Title: Improvements relating to tyres and method of making same
IPC: B29D30/08
Filed: 1936-11-04
Abstract: 474,702. Pneumatic tyres. WING- FOOT CORPORATION. Nov. 4, 1936, No. 30000. Convention date, Jan. 10. [Class 144 (i)] To ensure proper align ment of the cords during the building up of a tyre casing on a drum, the fabric strips are laid on a table having spaced pegs lines, or similar devices so that the cords can be manually positioned and maintained parallel and at the correct angle. The apparatus shown in Fig. 2 comprises a table 20 having two rows of spaced pins 21 between which the cord strips 36 are laid and transferred to the building- drum 26 by rolling the latter along the table. Preferably, a sufficient length is provided to form a double ply so that when the casing is expanded to tyre-form the separation of the cords in the tread-zone allows them to merge, more or less, into a single ply. Fig. 8 shows the assembly of a bead 49 and flipper-strip 51 to the overhanging edge-portion 50 of the double-ply 46. After the parts 51, 50 have been folded-down, the drum is served with a further ply or plies with the cords, indicated by dotted lines 35, Fig. 2; crossing the cords 36. Fig. 5 shows a table marked with lines 37, 38 for ensuring the angular lay of the cords and longitudinal markings 40 . . 43 for different ply-widths. Further to assist the angular laying of the cords, cords 39 of a different colour may be provided at intervals in the fabric strip.

Patent GB-969106-A (GB)
Title: An electrical installation including semi-conductor thyratrons
IPC: H02M7/17
Filed: 1962-08-03
Abstract: 969,106. Converting. SIEMENS-SCHUCKERTWERKE A.G. Aug. 3, 1962 [Aug. 3, 1961; June 22, 1962], No. 30078/62. Heading H2F. [Also in Division H3] Two semi-conductor devices having thyratrons like characteristics are connected in parallel and fired by firing a third semi-conductor thyratron. In Fig. 2 the semi-conductor thyratrons 21-24 connected in parallel to a load 27 are fired by triggering a semi-conductor driver thyratron 20. If one of the parallel thyratrons fires more quickly than the other the supply to driver thyratron 20 would be shortcircuited but to provide sufficient energy to fire the remaining one an inductor is connected in series with the driver thyratron. Where the driver is connected directly to supply terminal 26 a capacitor can be connected in place of the inductor (in parallel with a discharge resistance) to limit the firing current to a narrow pulse. Fig. 3 shows a full-wave rectifier circuit using parallel semi-conductor thyratrons and separate driver thyratrons. The circuit is also usable as an inverter if a D.C. supply is connected in the reverse sense to that indicated to terminals 361 and 362 and the driver thyratrons are reversed. Three-phase rectifier systems are illustrated in Figs. 4 and 5 (not shown). Fig. 1 shows a pulse generator for connection to the driver thyratrons 20 (Fig. 2) and which produces an output pulse having a position in a reference A.C. wave dependent on a control voltage. The control voltage and the reference A.C. are applied between terminals E and A to a transistor which is normally conducting. During the course of the input wave the transistor becomes non-conducting and later on conducting again. When this latter occurs a rapid build-up of current is produced in the transistor due to regeneration between windings 121 and 124 and a current pulse flows to charge capacitor 162. This produces output pulses at terminals 181 and 191 which can be connected to the inputs of different driver thyratrons.

Title: Improvements in or relating to disc ploughs
IPC: A01B5/14
Filed: 1951-12-24
Abstract: 718,122. Reversible disc-ploughs. SIMON, E. G., TURNER, O. J., and FISHER HUMPHRIES & CO., Ltd. March 24, 1953 [Dec. 24, 1951], No. 30178/51. Class 6 (1) A tractor-mounted reversible disc-plough comprises discs 19, 21 secured to arms 16, 20 carried by vertical rotary spindles 14, 15 on the ploughframe 10, the spindles being coupled together for swinging in unison to interchange the sense of the ploughing, and detent means 17, 18 being provided to locate the arms in either of the adjusted positions. The frame comprises a central longitudinal beam 10 connected forwardly to poweroperated draught-links 11, 12 on the tractor. Adjustable depth wheels 13 are mounted at the front of the beam 10 and a stabilizing-fin 25 at the rear end. Parallel arms 22, 23 secured to the spindles are coupled together by a link 24. The beam 16 engages an arcuate guide 17 having latches 18 at its extremities. The interchanging may be manual, but, as shown, is effected by the raising of the plough bodily. A cable 35, connected to a fixed point 37 on the tractor, is attached to an arm 26 freely pivoted on the spindle 14 and attached by a spring 34 to a second arm 32 pivoted at 33 on the beam 10, the arm 32 being linked by a pin and slot connection 31 to an arm 29 rigid with the spindle 14. Tightening of the cable 35, on raising the plough, causes the arm 26 to abut a pin 28 on a plate 27 rigid with the spindle 14,. thereby swinging the tools between the positions shown in Figs. 1 and 2. As the plough is lowered, the spring 34 pulls the arm around the spindle 14 to abut a second pin 28, so that subsequent raising interchanges the discs in the opposite direction.

