Abstract: 1,178,338. Heat treatment process and apparatus. AEG-ELOTHERM G.m.b.H. Feb.13, 1968 [April 29, 1967], No.7139/68. Heading C7N. [Also in Division H5] An elongate workpiece of varying diameter is heat-treated to produce a region which is toughened throughout its cross-section and a portion which is surface hardened by first heating the workpiece non-uniformly along its length by relative movement of it and an inductor, and then heating it by induction uniformly along its length, including the region that was first heated; the workpiece is then hardened by quenching. Apparatus for carrying out the process comprises one or more inductors and means for moving them along the workpiece, including means for reversing or retarding their motion in the region to be heattreated; there may also be means for controlling the power and/or frequency of the current supplied to the inductors according to the position of the latter in relation to the workpiece. In the embodiment illustrated, inductor 3 is caused to heat that region 8 of workpiece 7 which is to be throughhardened, while inductor 6 travels to the flanged end of the workpiece, and then moves slowly upward, heating the surface zone 9 which is then quenched by spray 13. Conditions are such that when inductor 6 reaches inductor 3 zone 8 will have been heated throughout, and the two inductors then move from the workpiece together. Movement of the inductors over the workpiece may be repeated to effect annealing and/or tempering.

Title: Improvements in or relating to aerial merry-go-rounds
IPC: A63G1/34
Filed: 1943-05-10
Abstract: 569,219. Roundabouts. EYERLY, L. U. May 10, 1943, No. 7384. [Class 132 (i)] A roundabout in which aeroplane units travel about a vertical axis, includes means for permitting the aeroplanes to roll at higher elevations, but not at lower elevations. A central tube 18 supports a number of arms 28, to which are pivoted bell-cranks 35, the lower ends of which support spindles of aeroplane units 42. A crank arm 47 on the spindle is connected by a cable 31 to the end 30 of the arm 28, and with the aeroplane in lowermost position, the cable and crank arm maintain the aeroplane in vertical position. A cable 38 stretches from an eye 39 on the bell-crank over a block 37 to a spring 41, the other end of which is connected by a cable to a drum 14 on a vertical spindle 13. When a motor 17 drives the spindle 13, the drum 14 winds up some of the cable 40 and the aeroplane rises from the ground, and together with the arm 28 begins to rotate about the central support. The cable 31 is now slack, and the occupant of the aeroplane can operate the ailerons to rise or fall within the limits allowed by the spring 41 or to roll. In Fig. 6, the aeroplane 82 is suspended by a pair of cables 91 from an arm 95, while the crank on the spindle of the aeroplane is secured to a cable 102 incorporating a spring 104 which maintains the aeroplane level until the speed of the roundabout has lifted the aeroplane which can then roll, rise or fall under the control of the occupant. In Fig. 11, the aeroplane 42 is supported by a bell-crank 133 connected by a cable 144 to a drum 143. The crank on the spindle is connected by a cable 140 to a coupling 145 on the other cable. In lower positions, the aeroplane is supported by the cable 140, but in the higher positions by the cable 144, the cable 140 then being slack and permitting manoeuvring.

Title: Improvements in or relating to the manufacture of etherified melamine-formaldehyde resins
Inventor: SWANN GEOFFREY
IPC: C08G12/42
Filed: 1953-03-18
Abstract: An etherified melamine-formaldehyde resin is made by condensing melamine with aqueous formaldehyde, or a substance yielding formaldehyde, in presence of an alkaline catalyst which is calcium, barium or strontium hydroxide and condensing the product, preferably after removal of most of the water, with an aliphatic monohydric alcohol containing 3-5 carbon atoms in the presence of an acidic catalyst which is provided by passing a stream of carbon dioxide through the reaction mixture.  The alkaline catalyst of the first stage is precipitated as carbonate in the second stage and may be filtered off.  Preferably 3.5-7 moles of formaldehyde and 4.5-7 moles of alcohol are employed per mole of melamine.  In examples: (1) melamine and formaldehyde are heated to 80 DEG  C. in a solution adjusted to pH 7.7-8.0 with barium p  hydroxide.  When a sample retains its clarity when cooled to 25 DEG  C. and is completely miscible with cold water, the pH is adjusted to 7.7 with further barium hydroxide and most of the water distilled off.  Butanol is then added and the mixture heated whilst passing carbon dioxide through it, the butanol distilling off being returned to the reaction vessel.  Heating is continued till the product is completely miscible with xylene; (2) and (3) as in (1) but using strontium or calcium hydroxide instead of barium hydroxide; (6) as in (1) but using isobutanol instead of n-butanol; (7) as in (1) but using amyl alcohol instead of butanol and stopping the etherification when the miscibility with xylene reaches a maximum value; (4) and (5) melamine and formaldehyde are heated to 80 DEG  C. in a solution adjusted to pH 7.7-8.0 with barium hydroxide until a sample of the product shows an acetone tolerance of 3.5-4.  After adjusting the pH to 7.7 with further barium hydroxide, most of the water is removed, n-butanol is added and the mixture heated whilst passing carbon dioide through it and returning butanol to the reaction vessel.  Heating is continued until the miscibility of the resin with xylene reaches a maximum value; (8) melamine is condensed with formaldehyde as in example (1). n-Propanol and xylene are added to the condensate and the mixture heated whilst passing a stream of carbon dioxide through it.  The distillate separates into two layers and the upper propanol-rich layer is returned to the reaction vessel.  Heating is continued until the miscibility of the resin with xylene reaches a maximum value.

