Abstract: 721,533. Reservoir pens. COMPANIA URUGUAYA DE FOMENTO INDUSTRIAL SOC. ANON. Dec. 19, 1951 [Dec. 27, 1950], No. 31433/50. Class 146 (3). In a ball-point pen the reservoir 4, Fig. 13, is of, substantially straight tubular form, open at its rear end or provided with a readily removeable closure 6, and the wall is deformed e.g. as at 25, to provide a local obstruction preventing physical access to the rear of the ball by a wire, needle, or the like, inserted through the rear end of the reservoir. The deformations and air vents 26, can be produced in a heated metal jig when the reservoir is of thermoplastic material. Where the reservoir 13, Fig. 7, terminates in a tapered portion 15 into which fits an extension 17 of the writing extremity 16, the extension can be deformed to provide tongues 19 which prevent the extremity 16 being readily removed. If the reservoir 20 Fig. 9, fits within a sleeve-like part 22, triangular barbs 23 are pressed from the sleeve into the wall of the reservoir to prevent the extremity and reservoir being separated and re-assembled. According to the Provisional Specification, the walls of the reservoir need not be deformed and a porous bronze or other metallic plug is forced into the reservoir. The plug allows air to pass therethrough, but prevents access to the rear of the ball. In a modification, the plug is of metal or plastic material, and is grooved or fluted to allow the passage of air into the reservoir. Specifications 571,698, 573,747, 688,891 and 695,861 are referred to.

Title: Improvements in or relating to electric distant control systems
IPC: G08C19/38
Filed: 1934-11-06
Abstract: 449,901. Distant - control systems. JAPOLSKY, N., 35, Cholmeley Crescent, Highgate, London. Nov. 6, 1934, No. 31870. [Class 40 (i)] In an electric distant-control system of the type wherein a resultant-field type receiver motor is controlled by a transmitter comprising a polyphase winding connected to the receiver and supplied by movable brushes through a commutator, the lag between, the receiver and transmitter which occurs during operation and is dependent upon speed of operation is compensated in the transmitter by varying the transmitter field in accordance with speed of operation. As shown, the transmitter comprises a stationary winding A tapped by the line wires at a, a<1>, a<2> and supplied through a commutator by pairs of brushes DD<1>, EE<1> arranged mutually at right angles and adapted to be driven by a handle T<1>. The current supply from the mains H to the brushes DD<1> is maintained constant by a booster B, J driven by a motor F. The current supply to the brushes EE<1> is derived from a booster B<1> J<1> also driven by the motor F, the field winding being connected in series with an auxiliary generator B<2> which is driven by the handle T<1> and therefore generates an E.M.F. proportional to the speed of operation. Consequently current which is proportional to speed is supplied to the brushes E, E<1> and this current is effective to vary the resultant field in the transmitter so as to compensate for lag. In a modification, the transmitter suprlies the exciting winding of a commutator generator, acting as a power amplifier, the output of which supplies the receiver. In this arrangement the auxiliary generator B<2> is driven by a synchronous motor supplied from the power amplifier. Specification 221,041, [Class 40 (i)], is referred to.

Abstract: 1, 167, 730. Frequency measurement. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd., and P. C. BUTSON. Dec. 19, 1960 [Sept. 18, 1959], No.31964/59. Heading G1U. Frequency is indicated by radial deflection of a spot on a cathode ray tube screen, the direction of deflection corresponding to the frequency. The signal whose frequency is to be indicated is made to set up a standing wave in a waveguide 1 by a short circuit 3. One component of the standing wave is amplitude - or phase-modulated at frequency f, e.g. by supplying an oscillatory signal to a rectifier 2 or to a variable phase shifter. Further waveguides, terminated by short circuits 10, 13 and crystal detectors 9, 12, are coupled to waveguide 1 at points 5, 6 separated by #/8, # being the wavelength of the mean frequency of which indication is required. Detectors 9, 12 supply oscillations, of frequency f and of phase depending on the frequency of the signal to be indicated, to phase sensitive detectors 18, 19 where they are compared with oscillations of frequency f from oscillator 4. The outputs of the phase sensitive detectors therefore depend on the frequency to be indicated and are supplied to the vertical and horizontal deflectors of the cathode ray tube. Each crystal detector may be replaced by two detectors with their couplings to waveguide 1 separated by #/4, their outputs being subtracted. The range of frequencies which will give a unique direction of deflection is greater as junctions 5, 6 are closer to 3.

Abstract: 1,139,043. Automatic control of current and voltage. GENERAL ELECTRIC CO. July 19, 1966 [Oct.19, 1965], No.32418/66. Heading G3R. A voltage regulator circuit comprises a compound connection 16 of transistors 15, 17 connected between an input terminal 10 and an output terminal 12; a differential amplifier 24, 30 associated with a reference Zener diode 20 and providing an error signal in dependence upon output voltage variations as sensed by a voltage divider 26, 28; an amplifying transistor 56 for the error signal which is applied to the base of transistor 15 by way of a biasing transistor 46 having its emitter connected to a Zener diode 48; and an overload protection circuit including a load-current sensing resistor 14, a resistor 40 and a diode 62 connected in shunt across the resistor 14, and a transistor 42 having its emitter connected to the junction between resistor 40 and diode 62, its base connected to the junction between a Zener diode 52 and resistor 54 which shunt the input terminals, and its collector connected over a resistor 44 to the collector of transistor 46 and the base of transistor 15. In normal operation, current flow through transistor 42 and the associated resistor 44 establishes a preselected biasing value for the transistor 15 which is then controlled, by the error signal from transistor 46, to correct for output voltage variations at terminal 12. On the occurence of an overload the voltage drop across resistor 14 renders diode 62 conductive; transistor 42 then becomes negatively biased so that the voltage drop across its collector/emitter path increases to produce a steep increase in the negative biasing of transistor 15, whereby the resistance of the transistor combination 16 is increased to limit the load current to a constant value, the output voltage of terminal 12 then dropping below the value at which it is normally maintained constant. The components of the regulator circuit are thus protected against excessive dissipation. The input voltage at terminal 10 may be derived from the rectified output of an alternator controlled in such a manner that the input voltage is reduced on overload, whereby a further degree of protection is afforded to the regulator circuit Fig.2 (not shown). _________
