Patent GB-824338-A (GB)
Title: Improvements in or relating to evaporators
Inventor: FRANKEL ADOLF
IPC: B01D3/06
Filed: 1956-08-07
Abstract: <PICT:0824338/III/1> A multi-stage flash-type evaporator comprises a series of heaters in which brine is heated and a series of flash chambers in which the heated brine is evaporated, at least one of the heaters being connected to a steam generator so as to receive steam as a heating medium, in which the majority of the flash chambers and the heaters associated with those flash chambers are constructed so as to produce a distillate stream of a purity which is below that required of make-up water while the remaining flash chambers and associated heaters are constructed so as to produce a smaller distillate stream of higher purity than the other stream, the steam generator being connected to the latter heaters so as to receive the higher purity stream as make-up water.  In a preferred embodiment the evaporator consists of a series of heaters 10 and a series of flash chambers 12.  Brine is passed through each heater in turn along the piping 14 under the pressure of a circulating pump 16, through the final heater 10a and then into the first of the flash chambers 12. Some of the heated brine evaporates in the flash chambers and the resultant vapour is passed into the flash chambers 10 with the exception of the final heater 10a through pipes 20 and collects as condensate.  Final heater 10a receives steam through a pipe 22 from a steam boiler 24.  Condensate from heater 10a is passed back to the boiler through a pipe 28 and the condensate from heater 10b passes to the boiler through pipe 26. Flash chamber 12a supplying the heater 10b is designed to be larger in cross-section than the other flash chambers so as to operate with lower vapour velocities and it is also equipped with efficient water separation equipment 30 which ensures that the distillate produced in heater 10b is of higher quality than the bulk of the distillate.

Title: Washing machine
IPC: D06F17/04
Filed: 1972-05-23
Abstract: 1429933 Washing machines HOOVER LTD 21 May 1973 [23 May 1972] 24227/72 Heading D1A [Also in Divisions F2 and F4] In a washing machine 10 having a chamber 11 in which articles are washed and a fan 20 for circulating drying air in the compartment, the fan is submerged and inoperative during the washing cycle and has a drive means which is operative when the liquid level drops below a predetermined level. As shown the drive means comprises a dog clutch member 25 slidable on the fan hub 21 in response to movement of a float 30 at the bottom of the chamber 11, and the fan drive shaft 14 has secured thereon a liquid circulating impeller 13, which supplies two rotatable spray assemblies, preferably through a valve which supplies them alternately, a drain pump impeller 18 and a cup-shaped clutch member 50. The impellers 13 and 18 are effective in the opposite senses of station of the shaft 14 which is belt-driven from a reversible electric motor. In operation on filling of the chamber the float 30 disengages the clutch members 25 and 55 so that on energising the motor only the circulating pump 13, the clutch member 50 and, through a pawl and ratchet mechanism 51/52, the clutch member 55 are driven. On completion of washing or rinsing the motor is reversed to drain the chamber and a pawl 40A engages ratchet teeth 41 and 57 to align the dogs 59 of the slidable clutch member 25 with slots in the member 55 so that at the float 30 falls the dogs may engage the slots. Finally the motor is reversed again and the fan is driven through the pawl and ratchet mechanism 51/52 and the dogs 59.
Patent GB-1117198-A (GB)
Title: A system and apparatus for producing and maintaining a reference pressure in a vessel
IPC: G01G7/02
Filed: 1966-05-31
Abstract: 1,117,198. Gas holders of variable capacity. KOBE STEEL Ltd. 31 May, 1966 [15 June, 1965], No. 24235/66. Heading F4X. The invention relates to a system in which a predetermined reference pressure from a source 6 is to be maintained in a chamber 5 particularly when a pressure sensing instrument such as a manometer 22 is to be tested or calibrated. One end of a piston 3 extends into the chamber 5 and a counterweight 15, corresponding to the reference pressure to be maintained, urges one end of a lever 13 into contact with the other end of the piston. Movement of the lever 13 is shown on an indicator 17. The chamber 5 is formed in a cylinder 1 and radial expansion of the cylinder and consequent leakage around the piston due to the high pressure in chamber 5 (e.g. 10,000 atmospheres), is inhibited by a counterpressure applied around the cylinder from a source 20. When the chamber 5 has been pressurized from the source 6 and the external surface of cylinder 20 is pressurized from source 20, valves 8 and 18 are closed isolating the system from the pressure sources. A check for leakage between piston 3 and cylinder 1 is then made as follows: The pressure in the system is slightly increased by turning a hand wheel 21 of a volume-varying device 9. The pressure increase due to movement of hand wheel 21 is shown on an indicator 11 and causes downward movement of piston 3 against the action of weight 15 and consequent movement of lever 13 which movement is transmitted to an indicator 17. In the event of no leakage a relationship will exist between the respective changes shown by the indicators 11, 17. If leakage is occurring as detected by a change in this relationship, increased pressure is applied to the outside of cylinder 1 from the source 20.

