Title: Improvements relating to vehicle electric lamps
IPC: B60Q1/14
Filed: 1928-03-21
Abstract: 313,995. Lucas, Ltd., J., and Lucas, O. March 21, 1928. Adjusting reflectors from a distance.-A vehicle lamp is fitted with one or more electro-magnets for rocking a reflector and with means which automatically interrupts the current supply to the electromagnets in each movement of the reflector and establishes a circuit in readiness for the production of the neverse movement. The electromagnets may operate impulsively, the movement of the reflector being completed by momentum or by energy imparted by the impulse to a spring or equivalent device, and the circuits may be controlled partly by the reflector, or members connected thereto, and partly by a hand-operated switch or switches. The magnets may be in action throughout the whole or greater part of each movement, one circuit being broken and another established at or near the end of each movement. In the form shown in Fig. 1 a reflector a is pivoted about a horizontal or inclined axis band the lamp socket d carries a rubber or other insulating and cushioning ring f, a metal ring g, and a pair of contacts h which are adapted to co-operate with a pair of contacts i on the plungers j of a pair of electro-magnets k. When the switch arm m is moved the circuit of one of the electromagnets k is completed and its plunger is moved to give a strong impulse to the reflector. The plunger is held, or is returned to its initial position, as by means of a stop or a controlling spring, and the circuit is again broken. The movement of the reflector may be completed by means of a toggle-spring n arranged between the reflector and the lamp casing c, the reflector being brought to rest by one of the contacts k engaging with one of the contacts i. Instead of the electromagnets acting directly upon the reflector, they may act upon an intermediate toggle or other mechanism connected to the reflector. In the form shown in Fig. 2, the lamp socket d is connected by a slotted or other link s to an extension q of the plunger r of a pair of magnet windings t, the extension q carrying a contact bridge u adapted to co-operate with a pair of fixed contacts v, w. The reflector is rocked by means of a switch arm m in a manner similar to that described above.

Title: Improvements in or relating to field excitation arrangements for electric alternators
Inventor: IRVING HERBERT DAN
IPC: H02P9/34
Filed: 1961-03-13
Abstract: 930,129. Alternators ; automatic voltage control. GENERAL ELECTRIC CO. Ltd. March 9, 1962 [March 13, 1961], No. 9058/61. Classes 35 and 38 (4). The D.C. current flowing in the field of a selfexcited alternator is supplied from at least one semi-conductor controlled rectifier and is maintained, when the rectifier is non-conducting, by a rectifier connected with the right polarity in parallel with the field winding. The controlled rectifiers 5, 6 are fired simultaneously during each output cycle by applying a current pulse from resetting magnetic amplifier 7 to the gate of rectifier 5. The timing of the firing pulse, and thus the value of field current, depends on the voltage applied to winding 9 of the magnetic amplifier from transistor 18 and network 20, 21, 22, this voltage being proportional to the alternator output voltage. When the rectifiers are extinguished, during negative half cycles, no field current is supplied but inductive decay occurs in the parallel circuit of the field winding 2 and rectifiers 4 so that a continuous current appears in the winding. When the output voltage is low, e.g. on starting up, field current is supplied through rectifiers 23, 24 and controlled rectifiers 5, 6 are short circuited by means of normally closed contacts 25. Additionally the anodes and gates of each unit are connected through resistor/diode networks 32, 33 and 30, 31 respectively by means of contacts 29. When the output voltage reaches a preset value the contacts open in succession, contacts 25 first to prevent sparking.

Abstract: An emulsifiable composition, suitable for use as a lubricant for textile fibres, comprises a major proportion of mineral lubricating oil and minor proportions each of an oil-soluble naphthasulphonate, an oil-soluble non-ionic emulsifier and a nitrogenous emulsifier which is soluble in oil but substantially insoluble in water.  The naphthosulphonate is a salt obtained by neutralizing petroleum mahogany sulphonic acids with an alkali metal hydroxide, ammonia or an aliphatic amine or alkylolamine. The oil-soluble non-ionic emulsifier may be a monohydric or dihydric alcohol or an alcohol carrying substituents such as ether and/or ester groups, examples of these classes of non-ionic emulsifiers are given.  If desired, a mixture of two or more oil-soluble non-ionic emulsifiers may be employed, and a mixture of glyceryl dioleate and diethylene glycol monolaurate, with or without monoethylene glycol mono-oleate; is specified.  Suitable nitrogenous emulsifiers are primary, secondary and tertiary amines containing at least one hydrophobic group attached to the nitrogen atom substituted isoureas isothioureas guauidines, iminazoles, imidazolines and pyrimidines and salts of such substituted compounds with inorganic or organic acids such as hydrochloric, acetic, stearic or oleic acid.  Examples of the various classes of nitrogenous emulsifiers are given; mixtures of nitrogenous emulsifiers may also be employed.  The emulsifiable compositions may also contain coupling agents or mutual solvents (e.g. lower monohydric alcohols, phenols, glycols, polyglycols and glycol mono-ethers), anionic emulsifiers (e.g. alkali metal salts of higher fatty acids, rosin acids, sulphated alcohols and alkyl aryl sulphonic acids), antioxidants (e.g. 2, 4-dimethyl-6-tert. butyl phenol, N-butyl p-phenylene diamine and tetramethyl diaminodiphenyl methane), antifoaming agents (e.g. silicones, N, N1-distearyl ethylene diamine and N, N1-distearyl hexamethylene diamine), fungicides (e.g. salicylanilide) and corrosion inhibitors (e.g. primary amines, alkyl-substituted oxazolines and oxazoline salts of fatty acids).  If desired, the emulsifiable compositions may be applied to textile fibres in the form of aqueous emulsions.  In the examples, mineral lubricating oil compositions are described containing sodium naphthasulphonates, glycerol dioleate, diethylene glycol monolaurate (with or without "Cithrol A"), 1-b -hydroxyethyl-2-heptadecylene imidazoline, colophony rosin, oleic acid, potassium hydroxide, isopropyl alcohol and water.
