Abstract: 548,443. Frequency stabilization. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 16,1941, No. 8996. Convention date, July 17, 1940. [Class 38 (iv)] [Also in Groups XL and XXXVI] In carrier-wave frequency-modulation systems especially for the transmission of television signals, an extreme frequency is stabilized when the average intensity of the signals varies by means of a circuit which develops a voltage proportional to the amount by which the extreme frequency is exceeded and applies this voltage to frequency determining means to vary the mean frequency of the oscillations to bring their peaks to the desired value. As shown in Fig. 3, an oscillator 2 with a regenerative circuit 12 is coupled by condensers BC to reactance valve modulators 14, 141. The grids and anodes of these valves are coupled by phase shifting condensers 22, 221 and the cathodes are connected by condensers 23 231 to earth. Frequency modulation of the generated signals is accomplished by impressing video signals through a condenser 25 on the grids 18, 181 in phase. The modulated output is transmitted through amplifier and/or limiter stages 20 to a suitable transmitter and also to a limiter 50 leading to a resonant circuit 52 including a diode peak detector 56 having a sloping characteristic C, Fig. 2c. The diode is connected by a time-constant resistance-condenser circuit 62, 64 to the grid 71 of a direct current amplifier 73, the anode of which is connected by resistance 78 to the grids 18, 181 of the modulating valves 14, 141 to produce the desired stabilization.

Patent GB-686256-A (GB)
Title: Improvements in or relating to lubricating greases and thickened oils
Filed: 1950-04-14
Abstract: Particulars are given of the preparation of aluminium isopropylate and secondary butylate, for use in the manufacture of lubricating greases (see Group III).  In an example, degreased aluminium powder is mixed with mercuric iodide and iodine, dehydrated secondary butyl alcohol is gradually added and the mixture is heated on a steam bath for 1.5 hours to remove excess alcohol.  Mercuric chloride is also mentioned as a catalyst. Aluminium isopropylate may be prepared similarly.ALSO:Lubricating greases or thickened oils are prepared by dissolving or uniformly dispersing an alcoholate of a polyvalent metal in a lubricating oil, hydrolysing the alcoholate to form a polyvalent metal hydroxide and removing the non-metallic volatile products of hydrolysis.  Suitable hydroxides are those of silicon, aluminium, calcium, strontium, barium, titanium, chromium, iron, vanadium, magnesium, copper, cobalt, nickel, tin, lead and selenium. Alcoholates referred to are calcium ethylate, aluminium isopropylate and secondary butylates, magnesium methylate, tetraethyl silicate and dimethyl diethyl silicate; alcoholates of higher alcohols such as stearyl alcohol may also be used.  The lubricating oil in which the alcoholates are dispersed may be a mineral, vegetable, animal or synthetic oil.  Synthetic oils mentioned ar those obtained by alkylating aromatic hydrocarbons, such as alkylated naphthalenes; esters of dicarboxylic acids having at least 6 carbon atoms, such as bis (2-ethylhexyl) sebacate; polyalkylene oxides and glycols such as polypropylene glycol; organic phosphates such as tricresyl, trioctyl, tributyl and phenyl-dibutyl phosphates; condensation products of unsaturated ethers with hydrogen sulphide or mercaptans, for example the adduct of hydrogen sulphide and allyl ether; and polymerized wax olefines.  Waterproofing agents, such as hydroxy fatty acids, high molecular weight glycols, monohydric alcohols, amines and fatty acids, soaps, hydrocarbon sulphonic, phosphinic and phosphonic acids, and alkyl halogen silanes, may be added to the greases; examples of such compounds are 12-hydroxy stearic acid, aluminium oleate, glyceryl mono-oleate, octadecylamine, 1, 10-decamethylene glycol, dimethyldichlorosilane and aluminium stearate.  Oxidation inhibitors such as phenyl alpha-naphthylamine and substituted phenols may also be added to the greases.  In an example, an ethyl alcohol solution of calcium ethylate, formed by the action of boiling ethyl alcohol on calcium turnings, is mixed with mineral lubricating oil and water then gradually added.  The mixture is heated to evaporate alcohol and water and the resulting grease contains about 10 per cent, calcium hydroxide.  Specifications 259,431, [Class 91], and 685,146 are referred to.

