Title: Method of and apparatus for measuring the contact forces of an electrical switch contact
IPC: H01H11/00
Filed: 1963-06-06
Abstract: 979, 692. Electric selective signalling systems. SCHALTBAU-G.m.b.H. June 6, 1963 [June 8, 1962], No. 22563/63. Heading G4H. In a system for measuring the contact force on an electrical contact a steadily increasing force is applied to the contact and its opening is used to initiate the recording, in digital form, of the force then applied to it. The force is applied to the contact by a spring balance having a points Fig. 4 moving over a coded scale having conducti and non-conductive regions and the opening of the contact causes the reading from the scale to be registered on transistor triggers. In a modification the coded scale is replaced by two contacts Fig. 8 set to correspond to the range in which it i desired that the contact force lie. Then depending upon when the contact opens a logic circuit (Figs and 11 not shown) produces a "low", "O.K." or "high" indication on one of three leads. The Specification refers to the use of these signals in an automatic system for setting the contact forces to the desired range.

Title: Improvements in or relating to process of an aromatic carboxylic acid
IPC: C07C51/265
Filed: 1956-07-20
Abstract: Aromatic carboxylic acids are prepared by the oxidation of a solution of a monoaryl compound, having at least one methyl nuclear substituent, with an oxygen containing gas having a partial pressure of oxygen of at least 0.85 atmosphere, in the presence of 0.1 to 0.5 mol. of a methylenic ketone per mol. of aryl compound, between 60-120 DEG  C.  The mono-aryl compound is dissolved in a C2-C4 fatty acid, the resulting solution containing 0.5-5 mols. per litre of water, 0.1 to 3.0 mols. per litre of aryl compound and 0.02-0.2 mols. of cobalt salt of said fatty acid per mol. of aryl compound.  Suitable cobalt salts are the acetate, propionate and butyrate, and suitable solvents the corresponding acids or their mixtures. Examples of methylenic ketones which may be used are methyl ethyl ketone, diethyl ketone, methyl propyl ketones, 2,4 pentane dione and 2,5 hexanedione. Suitable starting materials are toluene xylenes and derivatives thereof having additional nuclear substituents inert to the oxidation reaction, e.g. chlorine, bromine, fluorine, nitro, tertiary alkyl, carboxyl or alkoxy. Examples are given of the preparation of benzoic acid from toluene, terephthalic acid from p-xylene, terephthalic acid from p-toluic acid, chloroterephthalic acid and its dimethyl ester from 1,4 dimethyl-2-chlorobenzene, isophthalic acid from m-xylene, and mixtures of acids from mixed xylenes.  The mixed acids are separated by converting the mixture into an aqueous solution of their sodium salts and treating the solution with barium nitrate solution to precipitate the insoluble barium terephthalate salt. This precipitate is removed by filtration, and yields terephthalic acid after digestion with hydrochloric acid, whilst the filtrate yields isophthalic acid or similar treatment.  The reaction may be carried out in two stages, by first heating the reactants for several hours at about 100 DEG  C. and then for a longer period at 70-80 DEG  C. In an example describing the preparation of terephthalic acid from p-xylene using this technique, the filtrate obtained on filtration of the product from the reaction mixture is re-used by adding fresh p-xylene and methyl ethyl ketone to it.  The re-use of the filtrate may be repeated by maintaining the water content of the solution at between 1/2 and 3 molar, e.g. by distillation in the presence of benzene, or contacting the solution for a suitable length of time with silica gel or dhydrated gypsum, before re-cycling to the reaction vessel.

[Also in Divisions B4 and E1] Apparatus for driving, or extracting, a pile 1, Fig. 6, by vibration thereof comprises a block 5 supporting a vibrator, or periodic force generator, 2 on tension springs 6 and carrying an hydraulic motor 7, Fig. 7, for rotating a pair of eccentrically-loaded cylinders 12, 13 within the generator through worm and worm-wheel gearing 8a, 9, 10 and couplings 17, said cylinders being supported by a fluid or hydrostatic bearing system (14, 15), Fig. 3 (not shown), within a block 11. The gearing aforesaid is such that in operation the cylinders are contra-rotating to minimize transverse vibrations. Each of the couplings 17 includes a block (18), Fig. 5 (not shown), which is slidingly lodged between two mutually-perpendicular pairs of jaws 19, 20 on the ends of the corresponding worm and cylinder, a fluid-bearing system comprising recesses or pockets (21) in the block (18) being provided to minimize conveyance of vibrations from the cylinder to the motor. The motor 7 and the fluid-bearing systems are supplied with pressurized oil by pumps (22, 26), Fig. 1 (not shown), which are coupled to an I.C. engine (29), the spent oil being returned to a sump (25) through a cooler (30). In operation, the frequency of the vibrations generated in the pile is one other than the natural frequency of the pile in combination with the apparatus and such that the amplitude at the lowermost end of the pile does not exceed one half of that which would occur at the natural frequency. The generator may be such that the periodic force is variable. The generator 2 may be modified such that vibration is effected by a pair of contra-rotating eccentric masses 37, Fig. 8, each mass being attached to a sleeve 35 that is rotatably mounted on a fixed stub-shaft 34, which is secured to the block 11, a block 31 being slidingly lodged between jaws 36 at one end of said sleeve and engaged by the jaws 19, Figs. 6 and 7. The apparatus may be modified to produce either transverse or torsional vibrations, and may be used to vibrate elastic elements other than piles, e.g. drills, mandrels and tubes, so as to drive them into, or extract them from, e.g. soils, rocks, minerals, concrete, masonry and roads. An article such as an instrument can be vibration-tested while it is mounted on a bar that is subjected to vibration by apparatus similar to that aforesaid.

