Title: Coating apparatus and method
IPC: B05D1/18
Filed: 1965-04-20
Abstract: 1,110,222. Coating apparatus. MINNESOTA MINING & MANUFACTURING CO. 20 April, 1965 [1 May, 1964], No. 16638/65. Heading D1L. Coating apparatus comprises a trough 21, a guiding roll 11 passing the web to be coated into the trough at 15 and out in an upward direction at 17, and a blade 25 located adjacent the point at which the web leaves the coating liquid and spaced from the web so that a meniscus forms between the blade and the web. One side of the trough 21 is open to the atmosphere as at 23, the other communicates with a reduced pressure chamber 31 by means of a slot 29 which extends the full width of the web to be coated. The reduced pressure in the chamber 31 is adjusted so that the coating liquid is drawn up at least to the height of the bottom of the blade 25 and preferably a little higher, thus creating a hydrostatic head indicated at 45. Coating liquid is fed into the trough 21 through a conduit 35 at the rate at which it is desired to be applied to the web, and is maintained at least at the level of the bottom of the roll 11, at this stage the maximum hydrostatic head is present. The web is passed through the coating liquid and a meniscus is formed between the web and the blade 25, a thin coating being left on the, web as it passes upwards from the meniscus. By virtue of the maximum hydrostatic head being present and thus a maximum downward force being exerted on the meniscus, less coating is applied to the web than intended, and since the rate at which liquid is taken by the web is less than the rate at which liquid is supplied, the level of liquid in the trough rises to say 43. The hydrostatic head and thus the downward force on the meniscus is reduced and consequently more coating liquid stays on the web. Once the point of equilibrium is reached, the apparatus is self-metering so the thickness of coating on the web is automatically adjusted to the rate of supply of liquid to the coating trough. In a further embodiment, Fig. 2 (not shown), a second coating is applied from a reservoir (57) by flowing it, under gravity, over the top surface of the blade (25). The apparatus is particularly applicable to the coating of films and paper with photographic emulsions &c.

Abstract: 628,519. Forging-machines; dies. COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE & D'HOMECOURT. June 25, 1947, No. 16786. Convention date, July 5, 1946. Addition to 622,938. [Class 83 (iv)] Making crank-shaf*ts.-The apparatus of the parent Specification is modified in that the upper central die is provided with a fluid lostmotion coupling to the press head so that in the first part of descent of the head only the lateral dies move. As the press head 13 begins to descend, the ramps engage and move inwardly the end dies 8 and 9 so that the work is upset or bulged between the end dies and the central dies 1 and 12 which during this phase, grip the work but remain stationary, a piston 2 carried by the head entering a cylinder in the upper part of the die. When the press head abuts the upper central die, these dies are moved downwardly, as the end dies are moved further inwardly so that the throw portion of the crank is displaced transversely and the sides of the throw are forged between the sides of the central dies and the inner ends of the end dies as shown in Fig. 5.

Title: Improvements in the balancing and lubrication of blades for rotary compressors and superchargers
IPC: F04C18/344
Filed: 1934-06-06
Abstract: 443,951. Rotary compressors. JAMESON, J. L., Elland, Hemingford Road, Cheam, Surrey. June 6, 1934, No. 16807. [Class 110 (ii)] The sliding vanes of a rotary compressor extend both sides of the axis, the centre of gravity of the blades being off-set with respect to the axis so that the same end of the blade is always operative. The blades 19 are arranged in pairs, the inoperative end of one blade strengthening the operative end of the other. The offsetting of the centres of gravity of the blades and the crossing of the pairs is effected by providing one pair of blades with necks offset with respect to the axis and the other pair with corresponding offset apertures. The vanes are lubricated by a central oil passage.

Title: Improvements in method in the preparation of progressive-burning smokeless powder
IPC: C06B21/00
Filed: 1938-06-08
Abstract: 528,035. Explosives. HERCULES POWDER CO. June 8, 1938, No. 17048. Convention date. July 6, 1937. [Class 9 (ii)] A progressive burning smokeless powder is prepared by coating smokeless powder grains with an admixture of a non-volatile non-explosive organic material, which is a non-solvent for the nitrocellulose but compatible therewith, and either a volatile or non-volatile solvent for said nitrocellulose. The expression " compatible therewith" is defined as meaning that the deterrent and the nitrocellulose of the smokeless powder are capable of existing together as a homogeneous system. The mixture may be rendered more fluid by (1) using a suitable emulsifying agent to form an aqueous emulsion thereof, (2) employing a volatile vehicle which is not a solvent for the smokeless powder grains or (3) forming an aqueous emulsion of such a volatile vehicle extended mixture. The smokeless powder grains when coated with the admixture are preferably treated with water at a point of incipient adherence of said grains to each other in order to prevent said adherence. Numerous examples of the various constituents of the mixture are given in the Specification together with a number of ways of preparing the smokeless powder. Specification 15865/93, [Class 9], is referred to.

