Patent GB-1091793-A (GB)
Title: Blending method and apparatus
Inventor: MOORE RALPH WILMOT
IPC: G05D11/13
Filed: 1964-11-11
Abstract: 1,091,793. Automatic mixture control. MOBILOIL CORPORATION. Nov.11, 1964 [Nov. 12 1963], No.45931/64. Heading G3R. A blended fuel product having a predetermined knock characteristic is formed by automatically controlling the amount of a component, added to influence its knock characteristic, in dependence on measurements of deviation of the knock characteristic and rate of flow. In Fig.2 a synchronous motor 64, normally supplied from mains 26, drives a cam 62 which periodically closes contacts 52a, b to energize a relay 36 and advance a motor 30 step by step. Motor 30 adjusts a weight (not shown) balancing a quantity of anti knock agent by means of a lever which regulates a valve controlling the rate of supply of the antiknock agent to a stream of petrol. A meter 60 responsive to the rate of flow of the petrol mechanically controls the follower of cam 62 so that the period for which contacts 52a, b is closed during each revolution, and hence the rate of supply of anti-knock agent, is dependent on the rate of flow of petrol. To ensure that the resultant octane rating is in fact maintained constant a test engine running on the mixture produces an electrical signal at 84 representative of error in the knock value. By means of a timer 96 this error signal is caused to adjust, through an amplifier-servomotor 100-82, the frequency of a source 76 which is substituted for the mains as a supply to synchronous motor 64 during the period that contacts 52a, b are closed so that the rate of supply of anti-knock agent is regulated to restore the octane rating to the desired value. Follow-up is provided by a servomotor 102 during the intervals between operation of timer 96.

Abstract: 1,197,207. Travelling-band filters. W. H. BLUMBER G. 12 Oct., 1967 [11 May, 1967], No. 46676/67. Heading B1D. Fluid to be filtered is pumped into a sealed chamber 10 divided into two compartments 28, 42 by a perforated plate 31 with which is juxtaposed a filter medium sheet 34; after filtration, a fluid pressure differential is created across the sheet 34 to lift it from plate 31; this facilitates changing the sheet. The apparatus comprises means (e.g. 71, 72) for advancing the filter sheet 34 over plate 31. As described, filter sheet 34 (which may be of paper fibres having carbon particles therebetween) is intermittently drawn off a roll 65 by driven rollers 71, 72: a doctor blade 75 removes filter residue. To filter, doors 48 are closed by rams 56 to seal the chamber and a pump (14) (Fig. 2, not shown) delivers the liquid to top compartment 28 through a top plate 27. The plate 31 has a number of parallel grooves 32 in it, at the bottom of which lie drainage holes 33, see also Figs. 5-7 (not shown), through which the liquid enters lower compartment 42 from which it is pumped via a conduit 43. The filtration is aided at a suitable stage by pressurising compartment 28 by means of a conduit (79), Figs. 2, 3 (not shown). After filtration, doors 48 are opened and compressed air is directed via conduit 43 into compartment 42 to levitate the filter sheet 34, whereupon roll 71 is driven. The inner walls and plate 31 of chamber 10 may be plastics-lined.

Title: Hardness Testing.
IPC: G01N3/48
Filed: 1966-10-26
Abstract: 1,163,144. Measuring surface hardness electrically. BELOIT EASTERN CORP. Oct. 26, 1966 [Dec. 13, 1965], No. 48000/66. Heading G1N. The hardness of a material, e.g. a roll of paper, is measured by moving a striker on to the surface of the material with a known kinetic energy and measuring the peak deceleration of the striker, as it hits the surface, which is a measure of the hardness of the surface. The striker 28, Figs. 1, 2, is first raised from a neutral position to a predetermined height above the surface of the material by the upward movement of a latch 62, engaging a latch keeper 64 on the striker. Movement of the latch is initiated and controlled via a steel band 21 by the pulling of a trigger 19, Fig. 1, by the operator. At the maximum height of the striker, the latch is knocked out of engagement with the keeper 64, Fig. 3 (not shown), to allow the striker to fall, under the action of a leaf spring 67, through a hole 79 in a shoe plate 77 on to the surface of the material. The striker is guided downwards by a parallel linkage 36, 37, 41. During the accelerated downward movement of the striker, a Piezo-electric sensor 32 in the striker generates a pulse whose peak voltage occurs at the moment of impact and is proportional to the impact force or deceleration and therefore to the hardness of the material. The pulse is fed to a circuit, Fig. 14 (not shown), where it is amplified and used to charge a capacitor to the peak voltage which is also transmitted to a voltmeter from which it can be read. The circuit is arranged so that the capacitor does not discharge its voltage until a switch (164, Fig. 14, not shown), or (97, Figs. 5-8, not shown), is closed at the beginning of the next cycle of measurement. Reference has been directed by the Comptroller to Specification 1, 027, 226.
