Patent GB-353873-A (GB)
Title: Improvements in and relating to the treatment of textile materials
IPC: E21D11/10
Filed: 1930-04-23
Abstract: Lecithin is used in dyeing cotton, wool, artificial silk, silk or other textile fibres and fabrics in order to improve the penetration, brilliance and resistance to rubbing of the dyes, and to render the fibres soft and glossy.  The lecithin may be obtained for example from soya beans, lupins, peas, cereal germs and yeast, but residues obtained in the purification of nutrient phosphatides may be employed.  Two extraction processes are described (1) husked soyabeans, after being rolled are extracted with a mixture of benzene and alcohol and the solvent then removed by evaporation.  The bulk of the oil, which is simultaneously extracted, is separated by passing in steam and centrifuging; (2) a benzene extract of soyabeans is freed from solvent and treated with steam, whereby the lecithin and impurities separate as a lower layer.  This is dissolved in trichlorethylene, filtered and evaporated.  The quantity of oil impurity may be further reduced by treating with acetone or acetic ester.  In examples of dyeing processes, materials are dyed in baths containing Chlorantine fast green BL and Indanthrene blue GCD to which lecithin has been added.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of lecithin to any bath for the treatment of fibres and fabrics.  The boiling and bucking of raw cotton with alkaline liquids under pressure, and the cleaning and brightening of fibres are referred to. This subject-matter does not appear in the Specification as accepted.
Patent GB-185462-A (GB)
Title: Improvements in or relating to the condensation of steam or other vapours
IPC: B01D5/00
Filed: 1921-05-03
Abstract: 185,462. Ramsay, D. M. May 3, 1921. Cooling gases by evaporation of cooling-liquids.- In an evaporative, condenser a cooling-liquid is employed which has a smaller surface-tension than water, so that the thickness of the film of liquid on the evaporating surface, which is kept as smooth and clean as possible, is reduced. A suitable liquid is water containing .01 per cent of caustic soda or sodium carbonate. The invention is particularly applicable to condensers of the type described in Specification 5223/15 [Class 32, Distilling &c.], in which the steam is condensed in tubes connecting rotary headers, by the motion of which they are alternately dipped into the cooling-liquid and raised out of it. In the condenser of this type, shown in the Figure, the entrance of the steam into the pipes while they are immersed is prevented by a baffle-plate J<2>. A disc N supporting the tubes and a baffle-plate N<1> in the tank containing the cooling-liquid are so arranged as to prevent circulation of liquid in the tank, so that the liquid at the outlet end is at a lower temperature than that at the inlet end. This effect is enhanced by the slope of the tubes, as shown, which causes the drops of liquid adhering to the tubes and cooled by evaporation to run down the tubes to the outlet portion of the tank.

Patent GB-1350216-A (GB)
Title: Ramp voltage generating circuits
IPC: H03K4/56
Filed: 1971-05-04
Abstract: 1350216 Sawtooth generating circuits IWATSU ELECTRIC CO 4 May 1971 [7 May 1970] 12944/71 Heading H3T In a Miller integrator type ramp generator, e.g. TR6, TR7, C1, a constant current Ic is applied to the input of the integrator and to the collector of a grounded base clamping transistor TR3 having its emitter connected to an input pulse source Ei and to the output of the amplifier. When, in the circuit shown, the input pulse is negative TR3 conducts the constant current which flows thereto via TR4 and TR5 and accordingly the emitter-base diode of TR3 together with D2 and ZD clamps the amplifier output at a given level. When the input pulse is positive, TR3 goes off and the portion It of the constant current Ic flows to the input of the Miller integrator to generate the ramp. Varying the division ratio between TR4 and TR5 of the constant current, varies the slope of the ramp but does not vary the emitter-base current of transistor TR3 when the input is negative and accordingly does not vary the level to which the output is charged during the quiescent period.

Patent GB-589043-A (GB)
Title: Improvements in prepayment meter mechanism
IPC: G07F15/00
Filed: 1944-07-07
Abstract: 589,043. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., TAGG, G. F., and WHITEHEAD, R. K. July 7, 1944, No. 12988. Addition to 572,403. [Class 27] The mechanism of the parent Specification is modified to permit insertion of several coins at once, the motor or other electro-magnetic actuating means, once started by operation of a manual switch, actuating the mechanism repeatedly until all the coins have been credited. As shown, a first coin inserted via chute 3a comes to rest in a pocket 1, the remainder piling on top of the first in the chute 3a as in Specification 572,395. Depression of a push-button 52 rocks a pair of starting contacts 54, 55 for the motor about their common pivot 61, contact 54 thrusting a feeler 56 against the coin in the pocket. This arrests contact 54, and contact 55 closes on it against a spring 62 and is held closed on release of the button by a latch 66 pivoted to contact 54. The motor 49 now commences to drive an actuating shaft 4 a cam 57 on which immediately closes holding contacts 58, 59 for the motor, and a cam 68 thereafter tripping latch 66 to release the starting contacts. Throughout the rotation of the shaft, moreover, a cam 69 rocks a lever 70 to engage contact 54 and ease the coin feeler 56 should the button be held down. As the actuating shaft rotates, a cam 8 releases a centrally pivoted lever 9 connected with the coin pocket allowing a spring 2,to move it rearwardly, the edge of the coin engaging a gauge member 11 and displacing it by an amount dependent on the diameter of the coin. A sliding carriage 12 moving with the gauge 11 is then brought to a position dependent on the denomination of the coin, and the carriage controls the appropriate operation of crediting mechanism in the manner described in Specification 572,389. The cam 69 then causes an apertured sliding base plate 64 under the pocket to release the coin, and cam 8 re-engages lever 9 to return the coin pocket under chute 3a to enable any further coin to fall in. Finally, cam 57 opens the motor contacts 58, 59, but immediately prior to this, cam 68 rocks the lever 50 of the push-button so that the whole operation is repeated if another coin is present. A thermal over-load device 76 is associated with the switch 58, 59. In a modification, the switch associated with the feeler 56 is separate from the manually actuated one. The feeler may as in the above construction, be caused to enter the coin pocket towards the end of the cycle when the previous coin has been discharged and a possible further coin has entered the pocket, the feeler contacts' closing and initiating a further cycle if a further coin is present. Alternatively, the feeler may be arranged to enter the chute above the pocket and operate at an earlier stage to ascertain whether a further coin is waiting. In either case depression of the push-button in the absence of a coin causes the mechanism to operate but without registering credit.

