Title: Improvements relating to measuring apparatus
Inventor: GOOD RICHARD SAMUEL JONATHAN
IPC: G01D5/36
Filed: 1963-11-23
Abstract: 1,070,649. Measuring position photoelectrically. FERRANTI, Ltd. Nov. 20, 1964 [Nov. 23, 1963], No.46335/63. Heading G1A. The system of Specification 988, 016, for measuring the position of a cyclic wave pattern by sampling the intensity of the pattern at a plurality of points in sequence and determining the phase of the sampled signal relative to a reference signal, is modified to permit locating of the wave pattern at a desired position by varying the phase of the sampling in accordance with a command signal. The pattern 16, Fig. 1, is secured to be moved with the worktable 11 of a machine tool by a servomotor 33. When the worktable is to remain stationary, the sampling gates G1-G4 are opened in sequence by a selector 25 in synchronism with a constant frequency command signal 14. The sampled signal is smoothed and compared in phase with a fixed frequency and phase signal 15, any departure of the worktable from its desired position causing an output from comparator 32 to operate the servomotor 33. When the worktable is to move to a new position, the phase of the command signal is changed. This results in an output from comparator 32 which drives the servomotor 33 until the worktable takes up its new position. The selector comprises a scale of N counter 35, Fig.3 (not shown) where N is the number of detectors used, and four bi-stable stages M1-M4 so connected that the first output L1 from counter 35 sets M1 and resets M3 the second output L2 sets M2 and resets M4, and so on. Two entry AND gates G1'-G4' operate to open gates G1-G4 when M4 and M1 and M2, M2 and M3, M3 and M4 respectively are set. In a modification, G1'-G4' are omitted, M1-M4 operating G1-G4 directly and being reset by the next pulse from 35 instead of the next but one. The cyclic wave pattern may be optical or magnetic.

Title: Fibrous Materials
Inventor: VOLANS PETER
IPC: F16D55/226
Filed: 1966-10-17
Abstract: 1,169,167. Artificial fibres. MONSANTO CHEMICALS Ltd. 7 Sept., 1967 [17 Oct., 1966], No. 46359/66. Addition to 1,114,151. Heading B5B. [Also in Divisions D1 and D2] Fibres e.g. of length 0À1 to 2 inches and diameter 0À001 to 0À003 inch, are produced by separating e.g. cutting into pieces, a fibre assembly comprising a three-dimensional structure of a multiplicity of interconnecting thermoplastic fibre elements (the elements in such structure being aligned in the same direction, some-5 to 50%-having branched cross-sections i.e. with offshoot fibres, and the direction of the lines of separation being transverse to such direction of alignment) and disintegrating the pieces into discrete fibres. The disintegration may be effected in bulk while the pieces are suspended in an inert liquid e.g. water. A sheet material may be formed by filtering the aqueous suspension on to a fibre-collecting filter surface. The structure may have been produced by drawing extruded foamed thermoplastic material as described in the parent Specification and from a mixture of polymers or copolymers that are not completely mutually soluble and have been bulked by heating so that differential relaxation of orientation stresses in the elements cause them to buckle. The production of polyethylene and polystyrene fibrous materials is exemplified, but a wide variety of materials may be used including polyamides, polyurethanes, polyesters, polyolefins, polyacrylonitrile, acrylonitrile-vinyl ester copolymers, regenerated cellulose, cellulose derivatives, and natural and synthetic rubbers.

Filed: 1965-11-03
Abstract: 1,073,620. Magnetic stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 3, 1965 [Nov. 20,1964], No. 46489/65. Heading G4C. [Also in Division H4] In a system for deriving double frequency signals from binary signals a stable oscillator produces a clock pulse train at twice the bit rate and means is provided for suppressing that clock pulse occurring at the middle of each bit of a particular one of the binary valves. From the clock pulses (a), Fig. 2 (not shown), from the oscillator (11), Fig. 1 (not shown), a second clock pulse train (b) at the bit rate is derived by way of a toggle (12). The first and second clock trains are gated together (13) (c) and delayed by <SP>1</SP>/ 3  bit period, the resultant signals gating (15) the binary data from a store. The signals (d) from the latter gate are passed to a toggle (14) fed also by the second clock train, this toggle's output (e) being gated (16) with the first clock train to provide the double frequency signals (f). These are fed via a toggle to a magnetic store.

Filed: 1968-10-03
Abstract: 1,194,809. Control of A.C. motors. DANFOSS A/S. 3 Oct., 1968 [12 Oct., 1967], No. 47006/68. Heading H2J. When a main switch 4 is closed a large current flows through resistor 9 to the main winding 2 of a single-phase asynchronous motor which also has an auxiliary winding 3. A trigger diode 12 responds and triac 7 is rendered conductive for allowing current to pass to the winding 3. When the main winding current decreases, the diode 12 blocks the trigger circuit for the triac 7 which becomes non-conductive to open the circuit for the winding 3. A limiting resistor 11 may have a positive temperature coefficient. All the components, except the main switch, are contained within a capsule 13.

