Azines specified are dimethylketazine, diphenylketazine, sym. and unsym. methyl phenyl ketazine, dicyclohexylketazine, acetalazine, benzalazine, and furfuralazine.  Monomers specified are ethylene, propylene, butylenes, tetrafluoroethylene vinyl fluoride, vinylidene fluoride, vinyl chloride, acetate, propionate, benzoate, isobutyrate, thiolacetate, dimethylacetate, trimethylacetate, laurate and hexenoate, vinyl methyl ketone, ethyl isopropenyl ketone, vinylidene chloride, styrene, acrylic and methacrylic acids and esters, nitriles, amides and anhydrides thereof, N-vinylphthalimide and N-vinylsuccinimide.  The process may be carried out under pressure, with agitation, in bulk or with an inert liquid present, those specified being benzene, isooctane, toluene, t-butyl alcohol, ethers or water alone or admixed with the above liquids.

Abstract: 1518080 Train control HAWKER SIDDELY DYNAMICS Ltd 12 June 1975 [28 May 1974] 23578/74 Heading B7N In an arrangement for controlling vehicles moving on a track 12, each track section has associated therewith an operating computer for controlling vehicle movement and a protection computer for monitoring safe operation. Line wire 15 extends along the track section and is directly coupled to the computers by transmit/receive unit 29 and to a vehicle 11 in the section by aerial 16 and transmit/receive unit 17. Both computers receive speed and distance travelled information from tachometer and odometer 18 on the vehicle and information from vehicle interrogation unit 19 as this passes passive transponders 21, 22 on the track and also receive vehicle passage information from trackside interrogation units 23 as these detect passive transponders 20 on passing vehicles. The computers exchange information to enable their operation to be cross checked. Computer 25 sends vehicle speed commands over link 30 to unit 29 for transmission to the vehicle and the protection computer 26 sends via link 31 an enabling tone to unit 29 for transmission to the vehicle or a signal to inhibit operation of unit 29. Both computers can actuate a vehicle power cut-out unit 32. The vehicle has a speed control system which responds to the speed commands and retroactively controls the vehicle speed to meet the commands.

When it is desired to move the spud 4 relative to the hull 5, teeth 14 on a crosshead 3 secured to the rod of the piston 1 are engaged with a rack on the spud and fluid pressure from duct 23 or 24 passes through cylinder 7 and either duct 12 or 13 to the cylinder 1. Teeth 14a on a crosshead 11 secured to the rod 10 can then be engaged with the rack on the spud to permit the teeth 14 on the crosshead 3 to be withdrawn from the rack to enable the position of the crosshead 3 to be adjusted before reengagement with the rack for another movement of the spud. The ducts 12, 13 between the cylinders 4, 7 ensure that any disturbances caused by wave or other motion results in equal displacements of the pistons 1, 6 of the displacements being damped by the third piston-andcylinder assembly 8, 9. In an alternative embodiment, the crossheads are provided with pins engaging holes in the spuds.

Abstract: 666,061. Thermally-operated devices. TIGRETT, J. B. Aug. 27, 1947 [July 29, 1939], No. 23745/47. Class 69 (i) [Also in Group XIII] A thermally-operated device comprises a tube 12 having a condensing portion 13 at one end and a volatilising portion 14 at the other, the whole being at least partially evacuated, a balancing means 9 supporting the tube at a point between the ends so that the volatilising portion is always below the horizontal, and a volatile liquid in the volatilising portion, so that, on maintaining a temperature difference between the two ends, liquid is evaporated in the volatilising portion, some of the liquid and , vapour being transferred to the condensing portion causing the device to become out of balance and to move the condensing portion downwards ; on condensation of the vapour to liquid the latter flows by gravity to the vaporising portion and the cycle is repeated. The condensing portion may dip into a receptacle containing water as a coolant. The tube may be provided with a cover 23 and feathers 26, while the condensing portion may have a metal portion 16 containing a wick which covers the condensing portion, the whole giving the effect of a drinking bird.

Abstract: 426,594. Flexible tubes. LOEWEN. STEIN, F., 8, Krugerstrasse, and LIEBERMANN, J., 6, Herrengasse, both in Vienna, Aug. 17, 1934, No. 23773. [Class 99 (ii)] A flexible tube &c., made by rolling sheets or winding strips of cellulose or other fibrous material 2 about a helical reinforcing wire 1 located on a mandril, is provided with a continuous braided, woven, &c. sheath 3. The said sheath is produced on a textile machine from fibrous material or fine wire, and it serves to press the raised portions of the tube wall against the wire 1, which supports these raised portions from within, so that the wall is gripped along a helical line between the sheath and wire, thus preventing unwrapping of the tube wall. The tube may also be reinforced by a tensionless or elastic thread 4 located in the outer groove of the tube wall, and the fibrous material 2 and the sheath 3 may be impregnated with oil, paraffin, or glycerine.
Patent GB-1368211-A (GB)
Title: Method and apparatus for transmitting command signals
IPC: H04K1/00
Filed: 1972-05-19
Abstract: 1368211 Selective signalling MESSERSCHMITT BOLKOW-BLOHM GmbH 19 May 197223775/72 Heading G4H [Also in Division H4] Analogue command signals are coded with a random (or pseudo-random) binary signal in a transmitter and transmitted to a receiver where they are stored and compared with stored references, producing a command signal when a certain measure of agreement exists, the references having been supplied from the transmitter. In a transmitter, four channels (analogue voltage inputs) are sampled in turn, repeatedly, each sample being digitized, then coded into a group of bits representing both the digital value and the identity of the channel, then supplied to a modulator via a respective shift register. The group of bits is given a pseudo-random form by feedback with modulo-two addition in the shift register (or prior to entry into the register by logic responsive to the output of a noise generator fed through a limiter). In the modulator, the bit values are each converted to one of two frequencies which are modulated on to an intermediate carrier which is then modulated on to a carrier, this carrier itself being frequencymodulated on to a carrier, this carrier itself being frequency-modulated under control of a pseudo-random sequence. The resulting signal is transmitted by radio to a receiver, e.g. in a missile, where after demodulation (including removal of the pseudo-randomity produced in the modulator) the bit stream is inserted into each of a number of shift registers (one per possible group of bits that could be sent), each shift register being correlated with a reference signal in a respective further shift register, equality being detected by a threshold switch to actuate a respective input of a digital-toanalogue converter respective to the channel to produce an analogue control output. Before launch of the missile, all the possible command signals are transmitted and loaded into the further shift registers as references, then transmitted again and loaded into the other receiver shift registers in the normal way as a check, the threshold switch outputs being sent back to the receiver. Timing circuits in the transmitter and receiver are also synchronized at this time, and the transmitter informs the receiver of the pseudo-random sequence used in the modulator. In these pre-launch operations, transmission is via an umbilical cord rather than radio. The analogue samples can alternatively be transmitted by pulse position modulation, by sending a start code-group followed after the appropriate interval by a stop code-group, the start codegroup also indicating the polarity of the sample. The code-groups also indicate the channel and have the psuedo-random feature. Since the sample may be zero and the start and stop codegroups could not be sent simultaneously, the stop code-group is delayed at the transmitter and the start code-group is delayed equally at the receiver.