Title: Improved construction of emergency brake mechanism for winding engines
IPC: B66D5/26
Filed: 1924-05-27
Abstract: 227,349. Bell, W. T., and Perry, F. B. May 27, 1924. Overwinding, preventing; emergency power cut-off gear.-The brake engine F is controlled by the fall of a loaded piston in a cataract cylinder G, this cylinder having two adjustable bye-passes 1, 2 the valve 3 of one bye-pass being set and locked for normal use when over-speeding occurs so that the brakes are applied slowly, while the valve 4 of the other bye-pass is normally closed and is opened at the end of the wind so that the piston can fall quickly and the brakes are applied immediately. A governor-actuated arm 55 mounted on the depth-indicator E rocks a shaft B when the speed is excessive and trips and arm 18 so releasing a weight 19 which acts on the piston in the cataract cylinder. The weight 19 is carried by an arm 17 on a shaft C which puts the brake-engine F in action by means of linkage 35, 38, 40, 44 and 45. The valve 4 is opened at the end of the wind by a cam 25 driven from the depth-indicator or winding-drum shaft and acting on a spring-pressed rod 26 connected to the valve. The arm 55 is rocked by the nuts of the depth-indicator at the end of the wind and at intermediate positions when excessive speed causes a centrifugal governor (not shown) to bring notched sleeves into the path of the nuts. The usual hand-operated starting appliances and service and emergency brakes are provided together with automatic devices connected with failure of the power supply and for cutting off the power supply.

Compound or articulated road vehicles.-In sixwheeled vehicles in which the front end of a twowheeled trailer is mounted on a turntable, connected by a transverse axis to the rear end of the tractor, slotted brackets on one part co-operate with pins on the other to limit the tilting movements of the turntable about the axis. The apparatus is intended mainly to prevent overturning or undue tilting of the trailer body or load due to sudden acceleration or retardation when the tractor and trailer make a substantial angle with one another. In the construction shown, the turntable 1, which supports the trailer, is connected by springs 2 to trunnion blocks 3 mounted upon the rear axle of the tractor. The frame 5 of the tractor is independently mounted upon the axle by springs. To limit the tilting movement about the axle, rollers mounted on pins 9 on the turntable move in slots in bracket;; 6, 7 secured to the tractor frame 5. The slots are concentric with the axle and are of a suitable length and width to prevent undue tilting movement of the turntable while allowing some freedom for spring movement and for longitudinal adjustment of the axle to tension the driving chain.

Title: Improvements in sash-windows
IPC: E06B3/44
Filed: 1953-05-11
Abstract: 726,734. Window fastenings. HEDERUS, N. F. R. May 11, 1953, No. 13119/53. Class 44. [Also in Group X] In a sash window having guide grooves 10, Fig. 1, in the vertical sides 3 of the fixed window frame, the sash 5 being such that its external contour lies wholly within the internal contour of the window frame so that the sash is completely detachable without removing any parts of the window frame, the sash carries on each side a vertical latch rod 11 having extensions 12 so that on rotating the rod the extensions may engage the guide groove to clamp the sash in the closed position or engage the groove to allow the sash to slide with respect to the frame or be disengaged from the groove to allow the sash to be removed from the fixed frame. Each rod 11 which is housed in a longitudinal track 16, Fig. 9, along the edge of the sash is operated by a lever 13 which is pivotally mounted on the rod 11 by means of an angularly positioned portion. The lever 13 is guided by the edges of a recess 18, Fig. 5, in a fitting 19 secured to the sash and when in the position shewn in Fig. 5, the rod 11 is so rotated that its extensions 12 lock the sash in the closed position, the sash being pressed against its stopping 20. On moving the lever 13 to the horizontal portion of the recess 18, shewn in dotted lines, the extension 12 press the sash away from stopping 20 and engage grooves 10 to allow sliding movement Further movement of the lever 13 is prevented by a sliding plate 22. On moving the plate 2: upwardly by its knob 23, the lever 13 may be moved to the end of the horizontal portion o recess 18 thus releasing extensions 12 from the grooves 10 and allowing removal of the sash Since the lever 13 is pivoted on the rod 11 by i portion making an angle of about 10 degrees with a plane perpendicular to the latch rod, the movement of lever 13 vertically downwards to the locking position causes an increase of the pressure exerted by the sash towards the window frame. In a modification this effect is enhanced by giving to the left hand edge of recess 18 a wedge-like obliquity. The sash is balanced by cords 27 having their lower ends hooked to the sash and their upper ends wound round the larger area of frusto-conical pulleys 26 rotatably mounted in the top member 1 of the window frame the extreme upper ends of the cords being secured to the pulleys, and cords 28 are secured to the smaller ends of the pulleys, wound around the smaller ends, and have their opposite ends secured to springs 30. In a modification the cords 27, 28 associated with each pulley 26 are formed from a single cord being secured to the pulley where it passes from the pulley part of larger area to that of smaller area.
