Title: Improvements in or relating to apparatus for controlling the movement of an angularly movable type-carrying member
Inventor: EXCELL ARTHUR WILLIAM
IPC: G06K15/04
Filed: 1953-05-29
Abstract: 749,379. Typewriters &c. POWERSSAMAS ACCOUNTING MACHINES, Ltd. May 7, 1954 [May 29, 1953], No. 15068/53. Class 100 (4). Apparatus for controlling an angularly movable type-carrying member, e.g. of a statistical machine, locks and positions the member in the printing position. The typecarrying member is in two parts 1, 2, the latter supporting a gear sector 4 for co-operation with a toothed element of an accumulator, freely pivoted at 7 and urged forward by a spring 23 until a heel 15 engages a settable stop 16. The sectors are normally held in the starting position by a positive restoring element 24. Relative movement between the parts 1, 2 is permitted every time a latch 9 is disengaged from steps 12-14 on the sector 1 by its tail 20 contacting one of the control stops 17-19. Teeth 25, one for each stop 16, are provided on the sector 4 for engagement with a normally inactive pawl 26 pivoted adjacent the path of the sector 4 on a spindle 27 of a rockable support 28, 29. When the restoring element 24 releases the type-carrying member 1, 2, it moves forward under the action of the spring 23 until a stop 16 is engaged, and in timed relation with the rocking of the element 24, a rocker shaft 35 rocks an actuating arm 37 to move a cam 36 which through a follower 42, arm 40 and link 43 rocks the rockable support 28, 29 away from a stop pin 33 on the pawl 26, allowing a leaf spring 34 to force it into engagement with the corresponding tooth 25. This locks the typecarrying member in the printing position, even if the toothed element of an accumulator disengages from teeth 5 of the sector 4, until the whole apparatus is restored by the element 24. The arrangement of the pawl 26 is such that its pivot 27 is offset from the line joining the pivot 30 of the support 28, 29 to the pawl 26 but there is sufficient movement as the teeth 25 are engaged to bring the pivot 27 on to this line and to positively align the types 3 of the sectors- 1, 2 into the exact printing position. Specification 405,666, [Group XIX], is referred to.

Title: Development of electrostatic images
Inventor: METCALFE KENNETH ARCHIBALD
IPC: G03G9/12
Filed: 1963-04-17
Abstract: 1,035,953. Electrophotographic processes. COMMONWEALTH OF AUSTRALIA; DEPARTMENT OF SUPPLY. April 17, 1963,No. 15183/63. Heading G2H. A method of developing electrostatic images which comprises producing an electrostatic latent image on a base containing a photoconductor, developing the image with a suspension in a carrier, liquid of a photo-chemical substance capable of being catalysed by or reacting with a substance in the base and subsequently rendering the image visible and fixed by subjecting the deposited developer to electromagnetic waves. The photo-chemical substance may be chloro-auric acid, silver nitrate, copper sulphate,ferric chloride, lead oxide or bromo-platinec acid. In one example, a sheet of paper, wood, plastic or metal is coated with photoconductive material e.g. zinc oxide in resin according to the following composition:- Alkyd Resin 100 grms, Durham special zinc oxide, cobalt naphenate 6% 0. 5 grms, manganese napthenate 4%, tolnene 100 grms. The ingredients are milled together to produce a finely dispersed paint which is applied e.g. by roller or brush spray after the required amount of dilution with toluene. The coated sheet is cured to produce uniform electrical properties and then charged to produce a uniform surface charge and exposed to an image to produce an electrostatic image. The latent image is developed by liquid developer made as follows:- Solution A comprising chloro-auric acid 5 grms, iso-propyl alcohol 100 grms: Solution B is made by dispersing 10 grms of solution A in 100 grms of cyclohexane to form a colloidal dispersion. The liquid developer is then applied by roller or immersion and the resultant solid image is exposed to light to darken the deposit. In another example, the developer is made from Solution A containing 5 grms cupric sulphate and 100 grms idioxane and then dispersing solution A to form a 10% dispersion in Shell solvent X55 (Registered Trade Mark). In another example, for use with a photo conductive layer of bismuth trioxide, the developer may be bromoplatinic acid, 3 grms and ethyl alcohol 100 grms as a 5% dispersion in Freon 113 (Registered Trade Mark) or perchlorethylene. Another developer may be a solution of silver nitrate, 5 grms and dioxane 100 grms dispersed to form a 5% dispersion in a solution of carbon tetrachloride in a solvent. The developer may be subjected to X-rays or heat instead of visible light.

