Title: Improvements in and in the manufacture of compound sheets comprising fabricand plastic material
IPC: D06M17/02
Filed: 1943-08-17
Abstract: 612,505. Coated fabrics; compound sheet materials. GILES, E. V. Aug. 17, 1943, No. 13350. [Class 140] Compound sheets of plastic material and fabric are made by building up a plastic sheet on a travelling base from which it can be stripped by alternately spreading plastic material in liquid form in a thin film and solidifying the film by evaporation or polymerization, then applying a film of liquid plastic and rolling on to it while still soft a web of textile fabric, solidifying the last film, and stripping the compound sheet from the base. Before stripping, a surface of plastic material may be built up on the fabric by alternate spreading and solidifying, and, if desired, a second web of fabric may be pressed on the plastic surface layer. Further layers of plastic and fabric may be added to obtain a multi-ply fabric. A cotton fabric may be thus embedded in plastic and a woven or knitted fabric pressed on the plastic surface. The plastic material may be natural or synthetic resin, rubber, or rubber substitute and may be a solution, an emulsion such as latex, or a liquid monomer or low polymer adapted to solidify on polymerization. An example is polyvinyl formal plasticized with diacetin and dissolved in trichlorethylene and methyl alcohol. The fabric reinforcement may be a woven or knitted fabric or a net, and may be elastic or extensible to permit stretching of the plastic sheet. The travelling base may be a polished steel band, or a fabric band with a surface of neoprene which may be smooth, matt, or grained. The products are suitable for upholstery, gaskets, and diaphragms. The apparatus described in Specification 612,504 may be used for forming the plastic sheet, being modified by the provision of bearings for supporting a roll of fabric, guide rolls, and a pressure roller supported in vertically movable bearings for pressing the fabric on to the travelling band. The Provisional Specification describes also the use of a solution of ethyl cellulose and castor oil in xylene and butyl alcohol for making the plastic sheet.

Title: Playing card shuffling device
IPC: A63F1/12
Filed: 1937-05-11
Abstract: 482,850. Shuffling playing cards. WOODS, R. M. May 11, 1937, No. 13400. [Class 132 (ii)] In a card-shuffling device the pack of unshuffled cards is supported on a circular member 27 terminating in arcuate prongs 29 so that upon rotation of the member by the action of a spring 51 the cards are successively dropped into a withdrawing compartment 17. The edges of the prongs may be provided with upstanding ribs. In a contruction wherein the circular member has one prong only, the prong has a central longitudinal groove therein. In use, the pronged member is turned by a knob 25 so as to enter the side of the casing and support the unshuffled pack. The pronged member is retained in this position by the downward pressure of the actuating spring 51 upon a piston rod 41 connected to the pronged member and located over the dead centre. When the knob is given a small reverse rotation, the spring pulls down the piston rod and the prongs are slowly withdrawn under the retardation of a dashpot 43. The speed of rotation of the pronged member, that is, the time of shuffling may be varied by adjusting a venting screw in the dashpot.

Title: Improvements in and relating to fluid pressure brakes
IPC: F16H63/30
Filed: 1942-09-28
Abstract: 561,057. Fluid-pressure brakes. WILSON, W. G. Sept. 28, 1942, No. 13603. [Class 103 (i)] In a fluid-pressure brake system in which the pressure fluid, such as oil, is supplied through a restricted passage for the application of the brake, a cylinder containing a spring-loaded piston is arranged between this passage and the pipe leading to the brake cylinder, whereby the clearance between the brake band or equivalent and the brake drum is rapidly 'taken up and a more progressive rise in the braking pressure is effected. Pressure fluid is supplied to the brake cylinder a from a passage h through a restricted passage h<1>, passage l and a control valve n adapted to connect. the passage r either to an exhaust port s, as shown, or to the passage l. A cylinder m containing a spring- loaded piston o is connected to the passage l so that normally the cylinder contains fluid under pressure and the piston is in an upper position. When the valve n is operated to connect the passages r, l pressure fluid is discharged from the cylinder m to the brake cylinder a so that the clearance between the brake band e and the drum f is rapidly taken up. Pressure fluid supplied through the restricted passage h<1> then returns the piston o and progressively builds up the effective braking pressure in the cylinder a. A number of brakes as used for example in an epicyclic change speed gear may be served by a single cylinder such as m.

