Title: Improvements in and relating to electric gauges
IPC: G01B7/02
Filed: 1941-09-03
Abstract: 548,687. Magnetic measurements determining dimensions of materials. BRITISH THOMSONHOUSTON CO., Ltd. (General Electric Co.). Sept. 3, 1941, No. 11243. [Class 37] An electromagnetic gauge comprises a pair of electromagnets and a pair of pivoted armatures with diametrically opposed feelers for the dimension to be measured, so arranged that the reactance of the windings is varied in accordance with the dimension to be measured, means being provided for measuring the reactance. A gauge head is shown supported in position by means of a bracket 12 for measuring the interval diameter of a machined cylindrical part 18. Projecting in opposite directions from a central part 22 of a magnetic core are spool-like portions 24, 25 wound with coils 26, 27. Armatures 33, 34 are pressed against pivots 35, 36 by a helical spring 30 located in a bore in the central part 22 and carry diamond points or feelers 14, 16 which are pressed into engagement with the internal surface of the body 18 under test by a spring 50. The air gaps between the armatures 33, 34 and the parts 24, 25 of the core are varied in accordance with the distance apart of the feelers 14, 16, the reactance of the windings 26, 27 is varied oppositely. These windings form two arms of an alternating current bridge, the indicator of which may be a current meter, recording instrument, or oscillograph. Slight movement of the test piece up or down relative to the bracket 12 causes both armatures 33, 34 to move in the same direction so that the ratio of the reactances of the coils 26, 27 is not appreciably affected and the balance of the bridge is not altered. The arrangement of the feelers 14, 16 and spring 50 may be modified for measuring external diameters.

Title: Improvements in fire control apparatus, determination of quadrant of enemy's course
IPC: G01C3/00
Filed: 1923-04-26
Abstract: 210,003. Barr & Stroud, Ltd., Barr, A., and Stroud, W. April 26, 1923. Addition to 208,266. Courses, determining.-In order to avoid the necessity of simultaneous observations in determining the " enemy's " quadrant, as in the parent Specification, apparatus is provided whereby observations from the subsidiary station are transmitted to the main station and the intermittent and non-simultaneous observations are visibly recorded on a travelling band by priokers or markers. Two inclinometers are used at stations C, A so as to give the observed angle at the station A and at the station C the angle as measured from an imaginary station P situated at the same distance from the target as the station A. A form of Wheatstone bridge circuit is utilised similar to that in the parent Specification and the observed values are transmitted to the recording apparatus by shafts 81, 101. The record is made on the travelling band 80 by markers 93, 95 operated from stations C, A respectively. Motion of the shaft 81 is transmitted to the screwed spindle 84 through differential gearing and moves a nut 86 which carries an electromagnet 87 energized from conductors 88, 89, upon the closng of a switch by the observer at the point C. The intermittent observations M of the subsidiary station are thus marked at the band 80. A pricker 95 is similarly actuated from the station A. A broadside on position is indicated when the series of marks lie on a continuous curve, and when the points are on separate curves the " enemy " course is in one or other quadrant according to whether the curve of the marks M is above or below that of the marks N. When the. nut 86 or the nut of the pricker 95 reaches one end or the other of the screw 84 both are moved across the band 80 by the handle 96 and gearing 97, 98, 99.

Title: Improvements in prepayment gas meters
IPC: G07F15/02
Filed: 1935-04-12
Abstract: 455,225. Prepayment mechanism for gas meters. SOUTH METROPOLITAN GAS CO., SMITH, C. H., COLEMAN, E., and DOUGHTY, T. A., 709, Old Kent Road, London. April 12, 1935, No. 11415. [Class 27] Coin action, with stationary coin forming abutment and with delivery proportionate to value of coin.-A prepayment mechanism for gas-meters of the kind which can be selectively operated by two coins of different diameters, e.g. a penny and a shilling, and in which the handle rotated by the consumer operates differential gears in axial alignment with each other, comprises a shaft 6 on which is mounted two differential gears 12, 15, 13 and 13, 15<a>, 12<a>, the wheel 12 being fixed to the shaft and the wheels 12<a>, 13 being loosely mounted thereon. The wheel 13 is a double wheel common to both gears and is connected by an arm 16 to a handle 1 so as to be rotated thereby. The planet wheels 15, 15a are mounted in cages 14, 14<a> respectively which are rotatable on the shaft 6 and are in the form of toothed wheels. A penny or a shilling inserted into a channel 29 engages the tooth spaces in the cages 14, 14<a> respectively and locks these against rotation, the shilling being located by the end of the channel 29 and the penny by a stop 31 carried by a fixed side of the channel, the other side of which is pivoted. When a penny is used, the cage 14 is locked and rotation of the wheel 13 by the handle 1 causes the wheel 12 and shaft 6 to rotate until a stop 20 on a drum 3 fixed to the handle engages a stop 21 on the movable side of the channel 29. The channel is thus opened and the penny drops out. If a shilling is used, the cage 14a is locked and the wheel 12<a> is given the same rotation as was the wheel 12 for a penny. The wheel 12<a> is mounted on a sleeve 22 carrying a cradle 23 in which is rotatably mounted a spindle 24 having fixed to it two unequal toothed wheels 25, 26 meshing respectively with wheels 27, 28. The wheel 27 is fixed to the shaft 6 and the wheel 28 to a sleeve 8 loose on the shaft, and the gearing is such that the sleeve 8 is rotated twelve times as much for a shilling as for a penny. The sleeve 8 sets forward in known manner through an epicyclic mechanism an arm 9 carrying a valve-operating stop 10, the arm 9 with stop 10 being returned to its initial position by the metering mechanism during consumption of gas. Price-changing mechanism.-The drum 3 attached to the handle 1 has a number of perforations 4 into any one of which, according to the price of gas, a pin 17 on the arm 16 is inserted and held by a finger lever 18.