Abstract: 611,505. Magnetrons. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 17, 1944, No. 22918. Convention date, Nov. 19, 1943. [Class 39 (i)] A cavity magnetron has alternate anode segments 22 shorter than the ones 23 between, segments 23 being connected to conductive end plates 24, 25 and segments 22 being spaced from the end plates so that each short segment forms the inner conductor of a quarter-wave coaxial line terminated at the end by cylindrical member 21, to which all the segments are connected. The member 21 forms the inner wall of a cylindrical resonator 30, which is coupled to each quarter-wave line by apertures 35, 36 placed alternately at the top and bottom, as shown in Fig. 6. The developed view of Fig. 5 shows that a master wave in resonator 30 of Eo type will produce a circumferential magnetic field coupled to consecutive quarter-wave lines in opposite directions, so that each short segment 22 is constrained to oscillate in anti-phase with its neighbours. Mode-changing is thereby eliminted. Magnetic inserts 26, 27, Fig. 4, co-operate with external polepieces 261, 271 and also support the indirectly-heated cathode 20. The resonator 30 is preferably dimensioned so that the ratio of its outer radius b to its inner radius a is greater than 2. A coupling loop 37 or a wave-guide removes energy from the system.

Abstract: 1353836 Counting apparatus BENDIX CORP 16 May 1972 [25 May 1971] 22968/72 Headings G4A and G4D A counting system for registering the difference between positive and negative pulse inputs F, R is designed to overcome the problem of reading a rapidly fluctuating value. The system involves a main counter 18 which displays the result and a low capacity, auxiliary counter 24; the incoming pulses are normally directed to the auxiliary counter 24 but when it reaches its limit in either direction further input pulses in that direction are diverted into the main counter. The value in the auxiliary counter 24 is sampled at intervals and an average value is registered on a further counter 62. At intervals determined by a clock 48 the value in the average counter 62 is added (algebraically) to the main counter and subtracted from the auxiliary counter to correct the reading on the main counter. In a simpler form of the invention (Fig. 1, not shown) the averager 32 simply determines the sign of the average and then at intervals causes a single count to be transferred from the auxiliary to the main counter, or vice versa, according to the sign. Detailed circuitry for each element of Fig. 2 is given in the Specification.

Filed: 1947-08-20
Abstract: 631,287. Rotary pumps and engines. SPIES, V. J. B. Aug. 20, 1947, No. 23058. [A Specification was laid open to inspection under Sect. 91 of the Acts Feb 3, 1948] [Class 110(ii)] The pump or engine has an eccentric piston rotor 22, in a working chamber 20, and a hinged-abutment 32 exposed on either side to high and low pressures through ports 14, 13 respectively. An excessive pressure under the abutment lifts the end 30 clear of the rotor 22, allowing fluid under pressure to flow to the low pressure side. The position of a spring 37, bearing on the abutment, may be adjusted by means of a plug 38. The eccentricity of the rotor, mounted on a spindle 43, may vary automatically through opposing spring means and centrifugal force acting on a mass 46, carried by a disc 44, which is pivoted on a pin 45. The spring 48 presses the mass 46, and the eccentric spindle 43, into a position of greatest eccentricity. This arrangement lessens wear on the rotor periphery at high speed and causes a limitation to the high pressure in the working chamber. Fig. 6 shows a modification in which a rotor mounting has an adjustment means to limit the delivery pressure or speed of the pump. A pin 49 is mounted on a disc 51, between discs 44 and 46, disc 51 being adjustable angularly on an extension of the shaft 23. A screw 54 holds the disc 51 in position. The rotor comprises an annular steel core, on the spindle 43, carrying a ring 62 of anti-friction metal formed in two parts which engages the working chamber bore. The parts may be pressed apart axially by springs. A hollow extension 24 carries oil for lubricating bearings 25, 26. Seals 28, 29 are provided. The spindle 23 carries a driving (or driven) pulley 27.
