Title: Burner assembly
IPC: F23D14/46
Filed: 1978-07-17
Abstract: Burner assemblies for, e.g. blast furnace or coke oven gas, can suffer from deposit build-up in fuel inlet ducts the manual removal of which is not usually feasible. Such deposits can at least be reduced by cleaning with, e.g., saturated steam directed through nozzles located in the duct upstream of, and directed towards, the outlet end thereof. An annular duct has an annular sectionalised distributor 50 in which nozzles 52 are located and directed towards the duct outlet. Fluid is selectively fed to the distributor sections by valve means 54, 56. The cylindrical duct can have a straight distributor 100 having nozzles 102 disposed helically thereof (Figure 5 - not shown). Optionally, other nozzles 60, 62, 64 are directed against specific surfaces of the duct (Figure 3 - not shown). <IMAGE>

Title: Control systems for multiple gas turbine-generator units
IPC: F02C9/00
Filed: 1978-09-15
Abstract: A control system for multiple gas turbine-generator units 12 comprises a local control computer 14 which computes a maximum permissible output for each gas turbine-generator unit independently as a dynamic function of combustor shell pressure and exhaust temperature in that unit and the output thus obtained is transmitted to a central control 16. Load demands calculated for each unit are dispatched from the central control to individual local control arrangements 18 which respond to control their respective gas turbine- generators in a manner not to exceed the respective maximum output. Each turbine control 14 sets its generator output at a preset level which is modified by load change signals from the central control 16 and each control 14 operates its turbine fuel control to satisfy the load demand. <IMAGE>

Title: Photographic shutter
IPC: G03B9/22
Filed: 1978-12-21
Abstract: The shutter has more than two shutter sectors 5, 6, 7, 8 actuated by a common transmission element 2 which moves to and fro rectilinearly, as a result of which low moments of inertia are achieved and a reliable actuation can take place. As shown, four sectors 5 to 8 are pivoted to a baseplate 1 by respective pins 3, 4, 9, 10. The sectors are actuated by pins 11 and 12 fixed to the transmission element 2. In Figs. 3 and 4 (not shown) four sectors are pivoted to a baseplate by two pins (14, 22) and are actuated by four pins (20, 21,23, 24) fixed to a transmission element (15). <IMAGE>

Title: A piezoelectric voltage generator
IPC: F23Q3/00
Filed: 1979-02-14
Abstract: An insulating case 28 contains a piezoelectric element 26 secured between steel blocks 25, 29, and an axially movable percussion hammer 23 which is spring urged towards the piezoelectric element.

Patent GB-2020012-A (GB)
Title: Strain and displacement measuring gauges
IPC: G01B11/16
Filed: 1979-04-12
Abstract: A strain or displacement gauge has two blocks between which movement is measured; a fibre optic light path 2 is provided into the gauge and another fibre optic light path 4 is provided out of the gauge. The change in intensity of light transmitted along the path is a measure of movement between the blocks. A light source 1 supplies light to the gauge along path 2 and an optical detector 3 detects the light received along path 4. A light path can be provided in each block with the paths aligned with each other and movement between the blocks causes misalignment between the paths. Alternatively a shutter or attenuator or a device having markings (for digital measurement) can be interposed in the light path by an amount depending on the movement between the blocks. Sets of fibres may be used to give a vernier effect, and two dimensional measuring is possible. If each block carries a grating, Moiré fringes may be used to measure the movement. If the movement is arranged to rotate the polarisation of the light, this may be used to measure the movement. <IMAGE>

Filed: 1979-05-16
Abstract: In a watch case (5) one side of which is provided with a watch glass (8) and which has a sound-producing device (6) mounted therein, the said side of the watch case having an aperture (5a) through which sound from the device (6) may be transmitted, a support member (2) is mounted on the said side of the watch case and has a portion (2a) which is fixed in the said aperture (5a), and a foil or plate (1) which is visible from the exterior of the watch is mounted on the support member (2), the foil or plate (1) being fixed to the support member (2) by at least one pin (3). As described the foil or plate (1) is in the form of a frame and surrounds the glass (8), covering a gasket (7). Its one edge has an aperture (1d) to let out the sound from the device (6), and its other edge is held to the case (5) by further pins (4). A number of decorative forms of the foil are suggested. <IMAGE>

Title: Rail fastener assembly
IPC: E01B9/48
Filed: 1979-05-25
Abstract: A rail fastener assembly includes a base plate (12) and at least two rail locator members (48) which are formed integrally with the base plate to be located on opposite sides of the rail (R). There are also at least two clip holders (30) formed integrally with said base plate (12) and a resilient clip (38) associated with each said clip holder (30) for engaging the base flange of the rail (R) to secure the rail in place. The clip holders (30) each include an aperture (36) through which the substantially planar clip (38) extends. A pair of integral legs (44) of each clip holder is of height relative to the aperture (36) so as to provide for flexing of the associated clip between them the aperture and the rail, about the fulcrum provided by the upper wall (34a) of the aperture so that the clip (38) is biased into engagement with the rail (R). Shoulders (46) formed on the legs (44) serve for approximately positioning the associated clip (38). <IMAGE>
Patent GB-2058479-A (GB)
Title: Brushgear in a compact electric motor
IPC: H01R39/40
Filed: 1979-09-03
Abstract: A holder for a brush 25 in an electric motor comprises a piston 23 which is free to slide within a cylinder 21; the piston moves in the same direction as that in which the brush moves e.g. in response to vibration or shock generated in the motor, or in following an unevenly worn commutator surface; and the piston 23 acts on a fluid 26 to apply a force to a further piston 24 which is attached to the brush 25, the force opposing the movement of the brush. In other arrangements (not shown), a piston (511 Fig. 5 or 613 Fig. 6) and a fluid provide a coupling between the brush holder and the motor frame; a piston (714, Fig. 7) attached to a brush (75) reacts with fluid in a small gap (715); a large diameter pressure spring (83) is used; a spring (91, Fig. 9) surrounds a brush (92); co-axial pistons, one (107 Fig. 10) within the other (105), are used. Two important problems for electric traction motors are limited space for sufficient power, and uneven wear of the commutator. Accordingly it is described how a re-arrangement of the commutator can facilitate more compact brush holder design to give greater length of armature on the same length of rotor shaft. It is then shown how the brushes can be balanced to negate the effect of their own inertial responses to vibration and shock, and reduce the largest factor of uneven commutator wear. Various designs are suggested, to cover a range of installation limitations and various service advantages. Figure I in the specification shows how, with the methods described, motor winding space can be increased within the same size motor frame. Figure 3 then describes by means of 'electrical analogue', the dynamic function of the inertial balancing mechanism, and Figure 10 shows a 'fail-safe' embodiment of such mechanism. <IMAGE>
Patent GB-2034003-A (GB)
Title: Shaft Coupling Assemblies
IPC: F16D1/06
Filed: 1979-10-29
Abstract: An end portion 6 of a first shaft 2 is provided with a flat 10 parallel to its axis and an end portion 12 of a second shaft 4 has an axial cylindrical bore 16 for receiving the end portion of the first shaft. A spring 24 is held in transverse recesses 20, 22 in the second shaft, and has a curved portion 30 which is engageable with the flat 10 to prevent relative rotation between the shafts. The spring may however serve to absorb torsional shock loads. This construction renders unnecessary the provision of a bore of D-shaped cross-section, or of a transverse clamp screw, as in some prior assemblies. <IMAGE>
