Title: Improvements in radiological apparatus
IPC: G03B42/02
Filed: 1964-05-11
Abstract: 1,060,751. Radiological apparatus. COMPAGNIE GENERALE DE RADIOLOGIE. May 11, 1964 [May 13, 1963], No. 19585/64. Heading H5B. In radiographic apparatus especially suitable for examination of, for example, the cranium, the X-ray arm 1 comprises a major portion 100 and a side portion 101, which enable the X-ray tube to be rotated along an arcuate path A, A<SP>1</SP> about an axis (X, X<SP>1</SP>) (Fig. 1, not shown), or to move parallel to itself (Fig. 3, not shown). The portions 100, 101 form the sides OM, PQ of a parallelogram OMPQ, the other sides MP, QO being formed at the tube and at a disc 6. The parallelogram can be fixed as a rectangle by locking the tube in position at the end of the arm 1, using a lever 4. Then, only rotation of the arm about the axis (X, X<SP>1</SP>) is permitted, the object to be examined being located at a point on this axis. When the lever is released, the disc 6 is locked to a fixed support arm (3) by means of a finger engaging one of the holes 7 in the disc. This allows rotation of the portion 100 about (X, X<SP>1</SP>) and of the portion 101 which is pivoted to the disc but prevents the arm as a whole from rotating about (X, X<SP>1</SP>). Instead, a deformation of the parallelogram occurs and the tube is allowed to move parallel to itself. The arm 1 is mounted on a column (not shown), together with the fixed arm (3), the arms being slidable along the column to provide for vertical displacement of the X-ray tube. The tube 2 may be swivelled on an axis (Y, Y<SP>1</SP>) at the end of its arm and locked in any position by means of the lever 4. A scale 8 is provided for lining up the central ray from the tube with the point to be investigated.

Patent GB-713824-A (GB)
Title: Improvements in or relating to cellulose nitration
IPC: C08B5/02
Filed: 1952-08-05
Abstract: A uniformly nitrated nitrocellulose is obtained by partially nitrating cellulosic material with a nitrating mixture comprising nitric acid and water at a temperature at which substantially no dissolution or swelling of the cellulosic material is effected, and then contacting the partially nitrated material with a nitrating mixture comprising nitric acid and water at a temperature higher than that of the first treatment and effecting a substantial further nitration of the material.  The first nitrating step may be conducted at a temperature between -50 DEG  C. and + 10 DEG  C., and for this step the nitrating mixture may contain 89-95 per cent. of nitric acid by weight, and the time of treatment may be 5-60 minutes.  To prevent partial dissolution of the nitrocellulose in the second step, the first treatment is continued until the nitrogen content of the material is at least 9 per cent.  The further nitration may be carried out at 10-45 DEG  C. using a nitrating mixture containing 90-99 per cent. by weight of nitric acid, the time of treatment being 10-60 minutes.  The cellulose used may be derived from cotton, wood or straw and it may be treated in bulk or shredded form.  It is preferably used in a dense physical form, e.g. in a dense sheet form. A sheet of the material may be taken from a roll and passed through the first nitration bath at a speed which allows the reaction to proceed to the required extent.  The sheet of partially nitrated cellulose may then be passed directly, or after passage through squeeze rolls, into the second nitration bath.  Concentrated nitric acid may be introduced into the second nitration bath, where it becomes diluted by water liberated during the nitration.  After passing through the bath, the acid may be passed through a refrigerator and then into the first nitration bath.  Acid from the first nitration bath may be re-concentrated and passed to the second nitration bath.  The treatment may also be carried out by passing the cellulosic material through a tube provided with a screw conveyer, and passing concentrated nitric acid through the tube in the opposite direction.  The tube is provided with heating and cooling devices in order that the two stages of the treatment may be carried out at the required temperatures.

Abstract: 992,267. Track circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 25, 1963 [May 24, 1962], No. 20058/62. Heading B7N. A railway track circuit comprises an insulated section of track TS, a D.C. source DCS connected via a modulating circuit M to one end of the section and a relay R connected to its opposite end. The output of the modulator comprises a voltage VS, Fig. 1A, varying cyclically between upper and lower levels and of a magnitude such that with no train present in the section and maximum inherent attenuation between the ends of the section, the voltage VR at the relay varies between an upper level which exceeds the energizing voltage VE of the relay and a lower level which falls between the voltage VE and the relay maintaining voltage VD. Under conditions where the presence of a train shunt does not reduce the upper level of voltage VR below the relay maintaining voltage the relay releases during the low level period. This period is chosen to be long compared with the relay release time. In a second arrangement, Figs. 2 and 2a (not shown), the modulating circuit is supplied from an A.C. source and a filter tuned to the source frequency is included in the connection to the relay.

