Title: Sprue removal in injection moulding machines
Inventor: TURNER EDWARD DAVEY
IPC: B29C45/06
Filed: 1960-07-14
Abstract: 927,800. Injection moulding machines. TURNER MACHINERY Ltd. June 27, 1961 [July 14, 1960], No. 24578/60. Class 87(2). An injection moulding machine comprises a mould assembly and injection means adapted to co-operate with a sprue carrier having at least two sprue channel sets in such a way that whilst one set is in use in the injection process the other is automatically cleared of sprue, the sprue channel sets being changed over for subsequent injections. After a moulding cycle and starting with the mould sections apart, oil under pressure is applied a cylinder (not shown) causing rotation of a circular male mould carrier 10 through 90 degrees, so carrying off the articles 60 moulded in the preceding injection cycle and installing clean male mould cores for the next injection cycle. At the same time oil is applied to another cylinder (not shown) causing rotation of a circular sprue plate 41 through 180 degrees, carrying the sprue loaded channel set to a lower position and installing the cleared channel set in the injection zone 29, 50. The mould sections are then closed axially by a toggle mechanism so that the male mould cores enter the female mould cavities 37, which then move against springs (not shown) to press against an auxiliary headstock 22. This in turn is moved against springs (not shown) to press against a headstock plate 3. The latter movement automatically brings about the ejection of the sprue 58 from the bottom channel set by means of pins 56. The injection is performed by a nozzle 29 and the mould is again opened by the toggle mechanism and springs. In a modification, Figs. 7 to 11 (not shown), a horizontally reciprocating sprue removal system is used in place of the circular one described above, but both may be used in conjunction with two injection nozzles, e.g. for materials of different colours. Specification 908,298 is referred to.

Title: Improvements in and relating to suspensions for the pointers or moving parts of measuring instruments
IPC: G01L7/00
Filed: 1930-08-16
Abstract: 357,344. Relay devices. PAULIN, J. G., 71, Kopmangatan, Eskilstuna, Sweden. Aug. 16, 1930, No. 24617. Convention date, Aug. 17, 1929. [Class 118 (ii).] In an aneroid barometer, the movement of the diaphragm is transmitted to a " tendency " pointer which, when the instrument is to be read, is returned to zero by an adjusting device. The amount of movement of the adjusting device required to return the pointer to zero is thus a measure of the atmospheric pressure. The diaphragm chambers 13 are connected to a lever 14 suspended from the casing by a flexible strip 15. A fixed spring 16 and two adjustable springs 17 act on the lever 14 which is forked at its free end 23, 23<1>, Fig. 5. Each limb 23, 23<1> is attached to a band 24, 24<1> carrying bands 11, 11<1> secured to the pointer 1 which is itself carried by crossed bands 4, 41. A change in atmospheric pressure causes a raising or lowering of the-lever 14 and a slacking or tightening of the bands 24, 24<1> with a consequent movement of the " tendency " pointer 1. The pointer is brought back to its zero position by adjusting the spring 17 through the movement of a nut 19 on a micrometer screw 20 operated by a knob 21 having a pointer 22 reading against a scale of atmospheric pressures.

Title: Improvements in or relating to the manufacture of alkyd resins
Inventor: ARBUCKLE KENNETH HAROLD
IPC: C09K23/52
Filed: 1962-06-27
Abstract: A process for the production of an oil modified alkyd resin soluble in a mixture of water and an amphipathic solvent, containing an alkali metal hydroxide, comprises heating to esterifying temperatures a reaction mixture comprising a polyoxyalkylene glycol having a molecular weight of from 200 to 6000, a polycarboxylic acid, a polyhydric alcohol other than said polyoxyalkylene glycol and a drying, semi-drying or non-drying oil, or the fatty acids thereof, to produce a substantially-completely esterified oil-modified alkyd resin containing up to 25% by weight of combined polyoxyalkylene glycol and thereafter reacting said alkyd resin with a different polycarboxylic acid to produce a final product having an acid value of from 25 to 50.  The fatty acid radicals may be polymerized before, during or after the polymerization with unsaturated monomers, e.g. styrene, vinyl toluene or derivatives of acrylic or methacrylic acid. Amphipathic solvents are defined as being those miscible both with the alkyd resin and with water, e.g. n- and iso-propanol, hexylene glycol, the mono ethyl and butyl ethers of ethylene and diethylene glycol and the acetates thereof, the phenyl and benzyl ethers of ethylene glycol, diacetone alcohol and dimethoxy tetraglycol.  The second polycarboxylic acid preferably contains two carboxyl groups and one or more additional carboxylic groups and/or ethylenic double bonds, e.g. trimellitic, maleic, fumaric, itaconic and citric acid. In the examples, alkyds are made from phthalic anhydride, polyethylene glycol, penaerythritol, linseed oil fatty acids and:-(1) trimellitic anhydride; (2) maleic anhydride and (3) linseed oil, dehydrated castor oil, styrene and xylol, the products being dissolved in the specified solvents and ground with titanium dioxide and metal driers.  Specification 845,861 is referred to.

Title: Improvements in or relating to a method of growing a rochelle salt crystal
IPC: C30B7/00
Filed: 1948-09-21
Abstract: Rochelle's salt crystals are grown by planting a seed piece of crystalline Rochelle's salt in a concentrated aqueous solution of Rochelle's salt at a temperature <PICT:0667064/III/1> <PICT:0667064/III/2> below 40 DEG C. lowering the temperature of the solution at such a rate that the average deposit of salt per square inch of average exposed crystal area is between 1.6 and 2 grams for a total temperature drop of 15 DEG C, and effecting relative motion between the seed piece and solution, the rate of relative motion being such that the crystalline deposit is clear and the solution does not break down.  In operation 24 litres of an aqueous solution containing enough Rochelle's salt to be saturated at 37.5 DEG C and made alkaline with NaOH or KOH to 0.1-0.15N are preheated to 50 DEG C and poured into a hard rubber tray 35 preheated to 40 DEG C.  The tray 35 is securely supported in a box 10.  Four Rochelle's salt seeds 18 in. x 0.312 in. x 0.212 in. are preheated to 40 DEG C. and planted in slats in the tray 35, a rubber cover 37 put on the tray and the temperature of the solution caused to drop quickly to 38 DEG C.  The box 10 is then rocked at a rate of 4-8 cycles a minute (preferably 5 cycles a minute) through an angle of 9-18 degrees (preferably 13 degrees) and an electrical heater 40 is controlled by an automatic temperature control system 42 (see Group XXXVII) so that the temperature of the solution inside tray 35 drops in accordance with curve B.  (Curve A represents a prior-art practice).  The air is circulated around the tray by a fan 44.  When the temperature has dropped to 15 DEG C. each crystal weighs about 2 kilos.

Class 40(6) [Also in Group XIX] An indicating system comprises a cold cathode tube containing an anode and at least one cathode the latter being connected in series with a cold cathode triode for triggering a discharge at the cathode. A cold cathode numeral indicator tube 10 has ten cathodes which indicate the numerals 0-9 and one anode 11. Connected to each cathode respectively is the anode of a cold cathode triode 18, 19 &c. the h.t. for which is derived from a supply connected to terminal 26. Application of a triggering potential to any one of the triodes causes it to strike thus lowering the potential at one of the cathodes of the tube 10. To prevent more than one cathode being struck at any one time, bias capacitors, e.g. 52, are connected across the cathode resistors of each triode and capacitors 56, 57 &c. are connected from each cathode of the tube 10 to a common point or alternatively capacitors 61, 62 &c. may be connected between each cathode.
