Filed: 1977-03-04
Abstract: 1536821 Photovoltaic generators D S STREBKOV V V ZADDE V A UNISHKOV T A LITSENKO and D V NEKLJUDOVA 4 March 1977 09343/77 Heading H1K A photovoltaic generator comprises a photovoltaic semiconductor device 1 having a rectifying junction 8 formed either between semiconductor regions 6 and 7 of opposite conductivity types or between a semiconductor region and a Schottky metal contact, at least two current collector contacts 5, 11 and a protective area 2 including incident radiation transmitting elements 12 and intermediate layers 14 arranged between adjacent elements 12 to absorb damaging radiation 15. The elements which may be in the form of parallelepipeds, Figs. 3,4 (not shown), are typically of glass with silver coated sides, and are connected by solders or adhesives to the intermediate lead layers 14. For maximum efficiency, the thickness of the device does not exceed the diffusion length of the photogenerated minority carriers. In one example, the protective cover 2 comprises discrete photovoltaic semiconductor converters with intervening absorbing layers 14 which also serve as current collectors; and the photovoltaic device includes discrete, electrically interconnected photovoltaic elements arranged side by side with intervening current collectors 5, 11 and having their rectifying junctions orthogonal to the radiation receiving surface 3. The band-gap of the converters of the cover is greater than that of the device 1 so as to transmit a part of the incident radiation to the device. In the embodiments of Figs. 11, 12 (not shown) an electric field maintained adjacent the radiation receiving surface 3 produces an inversion region 3 orthogonal to the rectifying junction in the semiconductor body. The protective cover 2 of Fig. 18 comprises a bundle of glass strips 12 diverging like a fan adjacent the surface 3, the strips being bonded to each other and to the device 1 by the absorbing layers 14 which also act as current collectors. The photovoltaic device 1 in one example, Fig. 20 (not shown) comprises individual converted elements made of different semiconducting elements so as to be responsive to different parts of the spectrum and the incident radiation is conducted to each of them by a light conducting strip 12.

Patent GB-1097947-A (GB)
Title: Improvements in and relating to the manufacture of aluminium chloride
IPC: C01F7/58
Filed: 1965-03-08
Abstract: Aluminium chloride is produced by contacting a mixture of aluminium particles and liquid TiCl4 at 120-150 DEG  C. with chlorine, either by passing gaseous Cl2 up through the mixture or using liquid Cl2 mixed with the TiCl4. When the temperature is above the b.pt. of TiCl4, 136 degrees, superatmospheric pressure is applied to prevent boiling. Al pellets and hot TiCl4 are introduced into a steam, water or oil jacketed reaction vessel of glass, steel, Ni, or alloy, and Cl2 is bubbled through or introduced in TiCl4, while liquid TiCl4 + AlCl3 is withdraw at the top.  The reaction is carried out under reflux.  Pure AlCl3 may be recovered from its solution in TiCl4 or the mixed halides may be oxidized in the vapour phase to produce TiO2 containing alumina.

Title: An arrangement for the change-over of groups of types in typeprinting telegraphs
IPC: H04L13/18
Filed: 1933-03-31
Abstract: 421,804. Type - printing telegraphs. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. March 31, 1933, No. 9778. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 16, 1933]. [Class 100 (iv)] [See also Group XL] Case-shift mechanism.-In a type-printing telegraph system in which the case of a character is determined by one or more impulses of a signal combination and in which the caseshift is effected independently of the reception of the complete combination of impulses, the change-over from one group of types to the other is effected by a mechanical arrangement operated by a rotating shaft. As shown, a cam 3 on a rotating shaft 2 moves the first selector bar 4 in an anticlockwise direction to a position in which it is latched or released by the armature 5 of the receiving magnet in accordance with the nature of the first impulse which is arranged to control the case group. The bar 4 controls a lever 6 selectively positioning a member 7 with respect to detents 11, 12. During the rotation of the shaft 1, and immediately after the printing of the preceding character, a cam 8 actuates an arm 9 which moves an arm 10 upwardly to engage one of the detents 11, 12 (if a case-shift operation is necessary) thereby releasing a clutch member 13 for half a revolution. An eccentric cam 15 secured to the clutch member 13 is associated with a lever 16 carrying a pivoted horizontal rod 17. When the cam 15 rotates from the position shown an inclined projection on the bar 17 as it moves to the right allows a lever 20 carrying the shaft 22 to drop vertically so that the tape drum 21 co-operates with one of the two rows of type. In a modified arrangement Fig. 2 (not shown), the cam 8 of the arrangement shown causes a selectively positioned interponent to engage one or the other of two bent levers which effect directly the lateral movement of the lever 17 and the consequent vertical movement of the tape drum 21 relative to the type-wheels or rows of type.

Filed: 1932-04-05
Abstract: 389,656. Convertible couplings for railway vehicles. SKODA WORKS, PLZEN, 37n, Jungmannova, Prague. April 5, 1932, No. 9799. Convention date, April 16, 1931. [Class 103 (v).] In replacing a system of non-automatic screw-couplings by automatic couplings, a coupling for use during the transition period comprises the ultimate coupler-head 1 of any desired type, to which is pivoted a second coupler-head 2 designed, when supported in its operative position, to couple automatically with the hook 3 of another wagon or the like, or, when swung rearwardly as indicated in dotted lines, to permit coupling of two automatic coupler-heads 1. Conveniently, a pivoted link 4 may, by engaging alternatively with a recess in the coupler-head 1 or with a hook 5, support the transitional head 2 in its operative or inoperative position. When substituting the new and transitional heads for the old automatic coupling, it may be desirable simultaneously to replace the old side buffers by new buffers fitted with weaker springs. In the construction shown, Fig. 3, the coupler-head 2 is provided with a hook-engaging projection 9 and with a pivoted latch 11 adapted when forced rearwardly by the hook 3 to be locked by a dropping pawl 13 so as to prevent withdrawal of the hook. For uncoupling, the pawl 13 is raised by a pull on a connection 15.

The legs are retained in this position by means of pivoted hooked levers 23, 24 which engage cross pins 13, 18 carried by the legs. Springs 34 acts upon both pins 13, 18 so as to tend to force them apart. For forward movement, the front legs are released by a bar 26. which acts on the lower ends of the hooked levers 23 this lever being moved longitudinally by a hand lever 29. The rider then rocks the horse so that the weight is taken alternately by the front and the rear legs. For backward movement, the rear legs are similarly released

Class 97(1) Apparatus for observing opposite sides of a moving strip comprises two rotating mirror drums, on to each of which light is reflected from the strip by a mirror, the mirror drum being rotated in synchronization with the strip movement. A rocking mirror is associated with each mirror drum so that each side of the strip would be seen by a viewer looking into both rocking mirrors. As shown in Fig. 2, each side of the moving strip 15 is illuminated by lamps 24 and the light therefrom is reflected by mirrors 16, 17 through units 28, 29 to an observer at 20. Each unit may be as described in Specification 754,026 and comprise a mirror drum 32, Fig. 3, which is rotated in synchronism with the movement of the strip, and has associated therewith a rocking mirror 59. An observer of the two mirrors 59 may see a stationary image of each side of the strip. Each mirror 59 is clamped to a rigid member 61 carrying a cam roller 71, which is resiliently pressed against the hub of the associated mirror drum, the latter being geared at 49 to a selsyn motor 53 connected to another selsyn motor driven in synchronization with the drive for the strip 15.
