Title: Improvements in or relating to electromagnetic switches
IPC: H01H51/32
Filed: 1920-05-18
Abstract: 159,111. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). May 18, 1920. Electromagnetic switches which lock out above or below a prescribed frequency, arc constructed with a lockout winding consisting of a number of copper washers of varied thickness. An E-shaped core 3, to the central limb of which is pivoted an arma- 1 carrying a contact 2, is excited by a winding 4 tending to produce opposed magnetic fluxes in the two outer limbs 9, 11. The limb 9 is provided with a short-circuited winding 5 consisting of a number of copper washers of varied thickness, which virtually increase the reluctance of this limb. Sufficient flux to attract the contact end of the armature is available only when the frequency is less than a certain rate. At higher rates the preponderance of flux in the limb 11 holds the armature open. The point of action is adjustable by altering the tension of the retracting spring 7, the width of the air-gap, and the number of washers on the limb 9. Like apparatus may be designed to respond to currents above a prescribed limit.

Title: Improvements in or relating to the reduction of acidity in synthetic ester lubricants
IPC: C07C69/34
Filed: 1952-06-04
Abstract: The residual acidity of a synthetic lubricant of the complex ester type as defined in the parent Specification is reduced by reacting the complex ester with ethylene carbonate at between 100 DEG  and 300 DEG  C., preferably between 125 DEG  C. and 200 DEG  C. for a period of time sufficient to reduce the residual acidity of the complex ester to a value not exceeding 0.5 mg. KOH/g.  The complex ester is one of the three types defined in the parent Specification and may be prepared from any of the monohydric alcohols, monobasic acids, glycols, and dibasic acids specified therein.  The amount of ethylene carbonate used is generally between 0.5 and 20 per cent by weight of the ester material and any unreacted carbonate may be recovered and recycled to the next batch.  In examples: (1) an ester product obtained by refluxing a mixture of adipic acid, iso-octyl alcohol, 1,4-butylene glycol and xylene (as water entrainer) is heated with ethylene carbonate for 4 hours at 160 DEG  C. to reduce the acidity to the required value; (2) as in (1) the ester lubricant being prepared from adipic acid, iso-octyl alcohol and 1,3-butylene glycol; (3) an ester prepared as in (1) from adipic acid, 2-ethyl-hexyl alcohol and 1,3-butylene glycol is heated with ethylene carbonate at 204 DEG  C. for 4.4 hours to reduce the acidity to 0.04 mg.

Abstract: 944,853. Automatic regulation. F. HIRSCHMANN. March 6, 1962 [April 19, 1961], No.14109/61. Heading G3X. [Also in Division H2] In a supply system for arc welding, the impedance which is in series with the arc is automatically increased in value as the supply voltage rises, and vice-versa. In one embodiment, a saturable reactor 4 is connected in series between the welding supply transformer 3 and rectifier 5. The control winding of the reactor 4 is energized by a magnetic amplifier 11, one winding 13 of which is adjustably energized to set the desired welding current, whilst another control winding 14 is energized from a non-linear bridge 21 responsive to the voltage of the supply mains. The bridge is balanced at the maximum supply voltage envisaged, so that a drop in supply voltage causes the impedance of reactor 4 to be reduced. The reactor 4 may alternatively be controlled by an overcompounded constant voltage transformer or by an over-compounded rotary converter. The reactor 4 may be replaced by thyratrons or corresponding semi-conductor devices, the firing point of which is sensitive to changes in supply voltage.

Abstract: 1396308 Electrodes for lead-acid batteries ELECTRIC POWER STORAGE Ltd 11 May 1972 [11 May 1971] 14258/71 Heading H1B In an assembly of positive and negative leadacid battery electrodes the active material composition of the positive electrodes has a porosity of at least 50% (as defined below) and contains 0À01 to 1% by weight of SiO 2 , and the active material composition of the negative electrodes contains 0À1 to 0À8% by weight ligninderived lignosulphonate material. The percentages by weight are based on the lead content of the compositions. Porosity is defined by the volume of the pores as measured by the volume of mercury which can be forced into a sample of the composition up to a pressure of 5000 p.s.i. divided by the actual geometrical volume of the sample. The preferred silica is " Gasil " (Registered Trade Mark) and the preferred lignosulphonate is " Vanisperse " (Registered Trade Mark). These two materials, conjointly, improve the battery capacity whilst enabling less lead active material to be used in both the positive and negative electrodes. The negative electrode composition may also include barium sulphate. The Specification sets out specific compositions in parts by weight.
