Title: Improvements in and connected with processes for the treatment of blubber and fibrous-containing substances of land and sea mammals
IPC: D01F4/00
Filed: 1938-05-13
Abstract: 501,703. Removing fat from blubber and similar materials to obtain spinnable fibre. FAUTH PATENT AKT.-GES. May 13, 1938, No. 14244. Convention date, June 21, 1937. [Class 91] Whale blubber and similar fibre-containing substances are freed from fat by comminuting, heating the comminuted material at 30 to 40‹ C. and separating the oil and water, leaving the fibrous tissue which is spinnable. The separation of liquid constituents may be assisted by adding salt such as sodium or magnesium chloride, or alcohol, and the temperature is controlled below 40‹ C., whereby the physical properties of the fibrous constituents are not impaired. The liquid constituents are then removed by pressing or centrifuging. The fatty parts of seals and pigs may also be treated. Specification 458,975, [Group II], is referred to.

Title: Improvements in and relating to the Finishing of Articles of Clay-Ware.
Inventor: COLCLOUGH RAYMOND HENRY
IPC: B24B19/00
Filed: 1967-03-30
Abstract: 1,183,753. Finishing articles of clayware. JAMES BROADHURST & SONS Ltd. 1 July, 1968 [30 March, 1967], No. 14440/67. Heading B3D. Articles of clayware are finished by supporting a number of articles one upon another in a tier or bung, so that the articles are held securely in a horizontal position, rotating the bung as a unit about a vertical axis, bringing a towing tool into contact with the periphery of the bung at one level and moving the tool vertically so that it engages operatively with the peripheries of all the articles in the bung. The finishing may be the smoothing off of the edges or rims of flatware, e.g. plates and saucers. The articles may be supported with their concave sides uppermost, the traverse of the tool beginning at the bottom and proceeding upwards. The articles may be supported with their convex sides uppermost, the traverse of the tool beginning at the top and proceeding downwards. The tool is preferably retracted at the end of its traverse, making the return movement out of contact with the articles; alternatively the tool may act in both directions of travel. The tool is preferably rotated either positively or by frictional engagement with the articles. A head 1, mounted on a vertical spindle which is rotated intermittently for sufficient periods, is shaped to carry a bung of plates or saucers 2, which are retained by a freely rotatable member 3, lowered when required so as to rest on the top article. A towing tool 4 comprises flat rings of flexible abrasive material, e.g. expanded nylon, separated by rigid or flexible washers of smaller diameter. The tool may be rotated by the articles but is preferably positively rotated by driving gear mounted in a housing 5 and actuated from a driving spindle carried in housings 6, 7, the mechanism including a cam or a fluid pressure cylinder for effecting raising and lowering. A compressed air pipe 8 has holes through which air jets are directed at the articles where they are being acted on by the tool to blow away dust and fragments; suction is applied to the apparatus to carry these away, and the whole may be mounted in an enclosure having a door for loading and unloading. The movements of the mechanisms and their stopping at the completion of a cycle of operations may be controlled automatically in a timed sequence if desired, so that only the placing and removal of the bungs and the initiation of each cycle of operations by means of a starting button need be performed manually. The drive to the tool may be derived from the same motor as the drive to the head 1, e.g. by a belt and pulleys connecting the drive to the head 1 with a drive head 9 for the tool gearing. At the conclusion of a towing operation the tool and its driving gear swing bodily away from contact with the ware and the member 3 is raised.

Abstract: 245,346. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). June 5, 1925. Feeding webs.-In an apparatus for controlling the unwinding of a web in a printing or other machine, a friction brake engages the surface of the web roll to exert a normal tension on the web and means are provided for suddenly increasing the pressure of the brake on the roll to prevent overrunning of the roll. The friction brake may be of the usual form comprising one or more belts 14 driven at the same speed as the webs and passing round pulleys 20 on a driven-shaft 15 and round guide pulleys 21 carried by arms 22 freely mounted on the shaft 15. The means for increasing the pressure of the belts 14 upon the roll comprises a pneumatic cylinder 28, the piston rod 33 of which is connected to a rod 27 carried by arms 24 projecting from the adjacent arms 22 of a pair of belts 14. A two-way valve 32 for controlling the flow of air from a supply pipe 31 to the ends of the cylinder 28 is operatively connected by chains 39 to solenoids 40 in circuit with the electrical controlling devices of the machine so that upon stopping the machine, air is admitted to the cylinder 28 to operate the brake to stop the rotation of the roll. The amount of the increase in the pressure of the brake may be varied in accordance with the diameter of the roll by connecting one of the arms 24 by a rod 43 to a throttle valve 42 in the inlet pipe to the cylinder so that as the roll is reduced the valve is gradually closed. The rod 27 is movable axially so that it may be disconnected from one of the arms 24 if it is desired to throw the corresponding belt 14 out of operation.

