Title: Absorption machine
IPC: F25B15/00
Filed: 1972-09-22
Abstract: 1368869 Absorption refrigeration machines TRANE CO 22 Sept 1972 [24 Sept 1971] 44059/72 Heading F4H An absorption refrigeration machine comprises a first effect generator 10, a second effect generator 13, an evaporator 32, an absorber 27 and a condenser 21, and means whereby the machine may be used solely for cooling, or for heating and cooling simultaneously, or for heating alone. In operation as a refrigeration unit, valve 53 connecting the vapour passage between an auxiliary chamber 16 and the evaporator 32 is closed, and no flow of water is allowed through heat exchanger 18. Dilute solution is fed into the first effect generator 10 through conduit 48. The heat from boiler tube 11 causes the refrigerant in the solution to boil off and the vapour passes via passage 15, the partially concentrated solution being drawn off through conduit 49, heat exchanger 47, conduit 50 into the second effect generator 13. Vapour from conduit 15 passes into chamber 16, conduit 17 and into heat exchange coil 14. The heat from the coil 14 causes further boiling and thus concentrating of the solution. The vapour phase passes through eliminators 23 into the condenser 21, to be condensed by the cooling fluid in coil 24. The liquid is drawn off to the evaporator pump 29. The concentrated solution is removed from generator 13, and passes through heat exchanger 43 to the absorber pump 38. In the evaporator, refrigerant from-pump 29 pasess through spray headers 31 to cool water for a building air conditioning system in heat exchanger 33. For simultaneous heating purposes, water for heating the rooms may pass through the heat exchange coil 18 provided in chamber 16.  When the refrigeration machine is required entirely for heating purposes, solenoid 58 is activated to open valve 53. At the same time, the flow of cooling water through heat exchange coils 26 and 24 is ceased. Due to an equalizing of pressure in the second effect generator 13 and condenser 21, vapour ceases to flow through coil 14, all of the vapour produced in generator 10 passes via chamber 16 into the evaporator 32. Heat transfer takes place with the coil 33 thereby providing heated fluid for the building. Condensed vapour falls into the absorber 27 and mixes with the absorbent solution being sprayed from headers 36 to form dilute solution; which passes via conduit 39 back to generator pump 40 to be delivered back to the first effect generator 10. Concentrated solution produced in generator 10 passes through heat exchanger 47 into generator 13, and then via conduit 51, heat exchanger 43 to absorber pump 42 for delivery to the spray headers 36.

Abstract: A glass laser material consists of a silicate glass containing 0-10 mole per cent of a divalent metal oxide, e.g. CaO, SrO, BaO, CdO, or PbO, 7-20 mole per cent of an alkali oxide over half of which is one or more of K2O, Rb2O or Cs2O, 0.01-30 weight per cent of a lanthanide or actinide activator, e.g. Nd3+, Pr3+, Sm2+, Sm3+, Eu2+, Eu3+, U3+, Tb3+, Ho3+, Er3+, Tm3+, Dy3+, Yb3+, Ce3+, and mixtures thereof, the balance being uncontaminated by material causing light absorption at 1.06 microns wavelength.  Preferably the mole ratio of the alkali oxide to the silicon oxide is approximately 1:6.  A particular glass described has the mole per cent composition: SiO2, 84.5; K2O, 7.8; Rb2O 3.9; BaO, 2.4; Sb2O3, 0.3; Nd2O3, 1.1.  The glass may be prepared by heating in air at 1540 DEG  C. for one hour, cooling to 1480 DEG  C., casting and annealing.  The glass has a long fluorescent lifetime, thus increasing the energy which can be stored in the excited state and hence the power output for a pulsed laser. The glass also permits an increase over prior art glasses in the permissible concentration of activator before the onset of concentration of activator before the onset of concentration quenching.  Radiation occurs, using neodymium transitions from a 4F 3/2 energy state to either 4I 13/2 , 4F 11/2 or 4I 9/2 state, these latter states each being split by as much as 450 cm.-1.ALSO:A glass laser material consists of a silicate glass containing 0-10 mole per cent of a divalent metal oxide, e.g. CaO, SrO, BaO, CdO, or PbO, 7-20 mole per cent of an alkali oxide over half of which is one or more of K2O, Rb2O or Cs2O, 0.01-30 weight per cent of a lanthanide or actinide activator, e.g. Nd3+, Pr3+, Sm2+, Eu2+, Eu3+, U3+, Tb3+, Ho3+, Er3+, Tm3+, Dy3+, Yb3+ Ce3+, and mixtures thereof, the balance being essentially silicate and the whole being uncontaminated by material causing light absorption at 1.06 microns wavelength.

Abstract: 1467701 Automatic circuit breakers SACE SpA COSTRUZIONI ELETTROMECCANICHE 15 Oct 1974 [12 April 1974] 44584/74 Heading H1N An excess current responsive automatic circuit breaker has at least one pair of fixed and movable contacts 8, 10 and 9, 11 on respective parallel current carrying supports 2, 14 and 3, 15 arranged so that current through the supports tends to bias the contacts apart; this bias is opposed by a spring 27 acting on pivoted (at 17, 18) moving contact carriers 12, 13 through toggle arrangements including connecting rods 29, 30 pivoted to the moving contact carriers by pins 35, 36; supporting bracket 19 has slots 25, 26 for the ends of pins 23, 24 on which spring 27 acts and slots 37, 38 to guide the pins linking connecting rods 29, 30 and contact carriers 12, 13; the arrangement is such that when low currents are passed (via 2, 8, 10, 14 connecting strap 16, 15, 11, 9, 3), spring 27 overcomes contact opening forces caused by the current flowing, whilst overload currents force the moving contacts to rotate further about pivots 17, 18, the toggle arrangement moves over centre and then the bias of spring 27 reinforces the contact opening effect of the overcurrent. The circuit breaker is manually operable, lever 22 moving common supporting member 19 between the Fig. 1 and Fig. 2 (not shown) positions. An additional thermomagnetic contact opening device 7 is provided. Ferromagnetic plates 42, 43 are provided to split the arc. The arrangement is said to reduce contact bounce on opening.

A frame for tipping refuse bins 3 into a vehicle comprises swingable arms 1 provided with claws 6 to engage a stump or handle 7 of the bin and buffers 2 to engage the sides of the bin. The buffers 2 are pivotably mounted at 4 on the arms or have a curved surface so that the bin 3 can pivot relative to the arms 1 as they are swung about a shaft 10 in the direction 11 by a piston-rod 9. The claws 7 have guide slots 16 so that the pivotal movement of the bin 3 causes the stump to be locked therein as it becomes inverted into the position shown in Fig. 5. In operation the claws 6 engage the stumps 7, Fig. 1, and the arms continue to swivel until the buffers 2 engage the bin and inversion starts with the stumps becoming locked in the slots 16 while a stop buffer 18 limits the bin's movement. In modifications described the arms 1 are rotated by a cylinder acting through lever and abutment links on links attached thereto or by means of a toothed rack or pinion. The arms 1 are movable towards and away from each other on the shaft 10 to accommodate different sized bins by a piston arrangement and the buffers 2 are offset inwards to engage the side of the bin.
