Title: Improvements in or relating to group-control mechanism for record-controlled statistical machines
Filed: 1939-05-10
Abstract: 528,973. Photo-electric statistical machines. BRITISH TABULATING MACHINE CO., Ltd. May 10, 1939, No. 14010. Convention date, May 11, 1938. [Class 40 (iii)] A photo-electric statistical machine is provided with automatic group-control mechanism similar to such mechanism used in machines in which the records are read by contact pins or brushes. The machine comprises photo-electric record reading means, means for storing the photo-electric response for one cycle, and an electromagnetic relay controlled jointly by the photo-electric response from one record and the stored response of the preceding record, together with other usual devices such as adding and printing devices. The photo-electric reading mechanism is laid out as shown in Fig. 3. A photographic record film 199 is fed from a feed reel 215 to a take up reel 216 past a set of scanning apertures 226a between a lamp 210 and a set of quartz rods 228 leading to a set of cells 211. To the right of this is disposed an accumulator, Fig, 4, comprising index wheels 250, a driving motor 217, and other parts as well known in Hollerith Tabulating machines. To the right again of the accumulator is disposed a printing mechanism, Fig. 5, comprising a set of type bars 278 and hammers 285 operating opposite a platen 283 and controlled by a cam mechanism 270 and magnets 214 and associated devices. The storage mechanism comprises a plurality of cyclediscs 317, Fig. 8, formed with notches corresponding to two cycles and co-operating with pawls 321, 322, 323 on rotating arms 318, 319, 320, the pawls being controlled by two sets of catches 324, 328 operated by rotating cams 329, 326, 331 and electromagnets 325, and the arms in their controlled cyclic rotation operating contacts E1, D1 through a lever 327, all as described in Specification 215,842, [Class 106 (i)].

Abstract: 1389490 Analogue-to-digital conversion SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 24 March 1972 [26 March 1971] 14079/72 Heading G4H [Also in Division G3] In an analogue-to-digital converter wherein the output 4 of an up/down counter 9 is controlled by an input analogue quantity 1 by producing a first electrical signal at 6 indicative of the sign of the difference between the input and output, and a second electrical signal at 10 which indicates the magnitude of the difference and is the pulsed output from a voltagefrequency converter 12, the latter includes a high gain amplifier 14, Fig. 2, having a first capacitor 18 between its negative input and earth, a second capacitor 28 in a negative feedback loop, and a third capacitor 26 in parallel with a potentiometer 23 in a positive feedback loop and acting as a filter. The potentiometer 23 permits adjustment of the dead band within which the converter 12 produces zero frequency output. As shown, an analogue feedback signal 2 is derived from the output via a digital-analogue converter 5. The output of the converter 12 is fed to the counter 9 which counts up or down depending on the size of the signal 6 to produce output 4. The need for an input to converter 12 which is independent of the size of the error is avoided by the use of two negative feedback loops which correspond to the two signs of the difference signal and are switched in as appropriate under the control of gates 34, 35. The gates, which may be MOS transistors, are controlled by the sign signal 6 and an inverter 36. The output of converter 12 is taken through an exclusive-OR gate 37 to ensure single polarity pulses at 10.

