Filed: 1927-10-15
Abstract: 303,227. Sonsthagen, A., and Poverud, G. M. Oct. 15, 1927. Disc and like mills; roller and roller-and-breast mills; mills and apparatus.-A mill for grinding coffee &c. comprises a grinding element having a plurality of effective surfaces so arranged that the material during its treatment is intermittently caused to follow a path inclined to the direction of motion of the surface or surfaces acted thereon, and whilst following the path is open to the atmosphere for the access of air and the escape of gases. In Fig. 1 a rotating or stationary stone 1 is provided with grinding surfaces 2 and clearing grooves 3 and in contact with the stone 1 is an open framework 4 made up of bars 5 which comprise the grinding elements. The open spaces between the bars allow of the escape of gases and the cooling of the material during grinding. The material is fed to the centre of the stones by a hopper 7, Fig. 4, and a wall 5a may be provided on the periphery of the rotating member 5 to prevent escape of the material. The bars 5 may be curved. When applied to a cylindrical member the bars are arranged to form a saddle or a series of saddles, Fig. 7, the inner surface of which is of a contour corresponding to that of the surface of the roller to which it is applied. The rear edge of the active surface of the bars 5 may be bevelled at x, Fig. 5. Multistage machines comprising rollers or discs may be employed, the material passing in cascade through the rollers or discs. The grinding surfaces may be given the form of a grid rotating about a fixed roller. One or more fans may be fixed to the rotary member to furnish a current of air to the grinding surfaces and hot or cold water coils may be fixed in the fixed or free members of the grinding surfaces. The bars or plates may act on the internal surface of a rotary roller or hollow cylinder. Blades or vanes may act on the material to cause it to travel longitudinally of the roller or cylinder at intermittently varying speeds.

Title: Means for testing low frequency systems
IPC: H03K3/04
Filed: 1947-10-14
Abstract: 650,819. Cathode-ray oscillographs. GUYOT, G. J. L., and GILLET, P. Oct. 14, 1947, No. 27572. Convention date, Sept. 28, 1946. [Class 37] Low frequency apparatus, e.g. audio-frequency amplifiers, is tested by injecting short pulses and studying the wave-form and/or phase displacement of the resultant output, the pulses being generated by a multivibrator and the time base from a separate multivibrator or from an electrode of the first multivibrator. As shown in Fig. 1, a multivibrator M1 produces short pulses which are taken from 11 for application to the low frequency channel ; a multivibrator M2 produces short time base pulses for the cathode-ray tube receiving the output pulses of the channel ; both multivibrators are synchronized by a low frequency oscillation from 12 applied over phase shifters 7, 8 and limiters 5, 6 so that the time base can be adjusted to cause any part of the output pulses to be revealed on the oscillograph. As shown in Fig. 2a, the multivibrator M provides at 11 the pulse for passage through the channel ; from grid 13 a voltage as shown in Fig. 3 is taken and applied to valves 16, 17 to produce a saw-tooth wave, Fig. 4, of the same periodicity as the pulses ; this saw-tooth wave form is applied to an amplifier 25, Fig. 2b, over a limiter 22 having a variable potentiometer 24 to limit the saw-tooth wave form, Fig. 4, as desired. The saw-tooth wave form of Fig. 4 may be limited at either or both the upper or lower portions to produce time bases as shown in Figs. 5, 6 and 7, the phase of that of Fig. 7 being adjustable according to the degree of limitation, so that a part only of the output pulse can be displayed over the whole of the screen. In another arrangement, a multivibrator M1, Fig. 8, produces at 11 the testing,pulses, and synchronizes a multivibrator M2 which produces square waves whose duration is varied by, potentiometer 28 ; the trailing edge of the pulses from S of M2, varied as desired by potentiometer 28 is used to initiate a saw-tooth time base ; the cathoderay beam is switched on by the pulses from M1 modified at 29 to be as shown in Figs. 12 and 13.

