Title: Dyestuffs of the phthaloyl-isoindolenine series
IPC: C09B5/24
Filed: 1958-11-19
Abstract: The invention comprises dyestuffs which in one of their tautomeric forms have the formula <FORM:0899709/IV (c)/1> where R1 is oxygen, R2 is hydrogen or alkyl, and R3 is a cycloaliphatic or unsubstituted aliphatic radical or an aliphatic hydrocarbon radical substituted by halogen, hydroxy, alkoxy, amino or alkylamino, or where R1 is imino or =NR4, R2 is hydrogen and R3 and R4 which may be the same or different are aromatic, cycloaliphatic or unsubstituted aliphatic radicals or aliphatic hydrocarbon radicals substituted by halogen, hydroxy, alkoxy, amino or alkylamino, and R5 and R6 are hydrogen, chlorine, hydroxy, alkoxy, amino or acylamino.  The dyes where R1 is imino or =NR4, R4 being the same as R3, and R2 is hydrogen are made by reacting an appropriate 1 - alkoxy - 3 - imino - 4 : 7 - diamino - 5 : 6 - phthaloyl-isoindolenine with an amine of the formula R3NH2, the reaction being conducted at a temperature above about 100 DEG C. when R1 is to be an =NR4 group.  When R4 is to be different to R3, the indolenine is reacted in a molar ratio of about 1 : 1 with the amine R3NH2, and the product is then reacted in a molar ratio of about 1 : 1 with an amine R4NH2 at a temperature above about 100 DEG C.  Dyestuffs where R1 is oxygen and R2 is hydrogen are made by reacting an appropriate 1-hydroxy-3-imino-4 : 7-diamino-5 : 6-phthaloyl-isoindolenine with an amine R3NH2 and the dyestuffs where R1 is oxygen and R2 is alkyl are made by reacting an appropriate 1 - oxo - 2 - alkyl - 3 - imino - 4 : 7 - diamino - 5 : 6 - phthaloyl - isoindoline with the amine R3NH2.  Examples are given.  The dyestuffs dye textile fibres of polyamides, polyesters and acrylic acid nitrile in blue shades.

Title: Vehicular radio receiver for both amplitude and frequency modulation reception

Filed: 1963-09-30
Abstract: 1,005,417. Frequency and amplitude modulation receivers; automatic frequency control systems; semi-conductor circuits. BENDIX CORPORATION. Sept. 30, 1963 [Oct. 8, 1962], No. 38432/63. Headings H3A, H3Q, H3R and H3T. In a combined F.M./A.M. transistor radio receiver three F.M./I.F. stages are respectively used as an R.F. amplifier, converter and I.F. amplifier for A.M. reception. F.M. signals are applied through inductively tuned, parallel resonant, emtiter and collector circuits of a R.F. transistor 34 to a mixer 56 supplied also on its base with inductively tuned oscillations from a local oscillator 66. The I.F. is then amplified in three neutralized I.F. amplifiers 100, 124, 140, and after limiting by transistor 158 detected and applied to a lowfrequency amplifier and output stage 308. The R.F. output is shunted by a circuit 62, 64 series resonant at the I.F. to increase stability, and a noise limiter 108, 110 shunts the mixer output. During A.M. reception A.M. signals build up in an inductively tuned antenna circuit 18 shortcircuited by a switch 190 during F.M. reception, and pass via a series resonant inductively tuned circuit 199, 202 and transformer secondary 98 to the base of the F.M./I.F. transistor 100 now acting as an A.M./R.F. stage with inductively tuned parallel resonant collector circuit 120, 122 feeding the base of the second F.M./I.F. transistor 124 now switched to act as a selfoscillating mixer. During A.M. reception the F.M. mixer transistor 56 has its collector circuit shorted to earth by a switch 120 and during F.M. reception this switch 120 short-circuits the A.M./R.F. tuned circuit 120, 122. The A.M. mixer 124 oscillates since a switch 206 now cuts out the F.M./I.F. transformer and neutralizing lead and connects the collector to a A.M./I.F. transformer 208 and an inductively tuned collector circuit 214 with oscillation maintaining feed-back to the emitter of transistor 124. The A.M./I.F. transformer 208 feeds the transistor 140 with collector circuit now switched from the F.M./I.F. transformer to the A.M./I.F. transformer 222 and A.M. detector 224 and the switch 188 now connects this A.M. detector 224 instead of the F.M. discriminator 174, 178 to the low-frequency amplifier and output. A diode 240 provides A.G.C. for the A.M./R.F. stage 100. Positive supply voltage is supplied to the transistor emitter circuits through a self-heating safety resistor 268. An A.F.C. voltage is also derived by the F.M. discriminator and applied to a voltage variable capacitor diode 334 in the F.M. local oscillator. Since voltage supply variations would vary the frequency of this local oscillator, a compensating voltage variation is applied to the other side of the diode capacitor 334 from a supply line including in series a voltage dropping Zener diode 320.

Surfaces 20, 40 on the member 11 and hub respectively are normally separated by a gap of 0À004-0À02 inch, but under extreme loading of a vehicle these surfaces contact over a portion of their circumferences to prevent undue distortion of the body member 11. Pins (not shown) on the hub engage in holes (17) (Fig. 1, not shown) in flange 13 when the body member is applied to the hub. Each rim part 24 includes axially inner and outer portions 27, 28 which are welded at 29. The base of each rim part is inclined at an angle of approximately 6 degrees with a line parallel to the wheel axis. The portions 33 of the rim parts are rolled. When used with a tubeless beaded tyre a sealing ring is positioned between flanges 30.

[Also in Division B8]  In a method of manufacturing block bottom bags, a web of material has margins 2, 3 folded longitudinally and is cut into lengths which are folded transversely three times to produce a seamless block bottom. The side walls a, b and margins 2, 3 are superposed and secured by previously applied adhesive. Tabs 5, 6 which fold back on to the margins may be provided. In one embodiment of a machine, Fig. 7, a blank 1 is fed through three pairs of folding- blade and folding-gripper cylinders 10a, 10b, 11a, 11b, 12a and 12b, each pair producing the folds I, II and III respectively, Fig. 4. After formation of the fold I, elements 14a, 14b grip the blank at the position of the fold II and the area between I and II is held by suction means 16 on the cylinder 11a, so that as the blank advances this area is folded back on the blank trailing portion. The blank is pulled off the suction means by continued rotation of the cylinder 11b and passes beneath a deflecting roller 17 to elements 15a, 15b which grip it at III. The leading portion initially passes above a roller 18 but is then pulled beneath it by continued rotation of the cylinder 12b to produce the formation shown in Fig. 4c. In a further embodiment, the final fold elements grip the blank on the trailing side of the folds I, II, Fig. 11, to produce the formation shown in Fig. 5. Another machine to produce this formation includes a stationary suction gripper, Fig. 13 (not shown), for engaging the area destined to form the bottom while the blank is advanced by the preceeding cylinders to produce the second fold. A sector consolidates the folds and a final pair of cylinders superpose the side walls. In another variant, the lower cylinders of the machine of Fig. 7 may be replaced by a single cylinder with the upper cylinders grouped around it (Fig. 15, not shown).
