A supplementary lens attachment for a photographic camera comprises, in a single housing 7, Fig. 1, two lenses capable of forming an afocal system and a range-finder coupled to one of the lenses, the coupled lens being adjustable along the optical axis of the objective. The objective 2 to which the attachment is secured is focused for an object at infinity and objects at finite distances may then be brought into focus by adjusting the range finger on them. Preferably, the lenses 9, 10 are of equal and opposite power so that the system is afocal when they are touching. The lens may consist of two entirely separate components forming a Galilean system or an inverted Galilean system for telephoto or wide angle effects respectively. As shown in Fig. 1, lens 10 is movable through screw-threaded engagement of mounting 16 with member 13 attached to housing 7. A member 18 secured to mounting 16 is provided with a knurled edge 19 and an eccentric cam track 23 on which pin 24 rides and tilts mirror 27 of a coincidence-type short home base range finder. A fixed half-silvered mirror 28 is provided. In another form clamping ring 3 can be changed to fit different cameras and a separate cam track member is provided which does not move axially with member 18. Stops are also provided to limit the rotation of mounting 16. In a similar form the base of the range finder is arranged horizontally. As shown in Fig. 9, objective 87 is coupled with lens 10 and forms a sharp image on ground-glass screen 78 when the camera is in focus. The focal length of objective 87 may be numerically equal to that of one of the lenses 9 or 10. When lens 9 is adjustable the motion imparted to objective 87 must be reversed.

Abstract: 989,312. Amplifying circuits employing transistors. JOSEPH LUCAS (INDUSTRIES) Ltd. Feb. 20, 1964 [April 10, 1963], No. 14287/63. Heading H3T. In a D.C. amplifier of the chopper-modulator type employing transistor switches as the modulating and demodulating choppers at the input and output respectively of an A.C. amplifier, the modulating chopper comprises two transistors 17, 18 of opposite conductivity types connected in parallel across the input to the A.C. amplifier 12 so that transients produced by a transistor of one conductivity type tend to be cancelled by the other of the opposite conductivity type. Push-pull switching signals are applied to the bases of the transistors through terminals 21, 25 and a switching signal in phase with that applied to terminal 25 is applied to the base electrode of the demodulating transistor 19. In order to improve the compensation, a bias voltage may be applied from network 31, 34 to the base of whichever transistor produces the smaller transients to increase the transients it produces so that they become more nearly equal to those produced by the other transistor. Diodes 23, 27 prevent excessive reverse bias being applied to the bases of transistors 17, 18 and the tapping point on resistor 16 is adjusted to provide zero voltage between the tapping point and the collectors of the switching transistors. The demodulating transistor 19 may be replaced by a circuit similar to that used at the input to the amplifier.

Abstract: 318,090. Barnes, R. S., Harris, J. E. G., Wylam, B., Thomas, J., and Scottish Dyes, Ltd. May 22, 1928. Leuco derivatives of 3:4-phthaloyl-7:8-benzacridone, sulphuric acid esters of.-The dye, i.e. Caledon Red BN, is treated with pyridine sulphurtrioxide or substances capable of yielding this body with pyridine in the presence of copper in tertiary basic suspension at a temperature above 80‹ C. and preferably about 90‹ C. to give water soluble, stable sulphuric acid ester derivatives. These may also be obtained by treating the dry leuco-compound of the dye with pyridine sulphur trioxide in tertiary basic suspension at a similar temperature. In this latter case it is' advantageous to exclude air from the melt by working in an atmosphere of an inert gas; otherwise the presence of copper is preferable. The ester derivative may be extracted as an alkaline salt by adding aqueous alkali to the melt, distilling off the base in vacuo and salting out after filtering. The paste may be dried for example as described in Specification 288,358. Pyridine sulphurtrioxide, pyridine with chlorsulphonic acid, methyl chlorsulphonic acid, and potassium pyrosulphate are the esterifying agents employed in examples which describe the process applied to the dye and its dry leuco-compound. Other bases such as dimethylaniline may less advantageously replace pyridine as diluents. These products may be dyed or printed onto cotton and other fibres and developed thereon with acid oxidizing agents such as dilute hydrochloric acid or copper sulphate with hydrochloric acid. Dyeing is preferably carried out in the cold from an aqueous solution, and the subsequent oxidation is carefully controlled, especially in the case of wool, to avoid the formation of brown shades which may also appear when certain oxidizing agents, such as nitrous acid, are employed. Specifications 245,587, 247,787, 251,491, and 258,626 are referred to.
