Patent GB-614071-A (GB)
Abstract: 614,071. Kitchen ranges. SVENSKA AKTIEBOLAGET GASACCUMULATOR. July 1, 1946, No. 19594. Convention date, June 30, 1945. [Class 126] A solid fuel stove has two or more grates disposed at different levels and fed from a common fuel column each having a separate air inlet channel to obtain separate combustion zones which transmit their heat independently to their respective consumption areas. In the form of the invention shown, fuel fed into an upper horizontal grate 2 may reach a lower horizontal grate 3, immediately below it, by an opening 5, Combustion in the upper grate 2 provided with an air inlet 18 controlled by a thermostat 20 with heat sensitive means 21 in the hot plate 6, supplies heat to the hot plate. Combustion in the lower grate 3 provided with an air inlet 22 controlled by a thermostat with heat sensitive means 25 in the oven 16 heats the oven by supplying heat radiation to air in the closed circulation channel 17. Ashes from both grates fall into a common ashpit 4. Pins 11 control the filling of the grate 2 and enable flue gases to contact the underside of the hot plate 6 and a lattice 12 prevents fuel entering the flues: In a modification (not shown) fuel reaches the lower grate 2 by a central magazine pipe. Ashes from the upper grate 2 fall into a separate ashpit and flue gases from the lower combustion zone are collected in an annular channel round the magazine pipe so that they mix with the air supplied to the upper grate.

Title: Prefabricated electrically insulating joint for metallic pipe lines
Inventor: BAGNULO LUIGI
IPC: C23F13/02
Filed: 1969-12-17
Abstract: 1286480 Electrically insulating pipe joint L BAGNULO 17 Dec 1969 [21 Dec 1968] 61452/69 Heading F2S An electrically insulating pipe joint comprises an enlarged socket 3 on pipe end 1 and a flange 4 on pipe end 2, the flange fitting within the socket and being separated therefrom by an electrically insulating sealing ring 6 seated in an annular recess 10 and by the annular space 22, the sealing ring 6 being partially overlapped with a spacer ring 5 of mechanically strong insulating material bonded into a recess 9 in the flange. The joint is held together by a blocking ring 8, screwed or welded into the socket and bearing via insulating spacer 7 on the rear face of the flange 4. The spaces 22, 23 are filled with a hardenable resin and any gas bubbles trapped therein or formed during curing are held at 24. The space 14 may be filled with non-hardening jelly-like material which is inert to the fluid within the pipes and which is non-adhesive. The interior insulating linings 15, 16 of the pipes meet at join 17 so that cracking of the linings does not occur when the joint is stressed. Any seepage through the linings therefore occurs at 17 and is prevented from penetrating the join by the overlap of rings 5 and 6. Further, the retention of ring 6 against radial spread by wall 11 prevents mechanical disruption of the linings 15, 16. The bottom of the socket and the end face of flange 4 may be annularly grooved, and electrodes 18, 19 of inert material, (e.g. platinumplated titanium) may be placed in the walls of the pipes approximately one pipe diameter from the ends of the linings 15, 16 so as to prevent corrosion when electroconductive liquids flow through the pipes. In a further embodiment (Fig. 3, not shown) the ring 7 is replaced by a smaller ring (5<SP>1</SP>) bonded in a recess (9<SP>1</SP>) in the rear surface of the flange 4. The outer diameter of the recess is smaller than the outer diameter of the flange and the ring and flange are partly overlapped by an elastic sealing ring (6<SP>1</SP>) held in an external rebate in the forward end face of plug 8.
Patent GB-735178-A (GB)
Abstract: 735,178. Calculating-apparatus. MONROE CALCULATING MACHINE CO. June 27, 1952, No. 16223/52. Class 106 (1). Differentially - setsable actuators 3 for the totalizer 1 of a calculating machine have an initial idle phase of operation during each cycle (rotation) and are set under key control by the driving means for the actuators during the idle phase of only the first of a plurality of cycles. In the machine shown, each actuator 3 comprises a pair of stepped gears 3a and 3b splined to a shaft 7 and urged outwardly by a spring 12 so as normally to clear an intermediate wheel 5 driving the totalizer. The gears 3a and 3b are differentially adjusted into register with the intermediate wheel 5 by pivoted plates 14, 16, having cam arms 14a, 16a engaged by levers 32 connected through bell-cranks 31 with a pair of differential stopbars 29 for the amount keys 22. The shaft 7 is driven through a train of gears 10 from a main shaft 11. During an initial idle phase of rotation of the shaft 7 and actuators 3, a cam 37, connected by a link 39 with full-cycle locator arms 18 for the main shaft 11, lifts the pivot shaft 33 of the levers 32 so that the stop bars 29 are moved forwardly to engage the stem of a set key and the plates 14, 16 are differentially rocked to adjust the gears 3a, 3b axially relatively to the wheel 5. During continued rotation of the gears, their teeth engage and drive the intermediate wheel. The machine is adapted for repeated cycling by the provision of a toggle 20, which prevents return inward movement of the arms 18 and so retains the gears 3a and 3b differentially adjusted as long as the motor bar is held depressed. Upon release of the motor bar, a hook 21, which is operated by mechanism described in U.S.A. Specification 2,531,207, breaks the toggle lock so that the key-setting is cancelled as the machine comes to rest. Depressed keys are retained by a detent bar 28 engaging over lateral machine comes to rest. Depressed keys are lugs on the key stems. The stop bars are mounted for resilient downward movement against springs 30 and the stops 29a are bevelled at at the rear so that they can clear depressed keys as the bars restore.

