Title: Electrophotographic process
IPC: G03G9/08
Filed: 1965-09-21
Abstract: 1,128,464. Printing process. MINNESOTA MINING & MFG. CO. 21 Sept., 1965 [14 Oct., 1964], No. 40254/65. Heading B6C. [Also in Division G2] An electrical conductivity pattern on an uncharged first surface is developed by bringing it adjacent a second surface bearing a uniform developer powder optionally dispersed in a dielectric liquid, and applying a D.C. potential (constant or pulsating) across the surfaces thus coating the first surface in accordance with the pattern. The powder image may be transferred to a receptor sheet under an electrical potential, optionally via a conductive drum. The conductivity pattern may be formed by imagewise exposing or inactivating a photo-conductive layer, or by using a metal plate with a pattern coating of resin thereon. A positive image is obtained by making the pattern surface the cathode. The second surface may be a roller or a brush and may be coated with conductive gelatin or rubber, rayon flock, mesh or sponge. The developer powder may be a pigment (e.g. 'Ag, Zn, Cu, Fe, Al, Fe 3 O 4 , Cu 2 O, CuCl 2 , Ag 2 O, CuO, In 2 O 3 , CdO, a lead oxide, SnO 2 , BaFeO 2 ; C or aluminized glass), or a chemical (e.g. AgNO 3 , Ag(CH 3 COO) 2  or Pb(CH 3 COO) 2 ) which reacts with another chemical on the first surface or the receptor sheet (e.g. hydroquinone); the powder may also comprise a resin (e.g. polystyrene, epichlorohydrin/phenol, polyvinylchloride or polyvinyl butyral) or other low melting compound' (e.g. benzil, bezoin, paratoluenesulphonamide or diphenylphthalate).

Abstract: 1481589 Valves SAUNIER DUVAL 3 Oct 1975 [8 Oct 1974] 40613/75 Heading F2V [Also in Division F4] A valve in the gas supply line of a heater comprises a first diaphragm 11, and chambers 13, 12 above and below it connected to the outlet and inlet sides respectively of an exhaust fan. A plunger 16 carried by a rod 14 is secured to a second diaphragm 19 closing the lower part of chamber 12, and co-operates with a seat 18 and a well 37 closed at the bottom by an adjustable stop. Bores 36 through the plunger 16 which is a loose fit in the well 37 enables a small amount of gas to pass from the inlet 8 to the outlet 34 when the plunger 16 engages the seating 18. When the exhaust fan is running above a certain speed, the diaphragm 11 moves downwardly to disengage the plunger 16 from the seat 18 and allow gas to pass at such a rate that the pressure on the diaphragm 19 reaches an equilibrium value dependent on the speed of the exhaust gas fan.

[Also in Division B3] A method of making a putlog coupler comprises bending one end of a rectangular plate into an arch, forming an arcuate recess in the transverse edge of the plate and piercing two holes into which are fitted a strap and a clamping bolt respectively. To economise in the amount of metal strip used a blank 1 is shaped so that the blanking of the tongue portion 5 in one plate forms the arcuaterecess 4 in the next plate. The blank 1 is formed into a body, Fig. 2, the lips 9 of the sheared slat 8 are formed up so that a strap 13 having a slot 14 may be pivoted about and retained in the slot 7 by the flattening of the lips 9. To assist in the forming of the body a tapered groove 10 is formed in and along the centre line. The J-bolt 12 is retained in a hole 6 by riveting the end 18 and the threaded portion with a washer and nut engages with the slot 17 in the U-sectioned end of the strap 11. In a modification a slot is pierced between the hole 6 and the body edge and the lips formed to allow the fitting of an eye bolt in place of the J-bolt 12.

The fish is positioned for a beheading operation by placing it manually between a pair of guide plates 12, 13 which are carried 'by depending arms 6b, 7b of two-armed levers 6, 7 whose other arms 6a, 7a interengage as shown to provide for simultaneous automatic adjustment, against the action of springs 11, to suit the size of the fish. The guide plates provide sloping and oblique guide surfaces 14, 15 to guide the fish into a position in which it rests with its pectoral fins overhanging horizontal and parallel support portions 16, 17. As the fish move past the end portions 33a, 34a of the levers 33, 34, these levers pivot about pivots 26 carried by the guide plates opposed by springs 29, until the abdominal integuments of the fish are indented by the projection 19, at which point the end portions 33a, 34a snap back to engage the back of the fish and retain it in position. A pair of oppositely inclined rotating cutter discs 24, 25 mounted for longitudinal sliding movement are then moved rearwardly so that the fish is beheaded, the heads pivoting backwardly about the lever end portions 33a, 34a prior to falling off into a shoot (not shown). The projection 19 is formed by a rearwardly extending apex portion of a roof-shaped member carried by an overhead supporting structure on which the levers 6, 7 are pivotally mounted.

Abstract: 1324478 Galvanising ferrous articles JOHN LYSAGHT (AUSTRALIA) Ltd 13 Sept 1971 [25 Sept 1970] 42641/71 Heading C7F Apparatus for galvanising ferrous articles, e.g. steel sheets, comprises a kettle 6 containing a lead bath 5 upon which floats a flux cover 7 and a galvanising bath 11. Both the lead bath 5 and the galvanising bath 11 contain small amounts of aluminium to suppress the formation of a Fe-Zn layer on the sheet. The sheets run between guide rolls 9, 10, and a further set of rolls 12 to control the thickness of the coating. To maintain a constant aluminium content in the bath 5 a pool of molten Al-Zn 13 floats on the surface and is contained by weirs 14. The Al content of the pool 13 can thus be varied to vary the Al content in the bath 5. The preferred Al content in the bath 5 is between 0À0005% and 0À06% and in the bath 11 is 0À14%-0À30% (although it may contain up to 20% Al). In another embodiment Fig. 2 (not shown) the Al content in the lead bath (15) is maintained by having an additional lead bath (23) having a molten Al-Zn layer (24) floating on top. The lead baths (15) (23) are connected by conduits whereby some of the contents of one bath can be pumped into the other to achieve the desired Al content. A further method of controlling the Al content of the lead bath comprises adding Al or Al alloy ingots and sheets or Al-enriched Pb ingots, to the bath. In addition, alternative means for controlling the coating thickness may be used, for instance, steam or air blasts.

Heading F1A. A control valve assembly for an hydraulic motor 16 comprises a shuttle valve 2 carrying a tappet 3 for operating a switch 4 controlling an electromagnetically-actuated reversing valve 22. Hydraulic fluid is supplied to valve housing chamber 11 by a pump 15 and, in the valve position shown, passes to motor cylinder 16 via ports 28, shuttle chamber 25, constriction 30, chamber 31, passages 32, 17 and valve 22. The pressure drop across constriction 30 causes shuttle 2 together with tappet 3 to be moved to the right against a spring 6, thereby connecting valve housing chamber 11 direct to motor cylinder 16 via shuttle groove 29 and chamber 12. When motor 16 has reached the end of its stroke, the pressures on either side of constriction 30 equalize and the shuttle and tappet are returned leftwards by spring 6, tappet 3 operating switch 4 to reverse valve 22, whereupon the cycle is repeated for the return motor stroke. The loading of spring 6 is adjustable by screw 8. Leakage past tappet 3 collects in a chamber 33 and returns to a reservoir 18, together with the motor exhaust, via passages 34, 36 and 19.
