Title: Improvements in or relating to the Control of Thermal Conditioning Systems
Inventor: JACKSON THOMAS BRUCE
IPC: G05D23/20
Filed: 1967-02-24
Abstract: 1,193,711. Automatic temperature control systems. HONEYWELL Ltd. Feb. 16, 1968 [Feb. 24, 1967], No. 9080/67. Heading G3R. A system for heating or cooling providing a temperature in a space at a predetermined time comprises a timer for generating a set point signal which progressively approach a value representative of a determined temperature throughout an interval immediately preceding the determined time which signal is modified by a second signal representative of thermal conditions outside the space and means for comparing the modified set point signal with a signal representative of space temperature and producing an output signal when a comparison indicates two are equal, such output signal initiating operation of the system. The desired temperature at various periods during a day is represented by a dotted curve AJCD and the actual room temperature by a solid line curve ABCD. When the room temperature drops during say the night to point B the system cycles at this low temperature until point C is reached when a gradually increasing set point signal actuates a heating system so that at some determined time say 9 a. m. the determined temperature is reached in the room. The set point signal is derived from a resistor (8) Fig. 3 (not shown) which is positioned by a cam driven by a timing motor (9) the resistor forming one arm of a bridge circuit (2). A further bridge circuit includes an outside temperature sensor which modifies the set point signal so that it may follow, for example a dotted curve HD. When the outside temperature is higher as in these conditions the heat losses are smaller the room temperature may fall along a curve AE and heating will commence after point in time at E. The bridge circuit through an amplifier may operate a relay controlling a boiler and circulating pump but other types of heating systems e.g. ducted air with an electrical, oil fired or a gas fired source are envisaged. The system is also applicable to off peak electric storage heating systems in which the final temperature D may be arranged to be above a normal comfort zone as further energy is not available after the end of such off peak period. Switch on of such heaters is arranged to be earlier when the outside temperature is low. The signals may be represented by pneumatic as liquid pressure signals. During the day, the temperature may be maintained at a set value DA by thermostatic means (not shown) and the set point driven to a higher value HL than this by suitably shaping the cam.

Abstract: 998,150. Binding edges of non-metallic sheet material. ELITE FILING SYSTEMS Ltd. March 9, 1964 [March 7, 19631, No. 9097/63. Heading B5K. An edge of a document 2 is bound by bringing the document edge into abutting relationship with an edge of a strip 1 and applying an adhesive tape 3 to said edges on one side only to join them together. The document 2, e.g. a drawing, map, duplicate master or an offset litho-plate, is fed along the surface of a polished metal guide table 4 with the edge of the document engaging an upstanding guide 5. The non-adhesive strip 1 is fed from a roll 6 over a roller 7 to finely knurled compression and feed rollers 8, 9 so that an edge of the strip 1 engages a guide 10 in a plate closely situated to the end of the guide 5 to bring the two edges into abutting relationship. The tape 3, which is adhesive on one side only, is fed from a roll 11 over a roller 12 to the rollers 8, 9 where it is pressed over the abutting edges to join them together. A handle 13, Fig. 2, drives the roller 9 which drives the roller 8 through meshing pinions 14, 15. A knife blade 16 having a bevelled cutting edge is disposed transversely of the feed direction of the document 2 and severs the strip 1 and the tape 3. The blade 16 is movable downwardly about a pivot 17 against a coil return spring 18 to engage a slot 19, Fig. 1. To prevent the tape 3 from adhering to the roller 9 in the absence of a document 2, an interleaving tape (not shown) is supplied from a roll on a bracket 20 to pass over the roller 9 so that the tape 3 sticks to the interleaving tape. The table 4 can be adjusted transversely to the feed direction of the document 2 by bolts 22 fast with the table 4 engaging transverse slots in a support table 21, knurled nuts 24 securing the two tables together. A screw clamp 31, Fig. 2, is provided to mount the apparatus on a table (not shown). The strip 1 may be of tracing cloth, synthetic plastic, press-pahn, press-board or paper and the tape 3 may be transparent self-adhesive tape. The apparatus may be modified by omitting the reinforcing tape 1 and adjusting the table 4 so that the entire width of the tape 3 is applied to the document 2 and the edges of the document 2 and the tape 3 coincide.

