Title: Improvements in or relating to radio altimeters
Inventor: CAPELLI MARINO POMPEO GIOVANNI
IPC: G01S7/40
Filed: 1960-09-20
Abstract: 914,679. Frequency-modulated radar. STANDARD TELEPHONES & CABLES Ltd. Sept. 15, 1961 [Sept. 20, 1960], No. 32219/60. Class 40 (7). A frequency-modulated radar altimeter provided with means for continuously checking its operation, comprises a transmitter T connected by a signal path to a first receiver A, a second receiver B connected by signal paths to the transmitter, both directly and via a delay line L, a transmitter antenna C and a first receiver antenna D providing a further signal path between the transmitter and the first receiver, and means for comparing the frequency of output signals from each of the receivers. With ganged switches S1 and S2 in the position shown, the output of receiver B, corresponding to the equivalent height of delay line L is checked against the correct output from source G, whilst movement of the switches to position X connects the checked receiver B in parallel with receiver A through output comparing means E to provide a check on receiver A. In a further embodiment, Fig. 2 (not shown), switches S1 and S2 and source G are dispensed with and the delay line is connected between the first and second receivers on the antenna side, the receivers being checked by means E now seeing that the outputs of the receivers differ by a time corresponding to the delay line. Specification 678,389 is referred to.

Title: Vinyl stearate-maleic anhydride copolymers
IPC: C08F22/04
Filed: 1961-09-07
Abstract: Copolymers of vinyl stearate and maleic anhydride in a molar ratio between 2.8 and 6:1 having a average molecular weight between 1000 and 3000 may be prepared by polymerizing a mixture of 90 to 95% wt. of vinyl stearate and 5 to 10% wt. of maleic anhydride in the presence of a chain transfer agent and a free radical initiator at a temperature of at least 50 DEG C.  Such copolymer may be reacted with a C1-18 alkanol to yield a vinyl stearate-alkyl maleate copolymer having an average molecular weight between 1000 and 5000.  Chain transfer agents specified are ketones, aldehydes and chlorinated hydrocarbons. The less active agents can themselves constitute the sole medium for solvent polymerization but the more active agents require dilution with an inert organic solvent. Initiators specified are benzoyl, lauroyl, butyl, caproyl and cumyl peroxides, butyl hydroperoxide and azobisisobutyronitrile.  The maleic anhydride is added incrementally to the solution of vinyl stearate; the initiator may also be added incrementally.  Polishing compositions: The anhydride copolymers are crystalline waxy materials and are used in polishing compositions which dry to a shine without buffing.  In examples 10% of the anhydride copolymer is dispersed in water containing (Example 6) a mixture of polyoxyethylene adducts of tridecyl alcohol or (Example 7) a mixture of isopropyl ammonium dodecyl benzene sulphonate and a polyoxyethylene adduct of nonyl phenol as dispersing agents and a trace of ammonia added.  The maleic ester copolymers are plasticizers for polyvinyl chloride.

Title: Improvements in or relating to a method of manufacturing sheet glass
IPC: C03B15/06
Filed: 1934-11-09
Abstract: 431,669. Glass manufacture. AMERICAN WINDOW GLASS CO., Farmers Bank Building, 5th Avenue, Pittsburg, U.S.A.- (Assignees of Bishop, F. L.) Nov. 9, 1934, No. 32309. Convention date, Sept. 8. [Class 56] Relates to the method of making sheet glass by drawing a sheet continuously upwards from a bath of molten glass. The invention consists in providing means for causing the air or other gas which is in contact with the rising sheet, particularly with its lower portion, to circulate transversely in order to obtain more uniform annealing. The Figure shows a Fourcault type of apparatus in which a sheet S is drawn from a bath of glass B through a debiteuse 5 situated in a drawing pit 6, the sheet being passed through a leer 8 situated above the pit. The required circulation of the gas may be effected by means of blower nozzles 17, 18 which are placed at the sides of the pit and direct air blasts transversely to the length of the glass sheet. The circulation of air may take place either in the pit or in the lower part of the leer so long as it takes place adjacent to that part of the glass where the temperature is within or above the annealing range. Specification 431,668 is referred to.

Title: Method and means to accelerate the consolidation of clay-ground or other soil
IPC: E02D3/10
Filed: 1947-12-08
Abstract: 632,902. Drainage. KJELLMAN, W. Dec. 8, 1947, No. 32366. Convention date, Jan. 25, 1939. [Class 33] A method of accelerating the consolidation of clayground or other soil having a low perviousness to water consists in placing bandshaped flexible and porous drains of a material pervious to water in interspaced relation substantally vertically into the ground for drawing pore water upwardly from the ground. To carry out the method a thrust pipe 6 containing the band-shaped drain 20 supplied from a roll 16 over a guide roller 18 is pressed down into the ground and is then pulled up to leave the drain behind it by the agency of a chain 12 driven from a motor 8 by way of a sprocket wheel 10. The drain is secured, before the thrust pipe 6 is pressed down, to the flat lower end thereof, for instance, by means of a sleeve 22 arranged thereon formed by a compressed piece of pipe pinched together at the lower end to secure the band. Said sleeve bears on supporting abutments 24 so that the drain participates in the downwardly directed but not in the upwardly directed movement of the thrust pipe 6. Another length of the drain material 20 is introduced into the thrust pipe 6 when the latter is pulled up. The band is then severed below the lower end of the thrust pipe 6 to be secured to this end anew. A pipe 4 serves as a guide for the thrust pipe 6, said pipe 4 being carried by bracing means on a four-wheel truck 2, on which the motor 8, wheel 10 and supply roll 16 are placed.

Patent GB-328613-A (GB)
Abstract: 328,613. Tollemache, H. D. Jan. 31, 1929. Right to Patent relinquished. Monogrammic signals.-The display of each digit of a totalizator total is effected bv means of fixed digital representations made visible in the display space under the selective control of the counting mechanism, the display space being capable of accommodating one digit only at a time. In the form shown in Fig. 2, each display space, B or C, contains a screen F for receiving the projected image of stencilled figures contained in banks of lamps E. The lamps are wired, through a plug-and-socket device G, with a switch H the arm H' of which is rotated by the totalling-mechanism. In the arrangement shown in Fig. 6, a sign of the monogrammic type is utilized and the groups of lamps to be illuminated are controlled by the switch through relays L<4>. In other modifications the monogrammic lamps are replaced by coloured plates or screens moved by solenoids to render the digit visible as in Fig. 9. Thus in Fig. 10, plates N pivoted at 0 are rocked to occupy a vertical or horizontal position and in Fig. 13 white arcuate screens may be moved to obscure black panels S. In Fig. 14 the display space is occupied by drums with halves of their peripheries contrastingly coloured and connected by cords T' with the cores of their operating solenoids. Means may bei provided to interrupt the rotation of the control switch periodically to enable the figures displayed to persist. According to the third Provisional Specification the drums or alternatively flexible bands may be geared together in groups and be actuated by a motor controlled through a hunting-gear.
