[Also in Group XXX] A slewing base-plate 4, on which an appliance to be slewed may be mounted, is supported by a kingpin 5 secured to the inner gear 6 of a ring gear and connected to a rotating part 1 of a ballbearing slewing gear. Slewing is effected by an hydraulic ram which is pivoted at 23 to arms 24, 24<SP>1</SP> attached to discs 11, 12 which support three intermediate gears 8. The intermediate gears mesh with an outer ring gear 14, supported on a frame 3 by arms 16 and resilient bushes 17, and also with the inner gear 6. Rotation of the discs 11, 12 by the ram causes the inner gear and base-plate 4 to rotate through a greater angle. Movement of the discs through 72 degrees can result in a 360 degrees rotation of the base-plate. This ratio may be varied by altering the gearing. Gaskets 20, 20<SP>1</SP> allow the mechanism to run in oil.

Title: Vacuum cleaner having a motor temperature sensing device
IPC: H01H37/66
Filed: 1975-04-02
Abstract: 1442962 Vacuum cleaners ELECTROLUX LTD 2 April 1975 [19 April 1974] 13528/75 Heading A4F [ Also in Divisions B1 G1 and H1] A vacuum cleaner having a fan driven by an electric motor has a temperature-sensing means arranged in a low-voltage control circuit to switch off the motor if it reaches too high a temperature, e.g. when the dust bag becomes clogged. In one embodiment the sensing means is a bi-metal strip 12 at normal temperatures in electrical contact with a steel spring 13. At higher temperatures the strip 12 bends upwards until the spring 13 is pulled towards a permanent magnet 17 thus breaking its contact with the strip 12. An insulated distance pin 19 prevents this contact being re-made. The magnet 17 is mounted eccentrically with respect to a knob 18 adjustment of which varies the position of the magnet. An additional electric contact 21 may be used to close a circuit through the spring 13 to light an indicator lamp. A knob 23 is used to return the spring 13 to its normal position.

Title: Improvements relating to electromagnetic relays
Inventor: ROMMEL FREDERICK EMIL
IPC: H01H51/22
Filed: 1952-05-29
Abstract: 731,937. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd., and CARPENTER, R. E. H. May 13, 1953 [May 29, 1962], No. 13720/52. Class 38 (5). A one-side-stable polarized electromagnet;c relay comprises a pivoted armature moving in an air-gap in a magnetic structure, the armature being acted on by both a mechanical and the opposing polarizing magnetic force, which forces would both become zero if the armature moved to a plane set at an angle to the central plane of the air-gap, sufficient movement for this being, however, prevented by the configuration of the relay. Thus the armature can make use of the whole of the air-gap while the resultant restoring force sets always in one direction. In a relay of the kind disclosed in Specifications 315,496, [Class 38 (v)], and 559,047, in which armature a mounted centrally on springs s between the pole of polarizing magnets m, m<SP>1</SP> so that one end moves in an airgap between poles l, l<SP>1</SP> energized by winding w and the other end moves between contacts c, c<SP>1</SP>, the mechanical force is displaced by setting the springs at an angle and the magnetic polarizing force is displaced by the poles of magnets m, m<SP>1</SP> lying at different distances from the central plane AB. When the relay is deenergized, the armature rests against contact c under the influence of overriding magnetic force, and when the relay is energized, the armature turns to engage contact c<SP>1</SP> but does not pass through the plane at which the restoring force is zero. Alternatively, the poles of magnets m, m<SP>1</SP> may be displaced along directions parallel to the central plane, from the central pivot of the armature, and the mechanical force is provided by two helical springs asymmetrically arranged with respect to the plane, Figs. 6, 9 (not shown). The relay may be constructed as described in Specification 619,546, but with the poles at different heights, Figs. 7, 8 (not shown). Fig. 10 shows an arrangement in which centrally pivoted armature a mechanically biased by unequally acting springs S, moves in the two gaps between the mutually off-set ends r, r<SP>1</SP> and r<SP>2</SP>, r<SP>3</SP> of pole pieces t, t<SP>1</SP> fixed to the ends m, m of a horseshoe permanent magnet.

Title: Improvements relating to electronic control circuits
IPC: H03K4/41
Filed: 1947-05-22
Abstract: 631,359. Saw-tooth generating circuits. SCOLES, G. J., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 22, 1947, No. 13796. [Class 40 (vi)] In a saw-tooth current generator of the magnetic Miller type the scanning coil is in the anode circuit of a valve and a capacitor and resistor are-connected in a feed-back circuit between the anode and control grid. The anodes of a pair of rectifiers are connected to the plates of the feed-back capacitor and the cathodes to points of fixed potential so that the capacitor is charged to substantially the same amount prior to each sweep and in this way the scan speed is rendered substantially independent of the repetition frequency. Fig. 2 shows a time base circuit in which the feedback network comprising capacitor C and resistors R1, R2 produces a voltage at B which has both a constant component and one which varies linearly with time, thus producing a saw-tooth current through inductor L which will vary linearly with time although the inductor has inherent resistance. Diodes D1 and D2 prevent capacitor C from being charged at the end of the sweep by energy from inductor L by connecting each plate to a point of fixed potential, e.g. as shown to H.T.+ and H.T.-. Diode D2 also shorts resistor R2 during the return stroke and thus reduces the flyback time.

Title: Improvements in the manufacture of synthetic resinous products
IPC: C08J3/12
Filed: 1946-05-09
Abstract: <PICT:0612843/IV(a)/1> Phenolic resins, which become fluid and capable of being poured on heating, are prepared in the form of granules which do not coalesce at normal temperatures by pouring the hot fluid resin in one or more streams into agitated water maintained at a temperature below the melting point of the resin.  The granulated resin may be withdrawn intermittently from a large volume of stirred water, but preferably the molten resin is poured into a small volume of water agitated by the highspeed injection of more water with or without other agitation, and the granulated resin is withdrawn as a slurry with the excess water and filtered off.  The specific gravity of the water may be altered by dissolving inert materials such as methanol or calcium chloride in it.  When a number of resin digesters are used, a single granulating vessel 2 mounted on a trolley 1 may be employed.  The resin formed into streams by pouring through sieve 5 passes through water agitated by jets from a ring water main 7, and the slurry of granulated resin is withdrawn by pump 3 driven by motor 4 and delivered through pipe 10 for filtration.  The water may be cooled and recirculated to control the temperature in vessel 2.  Such an apparatus is employed in example 1, which describes the granulation of a phenol-modified rosin.  In example 2, a Novolak is kept at 130 DEG  C. in a perforated trough, and allowed to run into agitated water of initial temperature 15 DEG C. and final temperature 23 DEG  C., the product being then filtered off.
