Patent GB-487280-A (GB)
Title: Improvements in and relating to the production of laminated products
IPC: C09J7/21
Filed: 1937-05-22
Abstract: A porous flexible fibrous web such as unsized kraft paper or towelling is impregnated with an aqueous solution of a resinous partial condensation product, dried, humidified so as to contain 20-40 (preferably 8-12) per cent by weight of water based on the weight of the dry unimpregnated web and laid either between two sheets of material, e.g. plywood, different from that of the web, or on one such sheet, the assembly being bonded together by heat and pressure.  The resinous product may be derived from cresylic acid and formaldehyde as described in Specification 470,823.  The web may be dried at 120-215 DEG  F.  The aqueous solution may be made by mixing 200 parts (by weight) of vegetable protein such as dry extracted soya bean flour or peanut flour with 1000 parts of cresylic acid, adding to the mixture a 38 DEG  B<\>ae. solution of caustic soda containing 100 parts of caustic soda, then adding 10 parts of soya bean oil and 2 1/2 parts of triethanolamine, stirring, cooling to 60 DEG  F., adding 1000 parts of 40 per cent aqueous solution of formaldehyde, stirring for 5 minutes, maintaining the mass at the temperature (70-85 DEG  C.) induced by the heat of reaction for 25-35 minutes, and adding a cold, 10 DEG  B<\>ae. solution of 60 parts of caustic soda in 2400 parts of water.  More water may be added.  In another example, the protein is omitted and the proportions varied.  In a third example, after the solution has been prepared, the partial condensation product is precipitated by adding acidulated water, the supernatant liquor is decanted off, and the soft resin is washed acid-free with water and redissolved in the decanted liquor.  The triethanolamine may be a commercial mixture of tri-, di-, and mono-ethanolamine.

Title: Improvements in and relating to gear honing machine
IPC: B23F23/12
Filed: 1960-04-25
Abstract: 911,216. Gear - finishing. NATIONAL BROACH & MACHINE CO. April 25, 1960 [June 1, 1959; .June 8, 1959], No. 14390/60. Class 83 (3). A gear honing machine comprises a tool supporting and driving assembly including a relatively light tool head 54, Fig. 5, movable relatively to the remainder of the assembly to-andfrom the work spindle, the assembly being angularly adjustable about an axis perpendicular to and intersecting both of the spindle axes. The tool T is carried on a slide 44, Fig. 2, adjustable transversely on a traversable slide 12 and the work is clamped by a centre advanced by a pneumatic device 26 on a headstock 24. The stocks are carried on a platform 20 supported at its edges by slides 32 and movable about a central pivot by a pin 34 on the slide 12 engaging an angularly-adjustable block 38 on the platform 20, to produce crowned teeth. The slide 44 carries an angularly adjustable head 50, the adjustment being gauged by a scale 68 and an adjustable arm 72 engaging an indicator 70. The tool is rotated by a motor 52 driving through change gearing and a flexible coupling to allow limited radial movement of the spindle achieved by carrying the spindle and tool directly in the head 54 which is movable in ball bearings 122 and on guide pins 126. Lateral movement is indicated on a dial 158 actuated by a rod projecting from the head. A pair of wedge-ended levers 174 can be actuated to engage a block 170 to lock the head 54 to the head 50. When the head is unlocked it can be urged towards the work by weights placed on a vertical rod 208, Fig. 12, having a cam surface 210 engaging a roller 212 on a bracket 204 pivoted at 206 and carrying a leaf-spring 202 and a dog 200, the dog engaging the head 154 of a rod projecting from the head. The downward rate of movement of the rod 208 is limited by a motor 220 acting through gearing 218, 252 and a lever 216 supporting the rod. The motor is controlled by dogs on the face of the gear 252 and can be reversed to raise the rod and to cause a cam 222 to withdraw the tool. To increase the force on the tool the leaf spring 202 may be adjusted vertically. Downward movement of the rod is also retarded by the friction of a bearing 214 and a spring-pressed plunger 246. The head may be locked after a certain in-feed has been effected. Specification 911,218 is referred to.

Abstract: 698,414. Moulding ice-cream. SEIDMAN, M. June 14, 1951 [June 14, 1950]. No. 14852/50. Class 87 (ii). [Also in Group VI]. Ice cream &c. shapes are frozen around one or more heat conducting rods 5 which thereafter act as a support for the shape during further operations e.g. coating by dipping or spraying. The rods are roughened at their lower ends. A number of heat conducting rods 5 depend from a support plate 3 which is assembled on distancing corner posts 4. The rods 5 dip into ice cream mixtures filled into moulds 2 mounted in or pressed out of a sheet metal base 1. After freezing the base is placed in warm water to allow the shapes to be withdrawn from their moulds after which the shapes are replaced to re-freeze their surface. The shapes are then dipped or sprayed with coating material. The slidable non-conducting plastic stripper plate 6 is then moved slightly away from the plate 3 which is then inverted and placed in hot water to melt the ice cream around the rods 5. The stripper plate is then slid up the inverted rod to lift off the frozen shapes. The hole made by the rods may then be filled by pouring coating material in, and re-freezing. The Provisional Specification states that the shapes may be cones, hearts, diamonds, triangles, &c.
