Patent DK-85592-A (DK)
Inventor: ARILDSEN CLAUS SLOTH
IPC: E06B3/54
Filed: 1992-06-29
Abstract: In the case of a scotching or supporting wedge (1) for filling in a space between two constructional parts, in which each wedge face is provided with transverse and transversally-oriented teeth (2, 5) having predominantly a serrated profile, the serrations of which point towards the thickest end (4) of the wedge, and in which each wedge face is provided throughout its length with guide mechanisms, a defective interlock has been established between two wedge faces in those areas of the faces at which the serrated teeth are prevented from engaging, the result being distorted scotching of the relevant constructional parts during erection. With a view to combatting such drawbacks it is proposed that the guide mechanisms be comprised of at least one slot (3) having a rectangular transverse profile, a depth smaller than or equal to 1/2A, where A is the height of the transverse serrated teeth (2, 5), and a width of X.A, where X > 0.

Title: Improvements in or relating to air-operated percussive tools
IPC: B25D9/08
Filed: 1956-01-04
Abstract: 799,442. Percussive tools. TURNER, S., and BAVERSTOCK, J. March 22, 1957 [Jan. 4, 1956], No. 363/56. Class 124. A pneumatic percussive tool, having a free piston in a cylinder and an air distributing valve with an actuating rod slidable lengthwise of the cylinder, the actuating rod and a bit holder being normally biased towards the work with the piston at the return end of the stroke and the bit holder clear of the actuating rod, is so arranged that pressure of the bit on the work moves the actuating rod and valve to admit air to the cylinder and cause the piston to strike a blow, the recoil of the cylinder restoring the valve and actuating rod to the normal position. As shown, the tool comprises a cylinder 10 having a piston 15, a head 14 at one end and a bit holder at the other. A valve 54 in the head admits air to a passage 37 leading to the piston cylinder in one position, and in another to a port 52 at the working end of the cylinder, a spring 60 biasing the valve to the latter position. A rod 55 attached to the valve 54 extends parallel with the cylinder and ends a short distance before a bit holder carrying, for example, type for marking billets. A rod 18 is slidably supported in a carrier screwed to the cylinder and is biased by a spring 17 towards the work. When the type is pressed against the billet, the rod 18 and the bit holder move against the spring 17 until the bit holder makes contact with and moves the rod 55 and valve 54 against the spring 60 to admit air to the cylinder and drive the piston forwards. The recoil of the cylinder is sufficient to move the valve back to its biased position and the cycle will be repeated so long as the type is pressed against the billet. The tool may be supported from an overhead beam and guided by handles 70.

Abstract: 550,907. Thermionic valve circuits. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Jan. 13, 1942, No. 526. [Class 40 (v)] A push-pull paraphase amplifier comprises a valve 2 to the control grid of which the signal to be amplified is applied, and the anode circuit of which includes one half 31 of a primary winding 3 and a resistance 6 of such magnitude as to feed to the grid of a second valve 7 a voltage equal to the input but of opposite phase. The cathodes of the valves are connected together and the output is taken from terminals 5. The anode supply is taken from a full wave rectifier 9 and is smoothed by a resistance 11 and condensers C1 and 12. Grid bias for the valves is taken from a resistance R1, in the common cathode lead and is fed to the grid of 7 through a resistance R2, and to the grid of 2 after further smoothing. A bridge is constituted by the elements C1, Rl, R2, C2 and 6, which is fed at one pair of opposite apexes by the supply lines and the other apexes are connected to the grid and cathode respectively of valve 7. In order to prevent hum from being fed to the grid of valve 7 the bridge is balanced by making Cl, R1 = C2, R2, the resistance 6 being balanced by the C1. The grid bias resistances may be in the ohmic resistance of the electrolytic condenser separate cathode leads.

