Title: Improvements in or relating to spectrometry
IPC: G01J3/28
Filed: 1962-09-14
Abstract: 1,020,562. Photo-electric spectrometers. BLOCK ENGINEERING Inc. Oct. 24,1961 [Sept. 14,1962],No.35108/62. Heading G1A. [Also in Division G2] A prism spectrometer Fig. 1 (not shown) has a member G1 forming a plurality of entry slits in one plane and a member G2 forming a plurality of exit slits also arranged in one plane, and the entry and exit slits are imaged upon each other and are synchronously rotatable about an axis perpendicular to the direction of dispersion so as to vary the slit opening in the direction of dispersion. In this way, the transmission characteristic of the prism spectrometer can be made to resemble that of a Michelson or other interferometric spectrometer. As shown in Fig. 5, a disc G4 consisting of parallel strips, alternately opaque and transparent, provides the entry slits for light which is dispersed by a prism and reflected by a Littrow mirror 48. Disc G4 is imaged upon itself so as to form also an array of exit slits. A motor 43 drives the disc G4 relatively to entry and exit pupils 51, 52. Preferably, the chopping frequency for each wavelength should be kept constant; that means that the rotation of the disc G4 should be non-linear with time. Such rotation may be provided by an arrangement in which a shaft 41.1 (Fig. 6, not shown) drives the disc G4 and carries a bar 197 with a slot 108 in which rides a pin 116 carried by a slider 114 forming an extension of a crank 110 on shaft 41.2 and riding on the surface of a fixed cam 120, the shaft 41.2 being motor driven. Shaft 41.1 may be fast with the disc G4 or may drive a pinion meshing with a toothed edge on the disc.

Abstract: 877,450. Converting. BURKE, J. D. Oct. 25, 1957 [Nov. 22, 1956], No. 35730/56. Class 38 (2). In the E.H.T. supply to the C.R.T.10 in a television receiver which includes a rectifier valve 3 connected to a line transformer 4, the heating current of the valve cathode 8 derived from transformer winding 6 is controlled in accordance with the value of the C.R.T. beam current to compensate for the variation of heater current resulting from voltage changes as the beam current varies. An inductor 14 in the heater circuit is varied in value by movement of a magnetic core 15 by a coil 18 connected at A, B or C to carry the beam current. The core may be moved against a spring or gravity. Alternatively, inductor 14 may be replaced by a choke 26 having a core 25 saturable by the current in coil 24 connected at A, B or C, a permanent magnetic bias 27 also being provided, Fig. 2. The two effects may be combined, Fig. 3 (not shown). In modifications, the inductor may be replaced or associated with variable resistors or capacitors, or the coupling of winding 6 to transformer 4 may be varied by a moving vane. The heating current may be varied by control of a valve by the bias voltage of C.R.T.10 (Fig. 5, not shown). Connection of the control winding at A allows the whole compensating arrangement to be at E.H.T. potential and coil 18 may be mounted on the transformer or the rectifier valve base.
