Title: Condensation products of bis(hexamethylene)trianine and organic carboxylic acids and their use as textile auxiliaries
Inventor: BAIRD WILLIAM
IPC: D06M13/405
Filed: 1962-03-11
Abstract: Amides are prepared by reacting one molecular proportion of bis-(hexamethylene) triamine with substantially two molecular proportions of an acylating agent which is a C12-22 aliphatic saturated or unsaturated carboxylic acid or a functional derivative thereof, or a mixture of such compounds, and then reacting the product with substantially one molecular proportion of a second acylating agent which is an acid HOOC(CH2)nCOOH, where n is 2-8, or an anhydride thereof, or a mixture of such compounds.  The products are triamides containing a free carboxylic acid group, and the corresponding ammonium, lithium, sodium, potassium and triethanolamine salts may be prepared.  The amide-forming reactions are preferably carried out in an inert atmosphere, such as in nitrogen; reducing agents such as sodium hypophosphite may be present.  Suitable acids for the reactions are specified.  The products obtained are textile auxiliary agents (see Division D1).ALSO:Textile materials are treated with an aqueous dispersion or solution of the triamides derived from bis (hexamethylene) triamine, one or more C12-22 aliphatic carboxylic acids and one or more acids HOOC (CH2)n COOH where n is 2-8, or a salt of such an amide (see Division C2).  The amides may be employed as lubricating agents for cellulose, animal or synthetic yarns, as softening and antisoiling agents for cellulose fibres, and as soil-resisting finishes for viscose rayon carpeting.

Title: Improvements relating to Cameras.
IPC: G03B7/083
Filed: 1967-03-01
Abstract: 1,173,526. Electrical exposure systems. RICOH K.K. March 1, 1967 [March 5, 1966], No.9596/67. Heading G2A. The exposure time of a camera is determined by the circuit of Fig. 8, which is energized by a battery B, and includes a photo-cell 3 as a lightmeasuring element. Initially, switch S 1  is open, and switch S 2  is held closed by a shutter element, e.g. the leading curtain of a two-curtain shutter. A double-pole switch 8 is in the full-line position. When the release button is pressed, S 1  is closed, and S 2  opens as the leading curtain moves. Capacitor C begins to charge up, and, at a point determined by the light falling on cell 3, activates the circuit so that an electromagnet M is deenergized to release the trailing curtain, and so terminate the exposure. When the photo-cell 3 is not being used to control an exposure, the switch 8 is changed over to the dotted-line position, in which the cell is connected across the battery B to charge it. Means are provided to prevent an exposure being made while the cell is connected in the charging position. Figs.1, 2, 3 (not shown) all illustrate a camera having the photo-cell (3) mounted by the side of the lens (2). In front of the cell is a collimating grid 4 and a filter 5. These are not necessary when the cell is being used to charge the battery, and can be slid out of the way, either laterally or vertically, to allow maximum light to reach the cell. Fig.4 shows a form in which a frame 6 carrying the grid and filter is connected to the double-pole switch 8, so that as the frame is slid to the left, the switch is changed over to the "charging" position. At the same time, it pushes a pivoted lever 9 into a position immediately below a member 10 connected to the shutter release, so preventing the latter from operating. Fig. 6 shows an arrangement used when the frame is slid vertically out of the light path to the photo-cell, to give a warning signal visible in the view-finder 13. A flag 20 bearing the word "NO" is carried on a spring- biased bell-crank lever 18, and is normally not seen in the view-finder. When frame 6 is pushed upwards, lever 18 is pivoted clockwise, so that flag 20 becomes aligned with an opening 15a in a frame-mask 15 and is reflected via a mirror 16 and semi-reflecting mirror 14 into the eyepiece 13. At the same time a pin 21 of lever 18 engages the change-over switch 8.

