IPC: F16F7/10
Filed: 1973-05-10
Abstract: 1391388 Boring bars; chucks REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 10 May 1973 [28 July 1972] 22327/73 Headings B3B and B3C [Also in Division F2] Vibrations of a rotating shaft, e.g. a toolholder or boring shaft 2 are damped by a body 7 in mercury 8 in an axial cavity 4 in the shaft. The cavity may be situated ahead of or behind the boring head. The body 7 is a cylinder of steel or heavy sintered metal, whose density is less than mercury. As the shaft rotates, the mercury is displaced by centrifugal force to the periphery of the cavity and centres the body. The body 7 has annular peripheral recesses 9 (Fig. 2) to increase the area of contact between it and the mercury to increase the damping due to friction. The area of contact can be varied by filling the space between the cavity walls and the body with mercury to a greater or lesser degree, but preferably the space is completely filled.

Title: Improvements in or relating to process for purification of relaxin by ion exchange
IPC: F01K9/00
Filed: 1954-08-04
Abstract: Relaxin preparations containing impurities having an isoelectric point higher than that of relaxin are purified by bringing an aqueous solution having a pH greater than the isoelectric point of relaxin, say 7-8.6, into contact with a carboxylic acid type cation exchange resin buffered to the same pH, and washing unabsorbed material from the resin with a buffered solution of pH not greater than that of the buffered resin thereby recovering the purified relaxin.  The resin may be regenerated by eluting the absorbed impurities with acid. Relaxin preparations containing impurities of lower isoelectric point are purified by bringing an aqueous solution of lower pH than the isoelectric point of relaxin, say 4.5-7, into contact with the said resin buffered to the same pH, and washing unabsorbed material from the resin, purified relaxin being then obtained by washing the resin with acid.  Suitable resins are those formed by condensation of a phenolic carboxylic acid and an aldehyde, or preferably, copolymers of acrylic or methacrylic acid and divinyl benzene wherein the latter constitutes 2 1/2 -5 per cent of the resin composition.  Prior to or after purification, electrolytes are removed by dialysis, or by treatment with a sulphonic acid type cation exchange resin (acid form), followed by treatment with an anion exchange resin.  The product may be freeze-dried.

Title: Improvements in and relating to latches for doors and the like
IPC: E05C1/14
Filed: 1935-08-15
Abstract: 439,160. Latches. HAMILTON, R. H., 16, Beverley Street, St. Albans, Christchurch, New Zealand. Aug. 15, 1935, No. 23013. Convention date, Aug. 15, 1934. [Class 44] A latch, particularly for a motor-car door, is moved into engagement with the catch plate by a member movably mounted on the latch housing and adapted to be engaged by a projection on the catch plate as the door is closing to effect the movement of the latch. The latch has a wedge-shaped end so that the door is pressed firmly on to its frame as the latch is advanced. An arm 8 pivoted about an axis 9 has a crank 14 connected by a link 15 to a lever 16 which is connected by a link 19 to a cam 11 pivoted to the latch casing at 10. Normally a formation 21 on the end of the arm 8 engages over the end of a latch 4 and retains it in its retracted position but as the door'is closed the arm 8 encounters a projection 6 on the door frame and the lever 8 is moved to displace the cam 11 which acts on the inner end of the latch to force it outwards. Preferably the link 15 is made resilient to ensure steady contact between the catch plate and a sloped end 20 on the latch. The cam surface is shaped so that the bolt cannot be forced to disengaged position except during the initial outward movement and the outer end of the latch has a bevel 22 so that should the door be closed with the latch slightly projecting it can be forced back by striking the catch plate. To withdraw the latch a lever 27 on a handle spindle 26 can be brought into engagement with the lever 16 to move the cam 11 which has an inner cam surface 23 engaging a roller 24 on the end of the latch. The link 19 may have a sliding connection at the cam end and be normally kept extended by a spring 29 which acts to cushion over-vigorous movements of the handle. As alternatives to the various elements described, the latch may be pivoted instead of sliding, the member 8 and cam 11 may slide instead of being pivoted and the cam may be replaced by a lever device. A key lock may be used for locking the handle.
