Title: Improvements in or relating to electrophotographic developing units
IPC: G03G15/10
Filed: 1961-03-13
Abstract: 951,212. Developing units. RESEARCH LABORATORIES OF AUSTRALIA Ltd. March 13, 1961 [March 17, 1960], No. 9090/61. Heading G2A. A developer unit suitable for making xerographic prints comprises a nearly vertical sloping support 2, means such as clips 3 for holding the paper 5 against the support, a nozzle 10 at the top of the support and movable therealong to direct developer liquid over the support, a trough 7 at the bottom to receive the developer, and means for pumping it from the trough back again to the nozzle. The unit may be housed in a casing 1 having a hinged glass-panelled front cover 68. The lateral movement of the nozzle 10, as shown by the arrows in Fig. 2, is controlled by a lever 39 at the front of the unit. Thus the nozzle can be moved to and fro across the sheet 5, and stopped at any place where more intensive development is required. The support board 5 itself can also be given a limited oscillatory movement, to improve the evenness of the liquid flow. The liquid collecting in the trough 7 can be re-circulated through pipes 25, 30, and valve 26 back to the nozzle 10 by means of a pump 14. A branch pipe 33 leads back to the trough, and is controlled by a tap. When the tap is open, the liquid pumped from the trough through pipe 25 returns to it through pipe 33, but on closing the tap, the liquid then passes up pipe 30 to the nozzle. Thus adjustment of tap 34 controls the amount of liquid returned to the nozzle. Volatile vapours in the casing can be removed through opening 72.

Title: Process for producing cadmium
IPC: C22B17/02
Filed: 1934-03-23
Abstract: Crude dust containing 40--65 per cent of cadmium in an oxidized state is ground and treated with sulphuric acid and then calcined. The mass is then agitated and leached with water to form an impure cadmium sulphate solution.  During this step cadmium sulphide may be added to precipitate metallic impurities of the second group. Sodium chlorate is then added to oxidize the iron present and the solution is boiled and cadmium carbonate added precipitating ferric hydroxide which carries the arsenic with it.  If iron is not present in sufficient quantity to carry down the whole of the arsenic, ferrous sulphate may be added.  The purified cadmium sulphate solution is electrolyzed for deposition of cadmium, using ferrosilicon anodes and cadmium cathode starting sheets. Specifications 392,374 and 419,508 are referred to.

Title: Needle-bar controlling device for zig-zag sewing machines

Filed: 1935-03-26
Abstract: 432,859. Sewing-machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. March 26, 1935, No. 9368. Convention date, Sept. 21, 1934. [Class 112] A vibrating needle is operated by mechanism which can be adjusted to form a zig-zag-seam or a straight seam along the zero line or along a line to either side of the zero line. During the operation of the machine, the cam 29 vibrates the yoke bar 28 and the needle 16 performs one complete up-and-down movement for each swing of the yoke. To convert the otherwise idle vibratory movements of the yoke 28 into effective endwise movements of the bar 27 to impart vibratory movements to the needle-bar gate 17, a link 34 is pivoted at 34<1> and connected at 33 to a crank arm 35. The crank arm 35 is fixed to a positioning shaft extending parallel to the shaft 30 of the cam. This shaft is rotated by a hand lever on the front side of the machine. If this shaft is rotated so that the pivot 34<1> is in the line connecting the axis of the cam 29 with the pivot 26<x>, i.e. if it coincides with the pivot 261, the link 34 performs an oscillatory movement such that the pivot 33 describes a curved path p-p and no movement is imparted to the gate 17. A straight seam is then sewn down the zero line. By rotating the positioning shaft so that the pivot 33 describes the curved paths p<1>-p<1>, p<2>-p<2>, &c., zig-zag, semi-zig-zag, or straight seams spaced from the zero line are effected.

[Class 97 (i).] In a microscope having an inclined ocular tube, a reflecting system for deflecting the imaging rays into the axial direction of the tube, and a rotatable nose-piece, the axis of rotation of the nose-piece is made to coincide with the axis of the ocular tube. The ocular tube e is mounted in a fixed frusto-conical member b to which is screwed a stationary member c. The reflecting prism d is held between the tube e and member c by a ring f and a wedge g. The rotatable nose-piece i carrying the objectives l, m is mounted on a bolt h screwed into the member c, the axis of the bolt being coincident with that of the tube e. The member c is formed with an annular space k into which objectives may extend without obstructing the rotation of the plate i, thus enabling objectives of different powers to be so mounted on the plate that, when turned into operative positions, they will be at approximately the correct imaging distance from the object to be examined.

Z may be haloalkanoyl, alkenoyl, haloalkenoyl, halotriazinyl, halopyrimidyl or may be derived from tetrameric cyanogen chloride or bromide and a number of such groups are specified.  The dyes are made by condensing a phthalocyanine di-, tri- or tetra-sulphochloride or mixture of such sulphochlorides with suitable amines, including either (a) an amino azo dye to form the radical -N(A3)-R1, or (6) an amine having a diazotizable amino group or a group convertible thereto as a substituent followed by diazotization and coupling.

Abstract: 1,224,859. Refrigeration. BRODRENE GRAM A.S. 26 Feb., 1970 [27 Feb., 1969], No. 9400/70. Heading F4H. Contact freezing elements are connected to form an endless band located on the exterior of a cabinet and running around two rollers arranged so that the band has a horizontal upper run. A freezing medium is passed through each element by pipes which project from the element to the interior of the cabinet. As illustrated, the elements 2 are formed to provide moulds 3 and have an inlet pipe 5 and an outlet pipe 6. During movement of each element along the upper run, the inlet pipe 5 collects freezing medium from nozzles 14 spaced along a distribution pipe 8. Medium drains from the pipe 6 into a sump containing a refrigerant coil (not shown) from which it is returned to the pipe 8 by a pump 9. The supply of freezing medium to the nozzles 14 is continuous so that during movement of the elements some medium passes directly to the sump. Shields 11 and 15 prevent liquid from the pipes 6 or 8 entering elements moving along the lower run. The elements may progress intermittently or continuously. The pipes 5 and 6 pass through slots 12 and 13 which have labyrinth seals formed by baffles which are carried by the pipes and by the cabinet. The baffles on the pipes of adjacent elements overlap. If liquid penetrates the seal it may drain at 20 from a space formed between the cabinet wall and a partition 19. During the final part of their upper run, the elements may be fed with a warm fluid in order to free the material frozen in the moulds. In a modification, not shown, the elements may have flat surfaces so that the upper run merely forms a travelling freezing table.