Title: Improvements in and relating to the production and storage of helical wire springs
IPC: B21F3/00
Filed: 1935-03-25
Abstract: 458,855. Parcelling. HICKS, R. B., Trenance, Friary Road,North Finchley, London. March 25, 1935, No. 9258. [Class 94 (i)] A machine for making open helical springs, particularly those described in Specification 271,774, [Class 108 (iii)], and for placing them on storage bobbins, comprises means for feeding the convolutions of a spring, as it is formed, between the cheeks of a storage bobbin, and means for severing the wire periodically and replacing the filled bobbin by an empty one. The bobbins 11a, Fig. 5, are of known type and each comprises two cheeks 11a1 having inturned flanges 11a2 and central square openings 11a3. The bobbins are placed in rows on a continuously driven belt conveyer lld, Fig. 2, and a row is tipped periodically into an inclined shoot 11g which leads into a hopper 11b. The lowermost bobbin in the hopper is retained by a plunger 11o which with two other plungers 11n, 11p is retracted periodically by a cam 11 on a cam shaft 10. When this movement takes place, a filled bobbin is released and a new bobbin falls from the hopper on to the lowest plunger 11p. A rotating shaft 12b :is then advanced by a cam 12 on the shaft 10 until the squared end of the shaft enters the square openings 11a3 in the bobbin. The speed of rotation of the shaft is controlled by a cam 13 which moves a friction wheel 13b. splined on the shaft, over the face of a friction disc 13a on the main driving-shaft 20. A cam 14, Fig. 1, controls the feed of the wire from a supply spool (not shown), between feed rollers 14a, 14b to and through a coilforming device of known type. The coil spring so formed passes along a cylindrical support 14c to be fed through a guide 14d between the cheeks of the rotating bobbin. Periodically the cam 14 releases the pressure between the feed rollers 14a, 14b to stop the feed of the wire, and when this takes place, the coil is cut near the guide 14a by shears 15f, 15g operated by a cam 15. During the cutting stroke, the shaft 12b, is retracted partly to stop the rotation of the bobbin. After the wire has been cut, the shaft 12b is advanced to rotate the bobbin again to wind on the portion of wire still projecting from the bobbin. Next, the shaft is retracted fully and the filled bobbin is released and replaced by a now one. In the event of the hopper becoming empty, or a filled bobbin not being released, the motor is stopped. For this purpose, the filled bobbin falls on to a pivoted flap 17e, which forms part of the circuit of the driving-motor. The circuit must be completed through an empty bobbin on the hopper the filled bobbin on the flap 17e.

Abstract: 622,787. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 9, 1947, No. 9411. Convention date, June 20, 1942. [Class 40 (vi)] [Also in Group XXXIX] In a multi-channel carrier system with automatic gain control at repeater stations, two parallel paths carry the signal currents to the input of the repeater, only one of the paths including means controlled by an auxiliary current for adjusting the signal level. As shown in the Figure, these two paths may constitute feedback paths A and B for the repeater 1. Path A, which includes an attenuator and a buffer amplifier introduces a positive feedback voltage proportional to the output voltage of the repeater 1, while path B, which includes a variable mu tube 7, controlled by the pilot current derived by filter 8, amplifier 9, and rectifier 10 from the output of the repeater, in such manner that its amplification factor is inversely proportional to the pilot voltage, and attenuation and phase correctors 11, introduces a positive feedback which increases as the output level of the repeater falls. This rate of increase is such as to maintain the repeater output level substantially constant.

Title: Improvements in and relating to the impregnation of wood
Inventor: HENRIKSSON STEN TYCHO
IPC: B27K3/08
Filed: 1952-04-16
Abstract: 727,041. Treating wood. BOLIDENS GRUVAKTIEBOLAG. April 16, 1952, No. 9563/52. Class 140. In a process for impregnating wood in which the wood and the impregnating liquid surrounding it are subjected to pressures alternately greater and less than the pressure of the air within the wood, each change from high to low pressure and back again is carried out substantially instantaneously, i.e. within a period of a few seconds. The pressure of the air within the wood may be increased by pretreatment with compressed air, or by use of a heated impregnating liquid. A complete cycle consisting of one high-pressure and one low-pressure stage may last for 10 seconds up to 10 minutes. Formulµ are quoted from which may be calculated the total number of cycles required, which may be from 5 to 500, the length of the cycle, and the relative length of each pressure stage in a cycle at different phases of the impregnation. The wood is placed in a vessel 1, Fig. 7, which is then closed. Impregnating liquid from tank 2 is pumped into the vessel by pump 3 while air escapes through a valve 8. When the vessel is full, valve 8 automatically closes as a spherical sealing member 18, Fig. 8, floats on the liquid and is pressed against an upper sealing surface 19. The liquid pressure rises until it reaches a known value, after which liquid passes through pressure relief valve 11, Fig. 7, and returns to the tank. The electric motor 4 driving the pump 3, which is a reversible pump such as a gear pump, is then switched into the control of an automatic, current reversing device, so that impregnating liquid is alternately withdrawn from the vessel 1 to produce a subatmospheric pressure, and supplied to it to produce a high pressure. Alternatively, non- reversible pumps, e.g. centrifugal pumps, may be employed, and reversal of flow obtained by valve devices, or two pumps may be used, one serving as a suction pump and the other as a pressure pump. The current reversing device may be controlled by amplified impulses from a photo-electric cell which receives a light beam that is periodically interrupted by opaque areas on a film web traversing the beam at constant speed. Alternate transparent and opaque areas on the film web correspond to the alternate low and high pressure stages.
