Title: Improvements in valves for controlling fluid flow
IPC: G05D9/04
Filed: 1965-10-07
Abstract: 1,082,505. Soil irrigation. WESTERN BRASS WORKS. Oct. 7, 1965 [Oct. 20, 1964], No. 45245/66. Heading B2F. [Also in Division F2] An agricultural irrigation sprinkling system uses a number of valves, one at each individual sprinkler position 26. The valve (see Division F2-F3) is operated by a reciprocating and rotating drum which is indexed through a succession of angular positions until, at one angular position, the valve opens automatically. The drum is operated by a diaphragm responsive to the water pressure which is applied at repeated intervals by a pump 22 controlled by a timing device (not shown). In this manner successive areas corresponding to the hatched portion are irrigated as a number of the valves open for a determined period.

Abstract: 1,155,902. Machining lenses. QUALITY OPTICS Inc. 23 Sept., 1966, No. 42670/66. Headings B3B and B3T. In a method of machining a contour across the edge of a circular contact lens 38, the lens is held in an aligned position in a chuck assembly 102 which is spring urged into contact with a drive shaft 95 by which the axial rotation of the lens is effected. A cutting tool 90 pivotably mounted in a holder 82 is manually movable into contact with the edge of the lens and is controlled through a linkage 80, 78, 152, 150, from a control rod 34 which co-operates with a template assembly 30 adjustably located in a frame 52 on the base 40 of the machine. Optical means is provided in the form of a light source 66, 62, and a lens system in a unit 120 together with mirrors 140, 142, whereby an enlarged image of the lens edge 126 and the cutting tool edge 128 are projected on to a screen 122 in the frame unit 124 attached to the base 40. The manual movement of the control lever 34 over the template contour effects corresponding movement of the cutting tool across the edge of the lens whereby the precise machining of edge contour is affected and which is clearly visible on the screen, to the machine operator. A lens holder, Fig. 6 (not shown) is provided in which the lens is correctly aligned and a mounting member is secured thereto by an adhesive material. The lens with its aligned mounting is removed from the holder and located in the machine, the mounting means being held in the chuck during the maching operation on the edge of the lens.

Title: Improvements relating to voice operated apparatus
Inventor: GILMOUR WILLIAM DUDLEY
IPC: G10L25/00
Filed: 1966-09-24
Abstract: 1,208,262. Speech recognition. ELECTRIC & MUSICAL INDUSTRIES Ltd. 20 Dec., 1967 [24 Sept., 1966], No. 42728/66. Heading G4R. Voice-operated apparatus comprises soundrecognition means including means responsive to the sound to define intervals dependent on the period of the basic frequency of the voice, and means for counting the respective numbers of cycles of oscillation occurring in at least two frequency bands during the intervals. The speech signal at 1, after amplification. 2, 4 and attenuation 3 with slow and fast automatic gain control (A.G.C.) as shown, is fed to a low-pass filter 6 (below 700 c/s.) and a highpass filter 8 (over 700 c/s.) which feed A counters 7 and B counters 9 respectively. A counters 7 comprise two counters which count up and down respectively for an interval (viz. cycle of the basic speech frequency in the case of voiced phonemes and 10 m.secs. in the case of unvoiced phonemes, the latter being indicated if the up-counting P counter (see below), reaches 90), under control of selector 12 controlled by voicing detector 10. At the end of the interval, the counts are supplied to a decoder 26, the counter which was counting down is reset to zero and the roles of the two counters are reversed for the next interval. Thus in each interval, the counters measure the number A of oscillations from filter 6 and the change AA in this number since the last interval. B counters 9 perform the same functions for the output of filter 8. P counters 13, driven by an oscillator 14, are controlled like the A counters, and provide the basic speech pitch P and the change in this AP since the last interval. Equality of the two P counters, indicating the middle of the interval, is used to switch counters DA, DB from a count-up mode to a count-down mode. These counters, which are driven from the filters 6, 8 respectively, are reset to zero at the end of each interval and measure damping of the A and B signals. Counters T1, T2, T3 count the number of intervals in which AA = 0, AB = 0 and A = B = 0 (silence) respectively. Counters at 19, 20 measure the extent of glides i.e. changes in A and B respectively taking place between the steady states, the divide-bytwo circuits 24, 25 being responsive to the steady states of A and B as indicated to T1 and T2. G counters respond to the output of amplifier 4, rectified at 5 and converted to digital form at 17, to indicate the amplitude and change in amplitude of the speech signal. Decoder 26 responds to the counter outputs to identify successive phonemes and control a phonetic typewriter 27 (or feed a computer).

A carrying handle 5 for an electrical storage battery comprises two parallel arms 6 and 7 with inwardly bent ends 8, 9 having a length corresponding to the width of the bores in the rim of the accumulator through which the ends are passed from the top. Securing members 10 with a bent lower end portion are inserted into the bores from the bottom to fill the rest of the bores and the bent ends of the handle abut against the outer surfaces of the bent ends of the securing members when the handle is in the carrying position. In the embodiment shown the bent ends of securing member 10 abut against the lower face of the rim. Advantageously, the lower part of the bore has a widened part to accommodate the bent portion of the securing member. The member 10, which may be of synthetic resin material, may be stuck to the rim or held thereon by making at least one wall of the bore and/or widened part of an inclined or profiled form. In another embodiment which enables the handle to be pulled into a horizontal position, the widened part of the bore has a depth equal to at least twice the thickness of the bent handle ends and accommodate said end, and each bore is open towards the outer side of the rim over a part of its length extending from the top of the rim to the underside of the bent end when the handle is in the carrying position.