Title: Improvements in methods of and apparatus for guiding fabrics
Inventor: HICKS ALFRED CHARLES
IPC: B65H23/038
Filed: 1961-05-10
Abstract: 943,106. Feeding webs. TURNER BROS. ASBESTOS CO. Ltd. Aug. 10, 1962 [May 10, 1961], No. 17084/61. Heading B6B. [Also in Division G3] The transverse position of each of several webs of material 1 which are finally united, e.g. to form conveyer belting, is controlled by causing a high frequency electric current to flow sequentially in conducting strips 54 in or on each web, and then detecting their position by electromagnetic means which produces signals to control correcting rolls 30, 31. The correcting rolls are mounted as shown in Fig. 7, one in fixed bearings below the web, the other above the web on a rocker arm 39<SP>4</SP> tiltable by an electromagnet 43<SP>4</SP> energized by the signals. There are two pairs of rolls for each web, each arranged to pull the web outwards from the centre when its electromagnet is energized. Fig. 15 shows an arrangement for one of five webs, which are united at calender rolls 12 in the complete machine, in which the current is induced in the conducting strip by coils 68, 69, the conductor circuit being completed by earthed capacitor plates 70, 82. In a preferred embodiment the current is induced by a capacitive circuit which includes adjustable plates, one for each belt, and a common metal run-out table. In another alternative, current is passed directly through the conductor by brushes. The detecting device comprises two pick-up coils 71, 72 arranged on either side of the conducting strip as shown or alternatively arranged above and below the strip in line with the desired position (Figs. 9 . . . 13, not shown). In either case, the coils are connected in series opposition and their resultant output is amplified and phase compared with a reference to produce a D.C. signal whose magnitude and polarity correspond to the size and direction of the positional error. The pick-up coils are situated close to the rolls 12 and are common to all the webs; a motor driven or a static distributer (Fig. 14, not shown) causes the sequential energization of the conducting strips and correspondingly switches the D.C. error signal to the appropriate electromagnet circuits. Each circuit includes a capacitor to store the signal while the other circuits are switched in turn so that correction is maintained throughout the switching cycle. The capacitors form the input to transistor amplifiers which energize the electromagnets, diodes being interposed to select the appropriate amplifier according to the polarity of the signal. The conducting strip 54 may comprise metal wire, a yarn of glass coated with metal, or graphite impregnated yarn woven or moulded in the fabric, preferably the selvedge, or it may be attached to the fabric by adhesive. Specification 870,734 is referred to.

Title: Improvements in or relating to electrical circuit for transmitting and receiving
IPC: G01S7/521
Filed: 1945-07-06
Abstract: 639,651. Acoustic directional apparatus. STEVENS, A. H. (Submarine Signal Co.). July 6, 1945, No. 17358. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 6, 1946.] [Class 118 (ii)] In a system for transmission and reception of compressional wave energy in which the same unit is used for both transmission and reception and in which high frequency electrical oscillations of the desired frequency are impressed across the unit as a transmitter by means of a transformer, the secondary of the transformer is connected to the unit in series with an independent inductance and capacity and an amplifying unit is shunted across the inductance for reception purposes, the impedance of the shunted inductance being substantially less than the impedance of the transmitting and receiving unit. The arrangement described, which may be employed for distance measurement by measuring the interval between the transmission of a signal and the reception thereof after reflections at an object the distance of which from the position of transmission it is required to determine or, for two-way communication between two similar but remotely located units, has for its object to prevent damage to the receiving amplifying unit when the system is in the transmitting condition. In the described embodiment as applied to distance measurement the output of a highfrequency generator 18 which is switched during transmission periods by cam-operated contacts 16, 17 is coupled to the transmitting and receiving unit 1, which may be a highfrequency oscillator of the magnetostriction or piezo-electric type, by means of the network L1, L2 and C1, L1 and C1, being adjusted to form a series resonant circuit at the operating frequency and L2 having a value which depends on the maximum voltage which may be impressed across the receiving amplifier 5 without causing damage thereto. During transmission periods the full output of the generator 18 is impressed across the series arrangement of the unit 1 and the inductance L2 but, because of the selected value of L2, only a part of this voltage (about 40 per cent) is impressed across the amplifier 5. The efficiency of the circuit is greatest when the impedance of L2 is somewhat below that of the unit 1. During reception periods contacts 16, 17 open and the entire received voltage across 1 is impressed across L2 since the impedance of the series resonant circuit L1, C1 is a minimum. The output of 5 is connected through the commutator ring 12 and brush 13 to an indicating device such as a neon discharge tube 11 which is carried on an indicating disc 10 driven by the continually rotating shaft 9.