Title: Improvements relating to code transmitters for railway signalling systems and the like
IPC: B61L23/16
Filed: 1943-08-21
Abstract: 566,408. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and COLEY, J. P. Aug. 21, 1943, No. 13650. [Class 105] Code current pulses of desired interruption frequency are transmitted to railway track circuits or other railway signalling circuits by a relay included in a circuit tuned to give the desired interruption frequency, a contact of which relay gives successive pulses of uni-directional current to the tuned circuit as the relay armature is oscillated by the oscillating current in the tuned circuit, thereby to maintain the oscillation. In the system shown, the wayside signal SB is controlled by relays HR, DR which are energized from a de-coding transformer DCT in accordance with the coded trackcircuit current in section BT which operates a code-following relay BCFR, by which the decoding transformer is pulsed ; the relay DR is energized only when code of 180 interruptions per minute is received, whereas relay HR is energized when code of either 75 or 180 interruptions per minute is received. Code is transmitted to a rear section AT by a contact 2 of a codetransmitting CTR. This relay CTR is included in a circuit comprising a capacity C and an inductance formed by a secondary winding of a transformer T, part 5 only of which is included if the relay HR is energized and closing its front contact 2, whereas the whole of the winding 5, 4 is included if relay HR is deenergized and closing back contact 2. The code-transmitting relay CTR is maintained in oscillation by its contact 1 applying successive pulses of uni-directional current to the half windings of the transformer primary, portions 6, 7 only of these half windings being traversed by current if the de-coding relay HR is closing its front contact 3, since the remainders are short-circuited by rectifier units R1, R2. Thus, when the de-coding relay HR is energized, the code transmitting relay circuit is tuned to a frequency giving 180 interruptions per minute in the code applied to the rear section AT. If relay HR is de-energized, it closes its back contacts 2, 3, whereby the circuit of the code transmitting relay is tuned to a frequency giving 75 interruptions a minute in the code applied to the rear section. The system shown provides overlap protection since the 75 code is only generated if front contact 3 of the code-following relay BCFR is closed; this requires the train to have passed into the halfsection CT to allow the steady energization of the code-following relay BCFR for half-section BT by a back contact of the code-following relay CCFR for half-section CT steadily closing the circuit from battery RB. No current is supplied to section AT while the.train is in half-section BT since the open front contact 3 of code-following relay BCFR prevents the code-transmission relay CTR being oscillated. The code-transmitting relay may be of the polarized type and the track circuit current may be coded alternating current.

Abstract: 1,038,710. Microprogramme-controlled computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 26, 1965 [April 4, 1964], No. 13981/64. Heading G4A. In a micro-programme controlled computer, the operation code of a macro-instruction is decoded to access a first micro-instruction and the address of a further micro-instruction is obtained from information in the macro-instruction, the further micro-instruction assuming control of the computer after the first micro-instruction or a sub-routine initiated thereby has been executed. Said first micro-instruction causes the address of the further micro-instruction to be calculated by adding the contents of an index location specified by the macro-instruction to an increment field in the macro-instruction. The macro-instruction also includes bits to set control latches (no details). The macro-instruction is called a DIAGNOSE instruction and said further micro-instruction initiates a sequence of micro-instructions which ends when the first micro-instruction of a " fetch next macro-instruction " routine is encountered, or alternatively can end when a particular address is reached in the micro-programme store or after a predetermined number of microinstructions have been executed, a counter being decremented to zero in the latter case. In other macro-instructions, the instruction may specify, operation (decoded to get the first micro-instruction), one operand and the address (as above) of the other operand. The microprogramme read-only store may be as in Specification 985,347 which is referred to.

Title: Improvements relating to the coating of metals
Inventor: FREEMAN DENNIS BRIAN
IPC: C23C18/38
Filed: 1961-04-18
Abstract: A metal which is more electro-negative than copper, e.g. iron, is coated by chemical replacement with copper by treating with an acid solution containing 10 to 40 g./l. of a copper salt such as CuSo4 . 5H2O and 1 to 5 g./l. of an ethylene oxide condensate of a long-chain aliphatic amine, the pH of the solution being 0.3 to 0.8.  The solution may also contain chloride ion as an activator in a concentration of 5 to 40 g./l. as NaCl or the chloride ion may be supplied by using cupric chloride as the copper salt.  The ethylene oxide condensates are derived from primary amines having 12 to 18 carbon atoms and the condensate contains 4 to 12 ethylene oxide units.  The solution may be prepared from a solid composition comprising the copper salt, NaCl, the ethylene oxide condensate and an inert carrier such as sodium sulphate and the necessary acid may be incorporated as a bisulphate or sulphamic acid.  An iron salt such as hydrated ferrous sulphate may also be incorporated when the metal to be coated is iron.

