Title: Improvements relating to Machines for Filling Cartons and other Receptacles with Powdered or like Material.
Inventor: SMITH ARTHUR
IPC: B65B57/06
Filed: 1917-12-11
Abstract: 119,159. Smith, A., and Southall, C. Dec. 11, 1917. Packing and filling granular and like materials into receptacles.-In machines comprising a reciprocating plunger b for raising a receptacle-holder a up to a filling-nozzle provided with a screw or the like for feeding the material, a device of the following character is provided for arresting the plunger and thereby preventing material from being fed, when a receptacle is missing from the holder. A spring- urged feeler e mounted in the plunger is formed with a nose g which projects the same distance as a collar i on the plunger, the nose and the collar co-operating with a spring- urged catch h. If a receptacle is present, the feeler is depressed and the catch is held back during the raising of the plunger, by the nose and the collar. If a receptacle is missing, the catch swings over the collar and the plunger is arrested before the clutch in connexion with the feed-screw is operated. To enable the receptacle to hold down the feeler, the receptacle-holder may be provided with a spring blade for engaging the receptacle. As applied to machines in which receptacle-holders are mounted in a rotary table and are brought in succession over the plunger, the feeler is depressed by contact with a receptacle during the initial part of the stroke of the plunger.

Abstract: 139,998. Restucci, G. July 24, 1919. Treatment, special systems of. - Apparatus is provided for separating air from sea-water, mixing it with air collected near the surface of the sea, and supplying it under pressure to closed chambers within which patients are placed for medical treatment. Sea-water drawn through a pipe 3 by a pump 1 is sprayed through a perforated cone D into a perforated conical chamber C mounted on a perforated partition B in a separating-chamber A. Water passing through the partition B is further broken up by blades F rotating within a gauze or netting casing H. The separated air, together with air drawn through a pipe 5 from a point near the surface of the sea, is forced by a pump 4 to reservoirs 7 fitted with pressure gauges, safety-valves, level indicators, and valves 8 for the discharge of water carried over with the air. Air from the reservoirs 7 is supplied, after warming or cooling if necessary, to closed treatment chambers 13 fitted with discharge valves 15 adapted to maintain a constant pressure. The discharged air is drawn through a pipe 14 by a pump 16 and finally discharged into the sea. In a modified form of separator, Fig. 2, a vessel N in communication with an air dome O receives seawater through a rose on a pipe 18, and air from above sea-level through a pipe 5 fitted with a perforated cone 22, which discharges below the level of the water in the chamber. Air separated from the water, together with that supplied through the pipe 5, collects in the dome 0 and is drawn off through a pipe 21. The chamber N is fitted with a water-gauge 19 and a water-discharge pipe 20. A coil 23 for regulating the temperature of the air may also be fitted.

Title: Improvements in high expansion ratio condensation nuclei apparatus
Inventor: SKALA GEORGE FRANK
IPC: G01N15/06
Filed: 1961-05-23
Abstract: 913,515. Turbidometers. GENERAL ELECTRIC CO. May 23, 1961, No. 18554/61. Class 97 (3). [Also in Groups XXIX and XL (b)] In a condensation nuclei detector of the type in which gaseous samples are periodically introduced into a chamber in which they are expanded and the concentration of nuclei is indicated by the intensity of radiation scattered by the fog produced on expansion, the samples are drawn alternately from a source of nucleibearing and a source of nuclei-free gas and pressure-regulating means controlled in response to data obtained from the expansions of the nuclei-free samples serve to continuously adjust for variations of ambient pressure and temperature to provide a pressure reduction within the chamber of a magnitude just less than that necessary to produce spontaneous condensation (i.e. condensation during the expansions of the nuclei-free samples). Gas samples are introduced into a chamber 1 and expanded therein by coupled rotary valves A and B and a vacuum pump 15, successive samples being introduced alternately from conduits 2 and 3. Conduit 2 has connected in it a filter 9 and a humidifier 10, whereas conduit 3 has connected only a humidifier 11, so that the conduits supply respectively nuclei-free and nuclei-bearing gas at a relative humidity of 100%. Upon the cooling of each sample by adiabatic expansion condensation forms on any nuclei present and may form in the nuclei-free samples by spontaneous condensation. The intensity of light from a source 17 scattered by the condensation is detected by a photo-cell or photo-multiplier 18 whose output is supplied alternately to peak reading voltmeters 25 and 26. The output of voltmeter 25 may be connected to a meter or recorder to indicate the concentration of nuclei in the nuclei-bearing samples whilst that of voltmeter 26 serves, together with the voltage from a potentiometer 30, to control a pressureregulating valve 14 (see Group XXIX) which determines the pressure to which the samples are expanded so as to just prevent the occurrence of spontaneous condensation.

Abstract: 1466562 Inflatable life belts N D GEARY 3 April 1974 [17 April 1973] 18573/73 Heading B7U [Also in Division E2] An inflatable life belt comprises a tubular inflatable belt and a buckle (see also Division E2) incorporating a gas cylinder which is punctured by an actuating lever on the fastener. In one embodiment one part 15 of the buckle is attached to one end of the belt whose other end is formed as a flat strip 5 which is held in releasable engagement around an adjuster 1 in a housing 13 which forms the other part of the buckle. A gas cylinder 16 is mounted in the part 15 and is moved axially against a piercing pin by pulling a handle 10 which moves a lever 6 carrying a pressure plate 4. The pressure plate 4 carries a pad 2 which normally abuts the portion of the belt end 5 surrounding the adjuster 1 to hold it in tension but, on pulling the handle 10, the plate 4 moves against the cylinder 16 and axially displaces it and the pad 2 is disengaged from the belt end 5 to allow it to release tension in the belt and allow it to expand as it inflates. In an alternative construction (not shown) a lanyard surrounds the belt and is connected to a lever on a buckle. Upon pulling the lanyard, the lever pivots and displaces a piercing pin which punctures a gas cylinder mounted in the fastener to inflate the belt.