Title: Improvements in or relating to the distillation of oil-bearing minerals
IPC: C10G1/02
Filed: 1950-04-14
Abstract: 683,713. Distilling oil shale &c. STANDARD OIL DEVELOPMENT CO. April 14, 1950 [June 16, 1949], No. 9282/50. Class 55 (i). Oil shale, oil sands, tar sands, &c. are distilled as a fluidized bed in a retort 10 by the heat of solid residues returned from a combustion chamber 40 in which they are burnt in fluidized form at a temperature yielding sufficient heat for complete distillation in the retort but not exceeding 1200‹F. nor more than 50‹F. higher than the distillation temperature. The combustion temperature may be about 900‹-1200‹F., with the circulation rate of the burnt shale below about 30 times the fresh feed rate. In this way the organic carbon content of the spent shale is reduced, and the content of carbon as carbonate may approach CO 2  saturation thus reducing adsorption activity in the retort. Fresh shale is introduced through a valved line 1 and fluidized by inert gas such as product tail gas, steam or CO 2  supplied through a line 12 and carrying hot solids in suspension from chamber 40. A mixture of freshly retorted and burnt shale passes through a line 22 into a stripper 30 operating as a second retort and thence into a line 35 for conveyance by air, &c., e.g. preheated to 600‹- 800‹F., into chamber 40 in which the fluidized bed temperature may be controlled as by a cooling coil 42 or a partial circulation of solids through an external cooler. Solid residue is withdrawn through line 55 to line 12. Specification 586,992 is referred to.

Title: Improvements relating to regenerative heat exchangers
Inventor: HODGE JAMES
IPC: F28D19/04
Filed: 1951-04-24
Abstract: 702,158. Regenerative heat-exchangers. POWER JETS (RESEARCH & DEVELOPMENT). Ltd. April 18, 1952 [April 24. 1951], No. 9563/51. Class 64(1) Relates to regenerative heat-exchangers comprising a matrix 4 of heat-transfer material through which fluids between which heat is to be exchanged flow in separated streams, seals 8 bearing frictionally against the matrix and defining the duct area for one of the fluids, and means for effecting relative rotational movement between the matrix and the seals so that the seals sweep a circular locus over the matrix surface whereby different parts of the matrix are successively traversed by each fluid. According to the invention, relative oscillatory motion is provided between the seals 8 and the matrix 4, said motion having a component in a direction radially of the matrix. Figs. 1 and 2 show the application to apparatus having a rotating matrix the heat storing portion of which comprises for example a pack of tubes 5. The seals 8, which are made of self-lubricating material, are spring urged against the matrix face and are connected to cold gas ducts 7 by bellows 10 permitting relative lateral movement between the seals and the duct. The matrix shaft 6 has fixed to it two pinions 12 each of which engages with and drives an internally toothed annulus 13 which rests on and is supported by the pinion. The outer rim of each annulus is eccentric to its rotational axis and each seal 8 has an internal extension 14 which rests on the outer rim of the adjacent annulus. Thus as the annuli 13 rotate by their engagement with pinions 12, the seals 8 will be given an oscillating movement radially up and down across the matrix face. This oscillating movement is guided by rods 17. 18 the ends of which are slidable in sockets 21 in the heat exchange casing 1, springs 20 serving to return the seals positively after each upward movement. The heating gas flows through the space 9 outside the cold gas ducts 7 and a labyrinth seal 11 is provided to prevent gas from by-passing the matrix. In a further arrangement. Fig. 3, the seals 8 are pivoted at 22 and the oscillatory motion is provided by an external crank or eccentric 23. Alternatively. the frictional drag of the matrix may move the seal 8 about its pivot until it is returned to its original position by a spring, Fig. 4 (not shown). Fig. 5 shows the application to apparatus having a non- rotary matrix, the ducts 7 sweeping in a circular locus across the matrix face. A transverse oscillatory motion of the matrix is then provided by means of rotating cams 31 on which the matrix rests. The radial walls of the seal 8 may be curved to involute form. It is stated that as a further alternative, the oscillatory motion may be imparted to the rotating portion of the apparatus whether matrix or seals. According to the Provisional Specification the oscillatory movement may be controlled by hydraulic means.

