Title: Line sawtooth current generators
IPC: H03K4/62
Filed: 1976-01-16
Abstract: 1530661 Converting circuits for TV receivers PHILIPS GLOEILAMPENFABRIEKEN NV 16 Jan 1976 1719/76 Heading H2F [Also in Division H4] In a line deflection circuit of the type described in Specification 1,459,922, e.g. for a T.V. receiver, a switching device such as transistor Trl is connected across a pair of networks each having a trace capacitor Ct and a retrace capacitor Cr and is periodically turned on so as to generate line deflection current in deflection coils Ly. The amplitude of the sawtooth current is modulated, e.g. for the correction of eastwest pincushion distortion, by means of a switching device Tr2 across one of the trace capacitors Ct. As described, the line deflection transistor Trl is periodically turned on by a line oscillator and driver 9. The coils Ly, trace capacitor Ct and retrace capacitor Cr are duplicated at L<SP>1</SP>, Ct<SP>1</SP> and Cr<SP>1</SP> and connected to a diode modulator D, D<SP>1</SP> arranged so that the line amplitude is modulated at field frequency so as to provide east-west pincushion correction but this modulation has no effect on the EHT voltage obtained by diode D1. A voltage proportional to the field current is developed across resistor R1 and fed to an integrator Tr3 which converts it to a parabolic waveform which is fed to transistor Tr4 together with a small proportion of the field sawtooth (for tilt control). Width modulated pulses are provided at the collector Tr4 by means of a line frequency sawtooth from stage 9 fed via transistors Tr6, Tr5. The conduction of the diode modulator D, D<SP>1</SP> is controlled by Tr2 in response to the width modulated pulses so as to correct the east-west pincushion distortion. Tr2 forms a switched mode power supply having its input at the upper side of L4 and its output across C4. The energy from Tr2 is added to that provided by rectifying by D3 the line flyback across L5 and feeding it to the field deflection circuit 11. In Fig. 1 (not shown) the voltage at the junction of D and D<SP>1</SP> is filtered by a further inductor and capacitor and fed via a series switched mode transistor to the upper point of L4.

Title: Improvements in and relating to radiographic apparatus
IPC: G03B42/02
Filed: 1943-02-04
Abstract: 562,497. Radiographic apparatus. SCHALL & SON, Ltd., and HARDING, B. W. Feb. 4, 1943, No. 1881. [Class 98 (i)] The apparatus comprises a carrier for a film or plate large enough to record more than one image, or several juxtaposed smaller films or plates, the carrier being movable between successive exposures away from its operative position, and means for automatically locating the carrier on its return to operative position comprising rotatable stops automatically set by the movements of the carrier into the path of blocks on the carrier so that different areas of film or plate are presented successively in the exposure position. The apparatus may include a fluorescent screen or support therefor to permit radioscopic inspection between successive exposures. As shown, the film or plate cassette is mounted in a frame 1 having a cassette-locking catch 19 and a spring 18 to facilitate removal of the cassette when unlocked. The frame 1 is guided on runners 2 in a protective casing 3 having an exposure aperture 17 in line with the X-ray beam and may be displaced in relation to the aperture by a hand-operable crank pivoted at 7 to the casing 3 and connected by a link 4 to a lug 6 on the frame 1. The automatic locating mechanism comprises a shaft 9 mounted in the casing 3 and carrying a ratchet wheel 10 prevented from reverse rotation by a spring pawl 14 and wheels 11, 12 having stop-teeth adapted respectively to engage stop-blocks 15, 16 spaced along the frame 1. In the position shown,.the left-hand third of the film or plate is in position for exposure, with a tooth of wheel 11 engaging block 15. After exposure, the linkage 4, 5 is operated to move frame 1 to the right, leaving the window 17 free for radioscopic examination; and during this movement a spring pawl 13 on frame 1 turns the ratchet wheel 10 so as to lift said tooth of wheel 11 out of the path of block 15 and bring a tooth of wheel 12 into the path of block 16. Thus, when the linkage 4, 5 is operated to return frame 1 to operative position, the frame is arrested b block 16 with the middle third of the film or plate opposite the window 17 for the second exposure. Thereafter, repetition of this procedure causes further rotation of the ratchet wheel 10 to raise the tooth of wheel 12 also out of arresting position, so that on the final return movement frame 1 is arrested by the left-hand end of casing 3 in position to expose the right-hand third of the film or plate at the window 17. More than three images may be successively recorded by multiplying the number of toothed wheels and stop-blocks. If desired, a spring detent device may be located between the frame 1 and casing 3 to hold the frame more securely in each of the positions in which it is arrested.

