Title: Improvements in or relating to indirectly-heated cathode structures
IPC: H01J9/04
Filed: 1965-08-03
Abstract: 1,110,455. Thermionic cathodes. SIEMENS A.G. 3 Aug., 1965 [4 Aug., 1964], No. 33061/65. Heading H1D. An indirectly-heated cathode comprises a conductive base carrying an emissive layer in the form of a semi-conducting paste, e.g. of alkaline earth compounds, containing metallic fibres, each fibre being sintered to the base and extending to the emissive surface so that it is substantially perpendicular to the base, and being formed by aligned metal particles sintered together. The cathode may be produced by application of a magnetic field perpendicular to its surface during the spraying on of nickel powder, or a mixture of nickel powder with alkaline earth carbonates, followed by sintering. If nickel powder only is applied, the nickel fibres may be formed by sintering prior to application of the alkaline earth carbonates. Alternatively, the cathode may be produced by placing a mixture of nickel powder and alkaline earth carbonates in a press-mould and applying a magnetic field perpendicular to its surface during a shake-up process and prior to sintering.

Abstract: 869,061. Rotary dashpots. ARMSTRONG PATENTS CO. Ltd. Sept. 5, 1957 [Oct. 31, 1956; Feb. 23, 1957], Nos. 33163/56 and 6155/57. Class 108(3). [Also in Group XXV] In a door closer having a shaft 4 (Fig. 1) rotatable by spring pressure and a. hydraulic check comprising a vane 15 (Fig. 3) secured to the shaft and disposed in a chamber which it divides into two compartments, a single movable valve member 33 is provided in a passage in the shaft which permits a free flow of fluid between the compartments when the door is opening but offers a predetermined resistance to flow during the closing movement. The valve member 33 has a conical surface and is urged by a spring towards a seat 4b in the hollow interior of the shaft which communicates with the compartments by means of two bores 17 (Fig. 3) situated at the levels 18 (Fig. 1) and passing through the vane and shaft. The vane chamber is formed by the door closer casing 5 and a diaphragm 14 and contains a stop 21 secured by a peg 22. When the door is opening fluid flows downwardly through the shaft and the valve yields, while during the closing movement fluid flows upwardly through the shaft and passes through the annular space between the valve member and its seat the width of which can be adjusted by means of a screw 20 which abuts an extension 33a of the valve member. To prevent cavitation behind the moving vane springless non-return valves are provided in the diaphragm 14 which permit fluid to flow through the diaphragm in the downward direction. In a modification a compression spring is fitted between the valve member 33 and the threaded part of the screw 20, so that any excessive upwardly directed nuid pressure through the shaft 4 will tend to close the valve and resist slamming of the door.

Filed: 1928-11-16
Abstract: 324,157. Bangert, H., and H³hn, G. Nov. 16, 1928. Gaseous-fuel furnaces.- In a burner for regenerative gasfired furnaces, the channels which convey separately the whole of the heated and the whole of the unheated gaseous constituents and other channels which convey a portion of the combustible mixture to the furnace and to the regenerator to be heated meet at one and the same point in the burner both before and after reversal of the regenerator. As shown in Fig. 5, the burner comprises channels 1, 2 leading to and from the regenerators, which may heat the air or gas, and a channel 3 leading to the furnace, unheated air or gas being supplied at 8 at the junction of the channels 1, 2 and 3. As indicated by the arrows part of the heated fuel constituent entering the burner through the channel 2 meets the other fuel constituent in the burner at a point from which part of the mixture passes through the channel 3 to the furnace and the remainder through the channel 1 to the regenerator. The passages entering the burner from the regenerators are disposed symmetrically to a plane containing the channel 8 supplying the unheated fuel constitutent and the channel 3 leading to the furnace. Other modifications are described wherein the furnace is provided with a number of burners as described above arranged adjacent to one another. Specifications 17956/13 and 28049/13 are referred to.

IPC: G07F5/22
Filed: 1962-09-03
Abstract: 1,001,090. Coin freed apparatus; electric calculators. A. KUCKENS. Sept. 3, 1962, No. 33691/62. Headings G4A and G4V. An electronic stepping register is used to record the value of goods demanded from a coin freed sales machine, a second such register is used to record the value of coins inserted into the machine, and a third such register is employed to record the coinage to be dispensed from the machine by way of change given or money returned. As shown in Fig. 2, bi-stable circuits 80 to 87 are connected as a stepping register II into which goods values are additively accumulated on a binary scale by way of injection over terminals 41 to 47. Inserted coin value is similarly accumulated over terminals 57 to 63 on both of the registers I and III comprised by bi-stable circuits 64 to 70 and 71 to 78, respectively. When faced with a demand for delivery of goods, control circuits 79 and 88 step register III and then register II, alternately, so that if register II is stepped to its final stage before register III the goods value is known to exceed the inserted coin value as originally recorded in register III. In these circumstances the goods are not delivered but the record of inserted coin value preserved in register I is transmitted over terminals 50 to 56 to cause the return of coin equivalent in value to those inserted into the machine. If, however, register III reaches its final stage before register II the goods are known to be covered by sufficient in coin value and delivery of the goods is sanctioned. In this event register I is cleared and is then stepped with register II until this is exhausted. By this means register II records the excess of inserted coin value over goods value and over terminals 50 to 56 governs the delivery of appropriate change coinage.

