Patent GB-806886-A (GB)
Title: Method of producing large-surface mouldings from fibrous material and synthetic resin, mainly with the application of low pressures
Inventor: LANG KURT
IPC: B29C70/86
Filed: 1955-09-09
Abstract: Layers of a fibrous fleece of the consistency delivered from a carding machine are spread with layers of synthetic resins in powder form and superimposed to form laminated material with the resin between the fleece layers, whereupon the laminated material is placed in a heated press mould and shaped and compressed to form a finished moulding.  Suitable resins are cresylic, phenolic and mixture of the two, epoxy, polyester and rubber-modified synthetic resins.  For thicker mouldings the laminated material is precompressed between plates or rollers and stacked to form layers before being moulded.  A nap of e.g. cotton waste may be wound on a roller while resin powder is sprinkled on it, stripped by an axial cut, precompressed between rollers and blanks cut from it of the size required for the moulding. For local thickening of the moulded product additional fibrous material is added in appropriate places.  Screws or similar elements, or other reinforcement parts, e.g. of wood or plastic, may be located between the layers before moulding.

Title: Improvements in the manufacture of beta naphthol 2:3:6 and 2:6:8 disulphonic acids
IPC: C07C309/43
Filed: 1922-09-27
Abstract: 2-Naphthol-6 : 8-disulphonic acid is isolated from solutions containing it, for example from the crude sulphonation product of b -naphthol, as its sparingly soluble dipotassium salt by addition p of a potassium salt; in the case of the sulphonation mixture, lime is also added to neutralize free acid, the calcium sulphate filtered off, and the filtrate concentrated and cooled. 2-Naphthol-3 : 6-disulphonic acid is isolated from solutions containing potassium salts thereof by boiling with lime, whereby a basic calcium-potassium salt is formed and separates.  An example is given in which b -naphthol is sulphonated at 60 DEG  C. for 48-60 hours, and the 6 : 8-disulphonic acid separated as the dipotassium salt and the 3 : 6-disulphonic acid as the basic calcium-potassium salt; the latter is then converted to the sodium salt by treating with sulphuric acid to precipitate the calcium as sulphate, and salting out.

[Class 83 (iv)] Tilting jaws 22 grip and raise a billet on its edge 21, Fig. 5, after which it can be traversed bodily sideways. The jaws are closed on the billet by a crank 5, Fig. 3, operating toggles 3 and 4. The jaws 22 comprise one side of a jointed parallelogram the other sides being 9 and part of the lever 8, right of the point 10 and part of the link 11 ; the other parts of 8 (left) and 11 (downwards) forming a smaller parallelogram with 13 and 18 the point 15 being fixed on the carriage. The height of the tongs can be varied by motor 25 actuating crank shaft 23 and link to point 17 whereby the parallelogram 13 &c., pivots about the fixed point 15 so that the parallelogram 9, 8, &c., is also raised or lowered and hence the jaws 22 are raised or lowered. The link 13 is resilient to avoid breakage. The tongs are inclined, e.g. at a or a<1>. Fig. 2, by the motor 20 operating a worm gear 19 which rotates the lever 11 about the fixed point 15 so that the angle of the parallelogram 9, 8, &c., varies so tilting the jaws 22. The motor 29 operating through gearing 30 and shaft 36 operates the crank 5, Fig. 3 to open or close the jaws on the work. The carriage 16 is traversed on rails 26 by motor 27 to move the work transversely. Fig. 2 shows the jaw movement from the position a or the position a<1>, to central position c. The jaws may be in the form of rollers, Fig. 4. In a modified mechanism a roller and guide on one limb of a parallelogram, Fig. 7, (not shown), keeps the tongs head at the same height during swinging.