Title: Circular te-on mode filter
IPC: H01P3/13
Filed: 1974-03-14
Abstract: 1469152 Mode filters FUJIKURA CABLE WORKS Ltd 14 March 1974 [24 March 1973 14 April 1973 18 May 1973 18 June 1973] 11506/74 Heading H1W A mode filter for a circular waveguide system propagating the circular-electric TE 01  mode comprises a waveguide section with crosssectional deformations defined by a = a 0 (1 + #p#) where a 0  is the radius of the circle, p the number of deformations which is greater than 5, # the maximum amplitude of the deformations and (a, #) are angular co-ordinates. The deformations may be in the form of longitudinal ridges. The cross-section of the filter for p = 5 is shown in Fig. 3. It is stated that mode conversion TE on (n#2)#TE pm  is much greater than mode conversion from TE 01  to other modes. The desired conversion attains a maximum when the difference in phase constants of the two modes attains a minimum and this gives a criterion for choosing p, details of which are tabulated in the specification. It is stated that the attenuations of the TE on  modes is many times greater than that of the TE 01  mode for values of p equal to 5, 6 and greater numbers. The specification gives an expression for calculating the optimum length of the filter. Instead of a plain conductive waveguide, a helix waveguide as shown in Fig. 5, where p = 5, may be used. The waveguide consists of a helix 12-1 of insulated wire spaced from an outer conductor 12-3 by a dielectric layer 12À2. It is shown that a filter with p=5 (as shown) is most effective for conversion of the TE 02  mode and the specification gives a detailed numerical example including the criteria used in choosing the dimensions of the ridges. The invention may also be applied to the kind of circular TE 01  waveguide using a dielectric liner (see Fig. 8, not shown). In order to deal with a wide band of frequencies, the filter may be split into several sections each effective over a subband, the sections being separated by ordinary helix waveguide sections capable of absorbing TE pq  modes (see Fig. 10, not shown). In a further embodiment, Fig. 13, also designed for a wide frequency band, two filters of identical cross-section (p = 9) are arranged immediately adjacent each other and are rotated with respect to each other through an angle #=2#/4p. It is stated that the two filters operate without mutual interference.

Title: Production of organoborons
IPC: C07F5/02
Filed: 1960-04-01
Abstract: Organoboranes are made by reacting an organooxy boroxine of the formula (ROBO)3, wherein R is an organic group and the three R groups have a total number of carbon atoms not exceeding 30, with an organo aluminium compound.  The reaction proceeds very readily at room temperature and the reaction is preferably performed at between 20 DEG C. and 50 DEG C. employing 3 to 4 moles of the organo aluminium compound per mole of the organooxy boroxine. The organooxy boroxine may be prepared by adding 1 to 2 moles of boric oxide per mole of an appropriate borate ester and reacting at temperatures up to 400 DEG C. and higher.  Suitable organooxy boroxines are trimethoxy boroxine, triethoxy boroxine and corresponding compounds in which the group R is octyl, octadecyl, tricosyl, vinyl, propenyl, cyclohexyl, 1-hexynyl, phenyl or naphthyl.  The organo aluminium compounds include trimethyl, triethyl and other trialkyls, tripropenyl, trihexenyl, tricyclopentyl, tricyclohexyl, tri-1-hexynyl, tribenzyl, triphenyl, trinaphthyl, dimethylethyl, diethylmethyl aluminium and other organo aluminium compounds such as diethylaluminium chloride, bromide, iodide or fluoride, ethyl aluminium dichloride and diethylaluminium hydride.  Suitable solvents are hydrocarbons, ethers and tertiary amines.  On completion of the reaction, the organoborane is removed by distillation and the aluminium alkoxide by-product is hydrolysed to release the alcohol residue which can be reacted with boric acid, boric oxide or borax and sulphuric acid to produce the borate ester, and the latter is readily converted back to the organooxy boroxine by heating with boric oxide.  Reference has been directed by the Comptroller to Specification 815,140.

Abstract: 854,581. Electron beam apparatus. WILDBARFIELD ELECTRIC FURNACES Ltd. April 7, 1959 [May 5, 1958], No. 11791/59. Class 39(1). [Also in Group XXII] An electron beam furnace for welding volatile-containing metals to produce gas-free welds comprises a preferably concave tantalum or tungsten cathode 24 with a heater 28 mounted in a cathode chamber 26 and emitting electrons which are formed by a focusing electrode 30 and an accelerating anode 32 into a beam 34 which is focused by coils 50 to pass through apertures in partitions 40, 42 and 44 into a furnace chamber 10 containing a work support 12 mounted on a carriage 14 which is movable on rollers 18 under the control of a screw 15. The work support 12 is cooled by water passing through pipes 22 and is movable normal to the movement of carriage 14 by a screw 16. The electron beam maintains a pool of molten metal on the surface of a work-piece 13 at the location of the weld. A high capacity mechanical blower or diffusion pump 20 maintains the furnace chamber 10 at a pressure of from 1 to 10 microns of mercury, which is a sufficiently high vacuum to permit formation of pure welds in metals such as titanium, zirconium, tantalum and niobium. It will also permit dissociation or volatilization of many oxides and nitrides, particularly of the Group V and VI metals. The cathode chamber 26 is maintained at a pressure of about 0À01 micron of mercury by a pump 36. Pumps 46 and 48 maintain the spaces between the partitions 40, 42 and 44 at pressures of about 0À1 and 1 micron of mercury respectively. The tube 38 may contain a valve which can be shut when workpieces are being changed to maintain a high vacuum at all times in the vicinity of the cathode 24. The welding can be carried out under a partial pressure of a treating gas if desired.
