IPC: H01F21/06
Filed: 1959-06-02
Abstract: 848,640. Adjusting radio tuning. TESLA NARODNI PODNIK. June 2, 1959 [June 13, 1958], No. 18803/59. Class 40(5). An arrangement for tuning a group of circuits by means of cones 5, 6 attached to a tuning drive cord 14 is characterized in that both ends of the cord are connected each with one end of a twoarmed lever 3, the centre of the lever being mounted on a tension spring 2. The cord passes over a slide surface 7 situated between the controlled cone and a control spindle 12 over which cord continuously is wound, the length of the cord between the lever and the slide surface being adjustable by means of a screw 10 or 11. Rotation of the shaft 12 causes the lever 2 to rock moving both the cones 4, 5 and separate fine adjustments may be made by adjusting either screws 10 or 11. These screws press resilient members 8, 9 against the cord and thereby change the length of the cord between lever 3 and slide surface 7 giving a fine displacement of the respective cone.

Title: A method for sterilization of heat exchangers and a heat exchanger adapted therefor
IPC: F28F3/08
Filed: 1960-05-27
Abstract: 894,462. Disinfecting heat - exchangers. SEPARATOR A.B. May 27, 1960 [May 27, 1959], No. 18804/60. Class 81 (1). [Also in Group XIII] In apparatus for heat exchange, e.g. -between milk and cooling - liquid, in spaces formed by packing 23, such as lengths of rubber, a chamber for a sterilizing agent such as chloramine solution or steam or a cleaning agent is arranged around all the packings, Fig. 1 (not shown), or a chamber 32 is formed around each packing 23 by an outer packing 31. When bolts or a pressure-plate, Figs. 1, 3 (not shown), for holding together the plates forming the heat-exchanger, are or is loosened, the packings 23 lose contact with adjacent plates because the plates are moved apart by resilient projections at the corners or by the outer packing 31 which is thicker than the packing 23. The sterilizing or cleaning agent can then be supplied to both the liquid spaces and the chamber or chambers surrounding the packings 23 to sterilize or clean the apparatus before use. During operation of the apparatus, when the plates are tightened together, sterilizing agent is retained in the outer chamber or chambers 32 ad kept at a low pressure by a vacuum source connected to the chamber or to a reservoir communicating with the chambers 32. In Fig. 1 (not shown), the liquid inlet and outlet pipes to the heat-exchanger pass through seals in openings in the chamber and its cover. In Fig. 2, packings 30 isolate the openings 28 in a plate 20 by which one liquid passes to the alternate spaces of the heat-exchanger. The sterilizing or cleaning fluid enters through an opening 33 and air evacuates through an opening 34.

Title: Radio telephony
IPC: H04B1/06
Filed: 1924-07-23
Abstract: 225,590. House, W. D. July 23, 1923. Receiving sets, construction of.--A loud-speaking device of the frictional drag type is combined with a wireless rectifymg detector, the whole being mounted in one with a gramophone. A porous disc 13 of plaster of paris or the like is impregnated with an electrolyte such as sal ammoniac alone or in combination with sodium phosphate and bichloride of mercury, the whole having a high electric resistance, and is mounted on a slow-speed shaft 8 driven (like the ordinary turntable shaft 7) bv the motor of the gramophone. To this end it is mounted on a zinc or like plate 12, which also functions as an electrode, and is clamped in position by a nut 15 of material which is preferably electronegative to the electrolyte and to the plate 12, such as nickel, brass or nickel plate. A needle 16, preferably of material electronegative to the electrolyte, is fastened in place of the ordinary gramophone needle and functions as the second electrode, its point running in a circular groove in the disc 13. The gramophone casing holds a tuning coil 28, crystal detector 22, and earth and aerial terminals 42, 41 and the electrolytic amplifier is bridged across a telephone receiver 23, or other inductive resistance, the terminals 26, 27. of which are connected to the electrodes 12 and 16 through a plug-and-socket reversing switch 38 so that the current may be made to flow in the right direction. Alternatively, a valve set may be used. The sound box 5 can be turned so as to serve either for vertical cut or for lateral cut records, and it is pulled downwards by a spring 20. In modifications, the electrolytic block 13 may be mounted directly on the turntable shaft, or an adapter. Figs. 11 and 12, may be provided for use with an ordinary gramophone. In this case the electrolytic device is mounted on a stand 59 having three feet provided with insulation pads 60, and a standard 62. The latter supports a pinion 62<a> integral with a sleeve 63 which has pin-and-slot engagement with a vertical rod 71 the lower end of the latterbeing pinned to an insulating connector 72 adapted to grip the gramophone, shaft 7. The pinion 62<a> drives a gear wheel 65 which pivots on a stud 67 and carries the electrolytic block 13. The electrode or needle 16 is connected by a spring 78' with an insulated plate 79 and terminal 81, and a terminal 82 on the stud 59 is in electrical connection with the plate 12. In a further modification (not shown) the sound box is fixed at right angles to the end of the horn, which carries a terminal and swivels as a whole. In a further modification, the electrolytic frictional device may be replaced by one which operates electromagnetically.

