Abstract: 1,015,309. Combat vehicles. HENSCHEL-WERKE A.G. Oct. 23, 1964 [Nov. 5, 1963], No. 43350/64. Heading F3C. A combat vehicle particularly of the tracked, or all-wheel drive, armoured type of construction and having a heavy weapon, such as a cannon or rocket firing device, built in a turret 2 mounted on the vehicle body 1 so as to be rotatable through 360 degrees, has the axis of rotation 5 of the turret slightly inclined forwardly in relation to the vertical so that the height of the rear part of vehicle body is adequate for accommodating the propulsive mechanism of the vehicle. The driver is accommodated in the turret and his sighting means, such as a periscope, is arranged in the roof of the turret and the look-out part of the sighting means is continuously rotated in a direction opposite to the direction of rotation of the turret by the turret's rotary mount through mechanical, electrical or hydraulic means so that the driver always looks forwards. The look-out port of the sighting means is also adapted to be changed over so that when the vehicle is reversing the driver may also look in the reverse direction. A lateral switching device may also be switched on with the changeover of the look-out port. The driver's periscope and the aiming periscope are established by gyro-control.

Abstract: Compounds are described having the general formula <FORM:1038331/C2/1> wherein R is a group rendering the coupler non-diffusing, R2 is an alkyl group having 1 to 10 carbon atoms, R3 is an alkyl group having 1 to 10 carbon atoms or a phenyl group, R3 in either case containing a carboxy or sulpho group, or R2 and R3 together comprise a heterocylic ring linked to at least one carboxy or sulpho group, and A is -O-, -S-, -CH2NH-, = CH-, or -S-S-.  The compound wherein A is -S-and R is m-octadecyl-carbamyl-phenyl is prepared by saturating carbon tetrachloride with chlorine gas, adding 3,31-dioctadecylcarbamyl-diphenyl-disulphide, removing excess chlorine and refluxing with 1-hydroxy-N-ethyl-31,51-dicarbomethoxy - 2 - naphthanilide.  The ester groups are then hydrolyzed to the free acid with sodium hydroxide.  Other compounds are similarly prepared wherein A is -S-, R is phenyl substituted by tridecylcarbamyl, diheptylcarbamyl or a  - (2,4 - di - t - amylphenoxy) butylcarbamyl, R2 is ethyl or isopropyl and R3 is dicarboxyphenyl or p-sulphophenyl. Another compound is prepared by reacting p-nitrobenzene sulphonyl chloride with 1-hydroxy-N-(3,5 - dicarbomethoxyphenyl) - N - ethyl - 2-naphthamide and reducing the nitro group to the corresponding amine which is then reacted with p - octadecyloxybenzaldehyde, followed by reduction of the Schiffs base and hydrolysis of the ester groups to free acid with sodium hydroxide.  A compound wherein A is <FORM:1038331/C2/2> and links a p-octadecyloxyphenyl group to two naphthanilide residues is prepared by reacting p-octadecyloxybenzaldehyde with 1-hydroxy-N - ethyl - 31;51 - dicarbomethoxy - 2 - naphthanilide in chloroform in the presence of b -mercaptopropionic acid, the solution being saturated with hydrogen chloride gas.  After reaction, the ester groups are hydrolyzed. Compounds wherein R is alkyl of 12-18 carbon atoms or b -(2,4-di-t-amylphenoxy) ethyl and A is -O- are prepared by etherification of 1,4-dihydroxy-2-naphthoic acid with the appropriate alcohol (ROH) to introduce the group -O-R, forming the acid chloride with thionyl chloride, and reacting this with dimethyl-N-ethylamino-iso-phthalate l followed by hydrolysis of the ester groups.

