Abstract: 1478763 Securing tail portion of web rolls CROWN ZELLERBACH CORP 23 April 1975 [3 June 1974] 16854/75 Heading B8R The free tail portion of a web roll is folded under and secured, by adhesive, to the underlying convolution of the roll. A fully wound roll 24, conveyed by an endless belt 14, is pushed sidewards on to support rollers 26, 28 by pusher rod 50, after having actuated a sensing arm 190 which starts rotation of said rollers. An air current from nozzles 54 causes the tail portion to be partially unwound from the rotating roll, the tail portion coming to rest on a platform 124, 126 and, in so doing, obscuring two photoelectric cells 70, 120. As the tail portion starts to be rewound on to the roll, photoelectric cell 70 is first exposed causing an applicator 32 to discharge spots of hot-metal adhesive 116 on to the underlying convolution. Cell 120 is exposed next, causing a plurality of laterally spaced blades on an L-shaped support 182 to pivot upwardly through apertures 76 in the platform thereby turning the tail portion end upon itself and holding it against the platform. As rewinding continues, the doubled over tail portion is pulled past the blades which form a fold. The folded portion then abuts the adhesive on the underlying convolution and is thereby secured to the roll. In an alternative embodiment, the adhesive is applied to the folded portion.

Abstract: 317,939. Siemens - - Schuckertwerke Akt.-Ges., and Weimers, W. June 12, 1928. Washing-machines with rotary receptacles.-In a machine wherein a receptacle 3, Fig. 1, is rotated within a casing 1, which may be swung on trunnions to an inclined position for washing and to the vertical position shown for centrifuging, and wherein the receptacle is raised to the dotted position shown for centrifuging, the raising of the driving-shaft 4 simultaneously connecting a higher speed gear train, the lever 7, by which the raising of the shaft 4 is effected, is arranged to prevent such raising from occurring simultaneously with the swinging of the casing from washing to centrifuging position, so that, if the motor has not been switched off, the receptacle continues to rotate at the slower washing speed although the casing has been swung to the centrifuging position. A lever 9 is pivoted at 8, Fig. 2, and is provided with a recess 9<a> which engages over the lever 7 when the pedal 7<a>, Fig. 1, is depressed, thereby locking the lever with its free end 7<b> in the raised position which corresponds to the raised or high-speed position of the driving-shaft 4. If the casing is swung from washing to centrifuging position while the lever 7 is so locked, the free end 7b projects into the path of the protruding lower end of the shaft 4 which consequently cannot be raised to connect the higher speed gear train until after the locking lever 9 has been released, the pedal 7a raised, the free end 7<b> engaged under the shaft 4 and the pedal again depressed. The locking lever 9 may be replaced by a cam plate 17, Fig. 6, having two operating pedals 15, 16. In this form the pedal portion 7<a> of the lever 7 is omitted, the lever being positively actuated and locked in its raised and lowered positions by the cam plate 17.

Title: Improvements in or relating to processes for increasing the resistance of metals to corrosion
IPC: C23C22/08
Filed: 1943-10-20
Abstract: In a process for the anti-corrosion treatment of metals by the formation of a phosphate coating thereon, the acid concentration of the treating bath is maintained between the limits of pH value of 1.8 and 2.5, preferably 1.9 and 2.2, for example substantially 2.0, no steps being taken to oxidise any ferrous ions which may be present in the bath or to control the content of dissolved iron in the solution within critical limits.  The treating bath may comprise a solution of an anti-corrosive composition consisting of iron sulphide or metallic iron in phosphoric acid.  Instead of iron sulphide, iron oxide or carbonate may be used, in which case there is added, either to the anti-corrosive composition or to the treating bath, a sulphide of one of the following viz: copper, zinc, manganese, nickel, cobalt, lithium, potassium, sodium, calcium, barium, strontium, and ammonium, together with hydrogen sulphide, if desired.  The hydrogen sulphide may be oxidised by the addition to the bath of ammonium iodate, chlorate or bromate together with an ammonium or a metal halide, for example, ammonium iodide or bromide.  The quantity of ammonium salts in the composition or in the treating bath is preferably kept below 10 per cent. based on the amount of iron.  The ammonium salts may include the carbonate, bicarbonate or primary, secondary or tertiary ortho-phosphate or a mixture of two or more such salts. The treating bath solution should contain no substantial quantity of alkali metal salts.  The articles to be treated may be immersed in a treating bath containing the phosphate solution diluted with tap water or distilled water to a pH concentration of 1.9 to 2.0, the bath being maintained at a temperature between 90 DEG  and 100 DEG C.

Abstract: 879,387. Fluid pressure braking systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. May 20, 1960 [May 21, 1959], No. 17309/59. Class 103 (1). Compressed fluid braking apparatus has a relay valve RV reproducing in a brake cylinder BC a pressure proportional to that produced by a distributer valve DV in dependence on the variations from a normal fully-charged value of brake pressure, and a two-sectioned auxiliary reservoir Al, A2, both sections being chargeable from a supply pipe SP charged at a pressure in excess of the normal brake pipe pressure, the section A1 being chargeable from brake pipe BP through the distributer valve DV, sections A1, A2 together being sufficient when charged to the normal supply pipe pressure to produce a maximum boosted braking while section A1 is sufficient when charged to normal brake pipe pressure to produce a maximum unboosted braking. The distributer valve DV pressurizes or vents a dummy brake cylinder D connected to relay valve RV, the ratio of brake cylinder pressure to dummy cylinder pressure being adjusted by a speed governor G which, at high vehicle speed, supplies dummy cylinder pressure to valve RV over a second path to set valve RV for boosted braking. Should pressure in pipe SP fail, the section A1 is charged from the brake pipe and has a capacity sufficient for low-speed braking, i.e. unboosted braking. In emergency applications, when the brake pipe is vented, a limiting valve L prevents an excessive pressure building up in dummy cylinder D.

Abstract: 613,902. Radio signalling. GENERAL ELECTRIC CO., Ltd., and GLADWIN, A. S. Jan. 21, 1946, No. 17581/47. Divided out of 613,854. [Classes 40 (v) and 40 (vi)] The invention relates to the means at radio repeater stations for converting the received frequency fc into a frequency fc+f1 for retransmission, and particularly to the type of which Fig. 2 is an example, in which fc is first mixed with a frequency fo to produce an intermediate frequency of fo -fc which after amplification at 3 is further mixed with a " shift " frequency f to produce a second intermediate frequency of fc -fo + f which is amplified at 6 and mixed with fo to produce the final frequency fc+f1 for retransmission. According to the invention, rejection of the unwanted products of the mixing is simplified by using an arrangement of which Fig. 4 is an example. Mixer 1 combines the signal fc with a frequency of fo+nf obtained from mixer 8 to produce an intermediate frequency of fo - fc+nf1, which after amplification is mixed with a frequency of mf (where (m - n)=1) to produce a second I.F. of (m-n)f1 - fo+fc. After further amplification, this frequency is mixed with fo to produce the final frequency fc+(m - n) f1. The frequencies mf, nf may be adjacent harmonics of a common oscillator. The application of the invention to a system handling two signals is described in Specification 613,854.
