Title: Improvements in interlocking mechanisms for enclosed electric switches
IPC: H01H21/06
Filed: 1954-06-23
Abstract: 763,117. Snap action switches; switch covers. CRABTREE & CO., Ltd., J. A., WINTLE, T. D. G., and MIDDLETON, E. June 17, 1955 [June 23, 1954], No. 18370/54. Class 38(5) In an electric switch of the kind in which the cover 1 cannot be removed when in the "on" position a handle 7 is attached to a spindle which projects through a bush 4 in the cover and carries a pin 10 to which is attached a torsional snap action spring 11 the pin also engaging a sleeve 9, which is provided with slots 9a which receive a transverse pin 13 on a switch spindle 12; a bracket 2 secured to the cover and disposed over the sleeve 9 has an elongated slot 2b which will accept the transverse pin 13 of the switch spindle in the " off " position only, so that the cover and associated mechanism may be disengaged from the operating spindle only when the switch is "off." The snap action spring 11 has one end secured to the cover at 16 and the other end to a flat end 10a of the pin 10, the movement being limited by side projections 2d of the bracket 2. The handle 7 may be padlocked in either of the two operating positions to lugs on a front plate 15 (not shown). Specification 719,811 is referred to.

Title: Improvements in the construction of floating vessels
IPC: B63B3/00
Filed: 1923-07-17
Abstract: 223,299. Isherwood, J. W. July 17, 1923. Framing.-In ships built on the longitudinal system and having transverse bulkheads the longitudinals C on stem and centre line bulkhead G as well as the horizontals on the transverse bulkheads A stop short of the sides of the ships and the bulkheads, the usual corner brackets being eliminated. The projecting end spans of the longitudinals and horizontals have usually a less length than that between the webs or transverses B, but in some cases only one web or transverse is interposed between adjacent bulkheads. In this case, as well as in others in which two transverses occur, the longitudinals are bracketed to the intervening webs. The free ends of the longitudinals may be stiffened by reverse bars or by back angles. In certain cases the longitudinals may be placed outside the skin plating and the webs inside. Specification 2588/06 is referred to.

Title: Flexible force-transmitting mechanism
IPC: F16C1/26
Filed: 1965-05-03
Abstract: 1,080,156. Bowden mechanism. R. RICHOUX. May 3. 1965 [May 6, 1964; July 27. 1964], No. 18541/65. Heading F2K. In a Bowden mechanism having a flexible flat metallic inner member 1 and an outer sheath 4, friction is reduced by balls 13 engaging directly with the member 1 and sheath 4. The balls 13 and member 1 are so dimensioned to permit transverse movement thereof within the sheath 4 and thus prevent jamming. The balls 13 are spaced axially by a wire cage 17 shaped as shown. The outer sheath 4 may, as shown, be plastic or may, Figs. 10-14 (not shown), be formed by helically winding a flexible metal strip (41) which may be surrounded by a plastic cover (45). The inner member (1) has grooves (11, 12), Fig. 2 (not shown), which engage the balls (13). The cages (17) on either side of the inner member (1) are connected for conjoint axial movement either by forming them integrally (Fig. 5, not shown) or by connecting both cages to a sleeve (32) (Fig. 6, not shown). In Fig. 7 (not shown) the plastic outer sheath (4) is externally threaded at one end and is screwed into a metal sleeve (6) which adjustably carries a ball element (37) engaging a spherical seat (38) in a fixed member (8). In Fig. 8 (not shown) one end of the sheath is thickened and externally threaded to adjustably engage the threaded bore of a bracket (39) pivoted to a fixed member at (40). In Fig. 9 (not shown) the sheath (4) has an integral spherical portion which engages a spherical seat in a fixed member.
Patent GB-754885-A (GB)
Title: Recovery of heparin
Filed: 1954-06-24
Abstract: Heparin is recovered from an alkaline or substantially neutral aqueous solution containing also a protein by adding a soluble salt of an alkali metal, or of ammonium, or of an alkaline earth metal to said solution, acidifying the solution to precipitate the protein, removing the protein and recovering the heparin from the remaining solution.  The solution of the proteinheparin mixture may have a pH between 7 and 10.  Sufficient soluble salt may be added to produce an anion concentration of at least about one mol. per litre.  Suitable salts which may be used are alkali metal and ammonium citrates, halides, acetates, sulphates and thiocyanates, and alkaline earth metal halides, acetates and citrates, e.g. sodium chloride, sodium thiocyante, calcium chloride and acetate, and ammonium sulphate and citrate may be used.  When sodium chloride is used, the solution may be acidified to a pH of less than 4, e.g. when between about 100 grams and about 150 grams of sodium chloride is used, the solution may be acidified to a pH of about 2.5 to precipitate the protein. The heparin solution containing protein may be obtained by autolyzing heparinbearing animal tissue, extracting the autolyzed tissue with an aqueous solution of alkali, e.g. ammonium sulphate and sodium hydroxide, heating the mixture, filtering to remove the coagulated substance, acidifying to precipitate a protein-heparin complex which is dissolved in water at a pH of at least 7 to form the solution for the above process.  The process is applicable to heparin mixtures containing denatured or native proteins.  The temperature at which protein coagulation is effected may vary from about 0 DEG  C. to about 100 DEG  C.-heating during or after the acidification being particularly useful.  Suitable acids which may be used for the acidification are strong inorganic and strong organic acids such as sulphuric, hydrochloric and trichloroacetic acids.  The heparin is preferably precipitated from the protein-free solution by adding a water-miscible organic solvent such as methyl or ethyl alcohol or acetone.  When the soluble salt used in the above process is not very soluble in ethyl alcohol or acetone, it is desirable to subject the filtrate to dialysis to remove the salt before the heparin is precipitated. Alternatively, the precipitated heparin containing the salt may be dissolved in water, the solution subjected to dialysis to remove the salt, and reprecipitating the heparin with alcohol or acetone.  The process is suitable for the purification of heparin, e.g. impure heparin can be mixed with an acid precipitable protein such as casein, the mixture is acidified and the resulting precipitated heparin-protein complex can then be treated by the above process.  A number of detailed examples are given.  U.S.A. Specification 2,623,001 is referred to.

Abstract: 858,353. Roadside tyre-inflating plant. PNEUMATIC COMPONENTS Ltd. May 29, 1959 [June 11, 1958], No. 18600/58. Class 116 [Also in Group XXIX] In air dispensing-apparatus as described in Specification 766,354 and as modified by Specification 838,932 the exhaust from the intermittently-operated control valve D controlling the main valve G supplying compressed air from the main 10 to the tyre connector F through lines 17, 18, 20 passes through a line 24 to a striking unit H to produce an audible signal when the apparatus is operating. The striking unit comprises a mounting block 47, Fig. 3, having an upstanding tube 48 housing a closely fitting ball 50 which, when at the bottom of the tube, closes a bore 51 at the outlet end of the line 24. On each closing of the valve D, air exhausted through the line 24 raises the ball 50 into engagement with a bell or gong J to give an audible signal, air then exhausting to atmosphere through a hole 54. A small bleed hole 55 near the bottom of the tube ensures that air will be exhausted even should the hole 54 be closed by a film of oil. The main valve G includes a spring- loaded valve member 40, Fig. 2, controlling flow between the lines 17, 18 and it is actuated by a diaphragm 31 which receives impulses of air from a line 16 every time the valve D opens. Specifications 772,257 and 775,989 also are referred to.
