Title: Foundry sands
IPC: B22C1/22
Filed: 1969-02-14
Abstract: 1,236,835. Moulding sands and binder therefor. SOC. ITALIANA RESINE S.p.A. 14 Feb., 1969 [17 Feb., 1968], No. 8289/69. Headings C3N and C3R. A moulding sand comprises a granulated base material, an organic binder (I) and a catalyst (II). I is a mixture of an oil modified alkyd resin, a polyamide and a di- or poly-isocyanate. II is selected from organic or inorganic peroxides, amines and salts of Cu, Pb, Co, Sn and Zn. II. is preferably a combination of the metal salt and a peroxide or amine. The alkyd resin may have an acid value of at least 10 and may be prepared from a polyhydric alcohol, e.g. hexane triol or pentaerythritol and a dicarboxylic acid or anhydride, e.g. phthalic acid, in a ratio of OH: COOH groups of 1À2: 1 to 4À5: 1. The oil, e.g. fish oil, soya bean, castor or linseed oil may be present at up to 50% by wt, of total monomers. The quantity of polyamide present may be 0À1-5% by wt. of the alkyd resin. The quantity of isocyanate, e.g. polymethylenepolyphenyl isocyanate, may be 10-40% by wt. of the alkyd resin. Examples of suitable catalysts are methylethylketone peroxide, sodium perborate, tertiary amines and naphthenates of Cu or Co. The binder may form 1-2% by wt. of the total composition. The compositions may be placed in moulds, removed from the moulds when self supporting and allowed to stand at ambient temperature to complete the cure. The polyamide in the composition may be present in the form of a polyamide modified, oil modified alkyd resin as described and claimed in Specification 1,236,836.

Patent GB-418365-A (GB)
Title: An improved process and apparatus for cleaning tin plates
IPC: C23G5/04
Filed: 1933-03-20
Abstract: In a process for removing grease from tin or other metal plates or sheets, the sheets are immersed in a bath of solvent then removed and flooded or sprayed with solvent, and finally are dried.  The sheets are fed at 8 into the upper run of an endless conveyer 12 which passes them downwards and immerses them in a bath of a solvent such as trichlorethylene contained in the lower part of the casing 7.  The sheets are received on cage-like carriers 13 pivotally attached to endless chains 14 which pass in a sinuous path in the upper part of the casing 7.  The plates are raised from the bath and conveyed upwards into a flooding zone formed by a partition 42 and pass between sprayers 46 fed with solvent from the bath and then between sprayers 47 fed with clean solvent.  The plates are then progressed through dripping zones 44 formed by partitions 42 to a drying zone 45 to which steam or heated air is admitted from an inlet 61 connected to a chamber containing heating coils and a fan.  The clean, dry plates are finally disengaged from the carriers and discharged through a shoot 99.  A heating coil 60 may also be provided in the upper part of the dripping zone 44 to assist evaporation.  The solvent laden air is drawn off from the drying zone 45 through a pipe 56 and passes to a scrubber in which solvent is removed.  The oily solvent in the bath overflows a weir 10 into a chamber 11 from which it is drawn off into a solvent recovery plant, the residual oil being used in the scrubber for solvent vapours.  The solvent p  bath 7 may be provided with a heating or cooling coil 73 and also condensers 74 and 75 mounted in the vapour zones.  Escape of solvent vapours at the inlet 8 and outlet 9 is prevented by a partial vacuum or by coils such as 100.  The cage-like carriers for the plates consist of a frame of side members and cross bars the upper one of which is pivoted to the endless chains.  A number of upright bars are mounted on one side of the cross bars and second series, which may be opened, are attached to a lower rotatable cross shaft forming a closed cage provided with balance weights.  The rotatable cross bar is provided at its ends with cams which engage fixed members situated at the receiving and delivery positions in the apparatus, whereby <PICT:0418365/III/1> cage.  A similar operation at the outlet position releases the plates from the carrier.  According to the Provisional Specification the plates when immersed in solvent are fed between rollers one set of upright bars opens to receive a tin plate. When the cams are disengaged a balance weight on the cross shaft closes the upright bars and the tin plate is securely held in the covered with cotton or other fabric or swansdown.  Similar rollers are also provided at the delivery position to impart a polished surface to the plates.

