Title: Improvements in and relating to the manufacture of cellulose ethers
IPC: C08B11/00
Filed: 1923-07-09
Abstract: In the manufacture of cellulose ethers the amount of caustic alkali exceeds the amount of cellulosic material taken, and the quantity of water ties between <FORM:0200815/2/1> and <FORM:0200815/2/2> , in these expressions a being the amount of caustic alkali employed to each part of cellulose taken.  The initial material may be cellulose, or a conversion product or derivative in which the cellulose has not been degraded too far, or an ether of a lower stage of etherification.  The etherification may be carried out in one or several stages, and in the presence of diluents such as benzol, and with the aid of catalysts such as copper, copper salts, ferrous sulphate or other iron salt.  If a water-resistant ether is desired, the quantity of alkali should be 1.5 to 2.5 times the amount of cellulosic material taken.  Specifications 163,017 and 163,018 are referred to.

Title: Improvements in or relating to the transmission and reception of simultaneous multiple telemeasurements
IPC: G01D5/39
Filed: 1935-06-22
Abstract: 463,330. Electric signalling systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. June 22, 1935, No. 18006. Void. Convention date, June 23, 1934. [Class 40 (i)] [Also in Group XL] In a system for transmitting simultaneously a plurality of meter readings the meters control shutters A, W, V disposed in a beam of light L and arranged to obscure more or less light as shown in Fig. 2 according to the meter readings. A disc D having radial slits F rotates in the beam, the slits F facilitating the illumination of a photo-electric cell C by successive light impulses, the values of which are determined by the shutter positions. The electric impulses produced by the cell, which may modulate a carrier wave, are applied at the receiver to a cathode-ray tube to produce one co-ordinate movement of the ray, the other co-ordinate movement being produced by the signal related to the distance between the slits F. In this manner, the ray produces on a screen a trace having points t which with an associated scale provide indications corresponding to the measured valves. A synchronizing signal also is produced by the light impulse at E, Fig. 2. If at the receiver the synchronizing signal is received at a spot other than R, the ray affects one or other of the cells C<1>, C<2> to effect correction. Alternatively correction may be effected manually.

Pile supports.-The components are stored in two piles 46, Fig. 5, each supported on a circular feed blade 124 and against a pivoted end support 68, Figs. 3 and 5, and passing through an opening 45 in a laterally inclined plate 38, Figs. 3, 4 and 5. Above the plate 38 is supported one of a number of interchangeable plates 52 having a similar opening round which are secured a plurality of vertical pins 50 to define the periphery of the components, or by an equivalent sheet metal frame, each plate 52 accommodating a particular size of component. The pile is pressed downwards by a weight 55 on a constant-force spring. A pressure blade 103 enters the pile a few components above the bottom during separation and is cam-actuated to first press downwards and then reduce the pile pressure. The two plates 38 are connected by a V-plate 39. Separating sheets.-The blade 124 is helical with a raised leading point 126 which enters the pile above the bottom component, so that after one revolution of the blade the bottom component is transferred from above to below the blade by a screw action. Faulty feed or sheet detectors.-A pair of components separated from the two piles fall on to and down base-plates 151, 152 of a shoot 145 and are arrested by rods 158. Two photoelectric devices 160 each having a turret colour filter selector 162 compare the colour of the two components, and a further detector 156 enables a light comparison to detect the absence of one or both components. The rods 158 are retracted after the comparing operation.  Registering sheets.-The components fall after retraction of the rods into two compartments of a gauge 165 inclined rearwardly and closed at the bottom and rear, so that the two components are aligned with each other. Forwarding sheets.-After alignment, the gauge 165, Fig. 7, is rotated through 90 degrees by a pneumatic piston 213. In the event of rejection, a piston 231 rotates the gauge through 20 degrees, whereafter the components pass to a reject bin. After the 90 degree rotation, pins 264, Fig. 8, are lowered by a pneumatic cylinder 271 and pass through slots 182, 183, Fig. 4, in the gauge plates 175, 177 and through the components, and are then moved horizontally by a motor 240 to extract the components from the gauge and move them to a position where they are fed to the sewing machine by a plate 280.
