Title: Apparatus for measuring the thickness of sheets of ferromagnetic materials
Inventor: LACK KEITH MALCOLM
IPC: G01B7/06
Filed: 1965-07-21
Abstract: 1,097,179. Measuring thickness electromagnetically. TELEDICTOR Ltd. April 1, 1966 [July 21, 1965], No. 30990/65. Heading G1N. The thickness of a ferromagnetic sheet is measured indirectly by saturating it magnetically in the direction of its plane faces and measuring the total flux passing through it, which is proportional to the sheet thickness. The plate D is placed on a flux cylinder 13, Fig. 1, resting on the upper surface of a cylindrical permanent magnet 10, sufficiently strong to saturate the sheet, the magnetic circuit being completed by a flux plate 11 which is sufficiently large not to be saturated. The flux passing through the plate D is measured by a search coil 121 wound round a laminated core 12 having a square loop characteristic and a constant incremental permeability. The annular gap between the core and cylinder 13 is filled with a non-conducting plastics material (17), Fig. 3 (not shown), e.g. polyester resin cured in situ. In operation an A. C. e. m. f. is applied to the search coil 121, serially connected to a resistance 141 which is connected across an amplifier 14 designed to amplify only unidirectional pulses of an alternating current. The unidirectional pulses across the resistance 141, having amplitudes proportional to the flux in the core 12 and therefore to the thickness of the plate (due to the properties of the core 12), are transmitted to the scanning coils of a CRO 15 to deflect its beam from a zero point 0 of a scale 16, calibrated in steel thickness. In a modification, the magnet 10 may be replaced by an electromagnet and the cylinder 13 may be omitted. Further, more than one search coil may be used.

Title: Improvements relating to adjustable seats
IPC: B60N2/16
Filed: 1932-11-03
Abstract: 409,744. Seat adjustments. CHAPMAN, A. W., 115, Howards Lane, Putney, London. Nov. 3, 1932, No. 31038. [Class 52 (ii).] In an adjustable seat of the type in which a seat - supporting member is connected by pairs of crossed levers to a fixed member, at least two sets of levers are used, each lever is pivoted at one end to one of the members and slidably connected at the other end to the other member, and means are provided for adjusting and retaining the seat member which in conjunction with the crossed levers, hold the seat member rigid in adjusted position. The adjusting means acts directly on the seat supporting member. In the form shown in Fig. 1, a seat-frame 1 is supported on a lower frame 2, which may be mounted on slides on the floor of a vehicle, by three pairs of levers, each consisting of levers 5, 6, arranged on three sides of the frames. The lower end of the lever 5 is pivoted to a bracket on the lower frame, while the lower end of the lever 6 is pivoted to a sliding bracket 10 which has an upturned lower edge engaging under the downturned edge of a bracket 13 secured to the lower frame, a line-contact sliding connection such as that described in Specification 379,902 being obtained. The upper end of the lever 6 is pivoted to the frame 1, and the upper end of the lever 5 is pivoted to a sliding bracket similar to the bracket 10. The two levers are pivoted together where they cross. The other pairs of levers are similarly arranged. The seat is adjusted and retained in position by means comprising a screwed rod 15 passing through a nut in a bracket 16 on the frame 1 and pivoted to a bracket on the lower frame 2, the nut being rotated through bevel gearing by a handle 21. Since the arms of each set of levers are equal, the frame 1 will remain parallel to the frame 2 during adjustment, but levers 24, 25, Fig. 5, with unequal arms may be used, in which case one edge of the seat frame will be moved through a greater distance than the other. In some cases, the seat frame may be hinged at one edge to the fixed frame. In the construction shown in Fig. 8, a pair of levers is arranged along one edge of the seat, and a second pair at right angles to the first under the centre of the seat.

Title: Improvements in and relating to the balancing of crank shafts with associated members such as connecting rods and pistons
IPC: F16F15/26
Filed: 1930-10-16
Abstract: 363,042. Lubricating passages in crank shafts and connecting-rods. WEAVER, I. A., 1319, South 1st Street, Springfield, Illinois, U.S.A. Oct. 16, 1930, No. 31052. [Class 12 (ii).] Internal-combustion &c. engines ,are balanced by the addition of a charge of oil to an axial cavity in the crank pins during the outward stroke, the ejection therefrom at the end of the stroke serving to withdraw surplus oil from the scraper ring groove in the piston. Oil is fed from the crank case 25 by a pump 26 to a chamber 23 on each main bearing, from which it passes during the out-stroke of the piston, by way of an inclined channel 32 in the crank web to an axial bore 29 in the crank pin. As the shaft rotates a passage 39 registers with the flared end 45 of a bore 43 in the connecting-rod and oil is conveyed under pressure to the gudgeon. After passing the lower dead centre, a port 35 in the crank pin aligns with two curved ports 37, 38 in the big end, which discharge the oil without shock into the crank case, the resultant suction in the bore 29 serving to withdraw by way of the bore 42 and passage 49 any oil in the scraper ring groove 51 in the piston.