Title: Electrical measuring systems
IPC: G01N9/18
Filed: 1942-10-07
Abstract: 561,269. Transformers.' KENT, Ltd., G. Oct. 7, 1942, No. 14090. Convention date, Feb. 19. [Class 38 (ii)] [Also in Groups XVIII and XXXVIII] A member immersed in a fluid and taking up a position in accordance with the specific gravity or rate of flow thereof comprises coaxial cylinders of transformer iron arranged end to end and out of contact to form the core 5 of a transformer with differentially wound secondaries 3, 4, the combined output of which is balanced automatically or manually by a voltage derived from a potential divider S coupled to a pointer 6 and if desired to a recording pen when the switch 24 is closed, the reading is corrected for temperature by the addition to the hydrometer voltage of a temperature dependent voltage derived from a network B. With switch 25 in its upper position, this correction is imperfect since the correcting voltage depends solely on the temperature and the position of slider C4 which is manually adjustable but, with switch 25 in its lower position, the correcting voltage is dependent on the position of a slider C5 coupled to the pointer 6 and therefore depends on the density as well as the temperature. In addition to or instead of network B there may be provided a source of correcting voltage varying with pressure. When the pointer is operated automatically, it is controlled by a known mechanical relay in which the pointer of the galvanometer G is periodically clamped, its position is investigated by two feeler members which cause a first clutch member to take up a corresponding angular position and this member is then brought into engagement with a second clutch member coupled to the recording pen &c. and restored to its normal angular position. The hydrometer reading may be used to control the admission to the fluid being tested of quantities of a reagent such that the density remains constant. The float is housed in a chamber 9 to which the fluid from a main stream is admitted by way of a constriction 18 and from which the fluid passes by way of an outlet 21. The pressure of air above the fluid is determined by a connection 51 to a chamber 22 to which the fluid is fed and from which it escapes by inlet and outlet pipes 19, 23 shared with the hydrometer chamber. The temperature-responsive coils are mounted in the hydrometer chamber at 38. Specification 440,648, [Group XXXVIII], is referred to.

A circuit 20 for an electrostatic loud-speaker comprises a thermionic valve 10 operating as a constant current device, and having in its anodecathode circuit a tuned circuit comprising an inductance 12 and the electrostatic loud-speaker 16 one terminal of which is connected to a condenser 17 for blocking the application of H.T. thereto, a suitable polarizing potential being connected to said terminal over resistance 18. As shown, Fig. 1, two such speakers 15, 16 operative over different frequency ranges are used in the circuit 20. Further pairs of speakers covering other frequency ranges may be connected in series as shown at 20<SP>1</SP>. Fig. 2 illustrates an alternative embodiment wherein separate blocking condensers 17, 17<SP>1</SP> are used for the speakers 16, 15. If a three-element loudspeaker is used, then the loud-speaker 16 may represent one fixed plate and the diaphragm and the condenser 17 the other fixed plate and the diaphragm. In this case the inductance 12 is centre tapped and one half of the coil only is included in the anode-cathode circuit. Push-pull voltages for the two halves of the loud-speaker are thus obtained by autotransformer action. The circuit of Fig. 2 may also be modified by providing further coils tightly coupled to coils 11 and 12 and included in the anode-cathode path of a second valve, the two valves being driven in push-pull.

Title: Machine for making steel wool from wire
IPC: B21F45/00
Filed: 1948-05-25
Abstract: 645,174. Producing metal shavings. INDUSTRIAL-HOLDING-ESTABLISHMENT. May 25, 1948, No. 14155. Convention date, May 29, 1947. [Class 83 (iii)] In a machine for making steel wool from wire, the shavings are removed from an endless wire 6 which is wound repeatedly around at least five rollers, the rollers 1, 2, 3 of which serve for guiding the juxtaposed wire turns during the shaving operation and at least the rollers 4, 5 of which serve to form a wire supply, the wire to be shaved being led, in several groups each having a number of juxtaposed turns of wire, past two series of cutters 16, 17, each cutter 74, Fig. 5, having a resiliently-mounted cutting edge opposite which there is no support for the portions of wire, and each cutting edge 75 acting in conjunction with a roller 62 which presses the portions of wire against a hard metal support 66. The rollers 1, 4 are driven by a common driving gear 90. Reels 13, 14 serve respectively for winding up the shaved wire and for introducing a new wire into the machine. The cutters 16, 17 are mounted side by side in supports 18, 19 which are secured to the machine frame so that they can be swung outwardly. A tensioning roller 8 is provided for tensioning a wire turn 7 between each pair of adjacent groups of wire turns, the rollers 8 being mounted on bell-crank levers 31, Fig. 3, and each being urged against the wire turn 7 by a weight 32 which can be raised by a hand lever 37 for adjustment purposes. When a group of wire turns is strongly stretched or if the wire breaks, a nose 40 on the bell-crank lever 31 abuts a tube 41 to stop the machine. If the wire breaks, the turns of wire are prevented from suddenly unwinding by means of rollers 28, 29. The rollers 62 are each mounted in arms 59, 60 of a cutter head 54, Fig. 5, each roller being urged resiliently against the wire turns by means of a spring 57, and the wire turns above the roller are guided and held laterally in members 65 which are each bevelled at 85 opposite the cutting edge. Mounted on a pin 73 between the arms 59, 60 is a cutter holder 72 which has a dovetailed slot in which the cutter 74 is fixed, the position of the cutting edge being determined by the pressure of a spring 81 and by a screw 82 acting through a rod 83 and a pressure pin 84. The wires are lubricated by means of oil-saturated material 87.