Title: Camera
IPC: G02B7/36
Filed: 1975-05-06
Abstract: 1502787 Automatic focusing HONEYWELL Inc 6 May 1975 [27 Aug 1974] 18888/75 Heading H4D A photographic camera comprises an automatic focusing arrangement in which, the focusing motion of the taking lens and the movement of a spatial light filter which scans an image of the subject to be focused and photographed, said image being focused by a second fixed focus lens, are interlinked. The spatial filter comprises a first portion comprising equally spaced translucent and opaque bars to produce an alternating signal in a receiving photodetector so that an AGC setting in subsequent detection circuitry corresponding to the average image brightness is obtained therefrom and a second filter portion which extends in a plane inclined to the plane of the image comprising pairs of equal width translucent and opaque bars, adjacent bar pairs being of randomly different widths. The subsequent focus detection circuitry is responsive to the peak detected amplitude signal from the detector which corresponds to the infocus position, to actuate a mechanism which stops the filter movement and the taking lens movement when the detected signal is detected to be a maximum, whereupon the taking lens is at the infocus position, the image is focused on to the photographic emulsion and, e.g. automatic exposure of the film may be effected. As described, focusing lens element 5 is movably mounted in lens barrel 1, on externally threaded collar 7, which has also on its lower periphery gear sector 9 which engages a rack of gear teeth 11 on slide plate 10. Transverse movement of slide plate 10 is produced by the action of spring 13, on depression of pin 17. Slide plate 10 may be moved to a cocked position by knurled member 12 or by automatic means, e.g. a motor (not shown). Depression of pin 17 causes movement of slide plate 10 and concomitant movement of focusing lens 5 and spatial filter plate 27. Fixed focus lens 25 brings the image to be photographed to focus in a region through which spatial filter plate 27 moves transversely. Plate 27 comprises a first portion 28 having a low frequency bar pattern, see Fig. 2. This produces in photoelectric detector 26 a signal representing the average brightness level of the scene, and sets the AGC of the associated detection circuitry (Fig. 6, not shown). Subsequent movement of the filter plate 27 through the focusing region of lens 25 produces a high frequency signal in the detector which is then rectified and applied to a circuit containing a diode (47) and capacitor (48) which act as a change of slope direction detector to produce via an amplifier (49) an output when peak amplitude of the detector signal occurs which output energizes a coil (37, Fig. 6, not shown) to actuate brake shoes (33, 34) which freeze the position of slide plate 10 and therefore lens 5 which is now in the correct focused position. In a modification (Fig. 3, not shown) the first spatial filter portion may be inclined to the image plane.

Abstract: 1528667 Moulding slide fastener joining device SOC PRESTIL 7 May 1976 [4 June 1975] 18992/76 Heading B5A [Also in Division B3] A metal or plastics joining device for an "open-ended" slide fastener (Figs. 7, 8) which comprises a male piece 3a and a female retainer 3b on corresponding ends of the tapes 1a, 1b which carry the ions of fastener members is made while the fastener is assembled by moulding the male piece 3a on to one tape 1a and then moulding the female retainer 3b on to the other tape 3a using the previously moulded and cooled male piece 3b as a moulding core, the male piece extending out of the retainer to ensure that it can be withdrawn to separate the halves of the fastener. The male piece 3a is formed with extensions 6 on each face of the tape la to prevent adhesion of the female retainer 3b to the tape 1a during moulding. Alternatively the tape 1a may be coated with release material after moulding the male piece 3a without extensions 6. A ridge 15 on piece 3a forms a locating groove 16 in an extension 12 of the retainer 3b. The extension 12 may be formed by a base piece 17 (Figs. 10, 12), which is premoulded when the male piece 3c is moulded, for incorporation into the female retainer 3d by means of keying projections or a roughened surface. The male piece and the female retainer may be moulded over fastener elements already carried by the tapes.