Title: Improvements in inlet valves for toilet cisterns
IPC: E03D1/32
Filed: 1965-03-08
Abstract: 1,092,555. Fluid-pressure servomotor systems. W.H. GALLOGLY. March 8, 1965 [March 11, 1964], No. 9654/65. Heading G3P. [Also in Division F2] An inlet valve for a toilet cistern comprises a diaphragm 23 which co-operates with a seating 26 around an outlet which is connected by a passage 33 and annular space 34 to an outlet pipe 35. An inlet 11 is connected by a passage 29 to a space surrounding the valve seat 26 and also through a passage 30 to a chamber 25 at the upper side of the diaphragm. The chamber 25 is connected by a part 39 to a second chamber 38 having an outlet leading to passage 33 controlled by a ball valve 42. The ball 42 is actuated by a rod 43 and actuator 44 which is engaged by a lever 45, pivoted at 46, and carrying a float 47. In operation, when the toilet is flushed, a lever 48 raises the actuator 44 to open the ball valve 42 and thus connect chamber 25 to the outlet and the inlet pressure that actuates the diaphragm to allow flow to the cistern. When the liquid level in the cistern reaches the desired level, the float rises to allow the ball 42 to seat and thus cause closure of the diaphragm 23. If the water should not rise, due to a fault in the flushing valve, a reservoir 51 receives water through a part 50 from passage 33 and thus actuates the lever 45 to close the ball valve 42 after a predetermined time. A piece of elastic foam material 25' in the chamber 25 prevents shocks. This may be replaced by an air capsule or a spring-loaded member.

Filed: 1939-03-20
Abstract: 527,032. Cast chambered structures in situ. GODENIR, A., and WIMPEY & CO., Ltd., G. March 28, 1939, No. 9727. [Classes 20 (i) and 20 (ii)] Concrete air-raid shelters and like chambered structures are cast in situ in lined excavations by the use of sectional box-like or framed core boxes, which are preshaped and superposed as the casting proceeds and are subsequently removed for further use. The structure is of octagonal shape externally and of oval form internally and core members are so shaped as to form seats in the shelter and stairs leading to the shelter. The stairs are disposed at the ends of the shelter. The ground is first excavated and lined with slabs 1 at the sides ; a further converging portion is then removed to form a bottom and a gulley, and bent meshwork reinforcement is placed in the hollow. Flooring paper is then laid beneath the reinforcement and concrete is deposited working from the centre of the excavation towards the ends to form the base. Box cores B are then placed upon the concrete when it is partially set and the sides of the base are built up around these cores. Further open-ended cores G are then superposed to form shelves for the reception of the edges of floor slabs. Further box cores O and shaped cores R are then superposed and the concreting at the sides is continued to this level to form the seats p. Further sectional cores O, V and builtup frames 60, Figs. 7 and 8, are then superposed and the walls are continued to this height. Cores such as K. S. J, Fig. 8, are now positioned to form the steps in the approaches e and upper box cores O, Fig. 12, with tapered abutting faces are added to support an upper series of shaped cores Z<SP>2</SP> II over which the concrete is continued to constitute the vault of the shelter. The upper cores 20 in the passages e which form the halls d are continued above the roof level so that apertures r, Fig. 8, are formed, through which the core boxes and frames are finally removed. Doors c with hinges attached are positioned to open into the halls as shown in Fig. 5, and the concrete is cast around them to form frames, oil or paper being used to prevent the concrete from adhering. Rotatable air vents x may be fixed into apertures provided in the roof. The seats may be hollowed on their upper surfaces while the concrete is still moist and floor slabs are finally cast in the removable base frames G.
