Title: Improvements in or relating to perforated strip telegraph transmitters
IPC: H04L17/12
Filed: 1937-12-07
Abstract: 489,597. Controlling telegraph transmitters. SIEMENS & HALSKE AKT.-GES. Dec. 7, 1937, No. 33848. Convention date, Dec. 7, 1936. [Class 40 (iii)] A tape-operated transmitter is automatically brought into operation, after a short delay, when the motor has been switched on, and is unclutched whenever the tape becomes tightened. A keyboard transmitter may be rendered operative in the latter circumstances. The apparatus is shown in the idle position. To start the motor, the latch 7 is tripped and the stirrup 6 moves from position I to position II, turning the shaft 5. A loosely mounted cam 8 is moved by pin-and-slot mechanism to close the motor contacts 9 and to transfer a short-circuit at 10 from the contacts of a keyboard transmitter to those of the tape transmitter. At the right-hand end of the shaft 5, a pin 22 on a lever 20 engages a bent lever 24 and raises a gear 27 into engagement with a gear 17. The motion of the shaft 5 is thereby limited so that the transmitter is not clutched in at this stage, but the gears 17, 27 are driven by pawl-and-ratchet mechanism from a cam 11 on the motor shaft 1, so that the cam 28 rotates anticlockwise until it engages the lever 24, and turns it until it frees the pin 22 and thus permits the shaft 5 to rotate again until the stirrup 6 reaches position III. In this position the pin 22 has turned the clutch lever 2 about a pivot 21 so as to free the element 4 of the friction clutch. The tape runs through the stirrup 6, and, when the tape tightens during transmission, the stirrup 6 and shaft 5 are rotated clockwise, whereupon the transmitter shaft is stopped by the clutch lever 2, but the motor circuit remains closed at 9 owing to the lost motion in the pin-and-slot control of the cam 8. To stop the motor, the stirrup 6 must be returned by hand to the position I.

Title: Improvements in or relating to abrasive grain material of sintered bauxite
IPC: B24D18/00
Filed: 1960-10-07
Abstract: An abrasive granular alumina is made by compacting particles of bauxite into agglomerations, and then sintering at a temperature below the fusion temperature of the bauxite, to induce limited recrystallization of said particles (i.e. crystal growth to about twice the size of the particles in the original powder.)  The grains produced have a generally smooth surface, and the crystals within each grain are randomly orientated, a major proportion of said crystals being in the size range 5-30 microns.  The grains may have a hard surface, and up to one half of the crystals within each grain may be lath-shaped, the remainder being equidimensional. The grains may be composed of a -Al2O3, 3Al2O3,2SiO2, and all of the SiO2 in such grains may be in intersticial relation to the crystals therein. The particles of bauxite used usually have sizes less than 12 microns, and are produced, for example, by ball-milling natural bauxite.  The particle size of the agglomerated material is 4-5 microns, and the grain size of the agglomerate falls within the range 6-16 mesh, a pressure of 5 tons/sq. inch being suitable for producing the agglomerate from the bauxite particles.  The sintering temperature is usually in the range 1375-1570 DEG  C., and the time period of sintering is from 15 minutes to 4 hours or more, the longer time being needed at the lower temperature, and the time also depending on the type of kiln used.  The use of the abrasive grain material by incorporating it into a grinding wheel is described. Specification 755,116 is referred to.ALSO:An abrasive for a grinding wheel consists of a particular abrasive grain dispersed and supported in a resin.  The grains are sintered grains of bauxite, each grain being made up of a plurality of primary bauxite particles which have been recrystallized in situ, said grains having a generally smooth surface and having random crystal orientation therein, a majority of the crystals being from 5 to 30m  in size.  The grains have a hard, shell-like surface, and up to half of the crystals of each grain may be lath-shaped, the remainder being equidimensional. The grains may be composed of a -Al2O3, 3Al2O3.2SiO2, wherein all of the amorphous SiO2 is preferably in interstitial relation to the crystals. Specification 755,116 is referred to.

Abstract: 994,604. Fabrics. AMERICAN AIR FILTER CO. Inc. Sept. 2,1963 [Sept.10, 1962], No. 34600/63. Heading D1K. [Also in Division B8] A rectangular planar filamentous mat is prepared by winding a filament or filaments about a rotating cylindrical former which also gyrates about a further axis which intersects the axis of the former, and cutting the wound filamentous product along a line so that it can be removed from the former and opened out into a mat. Glass filaments 8 are wound on to a drum 2 which is supported and driven so that it rotates about its own axis on shafts 34 while simultaneously driven so that the drum axis gyrates about the common horizontal axis of shafts 16 by which the apparatus is mounted in pedestal 12. Separate drive means 18 and 44 are provided for the gyratory and rotary motions respectively, drive means 44 preferably including a variable speed gear-box so that the ratios of the rotary and gyratory speeds can be selected to ensure that the filaments provide a uniformly distributed and interlaced effect on the drum surface. Resin is usually applied to at least the initial layers of filaments wound on the drum 2 to ensure retention on the drum surface (which may be covered with paper) and spray applicators may be used for this purpose. In the mat produced by cutting along an axial line and unwrapping the filamentous product wound on the former each filament traces at least a portion of an elliptical sine curve whose amplitude is equal to the width of the mat. The lateral edges of the mat may be trimmed off and the mat used as a reinforcing layer in moulded laminated synthetic plastic products.

A single core in a matrix of magnetic cores having bi-stable magnetization properties is selectively switched by applying coincident pulses from a low impedance, constant voltage source to a row and a column winding, the selected core producing a back e.m.f. during its change of state which limits the switching current applied to other cores by the energized row and column windings to a value below their switching current threshold, and the pulses being of such duration that they terminate before the current-reducing effect of the back e.m.f. is dissipated. A matrix of cores is described, Fig. 1 (not shown), having a number of separate read-out conductors associated with different core groups so as to operate as a function table, each row and column winding being provided with a separate voltage source comprising a transformer connected to the anode of a pentode valve. Each transformer produces two voltage pulses of opposite polarities, the first at the commencement of value current which sets the selected core, and the second on termination of valve current which resets the selected core to its initial state. In a modification, Fig. 4, a shorted conductor 63 passes through all the matrix cores such as 55-58 and by its induced current assists in inhibiting switching of unselected cores. It is stated that the use of a constant voltage source permits the parallel connection of respective windings of different core matrices, Fig. 3 (not shown).
