Title: Source of radioactive radiation and a method of producing the same
IPC: G21G4/06
Filed: 1958-05-23
Abstract: 865,773. Radioactive sources. DEUTSCHE EDELSTAHLWERKE A.G. May 23, 1958 [May 25, 1957], No. 16736/58. Class 39(4). [Also in Group XXXV] A source of radioactive radiation is in the form of a permanent magnet or permanent magnet system. In use the source may thus be temporarily attached to a ferromagnetic object. The radioactive material may be a constituent of the magnet, e.g. cobalt-60 associated with nickel and aluminium, or may be contained in a recess in the magnet. A mixture of powdered radioactive material and powdered ferromagnetic material may be compressed, sintered, and magnetised; alternatively the mixtures may be compressed with an organic binding agent. Other methods involve adding the radioactive material during the casting of the magnetic alloy or soaking porous magnetic material with the radioactive material in liquid form. As shown, the magnet 1 containing radioactive material 2 in a recess 4 is inserted in a ferromagnetic pot 6 with the interposition of a sleeve 5 of non-magnetic radiation absorbing material, e.g. lead, zirconium, or titanium, and the whole enclosed in a shield 3 of similar material. A statement of prior art refers to mixtures of carbon with ceramics or with metals as carriers for radioactive material and also to enclosing the radioactive material in a ferromagnetic capsule which is held in position by an electromagnet.

Filed: 1969-03-31
Abstract: 1,235,393. Rotary positive - displacement pumps and motors. GERMANE CORP. March 31, 1969 [Dec.31, 1968], No. 16836/69. Heading F1F. A reversible pump, or motor, has a star member 30 rotatable in a planetary manner while meshing with a fixed ring-member 29 and coupled to a power input, or output, shaft 43 by a splined member 54 abutting rings 60, 61, flow of working fluid e.g. oil or air, between inlet and outlet ports 23, 24 and cells 34a to 34g being controlled by a rotary valve-member 36 connected to said shaft by a shear pin 51 engaging with a slot 53. Shifting the pin so as to engage with either a slot 52a or a slot 52b, according to the desired direction of rotation of the star member, reduces cavitation or trapping of working fluid in some of the cells that is caused by any lack of synchronism between the star member and the valve member due to wear, torsion and backlash. Additional slots for the pin may be included in the valve member and the angular spacing of the slots may differ from that shown. The valve member has annular grooves 38, 39 in register with the ports 23, 24 and intersecting alternate slots 40, 41, respectively, which slots during rotation of the valve member periodically and sequentially communicate with the cells through corresponding openings 26 and passages 25. The valve member is supported by the wall of a bore 17 and is separated from the shaft by an annular gap, the shaft being supported by bearings 45, 46 situated between thrust bearings 49, 50.

Title: Improvements relating to the fine adjustment of ignition timing on internal combustion engines
IPC: F02P5/02
Filed: 1950-07-06
Abstract: 675,248. Rotary distributers. DAIMLERBENZ AKT.-GES. July 6, 1950. [July 6, 1949] No. 16966/50. Class 38 (v). [Also in Group XXVII] In an arrangement for the fine-adjustment of the ignition timing of internal-combustion engines in which the ignition distributor housing is turned by means of an adjusting member 4, Fig. 1, connected to it, there is provided a two-armed, fine-adjustment lever which actuates the member 4 with a given movement ratio, the longer arm 6 serving for manipulation purposes whilst the shorter arm 7 turns the member 4. A base plate 1, secured to the engine cylinder head by a screw 2 has the distributor throat 3 passing therethrough, whilst the member 4 is clamped to the throat part 3 by a screw 5. The lever is pivotally mounted on the base plate 1 so that to adjust the ignition timing the longer arm 6 is moved to a given position on a scale 9 on the base plate, the shorter arm 7, which engages in a slot 10 in the member 4, thereby moving the latter a relatively small distance. In a modification, the adjusting member 16, Fig. 3, is extended so that the adjusting-lever pivot also passes through an elongated hole 19 therein, the short arm of the lever being formed as an eccentric 20, whilst the longer arm 21 has a depending part which can drop into any of the division marks on the scale 23. The lever is spring-loaded so that it merely requires lifting against the spring before moving it over the scale thereby obviating the necessity for using any tools during adjustment of the ignition ; the spring also prevents unintentional alteration of a given ignition setting. The base plate may be dispensed with and the hand lever pivot mounted directly on the engine cylinder head.

