Title: Capacitance transducers
IPC: G01L9/12
Filed: 1975-02-05
Abstract: 1524981 Microphones UNITED KINGDOM ATOMIC ENERGY AUTHORITY 3 Feb 1976 [5 Feb 1975 3 Sept 1975] 4964/75 and 36226/75 Heading H4J A capacitance transducer, such as a microphone, comprises a prepared end (Fig. 4 of Cognate 4964/75) of metal sheathed mineral insulated cable. The prepared end comprises a flattened intermediate region of the cable, the region housing a tubular conductor 5 which forms an extension to one end of a solid conductor 2 of the cable, the tubular conductor being electrically insulated from the sheath 3 with mineral insulation 1 and the end of the cable being closed. In producing the transducer, the insulation 1 and conductor 2 are drilled out (Fig. I of Cognate 4964/75) from one end of a 3 mm. diameter stainless steel M.I. cable to a depth of approx. 25 mm. A centring tube (T) is used to guide the drill (D) and thereby prevent sheath damage. Further insulation 1 is removed by a tubular reamer to expose approx 5 mm. conductor 2 and a tubular conductor 5 is threaded on and crimped to the conductor 2. The tubular conductor 5 is also necked circumferentially so that it can be subsequently snapped off at a point 4 mm. from the open end of the sheath. Next the annulus bounded by tubular conductor 5 and sheath 3 is filled with magnesium oxide and consolidated with a tube. When the filling has reached the necked portion of tubular conductor 5 the outer end of the tubular conductor 5 is snapped off. The end of the cable is next pressed flat between brass blocks 8, having radiused corners 9, to flatten the sheath 3 and conductor 5. The end of the cable is filled with insulation, the assembly is dried out at approx. 200‹C. and the end is helium purged. A plug 10 is inserted at the sheath tip and the assembly is leak tested. In an alternative arrangement, Fig. 1 of Cognate 36226/75 a similar process is carried out with an M.I. cable having twin conductors 2, but the exposed ends of the conductors 2 are twisted together and a tubular conductor 5 is threaded on to the twisted ends 2. The twisted ends of the conductor provide a thermocouple hot junction 11 and the device also acts as a microphone. A temperature measuring instrument 17 (Fig. 2) is connected to the two leads 2 via a connection box 13 and the sheath 3 and one of the conductors 2a are connected to a microphone charge amplifier 14 by leads 15.

Title: Improvements in or relating to locks
IPC: E05B29/00
Filed: 1939-02-15
Abstract: 525,094. Revolving barrel locks. BIEMER, H. Feb. 15, 1939, No. 5015. [Class 44] In a revolving barrel lock having plate tumblers 2, the tumblers are prevented from falling out of the barrel during assembly and on removal of the key by means of rods extending through apertures in the tumblers. As shown, the rods 3 extend through the key-receiving apertures of the tumblers and are of such cross-section as to form between them a guide for the key-bit. The rods may be of other cross-section and disposed through separately formed apertures in the tumblers. Instead of extending completely through the barrel, the rods may leave a gap at their rear ends through which the tumblers may be introduced, the gap being afterwards closed by a plate. Alternatively, the rear end-plate of the barrel may be detachable to allow insertion of the tumblers. The rear end-plate may have a recess shaped to receive the end of the key-bit.

