Title: Three-pipe air conditioning systems
IPC: F24F3/10
Filed: 1964-11-16
Abstract: 1,085,126. Heating and cooling buildings; air conditioning. SULZER BROS. Ltd. Nov. 16, 1964 [Nov. 19, 1963], No. 46604/64. Headings F4U and F4V. A three-pipe air conditioning system having hot and cold water supply lines to room unit heat exchangers includes by-passes leading water from the hot and cold lines downstream of the units to the water heater and cooler respectively. As illustrated, pumps 20 pass water from the heater and cooler 9 and 10 to hot and cold headers 21 and 22 and thence via hot water lines 40 and cold water lines 41 to room units 8 of various building zones N, E, S, W, the supply of water to the individual units being controlled by three-way valves 53. Return lines 46 pass water into hot or cold water return lines 63, 64 according to the setting of three-way valves 66 controlled by temperature sensors 65 in the return lines 46. By-passes 55 and 56 lead hot and cold water from the lines 40 and 41 downstream of the units 8 to headers 57 and 58 connected to the hot and cold return lines 63 and 64. The by-passes have throttle elements 59 and 60 allowing adjustment to compensate for different flow resistances in the buildings. In each zone a pressure difference controller 44 acting through a relay 47 adjusts a hot water line valve 42 to maintain a constant pressure difference between that line and the return line 46, and a pressure difference controller 45 acting through a relay 48 adjusts a cold water line valve 43 to maintain the pressure difference between that line and the return line 46 at a set value determined by external sensors 49 and 50 responsive to solar radiation and external air temperature respectively. The heater 9 is heated by a heat exchanger connected by lines 23 and 24 to a boiler, and heat is extracted from the cooler 10 by an intermediate water circuit having a pump 36 and given up to the evaporator 30 of a refrigeration circuit. The intermediate water circuit temperature is maintained constant by means of a cooler by-pass 37 operated by a valve 35. Heat is removed from the refrigeration condenser 28 by a circuit including lines 31 and 33 which are shunted by heat exchangers 68 and 69 in the hot and cold water return lines 63 and 64. Air treatment.-The room units 8 are of induction type having secondary air heat exchangers fed by the three - pipe system, primary air being supplied by a blower 2 from a central station 1. The latter includes mechanical and/or electrical dust filters 3, a preheater 4, a scrubber and humidifier 5, a cooler 6 and a heater 7, each of which may be wholly or partly by-passed. The air heaters and cooler derive heat from the heater 9 and give heat up to the cooler 10 respectively, and a thermostat (not shown) maintains the air temperature immediately downstream of the preheater 4 at at least 2‹ C. Water for the humidifier 5 is heated by a heat exchanger 70 connected in the return line 63 to the heater 9.

Abstract: 1,160,266. Applying colouring material to adhesive surfaces. DUNLOP CO. Ltd. 19 Oct., 1966 [3 Nov., 1965], No. 46668/65. Heading B6C. [Also in Division B2] A method of applying flock, e.g. of nylon, to a base sheet, e.g. of unvulcanized rubber coated with an adhesive, e.g. latex rubber comprises positioning the base sheet 6 between one electrode 3 maintained at a high potential and another 2 maintained at a low or zero potential and depositing flock, e.g. from hopper 1, under the influence of the electrostatic field potential between the electrodes, one or more lengths 4 of metal conducting wire at high potential being positioned with respect to the electrodes so that the electrostatic field is modified resulting in the desired selective distribution of flock on the base sheet. The lengths of conducting wire may be attached to the high potential electrode, positioned between the two electrodes or on the side of the high potential electrode remote from the low potential or earthed electrode and separately connected to a high potential source. The high potential electrode may be an endless electrode, the lengths of conducting wire being attached to said electrode and travelling at the same speed as the base sheet. In an embodiment, the base sheet may move continuously through the electrostatic field between the electrodes during flocking. In a further embodiment, following selective application of flock, the wire conductors are deactivated or removed and further flock applied. In a further embodiment, the base sheet is passed continuously through the electrostatic fields of two electrode assemblies, pneumatic extractors being situated after each assembly, the flocked product then being passed through a drying unit.