Abstract: 1,125,316. Change - speed friction gear. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 21 Oot., 1965 [24 Oct., 1964], No. 44620/65. Heading F2D. In a record player turntable drive changespeed gear, wherein a friction idler 5 in engagement with the inner or outer periphery or, as shown, the lower face of a turntable rim 2 is spring-urged into engagement with a stepped electric driving motor shaft 6, the idler 5 is carried by a lever 8 which is biased by springs 16, 13 and is pivoted on a pin 11 which is bent up from a shift-rod 12 and, to axially move the idler for ratio-shift, selectively displaceable by the shift rod along a fixed slot 14 having a sawtoothed edge. During ratio-shift the sawtoothed edge of the slot 14 cams the pin away from and then towards the motor shaft axis, an abutment 24 being engageable by an arm 18 of the lever so that said camming of the pin causes the lever 8 to swing the friction wheel out of and then into engagement with the shaft 6. The abutment 24 is bent up from a lever 19 contacting a pin 22 which is movable in a sawtoothed slot 25 and leftwardly shiftable to allow a spring 21 to rotate the lever 19 which in turn then rotates the lever 8 about the pin 11 so as to disengage the idler 5 from the motor shaft when the record player is not in use. The pin 22 may be coupled to the record player main switch.

[Also in Division H3] The non-linear magnetic element of a parametrically-excited resonator comprises one or two cores of thin magnetic film to which the oscillation and excitation windings are coupled. A two-core element is shown in Fig. 3(A) in which rectangular magnetic thin films T are mounted on respective substrates B, and the oscillation and excitation windings Lo, Le each comprise two coils Lo1, Lo2 and Le1, Le2, the coils being arranged so that the excitation and oscillation fluxes oppose in one core and augment in the other. A condenser C is connected across the oscillation winding, and the use of an excitation frequency 2f and oscillation frequency f is suggested. In a modification, Fig. 3(B) (not shown), disc-shaped films are employed. A single film T is common to the excitation and oscillation windings in Fig. 4, one winding in this case comprising a single coil only. The windings may be formed by parelleled or strip conductors, Figs. 7 and 8 (not shown). The magnetic thin film T may alternatively be formed on opposite faces of a rectangular-section substrate or may completely encircle the substrate, Figs. 10(A) and 10(B) (not shown). Use of a circular-section substrate is also described, the film partially or wholly covering the circular surface, Figs. 12(A)- 12(D) (not shown). A two-core embodiment is shown in Fig. 13 in which the winding coils Lo1, Lo2 and Le1, Le2 are mounted on thin hollow mica frames K, thin magnetic films T unsupported by substrates being inserted in the hollow frames after assembly. The oscillation winding may be formed by evaporative depositing, Figs. 14(A), (B), (C) and (E). As shown, a glass or ceramic substrate Ba having bevelled edges B1a, B2a, has a deposited film W of copper or aluminium which is covered with an etching-resistive film and photo-etched so as to leave a diagonal wiring pattern w. Two prepared substrates are then assembled face to face with a thin magnetic film T between them and the wiring patterns adjacent the film. The ends of the wires are raised from the bevelled edges and secured together by solder or a conductive bonding agent, this operation forming the oscillation winding Lo. The assembly is then overwound by an excitation winding Le which could be formed also by evaporative deposition. Alternatively, the wiring w may be formed by using a slitted mask during the deposition process. Electrically insulating films of SiO 2  or MgF may be used if required. The assembly may be formed, Figs. 15(A) and 15(B), by printing the wiring w on a foldable substrate. After folding to enclose the magnetic film T, theends of the wires are joined together. The magnetic thin film in the various embodiments may have an easy axis of magnetization, in which case a biasing field is provided and the angle between the exciting field and the easy axis has a value between 40 and 90 degrees.

Neutron flux in the marginal zone is lower and thus radiation damage to the graphite reflector is reduced. The charge may comprise fuel spheres and graphite spheres, the proportion of graphite spheres being greater in the marginal zone 9. The outer coolant pipes 18 may be throttled so as to increase the temperature of the gas passing through the marginal zone. Spheres may be withdrawn continuously at 3 at a rate such that the desired final burnup is achieved with a single passage through the reactor.
