Abstract: 1,051,944. Brominating diene polymers. MONSANTO CHEMICALS Ltd. July 14, 1965 [Sept. 10, 1964], No. 37136/64. Heading C2C. [Also in Division C3] A stable aqueous dispersion of a flame - retardant is prepared by brominating a diene lower polymer that is dispersed in an aqueous medium containing a water-soluble cellulose derivative. The lower polymer may be a dimer, trimer or tetramer-cyclooctadiene and cyclododecatriene being specified. Specified cellulose derivatives are methyl and ethyl cellulose, hydroxymethyl cellulose and carboxymethyl cellulose. The aqueous medium may contain 5 to 30, preferably 10 to 20% of dispersed diene polymer and 0À5 to 6% of the cellulose derivative. The dispersion may be produced by using from 0À5 to 5% of the usual emulsifying agents preferably anionic or non- ionic. The bromination may take place by treating the dispersion with a brominating agent, e.g. bromine (preferred) or N-bromosuccinimide at 10‹ to 75‹ C. In an Example (1) methyl cellulose dissolved in a dispersion of cyclododecatriene in water is agitated while liquid bromine is slowly added and for some time after when a stable white dispersion of brominated cyclodecatriene in water results. The dispersion is acid, but can be neutralized with aqueous ammonia without coagulation.

Abstract: 1,054,988. Golf-practising apparatus. M. R. SPEISER. Aug. 4, 1964 [May 25, 1964], No. 31129/64. Heading A6D. In a projector for use in a golf-practising range such as that disclosed in Specification 1,051,043 the force and direction of a stroke delivered to a ball are signalled to a computer controlling the operation of a projector to project a spot of light representing the ball on to a screen bearing a representation of a golf course. The projector comprises an iris diaphragm 13 which is computer-controlled in response to the force of the stroke delivered to the ball to vary the size of the projected spot of light. From the diaphragm, the light beam passes through tube 52 in which there is mounted a mirror 76 for deflecting the beam on to the screen. The tube is mounted in the projector casing for rotation about a horizontal axis to deflect the beam vertically, and the mirror is mounted for rotation about an axis which is perpendicular to said horizontal axis, to vary the lateral position of the projected light beam on the screen. Rotation of the tube and mirror is effected by electric motors, computer-controlled in response to the drive characteristics imparted to the ball. The speed of operation of the iris diaphragm is automatically varied inversely with the speed of the vertical deflection of the light beam, to give an accurate simulation of distance.

Abstract: 1,225,346. Removing cores from packages. SCHUBERT & SALZER MASCHINENFABRIK A.G. 19 March, 1969, No. 14359/69. Headings D1F and D1J. Apparatus to remove the winding core from a self-supporting yarn package comprises a single pushing means, e.g. a pneumatically operated piston 9, which pushes the package 1 off the core 3 in two or more movements. This is stated to place less strain on the pushing means than in conventional arrangements. The package 1 is first deposited in a trough 2 so that a groove in the core 3 engages a notch 31 in a fork 5, the weight of the package pressing down sprung arm 71 bearing a pusher 7. On retracting the piston 9, another pusher 32 forces the package part way along the core. The piston is then extended, and as it passes the end of the package, arm 71 springs up. The next retraction of the piston then forces the package off the core by means of pusher 7. A second embodiment (Fig. 3, not shown) uses a driven threaded spindle moving a nut to drive a single pusher mounted on a ratchet device.

Abstract: 1,228,480. Sintering ores. NIPPON KOKAN K.K. 1 Oct., 1968 [2 Oct., 1967], No. 46432/68. Heading C1A.  In a method of sintering ores, in which a sintered cake is formed and successive portions break off from said cake, the temperature distribution over the cross-section of the cake exposed when a sintered portion breaks off, e.g. when the cake-carrying pallet or belt changes direction, is measured, and the deviation of said distribution from a predetermined reference profile obtained, one or more factors which influence the sintering accordingly being adjusted in such manner as tends to correct said deviation. The factors which may be adjusted are the pallet speed, the ore/fuel ratio, the quantity of water present, the density of the feed material, the amount of air provided, the grain size of the feed and the nature of the feed material. The temperature profile may be obtained by radiation pyrometers or infra-red cameras, and this profile compared with the reference profile by a computer.

Abstract: 1,231,933. Digital data transmission over telephone lines. SIEMENS A.G. 21 April, 1969 [22 April, 1968], No. 20151/69. Headings H4K and H4P. Data is transmitted from a remote station to a receiving station by way of a telephone network, the remote station by disconnection of its transmitter causing the receiving station to return a signal indicating whether or not data received up to that point has been subject to error so that the data may be repeated or continued. Disconnection of the transmitter connects a loudspeaker to the line so that reverted signals may be heard by an attendant who responds accordingly. The reverted signal may be a tone or a pre-recorded message. The transmitter, Fig. 2, has a keyboard TA for numerical data and a teleprinter, punched tape or card reader AT for alpha-numeric signals. For sending members oscillators S1 and S3 each produce respective 1-out-of-4 frequency codes separated by one of the codes as a spacing signal. Alpha-numeric signals are produced similarly but with the addition of a third 1- out-of-4 code from oscillator S2. Signalling is continuous with no gaps in transmission. An attendant using substation FSP1 at the transmitter sets up a connection to the receiving station which responds by throwing contact K3, Fig. 3, to connect the receiver. The three 1-out-of-4 code channels are separated by filters GF, amplified and limited at GV, and are demodulated and decoded at DM. Presence or absence of a signal on the channels is detected by circuit PU which operates contact K4 periodically to connect up a " ready to send " signal from oscillator RS (or a prerecorded announcement from PV) while providing periods during which the receiver looks out for a received signal. At the transmitter the " readyto-send " signal is heard in the telephone earpiece and the attendant throws K1 and starts transmission. After a period of transmission determined arbitrarily by the attendant, or by automatic means, the key K2 is thrown to disconnect the transmitter and connect loudspeaker LS. At the receiver the loss of signal is detected by PU to connect the signal reverting apparatus RS, PV conditioned by fault recorder FU to send back a signal that reception is satisfactory or at fault. If a fault condition is signalled the transmitter attendant keys a code forward to erase the fault condition recorded in FU so that the " ready-to-send " signal takes its place and transmission is re-initiated. If the receiver detects loss of signal for a period in excess of 20 sees. the connection is released. If the signal reverted from oscillator RS is an out-of-band signal, such as 420 cycles/sec., it need not be switched over contacts K4.