Title: Improvements in colour television receivers
Inventor: JUSTICE JAMES WILLIAM HENRY
IPC: H04N9/24
Filed: 1962-01-05
Abstract: 985,108. Colour television receivers. SYLVANIA - THORN COLOUR TELEVISION LABORATORIES Ltd. April 4, 1963 [Jan. 5, 1962], No. 558/62. Heading H4F. In a beam-indexing colour television, cathoderay tube display system, indexing signals of angular frequency 3#/2 are obtained through tuned amplifier 12 from photo-multiplier 11 and applied to a frequency divider 15, whilst " runin " signals of angular frequency #/2 for resolving phase ambiguity in the divider operation are obtained through tuned amplifier 13, the circuit including gates 14 and 19 which are controlled by divider 15 such that gate 19 is open and gate 14 is closed during the scanning of the " run-in " stripes and their conditions are reversed once the divider starts operating. The characteristic feature of the invention is the use of a frequency multiplier 20 to derive a signal of angular frequency 3#/2 during the scanning of the " run-in " stripes. Furthermore, a multiplier 21 is used for deriving a signal of angular frequency # for starting divider 15 into operation in the correct phase. If the " run-in " strips are arranged to produce a signal of angular frequency #, multiplication by multiplier 21 is not necessary. The signal of angular frequency #/2 at the output of divider 15 is applied to remodulation circuit 17, which also receives the colour signals to be reproduced, and the resulting signal is combined in mixer 16 with the 3#/2 signal from gate 14 to obtain finally a colour modulated signal of frequency # for application to the tube gun 18. The Specification discusses the desirable occupancy of the " run-in " stripe (i.e. the ratio of stripe width to pitch) and in accordance with a further feature of the invention a value in the range 0À25 to 0À50 is chosen. Specification 895,772 is referred to.
Patent GB-309423-A (GB)
Title: Improvements in and relating to machines for the manufacture of hollow blown glass articles
IPC: C03B9/24
Filed: 1928-01-07
Abstract: 309,423. Hunt, S. Jan. 7, 1928. Blowing.-Relates to rotary machine of the suction-gathering type having combined blowing and suction heads which co-operate with ring moulds and through which the mouth-forming plugs enter the ring moulds. Each head is formed as a hollow casting provided with passages connected to sources of suction and of compressed air, and it is open at the top to allow a plug to pass through into the ring mould. The invention consists in providing the head with a rotary valve which, in one position, leaves a passage for the insertion and withdrawal of the plug and in another position closes the passage, cuts off the connection with the suction chamber, and allows the admission of blowing-air to the parison. Fig. 1 is a sectional side elevation and Fig. 2 a sectional front elevation showing the invention applied to a machine of the type described in Specification 165,800. The head comprises a casing 25 which is attached to a casting or framework 24 secured to the device for dipping the moulds when a gather is to be made. The casing 25 is formed with a passage 58, connected with the supply of compressed air, and with a top opening 56 through which plugs 54, for forming the mouth opening of the ware, can be moved. The interior of the casing is a cylindrical space in which a valve plug 55 rotates. The valve is mounted on trunnions 59 to one of which a pinion 61 is secured. The plugs 54, of which one or more may be used with each head, are formed on a plate 46 which, when it rests on the upper surface of the casting 25, forms an airtight joint therewith. The plate is attached to the underside of a cover-plate 40 forming part of a cradle 37 which slides in vertical guides and is connected to cranks 34 secured to the ends of a shaft 31. Rotation of the shaft thus causes vertical reciprocation of the plugs 54. The shaft is rotated by a bevel-wheel 21 driven in alternating directions by a rack 15 which is moved horizontally by a cam secured to the central column of the machine. A cam 71 is mounted on the shaft and is provided on one face with a roller 79 which can strike one end 80 of a lever 100 pivoted on the frame, the other end of the lever being pivoted to a rack rod 70 which meshes with the pinion 61 on the trunnion of the valve 55. The cam 71 is loosely mounted on the shaft 31 and is connected with it through a dog clutch and a coiled spring. Another spring on the pivot 81 of the lever 100 tends to draw the rod 70 upwards and thus keeps the valve 55 open. The cam 71 and associated mechanism (not shown) provides supplementary power to the cranks 34, as they approach their dead-centre position, to enable them to force the plugs hard home against the pressure required to make the plug shoulder seat itself on the ring mould.

Heading C1A. Alumina, balite mild, sodium carbonate and potassium carbonate are obtained from aluminosilicate rock by comminuting the rock and limestone and sintering and leaching the comminuted product with an alkaline aluminate solution at which stage belite mud is produced; the resulting solution is then desilicated (e.g. in an autoclave) the solution is then divided into two streams, the first stream is agitated and seeded precipitating Al(OH) 3  the second stream is subjected to secondary desilication (e.g. non-autoclave) and carbonation to produce Al(OH) 3 , Na 2 CO 3  and K 2 CO 3 . It is preferable to comminute the rock and limestone separately and to carry out the leaching in two stages: the first is countercurrent leaching in which is used an alkaline aluminate solution and a solution from the second leaching stage; the second leaching step is carried out in rod mills with wash water and the sinter is also comminuted further. Prior to sintering 2-3% of coal may be added to the mixture of rock and limestone. Where the starting material and limestone contain iron compounds, or where the alkaline aluminosilicate is low in alkali metals, an Na 2 CO 3 /K 2 CO 3  solution should be incorporated into the mix in an amount adequate for the formation of sodium (or potassium) aluminate and ferrite during the sintering step.

Abstract: 269,622. Campbell, C., and British Tabulating Machine Co., Ltd. Jan. 9,1926. Rotary distributors comprising rotary discs having trackways of alternate conducting and insulating material on which bear stationary brushes so that the circuits controlled are made and broken during the rotation of the disc, have an inserted body of refractorv material at the junction of the metal and insulating material to prevent damage of the latter by arcing. As shown in Fig. 1, brushes 22, 23 bear on the face of a bakelite disc 20 carrying a semi-circular metal segment 21. At the end of the segment where the curent is broken a plug 24 of glass or fused silica is inserted into the face of the disc, one side of the plug being rebated tc receive the end of the segment. Similarly, where the segment is let into the periphery of the disc a glass plug is inserted at the trailing end of the contact and another plug may be similarly inserted at its leading end. The plugs of refractory material are of such a width that the arc produced is extinguished before the brush reaches the surface of the insulating disc and no burning of the surface of the disc can therefore occur. In further modifications shown in Fig. 3 the arc may be cut off rapidly by the brush snapping off the inserted body of insulating material on to the surface of the disc either by arranging the inserted body to project above the surface of the disc as at 33 and 33a or by cutting away the surface of the disc behind the insertof refractory material 38 as at 37. An insert of dovetail formation is shown at 39.
