Abstract: 281,717. Soc. of Chemical Industry in Basle. Dec. 4, 1926, [Convention date]. Urea-formaldehyde condensation products. - Artificial materials having a porous structure are prepared by first condensing urea and aqueous formaldehyde to a stage beyond the methylolurea phase, then adding an acid or non-basic salt in quantity sufficient to cause the whole mass to gelatinize with retention of the solvent, and finally removing the catalyst from the hardened product. The cataylst may be separated by washing-after neutralization in the case of an acid-or by electro-osmosis. The water present may be replaced by acohol or other solvent. Softening and filling agents or colouring materials may be added, either during the condensation or to the finished product according to the nature of the addition: as softening agents, triaryl phosphate, diethyl phthalate. linseed oil or latex are mentioned, and, as filling materials, cellular bodies, asbestos, or kieselguhr. A reagent which takes part in the resin formation, e.g. a phenol, amine or urea. may also be added. Subjection to high pressure, with or without application of heat, renders the products denser and stronger. According to the examples, (1) a neutral aqueous solution of formaldehyde is heated with urea, and sulphuric acid or ammonium sulphocyanide is added to the cooled' solution, which is then poured into a mould: the hard product is freed from the catalyst by immersion in caustic soda followed by washing; (2) a solution of urea in aqueous formaldehyde is mixed with blood charcoal, filtered and heated ; after adding an aqueous solution of aniline hydrochloride and urea, the mixture is poured into a mould, where it hardens; the product is freed from the catalyst by treatment with caustic soda and washing: a neutral aqueous paste of asbestos may be added to the condensation solution. Specification 261.409 is referred to.

Title: Improvements in and relating to systems of electric motor control
IPC: H02P5/74
Filed: 1922-12-07
Abstract: 210,236. British Thomson-Houston Co., Ltd., and Given, R. D. Dec. 7, 1922. Speed maintaining systems. - In systems for maintaining constant relative speeds of a number of electric motors, such as are employed for driving paper making machinery, each motor is provided with a device whereby the speed ratio between any pair of motors can be changed when required, without disturbing the speed ratios between other motors of the set. The figures show a system of alternating current motors 1, 2, 3, Fig. 1, controlled for constant relative speeds by brush shifting gear in the manner described in Specification 205,215. In order to change the speed ratio when required, each motor except the master motor 1, drives a pair of oppositely rotating sprocket wheels 16, 17, Fig. 3, which can be shifted along a shaft 14 by solenoids 22, 23 so as to clutch the brush shifting gear to either sprockat as required. The solenoids of all the motors are disposed in two groups as shown in Fig. 4, the circuit connections being such that the movement of a switch 33 puts in all the solenoids on the right hand side of the affected unit, and thus imparts a proportionate change of speed to each of the corresponding motors, their interrelation being thus undisturbed. Specification 210,229 also is referred to.

Abstract: 391,066. Glass manufacture. NAAMLOOZE VENNOOTSCHAP HOLLANDSCHE MAATSCHAPPIJ VOOR DE VERVAARDIGING VAN GLAS, 104, Weteringschans, Amsterdam. Nov. 26, 1932, No. 33512. Convention date, Nov. 26, 1931. [Class 56.] Relates to the method of making sheet glass in which a sheet a is drawn vertically upwards from a mass of molten glass, a slotted refractory block d<1> being immersed below the line of generation of the sheet. The edges of the sheet are drawn through slotted bowls f or similar edge-retaining members, in order to prevent the sheet from narrowing. According to the invention, screening members k, consisting of bricks or metal plates, are placed on each of the slotted bowls f, close to the edges of the sheet, in order to prevent the formation of thickened or warped edges. Each screen k preferably consists of a single refractory brick or a number of superposed bricks, but it may consist of a metal plate fitted with a lever or rod to enable it to be manipulated from the exterior of the apparatus. The screens deflect descending air currents away from the molten glass in the neighbourhood of the bowls f, and also prevent loss of heat from the glass by radiation. The position of the screens is adjusted as required to correct any malformation of the edges of the sheet.

