Title: Improvements in or relating to lifting dogs
IPC: B66C1/54
Filed: 1923-04-13
Abstract: 216,637. Cammell, Laird, & Co., Ltd., Allan. J. M., Loving, H. C., and Miley, P. April 13, 1923. Lifting-dogs of the kind in which the pivoted dog 3 is deflected by contact with the load 1 and then returned by gravity or a spring to engage the load, are provided with means for deflecting the dog a second time and to a greater extent by lowering it with respect to the load. A catch is provided lor holding the dog in the deflected position until it is lifted clear of the load. The dog 3, Fig. 1, is pivoted at 4 and has a load-engaging shoulder 8. The second deflection is caused by the engagement of the surface 9 with the projection 2 on the load, and the dog is retained in the new position by the engagement of the shoulder 15 of the catch 10, Fig. 3, with a pin 12 which passes through a curved slot 13 in the bracket 5 concentric with the pivot 4. The catch 10 is pivoted at 11 and carries a roller 17 which disengages it when the dog is raised. The catch may be held inoperative or pressed towards the pin 12 by a spring-controlled plunger 18 bearing on shaped faces of the fixed pivot 11, Fig. 1. In a modification for lifting objects not having a projection 2, the pivot 4, Fig. 6, is at the lower end of the dog and the load is engaged by a curved surface 8. In both forms two dogs with their jaws faced outwards are adjustably mounted on a bar 6 connected to lifting tackle. When the dogs are used for lifting and centreing tyres, &c. each dog is adjustably mounted on one of a series of bars 6, Fig. 8, radiating from a common central boss 21 which may be hollowed to engage a fixed centreing pin 22 on the machine.

Title: Improvements in or relating to artificial threads
IPC: D06M11/62
Filed: 1932-04-08
Abstract: Artificial threads composed of a number of individual filaments are subjected to the action of swelling agents so that the filaments are welded together.  The treatment may be such that coalescence is complete, or so that the outer filaments of the bundle are welded together to form a covering round the filaments in the interior. Alkali hydroxides, sulphuric acid, phosphoric, hydrochloric, or nitric acid, or a mixture of acids, or zinc salts, thiocyanates, or ammoniacal copper oxide, may be used as swelling agent.  Alcohols, heterocyclic bases, or formaldehyde may be added to the swelling agent.  The treatment may take place at low or raised temperature. The threads may be of regenerated cellulose or of a cellulose ester, and they may contain continuous filaments or staple fibres.  Two- or multi-ply twisted threads of homogeneous or mixed artificial fibrous material with or without natural fibres may be treated.  Crinkled effects are obtained when the components behave differently towards the swelling agent. Differential dyeing effects may also be obtained. The material may be subjected to longitudinal tension during swelling and coalescing.  The products may be used as artificial horsehair or straw.  In an example, five-ply cuprammonium artificial silk is passed through strong caustic soda solution, washed, neutralized, and dried.  A stiff lustrous thread is obtained.  In another example, a mixed twisted thread of cuprammonium artificial silk and mercerized cotton is treated with strong sulphuric acid to form a stiff, crinkled, dull thread.  In another example, viscose thread is treated with strong sulphuric acid containing formaldehyde to form a stiff, translucent, and lustrous thread. In another example, five-ply cellulose acetate thread is treated with calcium thiocyanate solution to form a stiff lustrous thread.

Title: Method for the manufacture of agglomerates from a basic or hyperbasic mixture of iron ores
IPC: C22B1/16
Filed: 1968-03-04
Abstract: 1,220,521. Iron ore agglomerates. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 4 March, 1968 [17 March, 1967], No. 10332/68. Heading C1A. Agglomerates are manufactured from a basic mixture of iron ores, by maintaining the alumina, silica and lime in such proportions as to maximize the production of alumino-silicated ferrite of lime (ASFL), and varying the amount of solid fuel within the range 3-8% by weight to keep the amount of ASFL as large as possible. The ASFL preferably has the formula mFe 2 O 3 : nSiO 2 : pAl 2 O 3 : 5CaO, where m+n+p is substantially 12. The mixture may be sampled at intervals, X-ray emission used to measure the concentration of ASFL, and this used to dictate the amount of solid fuel to be added. Magnetic permeability measurements may also be used in the same way. Preferably, the magnetic permeability is used as a rough guide, because of the relative speed of this measurement, and the X-ray method used less frequently to provide finer control, and to calibrate the magnetic permeability measurement.