Filed: 1924-08-05
Abstract: 229,200. Schwarzenhauer, W., and Bing-Werke vorm. Geb.-Bing Akt.- Ges. Aug. 5, 1924. Mechanical toys.-The field magnet of a toy locomotive is divided, one part being pivoted whereby when the current is interrupted the part moves to operate a spring-influenced switch lever which rotates a commutator and effects reversal of the drive. The pole-piece 3 is pivoted at 4 and is fitted with a transverse pin 5 engaging the switch lever 7 pivoted at 8. The switch lever is provided with a pivoted member 12 having a tooth 31 engaging arms 32 on a commutator A on its upward movement; its downward movement is idle. When the current is on the parts are in their full-line position. Interruption of the current de-energizes the coil 17 and allows the spring 30 to depress the switch lever to its broken-line position. Subsequent application of the current depresses the pole-piece by energizing the coil, the switch arm being raised to rotate the commutator A through 90‹. The reversing gear may be thrown out of action by moving a slide to engage the pin 5.
Patent GB-431812-A (GB)
Title: Improvements in crystallization
IPC: B01D21/00
Filed: 1934-06-25
Abstract: In the removal of minor crystallizable constituents or impurities contained in solution in a main solution, the minor constituents being of the kind that show decreasing solubility at increasing concentration of the main solution, the main solution is continuously concentrated within the metastable range of said minor constituents so as not to permit spontaneous crystallization thereof and is then mixed with fresh feed in such proportions that the mixture is supersaturated to such a degree that the minor constituents are precipitated and removed.  The process is applicable to the removal from a solution of phosphoric acid of silicofluorides which on concentration of the acid tend to deposit as fluosilicates on the evaporator surfaces.  Phosphoric acid solution is circulated continuously through a sedimentation tank 27 and an evaporator 12 at a speed controlled by a valve 37.  The solution is concentrated <PICT:0431812/III/1> in the evaporator 12 within the metastable range and then passes through a barometric pipe 22 into a vessel 23 to which fresh feed is added through a pipe 24 at a rate controlled by a valve 25 so that the impurities crystallize out in the tank 23.  The solution is then pumped to the tank 27 where the crystals settle out and are removed through an outlet 32 and pipe 33, a portion being returned through a line 34 for seeding the solution in the tank 23. The evaporator is provided with a trap 15 and condenser 13.

Title: Improvements in casings for electric accumulators
IPC: H01M50/121
Filed: 1934-06-25
Abstract: A container for a storage battery is made by first forming an inner protective lining of ebonite or other material having a high degree of mechanical, electrical and chemical resistance, and then moulding round the lining an outer casing of a material having these qualities in an inferior degree such as a composition having a base of bitumen, resin or asbestos.  The lining and outer casing are intimately connected by the moulding process which may be effected at a temperature above the softening points of the two materials which are thus partially fused and welded together. Intimate connection between the lining and casing may also be obtained by a solvent such as benzene applied to the lining after it has been placed in the mould. If the lining is made of transparent material apertures may be left in the outer casing to enable the level of the electrolyte to be observed.

Abstract: 1,142,532. Electrophonic musical instruments. H. B. STINSON, and I. G. NOON. 29 April, 1966 [24 Oct., 1965], No. 19013/66. Heading G5J. In an electrophonic instrument having a chromatic key manual in which the playing surfaces of certain (black) keys are raised relative to the surfaces of other keys an additional keyboard with key surfaces in one plane and each key aligned with a corresponding key of the chromatic manual is provided. As described, in addition to the usual manuals 11 and 12 and voice stops 13, the organ is provided with additional keyboards 15 and 16. The keys of the keyboard 15 are horizontally aligned with corresponding keys on the keyboard 12, but have their upper faces in a single plane level with the upper faces of the black notes of the keyboard 12. Corresponding keys operate contacts in parallel controlling a common tone generator and thus will sound the same note. The keyboard 15 which can be engaged by the same hand as the keyboard 12 can be wiped by the fingers to play chromatic scales. The keys of the keyboard 16 are each horizontally aligned with three keys of the keyboard 15 and in addition to operating three corresponding switch contacts, operate a fourth contact associated with the next key to the right on the keyboard 15. Each of these contacts is connected in series with a contact operated by a corresponding key on the keyboard 11 and in series with contacts operated by all octavely related keys on that keyboard, thus if the keys of a chord are held in a depressed position on the keyboard 11 while the keyboard 16 is wiped by the fingers, arpeggios of the chord and octavely related chords are produced. In a modification a single keyboard which under the control of a switch functions in either of the keyboards 15 or 16 replaces these keyboards. The keys (17, 19 and 60, see Figs. 5 and 7, not shown) are made of plastics material and are rigidly mounted in cantilever fashion.
