Title: Mineral wool
IPC: C03C25/255
Filed: 1948-02-16
Abstract: 639,436. Slagwool. TRIGGS, W. W. (National Gypsum Co.). Feb. 16, 1948, No. 4442. Drawings to Specification. [Class 56] Mineral wool fibres resistant to wetting by water are made by distributing dry, finelydivided water insoluble soaps over them while subjecting them to frictional agitation. Thus, stearates, palmitates, oleates, &c. of heavy metals or of aluminium or zinc may be applied through a dusting sieve suspended over an endless belt carrying the wool from a fibrizing chamber, the rate of application being regulated to between 0.25 and 2 per cent by weight of the wool ; the frictional agitation to distribute the soap uniformly may be applied by a granulator which discharges into a rotary cylindrical screen allowing passage of the shot and granules through its orifices while discharging the loose wool from its end. Powdered limestone, e.g. to an amount between 0.25 and 2.5 per cent by weight of the wool may also be applied prior to the frictional agitation to increase fluffiness.

[Also in Division H4] In an interrogator-response system of the type disclosed in Specification 917,755, e.g. for identifying railway wagons, wherein the interrogator transmits a single sideband signal representing a radio - frequency carrier modulated by a plurality of discrete audiofrequencies, the responder includes a tuned circuit to receive the radio-frequency carrier and sideband signals, at least one crystal filter being connected to the tuned circuit and tuned to eliminate at least one of the sideband signals. The remaining signals are demodulated and the rectified carrier utilized to power a transistor oscillator and the remaining audiofrequency signals resulting from demodulation used to modulate the transistor oscillator in the manner disclosed in Specification 973,695 to provide a response signal identifying the responder. The interrogator may be a conventional single sideband transmitter modulated by a plurality of discrete audio-frequency signals or may be of a type wherein a carrier frequency oscillator and a plurality of further radio-frequency oscillators have their outputs combined in such proportions that the combined signal is equivalent to a single sideband signal modulated by a plurality of discrete audiofrequency signals.

Abstract: 1,199,524. Price computers. ROCKWELL MFG. CO. 30 Jan., 1968 [17 Feb., 1967 (2)], No. 4617/68. Heading G4D. A price computer, especially for liquiddispensing apparatus comprises two gear stacks with one and two pick-off gears respectively, the combined outputs of the two pick-off gears being subtracted from that of the one pick-off gear. Fluid-flow input 22 or 24 drives a volume indicator 116 and also two gear stacks 32, 58. Pick-off gear 34 is adjusted to one step higher than the tens of cents price. Pick-off gears 60, 62 are adjusted to decrease the price by the appropriate numbers of cents and tenths of cents. The outputs of 60 and 62 are successively subtracted from the output of 34 in planetary systems 48, 82 to give the required total price at 96. Step-by-step adjustment of a unit price wheel 256, Fig. 7, rotates a cam 264 to lift a pickoff gear 228 from its stack, a helical drive 262, 266 then moving a rack 274, after which the cam 264 lowers the gear 228 into engagement with the next gear of the stack.

Title: Manufacture of salts of terephthalic acid
Inventor: EDINGTON ROBERT ALEXANDER
IPC: C07C51/41
Filed: 1956-02-15
Abstract: Alkali metal terephthalates are prepared by heating an alkali metal salt of pyromellitic acid to an elevated temperature in the presence of water.  The preferred salt is the tetrapotassium salt although the sodium, lithium or rubidium salts may be used.  The water may be formed in situ by, for example, treating the acid anhydride with the alkali metal bicarbonate.  The reaction takes place in the presence of a heavy metal catalyst and the mixture is heated in the region of 425 DEG  C. in an inert atmosphere such as carbon dioxide or nitrogen.  The terephthalic acid may be obtained from the alkali metal salt by acidification with a mineral acid. An example describes the process using pyromellitic acid anhydride, and potassium bicarbonate with cadmium benzoate as catalyst.

