The central and outer zones may be subdivided as for example in halves and quadrants respectively. The preferred directions of retroreflection provide a flashing effect when the reflector is mounted on a rotating bicycle wheel. The mounting may be effected by clips, Fig. 7, or snap fasteners, Fig. 20. The front face of the reflector is smooth and the rear face is faceted to provide the required selective reflection qualities. In manufacturing the reflectors a mould for the plastics material is made by clamping together a plurality of hexagonally shaped stainless steel pins into a bundle to form a master element. Nickel is electrodeposited on the ends of the pins to form a mould, the nickel being easily removable from the stainless steel.

Title: Integrated optical modulators
IPC: G02B6/12
Filed: 1975-04-29
Abstract: 1512451 Controlling light SIEMENS AG 29 April 1975 [2 May 1974] 17687/75 Heading G2F  Superimposed optical waveguides 2, 3, Fig. 2, formed at or adjacent a low refractive index substrate 1 are spaced by a low loss dielectric film 5 of low refractive index, at least one guide being of material with a refractive index which varies when an electric field is applied so as to vary the coupling between the guides, and electrodes 4 being provided on the substrate on either side of the pair of guides to provide the field. In a modification, Fig. 3 (not shown), the guides are displaced relative to substrate 1 so that guide 3 lies on the surface thereof. Preferably the guide 3 is field responsive, and the change in refractive index of guide 2 is either zero, small, or in a direction opposite that in guide 3. The last instance may be achieved by using LiNbO 3  guide with oppositely directed c-axes, Fig. 4 (not shown), to give a temperature compensated device with a length half that needed if only one guide is field-responsive. The propagation constants of the guides may be identical in the absence of a field, and there may be complete coupling which is partially or wholly destroyed when the field is applied. The construction of Fig. 5 essentially comprises two devices as in Fig. 2 but with a common upper guide 6 and a common central electrode 4, and provides variable coupling between guides 2 and 3 solely via the guide 6. Preferably guides 2 and 3 are of the same field-responsive material, and they are spaced so that direct coupling between them is negligible. Guide 6 need not be of electro-optic material, and the indirect coupling between guides 2 and 3 may be adjusted by altering the length of guide 6. In a modification, Fig. 6 (not shown), the common guide 6 underlies guides 2 and 3 and is embedded in the substrate. The devices of Figs. 5 and 6 are said to be more tolerant of waveguide dimensions and spacings, and orientation of the electro-optic material, than those of the type shown in Fig. 2, and both are said to be more tolerant than the prior art variable coupling device of Fig. 1, comprising laterally spaced electro-optic guides 3 in a substrate 1 provided with electrodes 4. In Fig. 1 the guide spacing critically affects the coupling, whereas in the present devices the coupling is determined by the film 5.

Abstract: 648,372. Picture telegraphy; light valves. MUIRHEAD & CO., Ltd., and BELL, J. June 13, 1946, No. 17704. [Class 40 (iii)] A picture telegraphy system employs a light valve comprising an optical system which is adapted to provide a beam of light substantially of H-section (or of T-section) which is traversed (e.g. by reflection from a mirror, the movement of which is controlled by means of modulating signals) in a direction parallel with the normally horizontal element of the H (or with the normally vertical element of the T horizontal), and a slot or aperture of H or T shape through which the beam is projected. The slot may comprise a T-shaped portion 1 (Figs. 2 and 3), and two subsidiary portions 4 spaced from the base of the leg of the T by a distance substantially equal to the width of the vertical limbs 5 of the H-section light beam. The T-shaped portion is radiused, as shown at 8 and 9, and the inclination 7 of the portions 4 is made equal to the inclination 6 of the normally horizontal element of the T. The arrangement according to the invention is stated to minimize limitations of prior systems which employ a rectangular beam of light traversed across a suitably-shaped aperture and which give rise to unwanted exposure when the beam is in the zero position and an insufficiently rapid increase of illumination for a small deflection over the range between grey and black tones.

Abstract: 546,084. Dynamos. REYROLLE & CO., Ltd., A., and BAYLES, J. W. Dec. 18, 1940, No. 17822. [Class 35] A generator having a falling characteristic, as for welding, has shunt windings B<SP>1</SP>, C<SP>1</SP> on the main poles B, C, shunt windings D<SP>1</SP>, E<SP>1</SP> on the auxiliary poles D, E, and series windings B<SP>2</SP>, C<SP>2</SP> on the main poles which reinforce the shunt windings, all the shunt windings being connected between the main brushes or terminals of the generator. The auxiliary poles are preferably of larger cross-section than the main poles. When a short-circuit occurs armature reaction tends to increase the flux in the main poles (but is restricted by saturation) and to decrease the flux in the auxiliary poles, so that the voltage drops to a small value necessary to maintain the desired short-circuit current. Series windings D2, E<SP>2</SP> may be provided on the auxiliary poles. The shunt and series windings reinforce one another so, that the transformer effect between them during transient current changes enhances the falling characteristic. For this purpose there should be a greater number of series windings on the main poles than on the auxiliary poles and means may be provided for increasing the leakage flux linking the windings. As shown, the shunt coils are all in series across the main brushes ; in a modification the shunt coils are series-connected pairs connected in parallel across the output terminals. The auxiliary poles may be saturated on open circuit. Specification 495,779 is referred to.
