Abstract: 848,813. Television. FERNSEH G.m.b.H. Feb. 22, 1957 [Feb. 23, 1956], No. 6018/57. Drawings to Specification. Class 40(3). A television pick-up tube, such as a vidicon or super-iconoscope, having a non-linear characteristic such that the derived signal is compressed in the highlight range is followed by an amplifier having a complementary characteristic so that the combination has a linear characteristic with a gamma substantially equal to unity. The derived signal is then passed through an aperture corrector stage which by virtue of the linearity of the signal is enabled fully to correct the frequency response since the mean level of the signal is not distorted for components of different frequency. Prior to transmission the signal is applied to a further gamma control stage to introduce a gamma complementary to that of a cathode-ray receiving tube.

Filed: 1929-02-25
Abstract: 334,848. Campbell, W. B. Feb. 25, 1929. Shaping prior to finishing; chrome and mineral tanning; finishing.-In making leather articles, e.g. boots and shoes, the hide after tanning and preparation to receive a surface finish is cut up into parts selected, according to the varying quality of the hide, for the articles to be produced and these parts are then individually finished as required. In order to allow the storage of hides before finishing, two per cent of lactic acid may be added to chrome tanning liquor or the hides may be conditioned after the chrome bath by soaking in a solution containing salt, Glauber's salt, glucose and glycerine. Alum tanned hides may be similarly treated. After treatment the hides may be fat liquored, or left in their tanned condition without fat liquoring and fat liquored prior to cutting up. The reconditioning before cutting up is effected by moistening. A shoe made up from leather parts cut out from the hide and finished afterwards in the manner described comprises a vamp V of scotch grained leather, a quarter Q of black suede formed by pressing the flesh side of the leather, a facing S of plain green leather, a foxing F of green leather with an embossed reptilian design, and a tongue T of plain black grained leather.

Filed: 1916-05-05
Abstract: 106,119. White, H. T., and Doubleday, V. C. May 5, 1916. Valves actmated by fluid under control of auxiliary pilot or relay control valve.-Relates to pneumatic guns especially of the type described in Specification 6503/15, [Class 92 (ii), Ordnance &c.], and of the kind in which a differential valve controls the admission of compressed air to the barrel chamber. The invention comprises an arrangement in which the valve member is of stepped form, being provided with a shoulder, and in which the compressed air leaks around the valve sides to the back of the valve in order to keep the valve closed. As shown in the Figure, the differential valve D, stepped at E, normally closes the passage between the compressed air chamber A and the barrel chamber B, under the influence of the pressure established against its larger end D<2> by the leakage of compressed air around the sides of the valve into the chamber K. When the firing button N is pressed, an auxiliary valve L is depressed to open the ports M, M' thereby lowering the air-pressure in the chamber E, and permitting the compressed air in the chamber A to act upon the shoulder E to open the main valve. The valve L is supported by a resilient pad G abutting against the cover H under the influence of a spring F seated in the upper end of the valve D. The differential action of the valve may be supplemented by mechanical means for retaining it in its seating. The Provisional Specification comprises also a modification in which the leakage to the back of the valve takes place through a tiny orifice or hairchannel in the casing.

Title: An improved alkylation process
IPC: C07C2/60
Filed: 1944-04-14
Abstract: <PICT:0585931/IV/1> In the continuous alkylation of olefins with isoparaffins in presence of an aluminium chloride-hydrocarbon complex, a mixed hydrocarbon feed containing ethylene, propylene or butylene, and isobutane or isopentane, together with undesired components is fed to a scrubber wherein it is scrubbed with a recycle product stream which has become saturated with said undesired components so that only olefin is dissolved therein, the recycled product with dissolved olefin being returned to the reactor with added isobutane or isopentane for contact with the catalyst complex while the undesired components are withdrawn.  The process is particularly applicable to alkylating ethylene with excess of isobutane at 65-200 DEG  F. and 100-1000 lbs./sq. in. with the addition of 1-15 per cent of ethyl or methyl chloride using 3-100 per cent by weight of aluminium chloride.  C2 fractions containing, for example, 10-40 per cent of ethylene and diluents such as methane, ethane and hydrogen may be used. Ethylene and liquid isobutane enter by lines 25, 28 respectively into scrubber 30, and are pumped through aluminium chloride containers 20 or 20a to reactor 1, thence to settler 2, and recycle line 40 back to the scrubber.  The complex catalyst is formed by reaction of the hydrocarbons with the aluminium chloride and product may then be withdrawn through line 12 for recovery of alkylate.  The recycle stream becomes saturated with the inert components of the ethylene feed which pass out from the scrubber at 50 while ethylene dissolves therein and is fed to the reactor. When this becomes full of catalyst, the excess passes to settler 2 and is withdrawn at 8.  The scrubber is maintained at 50-200 DEG , preferably 75-125 DEG  F., and 100-1000, preferably 200-300 lbs./sq. in.  The molar ratio of isobutane to ethylene is 3-100 : 1, and the recycle ratio 1-30 : 1.  Aluminium chloride consumption is from .04-.08 lb. per gallon of alkylate.

IPC: D01B1/40
Filed: 1951-03-22
Abstract: 706,420. Preparing fibres for spinning. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 5,1952 [March 22, 1951], No. 6975/51. Class 120(1) In a machine for shaking flax tow or like material to separate the shives therefrom, the material is advanced along the machine by sets of pins 9 which oscillate or reciprocate in substantially horizontal planes, the pins being arranged at the sides of the machine in rows opposed to one another so as to engage the tow or the like laterally. In the arrangement shown, each set of pins comprises three rows, the gaps between the points of opposed pins being smallest in the lowermost row and being successively wider in the middle and uppermost rows. The pins are oscillated by means of cranks 10 and reciprocating connecting members 11. The throw of the pins, from a position transverse to the direction of feed, is greater in the feeding direction than in the backward direction, and the angular setting of the pins is given a progressive advance towards the discharge end of the machine. In operation, tow supplied to the left-hand end of the machine is propelled with a shaking movement towards the right-hand end, the shive which is shaken out falling between slats 6 arranged as a platform beneath the pins. Instead of oscillating, the pins may be arranged to reciprocate; angular setting of the pins towards the discharge end ensures feed of the tow.