Abstract: 654,426. Separating achenes from pyrethrum flowers. POTTS, F. C. (Notcutt, L. A.). March 12, 1948, No. 7538. [Class 58] In a method of separating achenes and/or achenes plus florets from pyrethrum flowers the latter are subjected at substantially diametrically opposite regions of the peripheries to substantially radial inwardly directed pressure, the flowers at the same time being caused to rotate about their stem axes so that said pressure is applied successively at all points around the periphery. As shown, the flowers are fed via a shoot 22 into a machine comprising a rotatable disc 33 and a stationary surface 17, either or both of which may have . operative surfaces having a high coefficient of friction, in the form of shallow generally conical concavities, thus forming a clearance between them which is a maximum at the shaft and a minimum near or at the periphery. On rotating the disc 33, the flower between it and the stationary surface is subjected to peripheral pressure whilst rotating, the separated achenes and falling through a screen into a receptacle 28. The surface which may be provided with undulations may be mounted slightly out of accurate rectangularity to the shaft so that the clearance between them may be varied.

Title: Improvements in arc lamps
IPC: H05B31/22
Filed: 1920-12-14
Abstract: 166,627. Railing, A. H., and Angold, G. E. Dec. 14, 1920. Arc lamps.-In a lamp to be used in conjunction with daylight for photography, and having an operating - solenoid A placed at about the level of the arc B and behind a reflector C so as to minimize daylight shadow, a long lever D is linked at one end to the solenoidcore E and at its other end is forked and connected by symmetricallyarranged links to a clutch F acting on the upper carbon J, the holder of which runs on fixed guides K, K<1>. The lever D may work on a knife-edge, and gives a long stroke for a small angular movement. A dashpot M is connected to the lever. Magnetic disturbance of the arc is avoided by having the solenoid A parallel with the carbons and level with the arc. The guide rods K, K<1> are in the same plane as the arc and solenoid, and the reflector C is small, though larger than the solenoid A. As the lamp has a low centre of gravity, it can conveniently be suspended by an eye O or attached. by the lower part of the frame P to a pedestal.

Abstract: 996,753. Automatic speed control. EVERSHED & VIGNOLES Ltd. Feb. 26,1964 [Feb. 26, 1963], No. 7687/63. Heading G3R. In a control system for two phase motor 15, alternating voltages representing error and tachometer signals are applied to amplifier 8 which subtracts the signals and causes a phase displacement of the resultant, whereby the waveform now leads or lags the mains voltage by 90 degrees. This signal is amplified in amplifier 9 which comprises a phase splitter circuit so that the output signals applied to clamping circuits 10,11, are in phase opposition with one another. The circuits 10,11, clamp the negative peaks of the waveforms, and the resulting signals are applied to trigger circuits 12,13, which generate pulses at moments in the cycle which vary with the amplitude of the signals from the clamp circuits. For one half of each cycle, the anodes of silicon controlled rectifiers 1, 3, are at positive potential, a triggering pulse being received from circuit 12, or 13 depending on the polarity of the error signal. When rectifier 1 is fired, the upper part of winding 14 is energized causing rotor 15 to turn in a corresponding direction. During the next half-cycle, rectifier 4 is fired to cause rotation of the motor in the same direction as before. If the difference voltage is shifted in phase, rectifiers 3 and 2 are fired in sequence for reverse operation of the motor.

Title: Magnetic transducing device operating with bubble domains
IPC: H04N5/782
Filed: 1976-02-27
Abstract: 1531802 Magnetic recording head PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Feb 1976 [3 March 1975] 07814/76 Heading G5R [Also in Division H3] A magnetic recording head wherein the magnetic field patterns of coded series of magnetic bubble domains set up in a layer 81 are transferred to a magnetic recording medium 84, e.g. a tape, comprises a shift register or channel 85 which is filled with a succession of coded series of domains by a generator 82 and coding device connected to the signal input, the pattern of each complete series being transferred to the medium 84 periodically using a magnetic transfer field. The transfer field may itself be energized periodically, or the layer 81 may be vibrated to contact the medium 84 periodically, the transfer field being continu. ously energized; in the former case, control of the field may be in accordance with synchronizing pulses of the signal to be recorded, in the case of video information, or in accordance with an edge detector for the medium 84 to ensure that the tracks 90 will be recorded in the same positions relative to the edge. Coding.-The input signal is coded in binary form, the digits of which may be represented by single/paired domains; domains diverted to the left/right of the register (Fig. 1, not shown); domains magnetized in opposite rotational senses; or presence/absence of domains. Domain transport.-Domains are transported using conductors of meander shape (Figs. 1, 7; not shown); they are stabilized by a bias magnetic field. In the simpler arrangement of Fig. 1 (not shown), transfer takes place as soon as the register is full and the domains then proceed to an annihilator at the end of the register or parallel thereto. As shown, however, a domain series is first moved laterally downstream to empty the registers, across a lattice 80 to the transfer zone, where the transfer field is generated by a conductor 87 and the medium 84 is curved to contact the layer 81. The series then proceeds to a second register 86 and an annihilator 83. This arrangement can be adapted for playback by including a bubble detector prior to the annihilator; the recorded information acts to annihilate the lower ones of previouslygenerated domain pairs. The lattice 80 can be hexagonal for compactness. Constructional details.-Coding of information as single/paired domains requires the use of a two-layer device, one layer of which contains a densely-packed lattice of domains, the other of which has domains in certain corresponding positions to form stable, coinciding pairs, Figs. 5, 7 (not shown). Coinciding pairs can be converted into single domains by an increase in the magnetic field, e.g. using a current loop. Preferred materials are partially-substituted yttrium-iron garnets produced by epitaxial growth or by sputtering. Domains are generated by splitting, e.g. using permalloy elements, and can be propagated by a T-I structure.
