Abstract: 1,018,372. Sighting instruments. CONTRAVES A.G. Feb. 6, 1964 [Feb. 22, 1963], No. 5025/64. Heading G1F. [Also in Division F3] A device for naval artillery practice comprises two sighting devices 1L, 1R rigidly joined together so that their lines of sight 10L, 10R respectively are set at a predetermined angle e.g. 60 degrees to each other. The device is mounted on a pedestal on the deck of a ship, and the device is carried by a horizontal platform stabilized by a gyroscope unit by way of a gimbal mounting so that an observer may make elevation and azimuthangle adjustments. Each sighting device comprises an eyepiece 13, an objective 14 and a camera system 11 using film which is developed in the camera. The observer sights one device on a partner-ship Fig. 5a; but the gun to be fired is trained at an azimuth angle of 60 degrees from this target. After the shot is fired a water spout will be visible in the other sighting device, Fig. 5b, and on seeing this the observer releases the camera shutters. The two films may be superimposed to indicate the hitting point of the shot relative to the partnership disregarding the 60 degrees angle. Alternatively the optical system of the device may be such as to combine the two images from the sighting devices on to one film. The invention is described as being used by two co-operating ships for target practice on each other, photos being taken for each shot fired from one ship by both ships so that the actual position of th hitting point of the shot in relation to the imaginary target can be computed.

Title: Thermionic timing means
IPC: G01S19/46
Filed: 1944-03-17
Abstract: 592,580. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. March 17, 1944, No. 5050. Convention date, Nov. 23, 1942. [Class 40 (v)] [Also in Group XXXVI] A burst of oscillations of constant amplitude is produced by generating a damped wave train and compensating a plurality of oscillations for the decay of the wave train. A pulse 32 from radar transmitter 10 increases the anode current in valve 22 to shock excite circuit 30 producing a damped wave train 33. The pulse 32 is also fed over condenser 45 and resistance 46 to the inner grid of valve 40, the pulse being distorted to the waveform 48 so as to vary the gain of the valve according to curve 50. The damped wave train 33 is applied to the outer grid of valve 40 and as the gain increases, the resulting output waveform 53 is rendered constant in amplitude until the gain of valve 40 ceases to increase. The oscillations are fed through a squaring circuit 60 and differentiating circuit 64 to a valve biassed beyond cut-off so that only negative spikes are formed and displayed on the cathode-ray tube 16. In a modification, Fig. 3 (not shown), the damped wave train 33 is fed to a rectifier shunted by a resistance to provide the variable bias to the valve 40. In a further modification, Fig. 4 (not shown), the valve 40 is replaced by a triode operating without initial bias. The damped wave train 33 causes the valve to pass grid current thereby producing a negative bias and decreasing the gain. The gain is small but rises at the commencement of the wave train as the wave train falls in amplitude. By arranging the amplitude of wave train 33 to be sufficiently large, the output from the triode is in the form of a square wave and may be applied to the cathode-ray tube directly.

