Title: Wafer feed device
Inventor: CRISPE STANLEY WILLIAM
IPC: A21C15/00
Filed: 1965-05-13
Abstract: 1,094,231. Making sandwich biscuits. T. & T. VICARS Ltd. March 10, 1966 [May 13, 1965], No. 20165/65. Heading A2A. The upper flight 20 of an endless conveyer 22, Figs. 1 and 2 ,  carrying biscuit wafers, from a station 50, beneath a contactcoating device to a sandwich-assembling station (not shown) is supported, beneath the coating device, by rollers 24 and 38 trunnioned, respectively, in forked mountings 26 and 32, carried on two similar arms 28, each pivoted at one end 30 and connected, at the other end, to the upwardly spring-urged piston rod 40 of a hydropneumatic cylinder mechanism 42, the exhaust from which is controlled by a regulator 44. The contact coating device, which may be a contact-creamer, comprises a reservoir 10, e.g. supplying cream, a transfer roller 14, a coating roller 16 and a scraper 18. During their journey to the coating device, the wafers pass between a source of radiant energy 48, e.g. a source of light, and a device 18, which is sensitive to radiant energy, e.g. a photo-electric cell, connected to an electronic counter 46, and then under a rubber-coated pressing roller 37, which is also trunnioned in the mountings 32. When a predetermined number of wafers has been counted by the counter 46, and each of these wafers has been coated with a substance such as cream or jam, and the coated wafers have been stacked, the counter 46 starts the mechanism 42, so that each piston rod 40 moves downwardly into its cylinder and thus swings the associated arm 28 and rollers 24, 38 downwardly, to lower the flight 20 into the position indicated by the chain line in Fig. 1, thus ensuring that the next wafer is carried, uncoated, to the sandwichassembly station, where it is placed on top of the stack of coated wafers to form a sandwich biscuit. The cylinders are then exhausted through the regulator 44 and their piston rods 40 move upwardly to bring the flight 20 into its normal, undistorted position, indicated by the full line in Figs. 1 and 2. Each cylinder of the mechanism 42 may be double-acting, and a spring-return link may be inserted between each cylinder and its associated arm 28. The mechanism 42 may be controlled by an adjustable electronic delay.

Title: Improvements in the production of sprayed coatings
IPC: B05B12/20
Filed: 1951-08-28
Abstract: <PICT:0780727/III/1> <PICT:0780727/III/2> Apparatus for producing sprayed coatings comprises a spraying nozzle, means for feeding a liquid composition at constant volume in unit time to the nozzle, means for supplying a gaseous fluid under pressure to the nozzle in order to deliver the liquid composition therefrom in the form of a narrow finely-atomized jet, a table adapted to support the surface to be sprayed with its plane normal to the axis of the jet, means to produce relative reciprocating motion between the table and the spraying nozzle at a relatively high speed, and further means to produce relative motion between the table and the spraying nozzle at a relatively low speed in a direction at right-angles to the relative reciprocating motion, both relative motions being such as to maintain the plane of the surface to be sprayed at a uniform distance from the spraying nozzle and being so related to each other in speed and extent that adjacent strips of composition laid down on the surface will merge together at their longitudinal edges.  In an apparatus for coating a carrier of an insulating material, e.g. glass, with a material having a high specific electrical resistance, which is bonded to the carrier by an ethoxylene resin, the carrier member, in sheet form, is mounted beneath a mask on a table 2, which is mounted for reciprocation along antifriction guide members 10 on a carriage 11, by means of a connecting-rod 14, pivoted on a disc 15 driven through gearing 16 by an electric motor 17 mounted on the carriage 11.  The carriage 11 is itself mounted for reciprocation at a lower speed along guides 18, being attached to an endless band 19 which runs over pulleys 20, one of which is driven through gearing 21 by a reversible electric motor 22, the carriage 11 having stops 24 which are adapted to engage switches 23 for reversing the motor 22 at either limit of its travel.  The table 2 is thus caused to be "scanned" by the spray 12 from a nozzle 13 which is attached to a container (Fig. 3) the lower half 25a of which is cylindrical and the upper half 25b rectangular in cross-section.  A piston 26 in the half 25a is attached, by two rods 27 running through holes in a fixed disc 30, to a nut 28, which co-operates with a threaded spindle 29, the inner end of which is rotatably mounted in the disc 30, while the outer end is driven through gearing 31 by a motor 32.  Liquid resistor composition, in the lower half 25a of the container, may thus be discharged at a controlled rate through the outlet 33 which is connected to a fine-bore tube 34, surrounded by a chamber 35 having a tapered outlet 36, and a compressed air inlet 38.  In operation, after adjustment of the nozzle 13 relative to the table 2, and of the length of traverse of the carriage 11 by means of the limit switches 23, the three motors 17, 22 and 32 are switched on simultaneously, and compressed air is supplied to the chamber 35. Specification 751,001 is referred to.
