Title: An improved method of moulding caps for bottles or like containers of synthetic resin or like substance
IPC: B29D1/00
Filed: 1936-09-26
Abstract: 482,581. Moulding caps for bottles &c. N.B. MOULDINGS, Ltd., and BELL, E. C. Sept. 26, 1936, No. 26163. [Class 87 (ii)] [Also in Group XVII] Caps for bottles or like containers are moulded from synthetic resin or like substance, the bottom part being formed as a ring of one colour on the lower end of a pin 1 and detachably held thereon so that the pin and ring can be removed from the mould and placed to. form a core in a second mould 8, the upper part 11 of the cap being then moulded in another colour so as to interlock with the moulded ring. The pin 1 is provided with a screw-thread 2 and co-operates with the first mould to form an annular groove in which the ring is moulded. The part of the pin forming the ring has a multi-start thread 5 of the same pitch as the thread 2 but of shallower dimensions to retain the ring on the pin. The pin and ring are then placed in the mould 8 with the top 10 of the ring projecting into the mould cavity and the top part 11 is moulded by the die 12. A certain amount of " flash " is left on the ring in the first moulding operation to prevent the powder forming the part 11 from spreading down the ring.

Abstract: 1,105,427. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. 14 June, 1966 [6 July, 1965], No. 26472/66. Heading G4H. [Also in Division H4] In a digital transmission system a central station can call any of any number of terminal stations by means of an address pattern comprising a start signal, an address signal, and a stop signal. Each terminal has gating means to respond to a unique address pattern and so to gate data to the output. The use of the, start and stop signals and the requirement that they be recognized as part of the address pattern permits further terminals to be added to a system without modification of the existing recognition circuits since the address signal 001, for example, of an added terminal is now unable to energize the recognition circuit of an existing terminal having an address signal 01. The recognition circuits comprise a delay line tapped to give a parallel output which is passed to a gating circuit which gives an output when a particular address pattern is received. The address pattern may be serial-parallel form, a plurality' of recognition circuits being employed at each terminal.

Title: Improvements in twisted artificial textile threads, and fabrics made thereof
IPC: D02G1/00
Filed: 1936-09-30
Abstract: 482,514. Twisting regenerated cellulose threads. DREYFUS, H. Sept. 30, 1936, No. 26518. [Classes 120 (ii) and 120 (iii)] A thread of regenerated cellulose is subjected to the action of heat, and as the final twisting operation and while the thread is hot, twist is inserted to a degree insufficient to impart crÛping power to the thread. The twist may be inserted while the thread is subjected to the action of hot water or steam, preferably under such conditions that moisture is present. Twisting may be effected by drawing the thread off over the end of a rotating package through a guide fixed in line with the axis of rotation, the thread being passed through a steam chamber on its way to a bobbin on which it is collected. A ring twister may also be used. The twisting spindle, the guide and the steaming or hot water treatment device should be so arranged that at least the last part of the twist is inserted under the influence of the steam or hot water. The floating ring device described in Specification 304,806, [Class 120 (ii)], may be used to prevent the twist from running back to the package. A suitable steaming device consists of a horizontal pipe mounted over a row of spindles and provided with eyes at appropriate points on top and bottom for entrance and exit of the threads. The pipe may be provided with upwardly projecting tubes communicating with the inside of the pipe at their lower ends and containing eyes for the passage of the threads at their upper ends. A free escape of steam may be allowed at the point at which the thread enters the pipe, for example, into a shield which surrounds the thread at this point. The presence of moisture may be assured by arranging for the condensation of steam, or by wetting the thread with water before it enters the steam. The steam may be at 95-100‹ C. and under slight pressure, and the length of the path of the thread through the steam chamber 1-3 or 3-6 inches. With hot water at 80-100‹ C., e.g. at 90- 100‹ C. and a thread speed of 2-10 metres per minute, an immersion of 1-3 inches is sufficient. The water may contain wetting agents and a small proportion of acid. The degree of twist imparted may be 40-50 turns per inch when a thread is used which has crÛping properties with a twist of 55 turns per inch. The threads may be sized, lubricated, or treated with hygroscopic or deliquescent substances before twisting. Specifications '277,089, 323,790, [both in Class 120 (iii)], 370,430, 371,461, 424,683, 424,752, 424,830, 424,879 ; 438,584, 438,585, 438,586, 438,587, [all in Group IV], and 457,538 also are referred to.

Abstract: 1,033,033. Injection moulding. GLOBE INDUSTRIES Inc. June 30, 1964 [Aug. 26, 1963], No. 27053/64. Heading B5A. In a method of encapsulating the stator of an electric motor by injection moulding, all sprues are sheared before complete curing of the moulding material whereby burr removal and stresses in the material are eliminated. In one example (Fig. 4, not shown) injection is effected by means of a nozzle 47, runners 58, gates 59, 60, around grooved sections 67, 68 of mandrels 65, 66 and into spaces 50 at the ends of a stator 32 mounted in a mould 40. To shear the sprues the mandrels 65, 66 are moved outwardly to the positions seen in Fig. 7 (not shown). In a modification (Figs. 11-13, not shown) a one-piece mandrel 75 extending outwardly at each end of the stator is used. Removal of solidified material from the grooves in the mandrel is facilitated by making the groove discontinuous by means of a thin metallic bar 83 extending longitudinally (Figs. 14-16, not shown).
