Title: Improvements in carpet-making machines
IPC: D03D39/02
Filed: 1927-06-23
Abstract: 273,318. Lasek, J. June 24, 1926, [Convention date]. Pile-fabric looms. -A device for forming knots in carpet making comprises a rotatable metal or other ring segment 1 of U-section which receives two warp threads 8, 9. These pass between the fianges of the segment over a thread guide 4 bridging the two walls of the segment. The threads after being laid around the segment pass outside through eyelets 5. By means of rods 2:, which may be controlled by a jacquard for patterning purposes, selected segments are rotated from the position shown in Fig. 1 to that shown in Figs. 3 and 4, whereby loops are formed through which a weft thread 7 forming the pile is passed by a shuttle 6. The segments are then restored to their normal position and the warp threads straightened out, whereby the weft thread is looped around the warp threads and forms double knots as shown in Fig. 6. The warp is held at the rear by yieldable abutments. If one of the warp threads in each pair is merely passed through a jacquard heald, a simple Persian knot is formed.

Title: Improvements in or relating to waveform generators
IPC: H03K5/01
Filed: 1961-05-09
Abstract: 963,597. Transistor waveform generators. E. K. COLE Ltd., and J. A. JACKSON. May 4, 1962 [May 9, 1961], No. 16769/61. Heading H3T. A triangular waveform or square wave generator comprises a complementary pair of transistors T1, T2 with their emitter-collector paths in series connected across two supply lines, two capacitors Cl, C2, one being connected between two electrodes of one transistor and the other capacitor connected between the homologous electrodes of the other transistor, the capacitors having a common terminal, each capacitor in turn being subjected to Miller discharge by its respective transistor to cause the potential of the common terminal to rise and fall in a substantially linear manner. When power is supplied to the circuit as shown in the Figure, capacitors C1, C2 are charged by a current flowing through the base-emitter circuits of transistors T1, T2 such that the potential of point A moves towards earth or the line potential depending upon the unbalance of the circuit. If the potential at A moves towards earth current flows into capacitors C3, C4 such that transistor T4 becomes non-conducting and transistor T3 conducting, current flowing through this latter transistor T3, resistor R2 and the base-emitter circuit of transistor T2 to earth with the result that capacitors C2, C4 are subjected to a linear Miller discharge. When capacitors C2, C4 are fully discharged and capacitors C1, C3 fully charged, terminal A is substantially at earth potential and all the transistors are in a non- conducting state. Current now flows through the base-emitter circuits of transistors T1, T2 and resistors R1, R2. Capacitor C1 now commences to discharge and the potential of the terminal A moves towards that of the negative supply line causing capacitor C4 to charge and transistor T4 to conduct to feed a current through R1 to the base of transistor T1 and causing capacitor C3 to discharge through diode D1, transistor T3 being non-conducting. The capacitors C1, C3 are subjected to a linear Miller discharge and capacitor C2 is charged to the supply line potential, the point A then being substantially at the negative supply line potential and all the transistors non-conducting until the cycle recommences when the potential of A starts to move towards earth. Due to the switching action of transistors T3, T4, a rectangular waveform is developed at B. Variations in the ratio of the fall and rise time of the triangular waveform and hence that of the mark and space of the rectangular waveform may be effected by varying the ratio of the valves of R1, R2. The generator may be free running or triggered from an external source.

