Title: Improvements in or relating to vibratory barrel finishing machines
IPC: B24B31/06
Filed: 1963-05-27
Abstract: 1,093,484. Vibratory finishing. ALMCO SUPERSHEEN DIVISION OF GREAT BRITAIN Ltd. and C. J. A. KELLARD. May 25, 1964 [May 27, 1963], No. 21094/63. Heading B3D. A vibratory barrel finishing machine has means for introducing liquid into the barrel and outlet means arranged to discharge liquid from the barrel only when the level of liquid in the barrel reaches a predetermined height above the base of the barrel. An open top barrel 10 is supported by springs 11 on frames bolted to shock absorbing mountings bolted to the base 1. A vibrator 15 comprising an electric motor driving a rotary out of balance mass is secured to the underside of the bottom of the barrel. The barrel has at one end a gate 17 openable by a handle 18 for discharging finished parts and media at the end of a finishing cycle. At the other end of the barrel an elbow 21 of a stack pipe 20 is bolted to a boss 24 surrounding an opening 25 in the end wall 19. A perforated plate 28 prevents the passage of parts and media into the stack pipe. The stack pipe 20 is open at its upper end and has three discharge outlets 29. Compound in a tank 3 is pumped by a pump 35 through pipe 37, valve 38, T junction 34 and rotary valve coupling 31, supported by a member 30 secured to the stack pipe, to a sprinkler pipe 32 extending across the top of the barrel and having spray nozzles 33 spaced along its length. A pipe 41 connected to a selected one of the discharge outlets 29 returns the compound to the tank 3 through T junction 42, valve 43 and inlet 44; the other discharge outlets are closed by closure means. The desired level of compound in the barrel is thus maintained. At the end of a finishing cycle, the pump 35 is stopped, valves 38, 43 are closed and valves 39, 46 associated with the T-junctions 34, 42 respectively are opened. Water from supply pipe 40 than passes to sprinkler pipe 32 and into the barrel, and is discharged to drain, thus flushing the barrel and its contents before emptying the barrel.

Title: Improvements in and connected with railway block signalling instruments
IPC: B61L23/12
Filed: 1922-08-09
Abstract: 201,051. Dibbin, H. A. Aug. 9, 1922. Signalling instruments.-A block-signalling- instrument or switch for supplying current to and cutting current off from electric locks on signal levers in the rear cabin comprises a switch member controlling the circuit to the locks, and a magnet in the circuit of a track switch controlling the return of the instrument-switch to the normal position. A switch 6, bridges two springs 7 when in its operated position, thus completing a circuit to the rear cabin and releasing the lock on a master lever. A slide is then raised manually permitting a spring-bolt 10 to fly out and prevent return of the switch 6. A blade 14 falls over the end of the bolt 10, preventing its return until the blade is lifted by an armature 17 of an electromagnet 18, the circuit of which is completed by a track-switch as the train passes through the section. A detent 19 then holds the blade clear of the bolt, the detent being released by a cam 21 on the slide when the latter is raised or lowered. The return of the bolt 10, frees the switch 6 which returns to the normal position under the action of a spring 26, the consequent cessation of current operating the locks at the rear cabin to permit the master lever to be returned to the normal position. The switch 6 may be connected to an indicator showing its position. Specification 181,186 is referred to.

Title: Improvements relating to a method of heat transfer
Inventor: HORROCKS STANLEY
IPC: F28F13/02
Filed: 1968-05-08
Abstract: 1,224,056. Evaporators; desalination of sea water. S. HORROCKS. 5 May, 1969 [8 May, 1968], No. 21691/68. Heading B1B. [Also in Division F4] A scale-forming liquid solution or slurry in a space 13, Fig. 2, bounded by a fluid permeable heat transfer wall 11, is heated through the wall by means of a vapour 14 flowing in a space 12, the vapour condensate forming on the wall surface a layer 16 which is positively conveyed (e.g. by fluid pressure differential) through the wall as indicated by arrows 21) to the other surface thereof where the migrated fluid (denoted by arrows 19) forms a turbulent layer inhibiting the formation of scale on that surface. The drawings show the invention applied to the evaporation of sea water by steam. A layer 16 of condensate from the steam forms on the wall and the pressure differential across the wall causes migration of the condensate in the direction 21. In Fig. 3, the porous wall comprises tubes 27, 28. A space 29 external to the tubes and bounded by tube sheets 24, 26 is occupied by the scale-forming liquid. This liquid enters at 34 and concentrated liquid is discharged at 36, 39 and 41 are venting means and 42, 43 and 44 are means in the vapour circuit to remove entrained droplets. The liquid in the space 29 is first heated by means not shown, to its boiling point so that vapour is released at the free surface 31. This vapour, together with any recycled vapour emitted from tube 27 (as denoted by the arrows in Fig. 3) then enters a thermocompression device (shown as a fan 32) and the heat of compression raises the temperature of the vapour discharging from the device 32 to porous tube 28 in which therefore occurs some condensation and hence heat transfer with the liquid in space 29. This condensate collects in a pool 46 discharging at 38. The vapour then flows through tube 27 where further condensation occurs, this condensate being collected at 47 at discharged at 37. The remaining vapour discharges from tube 27 and after passing through detrainment means 42 is again mixed with vapour from the surface 31 entering the fan 32. In a modification, the vapour released from the surface 31 may be used for some other purpose or condensed, the fan 32 being supplied with vapour from an external source. The porous wall may comprise sintered metal particles and spirally welded tubes may be formed from long sheets of the porous material.

Abstract: 992,055. Mechanical garages; endless conveyers. O. A. GIBBONS. March 16, 1962, No. 21706/60. Headings B8A and B8E. A mechanical garage comprises a plurality of separate units 13 arranged as shown in Fig. 2 with their exits and entrances staggered. Each unit is an endless chain conveyer in which a pair of parallel guided chains 3, Fig. 1, support between them a succession of vehicle carriers 17 running on guides 4. Associated with each unit is a control device comprising a pointer 57, Fig. 4, movable over a dial bearing indications 59 corresponding to the carriers 17. The pointer is fast with a shaft 69 which is itself a friction fit in a hub 68 attached to the dial 56. Rotation of the pointer thus closes a switch 75 and one of the switches 78, 80. In a control circuit (Fig. 6, not shown) switch 75 prepares a motor circuit and switches 78, 80 respectively control clockwise and anticlockwise rotation of the motor, it being arranged that the motor will turn in the direction necessary to bring the required carrier to the exit or entrance by the shortest route. Final energization of the motor is by way of push button switch 60, Fig. 4, and the energized motor drives the conveyer unit directly and the dial 56 by way of the gearing 61 to 67. The dial carries the pointer and shaft with it until the switches 75, 78, 80 become broken at the illustrated position.
