Abstract: 1,257,548. Photographic apparatus. GTE SYLVANIA Inc. Oct.3, 1969 [Oct.3, 1968], No. 48779/69. Heading G2A. A percussive type flash-bulb 1 having a depending primer tube 5 is fired by releasing the energy stored in a torsion spring 18 thus causing a striker 20, formed at one end of the spring, to move clockwise (as seen) and strike the tube 5. The firing apparatus is shown in the cocked position. To fire the lamp a striker latch is rotated clockwise thus freeing the striker 20. To release the fired lamp, a cocking lever 24, formed as the other end of the spring 18, is disengaged from a groove 17 in a cocking lever latch 16, and rotated to the phantom line position shown thereby returning the striker 20 to the solid line position shown. To cock the torsion spring 18, the latch 12 is returned to the position shown and the lever 24 rotated back to its solid line position. Since the striker 20 is restrained by the latch 12, twisting of the spring occurs. The apparatus may be mounted in a camera.

Abstract: 1,265,893. Smoke detectors; fire alarms. VIGIFEU. May 5, 1969 [May 7, 1968], No. 22725/69. Heading G1N. [Also in Division G4] General In a smoke detector with series connected reference and analyzing chambers, increase in output signal due to smoke operates a fire alarm, but decrease in signal due e.g. to moisture operates a fault indicator relay. A plurality of detectors may be connected to a central station with their alarm circuits in parallel and fault indicator relay contacts in series. Smoke Detector Fig. 1 The sensor output signal U is amplified by transistors T1, T2 and an increase, due to smoke, above a threshold level determined by R3 and Zener diode Z1 fires thyristor Th1 to operate audible or visible signalling appartus 8 and local lamp L1. (T 1  is an F.E.T. for impedance matching). Reduction of signal U, due to e.g. moisture, releases relay 5 to indicate fault at 8 and light L1. (diode D1 isolates alarm line 9). In a modification Fig. 2 (not shown) the thyristor is replaced by a second set of contacts on relay 5 operative at a predetermined value (greater than the normal current which operates contacts 6). Central Station arrangements Fig. 3 Parallel connected alarm circuits energized from sources 12, 13 are connected to relay S 2  and loaded by an end-of-line resistor 27 so that its contacts float (both open). Alarm signal closes "fire circuit" contact 16 and a decrease or open circuit closes fault signal contact 17. The detector fault relays are series connected to relay S3 having a contact 15 in parallel with contact 17 in the fault signal circuit.

Abstract: 1325342 Dressing fish &c V J EVICH 26 Aug 1970 41105/70 Heading A2U [Also in Division G3] Mechanism for dressing away a layer of predetermined thickness from an irregularly shaped article, e.g. a fish or fish fillet, conveyed past a dressing station comprises an adjustably supported power-rotated dressing roll mounted for swivelling movement of its axis in a plane crosswise of the path of advance of the article whereby it can adjust itself to changing transverse contours of the article. The invention also relates to servo-control of the position of a power-driven dresser in response to movement of a sensor contacting the surface of an article being dressed. In the apparatus described, pieces of fish carried from left to right by a conveyer 13 are dressed by a number of rolls 27, 28 on arms 14 which are pivotally mounted at 20 on a frame 11. Each roll. which has stiff bristles to remove a layer of fish, is positioned by a servomotor comprising a cylinder 44 pivotally attached at 45 to the frame 11, and a piston 48 biased to the retracted position by a spring 53 and connected by a member 49' to the arm 14. Anti-friction bearings 15, 16 allow the arm to swivel about its longitudnal axis to enable the roll to position itself to suit the contour of the fish, the arm and roll being biased to a neutral position about this axis by tension in a drive belt 30 passing over pulleys 31. When a piece of fish approaches the dressing station it first engages a master-control spring 75 which is deflected to engage, a sensing shoe 93 pivotally mounted at 92 on the free end of a servo control spring 88. Continued deflection of the spring 75 then causes the spring 88 to close an adjustably mounted bleed valve 66 resulting in an increase of air pressure in a conduit 57 which is transmitted through a liquid reservoir 55 to the space below the piston 48 to cause the latter to displace the arm and roll. As the fish reaches the shoe 93 it lifts it clear of the spring 75 so that the servomotor is then controlled directly by the shoe acting through the spring 88, and the spring 75 is operative, through adjustable links 78, 95 and bell-crank 81, to orient the shoe about its pivot 92 toadapt it to the inclination of the surface of the fish.

Abstract: 1327081 Light guides; microscopes VANZETTI INFRARED and COMPUTER SYSTEMS Inc 21 July 1970 [29 July 1969] 24701/70 Heading G2J [Also in Division G1] Thermal radiation emitted from the junction of a semi-conductor device during its operation is picked up by an optical fibre device to be detected photo-electrically to give information as to the operating characteristics, e.g. uniformity current crowding and voids, of the device. The signal applied across the junction of device A by means of source 2 and bias 9, Fig. 1 (not shown) results in a recombination effect producing thermal emission, whose wavelength is a function of the material and which is dependent on the distribution of the input signal along the junction. Apparatus and modifications. The basic apparatus comprises a stereo microscope provided with an adjustable mount 3 for the material 1, by which the point of interest can be viewed and aligned with the end of optical fibre light guide 4 which is coupled to detector 5, sensitive to infrared, which feeds control circuit and display e.g. an oscilloscope, or recorder 7. In Figs. 2 and 3 aiming of the light guide on the spot of interest is aided by viewing the material, through a guide which is provided with a central fibre reserved for the detector. The top end of the fibre bundle is either branched (Fig. 2) or has the detector mounted centrally thereon (Fig.3). In an arrangement which allows changing of the detector fibre to suit measuring requirements, Figs. 6, 7 a joint between two fibres is provided, with a bellows arrangement to permit adjustment, the upper fibre being of layer diameter and feeding the detector which is enclosed in a Dewar flask for cooling. In order to monitor particular wavelengths of emitted thermal radiation, a filter may be inserted in the gap (50) between the two fibres, or elsewhere in the optical path. Further, a modulating device (e.g. using an electromagnetically induced rotation of the polarization plane) may be inserted in the gap (50) or elsewhere in the radiation path so as to provide a reference level. Optical fibres. The materials chosen for the optical fibres may be glass, quartz AS 2 S 3 , arsenic-selenium-tellurium fibres etc and are particularly transmissive of certain wavelengths. The aperture of the optical fibre is controlled by choice of cladding material. Detectors. These may be an intrinsic germanium device; a silicon device; a photomultiplier. Calibration of the system may be carried out by the use of a GaAS infra-red emitting diode. A plurality of detectors may be deposited on the emit ends of the fibres of the bundle. Specification 1327082 which describes the use of the same apparatus for monitoring thermal bonds, is referred to.

The particular embodiment consists of four sections mounted in alignment on a suitable carrier member. Fig. 1 shows the first section in which the holder members are attached to a bar 22 via flat portions 19 thereof. The flats correctly align the holder members. In the first section the tool bits are aligned but are of increasing radial length so that a groove formed in a workpiece is gradually deepened. The following sections have the tool bits progressively offset so that the initially formed grooves are widened until they meet. The offsetting of the bits may alternate along the length from one side to the other or they may be continuously offset in one direction. In the latter case the direction of offsetting of the four rows would be different to equalize the cutting forces. The arrangement of the offsetting is by differing the position of the flat 19 relative to the pockets.
