Title: Improvements in or relating to gun fire control systems
IPC: F41G5/02
Filed: 1920-01-13
Abstract: 160,977. Vickers, Ltd., and Watt, G. E. Jan. 13, 1920. Methods of sighting.-Consists in apparatus for deflecting one or more naval guns in azimuth relatively to the line of sight of a distant sighting apparatus, to correct for inclination of the gun trunnion axis due to rolling of the gun plat. form across the line of fire. The distant sighting telescope A, Fig. 1, is carried by a sector a<1> copivotal with a sector A<1>, which is rotated in accordance with the range indicated on a drum A <4> by operating a hand-wheel A<3>. The telescope is maintained on the target by actuating an elevating hand-wheel a<3> and a training hand-wheel B. The training movement is communicated through one element of a differential gear C to a transmitter switch C<1> serving to transmit the training angle to the gun. This angle is corrected, prior to transmission, for inclination of the gun platform, by a device which is controlled by the range wheel A<3> and a hand-wheel f<1> operating a crosssighting telescope H<1>, Fig. 3, and which acts through the other element of the differential gear C. The operation of the range wheel A<3> deflects a guide G pivoted at g<1> to a frame E through an angle proportional to the range. The operation of the wheel f<1> to maintain the sight H<1> directed on the horizon displaces a block F slidable vertically on the frame E by an amount proportional to the defined angle of roll of the platform. A roller d', Fig. 2, engaging the guide G and carried by a rack d<2> slidable horizontally in the block F, is thus displaced by an amount proportional to both these quantities, and its displacement is imparted by the rack to a pinion d<1> feathered on a shaft D' which imparts the correction through the gear C to the transmitter switch C'. The Provisional Specification states also that the crosssighting telescope may be of the periscope or reflecting mirror type. Reference has been directed by the Comptroller to Specification 146,483.

Title: Systems for converting light energy into electrical energy and vice-versa
IPC: H04N5/14
Filed: 1928-01-16
Abstract: 288,237. Electrical Research Products, Inc., (Assignees of Mohr, F.). April 6, 1927, [Convention date]. Copying-telegraphs; television. - Relates to television apparatus, copying telegraphs, optical phonographs and like apparatus in which a picture or record is scanned by an aperture moving relatively thereto, and comprises means for eliminating the blurring which arises from the finite width of the aperture. Thus in a television transmitter, Fig. 1, in which the optical projection of a film 1 illuminated by a lamp 2 is analysed by a disc 3 having spirally arranged apertures 3<a>, Fig. 1<a>, the current taken from the photo-electric cell 4 is proportional to the average illumination extending over the picture-element corresponding to an aperture 3<a> and consequently represents a blurred image. The invention is based on the following analysis : the horizontally moving aperture is regarded as made up of elementary vertical strips, each of which controls an elementary fraction of the photo-electric current which, for a definite scanning-speed, is a function of time. This function is the same in form but different in phase for different elementary strips, and the current due to the whole aperture is obtained by integrating across the aperture, with respect to phase. It is shown that, when the integration is carried out for each of the Fourier components into which the function may be resolved, the result depends on the width of the aperture, the wave-length of the component, and other factors : so that the finite size of the aperture differently affects different components. The blurring of the transmitted picture is attributed to this fact. The invention consists in the interposition of a filter 8 between the photo-electric cell 4 and output terminals a of the transmitter, and in a similar arrangement at the receiver, the filter being so calculated as to equalize the effect of the size of the aperture for all components. A single filter may compensate for the double distortion arising at the transmitter and the receiver.

Filed: 1976-01-15
Abstract: 1516221 Guides comprising opposed roller-sets SCHLOEMANN-SIEMAG AG 15 Jan 1976 [29 Jan 1975] 1581/76 Heading B8A [Also in Division B3] Alternate rolls 6, 6, Fig. 6, of a train of pairs of opposed rolls for guiding a strand are offset alternately by one side or the other of the strand path so that the width (b) of the path is defined by the outermost extremities of the working portions of alternate rolls and is greater than a working portion length. Idler rolls may be mounted in gaps at the sides of the strand path where the rolls have been offset. The rolls can thus be shorter and therefore thinner so that the casting speed can be increased. The length of a roll working portion is equal to or greater than the maximum slab width minus the distance t between the axes of adjacent rolls. Rolls on opposite sides of the strand path are also laterally offset relative to one another. The guide rolls of some of the pairs are each carried in bearings 22, 23 mounted on a crossmember 17, Fig. 2, and these members on one side of the path may be individually mounted so as to be displaceable towards and away from the strand surface, but as shown and particularly in the upstream part of the guide train, a number of cross-members 17 are grouped and connected by two end pieces 16 which are so displaceable while lower cross-members 14 are connected by two fixed end pieces 13. A pillar 12 secured to each end piece 13 by way of a holder 11 guides a sleeve (15) attached to the corresponding end piece 16 and bears an hydraulic cylinder 18 whose piston-rod is secured to the holder 11 for adjusting the roll spacing which is maintained by spacers 19 between the holder 11 and sleeve (15). The rolls of the downstream part, Figs. 1, 4, 5 (not shown), are of larger diameter and withdrawn and straighten the strand. The cross-members are individually mounted.

A circuit for controlling the controlled rectifiers in a converter supplying a polyphase synchronous machine comprises a respective logic circuit RA ... TC adapted to be connected to the triggering electrode of each rectifier 1 . . .  9, the logic circuit only providing an output when it receives signals simultaneously from two shift registers 23, 25, the arrangement being such that each rectifier is switched in dependence on the voltage of the phase of the supply to which it is connected and on the position of the rotor of the machine. In controlling the three phase machine 11, shown, using a converter having rectifiers arranged in three groups of three 1, 2, 3 and 4, 5, 6 and 7, 8, 9, the shift register 25 receives input signals from a position sensor 24 and has as many outputs as there are phases in the machine, in this case three, and the shift register 23 has as many outputs as there are rectifiers in each group, in this case also three, and receives input signals from a polyphase signal generator 22 which produces in each of its outputs a number of pulses per second numerically equal to the supply frequency. Thus each group of rectifiers is controlled by register 25 to conduct for 120 degrees and during that conduction period a different one of the rectifiers in the group conducts at different times in dependence on register 23. A regulator 21 supplies a D.C. voltage to pulse generator 22, serving,to delay the output pulses of generator 22 and thus regulates the voltage fed to the synchronous machine.
