Abstract: 1,195,462. Coaling apparatus. GORKOVSKY AVTOMOBILNY ZAVOD. 23 Jan., 1968, No. 3414/68. Heading B2L. Apparatus for coating articles having a cylindrical shape comprises a tank, and at least two parallel rollers capable of supporting an article therebetween, the rollers 'being so arranged that when the tank contains liquid coating medium at a predetermined level, each of the rollers is partially immersed in said medium, so that rotation of the rollers said medium will be applied to the article. Three sectionalised parallel rollers I are mounted so as to be partially submerged in liquid contained in a tank 2 divided into five compartments by partitions 18. The rollers are driven by a motor 8 via a reduction gear box 9. Pistons 17 pass from a channel 5 on to a plate 6, the foremost piston lodging in a depression formed in plate 6 between the first and second rollers. Pistons also pass from a second channel to lodge in the depression in the corresponding plate between the second and third rollers. The piston rod of an air motor 3 carries rods 4 aligned with said depressions. Admission of air to alternate ends of motor 3 is controlled by a valve 13 actuated by a cam 12 driven via reduction gearing 11 from the axle 10 of one of the rollers 1. The arrangement is thereby such that the rods 4 reciprocate to push the pistons currently lodged in said depressions into the space between the rollers to become coated by contact therewith. The pistons are held in such contact by a shield 14 provided with nozzles 15 for the supply of liquid to the piston ring grooves. The pistons are de-greased in the first compartment, rinsed in the second, coated with tinning liquid in the third, drained an the fourth, and finally washed in the fifth compartment. The tank is suitably heated.

Heading D1N. Fibre feeding apparatus has a conveyer belt in a delivery channel that is arranged laterally of the inlets of downwardly inclined feed shafts and cross-conveying means in the form of nozzles arranged adjacent to each inlet in order to move fibres toward the inlets transversely to the movement of the belt. When supplying fibres from a scutcher to a battery of carding machines, the fibres are carried in an air current to a condenser drum from which they are deposited by a brush on to the belt 8 that conveys the fibres along the inlets of a series of vertical shafts 10, there being one shaft 10 for each carding machine 12. Blowing nozzles 9, say three per shaft, are arranged to blow fibres from the belt 8 into each shaft according to the level of fibres in the shaft, photoelectric cells 14 being provided to initiate signals relative to the level of fibres for control of a valve 16. When nozzles 9 are in operation pivoted screens 13 cut off the area of the belt 8 adjacent the shaft 10 to prevent escape of air along the belt. Specification 845,817 is referred to. Reference has been directed by the Comptroller to Specification 910,760.

Title: Improvements in or relating to fluid-pressure-operated braking apparatus
Inventor: BALLARD DONALD HENRY
IPC: B60T11/24
Filed: 1962-01-30
Abstract: 964,270. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Jan. 30, 1963 [Jan. 30, 1962], No. 3441/62. Heading F2F. In a fluid pressure operated braking system the kind incorporating separate systems for operating two different groups of brakes, a tandem master cylinder 1 embodies a pedal actuated main piston 2 and a floating auxiliary piston 4 normally spaced from the main piston 2 such that one cylinder space 1a is formed between two pistons and another cylinder space 1b is formed beyond the auxiliary piston, means being provided for transmitting hydraulic pressure created in one of the cylinder spaces (1b) to one set of brakes, i.e. the front brakes 7, and means being provided for transmitting hydraulic pressure created in the other cylinder space (1a) to actuate the control valve 9 of a fluid pressure servomotor 10 the output of which is transmitted by a separate hydraulic circuit to the other set of brakes, i.e. the rear brakes 15. Should a failure develop in the front brakes, displacement of the main piston 2 will first cause rearward displacement of the auxiliary piston 4 until it abuts the end of the cylinder. Pressure will thereafter build up in the space 1a between the two pistons to effect rear brake operation through the servomotor 10 operatively connected to a secondary master cylinder 13. Specification 835,970 is referred to.