Title: Improvements in and relating to ventilating fans
IPC: F04D29/38
Filed: 1939-03-28
Abstract: 511,932. Screw fans. BARKER, D. R., and BARKER, W. H. March 28, 1939, No. 9663. [Class 110 (i)] [Also in Group XXXIII] A screw ventilating fan is formed with a flat portion of its driving face toward the trailing edge and with a curved leading section arranged so that the pitch of each blade decreases progressively from the root to the tip. A section of each blade between the trailing edge 4, the root portion and a line 5 joining the outer tip of the trailing edge with the inner point of the leading edge 3 is a flat surface, whilst the remaining portion 2 between the diagonal line 5 and the leading edge 3 is bent over, whereby the pitch decreases from root to tip. The trailing edge is preferably straight, and the leading edge is convexly curved whilst the tip is formed by curve concentric with the shaft. The blade may be made from sheet metal or may have an aerofoil section. The boss is formed with an inner sleeve 7 adapted to be secured to the driving shaft and an outer sleeve 1, the two being connected by segmental ribs 8. The outer sleeve 1 is slotted at 9 to receive the blade root and the latter is bolted to the part 8 through connections 10.
Patent GB-404261-A (GB)
Title: Improvements in or relating to the extraction of solutes from solutions
IPC: B01D11/04
Filed: 1932-04-04
Abstract: <PICT:0404261/IV/1> <PICT:0404261/IV/2> <PICT:0404261/IV/3> <PICT:0404261/IV/4> The extraction of solutes from solutions by means of solvents immiscible therewith and of different density is effected by causing the solution and solvent to flow in counter-current through a column, at least one of the liquids being introduced in finely divided form.  The extraction may be effected in stages, with emulsification between the stages.  The invention is described with reference to the extraction of lactic acid from its aqueous solution by means of ether.  The aqueous acid is fed into a column 1, Fig. 1, from a pipe 43 having a distributor 2 and fills the column, ether being forced in through a spray nozzle 4. The ethereal solution collects in a layer 5 and is drawn off at 6 and, after the separation of the lactic acid, the ether is returned through the nozzle 4.  Two columns 7, 8, may be arranged as shown in Fig. 2, with an emulsifier 9 between.  The emulsifier comprises a perforated plate 12 between two similar rotary plates 13, 14.  Ether is fed into the column 7 through a spray nozzle 10, and lactic acid solution is fed into the column 7 through a distributor 11, the whole apparatus being full of liquid.  In the lower column drops of aqueous acid fall through ether, and in the upper column drops of ether rise through aqueous acid, an aqueous layer 17 forms below the ether inlet, and is drawn off at 15, and an ether extract layer 18 forms at the top of the upper column and is withdrawn at 16.  Several emulsifiers may be arranged in a single column so as to divide it into several sections, as shown in Fig. 3, in which the emulsifiers comprise rotary perforated plates 22 between stationary perforated plates 23. Sleeves 26 may surround the shaft 24 to prevent agitation between the emulsifiers.  The aqueous acid is led in at 20 and the ether at 21. In another modification, Fig. 4, a single column is used with an emulsifier, the aqueous acid entering at 29 and the ether at 31.  The invention may be applied to the extraction of solid solutes, and also to the transfer of a solute from a light to a heavy solvent, for instance for the transfer of lactic acid from ethereal to water solution.

Title: Apparatus for making ice cream confections
Inventor: NELSON CHRISTIAN KENT
IPC: F25D13/06
Filed: 1953-04-09
Abstract: 740,831. Refrigerators. ESKIMO PIE CORPORATION. April 9, 1953, No. 9676/53. Class 29. [Also in Groups V and XXX]  Ice-cream supplied in a partially-frozen state by a pipe 41 is extruded through a die head 42 and is cut into pieces by cutters 43, the pieces falling each on to a carrier plate 17 mounted on an endless chain 14x which guides the plates in a spiral path within a hardening chamber 1 containing refrigerated plates 6 also arranged spirally and supporting the carrier plates. The loaded plates enter an aperture 3 about half way up one side of the chamber and are carried spirally upwards on the frontmost bank of plates 6 and are then transferred to a rearmost spiral bank of refrigerated plates in contact with which they descend to the bottom of the chamber. They are then transferred to the lower end of the frontmost bank up which they are led until they are once more opposite the opening 3 through which they are led for discharge. The chain 14x is led round sprockets 9 supported on shafts 7, 8 lying within the frontmost bank of refrigerated plates and round sprockets 13 supported on shafts 11, 12 within the rearmost bank. One loop of the chain is led through the opening 3 by passing round a sprocket 9x on a shaft 7x outside the chamber. As shown in Figs. 1-3, the plates 17 are hinged at one edge to the chain 14x so that when they pass through opening 3 and are no longer supported by the refrigerated plates 6, they will fall down to discharge the frozen ice-cream pieces on to a shoot and a discharge conveyer 37. The carrier plate may contact a vibrator during this motion to ensure discharge of the pieces. As the plates pass round sprocket 9x they are raised by a cam rail 48 so that they are restored to the horizontal position when they come under the die-head. The plates 6, which comprise four pipes connected in parallel and in contacting side by side relation, are supplied with liquid refrigerant from a header system supplied from a chamber 21 having a float-controlled inlet valve 25 and a suction conduit 34. The mouth of the die head may be heated electrically or by a fluid. As shown in Fig. 17, the plates 17 are not hinged to the chain and are moved to the vertical position for discharge after passing the sprocket 9x by passing over a roller 51 and a sprocket 52, the axle of which is horizontal. The plates are again restored to the horizontal by passing over the roller 51. Reference has been directed by the Comptroller to Specification 726,549.

[Also in Group XXXV] In a cathode-ray tube of the ferro-magnetic metal cone type the cone is permanently magnetized to provide eight equally-spaced magnetic poles around its circumference, the poles being alternately north and south and so positioned that the extensions of imaginary lines in the plane of the picture area perpendicularly bisecting both pairs of opposite sides of the picture area intersect the cone or an extension thereof midway between two adjacent poles of opposite name, and wherein the distribution of magnetic potential of the eight pole field around the tube is given by the equation P=A sin 4#, where A is a constant, 6 being measured about the axis of the tube from a zero line constituted by one of the lines bisecting one of the sides of the picture. This arrangement causes a small deflection of the beam which eliminates or reduces pin-cushion distortion due to the variation of distance from the centre of deflection to the flat or slightly curved screen with angle of scanning deflection. The cone is made of chrome-iron. The Provisional Specification states in addition that the condition P=A sin 46 need not be satisfied exactly and that by suitable design of the coils used to magnetize the envelope a sufficiently good approximation to this ideal condition can be obtained.
