Title: Method of and apparatus for putting caps on aerosol cans
IPC: B65B7/28
Filed: 1974-09-02
Abstract: 1485626 Capping aerosol cans WEEDON ENG CO Ltd 2 Sept 1974 [6 June 1973] 27102/73 Heading B8T The cap of an aerosol can is placed on the valve stem by the direct use of pneumatic pressure. Initially the frame 20 swings about the axis 22 to present the head 30 to a supply of caps. Suction is applied to the bore 52 to hold the cap in the bore and the frame is then swung back to the position shown in the figure. Meanwhile an indexing mechanism (not shown) places a can 10 in the position shown. Fluid pressure, preferably air, is applied through nozzle 38 to the chamber 36 to drive the piston 34 and the head 30 on to the can. Pneumatic pressure is then applied to the tapping 54 to blow the cap out of the bore 52 and on to the tube 12. The pressures applied to nozzle 38 and to bore 52 are continuously related. The lengths of the bolts 46 and the strength of the springs 44 are adjusted such that when the pressure in the bore 52 reaches the pressure in the can 10, the cylinder 28 is forced upwards over the piston 34 against the force of the springs 44. As flange 42 (attached to cylinder 28) moves upwards it operates the trip switch 60 which releases the pressure applied to the bore 52 and nozzle 38 and instead applies fluid pressure to the nozzle 40 to move the piston 34 upwards together with the head 30. Thereafter the indexing mechanism removes the capped can and a new cycle of operation starts.

Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/03
Filed: 1921-10-12
Abstract: Hydrogen peroxide is distilled from solutions containing or yielding it by bringing the solutions into contact with the highly heated surface of a liquid or a fused salt, the evolved vapours being rapidly condensed.  The liquid or fused salt employed is such that it can be heated, without boiling, to a temperature higher than the boiling-point of the solution to be distilled, and, this having been done, the solution is directed on to the heated surface either as a thin sheet or, preferably, as a spray; a stream of air may be sucked through the liquid to prevent sudden frothing.  The preferred material for the heated surface is sulphuric acid or a fused bisulphate, and as examples of solutions which may be treated by the process, the following are mentioned:-crude solutions of hydrogen peroxide, sodium, potassium, or ammonium persulphate, persulphuric acid, and inorganic peroxides.

Title: Improvements in and relating to processes for the preparation of extracts from the flesh of whales and like marine mammals
IPC: A23L17/20
Filed: 1937-10-06
Abstract: Meat extract is prepared from the flesh of whales and other marine mammals by cutting up the flesh and then heating it at below 100 DEG C. in juice obtained by heating the lean flesh at below 100 DEG  C., the juice finally obtained being clarified by removing suspended materials and oil and then concentrated to the desired consistency. In the example given, lean whale flesh is cut up into flat discs and heated to below 100 DEG  C. in jacketed digesting drums provided with stirring means, 30-40 per cent of the juice being extracted and separated by centrifuging from the flesh from which further juice is expressed in a worm or other press.  The pressed cake may be worked up to meal or guano.  The juice obtained is used to extract fresh pieces of whale flesh at below 100 DEG  C., the juice being continuously removed from the digesting drums through an overflow and may be mixed with the juice expressed in the presses.  The juice is passed through an oil separator which also removes coarse particles suspended in it, any whale oil left being removed in high speed separators.  Albuminous matter may be coagulated and separated by filter presses, centrifuges &c.  The juice is finally concentrated in a vacuum evaporator.ALSO:A meal or guano is obtained by working up the pressed cake obtained by cutting up the flesh of whales and other marine mammals, heating it at below 100 DEG  C. in juice which has been obtained by heating the lean flesh at below 100 DEG  C., separating the juice from the meat, e.g. by centrifuging, and pressing in a worm or other press.

Title: Method of making composite metal sheets
IPC: B23K28/00
Filed: 1959-08-10
Abstract: 876,448. Making composite metal sheets; rolling. OLIN MATHIESON CHEMICAL CORPORATION. Aug. 10, 1959 [Sept. 29, 1958], No. 27267/59. Classes 83 (2) and 83 (4). A method for joining components of a composite structure at high temperatures comprises forming a pack of at least two metallic component sheets, sealing said pack from oxidizing atmospheres by interposing a strip of.an oxygen-reactive material between adjacent sheets adjacent the faying surfaces of said sheets to encircle said faying surfaces, heating said sheets to the working temperature range of said pack, and working said pack at said working temperature range. Two copper or brass sheets 1, 2 are degreased and cleaned and weldpreventing material 3 e.g. a suspension of colloidal graphite or TiO 2  in water, is applied to sheet 1 in a predetermined pattern. The weldpreventing material is then applied at and about the edges of sheet 1 at 4 to completely encircle the applied pattern 3 to which it is connected by strips 5 and 6. A similar strip of reactive material 4 is applied to the edges of the lower surface of sheet 2. Alternatively the sealing strip 4 is of sodium fluoborate, graphite, lamp black or a composition consisting of 85-92% copper, 8-15% phosphorus added to a 2-5% gel of magnesium montmorillonite. After the panels have been superimposed on each other and tack welded at the corners to prevent relative movement they are heated to the welding temperature of 1650‹ F. in an inert or reducing protective atmosphere and then rolled to effect a 65% reduction. The faying surfaces of the component sheets are protected from harmful oxidation during transit from the heating apparatus to the rolls by the sealing strip 4. Finally the rolled blank is trimmed to remove the edges beween which the sealing strip 4 is interposed (Fig. 3) to leave the finished blank 11.

