Title: Polyester plasticizers for vinyl resins
IPC: C08G63/20
Filed: 1965-07-23
Abstract: A plasticizing polyester of molecular weight about 700-3000 is prepared by reacting together (a) a C6- 13 alkanedioic acid, phthalic acid or isophthalic acid, (b) a C6- 18 alkanoic straight-chain acid, benzoic acid or an alkylbenzoic acid in which the alkyl group has no more than 4 C atoms, in amount such that the monocarboxylic acid provides 30-70% of the total weight of carboxylic acid, (c) glycerol, trimethylolethane, trimethylolpropane, trimethylolbutane or any mixture thereof, in amount such that the triol is equivalent to 5-55% of the total carboxyl content in the reactants, and (d) a C2- 6 alkylene glycol not containing a tertiary hydroxyl group in amount at least equivalent to the remaining carboxyl groups in the reactants. Suitable monocarboxylic acids are heptanoic, caprylic, pelargonic, capric, undecylic, lauric, myristic, palmitic and stearic acids or mixtures of these, e.g. those from hydrolysis of coconut oil or tallow, and benzoic or ethylbenzoic acids. Suitable dicarboxylic acids are phthalic, isophthalic, adipic, suberic, azelaic, sebacic, dodecanoic, and brassylic acids.  The glycols may be, e.g. ethylene, propylene, trimethylene, neopentyl, 1,3- and 1,4-butylene and 2-methyl-2-ethyl-1,3-propylene glycols and mixtures of these.  In examples, a mixture of azelaic acid and phthalic anhydride (or isophthalic acid alone) with pelargonic acid and/or a lauric/myristic/palmitic/stearic acid mixture is condensed with glycerol or trimethylol propane and ethylene or propylene glycol, or a neopentyl/propylene glycol mixture. The polyester is used to plasticize PVC resins, including PVC copolymers, preferably in amounts above 5 PHR, e.g. up to 150 PHR. In examples, a PVC resin is mixed with 70 PHR of plasticizer and an aryl phosphite and a Ba-Cd laurate as stabilizers, and formed into sheets which are tested for compatibility of the polyester, or is mixed with 55 PHR of plasticizer and a clay filler and a dibasic lead phthalate, and formed into sheets which are tested for volume resistivity, ageing properties and polystyrene marring.

Hopper 11 has a helical gutter 32 to prevent jamming. An agitator 15 is connected to shelf wheel 14 and a cone spider 40 is fixed to pin wheel 12. Cones 41 on arms 42 project through holes 44, 45 to help stir up coins. Drive is from a shaft 35 and pin 36 which engages a drive pad 75. Wiper 16 removes overlaying coins when the wheels are rotated anticlockwise as shown. Knife 18 is pivotally mounted at 38 to be adjustable to different diameter shelf wheels. Part of the knife forms one side of shoot 50 as does cover 20 and coin deflector 19. The deflector has a bent forward portion to direct coins into the shoot. There is a yieldable counter 22 which can be arranged to switch off the drive motor when a predetermined number of coins have been dispensed. Also the counter helps to propel the coins into the shoot. Rollers 30 mount pin wheel 12 accurately, the rollers may be resiliently biased.

Title: Smoke markers
IPC: B63C9/20
Filed: 1973-07-05
Abstract: 1471528 Radio signalling; aerials PAINSWESSEX Ltd 25 June 1974 [5 July 1973] 31994/73 Headings H4A and H4L [Also in Division F3]  A buoyant smoke marker for marine use comprises a smoke-generating composition and a V.H.F. radio transmitter for enabling the direction of the marker to be detected from extended distances. The marker embodies any of the forms described and claimed in Specifications 929,309 and 1,277,573. The transmitter is powered by a water activated cell or by a thermal cell deriving heat energy from the burning smoke composition, and may be supplemented by a solar cell. The transmitter includes a quartz crystal oscillator and a modulator for producing an audio signal which has a rectangular waveform and which is used to switch a radio frequency amplifier on and off in accordance with the waveform. The amplifier acts as a frequency doubler. The transmitter is in the form of a thick film circuit and is encapsulated in synthetic resin. An aerial for the transmitter comprises a plastics-covered helical dipole which is permanently erect or which is extended from within a tube by a spring (Fig. 9, not shown) when the marker is removed from a fixed mounting on the vessel. Another aerial (Figs. 6-8, not shown) comprises a pair of facing, resilient steel strips having opposed transverse curvatures, the strips being bent over or spirally wound prior to use. Yet another aerial (Fig. 5, not shown) comprises a closed or open horizontal loop (50). The marker is detectable with a directionally-sensitive, heterodyne receiver which has an oscillator and is such that the beat frequency is in the audible band. The direction of the marker is sensed by turning the receiver until the lowest note is heard. If the aerial on the marker is a loop aerial producing a sharp null in its radiation pattern, the direction of the marker is determined by looking for a minimum in the signal. The 180 degrees ambiguity of this method is overcome by using sensing equipment having a dipole aerial which can be switched in to see whether the strength of the signal increases or decreases with the aerial switched in. Alternatively, the ambiguity is overcome by using a corner reflector in the sensing equipment.

Abstract: 1352918 Spraying beam H J HOEGEN DIJKHOF GmbH 8 July 1971 [8 July 1970] 32122/71 Heading AID In an apparatus for pest control spraying of land, a spraying beam is freely suspended from a vehicle 1 about an axis 3 and includes a device by which the centre of gravity 5 of the beam can be displaced laterally from the vertical plane 6 passing through axis 3 in the horizontal position of the beam. The device may incorporate trimming weights 10, 11 displaceable longitudinally along the beam by wires 16 led directly to the driver's seat or to an electrically driven pulley or drum 15, or may comprise a mechanism, e.g. a threaded spindle 22 rotated by motor 23 to move a nut 32 pivotally connected to a suspension arm which is pivotally connected to the vehicle at axis 3 and to the beam at its centre of gravity 5. Drum 15 or motor 23 may be actuated automatically by control-signal emitters 18-20 operated by angular deviation of the beam relative to the vehicle body member 12 above a permitted degree. As shown in Fig. 7 a parallelogram system of links 21, 24-26 supporting the beam and incorporating the control-signal emitter has an adjustable link 24 which when adjusted can cause the emitter to transmit before or after the permitted value of inclination so as to allow for the suspension of the vehicle. A damping device, preferably hydraulic, may be attached to arm 18 of the emitter to prevent over-actuation of the emitter due to pitching on uneven ground. Control-signal emitters for sensing the ground surface may be provided at the ends of the beams.
