Title: A process for the preparation of non-corrosive or slightly corrosive aqueous solutions of capillary-active organic compounds
IPC: C11D1/12
Filed: 1948-06-03
Abstract: Non-corrosive or slightly corrosive aqueous solutions of capillary-active alkyl sulphuric acid ester salts or alkyl or alkylaryl sulphonates are prepared by adding not more than 10 per cent of the weight of the capillary-active substance and not more than 5 per cent of the weight of the solution of a water-soluble silicate, chromate or borate to the aqueous solution of the capillary-active material.  The silicate, chromate or borate may be formed in the solution if desired.  Alkali and ammonium silicates, chromates and borates and also metasilicates are suitable additives. The corrosive properties of the solution are effectively inhibited at temperatures as high as 100 DEG  C.  Examples are given of the corrosion inhibiting effect of adding (a) sodium silicate, chromate or borate to a solution of secondary sodium alkyl sulphates obtained by sulphation of alkenes having 10-18 carbon atoms in the molecule and neutralization of the sulphation product with alkali; and (b) sodium silicate to the product obtained by sulpho-chlorination of a de-aromatized gas oil fraction and saponification of the resulting sulpho - chloride with sodium hydroxide.  Specification 343,872 is referred to.ALSO:Non-corrosive or slightly corrosive aqueous solutions of capillary-active alkyl sulphuric acid ester salts or alkyl or aralkyl sulphonates are prepared by adding not more than 10 per cent of the weight of the capillary-active substance and not more than 5 per cent of the weight of the solution of a water-soluble silicate, chromate or borate.

Title: Improvements in or relating to machines for printing box boards and the like
IPC: B41F13/008
Filed: 1926-06-16
Abstract: 274,257. Berry, A. E. June 16, 1926. Throw-out arrangements.- In a machine for printing on boards, of the kind in which the boards are fed from the bottom of a pile by projections on a chain driven from the impression roller of the printing-couple, the feed-chain is driven by a slip-clutch which yields and disconnects the drive if the board being fed meets with an obstruction. In one form, the feed chain passes round a sprocket loose on the shaft h of the impression roller, and a second sprocket fast to a shaft which is driven by a second chain, the driving wheel i of which is loosely mounted on a boss g keyed to the shaft h and motion is normally transferred from the boss g to wheel i by means of a slip-clutch in the form of a spring-pressed ball k engaging a V of partly spherical notch g<1> in the boss g. The spring of the ball k is adjustably mounted in a bracket j connected to the wheel i. The arrangement is such that, after the obstruction is removed, the drive of the chain is taken up in such a manner as to retain correct printing register. In a modification, the second chain is omitted the ball k being mounted in a boss integral with the sprocket of the feed chain.

A blank is knitted starting from the cuffs 19 as flat fabric e.g. 2x2 rib Section A on both beds of the machine after which previously inactive needles are introduced to produce an e.g. 1 x 1 rib and knitting of sleeves 21, 22 is continued and widened Section B. If the main part is single jersey, all loops are transferred to one bed. In Section C, shaping is continued at the edges of the sleeves but needles are taken out of action along fashioning lines 24a-d which meet the sleeve edges at points 25 where the sleeves meet the body fabric 26 and edges 27, 28, 29 are cast on. Panels 26a, b, c are knitted, Section D and the needles are gradually brought back into operation along lines 32a to 32d, three yarn carriers being used. Part 26 is then knitted and finished by a waist band 35 and some waste courses. The blank is folded in half and seamed along the shoulders. The waistband is turned up and hemmed or linked and the front edges provided with buttons and button holes. The sleeves may be knitted in one piece and part cut out to separate them. In another arrangement, Fig. 5, the blank is knitted from the cuffs and the sleeves are widened and then shaped at the top edges 64, 65 while needles are successively held on edges 67, 69 until course 72 is reached when portions are cast on for the body being shaped along edges 79, 80 while the needles are gradually taken in again along lines 76, 77. Body 78 is then completed and the waist band knitted. The garment is made up by joining edges 64, 65 to edges 79, 80 and then joining the under arm seams. A jumper blank may be knitted to be joined down one side and with two sleeves attached Figs. 7 and 8 (not shown) the latter requiring two secondary beds movable longitudinally. A parallel machine may be provided with an arrangement for forming a loop of yarn 300, Fig. 9, drawn from the package which is used to prevent tightening of the stitches when the feeder runs beyond the edge of the fabric.

