Title: Improvements in the process of manufacture of products from re-inforced plastic material
IPC: C03C25/143
Filed: 1950-04-05
Abstract: 711,266. Agglutinated fibrous materials. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES . DE ST.-GOBAIN, CHAUNY. & CIREY.April 5. 1950 [April 5. 1949 ; March 25, 1950], No. 8572/50. Drawings to Specification. Class 140 Sheets or bands of plastic materials reinforced with fibres of glass or analogous mineral material. arranged parallel or substantially parallel and wound on a rotating member such as a drum. which serves to attenuate the fibres, are made by applying the plastic material to the fibres, before or during winding on the drum. in the form of an emulsion which is thickened or rendered consistent in such a manner that, in spite of the action of centrifugal force due to rotation of the rotary member, and the loss of , emulsion which may leave the drum during rotation, the quantity of material which is retained on the fibres on the drum is sufficient to obtain in the finished sheet or band between 30 per cent. and 85 per cent. thereof in volume proportion relative to the total volume of the sheet or band. The thickening may be brought about by mixing with the emulsion, e.g. an emulsion of polyvinyl chloride or a co-polymer thereof, a naturally viscous material such as gum arabic alginates, or polyvinyl alcohol, or substances capable of causing a commencement of coagulation, e.g. electrolytes, such as strong acids or bases, salts such as sulphates or chlorides. or sallts of metals with a strongly positive cation, e.g. calcium. barium, strontium, magnesium, zinc or aluminium chloride. Substances, the presence of which in the finished product is objectionable may be removed by washing or destroyed by treatment with a suitable reagent, e.g aluminium sulphate may be caused to react with baryta water. The emulsion and the substance producing the thickening may be applied to the fibres before or during their contact with the drum, or both, as by spraying. or the thickening substance may be applied, before the fibres reach the drum. by means of a device provided with felt saturated therewith, and, where the thickening substance is an electrolyte which is to be destroyed by reaction with a suitable reagent, both these may be applied by successive sizing rods before the fibres reach the drum. A solution of a plastic material capable of adhering to that in the emulsion, e.g. of polyvinyl chloride or after chlorinated polyvinyl chloride when using an emulsion of polyvinyl chloride or a copolymer thereof, may be applied to the fibres or to the drum. or both, prior to application of the emulsion, and the sheet heated thereafter.

Title: Low fat spread
IPC: A23C15/16
Filed: 1974-02-26
Abstract: A process for preparing a spread with low fat content is described which is an emulsion of the water-in-oil type. The spreads prepared by the process described here contain 38-50% by weight of plastic fat, 0.1 to 1.5% by weight of partial glycerides and, as the remainder to 100% by weight, an aqueous phase with a pH of less than 6. The aqueous phase of the prepared spread contains 1-23% by weight, based on the weight of the aqueous phase, of edible soluble milk proteins and edible high molecular weight substances not originating from the milk, and, in this aqueous phase, the weight ratio of soluble milk proteins to high molecular weight substances not originating from milk is in the range of from 15:1 to 1:5. The spread is prepared by dispersing the high molecular weight substances not originating from milk in the water and by dispersing the edible soluble milk proteins either completely or partly in the aqueous phase or completely or partly in the fatty phase and preparing the water-in-oil emulsion from the aqueous phase and the fatty phase. The spreads obtained by this process are stable for long periods of time even at refrigerator temperatures, possess an outstanding taste which resembles that of butter and keep very well, even from a microbiological point of view.

Title: Improved method of treating fibrous material
IPC: D21C3/26
Filed: 1966-02-28
Abstract: Lignin is removed from fibrous material by contact with ClO2 or precursor thereof (e.g. NaClO3 or NaClO2), peracetic, performic or perpropionic acid at a pH of 2.5-4.0, and terminating the reaction before the residual lignin content is reduced below 2% wt. Substantial removal of carbohydrate does not occur.  The reaction may be conducted at 40-70 DEG C.  The ClO2 may be used as a saturated aq. solution. When peracetic acid is used sodium acetate or NH4+ may be present.  Before delignification the raw fibrous material may be subjected to laceration, extraction, mild alkaline pretreatment e.g. with NaOH and a squeezing pretreatment between surfaces moving at different speeds.  This squeezing may be followed by washing.  The delignified material may be contacted with an additional amount of one of the above compounds.  The delignified material can be defibrered e.g. under mild alkaline conditions. The fibrous material may be wood, straw, grass, pulp, bast, flax, pulp board, waste paper or newsprint.

