Title: Improvements in or relating to absorption refrigeration systems and their method of operation
IPC: F25B15/06
Filed: 1956-12-19
Abstract: 802,773. Refrigerating. CARRIER ENGINEERING CO., Ltd. Dec. 19, 1956 [April 30, 1956], No. 38707/56. Class 29 In continuous cycle absorption systems preferably of the type described in Specifications 641,712 [Group X], 698,309, 787,298 and 800,249, a U-shaped coil 5 is provided in the evaporator 4 for the circulation of a secondary cooling mediium. In winter operation, the supply of cooling water to the condenser 9 and absorber 3 is stopped and the solution, on entering the absorber from the generator is flashed. The vapour rises into the evaporator 4 and condenses on the coil 5 thus heating the medium therein. The condensate can also be circulated as a heating medium from the evaporator by pump 32, but if the condensate is not required for heating it can pass to the absorber through overflow 55. In a modified form, Fig. 3 (not shown), the coil 5 can have steam passed through it in winter so that the water circulated by pump 32 from the evaporator to the load is heated.
Patent GB-1348905-A (GB)
Title: Assembly for attaching a boring tool to a drilling machine including a safety device to minimise tool breakage
IPC: B23B31/107
Filed: 1971-08-18
Abstract: 1348905 Machine tools O BILZ 18 Aug 1971 [5 Sept 1970 15 Jan 1971] 38714/71 Headings B3C and B3B To prevent axial back-pressure due to increased cutting resistance on a boring tool 25 from exceeding the pre-set axial feeding power of the driving machine, the tool spindle 2, 3, 4 of a machine tool assembly is axially slidable within a blind bore of the machine spindle 1 and connected thereto by means of a spline 24 and spring-loaded balls 15, held between pressure rings 13, 14, engaging a groove 18 in the tool spindle. Under normal conditions of feed, the spindles move axially together, but when the tool 25 encounters an abnormal resistance, the axial back-pressure forces the balls 15 out of groove 18 against the action of the spring 16 and the tool spindle slides deeper into the bore of the machine spindle 1 and thus prevents damage to the tool. The value of the back-pressure at which this occurs depends on the spring force which is pre-set by screwing retaining sleeve 11 on spindle sleeve 10. At the end of the operation when the tool is retracted from the workpiece any abnormal resistance to retraction is also accommodated by the tool spindle which again moves relatively to the machine spindle but in the opposite direction. In another embodiment, Fig. 3, the blind end 32 of the machine spindle bore contains a compression spring 26 which urges the balls 15, when the tool is out of work, to engage the top edge of a wider groove 18. In use the normal back-pressure on the tool spindle causes the balls to engage the bottom edge of the groove so that an electronic switch 30 is activated by a flange 27 on tool-spindle part 2 thus switching on the machine. In the out of work position the switch 30 faces space 28 and the machine is switched off as it is when in the overloaded position when the switch faces space 29. In Fig. 1 a device for indicating when the tool is overloaded comprises a coloured, reflective or radio-active ring 21 which is uncovered, or alternatively covered, by, for example, extension 19 of sleeve 11. The radio-active ring may be used to trigger a Geiger tube 22 and thence switch off the machine.

Abstract: 836,731. Electro - deposition of metals. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 27, 1956 [Dec. 30, 1955], No. 39300/56. Class 41. A process for the electro-deposition of a layer of a metal upon a conductive cathode surface is characterized in that a mass of an inert absorbent material is wetted with a solution of the metal to be deposited and is sandwiched between an anode and the cathode surface, a current is passed from the anode to the cathode through the said mass to effect deposition of the desired layer and the mass of inert absorbent material is washed to remove solution from it whilst the current is continued. The process may be used for depositing layers of rare metal (i.e. metal in short supply) such as zirconium, masurium, rhenium, and all elements heavier than bismuth, and also radio-active metals such as F e 55, Zn<SP>59</SP>, Au<SP>195</SP> and enriched isotopes such as Fe<SP>54</SP>, Cu<SP>65</SP> and Ag<SP>109</SP>. Suitable inert absorbent materials are gels, such as silicon. dioxide, pectine, hydrated starch and gelatine, and also filter paper, asbestos layers, porous sintered ceramic material and glass fibres. The anode may be of graphite or a rare metal. The metal layer may be deposited not only on metals hut also on synthetic resins which have preliminarily been covered with an electrically conductive layer consisting, e.g. of graphite or silver. As shown, a gelatine layer 1, wetted with a solution of Fe<SP>55</SP>Cl 3  in hydrochloric acid is provided on graphite anode 2 secured to metallic electrode 3. Copper plate 4 of size and shape similar to that of the upper surface of layer 1 constitutes the cathode and is secured to electrode 5. Cathode 4 is pushed against layer 1 by handle 6 and a voltage is applied between anode and cathode. Subsequently the anode, cathode and layer 1 with voltage still applied are sprayed with water from tube 10 through apertures 11. Spraying is continued as the electrodes are separated, the separation stopping the current flow. The waste water 12 is collected in vessel 14 through aperture 13.
