Title: Improvements in or relating to the impregnation of metallic objects with a filling or sealing composition
IPC: C23F11/06
Filed: 1935-02-01
Abstract: 453,226. Anodic treatment of metals. SUTTON, H., and LE BROCQ, L. F., Royal Aircraft Establishment, South Farnborough, Hampshire. Feb. 1, 1935, No. 3236. [Class 41] [See also Group VIII] Metallic objects such as castings, e.g. of aluminium, magnesium or their alloys are rendered impervious by anodic treatment in a composition containing a soluble silicate and a soluble or slightly soluble chromate. Exemplary compositions are an aqueous solution prepared from sodium silicate and sodium or potassium dichromate or chromic acid, sufficient dichromate being preferably added to cause incipient precipitation of silica, and a suspension of zinc chromate in sodium silicate solution. In a modification castings are first treated with a solution of sodium silicate and then electrolytically with a solution or suspension of a chromate, for example, a solution of zinc chromate in chromic acid. After the impregnation the castings are rinsed, dried, and preferably stoved at a temperature below 125‹ C. The impregnation may be repeated.

Title: Safety tap for the control of a single supply of gas to two burners
IPC: F16K35/04
Filed: 1970-01-23
Abstract: 1280371 Valves SABAF-SALERI BATTISTA & FIGU SpA 23 Jan 1970 [18 Feb 1969] 3378/70 Heading F2V A tap for controlling a single supply of gas to two burners, comprises a two-part casing 1, 3, a valve member 2, and an operator stem 13 which is capable of both axial and rotary displacement, the arrangement being such that only one burner is supplied with gas at any one time and before the other burner can be connected to the supply, the valve member must pass through a state corresponding to the fully closed condition of the valve. The stem is urged outwardly relative to the valve member by a spring 22, and includes an L- shaped projection 15, 17, part 15 of the projection co-operating with a slot 16 in the valve member whilst part 17 of the projection is, in the closed state of this valve, acted upon by a downwardly depending projection 23 formed integrally with a ring 18 urged towards the stem by a spring 19. The ring is formed with two diametrically opposed and outwardly extending lugs, (21, Fig. 4, not shown), of which one is located above projection 23. When assembled, the ring lugs (21) are disposed within two recesses 8, 8<SP>1</SP> formed in the casing part 3, and part 17 of the stem projection 15, 17 is located within a recess 10 in the base 6 of the casing part 3, such disposition of the stem projection corresponding to the closed state of the valve. Operation of the valve for supplying gas to one of the burners is effected by displacing the stem 13 axially inwardly such that projection part 17 clears the recess 10 and then rotating the stem until part 17 engages with a corresponding one of two shoulders 12, 12<SP>1</SP> of a lug 11 formed in the casing base. Subsequent to such rotating of the stem, the ring projection overlies recess 10 and is flush with the base surface 6 over which projection 17 moves. Consequently, when the stem is rotated in the opposite direction, the projection, upon reaching the vicinity of rceess 10, engages the ring projection 23 and displaces the latter sideways in opposition to spring 19 which is anchored at 20 and 20<SP>1</SP> to the ring and the valve casing respectively, the degree of displacement of the projection 23 being limited by engagement between ring lugs (21) and the walls of recesses 8. With the ring projection so displaced, the stem projection 17 is urged to enter recess 10 subsequent to which the ring projection 23 returns to a position overlying the stem projection. Accordingly before the stem can be further rotated to supply gas to the other burner it must first be axially displaced as before.

Abstract: 935,529. Testing radio navigation receivers. COMMUNICATIONS (AIR) Ltd. Feb. 1, 1960 [Jan. 30, 1959], No. 3385/59. Class 40 (7). The radio receiving equipment on an aircraft for receiving Localizer, Glide-path, Marker Beacon and VOR radio signals is tested when the aircraft is on the ground by transmitting such radio signals sequentially from a test unit spaced from the aircraft, the type of signal being transmitted being indicated to the person in the aircraft testing the receiving equipment by means of a monogrammic indicator pane] 26 at the test unit. The test signals may be radiated from respective aerials 5, 6, 7 on the test unit or they may be coupled to the aircraft equipment by coaxial cables. The sequential transmission is controlled automatically by a timing circuit 25 but manual control means are also provided for overriding the automatic sequence when desired, the change from one test signal to the next being then initiated manually by the test operator. As shown, the timing circuit 25 controls: (1) a switch 11 which selects the crystal controlling the required radio frequency; (2) a function switch 15 which selects the required modulation signals for the glide-path, VOR and Localizer transmitters 1, 2, 3; (3) a marker switch 22 which controls the keyed tone signals for the Marker Beacon transmitter 4 ; and (4) the indicator panel 26. The duration of each test signal is in accordance with the prescribed time for carrying out the tests on the corresponding receiver equipment. The 30 c/s. modulation for the VOR transmitter is derived from an oscillator 13 and six bearings may be simulated by adjusting a phase-selector 16. The 90 c/s. and 150 c/s. modulation signals for the Glide-path and Localizer transmitters are derived from the oscillator 13 by a clipper 17 and harmonic amplifier 18, 19 and their relative amplitude is controlled by a mixer 20 and indicated by a voltmeter 21.

