Title: Improvements in and connected with Apparatus for Administering Oxygen or other Gases.
Inventor: WARD JOHN AUGUSTUS
IPC: A62B7/02
Filed: 1916-10-12
Abstract: 107,990. Ward, J. A., and Read, F. O. Oct. 12, 1916. Inhalers; gas and vapour douches.-Apparatus for administering oxygen or other gases and vapours by inhalation or as a throat douche, comprises a gas cartridge 2 held within a casing 1 having a box substantially larger than the cartridge and provided with ventilation apertures 1<a>. The casing 1 is closed at the upper end by a screw plug 5 carrying a cutting-nipple 9, and at the lower end by a screw-plug 4 adapted to force the cartridge against the nipple 9 so as to pierce the sealing diaphragm and release the gas. The gas passes via an expansion chamber 11, needle valve 12, gasbag fitting 13, 14, non-return valve 16, and union 18 to a face mask. The valve 16 mav be combined with means for mixing the gas with atmospheric air. Fig. 3 shows an arrangement in which the cartridge container is connected to the chamber 11 by an elbow piece 11<a>. Figs. 4 and 5 show a modification in which the gas passes from the valve 12 through a chamber 20 containing an absorbent saturated with a medicated liquid to a nozzle 28. The chamber 20 surrounds a tube 21 which is perforated on each side of a partition 24 so that the gas takes the path indicated by the arrows. The cartridge containing case 1 may be replaced by a revolver-like fitting so that a number of cartridges may be used in succession.

Title: Packaging materials
IPC: B65D81/03
Filed: 1973-01-04
Abstract: 1448861 Embossed films and laminates thereof JIFFY PACKAGING CO Ltd 12 Sept 1973 [4 Jan 1973] 485/73 Headings B5B and B5N A flexible base film of substantially uniform thickness is provided with a plurality of generally hexagonal projections extending from one side. The projections have a peripheral wall extending substantially perpendicular to the plane of the sheet and an end wall substantially parallel to this plane. Each projection save those on the edge of the sheet is surrounded by six other projections at equal distances from it. It is preferred that the greatest distance across the peripheral wall is greater than its height. Preferably the projections are so arranged that each corner of the peripheral wall is opposite a corner in the wall of an adjacent projection, the distance between those corners being advantageously the same as the length of one of the sides of the hexagon. Webs 14 of substantially the same height as the projections may be provided to link the projections into parallel rows. Additional webs 15, of lower height than the projections, may also be provided, joining the projections into further parallel rows. Optionally the embossed film may be laminated to another film, thus closing the ends of the projections, and also to another film, on the other side of the embossed film and closing the spaces between the projections.

Title: Improvements in or relating to electrostatic machines
IPC: H02N1/08
Filed: 1949-01-07
Abstract: 669,645. Electrostatic machines. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Jan. 7, 1949 [Jan. 16, 1948], No. 487/49. Class 35. The current taken or generated by an electrostatic motor or generator is made smooth by arranging overlap between the active periods of the charge-carrying plates. The stationary plates comprise an oppositely-disposed main pair 21, 21a, separated by auxiliary plates 22, 22a, each pair being maintained at a potential, e.g. - v. and +2 v., by D.C. generators 50, 51, respectively. The rotor carries five mutually insulated charge-carrying plates connected to contact segments 23<SP>1</SP>, 23<SP>2</SP>, ... 23<SP>5</SP>, engaged in turn by the earthing brushes 24, 24a and the output brushes 25, 25a connected to the machine terminal 26. The spacing of the rotating contacts and the brushes is such that there is overlap between the active periods of the charge-carrying plates, at least one being connected to the output at any one time. Slight irregularities in output may be removed by means of variable smoothing condensers having plates rotated by the rotor shaft so that the capacity varies in the appropriate manner.
Patent GB-283182-A (GB)
Title: Improvements in machines for shaping pottery and like articles
IPC: B28B1/29
Filed: 1928-01-06
Abstract: 283,182. Miller, W. J. Jan. 6, 1927, [Convention date]. Pottery. throwing and turning. -Pottery-shaping apparatus comprises a series of moulds which is moved uninterruptedly in a path adjacent the shaping mechanism and means for intermittently moving such mechanism along with the moulds so as to permit the shaping operation to be carried out on one or more moulds without interrupting the movement of the moulds. The profile 83 is mounted upon a movable frame 11 supported by rollers 12 on rails 13. The mould-carriers 32 are pivoted to the trunnions of an endless chain conveyer 31 carried on sprockets 30 on a shaft 24 driven from the power shaft 16 by worm-gearing 18, 19 and gears 22, 23. Latches 34 pivoted on the movable frame 11 are adapted to engage the trunnions 33 of the chains 31 whereby the frame 11 is moved with the chains 31 until the latches 34 are disengaged by pins 31. Pins 91 on the frame 11 prevent undue rotation of the latches. The frame 11 is moved back to deal with the next mould by the pressure of a cam 45 mounted on a shaft 41 carried by the frame 11 against a lever 47 pivoted at one end to the frame 11 and at the other to a push-rod 50 pivoted to the rail 13 at 51. The cam-shaft 41 is rotated by a worm-wheel 42 engaging a worm 43 slidably keyed on the powershaft 16. The return movement of the frame 11 is assisted by a spring 55 abutting at one end against a fixed beam 56 and at the other against nuts 57, 57a on a rod 58. The rod 58 passes through an opening in the beam 56 and is connected to a piston 60 sliding in a cylinder 61 open at the left hand side. The return movement of the frame 11 is cushioned by the air in the cylinder, which air may be released at any desired rate by valves 98, 99. The moulds 82 are raised into contact with the profiles 83 by chucks 81 mounted on spindles 74 carried by the frame 11. The spindles 74 are reciprocated by pivoted levers 77 having rollers 79 contacting with cams 46 mounted on the shaft 41 as in Specification 280,882. The spindles 74 are rotated through friction gears 69, shaft 68 and bevel gears 66, 67 from a shaft 65. The shaft 65 may be driven by a motor carried by the frame 11 or through a pulley 100 slidably keyed thereto, by an external motor. Additional jiggers 87 may also be provided, which may be rotated and reciprocated independently of the spindle 74 but in synchronism with the movements of the frame 11 by cams driven from a separate motor. Specification 282,072 is also referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a construction in which the jiggers are stationary and the chains intermittently moved. This subject-matter does not appear in the Specification as accepted.

IPC: H03G3/22
Filed: 1927-01-07
Abstract: 288,371. Mathieu, G. A. Jan. 7, 1927. Thermionic amplifiers and detectors.-An automatic gain regulating device comprises a signal intensity reducing means e.g. an artificial line RN and a plurality of relays CR energized by currents proportional to the signal strength and adapted to be actuated in succession by rising values of current to vary the value of the intensity reducing means. Fig. 1 shows a supersonic heterodyne receiver T, a high frequency amplifier HFA and a detector separator DS adapted to separate the direct current component from the low-frequency alternating current produced by demodulation. The direct current component after amplification by amplifier DCA is passed through the main windings CW1 of a number of relays in series. Fig. 3 shows one such relay actuating a relay switch WR1 adapted to shortcircuit a series resistance section 1 and to open a shunt resistance section 1A in the artificial line RN. The response of the relay CW1 is adjusted by means of the winding ACW1 energized from a variable tapping point upon a potentiometer P1 through a variable resistance VR1.
