Patent GB-2099928-A (GB)
Title: Unloading containers
IPC: B65B69/00
Filed: 1982-05-24
Abstract: Unloading of tubular containers (23) is by way of a container-entrant plunger assembly (49) to express those contents via an inner tube (52) registering with a piercing of one end of the container. Peripheral severing of that end of the container allows a shape-rectifying size of plunger to be used and carry with it the severed container end. Fluid passages through the plunger head enable forced flow of fluid against or along inner walls of the container. Piercing and severing of the container end takes place at a separate station (30A) via a piercer (41) and cutter (42). All operations are shown from below and there are feed means to, from and between stations relative to a conveyor. <IMAGE>

Title: Portable power driver for increment corers
Inventor: BURBIDGE PETER RAYMOND
IPC: B27C3/08
Filed: 1983-04-05
Abstract: The Driver provides a self-contained, light and powerful method for driving auger type increment corers into a tree and then removing them. The device takes the place of the "Tee" handle normally used to drive the corer. The driver has a reduction gearbox and a double-ended shaft 6. The gearbox takes power from a standard chain-saw motor 1 and reduces the revolutions per minute, while increasing the torque available at the drive shaft. The drive shaft is fitted with square sockets 8,9 which accommodate the square shank of the increment corer. By fitting the corer into one socket to provide power in a clockwise direction the auger action of the corer forces the corer into the tree. By turning the driver around and using the counter-clockwise drive socket, the corer can be removed from the tree. <IMAGE>

Title: Liquid-level detecting device
Inventor: PRAS JEAN-CLAUDE
IPC: G01F23/24
Filed: 1983-09-12
Abstract: A device for measuring the level of a liquid in a tank comprises a plurality of resistive probes 10 disposed at successive levels on an insulating substrate 40, each probe having a temperature coefficient other than zero such that its resistance depends whether it is immersed to a greater or lesser extent in the liquid, and each probe being fed separately with electric current so that the voltage across it gives an indication of the extent to which it is immersed in the liquid. The voltage across the probes may be scanned and stored on energizing the probes, and then again after an interval. The ratio of voltages for any probe is indicative of the degree of immersion, and the corresponding value of liquid may be read from a read only memory and added to the readings for the other probes. <IMAGE>
