Filed: 1973-03-05
Abstract: 1383451 Dyeing polyolefins with vat dyes HOECHST AG 5 March 1973 [7 March 1972] 10535/73 Heading D1B Unmodified polyolefin fibres are dyed or printed in aqueous media with vat dyes, leuco esters of vat dyes or sulphur dyes under high temperature conditions i.e. at temperatures of at least 100C in the presence of a dispersing agent based on polyglycol-ethers or -esters which may be alkyl- or alkylaryl-polyglycol ethers or oxethylated fatty acid polyglycol esters. Padding and printing processes are followed by steaming at 100 to 135C for 10 to 40 mins a non-ionic protective colloid also being added to the pad liquors or print paste. An anionic protective colloid is used in exhaustion dyeing processes at 120 to 135C for 40 to 70 mins oxidation being subsequently effected. Unvatted dyes may also be applied when reoxidation is not required.

Pneumatic collectors; sweeping- machines ; taking up refuse for removal.-Relates to motor-driven roadsweeping machines of the kind in which a rotary brush delivers dirt to a conveyer leading to a receptacle, while the lighter particles of dust raised by the brush are removed by suction, and consists in providing the body of the vehicle with a compartment having an opening near the ground within which is mounted a rotary brush having a wiper for direct. ing the refuse on to an elevator leading into the dirt receptacle, suction means being provided for drawing the dust-laden air from the road surface, the dirt receptacle, and the space around the brush. Fig. 2 shows the rotary brush 8 mounted in the lower opening of a compartment formed by partitions 9, 10 within the body 1 of the vehicle. The front of the brush is surrounded by a hood 43 carrying a spring-controlled wiper 46, which retards the bristles of the brush and causes the refuse swept round the hood to discharge on to a conveyer band 27, which carries the refuse up an inclined plate 41 and into the bin 11.

Deacetylated chitin or this in admixture with polyvinyl alcohol or gelatin is used as colloid in colour transfer film units and processes, or together with silver precipitating nuclei is used in transfer image-receiving elements and units containing such elements for either black and white or colour transfer procedure. Composite units may include photosensitive as well as receiving elements, and include also a liquid processing composition in a rupturable container therefor. In Example 1 the deacetylated chitin is blended with aqueous acetic acid and silver acetate to form nuclei, coated on a hydrolysed cellulose acetate base and overcoated with an iodobromide emulsion, which latter is exposed, spread with the processing composition of Specification 684,591, and subsequently removed to leave a positive transfer image in the chitin layer. Examples 2 and 3 are similar but use gelatin and polyvinyl alcohol respectively along with the chitin, and provide the nuclei by deposition procedures as of Specification 863,516. Example 4 describes image production using a stripping layer over the receiving layer, and Examples 5, 6 colour image production using additive colour screens with the deacetylated chitin/ silver acetate blend of Example 1. Multicolour transfer materials and procedures using colour image forming components such as dye developers, colour couplers and coupling dyes also are indicated.

Patent GB-120876-A (GB)
Title: Electrical Control of Gun Movements.
IPC: F41A27/20
Filed: 1918-07-10
Abstract: 120,876. Soc. Anon. Italians. G. Ansaldo & Co. July 18, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Mountings.-Relates to electric elevating or training gear which can be operated by hand if the power fails, and consists in connecting the hand-wheel through an elastic clutch and a differential gear to a resistance regulating the action of the driving motor in such a way that, when the motor is working, no power is transmitted from the hand-wheel through the clutch, but as soon as the motor fails, a direct drive is obtained through the clutch. The invention is shown applied to the training gear. Fig. 1 shows an electric motor 5 mounted on the revolving gun pedestal 1 and driving a worm shaft 4 engaging a fixed worm wheel 3. The motor, which is shunt wound, receives current, through brushes 27 moving over contact rings 26, from a direct-current dynamo 23 driven at constant speed by a motor 24 connected with the mains 25. The dynamo 23 has double field coils 23, 23<2> for reversing the motor 5 according to the position of a switch arm 17 with respect to a rheostat 16 which regulates the action of the driving motor 5. This switch, which is of the hunting type, is actuated by a hand-wheel 8 through a yielding clutch and differential gear mounted in thei box 9 shown in detail in Fig. 2. The hand-wheel 8 is carried on a short shaft keyed to a sleeve-casing 15 having projections 15<1>, 15<2>, Fig. 3, which, according to the direction of rotation of the hand-wheel, act on one or the other of two disks 12, 13 freely mounted on the shaft 4 and connected by a torsion spring 14 which tends to return the hand-wheel to mid position. The disks 12, 13 carry projections 12<1>, 13<1> each working with lost motion between stops on disks 10, 11 keyed to the shaft 4. When the driving motor 5 is working, the yielding of one or the other of the disks 12, 13 causes differential movement of the wheels 19, 18 of the epicyclic gear 19, 18 20, and rotates the pinion 20 and switch arm 17 which are mounted on the same shaft. If the driving motor fails, the lost motion of the disks 12, 13 relatively to the disks 10, 11 is taken up, and the hand-wheel 8 positively drives the shaft 4, the pinion 20 and therefore the switch arm, remaining fixed. The switch arm may be operated directly by a handle x if desired.

A buffering-agent, e.g. a phosphate, acetate, phthalate or borate may be added to maintain the pH constant, and sulphur dioxide, hydrogen peroxide, chlorine dioxide, or activated carbon may be added to ensure a light colouration.  The pH may be reduced by means of hydrochloric, sulphuric, phosphoric, or mono-, di-, or trichloracetic acid. After the completion of the reaction, the product is neutralized with sodium carbonate, ammonia, potassium carbonate, or an alkali or alkaline earth hydroxide.  If desired, a product which has been treated to produce a diminution greater than the minimum may be mixed with an untreated solution.  U.S.A. Specification 2187122 is referred to.