Title: Process for the production of black-blue lacquer dyestuffs
IPC: C09B45/48
Filed: 1939-03-21
Abstract: 526,588. Dyes. I.G. FARBENINDUSTRIE AKT.-GES. March 21, 1939, No. 8963. Convention date, March 31, 1938. [Class 2 (iii)] Black-blue lacquer dyestuffs are manufactured by reacting the complex chromium compound of the azo dyestuff from diazotized 4:6-dinitro-2-amino-1-hydroxybenzene and 2- hydroxynaphthalene-4-sulphonic acid with aliphatic amines containing at least eight carbon atoms, e.g. diisoamylamine, stearylamine, dimethyloctodecylamine, dimethyl-palm-kernelfat-amine, diethyloctodecenylamine, or mixtures thereof. The reaction may be effected in aqueous solution with a salt of the base, e.g. the formate or acetate, or the free dyestuff acid may be reacted with the free bases in an organic solvent, e.g. alcohol. The products are suitable for the preparation of bluish-black cellulose ester or alkyd resin lacquers.

Patent GB-550336-A (GB)
Title: Improvements in or relating to adjustable electric resistors
IPC: H01C1/148
Filed: 1941-07-16
Abstract: 550,336. Variable resistances. WARREN, S. F. (International Resistance Co.). July 16, 1941, No. 8976. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 16, 1942]. [Class 37] An adjustable clamp 9 is tightly fastened in a stationary position between the ends of a resistance element and has resiliently secured to it a contact 21 which engages the resistance element with a uniform pressure regardless of the pressure of the clamp. The resistor comprises a tubular ceramic core 1 on which is wound a resistance wire 2 which is covered by a coating 3 of cement, vitreous enamel, &c. having a narrow longitudinal slot which exposes a strip of the resistance wire. At its ends the resistance wire is connected to fixed terminals. The clamp 9 forms an adjustable intermediate tapping and is formed by a metal band terminating in downwardly extending arms 10, 11. The arm 10 has a right angle projection 12 which bears against the arm 11 and forms a fulcrum when the band is tightened by a screw 13, so that the force tending to tighten the band on the resistor is tangential. A resilient metal strip 20 is spot welded at one end to the band 9 and carries at its other end the contact button 21, which is made of silver or other non-corrosive conducting material. The contact button passes through an oval aperture 22 in the band 9 to engage the resistance wire 2, on which it exerts a radial pressure determined only by the resilience of the strip 20 and independent of the tightness of the band 9 about the resistor. The strip 20 is slightly flattened at its contact-supporting end so that the pressure of the contact on the wire is perpendicular. Notches (not shown) are formed in the band 9 so as to localise deformation when the arms 10 11 are opened for sliding the clamp on to the resistor and thereby preventing disturbance of the relative positions of the strip 20 and band 9.

