Title: Gravimetric diluter
Inventor: CAMPBELL JEPTHA E
IPC: B65B3/04
Filed: 1982-02-04
Abstract: An apparatus (10) for making dilutions of a sample (11) with a diluent (36) to a predetermined dilution factor f by weight of the diluent. A scale (12) with TARE capability produces an output signal of the weight W of a sample within a container (20) less the weight of the container. A dilution factor control (24) is provided for setting the predetermined dilution factor f. Blocks (218 and 220) are provided for calculating and storing the value TW = W/f which is the total weight of the sample plus the weight of the diluent which is required to dilute the sample to the predetermined dilution factor f. A pump (42) is connected between a reservoir (38) of diluent and the container for the sample for pumping the amount of diluent into the container which is required to dilute the sample to the predetermined weight dilution factor f. The scale provides a continuous output of the weight W of the sample plus diluent in the container at any instant in time. Decision point (256) is provided for determining when TW - W = 0. In one embodiment, the flow of diluent to the container is stopped by closing a pair of valves (34 and 46) located between the pump and the container when TW - W = 0.

Title: Machine for operating progressively along a marginal portion of a workpiece of sheet material
Inventor: YARDLEY ROBERT
IPC: D05B35/00
Filed: 1983-10-25
Abstract: A cementing and folding machine. e.g. for operating on leather or fabric, having an "automatic" operating mode is provided with a facility for varying the "density" of snip, or other marginal operation at the discretion of the operator. To this end, a plurality of sensors is provided for monitoring the marginal portion, the condition of each of which is monitored at regular intervals in an operating cycle and stored in binary form. The bit value of all these "stores" is aggregated and the aggregate value is compared to a comparator value in order to determine whether or not a snip is to be effected in any one operating cycle (main shaft rotation). The comparator value is controlled by the operator, using a potentiometer the output voltage of which is converted to a digital value through an analogue- to-digital converter. It is envisaged that in addition to controlling the density of snip, the density of peat may also be controlled using the same principle. Furthermore, it is envisaged that the invention is also applicable to other margin treatment machines, e.g. stitching machines.

Title: Error correction in data transmission or processing
Inventor: CHAMBERS JOHN PHILIP
IPC: H03M13/03
Filed: 1984-04-17
Abstract: In a data transmission system, 14-bit samples (e.g. of an audio signal) of which one bit is a sign bit are grouped for transmission into groups of 32 samples. Error protection is applied to 7 bits only of each sample. The maximum value sample in each group is determined and securely transmitted, and error protection is applied to the sign bit, and to the bits corresponding to the six most significant bits in the maximum value sample, for all the samples in the block. Error protection is thus improved during quiet passages in the signal.

Title: Thermic lance and dual-stage combustion system
Inventor: PARTINGTON EDWARD COLIN
IPC: E21B7/14
Filed: 1984-12-18
Abstract: A thermic lance comprises a tube 11 of Al, Fe or Fe alloy and an inner tube and/or rods 12 of Al, Fe or Fe alloy, at least one tube or rod being of Al and at least one of Fe or Fe alloy, in a holder 13 including a valve 14 for controlling the supply of oxygen. The lance may be used for cutting or gouging metal, rock, brick etc. It may also be used for forming thermic weld material or for providing heat or weld metal directly to a weld site. A two-stage combustion system uses iron, aluminium and oxygen inputs with outputs of alumina, refined iron or steel and heat energy. In the first stage iron or steel is burnt, using free oxygen, to produce iron oxide particles and heat. The iron oxide is blown by the force of combustion to the second stage where it reacts with aluminium. The aluminium captures the bound oxygen from the iron oxide thus releasing the iron and producing further exothermic heat. Hence, three valuable and useful products are created: molten alumina, molten iron and heat. The starting materials may be scrap steel and used aluminium drinks cans. <IMAGE>
