Title: Refuelling surge boot
Inventor: BROWN EUGENE W
IPC: B29C69/00
Filed: 1989-12-08
Abstract: A double-walled tubular bladder (82) is contained in a tubular casing (24) mounted between sections (20, 22) of a fuel line. The casing (24) has an outer shell (26), an inner shell (28) and end caps (30, 32). The inner shell (28) has a plurality of openings (80) for communicating fuel pressure to the bladder (82) which contains a compressible fluid so that the bladder (82) may be contracted by a shutoff shock in the fuel line to alleviate this shock. The bladder may be made by wrapping an inner ply on a cylindrical mandrel, inserting the inner ply and cylindrical mandrel in a tubular mandrel, wrapping an outer ply on the tubular mandrel, and joining the ends of the outer ply and the inner ply. The outer ply is cut diametrically so that the bladder can be pulled off the tubular mandrel and cut edges of the outer ply are spliced and the bladder placed in a mould for vulcanization. <IMAGE>

IPC: F24D11/02
Filed: 1990-02-05
Abstract: With reference to Figure 3, the sloping roof 250 of a building 10 incorporates inner and outer juxtaposed metal panels, 15, 16 spaced from each other to define passageways 20 which serve as heat exchangers. A closed-loop water circulation system 18 connects the passageway 20 with low, medium and high grade heat store chambers 21, 23, 25 disposed within the building foundation structure 13. The water circulation system 18 employs sub-systems 22, 29 and 31 which comprise, respectively, primary, secondary and tertiary sub-systems. The heat store chamber 21 comprises a portion of the primary circulation sub-system 22 whereby water is re-circulated through the panel passageways 20 so as to be raised in temperature by solar neat. In addition to the heat store chamber 21, the primary sub-system 22 comprises a heat pump unit 27. The secondary water circulation sub-system 29 conveys water in a closed loop which, in addition to the heat store chamber 23, comprises the passageways 20 and the heat pump unit 27. The tertiary water sub-system 31 comprises the heat store chamber 25, radiators 19, underfloor heat exchanger coils 35 and a heat exchanger coil 37 incorporated in a hot water cylinder 39. Heat from water flowing in the primary sub-system 22 is given up to the heat store chamber 21 and also to the heat pump unit 27. Heat from water flowing in the secondary sub-system 29 is given up to the heat store chamber 23, as well as to the heat pump unit 27. A controller 40 is operable to provide controlled transfer of heat between the sub-systems 22, 29, 31.

Title: Injection pump for fuel supply to an engine
Inventor: ROESGREN CARL-ERIK
IPC: F02M63/00
Filed: 1990-08-29
Abstract: An injection pump comprises a cylinder element (1) defining a cylinder bore (6) into which open an inlet duct (3), and an outlet injection duct (7), a plunger member (2) being reciprocatingly movable within the bore (6) to compress fuel in a pressure space (11) for delivery via the injection duct (7) for instance into a cylinder of an internal combustion engine.

Title: Electric motor control of a floor cleaner
Inventor: KUMAKI NOBUYOSHI
IPC: H02P1/26
Filed: 1990-10-11
Abstract: An electric floor cleaner is driven by a three-phase motor, whose rated voltage is substantially equal to a voltage obtained by voltage doubling and rectifying at 11 a single-phase power line and then by converting a voltage doubled d.c. voltage into three-phase a.c. by an inverter 12. The voltage and frequency of the three-phase a.c. output from the inverter are controlled for a predetermined period of time after a power switch is put into a turned on state from a turned off state so as to provide a soft start. It is therefore possible to reduce the starting current to a small value enabling the use of a larger rated output motor than a motor in a conventional system within an allowable current limit of a commercial power line. <IMAGE>

IPC: B65B25/20
Filed: 1990-11-23
Abstract: A process for cartonning a foldable article, eg. socks, briefs, panties, comprises the steps of mechanically winding-up the foldable article to form a roll and subsequently mechanically inserting the roll into a carton. The article, eg. briefs, partially folded, is wound-up on a motor-driven shaft 60 cooperating with a pivotable gripper rod 63 rotatable therewith, the wound article being pushed off the shaft by a plate 70 into an open-ended compression channel 80. The latter is closed at its open side by the plate when extended and an end piston 91 ejects the wound article from the channel through an opposite end chute assembly 81 comprising inwardly biassed pivoted plates 102 into a carton. A cycle of the machine is initiated by proximity sensors 57, 59 which sense the operator's hands laying the articles onto the winding shaft, completion of the winding being sensed by a sensor 58 which signals a microprocessor to stop the motor and initiate the remaining machine cycle. A carton end-folding assembly 200 comprising reciprocable clamping fingers, lid flap folding rake 110, side folders 115, and lid-folding flap 114 is provided. <IMAGE>

Title: Fail-safe valve actuator
Inventor: AKKERMAN NEIL HOOVER
IPC: F16D43/22
Filed: 1991-04-15
Abstract: A valve actuator has an electric motor 50 driving a nut 20 on valve stem 18, via gear train 58-66 and a combined centrifugal clutch and torque limiting device 56, to move the valve and compress spring 28. When a disc 36 on valve stem 18 abuts stationary shims 42, the torque limiting device disconnects motor shaft 54 from a drive shaft 57. The valve is held open, against the closing force of the spring by a one-way clutch 100, which is locked by a pin (110, Fig 6) held in a groove (104) by a solenoid 106 against the action of a further spring. When power fails the solenoid releases the pin and the valve returns to its fail-safe condition under the action of spring 28. The return motion of the valve and gear train in damped by means of a centrifugal brake (116, 118, Fig 6) (300, 302, Fig 14). The centrifugal clutch prevents the torque limiter from operating under the high torque associated with starting of the motor. <IMAGE>

Filed: 1991-07-03
Abstract: A method and apparatus for inhibiting the damage to buildings and other structures produced by shrinkage of naturally occurring peat or clay layers below the ground comprises a water delivery system to deliver water from a supply to the shrinkable layer to inhibit shrinkage thereof. The water is supplied at intervals throughout the life of the building to inhibit shrinkage. Preliminary assessment of the depth of the shrinkable layer is carried out by taking core samples. The liquid delivered comes from supply means for the purpose eg the water main or a storage tank into which waste domestic washing or rinsing water and/or rain water is fed. The delivery conduits are open-ended, delivering direct to the shrinkable layer at spaced locations around the building. A manifold connects the upper ends of the conduits. Control means provides more liquid in dry conditions than at wet times.
