Abstract: 1360353 Thermocouples UNITED KING- DOM ATOMIC ENERGY AUTHORITY 15 Jan 1973 [19 Jan 1972] 2677/72 Heading H1K The wires 6, 6a of a thermocouple are joined together by electrolytically etching and then reversing the polarity of the applied voltage to electrolytically deposit a bead of metal 12. The junction shown in Fig. 3 is one of several spaced along the needle 2 of a disposable hypodermic syringe and forming part of a probe, e.g. for cryosurgery. Each pair of wires 6, 6a of copper and constantan emerges through a hole in the wall of the needle 2, extending through a glass bush 10 and being secured by resin cement 11. The cement 1 and bush 10 are recessed and the needle is cleaned ultrasonically. Using an acidic solution of copper sulphate the exposed ends of the wires 6, 6a are first electrolytically etched and then, by reversing the polarity of the current through the electrolyte, a bead 12 of copper is deposited. The electrolyte is preferably agitated ultrasonically during deposition. Finally the needle 2 is dried, the recesses are filled with cement which is cured and rendered flush with the needle surface, and a spray coat of insulation is applied. Reference is also made to the measurement of the skin temperature of model aircraft for use in wind tunnels.

Title: Improvements in or relating to refuse destructors
IPC: F23J1/00
Filed: 1919-02-07
Abstract: 142,560. Scorer, A. B. Feb. 7, 1919. Refuses-consuming furnaces; grates; doors.-In a refuse-destructor of the kind comprising a number of circular cells provided with rotary grates and doorways for the discharge of clinker, the clinker is broken up and discharged, through the doorways by bars or the like which are inserted through the doorways or through openings adjacent thereto and co-operate with the rotating grates. Figs. 2 and 3 show a destructor having cells a communicating by an opening m. The wall n at the base of the opening is inclined similarly to the plates c surrounding the rotary grates b. Charging-doors o and discharging-doors p are provided for each cell. The grates b are driven from a common shaft d through worm gearing. Adjacent to the clinker-discharge doors p, the plates c are cut away to permit the discharge of clinker down the shoots q. The doors p are preferably fitted with adjustable plates r pivoted to the doors and retained in position by catches s. These plates serve to fill in the gaps in the plates c and retain the refuse on the grate during charging and combustion. To effect the discharge of clinker, bars t<1> are inserted through apertures t, the inner ends of the bars engaging with upstanding projections b<1> on the grates. As the grates rotate, clinker is broken up by the bars and directed through the discharging-openings The projections b<1> on the grates may be dispensed with in cases where the openings tare sufficient for holding the bars in position. An alternative form of clinkering-bar, shown in Fig. 5, comprises plates t<2>, t<3> hinged together at t<4> and mounted on a hinge t<5> outside the discharging- doorway. The hinged bar may be mounted on a carriage so that it may be used for clinkering all the cells. Similarly, the bars t<1> may be mounted on a carriage and used in connexion with the aperture at the side of the discharging-door of each cell. Instead of the opening m between adjacent cells being rectangular as shown in Fig. 3, it may be V-shape, in which case the lower edge of the opening is made horizontal or so as to slope downwardly towards each grate.

Title: Cycle support
IPC: B62H1/02
Filed: 1939-01-28
Abstract: 524,393. Cycle supports. JORGENSEN, H. E. M. Jan. 28, 1939, No. 3047. [Class 136 (i)] A cycle support comprises one or more pivoted supporting-members adapted to be lowered and raised to the operative and inoperative positions by slow rearward and forward rotation respectively of the cycle wheel (preferably the front wheel), after the rider has dismounted, the operating-mechanism being automatically disengaged by centrifugal force during rapid rotation of the wheel when the cycle is being ridden. A plate or carrier 5, Figs. 1 and 2, is clamped to the wheel hub 1 and is provided with an angularly-bent end plate 6 and with a rod 7 forming a pivot for a gravity-controlled arm 8, which comprises a main plate 9 and side members 10 having bent ends 11 pivotally engaging the rod 7. The arm 8 is provided with a rubber stop 12, which abuts against the end plate 6 and the plate 5 respectively in the two extreme positions of the arm. In the forward position, the arm 8 engages an arm 14 pivoted on a stud 15 on a bracket 16, 18 secured to the wheel axle. The lower part of the bracket has an outwardly-bent arm 18a provided with an inclined pivot 19 for a support 20 adapted to be swung downwards to engage the ground in an outwardly slanting position, the movement of the support in either direction being limited by abutments 23, 24 formed by a gap in a flange 17 on the edge of the bracket. The arm 14 is connected by a strap 22 to the support 20, so that when the cycle wheel is reversed, the arm 8 depresses the arm 14, which in turn lowers the support 20. The support 20 is held in its two extreme positions by a tension spring connected by a wire 25 to a fixed pin 26. When the cycle wheel is rotated forwardly again, the arm 14 and support 20 are first pushed towards the inoperative position by the rod 7, the movement being completed by the spring. During riding the arm 8 is swung to the disengaged position 8a by centrifugal action. When the support is in use, the front wheel fork may be prevented from turning by means of a spring-controlled forked plate pivoted to the mudguard and adapted to be turned to engage a frame member. Modifications of detail are described.

