Abstract: 496,588. Endless - belt conveyers. COOCH, J. F. June 8, 1937, No. 15892. [Class 78 (i)] An endless-belt conveyer, more particularly for the sorting of potatoes, &c., has the carrying surface of the belt formed of a plurality of parallel rollers 5 which rotate during the movement of the belt so as to turn the potatoes over and expose all their sides to inspection. The rollers may be plain or fluted, and are mounted in bearings 10a carried by two parallel endless chains 10 running over sprocket wheels 12, 14 on two parallel shafts 13, 15. The shaft 15 is power-driven, and the shaft 13 is carried in sliding bearings 19a adjustable by screws 21a to keep the chains 10 taut. The upper load-carrying span of rollers ride on run-ways 8 located at the ends of the rollers and, if desired, intermediately. On one or both of the outside run-ways is a stationary rack 7 meshing with a pinion 6 on one or both ends of the rollers, and effecting positive rotation thereof. The lower span of rollers is supported by a medial rail 22. The potatoes enter by a feed-board 3 and are delivered through a shoot 4 into sacks, &c. suspended by hooks 4a.

Title: An improved process for increasing the stability of solid sugar, more particularly starch sugar
IPC: C13K1/10
Filed: 1927-06-15
Abstract: 297,338. Mautner, H. June 15, 1927. No Patent granted (Sealing fee not paid). Sugar preparations.-A process for the preservation of sugar consists in permanently incorporating ethyl alcohol in the sugar mass, a dry, solid product being obtained containing chemically unchanged ethyl alcohol in such amount that the crystals do not become wet. Ordinary crystallized starch sugar may be re-crystallized from alcohol, or a normal starch sugar solution may be thickened and mixed with ethyl alcohol, seed crystals of the same origin being added and the mass stirred and left to solidify. The process is applicable to crystallized invert sugar, levulose, maltose and also to sugar solutions mixed with flavouring materials. Volatilization of the alcohol is prevented by coatings of chocolate, icing sugar, fondant paste, tragacanth or gelatine, or by moulding under pressure so that the surface of the sugar melts and forms a non-porous coating.

Abstract: 460,355. Impedance networks. SIEMENS & HALSKE AKT.-GES. June 13, 1936, No. 16547. Convention date, June 14, 1935. [Class 40 (iii)] A network is so designed that its phase constant varies with frequency while both its characteristic impedance and its attenuation constant are independent of frequency. In the case of a lattice network having line and lattice impedances R1' R2, or an equivalent bridged-T network, Fig. 2 (not shown), the impedances R1, R2 must be inverse since the characteristic impedance Z is real and equal to #(R1R2)' and in order that the attenuation constant may be independent of frequency the impedance R1 is, according to the invention, given the forms (C1 + jd1#) /(C2 + jd2#) where # is a function of the frequency and C1d1/C2d2=Z<2>. A form of R1 for which # is equal to the pulsatance p is shown in Fig. 3, where W<2>R/ (W+R)=Z<2>. A form of R1 for which #= (pL - 1 /pC) is shown in Fig. 4, where the five impedance elements are connected by a single equation, and R, R<1> may be the resistances inherent in the reactances. R1 having been chosen, R2 is given the form inverse to it.

A fluid seal arrangement for a shaft 14 rotatable in a housing 10 whose inner wall 11 defines a fluid pressure chamber 12 comprises a shaft-mounted flange 16 having an annular seal face 108, an axially movable seal member 24 mounted within the housing 10 and dividing the chamber 12 into a seal ring chamber 13 and a seal inlet chamber 15, and means 120, 122 for adjusting the fluid pressure within the chambers 13, 15, including control means, Fig. 2 (not shown), responsive to the fluid pressure in the inlet chamber 15 for maintaining a differential pressure across the seal member 24 to hold it out of rubbing contact with the flange seal face 108. Respective annular faceplates 22, 26, e.g. of ceramics, maybe attached to the flange 16 and member 24 by clamping screws 88, spring washers 90 and rings 84, 86, a seal face 106 cooperating with the face 108 to define a tapering fluid seal gap leading to a low pressure region 111 and leak-off pipe 124. If the pressure in the inlet chamber 15 should fall below a predetermined figure, e.g. 300 p.s.i., causing the member 24 to fall under gravity towards engagement with the flange 16, a first air operated valve (AVI), Fig. 2 (not shown), is actuated to allow fluid flow from the chamber 13 through the pipe 120 into the leak-off pipe 124, restoring the pressure differential. The valve (AVI) then closes, while a second valve (AV2) is actuated to allow fluid to flow into the chamber 12 through the pipe 120 and a further pipe 122 to restore the pressure balance. In an alternative arrangement, Figs 4-5 (not shown), the faceplates 22, 26 are retained on the members 16, 24 by hydrostatic clamp assemblies (136).
