Patent GB-684678-A (GB)
Title: Production of shaped articles
IPC: C08K5/29
Filed: 1949-07-19
Abstract: Shaped articles are produced by mixing a polymer or copolymer of vinyl chloride with one or more mono-isocyanates, preferably phenyl isocyanate, working up into shaped articles, with the aid of heat and pressure if desired, and allowing the shaped articles to age to give greater hardness and higher softening-point. Plasticizers such as dibutyl phthalate, fillers and dyestuffs may be incorporated. Cellular products may be obtained by incorporating an expansion agent such as azo-isobutyric acid dinitrile and heating the mix in a closed mould until the expansion agent decomposes, whereafter, after cooling, the mass is allowed to expand and the cellular body formed allowed to age.

Patent GB-707230-A (GB)
Title: Improvements in or relating to the manufacture of aromatic hydroxy aldehydes and derivatives thereof
Inventor: GOLDBERG ALAN AUGUST
IPC: C07C47/56
Filed: 1950-07-31
Abstract: The invention comprises nitrones of the formula <FORM:0707230/IV (b)/1> in which R is a hydrogen atom or a nitro group, R1 is an acyloxy or hydroxy group and Z is a phenyl or para-dialkylamino-phenyl group and their preparation by treating a benzyl pyridinium halide of the formula <FORM:0707230/IV (b)/2> where X is a halogen atom and Y is a hydrogen atom or an alkyl group with an aromatic nitroso compound Z-NO, in the presence of an acid acceptor and also the production of 4-nitrosalicylaldehyde and 4-aminosalicylaldehyde by hydrolysing a nitrone of the above general formula wherein R is a nitro group by a strong acid followed by catalytic reduction with three molecules of hydrogen.  Preferably the nitrone is prepared by the reaction of 4-nitro-2-hydroxy-, or 4-nitro-2-acetoxy-, benzyl pyridinium halide with nitrosobenzene or nitrosodimethylaniline in the presence of caustic alkali.  The 4-nitrosalicylaldehyde obtained by hydrolysis of the nitrones may be converted to an oxime, phenylhydrazone, semi-carbazone or thiosemicarbazone which may be reduced to the corresponding 4 - aminosalicylaldehyde derivative by the action of a mildly alkaline reducing agent (e.g. ammonium or sodium sulphide).  The 4-aminosalicylaldehyde functional derivatives may also be obtained directly by treating 4-aminosalicylaldehyde produced by catalytic reduction of the 4-nitro compound with, e.g. thiosemicarbazide.  In examples: (1) 4-nitro-2-acetoxy benzyl pyridinium bromide is reacted with p-nitroso dimethylaniline in the presence of sodium hydroxide and the resulting reaction mixture is hydrolysed, without isolating the nitrone, to 4-nitro-2-hydroxy benzaldehyde which is converted to the thiosemicarbazone and reduced by ammonia and hydrogen sulphide to 4-aminosalicylaldehyde thiosemicarbazone; (2) 4-nitrosalicylaldehyde, produced as in (1), is catalytically hydrogenated (Raney nickel) and the resulting 4-aminosalicylaldehyde isolated as the thiosemicarbazone; (3) 4 - nitro - 2 - hydroxy benzyl pyridinium bromide is treated with p-nitroso dimethylaniline to give the corresponding nitrone which is hydrolysed to 4-nitrosalicylaldehyde; (4) 4-nitrosalicylaldehyde prepared as in (3) is converted to the thiosemicarbazone and reduced to the corresponding 4-amino compound; and (5) 4-nitro-2-hydroxy benzyl pyridinium bromide is reacted with nitrosobenzene and the product is hydrolysed to give 4-nitrosalicylaldehyde.  Specification 703,687 is referred to.

Title: Improvements in or relating to gyroscope apparatus
Inventor: BARNES JEFFERY WALTON
IPC: G01C19/38
Filed: 1952-08-01
Abstract: 723,377. Gyroscopic apparatus. MINISTER OF SUPPLY. Aug. 4, 1953 [Aug. 1, 1952], No. 19581/52. Class 97 (3). Gyroscopic apparatus in which an accelerating force acting in a direction other than axially or radially of the spin axis of the rotor in the inner gimbal causes the centre of gravity of the gimbal and rotor assembly to move in a direction other than that of the force and so results in the application of a disturbing torque to the gimbal about its pivotal axis, is provided with means whereby said force also causes a compensating torque to act on the gimbal in opposition to the disturbing torque. In the form shown in Fig. 1, the inner gimbal 13 has only one degree of freedom about axes (not shown) perpendicular to the rotor spin axis 11 which is mounted on the gimbal in bearings 12 which are less stiff in the axial than in the radial direction with the result that an accelerating force not acting in either of these directions would result in a disturbing torque about the gimbal axes. To compensate for this torque, a mass 14 is supported by a spring wire 15 on the gimbal 13, the accelerating force causing this mass to move in a direction normal to the rotor spin axis and the gimbal axis. A universallymounted gyroscopic apparatus is shown in Fig. 2, the rotor spin axis bearings being least stiff in the S-S direction and unequally stiff in the X-X and Y-Y directions. To compensate for the disturbing torque that would be produced by an acceleration force acting other than radially or axially of the spin axis S-S, masses 21, 22 supported by spring wires 23, 24 are mounted on the inner gimbal 18. Mass 21 compensates for the torque about the X-X axis and mass 22 for the torque about the Y-Y axis.

Abstract: 1536653 Sonar direction finding CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL 11 May 1964 [21 May 1963] 19610/64 Heading GIG A direction finding system for determining the direction of incoming short sonic or ultrasonic pulses, comprising a plurality of electroacoustic transducers forming a circular arrangement, means for sequentially switching in and out pairs of diametrically opposed transducers for collecting the differential output signal of each pair, and means for deriving the phase of said output signal. As shown in Fig. 9 there are four hydrophone dipoles 1, 2 .... 7, 8 although in practice there would be thirty hydrophones, i.e. fifteen dipoles, serving as the transducers receiving the incoming signals. The dipoles are connected to an electronic switch 31 through a preamplifier and time constant detector 11, 12 ..... 18 whereby the outputs of the dipoles are connected in turn to a differential amplifier 32 followed by a pass-band filter 33 centred on the repetition frequency F of the switching cycles. A clock system 30 operates the switch 31 and also operates a signal generator circuit 34 to produce a squarewave reference signal of frequency F. The output signal from filter 33 is compared in phase with the reference signal in a first phasemeter 35 and with the same signal, delayed by #/2 by a phase shifter 36, in a second phasemeter 37. The output of phasemeter 35 is proportional to cos # and output of phasemeter 37 is proportional to sin # provided that the signal from amplifier 32 is sinusoidal, this latter requirement being met by a suitable construction of the hydrophones. # represents the direction of the incoming sound signals and may be indicated by the direction of a vector 39 on a cathode ray oscilloscope 38. The magnitude of the vector 39 may represent the frequency of the incoming sound signals and to this end a frequency-measuring circuit including a further hydrophone Fig. 11, (not shown) is employed, the signal derived from this circuit and proportional to the sound frequency being applied to the inputs of the phasemeters 35, 37. Each hydrophone, Fig. 1, comprises a pair of ceramic tubes, e.g. 1, 1a, of lead titanate or zirconate mounted in a recess 101 formed in an annular wall, 102 of polyethylene secured to a bronze bush 103.