Title: Improvements in or relating to cigarette packing machinery
IPC: B65B19/02
Filed: 1926-02-03
Abstract: 275,276. Molins, W. E. Feb. 3, 1926. Stacking-packets. - Relates to packing-machines of the type wherein packets are moved in succession through a vertical stacker from which they are removed for insertion in a carton. According to the invention, a pusher piece or the like is operable at the delivery end of the stacker to displace a batch or series of batches over a horizontal plane. The batches may be delivered alternately on opposite sides of the stacker, and means may be provided to detect and ensure that each batch comprises a predetermined number of packets. As shown, packets of cigarettes, which may have been wrapped by apparatus such as is described in Specifications 165,891, 214,702, and 255,937, are moved in line along a table 1 to a position above a vertically movable platform 2, which thrusts each successive packet into a vertical stacker 3 having sloping portions 5 at the top leading to platforms 4. A pusher 6 is secured to a spindle 12 slidable in a bracket 7 mounted on a diamond-threaded rod. The rod is driven from a continuously rotated shaft 11 through pinions 9, 10, the latter of which has a slipping-clutch mechanism 28. A cam bar 15, Fig. 4, supports the spindle 12 and is so shaped that the pusher moves downwardly until an adjustable horizontal extension 22 rests upon the uppermost packet projecting above the vertical stacker. In use, the vertical pusher 6 moves backwards and forwards above the stacker and removes a predetermined number of packets alternately to the right and left. The rod 8 is threaded so that the maximum speed of the pusher 6 is attained in the middle of each stroke. The packets thus removed may be enclosed in an outer carton placed over a flexible mouthpiece 27, the succeeding batches pushing the foremost into the carton. If the predetermined number of packets is not in position to be moved, the extension 22 is not engaged and consequently the rod 12 moves downwardly until a cam-surface 20 engages a portion 21 of a dog 17, which is thereby moved against the action of a spring 19 into engagement with a tooth 18 and arrests the rotation of the rod 8. If packets continue to be fed by the platform 2, the spindle is eventually raised to allow the action to be resumed. A sliding member corresponding in shape to the outer ends of the diamond threads may be moved axially along the rod 8 so as to limit the number of packets removed from the stacker. In a modification, a series of pushers are mounted on anendless conveyer band continuously or intermittently moved across the end of the stacker, and automatic means may be provided to arrest the conveyer if the predetermined number of packets is not present. In another form, the pusher piece may be constructed so as to be deflected upwardly over a batch on its return stroke.

Abstract: 777,755. Switches, partly electrogamnetic; contact members for switches. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. Feb. 3, 1955 [Feb. 4, 1954], No. 3191/55. Class 38(5)  A pivoted contact member 1, Figs. 3, 4, has a saw-cut 9 in its leading edge to form a straight contact 7 co-operating on either side with the two parts 2a, 2b of the fixed contact member. The parts 2a. 2b are fixed, together and have parallel downward extensions 5a, 5b pivoted at 3 on a conducting mounting 22 to which they are electrically connected by leads 6a, 6b. The repulsion effect produced by the opposite direction of current flow in the contact 7 and the extensions 5a, 5b augments the contact engaging pressure. Additionally, on contact breaking the arc is blown upwards. Outward movement of the fixed contact by the spring 4 is limited by the engagement of lugs 10a, 10b on the contact with fixed projections 8a, 8b. In a modification, Fig. 5, the contact 7 is recessed at 24 to form upper and lower contact zones and the fixed contact parts are slit at 12a. On breaking, the arc is extinguished at the upper zone. The pivot pin 3 co-operates with a slot 13a to permit equalization of the pressure of spring 4 at the four pairs of contact-making surfaces.
