Abstract: 1476396 Luminescent materials and uses thereof DAI NIPPON TORYO KK 11 Oct 1974 [13 Oct 1973] 44088/74 Heading C4S A white emitting phosphor for black and white TV consists of a mixture of yellowish green-to-yellow emitting Au and Al : ZnS, the Au and Al being in respective amounts of 5 Î 10<SP>-4</SP> to 10<SP>-2</SP> and 2À5 Î 10<SP>-4</SP> g. to 5 Î 10<SP>-3</SP> g./  gram of ZnS, and a blue emitting Ag : ZnS, the Ag being in amount 10<SP>-5</SP> to 10<SP>-3</SP> g./gram of ZnS, the wt. ratio of the Ag : ZnS to the Au, Al : ZnS being 0À70 to 1À30 and wherein the phosphor does not contain Cd. As red emitting phosphor may be incorporated Eu : yttrium oxysulphide, Eu : yttrium oxide, and/or Eu : yttrium vanadate, Eu concentrations and mixing ratios being disclosed. The red emitting phosphor corrects a short wavelength deficiency of a ZnS : Al, Au-ZnS : Ag mix as discussed w.r.t., Fig. 2 (not shown), and also is of a white body colour and corrects the "yellow centre" effect of known (Zn, Cd)S : Ag screens. ZnS : Au, Al may be prepared by firing ZnS with gold chloride and aluminium sulphate and firing at 950‹ to 1030‹ C. in a reducing atmosphere, producing a cubic structure. Brightness and chromaticity x value change with Au concentration (Fig. 1, not shown). ZnS : Ag may be obtained by firing with silver nitrate. Specific examples are disclosed. A white emitting phosphor combination for a colour TV not forming part of the present invention uses a green emitting ZnS : Cu, Al, blue ZnS : Ag and at least one of Y 2 O 2 S, Y 2 O 3  and YVO 4  activated by Eu and in a 3 : 3 : 4 ratio.

Abstract: 444,982. Rotary compressors. BOSCH AKT.-GES., R, 4, Militõrstrasse, Stuttgart, Germany. Feb. 23, 1935, No. 5858. Convention date, Feb. 26, 1934. [Class 110 (ii)] A compressor of the outwardly - sliding abutment type has part of an eccentric shaft 4, supporting the piston 3, cut away at 15 to balance the rotating masses. This portion is covered by a slotted, sheet-metal sleeve 17 to prevent the shaft from agitating lubricating oil contained in a chamber 14. The sleeve is notched at 18 to fit the edges of the shaft. Lubricating oil enters a port 9 and passes through conduits 11, 12, to bearings 13, and then is collected in the chamber 14. Air enters the compressor through a passage 6 and is delivered past the abutment 7 to an outlet 8. The diameter of the shaft 4 is reduced over the sleeved portion so that the sleeve outside diameter is not greater than that of the unsleeved shaft. A spring-loaded disc valve is provided on the outlet side.

[Also in Division H1] A variable current supply is obtained from output terminals 4 by using two transformers A, B whose secondary windings 8 are connected in parallel and whose primary windings 7 are tapped and connected through a multi-contact switch 11 to the mains supply 2. Closure of any one or any pair of the switch contacts energizes the corresponding winding or windings, parallel connection being effected in the latter condition. Members A, B, 11 together with associated condensers and/or resistors are fixedly mounted in a common insulating housing, Figs. 1 and 2 (not shown). In a modification, Fig. 4 (not shown) four transformers of the same or different current rating are used, their secondaries being in parallel and their primaries, which in this case are untapped, being connected to a multi-contact switch so that the transformers may be energized individually or in parallel. Typical current values are given for various switch positions. The arrangement of Fig. 5 provides additional switches 31, 32, 33 for the divided and tapped primary windings of transformers A, B, C, so that each pair of windings may be connected in series or parallel combination according to the value of the main voltage supply 2. These combinations may be energized individually or in parallel as before.

The coin shoot of a coin-freed telephone has a wire spring 18, Fig. 3b, which is pressed back along a smooth pin 19 by a falling coin 20 until the coin closes a spring contact set 12, 13 and comes to rest on a stop 22; any tendency of the coin to rebound and operate another spring contact set is restrained by the spring being forced upwards into a notched plate 11d. As shown in Fig. 5, a coin slot 33 accepts two or more sizes of coins, the largest being gauged by an exchangeable gauge 33a, and the coins rest on an upper stop 37 carried by a lever 35. When a deposit electromagnet 36 is actuated, the lever tilts to withdraw the stop 37, insert a coin insertion stop 33b and insert lower stops 22, 41 into the path of the coins falling down the shoot 50. Each coin operates a spring contact set 39, 42 according to its size and is released to a coin box 49 when the electromagnet 36 releases. A plate 47, Fig. 4, is bent obliquely across the upper part of the shoot 50 and by a wedge effect prevents smaller coins from bouncing in the coin shoot.