Title: Improvements in or relating to telecommunications exchange systems
IPC: C01B25/30
Filed: 1968-06-28
Abstract: 1,206,543. Automatic exchange systems. SIEMENS A.G. 28 June, 1968 [30 June, 1967], No. 31096/68. Heading H4K. In an exchange which is centrally controlled by one of several markers at any time and in which peripheral equipments e.g. line circuits, relay sets or switching network components are arranged in groups and the groups are arranged in zones, a faulty equipment is detected and put-out of service by initially scanning the zones and then the groups within a zone and finally the units within a group in each case by successively closing normally-open contacts associated with the zones, the groups and the units, and thereafter, if the fault remains undetected, by scanning all the units in turn by opening normally-closed contacts associated with each unit. The latter scan is controlled by a random start counter which is never reset but merely starts stepping form the point reached during a search for a previous faulty equipment. It is suggested that this double scanning fault finding procedure overcomes faults arising in the fault-finding scanner itself without undue duplication of fault finding equipment. If a marker exhibits a fault, one of its partners is switched-in by the fault finder. Breakdown of a decoupling rectifier in a relay matrix, which is an example of a fault having a multiple effect, is detectable by initially locating the faulty row using the first scanning sequence and then the faulty column using the second scanning sequence.

Abstract: 818,358. Controlling helicopters. AEROTECNICA S.A. Oct. 31, 1955, No. 31104/55. Class 4. In a helicopter in which the rotor is driven by a gas turbine power plant, a proportion of the exhaust gases are fed to a duct 1 at the tail end of the fuselage to be ejected laterally through an orifice 3 to provide an anti-torque control effect. The rear wall of duct 1 has an opening 4, 5 and the duct encloses deflector vanes 6, 7 which are connected by linkage to a spring loaded arm 10 having a forwardfacing cup 11 at one end. Further deflector vanes 8, 9 within the duct are connected by a linkage 15 to the pilot's rudder bar and to a pair of laterally disposed rudders 13, 14. During take-off and low translational speed before the rudder control becomes effective, the spring 12 holds the flaps 6, 7 in the deflected position shown whereby the gases are guided past flaps 8 and 9 through orifice 3. At a selected forward speed air pressure on cup 11 overcomes the tension of spring 12 and deflects flaps 6, 7 to a position where a proportion of the exhaust gases are directed rearwardly through opening 4, 5 to assist in forward propulsion. Movement of control mechanism 15 moves flaps 8, 9 in conjunction with rudders 13 and 14 so that the exhaust gases are deflected in a direction to assist the rudder action.

Title: Curing systems for polyester resins
Inventor: SARGENT EDWARD HENRY GEORGE
IPC: C08F283/01
Filed: 1961-08-29
Abstract: 941,660. Curing polyester resins. DRAYTON RESEARCH Ltd. Aug. 28, 1962 [Aug. 29, 1961], No. 31113/61. Heading C3P. Unsaturated polyester resins are cured by reacting the unsaturated polyester resin with a vinyl monomer in the presence of a peroxide catalyst and, as an accelerator, an N-dialkyl substituted aromatic amine containing a para carboxylic acid group, or an ester or salt thereof. The polyester resins consist of the condensation product of a polyfunctional carboxylic acid with a polyol one or both of which contain, ethylenic unsaturation. Preferably an ethylenically unsaturated dicarboxylic acid e.g. maleic, fumaric or adipic, is reacted with a glycol e.g. ethylene, diethylene, propylene or dipropylene glycol and in addition a saturated dicarboxylic acid e.g. succinic, phthalic or isophthalic, is also present. Polyester resins specified are those formed from maleic acid, isophthalic acid or phthalic acid and propylene glycol. Accelerators specified are butyl-p-dimethylamine benzoate, p-dimethylamino-benzoic acid and octyl-p-dimethylanine benzoate. Vinyl monomers mentioned are styrene, vinyl toluene, acrylonitrile and methymethacrylate. Conventional polymerization inhibitors such as phenolic compounds or quaternary ammonium compounds may be added to inhibit polymerization until the resin is mixed with the catalyst immediately prior to use. Catalysts mentioned are benzoyl and methyl ethyl ketone peroxides and cumene hydroperoxide. Fillers e.g. glass fibre, pigments and thixotropic agents may be added to the polyester mixture before the addition of the catalyst. In the examples the accelerators of the invention are compared with the known accelerators dimethylaniline, p-hydroxydimethylaniline and salicylic acid/dimethyl aniline. In the Provisional Specification 1 - dimethyl - amino - 2 - methyl - 4 - carboxy benzene is mentioned as an accelerator. The cured polyester resins can be used for large structures such as boat hulls.