Abstract: 697,903. Lamp caps. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES ETABLISSEMENTS CLAUDE PAZ ET SILVA. Oct. 27, 1949 [Nov. 9, 1948], No. 27592/49. Class 38 (i). [Also in Group XL (a)] An electrical discharge device, particularly a fluorescent lamp, capable of working under A.C. or D.C., comprises a gas-filled elongated cylindrical tube and a cap at each end of the tube, each cap being located within the boundary of an imaginary axial prolongation of the cylindrical wall of the tube and each cap being associated with a thermo-emissive electrode and a cold electrode electrically connected to separate contacts of the associated cap and both located within the tube close to each other near that end of the tube which is provided with said cap, each of said contacts being arranged for cooperation with a particular contact of the sockets into which the caps are intended to be fitted. The caps are either of the type such that when plugged into its corresponding socket the contacts of a cap continue to be connected to the same contacts of the socket irrespective of any turning movement of the tube around its longitudinal axis relative to the socket or of the type such that a cap can only be inserted into its corresponding socket in one particular way and, when so inserted, the tube cannot be rotated about its longitudinal axis relative to the socket. At one end of the fluorescent discharge tube 1, Fig. 1, the thermo-emissive electrode or cathode 2 is connected to the cap contact 8 and the cold electrode or anode 3 to the cap contact 9, and at the other end the thermo-emissive electrode 4 is connected to the contact 10 and the cold electrode 5 to the contact 11. Each cap of the lamp is provided with a small insulating piece 12, Fig. 2, which separates and holds the contacts 8, 9, 10, 11 and which has a projecting portion which can co-operate with a corresponding recess in the socket into which the cap is plugged. With this construction the tube may be withdrawn from the sockets, turned through a halfrevolution about an axis through the centre of the tube and at right angles to the plane of Fig. 1 and the caps inserted in the sockets, thus replacing one cathode by the other and one anode by the other. The same sockets may be used for feeding by D.C. or A.C. For D.C. operation the socket contact corresponding to the contact 8 is connected to the negative conductor and the contact corresponding to the contact 11 to the positive conductor. For A.C. operation one of the conductors is connected to the socket contact corresponding to the contact 8 and the other to the contact corresponding to the contact 10. With A.C. operation the cold electrodes may be employed as starting electrodes, each socket contact connected to the feeding device being joined through a resistance to the contact of the other socket not connected to the feeding device. The Specification as open to inspection under Sect. 91 comprises also the envelope bent in the form of a U or a spiral. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to photographic shutters of the focal plane type
IPC: G03B9/38
Filed: 1922-10-14
Abstract: 187,242. Compagnie AÚrienne Fran- þaise. Oct. 15, 1921, [Convention date]. Shutters with sliding-plates.-A shutter of the focal plane type comprises a screen normally presenting an opaque surface, but adapted, when operated, to present a series of parallel equidistant apertures of equal size, which are displaced for a. distance equal to the distance be tween the slits and are then closed thereby exposing the whole surface in narrow sections. In the form shown in Fig. 3, two parallel sliding- plates R<a>, R<b> having slits a, b in staggered relation are situated immediately in front of and parallel to the sensitive plate, and are held by pivoted stops 4, 4<1> against the action of identical tension springs 1, 1<1>. The shutter is operated by depressing the stop 4 to release the plate R<a>, which then moves to the right under the action of the spring 1, disclosing a series of parallel apertures through the two plates. After a short movement, equal to or less than the width of a slit, a projection 7 on the plate Ra strikes a finger 6<1> secured to the spindle of the stop 4' and lifts this to release the plate R<b>, whereafter the two plates move together at the same speed. Each plate is arrested by a stop (not shown) when it has moved through a distance equal to the spacing of the strips. The exposure is regulated by angular adjustment of the finger 6<1>. In a modification shown in Figs. 5 and 6, a spring controlled cursor 21, slidable between the plates, carries pins 23. 24 engaging slots 17, 18 in the plates so that these are displaced in turn to the right, Fig. 5, and then arrested as the cursor moves downwards under the action of the spring. Exposure in this case is regulated by adjusting the separation of the pins 23, 24. In further modifications, the plates are displaced by similar cams mounted on a common spindle, the exposure being regulated by angularly adjusting one of the cams.
