Abstract: 965,213. Selective signalling systems. ENGLISH ELECTRIC CO. Ltd. Jan. 11, 1961 [Jan. 12,1960],No.1083/60. Heading G4H. Apparatus for measuring the length of a stationary red hot metal plate 10, Fig. 1, comprises a photo-electric device 14 which is rotated about a pivot 15 by a nut 19 on a threaded shaft 21 so as to scan across a measuring station AB, the output of device 14, when excited by radiation from plate 10, as it scans the length CD, enables switching device 30, Fig. 2, to pass the output of a pulse generator, driven by shaft 21, to a counter 28. The pulse generator shown comprises a disc 25 mounted on shaft 21 and having circumferentially spaced holes or reflective areas 27. To prevent errors in measurement caused by variation in the ratio of distances x,y with differing thicknesses of plate 10, e.g. at different stages of a rolling process, a switch 37 is provided and is arranged, at the appropriate thickness setting, to add between 0 and 15/80 ths. of a foot to the length recorded in counter 28 for each revolution of shaft 21. To this end, disc 25 is provided with a further hole or reflective area 36 and four photo-electric devices 35a-35d connected to switch 37 and corresponding respectively to 1/ 10 , 1/ 20 , 1/ 40  and 1/ 80  of a foot. Device 35a may be connected by switch 37 to the 1/ 10  stage of counter 28 and one or more of devices 35b-35d may be connected to respective stages of auxiliary counter 38, the overflow output of which is also connected to the 1/ 10  stage of counter 28. The corrected length measurement is displayed in an indicator 29.

As shown, the T.V. camera 1 has a primary optical system designated by a lens 2 forming an image 10 of the observed object represented by a house 8. An optical image 11 of a scale 6 is superimposed on the image 10 by a system comprising a light source 4, reflector 5, lens 7 and two-way mirror 3. Lens 7 gives a real image of the scale 6 which is converted into a vertical image 9 by the mirror 3, this image being arranged to be in the plane of the house 8 by adjustment of the relative positions of the scale 6 and lens 7. The scale 6 may comprise a perforated opaque plate and be turned about a vertical axis ZZ.

Title: Improvements in or relating to Gas Circulatory Drives for Nuclear Reactors
Inventor: DANIELS GEOFFREY HENRY
IPC: G21C15/24
Filed: 1968-01-10
Abstract: 1,187,691. Cooling reactors. NUCLEAR POWER GROUP Ltd. 18 Dec., 1968 [10 Jan., 1968], No. 1477/68. Heading G6C. A gas circulator drive for a gas-cooled nuclear reactor comprises for each circulator a variable frequency A.C. motor coupled to the circulator, means connecting the motor under normal operating conditions to a mains or an internally-generated electrical supply and, in a situation where the supply fails, is interrupted or is not available, to at least one auxiliary variable frequency A.C. generator adapted to supply electrical power to the motor at a frequency that is automatically varied in response to a fall in load on the circulator. The or each generator is connectable to a group of motors and control means are provided which, on sensing a fault in the normal electrical supply, disconnect all but one of the motors of the group from this supply, start up the auxiliary generator and connect the said one motor to the generator when this has reached a predetermined speed less than full speed (e.g. halfspeed), the control means further detecting the current flow from the generator and subsequently connecting, if required, further motors of the group to the generator in turn as determined by the current flow from the generator. Alternatively, the connection between the motor and generator may be made when the speed of the motor equals that of the generator since the motor may still be running with a falling speed following disconnection of the grid or internal supply. The need for further motors of the group being connected to the generator may arise if in addition to loss of grid supply there is a reduction in pressure in the reactor due, for example, to a leak in the reactor vessel. With a falling pressure, the power required by each motor and consequently the current which they draw falls. When all the motors have been connected, provision must be made to limit the speed of the motors and generators in the event of further reduction in the coolant pressure. This limitation is achieved by setting the governors of the prime movers driving the auxiliary generators to full speed when all the motors have been run to half speed.

Abstract: 514,194. Screw-and-nut lifting-mechanism. GRASSMANN, E. Jan. 16, 1939, Nos. 1484 and 1485. Convention dates, Jan. 18, 1938, and July 4, 1938. [Class 78 (iii)] [Also in Group XXIV] A flexible metal band 5, Fig. 1, is wound from collapsed spiral form into a helix with overlapping coils for use as a supporting or lifting-device or as a lifting-jack. To form the tube a rotor 11, 'with an internally-projecting helical track 27 engaging the lower edge of the band, is operated to raise the band, which is prevented from rotating bodily by projections 7 engaging the flutes 21 on the central fixed cylinder 8. Ball bearings 3 facilitate the rotation. The helical track may be fitted with conical anti-friction rollers 10, Fig. 2, which are joined with play by links and form a support for an endless chain 9 which is slotted or grooved to carry the lower edge of the band. When in tubular form, pins 7 on the edge of the band engage holes in the adjacent convolution and prevent the structure from collapsing axially. The lower edge of the band may be arc-shaped. This is stated to produce a tube of constant diameter able to withstand axial pressure without the use of the pins 7. In the'Specification as open to inspection under Sect. 91 the helix is stated to be applicable for use as a conduit for conveying liquids or gases. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to hydraulic brake and other power transmission systems

Abstract: 502,056. Hydraulic transmission. HYDRAULIC BRAKE CO. Jan. 20, 1938, No. 1972. Convention date, Jan. 22, 1937. Addition to 443,154. [Class 103 (i)] A hydraulic transmission system comprises a low-pressure piston 90 forward of the highpressure piston 48, the pressure being gradually transferred from the lowto the high-pressure piston. The high-pressure piston 48 is formed by a part 54 and a flange 68 formed on a sleeve 76 integral with the low-pressure piston 90. A spring 70 is arranged between the flange 68 and a flange 58 on the part 54. The part 54 is in one with a piston 64 working in the sleeve 76 and carrying a rod 100 having a head 102 fitting in an aperture in the face of the piston 90. When the brake pedal, which is connected to the piston rod 120, is depressed, liquid is forced into the brake pipe lines 36 until the pressure. is sufficient to overcome the spring 70 whereupon the part 54 and the piston 90 approach one another and the head 102 raises the leak-proof cup 112 and connects the spaces in front of the piston 90 to the space 20. The pressure in this space however has been reduced in view of the movement of and the difference in the diameters of the pistons. The parts therefore move back again until a higher pressure is reached in the chamber 22 whereupon this cycle of operations is repeated. Finally the pressure attained is such that the spring 70 is permanently compressed and the space 20 is open to the pipe lines 36 and the braking pressure is exerted by the high-pressure piston which comprises the cups 74, 104 mounted on the flange 68, the piston 64 respectively.