Patent GB-368935-A (GB)
Title: Improvements in the manufacture and production of aliphatic alcohols
IPC: C07C29/04
Filed: 1931-02-05
Abstract: Aliphatic alcohols are obtained by the reacting olefines with steam in the vapour phase at temperatures not exceeding 350 DEG  C. and in the presence of catalysts comprising metallic sulphates having an acid reaction.  Suitable sulphates are acid sodium sulphate, acid potassium sulphate, and aluminium sulphate.  The catalysts may be used either alone or in admixture with one another, or in conjunction with catalysts or promotors known to promote the reaction between olefines and organic acids.  Carriers composed of materials not having an alkaline reaction may be employed.  The reaction temperatures are preferably between 100 and 250 DEG  C.  Atmospheric pressure, or pressures up to 50 atmospheres or more may be employed. The mixtures of olefines and steam may be passed over the heated catalyst or forced through the catalysts when these are in a fluid condition.  Examples are given, in which mixtures of ethylene and steam are passed over acid sodium sulphate or pumice at temperatures of 150 and 160 DEG  C., with the production of ethyl alcohol, the unconverted ethylene being recirculated.  When treating homolognes of ethylene such as propylene or butylene, the temperature and concentration of the acid sulphate on the carrier is progressively less, the greater the molecular weight of the olefine.  The Provisional Specification mentions 500 DEG  C. as an upper limit for the reaction temperatures, and the use of pressures up to 250 atmospheres.

Title: Improvements relating to hopper feeding apparatus, more particularly for mixing machines
Inventor: BUCK LEON EDWIN
IPC: B28C7/08
Filed: 1949-02-11
Abstract: 680,622. Hoppers for feeding material. WINGET, Ltd. May 11, 1950. [Feb. 11, 1949] No. 3860/49. Class 78 (i). A hopper which is movable between a filling position and a position of emptying into an associated apparatus is movably mounted at least in part on a support member which is itself movably connected with the frame of said apparatus, whereby during the emptying of the hopper said support member is adapted to be raised by toggle links and thereafter dropped onto stops, so giving a jolt to the hopper to assist in the discharge of material from it. The hopper 4, Fig. 1, is raised and lowered by the usual cable 5 so as to deliver material, shovelled into it in its lower position, into the mixing drum 2. The hopper is pivotally mounted at each side at 25 to a structure 26 which is itself pivoted at 30, Fig. 3, to a plate 21 secured to an upright 22 of the mixer frame. The structure 26 consists of two spaced plates made rigid by a cover plate 27 and sleeves 28 and 31 for the pivots 25 and 30. A pivot pin 43 is also mounted between the plates and a sleeve 44 carrying a link 42 is mounted on it. The link 42 is pivotally connected at 47 to a second link 46 which is in turn pivoted freely on a shaft 41, thus forming a toggle. Shaft 41 has a plate 56 secured to it and is also provided with a handle 40, Fig. 1. Upon movement of the handle one or other of the abutments 57, 58 of the plate 56 engages the pivot 47 to break or align the toggle. The hopper 4 is raised with the toggle broken (not shown), the structure 26 resting on an inclined face 24 of the plate 21. During the emptying, the hopper is given a jolt by first moving handle 40 so as to align the toggle, Fig. 3, the toggle being held just beyond the aligned position by means of a roller 52 on an extension 46a of link 46 engaging the link 42, and thereafter moving the handle 40 so that abutment 57 engages pin 47 so as to break the toggle whereupon the structure 26 and with it the hopper 4 drop until arrested by the face 24. The lost motion of pivot 47 between the abutments 57 and 58 prevents any jar being given to the operator holding the handle 40.