Abstract: 557,382. Circular looms. BALSACH, J. April 10, 1942, No. 4739. Convention date, April 10, 1941. [Classes 142 (ii) and 142 (iii)] A circular loom is provided with means for absorbing the shock in the sections of the reed, for compensating for differences in tensions in the threads forming the warp, for coupling together and braking the warp bobbins and for providing sufficient weft for weaving when the stop motion operates upon emptying of the shuttle. The reed sections 8 are operated by rollers 19 engaging a cam 20, and the rollers are held against the cam by springs 24 acting upon levers 23 linked by members 22, 16 to the reed sections. The springs 24 can be simultaneously adjusted by rotating a screw 27 engaging the fixed central shaft 28 of the loom. The tension in the warp threads is kept uniform by passing them under and over resilient rings 3, 4 mounted in guides 32, 33. The warp bobbins 2 are connected together by bevel gearing 34 and are supported by bearings 35, one bearing for each bobbin having its cover pressed against the bobbin spindle by a spring 36 and serving as a brake. The weft unwinding from the cop 40 passes through a lever 42 forming part of a stop motion, and it provides a length of weft available for weaving when the lever 42 acts upon absence of weft on the cop, the weft 43 is led from the lever 42 to an eye at the opposite end of the shuttle before passing to the fabric.

A television cathode-ray tube projection system employing a folded Schmidt optical system is modified to include a rotating colour filter disc. Thus, as shown in Fig. 2 and 3, the cathode-ray tube 5 is arranged in an aperture 2 in an inclined plane mirror 6 and projects onto concave mirror 7, the reflected rays being directed by way of mirror 6 and correcting plate 8 onto a viewing screen 9. To accommodate a colour disc 1 formed of red, green and blue filters, Fig. 1 (not shown), the plane mirror is slotted as shown at 3 and the disc is introduced into the slit to such an extent that each filter can pass completely in front of the tube. The disc is driven by a motor 10 by an arrangement as shown in Fig. 4 in which the disc is carried by a shaft 12 coupled to the motor shaft 14 by cord 13. Shaft 12 is carried by an arm 16 pivoted in a base 18 and the filter disc may be rocked out of the light path from the cathoderay tube by rotating rod 19 to permit normal black-and-white image projection. The casing 11 of motor 10 is rotatable by knob 20 to control colour phasing.

Tripod mounts for machine guns.- Consists mainly in mounting the gun in two cheeks pivotally attached to a central socket for the vertical pivot of the gun, the hub of the vertical pivot adjustably carrying the tripod legs by a single clamping bolt. In the form shown in Figs. 1 and 2, the gun is pivotally mounted on a trunnion pin 9 in a pair of cheek plates 6 which are braced together by transverse bolts 12 so as to embrace the flat sides of a socket member 3 relatively to which the cheeks and the gun together can pivot on a pin 5, a clamp 8 engaging sector plates 19 to fix the gun at the desired angle. The socket member can turn on a vertical pivot post 4 fitted with a groove into which a block 19 is pressed by a clamp 18 to fix the gun in training. The gun can be elevated with respect to the cheeks 6 by a differential screw gear, the nut 13 of which swivels in the cheeks, the hand-wheel 15 carrying an external left-hand screw engaging this nut and an internal right-hand screw engaging a bolt member 16. This bolt has a groove fitting behind an extension 10 on the gun and side pins engaging slots in the cheeks. The vertical pivot 4 carries an eye 20 with serrated faces engaging a fork on the rear leg 21, corresponding serrated faces on the front legs 22 and 23 engaging the fork, the legs being thus connected to the vertical pivot by a single clamping bolt 24, Fig. 2. The bolt carries an elongated washer 27 and a similar nut 28 each having rounded edges engaging a concave recess in the upper part of the front legs. The bolt 24 passes through an elongated slot in each of the front legs to permit of them being folded against the rear leg for transport.
