Title: Electric commutator or slip-ring brush
Inventor: LYDDON PERCY EDWARD
IPC: H01R39/24
Filed: 1955-05-27
Abstract: 832,903. Brushes for dynamo-electric machines. MORGAN CRUCIBLE CO. Ltd. May 25, 1956 [May 27, 1955; Aug. 31, 1955], Nos. 15414/55 and 25029/55. Class 35. In a split brush in which the brush-parts are not secured together, at least one part has a cap of different resistance so that the brush provides paths of different resistance. As shown in Fig. 3, two brush parts 11, 12 are provided with caps 21, 22 of different material mutually insulated by a strip 45. The parts may be pressed by a single spring 3, as shown, or by separate springs. Modifications have caps to which the brush parts make contact on oblique surfaces, the caps being recessed to prevent contact with the centre portion. In a further modification, Fig. 6, the cap 25 is extended down between the brush-parts 11, 12 to form a central brush-part. If desired additional caps of differential resistivity may be inserted at the top of the partbrushes 11, 12. A single part-brush in addition to the extended cap may be used so that the cap is L-shaped instead of T-shaped. Two partbrushes may be on the same side of this L-shaped brush. In Fig. 14, only the brush-part 12 has a cap 22 bonded to it. The flexible pigtail 31 may be connected to the brush 11, as shown, or to the cap 22, or to both. Two capped brushparts may be used, thus producing a triple brush. Fig. 11 shows how the brush part to which the pigtail 31 is attached has a step X so that both parts may be pulled up simultaneously. A modification is described in which the cap-part covers more than one brush-part, and pigtails are connected to the cap and a brush-part. The caps may be of graded resistance. Specification 832,904 is referred to.

Abstract: 1,151,741. Solid fuel fired stoves. RADIATION Ltd. 17 May, 1966 [14 April, 1965], No. 15993/65. Heading F4W. In a closed solid fuel stove of the fuel magazine type in which producer gas is generated by the passage of air through a fuel bed in the combustion chamber 1, downdraught air enters the combustion chamber by an inlet 11a from a duct 11, and cutting air to restrict the height of the incandescent fuel bed by an inlet nozzle 17 leading from a duct 12. The producer gas generated burns at the top of a collecting chamber 32 with the aid of secondary air at a nozzle 14 adjacent the combustion chamber outlet 14a and supplied via ducts 10, 13 from a port 19. A further port 18 supplies the ducts 11, 12 and also a duet 9 supplying primary air to a space 5 below the grate 3. The producer gas burns at a nozzle 24 in a refractory platform 23 supporting a radiant 22 in a chamber 28 leading to a flue outlet 30 and closed by a window 21 of heat resisting, impact resisting glass or similar material transparent or translucent material. In a modification, the ducts 10, 13 are omitted and secondary air is supplied in an upwardly inclined direction from a manifold below a front window composed of horizontal glass rods. The duct 9 is also omitted, primary air being supplied by the cutting air inlet which is restricted by a lip. The combustion chamber walls may be lined with cement and taper upwardly at an angle of about 6 degrees. The downdraught air inlet may lead directly into the top of the fuel magazine. The radiant may be dispensed with and a blower may supply the primary, secondary, or other air to the stove.

Abstract: 388,622. Lay figures. LEWIN, A., 38, Windscheidstrasse, Charlottenburg, Berlin. June 6, 1932, No. 16001. [Class 52 (v).] An adjustable model for trying-on garments has the body portion composed of flexible wires interconnected to form a large number of substantially square meshes, flexible connecting elements which retain their shape after bending being provided between the meshes. Meshes 1 .. 4, Fig. 1, of flexible wire form the detachable portion of the model which is adapted to be moulded to the shape of the body. The connectons 5 between the meshes are also flexible and may each be formed by loops 7, Fig. 8, held together by a binding of wire and surrounded by a sleeve 9 provided with a hole 10. Alternatively, these connections may be formed by eyes movable in a friction ring or by a chain connection surrounded by a ring. According to a further alternative the mesh wires may be bent together in undulated shape, as shown by Fig. 10, engagement being maintained by sleeves 15. To retain the shape of the model while trying on a garment the network is reinforced by extensible stays which may be mounted on a stand. Fig. 3 shows such a stay composed of relatively-movable tubes 18, 19, and elastic lug 20 fixed in the tube 19 projecting into the tube 18. In a modified form of stay a nut fixed within the tube 18 engages with a male thread on the tube 19. Alternatively, the tube 19 may be provided with a resilient projection which may engage with one of a plurality of holes in the tube 18, or the tube 19 may carry a clamping screw which extends through a longitudinal slot in the tube 18. The stays may also be constructed in the form of lazytongs.

Title: Current-source arrangement
IPC: G05F3/26
Filed: 1975-04-18
Abstract: 1479535 Transistor current sources; digitalto-analogue conversion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 April 1975 [23 April 1974] 16079/75 Headings H3T and H3H A source of n accurately identical currents comprises a source of n approximately equal currents and a coupling circuit having n inputs respectively receiving the n approximately equal currents, and n outputs, the coupling circuit receiving a clock signal whereby it permutatively connects each input to each of the outputs in turn during a cycle of the clock signal. Nominally equal currents I 1 , I 2 , I 3  from a current mirror S, Fig. 1, are applied to the inputs P 1 , P 2 , P 3  of a coupling circuit T. Three phase control signals from a clock G and distributor F open gating transistors 5, 8, 11 then 6, 9, 12 and then 7, 10, 13 so that each output Q 1 , Q 2 , Q 3  receives the currents I 1 , I 2 , I 3  in turn. The output currents I 1 <SP>1</SP>, I 2 <SP>1</SP>, I 3 <SP>1</SP> when smoothed by filters L 1 , L 2 , L 3  are more accurately equal than I 1 , I 2 , I 3 . In order to produce a series of currents in the ratio 1, 2, 4, 8 ... for use in a digital-to-analog converter a number of current sources with n = 2 are cascaded. A first output of each source provides one of the output currents and the second passes to the next current source to be divided into two halves, Fig. 3 (not shown). Inaccuracies due to base current in the switching transistors may be avoided by connecting a similar transistor in series in the first output with its base connected to the second output, Fig. 7 (not shown). This is not necessary when field effect transistors F.E.Ts) are used for switching. Such a cascade of current sources is in series across the power supply; if more sources are required than the available supply voltage can cope with, they can be arranged in two or more parallel cascades linked by current mirrors, Fig. 6 (not shown). The current mirrors may also embody the invention, Fig. 5. The transistors 41, 42 are controlled by a F.E.T. amplifier 47 to produce currents substantially equal to that applied at the input Q 31  of the current mirror. The coupling circuit T 3  ensures that the output at Q 32  accurately mirrors the input.