Title: Improvements in or relating to television systems and the like
Filed: 1931-02-18
Abstract: 373,196. Television. BAIRD, J. L. and BAIRD TELEVISION, Ltd., 133, Long Acre, London. Feb. 18, 1931, No. 5134. [Classes 39 (i) and 40 (iii).] In television, a three-dimensioned object 2, Fig. 1, at the transmitter is separately analysed from two directions substantially at rightangles to obtain stereoscopic reproduction. A scanning system 4 sweeps a light spot over the object, cells 6 receiving reflected light and generating the picture impulses. Lenses 10, 101 project images of the sides of the object on the banks of cells 81 .. 86, 811 .. 861 located one on each side of the object, so that the scanning beam thus causes illumination of one or other of cells 81 .. 86, 811 .. 861 to give an indication of depth of the object. The cells 81 .. 86 are preferably in parallel with the cells 811 .. 861 and actuate relays to give currents of differing strengths, the strength of current in the line 12 thus corresponding to the depth of the object. These " depth signals" and the picture impulses are separately transmitted and at the receiver, the picture impulses are led from terminals 42, Fig. 4, to a commutator 20 controlling lamps 16, mounted on a rotating disc, and having a central electrode and e.g. four annular electrodes corresponding to the degrees of depth in the image to be reproduced. The circuit from the lamps is completed by a distributer 34 operated by a solenoid 36 fed with the " depth signals." Alternatively a relay such as a cathode ray tube in which the cathode ray is deflected by the " depth signals " over a plurality of anodes may replace the distributer 34. The lamps may be contained in a single envelope. In a modification, at the receiver a screen of paper, gelatine, and the like is mounted upon a member, such as an iron body, adapted to be displaced in accordance with the depth signals, so that the screen is displaced according to the depth of the image. Alternatively, the screen may consist of a transparent enclosure filled with light-diffusing particles held in suspension, e.g. smoke, colloidal sulphur in water or dilute hydrochloric acid, fluorescence or chlorophyl, as in Specification 294,671, [Class 97 (i), Optical systems &c.]. A hollow lens filled with carbon bisulphide or nitrobenzene may focus the scanning beam on this screen and by placing the lens in an electrostatic field varying in accordance with the " depth signals " its focal length will vary giving various image planes in the screen. In order to provide a light of sufficient intensity to penetrate the screen, the light source is operated at a current density greater than that corresponding to its normal temperature rating. A plurality of such lamps is mounted on a rotating table so that when one lamp gets hot, another can be substituted for it. The lamps may be contained in a single container which may move with them. Specifications 266,564, 269,658, [both in Class 40 (iii), Telegraphs, Electric], and 292,365, [Class 97 (i), Optical systems &c.], are referred to.

The fibres of the webs and decorated woven fabrics may be wool, cellulosic or synthetic fibres and the carrier material may be woven or knitted scrim made from cotton, rayon or a synthetic fibre, an extruded plastics net or a bonded non- woven fabric. The laminated fabric may have an electrical heating element in the spaces between the stitch-bonding to form an electric blanket. The stitch-bonding may run in parallel rows along the length of the blanket and the spacing between the rows in the centre of the blanket may be greater than at the edges. The stitch-bonding may be prevented from running back at the end of each row by overstitching or by using a thermoplastic stitching thread which can be heat sealed to itself and the adjacent fabric. Either side of each needle-punched lamina may be placed adjacent to either side of the other and the needle-punching may be from one or both sides and may be such as to force the bulk of the web through the carrier material.

Title: Improvements in or relating to circuits for transforming the frequency of high-frequency oscillations
IPC: H03D7/22
Filed: 1952-02-29
Abstract: 714,528. Electron beam valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 29, 1952 [March 5, 1951], No. 5376/52. Class 39(1) [Also in Group XL(c)] An electron beam valve for use in a high-frequency frequency-changing circuit (see Group XL(c)) comprises a flat cathode 4, Fig. 3, emitting on two sides, control and screen grids 5, 6 respectively, and two pairs of "bunching" rods 16, 161 and 16<SP>11</SP>, 16<SP>111</SP> respectively. The two electron beams fall upon symmetrically arranged pairs of anodes 8, 8<SP>1</SP> and 8<SP>11</SP>, 8<SP>111</SP> respectively, which are cross-connected to beamdeflecting electrodes 7-7<SP>111</SP>. An anode-voltage / current characteristic is thereby obtained exhibiting negative resistance, whereby oscillations may be generated by connexion of a tuned circuit across the anode pairs 8, 8<SP>11</SP> and 8<SP>1</SP>, 8<SP>111</SP> respectively. Rod-shaped electrodes 17, 17<SP>1</SP> act to reduce the effect of secondary emission on the anodes. In an alternative construction, Fig. 4, the anodes are omitted, the deflecting electrodes 7-7<SP>111</SP> acting as current collectors. The desired negative resistance effect is obtained by means of concave reflecting electrodes 22, 22<SP>1</SP> having a voltage which is the same as, or is negative relative to that of the cathode. The arrangement is such that increase in the potential of one pair of cross-connected deflecting electrodes, e.g. 7, 7<SP>11</SP> causes an increase in the current collected by the opposing pair 7<SP>1</SP>, 7<SP>111</SP>.

