Title: Devices for feeding articles into cartons
IPC: B65B5/08
Filed: 1956-03-16
Abstract: 778,650. Packaging-machines. HEDLEY & CO., Ltd., T. March 16, 1956 [March 17, 1955], No. 8373/56. Class 94(1). A machine for continuously feeding compressible articles into cartons comprises a conveyer for moving the articles in succession from a supply to a delivery position and means for progressively applying to the moving articles a compressive force in the direction of movement. The machine shown is arranged to insert gifts 5 into cartons 21 which are subsequently filled with soap flakes. The gifts are removed in succession from a stack by pushers 11 on an endless chain 12 and moved over a table 9 between guides 10 and 16 after lateral compression by a member 15. A second endless chain 17 carries abutments 18 and is driven at a lower speed than the chain 12 so that the abutments move into position between successive pushers 11 and each gift 5 is compressed between an abutment and a pusher until it arrives at position 5b beyond the end of the table. The cartons are moved continuously between guides 24 by a conveyer 22 driven in synchronism with the chains 12, 17 so that a carton arrives at position 21b simultaneously with the arrival of a compressed gift at position 5b. Pushers 35 are mounted for vertical movement in slotted brackets 31 carried by a pair of horizontal endless chains 25 and 26 driven at the same speed as the cartons, each pusher being fitted with a roller 38 engaging a fixed cam rail 39 whereby it is raised and then allowed to drop to transfer a gift from the grip of an abutment 18 and associated pusher 11 into a carton.

Title: Improvements in or relating to printing elements
IPC: B41N3/00
Filed: 1956-03-19
Abstract: 866,070. Printing surfaces. KEMITYPE Ltd., and GROAK, J. June 19, 1957 [March 19, 1956], No. 8548/55. Class 100(2) A printing plate, block or cylinder has a negative relief printing surface, wherein the recessed portion of the surface is divided in depth into an upper step extending continuously over the whole area of that portion to a shallow depth and a lower discontinuous step constituted by closely spaced cavities in the floor of the upper step. The plate or the like may be formed by engraving or etching the upper step and subsequently engraving or etching the lower step. The plate may be of copper, the first etch being effected through a resist covering the non-printing portions of the plate and the second etch being effected through a resist screen or pattern of slots. The resists may be produced photomechanically. A second method of producing the plate consists of engraving or etching in the printing surface of the plate the portion which is to become the recessed portion to a depth equal to the combined depth of the steps, and the applying material non-uniformly to the floor of the recessed portion e.g. by spraying or electroplating. A third method of producing the plate consists of forming the cavities of the lower step 2 (Fig. 3(a) ) in a support 1 for the printing surface, filling the cavities with a material 3 (Fig. 3(b)) to the level of the non-printing portions of the plate, coating the latter portion 4 with a resist 4, etching away the material 3 from the recessed portions of the plate and finally removing the resist (Fig. 3(c) ). In the first method the first etch may be made through a coating of a hydrophilic metal (e.g. chromium, nickel or stainless steel) and the second etch through an underlying oleophilic metal (e.g. copper or a copper alloy). In the third method the support 1 may consist of an oleophilic metal and the material 3 of a hydrophilic metal. The recessed portions of such bi-metal plates are relatively shallow, the lower step being equal to not more than three times the depth of the upper step which is preferably about 0À005 mm. thick. Such plates may be used for planographic printing. For photogravure printing the depth of the upper step may be 0À0025-0À05 mm. thick, the depth of the lower step being greater than three times that of the upper. The purpose of the cavitied lower step is to "key" the ink to the recessed portions of the plate.

Title: Improvements in the production of thermoplastic materials in fibrous or cellular form
IPC: C08L1/12
Filed: 1942-06-24
Abstract: A material of low specific gravity and high water resistance comprises a cellular mass of a cellulose ester of which at least part of the esterifying radicles are radicles containing at least eight carbon atoms, e.g. cellulose acetate-stearate.  An inert filler such as wood meal, fine sawdust, kieselguhr, or finely-ground sodium chloride may be added.  The material may be used for filling life-belts, the vacant portions of aircraft structures, tubes, or other hollow bodies, or for forming slabs or blocks.  According to an example, 55 parts of cellulose acetate-stearate of about 42 per cent stearoyl content and 30 per cent acetyl content, corresponding to 5/8 stearoyl and 2 1/8 acetyl radicles per cellulose unit of six carbon atoms, are mixed with 45 parts acetone on hot malaxating rolls until the acetone content is reduced to about 12 1/2 per cent.  The material forms sheets about 1/4 inch thick which are cut into discs and fitted into a pressure cylinder and subjected to about 3000 lbs. per sq. in. at a temperature of 210 DEG  C.  On releasing the pressure, the material escapes through a 1/8 to 1/4 inch orifice as a fluffy material of a somewhat fibrous character.  By means of a larger orifice, the material may be caused to fill a mould, or hollow body.  In another example, a p  rectangular block of light cellular material is formed which may be cut to other shapes.

In an indirectly heated steam generator which utilizes the heat liberated by the exothermic reaction of a gas conversion plant a contact chamber 5, situated above a reaction chamber 4, contains a heat absorbing tube bundle 6 forming part of the primary circuit of the generator, the operating temperature of the circuit being higher than the dew point temperature of the product gas or of the corrosive gases contained therein. The upper ends of the tubes 6 are connected to an annular collector 8 embedded in the top part 13 of the contact chamber whence vertical pipes 9 lead to a steam collector ring 10. From the latter a bridge pipe 12 connects with the vertical tube bank 14 of a heat exchanger 17 which is surrounded by a steam generating space within a cylinder 15. By regulating the water level within the cylinder 15, the upper portions of the tube bank 14 not covered by water are utilized to give varying degrees of superheat to the steam generated within the cylinder. From the heat exchanger 17 a return pipe 20 connects with a condensate distributing ring 25 which leads via pipes 23 to a lower annular collector situated at the bottom of the contact chamber 5. Also connected to the condensate distributing ring 25 are short-circuit pipes 21 running down the outside of the contact chamber from the steam collector ring 10. A burner 2, disposed within a dome 3 at the base of the reaction chamber, is provided with a switch-over device enabling the generator to be started with a normal heating gas until the primary circuit has reached a temperature exceeding the dew point temperature of the product gas.
