IPC: F25B39/02
Filed: 1918-12-10
Abstract: 136,602. Langbert, E. G. E. Dec. 10, 1918. Cold-accumulators for use in refrigerator cars or other cooling-chambers comprise a vessel 5 containing brine or the like surrounded by a gilled or like casing 1 containing liquefied sulphurous acid, ethyl chloride, or other refrigerant. The vapour from the refrigerant in the space between the vessel and casing is drawn off by a pump &c. through a pipe 2, which connects with a series of cold-accumulators, and the liquefied refrigerant is supplied by a pipe 10. In normal working, the refrigerant acts as the cooling- medium in the room, by transfer of beat through the wall of the casing, and also serves to freeze the brine in the inner vessel. When the plant producing evaporation of the refrigerant is idle, the brine acts as a reserve cooling-agent, the refrigerant in the annular space serving merely as a conducting-medium.

Title: A binary information transfer device
IPC: H03K17/84
Filed: 1961-06-09
Abstract: 912,314. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 9, 1961 [June 24, 1960], No. 20888/61. Class 38 (2). [Also in Groups XIX and XXXIX] A shifting register comprises a series of thin magnetic film elements 31-36, Fig. 2a, and associated conductors 22-25, the elements being closely spaced so that the external magnetic field of any one element is able to influence the switching of the next adjacent element. As shown in the plan and sectional views, Fig. 2b and Fig. 2a, the magnetic film elements which may comprise 80% Fe and 20% Ni are embedded in silicon dioxide insulating layers 26-28 which form three planes A, B and C. The conductors are located between the planes and are preferably slit longitudinally as at 29 to facilitate the magnetic coupling between adjacent films. The assembly is produced on a glass substrate 21 by vacuum deposition, electrolytic deposition or chemical precipitation and the slits 29 may be formed by an etching process. As shown in Fig. 3, the conductors are terminated by characteristic impedances Z and are energized by generators GA-GC which produce pulses in the time positions shown in Fig. 4. The pattern of magnetizations produced in the magnetic thin films 01-36 is shown in Figs. 5a-5f (not, shown) each film having its easy axis of magnetization in the longitudinal direction of the register. In Fig. 5a the films 31, 32 (plane A) have respective magnetizations in the easy direction denoting " one " and " zero " registrations respectively, and the remaining films have been switched to the hard direction by current in a conductor loop 22, 24 as determined by the generator pulse pattern at time t 1 . At time position t 2 , Fig. 5b, the conductor loop 22, 23 is energized, and the films 32, 35 (plane B) take up the magnetic state along the easy axis of the adjacent films 31, 34. In the next time position t 3 , Fig. 5c, the films 31, 33 and 34, 36 (planes A and C) are switched to the hard direction by current in the loops 22, 23 and 24, 25. Only loop 24, 25 remains energized at time t 4 , Fig. 5d, and the films 33, 36 (plane C) take up the magnetization states of the adjacent films 32, 35. The loops 23, 24 and 24, 25 are next energized in time position t 5  Fig. 5e, and the films 32 and 35 (plane B) are switched to the hard direction. Finally, the shift cycles is completed by current in loop 23, 24 at time t 6 , Fig. 5f, and at this time the first film takes on the magnetization state of an adjacent input field 39. In a modification, Fig. 6 (not shown), a similar pulse pattern to that of Fig. 4 is obtained by combining polyphase A.C. from generators GA-GC with suitable D.C. bias sources.

Title: Gain control system
IPC: H03G3/30
Filed: 1963-05-27
Abstract: 961,131. Automatic gain control. MOTOROLA Inc. May 27, 1963 [June 20, 1962], No. 21077/63. Headings H3Q and H3T. An automatic gain control circuit for a single sideband suppressed carrier communication receiver is arranged to have a quick rise time but is slow to recover until a predetermined time interval has elapsed, after which recovery is fast. The arrangement is described as applied to a superheterodyne receiver comprising R.F. stages 12, mixer 14 and local oscillator 16, I.F. stages 17, 18, 19 and a second detector 21 feeding audio stages 25. Local oscillations for carrier re-insertion at the detector 21 are generated by oscillator 23. Part of the output of this is also applied to a transistor amplifier 40 of controlled gain, the output of which is further amplified by transistor 54 and applied to a rectifier 62. The output of the rectifier 62 is smoothed by filter network 63, 64 and used to control the gain of the receiver R.F. and I.F. stages 12, 17, 18 respectively. The output of I.F. stage 18 is further applied to an additional amplifier 32, the output of which feeds via transformer 34 into diode rectifiers 36, 37. The output of rectifier 36 is smoothed by capacitor 42 and applied over high-value resistor 41 to the emitter of transistor 40 so as to vary its gain and so the gain of the receiver; the emitter is decoupled to earth for R.F. signals by capacitor 43. This rectifier circuit is of the quickcharge, slow-discharge kind. The output of rectifier 37 is smoothed by short-time-constant circuit 45, 46 and varies the bias on a further transistor 44, the emitter circuit of which is connected in parallel with the capacitor 42 via diode 48 which may be a Zener diode. When the signal decreases, the transistor 44 which is normally non-conductive becomes conductive after a predetermined time interval, due to capacitor 46 discharging; the transistor then forms via diode 48 a low-impedance shunt across capacitor 42 whereby it is discharged and the receiver gain rapidly increases.

Title: Process for the manufacture of esters of dianilidoterephthalic acid
IPC: C09B48/00
Filed: 1960-06-15
Abstract: A dialkyl ester of 2,5-dianilido-terephthalic acid, such as the di-ethyl ester <FORM:0891640/IV (b)/1> is made by dehydrogenating the appropriate di-ester of 3,6-dihydro-2,5-dianilido-terephthalic acid with air, the reaction being carried out in the presence of an aromatic or heterocyclic amine as diluent.  The product may be converted into 2,5-dianilido-terephthalic acid for the synthesis of quinacridone. The esters, required as starting-materials, are obtained by condensing a succinylosuccinic ester with aniline or a substituted aniline.  In Example 1, a mixture of the diethyl ester of succinylo-succinic acid, a large excess of aniline and a very small proportion of aniline hydrochloride is heated at 100 DEG C. for 3 hours.  A strong current of air is then passed through the solution at 100 DEG C. for 12 to 16 hours, and then all the aniline is removed by distillation under reduced pressure.  The dianilido-terephthalic ester, so obtained, is hydrolysed with aqueous-ethanolic sodium hydroxide, and the solution is then filtered.  The filtrate is acidified, and 2,5-dianilidoterephthalic acid is obtained.  In Example 3, p-toluidine is used in place of aniline; and the final product is 2,5-di(p-toluidido-) terephthalic acid.  In Example 4, a solution of the diethyl ester of dianilido-dihydroterephthalic acid in pyridine is treated with air.
