Title: Improvements in or relating to the production of dispersions of halogenobutadienes
IPC: C08J3/03
Filed: 1935-08-15
Abstract: Aqueous dispersions of polymerized halogenobutadienes are made by dispersing 2-halogeno-1 : 3-butadiene in water in presence of an emulsifying agent comprising an inorganic salt of an organic base of high molecular weight.  The dispersion is then allowed to polymerize at a temperature not exceeding 18--20 DEG  C.  It may be stabilized, e.g. by an addition of eugenol.  The preferred emulsifying agents are (1) hydrochlorides of bases having the formula <FORM:0461279/IV/1> wherein Ac is an acyl radical having more than 5 and preferably 12--18 carbon atoms and R1, R2, R3 are hydrogen or an alkyl or aryl radical; (2) quaternary ammonium salts in which the ammonium nitrogen may form part of a heterocyclic nucleus and in which an alkyl radical containing at least 5 and preferably 12--18 carbon atoms is present, e.g. cetyl trimethyl ammonium bromide and stearyl pyridinium bromide. The preparation of these classes of compounds is described in Specifications 219,304, [Class 2 (iii)], and 379,396 respectively.ALSO:Aqueous dispersions of polymerized halogenobutadienes are made by dispersing 2-halogeno-1 : 3-butadiene in water in presence of an emulsifying agent comprising an inorganic salt of an organic base of high molecular weight.

Abstract: Polyurethane prepolymers are made by reacting a polyisocyanate with a polyether-polyester obtained by esterifying a polyalkylene ether glycol containing at least 16 ether oxygen atoms with a polymerized drying oil acid under conditions which give a polyester containing free hydroxyl groups.  Specified polyalkylene ether glycols are polyethylene, polypropylene and polybutylene glycols.  Specified polyisocyanates are 2, 4- and 2, 6-tolylene diisocyanate and mixtures thereof.  The Specification describes the conversion of the prepolymers into foams (see Group V).  In the Examples (1) and (2) a polypropylene ether glycol is condensed with a polymeric drying oil fatty acid, being a mixture of the dimer and trimer, the resultant polyester being mixed with ethyl cellulose and reacted with a mixture of 2, 4- and 2, 6-tolylene diisocyanate to produce a prepolymer which can be foamed by reaction with water and methylamine whilst Example (2) also describes the curing of the prepolymer mixed with cork granules and cobalt naphthenate.ALSO:Foamed polyurethanes are produced from polyurethane prepolymers made by reacting a polyisocyanate with a polyether-polyester obtained by esterifying a polyalkylene ether glycol containing at least 16 ether oxygen atoms with a polymerised drying oil acid under conditions which give a polyetser containing free hydroxyl groups.

Abstract: 1420696 Rotary rake head drive control TEXAS INDUSTRIES Inc 16 May 1973 [18 May 1972] 23427/73 Heading A1F A rotary rake which comprises at least one driven tined rake head whose tines 7 are pivotal between a retracted non-working position and an extended working position (shown) also includes a friction clutch within its gear box 19 to reduce the torque that tends to produce or maintain rake rotation. Each tine is pivoted to a shaft 10 and pivot arms 16, 17 and is supported by a shaft 11, all of which are connected to a single element (not shown) that is driven by a rotary plate 13, by engagement of a projection 15 and slot 14. The clutch ensures that the projection moves the complete length of the slot upon a reduction or stoppage of the tractor drive by stopping the plate 13 dead. It also prevents drive being transmitted to the rake until the tongue is sufficient to move the projection the complete length of the slot to allow the tines to take up their working position. The length of the slot may be adjustable to allow different angular working positions of the tines. The clutch may include friction plates that are spring biassed or clamped by an adjustable clamp or by a centrifugal clamp which clamps the plates below a predetermined input drive speed. The centrifugal clamp comprises pivoted arc shaped arms which are biassed together at their respective free end.

Title: Manufacture of composite articles
IPC: B29C45/16
Filed: 1978-05-30
Abstract: The composite body, for example an accumulator grid plate, is produced by means of two mould parts (130, 145) having a first and second mould cavity (135, 152) which are disposed one above the other. Displaceable means (140) can be moved between a first and second position and, in the first position, are connected to the second mould cavity (152) at the points at which it overlaps or intersects with the first mould cavity (135). Further means (148) which can be moved into a first and a second position serve, in one position, to separate the two mould cavities (135, 152) from one another. After the casting and solidification of a first material into the first mould cavities (135), the movable means (140, 148) are brought into their second positions, so that cavities (128) connected to the two mould cavities (135, 152) result. Then a flowable material is introduced into the mould cavities (152) of the second mould part (145), which material, after solidification, is interlocked with specific sections (128) of the first material. By means of this solution, the composite body can be produced in a simple manner by a mass-production process. <IMAGE>

Title: Alarm circuit for particle analysing device
IPC: G01N15/12
Filed: 1964-06-10
Abstract: 1,061,776. Particle analyzing device. COULTER ELECTRONICS Ltd. June 10, 1964 [May 1, 1964], No.24148/64. Heading G1N. In a particle analyzing device of the Coulter type and as described in Specification 968, 491 arrangements are provided to respond to blockage by debris of the test aperture. The response may give a warning, inhibit the counter, timing, or recording apparatus, and clear the aperture. The aperture may be provided with a wiping member, a blow out arrangement, or a movable plunger for ejecting the debris and these are described with references to Figs. 3, 4, 9 (not shown). The debris alarm 120 Fig. 2 is driven from the main amplifier 88, and operates an acoustic device 121, and a control binary 203, the latter of which in response to a shifting output, provides a disabling output to 'inhibit' gates 176 and 208, and stopping signals to the particle counter 67 and the time counter 210. Gas filled triode 310, is normally non-conductive but counter pulses on lead 126 are heard recurrently from the horn 124. Negative going particle pulses of normal duration from the main amplifier, which drive amplifier triode 330 away from full conduction, raise the potential across capacitor 341 but tube 340 is not fired, and the charge leaks away through tube 350 when the pulse terminates. A prolonged pulse fires tube 340 and capacitor 322 alternately charges and discharges to modulate the current through a horn operating winding 316, tube 310 operating as a relaxation oscillator at 600-800CPS. The alarm may be interrupted by opening switch 342. The inclusion of a low-pass filter in a circuit between the main amplifier and the debris alarm so that only the lower frequencies arising from a blockage are passed, is proposed as an alternative. The use of an electrical discharge through the aperture from a high voltage capacitor to clear debris is described with reference to Figs. 5-7 (not shown), the arrangement of Fig. 6 including in the debris alarm circuit a network of long timeconstant followed by a threshold device, and the arrangement of Fig. 7 including circuitry wherein particle pulses exceeding a predetermined threshold value are applied to a converter circuit such as a phantastron to produce output pulses whose amplitude is a function of the time duration of the individual pulses. The output from the phantastron is applied to operate the debris alarm through a second threshold device. Direct operation of the debris alarm through a simple threshold device is described with reference to Fig. 11 (not shown).
