[Also in Divisions A5, E2 and F2]  A surgical clip (Figs. 1-11) or retractor (Figs. 12, 13) comprises a pair of telescoping members, plunger 12 and barrel 13, with respective jaws 10, 50 and 11, 51, a first pair of grips 25, 26, one on each member arranged so that a pinching action moves the jaws to an operative position, a second pair of grips, 16, 20, one on each of the members arranged so that a pinching action moves the jaws to an inoperative position, a pawl 21 on one of the second pair of grips on one member engaging ratchet teeth 15 on the other member to hold the jaws in their operative position, release of the pawl from the rachet being achieved by pinching the second pair of grips. As described, the plunger and barrel are non- circular to prevent relative rotation. The pawl is carried by one member on a spring arm 18 which is engaged by the grip on the other member to hold the two members together.

Abstract: 477,862. Implements for working land. LISTER & CO., Ltd., R. A., and ASHWORTH, P. B. Nov. 13, 1936, No. 31034. [Class 6 (i)] In a harrow having tines carried near the rear of the frame by members pivotally mounted near the front of the frame, the tines 30 are lifted periodically bv means of a driven screw 38 and cam 38a coacting with spring means 35 connected to the tine-carrying members 20, the spring 35 being stressed by rotation of the screw and then raised by the cam, thus raising the tines and also being drawn out of mesh with the screw so that it can return to its initial position. The harrow sections comprise a main frame 12, 25, 26 mounted on skids 23, 24. The tine member 20 is carried by longitudinals 28, 29 pivoted on a shaft in the tube 26. The tines 30 extend through holes 32 in the cross-bar 25 so that when the member 20 is raised against a stop 33 the tines are cleaned. The spring 35 which is U-shaped has one arm connected to the longitudinal 29 and the other carries a tappet 36 which coacts with the screw and cam which are rotated by prongs 39 engaging the ground. When the cam 38a raises the spring, the tappet 36 is released from the screw 38 and returns to its initial position, its movement being limited by a bar 40 and adjustable stop 42. A number of similar harrow sections may be connected to a draw-bar 18 by chains 17 and rows of chain links 22 may be drawn by the harrow as described in Specification 441,997. Skids 11 may be detachably secured to the frame members 12 by pins 13 and held either in the raised position as in Fig. 2 or the lowered position, Fig. 3, in which they hold the tines 30 clear of the ground.

Abstract: 1,107,086. Systems for heating buildings. HOW GROUP Ltd. 21 Oct., 1966 [22 July, 1965], No. 31139/65. Heading F4U. A number of individual heating circuits in a building are connected to a common supply and a pump in each circuit continuously circulates water within that circuit, hot water from the common supply being admitted as necessary to maintain a selected temperature in the circuit. As illustrated, a pump C circulates water in an individual circuit 4, 5, 6 containing radiators and/or hot water storage units. A thermostat D is provided to maintain a desired temperature in the line 6, and when additional hot water from a supply 1, 2 is required the thermostat acts through a controller G to close a valve A and open a valve B. A meter F records the time for which hot water is supplied, the rate of recording being dependent on the setting of the thermostat so that the meter reading gives a measure of the heat consumption of the individual circuit. In a modification, Fig. 2 (not shown), the valves A and B are replaced by a single three-way valve (J) and the rate of recording of the meter is dependent upon the temperature difference between lines 1 and 2. In a further modification, Fig. 3 (not shown), the three-way valve is used and the rate of meter recording is dependent upon the thermostat setting.

Abstract: 692,733. Pulse generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 11, 1951 [Dec. 22, 1950], No. 31226/50. Class 40 (vi). In a pulse generator of the type in which a capacitance C2 or delay line is periodically charged from a D.C. source X1, X2 and discharged through a load W, an auxiliary discharge path R is connected in shunt with the capacitance and is such that the voltage across the capacitance at the instant of discharge remains constant with changes in the recurrence frequency of the pulses. A reduction in recurrence frequency in the circuit shown causes the drain on the D.C. voltage source to decrease and therefore the D.C. voltage to increase but as the time MP (Fig. 2) between the completion of the charging of capacitor C2 and final discharge is greater the resistor R will discharge the capacitor more and the value at the instant of final discharge P will remain unchanged. The inductor L and the diode D2 cause the capacitor to charge to a voltage higher than that of the D.C. supply.

[Class 39 (i).] In an incandescent solidcathode rectifier, in which direct communication exists between each anode and the cathode, and in which the anodes are screened from each other, and partially screened from the cathode by an insulating tube or coating on each anode, the only path for the discharge consists of an opening in that side of each tube or coating turned towards the cathode. In one example, a rectifier, having a filling of inert gas, comprises graphite, iron, or steel a n o d e s 7, 8, Fig. 1, mounted within glass, quartz, porcelain, or magnesia tubes 9, 10 which are provided with side openings 13, 14. Iron or steel anodes are coated with chromium. The tubes are closed at their ends by covers 11, 12 under spring pressure. In a modification, (Fig. 2, not shown) the covers are dispensed with but the tubes are sufficiently long to prevent discharges therethrough. Each tube is constricted below its anode, which, when screwed on to its support, secures the tube in position against the pinch. In a further modification, groove-shaped anodes 7, S, Fig. 3, are coated with kaolin, with the exception of the bottom surfaces 18, 19 of the grooves.

In a method of gasshielded arc welding, two arcs within a single gas shield are used to fuse the same welding zone, one being struck between the workpiece 12 and a non- consumable electrode 8 and the other between the workpiece 12 and a consumable electrode 6 which is fed at a rate less than the burn-off rate. The two electrodes have the same current supply 11, and alternately support an arc. When a tungsten or a thoriated tungsten electrode is used the supply is alternating or direct current of straight polarity. Alternatively, a watercooled copper electrode can be used with alternating or direct current of reverse polarity. The shielding gas is argon alone or with additions such as carbon dioxide or 5 per cent oxygen. The electrode 6 and the workpiece 12 may be of steel. In a modification the electrodes have separate current supplies, each being of direct current of reverse polarity. The electrodes may be in tandem and either may lead.
