Title: Method of producing sectional chocolate bodies
IPC: A23G3/02
Filed: 1927-05-06
Abstract: 271,067. Loeben, W. May 12, 1926, [Convention date]. Moulding confectionery. -Relates to a process for producing sectional chocolate bodies and consists in inserting in a mould having the general shape of the assembled article to be produced, a, number of partitions which form, on removal from the mould, part of the moulded body, subsequent separation being thereby facilitated. As shown in Fig. 1, the mould a is divided by tinfoil partitions b, c which are each slotted to engage one another. The confection is produced by pouring chocolate into the mould, either before or after the insertion of the partitions, allowing it to cool partially, inverting to drain off surplus chocolate thereby leaving a chocolate shell, putting a liquid filling into the shell and covering with a chocolate layer. The complete confection is removed from the mould and separates easily at the tinfoil partitions. The mould a may be provided with grooves in the bottom and, if desired, in the sides, to position the partitions accurately. The partitions may be of paper or board covered with metal foil or other material which will not affect, or adhere to, the chocolate, suitable materials being friction glazed paper, glazed board, waxed paper, waxed board, or parchment paper or board. In the modification, shown in Fig. 6, the partitions are intended to unite with the chocolate, e.g., the partitions may be of wafer material. In this case, each partition consists of two wafers f, one adhering to each section. When a confection of substantially spherical shape is to be produced, e.g., an apple, ball, &c., some of the partitions, which are inserted in hemispherical moulds, are arched as shown in Fig. 8. The two parts of the connection formed in the two half moulds are assembled in the usual manner.

Patent GB-716951-A (GB)
Title: Wet spinning of polyvinyl alcohol fibres
IPC: D01F6/14
Filed: 1950-05-18
Abstract: Artificial fibres are obtained by extruding an aqueous solution of polyvinyl alcohol containing gelatine, glue, a soap, Turkey red oil, or a mixture of two or more of these substances, in an amount insufficient to induce gelation of the solution, into a coagulating bath comprising an aqueous solution of an inorganic salt.  The addition of gelatine as other specified substance to the spinning solution renders it more stable and less liable to gelatinize when subjected to mechanical shock or friction during filtration and transportation at relatively low temperatures, e.g. 25-39 DEG C., and the spinning operation may be effected with less interruption and with the production of fibres of greater uniformity in their properties.  In examples, polyvinyl alcohol obtained by alkali saponification of polyvinyl acetate is dissolved in water with a small proportion of gelatine, Turkey red oil or Marseilles soap.  The solution is extruded into a saturated solution of sodium sulphate at 45 DEG C.  The spinning solution may contain 17 per cent. of polyvinyl alcohol and 0.3 per cent. of gelatine, soap or Turkey red oil.

Title: Improvements in or relating to brakes
IPC: F16D65/46
Filed: 1941-10-06
Abstract: 551,726. Brakes. BENDIX AVIATION CORPORATION. Oct. 6, 1941, No. 12888. Convention date, June 5, 1940. [Class 103 (i)] Automatic adjusting means for brake shoes is adapted to be rendered ineffective when the shoe lining has been worn to a predetermined extent. A stop device may also be provided to prevent application of the shoes to the drum after the adjusting means have been rendered ineffective. The adjusting means may also be rendered ineffective by heating of the brake. A self-energising brake is shown in which the shoes 11, 12 anchor on a stop 14 and are connected by a device comprising a part 18 in which screws a part 16 engaging shoe 11 and which is socketed in a part 22 engaging shoe 12. A pawl 25 pivoted at 24 on the part 22 has a tooth 26 for engaging a ratchet wheel 19 on the part 18 and carries a thermo-sensitive bi-metallic arm 29 engaged by a pin 31 on a link 32 connected to a bell-crank 34 pivoted at 35 on the shoe 11. The bell-crank is connected also by link 36 to the anchor 14. Upon application of the brake by the hydraulic cylinder 15, the pawl is turned by the upward movement of the link 32 and if due to wear of the shoe linings the movement is sufficient the tooth 26 slips a tooth of the ratchet wheel. During the release movement the pawl is returned by a spring 28 and by engagement of the pin 31 in a slot in the pawl. Heating of the brake causes the end of the arm 29 to leave the pin 31 thus preventing adjustment since the pin 31 has lost motion in the slot in the pawl. The adjusting means are also rendered ineffective when the linings have worn down to a predetermined extent by the engagement of a cam 39 on the part 16 with a projection 40 on the arm 29 whereby the pawl is moved away from the ratchet 19. To prevent the shoes from being forced into contact with the drum when the linings have been worn down the piston rods or links of the cylinder 15 are provided with a projection for engagement with a stop fixed to the back plate 13.
