Title: Vessel washing and drying system - projects jets of water and air downwards in succession at vessel rows in boxes
IPC: B08B9/28
Filed: 1975-05-23

Title: Heat pump for air conditioning - uses baffles to selectively circulate air through set of heat exchangers
IPC: F25B29/00
Filed: 1975-09-11
Abstract: A heat pump for room air conditioning to suit summer to winter conditions, has a refrigeration unit which circulates the refrigeration fluid permanently in the units in succession acting as heat exchangers through which fresh air and stale air is passed, with flaps controlling the flow, depending on the prevailing climatic conditions.

Title: Bullet for hunting rifle - has reduced section and weight and is held in tulip:shaped wad held closed by sliding ring
IPC: F42B7/10
Filed: 1976-03-03
Abstract: The bullet is particularly for a hunting firearm, being of greatly reduced section and slightly lighter than the standard one for the particular calibre. This gives higher muzzle velocity and much less deceleration during the flight to the target, so that there is a higher speed of impact. The section of the bullet can be roughly 50% of that of the gun barrel, it being accommodated in a wad whose section is equal to that of the barrel. The wad can be tulip-shaped, the petals being held in contact with the bullet by a sliding ring when travelling up the barrel. They open on leaving the barrel so as to release the bullet.
