Title: An improved process and device for spinning and after-treating artificial silk
IPC: D01D10/04
Filed: 1931-04-20
Abstract: <PICT:0370666/IV/1> <PICT:0370666/IV/2> <PICT:0370666/IV/3> Artificial silk is spun continuously with its production on to a fabric arranged on a winding member and projecting over both ends of the winding member.  After a convenient amount of silk has been wound, the ends of the fabric are wrapped over the artificial silk and the package is withdrawn from the winding member and subjected to washing, deacidification, desulphurization, bleaching, drying, or other treatment.  For the readier withdrawal of the package, strips are laid on the winding member beneath the fabric prior to winding. The fabric may be in the form of a knitted tube.  On completion of the after-treatments, the tubular fabric containing the spun material is mounted on a receiving member and after turning back the ends of the fabric, the filament may be withdrawn and respooled.  The receiving member may be stationary or may be rotated and the filament twisted by overhead withdrawal.  As shown in the drawings, a knitted tubular fabric b is placed over a winding member a and the filament c is wound thereon.  For readier withdrawal of the package, crossed strips h are laid on the member a and connected together at one end by a ring i.  The winding member is preferably made conical so as to facilitate removal of the wound package.

[Class 87 (ii)] An extrusion machine for moulding pellets from meals, mashes, and the like for use as poultry and cattle food comprises rollers 8 contacting with and interposed between two dies 5, 6. The dies are fixedly mounted respectively on coaxial shafts 25, 28 adapted to be rotated at equal speeds in opposite directions by gearing 36, 43, 65, 66 from a drive shaft 62. There may be four rollers 8 arranged symmetrically around the axes of the dies 5, 6 in bearing blocks 13 mounted in apertures in a housing 2. The blocks 13 and rollers 8 may be removed directly from the housing for adjustment or replacement, and the blocks have flanges 16 provided with slots for reception of bolts for securing to flanges 17 on the housing. The blocks carry scrapers 20 in contact with the surfaces of the rollers and the position of the blocks and the scrapers with respect to the dies can be circularly adjusted by means of the slots in the flanges 16 so that the thickness of material spread upon the dies by the scrapers can be varied. Plates overlying the ends of the rollers may be provided at the free ends of the scrapers. The material is extruded through apertures in the dies and cut up into pellets by knives 56 mounted in the housing. The pellets may fall on to an endless conveyer. The material may be fed to an opening in the housing by a shoot from a combined heater and mixer. The peripheries of the dies 5, 6 are provided with rings 23 having spiral threads which prevent material passing around the edges of the dies, the threads on rotation conducting the material back within the housing. The dies are yieldingly mgly held in contact with the rollers by means of the shafts 25, 38. The shaft 25 is supported at one end in a sleeve 26 formed with a cup 52 and a spring 53 is interposed within the cup between it and a washer 54 on the shaft 25.

Title: Catalyst
IPC: C07C5/32
Filed: 1958-04-14
Abstract: Olefinic hydrocarbons with at least four carbon atoms in the olefinic chain (particularly n-butylene) are dehydrogenated, in the presence of steam, at 550-750 DEG  C., by passage through a static bed of pelleted Ca, Ni, phosphate-Cr oxide catalyst.  The latter contains phosphate radicals chemically combined with Ca and Ni (6-12, preferably 7.5-9.0 atoms of Ca per Ni atom) and the amount of Cr oxide is less than 30% (preferably 0.5-5%) of the total weight of Cr oxide + Ca, Ni phosphate.  The catalyst is prepared by precipitating the Ca, Ni phosphate from an aqueous solution of Ca and Ni compounds and on orthophosphate under non-acidic conditions (after precipitation, pH is preferably 7.5-9.0), separating the precipitate, washing and admixing it with up to 30% (preferably 10-20%) of a diatomaceous earth (which may be chemically modified), drying and intimately mixing the finely comminuted composition with finely comminuted Cr oxide and a removable lubricant (e.g. powdered graphite), then forming pellets and removing said lubricant; it is preferable to use ammonia as precipitating agent.  It is stated that the use of diatomaceous earth permits the production of harder catalyst pellets.  The mixture of undried precipitated Ca, Ni phosphate with up to 30% diatomaceous earth is claimed per se. U.S.A. Specifications 2,456,367, 2,456,368 and 2,542,813 are referred to.

Title: Electronic ringing current generator
IPC: H04M19/02
Filed: 1953-05-04
Abstract: 740,258. Automatic exchange equipment. AUTOMATIC ELECTRIC LABORATORIES, Inc. May 4, 1953 [June 13, 1952], No. 12356/53. Class 40 (4). In an electronic ringing generator comprising a plurality of tuning circuits which are switched sequentially to produce a succession of different frequencies, electrical disturbances resulting from the switching are suppressed, a ring-back tone from a generator controlled in response to actuation of the ringing generator is superimposed on each ringing signal, and the composite signal is amplified. The resistancecapacity Wien oscillator 231 comprises valves. 237, 244 having the usual cross-connection of plates and grids, and one of the cross-connections, namely that from the plate of valve 244, includes tuning circuit 491 comprising a series of pre-set variable resistors which are sequentially connected by relays 445-449 in response to the actuation of switches 464-468 by cams 401-405 on the shaft 406 of motor 400. The oscillatory circuit is completed by a resistor 238 between the plate of valve 244 and the cathode of valve 237 and a circuit from the grid of valve 237 to the cathode of valve 244 which includes the lower block of variable resistors 426, 427 . . . of the tuning circuit 491. The oscillator output which is taken across condenser 246 passes via a buffer amplifier 252 and a phase-inverter 264 to a push-pull driver stage, whence it is fed to a final amplifier comprising valves 290, 293, 296 and 299 in parallel push-pull. Contacts of relays 445-449 in the feed to the exchange equipment ensure that one ringing current is interrupted before the succeeding current is connected. The ring- back tone generator 320 comprises a 400-cycle oscillator 322 which is normally rendered inoperative by a - ve bias from the power source, and a 40-cycle oscillator 321 comprising a double-triode valve 330 connected as a multivibrator. The arrangement is such that the oscillator 322 breaks into operation only when the + ve half-cycles from oscillator 321 overcome the negative bias and the 400/40 cycle signal thus derived is applied with the ringing current to the buffer amplifier 252. Transients arising from the switching are suppressed by a non-linear resistor 279 connected between the control grids of valves 278, 282, which comprise the driver stage. Ringing frequencies suggested are 16 2/3 25, 33< >1/3, 50 and 66< >2/3 cycles per second and their duration is stated to be of the order of one second. Specification 687,632, [Group XXXVIII], is referred to.
