Title: Adjustable-position optical system
IPC: G02B15/00
Filed: 1972-06-23
Abstract: 1400218 Optical assembly RANK XEROX Ltd 23 June 1972 29651/72 Heading G2J An optical assembly, e.g. a lens system used in a copying machine, is positioned in one of a plurality of positions by an arrangement whereby the assembly is always moved in the same direction towards a stop, regardless of the general direction of movement required. As shown in Fig. 2, stops 292, 294 are movable into and out of the path of extension 286 of the optical assembly by solenoids SOL18, SOL19. The assembly is driven by screw 267 driven by motor MOTS. When the assembly is to be driven towards a stop nearer to stop 295 than the pre-set position of the assembly the motor drives the screw until the extension 286 contacts the required stop which is placed in its path, which actuates a micro-switch to shut off the motor. When the assembly is to be moved to a stop further away from the stop 295, it is driven in this direction past the required stop, the stop is then brought into the path of extension 286, the motor is reversed, and the assembly driven until it is stopped by the stop when the motor is again de-energized by a microswitch. An electrical control circuit is described to achieve this. This may be applied to the optical system shown in Fig. 1. The lens system is arranged to have three positions, giving three different magnifications. In the middle one, the arrangement is as shown. In another, lens 22 is brought into the optical path, and the whole system is moved towards mirror 262. In the third, lens 23 is brought into the optical path, and the whole system moved towards mirror 263. The lenses 22 and 23 are moved by cam surfaces.

Abstract: 1,036,934. Aircraft undercarriages. DOWTY ROTOL Ltd. July 29, 1964 [July 29, 1963], No. 30011/63. Heading B7G. [Also in Division G3] The load differential between two legs 11, 12 of an aircraft landing gear is reduced (e.g. while cornering or in a side wind) by an actuator 28 (Fig. 2, not shown) which supplies liquid to the more heavily loaded leg and receives it from the less heavily loaded leg. Each leg comprises a piston 19 in a cylinder 15 and the load differential is sensed by a pressure transducer, such as Bourdon tube 64 connected to a potentiometer 66, which transmits signals through a control unit 75 to the split winding 61 of a flapper valve 47. Movement of the valve 47 reduces the flow through one of two nozzles 48, 49 supplied from a pipe 57, and hence increases the pressure at one end of a valve 51, allowing fluid to pass from a supply pipe 45 to one side of a piston 32 connected to the piston 33 of the actuator. In another embodiment (Fig. 3, not shown), the actuator 28 is replaced by a piston fixed to each cylinder 15 and mounted in a cylinder connected to the valve 51.

Abstract: 342,681. Frequency measurements. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Fitzgerald, A.S. ; 1212, Union Street, Schenectady, New York, U.S.A.) Oct. 3, 1929, No. 30022. Convention date, Oct. 4, 1928. [Class 37.] In a system for indicating at a distance the movements of a member, e.g. the readings of an indicating or integrating instrument, for measuring or comparing frequencies or for performing operations at predetermined frequencies, variable frequency derived from the movements &c. control thermionic valves which effect the charging and discharging of a condenser to produce current proportional to the frequency. The system may also be adapted to produce a summation indication of a number of independent instruments. As shown in Fig. 1, an indicating instrument 10 controls a condenser 15, 16 which varies the frequency of oscillation of a valve generator 11 according to the deflection of the instrument. At the receiver a transformer 28 is connected to the line wires 12 and has secondary windings 29, 30 reversely connected to the grids of negatively biassed valves 31, 32 in such a manner that the valves alternately pass current to charge and discharge a condenser 33 from a source 34. As shown the discharge current having a value proportional to the transmitted frequency is measured by a repeating instrument 13. Preferably a condenser is shunted across the instrument to smooth out pulsating current. To indicate the speed of rotation of an integrating meter a commutator adapted to interrupt a direct current source is driven from the instrument shaft and thereby generates pulsations the frequency of which is proportional to the speed. In order to render the repeating instrument independent of voltage variations in the source 34, the instrument may be of the "cross-coil" type, one winding being connected across the source, preferably in series with a resistance, while the other winding is connected in the indicating circuit. The repeating instrument may be provided with contacts in order that different circuits may be closed at different frequencies. Fig. 4 shows receiving arrangements for totalizing independent indications. Independent transmissions are effected over the line wires 12 and are indicated by the corresponding instruments 13 controlled by the valves 31, 32 supplied from the common sources 34, a totalizing instrument A being connected in the charging circuit of both receivers. The Specification as open to inspection under Sect. 91 (3) (a) states that the apparatus may be utilized to control synchronoscopes. This subjectmatter does not appear in the Specification as accepted.
