Title: Apparatus for applying lacquer or like protective coatings to articles
IPC: B05C3/09
Filed: 1953-03-24
Abstract: <PICT:0790297/III/1> <PICT:0790297/III/2> An apparatus for applying lacquer or like protective coatings to articles comprises a compressed air vessel containing the lacquer &c. in combination with a lacquer coating tank adapted to receive the article(s) to be coated and supported at a higher level than the said container, the base of the tank being in communication with the container and the tank having, or being supported on, a pyramidal or conical funnel in the apex of which is disposed the inlet for the lacquer or the like.  As shown, the tank 1, mounted on a stand 2, has a lid 14 with an inspection door 15, and its base 4, comprising a pyramidal control funnel which communicates with a graduated sight-glass 10, terminals in a T connection 5 surmounted by a domed lacquer deflector 9.  The lid 16 of the pressure container 3, which is secured by clamps 17 and carries a compressed air supply pipe 24, having a valve 30, a regulator 25 and a safety valve 26, also carries a filler cap 23, a pressure gauge 28, an air release cock 27, and is joined to the T connection 5 by a "flow" pipe 6 and a "return" flow pipe 7, both of which carry filters 18, 20 and valves 19 and 21 respectively.  The pipe 7 also carries an adjustable flow restrictor 22.  The article to be coated is placed in the tank 1 on supporting bars 8, the air inlet valve 30 is opened to pressurize the container 3, and the valve 19 is opened to admit lacquer to the tank at a rate controlled by the regulator 25. When a pre-set pointer 12 on the sight glass indicates that the article is immersed, the valves 19 and 30 are closed, the valve 21 and the air vent cock 27 are opened, and the lacquer is allowed to drain back to the container through the pre-set flow restrictor 22.  When the inside of a cylindrical vessel is to be coated, the vessel itself is clamped on top of a conical funnel, using an intermediate washer, and a cover having an inspector door is provided.  The lacquer is introduced into the vessel, and its level is raised, as before, until the whole of the surface to be coated is covered; dust &c. which floats to the top of the lacquer may be removed when the top level is reached.  Means for treating simultaneously a plurality of such vessels are described.  To prevent the compressed air from contaminating the lacquer an air bag or the like may be placed in the container 3 over the air inlet pipe, or activated carbon filters may be provided.

Title: Improvements in closures for orifices of containers
IPC: B65D41/34
Filed: 1940-05-07
Abstract: 538,536. Closures for containers. PHILLIPS, C. S., BRADBURY, T. H., and PHILLIPS TELESCOPIC TAPS, Ltd. May 7, 1940, No. 8228. [Class 125 (iii)] A replaceable screw cap 1 for a bottle, can or like has a non-replaceable element 8 accessible from the outside which engages a recess or projection when the cap is screwed home to close the bottle mouth so that rotation of the cap is prevented until the element 8 is broken or removed. The cap 1 has a depending flange 2 with depressions 3 so that it can be easily grasped. The lower edge of the flange has some inwardly directed portions 4 with their forward ends 4<SP>1</SP> depressed and their rear ends 4<SP>2</SP> bent up to limit the rotational movement of the cap. A lining piece 7 of resilient material is placed inside the cap. The bottle neck is shown with a number of projections 6 which are engaged by the parts 4 to screw the cap home, and which have one inclined face 6'. The locking member 8 lies on the upper surface of the cap as shown in Fig. 1 and a portion 8<SP>1</SP> passes through a hole 9 in the cap top and is bent to lie between the cap and its lining 7. Another portion 8<SP>3</SP> passes through the cap top and is bent round one of the projecting parts 4 and its end is located in a slot. The main portion of the locking element 8 rests on the cap and covers the first part of the word unsealed. An extension 8<SP>4</SP> rests in one of the recesses 3. When the cap is put on and turned, the portion 8<SP>3</SP> will ride up the inclined surface 6<SP>1</SP> of a projection 6, but reverse rotation to release the cap is prevented by the engagement of the portion 8<SP>3</SP> with the face 6<SP>2</SP> of the projection. Release can only be obtained by lifting the extension 8<SP>4</SP> to rupture the portion 8<SP>3</SP>.

