Title: Device for pneumatic cleaning of surfaces in textile spinning and winding machines
IPC: D01G15/76
Filed: 1965-05-04
Abstract: 1,041,164. Cleaning machines. LUWA A.G. May 4, 1965 [May 5, 1964], No.18794/65. Heading D1F. [Also in Division F4] In pneumatic cleaning apparatus on a spinning machine e.g. a roving or slubbing frame, dust, fluff and fibres released by the sliver F passing through drafting rollers 28 (a) are entrained by an air flow 30 extending through a chamber 24 and conveyed to a filter 15 (on the intake side of a blower 3) through duct 26, connector 20, duct 21, pipe 22 and conduit 14 or (b) fall towards the lower part of the machine and are swept by blowing air currents 31, issuing from nozzles 8 and flowing over the stepped surfaces 7b-7d, into a trough 10 whence they are withdrawn by suction through a conduit 11, a suction chamber 13 and conduit 14. Pressure air supplied by blower 3 passes through a conduit 2 and duct 1, thence through distribution chamber 6 and connector 16 to chamber 24.. When a hinged lid 17 is raised the air circuit through chamber 24 is interrupted at the connectors 16 and 20. The distance between nozzles 8, considered in the direction of air flow, is four to ten times the equivalent diameter of the nozzle.

Title: Method and apparatus for measuring particle concentration in a fluid suspension of particles
Inventor: COULTER W H
IPC: H03K5/153
Filed: 1972-04-24
Abstract: 1385363 Particle analysis COULTER ELECTRONICS Ltd 24 April 1972 [28 April 1971 4 Jan 1972] 18899/72 Heading G1N [Also in Division H3] The invention relates to apparatus for monitoring pulses from Coulter type apparatus to determine particle concentration in a fluid suspension. Since the pulses have no well-defined ends the duration of a defined part from the middle of pulse is monitored and these durations are averaged. The part of the pulse chosen may be:-  (i) the width at half peak amplitude, (ii) the peak to half amplitude width or (iii) the first point of inflection to the last point of inflection, (i.e. about half-way up the flanks of the pulse).  In arrangement (i) Figs. 3A, 3B (not shown) the delayed pulse is compared with a half-height plateau by techniques as described in Specification 1355215 and the width signals are arranged e.g. by a well-damped meter or timed integration Fig. 4, (not shown). Arrangement (ii) Figs 5A; SB (not shown) the peak height position is found by differentiation in one channel to set a flip-flop, and the fall to half amplitude as previously in a parallel channel resets the flip-flop. In this arrangement the differentiator drives a saturable amplifier to produce a square wave (H) which is further differentiated to produce a spike (I) at the peak position. In arrangement (iii) Figs. 6A, 6B (not shown), which may handle compound pulses (such as 6-21), the points of inflection are found by double differentiation (graph D) and pin pointed by squaring and differentiating (E), (F). A time (or width) signal is provided by an integrator generating a ramp output (J) started by the first inflection pulse. Subsequent inflection pulses set the ramp amplitude into a pair of series-connected sample-and-hold circuits and step the values forward. Thus when the pulse ends, as determined by the low-threshold signal (B), the last stored value will be that at the zero point of the pulse, and the required value will be the last but one signal held in the second sample-and-hold circuit. An alternative and more complex way of doing this is disclosed with reference to Figs. 8, 9A, 9B (not shown). The double differentiated signal (F) is added to the low-threshold signal (I) to produce a stepped wave (J) from which the points of inflection (where it crosses the zero line) are more easily determined. In another channel the original pulse is clamped and delayed by an amount equal to that unavoidably introduced in the differentiating channel, whereby the pulse amplitude at the point of inflection can be stored to compare with the trailing pulse flank.

