Title: Expansion of tobacco
Inventor: BROWN IAN CAMPBELL
IPC: A24B15/32
Filed: 1984-05-30
Abstract: The method for expanding tobacco lamina comprises contacting the tobacco with an organic expansion agent, heating the thus contacted tobacco in a closed first vessel so that the temperature of the agent is above the boiling point of the agent at a lower release pressure, and suddenly venting the first vessel into a second vessel which is at said release pressure prior to the venting. By this means the fill volume of the tobacco is increased by at least 50%. <IMAGE>

Title: Optical fibre connector
Inventor: KETTERINGHAM TERENCE ALEXANDER
IPC: G02B6/38
Filed: 1984-06-06
Abstract: A multifibre connector comprises two coplanar blocks (1A, 1B) with a plurality of aligned, fibre-receiving grooves (3) formed in the top surfaces thereof and each having a cover member positioned on said faces to hold the fibres in the grooves. The two blocks are held together by a clip e.g. a circlip (2) running in a further groove (8) formed around the outer sides of the blocks. Alignment of the blocks may be improved by providing aligned cut-outs (20A, 20B, 21A, 21B) in the inner sides of each block which form a complete hole on abutment in which a round bearing (22) is held. The grooves may be pressed into the top face of each block whilst they are held together, each groove running across the top of both blocks. Curable resin is then put in each groove and a fibre (4A, 4B) is pushed into the respective groove in each block until it just sticks out from the inner side of the block within a blob of resin. The resin is cured and the end of the fibre ground to be flush with the end of the block. <IMAGE>

Title: Self priming centrifugal pump
Inventor: VOLLAND GEORG
IPC: F04D9/00
Filed: 1984-11-02
Abstract: The pump for pumping sewage (1) comprises a bladed impeller (3) which is rotated in a casing (2) having an axial inlet, an outlet (7), and a swirl chamber (6) oriented tangentially to the impeller (3). The swirl chamber (6) is arranged so that in the priming stage the liquid enters the chamber (6) where it creates a vortex (18) before re- entering and recirculating around the casing (2). On entering the swirl chamber (6) the liquid is accelerated outwards and then directed radially back inwards towards the impeller (3) by the shape of the chamber (6) so that it penetrates the drag stream (16) of the impeller (3) to strip air bubbles (19) from the surface of the impeller blade (5). The stripped air enters the vortex (18) to escape through the outlet (7). This creates suction at the inlet and continues until the pump is fully primed and liquid delivery commences. <IMAGE>

Title: RF amplifier unit
Inventor: COLE BERNARD VICTOR
IPC: H03F3/195
Filed: 1985-03-29
Abstract: An RF amplifier unit has an input connector (34) connected through an isolating resistor (R1) to the input of an amplifier (12) whose output is connected through a further isolating resistor (R1) to an output connector (16'). The input and output connectors (34, 16') are additionally connected through associated RF chokes (L) and controlled switches (33, 35) to the positive supply terminal "+" of the amplifier (12). Each isolating resistor (R1) is shunted by a further controlled switch (36, 37). In addition to RF signals at the connectors (34, 16'), one or other of the connectors may receive a supply for energising the amplifier (12) from an externally located source. The switches (33, 37) are rendered conducting when this supply is present at the output connector (16') whilst switches (35, 36) are rendered conducting when this supply is present at the input connector (34). In this way, the amplifier is energised from the supply applied at either input (34) or output (16') connector whilst the isolating resistor (R1) remote from the connector carrying the supply is short circuited. <IMAGE>

Title: "Apparatus for exercising horses"
Inventor: PILKINGTON JOHN
IPC: A01K15/00
Filed: 1989-12-06
Abstract: Apparatus for exercising horses comprises a pivot assembly 10 anchored to the ground and a structure 17 rotatable about the pivot assembly.
