Title: Improvements in and relating to coin freed delivery apparatus
IPC: G07F11/16
Filed: 1919-01-28
Abstract: 142,185. Brooker, H. Jan. 28, 1919. Delivery of articles stored in piles. - In apparatus specially but not solely adapted for delivering tickets, and of the type in which, by the insertion of a coin, mechanism for delivery of an article is energized and also liberated, a slide 11 is operated by a coin-energized arm 3 to withdraw the lowest article of a column and deliver it on to a guideway 19 at a lower level in an initial inward movement, and is then allowed to return to push out through the delivery slot the article withdrawn by the previous operation of the machine. The slide 11 carries on cross-bars 16a, 18 fingers 16, 17 and a cross-bar 12 the ends of which rest on guides 13, above each of which is a spring guide-member 14 having its ends curved downward to close proximity with the guide 13. The guideway 19 is inclined upwardly at its rear and is formed with slats to accommodate the fingers 17 and a cam 22 mounted on the bars 18. This cam, in the rearward motion of the slide, raises a pivoted plate 23 having a slot therein coincident with the rear portion .of the slot in which the cam 22 works, so that towards the latter part of the rearward stroke, the plate is allowed to fall and press against the guideway 19, the ticket withdrawn by fingers 16 from the pile resting on a slotted plate 4. In this rearward motion, the bar 12 rides up on the guides 14 to bring the fingers 16 into ticketengaging position. In the return movement, which is effected by spring action, the bar 12 drops on to the guides 13, and the ticket just withdrawn is caused by the fingers 17 to thrust out through the slot the ticket previously withdrawn. The coin mechanism may be of the kind described in Specifications 114,476 or 141,135.

Title: Improvements in or relating to apparatus for use in glazing earthenware articles
Inventor: BIRD GEOFFREY WALLACE
IPC: H05B6/80
Filed: 1947-01-23
Abstract: <PICT:0644207/III/1> <PICT:0644207/III/2> An apparatus for glazing earthenware or like articles comprises a substantially horizontal conveyer 10, from which depend carriers 11 supporting the articles 12 and which dips from the horizontal at B over a glaze tank 13 so that the articles are passed therethrough, means for rapidly rotating the carriers on their emergence from the tank so that surplus glaze is removed from the articles and an additional means for individually loading and unloading the carriers.  The conveyer 10 comprises a driven cable 35, Fig. 3, coupled by a spring-loaded plunger 67 to a member 31 which has wheels 32, 33 co-operating with a guide 34, and has secured thereto a rod 17.  This rod supports spring-loaded gripping arms 19, and has a cam follower 26 slidably mounted thereon and connected with the arms by links 21 in such a manner that at positions A and C, Fig. 1, where this follower contacts dams 27 and 29, the arms are opened to receive or release a plate 12.  The plates are fed to the carriers by means of an endless conveyer 53, similar to conveyer 10 and driven synchronously therewith, which carries a number of adjustable sized spaced discs 57 (see also Fig. 3), which are normally spring urged into their lower position wherein the plate is below the arms 19, but which at the transfer position, are raised so that the plate is located within the open jaws of the associated carrier, by a stem 58 contacting a fixed cam 69.  At the discharge end the plates are dumped on a conveyer (not shown) similar to conveyer 53 which transfers them to a drying oven.  The rotation of the carriers is effected by means of a pair of racks 38, 39 located by a bracket 40 on either side of the carrier and arranged to contact successively a gear 37, carried by the rod 17, so that the plate is rotated first in one direction and then in the other.  To prevent glaze being thrown from the rotated plate on to the preceding ones, the latter are isolated by a paddle device 41 which is rotated step by step through bevel gearing by a shaft 47, which is rotated by a pulley 45 supporting one end of an endless cable 43, which in turn is driven by co-operation between projections thereon and the carriers returning to point A after depositing their plates at C.  The excess glaze is returned to the tank to be circulated with the remainder of the glaze through pipes 49, 50.  On their return the carriers are passed through a cleaning tank, by a second dip in the conveyer 10, which tank is formed by a partitioned off section of the glaze tank.

Abstract: 1,203,115. Projection printing; holography. SIEMENS A.G. Jan.16, 1968 [Jan.17, 1967], No.2310/68. Headings G2A and G2J. In projection printing apparatus, a pattern 6, placed at the focal plane on the object side of a collimotor 5 of a telecentric ray system, is illuminated via a condenser 4 by a mercury vapour lamp 3, and then a focal parallel beam formed by the collimator is divided by individual reducing optical systems 7 into a plurality of individual beams each forming an associated image pattern 8. These patterns are used to expose a photo-sensitive layer 2 to give an array of the pattern 6. The layer is either aphoto-resist varnish on a semi-conductor 1 or is a layer of emulsion on a photographic plate which is later developed to form a stencil for use in the manufacture of semi-conductors. If desired, a common objective 9 may be used to further reduce the pattern size. The actinic light from the lamp 3 may be filtered out so that the array can be correctly positioned on the layer 2 before exposure is made. The lamp 3 and condenser 4 may be replaced by a laser (13) Fig.2, (not shown) part of the radiation (14) being split off to form a reference beam so that a hologram of the image patterns 8 is formed on a photographic plate (15). For the production of a stencil the developed plate is exposed to laser radiation (16) Fig.3, (not shown) giving rise to real image patterns (17) similar to the patterns 8. These patterns (17) are imaged on to a photo-resist varnish layer on a semi-conductor.