Abstract: 675,726. Electric tests. AKTIEBOLAGET BOFORS. Jan. 25, 1951 [Jan. 27, 1950], No. 1956/51. Class 37. [Also in Group XXXVIII] Apparatus for measuring the phase difference between two A.C. signals of the same frequency comprises two phase detectors 2, 9, the first being used to relate the phase of an oscillator 4 of the same frequency with one signal, and the second to determine the phase-relationship between the output of oscillator 4 and the other signal. The first detector 2 gives a control signal when oscillator 4 and the input reference signal at 1 do not bear the correct phase relationship, said signal operating on a reactance valve 5 to correct the phase of the oscillator 4. The signal from 4 is amplified and split at 7 and fed to the stator of a phase-shifter 11 to give a rotating magnetic field, so that a signal is developed in the rotor of 11 whose phase is determined by the position of the rotor in the field, and is compared with the reference signal at 8 in the other phase detector 9, any phase divergence producing a control signal, amplified at 12 and driving a motor 13 coupled to the rotor of 11 to remove the phase difference. Hence, angular movement of the rotor of 11 is proportional to the phase difference in the two A.C. signals.

Abstract: 793,833. Waveguide filter circuits. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Jan. 20, 1956 [Jan. 21, 1955], No. 2023/56. Class 40 (8). [Also in Group XL (c)] An arrangement for coupling two radar sets or other radio-frequency sources operating at different frequencies to a common load consists of a length of line or waveguide 2-3 joining the two sources 10, 11; a further line or guide 4-5 connecting a matching load 13 to the intended load 12. At two points 6 and 7 the lines or guides are connected by 3 db directional couplers and mid-way between the couplers in each of them tuned filters 8 and 9 are arranged to pass energy of the frequency of source 10 and reject energy of the frequency of source 11. Preferably the filters are T. sections of waveguides with the cross-arm of the T in the connecting guides and the branch short-circuited so that their reactance is a minimum at frequency f and odd multiples thereof and a maximum at 2f and multiples thereof; f and the operating frequencies are so chosen that the source 10 is coupled to the output through both directional couplers and the source 11 through coupler 7 only. All the energy is fed to the load in each case and there is no interaction between the two sources. The common load may be a common aerial and it will be seen that where the sources are radar sets, return echo signals reach the appropriate radar. A plurality of coupling arrangements such as that shown in Fig. 1, may be used to link any number of radar sets to a common load, the sets being coupled in pairs and then the pairs being coupled and so on as necessary. Where the number of sets is not exactly 2n (n being any integer) one or more coupling units may be omitted. The coupling of 4 and 8 sets is described (Figs. 3 and 5 respectively, both not shown) and the arrangement of the radar frequencies and filter resonances discussed.

Abstract: 618,593. Wrapping-machines. SAPAL SOC. ANON. DES PLIEUSES AUTOMATIQUES. Jan. 22, 1946, No. 2100. Convention date, Dec. 26, 1941. [Class 94 (i)] A method of wrapping bodies of revolution consists in loosely enveloping the body in a sheet of wrapping material, and smoothing out the material by causing the wrapped body to turn on itself in a pocketlike recess whereby the surface of the body slides frictionally against the surface of the recess while being pressed against it, so that the wrapping is closely applied to the object with a smooth finish. An arm 1, Fig. 1, rotates with a powerdriven shaft 2 and carries a detachably mounted and interchangeable member 5 of hard composition such as fibre, in which is cut a pocket 6 to receive an object 7 already loosely wrapped and brought into position by pincers 8 of a mechanism not shown. The pocket 6 in longitudinal section is substantially of the shape of the object below the median plane thereof, but in transverse section it widens out slightly. During rotation of the arm 1 from the position shown to a lowermost position where the object 711 is delivered to a chute 11, the object is in contact with a lining 9, of sponge rubber or the like, or a stationary member 10, whereby the object is rotated about itself in frictional contact with the pocket 6. If the object is a bottle 12, Fig. 3, the pocket may be in two parts 5a, 5b, the latter resiliently mounted for slight movement relative to the part 5a, to avoid breakage of the mechanism. The object could be placed manually in the pocket 6, and turned thereon by bringing manually into contact with it a rubber covered member moved' backwards and forwards.