Title: Improvements in dynamo-electric machinery
IPC: H02K9/06
Filed: 1930-02-05
Abstract: 335,496. Associated Electrical Industries, Ltd., (Assignees of Bollinger, P.). Feb. 6, 1929, [Convention date]. Armatures and field magnets, cooling and ventilating; casings; machines with two or more armatures.- In a commutator machine, the cooling fluid enters the armature spider at the non-commutator end and passes longitudinally under the armature core to the commutator end, where it is directed outwardly and returns through axial ducts in the armature core to the end of the machine at which it enters. The flow of fluid may be maintained during this passage by impeller means within the spider. Since the spider at the commutator end need not provide an air entry the commutator end bearing may project within the overhang of the commutator. Fig. 3 shows in sectional view the application to a locomotive motor in which two motors are located side by side in a common casing and.drive a common axle. A blower arrangement, not shown, located on the top of the casing, forces air into the motors. The air for cooling the armature passes through a passageway 33 to the armature spider where its velocity is maintained by the fan action of the arms 27. It reaches the passage alongside the guide 28, where impeller blades 36a maintain a steady flow, passes through the armature ducts 31, discharges into a space 35, where it passes over the stator leads 35, and leaves through the circumferential outlets 16 of the frame. The cross-section of this entire path decreases substantially as the air progresses. In order to prevent back pressure around the bearing, an opening 38 is provided in the flange 28 to allow some air to flow out over the bearing. The air for cooling the stator, entering by the passage 17 divides, one portion passing over the stator windings and commutator to the outlet 23, whilst the other portion passes towards the driving end of the motor and leaves with the armature air. The commutator structure is separate from the armature core and access may be had to the loose commutator V-ring 43 which can be put on the front end of the commutator. The flange 28, which is formed as an integral part of the armature spider, seals the rear end of the commutator against oil and moisture which may be brought in by the armature cooling air.

Title: Apparatus and Process for Producing Tubular Thermoplastic Film
IPC: B29C48/03
Filed: 1967-01-26
Abstract: 1,175,901. Nip rolls for blown tubular film. PETRO-TEX CHEMICAL CORP. 26 Jan., 1967 [26 Jan., 1966], No. 4032/67. Heading B5B. An apparatus for flattening inflated tubular films of thermoplastic polymeric material without creasing the edges of the flattened film comprises a pair of contra-rotating co-operating parallel nip rolls providing between them a centre section which receives and flattens the centre portion of the inflated film, one of the rolls having relieved non-contacting circumferential sections at each end of the centre section or one roll having a relieved section at one end of the centre section and the other roll having a relieved section at the other end of the centre section, such that the edges of the inflated film are also flattened without creasing by forming parallel cushions which are in communication with the interior of the tubular inflated film travelling towards the nip rolls and consequently inflated with the gas inflating the tubular portion of the film. As shown in plan in Fig. 2, a pair of nip rolls according to the invention comprise two cylindrical rolls 21 and 22 of equal diameter fixedly mounted in shafts 27 and 26, the roll 22 being of constant diameter along its length and the roll 22 having two circumferential relieved portions 28 located near the ends of the roll. The diameters of the centre section 29 and the two end sections 31 of the roll 21 are equal to the diameter of the roll 22 which is usually driven, roll 21 being usually an idler roll. The function of the end sections 31 of the roll 21 are to prevent bowing of the roll 21, since the end sections 31 contact, or almost contact, the roll 22. The depth of the relieved sections 28 is generally about 5 to 20 times the wall thickness of the inflated tubular film. The roll 21 may have the shape shown in Fig. 3, the portions 32 of the roll of smaller diameter in this case extending outwardly from the centre section 33 to the ends of the roll. Provided that the length of the centre section 32 is about 85 to 95% the total length of the roll, bowing or bending is not noticeable and the end sections 31 shown in Fig. 1 may be omitted. The film producing apparatus may be provided with means for directing streams of refrigerated air on to the two longitudinal strips of the inflated film which will form the two edges of the flattened film when the film is passed through the nip rolls. The film material may be polymers of alpha olefines or diolefines having the general formula R-CH=CH 2 , wherein R preferably has from one to 12 carbon atoms and is an aliphatic, aromatic or cycloaliphatic saturated or unsaturated radical. The polyolefine used may be butene-1, 4-methylbutene-1, or 5-methylpentene-1.
