Abstract: 383,258. Wire resistances electric radiators. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. - (Assignees of Randolph, C. P. ; 727, Columbian Avenue, Oak Park, Illinois, U.S.A.) Feb. 3, 1931, No. 3455. Convention date, Feb. 3, 1930. Void [Published under Sect. 91 of the Acts]. [Class 37.] An electric radiant heater comprises a heating element 10 co-operating with a reflector 11, the element 10 having a cylindrical body 16 and a flat plate-like extension 17, both the body and extension carrying the resistance wire 14 which is arranged in grooves on the inner face of the flange 17 in order to distribute the heat uniformly over a pre-selected area. The resistance wire 14 is arranged in grooves 27, 25 in the hollow cylindrical and flat parts 16, 17 and is held in position in the grooves 25 by members 26 formed integrally with the flange 17 and projecting over the grooves at the bends. The unit is formed of three parts, the plate 17, hollow cylinder 16 and terminal base member 18 secured together by a central screwed pin 19 and centred on each other by projections 24, 23 on the members 18, 16 and recesses 24a, 23a in the members 16, 17 respectively. Connections to the resistance wire are made by leads 28, 33 passing through the hollow cylinder 16 and bores 31, 34 in the engaging face of the member 18 which is formed with an open compartment 32 where the leads 31, 32 are secured to strips 36, 37 connected through bores 41, 42 in the end of the member 18, to a screwed metal cap 40 and the head of the bolt 19 at the outer end of the member 18. A socket in an extension 43 of the reflector 11 is arranged to receive the end of the member 18 and has a central and a peripheral current contact. Substantially all the heat is reflected heat and the heat distribution may be varied by altering the relative concentration of resistance wire on the cylindrical member 16 and the flange member 17.

IPC: C11B11/00
Filed: 1944-02-25
Abstract: 575,642. Extracting vegetable waxes. AFRICAN SISAL & PRODUCE CO., Ltd., WALSH, C. L., and HOAR, T. P. Feb. 25, 1944, No. 3522. [Class 91] Wax-like products are extracted from sisal and like plant flesh, after removal of the main bulk of fibre, by first drying the material and then subjecting it to extraction under refluxing conditions with an organic solvent at or just below its boiling point, the solvent being finally distilled off from the separated solution. The solvents specified comprise petroleum benzine, trichlorethylene, benzene, petroleum ether, and acetone and mixtures thereof, the solvent used governing to some extent the colour, hardness &c. of the wax-like products obtained. Examples are given of the extraction using petroleum benzine alone; petroleum ether alone, followed by re-extraction of the remaining plant flesh material with a mixture of petroleum ether and acetone; or re-extraction of either of these last residues with trichlorethylene; and using trichlorethylene alone on the original material. The waxlike products may be modified, probably polymerised, by heating above 100‹C.

Title: Improvements in or relating to electric frequency modulating circuits
Inventor: MCLEOD THOMAS SYMINGTON
IPC: H03C3/06
Filed: 1951-02-15
Abstract: 677,970. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. Feb. 15, 1951, No. 3681/51. Class 40 (v). With the object of raising the frequency deviation of a frequencymodulated wave without making a proportional increase in the mean carrier frequency, the primary FM wave is mixed with waves from two further sources, the upper side-band is selected from one of the mixer outputs, and the lower side-band from the other, the two selected side-bands are mixed with each other, and the lower side-band selected to provide the output. As shown, a FM wave is produced by applying the signal through an amplifier 1 to give a frequency deviation f in opposite senses to waves of frequencies F1, F2 generated by sources 2, 3. The outputs are mixed at 4, and the difference frequency, F1 - F2 + 2f, selected by filter 5, constitutes the primary FM wave. According to the invention, this wave is mixed at 6 and 7 with waves of frequencies F3, F4 respectively generated by sources 8, 9. The upper side-band is selected by a filter 10 from the output of mixer 6, and the lower side-band from the output of mixer 7 by a filter 11. The selected side-bands are mixed at 12, and the lower sideband selected by a filter 13 provides an output FM wave whose deviation is double that of the primary FM wave and whose mean frequency is changed to a less degree. Further, similar frequency-changing stages may be provided, the mixing waves being supplied by the sources 8, 9 or by other sources of different frequency.

Abstract: 668,676. Valve circuits for radio reception. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 14, 1950, No. 3760/50. Class 40 (v). In a video detector circuit using a diode, the transfer of R.F. energy to subsequent stages is prevented by providing an earthed tap on the inductance 2 feeding the diode, one end of the coil 2 being connected to the anode of the diode and the other to the cathode via a capacitor 8; the turns ratio of the two parts into which the inductance is divided by the tap is made equal to the ratio of the internal capacity 14 of the diode to that of the capacitor 8. The capacity resonating the inductance preferably comprises the capacities 8, 14 in series. The load resistance 7 is shunted across the capacitor 8 or may alternatively, Fig. 3 (not shown), be returned direct to earth.

Abstract: 1,085,761. Current measurement. L.H. WOLGAST. Feb.1, 1965 [Feb. 4, 1964], No.4341/65. Heading G1U. In a method of measuring the current in a selected anode of a multiple anode electrolytic reduction cell, a Hall effect generator is disposed much closer to a conductor carrying current to the selected anode than to the conductors for the other anodes and arranged such that the magnetic field produced by the current in the conductor is perpendicular to the plane of the wafer of the Hall effect generator. A current is passed through the wafer in one direction in the plane and the voltage appearing between points in the wafer on a line transverse with this direction is measured. An apparatus suitable for carrying out the method consists of a casing 11 accommodating batteries and having mounted upon it a meter 16 and a probe 19. The probe incorporates at its end a flat Hall effect generator consisting of a wafer of indium, antimonide or arsenide which is adapted so that it may be located in proper position against the anode so that the field due to the current therethrough is perpendicular to the plane of the wafer. When the current supply to the wafer from the batteries is switched on, the voltage output from the wafer is detected and indicated on the meter.