Title: Improvements in or relating to slicing machines
IPC: B26D7/01
Filed: 1930-03-14
Abstract: 350,550. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H., Aden Road, Ponders End, Middlesex. March 14, 1930, No. 8241. [Class 28 (ii).] Relates to an abutment for supporting the substance adjacent to the knife, the abutment being automatically moved out of its operative position as the feed table, display tray or like member, approaches the knife. As shown in plan in Fig. 1, the abutment 13 is carried on a rod 15 slidably carried by the undertable. The rod 15 is pulled by a spring 16 which normally retains the abutment in its operative position. A two-armed lever 19, 20 pivoted on a bracket 21 on the under table, has, at one end, an upstanding member 22 which is engaged by a fitting 23 on the feed table. The other end 19 of the lever engages behind a lug 18 on the abutment member. As the feed table approaches the knife 10, the lever 19, 20 is swung and withdraws the abutment 13 from the path of the feed table. When the abutment is fully withdrawn, the member 22 engages in the space 24 behind the fitting 23 and is thus retained, allowing the feed table to complete its movement towards the knife without further affecting the abutment. When the feed table is retracted, the abutment automatically returns to its operative position. If desired, a lock may be provided to hold the abutment positively in its operative position, means being provided to release the lock immediately before members 22, 23 come into contact. In a modification, the abutment is held positively in its operative position by a spring- pressed locking-lever which engages a reduced portion of a rod carrying a spring which tends to slide the abutment out of its operative position. In this case, when the feed table is withdrawn, the abutment is forced in by hand and the locking- lever snaps into the reduced portion. The feed table, as it approaches the knife, abuts against the locking lever and releases the abutment. In a further modification, the abutment is associated with a sliding rod encircled by a tilting friction locking-ring. A spring tends to slide the abutment out of the path of the feed table, but is prevented by the locking ring until the ring is released by means actuated by the feed table as it approaches the knife. In this modification, the abutment is forced into the operative position against the spring pressure, and the locking-ring enables the abutment to be held in any desired position. The abutment in this modification, may be pivotally instead of slidably mounted. The abutments in all the modifications may be of any shape suited to the shape of the substance, and parts for actuating it may be arranged at the side of the machine remote from the operator.

Patent GB-1183692-A (GB)
Title: Improvements in Ferromagnetic Film Memory Elements.
IPC: G11C5/02
Filed: 1968-02-20
Abstract: 1,183,692. Magnetic storage devices. SOC. INDUSTRIELLE BULL-GENERAL ELECTRIC. 20 Feb., 1968 [8 March, 1967], No. 8292/68. Heading H3B. [Also in Division H1] Bridges of isotropic magnetic material provide closed, or nearly closed, external paths for magnetic flux in both the hard and easy directions of magnetization of a planar anisotropic thin magnetic film. Several embodiments are described, each using an anisotropic magnetic film which is deposited on a flat substrate comprising a non-magnetic sheet, e.g. copper, covered with a thin gold layer. Associated with the magnetic film are orthogonal word and digit conductors which, together with the isotropic magnetic bridges and interposed insulating layers, are formed by deposition and selective etching processes in well known manner. Fig.1 shows one arrangement in which a cruciform anisotropic film 11 has its external flux path in the easy direction provided by an isotropic bridge 18 which spans the word conductor 13. The external flux path in the hard direction is through an isotropic bridge 22 which spans the digit conductor 14, the air gap between the end portions of bridge 22 and the magnetic film being minimized by polepieces 20. The magnetic flux path through the latter bridge is completely closed in the arrangement shown in Fig. 3 by providing a bridge 30 displaced in the direction of the digit conductor 14 from conductor 13. An alternative and symmetrical arrangement is shown in Fig. 2A in which the bridge spanning the digit conductor 14 is divided into two parts 25, the parts being oppositely displaced from the word conductor 13 so as to engage the pole - pieces 23, 24. A symmetrical arrangement is also obtained in the Fig. 4A arrangement in which the word conductor 35 is divided into two parallel branches 35a, 35b so as to permit bridge 34 to have its end portions in direct contact with the anisotropic film, no polepieces being used in this case. A further embodiment, Fig. 5A, uses a single cruciform bridge 37, the four end portions of which contact the limbs of a cruciform magnetic film 36, the word and digit conductors 35, 38 both being divided into two parallel branches 35A, 35B, 38A, 38B, with a single branch located under each limb of the bridge 37. Storage elements as described may be used in a storage matrix and a single anisotropic magnetic film may be common to all the elements. The matrix may be made up of two integrated sub-assemblies in contact, one subassembly comprising anisotropic films, an insulated word conductor network, and bridges providing a closed flux path for one magnetization direction, while the other subassembly comprises the digit conductor network and the bridges for the other magnetization direction. Optionally, the latter bridges may be a continuous magnetic sheet.

