Patent GB-218632-A (GB)
Abstract: 218,632. Kodak, Ltd., (Assignees of Capstaff, J. G.). July 5, 1923, [Convention date]. Development and after treatment.-In a process for producing images by reversal from a sensitive layer containing an image, a portion of the undeveloped sensitive salts is removed, or rendered incapable of development, after the first development, the amount removed or affected being controlled in accordance with the printing- value of the layer for the reversed image. The sensitive layer, for example, containing a silver salt, is exposed in a camera and developed, preferably with a " process " developer. After washing, it is treated with a reversing-bath such an acid permanganate or bichromate bath, and is cleared with a bath containing sodium bisulphite or sulphite. The printing characteristics of the residuum in the layer are then determined, either by inspection, or by trial development, or by submitting test portions of the laver to a hypo bath for different lengths of time and developing them to determine which gives the best image. The layer is then treated in open light with a bath for removing a portion of the residuum in the layer, such as a dilute hypo bath, for a length of time governed by the result of the previous step. After washing, the final image is produced by development, or for example by treatment with a sodium sulphide or an acid stannous chloride bath. Instead of removing a portion of the residuum with a hypo bath, it may be rendered incapable of development by treatment with a dilute solution of potassium iodide, followed by fixing after development. The compositions of various baths suitable for the steps of the process are stated.

Abstract: 1489008 Control of open-end spinning frames TOYODA JIDOSHOKKI SEISAKUSHO KK and DAIWA BOSEKI KK 22 May 1975 22301/75 Heading DID In an open end spinning frame with a plurality of spinning units each comprising a spinning rotor 1 with a common motor 20, fiber supply rollers 6, take-up roller 3 and winding roller 4 with a common drive motor 32, the timing of operation of the various rollers during starting and stopping spinning is based on a measurement of yarn length. The yarn, length measurement is made by a photo sensor 35, 36 associated with a perforated disc 34 on the winding roller or take up roller shafts. Pulses from this sensor are counted by a device having three counters to operate the forward/reverse rotation of winding rollers 4 and take up rollers 3 and the rotation of feed rollers 6. The control is exercised by means of electromagnetic clutches and brakes. An alternative length measurer employs a magnetic sensor and a disc with protruberances of magnetic material. A suitable circuit is described in association with a timing diagram.

Title: New phenanthridine compounds
Inventor: PEAK DOUGLAS ARCHIBALD
Filed: 1950-09-11
Abstract: The invention comprises 2 : 7-diamino-9-phenyl - 10 - ethyl -, n - propyl - and allylphenanthridinium salts, and the manufacture thereof by treating a compound of the general formula <FORM:0697296/IV (b)/1> (wherein X represents a radical convertible to a primary amino group) with an ethyl, n-propyl or allyl ester of a strong acid (e.g. a halide, sulphate or toluenesulphonate) and subsequently converting the radicals X (which may be, for example, nitro, acylamino or carbalkoxyamino groups) into amino groups. Replacement of the anion by a different one may be subsequently effected if desired.  The products are useful as trypanocides. In examples: (1) 2 : 7 - dicarbethoxyamino - 9 - phenylphenanthridine is heated with n-propyl toluene-p-sulphonate in nitrobenzene and the product is hydrolysed with sulphuric acid and treated with ammonium bromide to produce 2 : 7-diamino - 9 - phenyl - 10 - n - propylphenanthridinium bromide; (2) the alkylating agent in (1) is replaced by allyl iodide, and the resulting quaternary iodide is converted to the corresponding methanesulphonate by treatment with silver methanesulphonate prior to the hydrolysis; (3) the alkylating agent in (1) is replaced by diethyl sulphate; (4) 2 : 7-dinitro-9-phenylphenanthridine is heated with ethyl toluene-p-sulphonate and the product is reduced with iron powder in aqueous alcoholic sulphuric acid solution and treated with ammonium bromide to yield 2 : 7-diamino-9-phenyl - 10 - ethylphenanthridinium bromide.

Title: Improvements relating to dry sealing envelopes and the like

Abstract: 500,439. Envelopes &c. PIRIE, APPLETON, & CO., Ltd., and WOLFF, H. Aug. 17, 1937, No. 22569. [Class 146 (ii)] A self-adhesive envelope of the kind including means for preventing premature contact between related adhesive coatings on the sealing flap and rear wall of the envelope respectively, has a plain and uncoated separate slip of paper &c. which is held in position to cover and protect one of the coatings by a pocket or pocket-like parts formed or provided in the envelope structure, the protective slip being readily disengageable from the envelope or movable on the envelope to expose the coating when the' envelope is to be sealed. The envelope shown in Fig. 8 is for postal transmission at the cheap rate, and comprises a front wall 1 having integral therewith a sealing flap 3, side flaps 19, 20, and a bottom flap 2 which forms the back of the envelope. The flap 19 is adhesively attached to the back wall 2 at the lower portion only to leave a pocket 9, but the flap 20 is merely tucked between the front and back walls. An extension 21 of the back wall is folded over the outside face of the back wall and adhesively attached thereto at the lower portion only to leave a pocket 21a. A protective slip of paper 7 is adapted to slide in the pockets to cover the adhesive coating 6 on the back wall. As shown, the slip is cut away at one end to provide a tag 22, the cut-away end facilitating ready removal of the slip 7 when the envelope is to be sealed by superimposing the adhesive coating 5 on the flap 3 on the coating 6 of the back wall. Where the slip 7 is not cut away at one end, ready removal of the slip is facilitated by a thumb recess 10 provided at the upper edge of the back wall, or the top end of the slip 7 may be folded over. In modifications, where the envelope is of the kind which does not permit of inspection of the contents when closed, the pockets are formed at each side by folded portions integral with the front wall, or by separate portions adhesively attached to the back wall. The adhesive coating on the sealing flap may have a protective slip positioned thereover by forming pockets on the side edges of that flap. In the form of envelope shown in Fig. 12, the protective slip 7 is formed with reduced tag-like ends 15 which can be slid into socket-like pockets 16. Instead of removing the protective slip from the envelope, the slip may be slid along the envelope to expose the related coating of adhesive. The pockets in one modification are shallow in depth, and the protective slip comprises a rectangular sheet provided with a slit or slot at each end to provide two tongues one of which slides into the pocket. A single pocket may be arranged at one side of, or across, the envelope.

Abstract: 533,228. Steam injectors. METCALFE, R. D., and METCALFE, J. C. Aug. 5, 1939, No. 22762. [Class 71] In an exhaust steam injector the supply of exhaust steam is controlled by a double beat valve i, j of which the upper valve i is larger in area than the lower and is acted upon by a spring n which closes the valves if the supply of exhaust steam is not adequate to maintain the valves open by acting upon a piston q on the valve stem. The spindle of the valve i, j is at right-angles to the axial line of the injector nozzles. Blow back of live steam admitted through an inlet nozzle b is thus prevented. Water enters the injector between the cones d, e and the steam enters the nozzle system between the cones e, f to pass to a combining nozzle g and delivery nozzle h.

The skimmed milk and cream are pasteurized before or after mixing, the mixture being preferably treated in a flash pasteurizer heated to 165‹ F. and then cooled to about 88‹ F. in a surface cooler. The product is made into Cheddar cheese by the usual process and is finally packed in hermetically sealed metal or other containers for ripening and storing, the containers having a venting valve preventing entry of air but allowing escape of the gases forming from the cheese. The cheese may be wrapped in parchment paper, metal foil, &c. before packing in the container.