Abstract: 666,886. Photo-electric colorimeters. ROUY A. L. M. A. Dec. 31, 1948, No. 33601/48. Class 40 (iii). In a photo-electric colorimeter, use is made of the whole scale of the instrument by mounting the photo-cell so as to rotate to bring the pointer to full scale deflection with the minimum sample density. As shown, light from a source 1 passes through one of a number of filters 3, 4, 5 mounted in a rotatable holder 2, through the sample in a container 6 and on to a photo-cell 10. This photo-cell is mounted on a pivot 9 and may be turned from the outside of the casing by a knob 16 which acts through worm gearing 11, 12. The axis of the pivot lies in the plane of the sensitive surface and the centre of the photo-cell lies on the axis of the light. In a modification, Fig. 2, the centre of the cell remains aligned with the axis of the light beam but the pivot is shifted. The photo-cell is mounted in a holder 23 and is moved to one side, the distance being indicated on the scale 30. The block 24 carrying the pivot is then brought back an equal distance relative to scale 28. Normally the axis of the pivot will be required to coincide with the edge of the cell. The cell may be pivoted horizontally. The Specification states that the total current output of the cell follows a cosine law with the angular rotation whether a converging, parallel or diverging beam is used.

Title: Type carrier for printing machine
IPC: B41J1/32
Filed: 1963-08-28
Abstract: 991,740. Selective printing. SPERRY RAND CORPORATION. Aug. 28, 1963 [Sept. 10, 1962], No. 33993/63. Heading B6F. Type-wheel machines; type-wheel actions.- A high - speed printing apparatus of the type in which a plurality of hammers 12, Fig. 7, ranged along a firing line are actuable individually or simultaneously to urge a line-by-line movable printing medium 13, Fig. 1, against type faces 51 on a continuously rotatable type carrier 10 having its axis of rotation parallel to the firing line is characterized in that the axis of rotation is adjustable from the position suited for parallel read-out in which the axis is parallel to the firing line to a position suited for serial read-out in which the axis is so oriented with respect to the firing line as to provide a delay in the positioning of successive types in a row opposite the corresponding hammer. The term parallel read-out denotes the mode of operation wherein the control information is made available for all print columns simultaneously and the term serial read-out the mode of operation wherein the control information is made available to the respective print columns serially and consequently no two print hammers will be actuated at the same time. The type carrier 10 is mounted on a shaft 11 which is rotatably mounted in self-aligning bearings 31, 41, supported in caps 32, 42, respectively, the caps being slidably received by castings 36, 46. The shaft 11 can be adjusted in a plane perpendicular or parallel to a firing plane, defined by the plurality of aligned hammers, by set-screws 37, 47 and 38, 48 to orientate the type carrier axis for the said serial read-out. One way of adapting the type carrier for serial read-out is by adjustment of the set-screws 38, 48, Fig. 7, so as to dispose the right-hand end of the carrier closer to the firing line defined by the hammer heads aligned along a horizontal line than the left-hand end, thereby skewing the axis of the carrier relative to the firing line within a plane parallel to the firing plane. Another way of adapting the carrier for serial read-out is by adjusting the set-screws 37, 47 (Fig. 6, not shown) so as to elevate one end of the carrier and lower the other end thereby skewing the axis of the carrier relative to the hammer firing line within a plane perpendicular to the firing plane. The degree of skew of the carrier axis is such as to provide a time differential between the firing stroke of adjacent hammers, which is equal to the time lag between successive column or control intervals in the read-out cycle. Hammer-impression arrangements.-A plurality of hammers 12, Fig. 1, are supported by a transverse guide bar 25 in a row extending horizontally along the type carrier 10 and are actuated selectively by electromagnetic actuators including a coil 21 and pivotally mounted armature 22 which has an arm engaging the shank of an associated type hammer. The hammers are restored by spring 26 supported by the bar 25.