Title: Improvements in rotary pumps and fans and impellers therefor
IPC: F04D1/02
Filed: 1926-10-19
Abstract: 285,531. Rees, E. S. G. Oct. 19, 1926. Casings; impeller blades; helico-centrifugal apparatus.-The blades of a rotary pump or fan have spirally disposed blades with a thickened edge which curves back from the boss against the direction of rotation and the blades are of increasing depth from the front for a. distance, then uniform, and the rear part is again of increasing depth whilst the pitch diminishes over this rear part. For a pump a casing is used with a large inlet chamber, and at the delivery end there is a ring of deflector blades. Means for supplying air at the region of lowest pressure is provided for preventing cavitation. The impeller A, Fig. 2, has spirally wound blades with curving backwardly and the depth of the blades increases toward the middle and is constant toward the discharge A<3>, the edge A<1> being thickened. It is mounted in a casing with a large capacity inlet E, with deflector delivery blades F,. and with. an expanding delivery chamber G formed between the outer part I and conical boss H. A bye-pass J connects the inlet with the hollow cone whereby air passed between the fired and rotary blades A, sealing ring K, is used to cover the gap between the two sets of blades. In a modification, the outer edge of the blades sweep a cylindrical surface and the boss has a configuration which gives the required variation in depth of blade. The axial delivery chamber may be replaced by one of volute form, the stream being discharged outwardly. Parts A only of the blades may be cast together with intermediate blades A<4>, Fig. 5<a>, with the boss B, Fig. 5, the remaining parts being cast on a ring A<0> which is secured to the boss. The bulbous edge may be hollow, the duct a<0>, Fig. 6, therein communicating through the hollow boss with a duct D‹ on the driving shaft, this duct having a valve which opens at a given pressure to admit air.

Abstract: 864,174. Electric digital-data-storage apparatus. SYLVANIA ELECTRIC PRODUCTS Inc. Aug. 18, 1958 [Aug. 23, 1957], No. 26554/58. Class 106 (1). A drive circuit for selectively applying a positive or negative current signal to any one of a plurality of output circuits comprises transformers each having first and second primary windings and a secondary winding, the first primary windings being connected as cross points in a co-ordinate array of conductors. The circuit described is employed for selecting the X or Y lines of a 64 x 64 magnetic core matrix store. Each transformer has a read winding 16, a write winding, and an output winding connected to deliver a half read or write pulse to a co-ordinate line of the store. For the purposes of reading, windings 16 are connected with rectifiers in the 8 X 8 array shown. Triode driving circuits 19 feed the row conductors as triggered from one of the eight outputs from a selector matrix 21 gated from a lead 23 over AND gates 22. The matrix 21 is driven from a part 20 of an address register. Driving circuits 24 feed the column conductors as determined through AND gates 26 by the selector matrix 25 driven by a further part of the address register (not shown). For writing, the write windings on the transformers are connected into a second 8 x 8 array (not shown) driven by further parts of the address register and further AND gates and driving circuits. The store may be three-dimensional, the X and Y lines in different planes being connected together.

[Class 97 (i)] [See also Group XXV] Relates to spectacle frame hinge joints of the kind described in Specification 236,271, [Class 97 (i)], in which the butts are offset relatively to the plates or sunk further into one plate than the other, so that the thickness of the butts does not lie between the surfaces to be folded together. The Figures show joints for connecting a side 2 to an eyeframe 1. In Figs. 1 and 2 the member secured to the side is deeply stepped to bring the bottom of the plate 3 carrying the butt 4 to the plane of the plate 5 carrying the butts 6. The plate 5 is made in two separate pieces, each having a butt, and the butt 4 extends through the space between them. The plate 3 may be sloped as well as stepped, the sloped portion compensating for the thickness of the plate 5 so that the parts 1, 2 come into contact with each other when the joint is closed. The ends of the butts 4, and the base portion of the plate 5 below the butt 6, may be formed as bevel stops to limit the opening of the hinge. In Fig. 9 the plate 3 is slotted to accommodate the butt 6 and is stepped to allow for the thickness of the plate 5.