Title: A process for improving the properties of fibres, filaments and textiles made from cellulose
IPC: D06M15/595
Filed: 1958-09-25
Abstract: Cellulosic fibres, filaments and textiles having improved abrasion resistance, faster drying properties and good water absorption capacity are produced by treating the materials with an aqueous emulsion or organic solution of a mixture of a water-soluble polyester and (1) a polyamide, or (2) an alcohol-soluble mixed polyamide or (3) a N-hydroxyalkyl-, N-alkoxy alkyl-or N- alkthioalkylpolyamide, and then drying at a temperature above 100 DEG C.  Suitable watersoluble polyesters are obtained by the polycondensation of dibasic acids, e.g. succinic, adipic and glutaric acids, with an excess of diols, e.g. glycol. Suitable polyamides are made from caprolactam and hexamethylene diammonium adipate and by the joint condensation of several polyamide generating substances. Specified N-substituted polyamides are N-methoxymethyl polyamides, N-ethoxy methyl polyamides, N-hydroxymethylpolyamides, N-(polyoxyethylenemethyl) polyamides, N-(polyoxyethylene) polyamides and N-alkthiomethyl polyamides.  The aqueous emulsions may be prepared by dissolving the polyamides or derivatives thereof in organic solvents miscible with water, e.g. alcohols, such as methanol, or acids, such as formic acid and acetic acid, and pouring these solutions into water in the presence of the polyesters, which act as emulsifiers. The emulsions may also contain softeners, e.g. sulphonated fats or sulphonated aliphatic alcohols, or antistatic agents.  The adherence of the agents from the emulsified phase to the textiles may be accelerated by the addition of salts such as sodium sulphate, sodium chloride, magnesium sulphate or sodium or potassium acetate or citrate.  Examples refer to the treatment of hosiery made from cuprammonium rayon and of cotton fabrics.

Abstract: 1,011,291. Magazine spindles. MAGNAVOX ELECTRONICS CO. Ltd. July 17, 1964 [Aug. 2, 1963], No. 30765/63. Heading G5R. A magazine spindle for an automatic record player comprises: a central core 3, 4 having three or more radial slots 8, 13; a number of fingers 6 mounted in the slots 13 and forming a primary support for the stack of records 15; a number of pawls 9 mounted in the slots 8 and forming a secondary support for the stack 15; and an operating sleeve 14 surrounding the core, and having slots through which the fingers and pawls can project. In operation, movement of the sleeve 14 upwards causes a portion 19 of it to engage with the cam surface 23 on the pawls, thus forcing the tips 18 outwards to engage with the inside of the hole in the lowest record in the stack 16. Further upward movement of the sleeve now raises the upper part of the core 4 until the tips 18 clear the lowest record and the portion 19 passes over the ends 21 of the pawls forcing the tips outwards to support all but the lowest record. Still further movement of the sleeve forces fingers 6 in allowing the lowest record to drop on to the turntable. Movement of the sleeve 14 is effected by means of a rod 2 passing down through the core and engaging with a sliding cam surface 31, Fig. V, situated below the turntable mounting plate 26.

Title: Overload clutch
IPC: F16D48/06
Filed: 1956-10-09
Abstract: 825,149. Operating clutches. BLISS CO., E. W. Oct. 9, 1956 [Oct. 10, 1955], No. 30769/56. Class 80 (2). In a fluid-pressure engaged friction clutch for a crank-driven press or the like the fluid-pressure loading is varied automatically throughout each cycle to protect the machine against overloading. The clutch 10 comprises friction discs 21 which are engaged by pressure fluid on a piston 19 through a pipe 17, brake discs 23 being simultaneously released. On release of the fluid pressure the clutch discs 21 are freed and the brake discs 23 engaged by springs 27. Pressure fluid for the clutch is supplied from a tank 12 through a high- and low-pressure valve 20 and a stop and start valve 22 to pipe 17 and is also controlled by a valve 26 and escape orifice 36. These valves 20, 22 are opened and the valve 26 closed against spring loading on energization of electromagnets 32, 46, 56 respectively which are controlled by a start-stop and jog-run panel 42, Fig. 3, and drum switches 44, 52, 50, 54, 56 rotated in synchronism with the crankshaft of the press. With the start valve 22 open and the valve 20 also open full pressure from tank 12 is supplied to pipe 17 to engage the clutch and release the brake and this condition applies during the return stroke of the press crankshaft. At the top position of the crankshaft switches 50, 52 de-energize the solenoid 32 to close valve 20. The clutch pressure is then reduced to a lower value controlled by a relief valve 24 for about 150 degrees of rotation of the downstroke. At this position switch 54 operates solenoid 56 to open valve 26 which progressively releases the clutch pressure through the orifice 36 during the remainder of the working stroke when the mechanical advantage of the crankshaft and the danger of overload is greatest. After bottom dead centre valve 26 is closed and valve 20 opened to apply full pressure for the return stroke again. After starting the valve 22 normally remains open unless closed manually to stop the press or automatically on slip arising from overload occurring. To this end electromagnet 46 is controlled by a rotating switch 44 and a time relay 40 in parallel. The switch normally closes before the time relay opens so that solenoid 46 remains energized. If, however, slip occurs in the clutch due to overload the relay 40 opens before the switch 44 closes so that valve 22 is closed and clutch pressure released through outlet 48 to apply the brake and stop the press. An alternative to the valve 26 and orifice 36 to control the clutch pressure release consists in a spring- loaded relief valve the loading of which is modified by a crankshaft operated cam. The valves 20 and 24 could be dispensed with if single pressure loading of the clutch other than at the critical working period would be sufficient for satisfactory operation.
