Title: Process for improving fuel oils by treatment with hydrogenating gases
IPC: C10G45/04
Filed: 1937-04-10
Abstract: Fuel oils of poor quality which form deposits on standing are stabilized by treatment with hydrogenating gases at elevated temperatures and pressures and in presence of at least 10 per cent of hydrogenation catalyst so that their hydrogen content is increased by a small amount below 1 per cent by weight. Stationary catalysts are preferably used and comprise destructive hydrogenation catalysts of Groups 5-8 of the Periodic System, particularly sulphides, oxides, or hydroxides of chromium, vanadium, tungsten, molybdenum, iron or cobalt, preferably with the addition of metallic or halogen halides. Tin and zinc salts of organic acids are also specified and the catalysts may be supported on carriers which have been activated. Conditions specified comprise temperatures of 280 to 550 DEG  C., preferably 300-450 DEG  C., a throughput of from 0,3 to 1 kg. per hour per litre catalyst reaction space, and pressures of 100-10000 atoms. The crude fuel oils may be obtained by extracting solid carbonaceous materials with solvents under pressure, by distillation of oils, and by destructive hydrogenation. Bituminous coal is destructively hydrogenated at 460 DEG  C. and 250 atmos. with addition of 0,06 per cent tin in the form of a suitable compound and 0,8 per cent ammonium chloride.  Gasoline is removed from the middle and heavy oil produced, which is then filtered and hydrogenated at temperatures rising from 355 to 390 DEG  C. under 300 atmos. pressure with a throughput of 0,6 kg., of oil per litre of reaction space per hour in a converter charged with tungsten sulphide.  0,42 per cent of hydrogen is taken up by the oil, which is stable when stocked.

Patent GB-376763-A (GB)
Title: Improvements in or relating to radio signalling systems
IPC: H04B1/12
Filed: 1931-04-09
Abstract: 376,763. Wireless signalling. STEEL, W. A., 56, Sparks Street, Ottawa, Canada. April 9, 1931, No. 10546. Convention date, April 9, 1930. [Class 40 (v).] In a radio telegraph receiver the effects of atmospherics &c. are minimized by applying detected currents to a divided circuit comprising a portion sharply tuned to the note frequency and a second portion tuned to a slightly different frequency these circuits feeding valve rectifiers differentially associated with the signal indicator. The output of the audio-frequency amplifier K is passed to the series-connected primaries of two transformers T1, T2, whose low-resistance secondaries are tuned to frequencies f1, f2 differing by about 200 cycles, by condensers C1, K1, C2, K2, and feed two valves VI, V2 connected in push-pull. In the output circuit of these valves is connected differentially a polarized relay E with armature F normally biased against its spacing contact S. When the armature moves to the marking contact M the telephones P are energized with audiofrequency current by the apparatus H which comprises a battery 8 and buzzer-interrupter 14. The required signals on leaving the audioamplifier K are of the frequency f2 and hence the winding E2 of the relay E receives more current than the winding E1 and the armature is operated in accordance with the signals. Undesired signals and atmospherics produce substantially equal effects in the two secondary circuits S1, S2 and coils E1, E2, and do not operate the armature. The armature may be normally biased into the spacing position either mechanically, the signal frequency f2 being produced either by modulation or heterodyning of the carrier, or by the addition of the frequency f1 to the signals which results in the energization of coil E1. Thus marking signals may be sent by modulation of the carrier by a frequency f2 and spacing by a frequency f1, or by the operation of switch L to introduce a frequency f a heterodyne frequency of f<1> may be produced during spacing intervals, the carrier frequency being altered for marking to give a heterodyne frequency of f2. For duplex working two armatures F1, F2, Fig. 2, co-operate with the relay windings, being operated by frequencies f1, f2 respectively, and energizing telephones PI, P2 respectively through interrupters H1, H2 respectively. Specification 147,466, [Class 40 (v), Wireless signalling &c.], is referred to.

July 27, 1916 Butter-cutters; stream-cutting machines.-An apparatus, intended for use in large restaurants, for cutting butter into small slices while enclosed in a chamber and dispensing the slices, consists of an outer rectangular casing 19 with four superposed chambers 15, 14, 16, 17 formed by walls 20, 18, an interlining wall 21 having cross partitions, and two cross partitions 22, 23. Around the back, front and sides of the largest chamber 14 are one or more vertical rectangular tubes 25 of glass, metal, porcelain, &c. protected by casings 28, and having inlets 26 above and outlets 27 beneath leading through the partitions. The hinged lid 12 is raised, and butter in bars of square section is put into the tubes 25, a movable weight being placed on the top of each. The chamber 16 contains a number of plates 31, one for each tube, each having a registering opening 32 and a sliding cutter 36 of glass, metal, &c., which is operated by an external handle 43 and a cord to cut off a slice of butter, the thickness of which is regulated by a plate 46. This plate is caused to recede as the knife is pulled forwards by means of a connexion passing over pulleys 59 and connected to a flange 51 of the plate. The cutter and the plate are returned to their normal positions by springs 44 and 56 respectively. The cut slice of butter falls through a corresponding opening 55 into a drawer 60 from which it can be removed. The butter is kept in a firm condition by a cooling coil 63 or by ice within the chamber.

Title: Improvements in or relating to data processing apparatus
Inventor: JAMES JOHN BERNARD
Filed: 1961-03-23
Abstract: 992,942. Magnetic thin film storage devices. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Feb. 14, 1962 [March 23, 1961], No. 10659/61. Heading H3B. In magnetic thin film storage apparatus a word magnetic field is applied perpendicular to the easy axis of the film at each of a number of successive periods at which data is to be stored, and a digit magnetic field parallel to the easy axis is changed only when the digit to be stored differs from the digit stored in the preceding period. Cycle control device 10 drives generators 7, 8 to define the start of a reading and a writing phase in each cycle. Driver 7 provides a pulse at each timing pulse. Alternate timing pulses are applied to driver 8 through gate 11 which is set in one state or another depending on the binary digit to be entered. Driver 8 produces a continuous current so long as gate 11 is in one state. If the digit changes gate 11 switches to its opposite state thus switching a bi-stable trigger unit associated with driver 8, which then produces a different continuous current, or zero current. As currents continue to flow in conductor 4 during the reading period disturbances due to switching off the digit drive current are eliminated. A matrix of elements using this principle is described, in which conductors 4 and 5 are combined as a single conductor, and reading amplifiers are coupled to the conductors through transformers.
