Abstract: 1,206,421. Removing combustible matter from solid waste. L. STEWART. 15 Sept., 1967 [15 June, 1966], No. 26784/66. Headings F4B and F4G. Combustible volatiles are removed from solid material e.g. waste insulated cable or oily swarf by passing jets of air outside a charge of the material to entrain the volatiles which burn within the working chamber but outside the charge. The air is supplied to a charge on a grate 11 by air inlet pipes 12 having nozzles 13 and rotatable about their longitudinal axes so that the jets of air from nozzles 13 do not enter the charge. Secondary air from an inlet pipe 14 mounted at right angles to the pipes 12 and fixed with its nozzles 15 directed vertically, entrains the burning gases from the working chamber to complete combustion within an involute passage 17 leading to a flue 16, which is common to a number of furnaces arranged sideby-side. The charge may be passed through a furnace on a moving hearth, and may be electrically heated. The secondary air issuing from the pipe 14 may be preheated and the temperatures below the secondary air supply pipe 14 and in the involute passage 17 may be compared to give an indication of the progress of the removal, and to control the direction of the primary air jets. The entry to the involute passage leading to the flue may be spaced from the furnace roof to avoid overheating of the flue.

Abstract: 1376961 Function generators HONEYWELL Ltd 11 June 1973 [9 June 1972] 26941/72 Heading G4G A function generator comprises a plurality of rectifying circuits DE1 to DE5 connected in parallel between an input 20 and a summing amplifier A11 and each biased to conduct with a particular resistance at a particular input voltage so that the characteristics of the rectifying circuits sum to form a combined characteristic of segmented form, and the function generator also includes a non-rectifying biased connection through resistor R17 between input 20 and the summing amplifier All, which connection provides a straight characteristic coinciding with a substantially central region of the combined characteristic so that the rectifying circuits form segments extending to one or the other side of the central region according to their polarity. Rectifying circuits DE1 to DE3 are reversed with respect to DE4 and DE5 since they are used to provide segments on opposite sides of the central region and consequently an inverting amplifier A10 is provided. The rectifying circuits are not necessarily actual diodes but can consist of an operational amplifier circuit connected so as to function as an ideal diode Fig. 1A (not shown). In an alternative embodiment, Figs. 4 and 5 (not shown), the rectifying circuits take the form of diodes (D12 to D17), which can provide feedback paths for a single operational amplifier (A30) in dependence on the input voltage.

Title: Improvements in or relating to weighing balances
Inventor: BEAL ALBERT WALTER
IPC: G01G23/32
Filed: 1953-10-01
Abstract: 759,619. Weighing-apparatus. WEBB, Ltd., W. A. Sept. 30, 1954 [Oct. 1, 1953], No. 26985/54. Class 143 A pivoted beam balance has its deflection indicated by the optional projection of a graticule, the parts of the optical system, including the graticule but excluding the viewing screen, being placed beneath the base plate. The graticule 21 is mounted on a rod 16 depending on the balance beam 14, and its image is projected by lens 36, and mirrors 38, 48, on to a ground glass screen 52. The mirror 38 is adjustable in angle by screw 44 to contre the image on the screen. The optical system, excluding the graticule, is on a sliding plate 26 movable by a screw (not shown), to give image focusing. A wire 43, mounted eccentrically on a screwed rod 54, below the screen, provides a reference shadow, adjustable by a screw 56. Movement of the shadow relative to the graticule divisions is determined by the reading on a scale 60 of a pointer, attached to screw 56. This provides vernier readings. In a modification, the wire 53 is replaced by a vane, so that rotation of the screw causes one shadow edge to remain still and the other to move to coincide with a graticule division. In a further modification, the vane is replaced by two pins, which correspond to the vane edges on operation of screw 56. The assembly of 53, 56 and 60 can be moved laterally by a spring- loaded screw to give an itial zero setting of the reference shadow. Finally, the lamp 33 for the optical system is lit only when the beam is raised by its manually operated lever.

Abstract: 503,499. Silica Ware. HAUSER, M. Oct. 5, 1937, No. 26992. Convention date, Oct. 6, 1936. [Class 56] [Also in Group V] Non-porous articles such as chemical ware and insulators consisting mainly of amorphous silica are made by shaping and firing by the usual ceramic methods a mix comprising amorphous silica, a flux promoting vitrification and a colloidal mineral binder such as bentonite conferring plasticity to the mix. The silica may be fused sand or quartz, opal, kieselguhr or the like, or it may be obtained by chemical decomposition of silicates. The grain size of the silica is preferably graduated according to the Fuller curve to obtain a dense product, but if a porous silica is utilized as the raw material, it must first be freely ground. The flux may be felspar, phosphates or artificial frits or glasses. Inert materials such as clay or kaolin may also be incorporated in the mix. The firing is conducted rapidly to maintain the silica amorphous. The Specification as open to inspection under Sect. 91 refers also to the use of colloidal binders of silica gel and alumina gel. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to detector circuits for angle-modulation receivers
IPC: H03D3/06
Filed: 1946-09-10
Abstract: 624,011. Frequency ; phase modulation. RADIO CORPORATION OF AMERICA. Sept. 10, 1946, No. 27134. Convention date, Sept. 10, 1945. [Class 40 (v)] A detector for providing amplitude modulated output depending on angle modulated waves, comprises a single rectifier fed by network providing parallel resonance at a frequency on one side of a centre frequency and series resonance on the other side. As shown in Fig. 1, angle modulated waves are applied through coupling condenser 5 to a diode 3, the anode and cathode of which are connected to a coil 7 and load resistance 8 shunted by an R.F. byepass condenser 9. The output is taken from the anode end of resistor 8. A linear discrimination characteristic is provided by shunt resonating the the coil 7 and the anode cathode capacitance 10 of the diode to a frequency slightly higher than the mean frequency of the wave to be modulated. A series resonant point falling below the mean frequencies is also obtained by utilizing either condenser 5 or 9 or both in series with the coil 7 and capacitance 10. The frequency response curve between these two points is linear and sufficiently steep to provide maximum output over the entire frequency deviations of F.M. energy applied. Preferably a locked-in oscillator 1, as described in Specification 562,993 is utilized prior to the detector stage. In a modification, instead of relying on the internal capacity of the diode a physical condenser may be connected across the coil 7 (Fig. 4, not shown). In a further embodiment 6, Fig. 5, a resistor 51 is connected between the coupling condenser 5 and the diode anode 2 and variable resistors 7<1> and 8<1> are connected in parallel with the coil 7 and condenser 9 respectively to vary the " Q " of the shunt and series resonant circuits. Resistor 14 forms the diode load and the combination of resistors and condensers 15, 16, 17, 18 from a do-emphasis circuit from which the output is taken. In a further modification (Fig. 10, not shown), the resistor 8 and condenser 9 in parallel are replaced by a condenser in series. In this case the shunt circuit resonators below and the series circuit above the mean frequency. Specification 612,585 also is referred to.
