Title: Improvements in or relating to polymeric substances
Inventor: CHARLESBY ARTHUR
IPC: B29C71/04
Filed: 1952-09-24
Abstract: Polymers with a chain structure of carbon atoms having hydrogen atoms attached thereto and which change from a crystalline to a molten state on heating, e.g. polyethylene, are cross-linked by subjecting them to ionising radiation at a temperature sufficiently high for the crystalline state to be partially or wholly destroyed.  In examples, polyethylene rod in an aluminium can is heated at 100 DEG  to 150 DEG C. in a thermal nuclear reactor with a density of approximately 1012 neutrons per square centimetre per second for periods sufficient to give dosages of 3 and 8 X 1017 thermal neutrons per square centimetre.  The product, which is pliable and elastic, has increased resistance to organic solvents and cold drawing.  Specifications 732,047 and 739,709 are referred to.

Title: Improvements in and relating to change giving apparatus
IPC: G07F5/24
Filed: 1923-09-25
Abstract: 227,891. Smith, J., and Thompson, F. Sept. 25, 1923. Money-delivering apparatus.-Change for a, currency note is given by a machine of the sliding bar type fitted with a clutch mechanism to connect a normally disconnected operating member to the note receiving and change releasing means. Fig. 1 shows a front view of the machine with the case removed, and Fig. 2 shows a side view.. Figs. 4 and 5 show sectional views on the lines 4-4, 5-5, respectively in Fig. 1, while Fig. 6 shows a plan view of certain detail. A rotatable note holder comprises a transparent cross-shaped member 11 mounted on a spindle 12, the notes being held in clips 14. A sliding bar 17 operated by a handle 18 rotates the holder, the bar 17 being connected by a chain 21 to a toothed disc 20 freely mounted on the spindle 12. A toothed disc 19 is adapted to give a one-way drive to the note-holder, the return movement of the roller 20 being effected by a spring 25, a coiled spring 23 allowing axial movement of the disc 20. To lock the note-holder after rotation, the arms 11 abut against a spring-controlled stop 27, reverse movement of the holder being prevented by a spring catch 29. The locking means is released by a hand-operated lever 30, a pivoted gravity catch 32 engaging a pin 33 on the lever 30 to hold the mechanism unlocked until the machine has functioned. The arms 11 rock the catch 32 to release the lever 30 and allow the locking means to return to the operative position. The change in containers 37 is delivered to a receptacle 38, by the forward movement of a slotted tongue 39 mounted upon a spring-controlled sliding member 40 carried by a knife member 41, the withdrawal of which by the spring 42 allows coins to fall on the tongue 39. The sliding bar 17 and member 40 are moved by a rod 43 provided with a handle 18. On turning the handle, a pin 44 engages grooved projections 45, 46 on the member 40 and bar 17 respectively, the coin release slide and noteholder being actuated by drawing the rod 43 rearwardly. The release of the handle 18 returns the coin slide 40 and the clutch members 19, 20 to their initial positions. In a modification the sliding bar is formed as a rack and directly engages a pinion on the free part of the clutch. In operation the note is inserted in a clip held open by a stop 50 on the casing 51, the lever 30 is depressed, freeing the note-holder, the handle 18 is turned to engage the slide 40 and bar 17 and is then pulled out to rotate the note-holder and release the coins. The rotation of the handle releases a previously inserted note from its clip to a drawer, a projection 15 on the clip contacting with a stop 16. Separate mechanisms are necessary to deal with ten shilling and pound notes. Catches actuated from the sliding parts of the coin release mechanism move an indicator showing which coin mechanism has last been operated. A weighted flap in each shoot is held out of action by the weight of coins and locks the operating bar 43 when the shoot is empty.

Title: Process for the manufacture of solid metal fluoborates containing water of crystallisation
IPC: C01B35/06
Filed: 1957-08-02
Abstract: Metal fluoborates and particularly those of copper, cadmium, zinc and nickel, containing water of crystallization, are prepared by reacting with the metal itself or with a compound thereof such as the carbonate, oxide or hydroxide, a highly concentrated fluoboric acid (or hydronium tetrafluoborate) of which the water content is such that together with any water produced in the reaction it corresponds with the water of crystallization of the fluoborate desired.  The concentrated fluoboric acid may be obtained by reacting boric anhydride with liquid hydrogen fluoride or concentrated aqueous solutions thereof in a proportion of 1 mol. of B2O3 to 8 mols. of HF whilst maintaining the reaction between - 40 DEG  C. and + 20 DEG  C. Such a reaction is preferably effected in a polythene vessel containing concentrated fluoboric acid from a previous operation. Alternatively hydronium tetrafluoborate reactant may be prepared by reacting boron trifluoride hydrate with anhydrous hydrofluoric acid in a mol. ratio of 1:1 to obtain HBF4.H2O with a melting point of 50 DEG  C.  The fluoboric acid or the hydronium tetrafluoborate thus produced may be reacted to form solid metal fluoborates.  Aqueous 1.35 mol. solutions of the fluoborates produced have a pH of 1 to 1.7 and the pH may be raised by the addition of the corresponding metal borate to the solution of the fluoborate or alternatively, by selecting a suitable mol. ratio of the initial reactants, a crystalline metal fluoborate containing by-product hydroxy fluoborate and borates may be produced having a higher pH.  According to a typical example, concentrated tetrafluoboric acid was placed in a cooled vessel and boric anhydride and hydrofluoric acid were introduced alternately in small quantities whilst maintaining the temperature at 40 DEG  to 70 DEG  C.  The concentrated fluoboric acid so produced was reacted with zinc carbonate; on cooling to room temperature the mass solidified to crystalline zinc fluoborate hexahydrate.  Zinc oxide might be similarly employed.  The zinc fluoborate contained zinc hydroxy fluoborate and zinc borate so that a 1.35 mol. aqueous solution thereof had a pH of 3.  Further examples relate to cadmium, nickel and copper fluoborate production, and to the production of the fluoboric acid reactant by treating BF3.H2O with gaseous or aqueous hydrogen fluoride.