The mandrel 15 is provided with an enlarged head 19 having a socket 21, or slot (42) (Fig. 4, not shown), loosely receiving a key 22 on a drawbar 23 which is reciprocable and rotatable through a leadscrew 31. A frusto-conical portion 26 of the mandrel head 19 is loosely seated against a frusto-conical portion 27 of a hollow boss 25 which is integral with the tubular member 24 and which is secured to the drawbar 23. The mandrel 15 is thereby pivotable out of alignment of the tool axis 28 should the tool and fastener 32 be misaligned when the mandrel 15 is rotated to engage the threaded part 33 of the fastener. The amount of movement of the mandrel 15 is limited by the tubular member 24, which enters the unthreaded part 35 of the fastener. When the abutment face 14 contacts the flange 34 of the fastener, the tool body 11, 12 is moved forwardly relative to the abutment member 13 causing the leadscrew 31 to retract the drawbar 23 so as to radially deform the fastener part 35. The tubular member 24 may be separate from the boss 25 (Fig. 4, not shown).

Title: Improvements in methods of making moulds and patterns
IPC: B29C37/00
Filed: 1940-10-15
Abstract: 541,196. Making rubber moulds. UNITED STATES RUBBER CO. Oct. 15, 1940, No. 15268. Convention date, Dec. 29, 1939. [Class 87 (ii)] [Also in Group XXXVI] Metal moulds are formed by electro-deposition on patterns of rubber or like composition formed from the original mould. The pattern on being vulcanized in the original mould shrinks to some extent; this shrinkage is made up by treatment with molten paraffin wax or other agent which swells the rubber to the original size, after which the new mould 8 is formed on the pattern by electro-deposition. The pattern shown, which is for moulding pneumatic tyres, comprises a layer 5 of rubber disposed over a core 4 attached to a plate 3. The process may be employed for the production of moulds of greater size than the original by over-swelling the vulcanized patterns and employing them to produce moulds from which other patterns are formed, and so forth.

Title: Improvements in and relating to a spraying apparatus and economizer used in the construction of said apparatus
IPC: B05B13/02
Filed: 1959-05-06
Abstract: <PICT:0854704/III/1> Automatic spraying apparatus, in which a device sprays substantially perpendicularly to a conveyor and acts on its entire width, has a number of parallel feelers distributed along a line transverse to the conveyer so that they explore longitudinal bands thereof; each feeler controls contacts in one of a number of corresponding first electric circuits, closure of the contacts by an object passing the feeler actuating an operational delay device which is adapted, after a delay corresponding to the movement of the object from the line of feelers to the line of spraying, to close in predetermined sequence a number of second circuits controlling means actuating the jet or jets of the spraying device.  As shown, a conveyer belt T is driven by means E, and carries objects O beneath feelers 1 and subsequently beneath a sprayer P.  Actuation of each feeler 1 completes a separate circuit through an electromagnet 3 which operates one section of a delay device, each section consisting of a disc 5 which is rotated by the means E and carries, in a series of holes near its periphery, a number of pins which are caused to protrude on one side or the other by the action of the armature of the electromagnet 3.  Rotation of the disc 5 causes the protruding pins to operate a lever 9 and close contacts 10 after an interval corresponding to the movement of the object O for a distance L.  A number of electrically-operated spraying devices, each corresponding to a given feeler, may be employed, but in the embodiment shown, the sprayer P is reciprocated across the conveyer and is operatively connected to the arm of a switch C, which is swept across studs C1 to C11.  Each stud is connected in a circuit including a delay device corresponding to a given feeler.  In a modification, a single disc is caused to operate more than one sprayer, after differing intervals.
