[Class 52 (v).] A collapsable display card or stand comprises a background with a hinged step or shelf, each part being foldable upon itself and upon the other part so that the stand can be collapsed flat. In the construction shown in the Figure the background consists of a back 1 with two hinged side-wings 2 and a shelf 4, hinged at 5 to the back and at 6 to the wings. The shelf has a hinged riser 7 with a hinged foot 9. The shelf, riser and foot are scored along lines 18 so that when the riser and foot are brought into the same plane and the wings 2 closed inwards the central part of the shelf &c. will fold upwardly towards the back and the whole structure collapse flat thereon. A back may have a cut-out portion 11 with a hinged flap 12, an auxiliary 15 structure forming a background for the flap 12 being hinged to the rear face of the back 1. In a modification the background is divided transversely into three parts and the wings provided with cut-out hinged flaps to retain articles supported on the shelf 4 which may also have cut-out portions.

Title: Improvements in producing fast dyeings on mixed fabrics of wool and viscose artificial silk
IPC: C09B33/147
Filed: 1936-12-21
Abstract: Mixed fabrics of wool and viscose artificial silk are dyed by impregnating with water soluble salts of diamides derived from polynuclear o - hydroxy - aryl - carboxylic acids (2 mols.) capable of coupling, and arylenediamine sulphonic or carboxylic acids (1 mol.) to the fibres and subsequently developing with diazotized aromatic amines, the components being such that the dyestuffs, when prepared in substance, are difficultly soluble or insoluble in water. The diazo components are preferably free from carboxylic and sulphonic acid groups and aniline, nitranilines, chloranilines, aminodiphenylamines and aminoazo compounds are specified.  The impregnation may be carried out in neutral or in slightly acid baths. Diamides from naphthylenediamine mono- or disulphonic acids, phenylene-, chlorphenylene- or methyl-phenylene-diamine sulphonic acids, benzidine-, tolidine- or dianisidine-sulphonic acids, diaminostilbene disulphonic acids or 4.41 - diaminodiphenyl - 3.31 - dicarboxylic acid and 2 - hydroxynaphthalene - 3 - carboxylic acid or the o-hydroxycarboxylic derivatives, capable of coupling, of anthracene, phenanthrene, triphenylene, diphenylene oxide, carbazole and 1.2-benzocarbazole are specified.  Many examples of dyeings with various combinations of components are given.  Arylides of the type specified above are prepared by (1) causing polynuclear aromatic o-hydroxycarboxylic acid chlorides or o-acetoxycarboxylic acid chlorides to react in aqueous alkaline or pyridine solutions with arylenediamine sulphonic or carboxylic acids, the acetoxy groups, if present being thereafter split off, or (2) condensing the o-hydroxycarboxylic acids with arylenediamine sulphonic or carboxylic acids in organic solvents, e.g. benzene or toluene, in the presence of inorganic acid halides, e.g. phosphorus halides or thionyl chloride.

Title: Elimination of signal weakening in television transmitters
IPC: H04N5/38
Filed: 1937-12-24
Abstract: 506,189. Valve circuits. RADIOAKT.- GES. D. S. LOEWE. Dec. 24, 1937, No. 35708. Convention date, Dec. 24, 1936. [Class 40 (v)] To eliminate distortion in a television transmitter or amplifier due to anode supply varia - tion when the transmission is switched to and from synchronizing level the output is distorted before it is fed to the transmitting valve. As shown, the output of the modulation amplifier 19 is distorted by the amplifier M before it is fed to the transmitting valve 30. Two valves are used in M so that the incoming and outgoing signals are in phase although a single valve only could be used. The compensation is effected by condensers 23, 23<1> and resistances or inductances 22, 22<1> which lift the low tones, the components of the circuit being adjusted until the output, as shown on an oscillograph, is of the required shape. Rectified reaction through 27, 28 maintains the basic value of the control potential at the same level. The Specification as open to inspection under Sect. 91 also shows methods of compensation in which the anode supply is bridged by a buffer valve and in which a tetrode transmitting tube is used, the screen potential being maintained constant. This subject-matter does not appear in the Specification as accepted.

Abstract: 510,774. Controlling aircraft. KSOLL, J. Dec. 12, 1938, No. 36169. Convention date, Dec. 13, 1937. [Class 4] . In an aircraft wing having an adjustable aileron and a flap forming a normal profile with the wing; the flap being carried by the aileron and forming a gap with the lower surface of the aileron in its extreme adjusted position, the flap is arranged in the inoperative position above or behind the aileron and is oscillatable about the tracking edge of the aileron. The flap III, Fig. 1. is nested in a recess in the upper side of the aileron II and mounted on links 4, 5 supported on a plate 6 on the aileron. The aileron is pivoted on a bracket 9. An operating lever 2 pivoted at 1 is connected to the nose of the flap III by a link 3 and to the nose of the aileron II by a link 7. The aileron and flap are shown in the operative position in dotted lines. In a modification the aileron and flap are, in the inoperative position, contained in a slot 10, Fig. 4, in the wing and the aileron is pivoted at 16 to a U-section bar 12 running on rails 11 fixed to the wing and is connected by a link 17 to a bar 13 runnng on rails in the bar 12. The flap is operated by a rope 21 passing- over pulleys 22 mounted on the aileron, the end of the rope being fixed to the bar 13. A closing member IV, mounted on the bar 13, closes the gap 10 when the aileron and flap have been shifted rearwardly. A spring tends to move the bar 13 rearwardly relative to the bar 12 and the bar 13 is adapted to' engage stops on the rails 11 at the stage indicated by dotted lines, whereupon the bar 12 moves further and the aileron and flap are moved to the position shown in full lines. The operating .mechanism comprises a pinion 20 acting on a rack formed on the bar 12. A spring 43 retains the flap in the recess in the aileron. In the modification shown in Fig. 9 the aileron and flap are normally arranged in a recess beneath the wing, both_the bar 12 and bar 13 have racks and are operated by pinions 20, 20<1> connected by gearing. The rack 10<1> on the bar 13 is shorter however, in order that the bar 12 should be moved before the bar 13 has started and after the bar 13 has stopped. The flap III is pivoted at 23 on the aileron and is operated by a toggle 26, link 32 and bell-crank 29 which has a slotted arm 31 adapted to be engaged and operated by a fixed pin 33 in the initial movements of the aileron. The pin moves the bell-crank past a dead centre in which it remains for the latter part of the aileron movement. In a further modification the main adjusting surface II, Fig. 13, is pivoted at 34 and operated by a lever 37 and link 36 and the flap III is operated by a link 39, a lever 40, sprockets 38, 41 and a crossed chain 42. In a similar construction the wing is constructed with a gap between the parts I and II.