Patent GB-526594-A (GB)
Title: Improvements in or relating to internal shoe drum brakes
IPC: F16D51/30
Filed: 1939-03-21
Abstract: 526,594. Internal shoe brakes. AUTOMOTIVE PRODUCTS CO., Ltd., PARNELL, F. G., and CHOUINGS, L. C. March 21, 1939, Nos. 9008, 11118 and 15573. [Class 103 (i)] The invention relates to internal shoe drum brakes of the kind in which at least one shoe, e.g., 11, Fig. 1, is arranged to act as a leading shoe in both directions, and in which a single spreading means as 16 mounted between the shoes operates so that at least the one shoe 11 moves circumferentially to engage either of a pair of abutments 38, 17. In one example a fluid pressure cylinder 16 fixed to a back plate 14 forces apart the adjacent shoe 11 and linkage 19 and sliding thrust member 21 which engages the other end of the shoe 11. If a drum 15 is rotating anticlockwise, the shoe 11 is urged against the abutment 38 and the whole of the linkage tends to rotate anticlockwise. No outward movement of a piston 20 acting on the shoe 11 takes place but the other piston 20 pushes on the linkage 19 which moves circumferentially to the shoe 10 and applies a thrust through the sliding member 21 to the remote end of the shoe 11. The reaction of the linkage 19 applies the shoe 10 to the drum. Both shoes now act as leading shoes. If the drum acts in a clockwise direction the shoe 11 is urged by the drum against the thrust member 21. The torque from the shoe is taken by a collar 46 on the abutment 17, the shoe moving relatively to the abutment 38 by means of a slot 37. The linkage 19 is moved outwardly as before but cannot move the thrust member 21 restrained by the braking torque. The linkage 19 operates only on the shoe 10 which is restrained by a stop 58 engaging a notch in the shoe 10 which acts somewhat as a trailing shoe. Adjustment of the shoe is effected by rotating a sleeve 43 causing outward movement of tappets 41, 42. A web 18 of the shoe 10 lies between side plates of the linkage member 19 which presses on the thrust member 21 sliding through a hole 22 in the abutment 17. The shoe 10 has a semi-circular notch 23 to engage a cylindrical surface 24 on the abutment member. The shoe also carries sections 25 mounted on pins 26 passing through the shoe web. The sectors engage tracks 28 on the linkage 19. Fingers 33 on the member 19 limit the rocking motion. The tappet 41 is slotted to receive the end of the shoe 10 and permit it to engage the member 17. Other slots engage the ends of the member 19. In a modification the member 19 is carried on rollers on the shoe 10. In another example, Fig 6, the shoes are operated by fluid pressure cylinder 72 fixed to a back plate 74 with an abutment member 73 and a thrust member 85. Pivoted to a shoe 70 is a bell crank lever 77, 78 connected by a link 81 with another crank 82, 84 pivoted at 83 on the back plate. The action is as before except that the cylinder 72 acts as the top abutment.

Title: Machines for bending sheets and plates of metal
IPC: B21D5/02
Filed: 1949-04-04
Abstract: 659,122. Angular bending. RHODES, C. J. April 4,1949, No. 9149. [Class 83 (iv)] [Also in Group XXIX] In a hydraulic machine for bending metal plates the beam 5 carrying the movable tool 4 is automatically slowed down at selected distances from the bottom of its stroke by means which control the hydraulic system and are adjustable with respect to the beam. The invention is preferably applicable to the machine described in Specification 640,605 in which the beam 5 guided by slides 6, 7 on the frame 1 is actuated by a doubleacting ram 22 through a push-rod 20 carrying a pair of collars 19 operating toggles 12 through links 14, 17. Pressure-fluid is directed to either end of the ram 22 by a control valve 38 which has one position in which it gives a constricted flow for the downward stroke of the beam. For the downward stroke the spindle 37 of the valve 38 is depressed against a spring by foot or hand levers 24, 45 on a shaft 23 connected to the valve through a push-rod 28, Fig. 4, levers 29, 31 interconnected by a latch 30, push-rod 32 and levers 33, 35, Fig. 1, on a shaft 34. The lever 29 is cranked downwards and carries a roller 40 which is moved by a cam 41 on the beam as it descends and shifts the control valve to the position in which the flow of oil is constricted and the rate of descent of the beam thereby reduced before the tool 4 engages the work. As the beam reaches the end of its stroke a cam 39 attached thereto releases the latch 30, allowing the valve to return under the action of the spring to its normal position in which the oil flows to the opposite end of the ram so that the beam is thereby raised. The cam 41 has a rack 43 and is vertically adjustable on the beam in guides 42 by pinion 44 on a shaft 45 which is rotatable by a lever 46 reading against a graduated dial 48 and which may be locked in any position by a spring-loaded plunger 47.

Abstract: 1383814 Holography MATSUSHITA ELECTRIC INDUSTRIAL CO LTD 29 Feb 1972 [1 March 1971 (2) 16 March 1971 (2) 19 Oct 1971] 9338/72 Heading G2J Speckle in images reproduced from holograms is reduced. In one embodiment the image reproduced from a hologram is displayed on a screen after the beam containing the image information has passed a dispersion plate. In a second embodiment a Fourier transform hologram is formed using two reference beams, the object beam passing a diffusion plate before it illuminates the object. The hologram 30 is then illuminated with two reconstructing beams 33, 34 and is rotated back and forth in its plane. This causes relative movement between the two effective speckle images which reduces the effect of the speckle. Alternatively a phase shifter 47 Fig. 12 (not shown) may be inserted into one of the reconstructing beams. In a further embodiment one hologram of a matrix of holograms, formed with diffused light, is illuminated to reconstruct an image superimposed upon which is a speckle pattern reconstructed from another hologram.
