Title: Melt viewing apparatus for vacuum furnace
Inventor: DOUGLAS JOSEPH
IPC: G02B23/24
Filed: 1982-01-27
Abstract: A sight tube 6 enables viewing of a melt through a vacuum furnace wall 1. The sight tube 6 has a lens 21 and a sight valve 42 inboard of the lens which is controlled by actuator 45 to move between a closed position in which the sight tube 6 is obturated and an open position which is maintained just long enough to allow registration of an instantaneous radiance valve by pyrometer 19. Whilst sight valve 42 is closed, a purging gas such as air accumulates in the portion of sight tube 6 outboard of valve 42, inflow of the gas being controlled by valve 44. When sight valve 42 is opened, a brief pulse of purging gas, insufficient to contaminate the melt, passes through valve 42 and down sight tube 6 thereby preventing contamination of the lens by furnace vapours, etc. <IMAGE>

Title: Shirred casings
IPC: A22C13/00
Filed: 1982-05-14
Abstract: The present invention provides a device comprising a tubular carrier 10 adapted for location on the tube or barrel of a packaging machine (not shown) from which a product to be packaged is ejected to automatically draw a portion of tubular packaging material to surround it said carrier carrying a supply of tubular packaging material 11, e.g. an elasticated netting, compressed axially thereof.   The carrier may be a plastics material or cardboard and means is provided for securing it to the machine barrel; for example, the carrier of plastics may have a bayonet joint type fixing while the cardboard carrier may be retained on the barrel by a clamp. The use of the device avoids the manual loading or shirring of the netting on to the tube or barrel of the machine. <IMAGE>

Title: Tube filter
Inventor: KIMBER GEOFFREY MICHAEL
IPC: B01D29/78
Filed: 1982-07-06
Abstract: A filter has one or more non-rigid filter tubes (3), preferably of braided wire, each attached at one end to a fixed tube plate (2, 6) and having an internal support tube or rod (9) attached thereto at the other end. The tube or rod (9) has a passage (10) for the removal of filtrate. Relative axial movement of the tube or rod (9) and the support element (2, 6), for example by hydraulic or pneumatic rams (16, 17), causes flexing of the filter tube, and removes accumulated filter cake. The filter is especially useful for aggressive environments, such as the high temperature filtration of coal extracts. <IMAGE>

Title: A c power control system
Inventor: MATTHEWS STEPHEN
IPC: G05F1/445
Filed: 1982-08-25
Abstract: The system includes push-pull load current controlling switches (24, 25) are each switched once in each duty cycle which consists of a number of supply cycles (23) so that A.C. is supplied to a load, e.g. incandescent lamps in an aircraft, for a complete number of supply cycles and a portion of the next cycle in each duty cycle.

Abstract: A method of cropping by the bed system, for example for cropping sugarbeet, wherein spaced rows of crops are grown with predetermined spacings therebetween, the crops being grown in groups of a predetermined number of rows with a standard spacing between the rows and each adjacent pair of groups being separated by a further space, or tram-line, and wherein virtually all traverse of the ground by implements up to a predetermined stage avoids any contact with, or compaction of, the soil between adjacent rows of any group, and including subsequently carrying out a plant treatment or harvesting step, utilising a tractor and a drawn or pushed implement for that step, wherein the tractor wheels run in said tram-lines but the implement is at least partially supported, e.g. by wheels or skids, running on the ground between pairs of rows of the group, such that the wheels or skids traverse relatively unimpacted ground, whilst the implement is connected to the tractor by a horizontal and forwardly extending pivotal connection which permits the implement to remain relatively horizontal on the bed whilst tilting movements of the tractor occur, as necessary, due to unevenness of the tram- lines.The implement and tractor are connected by a first part 102 connectable to the tractor lower links and a second part 100 connectable to the implement, the two parts being coupled in use by a single fore-and-aft pivot pin 140. Part 100 may be connected to the upper link 82 of the tractor and a locking pin 150 locks the parts together during transport. <IMAGE>
