has an opening at the back, equivalent in area to the openings at the front, so that air column resonance is reduced and the said cancelling effect enhanced. The cabinet may also have provision for a key 12 and indicator 13 board. The microphone housing 22 (Fig. 4) has a grille 25 as its front face behind which is a crystal microphone 26, placed inside an aperture in a sponge rubber sheet 27, sandwiched between two further sheets 28, 29. The microphone leads to the cabinet are run through suitable channels in the rubber sheets above the microphone, thus further minimizing acoustic coupling. A telephone handset (Fig. 2, not shown) may rest on a cradle attached to member 19 (Fig. 4) which can operate push rod 23, connected by a link 24 to a switch mechanism in the cabinet. The cabinet may also house an amplifier.

Abstract: 1505913 Infrared gas analyzers STANDARD TELEPHONES & CABLES Ltd 28 Sept 1976 [2 Oct 1975] 40309/75 Heading G1A An infrared gas analyzer has a black body source which is heated sequentially to various predetermined temperatures, and a black body detector which receives the source radiation after passage through the gas mixture to be analyzed. The wavelength of maximum source emission changes each time its temperature is changed, and hence a coarse wavelength scan is performed. The detector output is passed to a microprocessor which compares it with a theoretical gas having no emission or absorption bands at the wavelengths used, so as to compute the actual absorption by the gas and hence its composition. The invention is suitable for analysis of flue gases, and absorption bands of typical flue gases are given, Fig. 3 (not shown).

Abstract: 1,244,780. Ammonium thiocyanate. DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT. 14 Aug., 1969 [14 Aug., 1968], No. 40627/69. Heading C1A. Ammonium thiocyanate is prepared by reaction of anhydrous ammonia, hydrogen cyanide, and sulphur in a reaction medium of ammonium thiocyanate, and ammonium polysulphide, in ammonia solution. The sulphur may be added before reaction with hydrogen cyanide, thus permitting a continuous process wherein reaction mixture is bled off so that the rate of removal of ammonium thiocyanate is equal to the rate of its formation, whilst the remainder of the reaction mixture is recycled for addition of ammonia and sulphur. At normal pressures the reaction is carried out at 0-70‹ C., but increased pressure and temperature may be employed. Ammonia and hydrogen sulphide are removed from the product by evaporation and any sulphur remaining is removed by recrystallization of the thiocyanate.

Title: Nozzle construction for air curtains in refrigerated cabinets
IPC: A47F3/04
Filed: 1964-10-20
Abstract: 1,082,235. Refrigerators. DUAL JET REFRIGERATION CO. Oct. 20, 1964 [Dec. 9, 1963], No. 42731/64. Heading F4H. In a front-access refrigerated display cabinet of the type in which an air curtain consisting of at least two adjacent air panels is projected across the access opening, the nozzle for forming the outer panel is so constructed, or has means so associated therewith, that the velocity of the air at the edge of the panel adjacent the inner panel is greater than that at the other edge of the panel. As shown in Fig. 2 the nozzle for forming the outer air panel comprises separated sections 56, 54, the latter being of substantially triangular form in vertical section and being arranged to direct more air to the inner than to the outer passages of section 56. The upstream edge of the nozzle 46 for forming the inner air panel is sloped so that the outer passages of the nozzle receive more air than the inner passages. Thus the velocity of the air in the air curtain is greatest at the interface between the panels. In the embodiment of Fig. 4 the nozzle 66 for the outer panel is so constructed that the lengths of the passages therethrough progressively increase from the inner to the outer edges of the nozzle to provide the desired velocity gradient. In the embodiment of Fig. 6 (not shown), an apertured screen is arranged upstream of the outer nozzle, the apertures being of progressively increasing size from the outer to the inner edge of the screen. The latter may be replaced by slots the spacing between which increases inwardly (Fig. 7, not shown). In the embodiment of Fig. 3 (not shown) the nozzle section 54 of Fig. 2 is modified in that its passages are arranged parallel to those of section 56 and its upstream edge is curved, the radius of curvature decreasing inwardly so 'that the inner passages receive more air than the outer passages. In a further modification (Fig. 5, not shown) a set of parallel louvres is arranged upstream of the outer nozzle so as to direct more air to the inner edge of the latter.

Title: Method and apparatus for straightening lengths of material particularly rods and tubes
IPC: B21D3/02
Filed: 1974-10-02
Abstract: 1478151 Straightening; skew rolling TH KIESERLING & ALBRECHT 2 Oct 1974 [3 Oct 1973] 42804/74 Headings B3E and B3M In a roller straightening machine, the presence of a length of material is sensed, and straightening force is gradually applied to the leading end of the length, and gradually removed from the trailing end. In Fig. 1, the sensor 10 triggers a time function generating circuit 7 operating a valve 6 which controls the fluid pressure in a straightening-forceapplying cylinder 3. Time-delay circuits 11 and 12 are preset, and potentiometers 8, 9 control the amplitude of the regenerator output and the time over which the force is applied. By this means, the formation of a portion of increased diameter at the end of, e.g. a rod can be reduced. Figs. 6 and 7 show a skewrolling stand having an upper hyperbolic roll 15 driven by shaft 44 and a lower slightly convex roll 16 driven by shaft 45. The upper roll is rotatable about axis 62, being mounted on a carrier 53 arm 54 on which is connected to a nut and spindle gear 55, 56, the spindle being mounted on universal joint 59 and rotatable by D.C. motor 61 through V-belt and pulley mechanism. The lower roll 16 is adjustable vertically by the hydraulic cylinder 3. Similar circuitry to that of Fig 1 is used to control the angular position of roll 15. When the invention is applied to a multi-roll straightener through which the work follows a sinuous path, the downstream roll of three consecutive rolls is gradually moved from an inoperative to a fully operative position as the leading edge advances, thus gradually applying bending force to the leading edge.