Abstract: 1456201 Vehicle address system; conveyer systems GEO W KING Ltd 8 Oct 1973 [6 Oct 1972 (2)] 46323/72 and 17006/73 Headings B7L and B7N In a tow truck conveying system each vehicle is provided with an address pin to control movement of. the vehicles, tow pin from a main floor chain 2 to a subsidiary floor chain at a selected diverging point. The vehicles have castor lead wheels and tow pins which engage in open sided recesses in the chains. Where the main chain 2 runs at a level above that of the subsidiary chain 3 the adjacent sides 15 of the chain channels 13, 14 at the diverging point are cut away whereby when the address pin 18 engages an inclined plate 12, positioned to define the diverging point, the vehicle and hence the tow pin are moved sideways until the latter engages a drive recess in the subsidiary chain. Where the chains are at the same level, the address pin first engages a pneumatic or hydraulic valve whereby a piston-cylinder device 20 is energized to raise inclined plate 12 and ramp 23 to positions where they can be engaged respectively by the address pin.and an arm 11 extending outwards from tow pin 8. As the arm 11 is raised the pin 8 moves out of engagement with the main chain and the forward movement of the pin pivots a pusher arm 25 which moves back behind the pin under the action of a bias spring (not shown). The pin 8 now operates a limit switch 27 whereby a second piston-cylinder device 21 is energized to move the pusher arm to its broken line position during which movement the pin 8 is moved forwards and also sideways by engagement of the address pin 18 with the inclined plate 12 until it drops having passed over ramp 23, into a drive recess in subsidiary chain 4. As the vehicle leaves the diverging point pin 8 engages a second limit switch 28 which restores the devices to-their original condition.

IPC: C22C21/02
Filed: 1926-07-12
Abstract: 255,103. Goldschmidt Akt.-Ges., T. July 10, 1925, [Convention date]. Alloys, obtaining.-Aluminium alloys contain. ing a large proportion of silicon, e.g. 5-15 per cent, and a few per cent of an additional metal adapted to impart a finely granular eutectic structure are obtained by electrolysis of compounds of the desired constituents in a molten fluoride bath. Such alloys have a high elongation factor. The additional metal may be an alkali or alkaline earth metal, a metal of the chromium group, manganese, titanium, vanadium, nickel or cobalt, and may be added in the form of oxide, chloride or other halide. The additional metal may also be drawn from the fluoride flux, or may be contained in the aluminiferous material. In an example, aluminium silicate containing equal proportions of alumina and silica and small amounts of iron oxide and other impurities is after disintegration and separation of organic constituents treated with alkali hydroxide, or carbonate to form alkali aluminate and alkali silicate, the proportions of which are regulated by adjustment of the pressure and temperature which are both slightly above atmospheric. Oxides are precipitated from the solution by introduction of carbon dioxide; the precipitate after drying is added to the molten bath together with material containing the third component.

Abstract: 707,759. Clocks and watches. JUNGHANS AKT.-GES. GEB. July 24, 1951, No. 17560/51. Class 139 A stop-watch or clock for measuring time in fractions of a second is characterized in that a column wheel has associated with it a member which impulses the balance for starting the watch, which arrests it for stopping the watch and which impulses the balance again in order to zeroize the watch, and a further member which, during the zeroing operation, stops the hand indicating fractions of a second upon it reaching the zero position. The column wheel 20a, Fig. 1, is stepped on by a push-button 35 and controls three levers 15, 22 and 39. The lever 15 is normally positioned so that a projection 15b thereof abuts a finger 14 carried by a shaft 11 so that a hand indicating hundredths of a second and also fixed to the shaft 11 is in its zero position. The lever 22 is positioned so that a spring finger 25, 25a carried thereby is away from the balance 27. Upon depression of the button 35 the column wheel 20a is stepped on whereupon the lever 15 is rocked so that its projection 15b leaves the finger 14 and the lever 22 is moved against the pressure of a spring 24 until the spring finger 25 occupies the position 34. In moving, the spring finger impulses the balance 27 to start the watch. Upon another depression of the button 35 the column wheel is stepped on again whereupon the lever 22 is moved by the spring 24 until the finger 25 arrests the balance 27. Upon a third depression of the button 35 the lever 22 is freed to be pulled back to its initial position and in moving again impulses the balance. At the same time the lever 15 is moved back into the path of the finger 14 so that the hand on the shaft 11 is arrested in its zero position. The lever 39 co-operates with heart-shaped cams 41, 42 to zeroize the seconds and minutes hands in the usual way.