Title: Improvements in or relating to the production of lubricant compositions
IPC: C07F9/141
Filed: 1941-04-23
Abstract: 552,732. Stabilized lubricating oils. ATLANTIC REFINING CO. April 23, 1941, No. 5264. Convention date, Feb. 20, 1940. [Class 91] [Also in Group IV] Lubricants and cutting oils of mineral oil, fatty oil, grease, wax &c. bases are stablized against oxidation by the addition thereto of a small amount of mixed ester of a phosphorous acid containing at least one and not more than two alkyl-aroxy-alkyl radicals ; the additive is also effective as an E.P. base. The oils treated particularly comprise lubricating oils of high V.I. obtained by solvent refining methods particularly when used with the harder but more corrodible bearing metals required in machinery subjected to extreme pressure conditions. To prepare the additive in general at least one mol of an ester is heated with 1 to 2.5 mols of an alkyl-aroxy-alkanol at a temperature of 200‹ to 500‹ F., reduced or increased pressure being used if necessary, the product being separated from the reaction mixture by usual methods. One or more of the alkanol groups are introduced into the ester. The proportion of the mixed ester added to the oil ranges from 0.05 to 2.0 per cent. An additional film strength agent may also be added, such as tricresyl phosphate. The starting esters may be aryl, alkylated aryl, alkyl, mixed alkyl-aryl, and hydro aromatic phosphites; the mono- and di-phosphites are included. Examples of a large number of specified phosphites comprise tri-phenyl phosphite, the tricresyl phosphites, the triethyl phenyl phosphites, and trimethyl phosphite. They may be esters of phosphorous acid, hypophosphorous, pyrophosphorous or thiophosphorous acids. The alkyl aroxy alkanols are of general formula RC n  H 2n-x  OR<SP>1</SP> OH, where " x " is at least 8 and the compounds specified comprise propyl phenoxymethanol, and octyl phenoxyethanol, the alkyl phenoxy and methanol or ethanol groups being replaceable by other alkyl, aroxy and alkanol groups respectively. The preparation of the reaction product of tricresyl phosphite and octyl phenoxyethanol is described in detail.

Abstract: 721,297. Metal sheet feeds; blank punching. ALUMINUM LABORATORIES, Ltd. March 25, 1953 [Feb. 28, 1952], No. 5312/52. Class 83 (4). Means for feeding sheet material past a press punch includes a carriage, to which the sheet is clamped, moved intermittently past the punch by a chain driven through gear means including a coupling adapted to be disconnected and connected to provide the intermittent movement and means actuated by the carriage to reverse its movement and to move the sheet holding member transversely to the direction of movement of the carriage so that a return row of blanks may be punched. A metal sheet 1, held by a pneumatic clamp 5 on a vertically movable part 4 of a carriage 2 movable along horizontal guideway 3 by a chain 6, is carried intermittently past a crank-operated punch adapted to punch out successive blanks in horizontal rows from the sheet. The chain 6 is intermittently driven by a sprocket on an output shaft 61 of a gear-box 10, an input shaft 32 of which is driven from a sprocket on the drive shaft of the punch crank. Drive from the shaft is taken from a bevel gear 39 thereon to one of two bevel gears 40, 41 on a shaft 42 and from a pinion 50 on the shaft 42 to a pinion 51 on a shaft 52 and thence through changeable gearing 55-59 to a shaft 54 and through clutch members 62, 67 to the output shaft 61. The clutch 62, 67 is intermittently allowed to disengage by an arm 70 on a shaft 74 rocked, by a cam 38 on the input shaft 32, against spring means 72 and a dashpot 81, which latter serves also to lubricate the bearings. The output shaft 61, which is capable of slight axial movement, is braked by the engagement of a brake member 102 thereon, under the action of springs 108, with a fixed brake member 101. The drive to the carriage 2 is automatically reversed, after a row of blanks has been punched from the sheet 1, by a stop 114, Fig. 2, on the carriage hitting a stop 112 on a rod 110 linked to a rod 90 carrying a cam follower 91 engaging a cam 37 on the shaft 32. The cam follower 91 is thus moved, still in engagement with the cam 37, from a position engaging one of two tappets 87, 88 to a position engaging the other. These tappets, through links 86, 85, rock a yoke 49 on a shaft 83 to move the shaft 42 axially so that a driving dog 47 thereon disengages a pin 45 on one bevel gear 40, 41, and engages a pin 45 on the other. The operation of the cam 37 is so timed that the pins are 180 degrees apart when the drive is disconnected, thus allowing the shaft 32 to rotate half a turn before the drive is reconnected so that the next row of holes is staggered relative. to the previous row. Rocking of the shaft 83 also rocks a lever 96 connected to a rod 111, Fig. 2, to move this rod in a direction opposite from that of the rod 110 and cause a stop 112 thereon to strike a lever 118 on the carriage to release the movable part 4 and allow it to descend a distance equal to one line spacing.