IPC: A22C25/00
Filed: 1964-06-11
Abstract: 1,070,025. Skinning, slicing and processing fish. FISKERIDIREKTORATETS KJEMISK-TEKNISKE FORSKNINGS-INSTITUTT. June 11, 1964 [June 12, 1963], No. 24327/64. Heading A2U. In a process and apparatus for skinning and slicing pieces of fish, such as gutted, boneless and headless herring fillets without tails the skin-sides of the pieces are brought into contact with a supporting surface having a temperature below -5‹C., so that the pieces become frost-bound to said surface. The pieces are then carried, on the moving supporting surface, to a knife, which severs and detaches slices of fish from the skin, which is then scraped from the surface. In the apparatus, Figs. 1 and 2, pieces of flesh 15 are transferred from a belt conveyer 14 on to the chilled surface 16 of a clockwise rotating, hollow drum 10. The skin makes contact with the surface 16, which is preferably maintained at a temperature below -20‹C. The drum carries the pieces under a resilient roller 17, e.g. made of foamed rubber or synthetic resin, which presses them firmly on to the drum surface 16 to which they become frozen. The drum then carries the pieces to a band-knife 18, which severs slices therefrom. The severed slices drop into a bin 19. The distance between the band-knife and the drum surface 16 may be adjusted, as by moving the band-knife in either of the directions indicated by the double arrow 27. The skin portions are removed from the surface 16, by a scraping knife 20, and deposited in a bin 21. The scraping knife may be heated. The hollow drum is mounted in bearings 11 and 12. A refrigerating fluid, e.g. chilled brine or ammonia, is fed into one end of the drum, through a conduit 22 in its axle. and passes out through an upright pipe 26 and a conduit 23, passing through the axle at the other end of the drum. Stuffing boxes 24 and 25 are provided. It is stated that the process and apparatus may be used for removing heads, tails, entrails and bones from fish.

Title: Data processing systems
IPC: G06F9/38
Filed: 1972-05-24
Abstract: 1355295 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 24 May 1972 [18 Aug 1971] 24346/72 Heading G4A A system performing overlapped execution of instructions is arranged to recognize normal conditions in the system and in response thereto store a system profile for use as a retry base should an abnormal condition be recognized subsequently. In the system described, a high speed store 11, to which all data accesses are made, supplies instructions and operands to an instruction unit 14 and execution unit 15. Unit 14 includes instruction buffer registers 16 which are normally kept filled and which supply instructions to a decode/issue section 17. The execution unit 15 may include separate arithmetic functional units 22-24 which each can buffer a plurality of operation controlling signals and operands relating to a sequence of pipelined instructions. The need to establish a checkpoint is signalled on occurrence of a number of specified normal system conditions, e.g. when the system cannot be restored to a previous checkpoint (I/O instruction, internal/external interrupt, request for channel control word); modification of control data not provided with back-up storage; storage back-up 33 full; predetermined number of instructions issued. The checkpoint signal inhibits the transfer of further instructions from unit 14 to unit 15 and when previously issued instructions have been executed (pipe-line drained), valid bits in back-up registers 31, 32 and pointer 34 are reset and the contents of an instruction counter 18 and a programme status word PSW are transferred to back-up registers 29, 30. Instruction processing is then resumed, every store opreation involving HSS causing pointer 34 to be incremented to address successive registers 33 to store the address and original data from the location of HSS involved. Similarly, store operations involving registers 26, 25 cause the corresponding original data to be transferred to the corresponding back-up register 31, 32 and the associated valid bit 35, 36 to be set. Abnormal conditions arising in the system require a recovery and retry operation to be carried out, e.g. on detection of a machine check condition. The recover signal 57 inhibits further instruction transfer from unit 14 to unit 15, and on completion of previously issued instructions the original contents of registers 26, 25 and HSS are restored from registers 31-33 and the instruction count and PSW are restored from registers 29, 30, pointer 34 being decremented for each restore operation into HSS.

Title: Improvements in sealed containers partly or wholly of glass and parts thereof, and methods of and apparatus for the manufacture thereof
IPC: B67B3/02
Filed: 1933-09-04
Abstract: 429,907. Glass manufacture. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Smith, R. D. ; 12, Woodlawn Avenue, Corning, New York, U.S.A.) Sept. 4, 1933, No. 24472. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 7, 1934]. [Class 56] [See also Groups XVII and XXII] A method of sealing containers which are constructed partly or wholly of glass consists in providing part of the glass with a fired-on coating of copper or silver, thickening the coating by depositing additional copper thereon by electrolysis, and then soldering a metal part to the copper layer. The glass is metallized by rubbing it while heated with a compound of copper, such as melted copper resinate, and subjecting the part so coated to a temperature of about 600‹ C. in the presence of air. After the glass parts have thus been treated, they are packed in charcoal in a metal box and passed through a leer in order to anneal the glass and to complete the reduction to metallic copper of the copper oxide in the deposited layer. The metallic coating is then thickened by electrolysis. A glass disc 10, which has had its edge coppered, can be tinned and sealed into a metal can top 14 by ordinary solder 15, a suitable flux being composed of 80 per cent zinc chloride and 20 per cent ammonium chloride. Preferably, the glass used is of the borosilicate type with low expansion and high thermal endurance, and the first metallic coating may consist of silver. In applying the coating of metal, the glass part may be mounted on a rotating shaft, after being preheated to about 500‹ C., and is further heated by means of a gas flame directed on the part to be coated. The copper resinate is stored in a receptacle, and a roller dipping into the receptacle applies the material to the rotating glass article. An alternative method of application consists in wiping a layer of molten alloy on the glass and scouring it on by rubbing with a swab of abrasive material, such as steel wool. The alloy may consist of aluminium, zinc, or cadmium, added to lead, tin, or bismuth, a suitable composition consisting of 85 per cent tin and 15 per cent zinc. A glass cover may be sealed to a glass baking dish by soldering a strip of metal foil across the rounded metallized edges of the dish and its cover. By cutting through the foil with a knife, or by providing a tearing-strip around its middle, the cover can be removed without damage. Similarly, a glass stopper can be sealed in the mouth of a bottle, or a sealing-cap of metal foil can be soldered to the mouth of a bottle, the rirn of which has been metallized.