Title: Synchronous electric motors
IPC: H02K21/22
Filed: 1978-11-01
Abstract: In small hysteresis motors for use in inertial quality gyroscopes significant dynamic imbalance of the rotor may be caused by random magnetisation of the rotor after each start-up. In the present invention a permanent magnet (5) having pole pieces (6,7) establishes a polarized magnetic field in an air gap (2) between a rotor (3) and stator (1) providing a rotating magnetic field such that the rotor (3) locks into synchronism on a uniquely defined axis of magnetisation. Shunts (8,9) of material having a ferromagnetic Curie point below the running temperature of the motor provide a path for the rotating magnetic field during start and run-up to synchronous speed, a conductive ring (4) producing starting and run up torque. <IMAGE>

Title: Electrical appliances for example electrical heating appliances
IPC: A47J27/08
Filed: 1979-02-05
Abstract: An electrical appliance, which is particularly but not exclusively suitable for domestic heating or cooking of food, e.g. a high-speed cooker, comprises a vessel (1) for containing material to be heated. The vessel (1) incorporates, preferably at its base, an electrically heating assembly (5) having electrical terminals (9, 11) projecting therefrom. When the vessel (1) is inserted in a predetermined orientation in a cavity (6) in a base unit (7), the terminals (9, 11) are electrically connected to corresponding terminals (10) in the base unit, by manipulation of a rotary switch (14), for energisation of the heating assembly via suitable electrical control circuitry in the base unit (7). The base terminals (10) are located within respective spaced recesses (17) in the switch (14) for rotation therewith between an inoperative position in which contact between respective terminals (9, 11, 10) is inhibited but respective ones of the vessel terminals (9, 11) can enter the respective recesses (17) on correct insertion of the vessel (1) into the cavity (6), and an operative position which, if reached after the inoperative position with the vessel (1) correctly inserted, establishes electrical contact between respective terminals (9, 11, 10).
Patent GB-2042790-A (GB)
Title: Conical scanning X-ray tubes
IPC: H01J35/14
Filed: 1979-02-20
Abstract: In conical (e.g. part conical) scanning X-ray tubes, space charge dispersion over the long throw (about 1.5 m) disturbing focussing is countered by magnetic fields from conical coils (11, 12) around and inside the tube cone 14. To reduce the current required in such coils it is proposed to use a beam 5 which travels at a relatively low velocity for at least three quarters of the distance from the electron gun 4 to the X-ray target and to accelerate it to a higher velocity before impact on the target. The extra acceleration potential is divided across metal rings 13 set in ceramic or glass inserts 14. Beam cross-section may be circular or ribbon shaped, the latter being maintained radial to the target by rotation of the gun or the beam shaping part thereof, or by a rotating field system. The transverse component of the beam due to thermal emission velocity, space charge repulsion and field aberrations is discussed. Computerised tomographic applications are exemplified. <IMAGE>
Patent GB-2022530-A (GB)
Title: Improvements in or relating to aircraft
IPC: B64C23/06
Filed: 1979-03-28
Abstract: An aircraft wing of low aspect ratio and approximately triangular plan- form (ie delta) has flaps 2 mounted on its upper surface approximately parallel with the leading edges and beneath the vortices formed at moderate and large angles of incidence. The flaps are raised substantially normal to the wing surface to reduce the drag coefficient, partly by increasing the lift coefficient at a given angle of incidence and partly by thrust forces generated on the flaps themselves. Hence a lower incidence is sufficient to provide required lift. Increase in lift is derived from an increase in lateral spacing of the vortices and thrust forces from the large outflows induced by the vortices above the wing which acts to convert the forward facing flap surfaces to suction surfaces. These outflows separate at the high-swept edges of the flaps to form other vortices rotating in opposite senses to the primary vortices. The flaps retract flush with the wing surface when not required. <IMAGE>
