Abstract: 907,857. Air-break switches; actuation of switches. SWITCHGEAR & EQUIPMENT Ltd., and OXLEY, D. A. J. Nov. 18, 1960 [Aug. 19, 1959], No. 28300/59. Class 38 (5). [Also in Group XXIV] Switchgear operating mechanism, e.g. that of an air-break isolator, comprises a drive-shaft 25 extending transversely to, and with its axis 26 intersecting the axis 16 of rotation of, a driven member 34 arranged to open and close the switch contacts, the drive-shaft being connected to drive the driven member through coupling means including a crank-pin 29 connected to the drive shaft 25 at a point displaced from the shaft axis and inclined at an acute angle to the shaft axis and extending inwards towards the point of intersection of the shaft axis and the driven member axis, the coupling means being such as to permit relative rotation between two parts of the coupling means about the axis of the crank-pin and about an axis transverse to the axes of the crank-pin and the driven member.

Title: Heat and sound insulation arrangement
IPC: F26B25/22
Filed: 1974-06-26
Abstract: 1480834 Thermal and sound insulation P CLEMENT and J-L JUILLARD 26 June 1974 [27 June 1973 20 June 1974] 28405/74 Heading F2X [Also in Divisions B5 and F4] A thermal and sound insulation arrangement comprises at least one insulating layer disposed between two outer layers forming part of a wall or floor of a building with a series of projections on one surface of the insulating layer being arranged in a uniform matrix of mutually perpendicular rows to define channels between the rows through which a fluid may flow, the ratio of the surface area of the insulating layer covered by the projections to the whole surface area being no greater than 0À25 : 1. As shown in Fig. 1, a floor may comprise a base layer 1, a cover layer 2, and an insulation material sandwiched between the layers 1, 2. This material forming the insulation comprises two outer layers 4, 5 separated by a series of projections 3 to allow the circulation of a fluid. The projections 3 are of the same material as the lower layer 4 and preferably integral therewith, the upper layer 5 being carried on top. Alternatively (Fig. 2, not shown), the layers 4, 5 are contiguous with the projections 3 supporting the lower layer 4. The layers 4, 5 are chosen so that one has good sound insulation properties and the other good thermal insulation properties. Air may circulate in the walls and floors of a building through the channels defined by the rows of projections and provide heating or cooling as required (Fig. 3, not shown). When the outer layers of the walls are warmed by the sun, the heat is removed by the air circulating in the channels in the walls which then flows through a heat exchanger at the top of the building. If one wall faces south and an opposite wall faces north, the former will tend to be warmer than the latter. These two walls therefore provide a heat source and a heat sink, respectively, enabling air from the hotter wall to be cooled by air from the cooler wall. In one method of manufacture, the projections are formed by the longitudinal and transverse cutting of a thick thermal insulating plate and the sound insulation is then glued on top. Alternatively, two thermally insulating plates are longitudinally and transversely cut to form half-height projections on each. The two plates are superimposed with the projections joining end to end. A sound insulating layer is then glued on to at least one of the faces. The layers can also be manufactured by moulding or polymerization in situ. The projections can be solid or hollow.

Title: A process for the production of olefine alcohols and their derivatives
IPC: C07C29/60
Filed: 1933-10-17
Abstract: Olefine alcohols and their derivatives are made by heating polyvalent aliphatic secondary or tertiary alcohols or their derivatives with a hydroxide of thorium, titanium, or zirconium, preferably below the boiling-point of the polyvalent alcohol.  In an example, 1 : 12 - octodecanediol is heated with stirring and while passing in nitrogen, with a catalyst made by precipitating thorium nitrate with sodium carbonate in presence of kieselguhr and washing and drying the precipitate, which then contains 20 per cent of thorium.  The process is effected at 220--250 DEG  C., which is finally raised to 300--305 DEG  C.ALSO:A catalyst for the conversion of polyhydric secondary and tertiary alcohols into olefine alcohols is made by precipitating thorium nitrate with sodium carbonate in presence of kieselguhr and washing and drying the precipitate which then contains 20 per cent of thorium.

Title: Improvements in frequency changers for heterodyne receivers and modulators
IPC: H03D7/10
Filed: 1936-10-22
Abstract: 489,486. Valve circuits for wireless reception and modulating; thermionic valves. KRAMOLIN, L. L. DE. Oct. 22, 1936, No. 28764. Convention date, Oct. 24, 1935. Addition to 409,756. [Classes 39 (i) and 40 (v)] In a frequency changer for receiving or a modulator the output of which comprises a frequency modulated signal and comprising two electron paths in series, one controlled by the signal and the other by a local oscillator, both paths are adjusted to operate within the straight parts of their characteristics instead of, as described in the parent Specification, only the path to which the signals are applied being so adjusted. Fig. 2 shows an arrangement in which an auxiliary grid of one system is connected to the cathode of the other system in which the signal path and preferably the local oscillator path are adjusted to operate within the straight part of their characteristics. The output may be taken from either anode 5 or anode 6 or from both in push-pull. The local oscillations may be applied to the two paths in push-pull and may be generated by backcoupling one or both of the discharge paths to which the local oscillations are applied Figs. 3 and 4 (not shown). Alternatively the incoming signals may be applied to paths in push-pull and in series with a path to which the local oscillations are applied. A pair of discharge paths may be arranged in push-pull and to generate the local oscillation the cathodes being connected together and to the anode of the discharge path to which the signal is applied. The capacitive leakage resistance to earth of the cathode of the discharge path remote from earth is made greater than the internal resistance of the preceding discharge path or system and the cathode is of small diameter as described in Specifications 415,079 and 427,384. The second cathode may be a " virtual cathode " comprising a space charge region formed by electrons of slow speed between a positive grid and a succeeding negative grid. Fig. 6 shows an arrangement of this kind in which the valve comprises a grid 1 and grid like anode 6 and two oscillator grids 4, 11 arranged side by side and correspondingly arranged anodes 5, 10. The electron paths 4, 5 and 10, 11 may be separated by a mica or metal foil partition which may also be utilized as the mechanical support of the electrodes. The bias of grids 4, 6, 11 is adjustable by potentiometer 13 to vary gains. The invention is particularly applicable to superheterodyne receivers having an aperiodic or semi-aperiodic input in which tuning is effected by varying the local oscillator frequency. Specification 437,726 also is referred to. Reference has been directed by the Comptroller to Specification 462,428.