Abstract: 577,827. Fluid-pressure servomotors. LUCAS, Ltd., J., and IFIELD, R. J. June 23, 1942, No. 8608. [Class 135] The delivery-regulating member of a liquid fuel pump is actuated by a piston n which is movable within a cylindrical chamber o by means of pressure liquid under the control of a valve y which is moved in one direction by a spring v in response to movement of the piston and in the opposite direction by means responsive to one or more different and variable pressure or temperature conditions. In the form shown in the Figure, the piston n is connected by a plunger m to the swash-plate c of a rotary cylinder pump, the end of the chamber o adjacent the pump being supplied with liquid under pressure from the source which supplies the inlet j of the pump, this liquid flowing from the interior of the pump through a passage q with a restriction r and a port q<1>. The ends of the chamber o are connected by a passage f having at one end a seat u for the valve y carried by a pivoted lever w engaged by the end of the spring v. This lever is also engaged by the stem 5 of a diaphragm 4 separating a compartment 2, which is subjected to variable boost pressure, from a compartment 3 subjected to the exhaust back pressure of a prime mover supplied with liquid fuel by the pump. The compartment 3 also contains a capsule 7 subjected to variable temperature conditions. In one modification, the valve lever w is operated by an adjustable cam actuated by the swash-plate. In another, the swash-plate is adjusted by rotary motion derived from a fluid - operated rack - and - pinion mechanism responsive to the controlling pressures.

Title: Electrically operated speedometer and odometer
IPC: G01P3/495
Filed: 1931-03-20
Abstract: 375,816. Electric synchronous movements. SOC. ANON. DES ATELIERS BRILLI• FR’RES, 28, Boulevard de Villiers, Levallois-Perret, Seine, France. March 20, 1931, No. 8635. Convention date, March 20, 1930. [Class 40 (iii).] Actuating means for a speedometer and odometer comprises a switch formed of conducting and non-conducting parts 2, 3 respectively and driven from the shaft 1, the speed of which is required, to supply through the brushes 4, 5, 6 polyphase current to the coils 7, 8, 9 of the polepieces 13, 14, 15 of a polyphase stator 10 of a synchronous motor, the rotor of which is formed by a cobalt steel ring 16 which becomes magnetized to produce a rotating magnetic field. Fig. 4 shows a modification in which the rotor is a cvlindrical bar 36 with polepieces 37, 38 and having at one end a magnet 40. Fig. 5 shows a modification of the driving switch which allows a reversal of the direction of flow of the current in the coils of the stator. A modified construction is shown in Fig. 16 which is useful when a motor-vehicle battery is used as the source of current and it is desirable to cut off the supply when the vehicle is stationary. Current is supplied successively to the three conductors 54, 55, 56, Fig. 6, through the source of direct current connected to the vehicle-rotated shaft 52 having rigid with it a part 51 on which is pivoted a lever 49 having mounted on it a brush 48 which, when the shaft 52 is rotating, is moved centrifugally to wipe the conducting parts 45, 46, 47, but which, when the vehicle and thus the shaft 52 are stationary, is pulled by the spring 53, out of contact with the parts 45, 46, 47 to rest against the shaft 52 and thus break the supply of current to the conductors 54, 55, 56. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification, Figs. 4 (Cancelled) and 5 (Cancelled), in which the rotor 28 is U-shaped and states that the driving apparatus may be a commutator of any known type, with reversed current or not, or an alternator, or the synchronous motor may be of any known type, monophase or polyphase. This subject-matter does not appear in the Specification as accepted.