Title: Improvements in or relating to the production of methacrylamide, methacrylic acid and derivatives thereof
IPC: C07C51/08
Filed: 1934-07-09
Abstract: Methacrylamide, methacrylic acid and salts thereof are manufactured by heating acetone cyanhydrin with at least one molecular proportion of sulphuric acid, e.g. to a temperature not exceeding about 130 DEG C., if desired in the presence of an antipolymerizing agent, e.g. copper, sulphur, tannic acid or resorcinol, and working up the reaction mixture so as to isolate the methacrylamide therefrom or to convert it into methacrylic acid or a metal salt thereof.  In order to isolate methacrylamide, the reaction mixture may be cooled, or it may be dissolved in water, the sulphuric acid removed by neutralization with a hydroxide or carbonate of an alkaline-earth metal and the solution filtered and evaporated.  Methacrylic acid is obtained by heating the reaction mixture with water, e.g. 2-6, preferably 3-5 molecular proportions to one of methacrylamide, and salts of methacrylic acid are produced by removing the sulphuric acid as an insoluble sulphate and then boiling with alkaline or alkaline-earth hydroxides.  Polymerized methacrylamide may be used as a softening agent or adhesive.  In examples: (1) acetone cyanhydrin is heated with sulphuric acid in the presence of sulphur and the product is dissolved in water, filtered, neutralized with calcium carbonate, again filtered and then evaporated to dryness, yielding methacrylamide; (2) crude acetone cyanhydrin is heated with oleum and sulphur, and the product boiled with water containing tannic acid and then poured into brine, whereupon methacrylic acid separates; (3) acetone cyanhydrin is heated with sulphuric acid and copper and the product is heated with water and then cooled to separate methacrylic acid.  Specifications 405,699 and 427,810 are referred to.

Abstract: 370,282. Coke ovens. OTTO & CO. GES. DR. C., 9, Christstrasse, Bochum, Germany. July 14, 1931, No. 20226. Convention date, July 14, 1930. [Class 55 (i).] Distillates are withdrawn from the centre of the charge in coke ovens for between the first two-thirds to three-quarters of the carbonizing period, after which steam is introduced into the charge through the gas withdrawal means. The steam cools the gas outlet tubes and generates water gas which increases the yield of gas in the second period. At the beginning of the carbonizing period steam, which may be mixed with water gas and coal gas, is introduced into the upper gas collecting space, and acts as a scavenging gas, these gases being introduced through the hydraulic main leading from the upper gas space. A vacuum up to 200 m.m. may be used in the central gas withdrawal tubes and varied automatically, to ensure that the pressure in the gas space is never higher than that in the heating flues. Cooling bodies may be inserted into the suction tubes. The distillates are withdrawn through ducts c, which are formed in the charge by introducing boring rods h movable in sleeves h<1> by grippers x fastened to chains x<1> the whole being mounted on a wagon w. Tubes k are inserted for drawing off the distillates through opening n leading by a pipe p and valve q to a hydraulic main v. Steam is supplied from a main t on closure of valve q, which normally is controlled automatically by means dependent upon the pressure difference between the gas space u and an adjacent heating flue. The gas spaces u of each oven are connected by a conduit s which serves also for introduction of steam during the last part of the carbonizing period, or of steam and coal gas at the beginning of the carbonizing period. The distillates in the last part of the carbonizing period pass through the conduit s and the chambers which are at the beginning of the period into the main v. Cooling elements m are placed in the tubes k and are cooled by water which is supplied drop by drop.

Title: Improvements in electric circuit controllers
IPC: H01H50/74
Filed: 1922-07-26
Abstract: 185,722. Arter, R. C. Sept. 8, 1921, [Convention date]. Electromagnetic switches.-Relates to a vibrating circuit interrupter to be used, for example, in a signalling device wherein a telephone bell is rung at definite intervals. As shown, the interrupter winding 3 receives current to attract the armature 4 and set it in vibration, since the slow-acting solenoids 12, 13 are de-energized. But this vibration, by completing circuit at 7, 9 and 7, 8, energizes these solenoids to break the circuit of the winding 3 and complete the signalling circuit 14. As the vibrations die down, the fixed contact 8 being the farther from the moving contact 7, the solenoid 13 is first de-energized, so that the signalling circuit is broken before both solenoids 12, 13, by releasing their back armatures, restore the original conditions. The contacts 8, 9 are adjustable by means of screws 10. and the core 2 has a non-magnetic sleeve 6 to prevent sticking. A copper ring or sleeve on the core of the solenoids 12, 13 renders them slowacting.