Title: Improvements in or relating to mirrors
IPC: C23C14/24
Filed: 1938-03-17
Abstract: 577,669. Mirrors. TENNANT, W. J. (Pancro Mirrors, Inc.). March 17, 1938, No. 8301. [Class 97 (i)] [Also in Group H] A mirror strongly reflecting white light is produced by supporting a reflector body as of glass, crystal, or metal in a vacuum chamber, outgassing a strip of aluminium-magnesium alloy while preventing impure vapours therefrom from condensing on.the body, and then condensing pure vapours from the alloy upon the body. The reflector body may first be subjected in the chamber to the action of an electric discharge to clean its surface of residual gases which might impair the adhesion of the alloy deposit. The alloy may consist of 2-8 per cent of magnesium and 98-92 per cent of aluminium, 5 per cent of magnesium giving a particularly hard surface. Fig. 1 shows a vacuum chamber 11 in which is supported a mirror body B over one or more electric heating spirals D, each enclosing a strip of the alloy. The chamber is provided with a vacuum pipeline C and, above and below the body B, with electrodes I, J between which the cleaning discharge is passed. In this construction, the alloy is outgassed by heat before inserting it into the chamber, but a modified construction is described, adapted for coating two bodies simultaneously, in which removable shields in the form of flexible metal or cellulosic blinds 20, Fig. 5, are interposed between a central electrode 16 carrying the heating elements 18 and strips of alloy, and mirror bodies 14, one on each side of the electrode. The shields are removed during the passage of the cleaning discharge between the electrodes 15, 16, are let down during a preliminary heating to outgas the alloy and vaporize impurities therein, and are removed again during a final heating to vaporize the alloy and deposit it on the mirror bodies. Reference is made to an abstract of Canadian Specification 362,808 which describes a similar process, without the outgassing step.

Title: Improvements in or relating to clutch
IPC: F16D67/02
Filed: 1956-03-20
Abstract: 794,961. Hydraulic brakes. BORG-WARNER CORPORATION. March 20, 1956 [March 21, 1955], No. 8637/56. Class 103 (1). [Also in Group XXIV] A multidisc friction clutch 77 is disengaged against spring bias by hydraulic pressure (see Group XXIV) and simultaneously a brake pad 115 is pivoted to engage the outer cylindrical surface of the driven clutch drum 76, so that the driven parts are thereby brought to rest. The hydraulic pressure is provided by a gear pump 99, having a gear 100 rotating with the driving clutch shaft 11 and meshing a gear 101 in a stationary housing 103. The pump draws oil in through a hole 107 from a sump formed by a surrounding clutch housing 105. With the clutch engaged by its spring and the brake disengaged, the pumped oil flows through a passage 112 and an outlet hole 121 to return to the sump. To disengage the clutch and apply the brake, a solenoid (not shown) is energized to turn a shaft 128 carrying a cam 127 which moves a valve rod 116 downwardly against the bias of a spring 120 and closes the outlet hole 121. The pressure of the oil builds up, the pump 9a continuing to function, disengages the clutch and at the same time increases the oil pressure in passages 113, 114 leading to a piston on the back of the pivotal brake pad 115, which latter is accordingly applied to the clutch drum 76. A spring-biased ball relief valve 124 prevents build-up of excessive oil pressure by the pump 99.
