Abstract: 170,168. Dietrich, J. G. Aug. 21, 1920. Dolls; stands.-A toy for imitating acrobats consists of a doll having flat and U-shaped limb extremities, which engage a bar of U-shaped cross-section. The bar 1, Fig. 4, can be supported by tubular posts 5, the bar being inserted in apertures 4 in the posts.

Title: Improvements in the flameless reaction of gaseous hydrocarbons
IPC: C01B3/38
Filed: 1956-08-09
Abstract: <PICT:0793504/III/1> In the production of synthesis gas by the catalytic interaction of a hydrocarbon and oxygen, optionally together with steam, admixing the gases to be reacted, passing the mixture of gases upwards through an enlarged space so as to reduce the speed of flow, then through a layer of non-finely divided non-catalytic refractory material in a fixed bed and finally through a layer of catalyst material in finely divided form which is thereby maintained in the fluidized state.  Apart from the fluidized step, operation is as described in the parent Specification.  As shown, coke oven gas, having a methane content of 30 per cent and steam from pipes 1 and 5 respectively pass through preheater 3 to mixer 7 where they are mixed with oxygen and steam from pipes 2 and 6 respectively and preheater 4.  The gaseous mixture at a temperature of 600 DEG  C. passes through conical expansion chamber 7a, layer 10 of sillimanite balls 15 cm. thick, supported on a grate 9 of ceramic material, and then through a layer 8 of a fluidized catalyst of magnesite impregnated with nickel oxide 60 cm. thick, whereby a reaction temperature of about 950 DEG  C. is produced.  Solid particles entrained in the gas leaving the fluidized layer are returned to the layer by means of centrifugal separator 11.  The velocity of the gaseous mixture is reduced to about one thirtieth of its former value on passage through the conical chamber.

Title: Differential amplified circuit
IPC: G06V30/10
Filed: 1969-05-14
Abstract: 1,262,001. Differential amplification. INTERNATIONAL BUSINESS MACHINES CORP. 14 May, 1969 [24 May, 1968], No. 24467/69. Heading G4G. In the differential amplifier 16, resistance R 3  is made unequal to resistance R 4  such that the output of the amplifier is the difference between multiples of the inputs. In the optical character reading device shown, the inputs to the amplifier 16 are the peak black and white levels detected by scanning device 10. The device is used to scan an initial character (e.g. the first letter of a line of print) in order to establish a clipping level at which the reading device operates after the initial scan (e.g. during the rest of the line). The clipping level is established by storing the output of amplifier 16 in a store 30 and adding to it in adder 32 a voltage representing the peak white level. The inequality of the resistances R 3 , R 4  ensure that the clipping level varies with the density of the characters.

Abstract: 469,916. Sound recording. ELLIS, L. S. E. (Klangfilm Ges.) Sept. 9, 1936, No. 24628. [Class 40 (ii)] [Also in Group XXXIX] Sound is recorded on a carrier 1 by moving said carrier in the direction of arrow a, Fig. 1, while a rod 3 of rapidly drying coloured matter is discharged thereon by a nozzle 2, and a recording member 4 is vibrated in synchronism with the sound to spread the rod into undulations of variable width or variable thickness or both. The coloured mass may be supplied by a pump, and the drying may be effected by drying devices. The recording device may be enclosed in a casing 8a, 8b, Fig. 2, which is made air-tight when the recording device is out of action and is supplied with the vapours of a solvent 11 for the coloured mass by a wick 12 to prevent the drying of the mass at the nozzle. The recording member 4 may be disposed straight across the carrier as shown in Fig. 1 and oscillated at right-angles to the surface of the carrier to produce a record of variable thickness ; or the member may be inclined laterally and disposed obliquely to the length of the carrier as shown in Fig. 3 to produce a variable width record ; or the member may be mounted on a rocking spindle to produce two record tracks in push-pull. The recording member may be constituted by a thin armature 14, Fig. 5, fastened with a plate 16 to a soft iron body 18 carrying a polepiece 19 surrounded by a coil 20. This electromagnetic device is carried by a lever 22 pivoted at 23 and counterbalanced by a spring or an adjustable weight 24. The armature 14 inclined towards the carrier 1, and the part of the coloured mass 3 collecting under the armature damps the oscillations. In a modification, Fig. 7, the coloured mass 3 is fed between the armature 14 and an adjustable plate 25, and this damps the armature.