Title: Improvement in or relating to heating installation
IPC: F24D3/02
Filed: 1931-06-30
Abstract: 385,336. Heating buildings. LEMAISTRE, M. J. G. A., 19, Rue de Cheroy, Paris. June 30, 1931, No. 18927. Convention date, June 30, 1930. [Class 64 (ii).] In a hot-water system comprising a water heater, an upper expansion and heater reservoir, and an ejector aspirator for causing the circulation, a release and regulation compartment is provided between the ejector proper and the heater through which steam from the heater must pass to reach the ejector, said compartment communicating with a chamber of the ejector by orifices or tubes so dimensioned as to prevent sharp variations in the pressure of liquid or vapour in the ejector from affecting the heater, to give a uniform temperature in the ejector, and to reduce the period of ejection. Circulation is established between a heater A and ejector-aspirator B by way of tubes 4, 5. The ejector may be inside the heater. Steam formed in the bell 1 forces hot water into the reservoir D, by way of the tube 6 and bell C, from which it is aspirated by the condensation and vacuum produced in the ejector, passing into the circuit 8, 10 and radiators R, through the chamber 9, heat exchanger E, and back to the ejector by a series of tiered openings 12, 12a, 12b, 13 in the tube 11 of progressively reduced diameter. The bell 1 has one or more annular partitions 17, and connects with the part 2 by a neck 20 in which is fitted a separator 21 for the water and steam, shaped as shown in Figs. 1 and 4. The part 2 comprises a central chamber 29 whose top portion 26 overhangs the release and regulation compartment 27 communicating therewith by tubes 28, 30. The ejector terminates in a part 3 comprising a tube 32, receiving the end of the tube 11 and surrounded by a sheath 31 ending in a compartment 33 connected to the heater by one or more tubes 5. The annular space is partially closed, for example, by partitions. A tube 14 feeds return water to a regulator 15 supplying air or fuel to the heater. This water may be mixed with water from a branch pipe of the pipe 11 and returned to the valve 100. The reservoir D comprises three portions 50, 51, 52 of increasing diameters. The part 50 containing the bell C has an emptying funnel F and outflow 8. The part 51 can hold the maximum pulsation possible, and the top portion 52 serves as a steam chamber and communicates with a condensation compartment 53, separated therefrom by a plate 58 pierced at 59 to allow the passage of air and steam, either at its centre or the extremity of a diameter, and having tubes 64 for condensed water. Plates 65 may be arranged to form tortuous paths for the air and steam before they reach the orifice 59. Other means for breaking up the steam may be provided. A tube 62 serves for escape of air, most of the steam being condensed. The reservoir may comprise only the parts 50, 51 and a simple cover 57. Steam and air from the cover 57 may be condensed in a tube placed in a hot-water tank and the condensate returned to reservoir D.

Abstract: 389,701. Clutches. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. July 5, 1932, No. 18930. Convention date, July 30, 1931. [Class 80 (ii).] Free -wheel clutches for use especially in the transmission sustems of motor vehicles comprise a nut 20 screwed on a driving shaft 19 and adapted to compress friction rings 23, 24 against a spring disc 26, which is backed a by projection 14 on a cup 22 keyed on the driven shaft 21. If the load is such as to force a projection on the nut against the disc the latter yields and the clutch is disengaged. Stop plates 27, 28 are screwed on to the nut 20 and cup 22 respectively, while a hand-lever 39, a lever 31 carried by a ring 40 rotatable on the cup 22, and a forked lever 35 are provided for controlling the nut 20. When applied to a vehicle this arrangement allows of the engine being used as a brake, for if, when the vehicle is running downhill and the clutch has been disengaged, the rod 31 is moved to the left, it drives the nut 20 which thereupon turns on the shaft to bring the plate 27 to bear on the rings 23, 24 and compress them against the plate 28, thus rotating the engine. The clutch can be disengaged whilst the engine is driving by rocking the lever 35 to the right ; if the engine is being driven, by rocking it to the left. The Specification as open to inspection under Sect. 91 comprises also the modified construction shown in Fig. 1 (Cancelled), in which a nut 4 screwed on a driving shaft 19 compresses friction rings 9, 10 against a spring disc 13, which is backed by the projection 14. This subject-matter does not appear in the Specification as accepted.