Title: Improvements in silde bearing for machine tools
Inventor: ATHERTON JOHN
IPC: B23Q1/38
Filed: 1963-03-16
Abstract: 1,076,404. Machine tool details. WILLIAM ASQUITH Ltd. Jan. 10, 1964 [March 16, 1963], No. 10498/63. Heading B3B. [Also in Division F2] A method of compensating for droop or lateral deflection of a member supported hydrostatically by a slideway comprises controlling the thickness of the oil film at any one or more predetermined areas between the bearing surfaces. A ram (10), Fig. 4 (not shown), is supported on bearings pads (32, 33, 34, 35) in a housing (11). The flow of oil to the pads is controlled by a reference pad (31) which works in conjunction with a diaphragm restrictor (36) to produce an oil pressure proportional to the oil flow which will support the ram as required. The said pressure is used to control equalizing valve (37) and adding valve (38) which regulate oil flow to pads (32, 33 and 34, 35) respectively. Equalizing valve (37) (Fig. 5, not shown) is designed to ensure that the oil pressure leaving the valve is equal to the oil pressure produced by reference pad (31), Fig. 4 (not shown). Adding valve (38) (Fig. 6, not shown) is designed to increase the pressure of oil flowing to pads (34, 35), Fig. 4 (not shown), when the reference pad pressure decreases and reduce the oil pressure when the reference pad pressure increases. If a load is applied to the ram to close the gap at the reference pad, which will decrease the thickness of the oil film, the hydraulic resistance of the pad will increase and a pressure rise will occur. This pressure rise registers upon the equalizing valve which increases oil flow to pads (32, 33). Simultaneously the pressure rise acts on the adding valve which causes a drop in pressure applied to pads (34, 35). If the end of the ram droops, this is compensated for by introducing an additional flow of oil from a droop compensator (39) via a conduit (96) to the reference pad circuit. When additional oil is added to the reference pad circuit, pressure increases at the reference pad (31) which operates the valves (37, 38) to increase oil flow to bearing pads (32 and 33) and reduce oil flow to pads (34 and 35). Hence the ram is lifted until the restriction at reference pad (31) is such that the total oil flowing through the circuit produces the predetermined pressure to support the ram.

Title: Improvements in, or relating to, calorimeters
IPC: G01N25/26
Filed: 1928-04-10
Abstract: 315,285. Scholes, G. E. April 10, 1928. Lids and covers.-To make a fluid-tight joint between the body and the cover of a bomb calorimeter, particularly of the kind described in Specification 236,980, [Class 97 (iii), Thermometers &c.], a serrated annular unyielding jointing surface is formed on the end of the body and a corresponding Jointing surface is formed on a resilient member which extends from the interior of the wall of the cover and yields elastically when jointing pressure is applied; the resilient member is so disposed that the side on which the jointing surface is formed is freed from, while the opposite side is subjected to, the fluid pressure within the vessel. A thin washer of lead &c. is interposed between the two sets of serrations. In Figs. 1 and 3 the serrated resilient member R on the cover is in the form of a ring of cantilever section and co-operates with the serrated base of a spigot a' integral with the body A of the calorimeter, the lead &c. washer C being inserted between the sets of serrations. The portion b<1> of the cover extends beyond the member R, its interior surface being a sliding fit over the part a<2> of the body while its exterior is threaded for engagement by the closing nut S. A recess T is thus provided to which the fluid pressure within the calorimeter does not extend, so that the said pressure acts only on the lower surface of the member R. The joint described is a metal-to-metal joint and is for use when gases which would affect a rubber &c. packing ring are generated in the calorimeter. When such gases are not to be generated, a rubber &c. ring c<3> of the kind described in Specification 236,980, [Class 97 (iii), Thermometers &c.], may be fitted between the serrated ends r<1>, a<5> of the recess T as in Fig. 4, the recess being then in communication with the interior of the body.