Title: Process and apparatus for grinding surfaces
IPC: B24B3/34
Filed: 1954-09-24
Abstract: 755,907. Grinding machines. AMRHEIN, H., [trading as WENDT KOMM.-GES., F.]. Sept. 24, 1954 [Sept. 24, 1953; Nov. 20, 1953; March 8, 1954], No. 27703/54. Class 60 A grinding or abrading tool 25, Fig. 1, and a workpiece 32 receive two relative reciprocations imparted simultaneously, the directions of the reciprocations being parallel to the surface to be ground but not parallel to each other. In the embodiment shown in Fig. 1 both reciprocations are imparted to the tool 25 and are produced by a motor 11 which drives an eccentric 18 through reduction gearing 12 at 140 r.p.m. and an eccentric 22 directly at 2800 r.p.m. The eccentric 18 is connected by a link 19 to a fixed pin 20 so that the motor 11 and hence the tool 25 are caused to reciprocate in a vertical direction, the motor being supported by springs 16a, 16b, while the eccentric 22 causes the tool 25 to reciprocate laterally between a pair of spring guiders 24 secured to the motor support 13. Either two or four springs may be used to support the motor 11 and the springs may have different constants in order to suppress any tendency the vertically reciprocating masses may have to rock. The workpiece 32 is carried by a table 34 which may be angularly adjusted and clamped about a pivot 39 in a position indicated by a pointer 41 and a scale 42 and adjusted vertically by a hand-operated rack and pinion gear 36. 37. A zero mark 44, Fig. 4, is provided alongside the tool 25 in a position corresponding to the centre of the latter at the central point of its reciprocation to facilitate adjustment of the workpiece 32. The tool 25 is held in a screw-operated clamp 26, 27 and is provided with an additional abrasive surface 31 which may be used by rendering the vertical reciprocation of the tool inoperative. A pump 46 operated by the movement of the motor 11 draws fluid from a trough 48 and feeds it through a pipe 52 to the tool. In a second embodiment, an eccentric 61 with which the motor support is held in contact by springs 69 produces the vertical reciprocation, the. eccentric being driven by gearing 67. 68 and a worm gear 65 from a motor shaft 64. The lateral reciprocation is produced by an eccentric 22<SP>1</SP> balanced by a mass 73 and acting on the tool 23<SP>1</SP> through a main .ball bearing 74 and four auxiliary bearings 75 which reduce the load on the main bearing. A hand-operated eccentric 70. Fig. 6. enables the motor to be lifted out of engagement with the eccentric 61 to stop the vertical reciprocation. Layers 77, 78 of vibration damping material, such as rubber, buna or resilient plastic material, are provided between the motor and its supports. A pump 15' is also provided. In this embodiment, the rack and pinion adjustment for the work table includes a worm drive.

Title: Improvements in or relating to the process for the preparation of unsaturated ester monomers
IPC: C07C69/54
Filed: 1950-11-14
Abstract: High molecular weight esters of acrylic or methacrylic acids having from 5 to 30 carbon atoms in the ester group derived from the alcohol are made by reacting at below 130 DEG  C. a low molecular weight ester of the said acids having less than 5 carbon atoms in the ester group derived from the alcohol and an alcohol having from 5 to 30 carbon atoms in the molecule in the presence of an acidic esterification catalyst and a polymerization inhibitor while passing a stream of an oxygen-containing gas through the reaction mixture, the products of the reaction being subjected successively to a stripping step and a washing step to recover the final product. Phenolic inhibitors, e.g. quinone, hydroquinone or tert.-butyl catechol, are preferred.  Generally an excess of the lower ester, e.g. methyl acrylate and methacrylate, is used reaction preferably being effected under reflux at about 90-120 DEG  C., whilst a stream of air and nitrogen containing 1 part of air to 5 to 20 parts of nitrogen is passed through during the reaction and stripping operations.  In the stripping stages lower molecular weight alcohol is removed together with excess lower ester.  When the bottoms temperature during atmospheric stripping reaches 110-120 DEG  C. vacuum stripping is effected until the temperature is again within these limits.  The product is washed with water to remove catalyst, alkali to remove inhibitor and finally with water.  In experiments mixed alcohols obtained by hydrogenating coconut oil, C8 oxo alcohols, or mixed hydrogenated coconut oil and C8 oxo alcohols are treated with methyl acrylate and methacrylate in the presence of p-toluene sulphonic acid and the three specified inhibitors whilst various mixtures of air and nitrogen or nitrogen alone are passed through and the products isolated as above.  In one case no inhibitor is used. Specification 573,175 is referred to.

Title: Nuclear reactor
IPC: G21C1/08
Filed: 1966-06-22
Abstract: 1,137,757. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 22 June, 1966, [28 Sept., 1965], No. 27832/66. Heading G6C. In a direct-cycle boiling water nuclear reactor, steam separation is effected by gravity and the power is adjusted in accordance with water level within the reactor. Pressurized water passes downwards through the core to emerge from the base of the core as a steam-water mixture. The water falls into a collection basin while the steam flows upwards through the peripheral superheater core sections, to the turbine supply ports in the pressure vessel. The pressurized feedwater inlet from the turbine condenser passes into the base of the pressure vessel through a jet pump mounted in the collection basin. Feedwater and unevaporated water from the core are urged upwards through a central pipe to the core upper surface. Changes in turbine power demand produce corresponding alterations in the level of the water in the collection basin which are detected by transducers to effect the required corrective movement of the control rods. In an alternative form, the jet pump is separate from the pressure vessel and supplies feed-water directly to the core upper surface. Each fuel element incorporates both evaporator and superheater sections and the coolant passes initially downwards through the inner evaporator section of each element and then upwards through the outer superheater section.
