Patent GB-2190738-A (GB)
Title: Heat pump system
Inventor: TRIPP BENJAMIN ALFRED
IPC: F24D11/02
Filed: 1987-02-24
Abstract: An all weather, year-round heat pump system for northern climates incorporates a containerless in-earth heat storage means comprising a compact nest of small bore pipes buried in a trench or pit. The heat circulation fluid comprises an anti- freeze mixture and is operated in winter, even under the most demanding circumstances within a few degrees of the freezing point of water. A solar energy collector, owing to the controlled temperature operates without ice build-up on the collector. The heat storage means builds an icy mass about the pipe nest as heat is extracted, so that a very large amount of heat is available from a relatively small installation requiring little ground area, due to the utilization of the latent heat of fusion. <IMAGE>
Patent GB-2191313-A (GB)
Title: Temperature control
Inventor: AOKI KAZUMI
IPC: G05D23/24
Filed: 1987-05-28
Abstract: A temperature control apparatus for use in a vending machine having a plurality of storage chambers includes a refrigerating apparatus provided with a plurality of evaporators (3a, 3b, 3c-Fig. 5) which are connected in parallel and disposed individually in the storage chambers. A plurality of electromagnetic valves 10a, 10b, 10c are coupled in series with the evaporators to control the inflow of the refrigerant. The operation of each electromagnetic valve, i.e. the temperature control in each storage chamber, is controlled by comparing at 60 the output in V02 of circuit 40 representing the average temperature of the storage chambers with actual temperature in each chamber represented by V1, V2 or V3. The operation of the electromagnetic valves are also controlled by comparison at 70 of a desired temperature with the actual temperatures in the chambers. The comparators 60, 70 are connected to a driving circuit 90 formed by an array of A-D gates 91, which drives the valves 10, and an OR gate 92 which drives a blower 8 and compressor 9 of the refrigerating apparatus. The comparator 70 may alternatively be used in a heating mode to control operation of heaters 5a, 5b, 5c in the chambers to raise their temperatures to a desired level. <IMAGE>
Patent GB-2193259-A (GB)
Title: Extract energy from the wind
Inventor: GERMIJNS DENISE MYRIAM JULIANA
IPC: F03D1/04
Filed: 1987-06-22
Abstract: Wind blowing through a tube- system 9 generates a secondary airstream 7 from which energy can be extracted by an air motor 6. The tubes have gradually increasing or decreasing flow cross-sections, whereby the dynamic pressure of the wind flowing through the tubes produces greater or less static pressures at different points along the tubes. A secondary airstream is then induced between these points or between the points and the ambient, through a branch pipe 10 and the air-motor 6, e.g. a piston machine, to deliver the desired power. The energy yield, per unit of the front surface which is directed to the wind, can be improved by giving the flow-through tubes polygonal cross-sections, bends and/or a relative positioning which results in a volume reduction. The tubes may be connected in parallel and/or series with respect to the wind flow therethrough. The spacing 8 between adjacent ends of series-connected tubes may be adjustable, a flexible seal 14 allowing such adjustment to be achieved. <IMAGE>

Furthermore the ski-board 10 also includes longitudinally extending snow gripping gullies 16 on the underside of the ski- board, the concentration of which is greater towards the rear of the ski-board providing for better manoeuvrability by shifting the body weight (Fig. 2). <IMAGE>

Patent GB-2222535-A (GB)
Title: Filter assembly
Inventor: HUNTER SUSANNE PHYLLIS
IPC: B01D46/44
Filed: 1988-09-09
Abstract: A filter assembly comprises a cartridge (18) containing a filter or a body of adsorbent material and a filter head (17) into which the cartridge (18) is fitted. The cartridge (18) has an inlet port defined by spigot (22) and a body (24) of porous material in the spigot (22) that can trap liquid droplets entrained in a gas stream entering the head (17). The body (24) of porous material is impregnated with a dye responsive to the presence of liquid trapped by the trapping means by changing colour, as is a wick (26) communicating therewith. Colour change at the wick (28) is viewed from outside the filter head (17) through lens (30). By this means the presence of droplet contamination in the gas stream e.g. by reason of an abnormality upstream of the filter head (17) can either be made visible directly from outside the housing or can be detected by remote sensing means. The invention is particularly, but not exclusively, applicable to the detection of oil mist or droplets in an air stream from a compressor.
Patent GB-2223942-A (GB)
Title: Fire damper
Inventor: PRESTON NEVILLE
IPC: A62C2/14
Filed: 1988-09-07
Abstract: A fire damper for location in ducting, having a metal shutter mounted in a housing, normally retained in a folded condition but loaded towards an extended condition across the housing, has an operating mechanism for folding the shutter after release, operable externally of the housing. Thus, re-folding of the shutter after maintenance testing is facilitated. In one embodiment the operating mechanism comprises a winding handle 41, for winding a shaft 42 on which are mounted a ratchet wheel 48 and two reels 50, 52, for steel bands 54, 56 secured to the leading element of the shutter. In an emergency condition a pawl is disengaged from the ratchet wheel 48 if a fusible device 80 releases it. For maintenance testing the engineer may lift the pawl from the ratchet wheel 48 to test the shutter release operation, and replace it prior to operating the winding handle 41 to re-fold the shutter. <IMAGE>

Title: Shuttered electrical socket
Inventor: CHEN YUNG-CHIA
IPC: H01R13/453
Filed: 1989-05-17
Abstract: At present the possibility of an electric shock arises through the easy access of the electrical contacts in an electrical socket. Thus, an electrical socket having two electrical contacts 2, a housing base 4, a shutter base 6, two interlocking shutters 8 and a housing top 10 is disclosed. The shutters 8 interlock (see figure 2) such that simultaneous insertion of a pair of pins of an electrical plug is required to enable the shutters 8 to slide aligning holes 36 to reveal the respective electrical contacts 2. Insertion of a single pin slides one shutter (8) via a chamfer (34) to reveal and engage the pin with only a blind groove (38) in the other shutter and to thus block sliding of the other shutter by a later inserted second pin. The shutters are spring-returned by arms (40). The electrical socket also includes a pair of resilient ribs 20 disposed adjacent each electrical contact 2 for improving the contact force and to reduce metal fatigue. <IMAGE>

Title: Process and apparatus for the simultaneous production of olefins and catalytically cracked hydrocarbon products
Inventor: SERRAND WILLIBALD
IPC: C10G9/20
Filed: 1990-07-02
Abstract: An alkane-containing feedstream is passed through one or more tubes, which may contain alkane-dehydrogenation catalyst, immersed in a bed of fluidized particles. The bed is at an elevated temperature which maintains the temperature within the tube(s) at an alkane-dehydrogenation temperature. The particles may be inert, chemically active and/or catalytically active. In one embodiment, cracking catalyst particles are circulated beween a reaction zone (wherein they contact a cracker feedstock which is converted to cracked hydrocarbon products) and a regenerator (22) (wherein carbonaceous deposits on the catalyst particles are exothermically removed by contact with an oxygen-containing gas (24)). Hot regenerated particles from the regenerator (22) are recirculated (27) to the reaction zone for re-use therein. At least some of the circulating cracking catalyst (33) is passed in indirect heat-exchange relationship (42) with an alkane-containing feedstream (44) within a tube (42) whereby alkanes are endothermically dehydrogenated (e.g., to olefins) and the cracking catalyst is cooled. Preferably, the tube (42) contains a dehydrogenation catalyst, and the latter may be circulated between an alkane-dehydrogenation zone (42) and a catalyst re-activation zone (61). In the latter zone, carbonaceous deposits are exothermically removed by an oxygen-containing gas.
