Title: Improvements in and relating to apparatus for applying sighting corrections to guns
IPC: F41G5/04
Filed: 1947-04-05
Abstract: 647,473. Applying sighting corrections to guns. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. April 5, 1947, No. 9241. [Class 92 (ii)] [Also in Group XXIX] Sighting corrections are applied to a gun by a mechanical differential, comprising for instance a lever 3 pivoted at 4 to a main lever 1, of which one element is coupled at 6 to a sighting correction computer 7 and the other element 3 is coupled to a double acting hydraulic plunger 13 for applying sighting corrections to the gun, the differential movement of the differential being applied to a hydraulic valve 19 which controls the supply to the plunger of pressure fluid from a hydraulic accumulator 22. Upon movement of the plunger 13 a rack 14 causes a pinion 15 to apply a corrective movement to the gun, a further pinion 16 serving to impart a negative movement to the sight so that the latter remains on the target.. In operation, if say the computer moves the end 5 of lever 3 to the left, then since the end 8 of the lever is held fixed by the plunger 13 a rocking of lever 1 results. This actuates the valve 19 which causes the plunger to move to the left to move the end 8 of lever 3 to the right until lever 1 moves to close the valve 19. Specification 647,472 is referred to.
Patent GB-648625-A (GB)
Title: Improvements relating to servo systems
IPC: G05D3/14
Filed: 1948-04-02
Abstract: 648,625. Follow-up systems. FERRANTI, Ltd., and TAYLOR, M. K. April 2, 1948, No. 9279. [Class 40 (i)] [Also in Group XL (c)] In a follow-up control-system the angular position of the input shaft controls the frequency of an oscillator 9, feeding a T-attenuator network 14, 15, 16, having its cut-off frequency controlled by the position of a servo-driven output shaft, which varies the mutual coupling in the series arm. Lack of positional correspondence (i.e. attenuator cut-off differs from oscillator frequency) allows an error signal to pass to amplifier 17 feeding one field 20 of the . servo-induction motor 21. 'The other field 22 is fed directly from the oscillator. Since there is substantially 90 degrees lagging leading phase shift between the attenuator input and output voltages just above and below the cutoff frequency, Fig. 3 (not shown), the motor runs in a direction to maintain correspondence. The phase-shift/frequency characteristic is improved by feeding the error signal through a valve amplifier to increase the circuit input impedance, Fig. 4 (not shown). The oscillator frequency may be determined by a similar attenuator network (see Group XL (c)), so that the input and output shafts have the same position/frequency characteristic. Alternatively this characteristic may be obtained by causing the oscillator 85 to be servo driven to follow the cut-off frequency of an attenuator 80 controlled by the input shaft 8. The error voltage is amplified at 81 to operate the twophase servo induction motor 82, and the required frequency taken off at 86, Fig. 7. The attenuator network may alternatively comprise series capacitors and a shunt inductor.

Abstract: 580,973. Sextants; sighting clinometers. EVERITT, P. F., HUGHES, A. J., and HUGHES & SON, Ltd., H. March 24, 1939, No. 9329. [Class 97 (ii)] An additional member which reflects light from the luminous body observed on to the artificial horizon or other datum is coupled to the main sighting device so that the datum is illuminated whatever the position of the observed body.

Abstract: 737,209. Coupling rollers. TAKITA, S. April 7, 1953, No. 9453/53. Class 80 (2). [Also in Group IX] A sectional roller has each section formed with an axial cavity at one or both ends, each cavity being provided with longitudinally extending grooves for engagement with splines on a spigot on an end of a coupling member or of an adjacent section, allowance being made for slight rotational play between a section and an interengaging spigot. Where a separate coupling is employed, splines 15 are formed at both ends of the coupling to mate with grooves in cavities 12 in two roller sections 11. The grooves are slightly wider than the splines 15 to allow a clearance with the object, it is stated, of reducing vibrations in the roller. Instead of a separate coupling, each section 11 may be provided with an extension formed with splines 15.

Title: Improvements in compressed air blow-out circuit breakers

Abstract: 564,950. Cras - blast switches. ALLMANNA SVENSKA ELEKTRISKA, AKTIEBOLAGET. June 15, 1943, No. 9518. Convention date, May 29, 1942. [Class 38 (v)] The supply of blast-gas to the breaking gap is reduced by the movable contact in the open-circuit position. Opening of a valve 17 admits the gas to an orifice 14 by way of the space between an outer cylinder 13 and the cylinder 5 containing the operating piston 6 of the movable contact 8. Simultaneously with the opening of valve 17, a three-way valve 15 is opened to admit gas below piston 6, the valve 15 being then operated to exhaust the space below 6 to atmosphere and allow the contact to open, as described in Specification 564,949, the resulting blast through the nozzlecontact 9 extinguishing the arc. In the open position, contact 8 almost closes the opening 14 to cut off the supply except for a quantity sufficient for preventing re-ignition, a buffer 11 cushioning the opening impact. In reclosing, the contact 8 is opened prior to closing the isolator 2. Specification 551,222 also is referred to. The Specification as open to inspection under Sect. 91 states also that throttling may be effected by a member connected with the movable contact. This subject-matter does not appear in the Specification as accepted.

[Also in Division G1] In a spectrometer in which the input and output slits are replaced by grid-like members having alter - nate zones of different optical properties, e.g. transparent and opaque, the zones are formed by concentric rings divided into equal sectors e.g. divided into two, by a diameter as shown in Fig. 2. In passing radiation 29, into a spectrometer, Fig. 3, having such grid-like members 28, 21, the opaque zones of member 21 being reflective, collimating mirrors 31, 23 and dispersive prism or diffraction grating 25, the image of member 28 is only superimposed on member 21 for the wavelength corresponding to the setting of the dispersive system 25 and so by rotating one of the members 28, 21, at a constant speed and passing the output current from detector 33 through an amplifier 40 tuned to the frequency corresponding to the rate of rotation, the output signal is indicative of the quantity of radiation conveyed at the wavelength to which the dispersive system 25 is adjusted. In a modification in which the member 28 works by reflection instead of by transmission, mirror 30 is omitted and the beam passes along the dotted path. The member 28 or 21 which is rotated is produced by photographing a large-scale drawing so that the boundary lines of the rings are perfectly circular and then the other member 21 or 28 which is fixed is obtained by photographing the first member through the spectrometer. In a further form Fig. 10 (not shown) a double beam spectro-photometer is provided with the grid-like members (107, 116).

Metal sheets are straightened by stretching whilst restraining movement normal to the surface of the sheet to prevent buckling. The sheet 10 is gripped by self-tightening stretching heads 13, 14 comprising jaws having eccentric projections (16, Fig. 3) and stretched by force exerted on the head 14 by an hydraulic piston and cylinder 27. Movement normal to the surface of the sheet is restrained by slabs 11, 30, the upper slab 30 of which may lie directly on the sheet 10 or may be spaced from it by screws (35), Fig. 2 (not shown). An arrangement for lifting the upper slab 30 clear of the machine (Fig. 2) comprises an hydraulic ram (34) which lifts the slab 30 through a pivoted arm (33). The slabs may each be formed in a single piece or may be formed by assembling short slabs to the requisite length for the sheet to be stretched. The slabs may have plane surfaces to form flat sheets or may have curved surfaces to stretch materials with a curved cross-section. In another embodiment (Figs. 4 and 5) the slabs are replaced by a trellis formed of girders 36 and beams 37. In another embodiment (Fig. 6) the sheet is restrained by a plurality of rollers (50, 51) and the sheet is stretched by clamping it to two rollers (54, 55) one of which is rotatable to tension the sheet.
