Title: Ultrasonic presence detector
IPC: G01S7/529
Filed: 1966-01-24
Abstract: 1,122,552. Ultrasonic presence detector. GENERAL SIGNAL CORP. 24 Jan., 1966 [31 March, 1965], No. 3064/66. Heading H4D. The invention relates to detection of vehicles or other objects by ultrasonic means. Ultrasonic pulses are radiated at such a rate and over such an angle, that a passing vehicle will produce a plurality of echoes. The invention accordingly proposes that a vehicle presence indication is not given until at least two consecutive echoes are received, and the indication remains until a predetermined time has elapsed since the last received consecutive echo. Echo pulses are received at 16 and amplified in amplifiers 17, 18 and 19. After D.C. restoration the signal is detected at 21, small amplitude echoes from people &c., rejected as being below a predetermined threshold (see Specification 953,872). The echoes passing means 21 thus arrive from reflections from the road or from nearer vehicles. The later occurring road reflections are rejected by means of a gated coincidence detector 23, such that echoes proceeding from the coincidence detector are due to vehicle reflections. These passed echoes are fed to a storage means, which after two consecutive echoes produces an output which is monitored by level monitor 26 and causes an output switch 27 to produce a vehicle presence indication. The output of switch 27 also switches on gain control transistor 110 such that resistor 106 is shorted across and the amplification of stage 18 is greatly increased. This ensures that the following vehicle echoes will all be amplified sufficiently to pass means 21. A timer reset means 30 and timer 28 are connected to the coincidence detector 23, and after a predetermined period (e.g. three repetition periods) has elapsed since the last echo pulse, the timer sends a signal to the output switch 27 whereby the vehicle presence indication is recorded and the gain of stage 18 reduced. Details of a transistorized embodiment of delay circuitry 22 are given, Fig. 2 (not shown).

Abstract: 625,158. Treating refuse. PITROIS, G. Jan. 31, 1947, No. 3093. Convention date, Feb. 19, 1946. [Class 111] In charging and discharging cells for the fermentation of garbage and the like, at least one separating element is introduced into the cell, the fermented matters below it are extracted, the element is withdrawn to allow matters above it to fall to the bottom of the cell, and the empty space thus formed at the top of the cell is filled with new matter, the volume comprised between the element and the bottom of the cell being substantially equal to the volume occupied after fermentation by the quantity of new matter introduced during the filling. In the operation of the cell shown, a separator 8, which may be in the form of a grating, is introduced into the cell between guides 10 after removing a cover 11. The fermented matters lying between the separator 8 and a bottom grating 3 then fall out of the cell on removal of an airtight door 4 and a retaining grate 6. The grate 6 and door 4 are replaced, and the separator 8 removed, when matter within the cell falls to reoccupy the space thus vacated. A volume of new material which, after fermentation, would occupy a volume equal to that between the separator 8 and the bottom grating 3 is then introduced through a top opening 1, normally hermetically closed by a cap 2. Fermentation liquid is sprayed at P upon the matters being treated, and leaves at E, and air is circulated from the bottom of the cell to the top by blowing or aspiration.

Title: Improvements in apparatus for detecting and correcting irregularities of thickness of a textile sliver
Inventor: SPEAK JOHN
IPC: D01H5/40
Filed: 1962-01-29
Abstract: 972,567. Variable speed gear. PRINCE-SMITH & STELLS Ltd. Jan. 22, 1963 [Jan. 29, 1962], No. 3314/62. Heading F2D. [Also in Division D1] In a textile drafting device, the draft applied to a sliver is regulated so that the drafted sliver is of constant thickness. As shown in Fig. 1, a sliver to be drafted by rollers 10, 11, 12 passes through a pair of measuring rollers 60, 61 which, through a mechanical linkage sets up a memory wheel 70 in response to sliver thickness; the wheel is subsequently read and the belt 59 of an opposed cone, variable speed device in the drive path to the rear drafting rollers 12, is moved so as to alter the draft applied to the sliver in a corrective manner. In the variable speed device of Fig. 1, a constantly rotating shaft 32 has fixedly mounted thereon a sunwheel 33 and a spur gear 34, the spur gear 34 driving, through a pinion 35, one cone 36 of an opposed cone and belt arrangement 36, 59, 37. The output cone 37 drives, via a pinion 38, a spur gear 39 on the planet carrier 40. The output drive to the rollers 12 is taken from a compound sun-wheel 41 and gear 42 loosely mounted on the shaft 32. In the alternative form of Fig. 5 the shaft 32 has fixedly mounted thereon a sun-wheel 332 and a spur gear 331 which drives the cone 36. The pinion 381 of the cone 37 drives an internally and externally toothed annulus 120 loosely mounted on the shaft 32; planet gears 3321 and 3322 are arranged between the internally toothed portion of the annulus 120 and the sun-wheel 332, the output drive to the rear rollers 12 being taken out by the planet carrier 3323 loosely mounted on the shaft 32. By using the above arrangements instead of the one in which input and output drives are connected directly to the cones, the whole of the driving forces are not passed through the cone and belt drive and furthermore the conicity of the cones can be reduced. Specifications 656,135, 710,957, 711,501 and 767,296 are referred to.

A bib tap, of the kind having a closure member 5 associated with an operating member such as a rotatable screwed hand knob 19 by way of a spindle 2 which is axially slidably housed in the tap body, the spindle together with the closure member being withdrawable through an opening in the tap body, and having sealing means 4 between the spindle and the body, incorporates composite stroke limiting means coacting with the body for preventing withdrawal of the spindle and closure member, this stroke limiting means being constituted by interacting parts movable with the spindle and arranged for relative displacement when desired from the exterior of the tap to render the stroke limiting means inoperative without interference with the opening and closing of the tap. An axially removable pin 26 in the spindle normally retains a loose ball detent 29 in engagement with a longitudinal groove 21 in the body to limit the lift of the valve and prevent withdrawal of the spindle and closure member. An external end of this pin is covered by a cap 34 which is assembled over a few threads 33 from which it drops free to rest on the knob 19. On removal of the spindle and closure member, an extension pin 10 of these parts allows a lenticular disc valve 13 to contact a seat 12 to shut off the flow. This disc tilts under the rush of fluid to permit normal flow and may have an offcentre bearing on the pin 10. The disc may be buoyant or be replaced by a non-buoyant loose ball. Specification 761,584 is referred to.
