Filed: 1969-07-09
Abstract: 1,232,322. Functional fluids; anti-corrosive coatings; heat transfer fluids. E. E. BALDWIN. 9 July, 1969, No. 34668/69. Headings C4A, C4X and C5F. Compositions of 5-95 wt per cent winterized whole grain rice oil, 1-75% white mineral oil, 0À1-50% sebacic acid diester and 0À1-10% oleic acid can be used as cutting oils for metal working, penetrating oils, lubricants for watches, guns, gear-boxes and electric motors, heatexchange mediums and non-drying or drying corrosion-inhibiting coatings for steel. Suitable diesters are dibenzyl sebacate, dibutyl sebacate, dimethyl sebacate, and dioctyl sebacate. A hard drying film can be produced on metals by adjusting the pH of the composition to 6À5- 2À0 with phosphoric acid, acetic acid, nitric acid, acetic anhydride or sulphamic acid. Greases can be made by mixing the compositions with silicas and/or methyl soaps.

Abstract: 1,250,666. Spray carburetters. GURTNER S.A. Nov. 13, 1968 [Dec. 22, 1967], No. 53766/ 68. Heading F1B. During cold running of an I. C. engine 13, Fig. 1, the float chamber 1 of a carburetter is communicated with an auxiliary chamber through a valve 9 to deliver extra fuel through a duct 5 to the carburetter induction duct 3. The valve 9 is controlled in accordance with the pressure differential across a diaphragm 10 dividing the auxiliary chamber into a compartment 4 subjected through the duct 5 to the suction within the induction duct 3, and a compartment 4' subjected through a valve 14 and a duct 12 to the positive pressure pulsations occurring within the engine crankcase. The valve 14 is progressively closed by a thermocouple 17 with increasing engine temperature, resulting in progressive closure of the valve 9. In an alternative embodiment, Fig. 2 (not shown), the diaphragmactuated valve is replaced by a valve controlled by an electrical solenoid (19) energized, via a bimetallic switch, to close the valve when the engine reaches a predetermined temperature. Moreover, the downstream end of the duct (5) includes a fuel reservoir (25) communicating with the induction duct through a vertical tube (7) having a series of vertically-spaced holes therein. Thus fuel continues to flow into the induction tube from the reservoir (25) after closure of the valve, until the reservoir (25) is empty.

Abstract: 1,252,978. Lasers. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Oct., 1969 [17 Oct., 1968], No. 48923/69. Heading H1C. In a chain of side pumped laser amplifier rods A 1 , A 2 , disposed on a common axis x-x<SP>1</SP>, inhomogeneity of the amplified output due to the greater population inversion in the radially outermost regions of the rods is compensated for by feeding the output from such regions of rod A 1  to the central regions of the adjacent rod A 2 . The output from the central region of rod A 1  is likewise fed to the outer regions of A 2 , the deflections being achieved by cones of half-angle α formed on the ends of the rods. To ensure that all the output of rod A 1  enters rod A 2 , the separation L of the rods and their radius R is chosen such that (n - 1)α=R/L, where n is the refractive index of the rods and α is small. To avoid fracturing the centre of rod A 2  by the large energy input from the outer regions of A 1 , an apertured diaphragm may be used to block part of the output from A 1 , Fig. 2 (not shown), or the distance L may be increased beyond the value found in the above equation, Fig. 3 (not shown). The latter alternative involves less energy loss. If the rods are of different radii, Fig. 4 (not shown), an afocal lens system is placed between them, and differing values of α are used. An expression for the position of the lens system and for L is given. To allow for non- parallel output from a rod, it is shown that α should not be less than 9 degrees and that the defect may be minimized by using a diaphragm or preferably by increasing the rod separation L substantially.

The check signal is used to detect lack of correspondence between the data and the address from which the data is requested. In the case of a simple parity check, for example, the address in which a data word 0010 is to be written may be 010. The overall parity bit is 1 and this is stored with the data word. When subsequently address 010 is read the data word 0010 and the parity bit 1 should be read out. By comparing this parity bit with one derived from both the address and the data word read out occurrence of error is detected. The use of other forms of error-checking code, e.g. Hamming code, is mentioned.

Abstract: 1330436 Photo-electric measuring apparatus INTEGRATED PHOTOMATRIX Ltd 24 July 1972 [26 July 1971] 34983/71 Heading G1A [Also in Division H3] Two or more light intensity values are compared (e.g. to find the largest or smallest) by producing simultaneous signals varying at a rate representing the magnitude of the respective values and feeding the signals to respective threshold devices, the first capacitor voltage to reach the threshold level causing the threshold device to prevent the other devices from producing an output. As shown, the selfcapacitances C l -C n  of photo-diodes are simultaneously charged by operating switches S l -S n  and then discharge at rates I l -I n  depending the incident light. The first capacitance to discharge to the threshold level of its associated bi-stable circuit A-N causes the circuit to be "set" and provide an output signal. The bi-stable circuit also acts via an OR gate to reclose the switches and recharge the capacitances. Accordingly, only the bi-stable circuit associated with the diode receiving the largest light value is operated. Subsequently a resetting pulse at X resets the bi-stable circuit whereupon the OR gate causes the switches to open and a new measuring cycle commences. If the bi-stable circuits are of  a type which resets when the input voltage rises, the circuit automatically recycles and the resetting circuit X may be omitted. The inverters R l -R n  may be field effect transistors and the circuit may be integrated.