Title: Mechanism for use in the preparation and assembly of office stationery
IPC: B65H37/04
Filed: 1950-01-22
Abstract: 688,210. Book-binding. HALLEY & SONS, Ltd., J., and HALLEY, A. M. Jan. 19, 1951. [Jan. 22, 1950] No. 19282/49. Class 16. [Also in Group XL (b)] In a machine for bundling, and gumming together sheets of perforated paper the perforating and gumming mechanism is controlled by a photoelectric cell responsive to the sheets. As shown, a bell crank lever 4 following a cam 8 reciprocates a table 3 to feed sheets one at a time to gripping rollers 9 mounted above a highly polished cylinder 10. Light from a source mounted in a housing 11 and reflected to a photo-cell in the same housing is is interrupted by the arrival of the sheet of paper and energizes solenoids 12 and 13. Solenoid 13 forms part of a counting mechanism to be described. Solenoid 12 rocks a lever 18 to lower a perforating wheel into a contact with a hardened lightly polished cylinder 21, the perforating wheel being rotated by gearing on the end of the cylinder. A further light source and photo-cell mounted on a housing 22 prevents de-energization of the solenoids when the end of the sheet passes housing 11. As the sheet leaves the perforating station it interrupts a further beam of light reflected from a polished cylinder 24 to a photo-cell in a housing 25. This cell energizes a solenoid 26 to rock a roller 30 taking glue by way of rollers 71, 72 from a glue pot 29 into contact with the edge of the paper. The leading edge of the paper is detected by interrupting light reflected from a mirror beneath the paper to a photo-cell in a housing 33 so that solenoid 26 rotates and gumming of the polished cylinder as the paper leaves it is prevented. The sheet is then filed between the bottom tails of four helices 57 rotated by gearing 59 rotated by a rack 60 reciprocated by a crank 61 driven from the main machine drive. These helices perform a complete revolution in half a machine cycle so that the damped gummed sheets are spaced in the coils. To prevent gumming of the last sheet solenoid 13 (operated by the cell in housing, 11 moves a detent 39 into engagement with a ratchet wheel 44 so that the wheel moves on one step each time the detent is rocked by a cam 43. Intermittently spaced on a wheel 47 rotating with the ratchet wheel are protuberances 48 which operate a microswitch 53 to break the circuit of solenoid 12 preventing the application of gum to that sheet. The frequency of ungummed sheets depends on the number of protuberances on the wheel 47. The glue used is a thermo-setting plastic and the gummed sheets are "knocked up" after drying and secured together in a heated clamp. The cells 11 to 33 are adjustable transversely to the direction of movement of the sheets so that perforating of sheets below a certain width may be avoided. This is used to permit interleaving of imperforate carbon sheets.

Abstract: 611,605. Washing granular materials. WERF CONRAD, N. V. July 4, 1939, No. 19507. Convention date, Jan 16. [Class 82 (ii)] In the wet separation of solid particles from loose masses in which the latter is fed from a hopper 2 over the impervious bottom of a trough-shaped container 1 hung on links 4, 5 reciprocated longitudinally by an eccentric 8 and rod 9, and provided with a series of discharge zones 20, 21 formed as transverse slots, each zone is provided with small discharge apertures and the head of the liquid in the container 1 above these zones is hydraulically balanced by a counter liquid pressure, pulsations being produced in the liquid in these zones so that a jigging action is produced in the latter. The apertures in the zones may be produced by sharp-edged plates 22, 23 leaving small openings each side or by gratings or perforated plates fitted into the zones. The pulsating action in the zones may be produced by suspending the entire container in a water bath, or as shown in Fig. 3, a pipe 25 is connected by a rubber pipe 26 with a pipe 27 having an upwardly extending part 28 on which is telescopically arranged a tube 29 having an overflow 30 and a water supply pipe 31. Another form of discharge is shown in Fig. 4, the slot being covered by a curved hood 40 leaving a gap 41 and provided with a sheet 22 having gaps in its longitudinal edges and arranged over a perforated sheets 42. Balls 43 supported by the sheet 22 are constantly moving owing to the movement of the container, so producing the pulsating effect required. In another form the sheet 22 may be replaced by a corrugated sheet with recesses at the edge only of the corrugations. To assist in the separation, the container may be provided with a wall 12 and groups of pins 13 and the bottom of the container may be extended upwardly just below the points 20. 21. The links 4, 5 may be of different length decreasing towards the discharge end 3 of the container which may also be provided with an additional discharge at the point 50. The Specification as open to inspection under Sect. 91 also refers to the application of a differential movement or a percussive action on the container. This subject-matter does not appear in the Specification as accepted.

Abstract: 301,101. Davies, D. R., and Metropolitan-Vickers Electrical Co., Ltd. July 25, 1927. Transformers. - In metal - clad switchgear arrangements in which the casing of an oil break switch, such as an isolating or selector switch contains auxiliary apparatus such as a potential transformer, devices for use with such apparatus as a fuse and limiting resistance, are arranged to be disconnected and withdrawn through an opening in the switchgear casing whereby they may be safely handled without putting the switchgear out of service. As shown in Fig. 2 in which a potential transformer 2 is mounted within an oil-filled casing 1 containing an isolating or selector switch the fuse 23 and limiting resistance 24 are mounted on a movable carrier 19 bearing contacts 29 engaging fixed contacts 28. When it is desired to inspect or renew the fuse or resistance the carrier 19 is raised to the dotted position by screw and nut gear 13 operated through bevel gearing 21. The lid 11 of a hood 10 on being opened, enables any replacements to be effected. During the raising of the carrier its contacts are disengaged from the cooperating fixed contacts so isolating the auxiliary devices 23, 24. Arrangements for earthing the carrier in its position may also be provided. If it is desired to test the cable the carrier 19 may be removed from its holder and replaced by a bracket 41 (Fig. 3) carrying an insulated rod 43 terminating at its lower end in a spring contact 44 for engagement with the fixed contact 28 passing to the cable. Thus connection of the cable to external devices may easilv be effected. A second bracket 45 acts as a stop to indicate the correct position of the conductor 43 when lowered into contacting position. Specification 196,369 is referred to.