The solid ankle, cushion heel foot of Fig. 1 has a strip 3 extending into toe 2B and connected to centre portion or keel 1 by plugs 4 of the keel material entering inverted frusto-conical holes 4A in the strip. End face 4B is inclined rearwardly and upwardly to key it into keel 1. A softer outer portion of a self-skin forming kind of rigid plastics foam with an integral cushion heel 2A and toe 2B is foamed around the assembly of keel and strip. The embodiment of Fig. 2 incorporates a solid heel. The upper part of keel 5 is stepped at 5A, 5B, 5C to form a seating for a thin vacuum-formed plastics shell 8 which encloses rubber buffers 6A, 6B and pivot 6 which co-operates with inverted U-bolt 9 to form a uni-axial ankle pivot. Shell 8 is open at its bottom, and at its top 5D to fit around cosmetic fairing 7B. Toe 10, of the same material as keel 5, is connected to the latter by strip 11. The gap between toe and keel is filled by an expanded polyethylene cushion 13. In manufacture, keel 5 and toe 10 are foamed in a mould onto strip 11 and the assembly bonded to shell 8. An expanded polyethylene flexible sole 13A is attached to the underside of keel 5, the whole foot then being enclosed in a polyvinyl chloride cover 14. The embodiment of Fig. 3 (not shown) does not include a separate sole, shell or cover. In manufacture, the strip is located in a mould and the keel and toe foamed onto it. The assembly is located in a second mould and a cover (15) foamed around them. The keel is cut back at the heel (17) so that the cover may be thickened in this region to form a cushion heel (15A).

Abstract: 1,189,739. Two-part couplings. NORTHROP CORP. 4 Oct., 1968, No. 47261/68. Heading H2E. In a two-part electric coupling with a quickrelease locking mechanism, electrical connection is provided by pins 26 in a female housing 18 and sockets 24 in a male housing 19, the housings being locked together by hooks 47 attached to housing 19 being forced inwards to engage a thread 28 on housing 18 by a camming surface 52 in a sleeve 48, which is slidable towards housing 18. Hooks 47 are integral with a split cylinder 39 fitting tightly around, housing 19 and having a flange engaging a groove in housing 19 at 44. Hooks 47 are located in grooves 53 in sleeve 48 so that, in the locked position, rotation of the sleeves forces hooks 47 to move along the thread 28, thus producing a more or less tight connection. A groove in housing 18 and a ridge 34 on housing 19 provide location for the electrical contacts. Moulded elastomeric inserts 22, 23 and a sealing ring 57 prevent moisture ingress.

Filed: 1974-11-08
Abstract: 1517286 Power assisted brake pedal assemblies GIRLING Ltd 28 Oct 1975 [8 Nov 1974] 48509/74 Heading F2F A brake pedal 1 is pivoted at 4 to an upper lever 7 and connected at 2A to the master cylinder 3, and a power assisted device 11 is pivotally connected to lever 7 at a point 6 such that the force applied to the pedal 1 is substantially in line with that applied by the pedal to the master cylinder. When power assistance is applied the pedal 1 and lever 7 together pivot about a fixed pin 8 and in the event of power failure lever 1 pivots about a pin 4 to increase the pedal ratio. Pin 4 provides a pivotal connection between pedal 1 and a link 5 which at its other end is connected by pivot pin 6 to lever 7; pin 4 extends into a slot 9 in lever 7. A spring 15 urges pedal 1 and link 5 together and a weaker spring 16 urges the link 5 and lever 7 apart. Pin 6 bears on pedal 1. In operation, initial foot pressure causes pedal 1 to pivot about pin 6 causing pin 4 to move along slot 9 so that link 5 pivots a lever 13 to open a valve 12. Hydraulic fluid is thereby supplied to device 11. The movement of lever 7 (together with pedal 1) during power operation tends to move pin 4 forwardly in slot 9 to close valve 12 so that the position of the pedal and the force applied to the master cylinder are dependent on the manual force applied to the pedal. In the event of power failure the initial movement is the same but when pin 4 moves rearwardly in slot 9 the pedal pivots about that pin. In a modification (Fig. 3, not shown) the power assisting means operates by vacuum and pulls the pedal 1.