Title: Improvements in the manufacture and production of pigment colours
IPC: C09B57/10
Filed: 1921-05-20
Abstract: Green pigment colours are obtained by the reaction of ferric or ferrous salts on a-nitroso-b -naphthol or its bisulphite compound; ferric salts may be used in theoretical quantity or in less amount, but when ferrous salts are employed, less than the theoretical amount should be used; pyroligneous iron liquor may however be used in the theoretical amount.  Preferably Turkey-red oil or other substance which causes the pigment to be produced in a finely-divided state, for instance sodium diisopropylnaphthalene sulphonate, should be present.  The reaction may be effected in the presence of the usual substrata or these may be formed simultaneously.  In examples, ferric chloride, ferrous sulphate, and pyroligneous iron liquor, are employed.  Sodium diisopropylnaphthalene sulphonate may be prepared by treating naphthalene-a-or-b  sulphonic acid in sulphuric acid solution with isopropyl alcohol.

Abstract: 1407547 Diaphragm control circuit AGFA-GEVAERT AG 23 March 1973 [25 March 1972] 14202/73 Heading G2A A still or cine camera diaphragm aperture is adjusted by a photo-electrically controlled pulse generator. As shown, a photo-resistor 8 positioned behind diaphragm 7 is connected to a differential amplifier 10 so that the output of amplifier 10 is positive or negative depending on whether the aperture is too large or too small. If the output is positive a transistor 26 conducts and feeds pulses from an astable multi-vibrator 2 to an input E 1  to successively switch on thyristors 41, 42, 43 whereby coils 38, 39, 40 are successively energized to rotate an armature 79, Fig.2 and close the aperture. If the output is negative a transistor 30 conducts and feeds pulses from the multi-vibrator 2 to an input E 2  to switch on the thyristors 41, 42, 43 in reverse order whereby the coils 38, 39, 40 are successively energized in reverse order to rotate armature 79 and open the aperture. Instead of being located behind diaphragm 7 the photoresistor 8 may either be located behind its own diaphragm coupled to diaphragm 7 or a resistor (11') Fig.4 (not shown) may be connected to amplifier 10 and coupled for adjustment with the diaphragm 7. A rheostat may be switched in to replay the photo-resistor for manual adjustment of the diaphragm.

Title: Record disc and method of producing the same
IPC: G11B7/128
Filed: 1976-04-08
Abstract: 1509495 Disc record SONY CORP 8 April 1976 14397/76 Heading G5R In a disc record having a spiral groove of constant pitch and with the depth of groove varying with recorded signal, the groove has an inverted bell shaped cross-section of substantially the shape of a Gaussian distribution curve, which varies with groove depth to maintain the groove width at the record surface substantially constant. The signal recorded can be video information. The record is formed from a disc master 28 including a glass base 30 and a layer of photoresist material 29 in which a modulated spiral groove (or modulated spiral ridge with negative photo-resist material) is formed by developing the layer after exposure by a modulated light beam from a laser light source whilst rotating the disc and moving it in the direction of arrow 32. In order to produce the required groove shape a laser source is used which has a beam with a substantially Gaussian distribution of light intensity in the direction transverse to the spiral track formed in the master. As shown in Fig. 6 increasing depth of groove results in little change in track width. In order to prevent the amount of light per unit area impinging on the disc increasing as the scanning beam moves towards the record centre, the light intensity is reduced by a compensating filter 26 in the form of a grey scale which is moved in synchronism with movement of the beam along the disc radius.