Filed: 1917-11-17
Abstract: 129,663. Tuckfield, C. Nov. 17, 1917. Drawings to Specification. Regulating.-In aircraft engines, compression is maintained constant at all altitudes by rejecting portions of the charges during the compression strokes. The inlet valves are actuated by cams controlled by barometric devices, and are held open during variable portions of the compression strokes. The rejected charges may enter an inlet pipe which is provided with cowls to deflect the charges in the direction of the cylinder in which suction is occurring. The delivery passage from the carburettor has a hood which faces in the same direction as those on the inlet pipe. A check valve may be fitted to the inlet pipe between the cylinder and the carburettor to prevent loss of rejected charges. According to the Provisional Specification, the cams may be manually controlled through Bowden-wire mechanism.

Title: ª‰-(2,5-dimethoxyphenyl)-ª‰-hydroxyisopropylamine
Filed: 1942-11-30
Abstract: b -(2 : 5 -dimethoxyphenyl)-b -hydroxyisopropylamine is prepared by a two-stage reduction of 2 : 5-dimethoxy-a -isonitrosopropiophenone using a palladized charcoal catalyst for the first stage and a platinum catalyst for the second stage.  The first stage in the reduction results in the formation of the ketoisopropylamine.  In an example, 2 : 5-dimethoxypropiophenone is treated in ether solution with methyl nitrite and hydrogen chloride to form 2 : 5-dimethoxy-a -isonitrosopropiophenone.  This is dissolved in absolute alcohol containing hydrogen chloride and hydrogenated in the presence of palladized charcoal to form b -(2 : 5-dimethoxyphenyl)-b -ketoisopropylamine hydrochloride, which on further hydrogenation in aqueous solution in presence of platinum oxide gives the required b -(2 : 5-dimethoxyphenyl) - b -hydroxyisopro - pylamine.  Acetylation with acetic anhydride gives the diacetyl derivative.  The compounds of the present invention act as a powerful, long acting pressor and mydriatic.

Abstract: 186,155. Pressland, C. June 21, 1921. External spark-gaps.-An external spark-gap is formed within a vitreous housing 1 between the ends of the central electrode 4 and high-tension conductor 3. Cooling is promoted by passages 10 which put the tapering passage 2 in communication with the atmosphere. Retention of the hood is ensured by a spring detent 7. The high-tension conductor is bared for a length equal to the narrow part 9 of the passage in the hood, and the insulation is then screwed into the threaded portion 8 so as to leave the necessary gap. In a modification, Fig. 3, the gap is formed between the copper bush 16 and the thimble 19, a vitreous hood 15 and a bush 12 acting as insulation. The thimble 19 may be an integral continuation of the high-tension conductor, or an additional hood 18 may be fitted having a passage 22. The conductor 24 passes into the reduced end of the passage; its bared end is secured in a block 21, which is pressed forwards by a spring 26 so that the end 20 engages the thimble 19. By withdrawing the conductor 24, the hood 18 may be lifted off.

Title: Improvements in or relating to electric motor control systems
IPC: B60L7/04
Filed: 1953-06-23
Abstract: 724,867. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 23, 1953 [July 26, 1952], No. 17340/53. Class 38 (3). Dynamic braking operation of a traction motor is provided by connecting a fixed resistor Rb across the armature of the motor and exciting the field winding MF from a variable voltage generator G. An over-voltage relay 6' is connected across the motor armature through an adjustable resistor R1 and is adapted to close contacts 6" for energizing a protective or indicating circuit when the braking- current exceeds a permissible value. A second protective relay 7, which is responsive to both motor speed and current, over-rides the relay 6 at high speeds, so that the protective circuit is rendered effective at lower values of the braking- current when the motor is working under unfavourable conditions of commutation. The relay 7 has an actuating coil 13 energized in accordance with the motor armature current, and an opposing coil 16 which is excited in response to the motor field current. In addition, a second opposing means, providing a strong, substantially constant biasing-force, consists of a tension-spring 17, this biasing-force being intermediate in value between the maximum and minimum values of the opposing force exerted by the coil 16. An advantageous response characteristic of the relay 7 is afforded by making the magnetic circuit 15 for the opposing coil become saturated before the magnetic circuit 12 for the operating coil, within the range of motor armature and field currents in which the differential relay is actuated, but the overvoltage relay 6 is not simultaneously actuated.