Abstract: 440,990. Sharpening drills. BARTON, E. G. C., Iona, Hempstead Road, Watford, Hertfordshire. May 14, 1935, No. 14165. [Class 60] In a drill-sharpening apparatus the drill is held in a holder 3 reversibly mounted on an arm 8 projecting approximately at rightangles from a member 18 having somewhat the form of a skate with straight and curved base portions 19, 20, the cutting-edge of the drill being sharpened on an abrasive surface 26 when the skate rests on the straight portion 19, and the end faces being backed off by tilting the skate on to its curved portion 20. In the construction shown, the drill is held by set-screws in the holder 3, and its projecting ends are held in vees 9, 10 in the forked end of the arm 8, by a spring 11 attached to one of two lugs 7 formed on plates 5, 6 secured to the holder. A screw 13 passing through the arm 8 bears on one of the plates 5, 6, so that the drill may be angularly adjusted about its axis. When one edge of the drill is sharpened it is removed in the holder 3 from the arm 8 and is replaced after turning it through 180‹ the plates 5, 6 being of opposite hands to allow this. The arm 8 is pivoted on a bracket 15 and secured in adjusted position by a nut 14, and the bracket 15 is attached to the skate 18 at an angle which gives the drill a forward rake. The sharpening is performed by reciprocation of the stone 26 by a hand-grip 28, or alternatively a rotary stone may be employed. The angle to which the skate is tilted when backing off the end faces may be indicated by a pivoted tail piece 22 in conjunction with a scale 25, and the tail-piece may be clamped in adjusted position by a screw 24. For drills needing a rounded corner at the outer end of the cutting-edge the stone 26 may be tilted by a wedge 29, or alternatively, an extension on the skate 18 may engage the wedge to tilt the skate. The forward tilt of the skate may also be produced by an extension upon it which engages a fixed wedge arranged at right-angles to the wedge 29. The drill may be removed for tests during sharpening and replaced in the same position for further sharpening.

Abstract: 1,121,626. Removing gills and entrails from fish. R. G. T. BAADER [trading as FA. NORDISCHER MASCHINENBAU RUD. BAADER]. 29 March, 1967 [10 May, 1966], No. 14232/67 Heading A2U. In removing the gills and entrails from a fish, Figs. 3 and' 4, a pair of transverse cuts are made in its underside, namely: a first cut 30 between the sides 23 of the lower jaw 22, and a second cut 31 which severs the symphysis 28 from the collarbones 27. A third cut 32 is then made, from the cut 31 to the vent 35, to open the belly cavity, and the bridge of flesh 42, between cuts 30 and 31, is then seized by gripping mechanism and dragged out of the fish, together with the gills (20), tongue (36), throat (37), oesophagus (38), stomach (39) and small intestine (40), Fig. 6 (not shown). In apparatus, Fig. 1, for cleaning fish according to the invention, each fish 8 is placed, belly-upwards, in a cradle 4 having a grip 6 with spikes 7, for impaling and holding the lower jaw of the fish. The cradle is secured to an endless, travelling conveyer 1, e.g. an endless chain, which carries the fish under a pair of rotating circular knives 10 and 11, mounted on a raised rotating shaft 9. The diameter of knife 10 is larger than that of knife 11. The shaft 9 is then lowered, so that knife 10 makes cut 31 and knife 11 makes cut 30, and is then raised to await the next fish on the next cradle. The fish is then carried under a rotating circular knife 13, which, co-operating with a spear 12, makes the cut 32 and opens the belly cavity. The fish is then carried to a grip 15 and a pincer arm 16 (both turnable about an axis 14) which seize the bridge 42 and drag it, together with the gills and said entrails, out of the fish, which is then moved past a rotating brush 17, which cleans the belly cavity, and then past a rotating brush 18, which opens the blood vessels above the backbone. The fish is then discharged from the cradle, when it reaches the end of the conveyer.

Abstract: 716,668. Speed governors. SCINTILLA, Ltd. June 5, 1952 [June 5, 1951], No. 14244/52. Class 57 [Also in Group XXXVII] A switch comprises a weight 3 pivoted at 4 on a shaft 1 driven by a motor (not shown) and having holes 3<SP>1</SP> so that when the shaft speeds up, it swings out to the Fig. 1 position. Rotation of weight 3 through 180 degrees depresses a contact spring 6 to separate contacts 10, 11 in the motor circuit and further rotation allows them to reclose, and so on. Thus movement of body 3 causes vibration and periodic opening and closing of the contacts. Contact 11 is adjustable by an eccentric 16 on a spindle 15. The shaft 1 is driven through a 2:1 gearing 19, 20, Fig. 1, or over a variable friction drive comprising a conical drive member 23 engaging a wheel 24 on shaft 1, Fig. 2, member 23 having a slot 23" engaged by a two-armed lever 22 which is manually or mechanically adjustable. The shaft speed can thus be reduced with high motor speeds and increased with low motor speeds.
