Title: Injection moulding of thermosetting resin compositions
IPC: B29C45/40
Filed: 1968-02-20
Granted: 1971-02-08
Abstract: Injection moulding successive articles in a mould from thermosetting plastic comprises (a) withdrawing a quantity of a freely-flowing liquid thermosetting resin composition from a store of the resin, in order to fill a mould cavity, (b) injecting the withdrawn resin composition under pressure into a preheated mould cavity within a closed mould, (c) holding the resin composition in the mould until it is cured, and (d) removing the moulded article from the mould. The method and apparatus enable thermosetting resin compositions to be injection moulded, for the prodn. of all kinds of articles. The method is relatively simple, and requires no pretreatment of the resin. It is particularly useful for liquid polyester and epoxy resins.

IPC: C07C273/16
Abstract: Urea, having a relatively high biuret content, is recovered from the mother liquor remaining after crystallization of urea, of a lower biuret content, from a urea solution obtained from a urea synthesis process, by (a) converting said mother liquor to a crystal mass of urea and biuret; (b) selectively dissolving the biuret crystals in said mass by mixing said mass with a urea-biuret melt, containing 15-28% by wt. biuret; (c) separating the undissolved urea crystals (of relatively high biuret content); (d) bringing the separated melt into contact with gaseous ammonia at 120-150 DEG  C. so that some of the biuret is converted to urea and the biuret content is decreased to the range 15-28% by wt.; and (e) recycling the melt to step (b). The urea crystals of higher biuret content may be subsequently recycled to the initial crystallization step by which the urea of low biuret content is isolated.  In step (b) it is preferred to employ a mass: melt weight ratio of about 1:2.5.  The process is illustrated by reference to a schematic drawing (not shown).

Abstract: 1,257,330. Circuit assemblies. CTS CORP. 24 Dec., 1968 [26 Dec., 1967], No. 61493/68. Heading H1R. [Also in Division H2] An electrical component comprising an insulating substrate 11 containing circuit elements, is held in position on a printed circuitboard 14, during soldering, for example, by means of terminations located in at least one row of apertures in the substrate, the terminations having cam portions which resiliently engage complementary holes in the board, some of the cam portions being disposed on and extending obliquely from one side, and some from the other side, of a reference plane. In one embodiment, the terminations 12 have ends 12b in linearly disposed apertures 11b, first cam portions 12a and second cam portions 12c, alternate terminations extending obliquely on either side of a central reference plane. Downward pressure causes the terminations to snap into engagement with the board, so holding the substrate firmly and resiliently. Spacers 11a are provided on the substrate. In other embodiments (Figs. 8-12, not shown), the second cam portions are omitted, but a similar clipping action is achieved by the apertures being frusto-conical rather than cylindrical for all or part of their length. The first cam portions also enable the substrate to be suspended from rails (18), the divergence of the cam portions preventing disengagement (Fig. 7, not shown). The substrate may be a ceramic material such as alumina or steatite.

[Also in Division H4] A composite display of current and previous information (e.g. radar) is afforded by exposing an electroluminescent image-retaining device intermittently to a current-information display. In the embodiment a conventional P.P.I. display 4 is presented alternately with that on an image-retaining device 8 (which is periodically swung into a face-to-face position with display 4) to a photographic camera 9. The imageretaining device (see New Scientist, Vol. 16, pages 686 to 688) comprises a metal substrate 10 carrying vitreous-enamel layers 11, 12; layer 12 is embedded with an electroluminescent phosphor (e.g. zinc cadmium sulphide) and is coated with an electrically-conductive transparent film 13. D.C. voltage is applied between substrate 10 and film 13. Light irradiation of any area of layer 12 causes a yellowish glow to build up in that area in proportion to the intensity and duration of the irradiation, and light emission is sustained, after irradiation ceases, for some 20 minutes. Film strip 15 is stepped along intermittently and the processed frames are projected on to a screen 21. Display 4 may be of the true-motion kind; and a bearing scale, a heading line and range rings may be superimposed on each frame.