Filed: 1971-10-20
Abstract: 1342373 Pneumatic conveyers FREE-FLOW PACKAGING CORP 20 Oct 1971 [2 Nov 1970] 48708/71 Heading B8A In a system for distributing lightweight particulate material, e.g. expanded polystyrene particles, from a hopper 14 to a series of distributing points 18, the hopper is connected to a venturi section 30 of a conveying duct 16 by way of a screened venting section 24 and each distributing point 18 is closable by a valve 40 and has a screened venting section 38 of an area greater than that of section 24. In operation, with the valves 40 closed and the screened sections 38 filled with particulate material, air from a blower 20 passes into the venturi 30 and since the system is in a state of rest, creates an area of high pressure in the region of the hopper outlet to retain the material therein, the air being dissipated through the screen section 24. When a valve 40 is opened to discharge the material stored in the respective screened section 38, the material on being discharged will uncover the screened section 38 and thereby cause an air flow from the blower to the respective screened section. The said air flow through the venturi creates a vacuum to draw material into the air flow to replace that discharged from the screened section. As soon as the air flow through the screened section 38 is prevented once again by material therein the system reverts to its "rest" condition. The system has a plurality of distributing points 18 and the branches connecting successive distributing points 18 are arranged at an angle to the main duct to ensure proper distribution, Figs. 6, 7 (not shown). In a modification Fig. 9 (not shown) the junction of the branch with the main duct is formed as a venturi to ensure correct distribution of the material. The venturi 36 at the outlet of the hopper is provided with clamps (80) Fig. 5 (not shown) whereby to adjust the crosssection thereof to suit the system.

As shown, Fig. 1, a thermopile 10 comprises three rows of thermoelectric devices connected electrically in series, each row comprising a plurality of layers 32, 34 of N and P-type thermoelectric material connected in series by fin structure 24 and upper and lower rows of blocks 12 which may be of aluminium or copper. The layers 32, 34 are arranged so that the blocks 12 are heated and the fin structures 24 are cooled. Blocks 12 have aligned bores 14 for a cooling liquid, and the bores of adjacent blocks are connected in series by bellows members 46 which may be of a material having a relatively high electrical resistance (defined) such as certain specified alloys. The fin structures 24 each comprise two base members 26 connected by fins 28 which cool the air flow between them. The layers 32, 34 of thermoelectric material each comprise a plurality of pellets of bismuth telluride soldered or brazed to the adjacent surfaces of blocks 12 and base members 26. The blocks 12 at the ends of each row have tubulations 52 which receive the ends of insulating conduits 50, 54, 56, 58 which connect the bores 14 in series to provide a cooling circuit for the hot junctions. The three rows of devices are mounted between two plates 60 which have grooves 62 to locate the rows of blocks 12 and are clamped together by tierods 66. Plates 60 may be of insulating material or else of metal provided with insulating linings 64 for the grooves 62. In a modification, Figs. 2 and 3 (not shown), the straight fins (128) are more widely spaced and the gaps are filled with corrugated fin structures (132), the top and bottom faces of the blocks (112) are cylindrical and the grooves in the plates (106) are correspondingly shaped, there are only two rows of thermoelectric devices, and the tie-rods (104) are located between the two rows. In an additional modification, Fig. 5 and 6 (not shown), the fin structures are replaced by metal blocks (220) which have aligned bores (226) through which a liquid to be cooled is passed. The aligned bores (218, 226) in both the heated and cooled blocks are joined by members (228) each comprising a short ceramic tube (230) of aluminium oxide or beryllium oxide which is connected to the adjacent blocks (210, 214, 220) by bellows-shaped tubes (232) of aluminium or copper. A similar connecting member, Fig. 4 (not shown), is described for use in the embodiments of Fig. 1, and Figs. 2 and 3. In any of the embodiments the heated and cooled liquid or air flows can be interchanged by reversing the current, and the device may also be used for voltage generation.

The platform shown in Fig. 1 has six balloons and skirts, inflated by ejectors supplied with compressed gas from bottles 107. The balloons are inflated during the descent and the skirts automatically on impact, for example by ground-sensing electric elements in the base of each skirt, which open a valve connected to the bottles 107. The skirt may be supplied by two ejectors in series (Fig. 5, not shown), and provision may be made for connecting the ejectors to an external supply, e.g. to facilitate movement of the platform after landing. The relative sizes and inflation pressures of the balloons and skirts are such that the balloons collapse on impact and the skirts do not. The six skirts in the embodiment shown in Fig. 1 may be surrounded by a further skirt. In the embodiment of Fig. 6A, the conical external wall 15b of each balloon is continued to form a skirt 15a, the latter being supplied through a bellows 17. In other embodiments, the skirts and balloons are formed by toroidal inflatable bags, or by opposed truncated cones, whose walls are stiffened by having inflatable portions. The lower wall of the balloons may be perforated so that the skirts are inflated from the balloons and the balloons may have pressure relief valves so that they remain collapsed after impact.