Abstract: 902,297. Transferring designs. JOYNSON, C. Jan. 18, 1961 [Feb. 1, 1960], No. 3454/60. Class 100 (2). A process for transferring printed matter from an original base on which it is printed on to a new base comprises applying a coating of a liquid transparent synthetic resin adhesive over the surface of the print or of the new base, bringing the two surfaces together, allowing the adhesive to set, and removing the original base. The original base may be paper, removed by soaking, and pushing or rubbing, in the presence of boiled linseed oil. The new base may be paper, cloth, china, polyvinyl acetate or other material. The transferred print can be illuminated from behind if the new base is transparent or translucent. The adhesive may be a clear lacquer, comprising a combination of urea-formaldehyde glyptal and melamine resins, or alkyd resins, and is applied to the new base if the latter is non-porous, and to the print if the new base is porous.

Abstract: 607,434. Valve amplifying circuits. PHILCO RADIO & TELEVISION CORPORATION. Feb. 4, 1946, No. 3493. Convention date, Feb. 2, 1945. [Class 40 (vi)] In a cathode follower circuit means are provided to feedback a voltage from the anode to grid circuit to neutralize the feedback within the valve caused by the inter-electrode capacities which would otherwise cause the circuit to oscillate. In Fig. 3, the feedback is from a small resistor 12 in the anode circuit to the grid circuit by means of a condenser 13. Provision is also made in this circuit for feeding D.C. signals to the grid circuit via potential divider 10 and resistor 9. By altering the value of resistor 12, condenser 13 may be given such a value that the normal anode to grid capacity of the valve will give sufficient neutralization without the addition of any external capacity.

Title: Improved manufacture of magnesite cement
IPC: C04B9/06
Filed: 1923-02-06
Abstract: 214,369. Bakewell, B. Feb. 6, 1923. Plastic compositions containing oxychlorides. - A cement which does not corrode iron is made by adding ferrous chloride to magnesium oxide, the proportions being at least 30 parts of the crystalline chloride to 100 parts of magnesia. The chloride may be added as crystals or in solution. Fillers such as asbestos, sand, cork, may also be added, preferably those which do not absorb water to a great extent being used as excess of water destroys the non-corrosive property. For this reason the water added should not exceed 70 parts to 100 parts of magnesium oxide. Several examples are given in the Specification of which the following is typical : 100 parts of magnesium oxide, 45 parts of crystalline ferrous chloride, 15 parts of cork, and 62 parts of water. The solids are mixed dry, the water is gradually added, and the mass is mixed and used as rapidly as possible. Specification 1870/79, [Class 1, Acids, alkalies, &c.], is referred to. According to the Provisional Specification, the protochlorides of any metals forming two series of salts may be employed, and an example is given containing 15 parts of ferrous chloride to 100 parts of magnesium oxide.

Packeting by wrapping-up.- Relates to apparatus for wrapping small articles such as cigarettes in paper, tinfoil or both, and used to co-operate with cigarette-packing machines of the kind described in Specification 13957/15 or with machines in which bunches of cigarettes are intermittently fed. A strip 8, Fig. 3, of wrapping-material is fed by continuously-rotating feed-rollers 6, 7 through guides 27 into a shoot 28 and is severed below the guides 27 by a knife 31, Fig. 4, without the feed being interrupted. The knife is pivoted on a spindle 32 on an arm 34 on a continuously-rotating spindle 23. A stop 38 contacts with a portion 39 of the knife and retards it against the action of a spring (not shown) so that when the portion 39 arrives at position B and slips past the stop 38, it makes a rapid stroke forwards until arrested by a stop 40 and severs the paper 8 without affecting the continuous feed. The severed 'material is then occupying the shoot 28 and a slot 29 below the path of the cigarettes 1 on the conveyer 2. The cigarettes force the strip into a casing 30 with side folders 41, 42 so that an open ended packet as shown in Fig. 9 is produced. According to the Provisional Specification, the sides may be gummed and an electrically-warmed heating- chamber may co-operate with the side folders to dry the folds.