Filed: 1972-04-04
Abstract: 1425172 Compandors DOLBY LABORATORIES Inc 27 March 1973 [4 April 1972] 15485/72 Heading H4R In a circuit for modifying the dynamic range of a signal and having a linear main path whose signal component is boosted or bucked by the output of a flutter path, the flutter path contains a filter Fig. 3, having a first limited 24 output V A  taken from the junction of a resistive impedance R 1  and a reactance C 1 L 1  connected to the virtual earth input 15 of a current amplifier 14, and a second limited 25 output V B  taken from the amplifier output, e.g. across a second resistive impedance R 2 . The output V A  is determined solely by R 1  and C 1 L 1  which constitute a band-stop filter whose characteristics are complementary to those of the band-pass filter formed by R 1 , C 1 L 1  and amplifier 14. The circuit provides noise reduction of different bands of a colour video signal. Output V A  feeds a 1À6 mHz high pass filter C 2 R 3  to extract the 1À6-7À0 mHz luminance signal X, output V B  is the main 4À0-4À9 mHz colour component Y from which the 4À43 mHz subcarrier is removed by a trap 28, whilst 250 KHz-1À6 mHz luminance signals W are extracted by filters C 5 R 5  and C 6 R 6 . The threshold of the W channel limiter 26 is auto matically raised 27 with increasing input level whilst diodes 30 prevent forward-biasing of the limiter at high levels. In the noise reduction circuit (Fig. 5, not shown) the colour subcarrier band is extracted (41) from the main path, limited and added to the main path input during compression and subtracted from the output during expansion, and the subcarrier is supressed to prevent choking by subtracting a one or two-line delayed output signal from the main path component.

Convention dates, May 24, 1933 and March 5, 1934. [Class 38 (iv)] Systems depending on static transformers.- In a method of feeding an arc welding circuit with alternating current the potential difference has at the beginning of each alternation a peak of voltage which is sufficient for striking the arc, the remainder of the alternation corresponding to the voltage necessary for maintaining the arc. The three lines 1, 2, 3 of a threephase supply are connected to two single-phase transformers 4, 5. The secondaries of these transformers are connected in series with the load 8, 9, and the transformer 5 supplies voltage sufficient for maintaining the arc. The auxiliary transformer 4 has the core of its secondary winding 4b constructed of metal of high magnetic permeability whereby it is rapidly saturated and generates in the secondary winding a voltage of peaked form sufficient for striking the arc. The two voltages have a difference of phase of 120‹ so that the peak voltage is generated at the beginning of an alternation. The welding current is regulated by an arm 25 moving over the contacts 24 of a self-induction coil 23 In Fig. 6, the supply lines are connected to three single phase transformers, two of which are connected in V-formation to form a single transformer 5<1> for maintaining the arc. The voltage of the auxiliary transformer 4 is then either 90‹ or 180‹ different in phase from the voltage of transformer 51 in accordance with the connections of the latter.

Abstract: 1520177 Rotary positive displacement compressors BORG-WARNER CORP 15 April 1976 [16 April 1975 (3) 9 Feb 1976] 15766/76 Heading F1F In a sliding vane compressor (having non-radial vanes 34 as shown), the vane slots 30 communicate, between the suction 38 and delivery ports 42 with an arcuate port 68 in a side plate 18, the port 68 being intermittently connected to an oil sump 70 via a passage 66, interrupter means 64 and pipe 62. The interrupter means is a rotary disc 63 having apertures 65 therein and mounted on drive shaft 22. An arcuate recess 90 with a radial extension 92 in the end plate 18 prevents locking of the vanes in a retracted position by connecting the vane slots to the suction space. The disc 63 controls the extent of communication of the vane slots with oil at outlet pressure and thus when the compressor is stopped limits reverse movement of the rotor due to the oil in the vane slots. Oil trapped in the vane slots after an aperture 65 passes passage 66 will be forced past the vanes.