Title: Improvements relating to alloys for use at high temperatures
IPC: C22C19/00
Filed: 1943-09-17
Abstract: A nickel-base, iron-containing alloy, suitable for the manufacture of articles and parts used at high temperature under stress, contains 10-25 per cent of chromium and 1.5-5.0 per cent of titanium with or without any one or more of the elements aluminium, niobium and tantalum, and the remainder nickel.  The iron content of the alloy is so low that no significant amount of embrittling phase is produced even if the alloy is heated to 1000 DEG C., cooled to room temperature at a rate sufficiently fast to retain the solution created during heating, reheated to 600 DEG C.-800 DEG C. and subjected to prolonged heating at 650 DEG C.-900 DEG C. The maximum permissible amount of iron is related to the chromium content by a graph accompanying the Specification.  The total content of titanium and the aluminium, niobium and tantalum contents, measured in terms of titanium, must be at least 3 per cent and does not exceed 10 per cent.  For this purpose 1 per cent of niobium is regarded as equivalent to 0.5 per cent titanium, 1 per cent of aluminium is equivalent to 1.25 per cent titanium and 1 per cent tantalum is equivalent to 0.25 per cent titanium.  The nickel may be partly replaced by cobalt, so that the alloy contains up to 45 per cent cobalt.  Up to 2 per cent each of copper, manganese, tungsten, and/or vanadium, up to 5 per cent of molybdenum, up to 1 per cent of nitrogen, up to 2 per cent of silicon may also be present in the alloy.  Specifications 572,779, 572,861 and 583,845 are referred to. Reference has been directed by the Comptroller to Specifications 572,779 and 572,861.

Title: Automatic control for hydraulically driven diaphragm-operated compressors and pumps subjected to very high pressures
IPC: F04B43/067
Filed: 1963-04-18
Abstract: 1,003,596. Diaphragm pumps. MASCHINENFABRIK BURCKHARDT A.G. April 18, 1963 [April 24, 1962], No. 15404/63. Headings F1A and FIN. In a high pressure diaphragm compressor or pump wherein the diaphragm I is actuated by hydraulic pressure generated in a chamber 7 by a plunger 8 and wherein the chamber 7 is of greater capacity than the chamber 6 thereby resulting in a sudden pressure rise in chamber 7 after completion of the delivery stroke of the diaphragm, and continued forward movement of plunger 8, means is provided whereby after a predetermined pressure rise in chamber 7 but below that at which the diaphragm is likely to be ruptured the plunger stroke is automatically reversed. The plunger 8 which has spaced packings 9, 10 is itself actuated by hydraulic pressure alternately supplied to and exhausted from opposite sides of a piston 11 by a main valve (not shown) which is reversed when the supply pressure on the underside of piston 11 reaches a value proportionate to that in chamber 7 and serves to displace a control piston 30 linked to said main valve. In operation an extension of the plunger 8 carries a cam 26 which for a short interval during the constant pressure delivery period of the compressor opens a tapping-off valve 25 to allow passage of supply fluid to an accumulator 28 and to the other side 32 of the piston 30 thereby assisting a spring 33 to hold said piston against displacement until overcome by said pressure rise. A cut-off slide valve 29 prevents back flow from the accumulator during the return stroke of plunger 8 and piston 11. After completion of the suction stroke of the diaphragm 1 continued return stroke of plunger 8 results in an hydraulic pressure drop in chamber 7 to a value beneath that prevailing between packings 9, 10. Fluid then leaks into chamber 7 and pressure is restored by displacement of differential pistons 43, 44 acted upon by hydraulic fluid from an accumulator 41 which has previously been connected to the underside of piston 11 for a short interval during the constant pressure exhaust period of the compressor. A valve 47 connects the amplifier 43, 44 to atmosphere during the forward stoke of the compressor and a valve 42 is closed during this period to prevent back flow of fluid from accumulator 41.