Title: An arrangement for generating an electric control signal for correcting the elevation of a gun aimed at a target
IPC: F41G5/06
Filed: 1968-10-04
Abstract: 1,253,972. Ballistic analogue computers. AGA A.B. 4 Oct., 1968 [13 Oct., 1967], No. 47127/68. Heading G4G. Apparatus for generating voltage representing correction applied to the elevation of a gun in response to at least one factor influencing ballistic properties of the projectile comprises (Fig. 1) a series CR circuit 1, 2 and switching FET 4 energizedfrom voltage U 1  representing ballistic factors; e.g. type of ammunition, muzzle velocity, atmospheric pressure and temperature, temperature of propellant; generated by an operational amplifier responsive to input direct voltages respectively proportional to the respective factors. A pulsed control voltage L 1  (Fig. 2) over resistance 6 periodically closes the FET, and immediately prior to each closure a pulsed control voltage L 2  closes a switching FET 8 to discharge capacitor 2; the control voltages being derived from a logical circuit. Application of U 1  at time t = 0 charges the capacitor 2 progressively to voltage U C  which is applied over operational amplifier 9 to operational amplifier 10 for comparison with voltage U X  proportional to target range, for equality at t = t 1 , when a pulse U 10  is generated whose duration t 1  represents the ballistic correction, which may be converted by integrator 12 into corresponding voltage U 12 . Further ballistic corrections may be introduced by adding series RC circuit 14, 15 and FET circuit 17 switched by pulsed voltage L 1  in circuit with reference voltage U 2 , derived similarly to U 1  and representing further ballistic factors; capacitor 15 being similarly predischarged by L 2  and the charged capacitor voltage being added to that of capacitor 2 at the input of 9. A modification is described (Fig. 3, not shown) wherein a correction voltage for parallax between range-finder and gun position may be generated by instantaneously charging a capacitor at time t 0  from a voltage representing distance between gun and range-finder, over a switching FET closed by control voltage L 2 , and partially discharging the capacitor over a resistance and further switching FET closed by control voltage L 1  and re-opened at time (t 0 -t 2 ) corresponding to the target range, to disconnect the discharge circuit. The residual capacitor voltage then represents the required lateral correction for the gun.

Title: Data display apparatus
IPC: G09G5/22
Filed: 1975-11-17
Abstract: 1513179 Cathode-ray tube displays BRITISH BROADCASTING CORP 16 Nov 1976 [17 Nov 1975] 47338/75 Heading H4T In a display system such as CEEFAX (RTM) decoding for display on a TV screen digital character codes indicating standard characters (Fig. 1, not shown), one or more character codes can be redefined as modified characters by including in the data a control code followed by the character code (S) and for each code a set of bytes defining successive lines in the 10 x 6 dot matrix of the modified character; until cancelled the redefined character codes are then translated by the modified characters (e.g. ¢ in Fig. 2, not shown, is replaced by 'A' as in Fig. 3, not shown). A "page" RAM 16 stores 40 character codes forming a row for each of 24 rows per page, a character ROM 38 holds the bytes defining the ten slices of the matrix of 96 standard characters, and a character RAM 44, loaded from the data highway 11 stores the bytes of the alternative display for up to 96 characters. After the occurrence of a character redefinition code, e.g. three special codes usually in a page address, detected by 48 which then inhibits recording for display, ensuring character codes each with ten associated bytes define the address at which these bytes are to be stored in character RAM 44, serving to redefine those same codes when they occur in the display data until cleared, e.g. at the page end or otherwise. After the page address, received as a dummy row before the display rows, has been recognized 12 as one selected, other dummy rows containing character redefinitions are received, followed not necessarily in order by the 24 rows for display. After the complete page has been stored in the page RAM 16, rows in turn are extracted, and as successive scan lines are traversed by scanner 46 the bytes for successive slices of the matrix for each character in the row are read from character ROM 38 or RAM 44, for display as dots on the screen. Each of the three memories holds 1024 bytes of 8 bits; since 5 bits of row address are required to define 24 rows and 6 bits to define 40 characters in a row, the 960 character codes to be stored in the page RAM 16 can be accommodated if the combined 11 bits are reduced to 10 bits by a transcoder 24; similar requirements with transcoders 26, 62 apply to the other two memories. In storing the character codes in the character RAM 44, the eighth (parity) bit is used to indicate whether redefinition has occurred, and thus whether the character RAM or ROM is to be read. In an alternative system (Fig. 7, not shown) the bytes redefining some or all the characters are stored temporarily in the page RAM 16 and subsequently transferred to the character RAM.

Abstract: 1,004,639. Hydraulic brakes; valves. AUTOMOTIVE PRODUCTS CO. Ltd. Nov. 12, 1963 [Dec. 17, 1962], No. 47577/62. Headings F2F and F2V. A liquid pressure master cylinder 10 for vehicle brake systems is provided with a valve 31 to control the flow of liquid through a pressure outlet 15, the valve comprising a body member 41 which, under the pressure of a spring 44, is adapted to make sealing engagement with a seat around the pressure outlet 15 and the concave arcuate surface, the body member of the valve is formed with an orifice 51 which is controlled by a resilient blade-like member 53 so that the member 53 is displaced by the liquid flowing out of the master cylinder through the pressure outlet. As shown in Figs. 2 and 3 the valve body 41 has an interrupted flange 42 to guide it in the master cylinder barrel 10. On brake release the blade-like member 53 is urged against the peripheral surface of the recess 46 by liquid returning into the master cylinder so that liquid can enter the master cylinder only so long as the pressure is sufficient to compress the spring 44 of the master cylinder and move the valve body 41 away from the end of the cylinder. On brake application outward flow of liquid displaces the blade-like member 53 away from the peripheral wall of the recess and allows the liquid to flow through the orifice 51. The provision of an orifice in the peripheral wall of the recesses of the valve body 41 causes the liquid to tend to flow in a circular path around the valve body to effect scavenging of air from the master cylinder. A small hole 54 in the centre of the body 41 enables final equalisation of pressure to take place.
