Title: Improvements in and relating to space heating radiators
Inventor: MORRISON DAVID RONALD
IPC: F28D1/02
Filed: 1963-11-29
Abstract: 1,064,379. Space heating radiators; heat transmitting media. THOMAS POTTERTON Ltd. Feb. 26, 1965 [Nov. 29, 1963], No. 47220/63. Headings F4S and F4U. A space heating radiator comprises a hermetically sealed panel 1 which is partially filled with a vaporizable liquid and which is adapted for releasable connection to a hot fluid containing conduit 7. The panel may contain a small quantity of liquid in which case heat from the conduit causes boiling of the liquid and heat is transmitted to the radiant surfaces of the panel by condensation on the interior of these surfaces. Alternatively the panel may be substantially filled with liquid in which case rising bubbles transfer the heat through the liquid. The liquid may be carbon tetrachloride, ammonia, di-phenyl, a refrigerant such as " Freon " (Registered Trade Mark) or de-gassed distilled water and may have an additive such as oleic acid, benzyl mercaptan or common detergent.

Title: Improvements in or relating to sliding-clasp fasteners
Inventor: POREPP HANS
IPC: B29D5/04
Filed: 1966-10-26
Abstract: 1,167,754. Moulding sliding-clasp fasteners. H. POREPP. 26 Oct., 1966 [26 Oct., 1965], No. 48128/66. Heading B5A. [Also in Division E2] A string of sliding-clasp fastener coupling links, comprises a filament of plastics material in a serpentine or flattened helical shape that has been folded about its longitudinal centre to bring its return bends on one side towards those on the other side and close thereto, the filament at each return bend having been deformed to present a coupling head 4b. When the string is made from a filament formed to the serpentine shape the legs of each link can either have their axes lying in a common median plane as shown or alternate legs can have their axes inclined at an acute angle to each other so that looked at end-on the string has the shape of a figure 8. When the string has the first shape the coupling heads which are formed by deforming the filament at each return bend have their flat coupling surfaces projecting transversely of the longitudinal centre of the string and in the latter case the coupling heads have their coupling surfaces projecting longitudinally of the longitudinal centre of the string. A cord can be positioned inside the U-shape formed by folding about the longitudinal centre to enable the string to be sewn to a stringer tape. The serpentine strings are formed by using a device having two rows of teeth, the filament passing between the gaps in the rows of teeth from a gap in one row to an adjacent gap in the other row, the coupling head then being formed on the outside of the row after which the filament is passed either back through the same gap or back through the next gap, depending upon which form of serpentine is required, to another gap in the first row, after which another coupling head is formed on the outside of the row the process being repeated until the desired string is formed. An apparatus, Fig. 16, is described for carrying out the method automatically, this comprises two drums 13, 14, each having two parallel rows of teeth, the drums being mounted on parallel shafts and driven in opposite directions and each receiving a respective filament. Positioned adjacent the two drums is a slide 15 which reciprocates in parallel relation to the drum shafts, the slide being provided with two filament guides 15a, 15b which move the filaments relative to the teeth so that the filaments are formed to the serpentine shape. Two stamping rams (not shown) are provided adjacent the slide 15 for forming the coupling heads and associated with each drum is a disc 16 which engages the filament between the rows of the teeth to weaken the filament so that it can be subsequently bent to the U-shape by a guide 17 while a cord is guided at 20 between the arms of the U-shape, the two filaments are then heated by heating means 18 and are interengaged by wedges at the point 21.

Abstract: 1,122,846. Two-part couplings. PLESSEYUK Ltd. 11 Nov., 1965 [30 Nov., 1964], No. 48502/64. Heading H2E. The contacts of a multi-contact connector are held in position in a support by having an enlarged portion 3 of each contact trapped between two sections 7 and 8 of the support, and a coating 10 is provided on each contact to prevent the possibility of electrical leakage occurring across the gap between the two sections of the support. The support may be of either electrically insulating or conducting material. If the support is insulating the coating need only extend around the enlargements 3, but otherwise it must completely surround the part of the contact embedded in the support. The enlarged diameter part 2 of each pin contact is set back from the end of the support section to increase the electrical creepage path around the end of the support. The socket contacts are each recessed at both ends within their support.

Abstract: 1,145,390. Hydrochloric acid; alkali metal sulphates. WOODALL-DUCKHAM Ltd. 3 Nov., 1967 [8 Nov., 1966]. No. 50004/67. Heading C1A. In the process of the parent Specification, wherein HCl is produced by continually feeding NaCl or KCl and H 2 SO 4  into a boiling aqueous reaction mixture in a vessel, and permitting escape of HCl gas, aqueous reaction mass is continually withdrawn from said vessel and heat-treated to complete the reaction of 1 or 2 moles of salt with 1 mole of H 2 SO 4 . In Fig. 1, HCl gas is formed by reaction of salt and H 2 SO 4  in vessel 1, as described above. In the production of a bisulphate by-product, reaction mass from 1 passes through pump 8 to the head of HCl stripping tower 9, which it descends, at its boiling-point, in countercurrent to air and/or steam from inlet 10, so that the reaction between 1 mole of salt and 1 mole of H 2 SO 4  may go to completion, and so that HCl gas is stripped from the mixture to give a substantially chloride-free bisulphate product. Two alternative forms of HCl stripping device are described. In the production of a sulphate by-product, the reaction mass passes (instead of to a stripping device such as 9), to a spray roaster, in which it is sprayed in countercurrent to ascending hot gases at such temperature that the reaction between 2 moles of salt and 1 of sulphuric acid may take place to give a substantially chloridefree sulphate, which is removed as product, whilst the exhaust gases are scrubbed with water to remove HCI as an aqueous solution which may be recycled to vessel 1.
