Title: Improvements in or relating to a process for the synthetic preparation of hydrocarbons to obtain fuels having high anti-knock value
IPC: C07C1/24
Filed: 1939-03-08
Abstract: 526,084. Polymerizing olefines. COMPAGNIE FRANCAISE DE RAFFINAGE. March 8, 1939, No. 7527. Convention date, March 9, 1938. [Class 2 (iii)] In a process for the preparation of hydrocarbon fuels having a high anti-knock value, in which gaseous isobutylene is converted into isooctane by a series of reactions comprising hydration by means of sulphuric acid to form tertiary butyl alcohol, dehydration and polymerization of the alcohol to form di-isobutylene, and hydrogenation of the latter, the gases are brought at substantially atmospheric pressure into intimate contact with the sulphuric acid solution,(a) by forcing the gas into the acid through porous plates of material unaffected by the acid, or (b) by passing the acid through an injector device whereby the gas is aspirated into the stream of liquid, or (c) by dispersing the gas in the acid through a rotating distributer having at least one orifice discharging the gas beneath the surface of the liquid. The hydration of the isobutylene and the dehydration and polymerization are carried out in a single operation, the temperature being maintained between 0‹ and 100‹C. Catalysts known to accelerate the polymerization of isobutylenes may be incorporated in the sulphuric acid solution, e.g. boric acid, the sulphate of silver, mercury, titanium, uranium, or cerium, or molybdic, tungstic or vanadic acid. Where the isobutylene is mixed with a butene or butenes, the reaction conditions may be controlled to effect an interpolymerization between the gases, or the butenes may be unaffected and recovered. In the latter case, the recovered butenes may be hydrated to secondary butyl alcohol followed by pyrolytic dehydration to isobutylene, e.g. by means of alumina at a temperature of 500-520‹C. Examples are given.

Title: Improvements in or relating to television apparatus
Inventor: MARTINEZ PEDRO
IPC: H04N5/53
Filed: 1958-03-10
Abstract: 847,703. Television. PYE Ltd. March 10, 1959 [March 10, 1958], No. 7596/58. Class 40(3). [Also in Group XL(c)] Distortion in television signals originating at a remote point is removed prior to feeding such signals to a television transmitter. As shown, the D.C. component is first restored by means of a clamp 6 and the signals fed, with negatively going synchronizing signals, to an amplifier stage V1 the cathode circuit of which includes a rectifier MR1 so biased that it conducts only during the occurrence of the synchronizing signals and effectively connects the decoupling capacitor Cl across cathode resistor R1. The gain of V1 is therefore increased and synchronizing signals of enhanced amplitude are produced in the anode load circuit which consists of a valve V2 shunted by a clipping stage V3. The latter cuts-off at a level determined by RV2 to produce "clean" synchronizing pulses the clipping action being improved by the anode load changing from the low resistance of V3 when conducting to the high resistance of V2. The complete waveform at the anode of V3 is then fed to a similar arrangement V4, V5 and V6 of which the latter operates as a peak white limiter and delivers a "cleaned-up" complete television waveform to a plurality of outputs 5. The circuit may also be employed to insert blanking pulses in a television signal received directly from a camera by operating V3 as a black level clipper to the grid of which the blanking pulses are supplied. For vertical shade correction suitable signals may by inserted in the clamp circuit or applied to the grid of V2.

Title: Means for detecting and measuring the frequency of periodic variations in the speed of moving surfaces
Inventor: CATLING HAROLD
IPC: G01P3/14
Filed: 1955-03-16
Abstract: 781,463. Indicating vibrations. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. March 16, 1956 [March 16, 1955], No. 7634/55. Class 106 (4). Apparatus for measuring the frequency of periodic variations in speed of moving surface 35 comprises an oscillatory system, including a wheel 14 rotated by contact with the surface 35, a fly-wheel 15 also rotatable due to this contact and a number of reeds 17 of known natural frequencies, arranged so that the flywheel 15 tends to keep the speed of rotation of the wheel 14 constant and the reaction between the wheel 14 and the surface 35 upon variation of speed of the surface 35 causes a movement of the system from its equilibrium position, toward which it is urged by its resilient mounting, so that the system oscillates at the frequency of the periodic variations, whereby if the frequency coincides with the natural frequency of one of the reeds 17, that reed will vibrate with substantial amplitude, thus giving an indication of the required frequency. The wheel 14 and flywheel 15 are secured to a shaft 13 rotatable in bearings carried by a flange 12a of a plate 12 and a bracket 18 secured to a shaft 19 which is rotatable in bearings carried by the flange 12a and another flange 12b of the plate 12. A spring 16 secured between the plate 12 and the bracket 18 tends to retain the system in equilibrium position and the shaft 19 carries a platform 25 to which the bank of reeds 17 is secured. An alternative arrangement for mounting the system is described in which the wheel 14 drives the flywheel 15 through gearing. The apparatus may be applied to the periphery of a roller of a speed frame for drafting textile fibres and from the frequency of speed variation thus indicated the effect upon cloth of a given width woven therefrom can be deduced.

Title: Television circuit arrangement
Inventor: RAEDECKE HELMUT
IPC: H03G9/02
Filed: 1970-02-18
Abstract: 1,246,243. Television. FERNSEH G.m.b.H. 18 Feb., 1970 [19 Feb., 1969], No. 7747/70. Heading H4F. A circuit for reducing high frequency noisein television-type signals comprises a device 3 which divides the higher frequency components (passed by high pass or band pass filter 2) into those having small amplitudes below a predetermined (adjustable) value and those having amplitudes above this predetermined value. The small amplitude signals are subtracted 4 from the television signal of full band width after transit line compensation (delay 6) and any necessary amplification 5, and the larger amplitude signals are added 7 to the difference signal thus formed. This invention utilizes the fact that the effect of high frequency noise has most effect on those parts of the picture corresponding to low amplitude high-frequency components, see Specification 685,483, but whereas in this latter Specification the components of high frequency which lie below the predetermined value are lost, in the prseent Specification they are at least partially compensated for by adding-in the signal components in the higher frequency range whose amplitude lies above the predetermined value. The operation of the arrangement and a preferred circuit of device 3 is described with reference to Figs. 2 and 3 (not shown).
