Title: Improvements in or relating to hydraulic couplings, particularly for use with automatic change speed gears
IPC: F16H47/08
Filed: 1952-10-24
Abstract: 767,193. Hydraulic couplings. SELFCHANGING GEARS, Ltd., and MILLER, A. A. Oct. 8, 1953 [Oct. 24, 1952], No. 26753/52. Class 69 (2). [Also in Group XXIV] The impeller 9 and turbine 10 of a hydrodynamic fluid coupling are forced axially apart by centrifugal pressure of liquid in the working circuit to engage a friction clutch 16 which directly and mechanically connects the impeller and turbine for non-slip drive above a predetermined speed. The impeller 9 is fast to an input drum 3 and the turbine 10 drives a automatic change-speed gear similar to that in Specification 740,692 (see Group XXIV), and is mechanically by-passed in all ratios except the lowest. The input drum 3 forms a sealed enclosure to which working and lubricating liquid, viz. oil, is pumped through a duct 31 in a stationary block 32; axial and radial shaftducts 35, 36, axial clearance 37, and radial ducts 38 in a stationary sleeve 21. After lubricating and passing radially outwards through the gears, the oil passes through an outermost duct 24 to a space at the right of the fluid-coupling, where it collects centrifugally to be fed through a fixed scoop tube 25 and ducts 26, 28 to the inner periphery of the fluid-coupling, whence it passes centrifugally through radial ducts 29 in one vane into the working space. Overflow from the inner periphery 28 passes inwardly through a radial duct 39 in the fixed sleeve 21, axial clearance 40, radial duct 41, housing-space 42 and radial duct 43 to the sump.

Title: A process of and an apparatus for low temperature gas separation
IPC: F25J3/08
Filed: 1959-08-06
Abstract: 904,007. Cold separation of gas mixtures. LINDES EISEMASCHINEN A.G. GES FUR. Aug. 6, 1959 [Aug. 6, 1958; Aug. 11, 1958], No. 26914/59. Class 8(2). In a gas mixture e.g., deterium and hydrogen separating process wherein a refrigerant e.g., pure hydrogen is supplied as reflux to the head of the column 17, the refrigerant hydrogen is cooled in heat exchangers 3, 4 and is freed of impurities by passage through a pair of alternating adsorbers 7, 8 located upstream of alternating heat exchangers 12, 13 having paths 14, 15 in which the refrigerant is cooled prior to expansion in a valve 16 and entry into a condensing chamber 19 beneath the column 17 followed by further expansion at a valve 20 and entry into the head of column 17. Product deterium hydride-rich liquid hydrogen containing deterium leaves the base of column 17 whilst pure hydrogen gas is discharged through a duct 22 to a compressor 1 delivering at 165 atoms pressure into a cooling and purifying system which includes an exchanger 11. Feed hydrogen and deterium hydride mixture at 6 atoms pressure is supplied from an industrial gas plant 31 through a duct 32 and is cooled in one or other of regenerators 12, 13 not being cooled by a portion of returning hydrogen in a duct 35, expanded at a valve 33 and fed at 34 into the column 17. Return hydrogen leaving the regenerators 12, 13 also serves to cool exchanger 4 before being returned to the industrial gas plant 31. Extra cold is provided by nitrogen from a compressor 23 being expanded from 200 to 1 atms. pressure at a valve 25 and after traversing exchangers 3, 28, 11 and a separator 30 is returned to the compressor 23. Column 17 is enclosed in a gas tight slag-wool packed metal casing charged with helium, hydrogen or nitrogen surrounded by a concentric casing containing the regenerators and charged with slag wool and an inert gas e.g. nitrogen.
Patent GB-411090-A (GB)
Title: Improvements in slide rule calculators
IPC: G06G1/14
Filed: 1932-09-29
Abstract: 411,090. Slide - rules. BOARDMAN, H., Carlton House, Radcliffe New Road, Whitefield, Lancashire. Sept. 29, 1932, No. 26996. [Class 106 (i).] A " deviation " scale is applied to the stock, slide or curser of a slide rule and is used in conjunction with other scales on the rule to perform calculations which would otherwise require extended or additional scales. In the example shown in Fig. 1, a log-log "deviation" scale W1 is placed on the stock and is read in conjunction with an index Y1 on the slide so that log-log settings can be made which would otherwise require the extension of the log-log scales E, F in the direction of unity by additional scale lengths G, H. To set for log10log101.04 the index Y1 on the slide is brought opposite the 4 mark on the scale W1 and the cursor line M is set to 4 on the scale C. The cursor line M is then in a position corresponding to log10log101.04 and, moreover, the significant figures of log 1.04 can be read from the D scale. The log-log " deviation " scale is thus constructed by determining the differences between the logs and log-logs of numbers, having regard to the relative positions of the A, B, C and D scales. Fig. 7 shows a rule in which a " deviation scale W5 replaces log-sin scales P, Q, the " deviation " scale being graduated in accordance with the formula log #- log-sin #. In this example, to determine sin 30‹, the slide is moved to bring 30 on W5 into conjunction with 3 on D, whereupon C10 is against À5=sin 30‹ on D. The first portion of the B scale may be used as a " deviation " scale W3, Fig. 3, in certain cases. The Specification describes also the construction of "deviation" scales relating to tangents and inverse and hyperbolic sines and tangents.

An intermediate-frequency amplifier for a television receiver comprises a pentode V 1  coupled by a pair of coupled tuned circuits T 1  to a triode cathode-follower V 2 , the cathode load of which is a transformer T 2 ; the secondary of this comprises a third tuned circuit. The valves V 1 , V 2  may be included in the same envelope. According to the invention, a "trap" circuit, L 1 , C 3 , tuned to the sound intermediate frequency, is included in the anode circuit of the cathodefollower V 2 . This also causes an increase in response at the high-frequency end of the video pass-band, due to positive feedback through the anode-grid capacity of the valve V 2 : the passband response is restored by means of a damping resistance R 3  across the grid circuit. The Provisional specification also refers to an arrangement in which a "trap" circuit is inserted in the lead to the screen-grid of a pentode amplifier.
