Title: Monitoring of incident electromagnetic radiation
IPC: H04N3/09
Filed: 1972-11-03
Abstract: 1429778 Infra-red viewing system CARL ZEISS-STIFTUNG 3 Nov 1972 [5 Nov 1971] 50862/72 Heading H4F An optical system includes a device for detecting incident infra-red radiation, means for moving this device along a predetermined path in or adjacent an image plane of the optical system, means for moving a light source providing visible radiation synchronously with the movement of the detecting device along a predetermined path in a plane representative of the image plane, and means responsive to the detecting device for adjusting the output of the light source in dependence upon the infrared radiation intensity incident upon the detecting device. An application of such a system is in target location. In one embodiment (Fig. 1) an infra-red detector 2 is fixed to a mounting 3 which by means of drive means 4 can repeatedly scan the image plane 1a of an image production system 1 in the direction 5-5<SP>1</SP>. The target is observed with the aid of a T.V. camera tube 8 and receiver 9. Locational information obtained by means of detector 2 is represented relative to the T.V. receiver 9 by means of a movably mounted light source 11 controlled by an amplifier 10 which serves to adjust the brightness of the light source 11 in dependence upon the intensity of the image at detector 2 of a heat source in the target area. The movement of light source 11 is controlled by means of a displacement transducer 7 coupled to the drive means 4 and is operated synchronously with the movement of detector 2. By selecting for the light source a phosphor differing from that of the T.V. receiver screen, the thermal location can be clearly indicated in relation to the observation image content. Alternatively it is also possible to electronically gate the thermal signal into the T.V. image content. In a further embodiment (Fig. 4), the image field 25 is scanned wholly or partly by the receptive ends 24 of a multiple radiation conductor 26 (e.g. fibre-optic conductor or waveguide) which are arranged to move in concentric arcs about axis 28. A plurality of infra-red detectors 27, one for each radiation conductor 26, are fixed or moved together. By means of amplifiers 29, signals commensurate with the radiation received by conductors 26 are fed to a plurality of light sources 30 whence light is conducted via a multiple radiation conductor 26<SP>1</SP> to a data interpretation surface 25<SP>1</SP> provided in the path of the beams of the observation system.

Title: Frequency divider
IPC: H03B19/14
Filed: 1969-10-24
Abstract: 1,243,590. Frequency dividers. SOC. SUISSE POUR I'INDUSTRIE HORLOGERE S.A. 24 Oct., 1969 [25 Oct., 1968], No. 52321/69. Heading H3T. A divider consists of two switches such as F.E.T.'s T 1 , T 2  connected in series with one another and with an impedance such as an inductor T r  and capacitors C 1 -C 4 , and a D.C. supply P, one F.E.T. T 1  being made conductive at the frequency to be divided (from an oscillator O) and the other F.E.T. T 2  being made conductive at the divided frequency by a signal derived at b from the output. T 1  conducts each time the input signal V 1  (also Fig. 4, not shown) exceeds its threshold (V T1 ); and T 2  conducts each time the voltage at b (V 2 ) exceeds its threshold (V T2 ), the period (t f ) for which this occurs being arranged to be substantially equal to the period (T) of the input signal (V 1 ). The inductor Tr is tuned by the capacitors C 1 -C 4  to the required output frequency which is <SP>1</SP>/ 6 the input frequency in the example. The capacitors C 1 , C 2  form a potential divider which provides the T 2  gate control voltage at b from the output voltage at X; and C 3 , C 4  form another potential divider which makes a further F.E.T. T 3  conduct, thereby holding the junction, a of R 1 , R 2  positive and permitting operation of the overall divider. For initial starting, T 3  is off and the points a, b are held negative by R 1 , R 2  to make T 2  conduct, so that it oscillates until sufficient output voltage is built up to turn off T 3  and permit divider action to occur. The block D represents successive stages. In a second embodiment (Fig. 5, not shown), C 1 , C 2  and R 1  are replaced by a secondary winding t 2  for the inductor T r  to provide the gate control voltage for T 2 .