Title: Production of anhydrous polymer solutions
Inventor: WILLERSINN HERBERT
IPC: C08F279/02
Filed: 1965-08-06
Abstract: Polymer solutions having a water content of less than 0-1% by weight, are produced from systems containing a polymer and at least 5% water by dissolving the polymer in at least an equal amount of an organic liquid consisting exclusively or partly of an ethylenically unsaturated compound, adding to the resulting solution 0-05 to 20% of an inorganic sedimentation aid and removing the water and undissolved constituents by means of a separator at 5 DEG  to 50 DEG  C.  The water-containing polymer system may be a water-moist polymer or an aqueous polymer dispersion e.g. produced by emulsion or suspension polymerization.  The unsaturated liquid used may be mixed with a conventional solvent. The sedimentation aids specified are kaolin, ZnO, TiO2, Al2O3, BaSO4, whiting and Ca(OH)2 and/or silica gel.  When a polymer dispersion is treated, an electrolytic precipitant, e.g. dilute H2SO4, CaCl2, Al2(SO4)3 or NaCl may be added before or after the organic liquid.  Separating agents, e.g. polyethers such as polypropylene and polyethylene glycols may also be added.  In Example 1 a polybutadiene containing 32-5% H2O is dissolved in styrene, Al2O3 is added and the water is removed by centrifugation.  In Example 2 a mixture of styrene and ethylbenzene is used to dissolve a butadiene/styrene/di-n-butyl fumarate polymer containing 9.2% H2O, kaolin is added and the water is removed in a continuous separator. In Example 3 a solution comprising styrene, polypropylene glycol, aqueous NaCl and aqueous H2SO4 is added to a 10% aqueous polybutadiene dispersion, the bulk of the water is removed, kaolin is added and the remaining water removed in a continuous separator.

Title: Improvements in and relating to vibrators, more particularly for the vibration of concrete
IPC: B06B1/16
Filed: 1935-12-07
Abstract: 463,494. Vibratory mechanism. FAIRWEATHER, W. C. (Materiel Altex) Dec. 7, 1935, No. 33995. [Class 80 (iv)] A self - contained portable vibrator adapted to be attached to a receptacle for concrete or other materials to be consolidated, comprises a casing 5 in which is journalled a power driven shaft 1 carrying eccentric weights 8, 13, and having a handle 18, attachment lugs 24, and means for varying the angle between the weights during working. A collar 9, Fig. 1, having an undulatory groove 10 engages a pin 11 on a spring- pressed cap 12 integral with the weight 13. The handle is secured to a member having a boss 16 bearing on the cap 12. If the handle is pushed in the follower 11 climbs up an incline of the groove and then passes into the next trough with the result that the angle between the weights is varied, and, therefore, the amplitude of the vibrations. In a modified construction, the angle is varied by means of screw mechanism operated by an external hand wheel. In a further modification, in which the adjustment is automatic and depends on the power of the driving motor, a weight 31, Figs. 6 and 8, is keyed on the driving shaft 36 and a weight 32 is loosely mounted on a coaxial shaft 38. Links 34, 35 are journalled eccentrically in the weights and pivoted to one another at P, the pivot being connected to a pin 42 on the weight 31 by a spring. 33. The angular position of the pivot relative to the weight 31 may vary between limits imposed by the movement of a tail piece 43 of the link 34 between arms of the weight 31. The links 34, 35 constitute in effect a third weight, which is urged towards the axis by the spring, the radius of gyration of the combined weights being a minimum when the third weight is nearest the axis.

Filed: 1933-12-05
Abstract: 433,118. Weighing-apparatus; electric signalling systems. VALLE, J., 30, Clyde Road, Addiscombe, Surrey. Dec. 5, 1933, No. 34178. [Class 143] [See also Group XXXVIII] In a weighing-machine one of the moving parts (a sector-shaped member 4), is provided with a plurality of peripheral divisions (flexible members 5), spaced apart from one another and between any two of which, according to the weight to be indicated, a feeler member 6 may be interposed and is adapted after passage between two divisions, to operate one of a plurality of plungers 11 or the like (slidably mounted on the sector), effective to bring about the indication of the weight. Upon placing the commodity on the scale pan the sector 4 is correspondingly moved. Manual closure of a switch in the circuit of a motor 28 causes the feeler member to descend. A small roller on the feeler member passes between two of the flexible divisions 5 and an extension of the feeler member depresses the opposed plunger 11. The selected plunger depresses a corresponding arm 13, Fig. 3, to the horizontal position shown by dotted lines, where it is retained by a catch 16. The feeler member then rises clear of the sector and a camoperated rod 34 returns the sector to zero position. This movement of the sector brings the depressed arm 13 opposite an electric contact appropriate to the weight. The return of the sector 4 closes the circuit of a further motor which now pushes a contact slide against the end of the arm 13 to close an appropriate circuit for giving an indication of the weight of the commodity. During its return movement the slide liberates the arm 13 and stops the motor.
