Title: Servovalve control systems
IPC: G05D7/06
Filed: 1971-08-05
Abstract: 1322818 Valves VICTORY KIDDER Ltd 5 Aug 1971 [5 Aug 1970] 36793/71 Heading F2V [Also in Divisions G3 and H3] The effective orifice of a fluid servovalve is adjusted by operating the valve between the fully open and shut positions with a variable duty ratio, effected by producing a variable mark/space ratio signal by applying the combination of a repetitive "reference" signal (a sawtooth) and an input signal (D.C.) to a threshold detector. The valve may be one of two controlling exhaust and pressure ports in a braker mechanism to control tension in a printing press. The sawtooth "reference" signal is produced by the circuit shown in which a capacitor 18 is charged through current supply transistor 12, temperature compensated by transistor 10, until the voltage on it causes conduction of unijunction transistor 24. The output is amplified at 22 and combined with the input signal at 36, 38 in resistor network 32, 34, 42. The combination is applied to operational amplifiers 44, 46 which are arranged to conduct when the combination has a positive or negative value respectively. The duration of each output pulse is thus dependent upon the magnitude of the input signal, and these pulses are applied to respective valve opening solenoids 72, 88, via drive transistors 64, 70 and 80, 86. To avoid beating between the sawtooth and resonance elsewhere in the system the sawtooth frequency may be swept over a range, repeated, e.g. once per second, by connecting a second sawtooth generator (of one second period) of similar construction to the first to control the conduction of transistors 10, 12. Circuit components are listed and a suitable valve construction is illustrated (Fig. 4, not shown).

Abstract: 879,732. Coffee-pots. SOC. TERSERAM. Oct. 29, 1959 [Nov. 10, 1958; March 13, 1959; July 3, 1959], No. 36795/59. Class 129. A coffee percolator is divided by a removable basin 5 to which is attached a container 9 with a perforated bottom 15. The dry coffee poured into the basin 5 passes through its perforated bottom 6 to the container 9 where it is compressed by screwing up the long nut 17 on a screwed rod 12. These devices are then inserted in the container and sealed by a jointing ring 4 at the neck 3. On boiling up water in the bottom, the water passes up through an adjustably telescopic tube 25 and through a ball valve 21 to flow over and through the coffee. On cooling the vacuum in the bottom may be broken by removing a plug 27 by pulling up its stirrup 28 which also allows removal of the entrails of the device. Modifications of the construction are also described and shown.

Title: Rotary cutters for mineral mining machines
Inventor: ALFORD DEREK

Abstract: 1,219,159. Mineral-mining cutter means. COAL INDUSTRY (PATENTS) Ltd. 1 Aug., 1969 [6 Aug., 1968], No. 37466/68. Addition to 1,088,845. Heading E1F. Behind a cutter tool 28 of fixedly mounted cutter tools of a rotary cutter head of a mineral-mining machine a further cutter tool 26 is so resiliently mounted on the head that the penetration of this tool over at least a substantial part of its cutting path is shallow and constant and any resultant relative movement between this cutter tool 26 and the cutter tool 28 on the tool 26 encountering a change in the mineral in which it is cutting causes means associated with the tool 26 to give a signal indicative of said movement. The tools 26, 28 may be the same or the tool 28 may be wider than the tool 26, which may project in the direction of its length beyond the tool 28. The rotary head may be a disc, a drum or a trepanning type head. The two tools 26, 28 may be mounted in separate boxes or in a common box mountable as a unit on the head. The box associated with the tool 26 houses a transducer, which emits a signal indicative of the relative movement of the tool 26 with respect to it. Means are provided for varying the spacial relationship between the tool 26 and the transducer, which may be an electromagnet. A so constructed rotary cutter head permits of an indication being given of its approach to a boundary layer of the stratum in which it is cutting so that steering adjustments can be made to the machine to keep the head in the stratum.

Abstract: 1393779 Card selector and store XEROX CORP 16 Aug 1972 [17 Aug 1971] 38228/72 Heading G4M A card selector and store has cards 101 in a drum arrangement with their outer and inner edges lying on concentric circles 102, 103. Each card carries an identity coding on one edge in the form of perforations or contrasting markings and carries further data, e.g. a microfiche or punch coding (Fig. 2, not shown). In one embodiment, as the drum is rotated each card is moved radially as shown in Fig. 1, or parallel to the drum axis (not shown), until the edge coding can be read. If contrasting markings are used light from source 110 is reflected by the card and detected by photo-cell 113. For serial read-out the codings may be scanned by a single beam or for parallel read-out a plurality of beams and detectors may be used. If perforations are used two cards are moved different distances and the rear card 107 carries a reflective coating. Alternatively the source and detector are arranged in a straight line. The coding is fed in serial or parallel to a register 401 and the identity of a required card is entered into a register 402 from a keyboard. Exclusive OR gates coupled to respective stages of the registers are arranged to feed "1"s to an AND gate 121 if the respective stages agree in value. A further register 408 receives data from a keyboard and is arranged to feed "1"s to the AND gate via OR gates 407 for those stages of the identity for which agreement is not required e.g. if a block of cards is required a "1" may be stored in the n least significant stages of register 408 to select 2<SP>n</SP> cards. An output from the AND gate operates a withdrawal mechanism 12. In a further embodiment, a surface containing light guides carrying transmitted light from a source and reflected light to detectors is situated to engage the cards as they are rotated (Fig. 5, not shown).