Abstract: 1,097,370. Railway vehicle undercarriages. MIDLAND-ROSS CORPORATION. Dec. 9, 1965 [Dec. 28, 1964], No. 52339/65. Heading B7L. A railway vehicle bogie comprises a side frame 5, Fig. 2, and a bolster 20 interlocked therewith in the transverse horizontal direction of the bogie by wedges 36 biased by springs 60, the wedges having flat side walls (37), (37a), Fig. 3 (not shown), and occupying pockets 29 in vertical columns 15 of the side frame and also occupying recesses (74) formed between a pair of vertical elongate lugs (70), 71 on each side of the bolster, at the end thereof, the columns having guide surfaces 18 flanking and immediately adjacent the associated wedge and of substantially greater vertical length than the lugs (70), 71 which are opposed to the surfaces 18 at a small clearance therefrom, wherein a bridging element 95 joining the side walls 23, (23a) of each column above the bolster projects into the bolster receiving opening 16, and limits the upward movement of the associated wedge 36. When the wedges are in their uppermost positions an upper edge in each case abuts the bottom face of the element 95 and the wedges still retain the bolster interlocked in the side frame 5. When the wedge is moved to this position, Fig. 6 (not shown), e.g. when a spring 60 is broken or when it is desired to disassemble the bolster and sideframe, the wedge tip 45 still overhangs the bolster opening and defines an enlarged portion 130 of the bolster opening 16. After removing the bolster spring group 28 the bolster may be lowered into alignment with the portion 130 for removal from the side frame. Tilting of the wedge 36 in the pocket 29, in the upper position of the wedge, is prevented by stop ribs (110), (110a), on the pocket side walls or by a stop (120), Fig. 7 (not shown), projecting from the rear inclined wall 24 of the pocket. The elements 95 reduce the span of the sideframe compression member 7 over the bolster opening and thus strengthen the frame.

Abstract: 1464786 Carpet stretchers ROBERTS CONSOLIDATED INDUSTRIES Inc 10 Dec 1974 [26 Dec 1973] 53302/74 Heading A4X A carpet stretcher has telescoping tubular members controlling movement between a head and butt end comprising outer and inner members 13, 17; a pair of shoe members 30 radially moveable into and out of engagement with the inner surface of the outer member 13; and a wedge unit 24 rigidly connected to the inner member 17 and coupled to the outer member 13 to prevent rotation but permit longitudinal movement relative thereto; the wedge unit 24 being longitudinally moveable between the shoe members 30 in one direction i.e. to the left to move the shoe members 30 outwardly into locking engagement with the outer member 13 and in an opposite direction to permit the shoe members 30 to move inwardly out of said locking engagement. As shown, outer member 13 is connected to a head 11 with carpet engaging pins 12 and inner member 17 is connected to a knee kicker pad 16. A carpet stretching leftward force exerted on pad 16 tends to move the wedge unit 24 to the left, which tends to move the shoe members 30 to the right and outwardly into locking engagement with outer member 13  thereby preventing further leftward movement of member 17. On rotating a trigger 37 anticlockwise, a push-rod 36 and release member 33 are moved to the left and move the shoe members 30 to the left, against the bias of springs 41, out of locking engagement with member 13. To increase the spacing between head 11 and butt member 15, member 15 is pulled to the right. This tends to move the wedge unit to the right out from between the shoe members 30 and permits the shoe members 30 to move longitudinally and inwardly out of locking engagement with member 13.

Abstract: 1372086 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1971 [21 Nov 1970] 53609/71 Heading H1K The channel region of an IGFET is formed in a portion of a region 6 from which out-diffusion of characteristic impurity has been effected into an atmosphere of reduced pressure so as to provide a net impurity distribution in the region 6 having a zone 10 of maximum concentration at a position beneath the semi-conductor surface. The source and drain regions 8, 9 (of the opposite conductivity type) may be formed (as shown) entirely within the outdiffused portion or may be formed to be partially within it. The structure of Fig. 2, is formed by the growth on a P-type silicon substrate of an N- type epitaxial layer 3 into which boron is diffused to provide region 6 and isolation walls 18. Boron is out-diffused from region 6 through the original mask for in-diffusion (though in variants the entire surface of region 6 may be exposed) into an evacuated enclosure which may contain a source of undoped silicon to inhibit loss of silicon from the surface. A complementary IGFET and a bi-polar transistor are provided in respective isolated islands of the epitaxial layer. Figs. 10, 13, and 14 (not shown) depict structures formed in substrates of one conductivity type (and not having an epitaxial layer formed thereon) and having respectively an IGFET formed in the outdiffused portion of a surface region of a second conductivity type and a complementary IGFET formed in an adjacent part of the bulk; three IGFETs of the same type each formed in respective out-diffused portions of a single surface region of opposite conductivity type to the substrate; and a single IGFET formed in the out-diffused portion of a surface region and a bi-polar transistor formed in the bulk which it utilizes as its collector region. In the structure of Fig. 10, the IGFET 8, 12, 9 in the outdiffused portion 11 is complemented by an IGFET using the surface region 11, 6 as source and having a gate 41 and drain 40. It is not necessary for the region to be out-diffused to be provided by in-diffusion; the initial region may be formed by ion-implantation..