Title: Improvements in or relating to television facsimile telegraph and like synchronisingsystems
IPC: H04N5/12
Filed: 1939-02-17
Abstract: 525,342. Measuring phase difference. GUANELLA, G. Feb. 17, 1939, No. 5413. Convention date, Feb. 17, 1938. [Class 37] [Also in Groups XL and XXXV] In order to maintain accurate synchronism between, the synchronizing impulses and the saw-tooth or other deflecting energy controlled thereby, the impulses and deflecting currents modulate each other, the resultant impulses being smoothed and used to control the saw-tooth or other generator. If the sawtooth voltages Vo, Fig. 1b, are in phase with the synchronizing impulses T1, Fig. 1a, the D.C. component eo of the modulation product is zero as shown in full lines in Fig. 1c, but if the saw-tooth voltage is displaced in phase as shown in dash lines in Fig. 1b, the D.C. component e1 of the modulation product varies in magnitude with the extent of departure and in sign with the sense of departure, and is used to restore the desired phase relation. The modulation may be effected by applying the signals to separate grids of a valve, Fig. 5 (not shown) or by applying saw-tooth potentials at v, Fig. 6, and synchronizing impulses at u, thus obtaining sum and difference potentials which are rectified at G3, G4, the output e being smoothed by C3, W3, W4 and applied to the relaxation generator K. Alternatively, the inductance D, rectifiers G5, G6, and resistances may be arranged as in Fig. 7, the saw-tooth signal v being interrupted periodically by the rectifiers in the rhythm of the synchronizing impulses u. The Specification as open to inspection under Sect. 91 describes relaxation oscillators the phase or frequency of which is controlled by the smoothed modulation product. The control currents may vary the charging current through valve V7, Fig. 8 (Cancelled, not shown) or the level at which the gaseous triode V8 discharges. In Fig. 9 (Cancelled) alternating potentials are applied at 26 to a pair of phase rotating networks C11 W12 and L21, W22 associated with amplifiers V1, V2 whose gain is oppositely varied by the control currents applied at 25 to produce at 22 an a.c. output of controlled phase, which may serve to control the deflecting potential of a sweep oscillator directly or after frequency multiplication. This subject-matter does not appear in the Specification as accepted.

Filed: 1924-03-04
Abstract: 235,269. Waite, F., and Waite & Saville, Ltd. March 4, 1924. Gripper mechanism.-The impression cylinder of a printing-machine is fitted with grippers 2 geared to an oscillating sector 8 for opening and closing the grippers, and the sector 8 is operated by a bowl 8<a> running in a fixed cam groove 7<a> so arranged that the grippers are positively moved by the cam to the open position and also to a position near the gripping position, the final movement to effect the gripping of the sheet being effected under spring action. The sector 8 is pivoted to a spring-pressed rod 23, guided by a bracket 25, and the rod 23 tends constantly to keep the grippers closed. The shaft 2<a> of the grippers is acted on by a spring-pressed pivoted rod 24, which, when the grippers 2 are open, tends to keep them open, but reinforces the spring action of the rod 23 when the grippers are closed by the cam 7<a>. The cam surface 7<a> is designed to be as close as possible to the path in which the pivotal centre of the grippers travels. When it is desired to retain the sheet on the impression cylinder for more than one revolution, the operating-cam for the bowl 8<a> is formed with raised flanges 7, 7<b>, Fig. 8, between which is a space 7<a> in which the bowl' 8a passes when the grippers are to be opened. A pivoted member 7f is fitted with flanges c, c<1> for controlling the bowl 8<a>, and when the grippers are to remain closed for more than a revolution the member 7f is set by the cam 13 and lever connections shown in Fig. 3 to the position shown in Fig. 8 to permit the bowl 8<a> to move though an opening c<2> on to the outside of the flange 7b, and thus to cause the grippers to remain closed. The pivoted member 7f is then returned to the position shown in Fig,. 3, and on the next rotation the bowl 8<a> is guided by the flange c<1> into the inside of the flange 7b to allow the grippers to open. In the modification shown in Fig. 3, the gear sector 8 is controlled by an extension spring 21 secured to the impression cylinder.
