IPC: F24F3/06
Filed: 1963-12-23
Abstract: 992,621. Heating and cooling buildings; heat pumps; air conditioning. TEMPERATURE Ltd. Dec. 23, 1963, No. 50747/63. Headings F4H, F4U and F4V. Water is circulated to a plurality of air conditioning units 3, heat being transferred from the water to the air or vice versa by reversible compression condensation refrigeration cycles in each of the units. The direction of refrigerant flow in each of the cycles is individually controlled either manually or automatically. Water is supplied to the units 3 through pipes connected in parallel to a supply line 2 and water from the units passes through a cooling tower 6 or by-pass 7, according to the setting of a threeway valve 5, and through a calorifier 1. Water from a thermostatically controlled boiler 10 heats the calorifier 1 or passes through a by-pass 12 according to the setting of a three-way valve 11. The valves 5 and 11 are controlled by a thermostat 13 to maintain the temperature in the line 2 constant. When the valve 5 passes water through the by-pass 7, a switch shuts off a cooling tower fan (not shown), and when the valve 11 passes water through the calorifier 1 a switch ensures that the boiler is operating. A shunt circuit 9 may be provided to supply heat to the water in line 8 from air extraction systems or as waste heat from plant in the building. Condensate from the units may drain through lines 16. Each unit has fresh and room air intake ports and a filter, and a separate ventilation system is provided to supply fresh air from a central plant either to the unit fresh air intakes or to the spaces in which the units are located through grilles separate from the units. The air may be filtered, washed and tempered by the central plant.

Abstract: 1,249,654. Stop motion. LEESONA CORP. 25 Oct., 1968 [27 Oct., 1967], No. 50751/68. Heading D1D. Strand forwarding apparatus comprising driven feed means, is provided with means which detects the winding of a predetermined quantity of yam on the feed means and in response causes the drive to the feed means to be interrupted. As shown yam Y is forwarded by a driven roller 14 and a co-operating belt 16 running over idlers 18. Roller 14 comprises an outer shell 36 carried by a core 34 axially slidable on a sleeve 24. An annular part 26 is, held fast on sleeve 24 by a screw 30 which also secures sleeve 24 on a driven shaft 20. Interengaging clutch members are formed on part 26 and core 34 the latter being lockable in either of two positions by a spring loaded ball 40 engaging one of two indents 44, 46 on sleeve 24. Normally ball 40 is in indent 44. so that the clutch members are interengaged and the outer part of the roller rotates with shaft 20. A blade 53 is mounted closely adjacent roller 14 so that should yam Y break and wrap onto the roller it comes into contact with the yarn being built on the roller and brakes the roller. The braking action on the roller causes the sloping clutch surfaces 48, 50 to move the outer part of the roller axially' of the shaft 20 so that ball 40 moves into indent 46 and the drive is interrupted. When the excess yarn is removed the outer part of the roller is moved axially by hand to bring it once more into driven engagement with the inner part.

The legs may be telescopic and are operated by piston and cylinder units 5 and 6. The legs may be secured in positions parallel to the longitudinal axis of the vehicle so that the latter can be towed while resting on the rollers. The rollers may be hollow and may be used to store fuel. The rollers or plates may occupy inclined positions during the drive stroke of the legs so that the vehicle is raised to reduce resistance to travel.

Each disc 2, 3 is perpendicular to the axis A and has an orifice 4, 5 positioned on the axis, alignment being indicated when the light beam is adjusted in direction to give a steady quantity of light through the orifices while the discs are rotated. In the preferred arrangement, Fig.5, the orifices 4, 5 are identical semicircles with the mid-point of each diameter lying on the axis A. Parallel Alignment. An apparatus similar to that of Fig.5 is used except that one of discs 2, 3 is rotated relative to the other through 180 degrees about axis A. Both discs are rigidly attached to tube 20 which is rotated by motor 24 and transmission 23 while a light beam of preferably circular cross-section is directed through the tube 20. If the beam is not parallel to axis A, a varying amount of light will be detected e.g. by a photomultiplier at the other end of the tube. The beam is thus changed in direction until a steady, low quantity of light is detected. Coaxial alignment. Having achieved parallel alignment, discs 2, 3 are arranged as shown in the Fig. and a parallel beam of light is directed through the tube. If the beam is not coaxial with the tube, a varying light output is detected so the beam is adjusted until a steady, low quantity of light is detected. The cylinder may be 15-20 cm long, the orifices may be 5-10 mm in diameter and the beam may be 2 mm in diameter. The tube may rotate at 100 r.p.m. Circular, square or triangular orifices 4, 5 may be used.

In an arrow type network (Fig. 1, not shown) an activity is represented by an arrow connecting a start and a finish event represented by circles. In a node type network (Fig. 2, not shown) the activity is represented by a box and the boxes are joined by arrows representing the precedence relationship between the activities. Two lists are created for the arrow type network, a first sequentially listing all activities by their ending event numbers and a second sequentially listing all acitvities by their beginning event numbers (Fig. 3, not shown). Then the first activities on both lists are compared for equality step 70, and, if they are equal, a precedence relationship is noted using a subroutine (Fig. 8, not shown). If they are not equal further subroutines (Figs. 5-7, not shown) are entered. Only one pass is made through the first list, each activity in the first list being compared with activities in the second list to establish all the precedence relationships. A known computer (Fig. 9, not shown) as described in Specification 1,375,917 is used and PERT, CPM methods, e.g. for shipbuilding or a business merger are mentioned.
