Abstract: 1,226,083. Automatic voltage and current control. INSTRUMENTATION SPECIALTIES CO. Jan.28, 1969 [oct. 29, 1968], No.4633/69. Heading G3R. An A.C. source is connected to input terminals 12, 13 and a regulated constant direct voltage or current is selectively developed at output terminals 14, 15, in accordance with the position of a switch 16. For constant voltage operation, negative feedback is obtained from resistor 27, amplifier 28 and transistor 30 to control thyristor 20. An offset voltage is applied to the amplifier 28 from potentiometer 32 and resistors 33, 34. For constant current operation, negative feedback is derived from resistor 25. If the output voltage or current drops below a desired value, the transistor 30 reacts to increase the rate of charge of capacitor 43. A signal is passed through transistor 36 and break-down diode 38 to turn on a transistor 37. A pulse transformer 44 then triggers the thyristor 20 at a phase angle which is advanced in proportion to the amount of deviation from the desired value. Diodes 45-47 and resistor 48 form a network to reset the capacitor 43 at the end of each half-cycle. A further regulator and low-pass filter stage comprises a transistor 24 whose average collectoremitter potential is set by a network comprising resistors 52-56 and transistors 57-59. A capacitor 61 forms a low-pass filter to prevent fluctuations due to ripple at the output of rectifier 18 from appearing at the terminals 14, 15. Resistor 54 is connected to amplifier 28 so that negative feedback signals pass to the further regulator stage.

A tong head comprises a case 6, 7, with a gear 76, driven by a transmission (4) the case including a wall for connecting it to the transmission (4), a bull gear 11 in the case, driven by gear 76, a tubular guide 21, 22, having a central opening, and bearings for rotatably supporting it on the bull gear, a single pair of diametrically opposed jaw guides 28, carried by the guide 21, 22, and extending radially therefrom, gripping jaws 40 reciprocable in the jaw guides into and out of the opening, and cam and follower means 44, 18, 19 in the channel and on the jaws for forcing the jaws into the opening upon relative rotation of the guide and the bull gear. The machine is as described in Specification 1,226,856.

Abstract: 1,239,494. Gas/liquid contact trays. SOC. POUR L'EQUIPEMENT DES INDUSTRIES CHIMIQUES SPEICHIM. 7 May, 1969 [9 May, 1968], No. 23390/69. Heading B1R. [Also in Division F2] A check valve for use in the tray 1 of a liquid/gas exchange column comprises a closure plate 2 movable relatively to a clip 3 which is plastically or elastically deformable to permit it to be passed through apertures 4, 5a, 5b in the plate and passage 9 in the tray 1. According to numerous modifications (Figs. 4-23 not shown) the clip can be of wire or sheet metal bent into a number of different shapes and it can be either movable or stationary relative to the tray.

Abstract: 1,239,752. Hull construction. J. G. OGLEBY. 29 Nov., 1968 [28 Sept., 1967], No. 44317/67. Headings B7A and B7S. A hull has an inner skin of glass fibre and resin 13 applied and formed in situ on an outer skin 12 of plywood or hardwood cladding. Preferably all fastenings which penetrate the hull are made before application of the skin 13 which is therefore unbroken. The deck cladding may have an external layer of glass-fibre/resins as may the outer skin of the hull.

Abstract: 1,251,465. Cot. DISPOSIT PRODUCTS Inc. Aug.3, 1970 [March 9, 1970], No.37395/70. Heading A4J. A foldable cot (shown in plan in the drawing) has end-walls 21 and sides each comprising two hinged elements 22, 22a. The pivots 29 are longer than the others 30 to enable the whole structure to fold flat. A hinged bottom rests on members 41 when the cot is open and folds up to lie in the same plane as the sides when the cot is collapsed. A hand bolt 37 retains the side elements when the cot is erected.

Abstract: 1,257,779. Automatic optimizing control. ROLLS-ROYCE Ltd. Dec.19, 1968 [Dec.21, 1967; Dec.29, 1967], Nos.58002/67 and 59028/67. Heading G3R. A digital computer perturbates a manufacturing or power plant in dependence on a pseudo-random binary sequence having two types of digit, one of which produces ramp perturbation signals of opposite slope alternately and the other of which maintains the perturbation signal constant, signals being developed in accordance with the effect of the perturbation on the plant output to drive the latter to a maximum or minimum. In Fig.1, a digital computer 28 derives ramp pulses from random binary sequences and applies them at B 1  and B 2  to oscillate a fuel valve 22 and a nozzle actuator 24 of a gas turbine 10. Signals corresponding to the resulting changes in engine thrust, produced at 26, are supplied to computer 28 which utilizes the binary sequences to separate the thrust variation signals into components corresponding to fuel and nozzle variations. The rates of change (slopes) of these components relative to the changes producing them are divided by their differentials (curvatures) to develop signals Z 1 , Z 2  which are applied to adjust valve 22 and actuator 24 in the senses necessary to increase thrust. These adjustments are repeated at intervals to attain and maintain optimum thrust.

Abstract: 1,258,990. Bite indicator. J. V. C. PUGH. 16 Dec., 1970 [16 Sept., 1969], No. 45468/69. Heading A1A. A bite indicator consists of a light rod 10, having a heavy ball 12 at one end, inside a slotted tube 16 which is mounted on a stake 20 which is driven into the ground. The line L is passed under the rod 10 and a counterweight 22 is adjusted so that rod 10 lies horizontal. When a bite occurs the line pulls the rod up then frees itself so that striking is unhindered.
