Title: Improvements in fastenings
IPC: E05B65/19
Filed: 1938-07-11
Abstract: 516,922. Hook fastenings DAVEY, J., and MACHRAY, G. July 11, 1938, No. 20524. [Class 44] In a hook fastening particularly for motor car bonnets of the kind in which the hook is mounted on an eccentric to provide a tightening action, a series of steps is provided on the hook or on the part engaged thereby, to avoid recessing for precision in fitting, and compensate for stretching of the panel. As shown, the fastening comprises a hook 12 mounted on an eccentric part 6 of an operating spindle with knob 4 mounted in a plate 2 secured to the panel 1. A friction washer 16 under the securing nut 17 acts as a friction clutch allowing lost motion between the hook and part 6. A fixed stop 11 co-operates with a stop 10 on a washer 9 constrained to move with the spindle by a peg 8 thereon to limit rotation of the spindle in one direction, and with a shoulder 15 on the hook to limit movement in the opposite direction. Stop 10-co-operates with a shoulder 14 on the hook to effect positive disengagement. Movement of the hook in the engaging direction is effected frictionally until the hook is arrested by engagement with the part 18 on the chassis, further movement of the spindle then causing the eccentric to produce a tightening effect. The hook has a series of steps 13 disposed successively nearer to the axis of part 6. An alternative arrangement with steps on part 18 is described. Part 18 carries a pad stop 21 serving to locate the panel in correct position.

Title: Improvements in and relating to electronic buffers
IPC: G06F3/00
Filed: 1962-05-30
Abstract: 1,005,779. Matrix buffer stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 30, 1962 [May 30, 1961], No. 20752/62. Heading G4C. The Specification describes buffering arrangements, including two identical magnetic core matrices, for data transfer into a fast store, magnetic tape, from more than one slow inputs, as described punched card readers, although keyboards and paper tape readers are mentioned. The matrices are three-dimensional but may be considered as planes, one binary-coded character being stored in a position defined by row and column co-ordinates. One row of a matrix has the same capacity as a record card, and, if the card is not filled, zeros are entered wherever a character is not punched. A matrix has twenty rows and, while the first ten rows of one matrix are being filled, the other matrix is read out to the magnetic tape. When a card is sensed, a call signal issues which stops a three-stage ring, comprising circuit 14, at the stage corresponding to the card reader from which the signal derived. A multivibrator (not shown) operates to step a row counter 18 one stage and gate the new setting, as decoded in circuit 19, to that address register 15 to 17 associated with the card reader. Thus a row of the matrix currently being written in to, is allotted to a particular record card. In much the same way (Fig. 4, not shown) a position in the row is allotted to each character as it is read, the address being stored in a register allotted to the card reader. The address registers are activated to select the matrix address lines only when a character is ready for entry into the matrix, having been coded in binary from the decimal representation on the card. When a card is past the reading station, an end signal issues. Reception of two call signals without an intervening end signal causes reading to stop. The row counter 18 is divided into two parts, dealing with rows 1-10 and 11-20 respectively. The settings of the counter and the registers 15 to 17 are used to determine when a matrix is to be read out to the magnetic tape. Two triggers (Fig. 5, not shown) control read in to the four parts of the two matrices. Thus when both triggers are off rows 1-10 and 11-20 of one matrix are accessible for read-in. Only when the triggers are in this state is the other matrix read-out to magnetic tape. As soon as the counter has stepped past row 10 and the address registers 15 to 17 hold row numbers higher than 10 (and circuit 37b up), one of the triggers is switched aid rows 1 to 10 of the other matrix are accessible for read in. Specification 733,807 is referred to.

Title: Improvements in spinning of artificial filaments
IPC: D01F6/18
Filed: 1946-07-12
Abstract: <PICT:0614959/IV(a)/1> <PICT:0614959/IV(a)/2> In the production of filaments, yarns and the like from a solution of an acrylonitrile polymer by extrusion into an evaporative atmosphere, the face of the spinneret is immersed in water for a short time at the start of the spinning operation, but the water is withdrawn after extrusion of the spinning solution through the spinneret has begun.  The polymer may be polyacrylonitrile or a copolymer of acrylonitrile in which at least 85 per cent of the polymer molecule is acrylonitrile.  The solvent may be dimethyl formamide.  The spinning solution may be extruded at 100 DEG  C. or above into a heated evaporative atmosphere. The spinneret face may be immersed in water before extrusion begins or shortly after, and it should remain immersed for a short period, e.g. 1-5 seconds, while extrusion continues.  After removal of the body of water from the spinneret, extrusion takes place smoothly without clogging of the holes.  Wetting agents may be added to the water.  The water may be at a temperature of 0-60 DEG C. or more.  As shown in Figs. 1 and 2, spinning solution from pipe 11 is extruded through spinneret 12 into spinning cell 10 which is provided with a heating jacket 20 or an electrical heating device.  A sight opening 23 which may have a hinged door affords access to the spinneret and the interior of the spinning cell.  A cup 24 having a handle 25 and containing water is placed so that the face of the spinneret 12, at the beginning of the spinning operation, is below the level of the water 26.  The spinning solution is at first extruded into and coagulated by the water.  A few seconds after extrusion has started, the cup 24 is moved slowly downwards until the spinneret is clear of the water and is then withdrawn from the cell. Spinning then proceeds smoothly by the evaporative method and the filaments are wound on bobbin 16.  The evaporative medium, which may be air, steam or nitrogen, may be passed in either direction through the cell. Specification 594,999 is referred to.

Title: Improvements in and relating to the production of viscose rayon threads and the like
IPC: D01F2/06
Filed: 1950-08-25
Abstract: A continuous process for the production and treatment of artificial thread comprises the steps of extruding viscose into an aqueous coagulating bath to form a thread, treating the thread with an aqueous solution of dilute sulphuric acid at a temperature not less than 40 DEG  C. and at the same time with an aqueous solution of an oxidizing agent, and then washing and drying.  The sulphuric acid solution preferably contains at least 0.5 per cent of sulphuric acid and it may contain up to 4 per cent.  The solution may also contain sodium sulphate or other salt.  The oxidizing agent may be sodium hypochlorite or sodium chlorite.  The treatment may be carried out while the thread is passing in helical turns along a thread-advancing reel or a pair of thread-advancing rollers.  The freshly spun thread may be stretched between the coagulating bath and the liquid treatment device.  The treated is completely regenerated and is substantially free from coloured impurities, sulphur compounds and elementary sulphur.  In an example, viscose containing 8 per cent of cellulose and 7 per cent of caustic soda and having an ammonium chloride number of 10 is extruded into a coagulating bath containing 10 per cent sulphuric acid, 22 per cent sodium sulphate and 1 per cent zinc sulphate.  The thread obtained is passed in helical turns round a thread-advancing reel which stretches it. It is treated on the reel with a solution of dilute sulphuric acid containing sodium sulphate at 60 DEG  C. and also with a solution of sodium hypochlorite.  Uniform and simultaneous treatment is achieved by placing the jet of hypochlorite solution in the stream of dilute acid solution.  The thread is passed to a second reel upon which it is washed and then to another reel upon which it is dried. Specifications 413,413, 413,414, [both in Group IX], 474,973, 475,023, 652,594 and 661,940 are referred to.
