Title: Improvements in or relating to heat-treatment furnaces, kilns, stoves and similar structures or installations
IPC: C21D9/00
Filed: 1933-12-29
Abstract: 429,782. Endless conveyers ; rollerway conveyers. BIRMINGHAM ELECTRIC FURNACES, Ltd., and LOBLEY, A. G., Tyburn Road, Erdington, Birmingham. Dec. 29, 1933, No. 36546. [Class 78 (i)] [See also Group XII] The position of a charge within a continuous tunnel furnace is indicated by a tab b which is attached to an external endless band a as the charge enters the tunnel, the band a being driven from the furnace conveyer so that the tab travels at the same rate and in the same direction as the charge. To permit ready attachment of the tabs and prevent their displacement by the driving connections, the drive is transmitted by pulleys c to the lower run a<2> of the band a, the upper run a<1>, on to which the tabs are clipped, being supported and guided by a channel member d. The indicator is particularly applicable to the double-track counterflow furnace described in Specification 415,423, [Group XII], a band a, driven in the same direction as its associated roller-way conveyer, being provided on each side of the furnace.

Title: Improved arrangements for separating or separately detecting charged particles of different specific charges
IPC: H01J49/42
Filed: 1954-12-20
Abstract: 773,689. Mass spectrometers. PAUL, W. Dec. 20, 1954 [Dec. 23, 1953], No. 36738/54. Class 39(1). A high-frequency mass spectrometer has an electric field of potential ° = f(t). (alphax<2>+#y<2>- alphaz<2>) and ions either oscillate with a limited amplitude (stable paths) or oscillate with increasing amplitude (unstable paths) until they hit the electrodes depending on their specific charges. The separation is determined by varying at least one of the quantities, amplitude frequency and shape of the voltage f(t). The electrodes are hyperbolic sheets, Fig. 1, or rods ; circular rods are an adequate approximation. A bank of electrodes, Fig. 10, may be used. A D.C. voltage is also applied so that f(t) = Uo + V cos wt and the ratio Uo/V determines a stable range of ion paths. The ions are projected through the field from a conventional ion source, or, Fig. 12, created within the field. Electrons from a filament 17 are projected into the field through one of the electrodes B. Electrodes A, B, B are one and two-part hyperboloids of revolution. The ions are detected either as a lagging load in the A.C. circuit if in a stable range, or as a non-reactive load if in an unstable range. By superimposing an additional A.C. voltage of small amplitude and half the frequency, ions of a particular mass which resonate with the additional field may be separated out. The ion paths are discussed with reference to the differential equations of motion which are of Mathieu type.

A character-bearing annulus for use with a telephone dial has projections which engage with the rear surface of the dial case while at least part of the rear face of the annulus engages with the face of the stand or casing on which the dial is mounted. In Figs. 1 and 3 the annulus 1 is chamfered and has two webs 3, 4 bearing holes 6 into which rubber studs 7 are fixed. The heads of the rubber studs 7 engage the rim of the dial case 13 whereby the rear face of the annulus 1 is held firmly against the casing 12. The annulus can be engaged over the dial mechanism when the latter is removed from the casing without breaking the electrical connections. In Figs. 5 and 6 the webs are replaced by three resilient projections 21. The characters may be on the front or back of the annulus, which in the latter case is of a non- scratch, transparent, material.

Title: Improvements in and relating to the measurement of humidity
IPC: G01N25/64
Filed: 1929-12-02
Abstract: 336,855. Cambridge Instrument Co., Ltd., Orchard, J. L., and Glover, H. T. Dec. 2, 1929. Hygrometric apparatus.-Apparatus of the wet and dry bulb type for measuring the humidity of gases comprises electric resistance thermometers mounted close together in the gas stream, the whole of the wire of the dry thermometer being exposed to the gas and the wire of the wet thermometer being woven or sewn into or covered with a suitable fabric so that the whole of the wire is covered or surrounded by the fabric which is maintained in a saturated condition. The Figure shows a Wheatstone bridge arrangement for effecting the measurement, the thermometer elements 1, 2 being arranged in series with fixed resistances 5, 6 in two arms of the bridge, of which the other arms comprise fixed resistances 3, 4. The measuring instrument 7 is preferably of recording type. To obtain direct readings of relative humidity the sensitivity of the instrument 7 is adjusted to suit the dry bulb temperature by arranging on the bridge arm 2, 6, an auxiliary bridge circuit comprising equal fixed resistances 8, 9 and a rheostat 10 operated by pendulum mechanism of the kind described in Specification 337,552, [Class 118 (ii), Signals], and a relay 11. The adjustment is such that when the dry bulb temperature is 60‹ F. the relay will balance when the moving arm of the rheostat 10 is in its central position. At any other temperature the moving arm takes up a balance position. The moving arm of a rheostat 12 in series with the instrument 7 is arranged to be adjusted in synchronism with the arm of the rheostat 10 to effect the adjustment of the sensitivity of the instrument. A shunt 13 having a resistance equal to the sum of 8 + 9 + 10 is placed across the arm 1, 5. For calibration purposes standard resistances 17, 18 are adapted to be included in the bridge circuit in place of the arms 1, 5 and 2, 6 by means of a throw-over switch 14 which is also arranged to include a fixed resistance in series with the instrument 7 instead of the rheostat 12. A rheostat 19 in the battery circuit is then adjusted until the reading of the instrument 7 attains a predetermined value.

Class 102(2) [Also in Groups XIII and XXIX] A piston valve 32, having steam ports 40a and air ports 41a. is operated by an extension 30 of the rod 26 of a float 22 of a steam trap to slide in a guide 33 having corresponding ports 40, 41 opening to a steam chest 36 and an air chest 38 respectively the chests being formed in a chamber 34 by a partition 35. When the float chamber 21 is full of condensate and the float has risen to the position shown, steam from an inlet 37 enters the float chamber 21 by way of the chest 36, ports 40, 40a and the interiors of both the piston valve 32 and a casing 42, to force the condensate back to a boiler, e.g. of a central heating. system. When the condensate has left the chamber 21, the float 22 falls together with the piston valve 32 so that the air ports 41, 41a are in communication, but the steam ports 40, 40a are not, and the float chamber communicates with the air chest 38 and an air vent 39. The trap is similar to those described in Specification 646,840, in which their method of use in a central heating system is shown. A snap action of the float and valve is obtained by springs 53 bearing with adjustable pressure on plungers 51 connected by toggle links 50 with a collar 31 on the float rod 26 in the chamber 42.
